Measuring Psychological Inflexibility in Children and Adolescents: Evaluating the Avoidance and Fusion Questionnaire for Youth.

The Avoidance and Fusion Questionnaire for Youth (AFQ-Y8) was developed to measure psychological inflexibility. Although the questionnaire is a well-known tool in clinical practice, its psychometric properties have not been widely investigated in the target population of children and adolescents. The purpose of this study was to investigate the factor structure and validity of the AFQ-Y8 ( = 1,572, mean age 15.

Profiling children's emotion regulation behaviours.

Callear, Harvey, and Bimler (2016, International Journal of Behavioral Development, 41, 456) organized children's emotion regulation behaviours into a coherent structure. However, further investigation is needed to identify core patterns of these emotion regulation behaviours. To identify clusters and prototypal constellations of emotion regulation behaviours, the 85 behavioural items comprising the Children's Emotion Regulation Inventory (ChERI) were ranked by 151 parents in order of applicability, using an ordinal sorting procedure (Method of Successive Sorts).

Updating a meta-analysis of intervention research with challenging behaviour: treatment validity and standards of practice.

Background: This meta-analysis of interventions with challenging behaviour in children with disabilities updates a comprehensive meta-analysis that previously addressed reported standards of practice and effectiveness of different strategies.

Method: Four effect-size algorithms were calculated for published intervention cases, and results analysed and compared to previous findings by behaviour target, intervention type, and other factors.

Results: The evidence largely supports intervention effectiveness, with some inconsistency reflecting the fact that the four metrics assess different aspects of change.
