Abstract
This research was conducted to revise of the Self-Care Agency Questionnaire (SCAQ). The validity and the reliability of the SCAQ were tested for this purpose. The SCAQ consists of the scale of 29-items, which includes four subscales: a) ability to perform self-care operations, b) ability to adjust one's own physical condition based on personal weaknesses, c) ability to concentrate one's attention on self-care, and d) ability to receive valid support.
The age of subjects ranged from 40 to 65 years. Most of those subjects had been suffering from diabetes, cardiac disease, or hypertension. The construct validity of the SCAQ was tested using factor analysis and the known-groups technique. And there was significant relationship between the SCAQ and the Exercise of Self-Care Agency Scale 35 items version (r=.72, p<.001). The stability of the SCAQ was tested using test-retest reliability (r=.85, p<.001). Internal consistency was also tested, Cronbach's alpha for the SCAQ was. 91.
The validity and the reliability of the SCAQ were supported. The ability to adjust one's own physical condition based on personal weaknesses of the SCAQ were distinctive features as self-care agency's subscale.
