The aim of the study was to examine the associations between personality, weight loss and obesity-related well-being post-bariatric surgery. It was hypothesised that persons who had undergone bariatric surgery who exhibit Extraversion, Conscientiousness, Agreeableness and Intellect/Imagination will have greater obesity-related well-being; whereas, those low on Emotional stability will have poorer obesity well-being.
The cross-sectional sample comprised 127 females who had received bariatric surgery. The average age of participants was 45 years. Quality of life was measured using the Obesity-Related Well-Being scale (ORWELL 97). Personality was assessed with the International Personality Item Pool (IPIP) 50-item measure of the Five-Factor Model.
The mean BMI for the sample was 34.13 (SD = 7.8). Females with a larger BMI who had undergone bariatric surgery had lower obesity-related well-being. Conscientiousness was negatively associated with BMI. Separate Hierarchical regression analyses found that Emotional stability (Beta = - .43, - .47, - .36) and Agreeableness (Beta = .27, .29, .25) predicted overall well-being, symptom occurrence and subjective relevance of distress, respectively. BMI predicted occurrence of symptoms (Beta = .23).
The findings have implications for the development of personality-informed interventions for bariatric patients in enhancing well-being and weight-loss maintenance following surgery.
Level III: Evidence obtained from well-designed cohort or case-control analytic studies.
本研究旨在探讨人格特质、减肥与减重手术后肥胖相关幸福感之间的关联。研究假设接受过减重手术的人，如果具有外向性、尽责性、宜人性和智慧/想象力，他们的肥胖相关幸福感会更高；而情绪稳定性较低的人肥胖幸福感则较差。
本横断面研究样本由 127 名接受过减重手术的女性组成。参与者的平均年龄为 45 岁。使用肥胖相关幸福感量表（ORWELL97）来衡量生活质量。人格特质采用国际人格项目池（IPIP）50 项五因素模型进行评估。
样本的平均 BMI 为 34.13（SD=7.8）。接受减重手术的女性 BMI 越大，肥胖相关幸福感越低。尽责性与 BMI 呈负相关。单独的分层回归分析发现，情绪稳定性（Beta=-.43，-.47，-.36）和宜人性（Beta=.27，.29，.25）分别预测整体幸福感、症状发生和主观痛苦的相关性。BMI 预测症状的发生（Beta=.23）。
这些发现为发展针对肥胖患者的人格干预措施提供了依据，以增强手术后的幸福感和体重维持。
III 级：来源于精心设计的队列或病例对照分析研究的证据。
