“…Mean amount of missing data across participants was 18.5% (range 2.8–45.9%). We performed all analyses with the data available bearing in mind the limitations of this approach (Peng and Chen, 2021 ). Only one participant failed to respond at posttest and follow-up and another one failed to respond at follow-up.…”

Traditionally, yoga is a multicomponent practice consisting of postures, breathing techniques, meditation, mantras, and ethics. To date, only a few studies have tried to dismantle the effects of each of these components and their combinations. To fill this gap, we examined the incremental effects of ethical education and physical Hatha yoga on mantra meditation using a single-case multiple-baseline design. This study was part of a project evaluating the new mind–body program Meditation-Based Lifestyle Modification. Fifty-seven healthy participants with no regular yoga or meditation practice were randomly assigned to three baselines (7, 14, and 21 days) and four conditions using a random number generator. The conditions were mantra meditation alone (MA), meditation plus physical yoga (MY), meditation plus ethical education (ME), and meditation plus yoga and ethical education (MYE). All the interventions lasted for 8 weeks and were run consecutively according to baseline length. During the baseline and treatment phases, participants received daily questionnaires measuring their well-being (WHO-5 Well-Being Index), stress (Perceived Stress Scale), and subjective experiences. Forty-two participants completed the treatment and were entered in the analyses. We analyzed our data using visual inspection, effect size estimation (Tau-U), and multilevel modeling. Almost all participants showed a longitudinal increase in well-being. Regarding between-group differences, participants who received ethical education exhibited the largest increases in well-being (Tau-U = 0.30/0.23 for ME/MYE), followed by participants in the MY condition (Tau-U = 0.12). Conversely, participants in the MA condition showed no change (Tau-U = 0.07). There was a tendency for the combined treatments to decrease stress. This tendency was strongest in the MY condition (Tau-U = –0.40) and reversed in the MA condition (Tau-U = 0.17). These results emphasize the incremental and differential effects of practicing meditation in combination with other practices from the eight-fold yoga path. This approach is valuable for better understanding the multifaceted practice of yoga.Clinical Trial Registration:www.ClinicalTrials.gov, identifier: NCT04252976.

Objective To prospectively document changes in adolescents’ sleep before versus during the COVID-19 pandemic, and to examine their impact on adolescents’ perceived stress. Methods Sixty-two typically developing adolescents participated in the study before (Time 1: January 15 to March 13, 2020) and during (Time 2: May 15 to June 30, 2020) the COVID-19 pandemic in Canada. At Time 1, each participant’s sleep pattern was assessed in the home environment using actigraphy and sleep logs for seven consecutive nights. Adolescents completed a battery of questionnaires in which they reported on their sleep schedule, duration, and quality, as well as their activities at bedtime, their daytime sleepiness, and their social/emotional behavior. The participants’ parents provided demographic information. At Time 2, each participant completed a sleep log, the same battery of questionnaires regarding sleep, and the Perceived Stress Scale. Results (1) Adolescents’ reported sleep was of longer duration and on a delayed schedule during the COVID-19 pandemic compared to pre-pandemic. (2) A larger proportion of adolescents reported meeting or exceeding the recommended amount of sleep during the COVID-19 pandemic compared to pre-pandemic sleep. (3) “Social jet lag” disappeared during the COVID-19 pandemic. (4) A shorter reported sleep duration and higher level of arousal at bedtime at Time 1 were significant predictors of adolescents’ perceived stress at Time 2—during the COVID-19 pandemic. (5) A higher levels of arousal at bedtime and lower reported sleep quality at Time 2 were concurrently associated with higher levels of perceived stress among adolescents, even when we controlled for the levels of pre-pandemic emotional or behavioral issues, sleep duration, or sleep quality. Conclusion Sleep duration and cognitive-emotional arousal, which are both modifiable behaviors, were associated with adolescents’ perceived stress during the COVID-19 pandemic. These behaviors could be useful targets for preventive interventions aiming to reduce adolescents’ stress in the face of stressogenic situations, such as the COVID-19 pandemic.

“…Noncompleters did not differ significantly from completers on child diagnosis or a number of demographic variables, though there was a difference by intervention condition. Peng and Chen (2021) depicted 20% attrition as a common benchmark for “studies related to youth, school‐based programs, and clinical trials” (p. 1), which would place the rate in this study within the normal range, even if not desired. At the item level, given that someone participated at all, about 8% of data were missing.…”

Parents matter: Parent acceptance of school‐based executive functions interventions relates to improved child outcomes

et al. 2022

Objectives School‐based interventions with parent‐training components might improve access among lower‐income families to effective help for children with neurodevelopmental disorders. This potential might be realized, however, only if parents perceive the interventions as acceptable and therefore engage with treatment. Methods Parents (N = 124) of 3rd−5th grade students diagnosed with Autism Spectrum Disorder or Attention‐Deficit/Hyperactivity Disorder rated the acceptability of their child's treatment (one of two culturally responsive behavioral interventions). Parent engagement was measured through attendance at parent training sessions and the extent to which they read a corresponding workbook. Results Education and income correlated inversely with parent perceptions of treatment acceptability. Acceptability correlated positively with engagement, more strongly among lower‐income families. Acceptability had an indirect effect on treatment outcome, mediated by parent engagement. Conclusions Treatment providers should focus on strategies to increase parent acceptability, with particular attention to improving access for lower‐income families.
