Validation of the Chinese Non-pharmacological Therapy Experience Scale in persons with intellectual disability.

ABSTRACT: Aim:To validate the 4- and 7-point Chinese Non-pharmacological Therapy Experience Scales and test the psychometric properties of the scales on persons with intellectual disability. Design:A validation study. Methods:Sixty-seven persons with intellectual disability were recruited from six hostels or centres for persons with intellectual disability in Hong Kong. A total of 1,163 and 1,161 observations were collected by the trained observers with the 4-point and 7-point scales, respectively. The floor and ceiling effects, inter-rater reliability, internal consistency, responsiveness of both scales and the scale equivalence were examined. Results:The Cronbach's ? of the 4- and 7-point scales was .762 and .797, respectively. The correlation between the two scales was 0.906. The inter-rater reliability of the 4- and 7-point scales was 0.774 and 0.835, respectively. Neither scale had the floor or ceiling effects. The effect size of the 7-point scale was consistently higher than that of the 4-point scale.
