title: The Abbreviated Character Strengths Test (ACST): A Preliminary Assessment of Test Validity.
abstract: The 24-item Abbreviated Character Strengths Test (ACST) was developed to efficiently measure character strengths (Peterson, Park, & Castro, 2011 ). However, its validity for this purpose has not yet been sufficiently established. Using confirmatory factor analysis to test a series of structural models, only a modified bifactor model showed reasonably acceptable fit. Further analyses of this model failed to demonstrate measurement invariance between male and female respondents. Relationships between ACST dimension and Big Five personality trait scores were generally weak-to-moderate, and support for hypotheses regarding each ACST virtue's expected correspondence with specific Big Five dimensions was mixed. Finally, scores on ACST dimensions accounted for a combined 12% of the variance in satisfaction with life scores, after controlling for socially desirability. Although an abbreviated measure of character strengths represents a practical need, considerable improvements to the ACST are needed for it to adequately meet this purpose.
