本研究透過量化研究方式，採用青少年研究中常用的自我控制理論，參照學者及研究對青少年偏差行為的分析，以了解隱蔽青年的背景及自我控制與他們進行偏差行為的相互關係，並嘗試解釋現象的成因。本研究以問卷形式成功訪問了12-30歲的女性隱蔽青年211位及男性隱蔽青年377位，其中佔大多數為與家人同住、家庭收入的0，000以上，並擁有高中或大學以上學歷。研究發現有偏差或違法行為的青年，其個人背景與自我控制跟一般青年不盡相同。與一般青年不同的是，體力活動與隱蔽青年的大部份行為並沒有顯著的相關性，然而，有違法行為的隱蔽青年體力活動反而較低，同時，他們的冒險性低，投機性高，自我中心較低，反映他們的違法行為不為求一時、短暫的快樂，或只以個人為優先考慮，反而是經過思考，並且衡量個人的能力或其他環境因素後所作出的行為。由此可見，已有的青年研究結果不足以解釋隱蔽青年的偏差或違法行為，關注隱蔽青年的工作者宜就他們獨特的生活形態及行為模式作出更深入的研究。

As far as public security administration is concemed, Kinmen, an outlying island near mainland China, is a special region which has been controlled by the military for a long period of time. The tight security benefited the archipelago islands. However, as time went by, the public security administration of Kinmen became different from what it used to be due to the policy of three links. The policy of the three links included direct postal, transportation, and trade to mainland China, and cross-strait civil interactions. Since its initiation, the main concems and directions of police public security administration in the areas of smuggling, stowaway, theft, travel disputes etc. were noticeably changed. Deployment of police officers became insufficient due to the massive flow of passengers, and further drained the resources protecting the permanent registered residents on the island. Moreover, the recent dual cross strait interactions and exchanges in Kinmen area were suggested to have worsened the situation by the extending issues ofthe related police public security administration. With the current two-tier system being changed to three-tier system policing, the shortage ofmanpower was likely to result in poor morale among police officers.
