: Numerous studies have focused on psychological assessment of bariatric surgery candidates, aiming to identify which psychological variables, including personality characteristics, are related to successful surgical prognosis.
: To analyze, by means of a systematic literature review, longitudinal studies that investigated personality traits and disorders as possible predictors of outcomes in bariatric surgery.
: PsycInfo, PubMed, and Scopus databases were searched for studies published between 2005 and 2015, using the keywords "bariatric" AND "personality." Quantitative longitudinal studies in English, Portuguese, or Spanish were selected for review if they assessed personality as an outcome predictor of BS in people aged 18 years or older.
: Sixteen articles were analyzed. The results of this review suggest that externalizing dysfunctions might be associated with less weight reduction, while internalizing dysfunctions appear to be associated with somatic concerns and psychological distress. The persistence dimension (of temperament in Cloninger's model) was positively associated with greater weight loss, while neuroticism (Five Factor Model) and the occurrence of personality disorders were not predictive of weight loss. Furthermore, the results indicate a tendency towards a reduction in personality disorders and neuroticism scores, and an increase in extroversion scores, after BS.
: Assessment of personality characteristics, whether to identify their predictive power or to detect changes during the BS process, is important since it can provide grounds for estimating surgical prognosis and for development of interventions targeting this population.
众多研究聚焦于对减肥手术候选人的心理评估，旨在确定哪些心理变量（包括人格特征）与手术预后成功相关。
通过系统的文献综述，分析纵向研究，这些研究调查了人格特质和障碍作为减肥手术结果的可能预测因素。
在PsycInfo、PubMed和Scopus数据库中搜索2005年至2015年发表的研究，使用关键词“减肥”和“人格”。如果定量纵向研究用英语、葡萄牙语或西班牙语发表，且评估了人格作为18岁及以上人群减肥手术结果的预测因素，则选择进行综述。
分析了16篇文章。本综述结果表明，外化功能障碍可能与体重减轻较少有关，而内化功能障碍似乎与躯体问题和心理困扰有关。持续性维度（克隆宁格模型中的气质维度）与更大的体重减轻呈正相关，而神经质（五因素模型）和人格障碍的发生并不能预测体重减轻。此外，结果表明减肥手术后人格障碍和神经质得分有降低趋势，外向性得分有增加趋势。
对人格特征的评估，无论是为了确定其预测能力还是为了检测减肥手术过程中的变化，都很重要，因为它可以为估计手术预后和制定针对该人群的干预措施提供依据。
