Parental Knowledge and Youth Risky Behavior: A Person Oriented Approach

Most studies isolate the effects of one knowledge-related behavior on youth outcomes. This study explores the relationship between subgroups of mother–youth dyads that use specific combinations of parental knowledge-related behaviors and youth risky behavior. Using a sample of 796 rural 6th graders (53 % female), we assessed mother and youth reports of maternal knowledge, active parent monitoring efforts, youth disclosure, parental supervision, and the amount of parent–youth communication to identify five knowledge latent classes: High-Monitors, Maternal Over-Estimators, Low-Monitors, Communication-Focused, and Supervision-Focused. Delinquency, antisocial peers, and substance use were associated with increased odds of membership in the Supervision-Focused class, relative to the High Monitors. Membership in the Low Monitors and Maternal Over-Estimators classes was associated with unhealthy attitudes towards substances and for Low Monitors, substance use. The discussion focuses on the value of using a person-oriented approach to understand parental knowledge and risky behavior during early adolescence and intervention implications.     

The historical variability of the age-crime relationship

Methodological problems arising in fitting nonlinear regressions to a dataset are identified in context of research on the age-crime relationship. A modified chisquare distribution is fit to the age distribution of the seven Index crimes for the years 1952, 1957, 1962, 1967, 1972, 1977, 1982, and 1988 to assess the historical invariance of the distribution. Problematic features of Britt's (J. Quant. Criminol. 8, 175–187, 1992) analysis of the same data are highlighted.Britt states no rationale for the choice of these two functions, but his statement that his findings provide support for Greenberg's (1991) use of the Poisson gamma density to model individual offending patterns and questions Rowe and co-workers' (1990) use of the lognormal density as an appropriate model of individual violent offending suggests that this earlier work motivated his choice. Actually, this earlier work is not relevant to Britt's project. Greenberg (1991) and Roweet al. (1990) were concerned with the distribution of criminal propensities across individuals of a given age, not with the distribution of prevalence or participation rates across the ages, and changes therein over time.     

Relationship Between Childhood Sexual Abuse Characteristics and Dissociation Among Women in Therapy

This study investigated the relationship between 10 characteristics of childhood sexual abuse and dissociation in adulthood. A structured clinical interview, the Dissociative Experiences Scale, and the Dissociation Subscale of the Symptom Checklist 90 - Revised were administered to 118 women survivors seeking psychotherapy. Separate stepwise multiple regression analyses were conducted for each dissociation scale to determine which abuse characteristics were predictive of dissociation. In both analyses, the same four variables were significantly related to dissociation: age at onset, coercive sexual acts, objectifying sexual acts, and concurrent multiple perpetrators. Implications of findings for future research and clinical practice are explored.     

Age-cohort analysis of arrest rates

Logistic regressions of age-period-cohort models for city arrest rates are estimated with data from seven U.S. cities for the years 1970–1980 to study the dependence of officially designated criminality in select offense categories on age. A sensitivity analysis is carried out to determine how dependent the findings are on details of model specification.
