Record linkage is feasible with non‐identifiable trauma and rehabilitation datasets

Objectives: 1) Describe probabilistic linkage (PL) for road trauma and rehabilitation records in New South Wales (NSW) Australia. 2) Determine the accuracy of linkage for these records.

The psychometric properties of a modified client-centred rehabilitation questionnaire in an Australian population

Abstract Purpose: To identify the face validity of the Client-Centred Rehabilitation Questionnaire (CCRQ) and to determine the internal consistency reliability and factorial validity of a modified CCRQ. Materials and methods: This study was conducted in 2 phases. Phase 1 consisted of 5 focus groups to examine the face validity of the CCRQ, resulting in the development of a modified CCRQ. Phase 2 consisted of a multi-site cross sectional survey, involving 408 rehabilitation inpatients, to examine the internal consistency reliability and factorial validity of the modified CCRQ. Chronbach’s coefficient alpha, composite reliability coefficients, and single factor congeneric models with maximum likelihood confirmatory factor analysis were used. Results: Based on feedback from the focus groups the CCRQ was modified with the word ‘rehabilitation’ replacing ’program’ throughout. The three negatively worded items had poor item-to-total correlations of <0.3. Removing these items resulted in subscale alphas of 0.74–0.86 and composite reliability coefficients of 0.66–0.87. Six of the seven sub-scales had good model fit and the other one had moderate fit following removal of the negatively worded item. Conclusions: This study supports the underlying structure and internal consistency of the modified CCRQ. Implications for Rehabilitation Person-centredness is an important characteristic of effective rehabilitation service delivery that warrants measurement. A modified Client-Centered Rehabilitation Questionnaire has been found to have good face validity, internal consistency reliability and construct validity in an Australian sample of inpatient rehabilitation patients. Use of a modified Client-Centered Rehabilitation Questionnaire incorporating the 7 sub-scales in the original Client-Centered Rehabilitation Questionnaire is supported for use in inpatient rehabilitation. Both sub-scale and item level responses to the modified Client-Centered Rehabilitation Questionnaire provide detailed feedback to rehabilitation service providers looking for opportunities to make their services more person-centred.
