Acceptance and Commitment Therapy (ACT) Improves Sleep Quality, Experiential Avoidance, and Emotion Regulation in Individuals with Insomnia-Results from a Randomized Interventional Study

A Multiple Mediator Model of Depression, Dysfunctional Beliefs about Sleep, and Sleep Effort in the Relationship between Psychological Inflexibility and Insomnia in Shift Working Nurses

The aims of this study were to explore the influence of shift working nursing professionals' psychological inflexibility on their level of insomnia. Additionally, we investigated the mediation effect of depression and sleep-related cognitions on this association. An online survey was conducted among 202 nursing professionals at Asan Medical Center from July to August, 2023. Participants responded to questionnaires including the Insomnia Severity Index (ISI), Acceptance and Action Questionnaire-II (AAQ-II), Dysfunctional Beliefs and Attitudes about Sleep - 16 (DBAS-16), Glasgow Sleep Effort Scale (GSES), Patient Health Questionnaire-9 items (PHQ-9), and the Discrepancy between desired time in bed and desired total sleep time index (DBST index). Pearson's correlation and linear regression were performed to explore the factors predicting ISI scores. Mediation analysis was implemented. Linear regression revealed that insomnia severity was predicted by DBAS-16 (β = 0.15, p = 0.008), GSES (β = 0.48, p < 0.001), and PHQ-9 (β = 0.26, p < 0.001). Mediation analysis showed that the relationship between the psychological inflexibility of shift-working nursing professionals' and insomnia severity was fully mediated by depression, dysfunctional beliefs about sleep, and sleep effort. Psychological inflexibility does not directly influence insomnia severity, but depression, dysfunctional beliefs about sleep, and sleep effort fully mediate the relationship.

Preoccupation with sleep and dysfunctional beliefs about sleep mediate the influence of psychological inflexibility on insomnia in the older adult population

INTRODUCTION

This study aimed to explore whether the Discrepancy between the desired time in Bed and the desired total Sleep Time (DBST) index influences insomnia severity in the older adult population and examined the potential role of psychological inflexibility in this association.

METHODS

An online survey study was conducted for older individuals aged ≥ 65 via a survey company between January and February 2023. A total of 300 responses and data without personally identifiable information were delivered to the researchers. The survey questionnaires include the DBST, Glasgow Sleep Effort Scale (GSES), Insomnia Severity Index (ISI), Dysfunctional Beliefs about Sleep-2 items (DBS-2), and Acceptance and Action Questionnaire-II (AAQ-II).

RESULTS

The analysis included 295 older adult participants. The DBST index was significantly correlated with all questionnaires. Linear regression revealed the DBST index was predicted only by the ISI (β = 0.26, p = 0.003). Mediation analysis showed that the GSES (Z = 2.92, p = 0.003) and DBS-2 (Z = 2.17, p = 0.030) mediated the effect of the DBST index on the ISI, while the AAQ-II did not. Path analysis showed that the DBST could be directly predicted by the ISI (Z = 2.94, p = 0.003), GSES (Z = 2.75, p = 0.006), and DBS2 (Z = 2.71, p = 0.007) but not by the AAQ-II itself. However, the AAQ-II exerted a significant indirect effect on the ISI through the DBS-2 (Z = 2.21, p = 0.027) and GSES (z = 2.24, p = 0.025).

CONCLUSIONS

Our study showed that preoccupation and dysfunctional beliefs about sleep may mediate the relationship between the DBST index and insomnia severity in the older adult population. We opine that psychological inflexibility might play a significant role in insomnia severity via preoccupation with and dysfunctional beliefs about sleep.

Assessing shared psychological constructs as risk factors in comorbid PTSD-AUD combat-exposed male veterans

PTSD and AUD are frequently comorbid post-trauma outcomes. Much remains unknown about shared risk factors as PTSD and AUD work tends to be conducted in isolation. We examined how self-report measures of distress tolerance (DT), experiential avoidance (EA), and drinking motives (DM) differed across diagnostic groups in white, male combat-exposed veterans (n = 77). A MANOVA indicated a significant difference in constructs by group, F (5, 210) = 4.7, p = <.001. Follow-up ANOVAs indicated DM subscales (Coping: F (3,82) = 21.3; Social: F (3,82) = 13.1; Enhancement: F (3,82) = 10.4; ps = <.001) and EA (F (3,73) = 7.8, p < .001) differed by groups but not DT. Post hoc comparisons indicated that mean scores of the comorbid and AUD-only groups were significantly higher than controls for all DM subscales (all ps < .01). EA scores were significantly higher for the comorbid as compared to control (p < .001) and PTS-only (p = .007) groups. Findings support shared psychological factors in a comorbid PTSD-AUD population.

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.

Experiential Avoidance Process Model: A Review of the Mechanism for the Generation and Maintenance of Avoidance Behavior

Experiential avoidance refers to a phenomenon in which individuals exhibit an unwillingness to engage with certain personal experiences, including physical sensations, emotions, thoughts, memories, and behavioral tendencies. They employ cognition and emotions to avoid these experiences. Extensive research has linked experiential avoidance to various mental diseases, conduct disorder, and posttraumatic stress disorder. While the existing literature highlights the significance of understanding experiential avoidance as a central mechanism underlying psychological symptomatology development and maintenance, further investigation is required to comprehend its dimensions and mechanisms fully. Therefore, this article aims to provide a comprehensive review of the current theories and empirical evidence on experiential avoidance while elucidating its association with psychopathology. We propose a model of experiential avoidance processes based on an extensive review and critical analysis of the previous emotion regulation model that integrates expressive suppression and cognitive reappraisal during emotion regulation through experiential avoidance. This proposed model seeks to explain both the formation and maintenance aspects of experiential avoidance by offering valuable insights for future research. We also examined the association between experiential avoidance and various psychiatric disorders, including anxiety, depression, obsessive-compulsive disorder, and posttraumatic stress disorder. Elaborating on these mechanisms provides a roadmap for future research endeavors and clinical interventions.

Sleep health and associated factors among undergraduates during the COVID-19 in China: A two-wave network analysis

Using network analysis, the current study investigated the pathways that underlie selected components of sleep health and their changes over time. Undergraduates (N = 1423; 80.60% female) completed a two-wave survey, sleep health (i.e. chronotypologies (CTs), sleep procrastination (SP), sleep quality (SQ)), psychological distress (PD), emotion regulation (ER), self-control (SC), problematic smartphone use (PSU) were measured. CTs, SP, and SQ formed a spatially contiguous pattern that remained unchanged in both waves. ER and PD node increased its strength, betweenness, and closeness in the network, while the link between the two was strengthened at T2. PSU was connected to SP, but not to CTs and SQ during both waves. In the context of the network approach, SP had the highest strength, and its associations with other dimensions of individual sleep may represent key factors in understanding the influence of exposure to the COVID-19 outbreak on sleep health.

Associations between Sleep Disturbances, Personality Traits and Self-Regulation in a Sample of Healthy Adults

Background: Scientific evidence and everyday experience show that sleep disturbances and self-regulation as a proxy of stress reactivity are linked. Particular personality traits such as neuroticism, internalizing and externalizing problems are also associated with sleep disturbances. Here, we combined self-regulation and personality traits and associated these variables with subjective sleep disturbances. Methods: A total of 846 adults (mean age: 33.7 years; 78.7% females) completed questionnaires covering sleep disturbances, self-regulation and personality traits. Results: Higher scores for sleep disturbances were associated with higher scores for externalization, internalization, and instability and with lower scores for stability (all trait variables) and with poorer self-regulation (state variable). The regression model showed that higher scores for externalization and internalization (traits), and lower scores for self-regulation (state) predicted higher scores for sleep disturbance. Next, self-regulation had both a direct effect on sleep disturbance, and an indirect effect via personality traits. Conclusions: Sleep disturbances were related to both state (i.e., self-regulation) and trait (e.g., internalization and instability) dimensions. The current data analysis leapfrogs the state-trait dichotomy discussion and reconciles the state-and-trait approach in the prediction of poor sleep, though self-regulation appeared to have both direct and indirect effects on sleep disturbances.

Are "night owls" or "morning larks" more likely to delay sleep due to problematic smartphone use? a cross-lagged study among undergraduates

Sleep is an important physiological process, but staying up late has become a worldwide problem, particularly among university students. Sleep procrastination has been found to associated with sleep biorhythms and problematic smartphone use ("PSU") in previous studies. This two-wave study examines the longitudinal reciprocal relationship between PSU and sleep procrastination, together with the moderating role of sleep biorhythms. Participants comprised 1,423 Chinese university students. The results revealed that PSU and sleep procrastination are reciprocally related. Additionally, sleep biorhythms moderated this relationship, as PSU at T1 significantly predicted sleep procrastination at T2 for the morning larks group but not the night owls group. Accordingly, both PSU and sleep biorhythms should be considered when developing interventions for sleep procrastination.

Acceptance and Commitment Therapy, Combined with Bedtime Restriction, versus Cognitive Behavioral Therapy for Insomnia: A Randomized Controlled Pilot Trial

INTRODUCTION

Cognitive behavioral therapy for insomnia (CBT-I) is the current first-line treatment for insomnia. However, rates of nonresponse and nonremission are high and effects on quality of life are only small to moderate, indicating a need for novel treatment developments. We propose that Acceptance and Commitment Therapy (ACT) addresses core pathophysiological pathways of insomnia. ACT therefore has the potential to improve treatment efficacy when combined with bedtime restriction, the most effective component of CBT-I. The aim of this study was to compare the efficacy of ACT for insomnia combined with bedtime restriction (ACT-I) and CBT-I in improving insomnia severity and sleep-related quality of life.

METHODS

Sixty-three patients with insomnia disorder (mean age 52 years, 65% female, 35% male) were randomly assigned to receive either ACT-I or CBT-I in a group format. The primary outcomes were insomnia severity (Insomnia Severity Index) and sleep-related quality of life (Glasgow Sleep Impact Index). Outcomes were assessed before randomization (T0), directly after treatment (T1), and at 6-month follow-up (T2).

RESULTS

The results indicated significant, large pre-to-post improvements in both groups, for both primary and secondary outcomes. Improvements were maintained at the 6-month follow-up. However, there was no significant group by time interactions in linear mixed models, indicating an absence of differential efficacy. On a subjective treatment satisfaction scale, patients in the ACT-I group indicated significantly greater satisfaction with their improvement of several aspects of health including their energy level and work productivity.

CONCLUSIONS

The results suggest that ACT-I is feasible and effective, but not more effective than CBT-I for the improvement of insomnia severity and sleep-related quality of life. Future studies are needed to assess whether ACT-I is noninferior to CBT-I and to shed light on mechanisms of change in both treatments.

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.

A Study of Emotion Regulation Difficulties, Repetitive Negative Thinking, and Experiential Avoidance in Adults with Stuttering: A Comparative Study

Objective: Stuttering is a type of communication and fluency disorder that hurts mental and emotional health. It is also associated with a significant increase in both trait and social anxiety. Studies on stuttering in adults have indicated the nature and impact of this phenomenon. In addition, some psychological aspects of this phenomenon remain vague and need further investigation. Therefore, the present study aimed to compare emotion regulation difficulties, repetitive negative thinking, and experiential avoidance between people who stutter and healthy individuals. Method : In this study, 101 people who stutter (43 females and 58 males, with a mean age of 29.55 ± 187 years), as well as 110 healthy individuals (74 females and 36 males, with a mean age of 25.57 ± 489 years) as participants were chosen using the convenience sampling method among those who referred to the speech therapy clinics of Tehran, Iran. Research instruments including the repetitive negative thinking inventory, Difficulties in Emotion Regulation Scale, and Acceptance and Action Questionnaire (AAQ-I) were used for data collection. Data were analyzed using multivariate ANOVA test and Multiple Regression Analysis. Results: The mean age of the participants was 29.55 years in the people who stutter and 25.57 years in the healthy individuals (P < 0.01). The present results indicated that the mean score of experiential avoidance was higher in the people who stutter (M ± SD: 35.74 ± 9.24) compared to the healthy individuals (M ± SD: 8.89 ± 31.11). Additionally, the mean score of emotion regulation difficulties was higher in the people who stutter (M ± SD: 88.75 ± 20.59) compared to the healthy individuals (M ± SD: 64.14 ± 94.94) (P < 0.001). However, there was no significant difference in the mean score of repetitive negative thinking between the people who stutter (M ± SD: 98.45 ± 25.85) and healthy individuals (M ± SD: 93.71 ± 25.24) groups (P > 0.05). There was a significant correlation between experiential avoidance and emotion regulation difficulties in people who stutter (P < 0.01). Experiential avoidance and repetitive negative thinking can significantly predict emotion regulation difficulties in people who stutter (R = 0.65, P < 0.01). Conclusion: People who stutter obtained higher emotion regulation difficulties and experiential avoidance scores than those without stuttering and A significant correlation between experiential avoidance and emotion regulation difficulties was found. Future studies should consider the role of emotion regulation difficulties and experiential avoidance in people who stutter.

The European Insomnia Guideline: An update on the diagnosis and treatment of insomnia 2023

Progress in the field of insomnia since 2017 necessitated this update of the European Insomnia Guideline. Recommendations for the diagnostic procedure for insomnia and its comorbidities are: clinical interview (encompassing sleep and medical history); the use of sleep questionnaires and diaries (and physical examination and additional measures where indicated) (A). Actigraphy is not recommended for the routine evaluation of insomnia (C), but may be useful for differential-diagnostic purposes (A). Polysomnography should be used to evaluate other sleep disorders if suspected (i.e. periodic limb movement disorder, sleep-related breathing disorders, etc.), treatment-resistant insomnia (A) and for other indications (B). Cognitive-behavioural therapy for insomnia is recommended as the first-line treatment for chronic insomnia in adults of any age (including patients with comorbidities), either applied in-person or digitally (A). When cognitive-behavioural therapy for insomnia is not sufficiently effective, a pharmacological intervention can be offered (A). Benzodiazepines (A), benzodiazepine receptor agonists (A), daridorexant (A) and low-dose sedating antidepressants (B) can be used for the short-term treatment of insomnia (≤ 4 weeks). Longer-term treatment with these substances may be initiated in some cases, considering advantages and disadvantages (B). Orexin receptor antagonists can be used for periods of up to 3 months or longer in some cases (A). Prolonged-release melatonin can be used for up to 3 months in patients ≥ 55 years (B). Antihistaminergic drugs, antipsychotics, fast-release melatonin, ramelteon and phytotherapeutics are not recommended for insomnia treatment (A). Light therapy and exercise interventions may be useful as adjunct therapies to cognitive-behavioural therapy for insomnia (B).

Novel treatment based on acceptance and commitment therapy versus cognitive behavioral therapy for insomnia: A randomized comparative effectiveness trial in women veterans

OBJECTIVE

This randomized comparative effectiveness trial evaluated a novel insomnia treatment using acceptance and commitment therapy (ACT) among women veterans. Participants received either the acceptance and the behavioral changes to treat insomnia (ABC-I) or cognitive behavioral therapy for insomnia (CBT-I). The primary objectives were to determine whether ABC-I was noninferior to CBT-I in improving sleep and to test whether ABC-I resulted in higher treatment completion and adherence versus CBT-I.

METHOD

One hundred forty-nine women veterans with insomnia disorder (Mage = 48.0 years) received ABC-I or CBT-I. The main sleep outcomes were Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and sleep efficiency (SE) by actigraphy (objective) and sleep diary (subjective). Measures were collected at baseline, immediate posttreatment, and 3-month posttreatment follow-up. Treatment completion and adherence were assessed during the interventions.

RESULTS

Both interventions improved all sleep outcomes from baseline to immediate posttreatment and 3-month posttreatment follow-up. At immediate posttreatment, ABC-I was statically noninferior for sleep diary SE and objective SE, but noninferiority was not statistically confirmed for ISI or PSQI total scores. At 3-month posttreatment follow-up, ABC-I was noninferior for all four of the key outcome variables. There was not a statistically significant difference between the number of participants who discontinued CBT-I (11%) versus ABC-I (18%; p = .248) before completing treatment. ABC-I was superior to CBT-I for some adherence metrics.

CONCLUSIONS

Overall, ABC-I was similar in effectiveness compared to CBT-I for the treatment of insomnia and may improve adherence to some behavioral elements of treatment. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Validation of the Farsi Version of the Adult Concentration Inventory for Assessing Cognitive Disengagement Syndrome

The internal and external validity of cognitive disengagement syndrome (CDS) relative to attention-deficit/hyperactivity disorder-inattention (ADHD-IN) was evaluated herein with Farsi-speaking adults. A total of 837 Iranian adults assessed throughout the whole country (54.72% women, Mage = 23.85; SD = 7.05; age range = 18 to 58 years; 75% between 18 and 24 years old; reporting higher educational training) completed self-report measures of CDS, ADHD-IN, ADHD-hyperactivity/impulsivity (HI), depression, anxiety, and stress. Seven of the fifteen CDS symptoms showed a good convergent (high loadings on the CDS factor) and discriminant (higher loadings on the CDS factor than the ADHD-IN factor) validity. CDS also showed stronger first-order and unique associations with depression than ADHD-IN, whereas ADHD-IN showed stronger first-order and unique associations with ADHD-HI and anxiety than CDS. The first-order and unique associations of CDS and ADHD-IN did not differ in relation to stress. This study is the first to support the validity of the self-report of assessing CDS symptoms with the Adult Concentration Inventory with Farsi-speaking individuals residing in Iran, thus further strengthening the transcultural validity of the CDS, and paving the way for further transcultural research in the field of CDS among adults.

Comparison of Acceptance and Commitment Therapy (ACT) and Cognitive Behavior Therapy (CBT) for Chronic Insomnia: A Pilot Randomized Controlled Trial

Purpose

Acceptance and Commitment Therapy (ACT) is part of the third wave of cognitive behavior therapy, and has six core components: acceptance, cognitive defusion, self as context, being present, values, and committed behavior. This study aimed to examine the efficacy of ACT for insomnia compared with cognitive behavior therapy for insomnia (CBT-I) in patients with chronic primary insomnia.

Methods

The study recruited patients with chronic primary insomnia from a university hospital between August 2020 and July 2021. Thirty patients were enrolled and randomly assigned to receive either ACT (n = 15) or CBT-I (n = 15). Interventions were performed over four weeks, with four sessions of face-to-face therapy and four sessions of online therapy. The outcomes were measured using a sleep diary and a questionnaire.

Results

Post-intervention, the ACT and CBT-I groups had significantly improved sleep quality, insomnia severity, depression, beliefs about sleep, sleep onset latency (SOL), and sleep efficacy (SE) (p < 0.05). However, anxiety was significantly reduced in the ACT group (p = 0.015), but not in the CBT-I group.

Conclusion

ACT had a significant effect on primary insomnia and secondary symptoms, especially anxiety related to insomnia. These findings suggest that ACT could be a potential intervention for individuals who do not respond to CBT-I, who have high anxiety regarding sleep problems.

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.

Depression mediates the relationship of experiential avoidance and internet addiction: a cross-lagged mediation analysis

Previous research has identified the contemporaneous association between experiential avoidance, depression, and Internet addiction. However, the mechanisms underlying this association are not well acknowledged. The present study aimed to use cross-lagged panel modeling to examine whether depression mediates the relation between experiential avoidance and Internet addiction and whether gender plays a role in the relation. A total of 2731 participants (934 male, Meanage=18.03) were recruited from a university at the baseline study (December 2019). Data was collected at all 3 time points across one year (2019?2020), using 6-month intervals. Experiential avoidance, depression and Internet addiction were assessed using the Acceptance and Action Questionnaire-II (AAQ-II), the Beck Depression Inventory-II (BDI-II) questionnaire, and Young?s Internet Addiction Test (IAT), respectively. Cross-lagged panel models were used to evaluate the longitudinal association and the mediating effect. Multigroup analyses were conducted to examine gender differences in the models.Cross-lagged models indicated that experiential avoidance significantly predicted subsequent depression, and depression significantly predicted subsequent Internet addiction. Furthermore, mediation analyses showed that depression has a mediating effect in the relation between experiential avoidance and Internet addiction (? = 0.010, 95%CI[0.003, 0.018], p>0.001). Multigroup analyses demonstrated that the pattern of structural relations stayed consistent across gender. The findings indicated that experiential avoidance is indirectly related to Internet addiction through depression, suggesting that treatments targeted at reducing experiential avoidance could help relieve depression and thus decrease the risk of Internet addiction.

Acceptance and Commitment Therapy as an Adjunct or Alternative Treatment to Cognitive Behavioral Therapy for Insomnia

Although cognitive behavioral therapy for insomnia (CBT-I) is an effective treatment of insomnia, difficulties exist with adherence to recommendations and premature discontinuation of treatment does occur. The current article aims to review existing research on acceptance and commitment therapy (ACT)-based interventions, demonstrate differences and similarities between ACT for insomnia and CBT-I, and describe treatment components and mechanisms of ACT that can be used to treat insomnia disorder.

The contribution of transdiagnostic vulnerability factors in patients with chronic insomnia

Introduction

Various transdiagnostic factors have been associated with insomnia severity. The current study aimed to predict insomnia severity based on a group of transdiagnostic factors including neuroticism, emotion regulation, perfectionism, psychological inflexibility, anxiety sensitivity, and repetitive negative thinking after controlling for depression/anxiety symptoms and demographic characteristics.

Methods

Two hundred patients with chronic insomnia disorder were recruited from a sleep disorder clinic. Participants completed the Insomnia Severity Index (ISI), Clinical Perfectionism Questionnaire (CPQ), Acceptance and Action Questionnaire-II (AAQ-II), Anxiety Sensitivity Index-3 (ASI-3), Repetitive Thinking Questionnaire (RTQ-10), Big Five Inventory (BFI-10), Emotion Regulation Questionnaire (ERQ), and Depression Anxiety Stress Scale (DASS-21).

Results

After controlling for the confounding variables (depression/anxiety symptoms and demographic characteristics), hierarchical multiple linear regression suggested the significant association of neuroticism (BFI), cognitive reappraisal (ERQ), personal standards (CPQ), evaluative concerns (CPQ), physical concerns (ASI), cognitive concerns (ASI), and repetitive negative thinking (RTQ) with insomnia severity.

Discussion

The findings support the role of transdiagnostic factors, especially physical concerns, repetitive negative thinking, and neuroticism in chronic insomnia. Future research using longitudinal designs is required to verify the causal status of transdiagnostic variables.

Cognitive and psychological factors associated with severe insomnia in Brazilian women: a cross-sectional study

Insomnia is the most prevalent sleep disorder in women. Sociodemographic, cognitive, and psychological factors may contribute to its severity. This study evaluated factors associated with severe insomnia in women with insomnia complaints. We evaluated 530 women aged 18-59 (mean = 40.5, SD = 10.2), who experienced insomnia complaints, using self-report instruments. Severe insomnia was defined as a score above 21 on the Insomnia Severity Index. Age, marital status, educational level, depression and anxiety, psychological inflexibility, and beliefs about sleep were assessed as potential factors associated with severe insomnia. Simple and multivariate analyses were conducted using binary logistic regression. Low education level (odds ratio; OR = 1.85 [1.27-2.69]), depression (OR = 2.17 [1.27-3.81]), psychological inflexibility (OR = 1.05 [1.02-1.08]), and dysfunctional beliefs about sleep (OR = 1.04 [1.02-1.06]) were factors associated with severe insomnia scores in the multiple logistic regression model. These findings are important from a public health perspective, because behavioral strategies designed to treat insomnia with a focus on cognitive and psychological factors are low-cost treatments and may help improve sleep quality in women, which also influences mental health.

Trait Acceptance Buffers Aggressive Tendency by the Regulation of Anger during Social Exclusion

Social exclusion has led to increased negative emotions and aggressive behaviors, two outcomes that are correlated with each other. Thus, the down-regulation of negative emotions appears to play a crucial role in reducing the tendency for aggressive behavior. However, this assumption has not yet been tested. To this end, a total of 397 undergraduates reported their aggressive tendencies, state emotions and trait acceptance by completing corresponding questionnaires, and a recall paradigm was used to induce experiences of social exclusion. The results showed that in the context of social exclusion, (1) trait acceptance was negatively correlated with negative emotions and aggressive tendency but was positively correlated with positive emotions; (2) negative emotions, rather than positive emotions, were positively correlated with aggressive tendency; (3) increased trait acceptance buffered the experience of anger, which is, in turn, related to reduced aggressive tendency; (4) trait acceptance also downregulated the feeling of sadness, which is, however, related to increased aggression; (5) the mediator of sadness was smaller in effect size than that of anger. Taken together, these results suggest that negative emotions are associated with aggression in the context of social exclusion, and the habitual use of an acceptance strategy was conductive to decreasing aggressive tendencies by decreasing anger.

Effects of two types of exercise training on psychological well-being, sleep and physical fitness in patients with high-grade glioma (WHO III and IV)

BACKGROUND

There is evidence that regular exercise training has the potential to improve psychological well-being among cancer survivors. However, limited findings are available for individuals with high-grade glioma (HGG; WHO grade III and IV) after neurosurgery and undergoing radiochemotherapy. Given this, endurance and strengths training were employed to investigate their impact on symptoms of depression, feelings of stress and anxiety, fatigue, insomnia, and physical fitness, compared to an active control condition.

METHODS

A total of 29 patients (M = 52.07, SD = 12.45, 55.2% women) participated in this randomized controlled trial (RCT). After neurosurgical treatment and during adjuvant radiotherapy and chemotherapy or combined radiochemotherapy, patients were randomly assigned to the following conditions: Endurance training (n = 10); strengths training (n = 11); active control condition (n = 8). At baseline, three weeks and six weeks later at the end of the study physical fitness was objectively measured with a 6-min walk test (6MWT) and a handgrip test. Participants completed a series of questionnaires covering sociodemographic information, symptoms of depression, stress, anxiety, fatigue, and insomnia. Further, experts rated participants' severity of symptoms of depression.

RESULTS

Over time and compared to the strengths and active control condition, self-rated symptoms of depression, state and trait anxiety, stress and insomnia decreased in the endurance condition. Over time and compared to the endurance and active control condition, no changes on symptoms of depression, anxiety, stress, or insomnia were observed in the strengths condition. Over time and compared to the endurance and strengths condition, symptoms of depression (self-ratings), stress, insomnia and fatigue decreased in the active control condition. Fatigue increased in both exercising conditions. Over time and irrespective from the study condition, physical fitness did neither improve nor decrease.

CONCLUSIONS

The pattern of results suggests that endurance training and an active control condition improved dimensions of depression, stress, and anxiety, while mere strengths training appeared to neither improve, nor decrease dimensions of psychological functioning. Further, exercise interventions did not change physical fitness, but increased fatigue. Overall, endurance training and an active control condition appeared to favorably impact on psychological well-being among patients with high-grade glioma after neurosurgery and undergoing radiochemotherapy.

Effect of acceptance and commitment therapy on mood, sleep quality and quality of life in menopausal women: a randomized controlled trial

BACKGROUND

One of the most critical periods in a woman's life is menopause. During menopause, depression and anxiety are among the most common mood changes. Sleep disorders also increase during menopause, which leads to quality of life disorders. Different methods such as medication, psychotherapy, or a combination of them are used to treat these disorders. Acceptance and commitment-based therapy is one of the newest methods in psychotherapy that recently has been used a lot. Therefore, this study was conducted to determine the effect of acceptance and commitment therapy (ACT) on mood (primary outcome), sleep quality, and quality of life (secondary outcomes) of menopausal women.

METHODS

This randomized controlled trial was performed on 86 menopausal women in Tabriz, Iran in 2021. Using the blocking method, participants were randomly assigned into the intervention and control groups. The intervention group received counseling based on ACT approach in 8 sessions of 60 to 90 min. The control group received only routine health care. Depression, Anxiety, Stress Scale-21 (DASS 21), Menopause Quality of Life (MENQOL), and Pittsburgh Sleep Quality Index (PSQI) questionnaires were completed before intervention and immediately after the intervention. Independent t-test and Mann-Whitney U test were used to compare the outcomes between the two groups.

RESULTS

In terms of sociodemographic characteristics and baseline values of the studied variables, there was no statistically significant difference between the study groups before the intervention. At the end of the intervention, the mean (SD: standard deviation) scores of anxiety, stress, and depression in the counseling group were 2.66 (1.28), 2.91 (1.62), and 1.98 (1.59) and in the control group were 4.19 (1.85), 5.61 (1.49) and 3.59 (1.91). In the intervention group, the mean score of all three variables was significantly lower than the control group (P < 0.001). After the intervention, the mean (SD) of the total sleep quality score was 4.04 (2.52) in the counseling group and 4.13 (2.63) in the control group. In addition, the mean (SD) of the total quality of life score was 23.47 (20.13) in the counseling group and 23.14 (17.76) in the control group. Between the study groups, there were no statistically significant differences in the mean of the overall score of sleep quality (P = 0.867) and the overall score of quality of life (P = 0.759).

CONCLUSION

Using ACT-based counseling can improve the mood of menopausal women. However, further randomized clinical trials are needed before making a definitive conclusions.

Influence of adjuvant clonidine on mania, sleep disturbances and cognitive performance - Results from a double-blind and placebo-controlled randomized study in individuals with bipolar I disorder during their manic phase

BACKGROUND

While the favorable effect of adjuvant clonidine in the treatment of acute mania has been observed already about 40 years ago, this line of treatment has not been further investigated. Here, we resumed this topic, and we tested the effect of adjuvant clonidine, an antihypertensive stimulating the alpha-₂ central adrenergic receptor, on symptoms of mania, cognitive performance, and subjective sleep. To this end, we performed a randomized, double-blind and placebo-controlled clinical trial among inpatients with bipolar disorder I during their acute phase of mania.

METHODS

A total of 70 inpatients (mean age: 37.40 years; 15.7% females) with diagnosed bipolar disorder I and during their acute manic phase were randomly assigned either to the adjuvant clonidine (0.2 mg/d to a maximum of 0.6 mg/d) or to the placebo condition. Standard medication was lithium at therapeutic dosages. At baseline, participants completed a series of self-rating questionnaires covering sociodemographic information and subjective sleep. Subjective sleep was re-assessed 24 days later at the end of the study. Experts rated participants' acute state of mania with the Young Mania Rating Scale at baseline and at day 12 and day 24. Participants' cognitive performance was assessed at baseline and at day 24 at the end of the study.

RESULTS

Over time, mania scores significantly decreased (large effect size), but more so in the clonidine condition, compared to the placebo condition (medium effect size). Likewise, over time, subjective sleep improved (large effect size), but more so in the clonidine, compared to the placebo condition (medium effect size). Over time, cognitive performance improved (medium effect size), irrespective from the study condition.

CONCLUSIONS

Compared to placebo, adjuvant clonidine to lithium improved symptoms of mania, as rated by experts', and subjective sleep quality. Adjuvant clonidine had no further favorable (or detrimental) impact on cognitive performance.

When Non-Suicidal Self-Injury Predicts Non-Suicidal Self-Injury and Poor Sleep-Results from a Larger Cross-Sectional and Quasi-Longitudinal Study

Poor sleep is associated with a higher risk of non-suicidal self-injury (NSSI) as a proxy of unfavorable emotion regulation. In the present study, we tested the hypothesis that past non-suicidal self-injury was associated with current non-suicidal self-injury and with current subjective sleep patterns. To this end, a larger sample of young adults were assessed. A total of 2374 adults (mean age: 27.58 years; 39.6% females) completed a series of self-rating questionnaires covering sociodemographic information, past and current NSSIs, suicide attempts, and current sleep patterns, including experiencing nightmares. Past NSSIs predicted current NSSIs. Current sleep patterns had a modest impact on the association between past and current NSSIs. Compared to male participants, female participants did not report more sleep complaints or more current NSSIs, but more past NSSIs. Past NSSIs predicted the occurrences of nightmares and suicide attempts. The best predictor of current NSSI was the remembered past NSSI, while current poor sleep was only modestly associated with current NSSI. Further indicators of current NSSI and poor sleep were suicide attempts and nightmares within the last six months. Overall, it appears that poor emotion regulation should be considered as underlying factor to trigger and maintain non-suicidal self-injury-related behavior and poor sleep. Further, unlike previous studies, which focused on the possible influence of sleep patterns on NSSIs, the aim of the present study paradigm was to investigate NSSIs on sleep patterns.

Effectiveness of a Mindfulness and Self-Compassion Standard Training Program versus an Abbreviated Training Program on Stress in Tutors and Resident Intern Specialists of Family and Community Medicine and Nursing in Spain

Stress is one of the most common problems among healthcare professionals, as they are exposed to potentially stressful and emotionally challenging situations in the workplace. Mindfulness-based stress reduction (MBSR) training programs have been shown to decrease stress. The objective of this study was to compare the effectiveness of an abbreviated 4-weeks MBSR training program in relation to a standard 8-weeks one on the stress levels. A controlled and randomized clinical trial was designed, in which 112 tutors and resident intern specialists in Family and Community Medicine and Nursing of six Spanish National Health System teaching units (TUs) participated. Participants included in the experimental groups (EGs) received a MBRS training program (standard or abbreviated), while control group (CG) participants did not receive any intervention. The stress levels were assessed by the Perceived Stress Questionnaire (PSQ) in three different moments during the study: before, immediately after, and 3 months after the intervention. Adjusted covariance analysis (ANCOVA), using pretest scores as the covariate, showed a significant reduction in stress (F_(2,91) = 5.165; p = 0.008; η² = 0.102) in the post-test visit, attributable to the implementation of the standard training program, but without the maintenance of its effects over time. No significant impact of the abbreviated training program on stress levels was observed in the intergroup comparison. A standard 8-weeks MBSR training program aimed at tutors and resident intern specialists in Family and Community Medicine and Nursing produces significant improvements in stress levels compared with the abbreviated intervention and no intervention. New studies about abbreviated training programs are needed to provide effective treatments which improve well-being of these professionals.

Daily physical activity, human development index and insomnia in a representative sample of Brazilian adolescents: a cross-sectional analysis

BACKGROUND

Although there is a growing body of research pointing towards the need to investigate how different movement behaviors, such as physical activity and sleep, influence each other, the joint relationship between these factors and insomnia has been little explored among adolescents in developing countries.

OBJECTIVES

To investigate the association between daily physical activity and insomnia in a national sample of Brazilian adolescents, according to the Human Development Index (HDI) of each Brazilian region.

DESIGN AND SETTINGS

Cross-sectional study on 102,072 Brazilian students aged 11 to 19 years, selected from all regions of the country.

METHODS

Information on insomnia and physical activity was self-reported by adolescents.

RESULTS

Our analyses revealed that girls who accumulated at least 60 minutes/day of physical activity on up to three days/week were less prone to present insomnia. This pattern of association was maintained only for those who lived in high HDI regions (odds ratio, 0.87; 95% confidence interval, 0.75-0.99). For boys, there was a positive association between the number of active days and protection against insomnia, especially for those who lived in high HDI regions.

CONCLUSION

Even amounts of physical activity that were lower than the weekly guidelines, were associated with better sleep quality for Brazilian adolescents, especially girls, and even for those who lived in regions with greater social and economic vulnerability.

Influence of Lisdexamfetamine Dimesylate on Early Ejaculation-Results from a Double-Blind Randomized Clinical Trial

BACKGROUND

Among male sexual dysfunctions, erectile dysfunction and early ejaculation have the highest prevalence rates. Here, we tested the influence of lisdexamfetamine dimesylate (Vyas®) on early ejaculation. To this end, we performed a double-blind randomized clinical trial among males with early ejaculation.

METHODS

A total of 46 males with early ejaculation (mean age: 35.23 years) and in stable marital relationships with regular weekly penile-vaginal intercourse were randomly assigned either to the lisdexamfetamine dimesylate condition (30 mg) or to the placebo condition. Compounds were taken about six hours before intended penile-vaginal intercourse. At baseline and four weeks later at the end of the study, participants completed a series of self-rating questionnaires covering early ejaculation. Female partners also rated participants' early ejaculation profile.

RESULTS

Compared to the placebo condition, dimensions of early ejaculation improved over time in the lisdexamfetamine condition, though improvements were also observed in the placebo condition.

CONCLUSIONS

Among male adults in stable marital relationships with regular weekly penile-vaginal intercourse, lisdexamfetamine dimesylate improved dimensions of early ejaculation. Given that improvements were also observed in the placebo condition, psychological factors such as increased attention to early ejaculation and favorable expectations of the compound should be considered.

Sources of Sleep Disturbances and Psychological Strain for Hospital Staff Working during the COVID-19 Pandemic

Hospital staff members reported increased stress-related workload when caring for inpatients with COVID-19 (“frontline hospital staff members”). Here, we tested if depression, anxiety, and stress were associated with poor sleep and lower general health, and if social support mediated these associations. Furthermore, we compared current insomnia scores and general health scores with normative data. A total of 321 full-time frontline hospital staff members (mean age: 36.86; 58% females) took part in the study during the COVID-19 pandemic. They completed a series of questionnaires covering demographic and work-related information, symptoms of depression, anxiety, stress, social support, self-efficacy, and symptoms of insomnia and general health. Higher symptoms of depression, anxiety, and stress were associated with higher symptoms of insomnia and lower general health. Higher scores of depression, anxiety, and stress directly predicted higher insomnia scores and lower general health scores, while the indirect effect of social support was modest. Compared to normative data, full-time frontline hospital staff members had a 3.14 higher chance to complain about insomnia and a significantly lower general health. Symptoms of insomnia and general health were unrelated to age, job experience, educational level, and gender. Given this background, it appears that the working context had a lower impact on individuals’ well-being compared to individual characteristics.
