Abstract The family is the fundamental unit in society and perhaps the oldest and most important of all human institutions. Several studies have indicated a positive correlation between strong, successful families and family participation in outdoor recreational activities. This paper addresses the role of structured outdoor recreation programming in family enrichment. Findings from two studies based in the United States are presented: one on the effect of a one-day family outdoor adventure program on parental and child perceptions of family functioning and the other from a qualitative inquiry into the meaning of family residential camping experiences. The first study collected both quantitative and qualitative data from 24 families who participated in an 8-hour outdoor adventure program. The second study utilized structured interviews with 11 families participating in a residential camp experience. Findings from both studies demonstrate that structured outdoor family recreation programming has a strong positive relationship with family strength. Furthermore, findings indicate that the type of outdoor adventure activities being used in the treatment of dysfunctional and maladaptive families is also effective in providing family enrichment experiences. 相似文献
