Development and Preliminary Testing of the Biopsychosocial Prognosis Scale for Coronary Artery Bypass Grafting

The present study attempted to develop a self-report scale called Biopsychosocial Prognosis Scale for Coronary Artery Bypass grafting (BIPROSCAB) that measured patients' prognosis in an integrated manner, a month after they had undergone coronary artery bypass grafting (CABG).

The development and preliminary testing of the psychometric properties of BIPROSCAB followed five phases involving 450 patients in total.

Findings gave rise to a 25-item scale which was subjected to an exploratory factor analysis using principal component analysis with varimax rotation. A 9-factor structure emerged, and the factors were named post-CABG affect state, post-CABG anxiety, post-CABG physical pain, discomfort in surgical sites, worry about return to normalcy, discomfort in the leg, CABG bio-social by-products, constraints in socializing, and infection and interference to routine life. The reliability, validity, and usability of BIPROSCAB were also analyzed.

BIPROSCAB is a reliable, valid, and useful multidimensional self-report scale for measuring and evaluating the impact of medical treatment and psychosocial intervention in patients after CABG.
