Results of a panel survey study on bereaved parents are reported. Member and non-member groups, reflecting increasing levels of involvement in Compassionate Friends, are compared for trends in changes in depression and personal growth. While no differences in depression were detected a linear trend was evidenced in personal growth. Those parents who were most involved in the group were more likely to maintain a sense of positive personal change over the one year time span of the study. Reasons for the specific impact of self help group involvement are discussed.
