Fifty adult coronary artery bypass graft surgery patients were randomly assigned to preadmission self-instruction or posthospital admission instruction of therapeutic exercises (e.g., coughing). Self-instructed subjects reported higher positive mood scores, performed correctly significantly more exercise behaviors, and required less teaching time following hospital admission. Postoperatively, no group differences were found on mood states, physical activity, analgesic use, or length of hospital stay. Both groups, however, tended to use less pain medication than that reported by other researchers and experience shorter hospital stays than that assigned under the Diagnostic Related Groups prescription.
50名接受成人冠状动脉搭桥手术的患者被随机分为两组，一组在入院前接受自我指导，另一组在入院后接受治疗性锻炼（如咳嗽）指导。自我指导组的受试者报告了更高的积极情绪得分，正确执行的锻炼行为显著更多，且入院后所需的教学时间更少。术后，在情绪状态、身体活动、止痛药物使用或住院时间方面未发现组间差异。然而，两组使用的止痛药物都比其他研究人员报告的要少，住院时间也比诊断相关组规定的要短。
