Although suicide is complex and heterogeneous, most suicide theories assume that suicidal urges occur primarily in the context of extreme emotional distress. Newer models of suicide based on complex systems theory propose greater heterogeneity in suicidal experiences across individuals and groups, such that some, but not all, suicidal thoughts, urges, and behaviors are associated with extreme negative affect. The present study investigated individual differences in affective states experienced during suicidal urges among 138 adults recruited from the community; 81 (59.1 %) owned handguns and 57 (41.6 %) did not. Participants self-reported their current affect and urge to kill themselves 6 times per day for 28 consecutive days via ecological momentary assessment. Positive and negative affect ratings varied significantly during suicidal urges. The association of positive and negative affect with suicidal urges significantly varied within and between handgun owners and non-owners. Results suggest suicidal urges are characterized by high affective heterogeneity.

Firearm availability is correlated with increased risk of suicide but its link with suicidal ideation remains unclear. Previous studies are limited by retrospective reports and prospective designs with lengthy gaps between assessments that are ill-suited for measuring fluctuations in suicidal ideation. This study used ecological momentary assessment (EMA) to repeatedly assess suicidal ideation in a sample of 138 U.S. adults (81 handgun owners, 57 non-owners). Participants received six EMA prompts per day for 28 consecutive days. Results revealed no group differences in the frequency, maximum amplitude, or variability of suicidal ideation across male and female handgun owners and non-owners. Stability of suicidal ideation significantly differed across groups, however (F(1,132) = 4.5, p = 0.036); male handgun owners had the strongest stability and male non-owners had the weakest stability. Stability of suicidal ideation was significantly lower when participants reported a firearm was nearby as compared to when no firearm was nearby (F(4,17732) = 5.6, p < 0.001). Results suggest firearm availability increases reactivity to the environment, slows recovery from acutely elevated risk states, and may increase vulnerability to sudden shifts to higher risk states characterized by increased probability of suicidal behavior. Although these effects were observed in both handgun owners and non-owners, they disproportionately impact handgun owners because they report being near firearms more often.

Objective: The connections among posttraumatic stress disorder (PTSD), depression, and suicidal ideation are elusive because of an overreliance on cross-sectional studies. In this secondary analysis of pooled data from three clinical trials of 742 military personnel, we examined the dynamic relationships among PTSD, depression, and suicidal ideation severity assessed repeatedly during and after outpatient treatment for PTSD. Methods: We conducted dynamical systems analyses to explore the potential for coordinated change over time in psychotherapy for PTSD. Results: Over the course of psychotherapy, PTSD, depression, and suicidal ideation severity changed in coordinated ways, consistent with an interdependent network. Results of eigenvalue decomposition analysis indicated the dominant change dynamic involved high stability and resistance to change but indicators of cycling were also observed, indicating participants "switched" between states that resisted change and states that promoted change. Depression (B = 0.48, SE = 0.11) and suicidal desire (B = 0.15, SE = 0.01) at a given assessment were associated with greater change in PTSD symptom severity at the next assessment. Suicidal desire (B = 0.001, SE < 0.001) at a given assessment was associated with greater change in depression symptom severity at the next assessment. Neither PTSD (B = -0.004, SE = 0.007) nor depression symptom severity (B = 0.000, SE = 0.001) was associated with subsequent change in suicidal ideation severity. Conclusions: In a sample of treatment-seeking military personnel with PTSD, change in suicidal ideation and depression may precede change in PTSD symptoms but change in suicidal ideation was not preceded by change in PTSD or depression symptoms.

Tracy and Robins (Psychological Inquiry, 15(2), 103–125, 2004) theorized that there are two facets of pride: authentic (e.g., “accomplished”) and hubristic (e.g., “arrogant”). While these facets are assumed to function simultaneously over time, it remains unclear whether they differ by gender, given that pride is associated with various social behaviors (Magee Journal of Happiness Studies, 16(5), 1091–1115, 2015; Yeung Shen Journal of Organizational Behavior, 40(6), 605–624, 2019). In this study, we recruited 118 U.S. college students (54.2

Common ways to test associations between two repeatedly measured constructs have two primary limitations. Studies often report the average effects and ignore the heterogeneity. Independently interpreted autoregression and cross-lagged coefficients (i.e. local effects) may not match the holistic dynamic patterns (i.e. considering all coefficients simultaneously). Our paper aims to address the limitations by introducing vector plots to visualize holistic person-specific dynamic patterns. We utilized a case example of 14-day daily diary data of diabetes self-efficacy and self-care from 200 emerging adults with type 1 diabetes. A dynamic structural equation model was used to generate person-specific coefficients. Vector plots and eigenvalues were generated to visualize person-specific holistic patterns. We found heterogeneity in both local and holistic dynamic patterns. Most participants (N = 178) had mismatching local and holistic patterns. Our study provided important evidence that failing to capture person-specific holistic dynamic patterns might result in incomplete interpretations of dynamic associations.

INTRODUCTION:Diabetes-specific family conflict is a risk factor for diabetes indicators (e.g., higher hemoglobin A1c (HbA1c), lower adherence), but little longitudinal data are available to understand associations across time. To better inform targets and timing of interventions, we examined (a) whether fluctuations in conflict covary with diabetes indicators within adolescents across time; (b) whether reciprocal associations exist; and (c) whether aspects of the parent-adolescent relationship (e.g., parental acceptance) buffer associations across time. METHOD:Adolescents (N = 235, ages 11.5-15.5 at baseline, 53.6% female) completed measures of diabetes-related conflict with mothers and with fathers (separately), parental acceptance, and adherence every 6 months across 1 year (three time points). HbA1c was obtained from medical records. Data were collected in 2009. RESULTS:Bivariate between-person correlations indicated that at each time point, adolescents who reported more conflict with mothers and fathers also had higher HbA1c and lower adherence. Within-person correlations (fluctuations across three time points) indicated that fluctuations in conflict with mothers were associated with fluctuations in HbA1c but not adherence. Actor-partner multilevel models indicated that fluctuations in family conflict at each time point were not associated with future diabetes indicators. Parental acceptance did not moderate associations of family conflict and diabetes indicators. DISCUSSION:While findings corroborate extant literature noting that adolescents with high average diabetes-specific family conflict may benefit from interventions designed to reduce conflict, conflict at one time point may not be predictive of future diabetes indicators.

Objective: The present study prospectively examined dynamic associations among sleep, emotion dysregulation, and desire to live during the perinatal transition, as it was theorized that these factors may contribute to the emergence of postpartum suicide risk. Method: Ninety-four women (M-age = 29.2 years; 23.4% Latina) wore wrist actigraphs and completed twice daily surveys for 7 days during the third trimester of pregnancy, 6 weeks postpartum, and 4 months postpartum. Multilevel, change-as-outcome models were built to examine changes in attractor dynamics among sleep, emotion dysregulation, and desire to live, as well as if sleep-emotion dysregulation dynamics differed based on participants' desires to live. Results: From pregnancy to 6 weeks postpartum, emotion dysregulation (B = -0.09, p = .032) and desire to live (B = -0.16, p < .001) exhibited more stable temporal patterns around higher emotion dysregulation and lower desire to live. Compared to women who reported consistently high desires to live, those who experienced fluctuations in their desires to live exhibited lower, more stable sleep efficiency during pregnancy (B = -0.90, p < .001). At 4 months postpartum, those with fluctuating desires to live exhibited a coupling dynamic whereby low sleep efficiency predicted increases in emotion dysregulation (B = -0.16, p = .020). Conclusions: This study was the first to examine nonlinear dynamics among risk factors for postpartum suicide, which may be evident as early as pregnancy and 6 weeks postpartum. Sleep health, in particular, warrants further exploration as a key susceptibility factor in the emergence of postpartum suicide risk.

BACKGROUND:Older adults with type 1 diabetes (T1D) are increasingly turning to care partners (CPs) as resources to support their diabetes management. With the rise in diabetes technologies, such as continuous glucose monitoring (CGM), there is great potential for CGM data sharing to increase CP involvement in a way that improves persons with diabetes' glucose management and reduces distress. OBJECTIVE:The specific aims of this paper are to (1) evaluate the feasibility, usability, and acceptability of the Share plus intervention compared to the CGM Follow app plus diabetes self-management education and support; (2) evaluate the effect of the Share plus intervention on time-in-range (TIR; primary outcome) and diabetes distress (secondary outcome); and (3) explore differences between groups in person with diabetes and CP dyadic appraisal and coping, quality of life, diabetes self-care, and CP burden at 12 and 24 weeks and associations of dyadic variables on outcomes. METHODS:This is a protocol for a feasibility, pilot randomized controlled trial. Older adults with T1D and their CP (N=80 dyads) will be randomized 1:1 to the Share plus intervention or Follow app plus diabetes self-management education. The trial will include a 12-week active intervention to determine the change in primary (TIR) and secondary (diabetes distress) outcomes, followed by a 12-week, observation-only phase to examine maintenance effects. The evaluation is guided by the Dyadic Coping Model. Patient-level effectiveness outcomes (TIR, hemoglobin A1c [HbA1c], diabetes distress, diabetes appraisal, coping, quality of life, diabetes self-care behaviors, and CP burden) will be assessed, using patient-reported outcomes measures and a home HbA1c test kit. Patient- and CP-level acceptability and feasibility will be assessed using surveys and interviews. Quantitative feasibility, acceptability, and usability data will be described using frequencies and percentages. Acceptability will be summarized based on Likert questions and open-ended questions. Usability will be examined separately for the intervention and control groups based on the System Usability Scale, with a study benchmark of ≥68 indicating good usability. TIR will be computed based on 2 weeks' worth of data at baseline (prior to intervention) and 2 weeks each after the intervention (week 12) and at follow-up (week 24). RESULTS:Recruitment started in August 2023 and enrollment began in November 2023. To date, 24 participants have been enrolled in this study. We expect to conclude this study in March 2026 and expect to disseminate results in March 2026. CONCLUSIONS:To our knowledge, this will be the first pilot randomized controlled trial to evaluate both feasibility and effectiveness outcomes for the web-based, platform-delivered Share plus intervention for older adults with T1D and their CP. This research has implications for CGM data sharing in other age groups with T1D and type 2 diabetes. TRIAL REGISTRATION:ClinicalTrials.gov NCT05937321; https://clinicaltrials.gov/study/NCT05937321.

In this study, we investigate using passive data, specifically heart rate and actigraphy, for individuals with binge-type eating disorders such as bulimia nervosa (BN) and binge-eating disorder (BED). By applying dynamical-system theory and incorporating advancements in technology-based health care, we explored the relationship between passive data patterns as potential indicators of binge-eating episodes. Over 30 days, 1,019 participants with BN or BED symptoms used the Recovery Record app on iPhone and Apple Watches for real-time eating-behavior logging. Apple Watches simultaneously recorded heart rate and actigraphy. Results show no marked difference in heart and step averages 2 hr before a binge versus a control period. However, significant momentum and stability differences emerged when examining the changing dynamics leading up to a binge event. These findings suggest that the stability of step, rather than their average value, may serve as a detectable indicator of approaching binge events.

ObjectiveInterventions for emerging adults (EAs) with type 1 diabetes (T1D) focus on goal setting, but little is known about how goal achievement relates to intervention outcomes. We examined how goals change, how goal achievement relates to diabetes outcomes, and identified barriers and facilitators to goal achievement.MethodEAs with T1D (N=29, M age=21.6 years, 57% female) were coached monthly to set a behavioral goal across a 3-month feasibility trial. Coaching notes were qualitatively coded regarding type, complexity, and changes in goals. Goal achievement was measured via daily responses to texts. HbA1c, self-efficacy, diabetes distress, and self-care were assessed pre- and post-intervention.ResultsEAs frequently set food goals (79%) in combination with other goals. EAs overwhelmingly changed their goals (90%), with most increasing goal complexity. Goal achievement was high (79% of days) and not affected by goal change or goal complexity. Goal achievement was associated with increases in self-efficacy and self-care across time. Qualitative themes revealed that aspects of self-regulation and social-regulation were important for goal achievement.ConclusionMeeting daily diabetes goals may enhance self-efficacy and self-care for diabetes.Practice ImplicationsAssisting EAs to reduce self-regulation challenges and enhance social support for goals may lead to better diabetes outcomes.

Purpose: Depressive symptoms during the perinatal period have broad and enduring health implications for birthing parents and their offspring. Rising prevalence rates of perinatal depression highlight the need for research examining factors influencing depressive symptoms during pregnancy, and trajectories during the early postnatal period. Grounded in bioecological systems theory, this longitudinal multimethod study examined whether prenatal bioecological factors predict depressive symptoms from pregnancy to 36 months postpartum. Methods: Participants were 162 pregnant individuals, oversampled for high emotion dysregulation, who completed a life stress interview and physiological assessment during the 3rd trimester and a self-report measure of depression at five time-points (3rd trimester, within 48 h of birth, 7, 18, and 36 months postpartum). Multilevel models were used to test study aims. Results: Participants exhibited the highest levels of depressive symptoms at 3rd trimester, and substantial variability in depressive symptom trajectories over time. Lower resting respiratory sinus arrhythmia (RSA), an index of parasympathetic nervous system functioning, in the 3rd trimester was associated with higher concurrent depressive symptoms. Higher levels of stress related to partner relationships, finances, and health were concurrently associated with more depressive symptoms during pregnancy and decreases in depressive symptoms over time. Specifically, depressive symptoms decreased only for individuals who reported high levels of stress during pregnancy. Limitations: Although grounded in bioecological systems theory, this study did not assess the macrosystem. Conclusions: Results of this study underscore the importance of multilevel predictors of perinatal health and highlights potential targets for preventing depression and promoting well-being during the perinatal transition.

Background Executive functioning (EF) predicts better Type 1 diabetes (T1D) management in the high-risk years after high school, but the daily self-regulation processes involved are unclear. Purpose To examine whether EF is associated with daily self-regulation that minimizes one’s exposure or buffers adverse reactions to daily diabetes problems, and to determine whether these patterns become stronger during the transition out of high school. Methods A measurement burst design with convenience sampling was used. Seniors in high school with T1D (N = 207; 66% female) completed self-report (i.e., Behavioral Rating Inventory of Executive Functioning) and performance measures of EF (i.e., Delis-Kaplan Executive Function System). A 14-day daily diary assessing self-regulation failures, diabetes problems, affect, and indicators of diabetes management was completed at baseline and 1 year later. Results Correlations and multilevel modeling were conducted. Lower self-reported EF problems were associated with lower average levels of daily self-regulation failures, and these variables were associated with fewer daily diabetes problems. In contrast, better EF performance was unrelated to average daily self-regulation failures, and was unexpectedly associated with more frequent diabetes problems in year 2. Equally across years, on days participants reported lower than their average levels of daily self-regulation failures, they had fewer diabetes problems, regardless of EF. On days with lower than average diabetes problems, participants reported better diabetes management indicators. EF generally did not buffer daily associations in either year. Conclusions Regardless of EF, promoting daily self-regulation may prevent diabetes problems and promote T1D management in daily life at this high-risk transitional time.

Developmental researchers commonly utilize longitudinal data to decompose reciprocal and dynamic associations between repeatedly measured constructs to better understand the temporal precedence between constructs. Although the cross-lagged panel model (CLPM) is commonly used in developmental research, it has been criticized for its potential to produce biased estimates due to the fact of ignoring the trait-like, time-invariant nature of stability in constructs across people and aggregating the between- and within-person effects together as a single estimate. Recently, a growing set of alternatives have emerged, but the estimates across CLPM and alternatives have rarely been compared in developmental research. The primary purpose of this article is to (a) provide a three-component framework to help developmental researchers to select and specify the most appropriate model, and (b) illustrate how models differ in estimates with an empirical example investigating the reciprocal associations between internalizing and externalizing problems in school-aged children. Methods: We specified CLPM, Random-Intercept Cross-lagged Panel Model (RI-CLPM), Latent Curve Model with Structured Residuals (LCM-SR), Latent Change Score (LCS), and a Random-Mean LCS using four waves of data from ECLS-K: 2011 (N = 8779). Results: The CLPM provided the most evidence of significant cross-lagged paths but the poorest fit to the data compared to other models. Alternative models had excellent fit and found either only negative temporal precedence from internalizing to externalizing problems or simply no evidence of prospective within-person relations between internalizing and externalizing problems.

Diabetes-related family conflict is widely regarded as a risk factor for diabetes outcomes, yet it has not been examined on a daily basis. Parental acceptance may attenuate the degree to which family conflict is associated with diabetes outcomes. The present study examined (a) within- and between-person fluctuations in diabetes problems and family conflict, (b) within- and between-person links between conflict and blood glucose (BG) mean, and (c) whether parental acceptance moderated these associations. One hundred eighty adolescents (M-age = 12.92 years) with T1D completed a 14-day diary measuring diabetes problems, conflict with mother, conflict with father, and parental acceptance at the end of each day. Daily average BG values were calculated from glucometer readings. Higher diabetes problems on average across the 14-day diary were associated with more average conflict with mothers (between-person), but daily fluctuations in the number of diabetes problems were not related to daily conflict (within-person). Adolescents with higher conflict with mothers and fathers on average across the 14 days had higher BG means (between-person); however, on days when adolescents reported higher conflict, they had greater risk for low BG (within-person). Daily parental acceptance did not moderate associations between problems and conflict nor conflict and BG mean. This study was the first to examine daily diabetes-specific conflict with mothers and fathers during adolescence. The number of diabetes problems did not predict daily conflict. Fluctuations in daily conflict were associated with greater risk for low BG, underscoring the need for future research examining in-the-moment relations among conflict and BG extremes.

Tic disorders are a class of neurodevelopmental disorders characterized by involuntary motor and/or vocal tics. It has been hypothesized that tics function to reduce aversive premonitory urges (i.e., negative reinforcement) and that suppression-based behavioral interventions such as habit reversal training (HRT) and exposure and response prevention (ERP) disrupt this process and facilitate urge reduction through habituation. However, previous findings regarding the negative reinforcement hypothesis and the effect of suppression on the urge-tic relationship have been inconsistent. The present study applied a dynamical systems framework and within-subject time-series autoregressive models to examine the temporal dynamics of urges and tics and assess whether their relationship changes over time. Eleven adults with tic disorders provided continuous urge ratings during separate conditions in which they were instructed to tic freely or to suppress tics. During the free-to-tic conditions, there was considerable heterogeneity across participants in whether and how the urge-tic relationship followed a pattern consistent with the automatic negative reinforcement hypothesis. Further, little evidence for within-session habituation was seen; tic suppression did not result in a reduction in premonitory urges for most participants. Analysis of broader urge change metrics did show significant disruption to the urge pattern during suppression, which has implications for the current biobehavioral model of tics.

The dynamics of parent-infant physiology are essential for understanding how biological substrates of emotion regulation are organized during infancy. Although parent-infant physiological processes are dyadic in nature, research is limited in understanding how one person's physiological responses predict one's own and as well as the other person's responses in the subsequent moment. In this study, we examined mother-infant respiratory sinus arrhythmia (RSA) dynamics during the Still-Face Paradigm (SFP) among 106 mothers (Mage  = 29.54) and their 7-month-old infants (55 males). Given mothers' role in shaping dyadic interactions with their infant, we also tested how mothers' self-reported emotion dysregulation (measured via the Difficulties in Emotion Regulation Scale) associated with these dynamics. Results showed that both mothers' and infants' RSA tended to return to their respective homeostatic points (i.e., exhibited return strength) during each SFP episode, indicating stability in RSA for mother-infant dyads. Significant shifts in mother and infant RSA return strength were observed across SFP episodes, highlighting the role of contextual demands on each individual's physiological dynamics. Mother-infant RSA dynamics varied as a function of maternal self-reported emotion dysregulation. Specifically, RSA levels of infants with more dysregulated mothers had a weaker tendency to return to homeostasis during the Reunion episode and were less affected by their mothers' RSA during the Still-Face and Reunion episodes of the SFP, suggesting a less effective coregulatory influence. Our findings have implications for the intergenerational transmission of emotion dysregulation via mother-infant physiological dynamics.

We examined how global stress and general stressors of daily life relate to emotional well-being and type 1 diabetes (T1D) outcomes and amplify the effects of diabetes stressors in emerging adults. Two-hundred and seven 18-19-year-olds with T1D (duration 8.47 years) completed the Perceived Stress Scale (global stress) and a daily diary assessing daily diabetes and general stressors, positive and negative affect, self-care behaviors, and blood glucose (BG). Multi-level analyses indicated that global stress and within-person daily general and diabetes stressors were associated with more negative and less positive affect. In addition, general stress (between-person) was associated with more negative affect. Global stress amplified the association between daily diabetes stressors and negative affect, with greater affect reactivity to stress for those experiencing higher global stress. Global stress and both within- and between-person diabetes stressors were associated with lower self-care and higher BG. Emerging adults' general stressors in their daily lives relate to poorer well-being beyond the experience of diabetes stressors.

This study examined the heterogeneity in the co-developmental trajectories of reading and math performance (i. e., parallel changes in the initial scores and growth patterns) and identified the number, size and shape of the co -developmental trajectory across elementary and middle schools. In addition, this investigation focused on how an early childhood dysregulation profile (DP; indexed by a high co-occurrence of emotional, behavior, and attention problems) was associated with distinct co-developmental trajectories of reading and math performance. Specifically, we examined whether early childhood DP level can predict (a) membership assignment into each distinct co-development group and (b) variability in initial scores and changes in growth with each distinct co -development group. Participants were 784 academically at-risk students (47 % girls) predominantly from low socioeconomic status families who were recruited in first grade (Mean age = 6.57 years) and followed annually through the final year of middle school (ninth grade). Results revealed two distinct co-developmental trajectories of reading and math performance, including (a) a lower initial reading (higher increasing) and higher initial math (lower increasing) class (85.3 %) and (b) a lower initial math (higher increasing) and higher initial reading (lower increasing) class (14.7 %). Our results provided evidence for the compensatory pattern of co -developmental trajectories, indicating initial lower skills grow at a faster rate than the initial high. Further, early childhood DP was not associated with the membership assignment for these two distinct classes, which means that regardless of children's early DP level, they have equal chances to be assigned to each of the classes. However, children with higher parent and teacher-reported DP in first grade demonstrated lower initial scores and a slower improvement rate in both classes after controlling for kindergarten literacy skills, gender, ethnicity, intelligence, socioeconomic status, and grade retention. Our study findings demonstrated (a) substantial het-erogeneity in the co-developmental trajectories of reading and math performance across elementary and middle school ages; and (b) the importance of promoting self-regulation beginning in early childhood, especially for academically at-risk children in families facing economic challenges.

Firearm carrying is often motivated to provide safety and is correlated with increased anxiety related to elevated perceptions of the world as a dangerous place. No studies have investigated affective states among firearm owners as they occur in their natural environments. This study used ecological momentary assessment (EMA) to examine cognitive-affective states among firearm owners who carry handguns outside their home (n = 35), firearm owners who do not carry (n = 47), and non-firearm owners (n = 62). Participants completed a self-report questionnaire at baseline followed by EMA surveys of mood state with the Positive and Negative Affect Scale (PANAS) 6 times per day for 28 consecutive days. Carry handgun owners reported significantly higher threat perceptions, measured with the negative cognitions about the world subscale of the shortened Posttraumatic Cognitions Inventory (PTCI), than no-carry handgun owners (Mdiff=2.0, 95% CI=0.8-2.0, d=0.45, p = .001) and non-owners (Mdiff=1.8, 95% CI=0.6-2.9, d=0.42, p = .003). Groups did not significantly differ in mean momentary mood ratings assessed via EMA but stability in high-arousal negative arousal was significantly reduced among carry handgun owners (F(2, 150)= 3.7, p = .026). Results suggest firearm owners who carry handguns view the world as especially dangerous, are more likely to experience shifts in anxiety and fear, and take longer to recover from periods of elevated anxiety and fear.
