Customer survey results
November 2004, Dina Bianchi
The participants
The customer survey was carried out on the basis of a questionnaire. A total of 200 patients each were selected at random from three different groups:
- Group 1: 1-3 years since starting the Rohner Concept
- Group 2: 4-6 years since starting the Rohner Concept
- Group 3: 7-10 years since starting the Rohner Concept
Of the 600 questionnaires sent out, 154 were returned within the period stipulated, containing sufficient data for the analysis (rate of return 25.6%). No reminder was sent. More than 40 questionaires were completed in each group. This number allowed us to issue an analysis with broad-based conclusions. The data was analyzed using the SPSS statistics program.
