Stages of psychological change among patients with non-alcoholic fatty liver disease in China: a national cross-sectional study

Abstract

Objectives Non-alcoholic fatty liver disease (NAFLD) is becoming the leading cause of chronic liver disease worldwide. However, treatment of NAFLD is potentially influenced by psychological conditions. Using the simplified version of the University of Rhode Island Change Assessment (URICA-SV) scale, this study aimed to evaluate the stage of psychological change as a prerequisite to refining implementation strategies for psychological change.Design A multicentre cross-sectional survey.Setting Ninety hospitals in China.Participants 5181 patients with NAFLD were included in this study.Outcome measures All patients completed the URICA-SV questionnaire and were assigned to one of the three stages of change (precontemplation, contemplation or action) according to their readiness scores. A stepwise multivariate logistic regression analysis was used to identify independent factors associated with the stage of psychological change.Results A total of 4832 (93.3%) patients were included in the precontemplation stage and only 349 (6.7%) considered making a change or preparing to make one. There were significant differences in gender (Cohen’s d=0.039, p=0.005), age (Cohen’s d=−0.327, p<0.001), waist circumference (Cohen’s d=0.143, p=0.003), alanine transaminase (Cohen’s d=0.347, p=0.001), triglyceride (Cohen’s d=0.351, p=0.002), body mass index (BMI; Cohen’s d=0.056, p<0.001), proportion of hyperlipidaemia (Cohen’s d=0.068, p<0.001) and cardiovascular disease (Cohen’s d=0.032, p=0.029), therapeutic regimen (Cohen’s d=0.136, p<0.001), and Chronic Liver Disease Questionnaire-Non-Alcoholic Fatty Liver Disease overall score (Cohen’s d=−0.420, p<0.001) between patients with NAFLD in the precontemplation stage and those in the contemplation/action stage. Logistic regression identified BMI (HR 0.659, 95% CI 0.469 to 0.928, p=0.017), cardiovascular disease (HR 2.161, 95% CI 1.089 to 4.287, p=0.027) and triglyceride (HR 0.751, 95% CI 0.591 to 0.955, p=0.020) as independent factors predicting psychological change.Conclusions The results demonstrated that very few patients with NAFLD presented psychological condition in the stage of action. Psychological condition was found to be significantly related to BMI, cardiovascular disease and triglyceride factors. Integrated diversity considerations for evaluating psychological change are necessary.
