Need help with missing values

Participants completed 2 questionnaires at Time 1, and each questionnaire is being scored for empathy. Because of recording issues, I do not have an empathy score for some participants for Questionnaire A. If there is a meaningful correlation between empathy scores on Questionnaire A and Questionnaire B is it possible to impute scores for Questionnaire A from the mean scores on Questionnaire B? How strong would the correlation need to be for this to be appropriate? Otherwise what are my options for dealing with those missing values?

Thanks for your help!
