Although youth with internalizing symptoms experience friendship difficulties, surprisingly little is known about their problematic interpersonal behaviors. The current observational study identifies a new construct, conversational self-focus, defined as the tendency to direct the focus of conversations to the self and away from others. Results indicated that youth with internalizing symptoms were especially likely to engage in self-focus when discussing problems with friends and that doing so was related to their friends perceiving the relationship as lower in quality, particularly helping. Content analyses further indicated that self-focused youth talked about themselves in ways that were distracting from their friends’ problems and that they changed the subject abruptly. Last, conversational self-focus was not redundant with related constructs of rumination and self-disclosure. This research highlights the importance of intervention efforts aimed at teaching self-focused youth ways to cope with distress that are more effective and will not damage their friendships.
