Development and Validation of the Interpersonal Affect Improvement Strategies Questionnaire

This research outlines the development and validation of a new self-report measure to assess the tendency to use different interpersonal affect improvement strategies within the normal adult population (Interpersonal Affect Improvement Strategies Questionnaire, IAISQ). The scale is based on the interpersonal affect classification (IAC; Niven, Totterdell, & Holman, 2009) and accurately distinguishes between the two primary means suggested in that model: positive engagement and acceptance. Through four studies we tested the factor structure, reliability, content, criterion, and predictive validity of the scale.
