DSM-5 field trials in the United States and Canada, Part I: study design, sampling strategy, implementation, and analytic approaches.

Objective: This article discusses the design,sampling strategy, implementation,and data analytic processes of the DSM-5 Field Trials.

Method: The DSM-5 Field Trials were conducted by using a test-retest reliability design with a stratified sampling approach across six adult and four pediatric sites in the United States and one adult site in Canada. A stratified random sampling approach was used to enhance precision in the estimation of the reliability coefficients.

DSM-5 field trials in the United States and Canada, Part III: development and reliability testing of a cross-cutting symptom assessment for DSM-5.

Objective: The authors sought to document, in adult and pediatric patient populations, the development, descriptive statistics,and test-retest reliability of cross-cutting symptom measures proposed for inclusion in DSM-5.

Method: Data were collected as part of the multisite DSM-5 Field Trials in large academic settings. There were seven sites focusing on adult patients and four sites focusing on child and adolescent patients.

DSM-5 field trials in the United States and Canada, Part II: test-retest reliability of selected categorical diagnoses.

Objective: The DSM-5 Field Trials were designed to obtain precise (standard error,0.1) estimates of the intraclass kappa asa measure of the degree to which two clinicians could independently agree on the presence or absence of selected DSM-5 diagnoses when the same patient was interviewed on separate occasions, in clinical settings, and evaluated with usual clinical interview methods.

Method: Eleven academic centers in the United States and Canada were selected,and each was assigned several target diagnoses frequently treated in that setting.

Relation of anxiety and adherence to risk-reducing recommendations following myocardial infarction.

Unlike depression, the relation between anxiety and the adherence to risk-reducing recommendations after myocardial infarction (MI) has not been well studied. The aim of this study was to explore the effect of anxiety on adherence after MI. Patients (n = 278) hospitalized for MI were assessed for anxiety using the Beck Anxiety Inventory during the hospitalization (baseline) and at 4 months of follow-up.
