Cannabis Adaptation During and After Alcohol Ignition Interlock Device Installation: A Longitudinal Study

OBJECTIVE

A common intervention to prevent alcohol-impaired driving are alcohol ignition interlock devices (IIDs), which prevent drivers with a blood alcohol concentration greater than .025% from starting the car. These devices force drivers to adapt their drinking to accommodate the device. Prior studies indicated a transfer of risk as some drivers with an IID may increase cannabis use as they decrease alcohol use. This study examines whether this increase in cannabis use persists after IID removal when alcohol use reverts to pre-IID levels.

METHOD

The data are from the Managing Heavy Drinking (MHD) study of drivers in New York State. The MHD is a comprehensive three-wave study of drivers convicted of driving under the influence from 2015 to 2020. Participants (N = 189) completed all waves, and provided oral fluid/blood and hair samples to measure cannabis and alcohol use, respectively. Mixed between-within analysis of variance was conducted to assess cannabis use at IID installation (Time 1), removal (Time 2), and at 6-month follow-up (Time 3).

RESULTS

In aggregate, participants increased their cannabis use over the course of the study. Drivers who decreased their alcohol use while the IID was installed on their car significantly increased their cannabis use while the IID was in place and further increased cannabis use after the device's removal.

CONCLUSIONS

IIDs are efficacious in preventing alcohol-impaired driving. However, in some cases, they may have the unintended effect of increasing other substance use. The current study outlines the need for supplemental treatment interventions while on IID to prevent a transfer of risk to other substances, or polysubstance use after the device is removed.

Examining the role of trauma in alcohol interlock performance: A structural pathway analysis

OBJECTIVE

Self-medication using alcohol is a common coping response among individuals dealing with trauma as is driving under the influence of alcohol (DUI). A common intervention for drivers convicted of DUI, is an alcohol ignition interlock device (IID)-which requires breath samples before starting the car. If the sample is above a predetermined limit (.025), the car will not start, thus preventing impaired driving. IIDs are an effective intervention to reduce rates of drinking and driving among high risk populations; however, limited research has examined how traumatic experiences may impact performance on IIDs.

METHODS

This study is an archival analysis of the Managing Heavy Drinking (MHD) study of drivers in New York state. The MHD is a comprehensive study of drivers convicted of a DUI from 2015-2020. Participants (N = 121) completed questionnaires and provided consent to retrieve information from interlock providers. Outcome variable included high BAC lockout ratios (number of high BAC lockouts [BAC>.08]/number of clean blows [BAC ≤ .025]). Other variables included demographic variables, alcohol treatment history, trauma experiences, and prior DUI history. Variables were entered into a structural equation model.

RESULTS

In the final structural model, pathways that demonstrated a p-value of greater than .10 were dropped from the model. This produced acceptable overall model fit statistics (χ2 = 27.059(10), p=.003; CFI = .900; NFI = .898; RMSEA = .063). A significant pathway was found from the trauma measure to alcohol use (β = .132), and from alcohol use to interlock performance (β = .636). However, no significant relationship was found between trauma and interlock performance other than through alcohol use.

CONCLUSIONS

The current study provides a useful framework upon which to understand the role traumatic experiences have on alcohol IID performance. Traumatic experiences are in of themselves insufficient to impact IID performance directly, but it may indirectly impact IID performance through increasing alcohol use.

Twelve-month organizational study examining the associations among behavioral healthcare worker's perceptions of autonomy, decision-making power, organizational commitment, and burnout: Reconceptualizing the role of commitment in shaping staff member experiences of the work environment

Previous research has demonstrated that behavioral healthcare workers' experiences of autonomy and decision-making power in the workplace are positively associated with their commitment to the organization and negatively associated with occupational burnout. Models examining the relationships between workplace climate and staff member well-being generally conceptualize workplace climates as predictors of individual commitment and burnout. However, the relationships among these constructs have primarily been explored in cross-sectional study designs. The current study adds to the existing literature by examining the relationships among perceived autonomy and decision-making power in the organizational climate, and individual levels of organizational commitment and burnout over a 12-month period (N = 43). The study was done in a public hospital's behavioral healthcare department in the Western New York region. Cross-lagged panel analyses were conducted to assess if time-one scores on perceived autonomy and decision-making power predicted time-two scores of organizational commitment and burnout. Findings indicate that, contrary to popular conceptualization, individual staff member's commitment to the organization predicted future states of perceived autonomy and decision-making power. Individual commitment to the organization may be a driving factor in how staff members experience and perceive the service environment.

Convicted drinking and driving offenders: Comparing alcohol use before and after the pandemic outbreak

Background

Before the COVID‐19 pandemic, very little was known about the impact of social isolation on individuals’ alcohol use and misuse. This study examines how socially isolated individuals with a history of heavy drinking used alcohol during the pandemic.

Methods

Data for this study came from an add‐on to the Managing Heavy Drinking (MHD) longitudinal study of drivers convicted of DWI that was conducted in Erie County, New York. Pre‐COVID information (October 2019–March 2020) was augmented with a COVID‐19 questionnaire collected between July and August 2020. A total of 92 participants completed the COVID‐19 survey.

Results

The sample of problem drinkers showed a significant increase after the pandemic outbreak in the average number of drinking days from 1.99 to 2.49 per week (p = 0.047), but a significant decrease in the average number of drinks per drinking day, from 3.74 to 2.74 (p = 0.003). The proportion of individuals who drank more frequently was greater among those who, before the outbreak had an Alcohol Use Disorders Identification Test (AUDIT) score <8 (26% increase) compared with those with an AUDIT score of >8 (13%). Alcohol treatment was also associated with the frequency of drinking, with individuals who were not in alcohol treatment showing a 16% increase in frequency compared with a 10% increase among those in treatment. Further, individuals who, after the outbreak worried about their health (30%) or finances (37%) reported greater increases in the frequency of drinking than those who did not worry about their health (17%) or finances (10%).

Conclusions

Overall, the individuals in our sample showed small changes in the frequency andheaviness of drinking after the outbreak of COVID‐19, effects that opposite in direction from one another and thus resulted in no overall change in drinks consumed. Nonetheless, we identified factors that influenced the effects of the pandemic on drinking behavior among individuals convicted of DWI, which emphasizes the need to individualize these individuals’ treatment, particularly in the context of dramatic environmental change.

Changes in Alcohol Use and Drinking and Driving Outcomes From Before Arrest for Driving Under the Influence to After Interlock Removal

BACKGROUND

Half of the offenders convicted of impaired driving in the United States are sentenced to install alcohol ignition interlock devices (IIDs), which prevent them from starting their vehicles if they have been drinking. No research has yet explored offenders' patterns of alcohol consumption and driving under the influence of alcohol (DUI) from the time before the arrest to the time period after the IID is installed. This study aims to fill that gap in knowledge.

METHODS

Using the Timeline Follow-back interview procedure, we assessed the daily drinking of 153 convicted DUI offenders' self-reported total alcohol consumption and rates of self-reported driving after drinking over 4 phases: before DUI arrest, between arrest and IID installation, during the phase on the interlock, and after the interlock is removed. Because information about behaviors in each period was not available for every participant, comparisons were made using paired-sample contrasts.

RESULTS

Compared with before the arrest, total alcohol use decreased by 50% in the 4-month phase following arrest and before IID installation, though it did not change much afterward. The frequency of drinking and driving decreased sharply after the arrest (-82%), with further decrease upon installation of the interlock (-58%, p = 0.05). The frequency of drinking and driving after the IID was removed returned to preinstallation drinking and driving status (+58%, p = 0.01).

CONCLUSIONS

Participants made significant adjustments to their drinking behavior by adhering to the traditional DUI driving restrictions in the postarrest phase. Although installation of an IID was not associated with a significant change in drinking, it further reduced the frequency of drinking and driving. Evaluations of the IID experience should take into account information on an individual's drinking and DUI behaviors not only before the IID was installed, but before the individual was arrested.

Understanding non-installers of the ignition interlock device: A qualitative analysis

INTRODUCTION

Literature notes the efficacious use of alcohol ignition interlock devices (IID) in reducing rates of drinking and driving while installed on the vehicle. Some drivers who are convicted of driving while intoxicated (DWI) elect to have their license suspended/revoked instead of installing the device. These individuals represent a high-risk subsample of drivers, yet limited literature has addressed this concern. The current study seeks to fill this gap using qualitative interviews addressing: (i) why do non-installers make the choice to not install a mandated IID; and (ii) how are non-installers managing without the IID?

METHODS

The study utilises the Managing Heavy Drinkers study of drivers in Erie County, New York, USA. Participants were purposively sampled from a group of non-installers (n = 6; four females, two males) who completed semi-structured interviews. Constructed grounded theory was used to develop a theoretical understanding of participant's experiences.

RESULTS

To understand why participants elect not to install the IID, thematic analysis revealed: alleviating constraints, predominantly the financial burdens associated with an IID, and institutional mistrust. Additionally, data revealed that participants are managing without the IID by mitigating apprehension. This included driving cautiously to avoid detection and utilising alternative transportation.

DISCUSSION AND CONCLUSIONS

This study furthers understanding of why drivers convicted of a DWI elect not to install an IID. Future research should seek to identify barriers to IID installation. This work provides evidence for establishing institutional protocols that ensure drivers convicted of a DWI receive consistent and correct information about the IID process.

Is deployment status the critical determinant of psychosocial problems among reserve/guard soldiers?

A general assumption that deployment is the primary catalyst for psychological and social difficulties may contribute to underrecognition and undertreatment of problems among never-deployed service members (i.e., having no history of ever being deployed). We aimed to determine if ever-deployed (i.e., having a history of at least one deployment) and never-deployed United States Army Reserve and National Guard (USAR/NG) soldiers differed in mental health, substance use, and resiliency factors, and to determine the relative influence of deployment status and each of these factors on poor psychosocial outcomes. We analyzed a subset of data from Operation: SAFETY (Soldiers and Families Excelling Through the Years) (N = 404), an ongoing study examining the health and well-being of USAR/NG soldiers. Bivariate analyses demonstrated that soldiers did not significantly differ across a range of measures on the basis of deployment status (ps > 0.05). In fact, Factor Analyses and Discriminant Function Analysis revealed that deployment status was the least salient factor to psychosocial problems among the measured variables and that the observed variables could not accurately discriminate between ever-deployed and never-deployed soldiers, F(8, 374) = 1.34, p > .05. Measures of mental health and substance use were more salient to psychosocial problems (ps < .05). Measures of resiliency loaded negatively onto psychosocial problems (ps < .05), indicating that they contribute to better well-being. Targeting screening and intervention efforts only on soldiers who have been deployed will miss opportunities to intervene on an equally affected group. Resiliency factors should be considered as intervention targets. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

The impact of interlock installation on driving behavior and drinking behavior related to driving

OBJECTIVE

There is a substantial body of evidence that the recidivism of impaired-driving offenders is reduced while an ignition interlock device (IID) is on their vehicles. This study examines changes in driving behaviors and drinking behaviors used by DWI offenders to manage driving with the IID.

METHODS

A total of 166 IID participants who completed two surveys covering the period from arrest to IID installation (T1) and during IID use (T2) were examined. Four domains were covered: demographics, driving environments and transportation needs, reported driving activity, and reported drinking activities. Participants were on average 38 years old, 43% were female, 35% completed college, 34% had an income of more than $50,000, and 83% were employed. For those who provided it, the mean blood alcohol content (BAC) at arrest was .184 g/dL, with only 8 (5%) individuals below .08 g/dL, and 93 (56%) at over .18 g/dL. About 45% were repeat DWI offenders.

RESULTS

Between T1 and T2 there was a slight increase in acknowledging public transportation was available (p=.001), an increase in other individuals driving the interlock-equipped vehicle (p=.002), an increase in the number of vehicles in the household not registered to the DWI offender (p< .001), and an increase in the number of participants who reported that driving was important to their lifestyle (p=.008). Initial (T1) expectations about whether the interlock would be a problem were significantly different from actual experiences reported in T2 (p<.001). With respect to alcohol consumption, 14% reported abstinence at T2 compared to 2% at T1 (p=.001) and the number of drinks per drinking occasion decreased from a mean of 4.90 at T1 to 3.14 at T2 (p=.001), but the number of drinking occasions increased by a third (p=.003). The number of drinking locations (p=.001), the frequency of stopping after work for a drink (p=.001), and drinking at a bar all decreased (p<.001).

CONCLUSIONS

Interlock users make some adjustments in how they drink, the amount they drink, and where they drink. This finding suggests that there may be methods that can be used to extend the benefits of the IID beyond the sanction period.

A structural regression analysis of trauma-informed climate factors, organizational commitment, and burnout among behavioral healthcare providers in a large public hospital

As an approach to organizational change, trauma-informed care is contextualized within the broader organizational literature by examining the associations between organizational conditions (i.e., psychological experiences of choice and collaboration in the work environment) with precursors to organizational effectiveness (i.e., affective commitment and burnout). The study occurred within a large public hospital's behavioral health department located in the Western New York region (N = 197). Structural regression analyses were conducted, and the primary findings, while nuanced, include support for choice and collaboration's prediction of employee commitment and burnout. Organizational interventions that improve worker's experiences of choice and collaboration may result in increased commitment, reduced burnout, and possibly improved effectiveness. Future research should employ longitudinal designs to further examine the condition-performance relationship and include direct measures of clinical effectiveness.

Gender Differences in Complex Posttraumatic Stress Symptoms, and Their Relationship to Mental Health and Substance Abuse Outcomes in Incarcerated Adults

Complex trauma (CT; for example, childhood abuse) has been associated with significant behavioral health problems (i.e., mental health and substance use disorders) and symptoms that are consistent with complex posttraumatic stress disorder (C-PTSD). CT is prevalent in adult forensic populations, and particularly important for women as they tend to report more adverse consequences of exposure to traumatic stressors and are entering the criminal justice system at a heightened rate compared with men. However, no studies have empirically tested the relationship among CT, C-PTSD, and behavioral health problems with gender among incarcerated adults. The present study examined the relationship between gender and childhood abuse history, C-PTSD symptom severity, and behavioral health problems in 497 incarcerated adults. Findings indicate that women were more likely to report a history of childhood abuse, and more severe C-PTSD symptoms and behavioral health problems than men. Childhood abuse history significantly accounted for the gender difference observed in C-PTSD symptom severity. C-PTSD partially mediated the gender difference in psychiatric morbidity and in risk of hard drug use. Implications for trauma-informed and gender-responsive services and research in the adult criminal justice system are discussed.

Psychometric Properties of the Assessment of Recovery Capital (ARC) Instrument in a Diverse Low-Income Sample

Background: Recovery capital is a theoretical construct elucidating the resources that support recovery from addiction. The 50-item Assessment of Recovery Capital (ARC) instrument and related brief-format versions are the predominant measures of this construct. However, some of the ARC's psychometric properties are not well-established, particularly in racially and economically diverse populations. Objectives: We aimed to determine if the ARC is a valid and reliable measure of recovery capital in a diverse sample. Methods: Paper-and-pencil survey data were collected between March 2017 and May 2018 from a low-income, racially diverse sample of adults in recovery (N = 273). Participants were recruited from nontreatment community settings throughout a mid-sized northeastern U.S. city. They completed the ARC and sociodemographic questions. To determine the ARC's reliability and factor structure, we used item-level analyses and Cronbach's alpha, followed by confirmatory and exploratory factor analyses. Results: Several items performed poorly, having means close to response extremes and problematically small variances. Cronbach's alpha for the full measure was α = .92; however, alphas for the majority of subscales were below .70. The a priori 10-factor model solution failed, preventing interpretation of the confirmatory factor analysis results. Exploratory factor analysis revealed that although the 10-factor model marginally fit the data, items did not load together as proposed. Not once did all five subscale items load highly on the same factor. Conclusions/Importance: The ARC has substantial weaknesses in its theoretical alignment, item performance, and psychometric properties with diverse populations. We recommend the development of a new multidimensional, theory-aligned measure, following a rigorous measurement development protocol.

Potential for cannabis adaptation among participants in a drunk driving intervention

Background

Some alcohol interventions have been found to have the adverse outcome of increasing non-alcohol-related substance use. It is unknown, however, how changes in alcohol use over the course of alcohol ignition interlocks - a common DUI intervention - may impact other substance use.

Methods

Alcohol and cannabis use were measured using hair ethylglucuronide and Delta-9-Tetrahydrocannabinol concentrations in blood, respectively. Participants (N = 69) were measured at the interlock installation period and again 6-months later while the interlock was installed. A mixed ANOVA was conducted to examine changes in levels of ethanol and THC over time.

Results

On measures of marijuana use, there was a significant interaction effect between the group that increased alcohol use and time F(2, 66) = 7.863, p =.001; partial η ² =.192; as well as a main effect for time F(2, 66) = 21.106, p <.001; partial η ² =.242.

Conclusions

Installing interlocks may inadvertently increase cannabis use among those who decrease alcohol use. Crash risk associated with cannabis use is notably less than that of alcohol use, however, continued cannabis use may be problematic when the device is removed and alcohol use is expected to return to the higher pre-interlock levels.

A resilience framework: Sexual health trajectories of youth with maltreatment histories

There is a wealth of knowledge regarding negative sexual outcomes experienced by youth with childhood maltreatment (CM) histories, yet a dearth of research examines healthy sexual development among these youth. This gap exists despite evidence of resilience highlighting alternative and healthy physical, social, and psychological futures for youth who were abused. This study tested whether trajectories of resilience identified in studies of psychological functioning were applicable to sexual health. Using data from the first four waves of the National Longitudinal Study of Adolescent to Adult Health, latent class growth analysis was conducted among individuals with histories of CM (N = 1,437). On average, participants were 15, 16, 21, and 28 years old, respectively, by waves of data collection. About half of the sample was female (55%), the majority were White (66%), and a sizeable portion had experienced multiple forms of CM prior to Wave I (38%). Controlling for CM severity, three distinct sexual health trajectory classes were identified: resilient, survival, and improving, which were differentiated by age and biological sex. Older participants' sexual health was more likely to diminish over time, girls were more likely to show gains in sexual health over time, and significant differences in levels of sexual behaviors between the classes were only present during adolescence. Findings support the need for increased attention on the potential for sexual health despite experiences of CM, and highlight the applicability of resilience theory to youth sexuality.

A parenting education program for women in treatment for opioid-use disorder at an outpatient medical practice

Opioid use during pregnancy poses serious risks for the mother and the unborn child. Opioid-use disorder may be managed with medication-assisted treatment (MAT) in an outpatient setting, but few MAT practices specifically address the challenges faced by pregnant women. This article describes a medical office-based educational support group for women in MAT for opioid-use disorder who were pregnant and/or parenting young children. Focus groups were conducted to elicit patient feedback. Women indicated that they found the educational support groups beneficial and offered suggestions. In-office educational support groups for pregnant women in treatment for opioid-use disorder are feasible and well received.

Time spent online: Latent profile analyses of emerging adults' social media use

Studies of youth social media use (SMU) often focus on its frequency, measuring how much time they spend online. While informative, this perspective is only one way of viewing SMU. Consistent with uses and gratification theory, another is to consider how youth spend their time online (i.e., degree of engagement). We conducted latent profile analyses of survey data from 249 U.S. emerging adults (ages 18-26) to explore their SMU in terms of frequency and engagement. We derived separate 3-profile solutions for both frequency and engagement. High frequency social media users tended to be women and to have more Facebook friends. Highly engaged users (i.e., those most interactive online) tended to be White and more highly educated. Findings from this exploratory study indicate that youth SMU frequency and SMU engagement warrant separate consideration. As SMU becomes more ingrained into the fabric of daily life, it is conceivable that engagement may be a more meaningful way to assess youth SMU, especially in relation to the digital divide, since it can be used to meet important needs, including social interaction, information exchange, and self-expression.

Examining the Relationship between Psychological Functioning, Childhood Trauma, and Types of Perceived Coercion Among Drug Court Enrollees: Results from A Pilot Study

Background:

Drug court interventions produce positive results—especially among mandated populations. Many criminal justice-involved persons, including drug court enrollees, have cooccurring substance abuse and childhood trauma disorders associated with psychological dysfunction. Given the coercive nature of mandated drug court treatment, it is important to understand whether childhood trauma and psychological functioning influence perceived coercion to enter treatment.

Objectives:

The purpose of this study was to describe the degree to which adverse childhood trauma and psychological functioning were associated with six domains of perceived coercion— self, family, legal, financial, health, and work—among a population of drug court enrollees.

Methods:

Data from 54 enrollees in a drug court pilot study were used to examine the relationship between childhood trauma, psychological functioning, and perceived coercion.

Results:

The pilot study data showed that psychological dysfunction and traumatic experiences in childhood were associated with higher perceived coercion to treatment, explaining 29% of the variance in coercion, controlling for gender and pre-arrest alcohol and drug use. Results indicated that the associations between psychological dysfunction and trauma were driven by non-legal types of coercion. In particular, childhood trauma was correlated with family (r = .32), financial (r = .32), and health (r = .47) types of coercion.

Conclusions:

Based on these preliminary findings, drug court practitioners are urged to assess perceived coercion, in addition to the behavioral health and childhood trauma of their clients, and to utilize non-legal types of coercion such as family, health, and financial impact to enhance treatment engagement.

Examining the validity of the adapted Alabama Parenting Questionnaire-Parent Global Report Version

The purpose of the present study was to comprehensively examine the validity of an adapted version of the parent global report form of the Alabama Parenting Questionnaire (APQ) with respect to its factor structure, relationships with demographic and response style covariates, and differential item functioning (DIF). The APQ was adapted by omitting the corporal punishment and the other discipline items. The sample consisted of 674 Canadian and United States families having a 9- to 12-year-old child and at least 1 parent figure who had received treatment within the past 5 years for alcohol problems or met criteria for alcohol abuse or dependence. The primary parent in each family completed the APQ. The 4-factor CFA model of the 4 published scales used and the 3-factor CFA model of those scales from prior research were rejected. Exploratory structural equation modeling was then used. The final 3-factor model combined the author-defined Involvement and Positive Parenting scales and retained the original Poor Monitoring/Supervision and Inconsistent Discipline scales. However, there were substantial numbers of moderate magnitude cross-loadings and large magnitude residual covariances. Differential item functioning (DIF) was observed for a number of APQ items. Controlling for DIF, response style and demographic variables were related significantly to the factors. (PsycINFO Database Record

Attrition in drug court research: Examining participant characteristics and recommendations for follow-up

Drug court research is often challenged by study attrition. In this study, researchers attempted to predict study completion using variables traditionally associated with treatment attrition. Findings showed that participants who reported a need for additional help to resolve legal problems and who reported accessing outpatient treatments were more likely to complete the study at the three-month follow-up. The study also demonstrated a relationship between trauma-related symptoms and study attrition. Although sample size was a limitation with these pilot data, researchers are urged to examine attrition and increase efforts to engage drug court enrollees in research studies, especially those with trauma-related symptoms.

Alcohol intake over the life course and breast cancer survival in Western New York exposures and breast cancer (WEB) study: quantity and intensity of intake

Alcohol intake is a risk factor for breast cancer, but the association between alcohol and mortality among breast cancer survivors is poorly understood. We examined the association between alcohol intake from all sources, assessed by cognitive lifetime drinking history, and all-cause and breast cancer mortality among women with breast cancer (N = 1,097) who participated in a population-based case-control study. Vital status was ascertained through 2006 using the National Death Index. Using Cox proportional hazards models, we computed hazard ratios for all-cause and breast cancer mortality in association with alcohol intake. We examined lifetime volume and intensity (drinks per drinking day) of alcohol consumption as well as drinking status during various life periods. Analyses were stratified by menopausal status. After adjustment for total intake, postmenopausal women with consumption of four or more drinks per drinking day over their lifetimes were nearly three times more likely to die from any cause compared to abstainers (HR 2.94, 95 % CI 1.31, 6.62). There was a similar but non-significant association with breast cancer mortality (HR 2.68, 95 % CI 0.94, 7.67). Postmenopausal women who drank one drink or fewer per drinking day between menarche and first birth had a significantly decreased hazard of all-cause (HR 0.54, 95 % CI 0.31, 0.95) and breast cancer mortality (HR 0.27, 95 % CI 0.09, 0.77). Premenopausal breast cancer survival was not associated with drinking intensity. We observed no associations between drinking status or total volume of alcohol intake and breast cancer or all-cause mortality. High-intensity alcohol consumption may be associated with decreased survival in postmenopausal women with breast cancer. Low-intensity alcohol consumption between menarche and first birth may be inversely associated with all-cause and breast cancer mortality; this period may be critical for development of and survival from breast cancer. Intensity of alcohol intake may be a more important factor than absolute volume of intake on survival in women with breast cancer.

Evidence from regression-discontinuity analyses for beneficial effects of a criterion-based increase in alcohol treatment

Brief interventions effectively reduce alcohol problems; however, it is controversial whether longer interventions result in greater improvement. This study aims to determine whether an increase in treatment for people with more severe problems resulted in better outcome. We employed regression-discontinuity analyses to determine if drinking driver clients (n = 22,277) in Ontario benefited when they were assigned to a longer treatment program (8-hour versus 16-hour) based on assessed addiction severity criteria. Assignment to the longer16-hour program was based on two addiction severity measures derived from the Research Institute on Addictions Self-inventory (RIASI) (meeting criteria for assignment based on either the total RIASI score or the score on the recidivism subscale). The main outcome measure was self-reported number of days of alcohol use during the 90 days preceding the six month follow-up interview. We found significant reductions of one or two self-reported drinking days at the point of assignment, depending on the severity criterion used. These data suggest that more intensive treatment for alcohol problems may improve results for individuals with more severe problems.

Child sexual abuse survivors with dissociative amnesia: what's the difference?

Although the issue of dissociative amnesia in adult survivors of child sexual abuse has been contentious, many research studies have shown that there is a subset of child sexual abuse survivors who have forgotten their abuse and later remembered it. Child sexual abuse survivors with dissociative amnesia histories have different formative and therapeutic issues than survivors of child sexual abuse who have had continuous memory of their abuse. This article first discusses those differences in terms of the moderating risk factors for developing dissociative amnesia (e.g., age, ethnicity, gender, etc.) and then mediating risk factors (e.g., social support, trait dissociativity, etc.). The differences between the two types of survivors are then explored in terms of treatment issues.

Depression, Readiness for Change, and Treatment Among Court-Mandated DUI Offenders

OBJECTIVE

The current study is part of a larger study that was designed to evaluate the impact of brief interventions on subsequent alcohol and drug use of individuals convicted of driving under the influence (DUI). This element considers the interaction of depression levels with treatment on subsequent substance use and problems related to substance use.

METHODS

Subjects were referred to the Research Institute on Addictions from various courts in the Western New York area for clinical evaluation and treatment referral, if further treatment was indicated. A total of 765 individuals were referred to the program, with 549 agreeing to participate. Participants were assessed at baseline using a number of different measures, with depression and readiness to change among them. A follow-up assessment took place 18-24 months following the baseline, with subsequent treatment experiences being one of the primary measures of interest for this study. A total of 443 participants were successfully interviewed at follow-up.

RESULTS

The high depression group had greater readiness to change and a greater likelihood of entering treatment than the low depression group (p's < .001). ANCOVAs showed depression by treatment interactions for drug problem severity, drug use, DUI risk, alcohol expectancies, abstinence self-efficacy, and psychiatric distress (all p's < .05). Furthermore, the treated high depression group made the largest positive gains across all outcomes (all p's < .01).

CONCLUSIONS

The readiness to change, treatment entry, and ANCOVA results, all support Wells-Parker and her colleagues' approach that depression may be a strong indicator of DUI offenders' readiness to change their substance use behavior.

An exploratory analysis of intimate partner violence and postpartum depression in an impoverished urban population

Research on the relationship between intimate partner violence (IPV) and postpartum depression (PPD) is limited. Numerous antecedents and consequences of both IPV and PPD are noted in the literature; however, understanding the mechanisms by which intimate partner violence impacts the postpartum mood are not clearly understood. This study utilized retrospective chart reviews from a pediatric/perinatal social work outreach program to explore urban minority women experiences with IPV and depression both during pregnancy and after. Findings do not suggest a direct relationship between IPV and PPD; however, there was a high co-occurrence of prenatal depression and PPD. The severity of IPV appears to influence the occurrence and acuity of prenatal depression suggesting an indirect relationship. Implications for health and social work practitioners are discussed.

Alcohol consumption in relation to aberrant DNA methylation in breast tumors

The mechanism for the observed association of alcohol consumption breast cancer risk is not known; understanding that mechanism could improve understanding of breast carcinogenesis and optimize prevention strategies. Alcohol may impact breast malignancies or tumor progression by altering DNA methylation. We examined promoter methylation of three genes, the E-cadherin, p16, and retinoic acid-binding receptor-β2 (RAR-β2) genes in archived breast tumor tissues from participants in a population-based case-control study. Real time methylation-specific PCR was performed on 803 paraffin-embedded samples, and lifetime alcohol consumption was queried. Unordered polytomous and unconditional logistic regression were used to derive adjusted odds ratios (ORs) and 95% confidence intervals (CIs). RAR-β2 methylation was not associated with drinking. Among premenopausal women, alcohol consumption was also not associated with promoter methylation for E-cadherin and p16 genes. In case-case comparisons of postmenopausal breast cancer, compared with lifetime never drinkers, promoter methylation likelihood was increased for higher alcohol intake for E-cadherin (OR=2.39; 95% CI, 1.15-4.96), in particular for those with estrogen receptor-negative tumors (OR=4.13; 95% CI, 1.16-14.72), and decreased for p16 (OR=0.52; 95% CI, 0.29-0.92). There were indications that the association with p16 was stronger for drinking at younger ages. Methylation was also associated with drinking intensity independent of total consumption for both genes. We found alcohol consumption was associated with DNA methylation in postmenopausal breast tumors, suggesting that the association of alcohol and breast cancer may be related, at least in part, to altered methylation, and may differ by drinking pattern.

Dental students' attitudes about older adults: do type and amount of contact make a difference?

This study was an extension of a previous study that considered dental student attitudes about older adults. In the current study, the association of student interactions with older adults, in both the dental school clinic and daily life, with their attitudes about this group was evaluated using the Aging Semantic Differential. A total of 311 dental students across all four years of academic standing were included in the study. The results showed that students' interactions with older adults outside the clinic did not relate to positive attitudes; however, even after controlling for the age of the student and the frequency, type of individual, and context of interactions with older adults outside the dental clinic, the number of older adult patients seen in the clinic showed a significant positive relationship with attitudes towards older adults. These results reinforce the conclusions drawn in a previous study that dental students' general attitudes about older adults may be changed, but that it is the exposure to older adults in a clinical setting that seems to be more critical in shaping these attitudes.

Delinquency and alcohol-impaired driving among young males: A longitudinal study

The present study assessed how the trajectory of delinquency affects the growth curve of alcohol-impaired driving using three-waves of data collected from the Buffalo Longitudinal Survey of Young Men (BLSYM). Using the structural equation modeling method, latent growth modeling was utilized to assess four age cohorts of sixteen, seventeen, eighteen, and nineteen years of age at the first wave. The data indicated that the growth rate of delinquency significantly and positively affects the growth rate of alcohol-impaired driving for the respondents who were sixteen at the first wave. The growth rate of drinking was also significantly and positively associated with the growth rate of alcohol-impaired driving for this age cohort. Although the growth rate of delinquency had no significant effect on the growth rate of alcohol-impaired driving for the age cohort which was seventeen at Wave 1, the growth rates of both drinking and drug use did affect for this age cohort. The data, however, showed that alcohol-impaired driving had a significant increase across the waves for the eighteen year old cohort, but there was no significant variation in the rate across respondents. Finally, for the nineteen year old cohort there was no significant increase in alcohol-impaired driving across the waves, and also no significant variation of the growth rate of alcohol-impaired driving across the respondents. These findings indicated that interventions focused on reducing delinquency, alcohol and drug use by sixteen and seventeen year old male adolescents will also reduce their alcohol-impaired driving.

Alcohol consumption and breast tumor mitochondrial DNA mutations

Mitochondrial DNA (mtDNA) mutations are frequent in breast tumors, but the etiology of these mutations is unknown. We hypothesized that these mutations are associated with exposures that affect oxidative stress such as alcohol metabolism. Using archived tumor blocks from incident breast cancer cases in a case control study, the Western New York Exposures and Breast Cancer (WEB) study, analysis of mtDNA mutations was conducted on 128 breast cancer cases selected based on extremes of alcohol intake. Temporal temperature gradient gel electrophoresis (TTGE) was used to screen the entire mtDNA genome and sequencing was completed for all TTGE positive samples. Case-case comparisons were completed using unconditional logistic regression to determine the relative prevalence of the mutations by exposures including alcohol consumption, manganese superoxide dismutase (MnSOD) genotype, nutrient intake related to oxidative stress and established breast cancer risk factors. Somatic mtDNA mutations were found in 60 of the 128 tumors examined. There were no differences in the prevalence of mtDNA mutations by alcohol consumption, MnSOD genotype or dietary intake. The likelihood of mtDNA mutations was reduced among those with a positive family history for breast cancer (OR = 0.33, CI = 0.12-0.92), among postmenopausal women who used hormone replacement therapy (OR = 0.46, CI = 0.19-1.08, P = 0.08) and was increased for ER negative tumors (OR = 2.05, CI = 0.95-4.43, P = 0.07). Consistent with previous studies, we found that mtDNA mutations are a frequent occurrence in breast tumors. An understanding of the etiology of mtDNA mutations may provide insight into breast carcinogenesis.

Examining factors in the Research Institute on Addictions Self-Inventory (RIASI): Associations with alcohol use and problems at assessment and follow-up

Impaired driving is a leading cause of alcohol-related deaths and injuries. Rehabilitation or remedial programs, involving assessment and screening of convicted impaired drivers to determine problem severity and appropriate programs, are an important component of society's response to this problem. Ontario's remedial program, Back on Track (BOT), involves an assessment process that includes administration of the Research Institute on Addictions Self-Inventory (RIASI) to determine assignment to an education or treatment program. The purpose of this study is to identify factors within the RIASI and examine how factor scores are associated with alcohol use and problem indicators at assessment and six-month follow-up. The sample included 22,298 individuals who completed BOT from 2000 to 2005. Principal component factor analysis with varimax rotation was conducted on RIASI data and an eight factor solution was retained: (1) Negative Affect, (2) Sensation Seeking, (3) Alcohol-Quantity, (4) Social Conformity, (5) High Risk Lifestyle, (6) Alcohol Problems, (7) Interpersonal Competence, and (8) Family History. Regression analyses were conducted to examine associations between factors and alcohol and problem measures obtained at assessment and at follow-up. Most factors, except for Interpersonal Competence, were associated with more alcohol use and problems at assessment. A similar pattern was observed at 6-month follow-up, but interestingly some factors (Negative Affect, Sensation Seeking, Alcohol-Quantity and Family History) predicted fewer days of alcohol use. The Interpersonal Competence factor was associated with significantly lower levels of alcohol use and problems at both assessment and follow-up. This work suggests that the RIASI provides information on several domains that have important relationships with alcohol problem severity and outcomes.

Alcohol consumption and genetic variation in methylenetetrahydrofolate reductase and 5-methyltetrahydrofolate-homocysteine methyltransferase in relation to breast cancer risk

It has been hypothesized that effects of alcohol consumption on one-carbon metabolism may explain, in part, the association of alcohol consumption with breast cancer risk. The methylenetetrahydrofolate reductase (MTHFR) and 5-methyltetrahydrofolate-homocysteine methyltransferase (MTR) genes express key enzymes in this pathway. We investigated the association of polymorphisms in MTHFR (rs1801133 and rs1801131) and MTR (rs1805087) with breast cancer risk and their interaction with alcohol consumption in a case-control study--the Western New York Exposures and Breast Cancer study. Cases (n = 1,063) were women with primary, incident breast cancer and controls (n = 1,890) were frequency matched to cases on age and race. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated by unconditional logistic regression. We found no association of MTHFR or MTR genotype with risk of breast cancer. In the original case-control study, there was a nonsignificant increased odds of breast cancer among women with higher lifetime drinking. In the current study, there was no evidence of an interaction of genotype and alcohol in premenopausal women. However, among postmenopausal women, there was an increase in breast cancer risk for women who were homozygote TT for MTHFR C677T and had high lifetime alcohol intake (>or=1,161.84 oz; OR, 1.92; 95% CI, 1.13-3.28) and for those who had a high number of drinks per drinking day (>1.91 drinks/day; OR, 1.80; 95% CI, 1.03-3.28) compared with nondrinkers who were homozygote CC. Our findings indicate that among postmenopausal women, increased breast cancer risk with alcohol consumption may be as a result of effects on one-carbon metabolism.

Relations among alcohol consumption measures derived from the Cognitive Lifetime Drinking History

Few studies have been conducted of chronic alcohol effects on health and social outcomes. To evaluate the utility and feasibility of such studies, correlations between lifetime and current measures of total alcohol consumption (ounces) and times intoxicated were examined to determine whether these dimensions of drinking are distinct. Studies were conducted in 2142 respondents ages 35 to 70 selected from lists of licensed drivers and individuals eligible for Medicare. Lifetime measures of alcohol consumption and times intoxicated were derived from the Cognitive Lifetime Drinking History (CLDH). Depending on age and sex of the subgroups examined, current consumption accounted for only about 10-25% of the variability in lifetime alcohol consumption; current and lifetime times intoxicated were even less highly correlated. Lifetime and current measures of alcohol consumption accounted for approximately 40-50% of the variability in corresponding lifetime and current measures of times intoxicated in younger cohorts, but this fell to 25% and less in older cohorts. These findings support the use of lifetime measures of alcohol consumption and times intoxicated based on the CLDH together with current measures to investigate chronic and acute alcohol effects on health and social outcomes.

Risky sexual behavior, bleeding caused by intimate partner violence, and hepatitis C virus infection in patients of a sexually transmitted disease clinic

OBJECTIVES

We sought to investigate independent contributions of risky sexual behaviors and bleeding caused by intimate partner violence to prediction of HCV infection.

METHODS

We conducted a case-control study of risk factors among patients of a sexually transmitted disease clinic with and without HCV antibodies, group-matched by age.

RESULTS

Multivariate analyses indicated that Black race (odds ratio [OR] = 2.4; 95% confidence interval [CI] = 1.3, 4.4), injection drug use (OR = 20.3; 95% CI = 10.8, 37.8), sharing straws to snort drugs (OR = 1.8; 95% CI = 1.01, 3.0), sharing razors (OR = 7.8; 95% CI = 2.0, 31.0), and exposure to bleeding caused by intimate partner violence (OR = 5.5; 95% CI = 1.4, 22.8) contributed significantly to the prediction of HCV infection; risky sexual behavior and exposure to blood or sores during sexual intercourse did not.

CONCLUSIONS

HCV risk among patients of a sexually transmitted disease clinic can be explained by direct blood exposure, primarily through injection drug use. Exposure to bleeding caused by intimate partner violence may be a previously unrecognized mechanism for HCV transmission associated with risky sexual behavior.

Factors that influence dental students' attitudes about older adults

Our study considered dental students' general attitudes towards older persons using the Aging Semantic Differential. The influence of age, gender, cohort, education, and academic exposure on general attitudes towards older adults was evaluated using a total of 328 dental students across all four years of academic standing. Students were assessed in the fall and spring semesters. The results showed differential responding on the four subscales, with slight positive ratings on the autonomy, acceptability, and integrity subscales and a slight negative rating for instrumentality. Females expressed more negative attitudes than their male counterparts, with no age differences. There was also no significant impact from a specific, didactic educational component offered to the fourth-year students. However, the fourth-year students were the only group to show positive changes across the full academic year. The results suggest that general attitudes can be changed, but didactic (classroom) forms of education alone are insufficient to meaningfully modify students' perceptions of the elderly. Exposure to older adults in a clinical setting appears to be a critical element, as the fourth-year students received much greater exposure to older patients and more intensified interface with their mentors.

Compliance and learning in an intervention program for partner-violent men

Although research has yielded mixed findings regarding the effectiveness of intervention programs for partner-violent men, it appears that greater participant compliance with such programs is associated with better outcomes. However, no research to date has jointly examined compliance with intervention programs and the extent to which partner-violent men learn specific information presented during the programs. The current study makes use of existing data to evaluate general and specific elements of partner-violent men's compliance with (i.e., active, appropriate participation in) an intervention program and recall of key points from the program. Results from a subsample of 22 men indicate that at program termination, those rated as having been "process conscious" during intervention group sessions, having self-disclosed during sessions, having evidenced awareness and use of techniques to avoid violence, and having used respectful language show greater recall of material taught in the program. This finding points to the potential benefit of taking steps to increase men's active participation in programs and of studying active engagement as a mediator of program effects on men's violence toward partners.

Mental health among suburban drug court participants

The issue of co-occurring disorders is of concern to the Criminal Justice field, including drug courts. To assess the potential co-occurrence of substance use- and mental health-related diagnoses, the Psychiatric Diagnostic Screening Questionnaire and similar instruments was administered to suburban drug court clients. Based on the screening, one quarter to one half of the 108 participants would be referred for follow-up for a mental health issue; women would be referred at a greater rate than men. There is a need to develop appropriate, brief mental health screening instruments for use in drug court settings so that clients can receive necessary services.

Alcohol drinking pattern and non-fatal myocardial infarction in women

AIMS

Evidence continues to emerge indicating the pattern of alcohol consumption has important implications for cardiovascular disease (CVD) risk, although the majority of studies have focused on men. The aim of the study is to examine the association between alcohol volume and various drinking patterns and non-fatal myocardial infarction (MI) in women aged 35-69 years.

DESIGN AND SETTING

Population-based case-control study, 1996-2001.

PARTICIPANTS

Incident MI cases (n = 320) recruited from Western NY hospitals, controls (n = 1565) identified from motor vehicle rolls and Health Care Financing Administration (HCFA) files.

MEASUREMENTS

Incident MI, volume and drinking patterns for the 12-24 months prior to interview (controls) or MI (cases) were assessed in detail.

FINDINGS

Of cases and controls, 13% were life-time abstainers; current drinkers averaged 2.3 +/- 2.2 drinks/drinking day. Compared to life-time abstainers, current drinkers tended to have a reduced likelihood of MI [odds ratio (OR), 0.67; 95% confidence interval (CI), 0.43-1.03]. Volume, drinks/drinking day and frequency were associated inversely with MI risk (P trends < 0.001). Wine drinkers (OR, 0.56; 95% CI, 0.33-0.96) and consumers of mixed beverage types (OR, 0.56, 0.31-1.01) had lower odds of MI compared to abstainers. Among current drinkers, for volume and most patterns, similar but somewhat weaker associations were noted than when abstainers were the reference. In contrast, frequency of intoxication at least once/month or more was associated with a strong increased risk compared to abstention (OR, 2.90; 95% CI 1.01-8.29) or in current drinkers, never drinking to this extent (OR, 6.22; 95% CI 2.07-18.69).

CONCLUSION

In this population of light to moderate drinkers, alcohol consumption in general was associated with decreased MI risk in women; however, episodic intoxication was related to a substantial increase in risk.

Alcohol drinking pattern and subjective health in a population-based study

AIMS

Some patterns of alcohol consumption (e.g. binge drinking, drinking outside of meals) have been associated with detrimental effects on health outcomes. Subjective health provides a global assessment of health status and is a strong predictor of total mortality; however, little is known about its relationship with alcohol drinking pattern. The association between several drinking patterns (i.e. drinking intensity and frequency, frequency of intoxication, drinking outside of meals, and beverage type) and subjective health was examined in a random sample of 3586 women and men.

DESIGN

A population-based cross-sectional study.

METHODS

Subjective health was assessed using the physical and mental health component summaries of the Short Form-36 health survey questionnaire. Alcohol consumption refers to the 30 days before the interview. Analysis of covariance compared gender-specific mean scores across alcohol drinking patterns.

FINDINGS

Overall, non-current drinkers reported poorer physical and mental health than life-time abstainers and current drinkers, while no consistent differences were found between life-time abstainers and current drinkers. In female current drinkers, daily drinking, beer and mixed beverage consumption were associated with better mental health. In male current drinkers, moderate alcohol consumption (2-2.9 drinks per day), wine and mixed beverage consumption were associated with better physical health. Intoxication and liquor consumption were associated with poorer mental health in women and poorer physical health in men. No consistent associations were found for drinking outside meals.

CONCLUSIONS

Aspects of drinking pattern may affect subjective health differentially in women and men. Overall, intoxication and liquor drinking are associated with poorer self-perceived health status than regular, moderate consumption of other alcoholic beverages.

Relapse to driving under the influence (DUI): A review

Driving under the influence (DUI) is a major public health problem. In 2003, there were 17,401 alcohol-related crash fatalities. Although there has been a large decrease in the fatality rates over the past two decades, further progress has stalled in recent years. This plateau in the injury and death rates resulting from impaired driving has been attributed, in part, to the persistent or repeat DUI offender. Broadly defined, repeat offenders are those individuals who, following an initial DUI arrest, relapse to driving under the influence of alcohol and other drugs. In this paper, we first provide a brief overview of several models of DUI relapse. We then review the empirical literature on DUI relapse, the data describing characteristics of first-time and repeat DUI offenders, and, especially, studies that have evaluated the impact of legal sanctions and rehabilitation programs on subsequent DUI behavior. The data reveal that DUI offenders are a heterogeneous group, and that simple models relying on only one or two behavioral domains (e.g., driving characteristics, demographics) to explain DUI relapse are insufficient to account for the DUI behavior of offenders. To advance our understanding of DUI relapse, we argue for development and testing of multifactorial models focusing on the interplay of legal, social and psychological factors that describe and explain relapse among DUI offenders. By recognizing the heterogeneity within the offender population it will be easier for researchers and clinicians to identify subgroups that are at high-risk for relapse and which should be targeted by prevention and intervention programs.

More than a set of teeth: assessing and enhancing dental students' perceptions of older adults

Dental professionals play a key role in maintaining the well-being of older adults by identifying problems that disturb systemic health. A 3-part instrument was used to assess dental students' knowledge of aging, comfort with patient diversity and patient care strategies (Years 1-4; N = 321). Collaborative education and services were developed by the Schools of Dental Medicine and Social Work. Results indicate that dental students' knowledge of aging was low (Palmore's FAQ 1 Range = 58%-64%), comfort with geriatric issues improved after the first year of intervention, and strategies for patient care changed with experience. Group differences suggest the importance of utilizing educational "turning points" as teachable moments.

Understanding dental students' knowledge and perceptions of older people: toward a new model of geriatric dental education

Increasing numbers of older people and the decreasing rates of edentulism highlight the importance of dental education that focuses on oral health and aging. This evaluation study assessed dental students' knowledge and beliefs about older people as well as their awareness of the biopsychosocial concerns that are potential barriers to oral health care. Dental students' (N=202) knowledge and perceptions of older people were evaluated before and after the first year of a new educational program. Students completed the Palmore Facts on Aging Quiz II (FAQ II) and answered questions about health problems and social concerns that may influence patient care. The intervention was twofold: 1) the CARES (Counseling, Advocacy, Referral, Education, and Service) Program, a clinical collaboration between the schools of Dental Medicine and Social Work, was initiated; and 2) all students were exposed to geriatric educational interventions. FAQ II scores did not significantly change, but dental students' awareness of mental health, independence, and social concerns increased between Times 1 and 2. The results of the study suggest that positive interactions with older adults by health care providers may depend more on positive perceptions toward older people than increased knowledge about aging. Future research will focus on positive experiences with older adults and attitudes of dental students toward the elderly.

Relationship of Alcohol Drinking Pattern to Risk of Hypertension

Epidemiological studies have demonstrated a positive relationship between heavy alcohol use and hypertension, but few studies have directly addressed the role of drinking pattern. This study was designed to investigate the association of current alcohol consumption and aspects of drinking pattern with hypertension risk in a sample of 2609 white men and women from western New York, aged 35 to 80 years, and free from other cardiovascular diseases. Hypertension was defined by systolic blood pressure > or =140 mm Hg or diastolic blood pressure > or =90 mm Hg or use of antihypertensive medication. Odds ratios (95% confidence intervals) were computed after adjustment for several covariates. Compared with lifetime abstainers, participants reporting drinking on a daily basis (1.75 [1.13 to 2.72]) or mostly without food (1.64 [1.08 to 2.51]) exhibited significantly higher risk of hypertension. When analyses were restricted to current drinkers, daily drinkers and participants consuming alcohol without food exhibited a significantly higher risk of hypertension compared with those drinking less than weekly (1.65 [1.18 to 2.30]) and those drinking mostly with food (1.49 [1.10 to 2.00]), respectively. After additional adjustment for the amount of alcohol consumed in the past 30 days, the results were follows: 0.90 (0.58 to 1.41) for daily drinkers and 1.41 (1.04 to 1.91) for drinkers without food. For predominant beverage preference, no consistent association with hypertension risk was found across the various types of beverages considered (beer, wine, and liquor). In conclusion, drinking outside meals appears to have a significant effect on hypertension risk independent of the amount of alcohol consumed.
