To present nationally representative data on 12-month and lifetime prevalence, correlates, and comorbidity of DSM-IV major depressive disorder (MDD) among adults in the United States. Design/Setting/Participants: Face-to-face survey of more than 43 000 adults aged 18 years and older residing in households and group quarters in the United States. Main Outcome Measures: Prevalence and associations of MDD with sociodemographic correlates and Axis I and II disorders. Results: The prevalence of 12-month and lifetime DSM-IV MDD was 5.28% (95% confidence interval, 4.98-5.57) and 13.23% (95% confidence interval, 12.64-13.81), respectively. Being female; Native American; middleaged; widowed, separated, or divorced; and low income increased risk, and being Asian, Hispanic, or black decreased risk (PϽ.05). Women were significantly more

A high proportion of New York City public school children had a probable mental disorder 6 months after September 11, 2001. The data suggest that there is a relationship between level of exposure to trauma and likelihood of child anxiety/depressive disorders in the community. The results support the need to apply wide-area epidemiological approaches to mental health assessment after any large-scale disaster.

Investigations of the relationship between pain conditions and psychopathology have largely focused on depression and have been limited by the use of non-representative samples (e.g. clinical samples). The present study utilized data from the Midlife Development in the United States Survey (MIDUS) to investigate associations between three pain conditions and three common psychiatric disorders in a large sample (N = 3,032) representative of adults aged 25-74 in the United States population. MIDUS participants provided reports regarding medical conditions experienced over the past year including arthritis, migraine, and back pain. Participants also completed several diagnostic-specific measures from the Composite International Diagnostic Interview-Short Form [Int. J. Methods Psychiatr. Res. 7 (1998) 171], which was based on the revised third edition of the Diagnostic and Statistical Manual of Mental Disorders [American Psychiatric Association 1987]. The diagnoses included were depression, panic attacks, and generalized anxiety disorder. Logistic regression analyses revealed significant positive associations between each pain condition and the psychiatric disorders (Odds Ratios ranged from 1.48 to 3.86). The majority of these associations remained statistically significant after adjusting for demographic variables, the other pain conditions, and other medical conditions. Given the emphasis on depression in the pain literature, it was noteworthy that the associations between the pain conditions and the anxiety disorders were generally larger than those between the pain conditions and depression. These findings add to a growing body of evidence indicating that anxiety disorders warrant further attention in relation to pain. The clinical and research implications of these findings are discussed.

The authors' objective was to determine the association between the 'big-five' personality traits and mental and physical disorders among adults in the United States. The Midlife Development in the United States Survey, a nationally representative sample of 3032 adults ages 25-74, was used to determine the association between the five-factor traits of personality and common mental and physical disorders. Findings are consistent with and extend previous results showing that conscientiousness is associated with significantly reduced likelihood of a wide range of mental and physical disorders among adults in the general population, and inversely that neuroticism is associated with increased rates. Among adults with physical illnesses, associations were found between personality and likelihood of physical limitations, especially conscientiousness. These findings provide a framework upon which research on complex causal processes may proceed. Thus future research attention might profitably be directed to conscientiousness-relevant processes, such as adherence to health and treatment recommendations and internalization of healthy societal norms for sensible health-related behavior.

The prevalence of depression increased significantly in the USA from 2005 to 2015. The rate of increase in depression among youth was significantly more rapid relative to older groups. Further research into understanding the macro level, micro level, and individual factors that are contributing to the increase in depression, including factors specific to demographic subgroups, would help to direct public health prevention and intervention efforts.

Consistent with previous work, these results suggest that self-reported childhood trauma is associated with increased risk of a range of physical illnesses during adulthood. Future research that includes replication of these findings using prospectively assessed physical and mental disorders with objectively measured biological data using a longitudinal design, including other known risk factors for these diseases and more detailed information on specific forms of abuse, is needed to understand the potential mechanisms of these links.
