Psychometric properties of the Role Checklist for Spanish-speaking stroke survivors

The Role Checklist is broadly used to assess perceived role participation. Although stroke survivors often experience decreased participation, its reliability has not been evaluated for Spanish-speaking individuals with stroke.

To evaluate the psychometric properties of the Role Checklist in Spanish-speaking individuals with stroke.

Validation study.

Randomly selected public primary care centres.

179 participants with stroke.

Internal consistency was analysed using Cronbach's alpha and item-total correlations. Test-retest and inter-rater reliability were evaluated with the intraclass correlation coefficient (ICC). Measurement precision was examined by calculating the SE of measurement (SEM) and the minimum detectable change (MDC) 95% CI. Floor and ceiling effects were assessed by calculating the proportion of participants who achieved the minimum and maximum possible scores.

The 'role participation' subscale showed a Cronbach's alpha of 0.73 (95% CI 0.57 to 0.74) and the 'assigned value' subscale of 0.45 (95% CI 0.33 to 0.57). All item-total correlations for the items within the 'assigned value' subscale were significant. Test-retest analysis showed ICC values >0.84, and inter-rater reliability showed ICC values >0.99 for role participation and assigned value. The SEM estimates were 1.43 for the role participation subscale and 0.88 for the value attributed to the total number of roles subscale. MDC₉₅ values were 3.96 and 2.43 for these subscales, respectively. No floor or ceiling effects were observed.

The Role Checklist exhibited acceptable internal consistency, temporal stability and interobserver reliability.
