Comparing the effectiveness of mind–body practices (MBPs) and various psychological methods on occupational stress among healthcare workers: a network meta-analysis of randomized controlled trials

Abstract

Objectives: The purpose of this study is to compare the efficacy of mind–body practices (MBPs) and multiple psychological methods, and identify the optimal method for relieving work-related stress among healthcare workers (HCWs) by network meta-analysis (NMA). Methods: We applied six electronic databases, namely PubMed, Web of Science, Embase, PsycINFO, Cochrane, and Chinese National Knowledge Infrastructure to identify relevant RCTs from inception to September 16, 2023, and implemented a search strategy based on the PICOS principles. Data selection, extraction, and analysis of bias were carried out independently and in duplicate by separate researchers. State 16.0 was used to conduct NMA for comparing the effectiveness of various therapies. Results: We identified 23 studies including MBPs and three different psychological therapies, namely mindfulness-related therapy (MRT), psychoeducational therapy (PT), and comprehensive therapy (CT), which were divided into eleven specific techniques, namely yoga, meditation techniques (MT), Qigong, muscle relaxation(MR), biofeedback therapy (BT), mindfulness-based interventions (MBIs), modified mindfulness-based stress reduction (MBSR-M), mindfulness-based interventions combined with others (MBIs-C), mindfulness-based awareness(MBA), PT and CT. Our NMA results of MBPs and three psychological therapies showed MBPs (SMD = -0.90, CrI:-1.26, -0.05, SUCRA = 99%) were effective for occupational stress in HCWs, followed by MRT(SMD = -0.48, CrI:-0.87, -0.08, SUCRA = 66.5%). NMA results of eleven specific techniques showed yoga (SMD = 1.36, CrI:0.91, 1.81, SUCRA = 97.5%) was the most effective technique in relieving the stress of HCWs, followed by MR (SMD = 1.36, CrI:0.91, 1.81, SUCRA = 87.3%). Conclusions: Our study suggested MBPs may be the most effective intervention to improve the occupational stress of HCWs. Furthermore, yoga is likely to be the most optimal of MBPs. Hospital managers should attach importance to yoga in addressing occupational stress among medical workers.
