Construction, validation and reliability of an instrument for evaluation and evolution of chronic wounds

construct and validate an instrument for evaluation and evolution of chronic wounds. The content and apparent validities were appreciated by experts, the reliability by the analysis of concordance between evaluators using the interclass correlation coefficient and to verify the construct validity was used the instrument Pressure Ulcer Scale for Healing. the analysis of the scores of the instrument by the ICC showed an excellent and significant correlation (K = 0.914) and to verify the construct validity of the instrument, the Pearson correlation coefficient, whose result was 0.573, showed a statistically significant and strong correlation between the scores instrument and the Pressure Ulcer Scale for Healing. Most of the concordances of the items were classified as moderate or substantial. The instrument is valid and reliable. It is suggest longitudinal studies in larger populations, semantic validation in a sample of nurses, and an illustrative guide to standardize concepts in order to improve the evaluation of metric properties
