Perceptual and Motor Skills, v52 n1 p11-15 Feb 1981
Two thousand questionnaires were mailed to respondents allocated among seven treatments. Controls received an initial mailing (questionnaire and cover letter) only. The remaining six treatments varied by number of follow-up mailings and whether another questionnaire copy was included. Results suggest more than one follow-up letter with a questionnaire is needed.
