With this caveat in mind , the results of the current meta- analysis suggest that hatha yoga does not have effects on acute , chronic and /or treatment-resistant mood and anxiety disorders compared to treatment as usual or active control groups .
However , when compared to psychoeducation , hatha yoga showed more reductions in depression .
BACKGROUND The aim of this study was to systematic ally investigate the effectiveness of hatha yoga in treating acute , chronic and /or treatment-resistant mood and anxiety disorders .
Monitoring Depression Treatment Outcomes With the Patient Health Questionnaire-9
Background : Although effective treatment of depressed patients requires regular follow-up contacts and symptom monitoring , an efficient method for assessing treatment outcome is lacking . We investigated responsiveness to treatment , reproducibility , and minimal clinical ly important difference of the  Patient Health Question naire-9 ( PHQ-9 )  , a st and ard instrument for diagnosing depression in primary care . Methods : This study included 434 intervention subjects from the IMPACT study , a multisite treatment trial of late-life depression ( 63 % female , mean age 71 years ) . Changes in  PHQ-9 scores over the course of time were evaluated with respect to change scores of the SCL-20 depression scale as well as 2 independent structured diagnostic interviews for depression during a 6-month period . Test-retest reliability and minimal clinical ly important difference were assessed in 2 subgroups of patients who completed the PHQ-9 twice exactly 7 days apart . Results : The PHQ-9 responsiveness as measured by effect size was significantly greater than the SCL-20 at 3 months ( −1.3 versus −0.9 ) and equivalent at 6 months ( −1.3 versus −1.2 ) . With respect to structured diagnostic interviews , both the PHQ-9 and the SCL-20 change scores accurately discriminated patients with persistent major depression , partial remission , and full remission . Test-retest reliability of the PHQ-9  was excellent , and its minimal clinical ly important difference for individual change , estimated as 2 st and ard errors of measurement , was 5 points on the 0 to 27 point PHQ-9 scale . Conclusions : Well-vali date d as a diagnostic measure , the PHQ-9 has now proven to be a responsive and reliable measure of depression treatment outcomes . Its responsiveness to treatment coupled with its brevity makes the PHQ-9 an attractive tool for gauging response to treatment in individual patient care as well as in clinical research
