Background:
Experiential avoidance and psychological inflexibility have been recently found to be important constructs related to a wide range of psychological disorders and quality of life. The current study presents psychometric and factor structure data concerning the Spanish translation of a general measure of both constructs: the Acceptance and Action Questionnaire - II (AAQ-II).
Method:
Six samples, with a total of 712 participants, from several independent studies were analyzed.
Results:
Data were very similar to the ones obtained in the original AAQ-II version. The internal consistency across the different samples was good (between a= .75 and a= .93). The differences between clinical and nonclinical samples were statistically significant and the overall factor analysis yielded to a one-factor solution. The AAQ-II scores were significantly related to general psychopathology and quality of life measures.
Conclusions:
This Spanish translation of the AAQ-II emerges as a reliable and valid measure of experiential avoidance and psychological inflexibility.

Avoidance learning is powerful because it maintains behavior in the absence of the...
