Transparent Reporting of Evaluations with Nonrandomized Designs (TREND)

Evidence-based public health 趋势2外汇交易系统下载 decisions are based on evaluations of intervention studies with randomized and nonrandomized designs. Transparent reporting is crucial for assessing the validity and efficacy of these intervention studies, and, it facilitates synthesis of the findings 趋势2外汇交易系统下载 for evidence-based recommendations. Therefore, the mission of the Transparent Reporting of Evaluations with Nonrandomized Designs (TREND) group is to improve the reporting standards of nonrandomized evaluations of 趋势2外汇交易系统下载 behavioral and public health interventions.

The 趋势2外汇交易系统下载 TREND statement Cdc-pdf [338 KB] 1 has a 22-item checklist Cdc-pdf [368 KB] specifically developed to guide standardized reporting of nonrandomized controlled trials. The TREND statement complements the widely adopted CONsolidated Standards Of 趋势2外汇交易系统下载 Reporting Trials (CONSORT) statement developed for randomized controlled trials. A collective effort in promoting transparent reporting is valuable to improve research synthesis and advance evidence-based recommendations for best practices and policies. We encourage all 趋势2外汇交易系统下载 researchers, funding agencies, journal editors, and reviewers 趋势2外汇交易系统下载 to use the TREND Statement as a guide when designing evaluation studies, reporting evaluation results, and reviewing manuscripts for scientific publication.

Because the TREND statement is intended to be an evolving document, we welcome your comments and feedback to help revise the statement periodically

The TREND statement was 趋势2外汇交易系统下载 first published in a special issue of 趋势2外汇交易系统下载 the American Journal of Public Health in March 2004. The issue was devoted to evaluation research. This special issue contains a number of papers related to the use of nonrandomized or quasi-experimental designs in the evaluation of interventions.

今年,受主客观条件制约,大部分业务和产品,面临疲软的消费市场,不能投入太多的资源。要实现生存和发展,必须找到新的视角和增长方式:即在消费变化趋势中挖掘潜在的机会点。

事实上,大环境变动对人们消费心态的影响是非常巨大且复杂的,不能直接用【降级】粗暴概括。

1)关于购物行为

2)关于大众情绪

3)关于品牌偏好

4)关于生活方式

一、关于购物行为

1. 灵活腾挪的方案

用户价值=新体验-旧体验-替换成本

然后,在外部强大影响力(疫情)的驱动下,很多消费习惯随之变动,尤其任务型购买中,针对同一需求,人们往往更灵活、更主动去采取新的购买方案——意味着替换成本降低,新体验获得更大的价值空间

此前有媒体统计, 一辆公路自行车售价从5000元到10万元不等, 5000元以上的车型则是主流消费区间,其中5000-8000元档最为畅销,10000-15000元价位档的车型销量增速也很快。

用户把去健身房年卡的费用,因疫情闭店影响,转移到投资自行车的骑行锻炼上。

  • 露营取代跨市旅行;
  • 房车替代酒店和短租;
  • 上门清扫服务,正在被洗地机、专业扫地机器人等抢占市场;
  • 家用蒸发、高端吹风替代定期美发spa;
  • 更简单操作的美甲片替代美甲师和美甲店;
  • 按摩泡脚桶、按摩椅、筋膜枪替代按摩服务等;
  • ……

2. 跨品类平替

  • 比如泊莱雅发明的早C晚A,让双抗精华成为一种护肤新理念,而不是大牌精华的简单平替。
  • 小家电领域对这一套也玩得很熟了,简单地把产品【迷你化】+【细分化】,一个新物种平替就诞生了——迷你冰箱、内衣洗衣机、二人食双内胆电饭煲等。
  • 最近一款产品,争议比较大,叫做【人参水】——昂贵人参的平替,不是便宜人参,而是一个跨品类的养生饮料。。

2022下半年,关于消费的5个小趋势

跨品类平替的价值在于,从某种程度上,抵消了消费者在内心【选择便宜货】的不爽,而是【发掘新大陆】的开心和优越感。对年轻消费者来说,比传统降价平替,更具备吸引力。

在营销层面,这类产品初期可以绕开既有品类定位+广告轰炸心智的打法,以【流行趋势种草】+【口碑传播】方式快速占领市场(这类产品价格相对更低,用户为此付出的尝鲜成本不高,更容易接受),并在从0到1的市场教育过程中获得认知红利,建立自己的品类壁垒。

二、关于大众情绪

同一时空,集体叙事

  • 同一时间:肯德基的疯狂星期四和饿了么的一分钟免单,火爆全网且热情不减,大家享受共同掐表、定闹钟、相互提醒,到点疯狂薅羊毛。
  • 同一网络空间:各类直播间让人们隔着屏幕,有了新的聚集地,无论在刘畊宏直播间一起健身,还是在东方甄选的直播间一起学习。

在构思营销活动的时候,不妨从【一起做一件事】的角度考虑,打造让【全民任性】放大热情和滚雪球效应。
