I'm doing the Master dissertation and some items in my questionnaire need to do the reverse recoding, but after I recode the items, the Cronbach's Alpha is really low about .34.
Could anyone kindly give any advice on what could the problem is and how could I revise it?
Thanks a lot.
IN ORDER for anyone to help, you need to show what was the original questionaires and what is the re-coding. What was the original scale and how was it recoded?
Could be because the covariance of your items is high, or still you have to reduce your questionary.
Paul Louangrath Thank you for your advice.
Thank you a lot for your reply!
My research aims to investigate how individual factors (intrinsic motivation, paradox mindset, task significance, resource available, proactive personality) in total five independent variables impact employee creativity mediated by unlearning(the process employees abandon old out-dated knowledge and skills to learn new ones).
About the construct
IVS:
Intrinsic motivation: 5 items
Cronbach's alpha: .888
paradox mindset: 9 items
Cronbach's alpha: .873
task significance: 4 items
Cronbach's alpha: .724
resource available: 6 items
Cronbach's alpha: .837
proactive personality: 17 items
Cronbach's alpha: .959
Mediator:
unlearning: I have two questions designed for unlearning.
The first question includes 11 items and I did reverse coding. The
Cronbach's alpha: .350
DV:
creativity: 9 items
Cronbach's alpha: .905
All the items and scale were adopted from previous scholar's article.
According to the low alpha, and what I tried to do was adjust the items of unlearning. About reverse recoding, since all my items used 5 point Likert scale, 1-5, totally disagree to totally agree and some items in my scale stated negatively, I did the reverse by simply using spss recode 1-5, 2-4, 3-3. Because in my question, the higher degree of agreement, the higher willingness people want to unlearn.
The reverse coding seemed can not work and if I just tested the items without the ones need to be reversed, the Cronbach's alpha could be better about .678. But will this really correct?
Thank you a lot in advance if you could give me some advice! Thanks!
