RESUMO

Giving and receiving help are integral to creating the social environments necessary to support recovery. However, studies assessing the effects of helping behaviors have focused primarily on the benefits derived from giving help to others in 12-step programs and treatment. The current study examined the frequency of giving and receiving help among 188 persons entering sober living houses (SLHs), a type of recovery home that is common in California. Helping was assessed in three contexts: the SLH, 12-step meetings they attended, and interactions with their family and friends. Residents who gave help to others in one of these contexts tended to also receive help in that context. Residents who reported giving or receiving help in one context tended to report giving and receiving help in other contexts. Study findings suggest helping in recovery occurs in a broader, more reciprocal manner than currently conceptualized. Studies should address how giving and receiving help in different contexts affects recovery outcomes. Research is also needed to describe the determinants of giving and receiving help. Considerations for facilitating help among SLH residents are described.

RESUMO

Background: Sober living houses are designed for individuals in recovery to live with others in recovery, yet no guidelines exist for the time needed in a sober living house to significantly impact outcomes.Objectives: To examine how the length of stay in sober living houses is related to substance use and related outcomes, focusing on early discontinuation (length of stay less than six months) and stable residence (length of stay six months or longer).Methods: Baseline and 12-month data were collected from 455 sober living house residents (36% female). Longitudinal mixed models tested associations between early discontinuation vs. stable residence and abstinence, recovery capital, psychiatric, and legal outcomes. Final models were adjusted for resident demographics, treatment, 12-step attendance, use in social network, and psychiatric symptoms, with a random effect for house.Results: Both early discontinuers (n = 284) and stable residents (n = 171) improved significantly (Ps ≤ .05) between baseline and 12 months on all outcomes. Compared to early discontinuation, stable residence was related to 7.76% points more percent days abstinent (95% CI: 4.21, 11.31); 0.88 times fewer psychiatric symptoms (95% CI: 0.81, 0.94); 0.84 times fewer depression symptoms (95% CI: 0.76, 0.92); and lower odds of any DSM-SUD (OR = 0.65, 95% CI: 0.47, 0.89) and any legal problems (OR = 0.58, 95% CI: 0.40, 0.86).Conclusion: In this study of sober living houses in California, staying in a sober living house for at least six months was related to better outcomes than leaving before six months. Residents and providers should consider this in long-term recovery planning.

RESUMO

OBJECTIVE: Sober living houses (SLHs) are abstinence-based environments designed for individuals in recovery to live with others in recovery. Research shows that SLHs help some individuals maintain recovery and that certain SLH-related factors may be particularly protective. Here we assess how SLH housing and neighborhood characteristics are related to abstinence and psychiatric symptoms over time. METHOD: Baseline, 6-month, and 12-month data were collected from 557 SLH residents. Multilevel mixed models tested associations between house and neighborhood characteristics and individual-level percent days abstinent (PDA) and the number of psychiatric symptoms (measured with the Psychiatric Diagnostic Screening Questionnaire [PDSQ]) as outcomes. Final models adjusted for sex, age, and race/ethnicity; ratings of house characteristics; and objective measurements of neighborhood-level exposures. RESULTS: Both PDA and PDSQ improved significantly (ps ≤ .05) over time in both unadjusted and adjusted models. More self-help groups and fewer alcohol outlets within one mile were significantly protective for PDA, whereas walkability was significantly related to worse PDA and PDSQ (ps ≤ .05). For house-level factors, better ratings of house maintenance were related to significantly fewer psychiatric symptoms, whereas higher scores on SLH's safety measures and personal or residence identity were related to more psychiatric symptoms (ps ≤ .05). No house-level factor was significantly related to PDA. CONCLUSIONS: Neighborhood-level factors such as increased availability of self-help groups and fewer nearby alcohol outlets may increase abstinence among individuals living in SLHs. House-level factors related to better maintenance may also facilitate improved mental health.

RESUMO

Studies show individuals living in residential recovery homes on average make significant improvements in multiple areas of functioning. Residents who achieve and maintain complete abstinence have particularly good outcomes. Residents who relapse after entering the houses have been studied minimally. The current study examined outcomes for 197 residents who relapsed within six months after entering sober living houses (SLHs), which is one type of residential recovery home that is common in California. Despite having relapsed, these residents made significant improvements between entry into the house and 6-month follow-up on measures of percent days abstinent from alcohol and drugs (PDA), psychiatric symptoms, severity of employment problems, and stable housing. Higher recovery capital predicted higher PDA (coefficient = 0.28, SE = 0.09, p = .001) and lower severity of employment problems (coefficient = -0.00, SE = 0.00, p = .007). Recovery capital showed a significant decrease between baseline and 6-month follow-up among persons who relapsed and were no longer living in the house. SLH providers can draw upon social model recovery principles to enhance recovery capital. However, residents should also seek other sources of recovery capital outside the SLH, which may be particularly important for individuals who leave the home.

RESUMO

OBJECTIVE: To identify neighborhood factors associated with recovery outcomes for sober living house (SLH) residents. METHODS: Six-month longitudinal data for new SLH residents (n = 557) was linked with census tract data, services available, alcohol outlets, and Walk Scores® (0-100 score indicating access to neighborhood resources) for 48 SLHs in 44 neighborhoods in Los Angeles County. RESULTS: Non-significant neighborhood characteristics in separate regressions for all outcomes were residents' ratings of perceived risk, percentage of residences with access to a car, percentage of homes over $500,000, percentage of renter-occupied units, percentage with income less than $25,000, percentage that were non-white, the density of substance inpatient within 10 miles, and transit scores from Walk Score®. Multilevel regressions found outpatient substance abuse treatment and density of AA groups were positively associated with more abstinent days. No neighborhood variables were associated with psychiatric symptoms. Higher perceived neighborhood cohesion, lower crime ratings, and better transportation ratings were associated with higher recovery capital. CONCLUSION: Greater neighborhood densities of substance abuse services and AA groups may help residents achieve more days abstinent. While residents may achieve better substance use outcomes even with negative perceptions of the neighborhood, positive perceptions of the neighborhoods may help them acquire more recovery capital.

RESUMO

Background: The settings where we live shape our daily experiences and interactions. Social environment and physical setting characteristics may be particularly important in communal living services, such as recovery homes for alcohol and drug disorders. Objectives: This paper describes the measurement and mobilization of architectural characteristics in one type of recovery home, sober living houses (SLHs). The Recovery Home Architecture Scale (RHAS) is a 25-item measure comprised of six subscales designed to assess architecture in SLHs. Results: Using a sample of 528 individuals residing in 41 houses, we found the RHAS had good interrater reliability, factor structure, and internal consistency. The measure also showed modest construct validity. The RHAS was not associated with length of stay (LOS) but did interact with a measure of the social environment that predicted LOS, the Recovery Home Environment Scale (RHES). Conclusions: Future studies should include a more diverse sample of SLHs and assess how house management, recovery capital, and other factors work in concert with architecture.

RESUMO

AIMS: Studies have shown persons living in recovery homes for drug and alcohol problems make significant, sustained improvements. However, there is limited information about factors associated with outcomes. This study examined how perceptions of social environment of one type of recovery home, sober living houses (SLHs), were associated with length of stay (LOS). METHODS: SLH residents and their house managers (N = 416) completed the recovery home environment scale (RHES) that assessed social model recovery characteristics and the community-oriented program evaluation scale (CPES) that evaluated perceptions of the program environment. RESULTS: Scales completed by residents predicted LOS, but those completed by house managers did not. Larger discrepancies between the two groups were associated with shorter LOS. The RHES was shown to be a stronger predictor of LOS than the CPES. CONCLUSION: Results highlight the importance of the social environment in SLHs, particularly those most closely aligned with social model recovery principles.

RESUMO

BACKGROUND: Recovery homes for persons with alcohol and drug problems provide an abstinent living environment and social support for recovery. Research shows residents in these homes make significant, sustained improvements. However, descriptions of recovery environments within the homes have been limited. PURPOSE: The current study assessed psychometric properties for the Recovery Home Environment Scale (RHES), which assessed social environments within one type of recovery home, sober living houses (SLHs). METHODS: 373 residents were interviewed at entry into the house, 1-month follow-up, and 6-month follow-up. Measures included the RHES, other measures of the social environment, days of substance use, and length of stay. RESULTS: Principal components analysis suggested the RHES was largely unidimensional. Exploratory factor analysis suggested items could be grouped into recovery support (3 items) and recovery skills (5 items). Cronbach's alphas for the full scale and the recovery support and recovery skills subscales were 0.91, 0.89, and 0.87, respectively. As hypothesized, construct validity of the RHES was supported by correlations with other measures of the social environment and predictive validity was supported by associations with length of stay and substance use. CONCLUSIONS: SLHs have been described as "the setting is the service." However, the field has lacked a way to capture characteristics of the social environment. The RHES represents a new way to measure the recovery environment by focusing on social interactions among residents within SLHs and shared activities in the community.

RESUMO

BACKGROUND: Alcohol and drug treatment providers are increasingly emphasizing the role of long-term, community-based systems of care. A good example is Sober Living Houses (SLHs), which are peer operated alcohol- and drug-free living environments. Studies show residents of SLHs make significant improvements in multiple areas. However, little attention has been devoted to describing the critically important role of SLH managers who oversee these homes. METHODS: Thirty-five SLH managers completed interviews about the characteristics and operations of their houses, their activities as managers, and ways their own recovery was affected by their work. RESULTS: Managers reported widespread use of some but not all principles of social model recovery. Manager roles varied dramatically in terms of time spent managing houses, activities related to their roles, and training they received. Some reported extensive amounts of time proving support to residents, while others viewed their role as primarily administrative. CONCLUSIONS: Research is needed to understand reasons for manager differences, optimal manager functioning, and manager training needs. Research is also needed to assess whether different house characteristics require different manager roles.

RESUMO

Understanding the effects of COVID-19 mitigation for persons in group living environments is of critical importance to limiting the spread of the virus. In the U.S., residential recovery homes for persons with alcohol and drug disorders are good examples of high-risk environments where virus mitigation procedures are essential. The National Alliance for Recovery Residences (NARR) has taken recommendations developed by the Center for Disease Control (CDC) and applied them to recovery home settings. This paper describes how COVID-19 mitigation efforts in recovery homes may be influenced by two factors. First, while some houses are licensed by states with rigorous health and safety standards, others are not licensed and are subject to less oversight. These homes may be more inconsistent in adhering to mitigation standards. Second, to varying degrees, recovery homes use a social model approach to recovery that contrasts with mitigation procedures such as social distancing and stay-at-home orders. This paper provides examples of ways recovery homes have been forced to adjust to the competing demands of mitigation efforts and social model recovery. The paper also identifies multiple questions that could be addressed by provider-researcher coalitions to inform how social model recovery can navigate forward during the era of COVID-19. As we move forward during the era of COVID-19, providers are encouraged to remember that recovery homes have a history of resilience facing adversity and in fact have their origins in grassroots responses to the challenges of their times.

RESUMO

Sober living houses (SLHs) are an increasingly common element of the recovery support services landscape, yet little is known about their neighborhood context. This study describes neighborhoods in which SLHs are located and examines differences by house characteristics. SLHs in Los Angeles County (N = 297) were geocoded and linked with U.S. Census, alcohol outlet, recovery resources, and accessibility data. Regression analyses tested differences by house characteristics. Co-ed houses were in neighborhoods that were less ethnically diverse and farther away from recovery resources. Larger house capacity was associated with increased density of off-premise alcohol outlets but also increased proximity to treatment. Higher fees were associated with lower neighborhood disadvantage and off-premise alcohol outlet density but the greater distance from treatment programs and other recovery resources. House characteristics are associated with neighborhood factors that both support recovery and place residents at risk.

RESUMO

BACKGROUND: Recovery capital refers to internal and external resources that facilitate recovery from alcohol and drug disorders. Examples include support from friends and family, access to health and other services, stable housing and finances, and internal assets, such as self-esteem and motivation. Recovery capital is receiving increased emphasis as an integral component of addiction services. However, there are a limited number of studies assessing recovery capital in different settings. METHODS: The current study assessed recovery capital among 363 individuals entering sober living recovery homes (SLHs) and showed how recovery capital was associated with individual and social environment characteristics of the houses. Individual characteristics were assessed shortly after residents entered the house (mean=17 days, sd=9.0). Approximately one month later, individuals were interviewed about their perceptions of the social environment within the household. We hypothesized residents' perceptions of social model characteristics within the household would be associated with higher recovery capital. RESULTS: Study findings showed individual characteristics associated with recovery capital included motivation, support from friends and family, and 12-step involvement. Perceptions of the social environment assessed by four subscales on the Community Oriented Program Evaluation Scale and a measure of social model characteristics were correlated with recovery capital. Regression analyses controlling for individual characteristics showed modest, but consistent associations with recovery capital. CONCLUSION: Even after relatively short periods of time in SLHs, resident perceptions of the social environment show associations with recovery capital. Additional research is needed to understand causal dynamics of this relationship and associations with outcome.

RESUMO

Safe and stable housing is integral to addiction recovery. Across numerous studies, recovery housing has been found to be associated with improvements in a variety of domains. Although procedures for operating some types of recovery housing have been manualized and national standards established, there are few empirical findings identifying which recovery residence characteristics may lead to improved outcomes. Using data from 330 newly admitted residents recruited from 49 sober living houses in California and re-contacted for 6- and 12-month follow-up interviews, this study examines the effects of organizational, operational, and programming characteristics on substance use, criminal justice, and employment outcomes. Results from multilevel analyses adjusting for resident demographics and length of stay indicate that organizational characteristics were associated with outcomes. Residents recruited from houses that were part of a larger organization or group of houses had increased odds of total abstinence (aOR = 3.98, p < 0.001) and drug abstinence (aOR = 3.19, p < 0.001). Residents recruited from houses that were affiliated with a treatment program had increased odds of employment (aOR = 2.92, p = 0.003). Operational characteristics such as where the house was located and whether the house required incoming residents to be sober for at least 30 days prior to entry were also related to improved outcomes, but additional work is needed to develop tools to assess and measure recovery housing characteristics and to better understand how these factors contribute to improved outcomes.

RESUMO

The failure of incarceration as a response to drug offenses has resulted in new policies supporting community-based alternatives. One challenge has been finding appropriate housing for persons on probation and parole. Sober living houses (SLHs) are alcohol- and drug-free living environments that are increasingly being used as housing options for these individuals. The current study examined 6- and 12-month outcomes for 330 persons on probation or parole who entered 49 SLHs. Residents in 22 houses (n = 149 individuals) were randomly assigned to receive a "Motivational Interviewing Case Management" (MICM) intervention and residents in the other 27 houses (n = 181 individuals) received SLH residency as usual. At 6-and 12-month follow-up, both study conditions showed significant improvement relative to baseline on substance abuse, criminal justice, HIV risk, and employment outcomes. For persons who attended at least one MICM session, there were better criminal justice outcomes compared to the SLH as usual group.

RESUMO

There is a pressing need to identify therapeutic targets in tumors with low mutation rates such as the malignant pediatric brain tumor medulloblastoma. To address this challenge, we quantitatively profiled global proteomes and phospho-proteomes of 45 medulloblastoma samples. Integrated analyses revealed that tumors with similar RNA expression vary extensively at the post-transcriptional and post-translational levels. We identified distinct pathways associated with two subsets of SHH tumors, and found post-translational modifications of MYC that are associated with poor outcomes in group 3 tumors. We found kinases associated with subtypes and showed that inhibiting PRKDC sensitizes MYC-driven cells to radiation. Our study shows that proteomics enables a more comprehensive, functional readout, providing a foundation for future therapeutic strategies.

RESUMO

There is currently a nationwide effort to decrease the number of persons who are incarcerated in jails and prisons. However, many ex-offenders on probation or parole do not have access to affordable housing and larger proportions have histories of HIV risk as well as substance abuse problems. In California, sober living houses (SLHs) are becoming an increasingly popular housing option for these individuals. Based largely on the principles of Alcoholics Anonymous (AA), SLHs require abstinence from alcohol and drugs and provide peer support for recovery. The current study examined the types of problems experienced among 330 ex-offenders with lifetime risk for HIV during the six months prior to entering SLHs. Nearly three fourths (74%) of all ex-offenders entering the houses had at least one HIV risk. The importance of housing was evident in the finding that housing status and participants' perceptions of their housing situation were associated with a variety of problem areas, including substance use, HIV risk, psychiatric severity, and legal problems. SLHs represent an important housing option for ex-offenders, but many residents may need additional services to address various problems.

RESUMO

Recent advances in cancer genomics have revealed 4 distinct subgroups of medulloblastomas, each with unique transcription profiles, DNA alterations and clinical outcome. Molecular classification of medulloblastomas improves predictions of clinical outcome, allowing more accurate matching of intensity of conventional treatments with chemotherapy and radiation to overall prognosis and setting the stage for the introduction of targeted therapies.

RESUMO

Alcohol use disorder has been linked to dysregulation of the brain stress systems, producing a negative emotional state leading to chronic relapsing behavior. Vasopressin receptors appear to have a regulatory role in stress, anxiety, and alcohol. This study evaluated the novel compound, ABT-436, a V1b receptor antagonist, in alcohol-dependent participants in a 12-week clinical trial. Men and women (n=150) who met criteria for DSM-IV alcohol dependence were recruited across four sites. Participants received double-blind ABT-436 or placebo, and a computerized behavioral intervention. ABT-436 was titrated to 800 mg/day during weeks 2-12. Although the primary outcome, percentage of heavy drinking days, was lower in participants receiving ABT-436 compared with placebo, this difference was not statistically significant (31.3 vs 37.6, respectively; p=0.172; d=0.20). However, participants receiving ABT-436 had significantly greater percentage of days abstinent than those receiving placebo (51.2 vs 41.6, respectively; p=0.037; d=0.31). No significant differences were found between treatment groups on any other measures of drinking, alcohol craving, or alcohol-related consequences. Smokers receiving ABT-436 smoked significantly fewer cigarettes per week than those receiving placebo (p=0.046). ABT-436 was well tolerated, with diarrhea (mild-to-moderate severity) being the most common side effect. In subgroup analyses, participants with relatively higher baseline levels of stress responded better to ABT-436 than placebo on select drinking outcomes, suggesting there may be value in testing medications targeting the vasopressin receptor in high stress, alcohol-dependent patients.

RESUMO

Low-loadings of Pt supported over six transition metal carbide (Pt/TMC) powder catalysts were synthesized and evaluated for hydrogen oxidation and evolution reactions in an alkaline electrolyte. The roughness factor of each Pt/TMC catalyst was different, indicating that the carbide supports affect the dispersion of Pt. Furthermore, when normalized by the corresponding roughness factors, all Pt/TMC catalysts were found to have similar intrinsic activities that were comparable to the state-of-the-art commercial Pt/C electrocatalysts.

RESUMO

BACKGROUND: There is a high co-occurrence of cocaine and alcohol use disorders, and patients with both of these problems are difficult to treat. There is a reasonable rationale and some empirical data to justify a pilot trial of an injectable, extended-release formulation of naltrexone for treating co-occurring cocaine and alcohol addiction. METHODS: Eighty cocaine (n = 80) and alcohol dependent, treatment-seeking subjects were randomly assigned to receive either two monthly extended-release injections of naltrexone or two matching placebo injections in an 8-week clinical trial, with weekly medical management plus cognitive behavioral therapy visits. RESULTS: No differences in reduction in cocaine or alcohol use were observed between the injectable naltrexone and placebo groups during the 8-week trial. CONCLUSIONS: Injectable extended-release naltrexone, while an ideal method for ensuring medication adherence in these traditionally hard-to-treat patients, did not result in any measurable reduction in cocaine or alcohol use over the course of 8 weeks of treatment.
