A multivariate clustering procedure was used to identify replicable, homogeneous MMPI profile subgroups among three independent cohorts of male (N = 233) and female (N = 315) low back pain ((LBP) patients. Three subgroups were replicated across all male cohorts and four subgroups were replicated across all female cohorts. Multiple discriminant analysis showed that for both male and female patients between-subgroup variability was significantly greater than within-subgroup variability. The results suggest that LBP patients may not be solely characterized by MMPI profiles featuring the "conversion V" configuration. Examination of the profile subgroups also suggests there may be distinct, pain-related, behavioral attributes associated with each subgroup which might have important implications for practitioners' choice of treatment modalities. Suggestions are made for research regarding the development of specific, optimal treatments for various LBP patient subgroups.
采用多变量聚类程序，在三组独立的男性（N = 233）和女性（N = 315）腰痛（LBP）患者队列中识别可重复的、同质的明尼苏达多相人格调查表（MMPI）剖面图亚组。在所有男性队列中重复出现了三个亚组，在所有女性队列中重复出现了四个亚组。多重判别分析表明，对于男性和女性患者，亚组间的变异性显著大于亚组内的变异性。结果表明，腰痛患者可能不能仅以具有“转换V”构型的MMPI剖面图为特征。对剖面图亚组的检查还表明，每个亚组可能存在与疼痛相关的独特行为属性，这可能对从业者选择治疗方式具有重要意义。针对为不同腰痛患者亚组开发特定的最佳治疗方法的研究提出了建议。
