RESUMEN

In addition to concern about physical health consequences of COVID-19, many researchers also note the concerning impact on behavioral health and quality of life due to disruption. The purpose of this paper is to explore pathways of COVID-19 behavioral health and quality of life. We found increased anxiety, depression, and alcohol misuse and that the pandemic exacerbated prior problems. Further community indicators also lead to poorer behavioral health and overall decreased quality of life. The nature of COVID-19 and vast reach of the virus suggests that behavioral health concerns should take a primary role in pandemic recovery.

RESUMEN

Communities of color in the United States have been disproportionately impacted by the COVID-19 pandemic. Studies exploring the mental health implications of these disparities have only just begun to emerge. The purpose of this study is to better understand mental health concerns and test whether social determinants of health and COVID-19-related experiences influence these concerns. In April 2020, we launched a community-based survey for adults across the United States. A total of 341 respondents completed the survey, which included questions about demographics, depression, social isolation, work environment, and preexisting mental health conditions. We generated matched controls by adding county data from the Robert Wood Johnson Foundation to our survey. Chi square, Pearson product-moment correlation, point biserial correlation, and logistic regression were estimated. Our analysis revealed that respondents who identified as Latinx, Latin@, or Hispanic were 10 times more likely to meet the threshold score for depression. Similarly, individuals with prior mental health conditions and those who expressed feelings of social isolation due to COVID-19 were 3 times more likely to meet the threshold score for depression. These results confirm our hypothesis that communities of color will likely experience disproportionate mental health impacts of COVID-19-specifically, the mental health sequela that emerge from exposure, cumulative burden, and social isolation. We discuss the implications for expanding access and quality of health and mental health services to address current inequities.

RESUMEN

This mixed methods pilot investigation evaluated the use of virtual patient simulations for increasing self-efficacy and diagnostic accuracy for common behavioral health concerns within an integrated care setting. A two by three factorial design was employed to evaluate three different simulated training conditions with a sample of 22 Masters level behavioral health students. Results support engagement in virtual patient simulation training to increase students' self-efficacy in brief clinical assessment, and support the use of virtual patient simulations to improve diagnostic accuracy. Results further indicate that virtual patient simulations have sufficient levels of usability and acceptability as a tool for developing brief clinical interviewing skills, and that participants found this method of instruction to be a valuable adjunct to traditional classroom or field based training. Future directions and next steps for the integration of technology enhanced simulations in clinical social services education are explored.

RESUMEN

Social support plays a key role in well-being, yet one of the major preventative efforts for reducing the spread of COVID-19 involves social distancing. During times of crisis, social support is emphasized as a coping mechanism. This requires many people to change their typical ways of connectedness and assumes that people have existing healthy relationships or access to technology. The purpose of this article was to explore the potential impact of COVID-19 on loneliness and well-being. Social support is an important consideration for understanding the impact of COVID-19 Psychological First Aid and Skills for Psychological Recovery, which are tools used to inform response methods to help people connect during isolation and are interventions that could be adapted to COVID-specific needs for what may be a prolonged isolation and postisolation. Given the many unknowns of COVID-19, studies are needed to understand the larger behavioral health impact to ensure resources are available, current, and evidence informed. Future studies are also needed to understand how access to technology may help buffer loneliness and isolation and thus improve the social outcomes of the current pandemic.

RESUMEN

Research from financial stress, disasters, pandemics, and other extreme events, suggests that behavioral health will suffer, including anxiety, depression, and posttraumatic stress symptoms. Furthermore, these symptoms are likely to exacerbate alcohol or drug use, especially for those vulnerable to relapse. The nature of coronavirus disease 2019 (COVID-19) and vast reach of the virus, leave many unknows for the repercussions on behavioral health, yet existing research suggests that behavioral health concerns should take a primary role in response to the pandemic. We propose a 4-step services system designed for implementation with a variety of different groups and reserves limited clinical services for the most extreme reactions. While we can expect symptoms to remit overtime, many will also have longer-term or more severe concerns. Behavioral health interventions will likely need to change overtime and different types of interventions should be considered for different target groups, such as for those who recover from COVID-19, health-care professionals, and essential personnel; and the general public either due to loss of loved ones or significant life disruption. The important thing is to have a systematic plan to support behavioral health and to engage citizens in prevention and doing their part in recovery by staying home and protecting others.

RESUMEN

Understanding the effect of cultural values on depression and how social networks influence these relationships may be important in the treatment of substance-using, Mexican American populations. Latino cultural values, familismo, personalismo, fatalismo, and machismo, may be associated with depression among Latinos. The current study identified the association of traditional Latino values on depressive symptomatology among a sample of Mexican American heroin injectors. A cross-sectional research design and field-intensive outreach methodology were utilized to recruit 227 Mexican American men. Participants were categorized into depressed and nondepressed groups. Relations among cultural values and depression were examined using logistic regression. Findings indicate that drug-using men with higher familismo and fatalismo scores are protected against depressive symptomatology. Relations between familismo and depression seem to be moderated by having a drug use network. In addition, findings reveal that age is inversely related to depressive symptomatology. Young Mexican American heroin users who do not ascribe to traditional Latino values may be highly associated with depression and therefore more vulnerable to riskier drug use behaviors. Moreover, drug-using social networks may affect the protective nature of certain cultural values. Further research is needed to identify whether culturally tailored treatments can cultivate these values while simultaneously undermining the effect of substance-using social networks in order to reduce depression symptoms among this group of high-risk substance users.

RESUMEN

BACKGROUND: Youth experiencing homelessness have elevated rates of mental illness and substance use compared to the general population. However, the extent to which underlying mental health issues may contribute to substance use as a way to manage symptoms and whether mental health treatment may reduce risk for substance use is unclear. This paper investigated these relations in a community sample of homeless youth. METHODS: Youth ages 13-24 (N=416) were interviewed as part of a community count and survey of homeless youth in Houston, Texas. A path analysis examined relations among lifetime diagnoses of ADHD, bipolar disorder, and depression; past-month marijuana, alcohol, and synthetic marijuana use, and hypothesized mediators of past-year mental health treatment and perceived unmet need for treatment. RESULTS: Rates of prior mental disorder diagnoses were high, with extensive comorbidity across the three diagnoses (n=114, 27.3% had all three diagnoses). Relations varied by diagnoses and substances. ADHD was positively related to current marijuana use (ß=0.55 (0.16), p<0.001), a relation that mental health treatment did not mediate. Depression was positively related to synthetic marijuana use through unmet need (ß=0.25 (0.09), p=0.004) and to alcohol use through unmet need (ß=0.20 (0.10), p=0.04) CONCLUSIONS: This study provides new information about relations between prior mental health diagnoses and substance use in homeless youth. Findings support the need to consider prior mental disorder diagnoses in relation to current substance use and to assess for whether youth perceive they have unmet needs for mental health treatment.

RESUMEN

The influence of the family is not well understood as it relates to drug use behaviors of Hispanic male adults. We examined the family's influence on drug use behavior, as perceived by Hispanic men who use heroin. One-time qualitative interviews were conducted with 21 current and former heroin users who participated in a larger study on long-term heroin use in Mexican-American men. Data were analyzed using a thematic analysis approach. Three main themes emerged: family as a supportive environment for heroin use; heroin as a family legacy; and, the family's strategies for helping to stop using heroin. A sub-theme emerged on the paradox of family involvement, which spanned the three main themes. This research lays a foundation for future work to disentangle the risks and benefits of family involvement to inform culturally-centered therapies and cultural adaptations to traditional therapeutic approaches with Mexican-American men who abuse drugs.

RESUMEN

INTRODUCTION: Virtual reality (VR) has been shown to be effective in eliciting responses to nicotine cues in cigarette smokers. The primary aim of this study was to investigate whether cigarette-deprived smokers would exhibit increased craving and changes in heart rate when viewing cigarette related cues as compared to non-smoking cues in a VR environment, and the secondary aim was to assess the extent to which self-assessed measures of withdrawal and dependence correlated with VR craving. METHODS: Nicotine-dependent cigarette smokers were recruited for a 2 day study. On Day 1, participants smoked as usual and on Day 2 were deprived from smoking overnight. On both days, participants completed self-assessment questionnaires on withdrawal, craving, and nicotine-dependence. Participants completed a VR session during the cigarette deprivation condition only (Day 2). During this session, they were exposed to active smoking and placebo (non-smoking) cues. RESULTS: The data show that self-reported levels of "craving" (p < .01) and "thinking about cigarettes" (p < .0001) were significantly greater after exposure to the active cues versus non-smoking cues. Significant increases in heart rate were found for 3 of 4 active cues when compared to non-smoking cues (p < .05). Finally, significant positive correlations were found between self-reported craving prior to the VR session and craving induced by active VR cues (p < .01). CONCLUSIONS: In this report, active VR cues elicited craving during cigarette deprivation. This is the first study to demonstrate that self-reported craving, withdrawal symptoms, and nicotine dependence severity predict cue-induced craving in the VR setting.

RESUMEN

Drug use among older adults is a growing concern, particularly for the burgeoning Hispanic population. Older adults seeking drug treatment will double over the next decade to almost 6 million. Cultural factors influence drug use, and more specifically, Hispanic cultural values influence heroin use. This study explored Mexican-American injection drug users' adherence to traditional Hispanic cultural values and their impact on cessation. Ethnographic interviews endorsed contextualized influences of values on heroin use. Cultural values functioned dichotomously, influencing both initiation and cessation. Understanding the impact of cultural values on substance abuse is critical given the changing demographics in American society.

RESUMEN

BACKGROUND: This study explores the spatial accessibility of outpatient drug treatment facilities and the potential relationship with drug use-related outcomes among Mexican American heroin users. METHODS: Secondary data on 219 current and former heroin-injecting Mexican American men aged 45 and older were drawn from a research study in Houston, Texas. We used geographic information systems (GIS) to derive two spatial accessibility measures: distance from one's place of residence to the closest drug treatment facility (in minutes); and the number of facilities within a 10-minute driving distance from one's place of residence. Exploratory logistic regression analyses examined the association between the spatial accessibility of drug treatment facilities and several drug use-related outcomes: internal locus of control (LOC); perceived chances and worries of injecting in the next six months; treatment utilization; and location of last heroin purchase. RESULTS: Participants with greater spatial access to treatment programs were more likely to report a higher chance of injecting in the near future. However, while current heroin users were more worried about injecting in the next six months, greater spatial access to treatment programs seemed to have a buffering effect. Finally, those who lived closer to a treatment programs were more likely to have last purchased heroin inside the neighborhood versus outside the neighborhood. Spatial accessibility was not associated with internal LOC or treatment utilization. CONCLUSION: The findings showed that the presence of outpatient treatment facilities-particularly services in Spanish-may influence perceived risk of future heroin use and purchasing behaviors among Mexican American men. Implications for future spatially-informed drug use research and the planning of culturally and linguistically responsive drug treatment programs are discussed.

RESUMEN

This article describes social capital in a cohort of 227 Mexican American men who are long-term injection heroin users. Social capital scores for current and former users were similar, suggesting equal absolute values of capital, but associated with illicit activities in current users and with cessation efforts in former users. Stable drug-using relationships provided high negative capital, whereas conventional relationships provided positive capital. Thus, social capital functions dichotomously in positive and negative contextualized roles. This study provides an alternative understanding of the dynamic interactions between individuals, environment, and drug abuse and can inform prevention and treatment interventions for an important demographic group.

RESUMEN

Rates of cigarette smoking are 3- to 4-fold greater among those with cocaine-dependence, and compared to non-users, cocaine users are at greater risk of incurring smoking-related negative health effects and death. The current study examined D-cycloserine's (0 or 50mg once weekly) effects on 1) extinction of cue-induced craving for cigarettes, 2) cigarette smoking in conjunction with cognitive-behavioral therapy, and 3) safety and tolerability in cocaine-dependent smokers. This was a double-blind, placebo-controlled, between groups, outpatient study. Participants (N=29) were concurrent cocaine- and nicotine-dependent volunteers seeking treatment for their cigarette smoking. Study visits were 3 times per week for 4 consecutive weeks. At each visit, participants received cognitive-behavioral therapy for smoking, were exposed to smoking cues. A subset of participants (N=22) returned for 6-month follow-up visits. While craving decreased, no significant effects of D-cycloserine treatment were observed. Likewise, significant decreases in smoking were observed at study days 6 (p<0.002) and 12 (p<0.0001) relative to baseline, although no participants achieved complete abstinence. However, there was no effect of D-cycloserine on cigarette smoking during treatment or at 6-mos follow-up. The treatment was safe and tolerable, with nearly 90% of treatment sessions attended based on an intent-to-treat analysis. While no effects of D-cycloserine on craving or smoking were observed in the current study, the results do suggest that smoking treatment is well accepted and may be effective for cocaine-dependent individuals.

RESUMEN

This study was an open-label, single-group, treatment-development project aimed at developing and testing a method for applying virtual reality exposure therapy (VRET) to active duty service members diagnosed with combat post-traumatic stress disorder (PTSD). Forty-two service members with PTSD were enrolled, and 20 participants completed treatment. The PTSD Checklist-Military version, Patient Health Questionnaire-9 for depression, and the Beck Anxiety Inventory were used as outcome measures. Of those who completed post-treatment assessment, 75% had experienced at least a 50% reduction in PTSD symptoms and no longer met DSM-IV criteria for PTSD at post treatment. Average PSTD scores decreased by 50.4%, depression scores by 46.6%, and anxiety scores by 36%. Intention-to-treat analyses showed that statistically significant improvements in PTSD, depression, and anxiety occurred over the course of treatment and were maintained at follow up. There were no adverse events associated with VRET treatment. This study provides preliminary support for the use of VRET in combat-related PTSD. Further study will be needed to determine the wider utility of the method and to determine if it offers advantages over other established PTSD treatment modalities.

RESUMEN

Cue reactivity assessments have been widely used to assess craving and attention to cues among cigarette smokers. Cue reactivity has the potential to offer insights into treatment decisions; however, the use of cue reactivity in treatment studies has been limited. This study assessed the feasibility of using a virtual reality-based cue reactivity assessment approach (VR-NCRAS) during treatment. In a clinical smoking cessation treatment study, 46 treatment-seeking nicotine-dependent adult smokers were assessed for cue reactivity at baseline, Week 4, and Week 10 of treatment. Measures of cue reactivity included subjective craving and attention to cues after exposure to two neutral and two smoking cue environments. Overall, feasibility of using VR-NCRAS was demonstrated and these findings support the use of the cue reactivity assessment during treatment, which can inform treatment decisions.

RESUMEN

OBJECTIVE: Virtual reality (VR)-based cue reactivity has been successfully used for the assessment of drug craving. Going beyond assessment of cue reactivity, a novel VR-based treatment approach for smoking cessation was developed and tested for feasibility. METHOD: In a randomized experiment, 10-week treatment feasibility trial, 46 nicotine-dependent adults, completed the10-week program. Virtual reality skills training (VRST) combined with nicotine replacement therapy (NRT) was compared to NRT alone. Participants were assessed for smoking behavior and coping skills during, at end of treatment, and at posttreatment follow-up. RESULTS: Smoking rates and craving for nicotine were significantly lower for the VRST group compared to NRT-only group at the end of treatment. Self-confidence and coping skills were also significantly higher for the VRST group, and number of cigarettes smoked was significantly lower, compared to the control group at follow-up. CONCLUSIONS: Feasibility of VRST was supported in the current study.

RESUMEN

Alcohol and cigarette smoking frequently co-occur among adults in the U.S., resulting in a myriad of deleterious health outcomes. Cue reactivity has been posited as one factor that precludes individuals from overcoming alcohol and nicotine dependency. While cue reactivity studies have focused on the impact of proximal cues on cue reactivity, much less is known about the unique impact of complex and contextual cues. This pilot study compares nicotine and alcohol cue reactivity among a sample of nicotine dependent, daily drinkers (N=21) across neutral, party, and office courtyard virtual reality (VR) contexts embedded with proximal smoking cues to: 1) explore and compare the effects of complex nicotine cues on alcohol cross-cue reactivity between nicotine/alcohol dependent drinkers and nicotine dependent/non-alcohol dependent daily drinkers, and 2) assess the effectiveness of VR for eliciting cue-induced nicotine craving responses using complex nicotine cues. Nicotine dependent/non-alcohol dependent drinkers had significantly lower craving for alcohol in the non-alcohol congruent office courtyard VR scene and there was no difference in the alcohol-congruent party scene when compared to the alcohol dependent group, suggesting that the non-alcohol dependent daily drinking group was more likely to react to contextual cues. Consistent with prior cue reactivity studies, dependent smokers experienced significantly higher craving for nicotine in the VR smoking congruent contexts compared to the neutral contexts; however, nicotine/alcohol dependent participants did not return to baseline craving after exposure to smoking cues. These results suggest substantive differences in the ways that nicotine-dependent, daily alcohol drinkers and nicotine/alcohol dependent drinkers experience craving, whether cross-cue or traditional.

RESUMEN

Virtual reality (VR), a system of human-computer interaction that allows researchers and clinicians to immerse people in virtual worlds, is gaining considerable traction as a research, education, and treatment tool. Virtual reality has been used successfully to treat anxiety disorders such as fear of flying and post-traumatic stress disorder, as an aid in stroke rehabilitation, and as a behavior modification aid in the treatment of attention deficit disorder. Virtual reality has also been employed in research on addictive disorders. Given the strong evidence that drug-dependent people are highly prone to use and relapse in the presence of environmental stimuli associated with drug use, VR is an ideal platform from which to study this relationship. Research using VR has shown that drug-dependent people react with strong craving to specific cues (e.g., cigarette packs, liquor bottles) as well as environments or settings (e.g., bar, party) associated with drug use. Virtual reality has also been used to enhance learning and generalization of relapse prevention skills in smokers by reinforcing these skills in lifelike environments. Obesity researchers and treatment professionals, building on the lessons learned from VR research in substance abuse, have the opportunity to adapt these methods for investigating their own research and treatment questions. Virtual reality is ideally suited to investigate the link between food cues and environmental settings with eating behaviors and self-report of hunger. In addition, VR can be used as a treatment tool for enhancing behavior modification goals to support healthy eating habits by reinforcing these goals in life-like situations.

RESUMEN

Cigarette smokers in laboratory experiments readily respond to smoking stimuli with increased craving. An alternative to traditional cue-reactivity methods (e.g., exposure to cigarette photos), virtual reality (VR) has been shown to be a viable cue presentation method to elicit and assess cigarette craving within complex virtual environments. However, it remains poorly understood whether contextual cues from the environment contribute to craving increases in addition to specific cues, like cigarettes. This study examined the role of contextual cues in a VR environment to evoke craving. Smokers were exposed to a virtual convenience store devoid of any specific cigarette cues followed by exposure to the same convenience store with specific cigarette cues added. Smokers reported increased craving following exposure to the virtual convenience store without specific cues, and significantly greater craving following the convenience store with cigarette cues added. However, increased craving recorded after the second convenience store may have been due to the pre-exposure to the first convenience store. This study offers evidence that an environmental context where cigarette cues are normally present (but are not), elicits significant craving in the absence of specific cigarette cues. This finding suggests that VR may have stronger ecological validity over traditional cue reactivity exposure methods by exposing smokers to the full range of cigarette-related environmental stimuli, in addition to specific cigarette cues, that smokers typically experience in their daily lives.

RESUMEN

Virtual reality (VR) cue environments have been developed and successfully tested in nicotine, cocaine, and alcohol abusers. Aims in the current article include the development and testing of a novel VR cannabis cue reactivity assessment system. It was hypothesized that subjective craving levels and attention to cannabis cues would be higher in VR environments with cannabis cues compared to VR neutral environments. Twenty nontreatment-seeking current cannabis smokers participated in the VR cue trial. During the VR cue trial, participants were exposed to four virtual environments that contained audio, visual, olfactory, and vibrotactile sensory stimuli. Two VR environments contained cannabis cues that consisted of a party room in which people were smoking cannabis and a room containing cannabis paraphernalia without people. Two VR neutral rooms without cannabis cues consisted of a digital art gallery with nature videos. Subjective craving and attention to cues were significantly higher in the VR cannabis environments compared to the VR neutral environments. These findings indicate that VR cannabis cue reactivity may offer a new technology-based method to advance addiction research and treatment.
