Official title

The Brief Sleep Disturbance Scale: Measuring Sleep Disturbance Among Cancer Patients

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Objectives: Primary Objectives: 1. To establish concurrent criterion-related validity of the Brief Sleep Disturbance Scale (BSDS) by correlating the scale with the Pittsburgh Sleep Quality Index. 2. To evaluate the construct validity of the BSDS through exploratory factor analysis. 3. To examine possible predictors of sleep disturbance. 4. To evaluate the reliability of the BSDS using Cronbach's coefficient alpha and test-retest reliability. 5. To evaluate the sensitivity of the BSDS by administering it to the same group of patients (n = 60) prior to treatment with a regimen associated with sleep disturbance, during 4 weeks of treatment, and upon completion of treatment. 6. To evaluate the psychometric properties of the BSDS in a sample of community dwelling adults. Secondary Objective: 1\. To obtain pilot data from a small sample of patients who will wear an actigraph for one week.
