Intelligence in childhood and risk of psychological distress in adulthood: The 1958 National Child Development Survey and the 1970 British Cohort Study

Lower cognitive ability is a risk factor for some forms of severe psychiatric disorder, but it is unclear whether it influences risk of psychological distress due to anxiety or the milder forms of depression. The participants in the present study were members of two British birth national birth cohorts, the 1958 National Child Development Survey (n = 6369) and the 1970 British Cohort Study (n = 6074). We examined the association between general cognitive ability (intelligence) measured at age 10 (1970 cohort) and 11 years (1958 cohort) and high levels of psychological distress at age 30 (1970 cohort) or 33 years (1958 cohort), defined as a score of 7 or more on the Malaise Inventory. In both cohorts, participants with higher intelligence in childhood had a reduced risk of psychological distress. In sex-adjusted analyses, a standard deviation (15 points) increase in IQ score was associated with a 39% reduction in psychological distress in the 1958 cohort and a 23% reduction in the 1970 cohort [odds ratios (95% confidence intervals) were 0.61 (0.56, 0.68) and 0.77 (0.72, 0.83), respectively]. These associations were only slightly attenuated by further adjustment for potential confounding factors in childhood, including birth weight, parental social class, material circumstances, parental death, separation or divorce, and behaviour problems, and for potential mediating factors in adulthood, educational attainment and current social class. Intelligence in childhood is a risk factor for psychological distress due to anxiety and the milder forms of depression in young adults. Understanding the mechanisms underlying this association may help inform methods of prevention.     

The Mediating Effects of Psychological Contracts on the Relationship Between Human Resource Systems and Role Behaviors: A Multilevel Analysis

Purpose  The purpose of this study was to examine the mediating effect of the psychological contracts on the relationship between human resource (HR) systems and role behavior. Design/Methodology/Approach  Multilevel analyses were conducted on data gathered from 146 knowledge workers and 28 immediate managers in 25 Taiwanese high-tech firms. Findings  Relational psychological contracts mediated the relationship between commitment-based HR systems and in-role behaviors, as well as organizational citizenship behaviors. Transactional psychological contracts did not significantly mediate these relationships. In addition, the results also indicated that commitment-based HR systems related positively to relational psychological contracts and negatively to transactional psychological contracts. Practical Implications  Commitment-based HR systems could elicit a wide range of knowledge workers’ behaviors that are beneficial to the goals of the firms. Furthermore, our findings also provide insight into, how HR systems potentially elicit employees’ role behaviors. Organizations could elicit employees’ in-role behaviors by providing financial and other non-financial, but tangible, inducements and facilitate employees’ extra-role behaviors by providing positive experiences, such as respect, commitment, and support. Originality/Value  The study is one of the primary studies to empirically examine the mediating effect of psychological contracts on HR systems and employee behaviors.

Predictors of Parenting Stress for Abusive and Nonabusive Mothers

We examined a model of parenting stress for abusive mothers (n = 80) and nonabusive mothers (n = 86) using linear regression analyses. Predictors in the model included (a) the degree to which mothers were bothered by child misbehavior, (b) mothers’ general psychological functioning, and (c) observed child behavior during parent–child interactions. Whether abuse status moderated the relations between each predictor and parenting stress was also explored. Results indicated that mothers’ psychological functioning significantly predicted parenting stress; however, neither mothers’ intolerance for their children’s misbehavior nor observed child behavior were significant predictors of parenting stress in the regression model. A test of moderation revealed a significant interaction between parental intolerance and abuse status such that intolerance predicted parenting stress level only for abusive mothers. A comparison of correlations indicated that abusive mothers’ level of parenting stress was more closely related to their intolerance for child conduct problems than to the child’s behavior during play with their mothers. Findings are discussed in terms of implications for interventions to reduce parenting stress experienced by nonabusive and abusive mothers.     

Psychometric Evaluation of the Meaningful Life Measure

The 23-item Meaningful Life Measure (Morgan and Farsides 2008) comprises five subscales, each designed to assess a distinct component of personal meaning: purposeful life; valued life; accomplished life; principled life; and exciting life. In addition to providing a comprehensive composite meaning measure, this instrument presents the possibility of measuring these components separately in future research applications. To demonstrate the utility of their separate measurement, the present study therefore aimed to show differential patterns of correlation between these five subscales and meaning correlates identified in the literature. The MLM’s factor structure and internal reliability were replicated on the present sample. Evidence was then provided for the MLM’s convergent validity, and it was demonstrated that its five subscales were indeed differently predicted by the meaning correlates from the literature. Findings attest to the practical utility of a five-factor conceptualisation of meaning in life. In addition to identifying people who score low and high on different factors of meaning in life, the MLM facilitates the further investigation of specific antecedents and consequences of different meaning components.

Social neuroscience of child and adolescent depression

The social neuroscience of child and adolescent depression is inherently multidisciplinary. Depressive disorders beginning early in life can have serious developmental and functional consequences. Psychopathology research has described depression's defining clinical and contextual features, and intervention research has characterized its response to treatment and prevention programs. Neuroendocrine, electrophysiological, and neuroimaging studies have identified core neurobiological aspects of early-onset mood disorders. These areas are reviewed using a developmental social neuroscience perspective for integrating disparate observations. The paper introduces a dynamic adaptive systems framework, and it discusses hedonic capacity, stress sensitivity, ruminative self-focus, and attentional impairments as fundamental components of mood disorders.     

Incremental Validity of Coping-oriented Marijuana Use Motives in the Prediction of Affect-based Psychological Vulnerability

The present investigation examined whether coping-oriented motives to use marijuana, as measured by the Marijuana Motives Measure (MMM; Simons et al. in J. Couns. Psychol. 45:265–273, 1998), were uniquely related to affect-based psychological vulnerability factors among marijuana users. Participants were 131 adult current marijuana users (72 women, M _age = 20.14, SD = 3.37 years). As hypothesized, after controlling for gender, cigarettes smoked per day, past 30-day marijuana use, total years of marijuana use, and alcohol consumption, coping motives were significantly and incrementally related to negative affect-based psychological vulnerability factors. No other marijuana use motives demonstrated a similar type of relationship to the dependent variables, providing a high degree of explanatory specificity. These data suggest that coping-oriented motives to use marijuana may be an important explanatory construct in better understanding marijuana and psychological vulnerability relations.     

Effects of the School-to-Work Group Method among young people

This study examines effects of the School-to-Work Group Method among 17-25-year-old young people facing the transition from vocational college to work. After baseline measurement (N = 416) participants were randomized into experimental and control groups. The results of ten month follow-up (N = 334) showed notable beneficial impacts of the group method on both employment itself and on how well it matched participants’ education and personal career plans. The group method also had a significant preventive effect on psychological distress and depression symptoms among those initially at risk of suffering from mental disorder. Moreover, it considerably increased participants’ personal work life, finances and property goals.     

Links between parental psychological violence, other family disturbances, and children's adjustment

In a sample of 143 parent-child dyads from two-parent and separated families, this investigation documented the links between parental psychological violence and separation or divorce, severity of parental conflict, triangulation of the child in this conflict, and polarized parent-child alliances. The unique and combined contributions of all these variables to children's behavior problems were also assessed. Participants were parents, mostly mothers, and their 10-12-year-old child. They were recruited through schools, community organizations, and newspapers. Questionnaires were administered at home. Findings suggest that separated families undergo more relational disturbances than two-parent families (more severe conflicts, more triangulation, stronger parent-child alliances), but the amount of parental psychological violence was similar in both groups. Psychological violence was associated with the severity of parental conflict, especially in two-parent families. Triangulation of the child in parental conflict was another correlate of psychological violence. Once all variables were controlled for, psychological violence remained the only significant correlate of children's externalized behavior problems. These findings raise the importance of preventing psychological violence toward children, especially in families plagued with severe parental conflicts.
