This study evaluates the factor structure and concurrent validity of a measure of self-care, the Denyes Self Care Practice Instrument (DSCPI-90), when used with adults. Three hundred eight participants complete the 18-item DSCPI-90 and a measure of general health status. Data are examined using descriptive statistics, exploratory factor analysis, and correlation. An efficient 12-item, two-factor model is identified. Reducing the number of items from 18 to 12 does not have an untoward effect on either scale reliability or the amount of variance explained. Correlations with a measure of health status are modest, lending validity to the construct of self-care as being distinct from, yet related to, health status. It is concluded that the 12-item version of the DSCPI is reliable and valid when used with adults.
本研究评估了一种自我护理测量工具——德尼斯自我护理实践量表（DSCPI - 90）在用于成年人时的因子结构和同时效度。308名参与者完成了包含18个条目的DSCPI - 90以及一项一般健康状况测量。使用描述性统计、探索性因子分析和相关性分析对数据进行检验。识别出了一个有效的包含12个条目的双因子模型。将条目数量从18个减少到12个对量表信度或所解释的方差量均无不良影响。与健康状况测量的相关性适中，这为自我护理这一结构与健康状况不同但又相关的观点提供了效度支持。研究得出结论，DSCPI的12条目版本在用于成年人时是可靠且有效的。
