Abstract

While affect is frequently measured with experience sampling methodology (ESM), the affective structure at the between-and within-person level has not been thoroughly investigated. We investigated the affective structure at the between-and within-person level, its invariance across different ESM protocols, and its reliability. Participants (N = 147) were randomly assigned to receive either a 30 or 60 item questionnaire three, six, or nine times per day, resulting in 72-75 participants per questionnaire length and 48-50 participants per sampling frequency. Momentary affect was assessed with 8 or 18 items. At both levels, a structure with two correlated factors showed the best fit compared to an orthogonal and a unidimensional model. A structure with additional freed residual correlations was invariant across protocols at the within-person level and showed high reliability. We observed indications of a more discrete affective structure within than between persons.(c) 2021 Elsevier Inc. All rights reserved.
