Role Checklist: The Reliability and Validity Study for Taiwanese Psychiatric Patients

Abstract

We play many roles in our lives. Our spaces and times are arranged and occupational behaviors are organized according to these role. Researchers proposed that cognitive, emotional impairments and restricted learning experience might limit people to practice various roles. Thus, it is necessary to understand client's roles in relation to his or her context for occupational therapists. Occupational therapists found that the test results provide practical information to facilitate clients' motivation in participating the treatment program and their self-awareness.

The purpose of the study is to examine the reliability and construct validity of the Role Checklist for Taiwanese clients. Twenty-nine clients were recruited for reliability study from a psychosomatic unit of a university-affiliated hospital in Taiwan. The diagnoses include mood disorders (55.2%), neurotic, stress-related and somatoform disorders (34.4%), and others (10.3%). All clients were tested and retested during one-week interval. Kappa statistics from SAS computer program were used for analyses. The validity study included 229 clients from the same unit as above. The diagnoses include mood disorders (62.9%); neurotic, stress-related and somatoform disorders (7.0%); Schizophrenia (2.6%), and others (21.4%). Rasch measurement model was used to analyze construct validity through BIOSTEPS computer program.

Kappa values varied from 0.30 to 0.52 for test-retest reliability study. Eighty percents of these values were at the acceptable level. Rasch analysis indicated that the Role Checklist encompasses a uni-dimensional construct. The three most valued roles were ‘value of being a family member', 'value of being a friend', and 'value of being a caregiver'. Value of organization member role was the least valued role among these subjects. The internal consistency is high as demonstrated by high item separation reliability index. The role checklist was supported of its test-retest reliability as well as construct validity of the value items.
