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.
