Abstract
Background To translate the English version of supportive care needs scale of head and neck cancer patients (SCNS-HNC) questionnaire into Mandarin (Simplified), and to test reliability and validity. Methods The With authorization of the English version scale were obtained from Professor Irma M. Verdonck-de Leeuw who worked at VU University Medical Center of Cancer Center Amsterdam (CCA), in the Netherlands. The Mandarin (Simplified) version of the SCNS-HNC scale was developed by translation, back-translation and cultural adaptation. The Mandarin (Simplified) version of Supportive Care Needs Survey Short-Form (SCNS-SF34) and SCNS-HNC scales were used to measure 206 patients with head and neck cancer in a upper first-class hospital in Chengdu. Among them, 51 patients were re-tested 2 or 3 days after the first survey. The internal consistency of the scale was evaluated by Cronbach's alpha coefficient, the retest reliability of the scale was evaluated by retest correlation coefficient r, the structural validity of the scale was evaluated by exploratory factor analysis, and the ceiling and floor effects of the scale were evaluated. Item-domain correlation analysis was used to evaluate the collective validity and differential validity of the scale. Results The Mandarin (Simplified) version of SCNS-HNC had Cronbach's alpha coefficients of more than 0.700 (0.737 ≤ 0.962)for the all of the domians. Except for the psychological demand dimension of SCNS-SF34 scale, the retest reliability in other fields was more than 0.8. Three common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 64.39%. The correlation coefficient of all items in Mandarin (Simplified) version of SCNS-SF34and SCNS-HNC with their own domians were higher than those with otherdomians. Conclusion The Mandarin (Simplified) of SCNS-HNC demonstrates satisfactory reliability and validity, which is available for measurement of the supportive care needs of Chinese patients with head and neck cancer.Clinical registration number: ChiCTR1900026635
