To investigate the cross-sectional relationship between subjective quality of life and sociodemographic clinical and social factors over three points of assessment during a 6-year follow-up, and to investigate longitudinal predictors of subjective quality of life.
We investigated a sample of people with severe mental illness (n = 92), mainly with a psychosis diagnosis, at baseline and at an 18-month and 6-year follow-up. Measures included the Lancashire quality of life profile, Manchester short assessment of quality of life, Symptom Check List 90, Camberwell Assessment of Needs and the Interview Schedule for Social Interaction.
Cross-sectionally subjective quality of life was associated to self-reported symptoms, social network and unmet needs. However, these determinants varied in importance between points of assessment. Longitudinal predictors of subjective quality of life were changes in self-reported symptoms and social network.
There was a rather consistent set of determinants of subjective quality of life over time. Social network seems to be an important factor with relevance for improvements in subjective quality of life, however largely overlooked in earlier studies within the field.
调查在6年随访期间三个评估点上主观生活质量与社会人口统计学、临床及社会因素之间的横断面关系，并调查主观生活质量的纵向预测因素。
我们对92名患有严重精神疾病（主要诊断为精神病）的患者样本进行了调查，在基线、18个月及6年随访时进行评估。测量指标包括兰开夏生活质量概况、曼彻斯特生活质量简短评估、症状自评量表90、坎伯韦尔需求评估及社会互动访谈日程表。
横断面来看，主观生活质量与自我报告的症状、社会网络及未满足的需求相关。然而，这些决定因素在各评估点的重要性有所不同。主观生活质量的纵向预测因素是自我报告症状及社会网络的变化。
随着时间推移，主观生活质量存在一组较为一致的决定因素。社会网络似乎是一个对主观生活质量改善具有相关性的重要因素，然而在该领域早期研究中很大程度上被忽视了。
