Measuring experiential avoidance and psychological inflexibility: The Spanish version of the Acceptance and Action Questionnaire-II

Psychometric analysis of the Spanish translation of the AAQ-II in six samples (n=712). The version showed good internal consistency (α between .75 and .93), unidimensional solution, and expected relationships with symptomatology and quality of life, supporting its use for measuring experiential avoidance and inflexibility in Spanish-speaking contexts.
