Purpose:
This study aimed to develop and test the psychometric properties of a Professional Nursing Support Scale for patients with cancer in mainland China.
Methods:
The study was conducted in two phases from January 2017 to January 2020. Phase I involved item generation and developing a preliminary version of Professional Nursing Support Scale through literature review, qualitative interviews, content validity evaluation and a pilot study. Phase II involved psychometric properties testing of the Professional Nursing Support Scale in 700 patients with cancer recruited from four public hospitals in Anhui Province, China.
Results:
A 49-item Professional Nursing Support Scale was finally developed. Exploratory factor analysis showed a four-factor structure of the 49-item Professional Nursing Support Scale, accounting for 56.95% of variance. Cronbach's α ranged from 0.91 to 0.94 for the four subscales. Confirmatory factor analysis further confirmed the best model fit of four-factor structure of the Professional Nursing Support Scale. The Professional Nursing Support Scale also showed an acceptable concurrent validity with Supportive Care Needs Scale short form 34 (r = 0.75, p < 0.001) and Psychological Distress Thermometer (r = 0.39, p < 0.001).
Conclusions:
The Professional Nursing Support Scale is a reliable and valid instrument to assess perceived needs of professional nursing support and support acquisition in relation to the care in Chinese patients with cancer.
