Abstract
Introduction Acceptance and commitment therapy (ACT) has been shown to help treat depression. However, little is known about the patient's experiences with ACT. This study aimed to learn how it was used in adolescents with major depressive disorder who have achieved good treatment outcomes. Methods Five adolescents with major depressive disorder with good treatment outcomes of ACT were enrolled in the semi-structured qualitative interview and analyzed using systematic textual condensation and interpretative phenomenological analysis. Results Four primary themes emerged from the investigation. "Therapist relationships and characteristics" describes the therapist's receptiveness and respect for adolescents with depression and having a trustworthy and sincere therapist. "Spaces to explore and experience" describes the ongoing process and content of acceptance of negative emotions and mindfulness practices in the healing process. "Do important things" refers to values and committed action. The "time settings" include the frequency and duration of treatment. Conclusion Adolescents make positive changes with a receptive and respectful therapist by exploring themselves in a genuine and trusting therapeutic relationship. Improvement seems to come from being open to all thoughts and feelings and developing the ability to live in the present moment. Teenagers attach great importance to value-oriented behaviour. Therefore, treatment should target the critical areas of depressed adolescents to guide them towards recovery effectively.

Abstract
BACKGROUND Depression is one of the prevalent mental illnesses and leading cause of global disease burden. However, most people with depression do not access treatment. Remission without treatment may occur in some cases of depression. This study aimed to estimate the short-term remission (natural recovery) from untreated depression. METHODS A systematic review and meta-analysis was registered on PROSPERO and conducted following PRISMA guidelines. EMBASE, PsycINFO, and PubMed were searched, supplemented with an additional hand search to identify studies reporting natural recovery from untreated depression. Study selection and screening were carried out by three independent reviewers. Methodological quality assessment of the included studies was conducted. Remission was defined as no longer meeting the diagnostic criteria or scoring below the cut off points of the validated tools as reported by the included studies. The data were synthesized using narrative summary and random-effects meta-analysis. RESULTS Sixteen waitlist-controlled trial studies were included in the systematic review and meta-analysis. The duration of follow-up ranged from 4 to 12 weeks with a median duration of 8 weeks. The overall pooled remission from untreated depression was 12.5%, 95% confidence interval (7.8, 18.0%). Due to lack of published data, we were unable to determine if the severity of depression symptoms was associated with remission rates. CONCLUSIONS Short-term remission from depression without treatment is uncommon. Across studies, 8 - 18% of people remitted without treatment within 12 weeks. Waitlist control groups may not represent all persons with depression.

Abstract
Depressed individuals exhibit an attentional bias towards mood-congruent stimuli, yet evidence for biased processing of threat-related information in human interaction remains scarce. Here, we tested whether an attentional bias towards interpersonally aggressive pictures over interpersonally neutral pictures could be observed to a greater extent in depressed participants than in control participants. Eye movements were recorded while the participants freely viewed visually matched interpersonally aggressive and neutral pictures, which were presented in pairs. Across the groups, participants spent more time looking at neutral pictures than at aggressive pictures, probably reflecting avoidance behavior. When the participants could anticipate the stimulus valence, depressed participants - but not controls - showed an early attentional bias towards interpersonally aggressive pictures, as indexed by their longer first fixation durations on aggressive pictures than on neutral pictures. Our results thus preliminarily suggest both an early attentional bias towards interpersonal aggression, which is present, in depressed participants, also when aggression contents are anticipated, and a later attentional avoidance of aggression. The early depression-related bias in information processing may have maladaptive effects on the way depressed individuals perceive and function in social interaction and can, therefore, maintain depressed mood.

Abstract
Teacher stress and burnout contribute to attrition and stress-related health concerns. Despite some positive effects, previous mindfulness-based interventions (MBI) have failed to incorporate key elements of methodological rigor and have included large dosages despite research suggesting that such dosages are iatrogenic. The current study demonstrates the efficacy of a brief MBI (bMBI; four sessions, six total hours) to reduce self-reported stress, burnout, and depression, and suggests the bMBI can protect against deleterious impacts to physiological functioning. The study informs the design and implementation of future MBIs, including strategies for reducing intervention dosages, in order to improve effectiveness and maximize cost-effectiveness.

Abstract
OBJECTIVE In the past two decades, newer psychotherapy treatments have emerged for the treatment of major depression. This review aimed to comprehensively synthesize the evidence for mindfulness-based cognitive therapy (MBCT), acceptance and commitment therapy (ACT), and positive psychotherapy (PPT) in treating a current episode of major depression. METHODS A systematic search of the Ovid MEDLINE, Embase, PsycINFO, and Cochrane databases was conducted for randomized controlled trials of MBCT, ACT, and PPT for major depression. Standardized mean differences were calculated with Hedges' g to complete random-effects meta-analysis. Heterogeneity was assessed with the Cochran Q statistic and I2 statistic. Subgroup analysis was conducted to further investigate heterogeneity. RESULTS A random-effects meta-analysis of 15 studies (MBCT, N=7; ACT, N=4; PPT, N=4) revealed that all three therapies showed efficacy in reducing symptoms of depression with a small favorable effect, compared with all control conditions (N=946; Hedges' g=0.34; 95% confidence interval=0.14, 0.54; p<0.001). Cochrane's Q statistic (Q=32, df=15, p=0.007) suggested significant heterogeneity (I2=53%). A mixed-effects model test for subgroup differences showed significant differences between active controls and treatment-as-usual controls (χ2=15.3, df=1, p<0.001). Overall quality of evidence and publication bias were low. CONCLUSIONS Meta-analysis shows that MBCT and ACT may be superior to inactive or treatment-as-usual controls and that PPT may be comparable to active controls for reducing symptoms of major depression after an acute course of therapy. However, the quality of the evidence was low. High-quality studies are needed to confirm the efficacy of these interventions.

Abstract
Relapse rates following a depressive episode are high, with limited treatments available aimed at reducing such risk. Acceptance and commitment therapy (ACT) is a cognitive-behavioral approach that has gained increased empirical support in treatment of depression, and thus represents an alternative in relapse prevention. Psychological flexibility (PF) plays an important role in mental health according to the model on which ACT is based. This study aimed to investigate the role of PF and its subprocesses in reducing residual symptoms of depression and in improving positive mental health following an 8-week group-based ACT treatment. Adult participants (75.7% female) with a history of depression, but currently exhibiting residual symptoms (N = 106) completed measures before and after intervention, and at 6 and 12-month follow-up. A growth curve model showed that positive mental health increased over 12-months. Multilevel mediation modeling revealed that PF significantly mediated these changes as well as the reduction of depressive symptoms, and that processes of acceptance, cognitive defusion, values and committed action, in turn, mediated increased PF.

Abstract
Negative bias in face processing has been demonstrated in depression, but there are no longitudinal investigations of negative bias in symptom reduction. We recorded event-related potentials (P1 and N170) to task-irrelevant facial expressions in depressed participants who were later provided with a psychological intervention and in never depressed control participants. Follow-up measurements were conducted for the depressed group two and 39 months later. Negative bias was found specifically in the depression group, and was demonstrated as enlarged P1 amplitude to sad faces, which normalized in the follow-up measurements when the participants had fewer symptoms. Because the P1 amplitude recorded at the baseline did not differ between the depression group that recovered and the group that did not recover after the intervention, this brain response did not show potential as a biomarker for treatment response. It could have potential, however, to serve as a state-marker of depression.

Abstract
Depression is a highly recurrent disorder with limited treatment alternatives for reducing risk of subsequent episodes. Acceptance and commitment therapy (ACT) and attention bias modification (ABM) separately have shown some promise in reducing depressive symptoms. This study investigates (a) if group-based ACT had a greater impact in reducing residual symptoms of depression over a 12-month follow-up than a control condition, and (b) if preceding ACT with ABM produced added benefits. This multisite study consisted of two phases. In phase 1, participants with a history of depression, currently in remission (N = 244), were randomized to either receive 14 days of ABM or a control condition. In phase 2, a quasi- experimental design was adopted, and only phase-1 participants from the Sørlandet site (N = 124) next received an 8-week group-based ACT intervention. Self-reported and clinician-rated depression symptoms were assessed at baseline, immediately after phase 1 and at 1, 2, 6, and 12 months after the conclusion of phase 1. At 12-month follow-up, participants who received ACT exhibited fewer self-reported and clinician-rated depressive symptoms. There were no significant differences between ACT groups preceded by ABM or a control condition. There were no significant differences between ACT groups preceded by ABM or a control condition. Group-based ACT successfully decreased residual symptoms in depression over 12 months, suggesting some promise in preventing relapse.
