Personnel and Training Required

The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews*. The interviewer should be trained to prompt respondents further if a "don't know" response is provided.

* There are multiple modes to administer this question (e.g., pencil and paper and computer-assisted interviews).

Equipment Needs

While the source protocol was developed to be administered by a computer-assisted instrument, the Psychiatric Working Group acknowledges these questions can be administered in a non-computerized format (i.e. pencil and paper instrument). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer/handheld computer to administer a computer-assisted questionnaire

Research Domain Information

Release Date:

May 12, 2010

Definition

A questionnaire to assess sleep disorders, a broad group of disorders that can be caused by endogenous disturbances in the sleep-wake or timing cycles (APA, 2000).

Purpose

This measure is used to screen an individual for the presence of sleep disorders. Sleep disorders are comorbid with a wide variety of health conditions. For example, sleep abnormalities are commonly reported in conjunction with most mental disorders and are also often associated either with a general medical condition or medications used to treat a condition. Additionally, some sleep disorders, such as predisposition toward light, demonstrate a familial pattern indicating a genetic and/or environmental cause (APA, 2000).

Selection Rationale

The National Institute of Mental Health (NIMH) Sleep Patterns and Problems was vetted against similar protocols and selected because it has been used in the National Institute of Mental Health Family Study and covers many areas of sleep disorders.
