 DESCRIPTION (provided by applicant): Physical activity (PA) is key both to preventing childhood obesity and to reducing an individual's risk for type 2 diabetes (T2D) and certain types of cancer. While conventional PA interventions face problems of sustained motivation and adherence, active video games (AVGs) offer an innovative alternative for PA promotion due to their motivational properties. Although AVGs may allow players to achieve the recommended levels of PA, children's motivation to play AVGs often decreases quickly. To reduce this decline, we introduce an innovative motivating factor: a narrative. A narrative or storyline effectively draws on the human need for narrative closure, i.e., the need to find out how the story will end. A well-constructed narrative has a significant impact on cognition, affect, and health behavior. However, narrative elements are seldom incorporated into AVGs. An AVG with a storyline should encourage children to engage in more PA through increased motivation and extended play. Consequently, AVGs with compelling narratives should increase cognitive and affective AVG evaluation, objectively-measured PA, resulting in better body composition. We plan to explore both the novel addition of compelling narratives to AVGs and the psychological and behavioral consequences on moderate- to-vigorous PA (MVPA). We propose to first identify narrative AVG design strategies to increase PA among ethnically diverse children through 3 Experiments (Expts). Each expt looks at a critical issue regarding the narrative creation. Expt 1 examines which type of plot (continuous/episodic) would result in more MVPA. Expt 2 examines whether ethnically ambiguous characters would result in more MVPA than ethnically specific ones. Expt 3 examines which type of AVG play character (similar/ideal/fantasy) would result in more MVPA among overweight/obese children. We will then use the insight gained from Expts 1-3 to fully develop narratives for 6 AVGs and test their effect in a 3-Group Randomized Control Trial (RCT) among 210 8-12 yo children enrolled in a pediatric obesity intervention over 6 mo; the 3 groups consist of 70 children receiving only the intervention (control group), 70 children who will receive the intervention and also will play the narrative versions of the AVGs by watching corresponding narratives and playing the AVGs, and the last group of 70 will receive the intervention and will play the original versions of the AVGs without narratives. Their body composition, objectively-measured PA, measures of insulin resistance and inflammation derived from fasting glucose and insulin, C-reactive protein (CRP), and fasting lipid profiles as well as cognitive and affective AVG evaluation will be measured. This study is a first step in a series of rigorous systematic inquiries into the behavioral potentials of narratives via AVGs for combating childhood obesity and T2D. Our exploration of narrative's motivating capacities will inspire novel AVG designs and introduce a new dimension of PA facilitation with immersive and inclusive games among diverse children, which may then be translated into school- or family-based health interventions. Such inquiries would help create innovative and effective media products.

 描述（由申请人提供）：体力活动 (PA) 对于预防儿童肥胖和降低个人患 2 型糖尿病 (T2D) 和某些类型癌症的风险至关重要，而体力活动干预措施面临持续动力和坚持积极的问题。视频游戏 (AVG) 因其激励特性而为 PA 推广提供了一种创新的替代方案，尽管 AVG 可以让玩家达到建议的 PA 水平，但儿童玩 AVG 的积极性往往会迅速降低。为了应对衰退，我们引入了一个创新的激励因素：叙事或故事情节有效地利用了人类对叙事结束的需求，即需要找出故事将如何结束的需求，一个结构良好的叙事对认知有重大影响。然而，AVG 中很少包含叙事元素。带有故事情节的 AVG 应该通过增加动机和延长游戏时间来鼓励孩子参与更多的 PA，具有引人入胜的叙事的 AVG 应该增强认知和情感。 AVG 评估，客观测量 PA，从而获得更好的身体成分，我们计划探索在 AVG 中添加引人注目的叙事以及对中度至剧烈 PA (MVPA) 的心理和行为影响。 AVG 通过 3 个实验（Expts）设计策略来提高不同种族儿童的 PA。每个实验都会研究有关叙事创作的关键问题，实验 1 会检查哪种类型的情节（连续/情景）。实验 2 检查种族模糊的角色是否会比特定种族的角色产生更多的 MVPA。实验 3 检查哪种类型的 AVG 角色（相似/理想/幻想）会在超重/肥胖的儿童中产生更多的 MVPA。然后，将利用从实验 1-3 中获得的见解来充分开发 6 个 AVG 的叙述，并在 3 组随机对照试验 (RCT) 中测试其效果210 名 8-12 岁儿童参加了为期 6 个月的儿童肥胖干预；这 3 组包括 70 名仅接受干预的儿童（对照组），70 名将接受干预的儿童，并且将播放 AVG 的叙述版本观看相应的叙述并播放 AVG，最后一组 70 人将接受干预，并播放没有叙述的原始版本 AVG。他们的身体成分、客观测量的 PA、测量将测量源自空腹血糖和胰岛素、C反应蛋白 (CRP) 和空腹血脂的胰岛素抵抗和炎症以及认知和情感 AVG 评估。这项研究是一系列严格系统调查的第一步。通过 AVG 来探索叙事的行为潜力，以对抗儿童肥胖和 T2D，我们对叙事的激励能力的探索将激发新颖的 AVG 设计，并通过不同儿童的沉浸式和包容性游戏引入 PA 促进的新维度。然后可以将此类调查转化为基于学校或家庭的健康干预措施，这将有助于创造创新和有效的媒体产品。
