Do fluctuations in positive affective and physical feeling states predict physical activity and sedentary time?

ABSTRACT:

Objectives

Higher levels of positive affect and feelings of energy and vitality are associated with greater physical activity (PA) and lower sedentary time (ST). However, whether fluctuations in these feelings contribute to the regulation of these behaviors is unclear. This study examined the extent to which within-person variability in positive affect and feeling energetic predicted participants' overall levels of PA and ST.

Design

This analysis combined data from four ecological momentary assessment (EMA) studies (age_range: 8-73 years) with ambulatory monitoring via waist-worn accelerometry (N=661).

Methods

Positive affect and energy were assessed through EMA several times per day across 4-7 days. Accelerometer data was used to create the following behavi
