Behavior modification techniques of massed negative practice and relaxation training were applied to separate groups of individuals who had been diagnosed as "bruxers" by multiple criteria. When assessed by an objective index of grinding, neither technique was found to have reduced bruxism significantly. Grinding and state of anxiety scores of bruxers were significantly higher than those of nonbruxing controls. Bruxers did not differ from nonbruxers on trait anxiety measures.
将集中消极练习和放松训练等行为矫正技术应用于通过多种标准被诊断为“磨牙症患者”的不同个体组。当通过磨牙的客观指标进行评估时，发现这两种技术均未显著降低磨牙症。磨牙症患者的磨牙情况和焦虑状态得分显著高于非磨牙症对照组。在特质焦虑测量方面，磨牙症患者与非磨牙症患者没有差异。
