Reliability and validity testing of the Chinese version of Self-Efficacy for Managing Symptoms Scale based on patient reported outcome measurement information system among patients with nasopharyngeal carcinoma / 中国实用护理杂志

ABSTRACT

Objective:To translate the Efficacy of Self-Efficacy for Managing Symptoms (SEMSX) based on the Patient-Reported Outcomes Measurement Information System (PROMIS) into Chinese, and to test the reliability and validity of the scale among Chinese patients with nasopharyngeal carcinoma.Methods:The English version of PROMIS-SEMSX was translated into Chinese according to the FACIT translation method. The reliability and validity of the scale were evaluated. From January to April in 2021, the convenient sampling method was adopted to select 205 patients with nasopharyngeal cancer in Zhejiang Cancer Hospital for investigation.Results:The Chinese version of PROMIS-SEMSX scale consisted of 28 items in 4 dimensions, which were consistent with confidence level(with 7 items), symptom management(with 5 items), the impact of symptoms on life(9 items), seeking and understanding support(7 items). The calibration correlation validity was 0.935. The total Cronbach α coefficient of the scale was 0.966, and the half-reliability of the total scale was 0.891. The Cronbach α coefficient of each dimension was 0.910-0.938, and the total retest reliability coefficient of the scale was 0.757.Conclusions:The Chinese version of PROMIS-SEMSX has good reliability and validity in patients with nasopharyngeal carcinoma, and provides a new tool for patients with nasopharyngeal carcinoma to evaluating self-efficacy symptom management.
