Name Time Method Possible effects of the experimental conditions were repeatedly assessed for up to 46 days after base-line (baseline=Tag 1, post-Expressive Writing=Tag 4, midterm follow up=Tag 10 und longterm-follow-up=Tag46) with the Positive and Negative Affect Schedule (PANAS, Krohne, Egloff, Kohlmann, & Tausch, 1996), which was a priori defined as outcome. The PANAS contains two scales with overall 10 five-point items assessing positive (e.g. interested, proud) and negative affect (e.g. upset, ashamed).
