Anxiety Disorders Interview Schedule for DSM-IV PDF Free Download

If you are looking for a comprehensive and reliable diagnostic tool for anxiety disorders, you might be interested in the Anxiety Disorders Interview Schedule for DSM-IV (ADIS-IV). This instrument is designed to assess the presence and severity of anxiety disorders according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). In this article, we will explain what ADIS-IV is, why you should use it, how to administer it, and what are its features, benefits, and limitations. We will also tell you how to get ADIS-IV PDF for free, if possible.

What is ADIS-IV?

ADIS-IV is a semi-structured interview that covers the following anxiety disorders: panic disorder, agoraphobia, social phobia, specific phobia, obsessive-compulsive disorder, posttraumatic stress disorder, generalized anxiety disorder, acute stress disorder, anxiety disorder due to a general medical condition, substance-induced anxiety disorder, and anxiety disorder not otherwise specified. It also includes sections on mood disorders (major depressive disorder, dysthymic disorder, bipolar disorder), somatoform disorders (somatization disorder, conversion disorder, pain disorder, hypochondriasis), and psychotic disorders (schizophrenia, schizoaffective disorder, delusional disorder). Additionally, it assesses the presence of other clinical features that may be relevant for diagnosis and treatment planning, such as suicidal ideation and behavior, substance use and abuse, medical history and current medications, family history of psychiatric disorders, psychosocial stressors and resources, and impairment and disability.

Why use ADIS-IV?

ADIS-IV is one of the most widely used diagnostic instruments for anxiety disorders in clinical and research settings. It has several advantages over other methods of assessment, such as self-report questionnaires or unstructured interviews. Some of these advantages are:

  • It provides a comprehensive evaluation of anxiety disorders and related conditions in a single interview.

  • It follows a standardized format that ensures consistency and comparability across interviewers and settings.

  • It allows for a detailed exploration of the symptoms, onset, course, frequency, duration, severity, distress, interference, avoidance, anticipatory anxiety, safety behaviors, triggers, and coping strategies of each disorder.

  • It incorporates diagnostic rules and decision trees that facilitate the differential diagnosis and rule out of comorbid or alternative conditions.

  • It generates a numerical score for each disorder that reflects its clinical significance and can be used to monitor changes over time or across treatments.

How to administer ADIS-IV?

ADIS-IV can be administered by trained clinicians or lay interviewers who have received adequate instruction and supervision. The interview can be conducted face-to-face or over the phone. The interview typically takes between 90 and 120 minutes to complete. However, this may vary depending on the number and complexity of the disorders assessed. The interview consists of four main parts:

  • The introductory section, which collects demographic and background information, such as age, gender, education, occupation, marital status, living situation, ethnicity, and language.

  • The diagnostic modules, which cover the anxiety disorders and related conditions in a hierarchical order, starting with the most severe or impairing disorder. Each module begins with a screening question that determines whether the disorder is present or absent. If the disorder is present, the interviewer proceeds to ask a series of questions that elicit the diagnostic criteria and other relevant information. If the disorder is absent, the interviewer skips to the next module.

  • The whole life section, which asks about the lifetime occurrence and impairment of each disorder assessed in the diagnostic modules. This section also includes questions about the age of onset, duration, and treatment history of each disorder.

  • The summary and feedback section, which provides a summary of the interview results, including the diagnoses, scores, and recommendations for further evaluation or treatment. The interviewer also gives feedback to the client about his or her condition and answers any questions or concerns.

Features of ADIS-IV

Structure and content

ADIS-IV is composed of two versions: a long version and a short version. The long version includes all the diagnostic modules and sections described above. The short version includes only the diagnostic modules for the anxiety disorders and mood disorders. The short version can be used when the focus of the assessment is on these disorders and when there is no suspicion or evidence of other psychiatric conditions. The short version can also be used as a follow-up measure to evaluate changes in symptoms or diagnosis over time or across treatments.

ADIS-IV is accompanied by a clinician manual that provides detailed instructions on how to administer, score, and interpret the interview. The manual also includes examples of typical and atypical responses, probes and clarifications, diagnostic rules and decision trees, scoring guidelines and cut-offs, and case vignettes. The manual is available in both English and Spanish languages.

Scoring and interpretation

ADIS-IV generates two types of scores for each disorder: a diagnosis score and a severity score. The diagnosis score indicates whether the disorder is present or absent according to the DSM-IV criteria. The diagnosis score can be either 0 (absent) or 1 (present). The severity score reflects the degree of clinical significance of the disorder based on its frequency, duration, distress, interference, avoidance, and impairment. The severity score can range from 0 (no symptoms) to 8 (very severe symptoms). A severity score of 4 or higher indicates that the disorder is clinically significant and requires treatment.

The interpretation of ADIS-IV scores depends on the purpose and context of the assessment. For example, in clinical settings, ADIS-IV scores can be used to inform diagnosis, treatment planning, case formulation, progress monitoring, and outcome evaluation. In research settings, ADIS-IV scores can be used to screen participants for inclusion or exclusion criteria, to measure baseline characteristics or change variables, to test hypotheses or answer research questions, or to compare groups or conditions.

Reliability and validity

ADIS-IV has been extensively evaluated for its psychometric properties in various samples and settings. The results of these studies have shown that ADIS-IV has high levels of reliability and validity for assessing anxiety disorders and related conditions. Some of these studies are summarized below:

  • Brown et al. (2001) examined the interrater reliability and concurrent validity of ADIS-IV in a sample of 226 adults with anxiety disorders who participated in a randomized controlled trial of cognitive-behavioral therapy. They found that ADIS-IV had excellent interrater reliability for both diagnosis (kappa = 0.85) and severity (intraclass correlation coefficient = 0.93) scores. They also found that ADIS-IV had good concurrent validity with self-report measures of anxiety symptoms (correlations ranging from 0.50 to 0.80).

  • Fresco et al. (2006) investigated the test-retest reliability and discriminant validity of ADIS-IV in a sample of 65 adults with generalized anxiety disorder who participated in a treatment outcome study. They found that ADIS-IV had good test-retest reliability for both diagnosis (kappa = 0.75) and severity (intraclass correlation coefficient = 0.79) scores over a 2-week interval. They also found that ADIS-IV had good discriminant validity with self-report measures of depression symptoms (correlations ranging from -0.10 to -0.30).

Di Nardo et al. (1994) evaluated the convergent validity and discriminant validity of ADIS-IV in a sample of 180 adults 71b2f0854b
