This study aimed at understanding the client experience when cognitive therapy for depression was applied via in-vivo counseling through world-wide web. Three female clients with depressive mood were invited to participate in 9, 12, or 23 on-line counseling sessions. Qualitative methodology was used and content analysis was applied.
