Developing a scale to measure self-efficacy on asthma teaching for health care providers.
J Asthma. 2009 Mar; 46(2):113-7.JA

Abstract

BACKGROUND

A number of educational programs have focused on promoting the knowledge of asthma to health care professionals, but not teaching competency. Increasing the cognition of self-efficacy on patient teaching could enhance the competency in teaching for patients with asthma. However, at present we do not have an appropriate tool to measure self-efficacy on asthma teaching for health care providers.

OBJECTIVES

The aim of this study was to evaluate construct validity by Factor analysis and investigating dimensionality by Rasch analysis of a self-efficacy on asthma teaching scale (SEATs) among nurses in Taiwan.

PARTICIPANTS

A total of 281 nurses from 3 medical centers volunteered to participate and complete the SEATs.

METHODS

A 20-item SEATs was developed including self-efficacy of general teaching and self-efficacy of specific asthma-related teaching. Instrument reliability and validity are examined by classical testing theory (item analysis, internal consistency, content validity, and construct validity). To examine whether each item in the SEATs fits the unidimensionality in the Rasch model, the Winsteps program was used to assess item difficulty, scale unidimensionality, item separation, and linearity.

RESULTS

SEATs has good content validity, internal consistency, and construct validity. Rasch analysis revealed that three items were problematic and need to be re-examined in further study.

CONCLUSION

The first version of SEATs has an acceptable psychometric property to evaluate the asthma teaching efficacy of nurses, although three items were INFIT according to Rasch analysis. A different population of nurses should be recruited to further refine this tool. SEATs could be used as an outcome measure for further program evaluation.
