[Distinction between anxiety state/trait in general practice: a descriptive study].

Abstract

State-anxiety has been defined as a transitory emotional response involving unpleasant feelings of tension and apprehensive thoughts. Trait-anxiety, on the other hand, has been defined as a personality trait referring to individual differences in the likelihood that a person would experience state anxiety in a stressful situation. The aim of the present study was to assess trait and state-anxiety in a population of patients consulting physicians for anxious complaints. Thus, patients who stopped the benzodiazepine (BZD) treatment after three months and those who continued it for six months were compared. Included patients were evaluated at inclusion (D0), after three months (M3) and after six months (M6). The investigator filled the Covi anxiety scale, the Raskin depression scale and a CGI; patients were asked to fill the Spielberger state/trait-anxiety questionnaire. 1,112 patients have been included, 48% considered their anxiety as chronic, 50% said the evolution was progressive, 87% considered it resulting of a trigger factor, 69% received a benzodiazepine (BZD) treatment. At D0: Covi anxiety score was 5.3 +/- 2.3 points, STAI I (state-anxiety) score was 57.4 +/- 12.2 points and STAI II (trait-anxiety) score was 52.7 +/- 10.2 points. At M3, all scores decreased, and 85% were considered as ameliorated, but differences were significant (p = 0.0001) at M6. When comparing at D0 patients who stopped BZD treatment at M3 and those who continued it, some differences appeared. In fact subjects who stopped the treatment had lower score at the STAI II, presented significantly less flushes (p = 0.01), less tremor (p = 0.04) and less feverishness (p = 0.05). Their score at Covi tended to be lower (p = 0.11). The severity of the disease, evaluated with the CGI, was also lower for the patients who stopped the BZD treatment. The trait-anxiety appeared as a good predictor of the efficacy of the BZD treatment. In fact, the trait-anxiety refers to a tendency to be anxious and higher anxiety necessitates longer treatment. The treatment response was less important in the patients who continued the treatment at M3, indicating the presence of residual anxiety in these patients.
