초록

본 연구는 주의편향수정(Attention Bias Modification; ABM) 훈련에서 지시문(명시형, 암묵형)과 자극제시 시간(300 ms, 500 ms)에 따른 ABM 훈련의 효과를 대학생 사회불안 증상 집단을 대상으로 확인하고자 하였다. 부산 소재 대학의 대학생을 대상으로 사회적 회피 및 불편감 척도(Social Avoidance and Distress Scale; SADS)가 82점 이상이면서 주의편향 점수(Attention Bias Score; ABS)가 0보다 큰 참가자를 ABM 훈련 대상자로 선정하였다. 훈련 집단은 명시형-300 ms 집단(n=10), 명시형-500 ms 집단(n=8), 암묵형-300 ms 집단(n=8), 암묵형-500 ms 집단(n=7)이었다. 암묵형 지시문 집단에는 ABM 훈련 실시 절차 정보만을 제공하였다. 명시형 지시문 집단에는 추가로 훈련 조작(탐침이 항상 중성 자극이 나타났던 위치에 나타남)에 대한 정보를 제공하였다. 그리고 집단에 따라 300 ms 혹은 500 ms의 자극제시 시간을 사용하였다. 통제 집단은 통제-300 ms 집단(n=5), 통제-500 ms 집단(n=7)으로 구성하여 중성-중성 자극 쌍만을 제시하였다. 역시나 집단에 따라 300 ms 혹은 500 ms의 자극제시 시간을 사용하였다. 총 8회기의 ABM 훈련을 완료하고 SADS와 ABS를 재측정하였다. 분석 결과, ABM 훈련 효과는 지시문 집단에서만 나타났다. ABS 감소는 세 집단(명시형 지시문, 암묵형 지시문, 통제)에서 모두 유의하였지만, 명시형 지시문 집단의 처치 효과가 가장 효과적이었다. SADS 점수 감소는 명시형 지시문 집단에서만 유의하였다. 자극제시 시간에 따른 ABM 훈련 효과의 차이는 나타나지 않았다. 본 연구 결과는 명시형 지시문이 암묵형 지시문에 비해 ABM 훈련 효과를 증진시킬 가능성이 있음을 시사한다.

This study was conducted to examine the effects of instruction (explicit, implicit) and stimulus presentation time (300 ms, 500 ms) in ABM training. According to the Social Avoidance and Distress Scale (SADS) and the attention bias score (ABS), 60 undergraduate students were selected. All participants' SADS scores were above 82 and their ABS score was greater than 0. The training group was explicit-300 ms training group (n=10), explicit-500 ms training group (n=10), implicit-300 ms training group (n=10) and implicit-500 ms training group (n=10). In the implicit instruction group, only information about procedure was included. In the explicit instruction group, additional information about training manipulation (the probe always presented at the location of the preceding neutral stimuli) was provided. The control group were placebo-300 ms control group(n=10) and placebo-500 ms control group(n=10). After 8 sessions of training, the effect was only found in instruction conditions. The explicit training group showed significantly decreased SADS after training. ABS changed significantly in all three conditions but the treatment effect was most effective in the explicit instruction condition. No significant effect was found in the stimulus presentation time. These results suggest that explicit instruction might promote the effect of ABM training compared to implicit instruction.
