Measuring Health Literacy in Primary Healthcare: Adaptation and Validation of a French-Language Version of the Brief Health Literacy Screening among Patients with Chronic Conditions Seen in Primary Care

Background: The Brief Health Literacy Screening (BHLS) is a short self-report instrument developed to identify patients with inadequate health literacy. This study aimed to translate the BHLS into French Canadian (BHLS-FCv) and to evaluate its psychometric properties among patients with chronic conditions in primary care.

Methods: The BHLS was translated into French using the Hawkins and Osborne's method. Content validity was evaluated through cognitive interviews. A validation study of the BHLS-FCv was conducted in two primary care clinics in the province of Quebec (Canada) among adult patients with chronic conditions. Psychometric properties evaluated included: internal consistency (Cronbach's alpha); test-retest reliability (intraclass correlation coefficient); and concurrent validity (Spearman's correlations with the Health Literacy Questionnaire (HLQ)).

Results: 178 participants completed the questionnaire at baseline and 47 completed the questionnaire two weeks later over the telephone. The average score was 13.3. Cronbach's alpha for internal consistency was 0.77. The intraclass correlation coefficient for test-retest reliability was 0.69 (95% confidence interval: 0.45-0.83). Concurrent validity with Spearman's correlation coefficient with three subscales of HLQ ranged from 0.28 to 0.58.

Conclusions: The BHLS-FCv demonstrated acceptable psychometric properties and could be used in a population with chronic conditions in primary care.
