Impact of Type D Personality on Depression, Anxiety, and Health-related Quality of Life among Coronary Artery Disease Patients: A Systematic Review and Meta-analysis

Purpose: The purpose of this study was to investigate the impact of Type D personality among patients with Coronary Artery Disease (CAD).Methods: Seven databases were searched to conduct a systematic review and meta-analysis.Two reviewers independently searched, selected, extracted, and assessed the studies.The quality of studies was evaluated using the JBI Critical Appraisal Checklist.To estimate the effect size, meta-analysis of the studies was performed using the Comprehensive Meta-Analysis 3.0 program.Results: Of 1,128 publications identified, 31 studies that met the inclusion criteria were used to estimate the effect size of Type D personality.Effect size (Standardized Mean Difference [SMD]) was used in the analyses.Patients with CAD who had Type D personality had higher levels of depression (SMD=0.92;95% Confidecne Interval (CI)=0.74~1.10)and anxiety (SMD=1.19;95% CI=0.81~1.57),but lower levels of physical and mental health-related quality of life (SMD=-0.56;95% CI=-0.75~-0.38;SMD=-0.91;95% CI=-1.10~-0.73).Publication bias was not detected.Conclusion: Type D personality was associated with increased depression and anxiety and impaired health-related quality of life in patients with CAD.Personality and psychosocial risk screening in patients with CAD should be conducted in the clinical setting.
