The psychometric properties of Bickel and Hanson's Perceived Self-Care Agency Questionnaire (PSCAQ) (Hanson, 1981) were examined using a LISREL confirmatory factor analysis approach. Questionnaires were distributed to a convenience sample of 575 noninstitutionalized adults in northwestern Ohio; 462 questionnaires (80%) were returned. Findings indicated that the factor structure of the PSCAQ is significantly different from that described by Bickel (1982) and does not appear to conform to the expected self-care power component structure. These findings call into question the construct validity of the PSCAQ as a measure of self-care agency in non-institutionalized adults. It should be used only with extreme caution, if at all, for testing the self-care deficit theory.
使用LISREL验证性因素分析方法检验了比克尔和汉森的感知自我护理能力问卷（PSCAQ）（汉森，1981年）的心理测量特性。问卷被分发给俄亥俄州西北部575名非机构化成年人的便利样本；462份问卷（80%）被收回。研究结果表明，PSCAQ的因素结构与比克尔（1982年）所描述的显著不同，似乎不符合预期的自我护理能力组成结构。这些发现使人质疑PSCAQ作为非机构化成年人自我护理能力测量工具的结构效度。如果要用于检验自我护理缺陷理论，应极其谨慎地使用，甚至根本不应使用。
