Dear Andy,

Thanks for your advice,I have posted my output  comparing the result of two models in this attachment.
regards to thid fact that mean is not equal to variance in my dateset do you think it is obligation to use NB regression for me?
it should be noted my samples are 450 respandants.

I am really appreciated
