Background: Major Depressive Disorder (MDD) is a highly prevalent, recurrent, and
potentially chronic disorder. Identifying risk factors and underlying mechanisms to inform
preventive and therapeutic interventions is therefore imperative. Emotion regulation is a
proposed factor in the development and maintenance of MDD. The aim of the present
review was to summarize and synthesize research on

strategy use and emotion regulation abilities in adults diagnosed with current and remitted
MDD.
Methods: Seventy-two eligible studies were retrieved from databases through a
systematic literature search. Group differences between individuals with current MDD,
remitted MDD, and healthy controls were calculated using meta-analytic procedures.
Meta-regression analyses investigated potential moderator effects on emotion regulation
difficulties.
Results: Results indicated that individuals with current MDD report higher maladaptive
emotion regulation strategy use for avoidance (Hedges’ g = 1.3), rumination (g = 2.1),
and suppression (g = 1.1) compared to healthy controls. Also, they reported lower
adaptive emotion regulation strategy use for acceptance (g = −1.0), problem solving (g =
−1.0), and reappraisal (g = −0.7). Individuals with current MDD reported limited general
emotion regulation abilities, indicated by higher alexithymia (g = 1.45), lower emotional
awareness (g = −0.95), emotional clarity (g = −1.50) and emotional tolerance (g =
−1.89). Similar results were found in individuals with remitted MDD for avoidance (g =
1.0), rumination (g = 1.1), suppression (g = 0.6), and general emotion regulation abilities.
However, no difference was found between individuals with remitted MDD and healthy
controls for adaptive emotion regulation strategies. Meta-regression analyses suggest
that age of illness onset, comorbid anxiety and duration of remission influence emotion
regulation.
Conclusion: The present review and meta-analysis indicates that individuals with
current and remitted MDD have difficulties with emotion regulation compared to
individuals who have never been depressed. Although depressive symptoms improve,
emotion regulation difficulties may continue, and could be a contributing factor to
relapse. Our findings inform future research on emotion regulation and psychotherapeutic
interventions.
