Substance abuse in older adults: Review and recommendations for education and practice in medical settings

Age as a moderator of motivational interviewing and nondirective client-centered psychotherapy for alcohol use disorder: An exploratory study

BACKGROUND

Motivational interviewing (MI) is a widely used intervention applied to a host of health behaviors, including alcohol consumption among individuals with alcohol use disorder (AUD). Age is an underexplored moderator of MI for treating AUD, with the impact of comparing older individuals with their younger counterparts virtually unexplored. Also unexplored is whether age is associated with distinct mechanisms of change (e.g., motivation and self-efficacy) within treatment.

METHODS

This secondary data analysis utilizes combined data from two previous studies (total N = 228) that both aimed to test MI's mechanisms of action in the context of a goal for moderated drinking. Both studies had three conditions: MI, nondirective listening (NDL), and a self-change condition (SC). In the current analyses, the moderating impact of continuous age and age group, <51 (younger adults, YA) versus ≥51 (older adults, OA), on the impact of MI on alcohol use compared to NDL and SC were tested using generalized linear models. Age differences in confidence and commitment to reduce heavy drinking during treatment were also explored.

RESULTS

Age group by condition differences emerged, where NDL significantly reduced drinking among YA but not OA (mean -12 vs. -3 standard drinks, respectively). Among OA, MI outperformed NDL but not SC, though the effect was weak. Confidence and commitment during treatment were not significantly different across age-by-condition groups.

CONCLUSION

Findings underscore the importance of understanding the impact of age on treatment effectiveness, as providing a nondirective intervention for OA with AUD could provide suboptimal treatment. Further research is needed to explore these differential effects.

U.S. older adults' heroin and psychostimulant use treatment admissions, 2012-2019: Sociodemographic and clinical characteristics

BACKGROUND

Increases in U.S. older adults' nonprescription opioid and psychostimulant use call for examining their treatment admissions for these substances.

METHODS

Using admissions age 55 + involving heroin (N = 299,073) from the 2012-2019 Treatment Episode Data Set-Admissions, we examined trends and sociodemographic and clinical characteristics of three groups: (1) heroin-only admissions (i.e., not involving cocaine or methamphetamine), (2) heroin-cocaine admissions, and (3) heroin-methamphetamine admissions. Bivariable and multivariable logistic regression analyses were conducted to examine the research questions.

RESULTS

Between 2012 and 2019, the numbers of both heroin-only and heroin-cocaine admissions increased 2.3-fold and heroin-methamphetamine admissions increased seven-fold. First time heroin-methamphetamine admissions increased 18-fold. Heroin-methamphetamine admissions were concentrated in the Western region and heroin-cocaine admissions in the Northeastern region. Multivariable analyses showed a nearly 6 times higher relative risk ratio (RRR; 95% CI=5.24-6.74) for heroin-methamphetamine vs. heroin-only admissions in 2019 compared to 2012. Being non-Hispanic Black, compared to non-Hispanic White, was associated with a RRR of 2.4 (95% CI=2.34-2.46) for heroin-cocaine admissions and a RRR of 0.14 (95% CI=0.12-0.15) for heroin-methamphetamine admissions. Late-onset heroin use, experience of homelessness and other psychiatric problems, and past 30-day arrest episodes were associated with a higher likelihood of heroin-cocaine and heroin-methamphetamine admissions, while injection drug use (IDU) was associated with a higher likelihood of heroin-methamphetamine admissions only.

CONCLUSIONS

Healthcare providers should assess and monitor psychostimulant, methamphetamine in particular, use among older adults. Those who use heroin and psychostimulants should receive substance use treatment and help to secure stable housing and meet other living needs.

Forensic Aspects of Substance Use in Older Adults

Older adults are at high risk of developing more severe consequences of substance use. Due to aging, they may also have multiple medical and psychiatric comorbidities as well as cognitive impairment. This may lead to forensic issues both in terms of civil and criminal matters. This article will review the forensic issues of substance use and their relevance to the older population in particular.

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.

Alcohol consumption patterns of older adults: a study in a regional town in Western Australia

AIM

This study aimed to demonstrate that opportunistic health screening at health expos can provide an overall impression of alcohol consumption patterns.

DESIGN

A repeated cross-sectional survey design, completed over a four-year period (2011-2014), was used to assess the risk of harmful alcohol consumption, within a community setting of older adults, in the South West region of Western Australia.

METHODS

An alcohol screening survey (AUDIT) was used to collect data on alcohol consumption patterns on those aged 65 years and over. A total of 411 surveys were completed.

RESULTS

There was a statistically significant difference in mean risk scores across the four years (p < .001). 6.3-22.2% of survey completers presented as 'risky', and a further 3.8-12.3% as 'high risk' in terms of alcohol consumption.

CONCLUSIONS

Opportunistic screening for alcohol consumption during health expos can aid the identification of at-risk individuals who may require further education or treatment.

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.

Report of Recommendations: The Annapolis Coalition Conference on Behavioral Health Work Force Competencies

In May 2004, the Annapolis Coalition on Behavioral Health Workforce Education convened a national meeting on the identification and assessment of competencies. The Conference on Behavioral Health Workforce Competencies brought leading consumer and family advocates together with other experts on competencies from diverse disciplines and specialties in the fields of both mental health care and substance use disorders treatment. Aided by experts on competency development in business and medicine, conference participants have generated 10 consensus recommendations to guide the future development of workforce competencies in behavioral health. This article outlines those recommendations. A collaborative effort to identify a set of core or common competencies is envisioned as a key strategy for advancing behavioral health education, training, and other workforce development initiatives.
