Psychometric characteristics of turkish version of parental attitudes towards childhood vaccines (PACV) scale [Ebeveynlerin çocukluk aşilarina yönelik tutumlari (PACV) ölçeğinin türkçe sürümünün psikometrik özellikleri]

Abstract

INTRODUCTION: Vaccination hesitation is an important public health problem that has increased in recent years. The aim of this study was to determine the psychometric properties of the Turkish version of the Parenting Attitudes towards Childhood Vaccines Scale (PACV). MATERIALS and METHODS: This methodological study was conducted between January-May 2019 with parents of 0-59 months old children (n = 211) who applied to Balıkesir University Health Application and Research Hospital Children's Polyclinic. PACV scale consists of 15 items in four dimensions: behavior, attitude, safety and effectiveness dimensions. Internal consistency (using Cronbach's alpha value) was used in reliability analyzes, structural validity (known groups and confirmatory factor analysis) and discriminant validity were used in validity analyzes. In the confirmatory factor analysis (CFA), the Comparative Compliance Index (BSI-CFI) and RMSEA were used. In the analysis, SS SPSS version 21.0 for Windows program and Lisrel 8.54 statistical package programs were used. RESULTS: 68.2% of the parents were women, 85.3% had sufficient income perception and 68.7% had only one child. The mean age was 30.84±5.15 for parents and 3.24±1.63 for children. Floor and ceiling effects of the scale are within the desired limits. Cronbach's alpha value of the scale was 0.676. Test-retest results are good (ICC: 0.93, p: 0.001). In the explanatory factor analysis, KMO was 0.77 and the total explained variance was 57.41%. In the Confirmatory Factor Analysis, compliance indicators are good (X2 / sd: 1.87, RMSEA: 0.0652, CFI: 0.949, NFI: 0.90). The scale was found to be discriminant according to the validity of known groups. CONCLUSIONS: The PACV scale is a valid and reliable scale adapted to the Turkish population. Parents' Attitudes towards Childhood Vaccines Scale is sufficient and satisfactory in terms of distribution, measurement ability, internal consistency and model fit. Total correlation after overlap correction was found below 30 in questions 7 and 14 and the results must be interpreted with caution. © 2020, Galenos Yayincilik,. All rights reserved.
