식료품 구매의 건강과 환경 지속 가능성을 개선하기 위한 식품 교환
식료품 구매의 건강 및 환경 지속 가능성을 개선하기 위한 식품 교환의 무작위 시험
연구 개요
상세 설명
참가자는 온라인 피험자 간 무작위 실험을 완료합니다. 실험에는 세 번의 연구 방문이 포함됩니다.
첫 번째 연구 방문에서 참가자는 개입 없이 온라인 식료품점 쇼핑 작업을 완료합니다. 참가자에게는 $50의 예산이 주어지며 평소처럼 쇼핑을 하게 됩니다. 상점은 참가자의 선택을 기록합니다. 쇼핑 작업을 완료한 후 참가자는 온라인 설문조사를 완료하게 됩니다.
약 1주일 후 참가자는 동일한 지침에 따라 두 번째 연구 방문을 완료하게 됩니다. 그들은 4가지 조건(1) 건강만, 2) 환경만, 3) 건강과 환경이 결합된 상태, 4) 통제 중 하나에 무작위로 배정됩니다. 건강 전용 조건에서 참가자는 건강 등급이 표시된 라벨을 확인하고 선택 항목을 더 건강한 항목으로 바꾸도록 안내받을 수 있습니다. 환경 전용 조건에서 참가자는 기후 영향 등급이 표시된 라벨을 확인하고 선택 항목을 보다 지속 가능한 항목으로 바꾸도록 지시받을 수 있습니다. 건강 및 환경 조건에서 참가자는 건강 및 기후 영향 등급이 표시된 라벨을 확인하고 선택 항목을 더 건강하거나 지속 가능한 항목으로 바꾸도록 지시받을 수 있습니다. 통제 그룹에서 참가자는 라벨이나 스왑을 볼 수 없습니다. 상점은 참가자의 선택을 기록합니다. 쇼핑 작업을 완료한 후 참가자는 온라인 설문조사를 완료하게 됩니다.
세 번째 연구 방문에서 참가자는 지정된 그룹을 유지하고 두 번째 방문과 동일한 작업을 반복하도록 요청받습니다.

무기와 개입
참가자 그룹 / 팔 |
개입 / 치료 |
|---|---|
|
활성 비교기: 제어
라벨이나 스왑이 없습니다.
|
참가자는 온라인 식료품점에서 추가 라벨을 보거나 교환을 제안받을 수 없습니다.
|
|
실험적: 건강 스왑
라벨은 제품에 대한 "영양 등급"이며 교체 스왑 제안은 더 나은 영양 등급을 가진 품목에 대한 것입니다.
|
참가자들은 영국 Ofcom 영양 프로파일링 모델 점수에 따라 추정된 건강 상태를 나타내는 온라인 식료품점의 모든 제품에 붙은 "건강 등급" 라벨을 볼 수 있습니다.
건강 점수 라벨은 일부 유럽 국가에서 사용되는 라벨 시스템인 Nutri-Score 라벨을 모방하여 각 제품에 "A"(녹색)부터 "F"(빨간색)까지 색상으로 구분된 등급을 표시합니다.
"A" 및 "B" 라벨이 있는 제품은 어린이에게 판매할 수 있는 제품에 대한 영국의 기준을 충족하며 "C", "D" 및 "F" 라벨 제품은 이 기준보다 건강에 좋지 않습니다(Ofcom의 삼분위수 기준). 각 식품군 내 점수).
참가자가 장바구니에 덜 건강에 좋은 제품(예: "C", "D" 또는 "F" 건강 라벨)을 추가하려고 하면 매장에서는 동일한 카테고리의 더 건강한 제품(예: "A"가 포함된)을 자동으로 제안합니다. 또는 "B" 건강 라벨).
|
|
실험적: 기후 스왑
라벨은 제품에 대한 "기후 등급"이며, 교체 스왑 제안은 더 나은 기후 등급을 가진 품목에 대한 것입니다.
|
참가자는 기후 영향을 나타내는 모든 제품에 대한 "기후 등급"레이블을 보게됩니다.
기후 영향은 100g 당 이산화탄소 등가물 (CO2-EQ) (즉, "탄소 발자국")에서 제품을 생산하는 것과 관련된 온실 가스 배출로 계산됩니다.
라벨은 각 식품 그룹의 탄소 발자국의 5 분위에 따라 적용됩니다.
참가자가 고수익 장동 제품을 카트에 추가하려고 시도 할 때 (예 : "C" "D,"F "기후 레이블), 매장은보다 기후 친화적 인 제품 (예 :"A "또는"B "기후 레이블로 스왑을 자동으로 제공합니다.
|
|
실험적: 건강과 기후 스왑
라벨은 제품에 대한 "영양 학년"및 "기후 등급"이 될 것이며 교체 스왑 제안은 원래 선택된 제품 (영양 등급 또는 기후 등급)에서 원래 선택된 제품보다 더 나은 품목에 대한 것이며, 원래 선택된 제품보다 더 나쁘지 않습니다.
|
참가자는 온라인 식료품 점의 모든 제품에 대한 건강 및 기후 등급 레이블을 모두 볼 수 있습니다.
참가자가 "C", "D"또는 "F"라벨을 가진 제품을 카트에 대한 제품을 선택하려고 시도 할 때, 매장은 최소한 1 차원 (건강 또는 기후 친화 성)에서 원래 음식보다 개선을 제공하는 제품에 자동으로 스왑을 제공하며, 다른 치수에서는 "C,"라벨을 가진 제품을 암시하지 않는 추가 가계에 적어도 좋은 또는 더 나은 것이 었습니다.
