The lack of reliable and valid evaluation tools targeting Korean nursing students' critical thinking (CT) abilities has been reported as one of the barriers to instructing and evaluating students in undergraduate programs. Yoon's Critical Thinking Disposition (YCTD) instrument was developed for Korean nursing students, but few studies have assessed its validity. This study aimed to validate the YCTD. Specifically, the YCTD was assessed to identify its cross-sectional and longitudinal measurement invariance.
This was a validation study in which a cross-sectional and longitudinal (prenursing and postnursing practicum) survey was used to validate the YCTD using 345 nursing students at three universities in Seoul, Korea. The participants' CT abilities were assessed using the YCTD before and after completing an established pediatric nursing practicum. The validity of the YCTD was estimated and then group invariance test using multigroup confirmatory factor analysis was performed to confirm the measurement compatibility of multigroups.
A test of the seven-factor model showed that the YCTD demonstrated good construct validity. Multigroup confirmatory factor analysis findings for the measurement invariance suggested that this model structure demonstrated strong invariance between groups (i.e., configural, factor loading, and intercept combined) but weak invariance within a group (i.e., configural and factor loading combined).
In general, traditional methods for assessing instrument validity have been less than thorough. In this study, multigroup confirmatory factor analysis using cross-sectional and longitudinal measurement data allowed validation of the YCTD. This study concluded that the YCTD can be used for evaluating Korean nursing students' CT abilities.
This study aimed to investigate critical thinking disposition among nurses working in Public Hospitals in Port-Said Governorate.
A descriptive research design was conducted in this study. Totally 196 respondents were chosen by systemic random sampling, to take part in the study as the sample. Data was collected from April to September in 2015. Tools of data collection: A personal and job characteristics data sheet and California Critical Thinking Disposition Inventory(CCTDI) were used.
The results revealed that the total critical thinking disposition score mean was 257.05 ± 20.16 and the highest score mean was 48.67 ± 6.28 for inquisitiveness subscale, while the lowest score mean was 21.36 ± 7.19 for the truth-seeking subscale. Also, none of the personal & job characteristics showed statistically significant relations with the total critical thinking disposition.
More than three quarters of the nurses had an ambivalent disposition toward critical thinking, and most nurses' scores indicated a negative tendency towards truth-seeking. So the findings pointed for upgrading nurses' critical thinking through educational programs and a need for more problem-based learning with advanced teaching strategies in clinical areas.
