Stress Reduction Progress Estimator

Estimates your overall stress reduction progress (%) based on baseline stress level, current stress level, sleep quality, physical activity, mindfulness practice, and social support — weighted by evidence-based contributions to stress management outcomes.

Baseline Stress Level (1–10, before intervention)

Current Stress Level (1–10)

Sleep Quality Score (1–10, 10 = excellent)

Physical Activity (days/week, 0–7)

Mindfulness / Relaxation Practice (min/day, 0–120)

Social Support Score (1–10, 10 = very strong)

Duration of Intervention (weeks, 1–52)

#### Formula

Composite Score =   0.40 × StressReduction% + 0.20 × SleepScore% + 0.15 × ActivityScore% + 0.15 × MindfulnessScore% + 0.10 × SocialScore% Where:   StressReduction% = (Baseline − Current) / (Baseline − 1) × 100   SleepScore% = (Sleep − 1) / 9 × 100   ActivityScore% = min(Days / 5, 1) × 100   MindfulnessScore% = min(Minutes, 60) / 60 × 100   SocialScore% = (Social − 1) / 9 × 100 Duration Factor = min(0.70 + 0.30 × ln(Weeks) / ln(12), 1.0) Final Score = Composite Score × Duration Factor   (clamped 0–100)
