Psychometric properties of the Stress Control Mindset Measure in University students from Australia and the UK.
Introduction: Beliefs about the consequences of stress, stress mindsets, are associated with health and performance outcomes under stress. This article reports the development and examination of the psychometric properties of a measure of stress mindset: The Stress Control Mindset Measure (SCMM). The measure is consistent with theory on mindsets about self-attributes and conceptualizes stress mindset as the extent to which individuals endorse beliefs that stress can be enhancing. Methods: The study adopted a correlational cross-sectional survey design in two student samples. Undergraduate students from an Australian university (Sample 1, N=218) and a UK university (Sample 2, N=214) completed the SCMM and measures of health and well being outcomes. Results: Confirmatory factor analyses supported a four-factor structure and strict measurement invariance across samples(ΔCFI <.01). Reliability, convergent validity, discriminant validity, and concurrent validity of the overall SCMM was supported in both samples. Incremental validity was supported for most outcomes, accounting for significantly more variance (between 2.2% and 5.9%) in health and wellbeing outcomes than an existing measure. Conclusions: Current data provide preliminary support for the SCMM as a reliable and valid measure with good psychometric properties and theoretically consistent relations with health outcomes under stress. Findings provide initial evidence supporting the potential utility of the SCMM in future research examining relations between stress mindsets and health and performance outcomes
Maternal Alcohol Consumption During Pregnancy and Physical Outcomes up to 5 Years of Age: A Longitudinal Study
Aim To examine whether alcohol exposure in pregnancy affects weight and head circumference (HC) at birth and 5 years, and whether these effects are independent of cigarette exposure in pregnancy and social disadvantage. Study design The Mater-University Study of Pregnancy (MUSP) involves a prospective cohort of 8556 mothers who were enrolled at first antenatal visit. The quantity and frequency of alcohol consumption in early and late pregnancy and a measure of binge drinking in early pregnancy were recorded. Weight and HC were measured on children seen at birth and at 5 years. Level of cigarette use in early pregnancy and maternal age and level of education and family income were also measured. Results Light and moderate alcohol consumption in early or later pregnancy had no independent effects on weight or HC at birth or 5 years. Binge drinking in early pregnancy was not associated with restricted HC, and there was no effect modification by concurrent cigarette use in early pregnancy. An apparent effect of alcohol in late pregnancy on birth weight was due to confounding by cigarette use, with social risk being an independent predictor. Conclusion Alcohol ingestion up to moderate levels in pregnancy was not associated with deficits in either weight or HC at birth or at 5 years
Is smoking in pregnancy an independent predictor of academic difficulties at 14 years of age? A birth cohort study
Background. Studies of the effects of maternal smoking during pregnancy have reported inconsistent findings in relation to measures of offspring cognitive functioning Few studies, however, have examined learning outcomes in adolescents, as opposed to I

The Influence of University Students' Stress Mindsets on Health and Performance Outcomes.
BackgroundEmerging evidence indicates that holding particular stress mindsets has favorable implications for peoples' health and performance under stress.PurposeThe aim of the current study was to examine the processes by which implicit and explicit stress mindsets relate to health- and performance-related outcomes. Specifically, we propose a stress beliefs model in which somatic responses to stress and coping behaviors mediate the effect of stress mindsets on outcomes.MethodsUndergraduate university students (N = 218, n = 144 females) aged 17- 25 years completed measures of stress mindset, physical and psychological wellbeing, perceived stress, perceived somatic responses to stress, proactive behaviors under stress, and an implicit association test assessing an implicit stress mindset. At the end of the semester, students' academic performance was collected from university records.ResultsPath analysis indicated significant indirect effects of stress mindset on psychological wellbeing and perceived stress through proactive coping behaviors and perceived somatic symptoms. Stress mindset directly predicted perceived stress and physical wellbeing, and physical wellbeing and academic performance were predicted by stress mindset through perceived somatic symptoms. Implicit stress mindset did not predict proactive behavior as anticipated.ConclusionsCurrent findings indicate that behaviors with the goal of proactively meeting demands under stress and perceived somatic symptoms are important mediators of the effect of stress mindset on health- and performance-related outcomes. The findings from this study provide formative data that can inform the development of future interventions aiming to encourage more adaptive responses to stress
Models of alcohol use by young adults: An examination of various attitude-behavior theories
Objective: The aim of this study was to test the effectiveness of various attitude-behavior theories in explaining alcohol use among young adults. The theory of reasoned action (TRA), the theory of planned behavior and an extension of the TRA that incorporates past behavior were compared by the method of maximum-likelihood estimation, as implemented in LISREL for Windows 8.12. Method: Respondents consisted of 122 university students (82 female) who were questioned about their attitudes, subjective norms, perceived behavioral control, past behavior and intentions relating to drinking behavior. Students received course credit for their participation in the research. Results: Overall, the results suggest that the extension of the theory of reasoned action which incorporates past behavior provides the best fit to the data. For these young adults, their intentions to drink alcohol were predicted by their past behavior as well as their perceptions of what important others think they should do (subjective norm). Conclusions: The main conclusions drawn from the research concern the importance of focusing on normative influences and past behavior in explaining young adult alcohol use. Issues regarding the relative merit of various alternative models and the need for greater clarity in the measure of attitudes are also discussed
Does maternal smoking during pregnancy predict the smoking patterns of young adult offspring? A birth cohort study
OBJECTIVE: To examine the association between maternal smoking during pregnancy and the development of smoking behaviour patterns among young adult offspring. METHOD: Data were from the Mater-University of Queensland Study of Pregnancy (MUSP), a birth cohort of 7223 mothers and children enrolled in Brisbane, Australia, in 1981. The development of smoking behaviours (early or late onset, or combination of onset and prevalence patterns) among offspring at age 21 years with different patterns of maternal smoking (never smoked, smoked before or after pregnancy but not during pregnancy, or smoked during pregnancy) were compared. Maternal smoking information was derived from the prospectively collected data from the beginning of pregnancy until the child was 14 years of age. Analyses were restricted to the 3058 mothers and children whose smoking status was reported. RESULTS: The proportion of young adults who smoked regularly, either with early onset or late onset, was greater among those whose mothers had smoked during pregnancy compared with those whose mothers had never smoked. The smoking patterns among those adolescent offspring whose mothers stopped smoking during pregnancy, but who then smoked at other times during the child's life, were similar to those whose mothers had never smoked. This association was robust to adjustment for a variety of potential covariates. CONCLUSIONS: The findings provide some evidence for a direct effect of maternal smoking in utero on the development of smoking behaviour patterns of offspring and provide yet another incentive to persuade pregnant women not to smoke

The link between sleep problems in infancy and early childhood and attention problems at 5 and 14 years: Evidence from a birth cohort study
Background: Little research has examined the associations between early sleep problems and attention problems over several developmental periods. Aims: To examine whether sleep problems in infancy and early childhood are independently related to attention difficulty at 5 and 14. years, and to the continuity of attention difficulties from 5 to 14. years. Study design: The study was a prospective, population-based birth cohort study. Subjects: 7223 women who delivered a live, singleton child between 1981 and 1983 were recruited at the first antenatal visit. Of these, 4204 had complete information on all key measures. Outcome measures: Attention problems were assessed with items from the Child Behaviour Checklist (CBCL) and were classified as adolescent onset (i.e. problems at 14 but not at 5); early remitter (problems at 5, no problem at 14); and persistent (i.e. at both 5 and 14). Results: At 6. months, sleep problems 'sometimes' were associated with the early remitter group in boys. For sleep problems between 2 and 4. years of age, findings were generally similar for boys and girls with strong associations with adolescent attention. Sleep problems 'often' were independently associated with early remitter and persistent attention problems, and 'sometimes' with early remitter and adolescent onset attention problems. Conclusions: Sleep problems in early childhood are an indicator of subsequent attention problems that may persist into adolescence. Whether these associations are causal requires further research, however their presence provides an opportunity for early intervention and monitoring. © 2010
