OBJECTIVE: Patients with an implantable cardioverter defibrillator (ICD) and co-morbid depression are at greater risk of poor quality of life and premature death. We examined if treatment expectations predict depressive symptoms 12months post implant.
METHODS: First-time implant patients from the WEBCARE study (n=177; 83.1% men) completed the EXPECTations towards ICD therapy questionnaire and the Type D Scale at baseline, and the Patient Health Questionnaire at baseline and 12months.
RESULTS: Using hierarchical linear regression with 3 models, we identified the following independent predictors of 12-months depressive symptoms: Model 1: Negative treatment expectations (β=0.202; p=0.020) and baseline depression (β=0.376; p<0.0001). Model 2: Baseline depression (β=0.350; p<0.0001) and Type D personality (β=0.162; p=0.042); negative treatment expectations was borderline significant (β=0.169; p=0.051). Model 3: Baseline depression (β=0.353; p<0.0001) and negative treatment expectations (β=0.180; p=0.043); Type D personality was not significant (β=0.150; p=0.067), adjusting for positive treatment expectations, heart failure, sex, and shocks during follow-up. The models accounted for 22.2%, 24.1%, and 23.3% of the variance in 12-months depressive symptoms, respectively.
CONCLUSION: Further research is warranted to explore the role of treatment expectations at the time of implant and its overlap with personality as a determinant of depression in patients with an ICD.
