Lacanienta and his colleagues (2018) recently reported results of a study of the effect of themes on quality of experience of youths during summer camp activities. Existing literature suggested that theming activity sessions would have a strong main effect. Results, though, revealed an activity-by-theme interaction effect, i.e., themes seem to be effective in some activities but not others. In this follow-up study, we describe results of a secondary analysis revealing significant new insights regarding theme. Adding an indicator of campers’ co-created, lived-experience theme into the models tested substantially clarified how objective theme, lived-experience theme, and activity interact in influencing the quality of structured experiences. This study, then, underscores the importance of including measures of participants’ co-created lived experience as we seek to understand techniques that can be used to enhance the quality of youths’ structured camp experiences.
