看護学生の精神健康度に影響する実行機能因子の検討

Examination of Executive Function Factors Affecting the Mental Health of Nursing Students

要旨

　目的：看護学生の精神健康度に影響する実行機能因子を明らかにする．

　方法：看護学生184名に精神健康度および実行機能についての自記式質問紙調査を行った．精神健康度（GHQ12）総合得点，うつ症傾向因子得点，社会活動障害因子得点を従属変数，実行機能（BRIEF-A）総合得点を独立変数とした単回帰分析を行った．また，実行機能の2指数（行動制御，メタ認知），9下位因子（抑制，切り換え，情動制御，自己監視，開始，ワーキングメモリ，計画/組織化，タスク監視，資料の整理）の得点を独立変数とした重回帰分析を行った．

　結果：精神健康度に実行機能が影響を及ぼしていた．総合的精神健康度には2指数のうち行動制御指数が影響を及ぼし，9下位因子の中では「情動制御」と「タスク監視」が影響を及ぼしていた．

　結論：看護学生の精神健康状態を良好に保つには，「情動制御」および「タスク監視」の能力を高める必要がある．

　Purpose: We identify executive functioning factors that affect the mental health of nursing students.

　Methods: A self-administered questionnaire on mental health and executive function was administered to 184 nursing students. A single regression analysis was conducted using the total mental health score(GHQ12), depressive tendency factor score, and social activity disorder factor score as dependent variables, and the total executive function(BRIEF-A) as an independent variable. Multiple regression analysis was also conducted using the two indices of executive function(Behavioral Regulation and Metacognition) and nine subfactors(Inhibit, Shift, Emotional Control, Self-Monitor, Initiate, Working Memory, Plan/Organize, Task Monitor, and Organizing Materials) as independent variables.

　Results: Executive function significantly affected mental health. The Behavioral Regulation Index influenced overall mental health, and among the nine sub-factors, "Emotional Control" and "Task Monitor" were especially influential.

　Conclusions: Enhancing their "Emotional Control" and "Task Monitor" abilities is essential to improving the mental health status of nursing students.
