Functionality appreciation is a component of positive body image that refers to respecting and honoring the body for what it is capable of doing. A growing number of studies have investigated the features, correlates, and outcomes of functionality appreciation, yet a synthesis of this literature is missing. We conducted a systematic review and meta-analysis of research on functionality appreciation. Fifty-six studies were included (85 % cross-sectional). Random effects meta-analyses were performed on 21 cross-sectional correlates and on seven randomized trials of psychological interventions that assessed functionality appreciation as an outcome. Meta-analyses showed that functionality appreciation was consistently associated with fewer body image problems, lower levels of eating disorder symptoms, and better mental health and wellbeing. Functionality appreciation was unrelated to age and gender, but weakly (and negatively) related to body mass index. Preliminary evidence from prospective designs suggests that the appreciation of body functionality may promote adaptive eating patterns and prevent maladaptive eating and body image patterns over time. Psychological interventions designed to cultivate functionality appreciation in full or in part produced greater improvements in this construct than control conditions. Findings confirm that functionality appreciation is associated with numerous wellbeing constructs and could serve as a potentially useful target for intervention.
