Acceptance and commitment therapy (ACT) emphasizes values and behavioral commitments to help individuals achieve goals and manage emotions. This study evaluated the preliminary psychometric properties of the ACTive Values Wheel, a smartphone application-based psychometric instrument. ACTive provides a weighted and idiographic index of individuals' self-reported values-directed behavior. One hundred sixty adults participated on an individual basis to complete the ACTive Values Wheel and questionnaire measures of well-being, psychological distress, psychological flexibility, and valued living to assess the convergent, incremental, discriminant, and criterion-related validity of the ACTive Values Wheel. The ACTive Values Wheel showed evidence of convergent and criterion-related validity through significant positive correlations with existing measures of valued living, emotional well-being, and openness to experience, respectively. Likewise, discriminant validity was evidenced by a nonsignificant correlation with age. However, evidence of incremental validity over and above existing measures of valued living was not found. These findings provide preliminary support for the psychometric properties of the ACTive Values Wheel. Accounting for the methodological limitations of the study, the ACTive Values Wheel shows potential as an accessible and interactive measure of self-reported values-directed behavior that could be extended to other languages and cultural contexts.

Pigeons were trained on many-to-one matching in which pairs of samples, each consisting of a visual stimulus and a distinctive pattern of center-key responding, occasioned the same reinforced comparison choice. Acquired equivalence between the visual and response samples then was evaluated by reinforcing new comparison choices to one set of samples, and examining generalization of these choices to the other samples. Three separate experiments found no evidence of such generalization, as indexed by performance on class-consistent versus class-inconsistent tests. Other tests showed that the pigeons' center-key response patterns during training had indeed served as a conditional cue for choice. These results do not support the hypothesis that different defined responses can become members of acquired equivalence classes. (Contains 10 figures and 2 tables.)
