Objective This study aims to develop a scale to measure the worry level of patients who will undergo gastrointestinal (GI) endoscopy with deep sedation, and to provide scientific references to alleviate their worries.
Method Based on literature review, panel discussion, patient interview and expert consultation, we developed the first version of the scale. After two pre-investigations, the formal version of the scale was formed, and the reliability and validity were tested on 1389 respondents. Reliability was assessed by Cronbach's alpha. Construct validity was tested by confirmatory factor analysis (CFA) and the Spearman correlations analysis.
Results The scale was composed of four dimensions: financial and time costs, sedation, examination, and psychology. It has 15 items. Reliability and validity were acceptable. The Cronbach's alpha of the whole scale was 0.959 and all the factor loadings were > 0.50. The Spearman correlations of the inter-dimensions ranged from 0.614 to 0.836, and the correlation coefficients between the dimensions and the total score were 0.795 to 0.957. The correlation coefficient between the total scale score and the APAIS was 0.833.
Conclusions This scale has good validity and reliability, which is useful for physicians and medical institutions to take appropriate measures to reduce patients' worries.
