Design outcomes

Primary

Measure	Time frame
I. Interindividual fluctuations: There are considerable interindividual variations between PTSD participants regarding symptom fluctuations and applied coping strategies (EMA data). II. Intraindividual fluctuations: Next to interindividual variations, there also are substantial intraindividual variations, e.g., patterns of symptom increase and decrease, variety of applied coping strategies, and effectivity of those strategies (EMA data).	—

Secondary

Measure	Time frame
III. Associations with biomarkers: For participants with proximal traumatization, hair cortisol concentration (HCC) is expected to be positively correlated to symptom severity and negatively correlated to coping efficacy, and vice-versa for participants with more distal traumatization (EMA; questionnaires t0, t1, t2, t3; hair sampling t0 and t3). IV. Associations with psychological variables: Individual coping efficacy and variability are inversely associated with symptom severity and posttraumatic cognitions and positively associated with individual abilities of emotion regulation (EMA; hair sampling t0 and t3). V. Psychoendocrine Covariance: The associations of biomarkers with EMA self-report are closer than those of biomarkers with retrospective self-report (EMA; questionnaires t0, t1, t2, t3; hair sampling t0 and t3).	—
