Development and validation of a Self-Concept Questionnaire for Hong Kong Chinese adults who have physical disability

Previous research (Tam & Watkins, 1995) provided an understanding of the self-concepts of Hong Kong Chinese adults who have physical disability. Through constructing a hierarchical multidimensional self-concept model for the disabled population, a theoretical basis was established for the development of a questionnaire to measure their self-concepts. Subsequent efforts focused on validating this instrument, the Self-Concept Questionnaire for Physically Disabled Hong Kong Chinese (SCQPD). The results provided evidence that this instrument is psychometrically sound. The scales have satisfactory internal consistency reliability and factor analysis of these scales makes conceptual sense. Some evidence for construct validity is also presented.
