To test the hypothesis that self-care capacity can be predicted by tests of mental functioning, the performances of patients in a long-term care institution on a Self-Care Scale were compared with their scores on the Short Portable Mental Status Questionnaire (SPMSQ) and a Mental Competence Scale. The Self-Care Scale measures ability to perform activities of daily living; the SPMSQ assesses memory, orientation, and calculation; and the Mental Competence Scale measures ability to respond sensibly to interview questions and to judge the environment. Many people who had poor scores on the SPMSQ were able to perform activities of daily living in the nursing home setting, but none whose scores on the Mental Competence Scale were fair or poor were independent in activities of daily living. Despite the fact that both the Self-Care Scale and the Mental Competence Scale are still in the developmental stages, the author concludes that the SPMSQ is not an adequate predictor of capacity for self-care. Moreover, the ability to respond appropriately to an interview may be more relevant for daily functioning than are tests of mental status. The three methods of assessment used in this study measure distinct yet complementary components of functioning that need to be considered in evaluating a mentally impaired elderly person.
为检验心理功能测试能否预测自我护理能力这一假设，研究人员将一家长期护理机构中患者在自我护理量表上的表现与其在简易便携式精神状态问卷（SPMSQ）和心理能力量表上的得分进行了比较。自我护理量表衡量日常生活活动能力；SPMSQ评估记忆、定向和计算能力；心理能力量表衡量对访谈问题做出明智反应以及判断环境的能力。许多在SPMSQ上得分较低的人在养老院环境中能够进行日常生活活动，但在心理能力量表上得分中等或较差的人在日常生活活动中均无法自理。尽管自我护理量表和心理能力量表仍处于发展阶段，但作者得出结论，SPMSQ并非自我护理能力的充分预测指标。此外，与精神状态测试相比，对访谈做出适当反应的能力可能与日常功能更为相关。本研究中使用的三种评估方法测量了功能中不同但互补的组成部分，在评估精神受损的老年人时需要加以考虑。
