RESUMO
BACKGROUND: In this study, we re-examined data from a previous randomized controlled trial investigating 'technology supported mindfulness' (TSM)-an 8-week treatment intervention for individuals experiencing OCD. The current analysis involves an examination of the longitudinal relationships between rumination, worry and OCD symptom changes during mindfulness treatment, in comparison to a waitlist control. METHODS: Participants experiencing OCD (n = 71) were randomly assigned to 8 weeks of (1) TSM or (2) waitlist control. We tested the extent to which rumination (using the Ruminative Response Scale) and worry (using the Penn State Worry Questionnaire) are associated with OCD symptom changes during the acute phase of treatment, concurrently (i.e., within the same longitudinal model). RESULTS: Generalized linear model (GLM) results indicated a significant time (week 1 vs. week 8) by condition interaction involving decreased rumination in the TSM condition: F(1, 61) = 13.37, p = 0.001, partial η2 = 0.18 and observed power = 0.94. A second GLM demonstrated decreased worry in the TSM condition: F(1, 69) = 37.34, p = 0.001, partial η2 = 0.35 and observed power = 0.83. Longitudinal 'latent difference' structural equation analyses demonstrated a cross-lagged association between worry (but not rumination) and OCD symptom changes. CONCLUSIONS: Individuals in the TSM condition experienced greater reductions in rumination and worry during 8 weeks of TSM treatment compared to the waitlist control, and reduced worry predicted subsequent OCD symptom reduction.

Mindfulness-based interventions (MBIs) have emerged as clinically effective interventions for anxiety and depression although there are significant barriers to their access in the general population. The present study examined the effectiveness of a 5-week abbreviated mindfulness-based cognitive therapy (MBCT) intervention for a physician-referred, treatment-seeking, community sample (N = 54) with mood and/or anxiety symptom burden. Treatment effects demonstrated significant reductions in mood and anxiety symptom severity and significant increases in general well-being. Observed effect sizes were generally large, with high response and remission rates. The present study offers preliminary support that an abbreviated MBCT protocol can offer large treatment effects for decreasing mood and anxiety symptoms and could potentially offer an effective population-level strategy to improve cost-effectiveness and access to care.
RESUMO
BACKGROUND: Self-harm (SH) is among the strongest risk factors for eventual suicide death yet there are limited data on which interventions are most effective for treating SH in youth. METHODS: This single-blind, pilot randomized controlled trial examined brief cognitive behavioral therapy (BCBT) for suicide prevention vs. minimally-directive supportive psychotherapy in youth (aged 16-26) hospitalized following SH. Both therapies included 10 acute sessions over 15 weeks with three booster sessions occurring at three month intervals thereafter. The primary feasibility outcome was ≥70% retention at study endpoint. Efficacy measures, including repeat SH, were secondary outcomes. RESULTS: Twenty-four subjects were enrolled (12 per group) with one BCBT subject and two controls dropping out prior to the first therapy session. Five (45%) of the remaining BCBT subjects and seven (70%) control subjects completed all 10 acute therapy sessions. All subjects who completed five sessions went on to complete 10. There were significantly fewer instances of repeat SH in BCBT subjects (7 of 62 weeks of acute follow-up; 11%) compared to control subjects (24 of 79 weeks; 30%)(OR 0.34, 95%CI:0.13-0.92). Three subjects, all in the control condition, made a total of five suicide attempts during the study. LIMITATIONS: This study had a modest sample size and retention rate. CONCLUSIONS: This study failed to achieve its primary feasibility retention goal for BCBT. However, it did demonstrate that initial adherence to follow-up predicted study completion. Despite small numbers, it also found a significant reduction in repeat SH in the BCBT group, a finding which requires replication.

BACKGROUND AND OBJECTIVES: Up to 50% of patients undergoing hemodialysis suffer from symptoms of depression and/or anxiety. Access to traditional pharmacotherapies and psychotherapies for depression or anxiety in this patient population has been inadequate. The objective of this study was to investigate the feasibility and effectiveness of brief mindfulness meditation intervention for patients on hemodialysis with depression and anxiety symptoms. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This study was a randomized, controlled, assessor-blinded trial conducted in an urban hemodialysis unit. Forty-one patients were randomly assigned to intervention (n=21) and treatment-as-usual (n=20) groups. The intervention group received an 8-week individual chairside meditation intervention lasting 10-15 minutes, three times a week during hemodialysis. Feasibility outcomes were primarily assessed: enrollment rates, intervention completion rates, and intervention tolerability. Symptoms of depression and anxiety were measured using the Patient Health Questionnaire (PHQ-9) and the General Anxiety Disorder-7 (GAD-7). RESULTS: Of those deemed eligible for the study, 67% enrolled (41 of 61). Of the participants randomized to the intervention group, 71% completed the study, with meditation being well tolerated (median rating of 8 of 10 in a Likert scale; interquartile range=10-5 of 10). Barriers to intervention delivery included frequent hemodialysis shift changes, interruptions by staff or alarms, space constraints, fluctuating participant medical status, and participant fatigue. Meditation was associated with subjective benefits but no statistically significant effect on depression scores (change in PHQ-9, -3.0±3.9 in the intervention group versus -2.0±4.7 in controls; P=0.45) or anxiety scores (change in GAD-7, -0.9±4.6 versus -0.8±4.8; P=0.91). CONCLUSIONS: On the basis of the results of this study, mindfulness meditation appears to be feasible and well tolerated in patients on hemodialysis with anxiety and depression symptoms. The study did not reveal significant effects of the interventions on depression and anxiety scores.
