I want to conduct a survey on the external motivational factors for the adoption of sound Hospital Waste Management. The nursing staff form the respondents. I want to be able to conduct EFA on the responses to identify the groups/factors under which the variables/statement would lie. The scale to measure the responses consists of YES/NO in the beginning followed by the strength of this response in the form of a Likert scale. Its something like:-
1. Govt Regulations should be followed for HWM Yes/No VL L M H VH
here VL= very low L=low M= medium H=high VH=very high
My questions are
a. Is this approach correct?
b. How should I assign scores to the responses for EFA?
The way I see it there would be five unique scores each for a combination of Yes/No and the corresponding strength. So should I use the following scores?
Yes/VL =1; Yes/L=2; Yes/M=3; Yes/H=4; Yes/VH=5; No/VL=6; No/L=7;.......
I know it sounds complicated. Your feedback might help me approach my research in a better way
Thx
I think this is not appropriate to do the EFA for your measurement. I just wonder why do you use Yes/NO and five likert scale. ? Is giving any meaning over there?
I could suggest you can use standard measure of Likert scale range from 1 to 5 or else 1 to 7. Then respondents will answer from strongly disagree to strongly agree. This will include your yes or no answers as well and helps EFA works.
I just wanted to have a wider range of responses. The largest group of respondents for the EFA consists of trainee nurses as they are easier to approach in their class rooms. Once I have the results I will proceed with the main survey consisting of reduced number of variables nicely positioned under their respective factor headings. The regular experienced nursing staff would form the main group for this survey and I will use the regular 5 point Likert scale ranging from Strongly Disagree to Strongly Agree to gauge the responses.
I am extending extra effort because I want the survey questionnaire to be crisp and concise before I target the experienced nurses. It's very difficult to approach them as there are are 160 of them stationed across 19 Wards working in three different shifts. Getting these responses is also time consuming as I have to translate every item from English to Urdu/Punjabi and explain it in detail. Hope you have got the picture.
