Efficacy of expressive writing versus positive writing in different populations: Systematic review and meta-analysis

This systematic review and meta-analysis investigates the comparative efficacy of expressive writing (EW) and positive writing (PW) across different populations. EW, a classic therapeutic technique, focuses on deep emotional expression regarding traumatic or stressful events. In contrast, PW, a more recent intervention, guides participants to reflect on positive emotions, goals, and strengths. The researchers synthesized data from 24 randomized controlled trials (RCTs) involving 1,558 participants to determine which method better supports psychological health and cognitive processing.

The analysis revealed distinct psychological benefits based on the population type. For the general population, PW outperformed EW in improving mood and fostered more favorable changes in cognitive mechanisms. For individuals diagnosed with health conditions (patients), while PW remained more conducive to generating positive emotions, EW was superior in stimulating cognitive change. The researchers suggest that the difficulty and emotional intensity inherent in EW may serve as a deeper cognitive exercise for those dealing with specific health challenges, whereas PW provides more immediate relief and mood regulation for lower-stress populations like caregivers or healthy students.

The study suggests that nursing staff and clinicians should adopt a targeted approach when assigning writing tasks. Rather than assuming that traditional expressive writing is the standard tool for all scenarios, clinicians should consider the specific goals of the intervention. PW may be better suited for routine mental health support in non-clinical settings, whereas EW could be a more rigorous tool for helping patients reframe their narratives during recovery from illness.
