  • Associations between anxiety disorders, suicide ideation, and age in nationally representative samples of Canadian and American adults JOURNAL OF ANXIETY DISORDERS Raposo, S., El-Gabalawy, R., Erickson, J., Mackenzie, C. S., Sareen, J. 2014; 28 (8): 823-829


    Suicidal behaviors are of significant concern for the individuals displaying such behavior and for service providers who encounter them. Using nationally representative samples of Canadian and American adults, we aimed to examine: whether age moderates the relationship between having any anxiety disorder and suicide ideation (SI), the prevalence of SI among younger and older adults, and whether age and individual anxiety disorders were differentially associated with SI. Age moderated the relationship between any anxiety disorder and SI among Americans only. Past-year SI was less prevalent among older, compared to younger, adults; though, nearly every anxiety disorder was associated with increased odds of SI among younger and older Canadian and American adults after controlling for covariates. Effect sizes were particularly large for older American adults, but were coupled with large confidence intervals. Findings contribute to a growing literature suggesting that SI in the context of anxiety is a highly prevalent and complex mental health problem across the adult lifespan.

  • Time Does Not Heal All Wounds: Older Adults Who Experienced Childhood Adversities Have Higher Odds of Mood, Anxiety, and Personality Disorders AMERICAN JOURNAL OF GERIATRIC PSYCHIATRY Raposo, S. M., Mackenzie, C. S., Henriksen, C. A., Afifi, T. O. 2014; 22 (11): 1241-1250


    We aimed to examine the prevalence of several types of childhood adversity across adult cohorts, whether age moderates the effect of childhood adversity on mental health, the relationship between childhood adversity and psychopathology among older adults, the dose-response relationship between number of types of childhood adversities and mental disorders in later life, and whether lifetime mental health treatment reduces the odds of psychopathology among older survivors of childhood adversity.In a population-based, cross-sectional study on a nationally representative U.S. sample, we studied 34,653 community-dwelling Americans 20 years and older, including 7,080 adults 65 years and older from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions. Trained lay interviewers assessed past-year mood and anxiety disorders and lifetime personality disorders. Participants self-reported childhood adversity based on questions from the Adverse Childhood Experiences Study.Childhood adversity was prevalent across five age cohorts. In our adjusted models, age did not moderate the effect of childhood adversity on mental disorders. Older adults who experienced childhood adversity had higher odds of having mood (odds ratio: 1.73; 95% confidence interval: 1.32-2.28), anxiety (odds ratio: 1.48; 95% confidence interval: 1.20-1.83), and personality disorders (odds ratio: 2.11; 95% confidence interval: 1.75-2.54) after adjusting for covariates. An increasing number of types of childhood adversities was associated with higher odds of personality disorders and somewhat higher odds of anxiety disorders. Treatment-seeking was associated with a reduced likelihood of anxiety and, especially, mood disorders in older adult childhood adversity survivors.These results emphasize the importance of preventing childhood adversity and intervening once it occurs to avoid the negative mental health effects that can last into old age.

  • Age, Period, and Cohort Effects in Psychological Distress in the United States and Canada AMERICAN JOURNAL OF EPIDEMIOLOGY Keyes, K. M., Nicholson, R., Kinley, J., Raposo, S., Stein, M. B., Goldner, E. M., Sareen, J. 2014; 179 (10): 1216-1227


    Although treatment utilization for depression and anxiety symptoms has increased substantially in the United States and elsewhere, it remains unclear whether the underlying population distribution of psychological distress is changing over time. We estimated age, period, and cohort effects using data from 2 countries over more than 20 years, including National Health Interview Surveys from 1997 to 2010 (n = 447,058) and Canadian Community Health Surveys from 2000 to 2007 (n = 125,306). Psychological distress was measured with the Kessler Psychological Distress Scale. By period, both countries showed the highest levels of psychological distress in 2001 and the lowest levels in 2007. By age, psychological distress was highest in adolescence and during the late 40s and early 50s. By cohort, Canadian Community Health Survey results indicated a decreasing cohort effect among those born in 1922-1925 through 1935-1939 (β = -0.36, 95% confidence interval: -0.45, -0.27) and then a continuously increasing cohort effect during the remainder of the 20th century through 1989-1992 (β = 0.49, 95% confidence interval: 0.38, 0.61). The National Health Interview Survey data captured earlier-born cohorts and indicated an increased cohort effect for the earliest born (for 1912-1914, β = 0.44, 95% confidence interval: 0.26, 0.61). In sum, individuals in the oldest and more recently born birth cohorts have higher mean psychological distress symptoms compared with those born in midcentury, underscoring the importance of a broad, population-level lens for conceptualizing mental health.
