SDIA Summary & Development

The Sleep Disorders Inventory for Adults (SDIA) has been provided on this website due to requests from many professionals stating there is a need for a comprehensive sleep screening inventory for adults similar to the Sleep Disorders Inventory for Students-Adolescent (SDIS-A) screening form. Therefore, while we were producing this digital Internet website for the newly revised SDIS-Revised-Children’s and Adolescent screenings, we have also developed the Adult version:

The Sleep Disorders Inventory for Adults (SDIA) is not a new concept or creation. We have taken the popular SDIS-Revised-Adolescent version with its additional Medical History questions, and merely changed the wording from “your adolescent” or “your son or daughter” to address the adult instead with “you, your, …).

The rationale for this is that the sleep behaviors and problems of an older adolescent are similar to an adult, and since the validity and reliability of the SDIS-Adolescent and the SDIS-R-A screening versions is high, we believe it will also be high for SDIA -Adults version (please view the “SDIS-R Summary/Development” document under “Product Information” to see the favorable validity and reliability coefficient scores). We believe the validity and reliability scores for the SDIA will be good-to-high because it often becomes easier to identify a sleep disorder as the person gets older and the sleep problem/disorder usually becomes more severe with time. The only changes we have made to the SDIA right now is to make the cut-off scores for each sleep scale two points higher because it is logical to expect adult scores to be slightly higher or more severe than adolescents. Although the SDIA does not screen for every sleep disorder in adults, it screens for many of the most harmful and frequently occurring sleep disorders in adults. However, please note that this inventory is NOT SUITED for assessment of Shift Workers, so the questions for the Delayed Sleep Phase Syndrome (DSPS) scale will confuse a shift worker and the results of the DSPS scale will be Inaccurate. Please do not give the SDI-A to Shift Workers unless the professional would like to have information on SRBDs or PLMD.

At the present time, the SDIA should only be used to get some fairly good hypotheses of the adult’s sleep problems because the SDIA has not yet undergone validation studies. We will be doing this over the 2019-2020 time period. If you are a professional working with a sleep clinic/hospital and would be interested in participating in such a validation study with your patients/clients, please contact Dr. Marsha Luginbuehl at (307) 248-0226 or childuplift@aol.com.
