Validation of the English and French versions of the Brief Health Care Climate Questionnaire.

Patient autonomy is a central value in medicine and critical component of adherence to medical advice. This article reports on a validation of the 6-item version of the Health Care Climate Questionnaire (HCCQ), a measure of autonomy support in health care settings, in a sample of 242 melanoma patients. The HCCQ showed excellent internal consistency ( = .91), structural validity (Tucker-Lewis index = .99; comparative fit index = .99; root mean square error of approximation = .06, 90 per cent confidence interval (.00, .11); standardized root mean square residual = .02; (8,  = 235) = 13.99,  = .08) and construct validity (92.31% of hypothesized correlations with other measures confirmed). Acceptable 3-month test-retest reliability was observed ( = .55,  < .001; intraclass correlation coefficient (, 1) = .54,  < .001). The French version was found equivalent to the English version.
