Abstract

Reduction in depression scores was statistically significantly larger in the bright light group compared to the dim light group.

  • 102 patients were treated with either bright light or dim light along with sertraline.
  • Bright light therapy involved exposure to 10,000 lux for 1 hour daily, while dim light was 50 lux for 30 minutes daily.
  • All depression scales showed greater improvement in the bright light group compared to the dim light group.
  • The Hamilton six-item subscale (HAM-D6) was the most sensitive measure at the study's endpoint.
