Summary of Participation and Activity Limitation Survey (PALS) 2001 Disability Scale SCORES A disability index was constructed using all questions for each type of disability

SCORES A disability index was constructed using all questions for each type of disability in the PALS 2001 questionnaire. Points were assigned to each question based on severity, the maximum score being given for someone who is totally disabled in all area. For each type of disability, there are essentially two types of questions: intensity and frequency. Some intensity questions are asked in different contexts. In this case, the mean score is used to measure intensity. The product of frequency and intensity was used to measure severity for each disability type.
