Abstract
Objective:
design and validate a questionnaire to evaluate the knowledge and attitudes
of nurses about the subcutaneous venous reservoir.
Method:
pilot test: 30 specialized care nurses. Main study: 236 nurses of primary and
specialized care. Content validity was evaluated by Lawshe index,
reliability by test-retest, internal consistency by Cronbach alpha, and
construct validity by exploratory factorial analysis.
Results:
Items with a Lawshe index lower than 0.51 were eliminated. In the
test-retest, the intraclass correlation coefficient was higher than 0.75 for
all items. The Cronbach alpha of the attitude questionnaire reached 0.865.
The Cronbach alpha value for knowledge was 0.750. The exploratory factor
analysis identified a set of four dimensions for each part that explain 64%
(attitude) to 80% (knowledge) of variability.
Conclusion:
the analysis of the reliability and validity of the questionnaire supports
its use as an instrument to assess the knowledge and attitudes of nurses
towards the subcutaneous venous reservoir.
