Abstract: The structure of affect is often studied through the circumplex: a circular model on which similar (i.e. highly correlated) states lie close to each other. While very informative, the circumplex lacks simple structure, as items spread more or less uniformly around its perimeter. Consequently, affect scales loading close to each other on the circumplex are likely to overlap substantially and have poor discriminant validity. The present study aims to identify distinct dimensions of affect. Based on theory and previous findings, the following hypotheses were formulated: (1) only positive affect items loading on the most distant segments of the circumplex will form two separate factors and approximate a simple structure; (2) moderate-arousal positive affect (MAP) should be representative of general positive affect; (3) MAP should substantially overlap with life satisfaction (LS). The hypotheses were tested in an Australian sample (N = 424) through exploratory analyses and structural equation modelling, and were all supported. The paper contributes to current research by encouraging a more parsimonious measurement of positive affect. Studies focusing on different levels of arousal may only use scales of calmness and energy. Studies that aim to measure positive affect in general may simply use a MAP scale, as a promising alternative to the Positive and Negative Affect Schedule (PANAS, Watson et al. in J Pers Soc Psychol 54(6):1063–1070, 1988 ). Finally, since MAP also explained 68 % of the variance in LS, it shows potential as a brief measure of subjective well-being. Copyright Springer Science+Business Media Dordrecht 2015
