The impact of exercise environments on adolescents’ cognitive and psychological outcomes: A randomised controlled trial

Exercise in natural environments can improve cognition, positive affect, and reduce psychological stress. However, it remains unclear whether these benefits are subject to a gradient effect, whereby more natural features confer greater cognitive and psychological benefits. This study examined the influence of the exercise environment (i.e., the degree of nature) on cognition, and psychological outcomes in a sample of adolescents (n = 90; mean age = 14.3 ±.05 years). Four groups were randomised to one of the following experimental conditions: a non-exercise indoor control, indoor exercise, park exercise, and exercise in a nature reserve. Participants’ self-reported their stress, affect, and vitality and completed two measures of cognition (‘Rapid Visual Information Processing’ and ‘Spatial Working Memory’) immediately before and ~6 min after exercise. All exercise conditions participated in a group-based circuit lasting ~20 min, which included a mixture of aerobic and body-weight resistance activities. Linear mixed models were used to examine changes within and between groups. The indoor group increased sustained attention accuracy compared to the park group. There were no between-group differences in working memory. The indoor and nature groups increased cognitive arousal compared to control. The park group improved in state-level vitality compared to control. The mixed-results of this research do not support our ‘nature gradient’ hypothesis, whereby cognitive and psychological outcomes would improve in accordance with the degree of nature present in the exercise environment.     

Emphasizing appearance versus health outcomes in exercise: The influence of the instructor and participants’ reasons for exercise

The objectifying nature of exercise environments may prevent women from reaping psychological benefits of exercise. The present experiment manipulated self-objectification through an exercise class taught by an instructor who emphasized exercise as either a means of acquiring appearance or health outcomes. The purpose of this study was to test for interactions between the class emphasis and participants’ reasons for exercise (i.e., appearance, health) predicting participants’ state self-objectification, state social physique anxiety, exercise class enjoyment, and future intentions of returning to a similar exercise class. Results, obtained via pre- and post-exercise questionnaires, revealed a significant interaction between class emphasis and health reasons for exercise predicting state self-objectification. Participants with lower health reasons for exercise reported greater state self-objectification in the appearance-focused class compared to those with higher health reasons for exercise. Adopting stronger health reasons for exercise may buffer exercise participants from the more objectifying aspects of the group exercise environment.     

Exceptional reported effects and data anomalies merit explanation from “A randomized controlled trial of coordination exercise on cognitive function in obese adolescents” by Liu et al. (2018)

We read the article in Psychology of Sport and Exercise by Liu et al. (“A randomized controlled trial of coordination exercise on cognitive function in obese adolescents”) with great interest. Our interest in the article stemmed from the extraordinary differences in obesity-related outcomes reported in response to a rope-jumping intervention. We requested the raw data from the authors to confirm the results and, after the journal editors reinforced our request, the authors graciously provided us with their data. We share our evaluation of the original data herein, which includes concerns that weight and BMI loss by the intervention appears extraordinary in both magnitude and aspects of the distributions. We request that the authors address our findings by providing explanations of the extraordinary data or correcting any errors that may have occurred in the original report, as appropriate.     

Rebellious teens? Genetic and environmental influences on the social attitudes of adolescents

Genetic and environmental influences in social attitudes were investigated in adopted and nonadopted children (N = 654) and their biological and adoptive relatives in the Colorado Adoption Project. Conservatism and religious attitudes were measured in the children annually from ages 12 to 15 and in the parents during the 12-year-old visit. Multivariate genetic model fitting indicated that both conservatism and religious attitudes are strongly influenced by shared-family environmental factors throughout adolescence. In contrast to previous findings from twin studies, which suggest that genetic influence on social attitudes does not emerge until adulthood, the present study detected significant genetic influence in conservatism as early as age 12. There was no evidence of genetic influence, however, on religious attitudes during adolescence.

The illusion of mental health: in the mind of which beholder?

We reference self-ratings and clinician ratings of childhood anxious symptoms to a third data source well delineated with regard to the pathophysiology of anxiety. A total of 36 children with anxiety disorders and other children were administered yohimbine, an alpha-sub-2-adrenoreceptor antagonist, in response to which anxiety-prone children have blunted output of growth hormone. We assessed neuroendocrine reactions. In general, participants who claimed anxiety that was unconfirmed by clinicians displayed anxiotypic neuroendocrine profiles, whereas those who denied anxiety detected by clinicians did not, suggesting self-report may have had the advantage over clinician ratings in some instances. Nuanced and contextualized conclusions in this area of work are needed. In response to the question "the illusion of mental health: in the mind of which beholder?," we answer "it depends on the sample and the syndrome under study."     

Crying wolf? Australian adolescents’ perceptions of the ambiguity of visible indicators of mental health and authenticity of mental illness

Young people’s perspectives about mental health concepts shape both their interactions with sufferers of mental illness and their actions related to their own mental health. The current study employed a cross-sectional qualitative design to explore how adolescents (aged 12–18 years) speak about mental health and illness in order to gain insight into young people’s perceptions and experiences and contribute to shaping approaches to policy and practice. When discussing mental health concepts and appropriate behaviours toward sufferers of mental illness, adolescents conveyed a sense of acceptance and understanding of the potential complexity and severity of mental health problems. In contrast, when discussing mental health in the context of their own lives, a stronger sense of scepticism was conveyed, with students expressing difficulty with the lack of visible markers of mental health and confusion determining authenticity in the mental health states conveyed by their peers. Interestingly, adolescents interviewed commonly conveyed the notion that young people may exaggerate or “fake” a mental illness for personal gain. Adolescent perceptions of mental health and illness hold practical implications for policy and school-based programs aimed at improving mental health knowledge, attitudes and behaviours among youth.     

Randomized trial testing the integration of the Good Behavior Game and MyTeachingPartner™: The moderating role of distress among new teachers on student outcomes

A growing body of research documents the effectiveness of classroom management programs on a range of student outcomes, yet few early-career teachers receive training on these practices prior to entering the classroom. Moreover, few studies have attended to how variations in teacher distress or level of classroom misbehavior affects training benefits. This study reports findings from a randomized trial of a teacher training program that combined two evidence-based programs (Good Behavior Game [GBG] and MyTeachingPartner™ [MTP]) to determine their impact on novice teachers and their students. In addition, the current study reports findings on moderated impacts by initial teacher distress as well as the overall classroom level of misbehavior. The sample included 188 early-career teachers (grades K-3) in their first three years of teaching from three large, urban school districts. Analyses indicated that intervention had no main effects, but yielded moderated impact depending on the combination of the baseline levels of classroom disruptive behavior and teacher distress; it appears that the program impacts were greatest in the highest risk circumstance (i.e., high teacher stress and elevated challenging student behaviors). For those classrooms, those assigned to intervention evidence improved behavior and student achievement compared to control counterparts by the spring of the training year, relative to the fall baseline (d = 0.18–0.70 depending on outcome). This study is significant in that it highlights effects during a critical window of training and coaching for early career teachers and the need to consider teacher and classroom contextual factors that may moderate professional development efforts.     

Effects of massage intervention on discharged premature infants’ weight,parental stress,and parent–child attachment: A randomized controlled trial

Infant massage enhances the growth and development of premature infants and promotes parent–child bonding. However, its effects on parental stress and parent–child attachment in premature infants, as well as gender differences thereof, remain unclear. In this randomized controlled trial, we used a repeated-measures design and included 61 premature infants (mean gestational age: 35.1 ± 1.5 weeks). Weight, parental stress, and parent–child attachment were measured at multiple time points: before massage and 1, 4, 8, and 12 weeks after commencing infant massage. The results revealed that the massage group infants had significantly higher weight gain than the control (no massage) group infants at all four time points. Moreover, parents in the massage group reported notably lower levels of stress than those in the control group, particularly in the parental distress and difficult children subscales. No significant between-group differences were observed in parent–child attachment. Furthermore, no significant differences were observed between fathers and mothers in parental stress and parent–child attachment. However, fathers reported higher levels of distress than mothers at 4 and 12 weeks. In conclusion, infant massage led to increased infant weight and reduced parental stress over time, and differences between fathers and mothers were not significant, except fathers exhibiting higher levels of distress than mothers over time. Healthcare professionals should educate and support parents on infant massage before discharge of premature infants.     

Sociocultural correlates of compulsive exercise: is the environment important in fostering a compulsivity towards exercise among adolescents?

Sociocultural factors hypothesised to be influential in eating disorders were assessed for their relationship with compulsive exercise. A sample of 828 adolescent boys and girls completed measures assessing sociocultural messages to change body shape as well as pressure to be thin, and also measures of compulsive exercise and disordered eating. Results showed that the sociocultural influences differed slightly between boys and girls. Hierarchical regressions showed that, after controlling for disordered eating and BMI, messages to become more muscular and media pressure to be thin significantly predicted compulsive exercise in boys, while the same regression in girls reported only media pressure to be thin as a significant predictor of compulsive exercise. These findings demonstrate the influence of the media in boys’ and girls’ compulsive exercising, as well as highlight the influence of body shape messages to become more muscular on boys’ compulsive exercise.     

Harnessing the power of ‘us’: A randomized wait-list controlled trial of the 5R shared leadership development program (5RS) in basketball teams

High-quality leadership has been established as a key factor driving a team's competitive advantage. Besides the role of the coach, recent research has emphasized the importance of leadership provided by athletes within a team (i.e., athlete leaders). To unlock the potential benefits of athlete leadership, the development of leaders is therefore essential. The 5R Shared Leadership Program (5R^S) aims to identify promising leaders within a team, on different athlete leadership roles, both on and off the field. After the appointment of the leaders, their identity leadership skills to build and strengthen a sense of ‘we’ and ‘us’ are further developed. The design of the present research consisted of a randomized wait-list controlled trial to test the effectiveness of a train-the-trainer approach to develop shared leadership within teams (i.e., 5R^S). We tracked 16 competitive basketball teams throughout a competitive season. While eight teams (four female and four male teams) received 5R^S during the first half of the season (i.e., experimental condition), the other eight teams received 5R^S during the second half of the season (i.e., wait-list control condition). Our findings highlight 5R^S's capacity to develop athlete leaders' ability to create a shared sense of ‘us’, build a stronger team identification, enhance the available social support in the team, help players to remain motivated and confident in their team's abilities, and nurture players' health. Moreover, 5R^S appeared to achieve this impact by using a train-the-trainer approach, regardless of whether the intervention was delivered during the first or second half of the season, and with generally consistent findings amongst male and female teams. The present study both advances the current field on in-group leadership development, and provides practitioners with guidance on how and when to apply 5R^S with the aim of improving team functioning and athletes' health.     

Refreshing Older Adults’ Driving Skills (ROADSkills): A randomized controlled trial examining the effect of video feedback

ObjectivesThis study evaluated the effectiveness of a personalized video-based driver training program on the behind-the-wheel skills of community-dwelling older adults.MethodIn this randomized controlled trial (RCT), 80 older drivers [mean age (SD) = 71.0 (3.9)] were randomly assigned to view one of two educational videos: 1) personalized video feedback on their driving (n = 40) or 2) a generic video on aging-in-place (n = 40). The primary outcome, the total number of errors accrued in a 30-minute standardized on-road evaluation, was analyzed at baseline and 4 weeks after watching the assigned video. On-road evaluations were video-recorded and scored by a blinded rater. Self-report measures of driving abilities, behaviors, and comfort were also compared.ResultsAt the 4-week follow-up, the mean difference in the number of on-road performance errors [mean (95% CI) = -12.0 (-16.6, −7.4), p < 0.001] favored the intervention group compared to controls, with significant improvements across multiple domains: vehicle control [mean (95% CI) = -4.8 (-8.1, −1.5), p < 0.01], observing the roadway [mean (95% CI) = -5.5 (-8.4, −2.6), p < 0.001], and compliance with traffic rules [mean (95% CI) = -1.3 (-2.3, −0.2), p < 0.05]. Within-group change on behind-the-wheel errors was significant for the intervention group [mean (95% CI) = -10.3 (-13.5, −7.1), p < 0.001], but not for the control group [mean (95% CI) = 1.7 (-1.6, 4.9), p > 0.05]. No significant differences were found on the self-report measures.DiscussionA novel, video-based approach that provided personalized feedback to older drivers significantly reduced behind-the-wheel errors 4-weeks post-intervention. Changes in self-reported driving behaviors and abilities were not significant. Future research will examine the long-term effects of this approach on older adults’ actual and perceived driving abilities.     

The effects of four days of intensive mindfulness meditation training (Templestay program) on resilience to stress: a randomized controlled trial

The interest in mindfulness meditation interventions has surged due to their beneficial effects in fostering resilience and reducing stress in both clinical and non-clinical populations. However, the relaxation benefits that may occur while practicing mindfulness meditation and long-term benefits of these interventions remain unclear. Fifty-one participants were recruited and randomized into the experimental and control groups, which underwent 4 days of Intensive Meditation (Templestay program, n = 33) and Relaxation (Control, n = 18), respectively. The self-report measures of Cognitive and Affective Mindfulness Scale-Revised (CAMS) and the modified Korean version of the Resilience Quotient Test (RQT) were administered pre-, post- and 3 months after the intervention to measure participants’ levels of mindfulness and resilience. Participants in both the Templestay program and Control groups showed significant increases in their scores on CAMS and RQT after completing the program. During the 3-month follow-up, a significant interaction effect of the intervention method and time was revealed for the individuals’ CAMS and RQT scores. Our findings support the hypothesis that while relaxation practices may have certain stress reduction effects, the effects are predominantly mediated by the mindfulness meditation practice. Furthermore, the long-term benefits of increased resilience observed in the Templestay program group suggest that the practice may be a possible treatment strategy in clinical populations, such as patients with depression and anxiety.     

Can dialectical behavior therapy be learned in highly structured learning environments? Results from a randomized controlled dissemination trial

This study evaluated the efficacy of methods of training community mental health providers (N = 132) in dialectical behavior therapy (DBT) distress tolerance skills, including (a) Linehan's (1993a) Skills Training Manual for Borderline Personality Disorder (Manual), (b) a multimedia e-Learning course covering the same content (e-DBT), and (c) a placebo control e-Learning course (e-Control). Participants were randomized to a condition, and the training took place in a highly structured and controlled learning environment. Assessments were completed at baseline, post-training, and 2, 7, 11, and 15 weeks following training. The results indicate that one or both of the active DBT conditions outperformed the control condition on all outcomes except motivation to learn and use the treatment. While clinicians preferred e-DBT over the Manual and found it more helpful and engaging, the active DBT conditions generally did not differ on the primary outcomes of knowledge and self-efficacy, with the exception that e-DBT significantly outperformed the Manual on knowledge at the 15-week follow-up. E-DBT also produced the highest rate of applying and teaching the newly learned skills in clinical practice. Overall, results from this study support the efficacy of e-Learning in disseminating knowledge of empirically supported treatments to clinicians, while also indicating that treatment manuals can be effective training tools.     

Mothers’ self-reported emotion dysregulation: A potentially valid method in the field of infant mental health

In the current study, we evaluated the extent to which mothers reported emotion dysregulation on the Difficulties with Emotion Regulation Questionnaire (DERS) (a) converged with physiological indices of emotion dysregulation while parenting, (b) correlated with maternal sensitivity, and (c) predicted infant attachment disorganization and behavior problems in a sample of 259 mothers and their infants. When infants were 6 months old, mothers’ physiological arousal and regulation were measured during parenting tasks and mothers completed the DERS. Maternal sensitivity was observed during distress-eliciting tasks when infants were 6 and 14 months old. Infant attachment disorganization was assessed during the Strange Situation when infants were 14 months old and mothers reported on infants’ behavior problems when infants were 27 months old. Mothers who reported greater emotion regulation difficulties were more physiologically dysregulated during stressful parenting tasks and also showed lower levels of maternal sensitivity at 6 months. Mother-reported dysregulation predicted higher likelihood of infant attachment disorganization and more behavior problems. Results suggest that the DERS is a valid measure of maternal emotional dysregulation and may be a useful tool for future research and intervention efforts aimed toward promoting positive parenting and early child adjustment.     

The effects of different themes of self-disclosure on health outcomes in cancer patients—A meta-analysis

Self-disclosure (SD) is a common psychological intervention that involves expressing the patient's feelings and thoughts. The purpose of this study was to assess the effectiveness of different themes of SD on cancer patients. We searched eight databases including PubMed, Cochrane Library Trials, Web of Science, CINAHL, Medline, EMBASE, CNKI and Wanfang from inception to July 2022. Other sources included clinical data registers. The Cochrane Collaboration's tool was used to assess the risk of bias in the included studies. RevMan Analysis software 5.3 was used for data analysis. The protocol of this meta-analysis has been registered on PROSPERO (CRD42022339661). Twenty-two RCTs studies were included. The pooled results demonstrated that self-regulation self-disclosure (SRD) had significant effects on patients' sleep quality, benefit-finding, anxiety and quality of life (QOL), whereas emotional disclosure (ED) did not. Furthermore, enhanced self-regulation self-disclosure (ESRD) or cancer-related self-disclosure (CD) significantly improved patients' QOL, although health education self-disclosure (HED) and positive self-disclosure (PD) did not. Our study suggests that different themes of SD have varied effects on patients, but it remains unclear which themes to use at what point in time. Future research should investigate what themes of SD are adopted at different points in time and the duration of different periods.     

Who benefits from emotional expression? An examination of personality differences among gynaecological cancer patients participating in a randomized controlled emotional disclosure intervention trial

The present study examined the role of neuroticism and extraversion in the effects of written emotional disclosure in patients diagnosed with gynaecological cancer. It was hypothesized that high levels of neuroticism would be associated with an increase in distress after emotional disclosure as mediated by heightened negative affect and avoidance post-disclosure. Conversely, we expected high extraversion to be associated with decreased distress as mediated by heightened positive moods and a decrease in avoidance. Eighty-eight participants were randomly assigned to participate in an expressive writing task versus a control writing task. Distress and avoidance were assessed at baseline and 6 months post-writing. Negative and positive mood were assessed immediately following writing. Multiple regression confirmed that neuroticism but not extraversion moderates the effects of emotional disclosure on distress, however no significant mediating relationships were found.
