Engineering Digital CBT: Algorithmic Personalization and Engagement in Mental Health SaMD

How clinical psychologists and software engineers collaborate to translate Cognitive Behavioral Therapy (CBT) protocols into effective digital software.

Translating In-Person Therapy into Digital Micro-Interventions

Digital CBT cannot simply be digitizing PDF workbooks. Effective mobile therapy requires engaging micro-interventions: interactive mood tracking, cognitive reframing exercises, and just-in-time adaptive interventions (JITAI) triggered by smartphone sensor telemetry.

Algorithmic Adaptation and Behavioral Reinforcement

Using contextual bandit algorithms and reinforcement learning to personalize the timing, tone, and difficulty of therapeutic content based on the patient's current stress levels and past engagement patterns.

Clinical Trial Methodologies for Digital Therapeutics

Designing randomized controlled trials (RCTs) with digital sham placebos to isolate the active therapeutic effect of software interventions and prove clinical efficacy.
