Abstract [sv]

Målet med den här studien var tvåfaldigt. För det första, studien eftersökte att validera tidigare fynd som har visat att stress exposure training (SET) ökar prestationsförmåga och minskar stress under stressamma uppgifter. De ångestrelaterade personlighetsmåtten Neuroticism och intolerance of uncertainty användes för att undersöka om dessa mått uppvisar individuella skillnader i hur effektivt SET är. Testet i studien var en visuell diskrimineringsuppgift som sammanföll med ljudbaserade stressorer. Prestation, uppskattad stress, och elektrodermal aktivitet mättes. Genomsnittsvärden jämfördes före och efter SET, vilket visade ökad prestation, minskad upplevd stress, och inga förändringar i elektrodermal aktivitet. Individuella skillnader i personlighetsmåtten visade sig inte påverka effektiviteten av SET, vilket är ett nytt resultat som föreslår att SET kan fungera likvärdigt oavsett individuella skillnader i dessa mått. I den andra aspekten av studien undersöktes individuella skillnader i dessa personlighetsmått i responser på icke-aversiv osäkerhet. Osäkerhet manipulerades inom beslutsfattning i samma visuella diskrimineringsuppgift. Icke-aversiv osäkerhet tros vara relaterat till ångest, men detta har inte studerats extensivt. Individuella skillnader i Neuroticism och intolerance of uncertainty visade sig korrelera med uppskattad stress, men inte elektrodermal aktivitet, i delen av testet där osäkerheten ökades. Detta indikerar en relation mellan dessa ångestrelaterade personlighetsmått och negativa responser till icke-aversiv osäkerhet. Implikationer av resultat diskuteras. 

Abstract [en]

The aim of the current study was twofold. Firstly, to validate previous findings that stress exposure training (SET) improves performance and reduces stress levels during stressful tasks. The anxiety-related personality measures of Neuroticism and intolerance of uncertainty were also be employed to investigate whether these measures show any individual differences in the efficacy of SET. The test was a visual discrimination task paired with auditory stressors. Performance, rated stress, and electrodermal activity were measured. Mean scores were compared before and after SET, showing improved performance, decreased rated stress, and no changes in electrodermal activity. Individual differences in the personality measures were found to not mediate the efficacy of SET, suggesting a novel finding that SET is effective regardless of individual differences in these measures. The second aspect of this study related to individual differences in these personality measures in responses to non-aversive uncertainty. Uncertainty was manipulated in decision-making in the same visual discrimination task. Non-aversive uncertainty is thought to be linked to anxious responding, but this has not been extensively studied. Individual differences in Neuroticism and intolerance of uncertainty were found to correlate with self-reported stress, but not electrodermal activity, during a condition of increased non-aversive uncertainty. This indicates a relationship between these anxiety-related traits and negative responses to non-aversive uncertainty. Implications of findings are discussed.
