본 연구는 성인을 대상으로 주의력결핍 및 과잉행동장애(Attention-Deficit/Hyperactivity Disorder: 이하 ADHD)와 이상섭식행동의 관계에서 정서조절곤란의 효과를 살펴보고자 하였다. 구체적으로 ADHD가 섭식 제한, 정서적 섭식, 외부적 섭식에 이르는 직접 경로와 정서조절곤란이 매개하는 경로를 포함하는 최적 모형을 찾아 변인간 관계를 검증하였다. 이를 위하여 20∼60대 성인을 대상으로 아동기 ADHD, 성인기 ADHD, 이상섭식행동, 정서조절곤란을 측정하는 설문을 실시한 뒤, 응답의 일관성이 있는 자료 289부(남 132명, 여 157명, 연령평균: 38.91세)를 분석하였다. 연구모형은 측정모형 검증과 구조모형 검증의 2단계를 거쳐 진행되었다. 먼저, 측정모형의 신뢰성과 타당성을 검토한 뒤, 측정 자료의 특성을 기술하고 참가자 특성에 따른 차이를 검증하였다. 그 결과, ADHD 유병률의 성차를 제외하고는 개인특성의 차이가 없었다. 이후 가설검증을 위해 위계적 회귀분석과 경로분석을 실시한 결과, ADHD는 이상섭식행동 중 정서적 섭식, 외부적 섭식과 관련이 있었으며, 각 경로는 정서조절곤란에 의해 매개되었다. ADHD 성향을 가진 사람이 내외적 자극에 의한 충동적 섭식을 반복할 위험이 있으며, 그 치료와 예방에 있어서 정서조절 문제를 다루는 것이 중요함을 제안하며, 연구의 한계점과 추후 연구를 제안하였다.
This study examined the relationship between ADHD and disordered eating behaviors, and the extent to which emotional dysregulation mediates the impact of ADHD on eating styles. Two hundred and eighty nine respondents aged 20 to 69 (132 males, 157 females) completed surveys that measured levels of ADHD in children and adults, emotional dysregulation, and disordered eating(restrained, emotional, and external eating). A two-stage approach was used for data-analysis. First, the measurement model was refined by preliminary tests of reliability and validity. Second, the theoretical model was composed based on the results of a regression analysis, and tested with competing models using a path analysis. Results indicated a significant relationship exists between ADHD and emotional and external eating, but does not exist between ADHD and restrained eating. In addition, emotional dysregulation mediated the paths connecting ADHD to emotional and external eating. Current results suggest emotional dysregulation has a potential effect on the comobidity of ADHD and eating disorders.
