The study aimed to investigate the psychosocial predictors of bruxism. The association of various psychosocial factors such as alexithymia, emotional processing, state and trait anxiety, and stress with awake bruxism was analysed.
The study involved 52 volunteers diagnosed with awake bruxism. The toolkit that was used included the Toronto Alexithymia Scale (TAS-20), the Emotional Processing Scale (EPS), the Cohen Perceived Stress Scale (PSS-10), and the State- and Trait-Anxiety Inventory (STAI), with independent individual psychological diagnoses being made for every patient. The results were statistically analysed using IBM SPSS Statistics 24.
The obtained data clearly show that psychological traits-both permanent dispositions (e.g., state anxiety and alexithymia) and temporary states (e.g., trait anxiety, emotional processing deficits, and psychological stress)-are significant determinants of awake bruxism. The percentage of explained variance indicates the presence of other factors as well.
Psychosocial factors such as state anxiety and trait anxiety, alexithymia, and perceived stress are as important as somatic causes in the occurrence and maintenance of awake bruxism. The profile of the obtained data suggests the possibility of preventing or minimizing the symptoms of awake bruxism through properly constructed psychoprophylactic interactions.
本研究旨在探讨磨牙症的心理社会预测因素。分析了各种心理社会因素（如述情障碍、情绪处理、状态和特质焦虑以及压力）与清醒磨牙症的关系。
本研究纳入了 52 名被诊断为清醒磨牙症的志愿者。使用的工具包包括多伦多述情障碍量表（TAS-20）、情绪处理量表（EPS）、科恩感知压力量表（PSS-10）和状态-特质焦虑量表（STAI），对每位患者进行独立的个体心理诊断。使用 IBM SPSS Statistics 24 对结果进行了统计分析。
获得的数据清楚地表明，心理特征——包括永久性特征（如状态焦虑和述情障碍）和暂时性状态（如特质焦虑、情绪处理缺陷和心理压力）——是清醒磨牙症的重要决定因素。解释方差的百分比表明还存在其他因素。
状态焦虑和特质焦虑、述情障碍和感知压力等心理社会因素与躯体原因一样，在清醒磨牙症的发生和维持中同样重要。获得的数据表明，通过适当构建心理预防干预，有可能预防或最小化清醒磨牙症的症状。
