The Relationship Between Parenting and Delinquency: A Meta-analysis

This meta-analysis of 161 published and unpublished manuscripts was conducted to determine whether the association between parenting and delinquency exists and what the magnitude of this linkage is. The strongest links were found for parental monitoring, psychological control, and negative aspects of support such as rejection and hostility, accounting for up to 11% of the variance in delinquency. Several effect sizes were moderated by parent and child gender, child age, informant on parenting, and delinquency type, indicating that some parenting behaviors are more important for particular contexts or subsamples. Although both dimensions of warmth and support seem to be important, surprisingly very few studies focused on parenting styles. Furthermore, fewer than 20% of the studies focused on parenting behavior of fathers, despite the fact that the effect of poor support by fathers was larger than poor maternal support, particularly for sons. Implications for theory and parenting are discussed.

Age at natural menopause in a population-based screening cohort: the role of menarche, fecundity, and lifestyle factors

OBJECTIVE To verify whether a population-based hypothesis (age at menarche and age at natural menopause have an inverse relationship) also applies at the level of the individual and to investigate what other factors predict age at natural menopause. DESIGN Prospective cohort study (the Doorlopend Onderzoek Morbiditeit/Mortaliteit [DOM] project). SETTING Prevention Breast Cancer Screening Centre, Utrecht, The Netherlands. PATIENT(S) A cohort of 3,756 Dutch women, born between 1911 and 1925, participating in a population-based breast cancer screening program, who experienced a natural menopause. Three samples of women were studied: a sample who did not use oral contraceptives (OCs) (n = 3,347), a sample of OC users (n = 409), and a combined sample of OC users and nonusers (n = 3,756). MAIN OUTCOME MEASURE(S) Age at menopause and menarche, fertility patterns, OC use, height, weight, smoking, and demographic variables. RESULT(S) No relation was found between age at menarche and age at natural menopause. The total percentage of variance in age at natural menopause explained by multiple regression including all factors was minimal, ranging from 1.3% to 9.7% in OC users. Linear regression analysis indicated a slight secular trend in age at menopause. CONCLUSION(S) Frischs hypothesis could not be corroborated at the individual level. These results suggest that age at menarche and menopause should be treated as independent risk factors for breast cancer. Modification of age at menopause by lifestyle factors (except possibly for OC use) appears minimal.

Trajectories of Delinquency and Parenting Styles

We investigated trajectories of adolescent delinquent development using data from the Pittsburgh Youth Study and examined the extent to which these different trajectories are differentially predicted by childhood parenting styles. Based on self-reported and official delinquency seriousness, covering ages 10–19, we identified five distinct delinquency trajectories differing in both level and change in seriousness over time: a nondelinquent, minor persisting, moderate desisting, serious persisting, and serious desisting trajectory. More serious delinquents tended to more frequently engage in delinquency, and to report a higher proportion of theft. Proportionally, serious persistent delinquents were the most violent of all trajectory groups. Using cluster analysis we identified three parenting styles: authoritative, authoritarian (moderately supportive), and neglectful (punishing). Controlling for demographic characteristics and childhood delinquency, neglectful parenting was more frequent in moderate desisters, serious persisters, and serious desisters, suggesting that parenting styles differentiate non- or minor delinquents from more serious delinquents.

A Meta-analysis of Attachment to Parents and Delinquency

To investigate the link between attachment to parents and delinquency, and the potential moderating effects of age and sex, 74 published and unpublished manuscripts (N = 55,537 participants) were subjected to a multilevel meta-analysis. A mean small to moderate effect size was found (r = 0.18). Poor attachment to parents was significantly linked to delinquency in boys and girls. Stronger effect sizes were found for attachment to mothers than attachment to fathers. In addition, stronger effect sizes were found if the child and the parent had the same sex compared to cross-sex pairs of children and parents. Age of the participants moderated the link between attachment and delinquency: larger effect sizes were found in younger than in older participants. It can be concluded that attachment is associated with juvenile delinquency. Attachment could therefore be a target for intervention to reduce or prevent future delinquent behavior in juveniles.

A meta-analysis on age differences in risky decision making: Adolescents versus children and adults

Despite evident heightened adolescent risk-taking in real-life situations, not all experimental studies demonstrate that adolescents take more risks than children and adults on risky decision-making tasks. In the current 4 independent meta-analyses, neurodevelopmental imbalance models and fuzzy trace theory were used as conceptual frameworks to examine whether adolescents engage in more risk-taking than children and adults and whether early adolescents take more risks than children and mid-late adolescents on behavioral risk-taking tasks. Studies with at least 1 of the aforementioned age comparisons met the inclusion criteria. Consistent with imbalance models and fuzzy trace theory, results from a random-effects model showed that adolescents take more risks (g = .37) than adults, and early adolescents take more risks (g = .15) than mid-late adolescents. However, inconsistent with both perspectives, adolescents and children take equal levels of risk (g = -.00), and early adolescents and children also take equal levels of risk (g = .04). Meta-regression analyses revealed that, consistent with imbalance models, (a) adolescents take more risks than adults on hot tasks with immediate outcome feedback on rewards and losses; however, contrary to imbalance models but consistent with fuzzy trace theory, (b) adolescents take fewer risks than children on tasks with a sure/safe option. Shortcomings related to studies using behavioral risk-taking tasks are discussed. We suggest a hybrid developmental neuroecological model of risk-taking that includes a risk opportunity component to explain why adolescents take more risks than children in the real world but equal levels of risks as children in the laboratory.

Longitudinal changes in the time parents spend in activities with their adolescent children as a function of child age, pubertal status and gender.

This study examined the time Dutch mothers (N = 301) and fathers (N = 255) spend per day engaging in 4 activities (going somewhere, doing something, watching TV, and eating together) with their adolescent children both concurrently and 5 years later. Also assessed was whether parent-child shared time was related to parent or child gender and whether age-related differences could be explained by adolescent pubertal status, family conflict, adolescent and parent work or volunteer hours, parental work stress, and adolescent computer use. Finally, the study examined whether family conflict predicted changes in shared time and whether shared time predicted changes in conflict. The findings showed that age changes depended on the activity and that pubertal status mediated age differences in TV viewing among mixed-gender parent-child pairs. Shared time during pre-, early, and mid-adolescence was linked to decreases in family conflict 5 years later.

The Effects of Pubertal Development on Achievement during Adolescence

The present study investigated the role of pubertal timing and pubertal status on school achievement and achievement orientation among a sample of adolescents followed during sixth, seventh, and eighth grades (early adolescence). Also investigated were the longer-term effects of timing of puberty on achievement-related measures for a subsample of individuals followed up in twelfth grade. Results indicated that during early adolescence late-maturing boys had the lowest school achievement, receiving the lowest grades in language arts, literature, and social studies. Late-maturing girls showed the highest achievement in these domains. Achievement orientation, that is, beliefs about ones ability to achieve, did not explain these results. Very few long-term effects of puberty on the achievement measures were found. The educational implications of these results are discussed.

Long-Term Effects of Family Functioning and Child Characteristics on Problem Drinking in Young Adulthood

Several studies have shown that disturbances in the parent-child relationship in childhood are related to patterns of alcohol abuse in adolescence and young adulthood. Recently some researchers, however, argue that whether poor parenting is detrimental depends on specific child characteristics. Hence, instead of examining overall effects of parenting, it might be more appropriate to search for specific child-environment effects that lead to problematic drinking patterns. In this paper, we investigate the interplay between child characteristics (lack of self-control and aggression) and parenting on problematic alcohol use in young adulthood. Data were used from a longitudinal study that followed 301 children and their parents for a period of 10 years. Both parents and their children were interviewed on parenting practices and child characteristics when the child was a young adolescent (mean age of 12 years at time 1) and extensive information on problematic alcohol use was gathered when the participants were young adults (mean age was 22 at time 3). Findings showed strong effects of childhood aggression (men only) and poor family functioning on enhanced levels of problem drinking in young adulthood. Further, the combination of high levels of aggression and low levels of family functioning were related to problem drinking in men, whereas the combination of low parental control and low levels of affection expression were related to problem drinking in women.

The relation between the absolute level of parenting and differential parental treatment with adolescent siblings’ adjustment

BACKGROUND The present study extends existing studies on the role of differential parental treatment in explaining individual differences in adolescent problem behaviors above the absolute level of parenting and clarifies the function of gender of the child, birth rank and gender constellation of the sibling dyads. METHOD The absolute level of parenting practices and differential treatment were examined in a sample of 288 Dutch families consisting of two parents and two adolescents. Parents reported on adolescent internalizing and externalizing problem behavior and adolescents reported on parental warmth and coercive control. RESULTS Parenting dimensions were related to problem behavior for same- and mixed-gender sibling pairs, with coercive control as the strongest predictor. No direct association was found between differential parental treatment and child outcomes above the absolute levels of parenting in same-gender sibling pairs. However, differential maternal and paternal control was related to internalizing behavior of girls and differential paternal warmth was linked to externalizing behavior of the older siblings in mixed-gender sibling pairs. CONCLUSION Differential parental treatment is uniquely associated with child problem behavior above the absolute level of parenting for girls and early-born children in mixed-gender sibling pairs. Any examination of the effects of differential treatment should not be undertaken without considering the gender and birth rank of the sibling pairs.

The Pubertal Development Scale: A Rural and Suburban Comparison

The Pubertal Development Scale (PDS) is a noninvasive measure of pubertal development. The purpose of this study was to compare means and standard deviations on the PDS across samples of seventh graders from rural Iowa and suburban Chicago who were matched on gender, age, race, and grade in school. Matched samples of boys each comprised 50 subjects; those of girls each comprised 52 subjects. Results of MANOVAs showed that rural Iowa girls were more advanced on the five markers of pubertal development than were suburban Chicago girls. Rural Iowa boys were more advanced than their counterparts in the suburban Chicago sample on four of the five markers. Psychometric analysis of the five-item scale suggested adequate internal consistency for boys and girls (.66 to .81). The predictive validity of the PDS was satisfactory. Possible reasons for differences in rates of development are discussed.
