Development of a Comprehensive ADL Scale for Stroke Patients

Status Recruiting

Clinical Trial Summary

our research team will develop a new CADL scale for stroke patients over the next three years.

In the first year, we had established a CADL item bank of 50 items. The investigators will administer the 50 items on 300 patients with stroke living in the community. Then we will select 10 to 15 items from the item bank for the CADL scale based on the International Classification of Functioning, Disability and Health (ICF), the opinions of an expert panel, and Rasch analysis. It is anticipated that the CADL scale will have unidimensionality, an interval level of measurement, soundly psychometric characteristics, a reduced number of items, and ease of administration.

In the second and third years, we will compare the psychometric properties of the CADL scale and the combined BI and FAI scale. The psychometric properties investigated will include reliability (e.g. inter-rater reliability, intra-rater reliability, and internal consistency), validity (e.g. concurrent validity, convergent validity, predictive validity and discriminant validity), and responsiveness. A total of 150 patients will be recruited. Both the CADL scale and the combined BI and FAI scale will be used on patients from the initial stage (within one month) to six months after hospital discharge. The results will be useful for researchers and clinicians to determine whether the CADL scale is better than the combined BI and FAI scale in stroke patients.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
