Hasta Güvenliğine Yönelik Dillendirme Anketinin Türkçe’ ye Uyarlanması, Geçerlik ve Güvenirlik Çalışması

Abstract

This study was carried out as a methodological design to adapt the “Speaking up about patient safety questionnaire” into Turkish and to establish its validity and reliability. The questionnaire consists of two sub scale and 8 sub dimensions. In order to adapt the questionnaire to Turkish, linguistic validation was completed through translation-back translation procedures. Content validity was determined using the viewpoints of the panel of 6 experts, and computing the content validity index: 1.00. The sample consists of 333 health care professional, including 170 nurses and 163 physicians working at all units (emergency department, intensive care units, operation room, delivery room, outpatient and inpatient clinics) of Gazi University, Health Research and Application Center, Gazi Hospital. Construct validity of the questionnaire was evaluated through exploratory factor analysis and confirmatory factor analysis method for both of the two scale (“Speak Up–Related Behaviour Scale” and the “Speak Up Related Climate Scale”) , each of which includes total 11 items in 3 subscales). The Kaiser-Meyer-Olkin value was good enough for both of the two scales (0,834 and 0,881, respectively), and The Bartlett’s test of sphericity was significant (p<0,05), suggesting that there is substantial correlation in the data. Exploratory factor using principal components analysis and varimax rotation yielded that all factor loadings were above 0.3. Total variance explained was found to be 77. 856% for Speak Up–Related Behaviour, and 76,009% for Speak Up Related Climate. Confirmatory factor analysis results showed that the scale has an acceptable goodness of fit. Cronbach’s alpha (α) values for all sub scales ranged from 0.77 to 0.92, indicating high internal consistency or reliability of total and sub scales. Test-retest reliability results (r=0,987 and r=0,991) were statistically significant (p<0,05). Based on the statistical analysis none of the items was removed from the questionnaire. As a result, this study confirmed that the Speaking Up About Patient Safety Questionnaire, can be utilized as a validated and reliable instrument in Turkish health care contexts.
