BACKGROUND: Prior data suggests the Mindfulness-Based Interventions: (MBI) Teaching Assessment Criteria (MBI:TAC) has good inter-rater reliability, but many raters knew teacher experience level. OBJECTIVE: We sought to further evaluate the MBI-TACs inter-rater reliability and obtain preliminary data on predictive validity. METHODS: We videorecorded 21 MBSR teachers from academic and community settings. We trained 19 experienced MBI teachers in using the MBI:TAC. MBSR teachers were rated by three assessors; teachers and their assessors did not know one another. To assess predictive validity, MBSR students in courses taught by 18 of the MBSR teachers were invited to complete PROMIS-29 measures before the MBSR course, at the end of the course (month 2), and month 4. RESULTS: Intraclass correlation coefficients (ICCs) representing a single rater ranged from 0.33 to 0.56 on the 6 MBI:TAC domains. Using an average of two raters, ICC estimates ranged from 0.48 to 0.71 and ICCs generalizing to an average of three raters ranged from 0.6 to 0.8. Among n = 152 participating MBSR students, we found improvements from baseline to 2 months and 4 months in PROMIS measures of Anxiety, Depression, Fatigue, Sleep, and Social Role function (range in improvement 2.3 to 6.3, P < 0.0001 for all comparisons except Social Role at 2 months, P = 0.007). Higher MBI:TAC ratings were associated with greater improvements in anxiety among MBSR students from baseline to 2 months, with a -0.31 lower participant anxiety score per 1 unit increase in MBI:TAC composite teaching rating (95% CI -0.58, -0.05, P = 0.019), but we did not find statistically significant relationships with improvements in other PROMIS-29 domains. CONCLUSIONS: ICCs indicated good reliability using an average of three ratings, but inter-rater reliability was only fair using a single rater. We found initial validation that higher MBI:TAC ratings predicted greater improvements in anxiety symptoms in MBSR participants.

BackgroundThe Mindfulness-Based Interventions: Teaching Assessment Criteria (MBI:TAC) is an important tool for assessing teacher skill and aspects of the fidelity of mindfulness-based interventions, but prior research on and implementation of the MBI:TAC has used video recordings, which can be difficult to obtain, share for assessments, and which increase privacy concerns for participants. Audio-only recordings might be a useful alternative, but their reliability is unknown.ObjectiveTo assess evaluator perception of the rating process and inter-rater reliability of MBI:TAC ratings using audio-only recordings.MethodsWe prepared audio-only files from video recordings of 21 previously rated Mindfulness-Based Stress Reduction teachers. Each audio recording was rated by 3 trained MBI:TAC assessors drawn from a pool of 12 who had previously participated in rating the video recordings. Teachers were rated by evaluators who had not viewed the video recording and did not know the teacher. We then conducted semi-structured interviews with evaluators.ResultsOn the 6 MBI:TAC domains, the intraclass correlation coefficients (ICCs) for audio recordings ranged from .53 to .69 using an average across 3 evaluators. Using a single rating resulted in lower ICCs (.27-.38). Bland-Altman plots showed audio ratings had little consistent bias compared to video recordings and agreed more closely for teachers with higher ratings. Qualitative analysis identified 3 themes: video recordings were particularly helpful when rating less skillful teachers, video recordings tended to provide a more complete picture for rating, and audio rating had some positive features.ConclusionsInter-rater reliability of the MBI:TAC using audio-only recordings was adequate for many research and clinical purposes, and reliability is improved when using an average across several evaluators. Ratings using audio-only recordings may be more challenging when rating less experienced teachers.

BackgroundMindfulness-based cognitive therapy (MBCT) is an effective group intervention for reducing rates of depression relapse. However, about one-third of graduates experience relapse within 1 year of completing the course.ObjectiveThe current study aimed to explore the need and strategies for additional support following the MBCT course.MethodsWe conducted 4 focus groups via videoconferencing, two with MBCT graduates (n = 9 in each group) and two with MBCT teachers (n = 9; n = 7). We explored participants' perceived need for and interest in MBCT programming beyond the core program and ways to optimize the long-term benefits of MBCT. We conducted thematic content analysis to identify patterns in transcribed focus group sessions. Through an iterative process, multiple researchers developed a codebook, independently coded the transcripts, and derived themes.ResultsParticipants said the MBCT course is highly valued and was, for some, "life changing." Participants also described challenges with maintaining MBCT practices and sustaining benefits after the course despite using a range of approaches (ie, community and alumni-based meditation groups, mobile applications, taking the MBCT course a second time) to maintain mindfulness and meditative practice. One participant described finishing the MBCT course as feeling like "falling off a cliff." Both MBCT graduates and teachers were enthusiastic about the prospect of additional support following MBCT in the form of a maintenance program.ConclusionSome MBCT graduates experienced difficulty maintaining practice of the skills they learned in the course. This is not surprising given that maintained behavior change is challenging and difficulty sustaining mindfulness practice after a mindfulness-based intervention is not specific to MBCT. Participants shared that additional support following the MBCT program is desired. Therefore, creating an MBCT maintenance program may help MBCT graduates maintain practice and sustain benefits longer-term, thereby decreasing risk for depression relapse.

Mindfulness training programmes have shown to encourage prosocial behaviours and reduce antisocial tendencies in adolescents. However, less is known about whether training affects susceptibility to prosocial and antisocial influence. The current study investigated the effect of mindfulness training (compared with an active control) on self-reported prosocial and antisocial tendencies and susceptibility to prosocial and antisocial influence. 465 adolescents aged 11-16 years were randomly allocated to one of two training programmes. Pre- and post-training, participants completed a social influence task. Self-reported likelihood of engaging in prosocial and antisocial behaviours did not change post-training, and regardless of training group, participants showed a higher propensity for prosocial influence than for antisocial influence. Finally, participants were less influenced by antisocial ratings following both training programmes.

There is evidence that universal school-based mindfulness training (SBMT) can have positive effects for young people. However, it is unknown who benefits most from such training, how training exerts effects, and how implementation impacts effects. This study aimed to provide an overview of the evidence on the mediators, moderators, and implementation factors of SBMT, and propose a conceptual model that can be used both to summarize the evidence and provide a framework for future research. A scoping review was performed, and six databases and grey literature were searched. Inclusion and exclusion criteria were applied to select relevant material. Quantitative and qualitative information was extracted from eligible articles and reported in accordance with PRISMA-ScR guidelines. The search produced 5479 articles, of which 31 were eligible and included in the review. Eleven studies assessed moderators of SBMT on pupil outcomes, with mixed findings for all variables tested. Five studies examined the mediating effect of specific variables on pupil outcomes, with evidence that increases in mindfulness skills and decreases in cognitive reactivity and self-criticism post-intervention are related to better pupil outcomes at follow-up. Twenty-five studies assessed implementation factors. We discuss key methodological shortcomings of included studies and integrate our findings with existing implementation frameworks to propose a conceptual model. Widespread interest in universal SBMT has led to increased research over recent years, exploring who SBMT works for and how it might work, but the current evidence is limited. We make recommendations for future research and provide a conceptual model to guide theory-led developments. [This article was co-authored by the MYRIAD Team.]

BackgroundThe Mindfulness-Based Interventions: Teaching Assessment Criteria (MBI:TAC) is a widely used tool for assessing fidelity in mindfulness-based program (MBP) research and training. It also supports MBP teacher reflective and skill development. MBI:TAC assessors review MBP teaching and rate the teaching on 6 domains. The MBI:TAC yields individual domain and overall scores, using 6 levels of competence. Although the MBI:TAC is widely used in MBP research and training, research is at an early stage.ObjectiveWe developed and tested a method of training MBI:TAC assessors to use the tool reliably and examined interrater reliability of the tool.MethodsA total of 31 international senior MBP teachers were recruited to join an online training to build their skills in using the MBI:TAC. The training systematically and iteratively built familiarity and skills in assessing the 6 MBI:TAC domains. Qualitative and quantitative data on trainee's experience of the training were gathered. Interrater reliability in using the tool was tested each week of the training. At the end of the training, interrater reliability was tested by asking trainees to individually assess videos that they had not previously seen. Their ratings were compared to benchmark assessments, which had been established via consensus agreement between 4 expert users of the MBI:TAC.ResultsThe training was well received and appreciated, with some challenges experienced in applying the assessment methodology. Participants' ratings became progressively more in line with one another and the benchmark ratings during the training. At the end, interrater reliability was high (ranging from 0.67 to 1.0).ConclusionIt is possible for senior MBP trainers, coming from different regions in the world, to align toward common understandings of the elements of MBP teaching competence and program integrity. An assessor training methodology was tested, and the learning from this project has led to refinements for future delivery.

Mindfulness training (MT) is considered appropriate for school teachers and enhances well-being. Most research has investigated the efficacy of instructor-led MT. However, little is known about the benefits of using self-taught formats, nor what the key mechanisms of change are that contribute to enhanced teacher well-being. This study compared instructor-led and self-taught MT based on a book (Williams & Penman, 2011) in a sample of secondary school teachers. We assessed expectancy, the degree to which participants believed the intervention was effective, their program engagement, well-being and psychological distress, and evaluated whether mindfulness and self-compassion skills acted as mediators of outcomes. In total, 206 teachers from 43 schools were randomized by school to an instructor-led or self-taught course--77% female, mean age 39 years (SD = 9.0). Both MT formats showed similar rates of participant expectancy and engagement, but the instructor-led arm was perceived as more credible. Using linear mixed-effects models, we found the self-taught arm showed significant pre-post improvements in self-compassion and well-being, while the instructor-led arm showed such improvements in mindfulness, self-compassion, well-being, perceived stress, anxiety, depression, and burnout. Changes over time significantly differed between the groups in all these outcomes, favoring the instructor-led arm. The instructor-led arm, compared with the self-taught, indirectly improved teacher outcomes by enhancing mindfulness and self-compassion as mediating factors. Mindfulness practice frequency had indirect effects on teacher outcomes through mindfulness in both self-taught and instructor-led arms. Our results suggest both formats are considered reasonable, but the instructor-led is more effective than the self-taught. Trial registration: ISRCTN18013311.

Objective: To explore mediated effects of Mindfulness-Based Cognitive Therapy-"Taking it Further" (MBCT-TiF) on mental well-being through changes in mindfulness, self-compassion, and decentering. Method: A secondary analysis of an RCT using simple mediation, with 164 graduates of MBCT and mindfulness-based stress reduction (MBSR), was implemented whereby MBCT-TiF (vs ongoing mindfulness practice; OMP) was the independent variable; changes in mindfulness, self-compassion, and decentering during the intervention were the mediators; and mental well-being at post-intervention, whilst controlling for baseline, was the dependent variable. Secondary outcomes included psychological quality of life, depression, and anxiety. Results: Compared to OMP, MBCT-TiF experienced significant improvements in mental well-being through changes in all three mediators (mindfulness: ab = 0.11 [0.03, 0.25]; decentering: ab = 0.16 [0.05, 0.33]; self-compassion: ab = 0.07 [0.01, 0.18]). A similar pattern was demonstrated for depression, but only mindfulness and decentering mediated effects on psychological quality of life and anxiety. Conclusion: The findings provide preliminary support for all three mediators in driving change in mental well-being in a sample of MBCT/MBSR graduates. Future work must be theory-driven and powered to test all mediators in parallel and alongside other potential mediators (e.g., equanimity) to further understand independent contributions and interacting effects.

Objective: Mindfulness-based cognitive therapy (MBCT) is a viable alternative to maintenance antidepressant medication (M-ADM) to reduce risk of relapse/recurrence (RR) in recurrent depression, but its mechanism of action is not yet fully articulated. This secondary analysis of the PREVENT trial examined if MBCT with support to taper medication (MBCT-TS) reduces risk of RR in part by enhancing positive affect (PA). Method: In a single-blind, parallel, group randomized controlled trial, adults with ≥3 prior depressive episodes, but not currently in episode and who were taking M-ADM, were randomized to receive either MBCT-TS or ongoing maintenance M-ADM. The primary outcome was RR over 24-month follow-up. Levels of positive affect were assessed at intake and posttreatment. The original PREVENT trial was preregistered (ISRCTN 26666654), but this secondary analysis was not. Results: Four hundred and twenty-four individuals (predominantly female and of White British ethnicity) were recruited, with 212 randomized to each arm. MBCT-TS led to significantly greater PA relative to M-ADM at posttreatment assessment (Δ = 2.78, 95% CI [1.47, 4.08], p <.001). RR was experienced during follow-up by 194 individuals (100 M-ADM; 94 MBCT-TS). Greater intake PA predicted a reduced hazard of RR across treatments (p <.001; hazard ratio =.96, 95% CI [0.94, 0.98]). In individuals who had not relapsed by posttreatment with complete data (121 M-ADM; 145 MBCT-TS), greater increase in PA from intake to posttreatment mediated reduced risk of subsequent RR (p =.04). Conclusions: These findings suggest that greater levels of PA predict reduced risk of RR and that MBCT-TS in part acts to protect from RR when withdrawing from M-ADM by increasing PA. What is the public health significance of this article?: Depression has a chronic relapsing–remitting course for many individuals, and to optimize interventions to minimize the risk of relapse recurrence, it is important to further understand how current preventative treatments work. The current findings show that reduced levels of positive affect (PA) predict an increased risk of relapse/recurrence and that mindfulness-based cognitive therapy with support to taper from antidepressant medication (MBCT-TS) in part acts to reduce risk of relapse/recurrence by increasing levels of PA. This suggests that the protective effects of MBCT-TS could be further enhanced by more systematically targeting PA. [ABSTRACT FROM AUTHOR]

Adolescence is marked by the onset of puberty, which is associated with an increase in mental health difficulties, particularly in girls. Social and self‐referential processes also develop during this period: adolescents become more aware of others' perspectives, and judgements about themselves become less favourable. In the current study, data from 119 girls (from London, UK) aged 9–16 years were collected at two‐time points (between 2019 and 2021) to investigate the relationship between puberty and difficulties in mental health and emotion regulation, as well as the role of self‐referential and social processing in this relationship. Structural equation modelling showed that advanced pubertal status predicted greater mental health and emotion regulation difficulties, including depression and anxiety, rumination and overall difficulties in emotion regulation, and in mental health and behaviour. Advanced pubertal status also predicted greater perspective‐taking abilities and negative self‐schemas. Exploratory analyses showed that negative self‐schemas mediated the relationships between puberty and rumination, overall emotion regulation difficulties, and depression (although these effects were small and would not survive correction for multiple comparisons). The results suggest that advanced pubertal status is associated with higher mental health and emotion regulation problems during adolescence and that negative self‐schemas may play a role in this association. Research Highlights: This study investigates the relationship between puberty, mental health, emotion regulation difficulties, and social and self‐referential processing in girls aged 9–16 years.Advanced pubertal status was associated with worse mental health and greater emotion regulation difficulties, better perspective‐taking abilities and negative self‐schemas.Negative self‐schemas may play a role in the relationships between advanced pubertal status and depression, and advanced pubertal status and emotion regulation difficulties, including rumination.

We addressed construct validity and explored the relationship between self-compassion and compassion for others using the two main current operationalizations of compassion (Neff's and the Sussex-Oxford Compassion Scales, SOCSs). Relationships with psychological distress and wellbeing, and potential differences in the association between self-compassion and compassion for others by level of psychological distress and wellbeing were also explored. Participants (n = 811) completed the Spanish adaptations of the Self-Compassion Scale (SCS), the Compassion Scale (CS), the SOCSs (for the self/others), the Short Warwick–Edinburgh Mental Well-Being Scale (SWEMWBS), and the Depression Anxiety Stress Scales-21 (DASS-21). We fitted bifactor models to estimate the general factor of each construct for the different operationalizations, and calculated correlations between them. Relationships between self-compassion and compassion for others from the same operationalization were intermediate, while those between the same constructs from different operationalizations were large. Both constructs showed positive associations with wellbeing, while only self-compassion was associated with decreased psychological distress. Participants with good mental health showed higher associations between self-compassion and compassion for others than those with poorer mental health. Self-compassion and compassion for others appear to be dimensional constructs that can converge or diverge. When they converge, it is associated with better mental health. [ABSTRACT FROM AUTHOR]
