Functioning of alcohol use disorders criteria among middle-aged and older adults: implications for DSM-5

The Associations between Remission Status, Discounting Rates, and Recovery from Substance Use Disorders

Background: Recovery from substance use disorders (SUDs) requires sustained and purposeful support to maintain long-term remission. Methods: This study investigated the association between assessment of recovery capital, household chaos, delay discounting (DD) and probability discounting (PD), and remission status among individuals in recovery from SUD. Data from 281 participants from the International Quit & Recovery Registry (IQRR), an ongoing online registry that aims to study the recovery process, were included in the analysis. Results: Lower DD rates and higher recovery capital were found among those in remission compared to those not in remission after controlling for demographics. In contrast, the association of household chaos and PD with remission status were insignificant. Overall, DD accounted for 20% of the total effect between the recovery capital and the remission status. Conclusion: This study contributes to the understanding of recovery as a multidimensional process, supports DD as a behavioral marker of addiction, and suggests areas for future research.

Mental health care for older adults: recent advances and new directions in clinical practice and research

The world's population is aging, bringing about an ever-greater burden of mental disorders in older adults. Given multimorbidities, the mental health care of these people and their family caregivers is labor-intensive. At the same time, ageism is a big problem for older people, with and without mental disorders. Positive elements of aging, such as resilience, wisdom and prosocial behaviors, need to be highlighted and promoted, both to combat stigma and to help protect and improve mental health in older adults. The positive psychiatry of aging is not an oxymoron, but a scientific construct strongly informed by research evidence. We champion a broader concept of geriatric psychiatry - one that encompasses health as well as illness. In the present paper, we address these issues in the context of four disorders that are the greatest source of years lived with disability: neurocognitive disorders, major depression, schizophrenia, and substance use disorders. We emphasize the need for implementation of multidisciplinary team care, with comprehensive assessment, clinical management, intensive outreach, and coordination of mental, physical and social health services. We also underscore the need for further research into moderators and mediators of treatment response variability. Because optimal care of older adults with mental disorders is both patient-focused and family-centered, we call for further research into enhancing the well-being of family caregivers. To optimize both the safety and efficacy of pharmacotherapy, further attention to metabolic, cardiovascular and neurological tolerability is much needed, together with further development and testing of medications that reduce the risk for suicide. At the same time, we also address positive aging and normal cognitive aging, both as an antidote to ageism and as a catalyst for change in the way we think about aging per se and late-life mental disorders more specifically. It is in this context that we provide directions for future clinical care and research.

The Prognostic Role of DSM-5 Alcohol Use Disorder Severity and Age of Onset in Treatment Outcome Among Adults Aged 60

AIMS

To investigate among older adults with DSM-5 alcohol use disorder (AUD) the relevance of (1) baseline DSM-5 AUD severity, (2) age of DSM-5 AUD onset, and (3) the interactions of DSM-5 AUD severity*treatment condition and age of DSM-5 AUD onset*treatment condition for the prediction of AUD treatment outcomes.

METHODS

The international multicenter RCT "ELDERLY-Study" compared outpatient motivational enhancement therapy (4 sessions) with outpatient motivational enhancement therapy followed by community reinforcement approach for seniors (8 sessions) in adults aged 60+ with DSM-5 AUD. Baseline and 1-, 3-, and 6-month follow-up data from the German and Danish ELDERLY-sites (n = 544) were used (6-month participation rate: 75.9%). DSM-5 AUD diagnoses were obtained using the Mini International Neuropsychiatric Interview and alcohol use using Form 90. Associations between DSM-5 AUD severity and age of onset and AUD treatment outcomes were investigated using multiple logistic regression and generalized linear models.

RESULTS

The sample was diverse in AUD severity (severe: 54.9%, moderate: 28.2%, mild: 16.9%) and age of onset (median: 50 years; 12-78 years). Overall, with few exceptions, neither AUD severity, nor age of onset, nor their respective interactions with treatment condition significantly predicted drinking outcomes at the different follow-ups (P ≥ 0.05).

CONCLUSIONS

No indication was found for the need to tailor treatment content according to DSM-5 AUD severity and earlier onset in older adults.

Reliability of Differential Item Functioning in Alcohol Use Disorder: Bayesian Meta-Analysis of Criteria Discrimination Estimates

Numerous studies leverage item response theory (IRT) methods to examine measurement characteristics of alcohol use disorder (AUD) diagnostic criteria. Less work has examined the consistency of AUD IRT parameter estimates, an essential step for establishing measurement invariance, making statements about symptom diagnosticity, and validating the theoretical construct. A Bayesian meta-analysis of IRT discrimination values for AUD criteria across 33 independent samples (Total N = 321,998) revealed that overall consistency of AUD criteria discriminations was low (generalized intraclass correlation range = .105-.249). However, specific study characteristics accounted for substantial variability, suggesting that the unreliability is partially systematic. We replicated evidence of differential item functioning (DIF) via established factors (e.g., age, gender), but the magnitudes were small compared with DIF associated with assessment instrument. These results offer practical recommendations regarding which instruments to use when specific AUD criteria are of interest and which criteria are most sensitive when comparing demographic groups.

Age-related differences in the associations among at-risk drinking, alcohol use disorder, and psychological distress across the adult lifespan: a nationwide representative study in South Korea

PURPOSE

To investigate age-related differences in the relationships among at-risk alcohol consumption, alcohol use disorder (AUD), and psychological distress with a special focus on older adults.

METHODS

We used a nationwide cross-sectional study of a representative sample of community-dwelling adults from the Korean Epidemiologic Catchment Area study for psychiatric disorders conducted by door-to-door interviews. The Korean version of the Composite International Diagnostic Interview was applied. Subjects were categorized into four age groups: young-to-middle-aged (20-54 years), near-old (55-64 years), early-old (65-74 years), and late-old (≥ 75 years). The associations among at-risk drinking, alcohol use disorder, and psychological distress were examined according to age groups.

RESULTS

Among a total of 5102 individuals, half of them drank alcohol in the previous year, of whom 20.5% were at-risk drinkers (≥ 100 g/week). Older people were less often diagnosed with AUD than young-to-middle-aged adults with a similar degree of at-risk drinking. They were less likely to meet the DSM-5 AUD criteria in terms of social and vocational role disruption or creation of a physically hazardous situation. However, at-risk drinking showed a stronger association with subjective psychological distress in older adults, particularly in the near-old group (adjusted odds ratio 1.82, 95% confidence interval 1.09-3.03; p = 0.023).

CONCLUSIONS

These findings indicate the importance of screening for mental health problems in older adults, especially near-old adults, who drink more than 100 g of alcohol per week even when they do not satisfy the criteria for a diagnosis of AUD.

The Alcohol Dependence Scale and DSM-5 alcohol use disorder: Severity ratings correspond insufficiently in older patients

OBJECTIVES

To investigate the psychometric properties of the frequently used Alcohol Dependence Scale (ADS) in older adults and the associations between ADS scores and alcohol use and DSM-5 AUD symptom counts.

METHODS

Using baseline data from an international multicenter RCT on outpatient AUD treatment for adults aged 60+ with DSM-5 alcohol use disorder (AUD; n = 529), we computed Cronbach's alpha (α) and applied confirmatory (CFA) and exploratory factor analysis (EFA) to determine the underlying factor structure. A structural equation model (SEM) explored the interrelationship of latent ADS factors with alcohol use and number of DSM-5 criteria endorsed.

RESULTS

Internal consistency of the ADS (α = 0.81) was good. EFA revealed a three-factor structure. Factor 1 ("Severe withdrawal symptoms") consisted of severe psychoperceptual and psychophysical consequences of excessive drinking, Factor 2 ("Loss of control") consisted of acute physical reactions of intoxication, and Factor 3 ("Obsessive-compulsive drinking") described habitual drinking. The SEM suggested that only Factor 3 had large effects on DSM-5 symptom score and drinking behavior.

CONCLUSION

Lowering the ADS threshold or focusing on ADS items from Factor 3 may be more suitable measures of severity of alcohol dependence in treatment-seeking older adults as ADS scores are low and not closely related to DSM-5 AUD.

The effect of legal mandates on substance use disorder treatment completion among older adults

Objective: This study seeks to determine the relationship between referral type (legally mandated versus non-mandated) and substance use disorder (SUD) treatment completion among older adults and by primary substance used.Method: We used data from the Treatment Episode Data Set - Discharges (TEDS-D) from 2011. Using data for persons age 55 and over (n = 104,747), we used propensity score matching (PSM) to address selection bias and attenuate the likelihood of a type I error. Logistic regression models estimated the effect of referral type on treatment completion based on treatment for a primary substance for five categories of substances.Results: In the matched sample, those who faced treatment mandates had 71% greater odds of completing treatment compared with those who entered treatment voluntarily (OR =1.71, 95% CI [1.64, 1.79]). Based on the primary drug used, odds of treatment completion were highest for alcohol, with 86% greater treatment completion for the mandated individuals compared with those entering treatment without a legal mandate (OR =1.86, 95% CI [1.75, 1.97]).Conclusion: These findings suggest that the motivating influence of treatment mandates may encourage completion of SUD treatment among older adults. Although the legal mandates for treatment are punitive, they may act to keep older adults with SUD engaged in treatment, an important factor as treatment completion is inversely related to relapse of a SUD.

DSM-5 Latent Classes of Alcohol Users among Treatment Seeking Older Adults

Objective: Understanding the variation of alcohol use disorder (AUD) among a clinical sample of patients aged 60 and older, by identifying latent classes of AUD and exploring risk factors and outcomes of treatment associated with the class. Method: We used the Danish subsample (n = 341) from the Elderly Study. Latent class analysis was used to identify classes based on the 11 symptoms of DSM-5 AUD. We analyzed the associations between class membership and sociodemographic variables, alcohol consumption, and drinking-related outcome of treatment. Results: Three latent classes were identified. Individuals in the low-symptomatic class (34.85%) displayed low endorsement of DSM-5 criteria "Withdrawal", "Time Spent", "Less activities" compared to the other classes, and had fewest drinks per drinking day. Individuals in the moderate-symptomatic class (32.69%) were most likely to be intoxicated in hazardous situations, and those in the high-symptomatic class (32.47%) displayed, with a few exceptions, the highest probabilities of all DSM-5 criteria. Female gender, living alone and prior AUD treatment was associated with increased risk of being in the high-symptomatic class. No difference between classes was found with respect to years with AUD and frequency of drinking days, and latent class membership had no effect on drinking outcome after treatment, when controlling for baseline. Conclusions: Three classes of DSM-5 AUD among older adults in treatment emerged, displaying a low-moderate-high distribution, advocating for a unidimensional construct of DSM-5 AUD. Although different with respect to baseline risk factors, no strong connection between DSM-5 latent class and alcohol consumption after AUD treatment was found.HighlightsAmong 341 older alcohol use disorder (AUD) outpatients, three latent classes of DSM-5 AUD emerged.The classes of DSM-5 AUD displayed a low-moderate-high endorsement of DSM-5 AUD characteristics.The three classes had similar alcohol-related treatment outcomes.

The lingering effects of work context: Ambient work-unit characteristics and the impact of retirement on alcohol consumption

While it is well established that workplace demands and culture can affect employee well-being, to what degree might these same factors have lingering implications on individual wellbeing after employees retire? To begin to answer this question, in this paper we propose and test a model explaining how retiree alcohol consumption may depend on pre-retirement contextual conditions. Specifically, we propose and test a moderated-mediation model in which two ambient work unit characteristics-work-unit stress climate and work-unit drinking norms-moderate the indirect effects of retirement, via distress, on modal alcohol consumption (i.e., the typical quantity and frequency of alcohol consumed). Using a prospective study design and a multi-level, zero-inflated negative binomial model for predicting modal alcohol consumption, our findings lend partial support for the proposed model. We found retirement (vs. continued employment) to be associated with a heightened probability of being an abstainer after retirement eligibility (i.e., at Time 2), regardless of the hypothesized unit-level moderators. Still, retirement had mixed effects on the level of modal consumption among those not abstaining at Time 2, with these effects being partially mediated by distress and contingent upon unit-level stress climate and unit-level drinking norms.

DSM-5 alcohol use disorder features among treatment-seeking older adults

Abstract. Background: The number of older adults with alcohol use disorder (AUD) is expected to rise. Adapted treatments for this group are lacking and information on AUD features in treatment seeking older adults is scarce. The international multicenter randomized-controlled clinical trial “ELDERLY-Study” with few exclusion criteria was conducted to investigate two outpatient AUD-treatments for adults aged 60+ with DSM-5 AUD. Aims: To add to 1) basic methodological information on the ELDERLY-Study by providing information on AUD features in ELDERLY-participants taking into account country and gender, and 2) knowledge on AUD features in older adults seeking outpatient treatment. Methods: baseline data from the German and Danish ELDERLY-sites (n=544) were used. AUD diagnoses were obtained with the Mini International Neuropsychiatric Interview, alcohol use information with Form 90. Results: Lost control, desired control, mental/physical problem, and craving were the most prevalent (> 70 %) AUD-symptoms. 54.9 % reported severe DSM-5 AUD (moderate: 28.2 %, mild: 16.9 %). Mean daily alcohol use was 6.3 drinks at 12 grams ethanol each. 93.9 % reported binging. More intense alcohol use was associated with greater AUD-severity and male gender. Country effects showed for alcohol use and AUD-severity. Conclusion: European ELDERLY-participants presented typical dependence symptoms, a wide range of severity, and intense alcohol use. This may underline the clinical significance of AUD in treatment-seeking seniors.

Validating a Hazardous Drinking Index in a Sample of Sexual Minority Women: Reliability, Validity, and Predictive Accuracy

BACKGROUND

Although sexual minority women (SMW) are at increased risk of hazardous drinking (HD), efforts to validate HD measures have yet to focus on this population.

OBJECTIVES

Validation of a 13-item Hazardous Drinking Index (HDI) in a large sample of SMW.

METHODS

Data were from 700 adult SMW (age 18-82) enrolled in the Chicago Health and Life Experiences of Women study. Criterion measures included counts of depressive symptoms and post-traumatic stress disorder (PTSD) symptoms, average daily and 30-day ethanol consumption, risky sexual behavior, and Diagnostic and Statistical Manual (DSM-IV) measures of alcohol abuse/dependence. Analyses included assessment of internal consistency, construction of receiver operating characteristic (ROC) curves to predict alcohol abuse/dependence, and correlations between HDI and criterion measures. We compared the psychometric properties (diagnostic accuracy and correlates of hazardous drinking) of the HDI to the commonly used CAGE instrument.

RESULTS

KR-20 reliability for the HDI was 0.80, compared to 0.74 for the CAGE. Predictive accuracy, as measured by the area under the receiver operating characteristic curve for alcohol abuse/dependence, was HDI: 0.89; CAGE: 0.84. The HDI evidenced the best predictive efficacy and tradeoff between sensitivity and specificity. Results supported the concurrent validity of the HDI measure.

CONCLUSIONS

The Hazardous Drinking Index is a reliable and valid measure of hazardous drinking for sexual minority women.

Validity of Alcohol Use Disorder Identification Test-Korean Revised Version for Screening Alcohol Use Disorder according to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition Criteria

Background

The Alcohol Use Disorder Identification Test (AUDIT) has been widely used to identify alcohol use disorder (AUD). This study evaluated the validity of the AUDIT-Korean revised version (AUDIT-KR) for screening AUD according to Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) criteria.

Methods

This research was conducted with 443 subjects who visited the Chungnam National University Hospital for a comprehensive medical examination. All subjects completed the demographic questionnaire and AUDIT-KR without assistance. Subjects were divided into two groups according to DSM-5 criteria: an AUD group, which included patients that fit the criteria for AUD (120 males and 21 females), and a non-AUD group, which included 146 males and 156 females that did not meet AUD criteria. The appropriate cut-off values, sensitivity, specificity, and positive and negative predictive values of the AUDIT-KR were evaluated.

Results

The mean±standard deviation AUDIT-KR scores were 10.32±7.48 points in males and 3.23±4.42 points in females. The area under the receiver operating characteristic curve (95% confidence interval, CI) of the AUDIT-KR for identifying AUD was 0.884 (0.840–0.920) in males and 0.962 (0.923–0.985) in females. The optimal cut-off value of the AUDIT-KR was 10 points for males (sensitivity, 81.90%; specificity, 81.33%; positive predictive value, 77.2%; negative predictive value, 85.3%) and 5 points for females (sensitivity, 100.00%; specificity, 88.54%; positive predictive value, 52.6%; negative predictive value, 100.0%).

Conclusion

The AUDIT-KR has high reliability and validity for identifying AUD according to DSM-5 criteria.

Meta-analysis of DSM alcohol use disorder criteria severities: structural consistency is only 'skin deep'

BACKGROUND

Item response theory (IRT) analyses of alcohol use disorder (AUD) and other psychological disorders are a predominant method for assessing overall and individual criterion severity for psychiatric diagnosis. However, no investigation has established the consistency of the relative criteria severities across different samples.

METHOD

PubMed/Medline, PsycINFO, Web of Science and ProQuest databases were queried for entries relating to alcohol use and IRT. Study data were extracted using a standardized data entry sheet. Consistency of reported criteria severities across studies was analysed using generalizability theory to estimate generalized intraclass correlations (ICCs).

RESULTS

A total of 451 citations were screened and 34 papers (30 unique samples) included in the research synthesis. The AUD criteria set exhibited low consistency in the ordering of criteria using both traditional [ICC = 0.16, 95% confidence interval (CI) 0.06-0.56] and generalized (ICC = 0.18, 95% CI 0.15-0.21) approaches. These results were partially accounted for by previously studied factors such as age and type of sample (e.g. clinical v. community), but the largest source of unreliability was the diagnostic instrument employed.

CONCLUSIONS

Despite the robust finding of unidimensional structure of AUDs, inconsistency in the relative severities across studies suggests low replicability, challenging the generalizability of findings from any given study. Explicit modeling of well-studied factors like age and sample type is essential and increases the generalizability of findings. Moreover, while the development of structured diagnostic interviews is considered a landmark contribution toward improving psychiatric research, variability across instruments has not been fully appreciated and is substantial.

Commonalities and Differences Across Substance Use Disorders: Phenomenological and Epidemiological Aspects

BACKGROUND

Although psychoactive substances vary in many ways, they have important commonalties, particularly in their ability to lead to an addiction syndrome. The field lacks an updated review of the commonalities and differences in the phenomenology of alcohol, cannabis, tobacco, stimulants, opioids, hallucinogens, sedatives/tranquilizers, and inhalants and their related substance use disorders (SUDs).

METHODS

DSM-IV and DSM-5 SUD diagnostic criteria were reviewed, as was evidence from recent epidemiological and clinical research: psychometric studies (test-retest reliability, latent trait analysis); physiological indicators (tolerance, withdrawal); prevalence and age of onset. Information was incorporated from previous reviews, PubMed and Scopus literature searches, and data from large U.S. national surveys.

RESULTS

Empirical evidence in the form of test-retest reliability and unidimensionality supports use of the same DSM-IV dependence or DSM-5 SUD diagnostic criteria across substances. For most substances, the criteria sets were generally most informative in general population samples at moderate-to-severe levels of SUD. Across substances, 2 criteria (tolerance and use in hazardous situations) were identified as functioning differently in population subgroups. Since substances have different pharmacological effects, withdrawal is assessed using substance-specific symptoms, while tolerance is not; issues remain with the assessment of tolerance. Alcohol, tobacco, and cannabis were consistently identified as the substances with earliest onset of use, highest prevalence of lifetime use, and highest prevalence of lifetime disorder.

CONCLUSIONS

Despite differences between psychoactive substances, the generic DSM criteria set appears equally applicable across substances. Additional studies of tolerance and hazardous use will be useful for future nosologies. Alcohol, cannabis, and tobacco are the substances with the greatest public health impact due to the high prevalence and early onset of their use, and the potential all 3 substances have to lead to addiction.

Investigating dimensionality and measurement bias of DSM-5 alcohol use disorder in a representative sample of the largest metropolitan area in South America

BACKGROUND

Given the recent launch of a new diagnostic classification (DSM-5) for alcohol use disorders (AUD), we aimed to investigate its dimensionality and possible measurement bias in a non-U.S.

METHODS

The current analyses were restricted to 948 subjects who endorsed drinking at least one drink per week in the past year from a sample of 5037 individuals. Data came from São Paulo Megacity Project (which is part of World Mental Health Surveys) collected between 2005 and 2007. First, exploratory factor analysis (EFA) was carried out to test for the best dimensional structure for DSM-5-AUD criteria. Then, item response theory (IRT) was used to investigate the severity and discrimination properties of each criterion of DSM-5-AUD. Finally, differential criterion functioning (DCF) were investigated by socio-demographics (income, gender, age, employment status, marital status and education). All analyses were performed in Mplus software taking into account complex survey design features.

RESULTS

The best EFA model was a one-dimensional model. IRT results showed that the criteria "Time Spent" and "Given Up" have the highest discrimination and severity properties, while the criterion "Larger/Longer" had the lowest value of severity, but an average value of discrimination. Only female gender had DCF both at criterion- and factor-level, rendering measurement bias.

CONCLUSION

This study reinforces the existence of a DSM-5-AUD continuum in the largest metropolitan area of South America, including subgroups that had previously higher rates of alcohol use (lower educational/income levels). Lower DSM-5-AUD scores were found in women.

From DSM-IV to DSM-5 alcohol use disorder: an overview of epidemiological data

INTRODUCTION

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) has made several changes to criteria for alcohol use disorder (AUD). The objective of this systematic review is to assess if new DSM-5 diagnostic criteria will increase the prevalence rates of AUD in clinical and non-clinical samples as compared with DSM-IV criteria.

METHODS

We searched PubMed, Scopus, and PsycINFO (via ProQuest) electronic databases, with no language restrictions. We included studies with data available on both DSM-IV (and DSM-IV-TR) and DSM-5 AUD in samples of adults, estimating from each study an expected increase in prevalence rates with relevant 95% confidence intervals (CIs).

RESULTS

Twelve studies were included in this review. Seven studies showed an increase, two no substantial difference, and three a decrease in AUD prevalence according to DSM-5 diagnostic criteria, with differences in rates (95% CIs) varying between -12.4% (-27.4 to +5.6%) and +61.3% (+46.7 to +77.3%). Additional analyses provided confirmatory results.

CONCLUSIONS

DSM-5 diagnostic criteria seem to inflate prevalence rates of AUD as compared with DSM-IV. The increasing likelihood of a DSM-5 AUD diagnosis may be explained by the amount of DSM-IV 'diagnostic orphans' which are more prevalent than DSM-IV single-criterion alcohol abuse individuals. Further research should be aimed to study if similar trends are detectable also for other substance use disorders that experienced similar changes in DSM-5 diagnostic criteria.

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.
