ABSTRACT Anxiety-related responding to, and recovery from, a 5-min 10% carbon dioxide-enriched air presentation among 80 participants with no history of psychopathology was examined. Half of participants were instructed to suppress challenge-induced emotional responses, whereas their matched counterparts were instructed to observe such responses. Responding from immediately post-challenge through a 10-min recovery period was analyzed as a function of Anxiety Sensitivity-Physical Concerns and experimental condition using individual growth curve modeling. Anxiety Sensitivity-Physical Concerns moderated the effect of suppression only on emotion valence during recovery. In terms of main effects, suppression resulted in increased heart rate during recovery and Anxiety Sensitivity-Physical Concerns was positively associated with post-challenge self-reported anxiety. Results are discussed in terms of the potential role of inhibition-oriented affect regulation processes in the etiology of panic disorder.

    ABSTRACT: Posttraumatic stress disorder (PTSD) may develop as a serious long-term consequence of traumatic experiences, even many years after trauma exposure. The objectives of this study were to examine the prevalence of lifetime and current PTSD as well as to detect the most stressful life events and sociodemographic risk factors of PTSD in a general adult Serbian population. The sample consisted of 640 subjects chosen by random walk technique in five regions of the country. The Mini International Neuropsychiatric Interview 5 revealed an 18.8% prevalence rate of current PTSD and a 32.3% prevalence rate of lifetime PTSD. According to the Life Stressor Checklist-Revised, the bombardment, being expelled from home, siege, and participation in combat were the stressful events most likely to be associated with PTSD. The prevalence of PTSD increased among widows and widowers, divorced persons, unemployed persons, and retired persons. The high level of PTSD a few years after the trauma exposure classifies as a significant health problem that can cause serious consequences for families and the community as a whole.

    ABSTRACT: Emotion regulation (ER) deficits have been linked to symptoms of anxiety in cross-sectional studies. However, the direction of the relationship between ER and anxiety symptom severity (ASS) is unclear. In order to clarify the relationship between ER skills and ASS symptoms, we assessed skills and symptoms in 131 individuals twice over a 5-year interval. Cross-lagged panel analyses were conducted to test whether ER skills were a significant predictor of subsequent ASS or vice versa. Additionally, we explored whether specific ER skills differed in regard to the strength of prospective associations with subsequent ASS. ER skills negatively predicted subsequent ASS over and above the effects of baseline ASS (whereas anxiety symptoms did not predict subsequent ER deficits). Acceptance, tolerance, and willingness to confront had the strongest prospective effects on lower subsequent ASS. General ER skills may play an important role in the development and maintenance of anxiety disorders.
