In addition, the DIAMOND contains diagnostic modules for:

• Trauma- and stressor-related disorders, including:
        o Posttraumatic stress disorder
        o Acute stress disorder
        o Adjustment disorder
• Schizophrenia spectrum and other psychotic disorders, including:
        o Schizophrenia
        o Schizoaffective disorder
        o Delusional disorder
• Feeding and eating disorders, including:
        o Anorexia nervosa
        o Bulimia nervosa
        o Binge eating disorder
        o Avoidant/restrictive food intake disorder
• Somatic symptom and related disorders, including:
        o Somatic symptom disorder
        o Illness anxiety disorder
• Substance-related and addictive disorders, including:
        o Alcohol use disorder
        o Drug use disorders

The DIAMOND shows very good inter-rater reliability, test-retest reliability, and convergent and divergent validity. Through its use of “skip” rules, the DIAMOND can be administered to most patients in approximately 1 hour.

A self-report screening questionnaire can be given to patients prior to the interview to obtain preliminary information and shorten the interview time.

DIAMOND TRAINING AND RATER CERTIFICATION

We offer an online program (total time: approximately 3 hours) that demonstrates the use of the DIAMOND, trains raters to criterion, and calculates each trainee’s inter-rater reliability with the original interviewer. 

 

This video-based program includes:
     • An introduction to the use of the DIAMOND
     • A full sample diagnostic interview
     • Test videos that quiz the trainee on whether a given symptom is present or absent

Each trainee receives a report at the end of training that documents:
     • Percent agreement of symptom questions with the original interviewer
     • Kappa values of inter-rater agreement
     • Percent agreement with diagnostic severity rating scales

The online training course is well suited for:
     • Student interviewers who are learning structured interviewing
     • Experienced interviewers who want to learn how to use the DIAMOND
     • Raters in clinical trials and other research studies
