Development of Survey Instrument
The development of the PARTS/M was included in a project that had a goal of producing 2 measures: one of participation and one of environmental barriers and facilitators to participation. Survey questions were based on qualitative studies of participation of people with mobility impairments and limitations in major life activities (PARTS/M).35 The PARTS/M items were developed by using 15 key informant interviews and 15 focus groups using the ICIDH-2 as a contextual framework.17 In-depth
Reliability
Responses to each survey question for all activities (eg, dressing, vacationing, parenting, working, socializing) and domains (eg, self-care, mobility, domestic life) were examined for internal consistency and stability (table 4). The self-care domain showed the highest internal consistency (.91) followed by the community, social, and civic life domain (.85). The stability (test-retest reliability) values (Pearson r) of all domains were .77 or higher.
The second approach taken to determine the
Discussion
The PARTS/M is a reliable and valid measure of participation in major life activities for people with functional mobility impairments and activity limitations in environments in which they live. By using the ICF as framework, the PARTS/M provides a measure of many components of participation included in existing but separate instruments. This allows the user to assess each subject’s current level of participation that he/she deems to be important and to provide a guide for changes that may help
Conclusions
The PARTS/M can be used to test the concept that disability incorporates not only personal limitations but also the environmental factors that may restrict or facilitate participation in doing activities in lived environments. The PARTS/M provides a measure for extending beyond basic functioning (eg, hearing, seeing, walking) and basic body functions (eg, bowel and bladder control, dressing, grooming) to participation in major life activities (eg, travel, parenting, intimacy, leisure, work)
