VAlidity and Reliability of the Telephone Interview Form for Stroke Outcome Evaluation

Study Overview
=================
Brief Summary
-----------------
The investigators combined the mRS questionnaire and BI questionnaire and then developed a telephone interview form as a simple questionnaire with internal rules. The main purpose of this study is to evaluate the validity and reliability of the telephone interview form when compared with face-to-face assessment in clinically stable patients with stroke.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Criterion validity of the Telephone Interview Form | The agreement between the Telephone Interview Form and face-to-face assessment. | Baseline, 3 days after baseline, 6 days after baseline | 
| Inter-rater reliability of the Telephone Interview Form | The agreement of the Telephone Interview Form when administrated by two different rates | 3 days after baseline, 6 days after baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sensitivity of Telephone Interview Form | Sensitivity of Telephone Interview Form when administered by telephone compared with face-to-face at various cut-off values | 3 days after baseline, 6 days after baseline | 
| Specificity of Telephone Interview Form | Specificity of Telephone Interview Form when administered by telephone compared with face-to-face at various cut-off values | 3 days after baseline, 6 days after baseline | 
| Internal consistency reliability of Barthel Index questionaire in Telephone Interview Form | Internal consistency reliability of Barthel Index questionaire will be evaluated. | Baseline, 3 days after baseline, 6 days after baseline | 
| Convergent validity of Telephone Interview Form | Relationship between Telephone Interview Form and other scales (i.e. (National Institute of Health stroke scale) | Baseline, 3 days after baseline, 6 days after baseline |
