Variable

Measurement Tool

Scoring Criteria

Dependent Variable – Long-term Adherence (A)

  

A1: Rehabilitation Program Completion Rate

Percentage of prescribed rehabilitation sessions completed

100% completion rate indicates full adherence.

A2: Self-reported Adherence Score

Self-Report Adherence Scale (SRAS)63

5-point Likert scale (1 = never, 5 = always) for adherence to prescribed activities

A3: Completion of Specific Rehabilitation Activities

The Stroke Rehabilitation Assessment of Movement (STREAM)64

Percentage of completed rehabilitation activities during follow-up visits (T1, T2, T3)

A4: Number of Interruptions and Re-engagement

Count of interruptions and re-engagement

The number of interruptions and re-engagements during the rehabilitation program

Independent Variables: Physiological Monitoring (B)

  

B1: Heart Rate

Polar heart rate monitor

Measured in beats per minute (bpm)

B2: Blood Pressure

Automatic blood pressure cuff (Omron)

Measured at each follow-up visit

B3: Physical Activity

Step count (e.g., pedometer, smartphone app)

Measured in steps per day (e.g., 3000–5000 steps per day indicates moderate activity level)

B4: BMI

Formula: BMI = weight (kg) / height (m)^2

BMI calculation at each follow-up visit

Independent Variables: Psychological Monitoring (C)

  

C1: Depression Scores

PHQ-9 (Patient Health Questionnaire-9)65

The PHQ-9 consists of 9 items, each rated from 0 (not at all) to 3 (nearly every day). The total score ranges from 0 to 27

C2: Anxiety Scores

GAD-7 (Generalized Anxiety Disorder-7)66

The GAD-7 contains 7 items, each rated from 0 (not at all) to 3 (nearly every day). The total score ranges from 0 to 21

C3: Positive Mood

PANAS (Positive and Negative Affect Schedule)67

The PANAS consists of 20 items, rated from 1 (very slightly or not at all) to 5 (extremely). Measures positive affect (PA) and negative affect (NA)

C4: Stress Levels

PSS (Cohen’s Perceived Stress Scale)68

The PSS has multiple versions, with the most common being the 10-item version (PSS-10). Each item is rated on a scale from 0 (never) to 4 (very often).

Independent Variables: Personalized Feedback Interventions (D)

  

D1: Frequency of Feedback

Count of feedback sessions

The number of feedback sessions provided over the study period (e.g., weekly, bi-weekly)

D2: Feedback Validity Scores

Patient Satisfaction Questionnaire (PSQ)69

5-point scale (1 = not useful, 5 = very useful) to rate the usefulness of feedback

D3: Feedback Relevance Scores

Patient ratings

Measures how relevant feedback was to the patient’s rehabilitation goals using a 5-point scale

D4: Patient Feedback Response Score

Engagement with feedback

1–5 scale quantifying the frequency of feedback acknowledgment or incorporation into rehabilitation plans
