You are conducting a survey based study that seeks to examine the satisfaction of members at health clubs in your geographic area. In an attempt to save time, you find a previously validated and published questionnaire from a somewhat similar study performed at physical therapy clinics. What should your next step be?

a. Validate the questionnaire again, since there are population differences

b. Perform a factor analysis to reduce the questionnaire item number

c. Prepare your cover letter/introductory email

d. Send out your questionnaire
