PMID 27992024WHAT IT FOUND
A questionnaire about how valve heart disease affects daily life, given by telephone, was easy to use and gave stable answers, but adaptation questions did not work well and it may not detect improvement.
Key findings
01All 86 patients answered every IDCV item, and telephone administration averaged 9.9 minutes.
02Total IDCV scores showed adequate agreement over 7 to 22 days, with an ICC of 0.91.
0332.6% of patients scored in the lowest adaptation range, and 17.4% in the lowest symptom range.

What it does not show
The study included 86 outpatients with mitral or aortic valve disease at one university hospital, and only 70 completed the repeat test, so findings may not apply to other settings or patients. The authors noted no other generic tools were used to assess impact, so convergent validity relied on one general question. Floor effects were present, including 32.6% at the lowest adaptation score, so the instrument may not detect improvement. The adaptation domain items 1 and 8 can be interpreted in more than one way. The article text and table disagree on the daily-activity agreement value (0.76 versus 0.85). Telephone administration was used for both test and repeat test, and the authors recommend further study of this method.
The easy way to misread this
Do not conclude that the questionnaire can show a patient improved after nursing care. Floor effects, including 32.6% in the lowest adaptation score, mean it may not detect improvement, and this study did not test a nursing intervention.
