What this study supports

Supports the claim that change within writing conditions was small for posttraumatic stress and negligible to small for growth and quality of life, and larger in studies requiring a PTSD diagnosis. Pools only the experimental arms, without control comparisons, so it is graded D and cannot separate writing effects from natural change.

Who was studied
Experimental conditions of expressive writing studies measuring posttraumatic stress, posttraumatic growth and quality of life.
Design
Meta-analysis
Level of evidence
Cross-sectional, observational, qualitative work and narrative reviews.

Claims that rest on it

Each claim states what the site asserts, at what strength, and with what caveat.

EmpiricalLevel DConfidence LOW

A meta-analysis of change within expressive writing conditions found small effects on posttraumatic stress and negligible to small effects on growth and quality of life; without control comparisons it cannot show that writing treats posttraumatic stress disorder.

Scope
Experimental arms of studies measuring posttraumatic stress, growth and quality of life.
Caveat
Change within one arm includes natural recovery and regression to the mean.
