ObjectiveTo examine the construct validity of the Participation Measure--3 Domains, 4 Dimensions (PM-3D4D), a multidimensional participation measure developed for use in rehabilitation practice.DesignCross-sectional study.SettingOutpatient rehabilitation programs.ParticipantsRehabilitation patients (n=556, mean age±SD, 61.4±23.6 years; 47% female) participated in the study.InterventionsNot applicable.Main outcome measureThe PM-3D4D is a 19-item measure designed to evaluate participation in three domains: 'Productivity', 'Social', and 'Community' domains across four dimensions: 'Diversity', 'Frequency', 'Desire for change', and 'Difficulty'. Intercorrelations among the four dimensions of the PM-3D4D and correlations between the PM-3D4D and three legacy instruments: the Participation Assessment with Recombined Tools-Objective (PART-O), the Participation Measure for Post-Acute Care (PM-PAC), and the Satisfaction with Life Scale (SWLS), were examined to establish the convergent/divergent validity of the PM-3D4D. Known-group validity was evaluated by comparing PM-3D4D scores across age groups and groups of people classified by functional level.ResultsThe 'Diversity' scale of the PM-3D4D was strongly correlated with the 'Frequency' scale (rs=0.83∼0.96 across the three domains), and these two scales showed moderate to strong correlations with the 'Difficulty' scale (rs=0.42∼0.70) but weak (rs=-0.4∼0) and insignificant correlations with the 'Desire for change' scale. The PM-3D4D 'Frequency' scale and 'Difficulty' scale showed moderate to strong correlations with PART-O and PM-PAC (rs=0.41∼0.82), respectively; and its 'Desire for change' scale had weak correlations with SWLS (rs=-0.32∼-0.18). Significant differences in PM-3D4D scores were found by age and functional level.ConclusionsFindings of this study support the construct validity of the PM-3D4D, providing evidence for using the PM-3D4D to assess rehabilitation patients' participation performance and helping practitioners identify intervention priorities to improve patients' participation outcomes.
