Temporomandibular disorders and somatization have shown interrelation in many studies. The physical and psychological factors which contributed to the occurrence and relation of both conditions are yet to be determined.
The personality traits, coping styles and psychological distress of young adults with temporomandibular disorder (TMD) and somatic symptoms were characterized together with the determination of psychological risk factors for TMDs, somatization and combined conditions.
Participants were recruited from university-attending young adults. TMD and somatic symptoms were appraised with the short-form Fonseca Anamnestic Index and Patient Health Questionnaire-15. Psychological variables were assessed with the Big Five Personality Inventory-10, Brief-COPE Inventory and Depression, Anxiety, and Stress Scales-21. Data were evaluated using chi-squared/non-parametric tests and logistic regression analyses (α = .05).
Among the 507 participants (mean age 22.2 ± 1.5 years), 46.4% reported no TMD/somatic symptoms (NS) while 7.5%, 34.5% and 11.6% had TMDs only (TS), somatization only (SS) and combined TMDs-somatization (CS), respectively. Significant differences in conscientiousness (NS > SS), agreeableness (NS, TS > CS; NS > SS), dysfunctional coping, general distress, depression, anxiety and stress (CS ≥ SS > NS) were discerned. Multivariate analyses indicated that the odds of TS were increased by anxiety (OR = 1.10; 95% CI = 1.01-1.21), while the odds of SS/CS were affected by anxiety (OR = 1.15; 95% CI = 1.06-1.25/OR = 1.34; 95% CI = 0.19-1.52) and problem-focused coping (OR = 0.71; 95% CI = 0.56-0.89/OR = 0.55; 95% CI = 0.39-0.78).
Though individuals with TMDs and somatization have dissimilar psychological profiles, anxiety constantly increased their likelihood. Problem-focused coping strategies may help alleviate psychosocial and physical stressors associated with TMDs and somatization.
许多研究表明，颞下颌关节紊乱和躯体化之间存在相互关系。导致这两种情况发生和相互关系的身心因素仍有待确定。
本研究旨在探讨年轻的颞下颌关节紊乱（TMD）患者和躯体症状患者的人格特质、应对方式和心理困扰，确定 TMD、躯体化和合并症的心理危险因素。
参与者来自于在校大学生。使用简化版 Fonseca 病史索引和患者健康问卷-15 评估 TMD 和躯体症状。使用大五人格量表-10、Brief-COPE 量表和抑郁、焦虑和压力量表-21 评估心理变量。采用卡方/非参数检验和逻辑回归分析（α = .05）进行数据分析。
在 507 名参与者中（平均年龄 22.2 ± 1.5 岁），46.4%报告无 TMD/躯体症状（NS），7.5%、34.5%和 11.6%分别为仅有 TMD（TS）、仅有躯体化（SS）和 TMD 与躯体化共存（CS）。在尽责性（NS>SS）、宜人性（NS、TS>CS；NS>SS）、功能失调的应对方式、一般困扰、抑郁、焦虑和压力（CS≥SS>NS）方面存在显著差异。多变量分析表明，焦虑会增加出现 TS 的可能性（OR = 1.10；95%CI = 1.01-1.21），而 SS/CS 的可能性受到焦虑（OR = 1.15；95%CI = 1.06-1.25/OR = 1.34；95%CI = 0.19-1.52）和问题导向应对方式（OR = 0.71；95%CI = 0.56-0.89/OR = 0.55；95%CI = 0.39-0.78）的影响。
尽管 TMD 患者和躯体化患者具有不同的心理特征，但焦虑始终增加了他们的可能性。问题导向的应对策略可能有助于减轻与 TMD 和躯体化相关的心理和生理压力。
