デジタルマイクロムーブメント・ナッジ介入が大学生のウェルビーイングと学業成績に及ぼす影響

実験的：介入群

行動：身体的回復力

この介入は、大学生の精神的健康と学業機能をサポートするために設計された、毎日の短時間の運動ベースの活動からなる、21日間のデジタル配信による身体的レジリエンスプログラムです。 このプログラムには、特別な機器や事前の身体トレーニングを必要とせずに独立して完了できる、低強度の身体運動、呼吸法、および身体ベースの調整練習が含まれています。

介入群に割り当てられた参加者は、21日間連続で1日1つの構造化された運動課題を受け取ります。 課題はTelegramチャンネルを介して配信され、参加を促すための短いデジタルリマインダーが付随します。 各課題は、時間が短く、タイミングが柔軟で、日常生活の中で実行可能なように設計されており、身体的な負荷やパフォーマンスよりも一貫性を重視しています。

この介入は自己主導型で非同期であり、対面での接触、ライブセッション、または直接の監督はありません。

State anxiety

State anxiety will be assessed using the 6-item Spielberger State-Trait Anxiety Inventory STAI-6 Six items (e.g., "I was worried these past 2 weeks.") rated from 1 (Not at all) to 4 (Very much so) will be averaged for a composite score. Higher scores indicate greater levels of anxiety.

Procrastination

Procrastination will be assessed using six items from the Irrational Procrastination Scale, such as "At the end of these past 2 weeks, I know I could have spent the time this week better." Participants will respond on a 1-5 scale (1 = Very seldom or not true of me, 5 = Very often true, or true with me), and higher average scores indicate higher levels of procrastination.

実施意図

実施意図は、「過去14日間、私は今月の目標を達成するためのステップを踏んできた」という単一項目を使用して測定されます。 1（強く反対）から5（強く同意）で採点され、スコアが高いほど実施意図が高いことを示します。

目標の進捗

目標の進捗は、「過去14日間で、今月の目標に向けた進捗が見られました。」という単一項目を用いて測定します。 スコアは1（全く同意しない）から5（強く同意する）で評価され、スコアが高いほど目標の進捗が高いことを示します。

認識された健康状態

知覚された健康状態は、一般的な健康状態に関する単一項目の自己報告尺度を用いて評価されます。 参加者は、「過去2週間のあなたの身体的健康状態をどのように評価しますか？」という質問に回答します。 回答は、1（悪い）から5（優れている）までの5段階尺度で評価されます。 高いスコアは、より良い知覚された身体的健康状態を示します。

Productivity

Productivity will be assessed using the Task Performance subscale of the Individual Work Performance Questionnaire (IWPQ), adapted to the academic context. Participants will respond to five items (e.g., "I was able to plan my work so that I finished it on time") with reference to their schoolwork. Items will be rated on a 6-point scale from 0 (seldom) to 5 (always) and then the scores will be averaged, with higher scores indicating greater productivity.

Study Burnout

Study burnout will be measured using the 9-item Study Burnout Inventory. Participants will indicate how well each item described their experiences (e.g., "I felt a lack of motivation in studying and often think of giving up") on a 6-point scale from 1 (Completely disagree) to 6 (Completely agree). Scores will be averaged, with higher scores indicating greater academic burnout.

Study Engagement

Study engagement will be measured using the 9-item Study Engagement Inventory. Participants will rate items such as "I found studying full of meaning and purpose" based on their experiences. Responses will be given on a 6-point Likert scale ranging from 1 (Completely disagree) to 6 (Completely agree) and higher scores will indicate greater levels of academic engagement.

Depression

Depression will be measured using an adapted version of the 10-item Short Depression Scale Revised (CES-D-R 10). The scale includes the sample item "I felt that everything I did was an effort." and is scored from 1 (Rarely or none of the time) to 4 (All of the time). Scores will be averaged and higher scores indicate higher risk of depression.

Life Satisfaction

Life satisfaction will be measured using an adapted version of Diener's Satisfaction With Life Scale (SWLS). The scale includes 5 items e.g. "In most ways, these past 2 weeks have been close to ideal" and is scored from 1 (Strongly disagree) to 7 (Strongly agree). Scores will be summed and higher scores indicate higher life satisfaction.

Perceived Stress

Perceived stress will be measured by an adapted version of the 4-item Perceived Stress Scale (PSS) developed by Cohen and colleagues. One sample item includes "In the last 2 weeks, how often have you felt difficulties piling up so high that you could not overcome them?" and items are scored from 0 (Never) to 4 (Very often). The composite score is calculated by summing the scores of all items; higher scores indicate higher levels of perceived stress.

Positive and Negative Affect

Positive Affect (PA) and Negative Affect (NA) will be evaluated using the Circumplex Model of Affect. Participants will rate feelings such as 'Energetic' and 'Dejected' experienced over the past two weeks, from a scale of 1 to 5 (1 = Not at all, 5 = Extremely).

Coping

Coping strategies will be assessed using the Brief COPE which is a 28-item self-report measure assessing a range of adaptive and maladaptive coping responses to stress. Participants will indicate how frequently they have engaged in various coping behaviours in response to stress over the past two weeks (e.g., "I've been taking action to try to make the situation better"). Items will be rated on a 4-point scale from 1 (I haven't been doing this at all) to 4 (I've been doing this a lot). Scores will then be averaged for each coping strategy, with higher scores indicating greater use of that coping strategy.

Emotion Regulation

Emotion regulation will be assessed using the Emotion Regulation Questionnaire (ERQ), which is a 10-item self-report measure assessing two emotion regulation strategies: cognitive reappraisal and expressive suppression. Participants will indicate the extent to which they agree with statements describing how they typically regulate their emotions (e.g., "I control my emotions by changing the way I think about the situation I'm in"). Items are rated on a 7-point scale from 1 (strongly disagree) to 7 (strongly agree). Subscale scores will be computed by averaging items corresponding to cognitive reappraisal and expressive suppression, with higher scores indicating greater use of the respective emotion regulation strategy.

Self-Control Capacity

Self-control capacity will be assessed using the Brief State Self-Control Capacity Scale (BSSCS), which is a 5-item self-report measure assessing individuals' perceived momentary self-control resources. Participants will indicate the extent to which each statement reflects their experiences over the past two weeks (e.g., "I felt like my willpower was gone"). Items are rated on a 7-point scale from 1 (not true) to 7 (very true). Items will be averaged to compute a composite score, with higher scores indicating greater state self-control capacity.
