While clinical factors are routinely considered in management, psychological drivers, such as illness perception, health-related anxiety, and behavioral self-efficacy, are underexplored. This study aimed to evaluate whether these psychological factors are associated with successful weight loss adherence in patients with MASLD. Methods: We conducted a retrospective cohort study of adults with radiologically or biopsy-confirmed MASLD seen at the outpatient departments of Bahrain government hospitals between January and December 2024. Inclusion criteria were BMI ≥30 and completion of standardized psychological assessments: the Brief Illness Perception Questionnaire (B-IPQ), Generalized Anxiety Disorder-7 scale (GAD-7), and Weight Efficacy Lifestyle Questionnaire (WEL). Patients on weight loss medications, including GLP-1 receptor agonists, were excluded. Patients were stratified into adherent (≥5% weight loss) and non-adherent (< 5%) groups. Multivariate logistic regression identified independent psychological predictors of adherence, adjusting for age, sex, diabetes, and ALT. Results: A total of 268 patients met the inclusion criteria. The cohort had a mean age of 46.7 ± 10.9 years; 53% were female and 64% had type 2 diabetes. At 12 months, 29.1% (n=78) achieved ≥5% weight loss. Higher illness perception scores (B-IPQ ≥6) were independently associated with adherence (aOR 2.41; p< 0.001), as were higher self-efficacy scores (WEL, aOR 1.92; p=0.01). A U-shaped relationship emerged between anxiety and adherence: moderate GAD-7 scores (5–9) showed highest adherence (42%), while both low (< 5) and high (≥15) scores were associated with lower adherence (25% and 18%). Patients perceiving MASLD as non-serious were less likely to lose weight, while those concerned about liver progression were more engaged in lifestyle changes. Discussion: Psychological factors, especially illness perception and moderate health-related anxiety, significantly influence adherence to weight loss in MASLD. Routine assessment of patient beliefs and behavioral readiness may help tailor interventions and improve outcomes in this increasingly prevalent disease.
