This study investigated whether two instruments devised for people with mental illness, the Satisfaction with Daily Occupations (SDO) instrument and the Manchester Short Assessment of Quality of Life (MANSA), showed appropriate psychometric properties in terms of internal consistency, convergent/divergent validity, and discriminant validity when used with other samples. The study group comprised two female samples, one with physical disability (scleroderma) and one reference sample without known illness. It was hypothesized that the associations from SDO would be low or moderate to both general life satisfaction and self-rated health. The results confirmed that the associations were equal in size in both samples, but still the relationship to general life satisfaction in the scleroderma sample was somewhat higher than expected. Regarding the MANSA quality of life, the hypotheses were that the quality of life-index would show high correlations with general life satisfaction and moderate with self-rated health, and these hypotheses were confirmed for the reference sample, indicating that quality of life as measured by the MANSA converged with general life satisfaction but mainly diverged from self-rated health. In the scleroderma sample, the association to health was higher than expected. Both instruments appeared to reflect constructs that were stable across the two investigated groups, and both measures could distinguish the disability group from the healthy group. The SDO obtained a good value on internal consistency in the sample with scleroderma but a somewhat low value in the reference group, while the quality of life aspect of the MANSA exhibited good internal consistency in both samples. The instruments showed promising properties, indicating that they could be used for the target groups. However, both measures need further testing of psychometric properties.
本研究调查了为精神疾病患者设计的两种工具，即日常活动满意度（SDO）工具和曼彻斯特生活质量简短评估（MANSA），在用于其他样本时，在内部一致性、收敛/发散效度和区分效度方面是否显示出适当的心理测量特性。研究组包括两个女性样本，一个患有身体残疾（硬皮病），另一个为无已知疾病的参照样本。研究假设是，SDO与总体生活满意度和自评健康状况的关联将较低或为中等程度。结果证实，两个样本中的关联大小相等，但硬皮病样本中与总体生活满意度的关系仍略高于预期。关于MANSA生活质量，研究假设是生活质量指数与总体生活满意度将显示出高度相关性，与自评健康状况的相关性为中等，这些假设在参照样本中得到了证实，这表明MANSA所测量的生活质量与总体生活满意度趋同，但主要与自评健康状况相异。在硬皮病样本中，与健康状况的关联高于预期。两种工具似乎都反映了在两个被调查群体中都稳定的结构，并且两种测量方法都能够区分残疾组和健康组。SDO在硬皮病样本中的内部一致性值良好，但在参照组中的值略低，而MANSA的生活质量方面在两个样本中均表现出良好的内部一致性。这些工具显示出有前景的特性，表明它们可用于目标群体。然而，两种测量方法都需要进一步测试心理测量特性。
