The MMPI was administered to 36 male low back pain patients at the Seattle Veterans Administration Hospital. The patients were divided into three groups of 12 each. The organic group contained patients who had an organic basis for their pain. The functional group contained patients who had no organic basis for their pain. The mixed group contained patients who had some organic basis for their pain, but one that was thought to be insufficient to account for the pain they were reporting. The mixed and functional groups differed significantly from the organic group on the Hs, Hy, Pt, Sc, Hy-O, D-O, and DOR scales. The mixed and functional groups differ significantly from each other only on the Hy-O scale. The special low back pain scales of Lb and DOR were found to have little utility when used separately. When used in conjunction, however, the scales discriminated correctly 75% of the time.
明尼苏达多相人格测验（MMPI）应用于西雅图退伍军人管理局医院的36名男性腰痛患者。患者被分为三组，每组12人。器质性组包含有疼痛器质性基础的患者。功能性组包含无疼痛器质性基础的患者。混合组包含有一定疼痛器质性基础，但被认为不足以解释其报告疼痛的患者。在疑病（Hs）、癔症（Hy）、精神衰弱（Pt）、精神分裂症（Sc）、Hy-O、D-O和抑郁或癔症（DOR）量表上，混合组和功能性组与器质性组有显著差异。混合组和功能性组仅在Hy-O量表上有显著差异。发现单独使用时，特殊的腰痛量表Lb和DOR效用不大。然而，联合使用时，这些量表在75%的时间里能正确区分。
