Reciprocal longitudinal associations between positive body image and wellbeing among early-adult women

Abstract

This longitudinal study examined the prospective associations between body appreciation and wellbeing (i.e., self-esteem, depression, and emotional wellbeing) as well as body image flexibility and wellbeing among 490 women between 18–35 years of age (M = 28.63; SD = 4.27) residing in the United States. Women were contacted in three waves, each two months apart, and completed measures relating to each construct online. As a prerequisite of longitudinal analyses, this study found evidence of configural, metric, scalar, and strict invariance over time for each relevant measure. Cross-lagged panel modeling evidenced bidirectional associations between body appreciation and self-esteem between all waves and unidirectional associations between body appreciation and subsequent depression (negative) and body appreciation and subsequent emotional wellbeing (positive). Results showed bidirectional associations between body image flexibility, self-esteem, depression, and emotional wellbeing, although these bidirectional associations never occurred during the same interval between waves. This study evidences that higher body appreciation and body image flexibility are prospectively associated with increases in self-esteem, emotional wellbeing and decreases in depression, and also shows scenarios where the inverse associations also hold true. We also describe how this study complements existing cross-sectional research and the need to examine associations among more diverse participant groups.
