PurposeTo determine the factorial validity, internal consistency, criterion-related and concurrent validity of the Perception of Quality of Rehabilitation Services – Montreal (PQRS-Montreal) questionnaire for persons receiving traumatic brain injury (TBI) rehabilitation services.DesignCross-sectional study.SettingSeventeen facilities providing acute care and intensive inpatient and outpatient TBI adult rehabilitation.ParticipantsFive-hundred thirty adults (GCS  =  3–15; mean age  =  41.5 ± 16.9 years) who received rehabilitation were administered the questionnaire during an interview near time of discharge. Subjects responded to the 61 PQRS-Montreal items (five-point scale of agreement) and to the Client Satisfaction Question (CSQ8).ResultsExploratory and confirmatory factor analyses identified three potential subscales (one- and two-factor solutions) explaining 26.1–41% of the variance (ecological approach, quality of team, service organization). The subscales’ internal structures were interpretable and their internal consistency varied from 0.51 to 0.90 (Cronbach’s α). Rehabilitation phase significantly and positively impacted factor scores and all factor scores were significantly and moderately correlated with CSQ8 scores.ConclusionsThe PQRS-Montreal possesses adequate psychometric properties supporting its use as a valid tool to measure patients’ perception of the quality of TBI rehabilitation services. This tool could help guide the development and monitoring of TBI rehabilitation service delivery.Implications for RehabilitationThe importance of measuring and monitoring quality of care is increasingly important in rehabilitation.Using the experiences and perceptions of care of service users is a valid way of assessing the quality of rehabilitation services.The PQRS-Montreal has adequate psychometric properties supporting its use as a valid tool to measure patients’ perception of the quality of TBI rehabilitation services.This tool could help guide the development and monitoring of TBI rehabilitation service delivery.

Primary objective: To examine relationships between classical measures of executive functions (EF) and indices of traumatic brain injury (TBI) severity with the IADL Profile, a new performance-based measure of independence in instrumental activities of daily living (IADL) based on EF. This study hypothesized the presence of correlations between classical tests of EF and the IADL Profile, as the latter aims to establish whether the subject's main difficulties pertain to goal formulation, planning, carrying out the task and/or attaining the initial task goal; all important components of EF. Methods and procedures: One hundred subjects with a moderate/severe TBI aged 16-65 years (convenience sample) were recruited. Subjects were tested with the IADL Profile and three measures of EF within their home environment. Data was analysed using Pearson correlations, t-tests and multiple stepwise regressions. Results: Post-traumatic amnesia and working memory emerged as the major determinants of IADL Profile scores. Together, indices of injury severity, measures of EF, education, age and environmental factors accounted for 12-28% of the variance in IADL Profile scores. Conclusions: This study has shown that the IADL Profile's non-structured approach permits the observation of a broad range of behaviours related to EF deficits and thus provides a closer approximation of the person's independence in IADL. Further study is required to demonstrate the IADL Profile's ability to inform more targeted treatment interventions. [ABSTRACT FROM AUTHOR]
