The aim of this study is to analyse the validity and reliability of the functional social support questionnaire, Duke-UNC-11.
Descriptive. Crossover study.
Urban health centre.
656 patients were interviewed in their homes. 60 had the questionnaire repeated (30 self-filled and 30 using an interviewer) an average of 6 days later.
The intraclass correlation coefficients of the 11 items in the Duke-UNC-11 were above 0.50, for both self-filled and interviewer questionnaires; the ones on the scale were 0.92 and 0.80, respectively. The factorial analysis separated two sub-scales, confidential support (7 items) and affective support (4 items). Low social support was significantly associated to: being over 40, widowed or divorced, living alone, over-user, worse subjective health, greater chronic morbidity, mental health disorder and family dysfunction. The multiple linear regression equation managed to explain 30% of the variability of social support, in which family function (family APGAR) explained 23.5%, education 3.3%, perception of internal health control 2%, mental health 1.2% and perception of susceptibility to/seriousness of illness 0.3%.
The questionnaire Duke-UNC-11 is valid and reliable.
本研究旨在分析杜克大学-北卡罗来纳大学社会支持问卷（Duke-UNC-11）的有效性和可靠性。
描述性交叉研究。
城市健康中心。
对656名患者进行了家访。其中60名患者在平均6天后重复填写问卷（30名自行填写，30名由访员协助填写）。
Duke-UNC-11问卷中11个条目的组内相关系数，自行填写问卷和访员协助填写问卷均高于0.50；量表的组内相关系数分别为0.92和0.80。因子分析分离出两个子量表，即保密支持（7个条目）和情感支持（4个条目）。社会支持水平低与以下因素显著相关：年龄超过40岁、丧偶或离异、独居、过度使用者、主观健康状况较差、慢性发病率较高、心理健康障碍和家庭功能障碍。多元线性回归方程能够解释社会支持变异性的30%，其中家庭功能（家庭APGAR量表）解释了23.5%，教育程度解释了3.3%，对内部健康控制的认知解释了2%，心理健康解释了1.2%，对疾病易感性/严重性的认知解释了0.3%。
Duke-UNC-11问卷有效且可靠。
