The objectives of this dissertation were to: (1) discover whether commenters and non-commenters on an international marketing questionnaire differ based on sociodemographic, nationality, and personality characteristics; (2) determine whether commenters with greater life satisfaction are more likely to provide positive comments; (3) determine whether commenters differ in response styles due to their national background; and (4) discover whether commenters differ (based on sociodemo-graphic, nationality, and personality characteristics) in their propensity to comment on the design rather than on other questionnaire issues. An exploratory design was used to satisfy these objectives.
