UNASSIGNED: Prior findings indicate that individuals scoring high on vital exhaustion show a dysfunctional stress response (DSR), that is, reduced @entity701 reactivity and habituation to @entity2673 . The main aim of the present study was to examine whether a DSR may be a vulnerability factor in @entity74 ( @entity2613 ). We examined whether a DSR is present during the early stages of ED, and still is present after recovery. Three groups were studied: 1. Former @entity2613 @entity1 (n=14); 2. @entity1 who during the past 6month had experienced stress at work and had a Shirom-Melamed Burnout Questionnaire (SMBQ) score over 3.75, considered to indicate a pre-stage of @entity2613 (n=17); 3. @entity1 who had not experienced stress at work during the past 6months and had a SMBQ score below 2.75 (n=20). The @entity1 were exposed twice to a virtual version of the Trier Social Stress Test (V-TSST), during which salivary @entity701 samples were collected. In addition, high frequency heart rate variability (HF-HRV), heart rate (HR), t-wave amplitude (TWA), and a-amylase were assessed to examine stress reactivity and habituation in the autonomic nervous system (ANS). The initial analyses showed clear @entity2339 and sympathetic nervous system (SNS) activations in both V-TSST sessions, together with habituation of @entity701 and heart rate in the second session, but without any significant group differences. However, the former @entity2613 @entity1 showed considerable variation in self-reported signs of exhaustion (SMBQ). This led us to assign former @entity2613 @entity1 with lower ratings into the low SMBQ group (LOWS) and those with higher ratings to the high SMBQ group (HIGHS). When repeating the analyses a different picture emerged; the HIGHS showed a lower @entity701 response to the V-TSST than did the LOWS. Both groups' @entity701 response habituated to the second V-TSST session. The ANS responses did not differ between the two groups. Thus, @entity1 in a pre-stage of @entity2613 and unrecovered former @entity2613 @entity1 showed signs of DSR, in contrast to healthy controls and recovered former @entity2613 @entity1 . The results may be interpreted as indicating that DSR in the @entity2270 is present early on in the stress process, but subsides after successful recovery.
