Alcohol use and intimate partner violence victimization among young adults with a history of perpetration: An ecological momentary assessment study.

BACKGROUND: Intimate partner violence (IPV) is a major public health concern among young adults and has shown a consistent association with alcohol use. However, previous research has used cross-sectional and daily diary designs that may fail to pinpoint the effects of alcohol use within several hours of IPV occurring. The present study used novel ecological momentary assessment (EMA) methods to investigate the bidirectional effect of alcohol use and IPV victimization among young adults with a history of IPV perpetration. METHODS: One hundred and sixty-eight young adults (age 18-25 years) in a dating relationship who reported IPV perpetration in the past year completed 28 days of randomly prompted EMA surveys (four surveys daily). The effect of alcohol use on IPV victimization and the effect of IPV victimization on alcohol use were examined. RESULTS: The results indicated that alcohol use co-occurs with psychological and physical IPV victimization. Further, alcohol use significantly increased the odds of physical (OR = 4.94; 95% CI = 2.24-10.87) and sexual (OR = 4.66; 95% CI = 1.64-13.22) IPV victimization, but not psychological IPV victimization, in the subsequent EMA survey. Finally, IPV victimization did not significantly increase the odds of reporting alcohol use in the subsequent EMA survey. CONCLUSIONS: Using alcohol is proximally related to IPV victimization among those with a history of IPV perpetration. Intervention efforts would benefit from adapting EMA methods to provide resources the moment they are needed.

Blood-based DNA methylation and exposure risk scores predict PTSD with high accuracy in military and civilian cohorts.

BACKGROUND: Incorporating genomic data into risk prediction has become an increasingly popular approach for rapid identification of individuals most at risk for complex disorders such as PTSD. Our goal was to develop and validate Methylation Risk Scores (MRS) using machine learning to distinguish individuals who have PTSD from those who do not. METHODS: Elastic Net was used to develop three risk score models using a discovery dataset (n = 1226; 314 cases, 912 controls) comprised of 5 diverse cohorts with available blood-derived DNA methylation (DNAm) measured on the Illumina Epic BeadChip. The first risk score, exposure and methylation risk score (eMRS) used cumulative and childhood trauma exposure and DNAm variables; the second, methylation-only risk score (MoRS) was based solely on DNAm data; the third, methylation-only risk scores with adjusted exposure variables (MoRSAE) utilized DNAm data adjusted for the two exposure variables. The potential of these risk scores to predict future PTSD based on pre-deployment data was also assessed. External validation of risk scores was conducted in four independent cohorts. RESULTS: The eMRS model showed the highest accuracy (92%), precision (91%), recall (87%), and f1-score (89%) in classifying PTSD using 3730 features. While still highly accurate, the MoRS (accuracy = 89%) using 3728 features and MoRSAE (accuracy = 84%) using 4150 features showed a decline in classification power. eMRS significantly predicted PTSD in one of the four independent cohorts, the BEAR cohort (beta = 0.6839, p=0.006), but not in the remaining three cohorts. Pre-deployment risk scores from all models (eMRS, beta = 1.92; MoRS, beta = 1.99 and MoRSAE, beta = 1.77) displayed a significant (p < 0.001) predictive power for post-deployment PTSD. CONCLUSION: The inclusion of exposure variables adds to the predictive power of MRS. Classification-based MRS may be useful in predicting risk of future PTSD in populations with anticipated trauma exposure. As more data become available, including additional molecular, environmental, and psychosocial factors in these scores may enhance their accuracy in predicting PTSD and, relatedly, improve their performance in independent cohorts.

Epigenome-wide association studies identify novel DNA methylation sites associated with PTSD: A meta-analysis of 23 military and civilian cohorts.

Background: The occurrence of post-traumatic stress disorder (PTSD) following a traumatic event is associated with biological differences that can represent the susceptibility to PTSD, the impact of trauma, or the sequelae of PTSD itself. These effects include differences in DNA methylation (DNAm), an important form of epigenetic gene regulation, at multiple CpG loci across the genome. Moreover, these effects can be shared or specific to both central and peripheral tissues. Here, we aim to identify blood DNAm differences associated with PTSD and characterize the underlying biological mechanisms by examining the extent to which they mirror associations across multiple brain regions. Methods: As the Psychiatric Genomics Consortium (PGC) PTSD Epigenetics Workgroup, we conducted the largest cross-sectional meta-analysis of epigenome-wide association studies (EWASs) of PTSD to date, involving 5077 participants (2156 PTSD cases and 2921 trauma-exposed controls) from 23 civilian and military studies. PTSD diagnosis assessments were harmonized following the standardized guidelines established by the PGC-PTSD Workgroup. DNAm was assayed from blood using either Illumina HumanMethylation450 or MethylationEPIC (850K) BeadChips. A common QC pipeline was applied. Within each cohort, DNA methylation was regressed on PTSD, sex (if applicable), age, blood cell proportions, and ancestry. An inverse variance-weighted meta-analysis was performed. We conducted replication analyses in tissue from multiple brain regions, neuronal nuclei, and a cellular model of prolonged stress. Results: We identified 11 CpG sites associated with PTSD in the overall meta-analysis (1.44e-09 < p < 5.30e-08), as well as 14 associated in analyses of specific strata (military vs civilian cohort, sex, and ancestry), including CpGs in AHRR and CDC42BPB. Many of these loci exhibit blood-brain correlation in methylation levels and cross-tissue associations with PTSD in multiple brain regions. Methylation at most CpGs correlated with their annotated gene expression levels. Conclusions: This study identifies 11 PTSD-associated CpGs, also leverages data from postmortem brain samples, GWAS, and genome-wide expression data to interpret the biology underlying these associations and prioritize genes whose regulation differs in those with PTSD.

Measuring emotion dysregulation in daily life: an experience sampling study.

BACKGROUND: Literature underscores the importance of emotion dysregulation in clinical research. However, one critical limitation of the existing investigations in this area involves the lack of psychometrically valid measures for assessing emotion dysregulation in individuals' daily lives. This study examined the factor structure and psychometric properties of momentary versions of the Difficulties in Emotion Regulation Scale (mDERS) and the Difficulties in Emotion Regulation Scale-Positive (mDERS-P). METHODS: Participants were 145 community women (M age = 40.66, 40.7% white) experiencing intimate partner violence and using substances who participated in a baseline interview and then completed surveys three times a day for 30 days. RESULTS: Analyses supported the reliability of the mDERS and the mDERS-P. The two-state, two-trait model, with separate factors for negative and positive emotion dysregulation at both the within-and between-levels, fit the data best. Momentary negative, but not positive, emotions were positively related to the mDERS; both momentary negative and positive emotions were positively related to the mDERS-P. Baseline trait negative, but not positive, emotion dysregulation, was related to greater variability in momentary negative and positive emotion dysregulation. CONCLUSION: Findings advance our understanding and measurement of emotion dysregulation using intensive longitudinal approaches.

Same-Day and Next-Day Associations Between Relational Factors and Intimate Partner Violence in Young Adult Couples.

Objective: The prevalence of intimate partner violence (IPV) is high, with young adults at increased risk. IPV is largely understood as a dyadic process, as it involves both partners and is inherently influenced by the behaviors of both partners. The objective of this study was to examine the proximal influence of relationship satisfaction and conflict on same-day and nextday IPV perpetration among young adult couples. Method: This study used data from young adult couples (N = 172) who completed a 60-day daily-diary design. The Actor Partner Interdependence Model was used to examine whether within- and between-person levels of relationship satisfaction and conflict were associated with same-day and next-day IPV perpetration. Results: Results suggest that high levels of one's own and one's partner's relationship satisfaction was associated with low levels of same-day and next-day psychological IPV. For women, but not men, high levels in their own and their partner's relationship satisfaction were associated with low levels in same-day physical IPV perpetration. Conversely, high levels in one's own and their partner's conflict was associated with high levels of same-day psychological IPV perpetration. For women, but not men, high levels in their partner's conflict were associated with high levels of same-day physical IPV perpetration. Conclusion: Results suggest that relationship dissatisfaction and conflict may be proximal risk factors for IPV perpetration, particularly psychological IPV perpetration, implying these factors may be effective targets for prevention and intervention.

Daily Levels and Dynamic Metrics of Affective-Cognitive Constructs Associate With Suicidal Thoughts and Behaviours in Adults After Psychiatric Hospitalization.

The period after psychiatric hospitalization is an extraordinarily high-risk period for suicidal thoughts and behaviours (STBs). Affective-cognitive constructs (ACCs) are salient risk factors for STBs, and intensive longitudinal metrics of these constructs may improve personalized risk detection and intervention. However, limited research has examined how within-person daily levels and between-person dynamic metrics of ACCs relate to STBs after hospital discharge. Adult psychiatric inpatients (N = 95) completed a 65-day ecological momentary assessment protocol after discharge as part of a 6-month follow-up period. Using dynamic structural equation models, we examined both within-person daily levels and between-person dynamic metrics (intensity, variability and inertia) of positive and negative affect, rumination, distress intolerance and emotion dysregulation as risk factors for STBs. Within-person lower daily levels of positive affect and higher daily levels of negative affect, rumination, distress intolerance and emotion dysregulation were risk factors for next-day suicidal ideation (SI). Same-day within-person higher rumination and negative affect were also risk factors for same-day SI. At the between-person level, higher overall positive affect was protective against active SI and suicidal behaviour over the 6-month follow-up, while greater variability of rumination and distress intolerance increased risk for active SI, suicidal behaviour and suicide attempt. The present study provides the most comprehensive examination to date of intensive longitudinal metrics of ACCs as risk factors for STBs. Results support the continued use of intensive longitudinal methods to improve STB risk detection. Interventions focusing on rumination and distress intolerance may specifically help to prevent suicidal crises during critical transitions in care.

Micro-sequences of anger and shame and non-suicidal self-injury in youth: an ecological momentary assessment study.

OBJECTIVE: Non-suicidal self-injury (NSSI) is a significant mental health concern with the highest prevalence among adolescents. NSSI has been conceptualized as one of the maladaptive strategies to cope with challenging affect or a form of self-punishment. Although characterizing moment-to-moment associations between shame and NSSI in individuals' real-world environment and partitioning between- and within-person effects is critical for mobile and timely interventions, most studies examined habitual experiences of negative affective states and focused on adults. METHOD: In this study, we focused on in vivo anger at self and others and shame and NSSI among 158 adolescents 3 weeks following their psychiatric hospitalizations using ecological momentary assessment (EMA) technology. RESULTS: We found that greater between-person levels of anger at self and others were linked to a higher number of subsequent NSSI occurrences within a day. These findings remained primarily unchanged when we statistically adjusted for participants' age, sex assigned at birth, the number of current psychiatric diagnoses, EMA response rates, and youth lifetime history of SI. Within-person increases in NSSI were linked to increased anger at self over and beyond between-person average levels of NSSI. CONCLUSIONS: These findings highlight the potential regulatory role of NSSI to decrease negative affective states and point to the clinical utility of assessing and early mobile interventions targeting challenging affect in youth.

Designing a Clinician-Centered Wearable Data Dashboard (CarePortal): Participatory Design Study.

BACKGROUND: The recent growth of eHealth is unprecedented, especially after the COVID-19 pandemic. Within eHealth, wearable technology is increasingly being adopted because it can offer the remote monitoring of chronic and acute conditions in daily life environments. Wearable technology may be used to monitor and track key indicators of physical and psychological stress in daily life settings, providing helpful information for clinicians. One of the key challenges is to present extensive wearable data to clinicians in an easily interpretable manner to make informed decisions. OBJECTIVE: The purpose of this research was to design a wearable data dashboard, named CarePortal, to present analytic visualizations of wearable data that are meaningful to clinicians. The study was divided into 2 main research objectives: to understand the needs of clinicians regarding wearable data interpretation and visualization and to develop a system architecture for a web application to visualize wearable data and related analytics. METHODS: We used a wearable data set collected from 116 adolescent participants who experienced trauma. For 2 weeks, participants wore a Microsoft Band that logged physiological sensor data such as heart rate (HR). A total of 834 days of HR data were collected. To design the CarePortal dashboard, we used a participatory design approach that interacted directly with clinicians (stakeholders) with backgrounds in clinical psychology and neuropsychology. A total of 8 clinicians were recruited from the Rhode Island Hospital and the University of Massachusetts Memorial Health. The study involved 5 stages of participatory workshops and began with an understanding of the needs of clinicians. A User Experience Questionnaire was used at the end of the study to quantitatively evaluate user experience. Physiological metrics such as daily and hourly maximum, minimum, average, and SD of HR and HR variability, along with HR-based activity levels, were identified. This study investigated various data visualization graphing methods for wearable data, including radar charts, stacked bar plots, scatter plots combined with line plots, simple bar plots, and box plots. RESULTS: We created a CarePortal dashboard after understanding the clinicians' needs. Results from our workshops indicate that overall clinicians preferred aggregate information such as daily HR instead of continuous HR and want to see trends in wearable sensor data over a period (eg, days). In the User Experience Questionnaire, a score of 1.4 was received, which indicated that CarePortal was exciting to use (question 5), and a similar score was received, indicating that CarePortal was the leading edge (question 8). On average, clinicians reported that CarePortal was supportive and can be useful in making informed decisions. CONCLUSIONS: We concluded that the CarePortal dashboard integrated with wearable sensor data visualization techniques would be an acceptable tool for clinicians to use in the future.

Longitudinal assessment of the sleep suicide link in Veterans: methods and study protocol.

Although sleep disruption has emerged as a theoretically consistent and empirically supported suicide risk factor, the mechanistic pathways underlying the sleep-suicide link are less understood. This paper describes the methodology of a study intended to examine longitudinal mechanisms driving the link between sleep and suicide in Veterans at elevated suicide risk. Participants will be 140 Veterans hospitalized for suicide attempt or ideation with plan and intent or those identified through the Suicide Prevention Coordinator (SPC) office as being at acute risk. After study enrollment, actigraphy and ecological momentary assessment (EMA) data will be collected for 8 weeks, with follow-up assessments occurring at 2, 4, 6, 8, and 26 weeks. Participants respond to EMA questionnaires, derived from psychometrically validated assessments targeting emotional reactivity, emotion regulation, impulsivity, suicide risk, and sleep timing constructs, five times a day. First and last daily EMA target sleep parameters including sleep quantity, quality, timing, nightmares, and nocturnal awakenings. During follow-up assessments, participants will complete self-report assessments and interviews consistent with EMA constructs and the Iowa Gambling Task. The primary outcome for aim 1 is suicide ideation severity and for the primary outcome for aim 2 is suicide behavior. Findings from this study will improve our understanding of the dynamic interactions among sleep disturbance, emotion reactivity/regulation, and impulsivity to inform conceptual Veteran sleep-suicide mechanistic models. Improved models will be critical to optimizing the precision of suicide prevention efforts that aim to intervene and mitigate risk in Veteran populations, especially during a period of acute risk.

A randomized trial of acceptance-based behavioral therapy to improve mental health outcomes for LGBTQ+ persons: Study protocol.

BACKGROUND: During the COVID-19 pandemic, public health measures limited social interactions as an effective and protective intervention for all. For many, however, this social isolation exacerbated mental health symptoms. People who identify as lesbian, gay, bisexual, transgender, and queer (LGBTQ+) were already at elevated risk of anxiety and depression, relative to cisgender and heterosexual populations, and pandemic-related social isolation likely heightened these disparities. In our prior work with sexual and gender minorities, we developed and established feasibility and acceptability of a novel acceptance-based behavioral therapy (ABBT) intervention for HIV treatment. ABBT showed promise in improving social support and reducing mental health symptoms. In the current study, we investigate the efficacy of ABBT, compared to a treatment-as-usual control condition, in a full-scale randomized controlled trial to improve social support for LGBTQ+ persons living with anxiety and depression. METHODS: Two hundred forty LGBTQ+ adults with anxiety and/or depressive symptoms will be recruited and equally randomized to receive: (a) the ABBT intervention, consisting of two 30-40 min sessions plus treatment-as-usual (TAU), or (b) TAU only. Primary outcomes are interviewer-assessed anxiety and depressive symptoms. Secondary outcomes are self-reported anxiety and depressive symptoms. Experiential avoidance and social support are hypothesized mediators and presence of an anxiety and/or depressive disorder is a hypothesized moderator. CONCLUSIONS: ABBT represents a novel, identify-affirming real-world approach to promoting social support as a means of improving mental health among individuals who identify as LGBTQ+. This study will contribute actionable data establishing the impact, mediational mechanisms, and effect modifiers of ABBT. CLINICALTRIALS: govregistration: NCT05540067.

Genetic associations among internalizing and externalizing traits with polysubstance use among young adults.

Though most genetic studies of substance use focus on specific substances in isolation or generalized vulnerability across multiple substances, few studies to date focus on the concurrent use of two or more substances within a specified time frame (i.e., polysubstance use; PSU). We evaluated whether distinct genetic factors underlying internalizing and externalizing traits were associated with past 30-day PSU above variance shared across general psychopathology and substance use (SU). Using Genomic Structural Equation Modeling, we constructed theory-driven, multivariate genetic factors of 16 internalizing, externalizing, and SU traits using genome-wide association studies (GWAS) summary statistics. Next, we fit a model with a higher order SU-related psychopathology factor as well as genetic variance specific to externalizing and internalizing (i.e., residual genetic variance not explained by SU or general psychopathology). GWAS-by-subtraction was used to obtain single nucleotide polymorphism effects on each of these factors. Polygenic scores (PGS) were then created in an independent target sample with data on PSU, the National Longitudinal Study of Adolescent to Adult Health. To evaluate the effect of genetic variance due to internalizing and externalizing traits independent of variance related to SU, we regressed PSU on the PGSs, controlling for sex, age, and genetic principal components. PGSs for SU-related psychopathology and non-SU externalizing traits were associated with higher PSU factor scores, while the non-SU internalizing PGS was not significantly associated with PSU. In total, the three PGSs accounted for an additional 4% of the variance in PSU above and beyond a null model with only age, sex, and genetic principal components as predictors. These findings suggest that there may be unique genetic variance in externalizing traits contributing to liability for PSU that is independent of the genetic variance shared with SU.

A daily diary study of minority stressors, suicidal ideation, nonsuicidal self-injury ideation, and affective mechanisms among sexual and gender minority youth.

Sexual and gender minority youth (SGMY) are at greater risk than their heterosexual and cisgender counterparts for suicidal thoughts and behaviors (STB) and nonsuicidal self-injury (NSSI). Unique stressors (i.e., minority stressors) specific to SGMY's stigmatized identities such as discrimination or concealment of one's identity are posited to explain these disparities. However, there is limited research examining the associations among minority stressors, affective mediating processes, and STB and NSSI in SGMY's daily lives. We conducted a 28-day daily diary study to test the mediating effects of daily negative and positive affect and emotion dysregulation between minority stressors and STB and NSSI among SGMY who were recruited from clinical and community settings. Participants were 92 SGMY, aged 12-19 years old (M = 16.45; SD = 1.81; 64% cisgender; 69% White). Results indicated that on days SGMY experienced external and internalized minority stressors, they reported greater intensity of suicidal and nonsuicidal self-injurious ideation and affective distress (i.e., greater negative affect, lower positive affect, and more emotion dysregulation). Greater affective reactivity processes were associated with greater suicidal and nonsuicidal self-injurious ideation intensity on the same day. Most of the within-person associations between external and internalized minority stressors and ideation intensity were mediated by heightened negative affect and emotion dysregulation but not lower positive affect. Our results provide the first evidence of these associations among SGMY, advance the minority stress model, and have implications for clinical interventions as we identified modifiable affective mechanisms.

Ecological Momentary Assessment of Cannabis Use and Affect Among Adolescents Following Psychiatric Discharge.

OBJECTIVE: Affect regulation is central to multiple theoretical models that explain cannabis use (CU) behavior. However, much of the research has been conducted with adults, leaving unanswered questions about the nature of associations among adolescents, especially those with affective disorders. Using clinical interviews and ecological momentary assessment (EMA), we assessed rates of adolescent CU and momentary associations with affect following psychiatric discharge among youth hospitalized for suicidal thoughts and behaviors. METHOD: Participants were 13- to 18-year-olds (N = 62; 64.5% female) recruited from an inpatient psychiatric hospital who reported having ever used cannabis. Participants completed clinical interviews during hospitalization. EMA was conducted for 21 days upon discharge. RESULTS: Concurrent use of other drugs was associated with greater odds of CU (odds ratio = 27.63). Momentary CU was associated with higher levels of positive affect and lower levels of anger/irritability, but not with negative affect. The effect of momentary CU on positive affect was greater among youth with a diagnosis of posttraumatic stress disorder (PTSD) or generalized anxiety disorder (GAD). CONCLUSIONS: Findings suggest that adolescents may use cannabis to enhance positive emotion, especially those with PTSD/GAD. Results highlight the importance of tailored interventions that focus on providing alternative and adaptive methods to enhance positive affect.

Attentional biases for sad faces in offspring of mothers with a history of major depression: trajectories of change from childhood to adolescence.

BACKGROUND: Theorists have proposed that the way children process social-emotional information may serve as a mechanism of risk for the intergenerational transmission of depression. There is growing evidence that infants and children of mothers with a history of major depressive disorder (MDD) during the child's life exhibit attentional avoidance of sad faces, which has been proposed as an early emerging emotion regulation strategy. In contrast, there is clear evidence that at-risk and depressed adolescents and adults exhibit difficulty disengaging attention from sad faces. METHODS: Seeking to link these two literatures, the current U.S.-based study used eye tracking within the context of an accelerated longitudinal design to assess attentional biases in 8-14-year-old offspring of mothers with a history MDD during the child's life (n = 123) or no history of MDD (n = 119) every six months for two years, allowing us to map trajectories of attention from age 8 to 16. RESULTS: Mother MDD history moderated age-based changes in children's gaze duration to sad (t[240] = 2.44, p = .02), but not happy (t[240] = 0.11, p = .91) or angry (t[240] = 0.67, p = .50), faces. Consistent our hypotheses, offspring of mothers with MDD exhibited significantly less attention to sad faces than offspring of never depressed mothers before age 8.5 but significantly more attention to sad faces after age 14.5, which was due to an increase in gaze duration to sad faces from childhood to adolescence among offspring of mothers with MDD (t[122] = 5.44, p < .001) but not among offspring of never depressed mothers (t[118] = 1.49, p = .14). CONCLUSIONS: It appears that the form, and perhaps function, of attentional bias may shift across development in at-risk youth. To the extent that this is true, it has significant implications not only for theories of the intergenerational transmission of depression risk but also for prevention and early intervention efforts designed to reduce this risk.

Implementation and outcomes of home-based treatments for adolescents with anorexia nervosa: Study protocol for a pilot effectiveness-implementation trial.

OBJECTIVE: Although family-based treatment (FBT) is considered a first-line treatment for adolescent anorexia nervosa (AN), it is underutilized in community settings and is unavailable to many families for a multitude of practical reasons (e.g., costs of treatment, transportation constraints). Adapting FBT interventions for delivery in home-based and community-based settings may reduce pragmatic barriers to treatment uptake and engagement. METHODS: This pilot effectiveness-implementation trial will assess outcomes, implementation, and mechanisms of FBT adapted for the home setting (FBT-HB), delivered in the context of community-based behavioral health agencies. Adolescents with AN-spectrum disorders (n = 50) and their caregivers will be randomly assigned to either FBT-HB or home-based treatment as usual (TAU; integrated family therapy approach). Caregivers and adolescents will provide data on weight, eating, and putative treatment mechanisms, including caregiver self-efficacy and adolescent eating-related and weight-related distress. Implementation constructs of feasibility, acceptability, and appropriateness will be measured among providers and participating families. HYPOTHESES: We expect that FBT-HB will be feasible, acceptable, and appropriate, and will outperform TAU in terms of improvements in adolescent weight and eating-related psychopathology. We further expect that caregiver self-efficacy and adolescent eating-related and weight-related distress, but not general distress, will show greater improvements in FBT-HB relative to TAU and will be associated with better adolescent weight and eating outcomes in FBT-HB. POTENTIAL IMPLICATIONS: The proposed study has clear potential to advance scientific and clinical understanding of the real-world effectiveness of FBT for AN, including whether adapting it for the home setting improves its accessibility and effects on treatment outcome.

Dry Bean: A Protein-Rich Superfood With Carbohydrate Characteristics That Can Close the Dietary Fiber Gap.

Consumer food choices are often focused on protein intake, but the chosen sources are frequently either animal-based protein that has high fat content or plant-based protein that is low in other nutrients. In either case, these protein sources often lack dietary fiber, which is a nutrient of concern in the 2020-2025 Dietary Guide for Americans. Pulse crops, such as dry edible beans (Phaseolus vulgaris L.), are a rich source of dietary protein and contain approximately equal amounts of dietary fiber per 100 kcal edible portion; yet the consumer's attention has not been directed to this important fact. If product labeling were used to draw attention to the similar ratio of dietary protein to dietary fiber in dry bean and other pulses, measures of carbohydrate quality could also be highlighted. Dietary fiber is categorized into three fractions, namely, soluble (SDF), insoluble (IDF), and oligosaccharides (OLIGO), yet nutrient composition databases, as well as food labels, usually report only crude fiber. The objectives of this research were to measure the content of SDF, IDF, and OLIGO in a large genetically diverse panel of bean cultivars and improved germplasm (n = 275) and determine the impact of growing environment on the content of DF. Dietary fiber was evaluated using the American Association of Analytical Chemist 2011.25 method on bean seed grown at two locations. Dry bean cultivars differed for all DF components (P ≤ 0.05). Insoluble dietary fiber constituted the highest portion of total DF (54.0%), followed by SDF (29.1%) and OLIGO (16.8%). Mean total DF and all components did not differ among genotypes grown in two field environments. These results indicate that value could be added to dry bean by cultivar-specific food labeling for protein and components of dietary fiber.

Posttraumatic stress disorder strengthens the momentary associations between emotion dysregulation and substance use: a micro-longitudinal study of community women experiencing intimate partner violence.

BACKGROUND AND AIMS: A fast-growing body of literature linking emotion dysregulation to substance use has almost exclusively relied on cross-sectional designs and has generally failed to assess dysregulation stemming from positive emotions. The current study measured the momentary associations between both negative and positive emotion dysregulation and substance use, as well as the moderating role of post-traumatic stress disorder (PTSD). DESIGN: Micro-longitudinal momentary data were collected three times per day for 30 days using phone-based interactive voice recording. SETTING: Northeastern United States. PARTICIPANTS: A total of 145 community women (M, age = 40.56, 40.3% white) experiencing intimate partner violence (IPV) and using substances were recruited from 2018 until 2020. MEASUREMENTS: Momentary surveys assessed negative and positive emotion dysregulation and alcohol, drug, and cigarette use. PTSD diagnosis was derived from a structured diagnostic interview. FINDINGS: Between-person relations that remained significant after covariate adjustment and correction for multiple testing were found for negative emotion dysregulation and both number of drinks (internal rate of return [IRR] = 1.45; 95% CI = 1.07, 1.93; ß = 0.37) and drug use (OR = 3.78; 95% CI = 1.86, 7.69; ß = 1.33), and positive emotion dysregulation and number of cigarettes (OR = 1.40; 95% CI = 1.07, 1.82; ß = 0.34). Of six interactions tests, PTSD was only shown to moderate the within-person relation between positive emotion dysregulation and drug use, even after controlling for relevant covariates and adjusting for multiple testing (OR = 1.26; 95% CI = 1.04, 1.51; ß = 0.23), such that women experiencing intimate partner violence with versus without PTSD were more likely to use drugs when experiencing periods of elevated positive emotion dysregulation. CONCLUSIONS: Women experiencing intimate partner violence with higher levels of negative dysregulation relative to others may use more alcohol and be more likely to use drugs. Women experiencing intimate partner violence with higher levels of positive dysregulation relative to others may use more cigarettes. Women experiencing intimate partner violence who also have posttraumatic stress disorder may be more likely to use drugs when experiencing momentary elevated levels of positive emotion dysregulation than those who do not also have posttraumatic stress disorder.

Modeling reciprocal relations between emotion dysregulation and alcohol use using dynamic structural equation modeling: A micro-longitudinal study.

BACKGROUND: Research examining emotion dysregulation and alcohol use has increased exponentially over the past decade. However, these studies have been limited by their use of cross-sectional designs and narrow definitions of emotion dysregulation. To address these significant gaps in the extant literature, this study utilized state-of-the-art methodology (i.e., experience sampling) and statistics (i.e., dynamic structural equation modeling) to examine potential reciprocal associations between negative and positive emotion dysregulation and alcohol use at the momentary level. METHODS: Participants were 145 community women (mean age = 40.56, 40.3% white) experiencing intimate partner violence (IPV) and using substances. Surveys assessing negative and positive emotion dysregulation and alcohol use (i.e., number of standard drinks) were administered three times a day for 30 days using phone-based interactive voice recording. RESULTS: Significant contemporaneous effects indicated that negative and positive emotion dysregulation both co-occurred with alcohol use. However, levels of negative and positive emotion dysregulation did not predict later alcohol use, nor did alcohol use predict later levels of negative or positive emotion dysregulation. There was significant variability among participants in cross-lagged effects. CONCLUSIONS: Findings showed that negative and positive emotion dysregulation co-occurred with alcohol use and that there was significant interindividual variability in the cross-lagged associations between negative and positive emotion dysregulation and alcohol use. Research using idiographic approaches may identify women experiencing IPV for whom negative and positive emotion dysregulation drive alcohol use and alcohol use drives negative and positive emotion dysregulation.

Dynamic Regulatory Processes in the Transition From Suicidal Ideation to Action in Adults Leaving Inpatient Psychiatric Care: Protocol for an Intensive Longitudinal Study.

BACKGROUND: US suicide rates have risen steadily in the past decade, and suicide risk is especially high in the months after discharge from inpatient psychiatric treatment. However, suicide research has lagged in examining dynamic within-person processes that contribute to risk over time among individuals known to be at high risk of suicide. Almost no research has examined how affective, cognitive, and physiological processes change over minutes, hours, or days to confer risk of suicidal behavior in daily life. OBJECTIVE: This protocol describes a longitudinal study designed to examine real-world changes in risk of suicide across multiple assessment domains. Specifically, the study involves following adults known to be at high risk of suicide after discharge from inpatient psychiatric care using self-report, interview, actigraphy, and behavioral methods to identify proximal contributors to suicidal thoughts and behaviors. First, we hypothesize that negative affective experiences, which are featured in most major suicide theories, will comprise a latent factor indicative of psychache (emotional pain), which will predict increases in suicidal thinking over time. Second, we hypothesize that poor inhibitory control in the context of negative affective stimuli, as well as emotion-related impulsivity, will predict the transition from suicidal thinking to suicidal behavior over time. Third, we hypothesize that short sleep duration will precede within-person increases in suicidal ideation as well as increased odds of suicidal behavior among those reporting suicidal thoughts. METHODS: The desired sample size is 130 adults with past-week suicidal thoughts or behaviors who are receiving inpatient psychiatric treatment. Participants will complete a battery of measures while on the inpatient unit to assess negative affective experiences, emotion-related impulsivity, inhibitory control, typical sleep patterns, and relevant covariates. After discharge from inpatient care, participants will complete 4 weeks of signal-contingent ecological momentary assessment surveys, as well as mobile behavioral measures of inhibitory control, while wearing an actigraphy device that will gather objective data on sleep. Participants will complete interviews regarding suicidal thoughts and behaviors at 4 and 8 weeks after discharge. RESULTS: The study was funded by the National Institutes of Health in November 2020. Recruitment began in April 2021. Data analysis will begin after completion of data collection. CONCLUSIONS: This study will elucidate how affective, cognitive, and physiological risk factors contribute (or do not contribute) to within-person fluctuations in suicide risk in daily life, with important implications for extant theories of suicide. Of import, the examined risk factors are all modifiable; thus, the results will inform identification of key targets for just-in-time, flexible, personalized, digital interventions that can be used to decrease emotional distress and prevent suicide among those at highest risk.
