Analisi di affidabilità ed esplorazione fattoriale del questionario CAM Health Belief Questionnaire (CHBQ)

Introduction: modern society has an increasingly strong trend in the complementary therapies use, and inevitably affecting the health models, so is strategic to know what the nurses CAM views. Methods:a convenience sample of 415 nurses was used in this survey. CAM Health Belief Questionnaire (CHBQ) was used, an instrument for measuring nurses CAM views, for reliability analysis and structure factorial exploration. Results:cronbach’s was α.79. The item 7 has critical values, Cronbach's alpha if item deleted was .82, corrected item-total correlation was .124, and squared multiple correlation was .228. Hotelling's t-squared test was 327,29 (F = 35.66, P= .000). Determinate R = .023, KMO measure of sampling adequacy p = .838, and Bartlett's test of sphericity with χ2 = 1543,279 (p<0.001). The best model was principal component with Promax rotation at 2 factors, that explains the 58% about total variance. Correlations between factors by Spearman’s ρ was ρ= .190 (p < .001). Discussion:CHBQ reliability is good, but there are critical values for item 7. The two factors model has a good internal consistency, ability to identify two specific dimensions, and explains about total variance. Weak correlation between the factors. Other studies are needed to clarify the critical nature about item 7 and the correlations weakness between the two factors. Conclusions: this CHBQ model need for comparative studies for various statistical parameters, by using larger samples and sampling conducted throughout the country in the several nursing areas.
