Presurgical psychological screening is used to identify factors that may impact postoperative adherence and surgical outcomes in bariatric surgery candidates. Minnesota Multiphasic Personality Inventory - 2 Restructured Form (MMPI-2-RF) findings have demonstrated utility for this task.
To explore whether there are clinically meaningful gender, ethnicity, or age differences in presurgical MMPI-2-RF scores and the validity of these scores in bariatric surgery candidates.
The sample was composed of 872 men and 2337 women. Ethnicity/race groups included 2,204 Caucasian, 744 African American, and 96 Hispanic individuals. A sample of 165 were not included in the ethnicity/race analyses because they were of another descent. Ages groups included 18-35 year olds (n = 454), 36-49 year olds (n = 1154), 50-64 year olds, (n = 1246), and 65 years old or older (n = 355). Validity data, obtained via a retrospective chart review, were available for a subset patients (n = 1,268) who were similarly distributed. Step-down hierarchical regression analyses were conducted to assess for differential validity.
Bariatric surgery candidates produced comparable MMPI-2-RF scores in all subsamples, indicating that the test norms generalize across demographic groups. Validity findings were also generally comparable, indicating that MMPI-2-RF scores have the same interpretive implications in demographically diverse subgroups of bariatric surgery candidates.
The MMPI-2-RF can assist in presurgical psychological screening of demographically diverse bariatric surgery candidates.
术前心理筛查用于识别可能影响减肥手术候选者术后依从性和手术结果的因素。明尼苏达多相人格调查表第二版修订版（MMPI-2-RF）的研究结果已证明该测试在这项任务中的效用。
探讨减肥手术候选者术前MMPI-2-RF分数是否存在具有临床意义的性别、种族或年龄差异，以及这些分数的有效性。
样本包括872名男性和2337名女性。种族/族裔群体包括2204名白种人、744名非裔美国人以及96名西班牙裔个体。有165名个体因属于其他血统而未纳入种族/族裔分析。年龄组包括18至35岁（n = 454）、36至49岁（n = 1154）、50至64岁（n = 1246）以及65岁及以上（n = 355）。通过回顾性病历审查获得的效度数据可用于分布相似的部分患者（n = 1268）。进行逐步分层回归分析以评估差异效度。
减肥手术候选者在所有子样本中的MMPI-2-RF分数相当，表明测试常模在不同人口统计学群体中具有普遍性。效度研究结果通常也相当，表明MMPI-2-RF分数在人口统计学特征不同的减肥手术候选者亚组中具有相同的解释意义。
MMPI-2-RF可协助对人口统计学特征不同的减肥手术候选者进行术前心理筛查。
