| Summary: | 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.
