Checklist
Do not count a digital-detox plan as behavior change
A plan can increase confidence without moving the usage graph.
When it fits
- You wrote rules for smartphone use and feel the intervention is already working.
When to avoid it
- The trial population was university students near exams; other groups may respond differently.
Checklist
- Write the intended rule.
- Measure objective usage when possible.
- Compare post-plan use with baseline.
- If behavior does not change, alter the environment rather than writing a more inspirational plan.
Why it matters
A 2025 preregistered RCT with 787 participants found a planning intervention increased self-efficacy but did not significantly reduce total smartphone usage in the post-intervention period. Keep planning, but verify actual behavior. If use does not change, add environmental friction, blocking, relocation or a different intervention.
An example
A rule such as 'less Instagram after dinner' is not evidence until actual evening use changes.
Check your result
Success is based on observed behavior or outcome, not intention or confidence alone.
Keep this limit in mind
- The trial population was university students near exams; other groups may respond differently.
