Development of a prenatal smoking cessation counseling scale for public health nurses in Japan

摘要

INTRODUCTION:This study aimed to develop a scale to measure prenatal smoking cessation counseling for Japanese public health nurses (PHNs).METHODS:A cross-sectional study was conducted via an anonymous, self-administered questionnaire. The sample included 1933 PHNs working in 424 municipal health centers nationwide, which were randomly selected. We created the draft scale based on semi-structured interviews, previous studies, and preliminary survey. Additionally, we conducted back translation for English version of the draft scale to be applicable in English countries. The analytic strategy consisted of item analysis, exploratory factor analysis, and differentiation by 'known groups'.RESULTS:A total of 550 responses (28.5%) were included in the analysis. Most of the respondents were female (98.2%) and the mean age was 37.5±9.37 years. In the exploratory factor analysis, two factors were extracted and the factor loadings for all items were greater than 0.40. The first factor with eleven items was named as 'basic counseling' and the second factor with seven items was named as 'advanced counseling'. The Cronbach's alpha of the scale was 0.918, and the cumulative contribution was 44.908%. Multiple comparisons by experience years working as a PHN revealed significant differences in the scale and two factors.CONCLUSIONS:In this study, we initially developed the prenatal smoking cessation counseling scale for Japanese PHNs, and the reliability and validity of the scale were considered to be acceptable.? 2021 Li M. et al.
