本研究旨在探討高中職學生（1）親職化表現在不同背景變項者之差異；（2）親職化與身心健康的關係；（3）親職化與自我分化的關係；（4）自我分化與身心健康的關係；（5）親職化、自我分化與身心健康的關係。本研究以臺灣地區高一高二423 名學生為研究對象，所使用的研究工具包括「親職化量表」、「自我分化量表」與「一般健康量表」。本研究主要發現如下：（1）不同性別之高中職學生的親職化表現沒有不同；不同出生序者的「功能性照顧」不同；不同父母婚姻狀況者的「不公平性」不同。（2）高中職學生的親職化與身心健康之間有顯著關係。（3）親職化與自我分化之間有顯著關係。（4）自我分化與身心健康之間有顯著關係。（5）親職化、自我分化與身心健康之間有顯著關係。最後，研究者提出建議，以作為諮商輔導、親職教育方面與未來研究之參考。

The purposes of this study was to investigate: (1) group differences on parentification; (2) correlation between parentification and health; (3) correlation between parentification and self-differentiation; (4) correlation between self-differentiation and health; and (5) correlation among parentification, self-differentiation, and health. The samples comprised of 423 senior high and vocational high school students from six areas across Taiwan. Instruments used in this study included [Parentification Scale], [Self-Differentiation Questionnaire], and [General Health Scale]. The main findings are as follows: (1) No significant gender difference of parentification was found;[instrumental caregiving] was significantly different among groups of different birth order; [unfairness] was significantly different among groups of different parental marital status. (2) Parentification is significantly correlated with health. (3) Parentification is significantly associated with self-differentiation; (4) Self-differentiation are significantly correlated with health; and (5) Parentification, self-differentiation are significantly correlated with health. Implications of the results for counseling and parent education as well as suggestions for future research are proposed.
