Abstract

PurposeThe purpose of this study is to develop and test the causal relationships between alcohol consumption, social support, illness perception, fatigue and functional status among persons with liver cirrhosis. The hypothesized model was developed based on the theory of unpleasant symptoms.Design/methodology/approachA cross-sectional study was conducted among 400 persons with liver cirrhosis by stratified random sampling. Data were collected at outpatient departments from four public hospitals across three regions in Thailand. Six self-report questionnaires were utilized to collect data from March to August 2020. The developed model was verified via a structural equation modeling analysis.FindingsThe proposed model fit with the empirical data considering from χ2/df = 2.397 (p = 0.061), root mean square error of approximation (RMSEA) = 0.056, comparative fit index (CFI) = 0.985, Tucker–Lewis index (TLI) = 0.981, and standardized root mean square residual (SRMR) = 0.048. The model explained 71.30% of the total variance in functional status. Social support was the most influential factor affecting functional status both directly and indirectly through illness perception. Illness perception had a negative direct effect on functional status and a positive indirect effect on functional status through fatigue. Fatigue had a negative direct effect on functional status. Alcohol consumption was found as the lowest influential factor affecting functional status.Originality/valueThis is the first study that explores the characteristics of functional status among persons with liver cirrhosis comprehensively. A causal relationship among various variables found in this study would shed light as important fundamental data for developing interventions to enhance functional status among this population.
