Revised Avoidance & Fusion Questionnaire for Youth (AFQ-Y; Greco, Murrell, & Coyne, 2005)

Printer-friendly version

The Avoidance and Fusion Questionnaire for Youth (AFQ-Y; Greco, Murrell, & Coyne, 2005) is a 17-item measure that asks respondents to rate how true each item is for them (0 = Not at All True; 4 = Very True). Items are tied to ACT’s model of human suffering and were generated to represent a theoretically cohesive conceptualization of psychological inflexibility fostered by: (1) Cognitive fusion (e.g., “My thoughts and feelings mess up my life,” “The bad things I think about myself must be true”); (2) Experiential avoidance (e.g., “I push away thoughts and feelings that I don’t like”); and (3) Inaction or behavioral ineffectiveness in the presence of unwanted internal experiences (e.g., “I can’t be a good friend when I feel upset”).

Consistent with the theory underlying acceptance and commitment therapy (ACT), items converged into a 17-item scale (AFQ-Y) and an 8-item short form (AFQ-Y8). Results of classical test theory, factor analysis, and item response theory support the psychometric properties of the 17-item version of the AFQ-Y and AFQ-Y8. Overall, research suggests that the AFQ-Y may be a useful and child-friendly measure of core ACT processes.
