Attention and executive functions in adolescents with spina bifida.

OBJECTIVE: This study was designed to examine attention processes and executive functioning in adolescents with spina bifida, and to explore whether impairment in these domains contributes to problems with social adjustment. METHODS: A sample of adolescents with spina bifida (n = 68) and a matched comparison group (n = 68) and their families were followed longitudinally. All participants completed questionnaires, and the adolescent participants underwent neurocognitive testing. RESULTS: The spina bifida sample showed greater impairment on objective and subjective measures of attention and executive functioning, even when differences in intellectual functioning were controlled. Additionally, attention and executive deficits were found to be predictive of social adjustment difficulties. A mediational analysis suggested the neurocognitive deficits mediate associations between spina bifida status and social adjustment difficulties. CONCLUSIONS: Adolescents with spina bifida appear to exhibit clear impairment in attention and executive functioning and this impairment may contribute to their well-established social difficulties.

Predictors of parenting behavior trajectories among families of young adolescents with and without spina bifida.

OBJECTIVE: To evaluate the utility of familial and parental variables in predicting trajectories of parenting behaviors among families of young adolescents with and without spina bifida (SB). METHOD: Sixty-eight families with a child with SB and a demographically matched comparison group (CG) of 68 families of an able-bodied child participated. Observational and questionnaire assessments of parenting behavior were collected via home visits at three time points, as were reports of parent and family functioning. RESULTS: Family conflict was negatively associated with adaptive parenting behavior at Time 1 (T1), but positively associated with adaptive parenting change. Although the direction of this effect was the same across both groups, findings were more robust for the SB sample. Among fathers of children with SB, parenting stress was positively associated with adaptive parenting at T1 but negatively associated with adaptive parenting change. In contrast, within the CG, paternal parenting stress was negatively associated with adaptive parenting at T1 but showed no enduring negative effects in longitudinal analyses. CONCLUSIONS: Family conflict and parenting stress were significant predictors of parenting behaviors and longitudinal parenting change. Findings are interpreted within a developmental context such that variables associated with maladaptive (or adaptive) parenting in the short run, may facilitate adaptive (or maladaptive) parenting over time based on young adolescents' changing developmental needs.

Mediator and moderator effects in developmental and behavioral pediatric research.

The terms mediation and moderation are defined and clarified with particular emphasis on the role of mediational and moderational analyses in developmental and behavioral pediatric research. The article highlights the applicability of mediational and moderational analyses to longitudinal, intervention, and risk and protective factor research, and it provides basic information about how these analyses might be conducted. Also included is a discussion of various ways that both mediator and moderator variables can be incorporated into a single model. The article concludes with extended examples of both types of analyses using a longitudinal pediatric study for illustration. The article provides recommendations for applying mediational and moderational research in clinical practice.

Observed and perceived parental overprotection in relation to psychosocial adjustment in preadolescents with a physical disability: the mediational role of behavioral autonomy.

The purpose of this study was to tes a mediational model of associations between parental overprotectiveness (OP), behavioral autonomy. and psychosocial adjustment in 68 families with 8- and 9-year-old preadolescents with spipa bifida and a demographically matched sample of 68 families with able-bodied children. Measures included questionnaire and observational assessments of parental OP; parent and child reports of behavioral autonomy; and parent, child, and teacher reports of preadolescent adjustment. On the basis of both questionnaire and observational measures of OP, mothers and fathers of children with spina bifida were significantly more overprotective than their counterparts in the able-bodied sample, although this group difference was partially mediated by children's cognitive ability. Across samples, mothers were more likely to be overprotective than fathers. Both questionnaire and observational measures of parental OP were associated with lower levels of preadolescent decision-making autonomy as well as with parents being less willing to grant autonomy to their offspring in the future. For the questionnaire measure of OP, and only for the spina bifida sample. the mediational model was supported such that parental OP was associated with less behavioral autonomy, which was, in turn, associated with more externalizing problems. Findings are discussed in relation to the literature on parenting, autonomy development, and pediatric psychology.
