手足情深？成年初期的手足關係

Abstract

本研究旨在了解成年初期的手足關係。現今的臺灣社會，少子化趨勢不但導致家庭結構與成員數量明顯改變，也使得手足關係呈現不同以往的面貌。因此，本研究關注以下兩個問題：首先檢視親密與衝突並存的關係，探索成年初期手足關係的主要類型，而後驗證手足結構因素以及朋友關係對於手足關係的影響效果。 本研究利用中央研究院社會學研究所收集之「臺灣青少年成長歷程研究」的長期追蹤資料，合併國三樣本第一波、第四波、第六波及國一樣本第一波、第六波及第八波等共2599個樣本數進行資料分析。先使用潛在類別分析區分出三種類型的手足關係，依據實質內涵分別命名為「緊密型」、「關懷型」及「疏離型」。而後利用多類別邏輯迴歸分析了解手足結構因素及朋友關係對於手足關係的影響效果，其結果顯示，女性、老么及手足數越多者，手足關係則會越緊密，朋友數目維持在一定的範圍值、擁有男女朋友者，其手足關係也傾向較為緊密。

This thesis aims to investigate the characteristics of sibling relationship among Taiwanese youth entering early adulthood. The declining fertility has changed not only the family structure and size but also a variety of family relations. While marital and intergenerational relations have attracted much attention in the academic circle, there are only few studies related to sibling relationship. Therefore, the current study tries to explore the characteristics and patterns of sibling relationship and to examine how the composition of sibling and friendship affect the sibling relationship in early adulthood. The data come from Taiwan Youth Project, including J1 W1, W6, W8, J3 W1, W4 and W6. The sample consists of 2599 Taiwanese respondents. The results of latent class analysis show that there are three types of sibling relationship, named intimate, buddy and apathetic. According to the results of logistic regression analysis, the female respondents are more likely to report having intimate sibling relationship. In terms of sibling structure, the youngest sibling and large sibling size are associated with close relationship. This study also finds that having friends, including peers, boy and girl friends, can increase the closeness of sibling relationship among Taiwanese in their early twenties.
