Description
Family plays an important yet understudied role in the development of psychopathology during childhood, particularly for children at developmental risk. Indeed, much of the research on families has actually concentrated more on risk processes in individual family members or within-family subsystems. In general, important and complex associations have been found among family-related constructs such as marital conflict, parent-child relationships, parental depression, and parenting stress, which have in turn been found to contribute to the emergence of children's behavioral problems. Research has begun to emerge that certain family system constructs, such as cohesion, organization, and control may influence children's development, but this research has been limited by a focus on parent-reports of family functioning, rather than utilizing observational methods. With notable exceptions, there is almost no observational research examining families of children at developmental risk. This study examined the longitudinal relations among family risk and family system constructs, as well as how family systems constructs mediated the relations between family risk and child outcome. Further, the study examined how developmental risk moderated these relations. The sample followed 242 families of children with and without developmental risk across the transition-to-school period. Family risk factors were assessed at 5 years, using parental reports of symptomatology, parenting stress, and marital adjustment, and observational assessments of the parent-child relationship. Family system constructs (cohesion, warmth, conflict, organization, control) were measured at age 6 using structured observations of the entire family playing a board game. Child behavior problems and social competence were assessed at age 7. Results indicated that families of children with developmental delays did not differ from families of typically developing children on the majority of family system attributes. Cohesion and organization mediated the relations between specific family risk factors and social competence for all families. For families of typically developing children only, higher levels of control were associated with more behavior problems and less social competence. These findings underscore the importance of family-level assessment in understanding the development of psychopathology. Important family effects on children's social competence were found, although the pathways among family risk and family systems attributes are complex.

Description
Pediatric obesity is a public health concern due to its elevated prevalence rates and its relation to concurrent and long-term physical and psychosocial consequences. Pediatric obesity has been found to be associated with problem behaviors, albeit with inconsistent findings. The mechanism of this relation is unclear. It is possible that they have a shared etiology. Self-regulation and parenting practices are two factors that have been implicated in the development of problem behaviors and are garnering evidence for their relation with pediatric obesity. The goal of the present study was to examine whether self-regulation (SREC), positive behavior support (PBSEC), and coercive limit-setting (CLSEC) in early childhood are shared etiological factors of pediatric obesity and problem behaviors. Using multinomial logistic regression the likelihood of belonging to four outcome groups (Comorbid, Problem behavior only, Overweight only, and Typically developing) at age 10 based on these factors was assessed. Analyses controlled for intervention group assignment, child gender, child African-American or Bi-racial, child Hispanic, cumulative risk, child body size impression at age 2, and parent body size impression at baseline. In the models examining SREC alone, for every 1 standard deviation increase in SREC, there was a reliable reduction in the odds of the child belonging to the comorbid and problem behavior only groups at age 10, compared to the typically developing group (OR = 0.386, 95% CI [0.237, 0.628], OR = 0.281, 95% CI [0.157, 0.503], respectively). This relation was maintained when SREC was in the same model as PBSEC and CLSEC. PBSEC and CLSEC alone did not impact the likelihood of belonging to any of the outcome groups. A significant interaction was found between SREC and CLSEC, such that at high levels of both SREC and CLSEC the odds of a child belonging to the overweight only group at age 10 increased, compared to the typically developing group. Results highlight CLSEC as a parenting practice that may place a highly regulated child at risk for becoming overweight. Overall, the findings suggest that problem behaviors and pediatric obesity do not have a shared etiology.
