The Development of a Self-perception of Pregnants Scale and its Psychometric Features
Özet
Objectives: The aim of this study is to develop the scale of Self-perception of Pregnants, and to determine validity and reliability of that scale. Methods: The sample of present study consists of 326 volunteer pregnants who applied for their routine controls at Ondokuz Mayis University, Faculty of Medicine. The Cronbach alpha value is found by analyzing inner consistency to determine the reliability of the scale. In addition, explanatory factor analysis is used for the construct validity of the scale. Results: Exploratory factor analysis revealed that the structure of scale is involved in 12 items and two components. The Cronbach Alpha reliability coefficient calculated for the first factor was found to be 0.86; and the Cronbach Alpha was 0.75 for the second factor. A total of 12 items are identified by factor analysis in which the 33.28% of the total variance is explained with factor 1, and the 53.83% of the total variance is explained with factor 2. It is indicated that the Kaiser-Meyer-Olkin coefficient of the scale is 0.86, and the factor loads are between 0.38 and 0.95. The Chi-square value is found to be significant in factor analysis (chi(2)= 128.117; sd= 50, p= 0.00). According to confirmatory factor analysis' results, GFI (. 92), NFI (. 94), RMSEA (. 078), CFI (. 96), AGFI (. 88) as goodness fit indices were calculated and the findings indicated the model was fit to observed structure. Conclusion: The findings of reliability studies, exploratory and confirmatory factor analysis studies revealed that the scale was reliable and valid data collection tool to identify the pregnants' self-perception level.
