Night eating syndrome subtypes: differences in binge eating and food addiction symptoms.

PURPOSE: The purpose of the current study was to examine differences in binge eating and food addiction symptoms between Night Eating Syndrome (NES) latent subtypes: evening hyperphagia with nocturnal ingestions (EHNI), evening hyperphagia-only (EHO), and nocturnal ingestions-only (NIO). It was hypothesized that the EHNI group would report more binge eating behaviors and more food addiction symptoms than both the EHO and NIO groups. Further, it was hypothesized that the EHO and NIO groups would differ with the EHO group reporting more binge eating behaviors and the NIO group reporting more food addiction symptoms. METHODS: Participants completed measures online relating to night eating, binge eating, and food addiction. Average age of the final sample was 34.3 (SD = 10.5) and 62.0% were men. Responses to the Night Eating Questionnaire (NEQ; Allison et al., 2008) were used to create an EHNI group (n = 65), an EHO group (n = 32), and a NIO group (n = 69). ANOVAs were conducted to examine between-group differences on disordered eating symptoms. RESULTS: Participants in the EHNI group reported more severe binge eating and food addiction symptoms than those in the EHO and NIO groups. However, there were no significant differences in binge eating or food addiction between the EHO and NIO groups. CONCLUSION: Individuals who meet both NES core criteria (evening hyperphagia and nocturnal ingestions) are likely at a higher risk for experiencing other, more severe disordered eating pathologies. Implications concerning assessment and future research on NES typology are discussed. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

Project STARLIT: protocol of a longitudinal study of habitual sleep trajectories, weight gain, and obesity risk behaviors in college students.

BACKGROUND: Obesity in the United States is a serious and preventable health concern. Previous research suggests that habitual short sleep may influence obesity-risk behaviors, such as increased caloric intake, decreased physical activity and increased engagement in sedentary activities (e.g., media consumption, computer usage). Given that existing longitudinal research studies have methodological concerns preventing conclusive interpretations, Project STARLIT was designed to address these limitations and identify future intervention targets. METHODS: A sample of young adults (n = 300) will be recruited during the summer prior to entering college. Participants will be screened for eligibility requirements prior to the inclusion in the Time 1 assessment though phone and in-person interviews. Once enrolled, participants will complete four assessments over a two year period (i.e., approximately 8, 16 and 24 months after Time 1). Each assessment will consist of one week of data collection including both objective (i.e., habitual sleep, physical activity, body fat composition) and subjective (i.e., sleep diary, 24-h food recall, technology use, and sleep-related beliefs/behaviors) measures. DISCUSSION: Project STARLIT is designed to address methodological concerns of previous research. In addition to clarifying the relationship between habitual short sleep and weight gain among young adults, the proposed study will identify problematic obesity risk behaviors associated with habitual short sleep (e.g., increased caloric intake, physical/sedentary activity). The results will identify prevention or intervention targets related to obesity risk. TRIAL REGISTRATION: ClinicalTrials.gov NCT04100967, 9/23/19, Retrospectively registered.

Difficulties in Emotion Regulation as a Mediator of the Relationship Between Child Sexual Abuse Victimization and Sexual Aggression Perpetration in Male College Students.

Although numerous studies document a link between child sexual abuse and later sexual assault perpetration in men, little research has examined why this relationship exists. One potential mechanism may be emotional regulation difficulties. The current study utilizes a college sample of 132 men to examine the mediating role of emotion regulation difficulties on the relationship between experiencing child sexual abuse and later sexual aggression. Although emotion regulation difficulties in general was not significantly related to sexual aggression, one facet, impulse control difficulties, emerged as a significant mediator of the relationship between child sexual abuse and sexual aggression. Intervention programs should focus on the care that children receive following sexual abuse, with particular emphasis on how emotion regulation abilities may be impacted.

Fear of sleep in first responders: associations with trauma types, psychopathology, and sleep disturbances.

Study Objectives: Fear of sleep contributes to insomnia in some individuals with posttraumatic stress disorder (PTSD) but remains uncharacterized in first responders, a population with high rates of insomnia and PTSD. We evaluated the clinical relevance of fear of sleep in first responders by (1) examining its relationship with trauma types and clinical symptoms and (2) assessing differences in fear of sleep severity between those reporting provisional PTSD, insomnia, or both. Methods: A cross-sectional study of 242 first responders across the United States (59.2% male, 86.4% white, 56.2% law enforcement officers, 98.7% active duty, and Myears of service = 17). Participants completed the Fear of Sleep Inventory-Short Form and measures of trauma history, psychopathology (e.g. PTSD), and sleep disturbances (insomnia and trauma-related nightmares). Results: Fear of sleep was associated with trauma types characterized by interpersonal violence and victimization, as well as symptoms of PTSD, depression, anxiety, stress, alcohol use problems, insomnia, and trauma-related nightmares. Fear of sleep was most pronounced among first responders reporting provisional PTSD comorbid with insomnia compared to those with PTSD or insomnia only. Post hoc analyses revealed PTSD hyperarousal symptoms and trauma-related nightmares were independently associated with fear of sleep, even after adjusting for the remaining PTSD clusters, insomnia, sex, and years of service. Conclusions: Fear of sleep is a clinically relevant construct in first responders that is associated with a broad range of psychopathology symptoms and is most severe among those with cooccurring PTSD and insomnia. Fear of sleep may merit targeted treatment in first responders. This paper is part of the Sleep and Circadian Health in the Justice System Collection.

The relationship between mindfulness, PTSD-related sleep disturbance, and sleep quality: Contributions beyond emotion regulation difficulties.

OBJECTIVE: Emotion regulation difficulties have been associated with traumatic event exposure, posttraumatic stress disorder (PTSD) symptoms, and associated sleep disturbances. Dispositional mindfulness, the tendency to experience the present moment, on purpose with acceptance and nonjudgment, can be conceptualized as adaptive emotion regulation. While dispositional mindfulness has been associated with adaptive posttrauma outcomes, it has not been examined in relation to trauma sequelae, such as sleep disturbance. The current study aimed to expand upon previous research to further explore the relationship between dispositional mindfulness and trauma sequelae. METHOD: Participants (N = 217) were recruited using Amazon's Mechanical Turk to complete online surveys assessing PTSD symptom severity (PTSS), sleep disturbance, emotion regulation difficulties, and mindfulness. RESULTS: After controlling for PTSS, the results suggest that dispositional mindfulness is associated with lower frequency of PTSD-related sleep disturbance and better sleep quality (daily disturbances). Additionally, the results suggest that specific dispositional mindfulness domains remain significant when emotion regulation difficulties domains were included in the model. CONCLUSIONS: Future research should further examine this relationship to inform mindfulness-based interventions for PTSD and sleep disturbance.

Building a Model to Predict Sexual Assault Victimization Frequency Among Undergraduate Women.

Previous research has identified several factors, including sexual risk behaviors, alcohol consumption, sexual refusal assertiveness, impulse control difficulties, drinking to cope, and sex to cope, as being associated with sexual assault victimization. Data were collected from 465 adult, undergraduate women, and analyzed using structural equation modeling to determine how these variables related to one another. Results showed that together, these factors predicted 17.1% of the variance in victimization frequency. These findings may help future researchers better understand the etiology of sexual assault victimization on college campuses and prove crucial to the development of future intervention programs which reduce victimization.

Daytime sleepiness, addictive-like eating, and obesity sequelae in Black and African American youth with obesity.

OBJECTIVES: The purpose of the current study was to examine the association between poor sleep health (ie, excessive daytime sleepiness), obesity sequelae (ie, percent overweight and serum leptin levels), and addictive-like eating behaviors, an obesity phenotype, in a sample of Black/African American (B/AA) adolescents. DESIGN: The current study analyzed archival baseline data from a sample of B/AA adolescents with obesity enrolled in a sequential randomized clinical trial. SETTING: Data were collected in the participants' homes by trained research assistants unaware of treatment condition. PARTICIPANTS: A sample of 181 B/AA adolescents with obesity between the ages of 12 and 16 years (M = 14.26, SD = 1.46) and having a body mass index (BMI) above the 95th percentile for age and gender were sampled. MEASUREMENTS: Self-report measures included the Cleveland Adolescent Sleepiness Questionnaire and the Yale Food Addiction Scale-Children (YFAS-C). Anthropomorphic data and blood samples were used to determine BMI and serum leptin levels, respectively. RESULTS: Excessive daytime sleepiness was positively correlated with YFAS-C symptom count, r = 0.295, P < .001. Serum leptin levels and percent overweight were both positively correlated with each other, r = 0.445, P < .001 and with YFAS-C symptom count, r = 0.215, P = .006. After controlling for age and gender, results supported an indirect effect from daytime sleepiness to both serum leptin levels (estimate = 2.210, SE = 0.932, P = .018) and percent overweight (estimate = 2.817, SE = 1.415, P = .046) through YFAS-C symptom count. CONCLUSIONS: Culturally informed interventions on eating behaviors (ie, addictive-like eating) when excessive daytime sleepiness is reported are needed. Early intervention may help prevent the onset or worsening of obesity among adolescents.

The comparison of brief, online mindfulness and relaxation interventions to reduce stress and improve sleep-related outcomes in college students.

OBJECTIVE: The current study aimed to examine whether brief online stress reduction exercises supplemented with sleep improvement strategies would reduce stress, arousal, and sleep difficulties in college students who were not required to use the sleep improvement strategies for participation. PARTICIPANTS: A sample of 114 college student participants were enrolled because they were experiencing stress and/or wanted to improve their sleep. METHODS: Participants were randomized into an abbreviated progressive muscle relaxation, a mindful breathing, or a self-monitoring control condition for the 4-week intervention. Measures of physical relaxation, mindfulness, perceived stress, pre-sleep arousal, and insomnia symptom severity were collected. RESULTS: The APMR group improved on five of the six dependent measures and was significantly different than the SM group at posttest, but not different than the MB group. CONCLUSION: The results suggests promise for brief, online, scaled back stress reduction interventions to reduce stress, arousal, and sleep difficulties in college students.

Web- and Mindfulness-Based Intervention to Prevent Chronic Pain After Cardiac Surgery: Protocol for a Pilot Randomized Controlled Trial.

BACKGROUND: Cardiac surgery is a frequently performed procedure. However, pain after cardiac surgery may become chronic (lasting >3 months) in adults. Once discharged from the hospital, patients are at greater risk of developing chronic postsurgical pain (CPSP) and of prolonged opioid use, as they need to self-manage their pain. Psychological risk and protective factors such as pain-related catastrophic thoughts and pain acceptance determine their ability to cope and their use of opioids, which is crucial for self-management of pain. Studies on mindfulness-based cognitive therapy (MBCT) have multiplied their potential effects on pain acceptance and catastrophic thoughts. However, web-based MBCT for the prevention of CPSP has not yet been examined. OBJECTIVE: The aim of this study is to pilot test a 4-week-long web-based MBCT intervention for adults following discharge from the hospital by assessing the acceptability or feasibility of the intervention and examining preliminary effects on pain intensity, pain interference with activities and opioid use, and pain acceptance and catastrophic thoughts in the 6 months following surgery. METHODS: A double-blinded pilot randomized controlled trial will be used to assess a web-based MBCT intervention. Patients will be selected according to the following criteria: age ≥18 years; first-time elective cardiac surgery via a median sternotomy; worst pain in the past week score ≥4/10; ability to understand and complete questionnaires in English; and ability to use an electronic device such as a smartphone, computer, or tablet. After baseline measures, 32 participants will be randomized into two groups: one receiving both the brief, 4-week-long web-based MBCT intervention and usual care (experimental group) and the other receiving only one standardized, web-based educational session with weekly reminders and usual care (attention control group). Peer-reviewed competitive funding was received from Florida State University's Council on Research & Creativity in January 2021, as well as research ethics approval from Florida State University's institutional review board. RESULTS: Recruitment began in June 2021. Unfortunately, because of the current COVID-19 pandemic, recruitment is not progressing as expected. Recruitment strategies are constantly monitored and updated according to latest data and restrictions surrounding the pandemic. CONCLUSIONS: This research is significant because it targets the trajectory of CPSP, a leading cause of disability and opioid misuse. This is the first study to assess MBCT for the prevention of CPSP after cardiac surgery in the recovery phase. This approach is innovative because it promotes self-management of pain through the modulation of individual factors. If successful, the intervention could be expanded to numerous populations at risk of chronic pain. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/30951.

Impulse Control Difficulties and Hostility Toward Women as Predictors of Relationship Violence Perpetration in an Undergraduate Male Sample.

Relationship violence in college students continues to be an important social problem. Prior research has identified several risk factors for relationship violence including trauma exposure, impulse control difficulties, and hostility toward women; however, previous research assessing these variables has mainly focused on bivariate relationships, with little work attempting to connect multiple correlates to relationship violence while utilizing a theoretical, interactive approach. The purpose of this study was to simultaneously examine several correlates of relationship violence (i.e., hostility toward women, trauma exposure, and impulse control difficulties), and to examine male perpetration of relationship violence among a sample of male college students using a cross-sectional design. It was hypothesized that among men in this sample, hostility toward women and trauma exposure would moderate the relationship between impulse control difficulties and relationship violence. The findings suggested that college-aged men, who have high impulse control difficulties, high hostility toward women, and who have multiple trauma exposures, may be more likely to perpetrate relationship violence against a female intimate partner than those who are low in impulse control difficulties, report low levels of hostility toward women, or report fewer or no trauma exposures. Thus, the current study suggests that exposure to trauma predisposes men with specific attributes to relationship violence, which may provide a treatment target for future intervention programs.

Potentially morally injurious events and depression symptoms among a trauma-exposed sample: Examining the roles of interpersonal needs and emotion dysregulation.

The current study examined a conceptual model of the association between potentially morally injurious events (PMIEs) and depression symptoms. It was hypothesized that interpersonal needs (i.e., perceived burdensomeness and thwarted belongingness) would independently mediate the relationship between PMIEs and depression symptoms, while emotion dysregulation would moderate the associations. Individuals who experienced a traumatic event and were residing in the United States (N = 147) completed a cross-sectional questionnaire containing measures of PMIEs, interpersonal needs, emotion dysregulation and depression symptoms. Results indicated that the indirect effect through perceived burdensomeness was significant at high levels of emotion dysregulation, whereas the indirect effect through thwarted belongingness was non-significant. Additionally, emotion dysregulation moderated each pathway, with the exception of the direct effects from PMIEs to depression symptoms. The proposed model may be informative for researchers and clinicians interested in the association between PMIEs and depression symptoms. The results may encourage the use of emotion regulation strategies to assist patients suffering from depression symptoms, especially when exposure to a PMIE has occurred.

Mindfulness based art therapy study protocol to determine efficacy in reducing college stress and anxiety.

BACKGROUND: College students in Generation Z are among the most stressed of our time. Previous research suggests that current interventions on university campuses are primarily for students in crises, but supportive services like psychoeducation to introduce coping skills are scant. Interventions that take both financial and time pressures into account are needed to address the mental health challenges faced by students. This study is designed to determine the unique role of the arts as a proactive mental health strategy for college students. METHODS: A sample of college students in Generation Z (n = 120) will be recruited. Participants will be assigned to Arts-only, mindfulness-only, mindfulness-based art interventions or a non-intervention control group. These interventions will be delivered using a minimal contact, web-based approach. Participants will be screened for eligibility requirements prior to the inclusion in the Time 1 assessment though an online survey. Once enrolled, participants will complete the Time 1 assessment, followed by the intervention. Each assessment will consist of psychological and physiological measures. The MBAT, NCT and MO groups will complete a brief self-care task twice a week for 5 weeks. Upon completion of the assigned intervention, participants will complete a Time 2 assessment and participate in the Trier Social Stress Test. Six weeks post-intervention, participants will complete the final assessment to assess the longevity of effects of the intervention. DISCUSSION: This study will clarify the effects of Mindfulness-based Art Therapy on several biometric and physiological markers above and beyond isolated art therapy or mindfulness interventions. Qualitative data in the form of transcribed exit interviews will be analyzed to characterize the unique needs of Generation Z students, along with level of engagement, intervention acceptance and satisfaction. The results will identify the efficacy of a low-cost and easily accessible mental health intervention targeting college students experiencing stress and anxiety.

Morningness-eveningness and social anxiety symptoms: the influence of depression symptoms on the indirect effect through punishment sensitivity and experiential avoidance.

Social anxiety has recently been linked to morningness-eveningness; however, the psychological mechanisms underlying this relationship are not well known. As such, the purpose of the current study is to propose a model by which morningness-eveningness is related to social anxiety symptoms through punishment sensitivity and experiential avoidance within an adult American, community sample recruited via Amazon's Mechanical Turk (MTurk). It was hypothesized that experiential avoidance and punishment sensitivity would be associated with increased social anxiety symptoms and that morningness-eveningness would be negatively related to social anxiety symptoms. Furthermore, eveningness was hypothesized to be associated with increased punishment sensitivity and in turn, greater experiential avoidance. Lastly, the relationship between morningness-eveningness and social anxiety was hypothesized to be mediated by punishment sensitivity among the group with high depression levels, but not among the group with lesser depression symptoms. The results indicated that eveningness was related to social anxiety symptoms through experiential avoidance, and that depression symptoms influenced the relationship between morningness-eveningness and punishment sensitivity such that, in those high in depression symptoms, there was a significant association between eveningness and punishment sensitivity, but not among those with lower depression levels. The study findings build upon existing chronobiological research and addresses inconsistencies in previous literature.

Emotion Regulation Moderates the Relationship Between Alcohol Consumption and the Perpetration of Sexual Aggression.

Sexual assault remains a significant problem on college campuses, and previous research identifies alcohol and emotion regulation as potential contributors to perpetration. Data were collected from 101 male undergraduates, assessing emotion regulation difficulties, sexual aggression perpetration toward women, and alcohol consumption. Results showed that emotion regulation moderated the relationship between alcohol consumption and sexual aggression, such that those with high emotion regulation difficulties were more likely to behave in a sexually aggressive manner. Thus, men with high emotion regulation difficulties may be more likely than those with low difficulties to use alcohol to overcome their inhibitions and perpetrate sexual aggression.

Emotion regulation as a moderator between anxiety symptoms and insomnia symptom severity.

Insomnia is a common concern with many associated negative consequences. Previous research has established bivariate relationships between anxiety symptoms, emotion regulation, and insomnia symptom severity; however, limited research has examined how the interaction between emotion regulation and anxiety symptoms may be associated with insomnia symptom severity. A sample of 468 undergraduate participants and a subsample of 136 participants meeting a self-reported cutoff score for insomnia, completed questionnaires assessing anxiety, insomnia symptom severity, and emotion regulation difficulties. Among the general sample of all participants, the interaction between anxiety symptoms and both overall emotion regulation difficulties and limited access to emotion regulation strategies were associated with insomnia symptom severity. However, among the insomnia subsample, emotion regulation moderated this relationship, such that insomnia symptom severity increased as anxiety symptoms increased among those with high emotion regulation difficulties, but were unaffected by changes in anxiety symptoms among those with low emotion regulation difficulties. These findings suggest that maladaptive emotion regulation may be necessary for anxiety symptoms to have a negative influence on sleep difficulties, meaning that during treatment, it may be important to address both an individual's anxiety symptoms and emotion regulation difficulties, particularly among those with clinical levels of insomnia.

The relationship between subjective sleep disturbance, sleep quality, and emotion regulation difficulties in a sample of college students reporting trauma exposure.

Sleep disturbance and poor sleep quality has been associated with trauma exposure and posttraumatic stress disorder (PTSD) symptoms; however, the associated emotional consequences of sleep disturbance have not been examined within this context (i.e., emotional reactivity, emotion modulation). The current study examined the relationship between sleep disturbance, poor sleep quality, and emotion regulation difficulties. In a sample of college students reporting exposure to at least 1 traumatic event, online survey methodology was used to assess PTSD symptom severity (PTSS), sleep disturbances, including PTSD-specific sleep disturbances, and emotion regulation difficulties. After controlling for PTSS, sleep disturbance and poor sleep quality domains were related to both global and specific difficulties in emotion regulation domains. The findings suggest that sleep disturbance and emotion regulation difficulties associated with PTSD may not be a mere extension of the clinical picture of PTSD. Sleep disturbances following trauma exposure may contribute to emotion regulation difficulties and exacerbate negative consequences. Future research should examine the effects of treatments that simultaneously address sleep disturbances and PTSD symptoms on emotion regulation processes.

Female-perpetrated intimate partner violence and romantic attachment style in a college student sample.

The frequency, severity, and reciprocity of female-perpetrated intimate partner violence and its consequences (i.e., injuries) were investigated in a college sample of women (N = 457). Participants were classified into one of the following four groups on the basis of self-reported physical assault perpetration and victimization against their relationship partners: nonviolent, perpetrator-only, victim-only, and bidirectionally violent. Results showed that females in the bidirectionally violent group had a reportedly higher occurrence (although not always statistically significant) of perpetration and victimization than those in the perpetrator-only and victim-only groups. Additionally, a similar degree of reciprocity was indicated by females in bidirectionally violent relationships in terms of violence severity and the occurrence of injury. Adult romantic attachment style was also examined among a subset of females (N = 328), and bidirectionally violent females were found to have the highest reported levels of attachment anxiety. Further, females high in attachment anxiety and low in attachment avoidance were more likely to report perpetrating violence than females high in both styles. Implications for prevention are discussed.

A model of BIS/BAS sensitivity, emotion regulation difficulties, and depression, anxiety, and stress symptoms in relation to sleep quality.

Recent research has indicated that interactions between behavioral inhibition system (BIS)/behavioral activation system (BAS) sensitivity and emotion regulation (ER) difficulties increases risk for psychopathology. Considering sleep quality (SQ) has been linked to emotion regulation difficulties (ERD) and psychopathology, further investigation of a possible mechanism is needed. The current study examined associations between BIS/BAS sensitivity, ERD, and SQ to depression, anxiety, and stress symptoms in an undergraduate sample (n=459). Positive relationships between BIS sensitivity and both ERD and stress symptoms, and negative relationships between BAS-reward sensitivity and both ERD and depression symptoms were observed. Furthermore, ERD were positively related to depression, anxiety, and stress symptoms. Succeeding analyses revealed differential relationships between ERD and depression, anxiety, and stress symptoms among good quality and poor quality sleepers. The findings are discussed within the context of personality dimensions and self-regulatory mechanisms, along with implications for the treatment of depression, anxiety and sleep difficulties.

Experiential avoidance as a moderator of the relationship between behavioral inhibition system sensitivity and posttraumatic stress symptoms.

Preliminary evidence suggests that high emotional reactivity, in conjunction with maladaptive self-regulatory processes, increases one's vulnerability to develop psychopathology. In the present study, associations between behavioral inhibition system (BIS) and behavioral activation system (BAS) sensitivity, experiential avoidance (EA) and trauma-related outcomes (i.e., posttraumatic stress symptoms [PTSS]) were examined in a sample (N=851) of female college students who had experienced at least one traumatic event. Positive associations were observed between BIS sensitivity, EA, and PTSS. In addition, EA moderated the relationship between BIS sensitivity and PTSS, with participants high in BIS sensitivity and high in EA reporting significantly more PTSS than participants high in BIS sensitivity and low in EA. No association was observed between BIS sensitivity and PTSS for participants low in EA. These findings suggest that an unwillingness to experience unwanted private events, in conjunction with increased BIS sensitivity, contributes to PTSS severity. Further, there was a positive association and a negative association found between PTSS and BAS-Drive and BAS-Reward Responsiveness, respectively. A marginally significant EA×BAS-Fun Seeking interaction was also observed. Present findings suggests the importance of pursuing an etiological model of posttraumatic stress disorder in which neurobiological factors (i.e., BIS/BAS sensitivity) and self-regulatory processes (i.e., EA) interact to produce psychopathology.
