Testing theories through evaluation research: conceptual and methodological issues embedded in evaluations of parenting programmes

Obviously, evaluations of parenting programmes are important for improving clinical practice. Such evaluation studies can show us whether a parenting programme works and for whom and under which circumstances the programme has the best effects. An additional, often neglected, role of evaluation studies is to provide a test of the theory on which the programme is based. In the present paper, we discuss the ways in which evaluation studies can be used to test and refine theories pertaining to parenting behaviour and child development. Several examples of such studies are presented and both conceptual (specifying the theory-based expectations regarding working mechanisms) and methodological issues (quality criteria for real-life evaluation studies of parenting programmes) involved in evaluation research are addressed.

Parenting and the parent-child relationship in families of children with mild to borderline intellectual disabilities and externalizing behavior

This cross-sectional study examined the association between parenting behavior, the parent-child relationship, and externalizing child behavior in families of children with mild to borderline intellectual disabilities (MBID). The families of a child with MBID and accompanying externalizing behavior problems (n=113) reported more positive discipline and physical punishment but less involvement, less positive parenting, less monitoring, a lower sense of parenting competence, less acceptance of the child, and less closeness to the child than the families of a child with MBID and no accompanying externalizing behavior problems (n=71). The parent-child relationship was most strongly associated with externalizing child behavior, over and above parenting behaviors. In addition, the parent-child relationship was found to be associated with parenting behavior, over and above the childs externalizing behavior. Our results highlight the importance of both the parent-child relationship and parenting behavior in connection with the occurrence of externalizing behavior problems on the part of children with MBID. Parenting behavior and the parent-child relationship may thus be promising targets for interventions with this group of children.

Executive functions and processing speed in children with mild to borderline intellectual disabilities and externalizing behavior problems

ABSTRACT Several studies suggest impaired executive functions (EFs) in children with externalizing behavior problems and average intelligence (e.g., IQ > 85). Even though children with mild to borderline intellectual disabilities (MBID) are at higher risk of developing externalizing behavior problems compared to children with average intelligence, it is not yet clear if impaired EFs are also associated with the occurrence of externalizing behavior problems in children with MBID. In the current study, we therefore assessed three EF components (inhibition, cognitive flexibility, and working memory) as well as processing speed in children with MBID and externalizing behavior problems (n = 71) versus children with MBID with no such problems (n = 70). This was accomplished using a well-established computerized test battery. Even after IQ was controlled for, the children with MBID and externalizing behavior problems showed more impaired working memory performance. Differences for inhibition performance and processing speed were also found but less consistent across the tasks used to measure these aspects of EF. Cognitive flexibility was not more impaired in children with both MBID and externalizing behavior problems relative to children with MBID only. Our findings highlight working memory as a potential target to enhance the treatment of children with MBID and externalizing behavior problems.
