Prevalence of mood, anxiety, and substance-abuse disorders for older Americans in the national comorbidity survey-replication.

OBJECTIVES Current information on the prevalence of psychiatric disorders among older adults in the United States is lacking. Prevalence of anxiety, mood, and substance disorders was examined by age (18-44, 45-64, 65-74, and 75 years and older) and sex. Covariates of disorders for older adults (65 years and older) were explored. DESIGN Cross-sectional epidemiologic study, using data from the National Comorbidity Survey-Replication. SETTING Community-based epidemiologic survey. PARTICIPANTS Representative national sample of community-dwelling adults in the United States. MEASUREMENTS The World Health Organization Composite International Diagnostic Interview was used to assess Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition psychiatric disorders. RESULTS Prevalence of 12-month and lifetime mood, anxiety, and substance-use disorders was lower for older adults (65 years and older) than younger age groups: 2.6% for mood disorder, 7.0% for anxiety disorder, 0 for any substance-use disorder, and 8.5% for any of these disorders (for any disorder, 18-44 years = 27.6%, 45-64 years = 22.4%). Among older adults, presence of a 12-month anxiety disorder was associated with female sex, lower education, being unmarried, and three or more chronic conditions. Presence of a 12-month mood disorder was associated with disability. Similar patterns were noted for lifetime disorders (any disorder: 18-44 years = 46.4%, 45-64 years = 43.7%, and 65 years and older = 20.9%). CONCLUSIONS This study documents the continued pattern of lower rates of formal diagnoses for elders. These rates likely underestimate the burden of late-life psychiatric disorders, given the potential for underdiagnosis, clinical significance of subthreshold symptoms, and lack of representation from high-risk older adults (e.g., medically ill, long-term care residents).

Comorbidity of Depressive and Anxiety Disorders for Older Americans in the National Comorbidity Survey-Replication

OBJECTIVE To identify age differences in the 12-month and lifetime comorbidity of depressive and anxiety disorders for adults (18-64 years) compared with older adults (65 years and older) in a nationally representative sample of community-dwelling adults in the United States. DESIGN Cross-sectional epidemiologic study, using data from the National Comorbidity Survey-Replication public use dataset. SETTING Community-based epidemiologic survey. PARTICIPANTS Representative national sample of community-dwelling adults in the United States. MEASUREMENTS The World Health Organization Composite International Diagnostic Interview was used to assess Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition psychiatric disorders. RESULTS More than half of respondents with a 12-month major depressive disorder (MDD) had a comorbid anxiety disorder or dysthymia (18-64 years = 60.6%; 65 years and older = 51.8%). High rates of MDD were also found for those with anxiety disorders across both age groups, highest in the 18-64 years group for generalized anxiety disorder (28.5%) and highest in the 65 years and older group for panic disorder (36.7%). Age group did not predict 12-month diagnosis of a comorbid anxiety disorder among those with a depressive disorder in multivariate logistic regression. Onset of anxiety disorders preceded onset of depressive disorders for most older adults (77.6%). CONCLUSIONS Depressive and anxiety disorders frequently cooccurred in this representative sample of community-dwelling adults. Older adults experienced comorbidity to a similar extent as younger adults, suggesting high rates of comorbidity across the lifespan.

Treatment of depression in low-income older adults.

The purpose of this study was to compare cognitive-behavioral group therapy (CBGT), clinical case management (CCM), and their combination (CBGT + CCM) to treat depression in low-income older adults (60+). Sixty-seven participants with major depressive disorder or dysthymia were randomly assigned and entered into 1 of the 3 treatment conditions for 6 months. They were followed for 18 months after treatment initiation on depression and functional outcomes. CCM and CBGT + CCM led to greater improvements in depressive symptoms than CBGT, but CBGT led to greater improvements in physical functioning. All 3 conditions resulted in similar reduction of needs. Findings suggest that disadvantaged older adults with depression benefit from increased access to social services either alone or combined with psychotherapy.

The relationships between major lifetime discrimination, everyday discrimination, and mental health in three racial and ethnic groups of older adults

Objectives: To evaluate the relationships between perceived exposure to major lifetime discrimination, everyday discrimination, and mental health in three racial/ethnic groups of older adults. Design: The Health and Retirement Study is a nationally representative sample of individuals 50 years and older living in the United States. A total of 6455 Whites, 716 Latinos, and 1214 Blacks were eligible to complete a self-report psychosocial questionnaire in the year 2006. Results: Whereas 30% of the general population reported at least one type of major lifetime discrimination, almost 45% of Black older adults reported such discrimination. Relative to the other two racial/ethnic groups (82% Whites, 82.6% Blacks), Latinos were significantly less likely to report any everyday discrimination (64.2%), whereas Blacks reported the greatest frequency of everyday discrimination. Whites reported the highest levels of life satisfaction and the lowest levels of depressive symptoms. Relative to major lifetime discrimination, everyday discrimination had a somewhat stronger correlation with mental health indicators. The relationships between discrimination and mental health outcomes were stronger for White compared to Black older adults, although everyday discrimination was still significantly associated with outcomes for Black older adults. Conclusions: Black older adults experience the greatest number of discriminative events, but weaker associated mental health outcomes. This could be because they have become accustomed to these experiences, benefit from social or cultural resources that serve as buffers, or selective survival, with the present sample capturing only the most resilient older adults who have learned to cope with the deleterious effects of discrimination.

Improving recognition of late life anxiety disorders in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition: observations and recommendations of the Advisory Committee to the Lifespan Disorders Work Group

Recognition of the significance of anxiety disorders in older adults is growing. The revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM) provides a timely opportunity to consider potential improvements to diagnostic criteria for psychiatric disorders for use with older people. The authors of this paper comprise the Advisory Committee to the DSM5 Lifespan Disorders Work Group, the purpose of which was to generate informative responses from individuals with clinical and research expertise in the field of late‐life anxiety disorders.

Hopeful thinking, participation, and depressive symptoms three months after stroke

This study was designed to examine hopeful thinking, depressive symptoms, and participation in meaningful activities and roles for survivors 3 months after stroke. It was predicted that: (a) participation would predict lower depressive symptoms; (b) higher hopeful thinking (i.e., beliefs in ones goal pursuit abilities) would predict lower depressive symptoms; and (c) higher hopeful thinking would predict better participation. Three months after stroke, 110 participants completed measures of disability, participation, depressive symptoms, and hopeful thinking. Contrary to the first hypothesis, participation did not independently predict depressive symptoms after controlling for more basic activity limitations (physical, memory, communication). As predicted, hopeful thinking was the strongest predictor of depressive symptoms. Hopeful thinking did not directly predict participation, but it moderated relationships of activity functioning to participation. Results suggest that participation and hopeful thinking may contribute to the understanding of post-stroke depressive symptoms, although additional research is needed to further elucidate such contributions.

Evaluation of the factor structure and psychometric properties of the Brief Symptom Inventory-18 with homebound older adults.

Homebound older adults are at high risk for depression and anxiety. Systematic screening may increase identification of these difficulties and facilitate service usage. The purpose of this study was to investigate the factor structure, internal consistency, and concurrent validity of the Brief Symptom Inventory—18 (BSI‐18) for use as a screening instrument for depression and anxiety with homebound older adults and to examine if the BSI‐18 could be shortened further and exhibit comparable psychometric properties.

Insomnia and Health Services Utilization in Middle-Aged and Older Adults: Results From the Health and Retirement Study

BACKGROUND Complaints of poor sleep are common among older adults. We investigated the prospective association between insomnia symptoms and hospitalization, use of home health care services, use of nursing homes, and use of any of these services in a population-based study of middle-aged and older adults. METHODS We studied 14,355 adults aged 55 and older enrolled in the 2006 and 2008 waves of the Health and Retirement Study. Logistic regression was used to study the association between insomnia symptoms (0, 1, or ≥ 2) in 2006 and reports of health service utilization in 2008, after adjustment for demographic and clinical characteristics. RESULTS Compared with respondents reporting no insomnia symptoms, those reporting one symptom had a greater odds of hospitalization (adjusted odds ratio [AOR] = 1.28, 95% confidence interval [CI] = 1.15-1.43, p < .001), use of home health care services (AOR = 1.29, 95% CI = 1.09-1.52, p = .004), and any health service use (AOR = 1.28, 95% CI = 1.15-1.41, p < .001). Those reporting greater than or equal to two insomnia symptoms had a greater odds of hospitalization (AOR = 1.71, 95% CI = 1.50-1.96, p < .001), use of home health care services (AOR = 1.64, 95% CI = 1.32-2.04, p < .001), nursing home use (AOR = 1.45, 95% CI = 1.10-1.90, p = .009), and any health service use (AOR = 1.72, 95% CI = 1.51-1.95, p < .001) after controlling for demographics. These associations weakened, and in some cases were no longer statistically significant, after adjustment for clinical covariates. CONCLUSIONS In this study, insomnia symptoms experienced by middle-aged and older adults were associated with greater future use of costly health services. Our findings raise the question of whether treating or preventing insomnia in older adults may reduce use of and spending on health services among this population.

Anxiety Disorders in Older Adults: Looking to DSM5 and Beyond…

Anxiety in late life was for many years the ‘Cinderella’ of psychiatric disorders, often overshadowed by the focus on depression and dementia, and receiving little attention in research and clinical domains. As highlighted by an editorial published in this journal several years ago [1], the scientific study of anxiety in older age has a relatively brief history. Recently, however, there has been increased recognition of the prevalence and clinical consequences of anxiety disorders in older adults and lively debate about their nature and most appropriate diagnostic criteria [2, 3, 4]. The current evidence reveals that anxiety in older adults is more common than depression in community samples [5], often preceding depressive disorders [6]; moreover, co-morbid anxiety and depression has a poorer outcome than either condition alone [7]. Anxiety disorders are even more prevalent in clinical settings [8], and can have serious consequences for recovery from illness [9] and quality of life [10], as well as substantially increasing disability levels [11]. Therefore, anxiety disorders in older adults should be regarded as conditions of great public health importance.

Screening, Brief Intervention, and Referral to Treatment for Older Adults With Substance Misuse

Objectives. We compared substance use and SBIRT (Screening, Brief Intervention, and Referral to Treatment) services received for older adults screened by the Florida BRITE (BRief Intervention and Treatment of Elders) Project, across 4 categories of service providers. Methods. Staff from 29 agencies screened for substance use risk in 75 sites across 18 Florida counties. Clients at no or low risk received feedback about screening; moderate risk led to brief intervention, moderate or high risk led to brief treatment, and highest severity led to referral to treatment. Six-month follow-ups were conducted with a random sample of clients. Results. Over 5 years (September 15, 2006-September 14, 2011), 85 001 client screenings were recorded. Of these, 8165 clients were at moderate or high risk. Most received brief intervention for alcohol or medication misuse. Differences were observed across 4 categories of agencies. Health educators screening solely within medical sites recorded fewer positive screens than those from mental health, substance abuse, or aging services that screened in a variety of community-based and health care sites. Six-month follow-ups revealed a significant decrease in substance use. Conclusions. The Florida BRITE Project demonstrated that SBIRT can be extended to nonmedical services that serve older adults.
