本研究的目的是检查是否可以在接受减肥手术的青少年样本中识别出亚组。参与者是 125 名参加减肥手术计划并转介进行精神病学评估的严重肥胖青少年。通过自我报告和临床医生评定的抑郁症状、青少年自我报告量表的总问题、焦虑严重程度、饮食病理、精神病诊断、生活质量和家庭功能进行潜在类别分析。三类模型产生了与数据最佳的整体拟合。 “饮食病理学”课程中的青少年表现出高水平的饮食失调和其他精神病理学症状。第二类或“低精神病理学”类表现出的心理社会问题最少，而第三类的青少年在精神病理学测量方面处于中间水平，这与“非特异性精神病理学”一致。潜在类别分析在严重肥胖青少年的异质样本中确定了具有不同精神病理学水平的同质亚组。本研究中临床相关亚组的识别为检查青少年减肥手术候选者的精神病理学提供了重要的初步手段，并为未来的研究提出了一些途径。
The purpose of this study was to examine whether subgroups could be identified among a sample of adolescents presenting for bariatric surgery. Participants were 125 severely obese adolescents enrolled in a bariatric surgery program referred for a psychiatric evaluation. A latent class analysis was conducted with self-report and clinician-rated measures of depressive symptoms, total problems by the Youth Self-Report Scale, anxiety severity, eating pathology, psychiatric diagnoses, quality of life, and family functioning. A 3-class model yielded the best overall fit to the data. Adolescents in the “eating pathology” class demonstrated high levels of both eating disordered and other psychopathology. The second class, or “low psychopathology” class exhibited the fewest psychosocial problems, whereas adolescents in the third class were intermediate on measures of psychopathology, which is consistent with “non-specific psychopathology.” The latent class analysis identified homogeneous subgroups with different levels of psychopathology among a heterogeneous sample of severely obese adolescents. The identification of clinically relevant subgroups in this study offers an important initial means for examining psychopathology among adolescent bariatric surgery candidates and suggests a number of avenues for future research.
