The Internet and the quality of life of the elderly: a qualitative and quantitative dilemma

About

Computers with Internet access and training were given to Elderly Australians in a project to assess the impact on their quality of life. The interviews indicated that they loved the learning experience, were proud of their achievement and found the Internet to be a source of wonder and amazement as well as a good way to stay in touch with their loved ones. However, the questionnaire survey showed that their quality of life had decreased over the time, both absolutely and relative to a control group. What does this tell us about the Elderly and the Internet, and what does it tell us about qualitative and quantitative research?
