Depression can be explained by certain behavioural patterns, especially low levels of environmental rewards; it is generally accompanied by infrequent goal-directed behaviour, increased depressed mood, and anhedonia. However, no research has statistically examined the mediating effect of environmental rewards on the relation between goal-directed behaviour and the symptoms of depressed mood or anhedonia. This study sought to determine whether such a mediating effect of environmental rewards is present in cross-sectional study. The participants included 101 patients diagnosed with major depressive disorders. Data were collected through three questionnaires measuring depression and behavioural patterns that maintain depression: the Center for Epidemiologic Studies Depression Scale (CES-D), the Environmental Reward Observation Scale (EROS), and the Behavioral Activation for Depression Scale-Short Form (BADS-SF). Mediation analysis was conducted using depressed mood and anhedonia as dependent variables, environmental rewards as the mediating variable, and goal-directed behaviour as the independent variable. Environmental rewards significantly mediated the relationship between goal-directed behaviour and anhedonia but not that between goal-directed behaviour and depressed mood. No significant relationships were found among depressed mood, goal-directed behaviour and environmental rewards. From these results, we conclude that low levels of environmental rewards accompanied by infrequent goal-directed behaviour can lead to increased anhedonia but not depressed mood., Author(s): Shuntaro Aoki [sup.1] [sup.2] , Satomi Doi [sup.3] , Satoshi Horiuchi [sup.4] , Koki Takagaki [sup.5] , Asaka Kawamura [sup.6] , Reiji Umeno [sup.7] , Masahiko Fujita [sup.8] , [...]

Summary: Presenteeism is the loss of productivity due to a worker's health problems, despite the worker being present at the workplace. Although the association between presenteeism and insomnia complaints is well known, few studies have examined the association between insomnia severity and presenteeism. This study aimed to explore the association between insomnia severity and presenteeism. This study included 1925 participants (1543 males, 379 females, and three of other genders) in total. The mean age of the participants was 49.94 ± 9.82 years. The inclusion criteria were full‐time employment, working 8 hr per day and 5 days per week, and having no night shifts. The insomnia severity was classified based on the Insomnia Severity Index and Athens Insomnia Scale criteria. Logistic regression analysis showed that moderate and severe insomnia severity were associated to a greater magnitude with presenteeism than mild insomnia severity. Severe insomnia severity was associated to a greater magnitude with presenteeism than moderate insomnia severity. In summary, logistic regression analysis showed that increased insomnia severity based on Insomnia Severity Index classification was associated with increased odds of presenteeism, but increased insomnia severity based on Athens Insomnia Scale classification was not fully consistent with increased odds of presenteeism. Because increased insomnia severity is associated with worsening of presenteeism, early detection of and early intervention against insomnia complaints are important for reducing presenteeism. This study was the first to examine the associations between presenteeism and insomnia severity classification of no insomnia, mild, moderate, and severe insomnia severity. [ABSTRACT FROM AUTHOR]

Background: Safety behaviour plays an important role in the maintenance of social anxiety disorder (SAD). SAD patients engage in various safety behaviours in social situations in order to decrease the risk of negative evaluations from others. Aims: The present study examined the effect of safety behaviour on the maintenance of anxiety and negative belief in SAD by using Structural Equation Modelling (SEM). Methods: Participants were a healthy group (442) and a SAD group (46) who met the SAD criteria for DSM-IV and who had high scores of SAD symptoms. In the assumed maintenance model, independence variables were safety and avoidance behaviour and dependence variables were anxiety and negative belief. Results: This result showed that the SAD group significantly has more high scores than the healthy group in all scales of anxiety, negative belief and avoidance behaviour, expect for safety behaviour. The result of the multiple-group procedure indicated that safety behaviour contributes more strongly to anxiety and negative belief in the SAD group than in the healthy group. Conclusions: It is speculated that the SAD group have a stronger link between safety behaviour and negative belief than the healthy group, whereas frequency of the use of safety behaviour is equivalent between two groups. These results support the findings of previous studies. Key words: social anxiety disorder (SAD), safety behaviour, avoidance behaviour, anxiety, negative belief

Hofmann (e), Kyung Ja Oh (f), Yuji Sakano (g) Keywords: Culture; Anxiety; Norms; Behavior; Blushing Abstract: Cultural considerations in social anxiety are a rarely investigated topic although it seems likely that differences between countries in social norms may relate to the extent of social anxiety. The present study investigated individuals' personal and perceived cultural norms and their relation to social anxiety and fear of blushing. A total of 909 participants from eight countries completed vignettes describing social situations and evaluated the social acceptability of the behavior of the main actor both from their own, personal perspective as well as from a cultural viewpoint. Personal and cultural norms showed somewhat different patterns in comparison between types of countries (individualistic/collectivistic). According to reported cultural norms, collectivistic countries were more accepting toward socially reticent and withdrawn behaviors than was the case in individualistic countries. In contrast, there was no difference between individualistic and collectivistic countries on individuals' personal perspectives regarding socially withdrawn behavior. Collectivistic countries also reported greater levels of social anxiety and more fear of blushing than individualistic countries. Significant positive relations occurred between the extent to which attention-avoiding behaviors are accepted in a culture and the level of social anxiety or fear of blushing symptoms. These results provide initial evidence that social anxiety may be related to different cultural norms across countries.

The rapid increase of patients with eating disorders in Japan has made necessary the reliable and valid measurement of psychological factors in eating disorders. The purpose of this study was to examine the reliability and validity of the Japanese version of the Eating Disorder Inventory. 766 females without eating disorders and 139 female patients with eating disorders responded to the Eating Attitude Test and the Eating Disorder Inventory. Principal factor extraction with promax rotation isolated 9 interpretable factors with satisfactory internal consistency (Cronbach alpha range = .74-.90). Compared with controls, patients scored significantly higher on all factors after minimizing the influence of Body Mass Index. There were strong correlations among factor scores and scores on the Eating Attitudes Test, particularly among patients. These results indicate the Eating Disorder Inventory as showing psychometrically sound internal consistency and concurrent validity.

The Italian form of the Adolescent Reinforcement Survey Schedule (ARSS-I) was administered to (N = 648) high school boys and girls from northern and central Italy. Their responses were factor analyzed using a principal component, VARIMAX rotation procedure (SAS Institute, Inc., 1990). The 10 interpretable factors from the Italian data were compared and contrasted to factor analytic results from Holmes (1991, 1994) studies using American and Japanese students. Additionally, the Italian data analyses includes an examination by gender using t tests for each of the ARSS-I items and an ANOVA for age and age-gender effects on responses to the ARSS-I.

Factor-analyzed correlations among items of the Japanese Adolescent Reinforcement Survey Schedule by Japanese high school students (N = 939) and college students (N = 500) were compared to investigate the changes in reinforcers between mid- and late adolescence, gender differences, and the specific groupings of reinforcers which suggest certain interventions for either or both groups of adolescents. The factor analysis yielded ten interpretable factors in both groups. These factors were similar and did not suggest a dramatic shift in reinforcers between mid- and late adolescence. Items related to heterosexual activities and antisocial behaviors were rated as more pleasurable by males and items related to interpersonal relationships and academic activities were rated as more pleasurable by females. Since both groups of students attach high reinforcement value to interpersonal interaction with peers and family members, interventions focusing on social skills development might be popular and well attended.

Substance abusers' family members tend to have a unique dysfunctional cognition, which may affect mental health. Objectives: This study investigated dysfunctional cognition's effects on mental health in a sample of substance abusers' family members. Methods: A survey questionnaire was completed twice to obtain data on mental illness, wellbeing, and dysfunctional cognition. A hierarchical linear regression analysis tested the relationships net of the effects of control variables. Results: Hierarchical regression analysis revealed that dysfunctional cognition affected mental illness, but not wellbeing. Conclusion: Cognitive dysfunction should be incorporated into interventions to support the mental health of substance abusers' family members. [ABSTRACT FROM AUTHOR]
