lled MRMDiets. They then
answered the question 'How would you evaluate MRMDiets?' by choosing a 1-7
response on several scales, including Unlikeable-Likable,
Ineffective-Effective, and Not credible-Credible. The researchers averaged
six such scores to give an overall Credibility score, on the 1-7 scale, with

cooperation of the original researchers, they used the sam
