RESUMEN

BACKGROUND: Traditional in-person psychotherapies are incapable of addressing global mental health needs. Use of computer-based interventions is one promising solution for closing the gap between the amount of global mental health treatment needed and received. OBJECTIVE: Although many meta-analyses have provided evidence supporting the efficacy of self-guided, computer-based interventions, most report low rates of treatment engagement (eg, high attrition and low adherence). The aim of this study is to investigate the efficacy of an adjunctive treatment component that uses task shifting, wherein mental health care is provided by nonspecialist peer counselors to enhance engagement in an internet-based, self-directed, evidence-based mindfulness intervention among Chinese university students. METHODS: From 3 universities across China, 54 students who reported at least mild stress, anxiety, or depression were randomly assigned to a 4-week internet-based mindfulness intervention (MIND) or to the intervention plus peer counselor support (MIND+), respectively. Be Mindful delivers all the elements of mindfulness-based cognitive therapy in an internet-based, 4-week course. Participants completed daily monitoring of mindfulness practice and mood, as well as baseline and posttreatment self-reported levels of depression, anxiety, stress, and trait mindfulness. We screened 56 volunteer peer counselor candidates who had no former training in the delivery of mental health services. Of these, 10 were invited to participate in a day-long training, and 4 were selected. Peer counselors were instructed to provide 6 brief (15-20 minute) sessions each week, to help encouraging participants to complete the internet-based intervention. Peer counselors received weekly web-based group supervision. RESULTS: For both conditions, participation in the internet-based intervention was associated with significant improvements in mindfulness and mental health outcomes. The pre-post effect sizes (Cohen d) for mindfulness, depression, anxiety, and stress were 0.55, 0.95, 0.89, and 1.13, respectively. Participants assigned to the MIND+ (vs MIND) condition demonstrated significantly less attrition and more adherence, as indicated by a greater likelihood of completing posttreatment assessments (16/27, 59% vs 7/27, 26%; χ21=6.1; P=.01) and a higher percentage of course completion (72.6/100, 72.6% vs 50.7/100, 50.7%; t52=2.10; P=.04), respectively. No significant between-group differences in daily frequency and duration of mindfulness practice were observed. Multilevel logistic growth models showed that MIND+ participants reported significantly greater pre-post improvements in daily stress ratings (interaction estimate 0.39, SE 0.18; t317=2.29; P=.02) and depression (interaction estimate 0.38, SE 0.16; t330=2.37; P=.02) than those in the MIND condition. CONCLUSIONS: This study provides new insights into effective ways of leveraging technology and task shifting to implement large-scale mental health initiatives that are financially feasible, easily transportable, and quickly scalable in low-resource settings. The findings suggest that volunteer peer counselors receiving low-cost, low-intensity training and supervision may significantly improve participants' indices of treatment engagement and mental health outcomes in an internet-based mindfulness intervention among Chinese university students.

RESUMEN

BACKGROUND: The neural mechanisms associated with anhedonia treatment response are poorly understood. Additionally, no study has investigated changes in resting-state functional connectivity (rsFC) accompanying psychosocial treatment for anhedonia. METHODS: We evaluated a novel psychotherapy, Behavioral Activation Therapy for Anhedonia (BATA, n = 38) relative to Mindfulness-Based Cognitive Therapy (MBCT, n = 35) in a medication-free, transdiagnostic, anhedonic sample in a parallel randomized controlled trial. Participants completed up to 15 sessions of therapy and up to four 7T MRI scans before, during, and after treatment (n = 185 scans). Growth curve models estimated change over time in anhedonia and in rsFC using average region-of-interest (ROI)-to-ROI connectivity within the default mode network (DMN), frontoparietal network (FPN), salience network, and reward network. Changes in rsFC from pre- to post-treatment were further evaluated using whole-network seed-to-voxel and ROI-to-ROI edgewise analyses. RESULTS: Growth curve models showed significant reductions in anhedonia symptoms and in average rsFC within the DMN and FPN over time, across BATA and MBCT. There were no differences in anhedonia reductions between treatments. Within-person, changes in average rsFC were unrelated to changes in anhedonia. Between-person, higher than average FPN rsFC was related to less anhedonia across timepoints. Seed-to-voxel and edgewise rsFC analyses corroborated reductions within the DMN and between the DMN and FPN over time, across the sample. CONCLUSIONS: Reductions in rsFC within the DMN, FPN, and between these networks co-occurred with anhedonia improvement across two psychosocial treatments for anhedonia. Future anhedonia clinical trials with a waitlist control group should disambiguate treatment versus time-related effects on rsFC.

RESUMEN

BACKGROUND: The menopause transition is associated with an increased risk of depressive symptoms. The current study aimed to test whether Mindfulness-Based Stress Reduction, an 8-week group intervention involving meditation and yoga, might reduce the risk of depressive symptoms among perimenopausal women. A secondary aim was to examine baseline characteristics, including sensitivity to estradiol fluctuation, as a moderator of treatment effects. METHODS: 104 healthy women from the community in the menopause transition were enrolled and randomized to MBSR (n = 52) or a waitlist control condition (n = 52). Randomization was carried out using a random number generator and opaque sealed envelopes. Depressive symptoms, the main outcome, were assessed every two weeks for 6 months using the Center for Epidemiologic Studies Depression Scale (CES-D). The occurrence of an elevated CES-D score (≥16) and of a major depressive episode were pre-identified secondary outcomes. The following surveys were used to assess additional outcomes of interest every two months: the Perceived Stress Scale, Spielberger Trait Anxiety Inventory, Connor-Davidson Resilience Scale, and Pittsburgh Sleep Quality Index. Baseline characteristics examined as potential moderators of treatment benefit included: baseline CES-D score, past depressive episodes, recent stressful life events, a history of physical or sexual abuse, and emotional sensitivity to reproductive hormone fluctuation. Outcome assessors were blinded to the participants' assigned treatment arm. RESULTS: Outcome data were available for 44 women assigned to MBSR and 51 women in the waitlist condition. Women randomized to MBSR reported fewer depressive symptoms, less perceived stress, less anxiety, increased resilience, and improved sleep (ps < 0.001). Furthermore, several baseline characteristics predicted a greater mood benefit of MBSR, including: a history of major depression (p for the interaction <0.001), a greater number of recent stressful life events (p < .001), being in the early menopause transition (p = .002), and an increased emotional sensitivity to reproductive hormone fluctuation (p = .004). There were no group differences in the occurrence of major depressive episodes (p > .05). CONCLUSIONS: MBSR appears to be an effective intervention for the prevention of depressive symptoms in the menopause transition.

RESUMEN

Borderline personality disorder (BPD) is a psychological disorder characterized by dysregulation across multiple domains. While selected mindfulness-based interventions are effective in addressing symptoms of BPD, less is known regarding the effects of engaging in brief mindfulness practices on affective correlates of BPD. The present study investigated the effects of engaging in brief, daily mindfulness practice in a sample of young adults with elevated BPD symptoms. Ninety-two participants were recruited and randomly assigned to 2 weeks of daily mindfulness meditation or relaxation practice (active control), or to a no-practice control condition. Participants completed measures assessing depression, anxiety, stress, shame, difficulties with emotion regulation, trait mindfulness, and self-compassion before and after the practice period. Compared to the no-practice control condition, mindfulness practice resulted in significant improvements in trait mindfulness and self-compassion, whereas relaxation practice led to reductions in emotion regulation difficulties. No significant differences were found on any of the other outcomes between the mindfulness and relaxation conditions. The findings suggest that while both mindfulness and relaxation-based practices are effective in targeting selected transdiagnostic processes associated with BPD, more intensive interventions may be required for the practices to induce changes at the level of psychological symptoms.

RESUMEN

As adolescence can be a stressful developmental stage, the purpose of this study was to determine if a novel mindful self-compassion program would decrease stress, depressive symptoms, and anxiety and increase resilience, gratitude, and curiosity/exploration (positive risk-taking), and to ascertain if mindfulness and self-compassion co-varied with these outcomes over time. Forty-seven adolescents in the southeast U.S. enrolled in an 8-week mindful self-compassion course in five cohorts. Measures were assessed at pre-intervention, post-intervention, and 6-week follow-up. Multilevel growth analyses revealed main effects of time on perceived stress, resilience, curiosity/exploration and gratitude. Additionally, both mindfulness and self-compassion co-varied with perceived stress and depressive symptoms; mindfulness also co-varied with anxiety and self-compassion co-varied with resilience and curiosity/exploration. Implications of these findings are that this program has potential in decreasing stress and increasing resilience and positive risk-taking. Future studies with a control group need to be conducted to confirm these findings.

RESUMEN

The present study investigated the relative effects of mindfulness, reappraisal and suppression in reducing sadness, and the extent to which implementation of these strategies affects cognitive resources in a laboratory context. A total of 171 Singaporean undergraduate participants were randomly assigned to receive brief training in mindfulness, reappraisal, or suppression prior to undergoing a sad mood induction. Individual adherence to Asian cultural values was assessed as a potential moderator of strategy effectiveness. Participants rated their mood and completed a Color-Word Stroop task before and after mood regulation instructions. Analyses using multi-level modelling showed that the suppression condition caused less robust declines in sadness over time compared to mindfulness. There was also a nonsignificant trend in which mindfulness was associated with greater sadness recovery compared to reappraisal. Suppression resulted in lower average sadness compared to mindfulness among those high on Asian cultural values, but not those low on Asian cultural values. Both mindfulness and reappraisal buffered against increases in Stroop interference from pre-to post-regulation compared to suppression. The findings highlight the advantage of mindfulness as a strategy effective not only in the regulation of sad mood, but also in the preservation of cognitive resources in the context of mood regulation.

RESUMEN

Trait mindfulness, or the capacity for nonjudgmental, present-centered attention, predicts lower aggression in cross-sectional samples, an effect mediated by reduced anger rumination. Experimental work also implicates state mindfulness (i.e., fluctuations around one's typical mindfulness) in aggression. Despite evidence that both trait and state mindfulness predict lower aggression, their relative impact and their mechanisms remain unclear. Higher trait mindfulness and state increases in mindfulness facets may reduce aggression-related outcomes by (1) limiting the intensity of anger, or (2) limiting rumination on anger experiences. The present study tests two hypotheses: First, that both trait and state mindfulness contribute unique variance to lower aggressiveness, and second, that the impact of both trait and state mindfulness on aggressiveness will be uniquely partially mediated by both anger intensity and anger rumination. 86 participants completed trait measures of mindfulness, anger intensity, and anger rumination, then completed diaries for 35 days assessing mindfulness, anger intensity, anger rumination, anger expression, and self-reported and behavioral aggressiveness. Using multilevel zero-inflated regression, we examined unique contributions of trait and state mindfulness facets to daily anger expression and aggressiveness. We also examined the mediating roles of anger intensity and anger rumination at both trait and state levels. Mindfulness facets predicted anger expression and aggressiveness indirectly through anger rumination after controlling for indirect pathways through anger intensity. Individuals with high or fluctuating aggression may benefit from mindfulness training to reduce both intensity of and rumination on anger.

RESUMEN

The pain of rejection is a crucial component of normal social functioning; however, heightened sensitivity to rejection can be impairing in numerous ways. Mindfulness-based interventions have been effective with several populations characterized by elevated sensitivity to rejection; however, the relationship between mindfulness and rejection sensitivity has been largely unstudied. The present study examines associations between rejection sensitivity and multiple dimensions of dispositional mindfulness, with the hypothesis that a nonjudgmental orientation to inner experiences would be both associated with decreased rejection sensitivity and attenuate the impact of sensitivity to rejection on general negative affect. A cross-sectional sample of undergraduates (n = 451) completed self-report measures of rejection sensitivity, dispositional mindfulness, and trait-level negative affect. Significant zero-order correlations and independent effects were observed between most facets of dispositional mindfulness and rejection sensitivity, with nonjudging demonstrating the largest effects. As predicted, rejection sensitivity was associated with negative affectivity for people low in nonjudging (ß = .27, t = 5.12, p < .001) but not for people high in nonjudging (ß = .06, t = .99, p = .324). These findings provide preliminary support for mindfulness, specifically the nonjudging dimension, as a protective factor against rejection sensitivity and its effects on affect.

RESUMEN

OBJECTIVES: Mindfulness training reduces anger and aggression, but the mechanisms of these effects are unclear. Mindfulness may reduce anger expression and hostility via reductions in anger rumination, a process of thinking repetitively about angry episodes that increases anger. Previous research supports this theory but used measures of general rumination and assessed only the present-centered awareness component of mindfulness. The present study investigated associations between various aspects of mindfulness, anger rumination, and components of aggression. METHOD: The present study used self-report measures of these constructs in a cross-sectional sample of 823 students. RESULTS: Structural equation modeling revealed that anger rumination accounts for a significant component of the relationship between mindfulness and aggression, with the largest effect sizes demonstrated for the nonjudgment of inner experiences facet of mindfulness. CONCLUSION: Nonjudgment and present-centered awareness may influence aggression via reduced anger rumination. The importance of examining mindfulness as a multidimensional construct is discussed.

RESUMEN

Training in mindfulness is a well-supported therapeutic strategy for pain conditions, though short-term mindfulness training for acute pain is not always effective. To explore the possibility that initial attempts at mindfulness in people without previous training may drain self-regulatory resources, the current study used a student sample (N=63) to test the hypothesis that brief instruction in mindfulness would lead to reduced pain tolerance on a cold pressor task (CPT), compared to more familiar strategies for coping with acute pain. We also investigated whether high heart rate variability (HRV), a physiological indicator of self-regulatory capacity, would predict pain tolerance. Higher HRV predicted greater pain tolerance only in the control group, suggesting that applying unfamiliar mindfulness strategies while attempting to tolerate pain more rapidly sapped self-regulatory strength.

RESUMEN

Although self-report measures of dispositional mindfulness have good psychometric properties, a few studies have shown unexpected positive correlations between substance use and mindfulness scales measuring observation of present-moment experience. The current study tested the hypothesis that the relationship between present-moment observation and substance use is moderated by the tendency to be nonjudgmental and nonreactive toward the observed stimuli. Two hundred and ninety-six undergraduates completed the five-facet mindfulness questionnaire (FFMQ), a calendar measuring periods of substance use, and a measure of the five-factor model of personality. Controlling for FFMQ and personality subscales, significant interactions between the observing and nonreactivity subscales indicated that the observing subscale was negatively associated with substance use at higher levels of nonreactivity but positively associated with periods of substance use at lower levels of nonreactivity. Results support the use of statistical interactions among FFMQ subscales to test for the presence of interactive effects of different aspects of mindfulness.
