A psychologist who conducts qualitative research on social support and major life stresses is interested in how parents cope with the death of a young child. He decides to research the use of Internet sources of support. Posing as a parent who has recently lost a child, he subscribes to several listservs and participates in discussions in several chat rooms. He prints postings and discussions for his data analyses and quotes from these transcripts in his publications. What ethical concerns exist? What additional issues arise if the psychologist harvests the lists, not as a participant, but by accessing archives?
