Measuring Sleep Disturbance Among Cancer Patients
NCT00505544 · View on ClinicalTrials.gov ↗
Study Summary
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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00505544
The ClinicalTrials.gov registry entry for NCT00505544 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 459 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is M.D. Anderson Cancer Center, which has 2,992 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Advanced Cancer appearing as the primary indexed condition, and to 2 interventions — of which Questionnaire is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00505544 reports 2 study locations spanning 1 distinct geographic area — top geographies include Texas. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
