The Construction of an Inventory of Responses to Positive Affective States

We report the construction of the Inventory of Responses to Positive Affective States (IRPAS), a trait, self-report measure of response to positive affect. The IRPAS differs from existing measures by addressing a broad set of responses to positive affect, including but not limited to affect regulation strategies, and by considering relevance to a range of positive affective states. In Study 1, qualitative interviews were conducted with 21 individuals to inform item content. In Study 2, factor analysis of the final item set was conducted using data from 540 individuals. Study 3 investigated convergent and divergent validity and test–retest reliability of the resulting 59-item IRPAS. The IRPAS was found to be reliable and valid, and to make a unique contribution to the literature on response to positive mood. Further validation studies should be conducted; potential applications include exploration of positive affect functioning in both clinical and non-clinical populations.
