Alternate Title: NCS-2, 2001-2002
Principal Investigator(s): Kessler, Ronald, Harvard University. Harvard Medical School. Department of Health Care Policy
The NCS-2 was a reinterview of people who participated in the Baseline (NCS-1), carried out a decade after the initial baseline survey. The aim was to collect information about changes in mental disorders, substance use disorders, and the predictors and consequences of these changes over the ten years between the two surveys. The collection contains three parts: the main survey, demographic data, and diagnostic data. In the main survey, respondents were asked about general physical and mental health. Questions focused on a variety of health issues, including limitations caused by respondents' health issues, substance use, childhood health, life-threatening illnesses, chronic conditions, medications taken in the past 12 months, level of functioning and symptoms experienced in the past 30 days, and any services used by the respondents since the (NCS-1). Additional questions focused on mental disorders including depression, bipolar disorder, specific and social phobias, generalized anxiety, intermittent explosive disorder, suicidality, post-traumatic stress disorder, neurasthenia, pre-menstrual dysphoric disorder, attention deficit/hyperactivity disorder, oppositional defiant disorder, conduct disorder, and separation anxiety. Respondents were also asked about their lives in general, with topics including employment, finances, marriage, children, their social lives, and stressful life events experienced in the past 12 months. Additionally, two personality assessments were included consisting of respondents' opinions on whether various true/false statements accurately described their personalities. Another focus of the main survey dealt with substance use and abuse, nonmedical use of prescription drugs, and polysubstance use. Part two contains demographic and other background information including age, education, employment, household composition, household income, marital status, and region. Part three of the collection focused on whether respondents met diagnostic criteria for psychological disorders asked about in the main survey. Interview questions in the NCS-2 Main Survey were customized to each respondent based on previous responses in the Baseline (NCS-1).
