This study investigates whether and how campers differ from each other in terms of perceived constraints and negotiation strategies by recreation specialization level in camping. The concept of recreation specialization has been applied to segment campers particularly via a self-classification measure. An on-site field survey was conducted with campers at three different campgrounds. Study results show that committed (i.e., more specialized) campers tend to perceive leisure constraints less than active and general (i.e., less specialized) campers. However, there were no significant differences between general and active campers. In terms of negotiation strategies, committed campers were more likely to exercise negotiation strategies than the other two specialization groups. Similarly active campers were more interested in using different negotiation strategies than general campers. A concept of effort justification was proposed as a psychological mechanism to explain the results shown in this study. Future research will be beneficial to confirm study findings here in other recreation and tourism settings.
