RESUMEN
Continuous-time modeling using differential equations is a promising technique to model change processes with longitudinal data. Among ways to fit this model, the Latent Differential Structural Equation Modeling (LDSEM) approach defines latent derivative variables within a structural equation modeling (SEM) framework, thereby allowing researchers to leverage advantages of the SEM framework for model building, estimation, inference, and comparison purposes. Still, a few issues remain unresolved, including performance of multilevel variations of the LDSEM under short time lengths (e.g., 14 time points), particularly when coupled multivariate processes and time-varying covariates are involved. Additionally, the possibility of using Bayesian estimation to facilitate the estimation of multilevel LDSEM (M-LDSEM) models with complex and higher-dimensional random effect structures has not been investigated. We present a series of Monte Carlo simulations to evaluate three possible approaches to fitting M-LDSEM, including: frequentist single-level and two-level robust estimators and Bayesian two-level estimator. Our findings suggested that the Bayesian approach outperformed other frequentist approaches. The effects of time-varying covariates are well recovered, and coupling parameters are the least biased especially using higher-order derivative information with the Bayesian estimator. Finally, an empirical example is provided to show the applicability of the approach.
RESUMEN
The current study examined associations between marital quality, loneliness, and sleep within a nationally representative sample of older adults who participated in Wave 2 of the National Social Life, Health, and Aging Project (NSHAP). Participants (N = 559) had a spouse or partner and completed a novel sleep module that included subjective (i.e., insomnia symptoms) and objective (i.e., wake after sleep onset;WASO) markers of sleep. Upon controlling for demographics and markers of mental and physical health, a distinct pattern of findings emerged for subjective versus objective markers of sleep. Regarding subjective sleep, older adults who experienced greater loneliness reported more insomnia symptoms, but only when spousal emotional support was low-moderate. Regarding objective sleep, older adults who reported more affectionate touch from their spouse experienced less WASO. Collectively, these findings identify specific aspects of marital quality that may have unique implications for partnered older adults' subjective and objective sleep quality.

OBJECTIVE: Social stress-loneliness, isolation, and low relationship quality-increase risks for aging-related diseases. However, the ways in which they intersect to undermine healthy aging remain poorly understood. We utilized latent class analysis to identify groups of older adults based on their social stress in both the United States and Mexico. Thereafter, we examined their cross-sectional associations with markers of functional and biological aging. METHOD: Participants in the Health and Retirement Study (HRS, N = 8,316) and Mexican Health and Aging Study (MHAS, N = 15,001) reported their loneliness, isolation (i.e., living alone), and relationship quality with spouse, children, and friends. Outcomes included C-reactive protein (CRP), functional limitations, self-rated health, comorbidities, gait speed, and grip strength. Models controlled for demographics, health behaviors, and body mass index (BMI). RESULTS: In both countries, five classes emerged, a Supported group and four with elevated social stress: (1) Strained, (2) Isolated, (3) Spousal Ambivalence, and (4) Unhappily Married. Compared to the others, Strained participants in both samples had greater functional limitations, poorer self-rated health, and more comorbidities, as well as slower gait in HRS and weaker grip in MHAS. Generally, Supported participants fared better than the other groups. In HRS, CRP levels differed between the Strained group and others, but these associations were explained by health behaviors and BMI. CONCLUSIONS: Older adults in both countries with strained relationships fared worst in their aging-related outcomes, revealing new insights about the links between toxic social stress and unhealthy aging.
RESUMEN
The current study included an examination of social factors that mitigate or exacerbate insomnia symptoms among older adults who are married or living with a partner. We first examined the unique effects of spousal support and strain on insomnia symptoms and then evaluated the degree to which extramarital social factors (e.g., friend support) moderated spousal influences. Data came from Waves 2 and 3 of the National Social Life, Health, and Aging Project. Our sample consisted of 495 participants who were either married or cohabitating with a partner (M age in years = 69.84, SD = 8.08). Spousal strain-but not support-predicted higher insomnia symptoms 5 years later. Spousal influences on sleep, however, were moderated by extramarital factors in nuanced ways. Findings highlight the importance of taking into account older adults' wider social context when examining the ways in which sleep is sensitive to positive and negative aspects of marital quality.

Marital discord fuels depression, according to decades of research. Most prior studies in this area have focused on macro-longitudinal change in depression over the course of years, and on global ratings of marital satisfaction. Less work has examined fluctuations in depressed mood and marital discord in daily life, and none has investigated associations of short-term patterns with longer-term depressed mood and marital outcomes. Using data from participants in the Midlife in the U.S. (MIDUS) project, the current study examined daily associations between marital discord and depressed mood, as well as their links to concurrent and prospective patterns of past-month depressed mood and marital risk. Results showed that, on average, depressed mood rose on days when individuals had an argument or tension with their spouse (i.e., marital discord). More frequent daily marital discord was also associated with greater past-month depressed mood and marital risk, above and beyond prior levels. Those with larger depressive mood responses to discord in daily life (i.e., greater reactivity) exhibited higher concurrent past-month depressed mood and greater 10-year increases in depressed mood. As the first study to link daily marital patterns to concurrent and prospective changes in depressed mood and marital outcomes, this investigation uncovered two novel processes-daily marital discord and depressive reactivity-as important for understanding long-term patterns of marital risk and depression.
RESUMEN
OBJECTIVES: We examined links between marital quality and loneliness among aging veterans and explored whether veterans' PTSD symptom severity moderated these associations. METHODS: Data came from 269 Vietnam-Era combat veterans who had a spouse/partner (M age = 60.50). Utilizing two waves of data spanning six years, we estimated multiple regression models that included positive and negative marital quality, PTSD symptom severity, and loneliness in 2010 as predictors of loneliness in 2016. RESULTS: Facets of positive (but not negative) marital quality were associated with veterans' loneliness. Companionship - spousal affection and understanding - was associated with lower subsequent loneliness among veterans with low/moderate - but not high - PTSD symptom severity. Conversely, sociability - the degree to which one's marriage promotes socializing with others - was associated with lower subsequent loneliness regardless of PTSD symptom severity. CONCLUSIONS: Companionship and sociability were each associated with veterans' subsequent loneliness. Whereas benefits of companionship were attenuated at higher levels of PTSD symptom severity, benefits of sociability were not. CLINICAL IMPLICATIONS: For veterans with higher PTSD symptoms, recommending mental health treatment to decrease symptom severity may help them to reap the benefits of close/intimate relationships. However, bolstering veterans' social participation more broadly may provide an additional means of reducing their loneliness.
RESUMEN
BACKGROUND: Despite increased availability of take-home naloxone, many people who use opioids do so in unprotected contexts, with no other person who might administer naloxone present, increasing the likelihood that an overdose will result in death. Thus, there is a social nature to being "protected" from overdose mortality, which highlights the importance of identifying background factors that promote access to protective social networks among people who use opioids. METHODS: We used respondent-driven sampling to recruit adults residing in New York City who reported recent (past 3-day) nonmedical opioid use (n = 575). Participants completed a baseline assessment that included past 30-day measures of substance use, overdose experiences, and number of "protected" opioid use events, defined as involving naloxone and the presence of another person who could administer it, as well as measures of network characteristics and social support. We used modified Poisson regression with robust variance to estimate unadjusted and adjusted prevalence ratios (PRs) and 95% confidence intervals (CIs). RESULTS: 66% of participants had ever been trained to administer naloxone, 18% had used it in the past three months, and 32% had experienced a recent overdose (past 30 days). During recent opioid use events, 64% reported never having naloxone and a person to administer present. This was more common among those: aged ≥ 50 years (PR: 1.18 (CI 1.03, 1.34); who identified as non-Hispanic Black (PR: 1.27 (CI 1.05, 1.53); experienced higher levels of stigma consciousness (PR: 1.13 (CI 1.00, 1.28); and with small social networks (< 5 persons) (APR: 1.14 (CI 0.98, 1.31). Having a recent overdose experience was associated with severe opioid use disorder (PR: 2.45 (CI 1.49, 4.04), suicidality (PR: 1.72 (CI 1.19, 2.49), depression (PR: 1.54 (CI 1.20, 1.98) and positive urinalysis result for benzodiazepines (PR: 1.56 (CI 1.23, 1.96), but not with network size. CONCLUSIONS: Results show considerable gaps in naloxone protection among people who use opioids, with more vulnerable and historically disadvantaged subpopulations less likely to be protected. Larger social networks of people who use opioids may be an important resource to curtail overdose mortality, but more effort is needed to harness the protective aspects of social networks.

Deployment requires considerable preparation for military families and changes to these plans may create notable stress. The current study leveraged data from a sample of military couples who experienced the cancellation of an overseas deployment to learn more about their experiences as they adjusted to this change. Guided by family stress and anticipatory stress perspectives, we analyzed qualitative data from 28 service members and their significant others (i.e., spouses or cohabitating partners) to understand their overall reactions to the deployment cancellation. We identified three overall reactions (positive, negative, and ambivalent) that were based on participants' appraisals of-and preparations for-deployment, as well as ambiguity about family roles and relationships. Further, participants across groups experienced uncertainty about whether or not the deployment would occur, and altered timelines for other life events. Together, our findings highlight the post-cancellation period as a significant time of stress and transition for military families. However, our findings also signify the need to help all military families cope with uncertainty about when or if deployments will occur given that the military's priorities are often in flux. We therefore describe coping efforts that may be particularly adaptive for families to engage in as they prepare for uncertain, anticipated stressors.
La comisión militar exige una preparación considerable para las familias de militares, y los cambios en estos planes pueden generar bastante estrés. En el presente estudio se utilizaron datos de una muestra de parejas de militares a quienes se les suspendió una comisión fuera del país para averiguar más acerca de sus experiencias mientras se adaptaban a este cambio. Guiados por las perspectivas de estrés familiar y de estrés anticipatorio, analizamos datos cualitativos de 28 miembros del servicio militar y sus parejas (p. ej.: cónyuges o concubinos) para comprender sus reacciones generales a la suspensión de la comisión militar. Identificamos tres reacciones generales (positiva, negativa y ambivalente) que se basaron en las apreciaciones de la comisión y en los preparativos para esta que hicieron los participantes, así como en la ambigüedad acerca de los roles y las relaciones familiares. Además, los participantes de los distintos grupos sintieron incertidumbre acerca de si se produciría o no la comisión y cambiaron programas por otros acontecimientos de la vida. Juntos, nuestros resultados destacan el periodo posterior a la suspensión como un momento de estrés considerable y de transición para las familias de militares. Sin embargo, nuestros resultados también indican la necesidad de ayudar a todas las familias de militares a afrontar la incertidumbre acerca de cuándo ocurrirán las comisiones o de si estas ocurrirán, dado que las prioridades de los militares generalmente cambian constantemente. Por lo tanto, describimos los esfuerzos de afrontamiento que pueden ser particularmente adaptables para las familias mientras se preparan para factores desencadenantes de estrés anticipados e inciertos.

Although the marital relationship is often the primary source of emotional support in adulthood, sole reliance on the spouse to discuss health-related issues may be harmful to the well-being of both partners. The first aim of this study was to examine whether declines in health during later life would be associated with poorer psychological well-being in self and partner. We further investigated whether declining health would have a stronger impact on own and partner psychological well-being in the absence of non-spousal health confidants. Longitudinal actor-partner interdependence models (APIMs) were used to test both hypotheses with dyadic data from Wave 2 (2010-2011) and Wave 3 (2015-2016) of the National Social Life, Health, and Aging Project (NSHAP). Contrary to prediction, increased anxiety following spousal declines in gait speed and cognitive function occurred for those whose spouse did (rather than did not) have additional health confidants. A much fuller understanding is needed in regard to whether close relationships provide resources or present unwanted complications to dyadic coping, and the processes by which effects occur.
RESUMEN
It is projected that by 2020 there will be 8.7 million veterans over the age of 65 years, more than half (64%) of whom served during the Vietnam War. The effects of military service on mental health and well-being may be more pronounced later in life among those who served in Vietnam than prior cohorts of veterans. Many veterans confront and rework their wartime memories later in life in an attempt to find meaning and coherence, engaging in a process referred to as Later-Adulthood Trauma Reengagement (LATR). LATR often occurs in the context of other stressors that are a normative part of aging, such as role transitions (e.g., retirement), declines in physical health, and the death of close others (e.g., spouses), perhaps because these events trigger reminiscence. Importantly, LATR may result in either positive (e.g., acceptance) or negative (e.g., distress) psychological outcomes. It has been suggested that the presence of social/environmental resources, including socioemotional support, may aid veterans in successfully navigating LATR. We, therefore, review relevant areas of research to delineate the role that various layers of social context may play in -helping - or hindering - aging Vietnam veterans as they navigate LATR in the context of normative late-life stressors. We conclude by offering fruitful directions for future research and applied implications for intervention efforts.

BACKGROUND: Existing literature about the psychological side effects of hormonal contraception (HC) is limited. The goal of this study is to better characterize patients' subjective experiences with HC, its side effects, and contraception counseling. METHODS: This is a cross-sectional, survey-based study using a convenience sample of patients who had used HC at some point in their lives. Recruitment occurred from June 2021-February 2022. RESULTS: Of the 188 responses included in the analysis, 43.6% reported experiencing mood changes as a side effect of HC at some point in their lives. The most common reason participants cited for discontinuing or switching contraception methods was side effects (48.3%). Participants with a history of psychiatric illness were significantly more likely to report mood changes as a side effect of their HC (61.2%) compared to participants with no history of psychiatric illness (29.5%). Among patients with a history of psychiatric illness, 38.8% responded that their psychiatric symptoms worsened with HC while only 11.2% responded that their symptoms improved with HC. The majority (83%) of participants responded that their provider never mentioned the possibility of psychological side effects during contraception counseling. If/when they experienced side effects associated with their HC, 22.7% of participants disagreed that their provider adequately addressed their concerns. CONCLUSION: These findings suggest that mood changes may be among the most common perceived side effects of HC and speak to a disconnect between patients and providers when it comes to discussing the possibility of psychological side effects with HC.
RESUMEN
INTRODUCTION: Recent findings support the provision of meditation-based interventions (MBIs) in primary care. However, the acceptability of MBI among patients prescribed medications for opioid use disorder (eg, buprenorphine) in primary care remains unclear. This study assessed experiences and preferences for adopting MBI among patients prescribed buprenorphine in office-based opioid treatment (OBOT). METHODS: This 23-item, semistructured cross-sectional survey was administered by study staff to patients enrolled in OBOT (N = 72) and consisted of demographic and clinical characteristics, perceptions, experiences with MBI, and preferred strategies to access MBI to support their treatment on buprenorphine. RESULTS: Most participants reported practicing at least 1 category of MBI (90.3%) on at least a daily (39.6%) or weekly (41.7%) basis including (1) spiritual meditation (eg, centering prayer; 67.7%); (2) nonmantra meditation (eg, comfortable posture; 61.3%); (3) mindfulness meditation (eg, mindfulness-based stress reduction; 54.8%); and (4) mantra meditation (eg, transcendental meditation; 29.0%). Interest in MBI was motivated by improving one's general health and well-being (73.4%), treatment outcomes with medications for OUD (eg, buprenorphine; 60.9%), and relationships with others (60.9%). Perceived clinical benefits of MBI included reduced anxiety or depression symptoms (70.3%), pain (62.5%), illicit substance or alcohol use (60.9%), cravings for illicit substances (57.8%), and opioid-related withdrawal symptoms (51.6%). CONCLUSIONS: Findings from this study indicate high acceptability for adopting MBI among patients prescribed buprenorphine in OBOT. Further research is needed to assess the efficacy of MBI to improve clinical outcomes among patients initiating buprenorphine in OBOT.

Objective: The timeline followback (TLFB) interview is the gold standard for the quantitative assessment of alcohol use. However, self-reported "drinks" can vary in alcohol content. If this variability is not accounted for, it can compromise the reliability and validity of TLFB data. To improve the precision of the TLFB data, we developed a detailed standard operating procedure (SOP) to calculate standard drinks more accurately from participant reports. Method: For the new SOP, the volume and alcohol content by volume (ABV) of distinct types of alcoholic beverages were determined based on product websites and other reliable sources. Recipes for specific cocktails were constructed based on recipes from bartending education websites. One standard drink was defined as 0.6 oz (14 g) of absolute alcohol. Standard drink totals were contrasted for the new SOP approach and the standard procedure, which generally assumed that one self-reported drink was equivalent to one standard drink. Results: Relative to the standard TLFB procedure, higher numbers of standard drinks were reported after implementing the TLFB SOP. Conclusions: Variability in procedures for conversion of self-reported alcohol consumption to standard drinks can confound the interpretation of TLFB data. The use and reporting of a detailed SOP can significantly reduce the potential for such inconsistencies. Detailed and consistent procedures for calculation of standard drinks can enhance the quality of TLFB drinking data.
RESUMEN
Mitigating the substantial public health impact of concussion is a particularly difficult challenge. This is partly because concussion is a highly prevalent condition, and diagnosis is predominantly symptom-based. Much of contemporary concussion management relies on symptom interpretation and accurate reporting by patients. These types of reports may be influenced by a variety of factors for each individual, such as preexisting mental health conditions, headache disorders, and sleep conditions, among other factors. This can all be contributory to non-specific and potentially misleading clinical manifestations in the aftermath of a concussion. This review aimed to conduct an examination of the existing literature on emerging approaches for objectively evaluating potential concussion, as well as to highlight current gaps in understanding where further research is necessary. Objective assessments of visual and ocular motor concussion symptoms, specialized imaging techniques, and tissue-based concentrations of specific biomarkers have all shown promise for specifically characterizing diffuse brain injuries, and will be important to the future of concussion diagnosis and management. The consolidation of these approaches into a comprehensive examination progression will be the next horizon for increased precision in concussion diagnosis and treatment.
RESUMEN
BACKGROUND: Mobile health (mHealth) tools are used to collect data on patient-reported outcomes (PROs) and facilitate the assessment of patients' self-management behaviors outside the clinic environment. Despite the high availability of mHealth diabetes tools, there is a lack of understanding regarding the underlying reasons why these mHealth PRO tools succeed or fail in terms of changing patients' self-management behaviors. OBJECTIVE: This study aims to identify the factors that drive engagement with an mHealth PRO tool and facilitate patients' adoption of self-management behaviors, as well as elicit suggestions for improvement. METHODS: This qualitative study was conducted within the context of a randomized controlled trial designed to evaluate the efficacy of an mHealth PRO tool (known as i-Matter) versus usual care regarding reduction in glycated hemoglobin (HbA1c) levels and adherence to self-management behaviors at 12 months among patients with uncontrolled type 2 diabetes. Patients randomized to i-Matter participated in semistructured interviews about their experiences at the 3-, 6-, 9-, and 12-month study visits. A qualitative analysis of the interviews was conducted by 2 experienced qualitative researchers using conventional qualitative content analysis. RESULTS: The sample comprised 71 patients, of whom 67 (94%) completed at least one interview (n=48, 72% female patients; n=25, 37% identified as African American or Black; mean age 56.65 [SD 9.79] years). We identified 4 overarching themes and 6 subthemes. Theme 1 showed that the patients' reasons for engagement with i-Matter were multifactorial. Patients were driven by internal motivating factors that bolstered their engagement and helped them feel accountable for their diabetes (subtheme 1) and external motivating factors that helped to serve as reminders to be consistent with their self-management behaviors (subtheme 2). Theme 2 revealed that the use of i-Matter changed patients' attitudes toward their disease and their health behaviors in 2 ways: patients developed more positive attitudes about their condition and their ability to effectively self-manage it (subtheme 3), and they also developed a better awareness of their current behaviors, which motivated them to adopt healthier lifestyle behaviors (subtheme 4). Theme 3 showed that patients felt more committed to their health as a result of using i-Matter. Theme 4 highlighted the limitations of i-Matter, which included its technical design (subtheme 5) and the need for more resources to support the PRO data collected and shared through the tool (subtheme 6). CONCLUSIONS: This study isolated internal and external factors that prompted patients to change their views about their diabetes, become more engaged with the intervention and their health, and adopt healthy behaviors. These behavioral mechanisms provide important insights to drive future development of mHealth interventions that could lead to sustained behavior change.
RESUMEN
Background: Mobile health (mHealth) tools offer an effective and personalized approach to enhance chronic disease management and may partially offset provider-level barriers to increasing buprenorphine prescribing in primary care. This study assessed the feasibility of integrating a text messaging-based medical management tool (TeMeS) in primary care among patients initiating buprenorphine. Methods: TeMeS messages are categorized per the medical management model, programed in a HIPAA-compliant texting software (Apptoto©), and delivered in a tiered fashion over 8-weeks to patients. This mixed-methods evaluation of TeMeS utilized key stakeholder feedback (patients, physicians, administrators, nursing), text messaging software process measures, thematic analysis of patient participant text message content, and electronic administrative data (eg, appointment adherence, treatment retention) at 2-months. Results: The study team approached 65 patients and n = 14 (21%) were ineligible or declined to participate in the study. Most eligible participants owned a smartphone (90%), responded to at least one text query (88%) over an average of 24 days, and few requested to stop receiving texts (6%). Participant text replies included responses to cognitive behavioral therapy-based queries (13.8%), confirming or rescheduling appointments (6.1%), and insurance, pharmacy, or clinical issues pertaining to buprenorphine dispensation or dosing (2%). Suggestions for design modifications included personalizing message content and adjusting message frequency per patient risk of illicit opioid reuse, use of video-based informational content, and real-time provider and staff support for emergent issues. Conclusion: Our findings highlight the acceptability, feasibility, and high rates of engagement of utilizing text messaging to enhance self-management among patients initiating buprenorphine treatment.
RESUMEN
OBJECTIVES: Seminal research with spouses of chronic pain patients indicates that providing patients with instrumental support can be either costly or beneficial for spouses' well-being. Drawing from the invisible support literature, this study evaluated the extent to which patients' recognition of spouses' support moderated daily and long-term associations between spouses' support provision and negative affect. METHOD: Data came from a sample of spouses (N = 145) of knee osteoarthritis (OA) patients, and the patients themselves. Participants completed a baseline interview, 22 days of daily diaries, and two follow-up interviews 6 and 18 months after baseline. Multilevel models were estimated to test study hypotheses. RESULTS: As expected, support visibility moderated daily and long-term associations between spouses' instrumental support provision and negative affect. Spouses reported elevated levels of negative affect in response to providing patients with extra care and attention, but only when their support was not recognized (i.e., reported) by patients. DISCUSSION: Findings from the current study pinpoint support visibility as a protective factor that may mitigate negative short- and long-term effects of spousal instrumental support provision on spouses' negative affect. Promoting patients' awareness of their spouses' support may offset negative emotional consequences of caregiving in the context of chronic health stressors.

OBJECTIVES: Although the adverse link between rumination and sleep quality is well established, much of the literature neglects the role of social factors. This study examined the role of older adults' perceived social support from spouses and from family/friends in modifying the association between trait rumination and sleep quality. Existing hypotheses suggest that social support may play 3 unique roles, each tested within the current study: (H1) support may act as a protective factor that buffers negative effects of rumination on sleep quality, (H2) support may curtail rumination and, in turn, promote sleep quality, and (H3) rumination may erode support and, in turn, undermine sleep quality. METHOD: Data came from 86 partnered older adults in independent-living or retirement communities (Mage = 75.70 years). We utilized 3 waves of interview data collected annually between 2017 and 2019. The first hypothesis was tested using moderation in multilevel models; the second 2 hypotheses were evaluated with prospective associations using multilevel mediation. RESULTS: Negative effects of high-trait rumination on time-varying sleep quality were attenuated among those who reported high, stable levels of support from their spouses. Perceived family/friend support did not yield the same protective effect. There was no evidence that support preempted, or was eroded by, rumination. DISCUSSION: Perceived spousal support may act as a psychosocial resource that mitigates negative effects of trait rumination on older adults' sleep quality. Interventions aimed at mitigating maladaptive outcomes of rumination on sleep quality for older adults should consider spousal support as a key target.

INTRODUCTION/OBJECTIVES: Despite increasing need, there are large gaps in provision of care for unhealthy alcohol use. Primary care practices have become increasingly important in providing services for unhealthy alcohol use, yet little is known about the reasons patients engage in these services and their views on acceptability of such programs. The purpose of this study was to examine primary care patients' reasons for engagement, experiences with, and acceptability of a primary care practice-based program for treating unhealthy alcohol use. METHODS: This qualitative study was conducted in a primary care practice that was developing a collaborative care model for treating unhealthy alcohol use in primary care. Semi-structured interviews were conducted with 24 primary care patients. Data were analyzed using conventional qualitative content analysis. RESULTS: Findings suggest that patients engaged for both internal (concerns about drinking and health) and external reasons (family or provider concern). Patient experiences in the program were shaped by their affective responses (enjoyable, enlightening), as well as therapeutic benefits (gaining new insights about drinking; staff/provider support). Acceptability was driven by core program elements (medication, therapy, integration) as well as positive impacts on drinking cognition and behavior and flexible, patient-centered approaches. CONCLUSIONS: Offering flexible and comprehensive programs with mutiple elements and both abstinence and moderation goals could also improve patient engagement and views on acceptability. Primary care practices will need to be thoughtful about the resources needed to implement these programs in terms of staffing, training, and program support.

The glutamate receptor-associated protein Homer2 regulates alcohol-induced neuroplasticity within the nucleus accumbens (NAC), but the precise intracellular signaling cascades involved are not known. This study examined the role for NAC metabotropic glutamate receptor (mGluR)-Homer2-phosphatidylinositol 3-kinase (PI3K) signaling in regulating excessive alcohol consumption within the context of the scheduled high alcohol consumption (SHAC) model of binge alcohol drinking. Repeated bouts of binge drinking ( approximately 1.5 g/kg per 30 min) elevated NAC Homer2a/b expression and increased PI3K activity in this region. Virus-mediated knockdown of NAC Homer2b expression attenuated alcohol intake, as did an intra-NAC infusion of the mGluR5 antagonist MPEP [2-methyl-6-(phenylethynyl)pyridine hydrochloride] (0.1-1 microg/side) and the PI3K antagonist wortmannin (50 ng/side), supporting necessary roles for mGluR5/Homer2/PI3K in binge alcohol drinking. Moreover, when compared with wild-type littermates, transgenic mice with an F1128R point mutation in mGluR5 that markedly reduces Homer binding exhibited a 50% reduction in binge alcohol drinking, which was related to reduced NAC basal PI3K activity. Consistent with the hypothesis that mGluR5-Homer-PI3K signaling may be a mechanism governing excessive alcohol intake, the "anti-binge" effects of MPEP and wortmannin were not additive, nor were they observed in the mGluR5(F1128R) transgenic mice. Finally, mice genetically selected for a high versus low SHAC phenotype differed in NAC mGluR, Homer2, and PI3K activity, consistent with the hypothesis that augmented NAC mGluR5-Homer2-PI3K signaling predisposes a high binge alcohol-drinking phenotype. Together, these data point to an important role for NAC mGluR5-Homer2-PI3K signaling in regulating binge-like alcohol consumption that has relevance for our understanding of the neurobiology of alcoholism and its pharmacotherapy.
