Correlates between temporomandibular disorder severity, emotional distress, and eudaimonic well-being among young adults.

OBJECTIVES

This study examined the correlates between severity of temporomandibular disorders (TMDs), emotional distress, and eudaimonic well-being.

SUBJECTS AND

METHODS

TMD severity, negative emotions, and eudaimonia were assessed with the Fonseca Anamnestic Index (FAI), Depression, Anxiety, Stress Scales-21 (DASS-21), and Psychological Well-being Scale-18 (PWBS-18) in a cohort of community young adults. Statistical evaluations were done with non-parametric tests/correlation and multivariate regression analyses (α = 0.05).

RESULTS

Amongst the 873 participants (mean age 19.8 ± 1.66 years), 40.7%, 49.0%, and 10.3% had no (NT), mild (MT), and moderate-to-severe (ST) TMD, respectively. Significant differences in total-DASS, depression, anxiety, and stress were ST ≥ MT > NT. Significant variances in total-PWSB and self-acceptance were NT > MT > ST while that for environmental mastery, positive relations, and purpose in life were NT > MT, ST. An inverse relationship was discerned between total-DASS and total-PWBS (correlation coefficient = -0.54). The prospect of ST was increased by anxiety but reduced by positive relations and self-acceptance.

CONCLUSIONS

Young adults with mild and moderate-to-severe TMD experienced substantially higher emotional distress and lower eudaimonia than those with no TMD. As emotional distress and eudaimonic well-being are interrelated, positive psychological interventions may be beneficial for managing TMD-related psychosocial disabilities.
