Disrupted executive cerebro-cerebellar functional connectivity in alcohol use disorder.

BACKGROUND: Alcohol use disorder (AUD) affects 283 million people worldwide and its prevalence is increasing. Despite the role of the cerebellum in executive control and its sensitivity to alcohol, few studies have assessed its involvement in AUD-relevant functional networks. The goal of this study is to compare resting-state functional connectivity (FC) patterns in abstinent adults with a history of AUD and controls (CTL). We hypothesized that group differences in cerebro-cerebellar FC would be present, particularly within the frontoparietal/executive control network (FPN). METHODS: Twenty-eight participants completed a resting-state functional magnetic resonance imaging (rsfMRI) study. CTL participants had no history of AUD, comorbid psychological conditions, or recent heavy drinking and/or drug use. AUD participants had a history of AUD, with sobriety for at least 30 days prior to data collection. Multivariate pattern analysis, an agnostic, whole-brain approach, was used to identify regions with significant differences in FC between groups. Seed-based analyses were then conducted to determine the directionality and extent of these FC differences. Associations between FC strength and executive function were assessed using correlations with Wisconsin Card Sorting Test (WCST) performance. RESULTS: There were significant group differences in FC in nodes of the FPN, ventral attention network, and default mode network. Post hoc analyses predominantly identified FC differences within the cerebro-cerebellar FPN, with AUD showing significantly less FC within the FPN. In AUD, FC strength between FPN clusters identified in the multivariate pattern analysis (MVPA) analysis (Left Crus II, Right Frontal Cortex) was positively associated with performance on the WCST. CONCLUSIONS: Our results show less engagement of the FPN in individuals with AUD than in CTL. FC strength within this network was positively associated with performance on the WCST. These findings suggest that long-term heavy drinking alters cerebro-cerebellar FC, particularly within networks that are involved in executive function.

A Pilot Study of the Adoption and Guardianship Enhanced Support (AGES) Program: Preventing Discontinuity by Walking Alongside Adoptive and Guardianship Families Who are Struggling.

PURPOSE: There is a strong preference for evidence-based child welfare services, however, there are few well-researched programs for families that struggle post-permanence. Following adoption or guardianship, some families experience significant challenges, struggle to find effective programs, and run the risk of family instability. This study described the process used to develop the Adoption and Guardianship Enhanced Support (AGES) intervention and explored: 1) the needs of families participating in the program and 2) how AGES worked with families to address those challenges. METHODS: This descriptive study utilized quantitative structured assessment data and qualitative data from case records to explore the needs of families and provide context for qualitative, in-depth interviews with families regarding their experiences with the AGES program, presented using thematic analysis. RESULTS: Pre-service structured assessments indicated multiple dimensions of parenting strain, with case record reviews and interviews with families providing a nuanced picture of multiple sources of strain, suggesting the project was reaching the intended audience. Record review and interviews demonstrated strong alignment between needs of families and the support provided by AGES workers. Intended analysis of quantitative post-assessment data was not possible, due to lower enrollment and higher staff turnover than expected, as well as study timeframes. DISCUSSION AND CONCLUSION: The approach utilized by AGES workers, one that walked alongside families and provided flexible responses to identified needs, showed promise for adoptive and guardianship families. Replication and additional research are needed to assess the program with a larger sample and more rigorous methods.

Promoting Healthy Relationships in Foster Care-"If I Had Seen What a Healthy Relationship Looks Like, that Would Have Changed My Perspective".

High levels of intimate partner violence among youth and young adults with history in foster care can perpetuate the cycle of violence and abuse. It is therefore important to understand how the experience of growing up in foster care impacts youths' understanding and formation of intimate relationships. This qualitative study centered the perspectives of young adults and investigated what they learned about relationships through interactions with foster caregivers and child welfare professionals. We conducted semi-structured interviews with 27 young adults and used Consensual Qualitative Research methods to identify critical experiences in foster care and formulate strategies for promoting healthy relationships.

Naltrexone engages a brain reward network in the presence of reward-predictive distractor stimuli in males.

The non-selective opioid receptor antagonist, naltrexone is one of the most prescribed medications for treating alcohol and opioid addiction. Despite decades of clinical use, the mechanism(s) by which naltrexone reduces addictive behavior remains unclear. Pharmaco-fMRI studies to date have largely focused on naltrexone's impact on brain and behavioral responses to drug or alcohol cues or on decision-making circuitry. We hypothesized that naltrexone's effects on reward-associated brain regions would associate with reduced attentional bias (AB) to non-drug, reward-conditioned cues. Twenty-three adult males, including heavy and light drinkers, completed a two-session, placebo-controlled, double-blind study testing the effects of acute naltrexone (50 mg) on AB to reward-conditioned cues and neural correlates of such bias measured via fMRI during a reward-driven AB task. While we detected significant AB to reward-conditioned cues, naltrexone did not reduce this bias in all participants. A whole-brain analysis found that naltrexone significantly altered activity in regions associated with visuomotor control regardless of whether a reward-conditioned distractor was present. A region-of-interest analysis of reward-associated areas found that acute naltrexone increased BOLD signal in the striatum and pallidum. Moreover, naltrexone effects in the pallidum and putamen predicted individual reduction in AB to reward-conditioned distractors. These findings suggest that naltrexone's effects on AB primarily reflect not reward processing per se, but rather top-down control of attention. Our results suggest that the therapeutic actions of endogenous opioid blockade may reflect changes in basal ganglia function enabling resistance to distraction by attractive environmental cues, which could explain some variance in naltrexone's therapeutic efficacy.

Investigating the relationship between early life adversity, inflammation and alcohol use.

Early life adversity (ELA) has long-lasting and potentially harmful effects on adult mental and physical health, including a higher likelihood of developing psychiatric conditions such as depression, anxiety and alcohol use disorder (AUD). It has been suggested that inflammation may play a role in linking ELA to the development of AUD. Here, we evaluated a number of predictive factors of high sensitivity C-reactive protein (hsCRP), a key inflammatory marker, and the potential mediating role of hsCRP in the relationship between ELA and alcohol misuse in adulthood. Data was collected from participants who participated in NIAAA screening protocols between January 2013 and December 2019. In this secondary analysis, we first tested, via multiple linear regression, potential predictors of hsCRP levels among adults with AUD (N = 781) and non-AUD (N = 440) individuals. We subsequently conducted mediation analyses to evaluate the potential role of hsCRP in the relationship between early life stress and alcohol use. Regression analysis showed that stress in early life, but not childhood trauma, significantly predicted increased hsCRP levels in adulthood (p < 0.05). Additionally, a greater amount of alcohol drinking, but not a diagnosis of AUD, significantly predicted increased hsCRP levels (p < 0.05). Furthermore, hsCRP mediated the relationship between early life stress and alcohol consumption. Early life stress and heavier alcohol drinking both predicted increased hsCRP levels; however, an AUD diagnosis did not. Elevated inflammation, due to and/or predicted by greater early life stress, may contribute to the development of unhealthy alcohol use in adulthood.

Innovation in Sexuality and Relationship Education in Child Welfare: Shifting Toward a Focus on Ongoing Conversations, Connection, and Consent.

Youth in foster care experience disproportionate rates of abusive relationships, teen pregnancy, and sexually transmitted infections (STIs). Extant research points to the need for interventions at multiple levels of the social ecology, however, there is a lack of evidence to guide the development of coordinated interventions for youth, foster parents, and child welfare professionals. The Texas Foster Youth Health Initiative (TFYHI) convened a multidisciplinary learning community to build a foundation for intervention development. The intentional learning and innovation process engaged several groups of stakeholders: young adults with lived experience (n = 41), foster parents (n = 14), and child welfare professionals (n = 52). Interviews, community listening sessions, and reflection exercises were designed to capture tacit and experiential knowledge and explore challenges and desired outcomes from different perspectives. Based on a thematic analysis of stakeholder perspectives, we identified overarching needs to normalize conversations about sexuality and relationships and shift away from risk-based and stigmatizing approaches. We also identified key strategies for designing coordinated interventions targeting youth, foster parents, and child welfare professionals: (1) Reflect on values about sexuality and relationships. (2) Validate youths' need for connection. (3) Focus on strengthening youth-adult relationships and ongoing conversations. (4) Build healthy relationship skills including communication about consent, condom use, and contraception. (5) Identify teachable moments and model problem solving. (6) Use interactive approaches for sharing health information and empower youth to choose methods that fit their needs.

Racial Differences in the Association Between Alcohol Drinking and Cigarette Smoking: Preliminary Findings From an Alcohol Research Program.

AIMS: Important differences have been shown in alcohol drinking and cigarette smoking prevalence, patterns and consequences among individuals from different racial backgrounds. Alcohol and nicotine are often co-used, and the association between drinking and smoking may differ between racial groups-a question explored in the present study. METHODS: Data from the NIAAA natural history and screening protocols were utilized; non-Hispanic Black and non-Hispanic White individuals were included in the analyses [N = 1692; 65.2% male; 58.3% met criteria for current alcohol use disorder (AUD); 37.8% were current cigarette smokers]. Bivariate associations between assessments related to alcohol drinking and cigarette smoking were examined, and the strength and direction of these associations were compared between the two groups. RESULTS: The sample included 796 Black and 896 White individuals. Black participants had higher frequency (P < 0.0001) and severity (P = 0.007) of AUD, as well as higher frequency (P < 0.0001) of cigarette smoking. Bivariate analyses showed that the expected positive associations between alcohol drinking and cigarette smoking, observed among White individuals, were blunted or absent among Black individuals [age at first cigarette-AUD identification test (AUDIT) score: F(1, 292) = 7.60, P = 0.006; cigarette pack years-AUDIT score: F(1, 1111) = 10.97, P = 0.001]. CONCLUSIONS: Some decoupling in the association between alcohol drinking and cigarette smoking was found among Black compared to White individuals. The sample was drawn from a specific population enrolled in alcohol research protocols, which is a limitation of the present study. These preliminary findings highlight the importance of considering racial/ethnic background in preventive and therapeutic strategies for comorbid alcohol and nicotine use.

ACE-Informed Responses in Central Texas: Findings from a Needs Assessment.

The objectives of this study were to examine: a) adverse childhood experience (ACE) knowledge among healthcare professionals in Central Texas; b) prevalence of screening and patient disclosure of ACEs; c) implementation of ACE-informed response strategies; and d) the relationship between ACE knowledge and familiarity, and implementation of ACE-informed response strategies. A needs assessment was conducted using an online survey that included closed- and open-ended questions. Purposive and snowball sampling were utilized to recruit healthcare providers, with a focus on pediatric and women's healthcare providers. Eighty-five healthcare providers completed the survey. Most respondents were unfamiliar with the ACE study, but 59.6% had attended trainings on the impact of trauma on child health. Respondents screened most frequently for mental illness and drug/alcohol abuse in their practice. The most frequently reported ACE-informed response strategies included identifying strengths and utilizing on-site resources, while broader strategies such as creating an ACE-informed culture within their practice were implemented by less than 10% of respondents. ACE knowledge was correlated with two of the ACE-informed response strategies. Although many healthcare providers still lack familiarity with ACEs, awareness of trauma and its impact on child health may be more common. Given the positive correlation between ACE familiarity and ACE-informed response strategies, it appears more education and resources are needed to engage healthcare providers in responding to ACEs. Specific strategies, such as community-wide trainings, opportunities for provider collaboration and communication, and critical analysis of policies, may cultivate a more ACE-informed and ACE-responsive culture.

Acute depletion of dopamine precursors in the human brain: effects on functional connectivity and alcohol attentional bias.

Individuals who abuse alcohol often show exaggerated attentional bias (AB) towards alcohol-related cues, which is thought to reflect reward conditioning processes. Rodent studies indicate that dopaminergic pathways play a key role in conditioned responses to reward- and alcohol-associated cues. However, investigation of the dopaminergic circuitry mediating this process in humans remains limited. We hypothesized that depletion of central dopamine levels in adult alcohol drinkers would attenuate AB and that these effects would be mediated by altered function in frontolimbic circuitry. Thirty-four male participants (22-38 years, including both social and heavy drinkers) underwent a two-session, placebo-controlled, double-blind dopamine precursor depletion procedure. At each visit, participants consumed either a balanced amino acid (control) beverage or an amino acid beverage lacking dopamine precursors (order counterbalanced), underwent resting-state fMRI, and completed behavioral testing on three AB tasks: an alcohol dot-probe task, an alcohol attentional blink task, and a task measuring AB to a reward-conditioned cue. Dopamine depletion significantly diminished AB in each behavioral task, with larger effects among subjects reporting higher levels of binge drinking. The depletion procedure significantly decreased resting-state functional connectivity among ventral tegmental area, striatum, amygdala, and prefrontal regions. Beverage-related AB decreases were mediated by decreases in functional connectivity between the fronto-insular cortex and striatum and, for alcohol AB only, between anterior cingulate cortex and amygdala. The results support a substantial role for dopamine in AB, and suggest specific dopamine-modulated functional connections between frontal, limbic, striatal, and brainstem regions mediate general reward AB versus alcohol AB.

A neuroimaging investigation into the role of peripheral metabolic biomarkers in the anticipation of reward in alcohol use.

BACKGROUND: The relationship between alcohol use and metabolism has focused on the effects of alcohol use on metabolic factors. Metabolic factors, such as triglycerides, cholesterol, and glucose, have been shown to be associated with increased risk for heavy alcohol consumption and alcohol use disorder (AUD). It's been suggested that changes in metabolic factors may play a role in reward seeking behaviors and pathways. Studies on feeding behavior and obesity revealed the role of triglycerides in neural response to food cues in neurocircuitry regulating reward and feeding behaviors. This study aimed to explore the relationship of peripheral metabolism, alcohol use, and reward processing in individuals that use alcohol. METHODS: Ninety participants from a previously collected dataset were included in the analysis. Participants were treatment seeking, detoxified individuals with AUD and healthy individuals without AUD, with the following metabolic biomarkers: triglyceride, glucose, high- and low-density cholesterol, and HbA1c levels. Participants completed a neuroimaging version of the Monetary Incentive Delay task (MID). RESULTS: Correlations on peripheral metabolic biomarkers, alcohol use, and neural activity during reward anticipation and outcome during the MID task were not significant. Mediation models revealed triglycerides and high-density cholesterol had significant effects on left anterior insula during anticipation of potential monetary loss and this effect was not mediated by alcohol use. CONCLUSION: Limbic recruitment by anticipation of monetary rewards revealed an independent relationship with peripheral metabolism and was not affected by individual differences in alcohol use, despite the effects of alcohol use on metabolic markers and reward processing neural circuitry.

Standing and Responding in Solidarity with Disenfranchised Immigrant Families in the United States: An Ongoing Call for Action.

The status of immigrant families resettled to the United States in the past decade has been fraught with upsurges of governmental policies that have systematically increasing the levels of oppression, violence, and abuses of human rights. The socio-political-economic toll of xenophobic practices on specifically targeted immigrant populations is magnified by the psychological and relational impact they have on individuals, families, and communities. This manuscript is conceptualized as an ongoing call for social action and specific mobilization by mental health professionals in response to the increasing threats to civility and dignity faced by various immigrant communities. The paper is organized in three sections: (a) an overview of the effects of immigration policy on immigrant family experiences; (b) the impact of mental and relational health on immigrant populations; and (c) elaborations of three exemplar community projects designed to support immigrant families. The manuscript concludes with a discussion exploring avenues for promoting a stronger base for solidarity and social action.

Exploring How Trauma Is Addressed in Sexual Education Interventions for Youth: A Scoping Review.

Traumatic experiences are common among adolescents and can negatively affect learning and increase the risk of early pregnancy, parenthood, and sexually transmitted infections. Little is known about how current sexual health interventions address trauma. A scoping review was conducted to gain insight into how trauma is addressed in adolescent sexual health interventions. Peer-reviewed studies from the United States published between 2008 and 2018 describing a sexual health intervention for youth were considered. Studies were analyzed to determine if and how trauma was addressed in the interventions. Out of 169 articles initially screened, 29 met inclusion criteria and 23% (n = 6) addressed trauma. Four interventions addressed trauma in the intervention content, while two studies evaluated trauma in outcome measures. Educators can broaden this reach by developing trauma-informed content that is compatible with existing curricula. Ongoing study is recommended to evaluate the impact of trauma-informed content on the sexual knowledge, attitudes, and behaviors of youth.

Contingency awareness, aging, and the parietal lobe.

Contingency awareness is thought to rely on an intact medial temporal lobe and also appears to be a function of age, as older subjects tend to be less aware. The current investigation used functional magnetic resonance imaging, transcranial direct current stimulation, and eyeblink classical conditioning to study brain processes related to contingency awareness as a function of age. Older adults were significantly less aware of the relationship between the tone-airpuff pairings than younger adults. Greater right parietal functional magnetic resonance imaging activation was associated with higher levels of contingency awareness for younger and older subjects. Cathodal transcranial direct current stimulation over the right parietal lobe led to lower levels of awareness in younger subjects without disrupting conditioned responses. Older adults exhibited hyperactivations in the parietal and medial temporal lobes, despite showing no conditioning deficits. These findings strongly support the idea that the parietal cortex serves as a substrate for contingency awareness and that age-related disruption of this region is sufficient to impair awareness, which may be a manifestation of some form of naturally occurring age-related neglect.

Changes in Hemodynamic Response Function Resulting From Chronic Alcohol Consumption.

BACKGROUND: Functional MRI (fMRI) task-related analyses rely on an estimate of the brain's hemodynamic response function (HRF) to model the brain's response to events. Although changes in the HRF have been found after acute alcohol administration, the effects of heavy chronic alcohol consumption on the HRF have not been explored, and the potential benefits or pitfalls of estimating each individual's HRF on fMRI analyses of chronic alcohol use disorder (AUD) are not known. METHODS: Participants with AUD and controls (CTL) received structural, functional, and vascular scans. During fMRI, participants were cued to tap their fingers, and averaged responses were extracted from the motor cortex. Curve fitting on these HRFs modeled them as a difference between 2 gamma distributions, and the temporal occurrence of the main peak and undershoot of the HRF was computed from the mean of the first and second gamma distributions, respectively. RESULTS: ANOVA and regression analyses found that the timing of the HRF undershoot increased significantly as a function of total lifetime drinking. Although gray matter volume in the motor cortex decreased with lifetime drinking, this was not sufficient to explain undershoot timing shifts, and vascular factors measured in the motor cortex did not differ among groups. Comparison of random-effects analyses using custom-fitted and canonical HRFs for CTL and AUD groups showed better results throughout the brain for custom-fitted versus canonical HRFs for CTL subjects. For AUD subjects, the same was true except for the basal ganglia. CONCLUSIONS: These findings suggest that excessive alcohol consumption is associated with changes in the HRF undershoot. HRF changes could provide a possible biomarker for the effects of lifetime drinking on brain function. Changes in HRF topography affect fMRI activation measures, and subject-specific HRFs generally improve fMRI activation results.

Climate of Fear: Provider Perceptions of Latinx Immigrant Service Utilization.

Latinx immigrants endure stressors throughout the immigration process that detrimentally impact their health and wellbeing. Yet, they also face substantial barriers to accessing and utilizing services. These barriers might be heightened under the Trump administration, which has implemented policies facilitating increased immigration enforcement and punitive immigration practices. This study utilizes data collected from providers who serve Latinx immigrants in the border state of Texas to better understand current immigrant service utilization behaviors. Individual interviews and focus groups were conducted shortly after the last presidential election to inquire about recruitment, retention, program completion, and resources to address key client risk factors. Applying grounded theory analysis strategies, interviews, and focus group recordings were coded for key themes. Data demonstrated central concerns held by providers serving immigrants, and especially those who are undocumented or in mixed-status families. Concerns were related to the following three themes: (1) undocumented immigrant stressors, (2) limited resources for undocumented immigrants, and (3) service utilization barriers. Lack of services for undocumented immigrants and fear related to service utilization were prominent subthemes. These findings extend our knowledge of stressors and barriers of access and utilization for immigrants during this time period of increased immigration enforcement which have valuable implications for practice and future research. Providers can take concrete actions to educate immigrants, regardless of documentation status, on how their clients' identities will be protected. In addition, intentional trust-building strategies are essential to help overcome fear of utilizing services. Future research should ascertain perspectives of immigrant families, as this study drew perspectives only from providers.

Neural Substrates Underlying Eyeblink Classical Conditioning in Adults With Alcohol Use Disorders.

BACKGROUND: Excessive alcohol consumption produces changes in the brain that often lead to cognitive impairments. One fundamental form of learning, eyeblink classical conditioning (EBC), has been widely used to study the neurobiology of learning and memory. Participants with alcohol use disorders (AUD) have consistently shown a behavioral deficit in EBC. The present functional magnetic resonance imaging (fMRI) study is the first to examine brain function during conditioning in abstinent AUD participants and healthy participants. METHODS: AUD participants met DSM-IV criteria for alcohol dependence, had at least a 10-year history of heavy drinking, and were abstinent from alcohol for at least 30 days. During fMRI, participants received auditory tones that predicted the occurrence of corneal airpuffs. Anticipatory eyeblink responses to these tones were monitored during the experiment to assess learning-related changes. RESULTS: Behavioral results indicate that AUD participants showed significant conditioning deficits and that their history of lifetime drinks corresponded to these deficits. Despite this learning impairment, AUD participants showed hyperactivation in several key cerebellar structures (including lobule VI) during conditioning. For all participants, history of lifetime drinks corresponded with their lobule VI activity. CONCLUSIONS: These findings suggest that excessive alcohol consumption is associated with abnormal cerebellar hyperactivation and conditioning impairments.

Ghrelin: From a gut hormone to a potential therapeutic target for alcohol use disorder.

Alcohol use disorder (AUD) is a leading cause of morbidity and mortality worldwide. However, treatment options, including pharmacotherapies, are limited in number and efficacy. Accumulating evidence suggests that elements of the gut-brain axis, such as neuroendocrine pathways and gut microbiome, are involved in the pathophysiology of AUD and, therefore, may be investigated as potential therapeutic targets. One pathway that has begun to be examined in this regard is the ghrelin system. Here, we review preclinical and clinical data on the relationship between ghrelin and alcohol-related outcomes, with a special focus on the role of the ghrelin system as a treatment target for AUD. Observational studies indicate that endogenous ghrelin levels are positively associated with craving for alcohol, subjective responses to alcohol, and brain activity in response to alcohol cues. Knockout rodent models suggest that deletion of the ghrelin peptide or receptor gene leads to reduction of alcohol intake and other alcohol-related outcomes. Different research groups have found that ghrelin administration increases, while ghrelin receptor (GHS-R1a) blockade reduces alcohol intake and other alcohol-related outcomes in rodents. Ghrelin administration in heavy-drinking individuals increases alcohol craving and self-administration and modulates brain activity in response to alcohol reward anticipation. PF-5190457, a GHS-R1a blocker, has been shown to be safe and tolerable when co-administered with alcohol. Furthermore, preliminary results suggest that this compound may reduce cue-elicited craving for alcohol in heavy-drinking individuals - a finding in need of replication. Collectively, the existing literature supports further examination of the ghrelin system as a therapeutic target for AUD. More research is also needed to understand the biobehavioral and molecular mechanisms underlying ghrelin's functions and to examine different interventional approaches to target the ghrelin system for AUD treatment.

Provider ambivalence about using forensic medical evaluation to respond to child abuse: A content and discourse analysis.

Forensic medical evaluation rates for child abuse victims in Texas are low relative to national rates. In exploring reasons, researchers collected quantitative and qualitative interview and focus group data from multidisciplinary child abuse response team members across the state. This paper presents results of a secondary analysis of (N=19) health care providers' interview and focus group transcripts, looking specifically at experiences with conducting forensic evaluations - thoughts, struggles, and ethical issues. The analysis was conducted from a critical realist perspective using content and discourse analysis. A theme of ambivalence was identified and explored. Three discursive themes were identified: ambivalence about the legal role, the health care role, and about unintended outcomes of evaluations. Extra-discursive elements related to the physical body, resource distribution, and funding policy were examined for their interaction with discursive patterns. Implications of findings include addressing issues in the current approach to responding to child abuse (e.g., uniting around common definitions of abuse; refining parameters for when FME is helpful; shoring up material resources for the abuse response infrastructure) and considering modification of providers' roles and activities relative to forensic work (e.g., deploying providers for prevention activities versus reactive activities).

Attentional bias for nondrug reward is magnified in addiction.

Attentional biases for drug-related stimuli play a prominent role in addiction, predicting treatment outcomes. Attentional biases also develop for stimuli that have been paired with nondrug rewards in adults without a history of addiction, the magnitude of which is predicted by visual working-memory capacity and impulsiveness. We tested the hypothesis that addiction is associated with an increased attentional bias for nondrug (monetary) reward relative to that of healthy controls, and that this bias is related to working-memory impairments and increased impulsiveness. Seventeen patients receiving methadone-maintenance treatment for opioid dependence and 17 healthy controls participated. Impulsiveness was measured using the Barratt Impulsiveness Scale (BIS-11; Patton, Stanford, & Barratt, 1995), visual working-memory capacity was measured as the ability to recognize briefly presented color stimuli, and attentional bias was measured as the magnitude of response time slowing caused by irrelevant but previously reward-associated distractors in a visual-search task. The results showed that attention was biased toward the distractors across all participants, replicating previous findings. It is important to note, this bias was significantly greater in the patients than in the controls and was negatively correlated with visual working-memory capacity. Patients were also significantly more impulsive than controls as a group. Our findings demonstrate that patients in treatment for addiction experience greater difficulty ignoring stimuli associated with nondrug reward. This nonspecific reward-related bias could mediate the distracting quality of drug-related stimuli previously observed in addiction.

Preventing subsequent births for low-income adolescent mothers: an exploratory investigation of mediating factors in intensive case management.

We used a quasi-experimental design to examine the impact of intensive case management (ICM) on preventing 3-year subsequent births for low-income adolescent mothers. We used χ(2) and mediation analyses, respectively, to test whether ICM reduced likelihood of subsequent births and whether birth control and perceived social support mediated this relationship. Participants in ICM were less likely to have a subsequent birth within 3 years, but we found no evidence for mediators. This study suggests that ICM may be effective in preventing subsequent births for adolescents.
