Predictors of Post-bariatric Surgery Appointment Attendance: the Role of Relationship Style

Abstract

Attendance at bariatric surgery follow-up appointments has been associated with bariatric surgery outcomes. In this prospective study, we sought to examine psychosocial predictors of attendance at post-operative follow-up appointments. Consecutive bariatric surgery patients (n = 132) were assessed pre-surgery for demographic variables, depressive symptoms, and relationship style. Patients were followed for 12 months post-surgery and, based on their attendance at follow-up appointments, were classified as post-surgery appointment attenders (attenders--attended at least one appointment after post-operative month 6) or post-surgery appointment non-attenders (non-attenders--did not attend at least one appointment after post-operative month 6). Psychosocial and demographic variables were compared between the attender and non-attender groups. Multivariate logistic regression was used to identify significant predictors of attendance at post-bariatric surgery follow-up appointments. At 12 months post-surgery, 68.2 % of patients were classified as attenders. The non-attender group was significantly older (p = 0.04) and had significantly higher avoidant relationship style scores (p = 0.02). There was a trend towards patients in the non-attender group living a greater distance from the bariatric center (p = 0.05). Avoidant relationship style was identified as the only significant predictor of post-operative appointment non-attendance in the logistic regression analysis. These findings suggest that avoidant relationship style is an important predictor of post-bariatric surgery appointment non-attendance. Recognition of patients' relationship style by bariatric surgery psychosocial team members may guide the delivery of interventions aimed at engaging this patient group post-surgery.
