Acute Bouts of Exercising Improved Mood, Rumination and Social Interaction in Inpatients With Mental Disorders

Association between physical activity and mental health problems among children and adolescents: A moderated mediation model of emotion regulation and gender

BACKGROUND

Studies suggests a correlation between physical activity and mental health, particularly in children and adolescents. However, the specific mechanisms underlying this relationship is not fully understood. This study was designed to investigate the potential mediating role of emotion regulation and the moderating influence of gender through a moderated mediation model.

METHODS

A sample size of 4763 students (mean age = 11.12 ± 1.48 years, 52.8 % females) from seven schools in Shenzhen, China, was recruited during the period of October to November 2023. The participants were administered self-reported questionnaires assessing physical activity, mental health, and emotion regulation. The moderated mediation model was analyzed. Data analysis was conducted using SPSS 25.0.

RESULTS

The results indicate a negative correlation between physical activity and mental health problems (all p < 0.001). This association was partially mediated by both cognitive reappraisal and expressive suppression (all p < 0.001). Additionally, gender significant moderated the path between physical activity and emotion regulation, specifically cognitive reappraisal (p < 0.001) and expressive suppression (p < 0.01).

LIMITATIONS

As a result of the cross-sectional design, no causal relationship could be established, and measurement bias should be noted.

CONCLUSION

Physical activity is found to have a positive effect on the mental health problem of children and adolescents with emotion regulation serve as a partial mediator in the relationship. Additionally, in the mediation model, gender influences the first half of the path.

Effects of an intervention combining physical activity and components of Amygdala and Insula Retraining (AIR) on sleep and working memory among older male adults

Background

Older individuals are at a particular risk of sleep disorders, a loss of cognitive and emotional control, and a poor quality of life. Pharmaceutical therapy for these conditions is commonplace but has not been particularly effective, and relatively little research exists for their treatment using non-pharmacological approaches. The effectiveness of Physical Activity plus selected components of Amygdala and Insula Retraining (PAAIR) was tested to improve sleep quality, depression, working memory, and emotion regulation among older males.

Methods

This was a parallel, randomized control trial. The study was conducted in-person among 40 older Iranian men (M age: 65.78, SD = 2.41). The participants were randomly assigned with equal allocation to either the PAAIR or a control condition. Both interventions were conducted in-person over 12 weeks. The participants met twice weekly for 45-minute sessions at a local elderly training and rehabilitation center. All participants completed measurements for sleep quality, depressive symptoms, working memory, and emotion regulation at baseline, 12 weeks (immediately after the intervention), and 8 weeks later.

Results

Among the 36 individuals who finished the study, their sleep quality, working memory, and emotion regulation improved, and their depressive symptoms were reduced from baseline to 12 weeks (post-intervention) and 8 weeks later; these effects were seen even more so for the PAAIR group compared to the control group, with large to extremely large effect sizes.

Conclusion

The findings suggest that PAAIR has the potential to enhance sleep quality, cognitive function, and emotion regulation and reduce depressive symptoms among older men, thus contributing to their quality of life and mental health.

Effects of physical activity on anxiety levels in college students: mediating role of emotion regulation

Objectives

To explore the effects of physical activity on anxiety levels in college students, as well as to examine the mediating role of emotion regulation.

Methods

A convenience sample of 1,721 college students from Shanghai, Jiangsu, Shandong, Guangxi, and Hunan was used to conduct an evaluation and a survey through the Physical Activity Rating Scale (PARS-3), the Anxiety Self-Rating Scale (SAS), and the Emotion Regulation Scale (ERQ).

Results

College students' anxiety level, cognitive reappraisal, and expression inhibition scores were (44.72 ± 10.37), (30.16 ± 6.51), and (16.96 ± 4.99), respectively. There were significant grade and physical activity level differences in anxiety levels and cognitive reappraisal, and significant gender and physical activity level differences in expression inhibition among college students. Process model 4 mediated effect regression analysis showed that physical activity had a significant positive effect on cognitive reappraisal (R 2 = 0.14, β = 0.04, P < 0.001), and physical activity did not have a significant expression inhibition effect (R 2 = 0.17, β = 0.01, P = 0.27). Physical activity (β = -0.03, P = 0.012), cognitive reappraisal (β = -0.59, P < 0.001), and expression inhibition had a significant effect on (β = 0.57, P < 0.001) anxiety levels (R 2 = 0.37). In the model effect relationship, the direct and indirect effects of physical activity on anxiety levels were -0.028 and -0.019, respectively.

Conclusion

Physical activity has a significant negative effect on college students' anxiety levels. Cognitive reappraisal is a mediating variable for the effect of physical activity on anxiety levels. The higher the level of physical activity and the higher the intensity of the activity, the lower the level of anxiety.

Temporal Associations Between Specific Depressive Symptoms and Physical Inactivity in Middle Aged and Older Adults

Being physically inactive can worsen mental health. Physical inactivity and depression are associated, but the temporal precedence and underlying mechanism are unclear; symptoms affecting future physical activity may not be the same symptoms as those associated with and affected by it. We used large European cohort (Survey of Health, Ageing, and Retirement in Europe, SHARE, N = 124, 526) to study temporal associations between physical inactivity and individual depressive symptoms. Multivariate regression with robust standard errors were used to analyze how physical inactivity is associated with later depression and how depressive symptoms predict later physical inactivity. After adjusting the models for demographics, other health behaviors, BMI, and chronic diseases, physical inactivity was prospectively associated with 10 of the 12 depressive symptoms and 7 of the 12 baseline depressive symptoms were prospectively associated with physical inactivity. These findings were robust for adjusting for antidepressant medication. Age-stratified analyses suggested that the associations between physical inactivity and depressive symptoms were independent of age. Omitting the most influential symptom, lack of enjoyment, from the sum score attenuated the association by 13% in the longitudinal and by 26% in the cross-sectional analyses. These findings suggest that physical inactivity and depression are bidirectionally associated even at symptom-level.

Sleep disturbances and psychological well-being among military medical doctors of the Swiss Armed Forces: study protocol, rationale and development of a cross-sectional and longitudinal interventional study

Background

Compared to civilians and non-medical personnel, military medical doctors are at increased risk for sleep disturbances and impaired psychological well-being. Despite their responsibility and workload, no research has examined sleep disturbances and psychological well-being among the medical doctors (MDs) of the Swiss Armed Forces (SAF). Thus, the aims of the proposed study are (1) to conduct a cross-sectional study (labeled 'Survey-Study 1') of sleep disturbances and psychological well-being among MDs of the SAF; (2) to identify MDs who report sleep disturbances (insomnia severity index >8), along with low psychological well-being such as symptoms of depression, anxiety and stress, but also emotion regulation, concentration, social life, strengths and difficulties, and mental toughness both in the private/professional and military context and (3) to offer those MDs with sleep disturbances an evidence-based and standardized online interventional group program of cognitive behavioral therapy for insomnia (eCBTi) over a time lapse of 6 weeks (labeled 'Intervention-Study 2').

Method

All MDs serving in the SAF (N = 480) will be contacted via the SAF-secured communication system to participate in a cross-sectional survey of sleep disturbances and psychological well-being ('Survey-Study 1'). Those who consent will be provided a link to a secure online survey that assesses sleep disturbances and psychological well-being (depression, anxiety, stress, coping), including current working conditions, job-related quality of life, mental toughness, social context, family/couple functioning, substance use, and physical activity patterns. Baseline data will be screened to identify those MDs who report sleep disturbances (insomnia severity index >8); they will be re-contacted, consented, and randomly assigned either to the eCBTi or the active control condition (ACC) ('Intervention-Study 2'). Individuals in the intervention condition will participate in an online standardized and evidence-based group intervention program of cognitive behavioral therapy for insomnia (eCBTi; once the week for six consecutive weeks; 60-70 min duration/session). Participants in the ACC will participate in an online group counseling (once the week for six consecutive weeks; 60-70 min duration/session), though, the ACC is not intended as a bona fide psychotherapeutic intervention. At the beginning of the intervention (baseline), at week 3, and at week 6 (post-intervention) participants complete a series of self-rating questionnaires as for the Survey-Study 1, though with additional questionnaires covering sleep-related cognitions, experiential avoidance, and dimensions of self-awareness.

Expected outcomes

Survey-Study 1: We expect to describe the prevalence rates of, and the associations between sleep disturbances (insomnia (sleep quality); sleep onset latency (SOL); awakenings after sleep onset (WASO)) and psychological well-being among MDs of the SAF; we further expect to identify specific dimensions of psychological well-being, which might be rather associated or non-associated with sleep disturbances.Intervention-Study 2: We expect several significant condition-by-time-interactions. Such that participants in the eCBTi will report significantly greater improvement in sleep disturbances, symptoms of depression, anxiety, stress reduction both at work and at home (family related stress), and an improvement in the overall quality of life as compared to the ACC over the period of the study.

Conclusion

The study offers the opportunity to understand the prevalence of sleep disturbances, including factors of psychological well-being among MDs of the SAF. Further, based on the results of the Intervention-Study 2, and if supported, eCBTi may be a promising method to address sleep disturbances and psychological well-being among the specific context of MDs in the SAF.

Psychiatric Characteristics, Symptoms of Insomnia and Depression, Emotion Regulation, and Social Activity among Swiss Medical Students

Background: Almost by default, young adult students are at increased risk of suffering from mental health issues, and this holds particularly true for medical students. Indeed, compared to the general population and non-medical students, medical students report higher scores for symptoms of depression. For Swiss medical students, research on the associations between psychiatric characteristics and symptoms of depression and insomnia, including cognitive-emotional processes and social activity, has been lacking so far. Given this, the aims of the present study were to relate self-declared psychiatric characteristics to symptoms of depression, insomnia, emotion regulation, and social activity. Methods: A total of 575 medical students (mean age: 22.4 years; 68.9% females) completed an online survey covering sociodemographic information (age and gender), study context (year of study), self-declared psychiatric characteristics and symptoms of depression, insomnia, emotion regulation (cognitive reappraisal vs. emotion suppression), and social activity. Data on insomnia sum scores and categories of historical samples (862 non-medical students and 533 police and emergency response service officers) were used for comparison. Results: Of the 575 participants, 190 participants (33%) self-declared psychiatric issues, such as major depressive disorder; anxiety disorders, including PTSD and adjustment disorders; eating disorders; ADHD; or a combination of such psychiatric issues. Self-reporting a psychiatric issue was related to higher symptoms of depression and insomnia and lower symptoms of social activity and cognitive reappraisal (always with significant p-values and medium effect sizes). Compared to historical data for non-medical students and police and emergency response service officers, medical students reported higher insomnia scores. In a regression model, current self-declared psychiatric issues, female gender, higher scores for insomnia, and lower scores for social activity were associated with higher scores for depression. Conclusions: Among a sample of Swiss medical students, the occurrence of self-declared psychiatric issues was associated with higher scores for depression and insomnia and lower cognitive reappraisal and social activity. Further, insomnia scores and insomnia categories were higher when compared to non-medical students and to police and emergency response service officers. The data suggest that medical schools might introduce specifically tailored intervention and support programs to mitigate medical students' mental health issues. This holds particularly true for insomnia, as standardized and online-delivered treatment programs for insomnia (eCBTi) are available.

Affective Responses to Acute Exercise: A Meta-Analysis of the Potential Beneficial Effects of a Single Bout of Exercise on General Mood, Anxiety, and Depressive Symptoms

OBJECTIVE

Acute exercise elicits various biobehavioral and psychological responses, but results are mixed with regard to the magnitude of exercise-induced affective reactions. This meta-analysis examines the magnitude of general mood state, anxiety, and depressive symptom responses to acute exercise while exploring exercise protocol characteristics and background health behaviors that may play a role in the affective response.

METHODS

A total of 2770 articles were identified from a MEDLINE/PubMed search and an additional 133 articles from reviews of reference sections. Studies had to have measured general mood before the acute exercise bout and within 30 minutes after exercise completion. Effect sizes were estimated using Hedges' g , with larger values indicating improvement in the outcome measure.

RESULTS

A total of 103 studies were included presenting data from 4671 participants. General mood state improved from preexercise to postexercise ( g = 0.336, 95% confidence interval [CI] = 0.234-0.439). Anxiety ( g = 0.497, 95% CI = 0.263-0.730) and depressive symptoms ( g = 0.407, 95% CI = 0.249-0.564) also improved with exercise. There was substantial and statistically significant heterogeneity in each of these meta-analyses. This heterogeneity was not explained by differences in participants' health status. Meta-regression analyses with potential moderators (intensity of exercise, mode of exercise, usual physical activity level, or weight status of participants) also did not reduce the heterogeneity.

CONCLUSION

This meta-analysis shows significantly improved general mood, decreased anxiety, and lower depressive symptoms in response to an acute bout of exercise. There was substantial heterogeneity in the magnitude of the effect sizes, indicating that additional research is needed to identify determinants of a positive affective response to acute exercise.

Integrative Functions of the Hypothalamus: Linking Cognition, Emotion and Physiology for Well-being and Adaptability

Background

The hypothalamus, a small yet crucial neuroanatomical structure, integrates external (e.g., environmental) and internal (e.g., physiological/hormonal) stimuli. This integration governs various physiological processes and influences cognitive, emotional, and behavioral outcomes. It serves as a functional bridge between the nervous and endocrine systems, maintaining homeostasis and coordinating bodily functions.

Summary

Recent advancements in the neurobiology of the hypothalamus have elucidated its functional map, establishing a causal relationship between its responses-such as respiration, sleep, and stress-and various physiological processes. The hypothalamus facilitates and coordinates these complex processes by processing diverse stimuli, enabling the body to maintain internal balance and respond effectively to external demands. This review delves into the hypothalamus's intricate connections with cognition, emotion, and physiology, exploring how these interactions promote overall well-being and adaptability.

Key Message

Targeted external stimuli can modulate hypothalamic neuronal activities, impacting the physiological, cognitive, and emotional landscape. The review highlights non-invasive techniques, such as controlled breathing exercises, optimized sleep architecture, and stress management, as potential methods to enhance hypothalamic function. Ultimately, this comprehensive review underscores the multifaceted role of the hypothalamus in integrating signals, maintaining homeostasis, and influencing cognition, emotion, and physiology.

Enjoyment and Affective Responses to Moderate and High-Intensity Exercise: A Randomized Controlled Trial in Individuals with Subsyndromal PTSD

This crossover randomized controlled trial examined the acute psychological effects of a bout of moderate-intensity continuous aerobic exercise (MICE) and a bout of high-intensity functional exercise (HIFE), relative to a no-exercise sedentary control (SED), in participants (N = 21; 15 f; 24.7 ± 9.3 years) with subsyndromal post-traumatic stress disorder (PTSD). Affective state (Energy, Tiredness, Tension, Calmness) was assessed before (Pre), immediately after (Post 0), 20-min after (Post 20), and 40-min after (Post 40) each condition. Affective valence was assessed during each condition, and exercise enjoyment was assessed at Post 0. Enjoyment was significantly greater following HIFE and MICE relative to SED. Energy was significantly increased Post 0 HIFE and MICE but decreased Post 0 SED. Tension was reduced following all conditions and was significantly lower at Post 40 relative to Pre for HIFE, MICE, and SED. Tiredness was significantly reduced at Post 40 relative to Pre following MICE only, while Calmness was significantly lower at Post 40 relative to Pre following MICE and SED. Overall, both exercise conditions were enjoyed to a greater extent than the control, but MICE may provide greater psychological benefits with respect to Calmness and Tiredness. This study is among the first to assess acute changes in affective states relative to various exercise modes in individuals living with subsyndromal PTSD.

Clusters of lifestyle behavioral risk factors and their associations with depressive symptoms and stress: evidence from students at a university in Finland

BACKGROUND

No previous research of university students in Finland assessed lifestyle behavioral risk factors (BRFs), grouped students into clusters, appraised the relationships of the clusters with their mental well-being, whilst controlling for confounders. The current study undertook this task.

METHODS

Students at the University of Turku (n = 1177, aged 22.96 ± 5.2 years) completed an online questionnaire that tapped information on sociodemographic variables (age, sex, income sufficiency, accommodation during the semester), four BRFs [problematic alcohol consumption, smoking, food consumption habits, moderate-to-vigorous physical activity (MVPA)], as well as depressive symptoms and stress. Two-step cluster analysis of the BRFs using log-likelihood distance measure categorized students into well-defined clusters. Two regression models appraised the associations between cluster membership and depressive symptoms and stress, controlling for sex, income sufficiency and accommodation during the semester.

RESULTS

Slightly more than half the study participants (56.8%) had always/mostly sufficient income and 33% lived with parents/partner. Cluster analysis of BRFs identified three distinct student clusters, namely Cluster 1 (Healthy Group), Cluster 2 (Smokers), and Cluster 3 (Nonsmokers but Problematic Drinkers). Age, sex and MVPA were not different across the clusters, but Clusters 1 and 3 comprised significantly more respondents with always/mostly sufficient income and lived with their parents/partner during the semester. All members in Clusters 1 and 3 were non-smokers, while all Cluster 2 members comprised occasional/daily smokers. Problematic drinking was significantly different between clusters (Cluster 1 = 0%, Cluster 2 = 54%, Cluster 3 = 100%). Cluster 3 exhibited significantly healthier nutrition habits than both other clusters. Regression analysis showed: (1) males and those with sufficient income were significantly less likely to report depressive symptoms or stress; (2) those living with parents/partner were significantly less likely to experience depressive symptoms; (3) compared to Cluster 1, students in the two other clusters were significantly more likely to report higher depressive symptoms; and (4) only students in Cluster 2 were more likely to report higher stress.

CONCLUSIONS

BRFs cluster together, however, such clustering is not a clear-cut, all-or-none phenomenon. Students with BRFs consistently exhibited higher levels of depressive symptoms and stress. Educational and motivational interventions should target at-risk individuals including those with insufficient income or living with roommates or alone.

Fostering quality of life in young adults living with multiple sclerosis: a pilot study of a co-created integrated intervention

Introduction

Multiple sclerosis (MS) is generally diagnosed at an early age, making the acceptance of this chronic disease challenging. Research dedicated to young adults with MS (YawMS) is still limited. A biopsychosocial co-created intervention for YawMS integrating social, physical and psychological activities was developed (ESPRIMO intervention) in order to improve the quality of life (QoL) and well-being. This pre-post intervention assessment study examines the feasibility of the ESPRIMO intervention and its signal of efficacy.

Methods

Inclusion criteria were: age 18-45 years, MS diagnosis, Expanded Disability Status Scale score < 3.5. After giving informed consent, YawMS completed a battery of questionnaires, which was repeated after the intervention. The battery included a bespoke feasibility scale, the COOP/WONCA charts, and the Short Form-12 Health Survey (SF-12).

Results

Fifty-three YAwMS were enrolled and 43 (81.1%) completed the intervention. The majority of the sample positively rated the pleasantness, usefulness and feasibility of the intervention. A significant change in the COOP/WONCA "general QoL" chart (t = 3.65; p < 0.01) and SF-12 mental wellbeing component (t = -3.17; p < 0.01) was found.

Discussion

ESPRIMO is an innovative intervention that is feasible; preliminary results show an improvement in QoL and mental wellbeing. Further studies are needed to test its efficacy and evaluate future implementation in health services.Clinical trial registration: ClinicalTrials.gov, NCT04431323.

Physical activity and specific symptoms of depression: A pooled analysis of six cohort studies

BACKGROUND

The association between physical activity (PA) and depression is well-established, but the details that explain this association remain elusive. We examined whether PA is differentially associated with specific symptoms of depression (e.g., cognitive vs somatic symptoms), and whether these associations follow a dose-response pattern with respect to intensity or frequency of PA.

METHODS

Cross-sectional analyses were based on 6 samples of the continuous U.S. National Health and Nutrition Examination Surveys (NHANES) carried out between 2007 and 2018 (n = 28,520). Depressive symptoms were assessed with Patient Health Questionnaire 9 (PHQ-9). Information about PA (vigorous, moderate, and daily commuting by foot or bike) and covariates was self-reported.

RESULTS

After adjusting for education, health behaviors, body-mass index, physical functioning, and all the other depressive symptoms, lower PA was specifically associated with four depressive symptoms: loss of interest/pleasure, feeling down/hopeless, fatigue, and changes in appetite (odds ratios from 0.94 to 0.59). A monotonic dose-response pattern on PA amount was observed only for interest/pleasure and fatigue, and these associations were independent of PA intensity.

LIMITATIONS

Cross-sectional data did not allow us to assess temporal ordering. Both depressive symptoms and PA were self-reported, which may induce bias.

CONCLUSION

Low PA may be linked to depressive symptoms particularly through the symptoms of anhedonia and fatigue. Given that their association with PA amount follows a dose-response pattern and is independent of PA intensity, we hypothesize that behavioral activation and exposure to rewarding experiences might help to explain why PA alleviates depression.

Mindfulness plus physical activity reduces emotion dysregulation and insomnia severity among people with major depression

BACKGROUND

As the disorder progresses, patients with depression suffer from decreased emotional stability, cognitive control and motivation. In the present study, we examined the effectiveness of three interventions on emotion dysregulation and insomnia severity: 1) mindfulness; 2) physical activity, and 3) mindfulness plus physical activity.

METHOD

A total of 50 participants (mean age 33.21 ± 5.72 SD, 59% females) with major depression were randomly assigned to one of the three study conditions. Emotional dysregulation and insomnia severity were assessed at baseline, eight weeks later at study completion, and 4 weeks after that at follow-up.

RESULTS

Emotion regulation and sleep quality improved over time from baseline to study completion and to follow-up. Compared to the mindfulness and physical activity alone conditions, the mindfulness plus physical activity condition led to higher emotion regulation and sleep quality.

CONCLUSION

The combination of physical activity and mindfulness seems to have a beneficial effect on sleep quality and emotion regulation in those with major depression disorder and could be a valuable treatment strategy.

Physical activity and depression of Chinese college students: chain mediating role of rumination and anxiety

Objective

To explore the relationship between physical activity and depression among college students, as well as the mediating role of rumination and anxiety.

Methods

A total of 1,292 Chinese college students were investigated by physical activity questionnaire, rumination scale, self-rating anxiety scale (SAS), and depression scale.

Results

(1) There was a significant negative correlation between physical activity and depression (r = -0.399, p < 0.01), and the direct path of physical activity on depression was significant (β = -0.399, t = -13.374, p < 0.01). (2) Physical activity negatively predicted rumination (β = -0.322, t = -10.440, p < 0.01) and anxiety (β = -0.222, t = -7.089, p < 0.01). Rumination positively predicted anxiety (β = 0.283, t = 9.017, p < 0.01) and depression (β = 0.267, t = 9.046, p < 0.01). Anxiety positively predicted depression (β = 0.262, t = 8.902, p < 0.01). (3) Rumination and anxiety play a significant mediating role between physical activity and depression. The mediating effect involves three paths: physical activity → rumination → depression (the mediating effect value: -0.076); physical activity → anxiety → depression (the mediating effect value: -0.052). Physical activity → rumination → anxiety → depression (the mediating effect value: -0.021).

Conclusion

(1) Physical activity can negatively predict the rumination, anxiety, and depression of college students, which means physical activity can reduce rumination, anxiety, and depression of college students. (2) Physical activity can not only directly affect the depression of college students, but also indirectly affect depression through the independent intermediary role of rumination and anxiety, and the chain mediation of rumination and anxiety.

Better sleep quality and higher physical activity levels predict lower emotion dysregulation among persons with major depression disorder

BACKGROUND

People with Major Depression Disorders (MDD) often complain about sleep problems and experience emotion dysregulation. Prior research suggests physical activity can improve both sleep quality and emotional control. However, there is limited research on emotion regulation and the impact of physical activity and sleep in this population.

OBJECTIVES

The present study examined the relationships between sleep quality, emotion regulation, and physical activity levels among patients with MDD.

METHODS

The sample consisted of 118 patients with MDD (mean age: 31.85 years) who completed questionnaires on sleep quality, physical activity, emotion regulation, and depression.

RESULTS

Results showed that more sleep problems were associated with worse emotion dysregulation, and more physical activity was associated with fewer sleep problems and less emotion dysregulation. Furthermore, physical activity and sleep quality significantly predicted emotion dysregulation, with physical activity being the stronger predictor.

CONCLUSIONS

Results from this study suggest that individuals with MDD who are able to engage in physical activity and get better sleep could experience emotional regulation benefits.

[Formula: see text]Is active video gaming associated with improvements in social behaviors in children with neurodevelopmental disorders: a systematic review

Active video gaming (AVG) is a way that children with neurodevelopmental disorders can participate in social play and could be associated with improvements in social behaviors. However, limited research has investigated if AVG is associated with improvements in social behaviors in children and adolescents with neurodevelopmental disorders. A systematic literature search was conducted in Medline, Embase, Psycinfo, Cinahl, and Eric, Web of Science, and Scopus. Three main concepts were searched: exergaming, neurodevelopmental disorders, and social behaviors. Keywords and subject headings were used for each concept. 3080 articles were identified in the initial search in 2019; in January 2021, 167 additional articles were identified. Of these, 8 studies with 242 children with autism spectrum disorder, cerebral palsy, or developmental coordination disorder were included in this review. Six studies reported that participation in AVG was associated with improved social functioning, social interaction, emotional well-being, and social/emotional skills in children with ASD, CP, and DCD. In contrast, two studies that included children diagnosed with ASD did not find any association between AVG participation and social behaviors. The findings of this systematic review suggest that participation in an AVG intervention may be associated with improved social behaviors in children and adolescents with ASD, CP, and DCD. However, due to the limited number of studies included, this finding must be interpreted with caution. Future research is needed that examines the treatment fidelity of AVG in improving social behavior skills in children with neurodevelopmental disorders and the generalizability of these skills to real-life social situations.

Sluggish Cognitive Tempo among Iranian Children and Adolescents: A Validation Study of the Farsi Child and Adolescent Behavior Inventory (CABI)–Parent Version

Background: Sluggish cognitive tempo (SCT), recently renamed cognitive disengagement syndrome (CDS), is a set of behavioral symptoms that includes excessive daydreaming, mental confusion and fogginess, being lost in one’s thoughts, and slowed behavior and thinking. Symptoms of SCT show overlap with a broad range of other symptoms such as attention-deficit/hyperactivity disorder inattention, anxiety, and depression, or oppositional defiant disorder (ODD). To measure SCT, one of the optimal measures is the Child and Adolescent Behavior Inventory (CABI). Here, we report the psychometric properties of the Farsi version of the CABI Parent Version, including the CABI SCT scale and its subscales. Methods: The participants were the parents of 209 children and adolescents (53.9% girls; ages 8–19 years; M_age = 14.23, SD_age = 2.72). Parents completed the SCT, ADHD inattention (ADHD-IN), ADHD-hyperactivity/impulsivity (ADHD-HI), oppositional defiant disorder (ODD), limited prosocial emotions (callous-unemotional (CU) traits), anxiety, depression, social impairment, and academic impairment scales of the Child and Adolescent Behavior Inventory (CABI). Parents also completed four dimensions of the Strengths and Difficulties Questionnaire (SDQ: emotional problems; conduct problems; peer problems; prosocial behavior), and five dimensions of the Kidscreen questionnaire (physical health; psychological well-being; autonomy and parental well-being; peers and social support; school environment). Results: SCT symptoms demonstrated strong discriminant validity from the ADHD-IN symptoms. SCT showed stronger first-order and unique associations than ADHD-IN with anxiety, depression, and ODD, whereas ADHD-IN showed stronger first-order and unique associations than SCT with ADHD-HI, CU, and social and academic impairment. Further, SCT showed stronger first-order and unique associations than ADHD-IN with more emotional problems, peer problems, and with lower prosocial behavior, as assessed with the SDQ. Higher scores for SCT were associated with lower psychological well-being, autonomy and parental relations, and lower peer and social support, as assessed with the Kidscreen. Higher ADHD-IN scores were associated with lower peer and social support, and a lower school environment. Conclusions: The Farsi version of the CABI–Parent Version has very good psychometric properties for assessing SCT and other dimensions of psychopathology/impairment and replicates the findings from similar studies with children and adolescents from South Korea, Spain, Turkey, and the United States. Accordingly, the present study provides further support of the transcultural validity of the sluggish cognitive tempo construct.

The relationship between physical exercise and mobile phone addiction among Chinese college students: Testing mediation and moderation effects

Background

During the COVID-19 pandemic, suspensions of activities and long periods of self-isolation led to a sharp increase in excessive use of mobile phones, which sparked public concern about mobile phone addiction (MPA). In recent years, more and more attention has been paid to physical exercise as a protective effect of MPA. However, more studies are needed to reveal this relationship and the exact mechanisms, based on which this study tested the mediating and moderating roles of self-control, rumination, psychological distress, and loneliness between physical exercise and MPA.

Methods

In this cross-sectional study, primary data was collected by questionnaire from 1,843 college students (19.75 ± 1.3) from five universities in Sichuan Province in Mainland China. Mobile Phone Addiction Tendency Scale (MPATS), Physical Activity Rating Scale-3 (PARS-3), Self-Control Scale (SCS), Ruminative Response Scale (RRS), Depression Anxiety Stress Scale-21 (DASS-21), and UCLA Loneliness Scale (UCLA-20) were investigated. The mediating models were examined using SPSS PROCESS macro 3.3 software, in which the mediation variables were self-control, rumination, and psychological distress, and the moderation was loneliness. Gender, major, and grade were included as control variables.

Result

Self-control, rumination, and psychological distress played a simple mediating role between physical exercise and MPA. Moreover, not only self-control and rumination but also self-control and psychological distress played the chain mediating roles between physical exercise and MPA. The chain pathways were moderated by loneliness. Specifically, the effect was more substantial among college students with higher loneliness.

Conclusion

The conclusions corroborate and clarify that self-control, rumination, and psychological distress mediated the association between physical exercise and MPA, and the mediation effects were moderated via loneliness. This present study advanced our understanding of how and when college students’ physical exercise was related to MPA. It also illustrates that educators and parents should pay more attention to college students’ physical exercise.

PE augmented mindfulness: A neurocognitive framework for research and future healthcare

Various well-controlled studies have suggested that practitioners in mindfulness can be prone to patient drop-out (e.g., due to chronic stress, pathology, cognitive reactivity), despite researchers having identified the underlying mechanisms that link mindfulness to mental health. In this article, a framework for physical exercise (PE) augmented mindfulness is proposed, which posits that consistently practiced PE before meditation can support (early-stage) mindfulness. Neurocognitive research shows PE (aerobic exercises or yoga) and mindfulness to impact similar pathways of stress regulation that involve cognitive control and stress regulation, thereby supporting the proposed synergistic potential of PE augmented mindfulness. Research focused on the psychophysiological impact of PE, showed its practice to promote short-term neurocognitive changes that can promote both cognitive control and the attainment of mindful awareness (MA). In order to chart dose responses required for protocol development, further research will be presented. Together these findings are discussed in light of future research on this multidisciplinary topic, protocol development, mindful walking, and further application in healthcare and beyond.

Temporal associations between objectively measured physical activity and depressive symptoms: An experience sampling study

Background

This study aimed to examine the relationship between the timing of physical activity and within-individual differences in depressive symptoms, positive affect, and negative affect in individuals with different baseline levels of depressive symptoms.

Methods

Experience sampling methodology (ESM) was used to measure real-time depressive symptoms, positive affect, and negative affect in a convenience sample of 78 healthy adults (aged M = 25.46 years, SD = 6.18; 57 females) five times per day for 14 days. We measured physical activity throughout the 14 days by using activity sensors. Baseline levels of depressive symptoms were assessed with the PHQ-9 to build subgroups with low vs. mild-moderate depressive symptoms.

Results

Physical activity predicted decreased depressive symptom levels, negative affect, and increased positive affect. Associations were stronger for individuals with higher baseline levels of depressive symptoms and for physical activity between 0 and 30 min compared to physical activity between 30 and 180 min before the mood rating. Conversely, levels of depressive symptoms, positive and negative affect did not predict physical activity.

Limitations

The convenience sample may not have been representative of the general population or people with depression. Accelerometers may not have detected some types of physical activities such as bicycling. Causality could not be inferred because of the observational study design.

Conclusion

Individuals with higher levels of depressive symptoms may benefit from physical activity. While the effects were strongest for physical activity immediately before the mood ratings, the effects were in the same direction for up to 3 h before the mood ratings.

Benefits, Risks and Gender Differences in Sport, and Exercise Dependence: Key Role of Alexithymia

The literature has long highlighted the benefits of sport, but too much sport could indicate a dependence without a substance, namely exercise dependence. The literature has only recently investigated this issue and therefore several questions are open, particularly with regard to psychopathological significance and gender differences. The aim of this paper is to investigate whether young subjects (M = 20 years) with a risk of exercise dependency and non-dependent symptomatic display other behavioural and psychological suffering and discomforts, or whether such an investment in physical activity is compatible with a framework of relative well-being; and if there are differences related to gender. A total of 396 subjects were involved in this study. Exercise Dependence Scale, Toronto Alexithymia Scale, Subjective Happiness Scale, Satisfaction with Life Scale and an ad hoc questionnaire with information relating to the consumption of alcohol, soft and hard drugs, quality of sleep and nutrition, affective and friendship relationships, hobbies, presence of psychological or physical disorders, motivations for sporting activity, and any traumatic experiences were used. With regard to the Exercise Dependence Scale (EDS), the prevalence of subjects at risk of exercise dependence was 1.5% and that of non-dependents symptomatic was 31.3%. Considering only men, the percentage of subjects at risk of exercise dependence rose to 3% and that of non-dependents symptomatic to 47.9%. Our data support the hypothesis that the risk of exercise dependence and the symptomatic condition without dependence can occur in situations of relative well-being (happiness, satisfaction, relationships) without significant associations with other problematic behaviours. Modest consumption of soft drugs is reported in non-dependent symptomatic subjects. The hypothesis of increased levels of alexithymia is confirmed but limited to the male gender. Gender differences are confirmed in the frequency and motivation to practice sport and in the risk of dependence. It is important that the assessment of addiction risk is integrated with the assessment of alexithymia and personal and social resources over time.

Acute aerobic exercise and attentional focus influence the self-positivity bias in emotional evaluation. Evidence from an experimental study

The influence of aerobic exercise, as a possibly mood-enhancing experience, was investigated for its effect on emotional evaluation of self- vs. other-related emotional (e.g., my/his joy) or neutral (e.g., my/his notes) stimuli. N=30 participants (healthy, female novices, i.e., with no regular, dedicated training schedule) performed four separate sessions of moderate aerobic exercise (22 min of cycling at 60-70% HRmax). Attentional focus was manipulated across exercise bouts (internal focus vs. external focus vs. no instructed attention focus vs. control condition consisting of no exercise and no instructed attention focus). Emotional evaluation of verbal stimuli was assessed 10 minutes after each exercise bout. Exercise increased self-reported positive affect compared to the inactive control condition regardless of attentional focus. Exercising without instructed attentional focus led to faster reaction times in the emotional evaluation task compared to the inactive control condition. Instructed internal or external attentional focus did not affect evaluations (number of valence-congruent responses) or reaction times compared to the no-exercise control condition. Self-reported internal attentional focus during cycling was associated with a subsequently stronger, and in the case of an external focus with a subsequently rather reduced self-positivity bias in the evaluation of self-related, positive vs. other-related positive words.

[Enjoying Sports and Movement in Mental Illness]

Enjoying Sports and Movement in Mental Illness Abstract. Sports and exercise therapy is an effective complemant in the treatment of major depression. The recommendations of at least 150 minutes of moderate or 75 minutes of intensive physical activity per week should be met to achieve positive effects of physical activity. In addition, individual needs and the physical health conditions must be considered in the planning and implementation, so that exercise will be enjoyed in the long term.

Physiotherapy and Physical Activity as Factors Improving the Psychological State of Patients With Cancer

Physiotherapy in oncology is a process closely related to cancer treatment methods. Rehabilitation is based on physical activity in various forms involving the musculoskeletal system but also affects the emotional state. Physical activity influences physical and psychological well-being of people undergoing oncological treatment, in the course of which the most common psychiatric disorders are depression, substance use disorder, sleep disorders, fatigue syndrome, resulting in worsening of the quality of life. Difficulties in implementing physical exercise in cancer patients pose a challenge to treatment teams.

The relationship between internalizing problems and acute exercise duration in children with attention-deficit/hyperactivity disorder: The role of frontal alpha asymmetry

BACKGROUND

Frontal alpha asymmetry (FAA) has been associated with the regulation of certain types of internalizing psychopathologies, and is affected by acute aerobic exercise (AE). However, no previous studies have examined the association between FAA and internalizing problems or the effects of acute exercise on FAA in children with ADHD.

AIMS

This study had two objectives. First, it aimed to examine the relationship between FAA and internalizing behaviors in children with ADHD. Second, it sought to investigate the differential effects of acute AE (30 and 50 min) on FAA.

METHOD

Participants were assigned to one of the following three groups: 50 min of AE, 30 min of AE, and a control group. Resting electroencephalogram (EEG) data were recorded before and after their respective treatments. EEG data from 43 participants were analyzed to investigate the association between pre-test FAA and internalizing problems as assessed by Child Behavior Checklist scores. Additionally, EEG data from 46 participants were analyzed to examine the effects of acute AE on post-test FAA while controlling for pre-test FAA.

RESULTS

Pre-test FAA was found to be significantly negatively associated with internalizing problems, with both hemispheres contributing to this association. Regarding the effects of acute exercise, the 50-minute AE group had highest post-test FAA, reflected by the increased relative left-side frontal activity.

CONCLUSIONS

These findings suggest that FAA is a biological marker of internalizing symptoms in children with ADHD, and a 50-minute session of AE can effectively modulate FAA.

Social media and smartphone app use predicts maintenance of physical activity during Covid-19 enforced isolation in psychiatric outpatients

There is growing concern that the social and physical distancing measures implemented in response to the Covid-19 pandemic may negatively impact health in other areas, via both decreased physical activity and increased social isolation. Here, we investigated whether increased engagement with digital social tools may help mitigate effects of enforced isolation on physical activity and mood, in a naturalistic study of at-risk individuals. Passively sensed smartphone app use and actigraphy data were collected from a group of psychiatric outpatients before and during imposition of strict Covid-19 lockdown measures. Data were analysed using Gaussian graphical models: a form of network analysis which gives insight into the predictive relationships between measures across timepoints. Within-individuals, we found evidence of a positive predictive path between digital social engagement, general smartphone use, and physical activity-selectively under lockdown conditions (N = 127 individual users, M = 6201 daily observations). Further, we observed a positive relationship between social media use and total daily steps across individuals during (but not prior to) lockdown. Although there are important limitations on the validity of drawing causal conclusions from observational data, a plausible explanation for our findings is that, during lockdown, individuals use their smartphones to access social support, which may help guard against negative effects of in-person social deprivation and other pandemic-related stress. Importantly, passive monitoring of smartphone app usage is low burden and non-intrusive. Given appropriate consent, this could help identify people who are failing to engage in usual patterns of digital social interaction, providing a route to early intervention.

Exercise enhances: study protocol of a randomized controlled trial on aerobic exercise as depression treatment augmentation

BACKGROUND

Major depressive disorder (MDD) is a considerable public health concern. In spite of evidence-based treatments for MDD, many patients do not improve and relapse is common. Therefore, improving treatment outcomes is much needed and adjunct exercise treatment may have great potential. Exercise was shown to be effective as monotherapy for depression and as augmentation strategy, with evidence for increasing neuroplasticity. Data on the cost-effectiveness and the long-term effects of adjunct exercise treatment are missing. Similarly, the cognitive pathways toward remission are not well understood.

METHODS

The present study is designed as a multicenter randomized superiority trial in two parallel groups with follow-up assessments up to 15 months. Currently depressed outpatients (N = 120) are randomized to guideline concordant Standard Care (gcSC) alone or gcSC with adjunct exercise treatment for 12 weeks. Randomization is stratified by gender and setting, using a four, six, and eight block design. Exercise treatment is offered in accordance with the NICE guidelines and empirical evidence, consisting of one supervised and two at-home exercise sessions per week at moderate intensity. We expect that gcSC with adjunct exercise treatment is more (cost-)effective in decreasing depressive symptoms compared to gcSC alone. Moreover, we will investigate the effect of adjunct exercise treatment on other health-related outcomes (i.e. functioning, fitness, physical activity, health-related quality of life, and motivation and energy). In addition, the mechanisms of change will be studied by exploring any change in rumination, self-esteem, and memory bias as possible mediators between exercise treatment and depression outcomes.

DISCUSSION

The present trial aims to inform the scientific and clinical community about the (cost-)effectiveness and psychosocial mechanisms of change of adjunct exercise treatment when implemented in the mental health service setting. Results of the present study may improve treatment outcomes in MDD and facilitate implementation of prescriptive exercise treatment in outpatient settings.

Physical Activity, Sleep-related Behaviors and Severity of Symptoms in Schizophrenia

The beneficial effects of a healthy sleep hygiene and regular physical activity have both been noted in improving psychopathology symptom severity. No study to date however, has evaluated the potential therapeutic effects of both sleep and exercise simultaneously in individuals diagnosed with schizophrenia. To examine the two variables concurrently, in the present report, patients with diagnoses of schizophrenia spectrum disorders (n = 64), were administered assessments that measured both their physical activity and sleep-related behaviors. Additionally, patients' symptom severity and cognitive and daily functioning abilities were also assessed. It was found sleep hygiene and physical activity were associated with patients' symptom severity and cognitive capacities, but not with their daily functioning abilities. Further, no interaction effects were found between sleep hygiene and physical activity. These results suggest that physical activity and sleep hygiene should be considered, independently, in their contribution to psychopathology.

Exercise Interventions as the Primary Treatment for Depression: Evidence from a Narrative Review

There is an increasing evidence supporting the efficacy of exercise interventions in the treatment of depression, which is a growing global health concern. However, data on the efficacy of exercise as the primary treatment for depression are scarce. This narrative review explored the efficacy of exercise interventions as the primary treatment for depressive disorders. A comprehensive search for English-language literature published between January 1965 and November 2019 was conducted via PubMed, Google Scholar, Scopus, Web of Science, PsycINFO, EMBASE, Cochrane database and Medline. Thirteen randomised control trials (RCTs) were included in the final analysis. Their results indicated that supervised aerobic exercise and high-intensity progressive resistance training (PRT) were effective in ameliorating depressive symptoms as the primary treatment compared with control groups, but they were not superior to other active treatments, such as antidepressants and cognitive behavioural therapy. Aerobic exercise and high-intensity PRT may be a promising primary treatment for depression as they may induce biopsychosocial effects (effects on neurotrophic factor, pro-inflammatory cytokines, monoamine, the hypothalamic-pituitary-adrenal axis, self-efficacy, mastery experience, adaptive coping and social interaction), which may ameliorate the severity of depressive symptoms. However, future RCTs with more comprehensive and well-designed methodologies are warranted to confirm our findings.

Effect of Acute Aerobic Exercise on Ocular Measures of Attention to Emotionally Expressive Faces

BACKGROUND

Mechanisms underlying exercise-induced mood enhancement are not well understood, but it is plausible that adaptive changes in attention to emotional stimuli underlie this effect. Thus, this study examined the effects of acute aerobic exercise on eye-tracking metrics while participants viewed emotionally expressive faces.

METHODS

Thirty-four adults (18 women) aged 21.1 ± 1.4 years completed two counterbalanced 30-min conditions: vigorous running or seated rest. Eye tracking occurred pre- and 20-min post-condition. Participants viewed positive (n = 15), negative (n = 15), and neutral (n = 15) emotional facial expressions from the NimStim repository. Fixation duration, longest fixation, number of fixations, and scan path length were analyzed using repeated measures ANOVAs.

RESULTS

Exercise improved mood, but had no effect on the dependent measures (all 3-way interactions p > 0.66). However, a main effect of emotionally expressive content for fixation duration (p = 0.04, η = 0.10) and a marginally significant effect for longest fixation (p = 0.06, ηp2 = 0.09) were detected, such that fixation duration and longest fixation were greatest for faces expressing positive emotions.

CONCLUSION

These preliminary findings indicated that acute exercise did not alter the processing of expressive faces as indexed by eye-tracking metrics of attention. However, eye tracking effectively detected processing patterns indicative of a pleasure bias while viewing emotional facial expressions.

Among Persons With Multiple Sclerosis (MS), Objective Sleep, Psychological Functioning, and Higher Physical Activity Scores Remained Stable Over 2 Years-Results From a Small Study Under Naturalistic Conditions

Background: Persons with multiple sclerosis (PwMS) are at increased risk to report poor sleep patterns and lower physical activity indices. To date, data on longitudinal objectively sleep assessment is missing. In the present study, we investigated the pattern of objective sleep and subjective physical activity indices over a period of 13.5 months, under naturalistic conditions. Method: 13.5 months after their first assessment, a total of 16 PwMS (mean age = 49.13 median EDSS score: 5; 11 females) were reassessed on their objective sleep via portable sleep-electroencephalogram (EEG-) devices, along with their subjective sleep patterns (symptoms of insomnia, restless legs syndrome (RLS), and sleep-disordered breathing), physical activity indices, psychological functioning (symptoms of depression, fatigue, daytime sleepiness), and MS-related information (fatigue, EDSS; disease-modifying treatments). While the baseline assessment was performed in a rehabilitation center, the follow-up assessment took place at participants' naturalistic and familiar setting. Results: Statistically, symptoms of depression and fatigue, subjective sleep, and physical activity levels did neither increase, nor decrease over time, although descriptively, both moderate and vigorous physical activity levels decreased, and fatigue and subjective insomnia increased. Time awake after sleep onset statistically significantly decreased, while light sleep duration increased by trend. Conclusions: Among a smaller sample of PwMS, objective sleep in their naturalistic setting remained fairly stable over a mean time lapse of 13.5 months after clinic discharge. Physical activity levels descriptively decreased. The present results are of clinical and practical importance for treatment counseling: PwMS can be reassured that their sleep quality does not deteriorate, once they have left a rehabilitation center. Further, they should be encouraged to keeping their physical activity levels as stable as possible.

[Exercise for depression treatment. Physiological mechanisms]

This literature review considers meta-analyzes, systematic reviews and original research over the last decade addressing a comprehensive analysis of the antidepressant effect of targeted physical exercise and physical activity in general. Exercise is a promising non-pharmacological treatment for depression, showing effects that are comparable or may even exceed other first-line treatments of depression. The article introduces modern ideas about the mechanisms of depression and mechanisms of exercise effects on depression manifestations. The structures of the central nervous system, changing with the effective exercise-based treatment of depression, are indicated. Physical activity stimulates the secretion of growth factors, maintenance of angio-, synapto-, and neurogenesis. The regulation of antioxidant protection of neuronal mitochondria, a decrease in pro-inflammatory reactions and stress reactivity are also observed in response to regular exercise. Physical activity has a multimodal effect that stimulates biochemical pathways and restores neuronal structures disturbed in depression.

[Exercise for depression treatment. Exercise modalities and types]

The risk of metabolic disorders, including type 2 diabetes and cardiovascular diseases, is increased in depression, there is a decrease in life expectancy by 8-10 years. Pharmacotherapy is the first-line method in the treatment of depression. However, pharmaceutical-related side-effects and resistance to antidepressant pharmacotherapy create serious problems in treatment. Regular exercise not only weakens the symptoms of depression, increases aerobic capacity and muscle strength, but also has a positive effect on comorbid diseases. The purpose of this review is to answer the question, on which parameters of exercise the antidepressant effect depends. The review highlights the results of clinical studies of different types of exercises, intensities and modalities for the treatment of depression over the past 10 years. Because of the contradictory results of the studies, it is impossible to make final conclusions regarding the parameters of exercise. It is possible to say with high probability that in the treatment of depression, moderate and intense aerobic exercises with elements of strength exercises and a variety of coordination exercises more often lead to a positive effect than monotonous exercises with low intensity. It is possible that regular patient adherence to the prescribed exercise regimen is more important than the specific exercise type.

Effects of two types of exercise training on psychological well-being, sleep, quality of life and physical fitness in patients with high-grade glioma (WHO III and IV): study protocol for a randomized controlled trial

BACKGROUND

There is existing evidence on whether and to what degree regular exercise training improves the quality of life (QoL) among cancer survivors. However, in regards to patients with high-grade glioma (HGG; WHO grade III and IV), no conclusive study has been performed so far. The present trial aims to fill this gap by examining whether psychological well-being, sleep, QoL and physical fitness might be improved with two different types of exercise, as compared to an active control condition. Active control condition represent individuals participating at regular meetings to talk about their current life situation, though, the meetings were not intended as that of the psychotherapy group. Regular meetings are of the same frequency, duration, and intensity as the exercise interventions.

METHODS

A total of 45 patients with HGG after undergoing neurosurgery and adjuvant radiotherapy, chemotherapy, or chemoradiotherapy will be consecutively and randomly assigned to (a) an endurance training, (b) a resistance training or (c) to an active control condition. The intervention will last for 6 consecutive weeks, consisting of 2 weekly sessions (30-45 min per session). Measurements would take place at three time points, namely at the beginning of the study (baseline), 3 weeks after the beginning of the study, and 6 weeks after the beginning of the study. The last measurement also represents the end of the study. Aerobic exercise performance will be assessed objectively with a 6-min walking test, and a handgrip test will be used to assess the upper body strength. Further, participants will complete a battery of questionnaires covering sociodemographic information, QoL, sleep quality and sleep patterns, coping with stress, state- and trait-anxiety, depression, and fatigue. In parallel, experts will use the Hamilton Depression Rating Scale to determine and rate participants' symptoms of depression.

SIGNIFICANCE

The present study will be the first to investigate and compare the impact of two different exercise modalities, namely endurance and resistance training, on physical fitness and dimensions of well-being, and sleep among patients with HGG who underwent neurosurgery followed by adjuvant radiotherapy, chemotherapy, or chemoradiotherapy. Importantly, unlike the majority of previous studies, the control condition consists of an active set-up to detect possible factual beneficial effects of exercise training, irrespective of social interactions.

Change in physical activity is not associated with change in mental distress among adolescents: the Tromsø study: Fit Futures

Background

Previous research shows that physical activity has a protective effect on mental distress in adults, but the relationship is less researched and seems more ambiguous for adolescents. Studies in this field have typically been cross-sectional by design and based on self-reported physical activity measures, which are known to be vulnerable to response bias. The aim of this study was to investigate the relationship between change in objectively assessed physical activity as measured by accelerometer and change in mental distress among adolescents using longitudinal data from The Tromsø Study: Fit Futures.

Method

This study was based on data from 676 upper-secondary school students (mean age 16.23 years at baseline, 45.26% boys) from The Tromsø Study: Fit Futures. Physical activity, mental distress and covariates were measured at baseline (T1) and follow-up (T2) 2 years later. Physical activity was objectively measured with an ActiGraph GT3X accelerometer over 7 days. Mental distress was measured with the Hopkins Symptom Checklist-10 (HSCL-10). Change score variables were computed as the difference between T1 and T2 in number of steps, number of minutes of moderate to vigorous physical activity (MVPA) and mental distress between T1 and T2, and analyzed using linear regression analysis.

Results

Changes in steps per day were not associated with changes in mental distress in neither the crude, partially, nor fully adjusted model. Neither was changes in minutes of MVPA per day. Interaction effects between change in both steps per day and minutes of MVPA and gender were also not statistically significant, nor was the interaction effects between baseline levels of mental distress and physical activity.

Conclusion

The results of our study indicate that for adolescents in the sample, change in physical activity is unrelated to change in mental distress over a two-year period.

Acute Exercise and Emotion Recognition in Young Adolescents

While there is evidence that acute bouts of aerobic and coordinative exercise positively affect attention and executive functions, no study has focused on the impact of acute exercise on facial-emotion processing. A total of 106 adolescents (mean age 13.0 years) were randomly assigned to a group performing either an aerobic exercise session (AER), an aerobic exercise session with coordinative demands (AER+C), or stretching. Before and after the 35-min experimental session, participants completed computerized facial-emotion labeling and emotion-matching tasks. Facial-emotion labeling, but not emotion matching, increased over time, but more so in AER and AER+C conditions. When aerobic exercise is combined with coordinative demands, greater benefits seem to be elicited for some aspects of facial-emotion recognition. Results suggest a new direction for the influence of exercising on dimensions of psychological functioning, namely on emotion processing and social cognition.

In Patients With Multiple Sclerosis, Both Objective and Subjective Sleep, Depression, Fatigue, and Paresthesia Improved After 3 Weeks of Regular Exercise

Background: Multiple sclerosis (MS) patients suffer from various difficulties including sleep complaints, symptoms of depression and fatigue, paresthesia, and cognitive impairments. There is growing evidence that regular physical activity has a positive effect on both sleep and psychological functioning, though there is limited evidence of this kind for MS patients. The aim of the present study was therefore to investigate the impact on this patient group of a regular exercise program with respect to subjective and objective sleep, depression, paresthesia, fatigue, and cognitive performance. Methods: A total of 46 patients [mean age: 50.74 years; Expanded Disability Status Scale (EDSS): mean: 5.3, 78.4% females] completed this 3-week intervention study. At baseline and 3 weeks later, they answered questionnaires covering sociodemographic information, subjective sleep, depression, fatigue, paresthesia, and subjective physical activity. Objective sleep [sleep electroencephalogram (EEG) recordings] and cognitive performance were also assessed at both time points. Patients participated in a regular exercise activity every weekday for about 60 min. Results: Compared to the baseline, by the end of the study, objective sleep had significantly improved (sleep efficiency, sleep onset latency, and wake time after sleep onset), and symptoms of sleep complaints, depression, fatigue, and paresthesia were significantly reduced. Subjective physical activity (moderate and vigorous) and cognitive performance also increased over the course of the intervention. Conclusions: In patients with MS, participation in regular exercise impacted positively on their objective and subjective sleep, depression, paresthesia, fatigue, and cognitive performance.

Influence of adjuvant omega-3-polyunsaturated fatty acids on depression, sleep, and emotion regulation among outpatients with major depressive disorders - Results from a double-blind, randomized and placebo-controlled clinical trial

BACKGROUND

Extant literature shows that adjuvant omega-3-polyunsaturated fatty acids (O3PUFAs) to a standard antidepressant medication impacts favorably on symptoms of depression in participants with major depressive disorders (MDD). The aim of the present study was to investigate, if and to what extent compared to placebo adjuvant O3PUFAs had a favorable impact on symptoms of depression, anxiety, sleep and emotion regulation among outpatients with MDD.

METHOD

A total of 50 outpatients (mean age: M = 42.46; 68% females) took part in this randomized, double-blind and placebo-controlled study. They were randomly assigned either to the O3PUFA- or to the placebo-condition. Standard medication was sertraline at therapeutic dosages. At baseline, six weeks and 12 weeks later at study completion participants completed questionnaires covering symptoms of depression, anxiety sensitivity, intolerance of uncertainty, sleep disturbances, and emotion regulation. In parallel, experts blind to participants' group assignment rated participants' depression with the Montgomery-Asberg Depression Scale.

RESULTS

Symptoms of depression (self- and experts' ratings) decreased over time, but more so in the O3PUFA condition, compared to the placebo condition. Likewise, anxiety sensitivity, intolerance of uncertainty and sleep disturbances improved, but again more so in the O3PUFA condition. Further, regulation and control of emotions and perception of other's emotions improved over time, but more so in the O3PUFA condition.

CONCLUSIONS

Among outpatients with MDD, and compared to placebo, adjuvant O3PUFAs to a standard medication improved not only symptoms of depression, but also dimensions of anxiety and sleep, and above all patients' competencies to regulate their emotions.

Psychiatric In-Patients Are More Likely to Meet Recommended Levels of Health-Enhancing Physical Activity If They Engage in Exercise and Sport Therapy Programs

Background: People with mental disorders engage in sedentary behaviors more often than their healthy counterparts. In Switzerland, nearly all psychiatric hospitals offer structured exercise and sport therapy as part of their standard therapeutic treatment. However, little is known about the degree to which psychiatric patients make use of these treatment offers. The aim of this study is to examine, in a sample of psychiatric in-patients (a) how many participate in the structured exercise and sport therapy programs offered by the clinic, (b) how many engage in exercise and sport activities on an individual basis, and (c) how many meet recommended levels of health-enhancing physical activity during their stay at the clinic. Furthermore, we examine whether those who engage in exercise and sport activities are more likely to meet internationally accepted physical activity recommendations. Methods: 107 psychiatric in-patients (49% women, M_age = 39.9 years) were recruited at three psychiatric clinics in the German-speaking part of Switzerland. All participants were engaged in treatment and received usual care. Based on accelerometer data, participants were classified as either meeting or not meeting physical activity recommendations (≥150 min of moderate-to-vigorous physical activity per week). Participation in structured and individually performed exercise and sport activities was assessed with the Simple Physical Activity Questionnaire. Results: In total, 57% of all patients met physical activity recommendations. 55% participated in structured exercise and sport therapy activities, whereas only 22% of all patients engaged in exercise and sport activities independently. Psychiatric patients were significantly more likely to meet recommended levels of health-enhancing physical activity if they engaged in at least 60 min per week of structured exercise and sport therapy or in at least 30 min of individually performed exercise and sport activity. Conclusions: Given that prolonged immobilization and sedentary behavior have harmful effects on patients' physical and mental well-being, promoting exercise and sport activities is an important endeavor in psychiatric care. Clinics currently succeed in involving between 50 and 60% of all patients in sufficient physical activity. While this is encouraging, more systematic efforts are needed to ensure that all patients get enough physical activity.
