Fatigue characteristics of included studies.

Chronic physical conditions (CPCs) are conditions that persist for long periods and may not have a cure. Fatigue is a common symptom experienced by people living with CPCs. Mind-body internet and mobile-based interventions (IMIs) offer an accessible management strategy. The objective of this review was to assess the impact of mind-body IMIs on fatigue symptoms in adults with CPCs. Six databases were searched from inception to July 2024. Inclusion required randomized controlled trials (RCTs) of mind-body IMIs in adults (≥ 18) with CPCs that assessed fatigue pre-and post-intervention using self-report questionnaires. The primary outcome was the standardized mean fatigue change scores (Hedges’ g). Sub-group analyses were conducted on CPC type, mind-body technique, fatigue questionnaire, and personnel support level. Meta-regression was performed on IMI length and age. Study quality was assessed using the Cochrane Risk of Bias 2.0 tool. The search retrieved 5239 studies. Seventeen studies met inclusion criteria: 47% neurological (n = 8), 29% cancer (n = 5), and 24% autoimmune (n = 4). Seven studies (41%) included cognitive behavioural therapy (CBT), seven used CBT combined with non-CBT techniques, and three employed non-CBT techniques. Mind-body IMIs led to significant reductions in fatigue (SMD = -0.74 [-1.09, -0.39]; p
