How they work

iCBT

Core mechanism: Same cognitive and behavioral mechanisms as face-to-face CBT — restructuring distorted cognitions and modifying avoidance — delivered via digital platform

Ontology: Same as CBT — dysfunctional cognitions and avoidance maintaining distress — with the added assumption that therapeutic content can be transmitted and practiced effectively in digital form

Problem-Solving Therapy

Core mechanism: Structured problem-solving skills (define, generate, evaluate, implement) counteract hopelessness and behavioral inaction in depression

Ontology: Depression maintained by poor problem orientation (negative appraisal of problems) and deficient problem-solving skills

What each assumes — and misses

iCBT

Philosophical roots: CBT's same philosophical foundations plus pragmatist assumptions about technology as value-neutral delivery mechanism

Blind spots: Dropout higher than face-to-face; may not adequately address relational or trauma dimensions; requires digital access and literacy; variable therapist involvement across programs creates inconsistency in outcomes

Therapeutic voice: This week's module is on identifying automatic thoughts. Complete the thought record on the platform and we'll review it in our messaging check-in.

Problem-Solving Therapy

Philosophical roots: Dewey (reflective problem-solving); cognitive-behavioral tradition; D'Zurilla (social problem-solving model); pragmatism

Blind spots: Narrow skill focus may miss emotional depth; assumes problems are solvable — less suited for existential or grief concerns

Therapeutic voice: Let's list every possible solution, even the ones that seem impractical. We'll evaluate them after.

Choosing between them

iCBT and Problem-Solving Therapy both sit within the Cognitive-Behavioral tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
