简要总结
Although antidepressants are the primary treatment for major depression, response and remission rates are unsatisfactory. The primary objective of this study is to identify if adding interpersonal group therapy (IPT-G) to the usual psychopharmacological and clinical management treatment will improve depressive symptoms in major depression outpatients.
详细描述
Patients presenting a current unipolar depression episode (BDI-II > 18) without response to 2 adequate antidepressants trials (optimized by dose and time) will be randomly allocated to two arms: a) Treatment-as-usual (TAU) arm: antidepressant + Clinical management; b) Add-on strategy arm: 14 sessions of IPT-Group added to TAU.
IPT-Group will be delivered following manualized guidelines (WHO, 2016 and Stuart et al. 2012). The choice of antidepressants for TAU will be based on the Canadian Network for Mood and Anxiety Treatments (CANMAT) recommendations. Clinical management will follow the National Institute for Mental Health (NIMH) recommendations for clinical management.
Depression episode will be diagnosed using the Mini International Neuropsychiatric Interview (MINI-PLUS).
The following variables will be evaluated at baseline and the end of the add-on intervention in both arms of the study:
a) depression symptoms- Beck Depression Inventory (BDI-II; b) anxiety symptoms - Beck Anxiety Inventory (BAI); c) quality of life- World Health Organization Quality of life Instrument short version (WHOQOL-bref); d) social support- Medical Outcomes Study Social. Support Survey (MOS-SSS); e) resilience- The Brief Resilience Scale (BRS); f) attachment- The Adult Attachment Scale (AAS-R) Depression symptoms are the primary outcome. Anxiety symptoms and quality of life the secondary outcomes. Social support, resilience, and attachment will be considered as both secondary outcome and mediator or moderators in a multivariate model.
