Psychologic factors and oral lichen planus. A psychometric evaluation of 100 cases.
OBJECTIVE
The purpose of this study was to analyze the importance of psychologic factors in patients with oral lichen planus, and attempts were made to identify possible personality features characteristic of patients with oral lichen planus.


METHODS
The study involved 100 patients with oral lichen planus (group 1) and 50 control subjects (group 2). We applied the following psychometric tests to both groups: Spielberger State-Trait Anxiety Inventory, Cattell Personality Questionnaire 16PF, Hassanyeh Rating of Anxiety-Depression-Vulnerability, Beck Depression Inventory, Raskin Depression Screen, and Covi Anxiety Screen.


RESULTS
The patients with oral lichen planus were found to exhibit greater anxiety, as reflected by statistically significant scores with the anxiety tests that were used (Spielberger State-Trait Anxiety Inventory, Cattell Personality Questionnaire 16PF, Hassanyeh Rating of Anxiety-Depression-Vulnerability, and Covi Anxiety Screen). The patients with oral lichen planus likewise exhibited greater depression than the controls in all 3 depression tests applied (Beck Depression Inventory, Hassanyeh Rating of Anxiety-Depression-Vulnerability, and Raskin Depression Screen) and were more vulnerable to psychic disorders on the basis of the PD subscales (vulnerability) of the Hassanyeh questionnaire. Three features (conformity to the group, astuteness, and rebelliousness) defined the personalities of our patients with oral lichen planus, according to the Cattell 16PF questionnaire. Finally, those patients with erosive lichen planus exhibited higher depression scores than patients with nonerosive lichen planus.


CONCLUSIONS
Despite the higher anxiety scores observed in patients with oral lichen planus, it was not established that the observed psychologic alterations constitute a direct etiologic factor of oral lichen planus; nor was it established that such alterations are a consequence of oral lichen planus and its lesions.
