For the diary data, the within-person reliability was calculated according to Cranford et al. [63]. According to George and Mallery [65], the values are interpreted as excellent if > .9, as good if > .8, as acceptable if > .7, as questionable if > .6, aspoor if > .5, and as unacceptable if < .5

^aIntraclass correlation coefficient; values below .50 indicate that variance is predominantly due to within-person-fluctuation
