Mindfulness-based and Compassion-based Interventions in Anxious-Depressive Symptomatology in Mental Health Services

The aim of this study is to assess and compare the benefits of twopsychological interventions added to the usual treatment of patients whocome to mental health. Patients will be randomly assigned to the followingconditions: Mindfulness-Based Stress Reduction (MBSR), Attachment-BasedCompassion Therapy (ABCT) and a Treatment As Usual (TAU) Group. Theparticipants in the two psychological intervention groups will also receive usualpsychological/psychiatric treatment managed by their specialist. Mindfulnessand Compassion groups will be composed of 33 participants each, and TAU group will be composed of 64 participants (total sample n = 130). The principal hypothesis is that \'ABCT + TAU\' will be more effective than\'MBSR + TAU\' for treating depressive and/or anxiety symptoms in patients attending mental health settings. Secondary hypothesis are: 1) \'MBSR + TAU\'and \'ABCT + TAU\' will be more effective than \'TAU alone\' for treatinganxiety and/or depressive symptoms in patients attending mental health settings; 2) mindfulness will be a mediator of the \'MBSR + TAU\' program improvements, while self-compassion will be a mediator of the corresponding\'ABCT + TAU\'; and 3) \'ABCT + TAU\' will present more cost-effectiveness than \'MBSR + TAU\' and both ABCT + TAU\' and \'MBSR + TAU\' programs will present more cost-effectiveness than TAU alone.
