Re the telephone usage of SF36, I remember reading about a study that found that telephone interviewing (without changing the words) produced slightly different results from postal - such as better completion rate (not surprising); and higher general health status, I think.
Below is a quick medline search re interview vs telephone vs postal survey results.
