COVID-19 대유행은 음식 배달 서비스(FDS) 이용 증가를 초래하였으며, 건강에 해로운 식습관 형성 및 지나친 포장용기 사용으로 인한 환경 문제 등 지속가능하지 않은 행동 습관을 촉진하였다. 본 연구는 이에 대해 대체 행동 및 지속가능성 지향 동기를 촉진하기 위한 행동 변화 개입을 디자인하였다. 예비 조사를 통해 음식 배달 서비스에 대한 인식을 수집하고, 개입 대상 그룹을 식별하기 위해 페르소나를 생성하였다. 4명의 참가자와의 인터뷰를 통해 맞춤형전략을 개발하였다. 행동 변화 개입 디자인은 대체 행동의 목표를 설정하고 추적하기 위해 빙고 게임을 차용하였으며, 강화와 보상을 제공하기 위해 보너스 반응 비용 체계를 도입하였다. 개입의 효과는 질적 및 양적 데이터를 통해 평가되었다. 개입은 FDS 사용 빈도의 감소와 참가자들의 지속가능성 인식의 향상을 보여주었다. The COVID-19 pandemic boosted food delivery service (FDS) usage, causing unsustainable habits and environmental concerns. This study aims to develop a behavioural change intervention to promote sustainability-oriented motivations. The intervention involved the use of a bingo board to set and track goals for alternative behaviours. The intervention showed a reduction in FDS use frequency and an improvement in participants' sustainability awareness. The bingo board provided a sense of accomplishment and satisfaction, acting as reinforcement, while the bonus response cost served as both a reinforcement and a punishment. This study provides insights into the need for developing design-led interventions for promoting sustainable behaviours.

Objective: This study aimed to investigate the moderated-moderated mediating effects of children's media content selection and parental restrictive media mediation on the relationship between children's screen media time and executive function difficulties. Methods: A total of 693 parents of children aged 5~6 years participated in this study and were asked to answer all survey questions. The data were analyzed by descriptive statistics and correlation analysis using SPSS 27.0. Model 11 of PROCESS macro 4.3 was used to examine the moderated-moderated mediation model. Children’s gender, age, childcare enrollment status, and household income were included in the analyses as covariates. Results: The moderated-moderated mediating effects of children's media content selection and parental restrictive media mediation were found to be significant. Specifically, bedtime mediated the relationship between screen media time and executive function difficulties only when parents did not appropriately implement restrictive mediation and children freely selected media content. Conclusion/Implications: It is recommended that parents understand the importance of implementing restrictive media mediation and selecting appropriate media contents for their child to prevent executive function difficulties in early childhood. Also, child education or day-care centers should offer education program about appropriate media use to reach more parents.
