Abstract

Introduction: Acceptance and Commitment Therapy (ACT) has gained increasing empirical support in workplace settings, highlighting the need for valid measures of psychological flexibility among healthcare professionals.

Objective: The objective of this study was to examine the unidimensional structure of the Work-Related Acceptance and Action Questionnaire (WAAQ), evaluate its internal consistency reliability, and assess validity evidence based on its associations with anxiety and depression.

Method: The participants were 182 Peruvian healthcare professionals who completed the WAAQ, the Patient Health Questionnaire-2 (PHQ-2), and the Generalized Anxiety Disorder Scale-2 (GAD-2).

Results: Confirmatory factor analysis supported the one-factor model (CFI > 0.95, TLI > 0.95, RMSEA < 0.06, and SRMR < 0.08), and the scale demonstrated adequate internal consistency (ω = 0.87). As expected, psychological flexibility showed a small-to-moderate correlation with depression (r_s = -0.28, IC 95% [-0.41, -0.14], p < 0.001) and a moderate correlation with anxiety (r_s = -0.30, IC 95% [-0.42, -0.16], p < 0.001).

Conclusion: The findings suggest that the WAAQ is a valid and reliable measure of psychological flexibility in the workplace among healthcare professionals.
