Development and Validation of a Psychological Scale for Bariatric Surgery: The Baritest

Abstract

BACKGROUND: It is recommended that bariatric surgery candidates undergo psychological assessment. However, no specific instrument exists to assess the psychological well-being of bariatric patients, before and after surgery, and for which all constructs are valid for both genders. AIMS: This study aimed to develop and validate a new psychometric instrument to be used before and after bariatric surgery in order to assess psychological outcomes of patients. METHODS: This is a cross-sectional study that composed of 660 individuals from the community and bariatric patients. BariTest was developed on a Likert scale consisting of 59 items, distributed in 6 constructs, which assess the psychological well-being that influences bariatric surgery: emotional state, eating behavior, quality of life, relationship with body weight, alcohol consumption, and social support. Validation of BariTest was developed by the confirmatory factor analysis to check the content, criteria, and construct. The R statistical software version 3.5.0 was used in all analyses, and a significance level of 5% was used. RESULTS: Adjusted indices of the confirmatory factor analysis model indicate adequate adjustment. Cronbach’s alpha of BariTest was 0.93, which indicates good internal consistency. The scores of the emotional state, eating behavior, and quality of life constructs were similar between the results obtained in the community and in the postoperative group, being higher than in the preoperative group. Alcohol consumption was similar in the preoperative and postoperative groups and was lower than the community group. CONCLUSIONS: BariTest is a reliable scale measuring the psychological well-being of patients either before or after bariatric surgery.

Depressive and Eating Disorders in Patients Post-Bariatric Surgery With Weight Regain: A Descriptive Observational Study

“…These other habits may be equally or more relevant than BED itself postoperatively. As a response to external stressors, eating small portions of high-caloric foods rather than huge amounts still stimulates the brain’s reward system, since these neuropsychiatric pathways are not altered with the surgery 12 . Hanvold et al 13 found that smokers had a significantly lower WR, which supports the hypotheses that finding ways to feed neuropsychological pathways is a major cause of WR maintenance 19 , 30 .…”

“…The HADS-D is a self-administration screening scale. The severity of depression is classified as normal (0-7), mild (8)(9)(10), moderate (11)(12)(13)(14)(15), and severe (16)(17)(18)(19)(20)(21), with Cronbach's internal consistency alpha coefficient of 0.90.…”

Barimep: A Tool for Training Bariatric Surgery Patients

“…The difficulty for humans to modify behavior, especially eating behavior, has been studied 3 . Problematic eating behaviors, such as binge and emotional eating, have been characterized in obesity 5 . The performance of routine activities on “autopilot” can cause the patient to eat on impulse and without control 8 .…”
