A mean score was calculated for each patient.The secondary end points of the study the effectiveness of the interventions on clinical outcomes, such as breast-conserving surgery rates, the concordance of Navya-PPT–reported preference with the final surgery received by the patient, and the effect of Navya-PPT on DCS score stratified by other psychological indices. Additional psychological scales, including API-DM, TEGR, and caregiving, were also measured on a 1 to 5 Likert scale. The internal reliability of the psychological scales were measured by Cronbach α.
