Brief Summary:

The purpose of this study is to evaluate the potential benefit of targeting patients' expectations before coronary artery bypass graft surgery through a brief psychoeducational intervention.

Condition or disease	Intervention/treatment	Phase
Coronary Artery Bypass Graft Surgery (CABG); Patients' Expectations; Coronary Heart Disease	Behavioral: Expectation Manipulation Intervention; Behavioral: Supportive Therapy	Phase 2

Detailed Description:

Coronary artery bypass graft surgery (CABG) is an extremely invasive medical intervention.It is postulated that even under these conditions, treatment outcome is substantially determined by non-specific effects, e.g. patient's expectation. Targeting patients' expectations at an early stage might have potential to optimize outcomes after cardiac surgery. The purpose of this research project is to optimize patients' outcome expectations before undergoing cardiac surgery through a brief psycho-educational program. Using a randomized controlled design, 180 patients who are scheduled to undergo elective CABG are randomly assigned either to standard medical information alone, or to an additional expectation manipulation intervention (EMI) during the two weeks before surgery, or to an attention-control group ("supportive therapy"). The main goal is to enhance positive expectations (surgery 'non-specific effects') about favorable outcome through EMI, about coping abilities to deal with adverse events, and to reduce negative expectations and misconceptions. Assessment takes place before and after EMI, 10 days after surgery and 6 months later; same assessment points are used for the 2 control conditions. Primary outcome is disability, which has been shown to be strongly determined by patient's expectation in previous studies. Moreover, psychological and biological predictors and mediators of treatment success are analyzed. A positive result for this expectation intervention would have major implications for clinical practice. In order to optimize treatment outcome, it is not only necessary to improve the treatment-specific procedures (e.g., cardiac surgery) but also to address non-specific factors such as patients' expectations.

Arms and Interventions

Arm	Intervention/treatment
No Intervention: Standard Medical Care; Patients receive standard treatment protocol for Coronary Artery Bypass Graft Surgery
Active Comparator: Attention Control Group; In addition to standard medical care patients receive a comparable amount of therapist´s attention (common and unspecific factors = supportive therapy) to the intervention group, without targeting patients' expectations.	Behavioral: Supportive Therapy; Supportive therapy employs common factors such as elicitation of affect, reflective listening, feeling understood, but provides no explicit theoretical formulation to the patient. Supportive therapy thus provides a control condition for common factors and therapist attention but lacks the specific intervention part. It will be delivered in the same frequency and at the same time points as the Expectation Manipulation Intervention (2 individual sessions, 2 phone calls).
Experimental: Expectation Manipulation Intervention; In addition to standard medical care patients' expectations prior to surgery are targeted in a brief psycho-educational intervention.	Behavioral: Expectation Manipulation Intervention; The Expectation Manipulation Intervention targets patients' expectations prior to surgery (2 individual sessions, 2 phone calls). Main goal is to enhance positive outcome expectancies, as well as to improve patients' control expectations about possible side effects of the surgery and about their personal management of their coronary heart disease. Further EMI tries to correct dysfunctional beliefs about the coronary heart disease and tries to minimize fears about expected negative consequences.
