Hyperactive and antisocial behaviors: comorbid or two points in the same process?

We hypothesized that hyperactivity defines the first stage and that antisocial problems define a second stage in a progression that leads eventually to early-onset delinquency. As expected, a structural equation model (SEM) showed that a latent construct for hyperactivity was significantly related to a latent construct for antisocial problems. We hypothesized that this path reflected a shared mechanism, disrupted parental discipline. A second SEM showed that the relation between hyperactivity and antisocial behavior really reflected a shared disruption in parental discipline. A third SEM showed that having antisocial parents was uniquely correlated with antisocial children but not with hyperactivity. A fourth SEM showed that early-onset delinquency was predicted by a latent construct for antisocial child; but when this was partialed out, the contribution for hyperactivity was nonsignificant.

Parenting through change: an effective prevention program for single mothers.

This randomized experimental prevention study (a) evaluated the effectiveness of a parent-training program in a sample of 238 divorcing mothers with sons in Grades 1-3 and (b) provided an experimental test of coercion theory. The intervention produced reductions in observed coercive parenting, prevented decay in positive parenting, and generally improved effective parenting practices in comparisons of mothers in experimental and control groups. Moreover, coercion theory was supported. Improved parenting practices correlated significantly with improvements in teacher-reported school adjustment, child-reported maladjustment, and mother-reported maladjustment. The intervention indirectly benefitted child outcomes through improved parenting practices for a model based on child report and, to a lesser extent, on teacher report. The intervention did not produce direct effects on child outcomes.

Determinants of observed confidant support for divorced mothers.

Marital separation can be a time of extreme stress and can significantly disrupt support networks and support processes when they are needed most. The purpose of this investigation was to test mechanisms of support erosion in a multimethod study of 138 divorced mothers and their confidants. Previous work was extended by using observational measures of confidant support in a process model including (a) maternal characteristics over time, (b) support person characteristics, and (c) relationship characteristics (intimacy and confidant relationship type). A hypothesized mechanism of erosion was supported in which ongoing maternal distress was positively associated with levels of confidant negativity, which in turn was related to lower levels of observed support. Having a partner was related to more intimacy than was having family and friends. Contrary to expectation, however, having a partner was related to lower levels of support, and intimacy was not related to observed support.

Parenting of divorced mothers as a link between social status and boys' academic outcomes: unpacking the effects of socioeconomic status.

Socialization theories posit parenting practices as mechanisms linking socioeconomic status (SES) and children's academic outcomes. A mediational parenting model was tested examining separate effects of maternal education, occupation, and income for a sample of 238 divorced or recently separated mothers of 6- to 9-year-old sons. For the SEM path models, each indicator of SES was associated with better parenting, and parenting in turn had indirect effects on achievement through home skill-building activities and school behavior. The direct effect of maternal education on achievement was mediated by home skill-building activities, the direct effect of maternal occupation on achievement was not mediated, and income measures had no direct effects on achievement. These findings underscore the importance of unpacking the effects of SES and the relevance of effective parenting practices as a protective factor in the home and school environment for young boys' school success during postdivorce adjustment.
