This study tested five proposed models of the relationship of negative affect and peer factors in early adolescent body dissatisfaction, dieting, and bulimic behaviors. A large community sample of girls in early adolescence was assessed via questionnaire (X[overbar] age = 12.3 years). Structural equation modeling (SEM) indicated that negative affect mediated the relationship between body dissatisfaction and bulimic behaviors. Body dissatisfaction also contributed independently to the concurrent prediction of bulimic behaviors. The proposed pathways from dieting to negative affect and dieting to bulimic behaviors were not supported. However, perceived peer influence, perceived weight-related teasing, and the self-reported eating behaviors of friendship clique members all contributed significantly to the concurrent prediction of individual eating pathology. These findings highlight the importance of negative affect and both perceived and actual peer attitudes and behaviors in early adolescent eating pathology. (Contains 1 note, 1 table, and 2 figures.)

We examined the factor structure of parental sensitivity to infants as assessed by the Mini‐Maternal Behavior Q‐Sort (Mini‐MBQS), a 25‐item short‐form of the original 90‐item MBQS. We aimed to: (1) identify latent factors of the Mini‐MBQS; and (2) validate each factor by testing associations with infant attachment classifications. Data on parent‐infant dyads (n = 313; 222 mothers with 281 children, 29 fathers with 32 children) were drawn from a three‐generation Australian cohort study. Exploratory Factor Analysis and Exploratory Structural Equation Modelling examined the structure of the Mini‐MBQS. Two latent Mini‐MBQS factors were identified, requiring 8 of 25 original items: (1) Attention and Responsiveness and (2) Contingency in Interactions. Infants with insecure attachment classifications had parents with lower sensitivity across both factors relative to infants classified secure. In particular, infants with resistant attachment classifications had parents with notably low Contingency in Interactions scores. Infants with disorganised attachment classifications had parents with the lowest relative sensitivity across both factors, and in these dyads Attention and Responsiveness scores were especially low. Results provide an empirically derived factor structure for the Mini‐MBQS. Two subscales, each with significant infant attachment associations, may improve precision in clinical intervention and research translation. [ABSTRACT FROM AUTHOR]

The purpose of this study was to systematically review the empirical literature on maternal bonding and associations with infant physical, psychological, and social development. Nineteen articles met inclusion criteria and were included in a qualitative synthesis (79 effect sizes); 15 articles were suitable for aggregation in a series of 14 meta‐analyses (51 effect sizes). All mean effects were in the expected direction, with higher maternal bonding contributing to infant developmental outcomes, including higher attachment quality (r =.35) and parent‐reported lower colic rating (r =.22), easier temperament (r =.19), and positive infant mood (r =.27). Consistent with theoretical explanatory models, the review provides support for the hypothesis that maternal bonding plays a role in fostering more optimal infant development. The review also identifies a paucity of empirical work on this topic and provides directions for future research. [ABSTRACT FROM AUTHOR]

Abstract: Background and Aims: Studies have linked adolescent alcohol use with adverse consequences in adulthood, yet it is unclear how strong the associations are and to what extent they may be due to confounding. Our aim was to estimate the strength of association between different patterns of adolescent drinking and longer‐term psychosocial harms taking into account individual, family and peer factors. Design: Participant‐level data were integrated from four long‐running longitudinal studies: Australian Temperament Project, Christchurch Health and Development Study, Mater Hospital and University of Queensland Study of Pregnancy and Victorian Adolescent Health Cohort Study. Setting: Australia and New Zealand. Participants: Participants were assessed on multiple occasions between ages 13 and 30 years (from 1991 to 2012). Number of participants varied (up to n = 9453) by analysis. Measurements: Three patterns of alcohol use (frequent, heavy episodic and problem drinking) were assessed prior to age 17. Thirty outcomes were assessed to age 30 spanning substance use and related problems, antisocial behaviour, sexual risk‐taking, accidents, socio‐economic functioning, mental health and partner relationships. Findings: After covariate adjustment, weekly drinking prior to age 17 was associated with a two‐ to threefold increase in the odds of binge drinking [odds ratio (OR) = 2.14; 95% confidence interval (CI) = 1.57–2.90], drink driving (OR = 2.78; 95% CI = 1.84–4.19), alcohol‐related problems (OR = 3.04; 95% CI = 1.90–4.84) and alcohol dependence (OR = 3.30; 95% CI = 1.69–6.47) in adulthood. Frequency of drinking accounted for a greater proportion of the rate of most adverse outcomes than the other measures of alcohol use. Associations between frequent, heavy episodic and problem drinking in adolescence and most non‐alcohol outcomes were largely explained by shared risk factors for adolescent alcohol use and poor psychosocial functioning. Conclusions: Frequency of adolescent drinking predicts substance use problems in adulthood as much as, and possibly more than, heavy episodic and problem drinking independent of individual, family and peer predictors of those outcomes.

The article explores the use of data harmonization in mental health research. It reflects on the outcome of the Cannabis Cohorts Research Consortium, a research effort that uses integrated data analysis across multiple Australasian cohorts. Also discussed are the advantages and challenges of data harmonization, including access to high-quality longitudinal studies.

Background: Maternal mental health during pregnancy and postpartum predicts later emotional and behavioural problems in children. Even though most perinatal mental health problems begin before pregnancy, the consequences of preconception maternal mental health for children's early emotional development have not been prospectively studied., Methods: We used data from two prospective Australian intergenerational cohorts, with 756 women assessed repeatedly for mental health problems before pregnancy between age 13 and 29 years, and during pregnancy and at 1 year postpartum for 1231 subsequent pregnancies. Offspring infant emotional reactivity, an early indicator of differential sensitivity denoting increased risk of emotional problems under adversity, was assessed at 1 year postpartum., Results: Thirty-seven percent of infants born to mothers with persistent preconception mental health problems were categorised as high in emotional reactivity, compared to 23% born to mothers without preconception history (adjusted OR 2.1, 95% CI 1.4-3.1). Ante- and postnatal maternal depressive symptoms were similarly associated with infant emotional reactivity, but these perinatal associations reduced somewhat after adjustment for prior exposure. Causal mediation analysis further showed that 88% of the preconception risk was a direct effect, not mediated by perinatal exposure., Conclusions: Maternal preconception mental health problems predict infant emotional reactivity, independently of maternal perinatal mental health; while associations between perinatal depressive symptoms and infant reactivity are partially explained by prior exposure. Findings suggest that processes shaping early vulnerability for later mental disorders arise well before conception. There is an emerging case for expanding developmental theories and trialling preventive interventions in the years before pregnancy.
