    A meta-analysis of the relation between hippocampal volume and memory ability in typically developing children and adolescents
    (Wiley, 2022-03-17) Botdorf, Morgan; Canada, Kelsey L.; Riggins, Tracy
    Memory is supported by a network of brain regions, with the hippocampus serving a critical role in this cognitive process. Previous meta-analyses on the association between hippocampal structure and memory have largely focused on adults. Multiple studies have since suggested that hippocampal volume is related to memory performance in children and adolescents; however, the strength and direction of this relation varies across reports, and thus, remains unclear. To further understand this brain–behavior relation, we conducted a meta-analysis to investigate the association between hippocampal volume (assessed as total volume) and memory during typical development. Across 25 studies and 61 memory outcomes with 1357 participants, results showed a small, but significant, positive association between total hippocampal volume and memory performance. Estimates of the variability across studies in the relation between total volume and memory were not explained by differences in memory task type (delayed vs. immediate; relational vs. nonrelational), participant age range, or the method of normalization of hippocampal volumes. Overall, findings suggest that larger total hippocampal volume relates to better memory performance in children and adolescents and that this relation is similar across the memory types and age ranges assessed. To facilitate enhanced generalization across studies in the future, we discuss considerations for the field moving forward.

    Basic Psychometric Properties of the Child Social Functioning Inventory (CSFI)
    (2004-08-04) Ferrell, Courtney; Beidel, Deborah C.; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    To date, interventions for childhood social phobia have examined outcome primarily in terms of symptomatic reduction or efficacy. Although more emphasis is being placed on reporting clinically relevant outcome, few studies have provided a systematic assessment of treatment effectiveness, perhaps due to a lack of an appropriate assessment inventory. The current study presents the initial psychometric characteristics of the Child Social Functioning Inventory (CSFI), a self-report inventory designed to assess social functioning of preadolescent children. The CSFI contains 24 items with a 6-factor structure. The results indicate that the CSFI has good internal consistency and adequate test-retest reliability. In addition, assessment of the construct validity, including concurrent, convergent, and discriminant validity suggest that the CSFI is a valid inventory of social functioning for children ages 10 or above. Implications for assessment and treatment outcome are discussed.
