title: The construct validity of acceptance: a multitrait-multimethod investigation.
abstract: Despite increasing clinical and empirical attention, the construct validity of acceptance has not been extensively investigated. The present study utilized a multitrait-multimethod design and a correlated trait-correlated method minus one [CT-C(M-1)] confirmatory factor analytic model to assess acceptance's convergent validity across methods and discriminant validity in comparison to cognitive reappraisal and perceived emotional control in a sample of 210 outpatients with anxiety and mood disorders. In addition, the study evaluated acceptance's concurrent validity by investigating the extent to which it was associated with variables of clinical interest over and above the two rival constructs. Results of confirmatory factor analyses supported acceptance's convergent and discriminant validity in comparison to the two neighboring constructs, and thereby provided partial support for its construct validity. However, contrary to prediction, acceptance was not significantly associated with concurrent validation measures. These results are discussed in the context of acceptance's potential therapeutic utility and functional relationships with associated constructs.
