This study aimed to examine the reliability and validity of the Korean version of the Avoidance and Fusion Questionnaire for Youth(AFQ-Y; Greco, Lambert, & Baer, 2008), a child-report measure of psychological inflexibility. Elementary and middle school students(n=721) completed Korean version of AFQ-Y(K-AFQ-Y), White Bear Suppression Inventory(WBSI), Acceptance and Action Questionnaire(AAQ), Revised Children’s Manifest Anxiety Scale(RCMAS), Youth Self-Report(YSR), and Concise Measure of Subjective Well-Being (COMOSWB). The K-AFQ-Y showed adequate internal consistency reliability (Cronbach’s α=.87) and good test-retest reliability(r=.83). In addition, confirmatory factor analysis showed that K-AFQ-Y fitted a one-factor measurement model. The K-AFQ-Y correlated positively with anxiety, depression, somatic complaint and problem behavior, and negatively with subjective well-being. Also, The K-AFQ-Y correlated as expected with conceptually overlapping process, thought suppression and acceptance. Even after removing the effects of related constructs(thought suppression and acceptance), the K-AFQ-Y correlated significantly in the expected directions with all measures. These results support the convergent and construct validity of K-AFQ-Y. Overall, the results suggest that the K-AFQ-Y may be an useful child-report measure of core acceptance and commitment therapy process, psychological inflexibility. Finally, the implication and limitation of this study were discussed.
