This study aimed to analyze the transferability of non-invasive brain stimulation (NIBS) interventions in individuals with major depressive disorder (MDD) based on the FIELD model (Function, Implementation, Ecology, Level, and Duration), encompassing function, implement, ecology, level, and duration. A systematic search of electronic databases yielded a total of 21 eligible studies, comprising 12 transcranial direct current stimulation (tDCS) and 9 transcranial magnetic stimulation (TMS) trials, involving 1029 individuals with MDD. The meta-analysis of effect sizes revealed positive transfer effects across all domains of the FIELD model, suggesting that NIBS interventions have potential efficacy in improving various facets of MDD. The subgroup analysis highlighted that bilateral dlPFC stimulation exhibited the highest effect size for transferability, indicating greater transferability for rTMS, a higher dose of stimulation, and the integration of additional interventions. Additionally, the study discusses the implications of bilateral dorsolateral prefrontal cortex (dlPFC) stimulation and the integration of complementary therapies for optimizing treatment efficacy.
