# Blinding Procedures Skill
|
|
|
|
## Purpose
|
|
Implement appropriate blinding to reduce bias in research studies.
|
|
|
|
## Types of Blinding
|
|
|
|
**Single-Blind**: Participants unaware of allocation
|
|
**Double-Blind**: Participants and researchers unaware
|
|
**Triple-Blind**: Participants, researchers, and analysts unaware
|
|
|
|
## Who to Blind
|
|
|
|
**Participants**: Reduce expectancy effects, placebo
|
|
**Interventionists**: Reduce performance bias
|
|
**Assessors**: Reduce detection bias
|
|
**Analysts**: Reduce reporting bias
|
|
|
|
## Blinding Strategies
|
|
|
|
**Medications:**
|
|
- Identical placebo (same appearance, taste)
|
|
- Over-encapsulation
|
|
- Matching packaging
|
|
|
|
**Behavioral Interventions:**
|
|
- Attention-matched control
|
|
- Active control condition
|
|
- Blind outcome assessors
|
|
|
|
**Assessments:**
|
|
- Automated/computerized measures
|
|
- Independent blinded raters
|
|
- Objective outcomes (less bias-prone)
|
|
|
|
## When Blinding Impossible
|
|
|
|
- Surgical interventions
|
|
- Exercise interventions
|
|
- Educational programs
|
|
|
|
**Mitigation:**
|
|
- Blind outcome assessors
|
|
- Use objective outcomes
|
|
- Report lack of blinding as limitation
