Second, NCS-R and NLAAS data are over 10 years old, and there may have been important changes in treatment utilization in the last decade.
The NCS-R and NLAAS include large samples of racial/ethnic minorities, established diagnostic assessments for psychiatric disorders, and extensive information on health and mental health care.
Cultural relevance and equivalence in the NLAAS
instrument: Integrating etic and emic in the development of cross-cultural measures for a psychiatric epidemiology and services study of Latinos.
The NCS-R and NLAAS were designed to include parallel assessments across most demographic characteristics and all clinical measures.
born Latino group consisted of all participants born in the United States included in the NLAAS dataset (n = 924) while the foreign-born Latino group consisted of all participants born outside the U.
Diagnostic categories assessed in both NLAAS and NCS-R studies and used in this report included 5 anxiety disorders (Social Phobia, Generalized Anxiety Disorder, Post-Traumatic Stress Disorder, Panic Disorder, and Agoraphobia), 2 depressive disorders (Major Depressive Disorder and Dysthymia), 4 substance use disorders (Alcohol Abuse, Alcohol Dependence, Drug Abuse, and Drug Dependence) and 2 eating disorders (Bulimia Nervosa and Anorexia Nervosa).
In the combined NCS-R and NLAAS samples, those who reported onset of the assessed anxiety disorders before the age of 18 were categorized as having childhood onset, while those reported onset at age 18 or older were categorized as having adult onset.
Across the pooled NCS-R and NLAAS samples, a total of 1,939 individuals reported one or more anxiety disorders.
The NLAAS shares with the CPES common core sections, including the World Mental Health Survey Initiative version of the World Health Organization Composite International Diagnostic Interview (WMH-CIDI, Kessler and Ustun 2004), the Thirty-Day Functioning, the Service Use Battery, and sociodemographic variables.
Allocating part of a limited sample to the Modified Instrument to assess survey conditioning might reduce the comparability between the NLAAS and the other CPES surveys (NCS-R and NSAL).
In order to ascertain that the randomization was implemented appropriately, we compare the sociodemographic characteristics between the NLAAS subsamples receiving the two versions of the instrument, using [chi square] tests for the association between each sociodemographic variable and instrument version (traditional versus modified).
The analyses are conducted for the entire NLAAS sample and for the Latino and Asian subsamples separately.
