Importance: The Canadian Occupational Performance Measure (COPM) is widely used in clinical practice and research. However, the measurement properties of the COPM were not reviewed using rigorous systematic methodology. Objective: To evaluate the measurement properties of the COPM. Data Sources: MEDLINE, Web of Science, Scopus, OTseeker, and Cochrane Library. Study Selection and Data Collection: We used the updated COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias checklist to evaluate the measurement properties of the COPM reported in relevant studies. Findings: Our search identified 35 articles that reported measurement properties for the COPM with samples that differed in age, country, diagnosis, and disease stage. For content validity, the evidence was inconsistent and of low quality; no studies assessed structural validity. For reliability, the internal consistency was indeterminate and of low quality. One study reported indeterminate and very low quality evidence for cross-cultural validity. According to the evidence reported in these studies, the COPM has inconsistent and moderate reliability, construct validity, and responsiveness and insufficient and high-quality evidence for criterion validity. Conclusions and Relevance: Our review of the evidence using the COSMIN Risk of Bias checklist indicates that the Canadian Occupational Performance Measure lacks high-quality validation. What This Article Adds: High-quality validation of the Canadian Occupational Performance Measure is lacking. Further examination of its measurement properties using updated relevant guidelines is required.

Background: The Canadian Occupational Performance Measure (COPM) is an individualized patient-reported outcome designed to evaluate the self-perceptions of a patient’s occupational performance. Our study aimed to examine the minimal important change (MIC) in inpatients undergoing subacute rehabilitation. The MIC values were calculated using the three different anchor-based analyses with the transition index as an external criterion; the mean change method (MIC_MeanChange), the receiver operating characteristic (MIC_ROC) analysis, and the predictive modeling method adjusted for the proportion of improved patients (MIC_adjust). In this study, the MIC_adjust value was considered as the most valid statistical method. We recruited 100 inpatients with various health conditions from subacute rehabilitation hospitals. Data were collected twice: an initial assessment and a reassessment one month later. The systematic interview format (Five Ws and How) was used for both the initial and second assessments to prevent information bias (response shift). Results: Three patients who indicated deterioration on the transition index were excluded from all analyses, and 97 patients were analyzed in this study. The MIC_adjust values were 2.20 points (95% confidence interval 1.80–2.59) for the COPM performance score and 2.06 points (95% confidence interval 1.73–2.39) for the COPM satisfaction score. The MIC_MeanChange and MIC_ROC values were considered less reasonable to interpret because the proportions of the improved patients subgroup were more than 50% (82.5%). Conclusions: The MIC_adjust value estimates from this study can help detect whether the patients’ perceived occupational performance improved or did not change. The results support the multidisciplinary use of COPM in clinical practice and research on subacute rehabilitation inpatients.

Background: Although various technologies are used to evaluate driving skill, there are some limitations such as the limited range of the monitor and the possible risk of causing cybersickness. The purpose of this study is to investigate differences in the hazard perception and cybersickness experienced between novice and experienced drivers measured in a VR hazard perception test with a head-mounted display (HMD). Methods: The novice (n = 32) and the experienced drivers (n = 36) participated in the hazard perception test through the VR of an HMD. Results: The total number of identified hazards was 1071 in the novice drivers and 1376 in the experienced drivers. Two of the hazards appeared to be only identifiable through the HMD. A chi-square test revealed that experienced drivers were more likely to identify the hazards than the novice drivers (p < 0.05). The novice drivers appeared to identify “hazard prediction of the current behavior of other road users” more than other hazard types, unlike the experienced group. The Simulator Sickness Questionnaire scores indicated no significant difference in the different age or gender groups (p > 0.05). Conclusion: Our results suggest that the VR hazard perception test may be useful for evaluating patients’ driving skills.

Background: Collaboration is an important concept in goal-setting in occupational therapy. However, this concept is not stable due to various definitions. The purpose of this study was to clarify the concept of collaboration in occupational therapy. Method: A scoping review was used to search for all articles related to occupational therapy and collaboration. PubMed, Web of Science, CINAHL, and OT Seeker searches were conducted using predetermined keywords. Three examiners independently reviewed and assessed the quality of each study using Walker and Avant’s concept analysis method. Results: Results of the database searches yielded 1873 studies, 585 of which were deemed eligible to include in this review. Results showed five attributes (“active participation for the common objective”, “existence of something to share”, “matured communication and interaction”, “relationship founded on the respect and trust” and “complementing each other”) and two antecedents and several consequences. Conclusions: Our findings may contribute to collaborative goal-setting and occupational therapy.

This study aimed to clarify the longitudinal goal negotiation and collaboration process of achieving activity- and participation-level goals. We conducted a qualitative study using the trajectory equifinality model. Nine occupational therapists with experience in setting and achieving activity- and participation-level goals were recruited and interviewed about their clients. We identified two phases and four pathways in the setting and attainment process for activity- and participation-level goals. Throughout the longitudinal goal-setting process, when the occupational therapist and client had difficulty discussing activity- and participation-level goals, the therapist respected the client’s expectations, explained the purpose of occupational therapy in detail, and conducted individual face-to-face interviews. When it was difficult to provide work-based interventions, the occupational therapist made flexible use of functional training, elemental movement training, occupation-based practice, and environmental modifications. The results of this study may assist in supporting clients to improve their activity and participation in home rehabilitation.
