title: Interpretive subgroup analysis extends modified grounded theory research findings in oncologic music therapy.
abstract: Following an investigation into oncologic patients' experiences of the helpfulness of music therapy (O'Callaghan & McDermott, 2004), it was considered that examining relationships between specific patient characteristics and their responses could yield further interesting understandings. "Interpretative subgroup analysis" is introduced, which adapts principles of subgroup analysis in quantitative research to textual data analysis. Anonymous written responses from 128 oncologic patients were analyzed to compare responses from (a) those that had one music therapy session with those who had more than one session, (b) males and females, and (c) middle and older aged respondents. The number of music therapy sessions had scant effect on reported music therapy experiences, and males were much more likely to return questionnaires but much less likely to participate. Unlike some females, males always described positive affective responses when experiencing both sad and positive memories. Variations in the middle and older aged subgroups were evident in type of affective response, and emphases in descriptions of memories and music therapy's effect. Implications of these findings for music therapy practice are considered. Interpretive subgroup analysis is recommended for extending understanding of subjective within group experiences in music therapy research incorporating a grounded theory approach and large enough samples.
