Upon entry to the trial, participants were asked to identify
parents or significant others who knew them growing
up, who were then approached by the research nurse to
complete a written self-report of their perceptions of the
impact of bipolar disorder on the participants’ development
that included quantitative and qualitative measures.
These were posted out to identified parents with a stamped
return envelope. For this study we examined the qualitative
data in the parental self-reports.
