The People with Disability's Perception of Family Support Scale was developed in the Chinese language to enable career counsellors, educators, researchers, and policymakers to assess the perceptions of people with a disability regarding their family support for developing vocational rehabilitation services. This study analysed 515 valid questionnaires. An exploratory factor analysis was conducted in the pilot study with data from 124 participants; confirmatory factor and Rasch analyses were conducted in the main study with data from 391 participants. The six-factor structure had a favourable fit to the observed data and excellent internal consistency (Cronbach's [alpha] = 0.92) and test-retest reliability (0.97), indicating that the scale is a brief yet psychometrically sound measure for evaluating perceptions of family support among people with disability in Chinese populations.
