本研究旨在探討不同背景變項大學生之家庭親子界限與其生涯自我效能間的關係。採用問卷調查的方式，以全國十三所公、私立學校大一到大四學生為研究對象，共計625名，並以「個人基本資料調查表」、「生涯決策自我效能量表」及「家庭親子界限量表」編製成「大學生生涯決策與家庭關係問卷」為本研究工具。調查所得資料以描述性統計、變異數分析、皮爾森積差相關、多元逐步迴歸等統計方法進行處理。研究之主要發現如下： 一、不同性別、年級、生涯發展定向情形之大學生的家庭親子界限有所差異。 二、不同年級、科系、修課狀況（是否雙主修或輔系）、打工經驗、生涯發展定向情形之大學生的生涯自我效能有所差異。再者，不同科系的大學生其生涯自我效能會因為打工經驗的不同而有差異。 三、背景變項與家庭親子界限對於大學生之生涯自我效能具有預測效果 （一）就全體大學生而言，「父子（女）自我認同」是大學男生生涯自我效能最主要的預測變項；「母子（女）自我認同」是大學女生生涯自我效能最主要的預測變項。本研究發現，家庭親子界限變項中同性父母對於孩子的認同是大學生生涯自我效能最主要的預測變項；另外，背景變項中生涯發展定向情形對大學生生涯自我效能最具有預測效果。 （二）不同生涯發展定向的大學生來看，不同背景變項與不同家庭親子界限對其生涯自我效能有不同預測效果。 （三）家庭親子界限對於大學男生之生涯自我效能的預測力大於大學女生。 根據本研究的發現及討論，研究者擬對大學生、父母、學校及輔導人員等相關人員和未來研究者，提出數點建議，以供參考。 / The purpose of this study was to investigate the relationships between the career self-efficacy and family parental boundaries perceived by college students. Six hundred and twenty-five college students completed the Career Decision-making Self Efficacy Scale（CDMSE）developed by Hong-Hui Xie and Parental Relation-Self Boundary Scales. Data obtained was analyzed by deviation, percentage, ANOVA, post Scheffe’s test, Pearson product-moment correlation, and multiple regression. The major findings were summarized as follows: First, college students with different gender, grade, and career decision status or identity development made significant differences on their perceptions of family parental boundaries. Second, there were significant differences in CDMSE among different background variables, including grade, departments, dual-major or minor, part-time job experience, and career decision status or identity development. Third, the self-identity of parents is the best predictor of college students’ career self-efficacy, especially with the same gender as the parent. Fourth, because of the difference of college students’ career decision status or identity development, the prediction of family parental boundaries to the career self-efficacy would be different. Fifth, family parental boundaries had better predictive effect to male students than to female students. According to the conclusions of the main findings, several suggestions are provided for college students, parents, related educators and counselors in the Universities, and future research.
