Essay / Likert Scales: Composition, Opportunities and Limitations
Performance analysis and quality monitoring are essential to any organization to ensure that programs and different organizational activities are all aligned and operating according to the desired plan. One of the best and commonly used indications is patient satisfaction and feedback; hence the widespread use of surveying techniques. Likert scales, in particular, have been very useful in this regard due to their simplicity, ease of completion and interpretation, and high specificity regarding the aspects measured. In fact, a survey before and after implementing changes is very useful because it indicates the level of success or failure. So, what is the composition of a Likert scale and what are the opportunities and limitations of this survey instrument? Origin and Composition of the Likert Scale The way attitude research has changed significantly since Likert, R. introduced his scale in 1932 (Edmondson, Edwards, & Boyer, 2012). It uses the usual bipolar response points that almost everyone knows today. According to Edmondson, Edwards, and Boyer (2012), the Likert scale was found to be more reliable and used only half the number of items used by other popular methods at the time of its introduction. Additionally, in most cases the scale does not require judges, which adds to its simplicity. Since then, the Likert scale has become very popular and many modifications have been added to improve the accuracy of the results (Edmondson, Edwards, & Boyer, 2012). The Likert scale is composed of the analysis of a series of statements with which respondents agree or disagree to varying degrees (Albaum, 1997). According to Edmondson, Edwards and Boyer (2012), the Likert scale was originally composed of 4 different components. The first one was strictly a yes/no/...... middle of paper ...... the challenges ahead in healthcare, organizations need to make the best use of all resources including consumer attitudes and judgments. , J.
