SRN web-education committee members identified commonly used and validated questionnaires that are relevant to research and clinical practice of both adult and pediatric Sleep Medicine. A brief description of each questionnaire is presented, as well as their original and related references. Given licensing requirements, it is recommended that the readers directly contact the specified authors for permission to use these questionnaires.
Reliability: Reliability in questionnaire studies relates to the ability of the questionnaire to produce the same results if tested multiple times.
- Test-retest correlations at two time points (≥0.7 are considered reasonable evidence of reliability (Nunnally JC. Psychometric theory. New York: McGraw-Hill1978)
- Internal consistency: Cronbach alpha is a statistic used to measure the extent to which different items measure the same construct (Cronbach 1984). A statistic ≥0.7 is considered reasonable evidence of reliability (Nunnally JC. Psychometric theory. New York: McGraw-Hill1978).
Validity: Validity refers to whether the questionnaire measures what it intends to measure. Validity is assessed by examining correlations with other measures of the same construct.
In addition, a previously developed ATS website provides information about quality of life and functional status instruments used in the assessment of patients with pulmonary disease or critical illness.
