Abstract
Introductions: Anxiety & affective disorders are frequent comorbidities in patients with COPD as well as negative prognostic predictors. This is why rehabilitation guidelines postulate systematic assessments to screen for major depression (MD) & anxiety symptoms (AS). Scientific sources highlight positive effects in reduction of symptoms for 6 weeks & longer lasting rehabilitations.Objectives: The aims of this research are to find out how many of COPD patients show a MD or AS, whether a PR of 3 weeks can reduce symptoms & how sustainable these effects are.Methods: From Feb13–Aug14 555 COPD patients were screened by PHQ9 & GAD7 in terms of MD&AS at admission=T0 & dismissal=T1, as well as after 3=T2, 6=T3, 9=T4 & 12=T5 months after rehabilitation. Differences were analysed using cross tables&McNemar testing.Results: At T0 32% of all patients showed criteria of a MD (PHQ9³10) & 26,4% met the criteria of AS (GAD7³10). 20,1% revealed symptoms for MD&AS. The score reductions of PHQ9 in comparison from T0 to T1, T2, T3, T4 and reductions of GAD7 in comparison from T0 to T1, T3, T4, T5 were sig. For patients with symptoms of MD&AS score reductions were only sig. in comparison from T0 to T1.



Conclusion: This research shows that even after 3 weeks PR relevant reductions of anxiety & depression symptoms can be determined. Furthermore, some sustained effects were reviled.
