OBJECTIVE: Sleep disturbances are one of the most prevalent health complaints in the general population. Thus, the need for validated screening instruments and prevention measures is high. The aim of the current study is to evaluate a potential single-item screening instrument and therefore, contribute to an improved early detection.

METHODS: Data from Saxony Longitudinal Study (SLS) is being analyzed. Based on data of 32nd wave (n=321, 172 women, 149 men, M age=48.42, SD=0.64), the G-Score Item #3 ("Have you had the following complaints in the last 12 months? Please indicate how often they occurred. - sleeplessness"), a potential screening instrument, is psychometrically evaluated. A Receiver Operating Characteristic (ROC)-Analysis is calculated to assess the predictive validity of the G-Score Item #3.

RESULTS: Retestreliability for the G-Score Item #3 is 0.70 (p<0.001). Correlation with the Jenkins Sleep Scale (JSS) was r=0.79 (p<0.01). The area under the curve (AUC) is 0.92, providing evidence for a very good predictive validity.

DISCUSSION AND CONCLUSION: This study provides evidence for the use of the G-Score Item #3 as a screening instrument for sleep disturbances by showing good psychometric properties and brevity.
