When the Caregiver Needs Care: The Plight of Vulnerable Caregivers

OBJECTIVES This study examined the characteristics, activities, and challenges of high-risk informal caregivers. METHODS Telephone interviews were conducted with a nationally representative cross-section of 1002 informal caregivers. Vulnerable caregivers with poor health or a serious health condition were compared with nonvulnerable caregivers. RESULTS Thirty-six percent of caregivers were vulnerable. Compared with nonvulnerable caregivers, vulnerable caregivers were more likely to have difficulty providing care, to provide higher-intensity care, to report that their physical health had suffered since becoming a caregiver, to be aged 65 years or older, to be married, and to have less than 12 years of education. CONCLUSIONS Reliance on informal caregivers without considering the caregivers ability to provide care can create a stressful and potentially unsafe environment for the caregiver and the care recipient.

Substance Abuse Among Older Adults

Although the myth that older adults do not use mood-altering substances persists, evidence suggests that substance use among older adults has been underidentified for decades. The baby boom generation is unique in its exposure to, attitudes toward, and prevalence of substance use-causing projected rates of substance use to increase over the next twenty years. Given their unique biological vulnerabilities and life stage, older adults who misuse substances require special attention. Prevalence rates of substance use and misuse among older adults, methods of screening and assessment unique to older adults, and treatment options for older adults are reviewed.

The impact of retirement on the drinking patterns of older adults: A review

OBJECTIVE Due to the aging of the population, there is renewed focus on the public health issues of middle-aged and older adults. One area of such focus is unhealthy drinking, and researchers seek to understand the unique developmental risk and protective factors among those entering older adulthood. Retirement has been hypothesized as a contributing factor in the onset and maintenance of unhealthy drinking in late life. This review describes the relevant theories and critically reviews empirical evidence that explores the relationship between alcohol and retirement drawn from both the industrial and organizational psychology and substance misuse literatures. METHOD Using four research databases, thirteen studies published in the last 25years that investigated the relationship of retirement and alcohol use and met specific selection criteria were reviewed. RESULTS The literature suggests that retirement may not have a strong direct impact on drinking behaviors or problems, but attributes of the process (e.g. retirement voluntariness) of transition to retirement and individual attributes, such as having a history of problem drinking, may facilitate or inhibit drinking. CONCLUSIONS Future research should delve into the social context of drinking in retirement with a goal of understanding the aspects and conditions of retirement that increase risk of alcohol problems. Investigation should also examine heterogeneity in retirement drinking patterns with a goal of identifying subpopulations that are at greater risk.

Motivational Interviewing: A Pilot Test of Active Ingredients and Mechanisms of Change

Motivational interviewing (MI) is an effective treatment for substance use disorders (SUDs) that focuses on resolving ambivalence and increasing commitment to positive behavior change. Although MI has a well-developed clinical theory, research findings have been mixed in supporting its view of how change occurs. The primary aim of this pilot study was to test hypothesized MI active ingredients and mechanisms of change in reducing drinking during the initiation of a behavior change episode. Problem drinkers (N = 89) seeking treatment were randomly assigned to MI, relational MI without directive elements (spirit-only MI [SOMI]), or a self-change (SC) control condition. Participants were followed during an 8-week treatment period. The first 2 of 4 treatment sessions were videotaped and coded for fidelity, discriminability, and change talk. Overall, conditions demonstrated high fidelity. As predicted, change talk significantly increased in MI relative to the SOMI condition. Drinking was significantly reduced at end treatment, but the reduction was equivalent across conditions. Post hoc analyses found that MI reduced drinking more rapidly than SOMI and SC and that increased change talk mediated the effects of MI relative to SOMI during the week immediately following the first session. Findings are discussed in the context of the pilot nature of the study and the relative absence of experimental tests of mechanisms of behavior change in SUD treatment research.

Developing a theory driven text messaging intervention for addiction care with user driven content.

The number of text messaging interventions designed to initiate and support behavioral health changes have been steadily increasing over the past 5 years. Messaging interventions can be tailored and adapted to an individuals needs in their natural environment-fostering just-in-time therapies and making them a logical intervention for addiction continuing care. This study assessed the acceptability of using text messaging for substance abuse continuing care and the intervention preferences of individuals in substance abuse treatment in order to develop an interactive mobile text messaging intervention. Fifty individuals enrolled in intensive outpatient substance abuse treatment completed an assessment battery relating to preferred logistics of mobile interventions, behavior change strategies, and types of messages they thought would be most helpful to them at different time points. Results indicated that 98% participants were potentially interested in using text messaging as a continuing care strategy. Participants wrote different types of messages that they perceived might be most helpful, based on various hypothetical situations often encountered during the recovery process. Although individuals tended to prefer benefit driven over consequence driven messages, differences in the perceived benefits of change among individuals predicted message preference. Implications for the development of mobile messaging interventions for the addictions are discussed. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

A Review of Existing Treatments for Substance Abuse Among the Elderly and Recommendations for Future Directions

Background With population aging, there is widespread recognition that the healthcare system must be prepared to serve the unique needs of substance using older adults (OA) in the decades ahead. As such, there is an increasingly urgent need to identify efficient and effective substance abuse treatments (SAT) for OA. Despite this need, there remains a surprising dearth of research on treatment for OA. Aims of review This review describes and evaluates studies on SAT applied to and specifically designed for OA over the last 30 years with an emphasis on methodologies used and the knowledge gained. Methods Using three research databases, 25 studies published in the last 30 years which investigated the impact of SAT on OA and met specific selection criteria were reviewed. Results A majority of the studies were methodologically limited in that they were pre-to-post or post-test only studies. Of the randomized controlled trials, many were limited by sample sizes of 15 individuals or less per group, making main effects difficult to detect. Thus, with caution, the literature suggests that among treatment seeking OA, treatment, whether age-specific or mixed-age, generally works yielding rates of abstinence comparable to general populations and younger cohorts. It also appears that with greater treatment exposure (higher dosage), regardless of level of care, OA do better. Finally, based on only two studies, age-specific treatment appears to potentiate treatment effects for OA. Like younger adults, OA appear to have a heterogeneous response to treatments, and preliminary evidence suggests a possibility of treatment matching for OA. Conclusions Expansion of research on SAT for OA is urgently needed for maximum effectiveness and efficiency of the healthcare system serving these individuals. Future research needs to include laboratory and community based randomized controlled trials with high internal validity of previously vetted evidenced-based practices, including Motivational Interviewing, cognitive behavioral therapy, and medications such as naltrexone, to determine the best fit for OA.

Improving 24-Month Abstinence and Employment Outcomes for Substance-Dependent Women Receiving Temporary Assistance for Needy Families With Intensive Case Management

OBJECTIVE We examined abstinence rates among substance-dependent women receiving Temporary Assistance for Needy Families (TANF) in intensive case management (ICM) over 24 months and whether ICM yielded significantly better employment outcomes compared with a screen-and-refer program (i.e., usual care). METHODS Substance-dependent (n = 302) and non-substance dependent (n = 150) TANF applicants in Essex County, New Jersey, were recruited. We randomly assigned substance-dependent women to ICM or usual care. We interviewed all women at 3, 9, 15, and 24 months. RESULTS Abstinence rates were higher for the ICM group than for the usual care group through 24 months of follow-up (odds ratio [OR] = 2.11; 95% confidence interval [CI] = 1.36, 3.29). A statistically significant interaction between time and group on number of days employed indicated that the rate of improvement over time in employment was greater for the ICM group than for the usual care group (incidence rate ratio = 1.03; 95% CI = 1.02, 1.04). Additionally, there were greater odds of being employed full time for those in the ICM group (OR = 1.68; 95% CI = 1.12, 2.51). CONCLUSIONS ICM is a promising intervention for managing substance dependence among women receiving TANF and for improving employment rates among this vulnerable population.

An Item Response Theory (IRT) analysis of the Short Inventory of Problems-Alcohol and Drugs (SIP-AD) among non-treatment seeking men-who-have-sex-with-men: Evidence for a shortened 10-item SIP-AD

The Short Inventory of Problems-Alcohol and Drugs (SIP-AD) is a 15-item measure that assesses concurrently negative consequences associated with alcohol and illicit drug use. Current psychometric evaluation has been limited to classical test theory (CTT) statistics, and it has not been validated among non-treatment seeking men-who-have-sex-with-men (MSM). Methods from Item Response Theory (IRT) can improve upon CTT by providing an in-depth analysis of how each item performs across the underlying latent trait that it is purported to measure. The present study examined the psychometric properties of the SIP-AD using methods from both IRT and CTT among a non-treatment seeking MSM sample (N=469). Participants were recruited from the New York City area and were asked to participate in a series of studies examining club drug use. Results indicated that five items on the SIP-AD demonstrated poor item misfit or significant differential item functioning (DIF) across race/ethnicity and HIV status. These five items were dropped and two-parameter IRT analyses were conducted on the remaining 10 items, which indicated a restricted range of item location parameters (-.15 to -.99) plotted at the lower end of the latent negative consequences severity continuum, and reasonably high discrimination parameters (1.30 to 2.22). Additional CTT statistics were compared between the original 15-item SIP-AD and the refined 10-item SIP-AD and suggest that the differences were negligible with the refined 10-item SIP-AD indicating a high degree of reliability and validity. Findings suggest the SIP-AD can be shortened to 10 items and appears to be a non-biased reliable and valid measure among non-treatment seeking MSM.

Drinking behavior among older adults at a continuing care retirement community: affective and motivational influences

Objectives: The purpose of this pilot study was to describe patterns of alcohol consumption among continuing care retirement community(CCRC) residents and to explore the role of drinking motives and affective states on drinking context and consumption. Method: We utilized a phone-based daily diary approach to survey older adults about their daily alcohol consumption, context of drinking (e.g. drinking alone), positive and negative affect, and their motives for drinking. Data were analyzed descriptively, and regression models were developed to examine associations between sociodemographic factors, affect, drinking context and motives, and alcohol consumption. Results: CCRC residents drank most frequently at home and were alone almost half of drinking days on average, although the context of drinking varied considerably by participant. Problem alcohol use was rare, but hazardous use due to specific comorbidities, symptoms and medications, and the amount of alcohol consumption was common. Respondents endorsed higher social motives for drinking and lower coping motives. Social motives were associated with decreased likelihood of drinking alone, but negative affect was associated with decreased likelihood of drinking outside ones home. Coping and social motives were associated with greater consumption, and higher positive affect was associated with lower consumption. Conclusion: Among CCRC residents, alcohol use may be socially motivated rather than motivated by coping with negative affect. Future research should examine other motives for drinking in older adulthood. Evaluation of older adults living in CCRCs should include attention to health factors beyond problem use as other forms of hazardous use may be common in CCRCs.

Functioning of Alcohol Use Disorders Criteria Among Middle-Aged and Older Adults: Implications for DSM-5

This study explored dimensionality and rank-order severity of the Diagnostic and Statistical Manual of Mental Disorders fourth edition (DSM-IV) alcohol use disorder (AUD) criteria among adults 50+ years old. Secondary analysis was performed on data from individuals 50+ (N = 3,412) from the 2009 National Survey of Drug Use and Health. Confirmatory factor analyses (CFA) and item response theory (IRT) analyses were performed on the 11 AUD criteria. DSM-IV and DSM fifth edition (DSM-5) classifications were compared. CFA revealed a one-factor model. IRT analyses revealed that AUD criteria identify only severe cases of AUD. Overall, 5.8% met criteria for a DSM-IV AUD; 7.5% met criteria for DSM-5 AUD.
