- Abstract
Background: Although class attendance is linked to academic performance, questions remain about what determines students' decisions to attend or miss class. Aims: In addition to the constructs of a common decision-making model, the theory of planned behaviour, the present study examined the influence of student role identity and university student (in-group) identification for predicting both the initiation and maintenance of students' attendance at voluntary peer-assisted study sessions in a statistics subject. Sample: University students enrolled in a statistics subject were invited to complete a questionnaire at two time points across the academic semester. A total of 79 university students completed questionnaires at the first data collection point, with 46 students completing the questionnaire at the second data collection point. Method: Twice during the semester, students' attitudes, subjective norm, perceived behavioural control, student role identity, in-group identification, and intention to attend study sessions were assessed via on-line questionnaires. Objective measures of class attendance records for each half-semester (or "term") were obtained. Results: Across both terms, students' attitudes predicted their attendance intentions, with intentions predicting class attendance. Earlier in the semester, in addition to perceived behavioural control, both student role identity and in-group identification predicted students' attendance intentions, with only role identity influencing intentions later in the semester. Conclusions: These findings highlight the possible chronology that different identity influences have in determining students' initial and maintained attendance at voluntary sessions designed to facilitate their learning.

Direct and moderation effects of swimming competence using an integrated model of self-determination theory (SDT) and theory of planned behaviour (TPB) were examined in two large-scale studies among young children. Specifically, we examined whether swimming competence had direct and moderation effects on social psychological variables of perceived need support, autonomous motivation, TPB social cognition constructs, and intention. In Study 1, using a cross-sectional survey of 4959 primary school children, swimming competence formed significant positive relationships with all model variables (β =.061 to.330, p <.05) except intention (β = -.009, p >.05), and its moderation effect on model parameters were small in size or not statistically significant. In Study 2, using a pre-post-test quasi-experiment among 1,609 primary school children, improvement of swimming competence was associated with change-scores in all model variables (β =.046 to.230, p <.05) except subjective norm (β =.049, p >.05). Swimming competence did not significantly moderate the parameter estimates of the integrated model (p >.05) at the change-score level. Findings indicate that swimming competence is associated with higher autonomous motivation; TPB social cognitions of attitude, subjective norm, and perceived behavioural control; and intention. However, swimming competence did not moderate the parameter estimates of the integrated model. [ABSTRACT FROM AUTHOR]

Skin cancer is highly burdensome, but preventable with regular engagement in sun protective behaviors. Despite modest effectiveness of sun-protective behavior promotional efforts thus far, rates of engagement in sun-protective behaviors remain low. More is needed to understand motivation for using sunscreen, wearing sun-protective clothing, and seeking shade. This study tested whether the links of intention and habit strength with behavior differed between sun-protective behaviors. It was hypothesized that sun protective behaviors would be predicted by both habit and intention and that intention-behavior associations would be weaker for people with stronger habits. Participants residing in Queensland, Australia (N = 203; 75.96% female; M age = 37.16 years, SD = 14.67) self-reported their intentions and habit strength about sun-protective behavior for the next 7 days. Participants were followed-up 7 days later to self-report their sun-protective behavior. Multilevel modeling, accounting for nesting of multiple behaviors within-person, revealed that habit moderated the intention strength – behavior association and this moderation effect did not differ as a function of which behavior was being predicted. People with strong or moderate habit strength tended to act in line with their intentions; however, for people with very weak habits (2 SD < M), there was less alignment between their intention and behavior. These findings suggest that habit plays a facilitative role in the implementation of strong sun protective behavior intentions. Interventions should consider how to encourage intention and habit to enhance sun-protective behaviors and reduce the burden of skin cancer from sun exposure.

This study examined the swimming competence of primary school children, and how it was related to swimming activity, non-fatal aquatic events, and demographic factors. Primary school students (N = 4959; female = 2705, male = 2241; age range = 5 to 14 years) across 28 schools in the 15 districts of Hong Kong completed the Swimming Competence Questionnaire, and questions about their swimming experience, non-fatal aquatic events, and demographic variables. Descriptive statistics showed that over 60% of children could swim more than 5m, but less than 50% could swim over 25m. Over 50% of children were able to perform some basic swimming skills (e.g., holding breath underwater, floating, poolside/kickboard kicking, and treading water). Swimming competence was positively predicted by the demographic factors (i.e., age, sex, family income, and parents' highest education level), swimming experience, learning experience, and swimming location. Treading water was the only factor of swimming competence that established asignificant negative association with non-fatal aquatic events. Current results can be used to target key groups to improve children's swimming competence and reduce non-fatal aquatic events; children from lower socio-economic backgrounds and with less swimming experience should be encouraged to participate in more formal learn to swim lessons.

Two studies were employed to test the reliability and validity of the Swimming Competence Questionnaire (SCQ) among primary school children. Study 1 was a cross-sectional survey in 4959 primary school children. Study 2 was a pre-post-test quasi-experiment among 1609 primary school children who underwent a 20-lesson learn-to-swim programme. In Study 1, exploratory structural equation modelling revealed excellent goodness-of-fit and scale reliability for a two-factor model comprising distance and skill factors, which supported the construct and convergent validity. SCQ scores were significantly and positively correlated with swimming outcomes (i.e., self-efficacy, intention, swimming frequency), which supported SCQ's concurrent and criterion validity. Average variance extracted for the SCQ factors exceeded cut-off criteria supporting discriminant validity. In Study 2, pre-test SCQ scores correlated significantly and positively with the SCQ scores, self-efficacy, intention, and swimming frequency at post-test, which supported SCQ's test-retest reliability and predictive validity. Positive intraclass correlation between SCQ scores and coach ratings at post-test provided evidence for SCQ's inter-rater reliability. SCQ scores significantly improved at post-test, which supported SCQ's ecological validity. In conclusion, findings indicate that the SCQ is a valid and reliable measure to assess primary school children's swimming competence, in terms of swimming distance and basic water survival skills.

This study examined an extended theory of planned behaviour (TPB), incorporating additional social influences, for predicting parents' and carers' decisions to visit the library with their young children. At Time 1, participants (N = 212) completed a paper-based questionnaire measuring the TPB constructs as well as group norm, parental role construction, social support (i.e. family and friend support), and psychological sense of community in relation to visiting the library. At Time 2, participants (N = 171) completed a telephone survey to measure behaviour over the previous six months. Attitude, subjective norm, perceived behavioural control, group norm, and parental role construction predicted intentions. Intentions and perceived behavioural control predicted follow-up behaviour. Results support the TPB and the role of group norm and parental role construction. The findings highlight the importance of social and cognitive factors in predicting parents' and carers' decisions to visit public libraries with their young children. [ABSTRACT FROM AUTHOR]

The current study aimed to test the validity of an extended theory of planned behavior model (TPB; Ajzen, 1991), incorporating additional self and social influences, for predicting adolescent moderate-to-vigorous physical activity. Participants (N = 423) completed an initial questionnaire that assessed the standard TPB constructs of attitude, subjective norm, and perceived behavioral control, as well as past behavior, self-identity, and the additional social influence variables of group norms, family social support, friends' social support, and social provisions. One week after completion of the main questionnaire, participants completed a follow-up questionnaire that assessed self-reported physical activity during the previous week. The standard TPB variables—past behavior, self-identity, and group norms, but not social support influences—predicted intentions, with intention, past behavior, and self-identity predicting behavior. Overall, the results provide support for an extended version of the TPB incorporating self-identity and those social influences linked explicitly to membership of a behaviorally relevant reference group.

Objective: To examine the motivational processes underpinning Australian older adults' physical activity. Method: Adults aged 65 years and over (N = 213) completed a questionnaire assessing autonomous motivation and theory of planned behaviour variables (attitudes, subjective norm, and perceived behavioural control), and a 2‐week follow‐up of their self‐reported physical activity (n = 165). Results: In a structural equation model, effects of autonomous motivation on intention were mediated by attitudes and perceived behavioural control, but not subjective norm. The model explained 60% and 46% of the variance in intention and physical activity, respectively. Conclusion: The findings add to current knowledge of motivational processes underpinning physical activity in older adults. Current results indicate that interventions where the value of regular physical activity can be internalised by offering activities that foster feelings of competence, autonomy, and relatedness may be important to consider in increasing physical activity levels of older adults, a group at risk of sedentary behaviours.

Objective: Pre-drinking, the practice of consuming alcohol prior to attending a subsequent event, increases the risk of alcohol-related harm, and is common in undergraduate student populations. The current study tested an integrated behaviour change model to identify the motivational, social-cognitive, and implicit predictors of pre-drinking. Design: University students (N = 289) completed an online questionnaire comprising measures of motivational and social-cognitive constructs related to reducing pre-drinking alcohol consumption and past behaviour, and an implicit association test for drinking identity. Participants reported their pre-drinking alcohol consumption at follow-up, 4 weeks from baseline. Main Outcome Measures: Self-reported pre-drinking alcohol consumption. Results: A variance-based structural equation model revealed that few model hypotheses were supported. Although the effects of past behaviour, perceived behavioural control, and implicit drinking identity, on follow-up pre-drinking alcohol consumption were statistically significant, the effect of intention was not. Conclusions: Current findings indicate pre-drinking alcohol consumption is associated with past behaviour, perceived behavioural control and implicit drinking identity, and no intentions to reduce pre-drinking alcohol consumption. The finding raise questions over the validity of applying the integrated model in this context. Interventions should consider these factors and attempt to facilitate the formation of intentions that lead to subsequent behaviour. [ABSTRACT FROM AUTHOR]

Objective:To assess the effects of conscious and non-conscious processes for prediction of older adults’ physical activity (PA), we tested a dual-process model that integrated motivational (behavioural intention) and volitional (action planning and coping planning) processes with non-conscious, automatic processes (habit). Method:Participants (N = 215) comprised community-dwelling older adults (M = 73.8 years). A longitudinal design was adopted to investigate direct and indirect effects of intentions, habit strength (Time 1), and action planning and coping planning (Time 2) on PA behaviour (Time 3). Structural equation modelling was used to evaluate the model. Results:The model provided a good fit to the data, accounting for 44% of the variance in PA behaviour at Time 3. PA was predicted by intentions, action planning, and habit strength, with action planning mediating the intention-behaviour relationship. An effect of sex was also found where males used fewer planning strategies and engaged in more PA than females. Conclusions:By investigating an integration of conscious and non-conscious processes, this study provides a novel understanding of older adults’ PA. Interventions aiming to promote PA behaviour of older adults should target the combination of psychological processes. [ABSTRACT FROM PUBLISHER]

Visiting the beach is a popular activity, but the risk of drowning is real. Drownings are preventable, and swimming between the patrol flags can save lives. The aim of this study is to understand the beliefs people hold in relation to this important water safety behaviour. Participants (N=514; females = 58%) who were residents of/visitors to coastal areas in South-East Queensland, Australia, completed a theory of planned behaviour belief-based questionnaire. The survey was designed to measure behavioural, normative and control beliefs guiding beachgoers' intentions to swim between the patrol flags. Controlling for age, gender and swimming ability, four critical beliefs (along with self-reported swimming ability) were identified as independently predicting intention. Specifically, the benefits of feeling safe and the cost of feeling limited in choice of where to swim, the social approval from partners and the inhibitor belief about better waves being outside the flags predicted intentions to swim between the flags. This study provides an understanding of the beliefs underlying Australian beachgoers' intentions to swim between the patrol flags. Attention to these targeted beliefs may assist in promoting more regular performance of this beach safety behaviour, thereby combating the increasing rates of drownings and surf rescues.

Objectives.To examine motivational and volitional factors for hand washing in young adults, using the Health Action Process Approach (HAPA) as a theoretical framework. Design.In a longitudinal design with two measurement points, six weeks apart, university students (N = 440) completed paper-based questionnaires. Main outcome measures.Prior hand washing frequency, self-efficacy, outcome expectancies, intention and action planning were measured at baseline, and coping planning, action control and hand washing frequency were measured at follow-up. Results.A theory-based structural equation model was specified. In line with the HAPA, the motivational factors of self-efficacy and outcome expectancies predicted intention, whereas the volitional factors of planning and action control mediated between intention and changes in hand washing frequency. Action control was confirmed as the most proximal factor on hand washing behaviour, thus representing a bridge of the planning–behaviour gap. Conclusions.Both motivational and volitional processes are important to consider in the improvement of hand hygiene practices. Moreover, the statistically significant effects for planning and action control illustrate the importance of these key self-regulatory factors in the prediction of hand hygiene. The current study highlights the importance of adopting models that account for motivational and volitional factors to better understand hand washing behaviour. [ABSTRACT FROM PUBLISHER]

Objectives: Preschool-aged children spend substantial amounts of time engaged in screen-based activities. As parents have considerable control over their child's health behaviours during the younger years, it is important to understand those influences that guide parents' decisions about their child's screen time behaviours.Design: A prospective design with two waves of data collection, 1 week apart, was adopted.Methods: Parents (n = 207) completed a Theory of Planned Behaviour (TPB)-based questionnaire, with the addition of parental role construction (i.e., parents' expectations and beliefs of responsibility for their child's behaviour) and past behaviour. A number of underlying beliefs identified in a prior pilot study were also assessed.Results: The model explained 77% (with past behaviour accounting for 5%) of the variance in intention and 50% (with past behaviour accounting for 3%) of the variance in parental decisions to limit child screen time. Attitude, subjective norms, perceived behavioural control, parental role construction, and past behaviour predicted intentions, and intentions and past behaviour predicted follow-up behaviour. Underlying screen time beliefs (e.g., increased parental distress, pressure from friends, inconvenience) were also identified as guiding parents' decisions.Conclusion: Results support the TPB and highlight the importance of beliefs for understanding parental decisions for children's screen time behaviours, as well as the addition of parental role construction. This formative research provides necessary depth of understanding of sedentary lifestyle behaviours in young children which can be adopted in future interventions to test the efficacy of the TPB mechanisms in changing parental behaviour for their child's health.Statement Of Contribution: What is already known on this subject? Identifying determinants of child screen time behaviour is vital to the health of young people. Social-cognitive and parental role constructions are key influences of parental decision-making. Little is known about the processes guiding parents' decisions to limit their child's screen time. What does this study add? Parental role construction and TPB social-cognitive factors influence parental decisions. The beliefs of parents for their child's behaviour were identified. A range of beliefs guide parents' decisions for their child's screen time viewing. [ABSTRACT FROM AUTHOR]- Published

Objective: To examine a mechanism by which social cognitive factors may predict fruit and vegetable consumption in long-haul truck drivers. Methods: Dietary self-efficacy, positive outcome expectancies, and intentions were assessed in 148 Australian truck drivers, and 1 week later they reported their fruit and vegetable consumption. A theory-guided sequential mediation model was specified that postulated self-efficacy and intention as mediators between outcome expectancies and behavior. Results: The hypothesized model was confirmed. A direct effect of outcome expectancies was no longer present when mediators were included, and all indirect effects were significant, including the 2-mediator chain (β = .15; P < .05; 95% confidence interval, 0.05-0.32). Truck drivers who expected benefits from dietary change, felt confident about being capable to do so, and formed an intention were likely to report larger amounts of fruit and vegetable intake. Conclusions and Implications: The results suggest that the role of outcome expectancies and self-efficacy are important to consider for understanding and predicting healthy eating intentions in truck drivers.

Binge eating (BE) among female university students is rising in prevalence and few studies have considered the role of social cognitive processes in decisions to engage in BE. This study adopted a theory of planned behavior (TPB) belief-based approach to examine the beliefs that underpin female university students' intentions to BE. Participants (N = 250) completed self-report questionnaires assessing BE intentions and the TPB behavioral (advantages and disadvantages of BE), normative (important others approving/disapproving of BE), and control (barriers toward and motivators for BE) belief measures. For analyses, participants were grouped based on a median split of the overall intention score into those with higher and lower intentions to binge eat. Differences in the TPB beliefs about BE between these two groups were then assessed. Female students with higher intentions to binge eat differed significantly in their endorsement of the likely beliefs related to BE, compared to female students with lower intentions to binge eat. The results suggest that interventions to decrease BE in the female student population should reduce the associated advantages (e.g., stress relief and feelings of comfort), enhance perceptions of disapproval for BE from important others (e.g., partner and friends), provide education about the health implications to strengthen the perceived barriers discouraging BE, and suggest healthy alternatives to overcome the factors (e.g., being alone and boredom) motivating BE.

Objectives To address the scarcity of comprehensive, theory-based research in the Australian context, this study, using a theory of planned behaviour ( TPB) framework, investigated the role of personal and social norms to identify the key predictors of adult Australians' sun-safe intentions and behaviour. Design The study used a prospective design with two waves of data collection, 1 week apart. Methods Participants were 816 adults (48.2% men) aged between 18 and 88 years recruited from urban, regional, and rural areas of Australia. At baseline, participants completed a questionnaire assessing the standard TPB predictors (attitude, subjective norm, and perceived behavioural control [PBC]), past behaviour, behavioural intention, and additional measures of group norm for the referent groups of friends and family, image norm, personal norm, personal choice/responsibility, and Australian identity. Seventy-one per cent of the participants ( n = 577) reported on their sun-safe behaviour in the subsequent week. Results Via path modelling, past behaviour, attitude, group norm (friends), personal norm, and personal choice/responsibility emerged as independent predictors of intentions which, in turn, predicted sun-safe behaviour prospectively. Past behaviour, but not PBC, had direct effects on sun-safe behaviour. The model explained 61.6% and 43.9% of the variance in intention and behaviour, respectively. Conclusions This study provides support for the use of a comprehensive theoretical decision-making model to explain Australian adults' sun-safe intentions and behaviours and identifies viable targets for health-promoting messages in this high-risk context.

The current study investigated key beliefs related to decisions for physical activity (PA) engagement among first-in-family (FIF) students transitioning to university. FIF students ( n = 157) completed an online questionnaire assessing standard theory of planned behaviour constructs and belief-based items. One week later, participants completed a follow-up questionnaire assessing self-reported PA during the previous week. Results identified a range of behavioural, normative, and control beliefs that were significantly correlated with both PA intention and behaviour. Various key beliefs were also identified in relation to FIF students' decisions to be regularly physically active, with behavioural beliefs such as 'take up too much time', normative beliefs including 'friends outside of university', and control beliefs such as 'cost', identified. Finally, frequencies of those who strongly or fully accepted these beliefs were analysed, demonstrating that typically, a large number of FIF students did not hold the beliefs, and as such, these are relevant to target in resultant interventions. The current study effectively highlights a number of key beliefs that can be targeted in programs aimed at encouraging FIF students' PA. Further, the study addresses a gap in the literature of targeting FIF students, a cohort at risk for inactivity, and utilises a sound theoretical framework to identify the unique set of beliefs guiding decisions for PA for this at-risk community group.

Drowning, a largely preventable problem, continues to be a serious issue worldwide, with young men particularly at risk. Alcohol and drugs are often present among young males and, particularly for males aged 18-34 years, alcohol is considered to be a significant risk factor for drowning. The current study aimed to understand the motivations guiding the intentions of young Australian men to engage in drinking and swimming, a behaviour not yet examined systematically. A cross-sectional correlational design was adopted to investigate the ability of the theory of planned behaviour (TPB) and additional variables to predict males' intentions to drink and swim. Males ( N = 211) aged 18-34 years ( Mage = 23.93, SD = 4.01) completed a survey either on-line or paper-based. The survey assessed the TPB constructs of attitude, subjective norm, and perceived behavioural control (PBC); and additional variables of group norms, anticipated regret, objective (i.e. swimming ability) and perceived (i.e. perceived severity and perceived susceptibility) risk perceptions, and past behaviour. Support was found for the TPB constructs of attitude and subjective norm, but not PBC, as well as the additional constructs of group norm, anticipated regret, objective risk, and past behaviour in predicting males' intentions to drink and swim; explaining an overall 76 % of variance. Knowledge gained from this study will help to inform resultant interventions designed to discourage alcohol use in, on, or around water and, thus, prevent drownings in this at risk group.

Given increasing trends of obesity being noted from early in life and that active lifestyles track across time, it is important that children at a very young age be active to combat a foundation of unhealthy behaviours forming. This study investigated, within a theory of planned behaviour (TPB) framework, factors which influence mothers' decisions about their child's (1) adequate physical activity (PA) and (2) limited screen time behaviours. Mothers (N = 162) completed a main questionnaire, via on-line or paper-based administration, which comprised standard TPB items in addition to measures of planning and background demographic variables. One week later, consenting mothers completed a follow-up telephone questionnaire which assessed the decisions they had made regarding their child's PA and screen time behaviours during the previous week. Hierarchical multiple regression analyses revealed support for the predictive model, explaining an overall 73 and 78 % of the variance in mothers' intention and 38 and 53 % of the variance in mothers' decisions to ensure their child engages in adequate PA and limited screen time, respectively. Attitude and subjective norms predicted intention in both target behaviours, as did intentions with behaviour. Contrary to predictions, perceived behavioural control (PBC) in PA behaviour and planning in screen time behaviour were not significant predictors of intention, neither was PBC a predictor of either behaviour. The findings illustrate the various roles that psycho-social factors play in mothers' decisions to ensure their child engages in active lifestyle behaviours which can help to inform future intervention programs aimed at combating very young children's inactivity.

Researchers examined the sun-protective intentions and behavior of young, Caucasian, Australian sportswomen aged between 17 and 35 years (N = 100). The study adopted a 2 x 2 experimental design, comparing group norms (supportive vs. non-supportive) and image norms (tanned vs. pale) related to sun protection and taking into account group identification with friends and peers in the sport. While no significant findings emerged involving image norms, regression analyses revealed a significant two-way interaction for group norm x identification on recreational sportswomen's intentions to engage in sun protection in the next fortnight. Participants identifying strongly with their group had stronger intentions to engage in sun protection when exposed to a norm reflecting fellow recreational sportswomen engaging in sun-protective actions in comparison to those exposed to a non-supportive group. In addition, while prior intentions to engage in sun protection were not significantly related to sun-protection behavior, post-manipulation intentions after exposure to the sun-protective information that was provided were significantly related to follow-up behavior. Overall, the findings supported the importance of group-based social influences, rather than tanned media images, on sun-protective decisions among young recreational sportswomen and provided a targeted source for intervention strategies encouraging sun safety among this at-risk group for repeated sun exposure.

Drawing on an extended Theory of Planned Behaviour (TPB) framework, we employed a cross-sectional design study to investigate psychologists' intentions to integrate complementary and alternative therapies (CAT) into their practice via recommending CAT to clients or referring clients to CAT practitioners. Participants were registered practicing psychologists from a range of therapeutic orientations (e.g., narrative, cognitive behavioural, psychodynamic). The psychologists were either recruited by phone, following a search of the Internet, or were contacted through their place of employment (hospitals, university counselling service). Those who agreed to participate ( N = 122; n = 88 females, n = 34 males) completed a questionnaire that included standard TPB items of attitude, subjective norm, and perceived behavioural control, along with items measuring perceived risk, past behaviour, CAT knowledge, and gender. The outcome variables of interest were (a) intention to recommend CAT to clients and (b) intention to refer clients to CAT practitioners. Structural equation modelling revealed that the extended model was a good fit, explaining 69% (recommending CAT) and 51% (referring to CAT practitioners) of the variance in intentions. For both behaviours, direct paths from attitude and subjective norm to intentions were observed, with perceived risk and past behaviour influencing the TPB predictors of attitudes, subjective norm, and perceived behavioural control. The findings illustrate the role that cognitive and risk factors have on psychologists' decisions to integrate CAT into their practice. Understanding psychologists' cognitions and decisions about CAT integration forms an important basis on which to consider future changes in policy or practice. [ABSTRACT FROM AUTHOR]

We investigated critical beliefs to target in interventions aimed at improving sun-protective behaviours of Australian adults, a population at risk for skin cancer. Participants (N = 816) completed a Theory of Planned Behaviour belief-based questionnaire and a 1-week follow-up of sun-protective behaviour. A range of behavioural, normative and control beliefs correlated with sun-protective behaviour, with no and only minimal differences observed in correlations between beliefs and behaviour by gender and age, respectively. A range of key beliefs made independent contributions to behaviour; however, the behavioural belief about being less likely to tan (β = 0.09); normative belief about friends (β = 0.20); and control beliefs about forgetfulness (β = −0.14), inconvenience (β = −0.17), knowing I will be in the sun for a long time (β = 0.16) and more fashionable sun-protective clothing (β = 0.13) were significant critical beliefs guiding people’s sun-protective behaviour. Our study fills a gap in the literature by investigating an at-risk population for skin cancer and using an established theoretical framework to identify critical beliefs that guide Australian adults’ decisions to sun protect. Attention to these critical beliefs will assist health campaigns and interventions aimed at combating the increasing rates of skin cancer for adults. [ABSTRACT FROM PUBLISHER]

We investigated critical belief-based targets for promoting the introduction of solid foods to infants at six months. First-time mothers (N = 375) completed a Theory of Planned Behaviour belief-based questionnaire and follow-up questionnaire assessing the age the infant was first introduced to solids. Normative beliefs about partner/spouse (β = 0.16) and doctor (β = 0.22), and control beliefs about commercial baby foods available for infants before six months (β = −0.20), predicted introduction of solids at six months. Intervention programs should target these critical beliefs to promote mothers’ adherence to current infant feeding guidelines to introduce solids at around six months. [ABSTRACT FROM PUBLISHER]

Background. Although class attendance is linked to academic performance, questions remain about what determines students' decisions to attend or miss class. Aims. In addition to the constructs of a common decision-making model, the theory of planned behaviour, the present study examined the influence of student role identity and university student (in-group) identification for predicting both the initiation and maintenance of students' attendance at voluntary peer-assisted study sessions in a statistics subject. Sample. University students enrolled in a statistics subject were invited to complete a questionnaire at two time points across the academic semester. A total of 79 university students completed questionnaires at the first data collection point, with 46 students completing the questionnaire at the second data collection point. Method. Twice during the semester, students' attitudes, subjective norm, perceived behavioural control, student role identity, in-group identification, and intention to attend study sessions were assessed via on-line questionnaires. Objective measures of class attendance records for each half-semester (or 'term') were obtained. Results. Across both terms, students' attitudes predicted their attendance intentions, with intentions predicting class attendance. Earlier in the semester, in addition to perceived behavioural control, both student role identity and in-group identification predicted students' attendance intentions, with only role identity influencing intentions later in the semester. Conclusions. These findings highlight the possible chronology that different identity influences have in determining students' initial and maintained attendance at voluntary sessions designed to facilitate their learning.

Objective To identify, using the Theory of Planned Behavior, the sociocognitive factors that influence mothers' decisions toward healthy eating and limiting discretionary choices (eg, lollipops) for their children aged 2–3 years. Design Prospective correlational design with a 1-week follow-up. Participants A total of 197 mothers completed the main survey; 161 completed the follow-up behavior measure. Variables Measured Phase 1 assessed intention, attitude, subjective norm, and perceived behavioral control; and 2 additional variables of parental role construction and group norms. Phase 2 assessed follow-up behavior. Analysis Hierarchical multiple regressions (changes in multivariate coefficient) were used to predict mothers' intentions and actions for the two target behaviors. Results Attitude, subjective norm, and perceived behavioral control predicted intentions; and intentions and perceived behavioral control predicted behavior for healthy eating and discretionary choices. Parental role construction was a significant predictor of intentions for both target behaviors. Conclusions and Implications Results provide support for the application of the Theory of Planned Behavior in this context, as well as the addition of parental role construction. The findings illustrate the potential importance of developing intervention programs that account for sociocognitive factors to modify mothers' child feeding practices that have implications for lifelong health outcomes.

Dual process theories postulate that behaviour is the product of two distinct cognitive systems, the automatic and reflective, and that congruence/divergence between the two types of cognitions can influence the predictive strength of either system on behaviour. However, the congruence/divergence hypothesis has yet to experience strong empirical support. The aim of this study was to test a novel dual process model to determine the moderating effect of affect divergence on the relationship between automatic affective evaluations-affective judgements, and physical activity. A sample of 315 university students recruited from an undergraduate research pool completed the Affective Misattribution Procedure and Affective Exercise Experiences Questionnaire, followed by a measure of physical activity behaviour one week later. A path analysis revealed a significant moderation effect such that the predictive strength of affective judgements was stronger when participants' automatic affective evaluations and affective judgements were congruent. Findings support current dual process theory and contributes to calls for more interventions, such as evaluative conditioning that target automatic processes alongside consciously held beliefs. • Dual process model predicted physical activity, with divergence between automatic-reflective paths moderating each path. • Affect divergence significantly weakened the effect of reflective affect on physical activity. • Past behaviour accounted for the majority of variance in physical activity.
