Self-care model and body image in adults after a bariatric surgery. / Modelo de autocuidado e imagem corporal em adultos pós cirurgia bariátrica.

OBJECTIVE: the aim of the present article was to test a self-care model explained by the relationship between self-efficacy, body image, obsessive-compulsive disorder, and depression in people with bariatric surgery in the city of Tijuana, Baja California, Mexico. METHOD: this was a correlational cross-sectional study carried out between August and December 2020. Validated instruments were administered to 102 participants to measure their self-care capacity, general self-efficacy, psychopathological symptoms, and body image perception and satisfaction. The variables of interest were analyzed using descriptive statistics and the Pearson and Spearman correlation coefficients were used to develop a model using path analysis. RESULT: a significant model was obtained with adequate goodness-of-fit indicators (chi-square χ2 (8) = 11.451, p = .177; root mean square error of approximation (RMSEA)= 0.000; goodness-of-fit index (GFI)= 0.965; comparative fit index (CFI)= 0.985; parsimonious normed fit index (PNFI)= 0.509, and Akaike information criterion (AIC)= 37.451). Self-efficacy (Zß=0.294) and body image dissatisfaction (So= -0.376) were shown to influence self-care abilities while psychopathological symptoms influenced body dissatisfaction: obsessive-compulsive disorder (Zß=0.370) and depression (Zß=0.320). CONCLUSION: adequate levels of self-efficacy and body satisfaction predict a high capacity for self-care.
