まとめ
Repeated self-report measures, vital for behavioral and medical research, can degrade in quality over time due to factors like assessment length and participant reactivity. Researchers must monitor these changes to ensure data accuracy.
科学分野:
- 行動科学
- 医学研究
- モバイルヘルス
背景:
- 集中的な反復自己報告測定は、動的な変数を詳細なレベルで理解するために重要です。
- モバイルヘルスアプリケーションは、介入のために正確で即時の状態と環境評価に依存しています。
- 反復的な瞬間評価は、想起バイアスを最小限に抑え、現実世界のデータをキャプチャし、個人と環境の相互作用に関する洞察を提供します。
研究 の 目的:
- 反復的な瞬間評価の完了が時間の経過とともにデータ品質をどのように変化させる可能性があるかを調査すること。
- 反復測定における不変性を誘発する可能性のある現象を特定すること。
- 研究者にデータ品質に影響を与える可能性のある潜在的な変化について警告すること。
主な方法:
- データ特性を変更する可能性のある反復的な瞬間評価の特徴を調査しました。
- 評価完了における不変性の仮定に疑問を投げかける調査の線について議論しました。
- 時間、欠損データの割合、不注意な応答、反応性という4つの現象を提示しました。
主要な成果:
- 証拠は、個人が反復評価を完了する方法において、時間の経過とともに変化が発生する可能性があることを示唆しています。
- 4つの主要な現象(時間、欠損データ、不注意な応答、反応性)が、不変性の潜在的な原因として特定されました。
- これらの変化は、収集されたデータの全体的な品質と信頼性に影響を与える可能性があります。
結論:
- 反復測定完了における不変性の仮定は、真実ではない可能性があります。
- 研究者は、さまざまな要因によりデータ品質が時間の経過とともに変化する可能性があることを認識する必要があります。
- 行動科学および医学研究におけるデータ整合性を維持するためには、これらの変化を監視し、対処することが不可欠です。

Longitudinal Research
13.1K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Statistical Analysis: Overview
14.6K
When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.
One of the most commonly used statistical quantifiers is the mean, which is the ratio between the sum of the numerical values of all results and the...

Reliability and Validity
13.7K
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.

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Strategies of Self-Presentation III: Self-Monitoring
195
Self-monitoring is a central construct in understanding individual differences in self-presentation strategies across social contexts. It refers to how individuals observe, regulate, and control their expressive behavior and self-presentation following situational cues. Self-monitoring reflects a person's sensitivity to social appropriateness and willingness to adapt behavior to fit varying interpersonal demands.High vs. Low Self-Monitoring IndividualsIndividuals high in self-monitoring are...

Self-Evaluation Maintenance Model

The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...
