Systematic Review of the Links between Eco-Distress and Mental Health

Although it varied in magnitude, there was a significant positive correlation between eco-distress and mental health impairments. However, type of eco-distress questionnaire did not systematically influence the effect size. The heterogeneity was considerable and could only be partially explained by the moderators used. Future research should focus on the psychometric evaluation of existing instruments, as information on psychometric quality was incomplete for many instruments.
