Self-objectification and depression: An integrative systematic review

Background Objectification Theory positions self-objectification as a cause of depression. In particular, the authors offer Objectification Theory as a partial explanation for the higher prevalence of depression among women than men. To investigate the validity of this theory, we undertook a systematic review of quantitative studies that have investigated self-objectification as a predictor of depression. Methods Studies were identified by searching the PsycINFO, Medline, EMBASE and Cochrane Library databases. Search terms were 'objectif∗' OR 'body conscious∗' AND 'depressi∗' OR 'dysthymi∗' OR 'mood disorder'. To be eligible, studies were required to be in the English-language, to include a measure of depression and a measure of self-objectification. Studies were excluded if they did not explicitly examine the association between these variables. Results Among women most studies found a mediated effect for self-objectification on depression. All studies including adolescents found a direct effect. Each of the two prospective longitudinal studies found that an increase in self-objectification over time was associated with a concomitant increase in depression, suggesting a causal relationship. Among men the results were mixed. Limitations The review did not include a quantitative synthesis due to the heterogeneity of the included observational studies. The majority of the studies were cross-sectional precluding conclusions concerning causality. Generalisations to culturally and linguistically diverse populations must be made with caution given the limited cultural diversity within the studies Conclusions Self-objectification may be a useful predictor of depression, particularly among women and adolescents, and may have clinical relevance among these populations
