OBJECTIVE: To validate a measurement instrument for clean intermittent self-catheterization for patients and health-caregivers.
MATERIAL AND METHODS: Methodological study of instrument validation performed at a Rehabilitation Center in a University hospital for patients submitted to clean intermittent self-catheterization and their health-caregivers. Following ethical criteria, data were collected during interview with nurse staff using a Likert question form containing 16 items with 5 points each: "no confidence"=1, "little confidence"=2, "confident"=3, "very confident"=4 and "completely confident"=5. Questionnaire called "Self- Confident Scale for Clean Intermittent Self-catheterization" (SCSCISC) was constructed based on literature and previously validated (appearance and content).
RESULTS: The instrument was validated by 122 patients and 119 health-caregivers, in a proportion of 15:1. It was observed a good linear association and sample adequacy KMO 0.931 and X2=2881.63, p<0.001. Anti-image matrix showed high values at diagonal suggesting inclusion of all factors. Screen plot analysis showed a suggestion of items maintenance in a single set. It was observed high correlation of all items with the total, alpha-Cronbach 0.944. The same results were obtained in subsamples of patients and health-caregivers.
CONCLUSION: The instrument showed good psychometric adequacy corroborating its use for evaluation of self-confidence during clean intermittent self-catheterization.
