Abstract
BACKGROUND
Bariatric surgery is an effective treatment for the obesity epidemic, but the poor attendance and adherence rates of post-surgery recommendations threaten treatment effectiveness and health outcomes. Preoperatively, we investigated the unique contributions of clinical (e.g., medical and psychiatric comorbidities), sociodemographic (e.g., sex, age, and educational level), and psychopathological variables (e.g., binge eating severity, the general level of psychopathological distress, and alexithymia traits) on differing dimensions of adherence in a group of patients seeking bariatric surgery.
METHODS
The final sample consisted of 501 patients (346 women). All participants underwent a full psychiatric interview. Self-report questionnaires were used to assess psychopathology, binge eating severity, alexithymia, and three aspects of adherence: knowledge, attitude, and barriers to medical recommendations.
RESULTS
Attitude to adherence was associated with alexithymia (β = -2.228; p < 0.001) and binge eating disorder (β = 0.103; p = 0.047). The knowledge subscale was related to medical comorbidity (β = 0.113; p = 0.012) and alexithymia (β = -2.256; p < 0.001); with age (β = 0.161; p = 0.002) and psychiatric comorbidity (β =0.107; p = 0.021) manifesting in the barrier subscale.
CONCLUSION
We demonstrated that alexithymia and psychiatric and eating disorders impaired adherence reducing attitude and knowledge of treatment and increasing the barriers. Both patient and doctor can benefit from measuring adherence prior to surgery, with a qualitative approach shedding light on the status of adherence prior to the postsurgical phase when the damage regarding adherence is, already, done.
