In the first paragraph of the right column on page 150, it is mentioned that the effect sizes of the PALME program in relation to the general psychological symptom load (GSI) would be −0.52 immediate after intervention and −0.28 at follow-up measurement. These descriptions are wrong. The real effect sizes are −0.77 at post measurement (t2) and −0.40 at follow-up-measurement (t3), as reported correctly in the result section on page 144.
