背景：之前发表的一项针对生活在物质使用障碍 (SUD) 康复住房中的大学生的研究结果表明，八个疗程的心率变异性生物反馈 (HRVB) 干预可显着降低渴望。然而，该研究发现，在 HRVB 过程中，参与者之间的渴望变化模式存在明显的差异，值得进一步探索。当前调查的目的是检查人内和人间因素如何对渴望变化产生不同的影响。方法：使用纵向多级建模方法，将时间嵌套在第 1 级人员中，并嵌套在第 2 级人员中。多级变化模型被估计为随着时间的推移，作为年龄、性别、禁欲时间、每日 HRVB 练习、焦虑、抑郁和压力的函数，对渴望轨迹和预测关系进行建模。结果：发现了渴望减少的二次模式，表明一些参与者的渴望减少随着时间的推移而加速。每天进行超过 12 分钟的 HRVB 练习，随着时间的推移，随着年龄的增长，食欲会显着减少。抑郁症状的增加减弱了 HRVB 对渴望的影响。在这项研究中，其他预测因素与渴望没有显着相关。最终模型的真实 R-2 表明，20.5% 的渴望差异是由年龄较大、每日 HRVB > 12 分钟以及人体内抑郁变化来解释的。结论：HRVB 显示出作为一种易于使用、可扩展且具有成本效益的补充性抗渴望干预措施的前景。医疗保健提供者可以通过常规和战略性地使用 HRVB 实践来帮助从 SUD 中恢复的人更好地控制物质渴望。
Background: Previously published findings from a study of university students living in substance use disorder (SUD) recovery housing showed an eight-session heart rate variability biofeedback (HRVB) intervention significantly reduced craving. That study, however, uncovered pronounced inter-participant variability in craving change patterns through the course of HRVB that warranted further exploration. The purpose of the current investigation was to examine how within- and between-person factors may have differentially influenced craving changes.Methods: A longitudinal multilevel modeling approach was used with time at level-1 nested within persons at level-2. Multilevel models of change were estimated to model craving trajectories and predictor relationships over time as a function of age, sex, length of abstinence, daily HRVB practice, anxiety, depression, and stress.Results: A quadratic pattern of craving reductions was found, indicating that craving reductions accelerated over time for some participants. Daily HRVB practice of >12 min and older age significantly enhanced craving reductions over time. Increases in depressive symptoms attenuated the effects of HRVB on craving. The other predictors were not significantly associated with craving in this study. The true R-2 for the final model indicated that 20.5% of the variance in craving was explained by older age, daily HRVB > 12 min, and within-person changes in depression.Conclusions: HRVB shows promise as an accessible, scalable, and cost-effective complementary anti-craving intervention. Healthcare providers may help persons recovering from SUD to better manage substance craving by the routine and strategic use of HRVB practice.
