2003年《兒童及少年福利法》加強兒童保護措施和提高相關罰則。本文分析兒少法對親子互動模式、休閒活動類型及休閒措施需求的影響。發現兒少法實施對親子互動爲感情融洽經常聊天和少年親社會(prosociality)評價之機率均有正面影響。少年困擾時找父母和兄弟姐妹討論的可能性較高。感情融洽經常聊天的上升主要發生在父母學歷爲高中職以下的家庭。另外，兒少法實施分別與球類運動、看電影、家中上網呈負向關係，與登山郊遊露營、看電視及錄影帶，以及營隊活動和圖書館休閒措施需求呈正向關係。本文亦討論兒少法實施讓親子互動爲感情融洽經常聊天機率上升的途徑，可能是親子共同從事休閒活動的可能性與品質均上升，代表親子互動的頻率提高，進而提升親子關係。

The 2003 Children and Youth Welfare Act strengthened the child protection regulations and raised the related penalties for violations. This paper studies the effect of the Act on parent-child interaction, types of leisure activity and the demands on leisure facilities. Results indicate that after the implementation of the Act, both emotional harmony and frequent parent-child chats, along with the evaluation of overall pro-sociality were increased. The adolescents were more likely to talk with their parents or siblings when they felt troubled. The increase in this parent-child interaction was mainly from the families where parents’ education level was high school or below. Moreover, the implementation of the Act was negatively related to the likelihoods of engaging in playing sports activities, watching movies outside the home, and surfing the internet at home, and positively related to the likelihoods of engaging in outdoor activities (e.g., hiking or camping) and watching TV or video at home, and this increased demands for outdoor camping activity and indoor library recreation. This paper also discusses the possible reasons why the Act positively affects the likelihood of emotional harmony and frequent chats. The results show that the likelihood and quality of parents and children engaging in leisure activities together increased the frequency of parent-child interaction, leading to a better parent-child relationship.
