Neural Relapse Prediction: AI That Knows When You'll Slip

Whistl's Neural Relapse Predictor doesn't just forecast impulses—it predicts whether you'll successfully resist them. By analysing your negotiation history, current state, and behavioural patterns, the AI forecasts bypass likelihood with 79% accuracy, enabling proactive intervention before you slip.

Understanding Relapse in Behaviour Change

Relapse isn't failure—it's a predictable part of behaviour change. Research shows:

70-80% relapse rate: Most people attempting behaviour change experience setbacks
Average attempts: 6-8 serious attempts before lasting change
High-risk situations: Specific contexts dramatically increase relapse probability
Abstinence violation effect: One slip often triggers full relapse

Whistl's Neural Relapse Predictor identifies high-risk moments before they become slips.

How Neural Relapse Prediction Works

The Relapse Predictor uses a separate neural network from the Impulse Predictor, focused specifically on negotiation outcomes:

Input Features (62 Total)

The model processes all 56 impulse prediction features plus 6 negotiation-specific inputs:

Negotiation History Features

Recent bypass attempts: Number of bypass attempts in last 24/48/72 hours
Step completion rate: Percentage of negotiation steps completed historically
Time since last successful intervention: Days since last resisted impulse
Intervention fatigue score: Frequency of recent interventions
Partner engagement: Recent accountability partner interactions
Alternative action success: Historical success rate of suggested alternatives

Relapse Probability Interpretation

The output score indicates likelihood of bypass within the next 2 hours:

Score Range	Relapse Risk	AI Response
0.00-0.30	Low	Standard negotiation flow
0.30-0.50	Moderate	Enhanced support steps
0.50-0.70	High	Aggressive intervention + partner alert
0.70-1.00	Critical	Maximum protection + crisis resources

Key Relapse Predictors

Research identified the strongest predictors of negotiation failure:

1. Intervention Fatigue (Weight: 14.2%)

Frequent interventions reduce effectiveness over time:

3+ interventions in 24 hours = 40% bypass rate
5+ interventions in 24 hours = 67% bypass rate
AI response: Extend cooldown periods, reduce intervention frequency

2. Recent Bypass History (Weight: 12.8%)

Recent successful bypasses predict future bypasses:

1 bypass in last 24 hours = 2.3x relapse risk
2+ bypasses in last 24 hours = 4.1x relapse risk
AI response: Escalate to partner notification immediately

3. Step Completion Rate (Weight: 11.5%)

Users who skip early steps are likely to bypass:

<50% step completion = 71% bypass rate
50-80% step completion = 34% bypass rate
>80% step completion = 12% bypass rate
AI response: Enforce mandatory early steps

4. Time of Day (Weight: 9.3%)

Late night negotiations have higher failure rates:

10pm-2am: 58% bypass rate
2pm-6pm: 23% bypass rate
AI response: Extend cooldown timers at night

5. Partner Engagement (Weight: 8.7%)

Active partner support reduces relapse:

Partner responded in last 24 hours: 31% bypass rate
No partner response in 7+ days: 64% bypass rate
AI response: Proactive partner notification

Adaptive Intervention Strategies

Based on relapse probability, the AI modifies its approach:

Low Relapse Risk (0.00-0.30)

Standard 8-step negotiation with normal timing:

All steps available in personalised order
Standard cooldown periods
Optional partner notification

Moderate Relapse Risk (0.30-0.50)

Enhanced support with additional scaffolding:

Mandatory breathing step (cannot skip)
Extended visualization duration
Multiple alternative suggestions
Partner notification sent

High Relapse Risk (0.50-0.70)

Aggressive intervention with maximum support:

Extended breathing (3 minutes mandatory)
Partner alert with urgency flag
Crisis resources displayed
Maximum cooldown (30 minutes)
Direct AI coach engagement

Critical Relapse Risk (0.70-1.00)

Crisis intervention mode:

Full negotiation sequence enforced
Immediate partner phone call option
Crisis hotline quick-dial displayed
SpendingShield locked to RED
Post-intervention follow-up scheduled

Real-World Relapse Prediction Examples

Example 1: Marcus's Escalating Risk

Scenario: Marcus has attempted 3 bypasses today

Input Signals:

Bypass attempts (24h): 3
Step completion rate: 42%
Time: 11:30pm
Partner engagement: None in 5 days
Intervention fatigue: High (7 interventions today)
HRV: 28% below baseline

Relapse Prediction: 0.78 (Critical)

AI Response: Crisis mode activated. Partner called. Crisis resources displayed. Full negotiation enforced.

Example 2: Sarah's Moderate Risk

Scenario: Sarah is stressed but engaged with support

Input Signals:

Bypass attempts (24h): 0
Step completion rate: 78%
Time: 3:00pm
Partner engagement: Check-in yesterday
Intervention fatigue: Low (1 intervention today)
Calendar stress: High (presentation tomorrow)

Relapse Prediction: 0.41 (Moderate)

AI Response: Enhanced support. Mandatory breathing. Partner notified. Extended visualization.

Learning from Outcomes

The Relapse Predictor continuously improves through outcome tracking:

Outcome Recording

After each intervention, the AI records:

Was the bypass attempt successful or blocked?
How many steps were completed?
Did the user engage with alternatives?
Did the partner respond?
What was the spending outcome (if any)?
User-rated intervention helpfulness

Weight Updates

# Outcome-based learning
if prediction == 0.75 and user_bypassed:
    # Prediction was correct - reinforce weights
    reinforce_predictive_features()
elif prediction == 0.75 and user_did_not_bypass:
    # Prediction was wrong - adjust weights
    reduce_weight_on_false_positive_features()
    identify_protective_factors()

Personal Calibration

After 30 days, the model is calibrated to YOUR patterns:

Your specific high-risk contexts
Your response to different intervention types
Your partner's effectiveness
Your alternative action success rates

Relapse Prevention Strategies

Beyond prediction, Whistl actively prevents relapse:

Pre-Emptive Interventions

When relapse risk is elevated but no bypass is attempted:

Proactive check-in messages
Reminder of recent successes
Suggestion to contact partner
Goal progress review

Slip Recovery Protocol

If a bypass occurs, the AI activates recovery mode:

Non-judgmental acknowledgment
Immediate spending limit reset
Partner notification (if configured)
Crisis resource display
Re-engagement invitation

Abstinence Violation Prevention

To prevent one slip becoming full relapse:

Reframing messages ("This is a slip, not failure")
Progress preservation ("You still have 23 clean days this month")
Learning opportunity ("What triggered this? Let's plan for next time")
Immediate re-engagement ("Ready to get back on track?")
