Critical thinking skills of undergraduate nursing students: description and demographic predictors.

AIM: This study investigated the critical thinking skills among undergraduate nursing students in Australia to obtain a profile and determine demographic predictors of critical thinking. BACKGROUND: There is universal agreement that being a critical thinker is an outcome requirement for many accreditation and registering nursing bodies. Most studies provide descriptive statistical information about critical thinking skills while some have studied the changes in critical thinking after an intervention. Limited research about factors that predict critical thinking skills is available. METHODS: A cross-sectional descriptive study was conducted using convenience sampling. Two hundred and sixty-nine students were recruited across three years of an undergraduate programme in 2009. Most students' age ranged from under 20 to 34 years (58%), 87% were female, 91% were Australian and 23% of first and second year students had nursing associated experience external to the university. Data about critical thinking skills were collected via the Health Science Reasoning Test (HSRT). Linear regression analysis investigated the predictors of nursing students' critical thinking skills. RESULTS: The students in third year had a profile of critical thinking skills comparable with HSRT norms. Year of study predicted higher critical thinking scores for all domains (p<0.001) except the subscale, analysis. Nationality predicted higher scores for total CT skill scores (p<0.001) and subscales, inductive (p=0.001) and deductive reasoning (p=0.001). Nursing associated experience predicted higher scores for the subscale, analysis (p<0.001). Age and gender were not predictive. However, these demographic predictors only accounted for a small variance obtained for the domains of CT skills. CONCLUSION: An understanding of factors that predict nursing students' CT skills is required. Despite this study finding a number of significant predictors of nursing students' CT skills, there are others yet to be understood. Future research is recommended exploring explicit CT instructional approaches and nursing students' CT skills.

Examining the impact of high and medium fidelity simulation experiences on nursing students' knowledge acquisition.

AIM: This paper describes a study that measured and compared knowledge acquisition in nursing students exposed to medium or high fidelity human patient simulation manikins. BACKGROUND: In Australia and internationally the use of simulated learning environments has escalated. Simulation requires a significant investment of time and money and in a period of economic rationalisation this investment must be justified. Assessment of knowledge acquisition with multiple choice questions is the most common approach used to determine the effectiveness of simulation experiences. METHOD: This study was conducted in an Australian school of nursing; 84 third year nursing students participated. A quasi-experimental design was used to evaluate the effect of the level of manikin fidelity on knowledge acquisition. Data were collected at three points in time: prior to the simulation, immediately following and two weeks later. RESULTS: Differences in mean scores between the control (medium fidelity) and experimental (high fidelity) groups for Tests 1, 2 and 3 were calculated using independent t tests and were not statistically significant. Analysis of covariance (ANCOVA) was conducted to determine whether changes in knowledge scores occurred over time and, while an improvement in scores was observed, it was not statistically significant. CONCLUSION: The results of this study raise questions about the value of investing in expensive simulation modalities when the increased costs associated with high fidelity manikins may not be justified by a concomitant increase learning outcomes. This study also suggests that multiple choice questions may not be the most appropriate measure of simulation effectiveness.

The development and psychometric testing of the Satisfaction with Simulation Experience Scale.

AIM: This paper reports the development and psychometric testing of the Satisfaction with Simulation Experience Scale, an instrument designed to measure and compare differences in satisfaction levels between nursing students exposed to medium and high fidelity human patient simulation manikins. BACKGROUND: Student satisfaction is important to engaged and meaningful learning and it facilitates active and purposeful participation in simulation experiences. There are suggestions that student satisfaction may have some correlation with performance. Few studies have explored in a rigorous way the impact of manikin fidelity on nursing students' satisfaction with simulation experiences. METHOD: The items for the Satisfaction with Simulation Experience Scale were identified following a critical review of the literature. Content validly was established by use of an expert panel. During 2009 and 2010 the instrument was tested with second year (n=268) and third year nursing students (n=76) from one Australian university. Exploratory factor analysis with varimax rotation was used to determine construct validity and Cronbach's coefficient alpha determined the scale's internal consistency reliability. Differences in satisfaction levels between groups were analysed using an independent t test. Responses to an open ended question were categorised using thematic content analysis. RESULTS: The scale demonstrated satisfactory internal consistency (alpha 0.77). Exploratory factor analysis yielded a three-component structure termed Debriefing and Reflection, Clinical Reasoning, and Clinical Learning; each subscale demonstrated high internal consistency: 0.94; 0.86; 0.85 respectively. Mean satisfaction scores were high for each group. However, statistically significant differences were not apparent between second or third year students exposed to medium and high fidelity manikins. Content analysis identified 13 main categories including supplementing versus replacing clinical placements and the need for increased exposure to simulation sessions. CONCLUSION: The results of this study indicate that simulation is highly valued by students, irrespective of the level of fidelity. This raises questions about the value of investing in expensive simulation modalities. The Satisfaction with Simulation Experience Scale was reliable and valid for this cohort. Further research in different contexts would be valuable in extending upon this work.

Implementing a clinical competency assessment model that promotes critical reflection and ensures nursing graduates' readiness for professional practice.

AIM: This paper describes the design, implementation and evaluation of the Structured Observation and Assessment of Practice (SOAP), a model used to assess third year undergraduate nursing students' clinical competence. BACKGROUND: Competence is a complex concept that is difficult to define and measure. The assessment of nursing students' clinical competence has confronted universities with problems of validity, reliability, subjectivity and bias for many years. This presents particular problems in nursing as patient outcomes may be compromised by incompetent practice. Too often assessments of nursing students' competence comprise brief assessments of psychomotor skills, vague global assessment of generic skills/attributes or assessments undertaken in simulated laboratory settings rather than the real world of practice. METHODS: The Structured Observation and Assessment of Practice (SOAP), is a full day holistic practice-driven clinical competence assessment approach that motivates nursing students' learning, promotes critical reflection and confirms graduates' readiness for professional practice. This model was introduced in 2004 and since then 1031 students have been assessed. Quantitative and qualitative data has been collected via an anonymous online evaluation. RESULTS: Survey results have been statistically analysed using The Statistical Package for the Social Sciences (SPSS) (Version 13) with exploratory factor analysis employed to ascertain construct validity. This paper will report on the four components that showed acceptable factor loadings and that together accounted for 77.65 per cent of the variance: perceived learning outcomes, consistency with general clinical performance, quality of assessors, and anxiety/stress impact. CONCLUSION: The results of the SOAP approach supports the premise that quality clinical assessment requires nursing students' exposure to complex challenges undertaken in authentic clinical contexts, observed by registered nurses who are trained as assessors and have a strong educational and clinical background.
