概括

这项研究开发了一个新的尺度来估计青少年的超加工食品消费,使用物品反应理论. 较高的消费水平与增加的总能量摄入量和减少天然食物摄入量相关.

科学领域:

心理测量心理测量心理测量
营养流行病学营养流行病学
青少年健康青少年健康

背景情况:

超加工食品 (UPF) 与不良健康结果有关.
准确评估UPF消费对于公共卫生干预至关重要.
测量UPF摄入量的现有方法在特定人群中可能存在局限性.

研究的目的:

开发和验证用于估计青少年超加工食品消费的心理测量尺度.
为了利用物品响应理论 (IRT) 进行规模开发.
评估UPF消费与其他饮食模式之间的关系.

主要方法:

一项心理测量研究使用了来自巴西出生队伍的2515名青少年 (18-19岁) 的数据.
使用了经过验证的食物频率问卷.
探索性因子分析和Samejima的分级响应模型 (IRT) 用于规模构建和验证.
统计测试 (克鲁斯卡尔-瓦利斯,威尔科克森) 分析了潜在的特征水平.

主要成果:

开发的尺度有效地覆盖了整个潜在特征连续体,用于估计UPF消耗.
增加的UPF消耗与潜在特征成正比 (P < 0.05).
较高的UPF消费水平与自然食品摄入量减少和总能量摄入量增加有关 (P < 0.05).

结论:

拟议的尺度表现出一致性,是评估超加工食品消费的可行简要工具.
这种工具可以帮助识别高UPF摄入量的青少年.
进一步的研究可以探索其在不同人群中的应用以及监测饮食变化.

Response Surface Methodology

Response Surface Methodology

Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:

The Availability Heuristic

The Availability Heuristic

A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Confirmation Biases

Confirmation Biases

The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?
