ABSTRACT
Introduction: The Arm Activity Measure was developed to assess active and passive functions of the upper limb in people with unilateral paresis, but a Chinese version is not available and its psychometric properties have not been specifically tested in people with stroke. This study aimed to translate and culturally adapt the Chinese version of the Arm Activity Measure (ArmA-C) and establish its psychometric properties in people with chronic stroke. Methods: The psychometric properties of ArmA-C were determined in 100 people with chronic stroke. Results: The ArmA-C had good test-retest reliability (intraclass correlation coefficients [ICC] = 0.87-0.93; quadratic weighted Kappa coefficients = 0.53-1.00). A floor effect was identified in section A of the ArmA-C. The content validity and internal consistency (Cronbach's alpha coefficients = 0.75-0.95) were good. The construct validity of the ArmA-C was supported by acceptable fit to the two-factor structure model and significant correlations with the Fugl-Meyer Assessment for Upper Extremity score, grip strength, the Wolf Motor Function Test score, the Trail Walking Test completion time, and the Oxford Participation and Activities Questionnaire scores. Conclusions: The ArmA-C is reliable and valid for assessing active and passive functions in people with chronic stroke.
ABSTRACT
The Oxford Participation and Activities Questionnaire was developed for generic use in the assessment of participation and activity levels. However, it is not available in Chinese and has not been tested in the stroke population. The Oxford Participation and Activities Questionnaire was translated into Chinese and culturally adapted. Its psychometric properties were examined in 100 people with stroke. The participation and activity levels of people with stroke and healthy people were also compared. Content validity and internal consistency (Cronbach's α = 0.86-0.91) were excellent. The test-retest reliability (intraclass correlation coefficient = 0.91-0.94) was also satisfactory. The standard error of the measurement was 4.10-5.31, and the minimal detectable change was 11.37-14.71. Convergent and divergent validity were supported by hypothesis testing. The instrument had a five-factor structure without a ceiling effect. Its routine activity and social engagement scores discriminated people with stroke from healthy people. In conclusion, the Chinese version of the Oxford Participation and Activities Questionnaire is reliable and valid for assessing participation and activity levels in the stroke population.

Social support has an important role in stroke rehabilitation. The Multidimensional Scale of Perceived Social Support (MSPSS) is an instrument examining the adequacy of perceived social support. However, the psychometric properties of the Chinese version of MSPSS (MSPSS-C) have not been examined in Chinese people with stroke. This study aimed at investigating the psychometric properties of the MSPSS-C, identifying the correlations between MSPSS-C scores and health-related measures of these people; and examining the differences in the levels of perceived social support between people with and without stroke in Hong Kong using a cohort of 57 community-dwelling people with stroke and 50 age-matched healthy controls. We found that the MSPSS-C subscales demonstrated excellent internal consistency, and a ceiling effect was observed for the family subscale of the MSPSS-C. The total MSPSS-C score had significant weak to moderate correlations with the scores of the concerned variables of interests. Exploratory factor analysis revealed a two-factor structure for the MSPSS-C. People with stroke had lower levels of perceived social support from friends and their significant other than those without stroke. The MSPSS-C is a valid tool for assessing perceived social support among chronic stroke survivors with moderate to very severe motor impairment.
