Acute And Chronic Stress

BACKGROUND Dealing with stress is of central importance. Lately, smartphone applications (apps) are deployed in stress interventions as they offer maximal flexibility for users. First results of experimental studies show that anti-stress apps effect subjective perception of stress positively (Ly et al., 2014). However, current literature lacks studies on physiological stress reactions (e.g., cortisol), although they are of special interest to health issues. OBJECTIVE Therefore, the aim of this study was to investigate the effectiveness of an anti-stress app in chronic and acute stress reduction on a physiological (cortisol) and psychological level (subjective perception of stress) in comparison to a face-to-face and a control group in a pre-post design, for the first time. METHODS Sixty-two participants took part in the pretesting procedure (drop-out of 53 %). Based on age, gender, physical activity and subjectively perceived acute stress due to the Trier Social Stress Test for groups (TSST-G; von Dawans et al., 2011) as well as based on subjectively chronic stress assessed during the pretest, participants were parallelized in three groups (anti-stress-app: n = 10, face-to-face: n = 11, control group: n = 9). RESULTS After six weeks of the cognitive-based resource-oriented intervention, participants were exposed to the TSST-G for post testing. Results did not show a change of cortisol secretion or cognitive appraisal of the acute stressor. Further, no changes were detected in the chronic physiological stress reaction. CONCLUSIONS Possible causes are discussed extensively. CLINICALTRIAL no
