Effect of cognitive behavioural therapy and yoga for generalised anxiety disorder on sleep quality in a randomised controlled trial: the role of worry, mindfulness, and perceived stress as mediators.

Sleep disturbances are present in ~65% of individuals with generalised anxiety disorder (GAD). Although both Kundalini yoga (KY) and cognitive behavioural therapy (CBT) are effective treatment options for GAD, little is known about how these treatments compare in improving sleep for GAD and what drives these changes. Accordingly, we examined the effects of CBT, KY, and stress education (SEdu; an attention control condition) on subjective sleep quality (as measured by the Pittsburgh Sleep Quality Index [PSQI] and Insomnia Severity Index [ISI]) in a randomised controlled trial of 226 adults with GAD (mean age 33.37 years; 70% female; 79% White). We hypothesised that both CBT and KY would outperform SEdu in improving sleep disturbances. Three potential mediators of sleep improvement (worry, mindfulness, perceived stress) were also examined. In line with hypotheses, PSQI and ISI scores significantly improved from pre- to post-treatment for all three treatment groups (all p < 0.001, all d > 0.97). However, contrary to predictions, sleep changes were not significantly greater for CBT or KY compared to SEdu. In mediation analyses, within-person deviations in worry, mindfulness, and stress each significantly mediated the effect of time on sleep outcomes. Degree of change in sleep attributable to worry (CBT > KY > SEdu) and perceived stress (CBT, KY > SEdu) was moderated by treatment group. Personalised medicine as well as combined treatment approaches should be studied to help reduce sleep difficulties for patients with GAD who do not respond.

Kripalu Yoga for Military Veterans With PTSD: A Randomized Trial.

OBJECTIVES: This randomized controlled trial of yoga for military veterans and active duty personnel with posttraumatic stress disorder (PTSD) evaluated the efficacy of a 10-week yoga intervention on PTSD. METHOD: Fifty-one participants were randomized into yoga or no-treatment assessment-only control groups. Primary outcome measures included questionnaires and the Clinician Administered PTSD Scale. RESULTS: Both yoga (n = 9) and control (n = 6) participants showed significant decreases in reexperiencing symptoms, with no significant between-group differences. Secondary within-group analyses of a self-selected wait-list yoga group (n = 7) showed significant reductions in PTSD symptoms after yoga participation, in contrast to their control group participation. Consistent with current literature regarding high rates of PTSD treatment dropout for veterans, this study faced challenges retaining participants across conditions. CONCLUSION: These results are consistent with recent literature indicating that yoga may have potential as a PTSD therapy in a veteran or military population. However, additional larger sample size trials are necessary to confirm this conclusion.

Evaluation of Yoga for Preventing Adolescent Substance Use Risk Factors in a Middle School Setting: A Preliminary Group-Randomized Controlled Trial.

Adolescence is a key developmental period for preventing substance use initiation, however prevention programs solely providing educational information about the dangers of substance use rarely change adolescent substance use behaviors. Recent research suggests that mind-body practices such as yoga may have beneficial effects on several substance use risk factors, and that these practices may serve as promising interventions for preventing adolescent substance use. The primary aim of the present study was to test the efficacy of yoga for reducing substance use risk factors during early adolescence. Seventh-grade students in a public school were randomly assigned by classroom to receive either a 32-session yoga intervention (n = 117) in place of their regular physical education classes or to continue with physical-education-as-usual (n = 94). Participants (63.2 % female; 53.6 % White) completed pre- and post-intervention questionnaires assessing emotional self-regulation, perceived stress, mood impairment, impulsivity, substance use willingness, and actual substance use. Participants also completed questionnaires at 6-months and 1-year post-intervention. Results revealed that participants in the control condition were significantly more willing to try smoking cigarettes immediately post-intervention than participants in the yoga condition. Immediate pre- to post-intervention differences did not emerge for the remaining outcomes. However, long-term follow-up analyses revealed a pattern of delayed effects in which females in the yoga condition, and males in the control condition, demonstrated improvements in emotional self-control. The findings suggest that school-based yoga may have beneficial effects with regard to preventing males' and females' willingness to smoke cigarettes, as well as improving emotional self-control in females. However additional research is required, particularly with regard to the potential long-term effects of mind-body interventions in school settings. The present study contributes to the literature on adolescence by examining school-based yoga as a novel prevention program for substance use risk factors.

Yoga Enhances Positive Psychological States in Young Adult Musicians.

Although yoga has been shown to be a viable technique for improving the performance of the mind and body, little attention has been directed to studying the relationship between yoga and the psychological states of flow and mindfulness. Musicians enrolled in a 2-month fellowship program in 2005, 2006 and 2007 were invited to participate in a yoga and meditation program. Fellows not participating in the yoga program were recruited separately as controls. All participants completed baseline and end-program questionnaires evaluating dispositional flow, mindfulness, confusion, and music performance anxiety. Compared to controls, yoga participants reported significant decreases in confusion and increases in dispositional flow. Yoga participants in the 2006 sample also reported significant increases in the mindfulness subscale of awareness. Correlational analyses revealed that increases in participants' dispositional flow and mindfulness were associated with decreases in confusion and music performance anxiety. This study demonstrates the commonalities between positive psychology and yoga, both of which are focused on enhancing human performance and promoting beneficial psychological states. The results suggest that yoga and meditation may enhance the states of flow and mindful awareness, and reduce confusion.

Yoga-enhanced cognitive behavioural therapy (Y-CBT) for anxiety management: a pilot study.

Cognitive behavioural therapy (CBT) is an effective treatment for generalized anxiety disorder, but there is still room for improvement. The aim of the present study was to examine the potential benefit of enriching CBT with kundalini yoga (Y-CBT). Participants consisted of treatment resistant clients at a community mental health clinic. A total of 32 participants enrolled in the study and 22 completed the programme. After the Y-CBT intervention, pre-post comparisons showed statistically significant improvements in state and trait anxiety, depression, panic, sleep and quality of life. Results from this preliminary study suggest that Y-CBT may have potential as a promising treatment for those suffering from generalized anxiety disorder. KEY PRACTITIONER MESSAGES: Yoga-enhanced cognitive behavioural therapy (Y-CBT) may be a promising new treatment for those suffering from generalized anxiety disorder. Y-CBT may also reduce depression in those suffering from generalized anxiety. Y-CBT may reduce depression and anxiety in a clinic population where clients suffer from multiple diagnoses including generalized anxiety disorder.

A Combined Kundalini Yoga and Cognitive Behavioral Therapy Program for Posttraumatic Stress Disorder: A Pilot Study.

Cognitive behavioral therapy (CBT) is one of the standard conventional treatments for posttraumatic stress disorder (PTSD). However, recent studies have reported the benefits of yoga for reducing PTSD symptoms including a Kundalini Yoga (KY) intervention. The purpose of this study was to test the efficacy of a novel combined 8-week CBT and KY program for treating PTSD symptoms and improving sleep quality in a single group trial of 26 adults with PTSD. PTSD symptoms (PTSD checklist-5) and sleep quality (Pittsburgh Sleep Quality Index) were assessed at baseline, post intervention, and at 2-month follow-up. Both CBT and yoga homework compliance were also measured. Total PTSD symptom scores as well as the cluster symptoms (intrusion, avoidance, arousal/reactivity, and negative alterations in cognitions and mood) were significantly improved following the program, all p < .01. The improvements in total PTSD scores, intrusion, avoidance, arousal/reactivity were maintained at follow-up, with all values still less (p < .01) than baseline. The negative alterations in cognitions and mood symptom cluster continued to improve further at follow-up compared to post-intervention values (p < .05). Total sleep score (p < .05) and the subscales of sleep disturbance (p < .01), daytime dysfunction (p < .05), and sleep quality (p < .01) were significantly improved after the program and these improvements were maintained at follow-up compared to baseline. Sleep medication use was decreased (p < .05) and sleep latency was improved (p < .01) at follow-up only compared to baseline. There was a significant positive correlation (p < .05) between the completion of the yoga home practice and post change in total sleep scores. These results show that a combined KY and CBT intervention resulted in decreased PTSD symptoms and improved sleep quality and suggest this program may constitute an additional treatment option for PTSD.

Changes in mindfulness facets across yoga, CBT and stress education in individuals with generalized anxiety disorder.

Improving mindfulness is an important treatment target for generalized anxiety disorder (GAD). However, less is known about how different treatments impact specific aspects of mindfulness. In a clinical trial (Simon et al., 2021), 226 individuals with GAD were randomized to 12 weeks of Kundalini Yoga (KY), cognitive behavioral therapy (CBT) or stress education (SE). To examine whether specific facets of mindfulness, as measured by the Five Facet Mindfulness Questionnaire (FFMQ) change more than others across treatment and between treatments, we ran a multi-variate multilevel growth curve model (MMLM). Results indicated that while the Non-judge, Act with Awareness, and Non-react facets increased significantly during treatment, the Observe and Describe facets did not. Improvement in the Acting with Awareness facet during treatment was significantly greater for KY than CBT. These findings reveal the need to better understand how behavioral treatments can influence specific components of mindfulness for those with anxiety.

Human phase response curve to a single 6.5 h pulse of short-wavelength light.

The photic resetting response of the human circadian pacemaker depends on the timing of exposure, and the direction and magnitude of the resulting shift is described by a phase response curve (PRC). Previous PRCs in humans have utilized high-intensity polychromatic white light. Given that the circadian photoreception system is maximally sensitive to short-wavelength visible light, the aim of the current study was to construct a PRC to blue (480 nm) light and compare it to a 10,000 lux white light PRC constructed previously using a similar protocol. Eighteen young healthy participants (18-30 years) were studied for 9-10 days in a time-free environment. The protocol included three baseline days followed by a constant routine (CR) to assess initial circadian phase. Following this CR, participants were exposed to a 6.5 h 480 nm light exposure (11.8 µW cm(-2), 11.2 lux) following mydriasis via a modified Ganzfeld dome. A second CR was conducted following the light exposure to re-assess circadian phase. Phase shifts were calculated from the difference in dim light melatonin onset (DLMO) between CRs. Exposure to 6.5 h of 480 nm light resets the circadian pacemaker according to a conventional type 1 PRC with fitted maximum delays and advances of -2.6 h and 1.3 h, respectively. The 480 nm PRC induced ∼75% of the response of the 10,000 lux white light PRC. These results may contribute to a re-evaluation of dosing guidelines for clinical light therapy and the use of light as a fatigue countermeasure.

Yoga reduces performance anxiety in adolescent musicians.

CONTEXT: Professional musicians often experience high levels of stress, music performance anxiety (MPA), and performance-related musculoskeletal disorders (PRMDs). Given the fact that most professional musicians begin their musical training before the age of 12, it is important to identify interventions that will address these issues from an early age. OBJECTIVE: This study intended to replicate and expand upon adult research in this area by evaluating the effects of a yoga intervention on MPA and PRMDs in a population of adolescent musicians. The present study was the first to examine these effects. DESIGN: The research team assigned participants, adolescent musicians, into two groups. The intervention group (n = 84) took part in a 6-wk yoga program, and the control group (n = 51) received no treatment. The team evaluated the effects of the yoga intervention by comparing the scores of the intervention group to those of the control group on a number of questionnaires related to MPA and PRMDs. SETTING: The study was conducted at the Boston University Tanglewood Institute (BUTI). BUTI is a training academy for advanced adolescent musicians, located in Lenox, Massachusetts. PARTICIPANTS: Participants were adolescent, residential music students (mean age = 16 y) in a 6-wk summer program at the BUTI in 2007 and 2008. INTERVENTION: Participants in the yoga intervention group were requested to attend three, 60-min, Kripalustyle yoga classes each wk for 6 wk. OUTCOME MEASURES: MPA was measured using the Performance Anxiety Questionnaire (PAQ) and the Music Performance Anxiety Inventory for Adolescents (MPAI-A). PRMDs were measured using the Performance-Related Musculoskeletal Disorders Questionnaire (PRMD-Q). RESULTS • Yoga participants showed statistically significant reductions in MPA from baseline to the end of the program compared to the control group, as measured by several subscales of the PAQ and MPAI-A; however, the results for PRMDs were inconsistent. CONCLUSION: The findings suggest that yoga may be a promising way for adolescents to reduce MPA and perhaps even prevent it in the future. These findings also suggest a novel treatment modality that potentially might alleviate MPA and prevent the early disruption and termination of musical careers.

Comparing Kundalini Yoga, cognitive behavioral therapy, and stress education for generalized anxiety disorder: Anxiety and depression symptom outcomes.

Increasingly, individuals with anxiety disorders are seeking mind-body interventions (e.g., yoga), but their effectiveness is unclear. This report summarizes seven additional, secondary outcomes measuring anxiety and depression symptoms from a study of 226 adults with generalized anxiety disorder who were randomized to 12-week Kundalini Yoga, Cognitive-Behavior Therapy (CBT) or stress education (control). At post-treatment, participants receiving CBT displayed significantly lower symptom severity, compared to those in the control group, on 6 of the 7 measures. Participants who received Yoga (vs. those in the control group) displayed lower symptom severity on 3 of the 7 measures. No significant differences were detected between participants receiving CBT vs those receiving Yoga. At the 6-month follow-up, participants from the CBT continued to display lower symptoms than the control group.

Human phase response curve to a 1 h pulse of bright white light.

The phase resetting response of the human circadian pacemaker to light depends on the timing of exposure and is described by a phase response curve (PRC). The current study aimed to construct a PRC for a 1 h exposure to bright white light (∼8000 lux) and to compare this PRC to a <3 lux dim background light PRC. These data were also compared to a previously completed 6.7 h bright white light PRC and a <15 lux dim background light PRC constructed under similar conditions. Participants were randomized for exposure to 1 h of either bright white light (n=18) or <3 lux dim background light (n=18) scheduled at 1 of 18 circadian phases. Participants completed constant routine (CR) procedures in dim light (<3 lux) before and after the light exposure to assess circadian phase. Phase shifts were calculated as the difference in timing of dim light melatonin onset (DLMO) during pre- and post-stimulus CRs. Exposure to 1 h of bright white light induced a Type 1 PRC with a fitted peak-to-trough amplitude of 2.20 h. No discernible PRC was observed in the <3 lux dim background light PRC. The fitted peak-to-trough amplitude of the 1 h bright light PRC was ∼40% of that for the 6.7 h PRC despite representing only 15% of the light exposure duration, consistent with previous studies showing a non-linear duration­response function for the effects of light on circadian resetting.

Development of Specific Aspects of Spirituality during a 6-Month Intensive Yoga Practice.

The majority of research on yoga focuses on its psychophysiological and therapeutic benefits, while the spiritual aspects are rarely addressed. Changes of specific aspects of spirituality were thus investigated among 160 individuals (91% women, mean age 40.9 ± 8.3 years; 57% Christians) starting a 2-year yoga teacher training. We used standardized questionnaires to measure aspects of spirituality (ASP), mindfulness (FMI-Freiburg Mindfulness Inventory), life satisfaction (BMLSS-Brief Multidimensional Life Satisfaction Scale), and positive mood (lightheartedness/relief). At the start of the course, scores of the respective ASP subscales for search for insight/wisdom, transcendence conviction, and conscious interactions/compassion were high, while those for religious orientation were low. Within the 6 month observation period, both conscious interactions/compassion (effect size, Cohen's d = .33), Religious orientation (d = .21), Lightheartedness/Relief (d = .75) and mindfulness (d = .53) increased significantly. Particularly non-religious/non-spiritual individuals showed moderate effects for an increase of conscious interactions/compassion. The results from this study suggest that an intensive yoga practice (1) may significantly increase specific aspects of practitioners' spirituality, mindfulness, and mood, (2) that these changes are dependent in part on their original spiritual/religious self-perception, and (3) that there are strong correlations amongst these constructs (i.e., conscious interactions/compassion, and mindfulness).

Effects of yoga on mental and physical health: a short summary of reviews.

This report summarizes the current evidence on the effects of yoga interventions on various components of mental and physical health, by focussing on the evidence described in review articles. Collectively, these reviews suggest a number of areas where yoga may well be beneficial, but more research is required for virtually all of them to firmly establish such benefits. The heterogeneity among interventions and conditions studied has hampered the use of meta-analysis as an appropriate tool for summarizing the current literature. Nevertheless, there are some meta-analyses which indicate beneficial effects of yoga interventions, and there are several randomized clinical trials (RCT's) of relatively high quality indicating beneficial effects of yoga for pain-associated disability and mental health. Yoga may well be effective as a supportive adjunct to mitigate some medical conditions, but not yet a proven stand-alone, curative treatment. Larger-scale and more rigorous research with higher methodological quality and adequate control interventions is highly encouraged because yoga may have potential to be implemented as a beneficial supportive/adjunct treatment that is relatively cost-effective, may be practiced at least in part as a self-care behavioral treatment, provides a life-long behavioural skill, enhances self-efficacy and self-confidence and is often associated with additional positive side effects.

A yoga intervention for music performance anxiety in conservatory students.

Music performance anxiety can adversely affect musicians. There is a need for additional treatment strategies, especially those that might be more acceptable to musicians than existing therapies. This pilot study examined the effectiveness of a 9-week yoga practice on reducing music performance anxiety in undergraduate and graduate music conservatory students, including both vocalists and instrumentalists. The intervention consisted of fourteen 60-minute yoga classes approximately twice a week and a brief daily home practice. Of the 24 students enrolled in the study, 17 attended the post-intervention assessment. Participants who completed the measures at both pre- and post-intervention assessments showed large decreases in music performance anxiety as well as in trait anxiety. Improvements were sustained at 7- to 14-month follow-up. Participants generally provided positive comments about the program and its benefits. This study suggests that yoga is a promising intervention for music performance anxiety in conservatory students and therefore warrants further research.

The Yoga Instructor Beliefs Scales Epistemic (YIBS-E) and Pedagogic (YIBS-P): Development and Initial Assessment of the Factor Structure.

Yoga is a multidimensional and heterogeneous mind-body practice led by a therapist or teacher (e.g., yoga instructor). Although they constitute an integral part of delivery, content, and curriculum, factors that influence yoga instructors' choices have yet to be explored. Using a mixed methods sequential design for development of an instrument that identifies measurable epistemic (YIBS-E) and pedagogic (YIBS-P) beliefs, the Yoga Instructor Beliefs Scale (YIBS) reports validity evidence from four distinct phases. Phase I presents qualitative findings from literature-informed semistructured interviews to give a comprehensive construct model of yoga instructor beliefs from diverse styles/ schools/lineages of yoga (nine content-specific clusters). In Phase II, focus group panels of experts evaluated construct novelty and importance of themes, resulting in a pool of potential questionnaire items. Phase III employed cognitive interviews to assess the perceived meaning and clarity of using the preliminary YIBS items. Phase IV included exploratory factor analysis and correlational analyses using 204 yoga instructor responses, suggesting a 44-item instrument with distinct epistemic (Experiential, Energetic, Systems-Based, Affectual, Mindful, and Physical) and pedagogic (Curricular Integration, Student Awareness, Accessibility, and Differentiated Instruction) factors (YIBS- E α = 0.90, YIBS-P α = 0.85). Measurable belief constructs can inform research on individual yoga instructor differences that may influence curriculum content choices and delivery. The purpose of this instrument is to enable research linking instructor beliefs to the presence of various components of a yoga program and to contextualize defining qualities of yoga programs. Long-term use of this instrument should enable in-depth analyses such as mediation or moderation of yoga instructor beliefs on intervention components/content or outcomes.

"Making it okay": professionals in high-stress environments construct their understanding of the impact of a yoga-based retreat designed to build resilience.

PURPOSE: While there is growing evidence for resilience building programmes, to date research has not explored how professionals construct understanding of programme impact. RISE (resilience, integration, self-awareness, engagement), a 5-day yoga-based retreat programme, has been linked with positive wellness outcomes. This qualitative inquiry explores participants' reflection and experience 3 months after programme completion. METHODS: Through a grounded constructivist lens, in-depth semi-structured phone interviews were conducted with 17 adult professionals in high-stress work environments who attended RISE. Initial hand-coding informed codebook development for systematic coding using directed content analysis using sensitizing structuring. RESULTS: Two integrated perceptions woven through five themes. Persistent threads of experiential learning and sense of permission provided structure for themes found. Five interrelated themes related to psychological health and workplace dynamics were (1) use of acquired behavioural skills and practices; (2) lived mindfulness; (3) resilience to stress and emotion regulation (4) self-care and self-compassion, and (5) sharing with others. CONCLUSION: Findings provide meaningful interpretation of previously reported programme efficacy by contextualizing perceived benefits within participants' constructed understanding of change. Specifically, environmental, social, and experiential considerations have suggested implications for resilience building programmes.Abbreviations: RISE (resilience, integration, self-awareness, engagement).

A systematic review of in vivo stretching regimens on inflammation and its relevance to translational yoga research.

OBJECTIVE: To conduct a systematic review evaluating the impact of stretching on inflammation and its resolution using in vivo rodent models. Findings are evaluated for their potential to inform the design of clinical yoga studies to assess the impact of yogic stretching on inflammation and health. METHODS: Studies were identified using four databases. Eligible publications included English original peer-reviewed articles between 1900-May 2020. Studies included those investigating the effect of different stretching techniques administered to a whole rodent model and evaluating at least one inflammatory outcome. Studies stretching the musculoskeletal and integumentary systems were considered. Two reviewers removed duplicates, screened abstracts, conducted full-text reviews, and assessed methodological quality. RESULTS: Of 766 studies identified, 25 were included for synthesis. Seven (28%) studies had a high risk of bias in 3 out of 10 criteria. Experimental stretching protocols resulted in a continuum of inflammatory responses with therapeutic and injurious effects, which varied with a combination of three stretching parameters--duration, frequency, and intensity. Relative to injurious stretching, therapeutic stretching featured longer-term stretching protocols. Evidence of pro- and mixed-inflammatory effects of stretching was found in 16 muscle studies. Evidence of pro-, anti-, and mixed-inflammatory effects was found in nine longer-term stretching studies of the integumentary system. CONCLUSION: Despite the overall high quality of these summarized studies, evaluation of stretching protocols paralleling yogic stretching is limited. Both injurious and therapeutic stretching induce aspects of inflammatory responses that varied among the different stretching protocols. Inflammatory markers, such as cytokines, are potential outcomes to consider in clinical yoga studies. Future translational research evaluating therapeutic benefits should consider in vitro studies, active vs. passive stretching, shorter-term vs. longer-term interventions, systemic vs. local effects of stretching, animal models resembling human anatomy, control and estimation of non-specific stresses, development of in vivo self-stretching paradigms targeting myofascial tissues, and in vivo models accounting for gross musculoskeletal posture.

Impact of preference for yoga or cognitive behavioral therapy in patients with generalized anxiety disorder on treatment outcomes and engagement.

There is some, but inconsistent, evidence to suggest that matching patient treatment preference enhances treatment engagement and outcome. The current study examined differential preferences and factors associated with treatment preference for 12-week group cognitive behavioral therapy (CBT), yoga, or stress education in 226 adults with generalized anxiety disorder (GAD; 70% female, Mean age = 33 ± 13.5). In a subsample of 165 patients who reported an intervention preference and were randomized to yoga or CBT, we further examined whether match to preferred intervention improved the primary treatment outcome (responder status on Clinical Global Impressions Scale) and engagement (dropout, homework compliance). Preferences for CBT (44%) and yoga (40%) were similar among patients. Women tended to prefer yoga (OR = 2.75, p = .01) and CBT preference was associated with higher baseline perceived stress (OR = 0.92, p = .04) and self-consciousness meta-cognitions (OR = 0.90, p = .02). Among those not matched to their preference, treatment response was higher for those receiving CBT than yoga (OR = 11.73, p = .013); there were no group differences for those matched to their treatment preference. In yoga, those who received their preference were more likely to drop than those who did not (OR = 3.02, 95% CI = [1.20, 7.58], p = .037). This was not the case for CBT (OR = 0.37, 95% CI = [0.13, 1.03], p = .076). Preference match did not predict homework compliance. Overall, results suggest that treatment preference may be important to consider to optimize outcome and engagement; however, it may vary by treatment modality. Future research incorporating preference, especially with yoga for anxiety, is aligned with personalized medicine.

Treatment of chronic primary sleep onset insomnia with Kundalini yoga: a randomized controlled trial with active sleep hygiene comparison.

STUDY OBJECTIVES: Prior studies have suggested a benefit of yoga for alleviating sleep disturbance; however, many studies have had methodological limitations. This trial study aimed to extend that literature by including an active sleep hygiene comparison. METHODS: Participants aged 25-59 years with a primary complaint of sleep onset insomnia lasting at least 6 months were block randomized to an 8-week Kundalini yoga or sleep hygiene intervention, both consisting of initial 60-minute instruction and weekly check-ins. Daily sleep diaries and questionnaires were collected at baseline, throughout the intervention, and at 6-month follow-up. Data were analyzed using linear mixed models (n = 20 in each group). RESULTS: Participant ratings of the interventions did not significantly differ. Sleep hygiene improved several diary and questionnaire outcomes, however, yoga resulted in even greater improvements corresponding to medium-to-large between-group effect sizes. Total sleep time increased progressively across yoga treatment (d = 0.95, P = .002), concurrent with increased sleep efficiency (d = 1.36, P < .001) and decreased sleep onset latency (d = -1.16, P < .001), but without changes in pre-sleep arousal (d =-0.30, P = .59). Remission rates were also higher for yoga compared to sleep hygiene, with ≥ 80% of yoga participants reporting average sleep onset latency < 30 minutes and sleep efficiency > 80% at 6-month follow-up. For over 50% of yoga participants, the insomnia severity index decreased by at least 8 points at end of treatment and follow-up. CONCLUSIONS: Yoga, taught in a self-care framework with minimal instructor burden, was associated with self-reported improvements above and beyond an active sleep hygiene comparison, sustained at 6-month follow-up. Follow-up studies are needed to assess actigraphy and polysomnography outcomes, as well as possible mechanisms of change.

A 3-Day residential yoga-based program improves education professionals' psychological and occupational health in a single arm trial.

OBJECTIVE: This study examined changes in psychological and occupational health in urban education professionals after attending a brief yoga-based program. METHODS: Education professionals from the New York City Department of Education (NYC DOE) who were attending a residential 3-day yoga-based program at Kripalu Center for Yoga & Health were recruited to participate in the study. Measures of psychological and occupational health and health-related behaviors were completed before (baseline), after (post), and two months after the program (follow-up). Paired samples t-tests were used to compare scores between time points. RESULTS: At post, participants (N = 74) showed improvements in stress, resilience, affect, mindfulness, empowerment, self-compassion, satisfaction with life, work engagement, burnout, exercise, and vegetable intake (all p values < 0.05) compared to baseline. At the follow-up (N = 33), showed improvements in resilience, affect, mindfulness, empowerment, self-compassion, work engagement, and burnout (all p values < 0.05) compared to baseline. There were significant correlations between the degree of home practice of the skills and techniques learned in the program and improvements in multiple measures of psychological and occupational health at follow-up (all p values < 0.05). CONCLUSIONS: These findings suggest that the yoga-based program improves psychological and occupational health and healthy behaviors in education professionals immediately following the program and up to two-months following the program, however, more data with larger sample sizes are needed to confirm sustained benefits over the longer term.
