International Journal of Rheumatic Diseases, 05/04/2012
Ng X et al. – In this pilot study, the authors provided preliminary evidence to demonstrate the good test–retest reliability and reasonable construct validity of Scleroderma Health Assessment Questionnaire (S–HAQ) and Systemic Sclerosis Quality of Life scale (SSc–QoL) for use in English and Chinese–speaking SSc patients. This forms the basis for future studies to assess more extensively their psychometric properties.
