Taxonomy of moderators that govern explicit memory in individuals with intellectual disability: Integrative research review

This integrative research review aims to discover moderators that influence explicit memory performance of individuals with intellectual disability (ID). We reviewed 47 explicit memory studies (since 1990) that were conducted in populations with ID. We suggest a taxonomy of moderators related to the participants, encoding and retrieval stages, where only an interrelation between the three dictates memory performance. We found that individuals with nonspecific ID can achieve the same level of recognition as individuals with typical development (TD) with the same chronological age when all encoding moderators are favorable. Recognition tests facilitate recollection more than free recall in all etiologies. The performance of individuals with ID was poorer than that of individuals with TD in all auditory memory tasks. Spatial location memory varied with task demands, practice, intention, age and intelligence. We conclude with suggestions for further research and educational implications.     

Does parental mental health moderate the effect of a telephone and internet‐assisted remote parent training for disruptive 4‐year‐old children?

This study explores the moderators affecting the success of an Internet‐based and telephone assisted remote parent training intervention and compares them to an educational control group. We prospectively identified 464 parents who reported at a health check that their 4‐year‐old children showed elevated levels of externalizing behavior. The moderators explored included parental attention deficit and hyperactivity disorder (ADHD) and parental distress. The dependent variables were child externalization scores and self‐reported parenting skills. The measures were completed at baseline, six and 12‐months follow‐up. The 232 families randomized to active treatment received 11 Internet‐based training sessions with weekly phone calls from a coach. The other 232 families had access to a website that provided general positive parenting advice and one 45‐minute phone‐call from a coach. Using hierarchical linear models, we explored if the parental ADHD or parental distress modified the treatment effects on child externalizing behavior or parenting skills. The results showed that none of the independent variables moderated intervention effects on child externalizing behavior or parenting skills. The lack of significant moderator effects could have been due to the treatment's personalization, the format's flexibility and adaptability to when and how the parents wanted to complete the sessions or the relatively low levels of ADHD and parental distress among the participants.
