國中生自傷行爲現況及其與述情障礙之關聯研究——以臺灣北部國中生爲例

Nonsuicidal Self-Injury and Related to Alexithymia among Junior High School Students in Northern Taiwan

本研究旨在了解國中生自傷行為之現況，並檢驗述情障礙與自傷行為間之關聯性。本研究以臺灣北部地區國中生為研究對象，採分層叢集立意取樣方式進行抽樣，共取得1，060名有效樣本，並施以「自傷行為量表」與「述情障礙量表」進行分析。本研究發現如下：（1）自傷行為國中生占總人數百分比為40.91%，且其中偶發自傷行為占總人數百分比19.32%、反覆自傷行為占21.59%。（2）有自傷行為的國中生比起沒有自傷行為的國中生，述情障礙量表總分及難以辨識感受分量表和難以描述感受分量表總分皆顯著較高，但外化式思考分量表總分則無顯著差異。（3）述情障礙量表總分及難以辨識感覺和難以描述感覺分量表總分，皆與自傷行為頻率、反覆自傷及多重自傷方法間有顯著正相關，但外化式思考分量表則無。研究者根據研究結果提出討論與建議，以供中等教育實務工作者及未來研究參考。

The study aimed to explore the prevalence of nonsuicidal self-injury (NSSI) and its relationship with alexithymia among junior high school students in the north of Taiwan. The study adopted the stratified sampling method, with 1, 060 participants (Mage = 14.66, SD = 0.86 years). The results showed that the prevalence of NSSI was 40.91%, including 19.32% episodic NSSI and 21.59% repetitive NSSI. Compared to the non-NSSI group, the total scores of alexithymia and the subscale scores of difficulties identifying feelings and difficulty describing feelings was significantly higher in those who have engaged NSSI, respectively. However, the subscale scores of externally-oriented thinking appeared to have no difference between the non-NSSI and NSSI groups. Moreover, the frequency of NSSI, repetitive and multiple ways of NSSI was significantly positively correlated with the total score of alexithymia and the subscale score of difficulty identifying feelings and difficulty describing feelings, respectively, but were not significantly related to externally-oriented thinking. The study provided suggestions for future studies and educational implications for secondary education.
