Development and reliability testing of a symptom assessment scale for postoperative patients with adolescent
1Department of Orthopedic, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei Province, China.
Background:
Patients with adolescent idiopathic scoliosis (AIS) often experience pain, fatigue, decreased appetite, anxiety and depression, etc. Previous studies have focused on investigating a single symptom in patients with AIS, ignoring possible synergistic effects between symptoms, or using self-administered questionnaires that have not been scientifically evaluated.
Aims:
To develop a symptom assessment scale for postoperative patients with AIS and test its reliability and validity.
Methods:
Using the symptom experience model as the theoretical framework, we constructed a bank of scale items based on literature review and semi-structured interviews; formed the initial scale after 2 rounds of expert correspondence; and supplemented the descriptive definitions of each item through pre-surveys. To test the reliability of the scale, 175 postoperative AIS patients attending the department of spine and orthopedics in a tertiary hospital in Wuhan city were conveniently selected for a formal survey.
Results:
The scale consisted of 24 items, and 5 common factors were extracted by exploratory factor analysis, with a cumulative variance contribution rate of 67.982 %; the content validity index of the scale was 0.875, and the content validity index of the items was 0.800-1.000; the overall Cronbach's α coefficient of the scale was 0.878, the folding reliability was 0.836, and the retest reliability was 0.947.
Conclusions:
The symptom assessment scale for postoperative patients with AIS has demonstrated adequate reliability and validity, thus serving as a valid instrument for evaluating the postoperative symptom experience of patients with AIS.
