Violent crime, sociopathy and love deprivation among adolescent delinquents

Ever since Wechsler observed that the adolescent sociopath characteristically scored higher on the performance section of the Wechsler IQ scale relative to the verbal section, psychologists have been debating its meaning. This study examines the relationships between P-V discrepancy scores, love deprivation, and juvenile delinquency among a sample of juvenile probationers. P greater than V scores were significantly related to love deprivation and violent crimes. It was determined that much of the explanatory power of P greater than V with regard to violent delinquent behavior was mediated by love deprivation. We also found that P greater than V scores could not be explained away by social class, low verbal scores, or lower full-scale scores. Only love deprivation was found to be significantly related to P greater than V scores in our path model, thus offering some support to the assertions of some authors that early emotional stresses affect subsequent autonomic nervous system function.     

Predicting change in adolescent adjustment from change in marital problems

The present prospective, longitudinal study of 451 adolescents and their parents extends earlier research by investigating whether change in marital problems predicts change in adolescent adjustment, after controlling for other marital problems and socioeconomic status. Latent growth curves over a period of 5 years were used, and the results revealed that in general, increases or decreases in marital distress and conflict predicted corresponding increases or decreases in adolescent adjustment problems over time. In addition, the analyses suggested that increases in marital distress are as harmful for adolescent adjustment as increases in marital conflict.     

Worry about health in smoking behaviour change

Many smokers and ex-smokers worry about their health. Given that worry keeps attention focused on the threat, it was expected that worrying about health in smokers would motivate them to quit and in ex-smokers may prevent relapse. Furthermore, worry was expected to influence the process of smoking cessation in interaction with self-efficacy, which is a measure of control over smoking, and with disengagement beliefs, which distorts the threatening meaning of potential motivating information. In the present study 380 smokers and 324 ex-smokers were recruited to join a prospective study with a follow-up of eight months. At T1, smoking/quitting behavior, worry and the other psychological constructs were assessed. At T2 quitting activity in smokers and relapse in ex-smokers were assessed. As expected, smokers who worried about the health effects of smoking reported higher quitting activity at T2. The three-way interactions between worry, self-efficacy and disengagement beliefs in the prospective prediction of quitting activity and relapse were significant: Among smokers with high self-efficacy combined with strong disengagement beliefs, worry led to more quitting activity. Among ex-smokers with low self-efficacy combined with strong disengagement beliefs, worry led to more relapse. The present results suggest new ways of approaching the stimulation of quitting and the prevention of relapse.     

Ethical issues in research on adolescent depression and suicidal behaviour

The codes of ethical conduct of the Australian Psychological Society and the American Psychological Association imply that researchers of adolescent depression and suicidal behaviour must plan to intervene to assess risk where a participant in a study indicates an intention to commit suicide. Participants in research of this kind need to be advised of this possibility in advance. The obligation to intervene, and to advise of the possibility of intervention, pose practical and methodological problems for research in this area but do not, it is argued, absolve the researcher of the primary responsibility to contribute to the welfare of the research participant.     

Mechanisms of change in adolescent life satisfaction: A longitudinal analysis

This study explored the psychosocial mechanisms of change associated with differences in levels and linear change of adolescents' global life satisfaction across a 2-year time period. Based on a theoretical model proposed by Evans (1994), this study tested the relations between selected personality (i.e., extraversion and neuroticism) and environmental (stressful life events) variables and global life satisfaction when mediated by internalizing and externalizing problems. The results suggested support for internalizing problems as a mediator of the relationship of personality and environmental variables with life satisfaction. Pathways mediated by internalizing problems significantly predicted levels and linear change of life satisfaction across a 2-year time span. Furthermore, pathways mediated by externalizing problems significantly predicted the level but not the linear change of life satisfaction. Thus, behavior problems and their antecedents appear to relate significantly to adolescents' perceptions of their quality of life. Implications for adolescent mental health promotion were discussed.     

Developing a self-report method for investigating adolescent road user behaviour

The aim of the present study was to develop a self-report questionnaire to provide a classification of aberrant road user behaviour in adolescent children. An Adolescent Road user Behaviour Questionnaire (ARBQ) was developed, comprising 43 items requiring respondents to rate the frequency with which they engaged in specific examples of road-using behaviour. The questionnaire was completed by 2433 children aged 11–16. Factor analysis showed that responses to the 43 items were best fitted by a three-factor solution. Factor 1 comprised items relating to “unsafe road crossing behaviour”, factor 2 comprised items related to “dangerous playing in the road”, and factor 3 comprised items which as a group were termed “planned protective behaviour”. A revised 21-item ARBQ was produced by selecting the items that loaded most strongly on the three factors. The 21-item instrument had good internal reliability. The effects of demographic variables on ARBQ scale scores were investigated. This study provided a tool that could be used in the future by researchers investigating adolescent road user safety. Possible avenues for future research include applying the ARBQ to the study of adolescents’ road accident involvement, and the study of the psychological variables that predict the ARBQ scales.     

Developmental trajectories of internalising behaviour in the prediction of adolescent depressive symptoms

Using a community‐based Australian birth cohort, groups with distinct longitudinal profiles (trajectories) of internalising behaviour from early childhood through mid‐adolescence were identified for boys and girls from parent ratings. Six internalising trajectories were identified for both genders, comprising stable, decreasing, and increasing pathways. Hierarchical regression models predicted the contribution of internalising trajectories to self‐reported age 17 depressive symptoms for males (n = 557) and females (n = 633), after controlling for the effects of a range of adolescent precursors. Internalising trajectories and adolescent psychosocial factors, each contributed to the prediction of subsequent depressive symptoms, with girls and boys on increasing internalising trajectories and boys on a fluctuating high trajectory particularly at risk. Results suggest that parent ratings can identify coherent internalising behaviour pathways that originate early in life and influence subsequent adjustment.     

Driving locus of control and driving behaviors: Inducing change through driver training

Locus of control perceptions have been used to predict driving safety as a stable, dispositional variable. Based on social learning theory, this study tested whether a defensive driving training program coupled with observer feedback could influence domain-specific locus of control beliefs regarding controllability of accidents and therefore impact driving behaviors. Over a 5-week period, 112 individuals’ driving locus of control and driving behaviors were assessed two times, before and after a defensive driving training program and observer feedback. Drivers experienced significant changes in their driving locus of control perceptions. Specifically, drivers reported significantly lower externality and higher internality after training as compared to before training. The changes in driving locus of control predicted an increase in safe driving behaviors. In addition, pretraining motivation to learn predicted a decrease in externality, whereas pretraining self-efficacy predicted the increase in internality. The results indicate that driving locus of control can be influenced by training and observer feedback, and the changes in driving locus of control can predict change in driving behaviors. Findings of the study point to the potential for organizations to enhance driving safety by influencing drivers’ locus of control perceptions.     

Positive affective processes underlie positive health behaviour change

Positive health behaviours such as physical activity can prevent or reverse many chronic conditions, yet a majority of people fall short of leading a healthy lifestyle. Recent discoveries in affective science point to promising approaches to circumvent barriers to lifestyle change. Here, we present a new theoretical framework that integrates scientific knowledge about positive affect with that on implicit processes. The upward spiral theory of lifestyle change explains how positive affect can facilitate long-term adherence to positive health behaviours. The inner loop of this spiral model identifies nonconscious motives as a central mechanism of behavioural maintenance. Positive affect experienced during health behaviours increases incentive salience for cues associated with those behaviours, which in turn, implicitly guides attention and the everyday decisions to repeat those behaviours. The outer loop represents the evidence-backed claim, based on Fredrickson’s broaden-and-build theory, that positive affect builds a suite of endogenous resources, which may in turn amplify the positive affect experienced during positive health behaviours and strengthen the nonconscious motives. We offer published and preliminary evidence in favour of the theory, contrast it to other dominant theories of health behaviour change, and highlight attendant implications for interventions that merit testing.     

Anxiety and locus of conflict in delinquents

The State-Trait Anxiety Inventory for Children (STAIC) and the Children's Manifest Anxiety Scale (CMAS) were administered to 54 juvenile delinquents (27 males, 27 females). Ratings on locus of conflict were also obtained. The STAIC A-State scale was significantly correlated with internalization but not with externalization or the total maladjustment index. Neither A-Trait nor the anxiety portion of the CMAS was correlated with locus of conflict. All measures of anxiety were significantly correlated with each other. Boys were rated as more internal, external, and maladjusted than girls despite the fact that girls reported more subjectively experienced anxiety.     

Eating behaviour, body image, and self-esteem of adolescent girls in Malaysia

This cross-sectional study was undertaken with 489 secondary school girls, ages 15-17 years, to examine disordered eating behaviours of adolescent girls in Malaysia and to estimate associations with body weight, body-size discrepancy, and self-esteem. Dietary restraint, binge eating, body image, and self-esteem were assessed using the Restrained Eating scale of the Dutch Eating Behaviour Questionnaire, the Binge Scale Questionnaire, the Contour Drawing Rating Scale, and the Rosenberg Self-Esteem Scale, respectively. Pearson correlations estimated associations between variables. There were 3.1% underweight, 9.8% at risk of being overweight, and 8.6% overweight girls. A total of 87.3% were dissatisfied with their own body size. Dietary restraint and binge eating were reported by 36.0% and 35.4%, respectively. Body Mass Index (r = .34, p < .01) and body-size dissatisfaction (r = .24, p < .01) were significantly associated with dietary restraint and binge eating, but self-esteem (r = -.20, p < .001) was significantly associated only with binge eating.     

Stability and change in adolescent spirituality/religiosity: a person-centered approach

Although there has been a substantial increase over the past decade in studies that have examined the psychosocial correlates of spirituality/religiosity in adolescence, very little is known about spirituality/religiosity as a domain of development in its own right. To address this limitation, the authors identified configurations of multiple dimensions of spirituality/religiosity across 2 time points with an empirical classification procedure (cluster analysis) and assessed development in these configurations at the sample and individual level. Participants included 756 predominately Canadian-born adolescents (53% female, 47% male) from southern Ontario, Canada, who completed a survey in Grade 11 (M age = 16.41 years) and Grade 12 (M age = 17.36 years). Measures included religious activity involvement, enjoyment of religious activities, the Spiritual Transcendence Index, wondering about spiritual issues, frequency of prayer, and frequency of meditation. Sample-level development (structural stability and change) was assessed by examining whether the structural configurations of the clusters were consistent over time. Individual-level development was assessed by examining intraindividual stability and change in cluster membership over time. Results revealed that a five cluster-solution was optimal at both grades. Clusters were identified as aspiritual/irreligious, disconnected wonderers, high institutional and personal, primarily personal, and meditators. With the exception of the high institutional and personal cluster, the cluster structures were stable over time. There also was significant intraindividual stability in all clusters over time; however, a significant proportion of individuals classified as high institutional and personal in Grade 11 moved into the primarily personal cluster in Grade 12.     

Sun protective behaviour,optimism bias,and the transtheoretical model of behaviour change

This study investigated the relationship between sun protective behaviours and three psychological variables influencing health behaviour: decisional balance, optimism bias, and the transtheoretical model of behaviour change. Two hundred participants completed the ‘Readiness to Alter Sun Protective Behaviour’ questionnaire, and a short questionnaire investigating optimism bias, decisional balance, attitudes, and experiences of sun protection and skin cancer. Participants were evenly distributed between the precontemplation, contemplation, and action stages. Participants in the action stage were significantly more likely to endorse the perceived advantages associated with sun protective behaviour than participants in the precontemplation and contemplation stages. They also reported sunbathing significantly less—and being more concerned about contracting skin cancer—than participants in the earlier stages. Decisional balance and optimism bias scores varied systematically across the stages of change; however, decisional balance was the only significant psychological predictor of sun protective behaviours. Optimism bias was greatest in the precontemplation stage, whereas the action stage was characterised by more positive attitudes to sun protection. This suggests that knowledge of the real risks of skin cancer might be a precursor to behaviour change, but only a change in attitudes results in a move to the action stage and measurable behaviour change.
