기존의 연구들은 자기보고 도구에 의존하는 방식으로 자해 행동(자살시도, 비자살적 자해)의 설명과 예측에 어려움을 겪었다. 본 연구는 자해행동에 대한 암묵적 연합을 측정하는 도구를 소개하고 이를 자살 위기 측정에 활용할 수 있는 가능성을 탐색하였다. 암묵적 연합 연구 결과를 자살 시도와 비자살적 자해로 구분하여 리뷰한 결과, 행동 유무에 따른 암묵적 연합의 차이가 관찰되었으며 치료적 개입 후 증상의 변화에 암묵적 연합의 변화가 동반되는 현상이 관찰되었다. 암묵적 연합은 자기보고, 과거 자해행동 등에 더해 추가적인 설명력을 가졌다. 끝으로 연구의 제한점을 논의하고 추후 연구 방향을 제언하였다.
Previous studies in self injurious behavior based on self-report have severe limitations in predicting and explaining self injurious behavior. To overcome the limitation of self-report and improve risk assessment, this study seeks more objective markers of suicidal risk via a computerized behavioral test such as the Implicit Association Test(IAT) which measures implicit associations. Studies measure implicit associations organized into suicidal behavior(suicide attempt) and non-suicidal self injurious behavior(NSSI) category. Implicit measures of self injurious behavior-relevant associations were consistent with hypothesis for the existence of behavior. Therapeutic interventions affected implicit measures for self injurious behavior. Implicit measures had incremental predictive value for certain self injurious behaviors. Limitations with implicit measures are discussed and future study direction are suggested.
