まとめ
米国大学生を対象とした新しい適応的摂食尺度(AES)が開発・検証された。AESは食事の楽しみ、空腹感への対応、穏やかな栄養を測定し、良好な心理測定特性を示した。
科学分野:
- 栄養科学; 心理学; 健康行動
背景:
- 適応的摂食は、内的に調整され、楽しい摂食パターンであり、関心が高まっている。現在、米国大学生における適応的摂食を測定するための検証済み尺度はない。信頼性の高い尺度の開発は、この人口統計における健康的な摂食行動の理解と促進にとって極めて重要である。
研究 の 目的:
- 米国在住の18歳以上の大学生を対象とした適応的摂食尺度(AES)を開発し、心理測定学的に評価すること。多様な学生集団におけるAESの信頼性と妥当性を評価すること。適応的摂食の構成概念を測定するためのツールを確立すること。
主な方法:
- 37項目のAESを開発し、多様な米国大学の学生849人に実施した。尺度の因子構造を決定するために、探索的因子分析(EFA)と確認的因子分析(CFA)を使用した。AESを直観的摂食、精神的健康、食事、身体測定の尺度と相関させた。
主要な成果:
- 探索的因子分析により、穏やかな栄養(GN)、食物への渇望に囚われない(UBFC)、食事の楽しみ(EOF)、空腹感への対応(HH)の4因子に17項目が同定され、分散の63.1%を説明した。確認的因子分析は、1つのグローバル因子と4つの直交因子(GN、UBFC、EOF、HH)からなる二因子モデルを優れた適合度で確認した。GN、EOF、HHは、直観的摂食、感情的摂食、体重状態、精神的健康との信頼性と有意な関連を示した。
結論:
- 適応的摂食尺度(AES)は、大学生における適応的摂食を評価するための心理測定学的に健全な多次元尺度である。AESは、GN、EOF、HHの一般的な適応的摂食因子と特定の因子を含む。この検証済み尺度は、若年成人における適応的摂食行動とその関連因子のさらなる研究を促進することができる。

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Binge Eating Disorders
441
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

In Vitro Drug Release Testing: Overview, Development and Validation
323
In vitro dissolution and drug release tests assess how quickly and how much of a drug is released from its dosage form into an aqueous medium under standardized laboratory conditions. These tests are essential tools in pharmaceutical development and quality assurance, offering insight into the drug's performance before clinical use.During formulation development, dissolution testing identifies incomplete or inconsistent drug release issues. It also supports decisions on selecting the optimal...

pH Scale

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

Transcription Factors
82.3K
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Data Validation

Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
