    Journal: Obes Surg; 2023 Jun; 33(6):1806-1819. PubMed ID: 37061626.
    Abstract:
    BACKGROUND: The use of psychological screening instruments prior to bariatric surgery has been well established. However, there is currently no specific literature on psychological screening of candidates for reoperative bariatric surgery. METHODS: This study evaluated archival data for 40 women who were candidates for reoperative bariatric surgery and completed the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF). Profile analysis examined differences between patient groups who did and did not undergo reoperative surgery. MMPI-2-RF profiles for reoperative patients then were compared to previous samples of preoperative and postoperative patients. Hierarchical linear modeling was used to predict BMI following reoperative surgery over a 12-month period based on MMPI-2-RF scales while controlling for age and initial BMI. RESULTS: Profile analysis results showed no significant differences on MMPI-2-RF scale scores between reoperative candidates who did and did not undergo a second surgery. With some minor differences attributed to minimization of symptoms, there were no systematic differences in MMPI-2-RF scale scores for reoperative surgery patients compared to preoperative and postoperative patient groups. BMI outcomes over a 12-month period showed that age and initial BMI were significantly better predictors than MMPI-2-RF scores. CONCLUSIONS: Administration of MMPI-2-RF for reoperative bariatric surgery patients likely is equivalent to its typical use in preoperative screening. Only the MMPI-2-RF Disconstraint scale showed any relationship to BMI outcomes over time following reoperative surgery.
