The Effects of Artificial Lighting on Affective and Core Symptoms of Eating Disorder — METROPOLIS  

Anorexia Nervosa Clinical Trial

Official title: The Effects of Artificial Lighting on Affective and Core Symptoms of Eating Disorder - a Pilot Study

Status Terminated

Clinical Trial Summary

The primary objective of this pilot study is to explore the effect of artificial lighting on affective symptoms, and the secondary aim is to explore the effect of artificial lighting on core symptoms of eating disorders (ED).

Several lines of evidence, albeit from hypothesis generation studies, suggest that artificial lighting may have a positive effect on well-being, mental health and affective symptoms in ED. The rationale of this study is to investigate the effects of artificial lighting on affective symptoms and cores symptoms of ED in inpatients undergoing weight restoration/treatment for ED.

Study design: Single-blind, controlled, pilot intervention study with circadian light (CL) comparing two CL regimens effects on mood symptoms.

Planned number of subjects: 16 patients with a ICD-10 diagnosis of Anorexia Nervosa, that completes exposure to at least three weeks of the two different CL regimens (L1 and L2) in any order.

Clinical Trial Description

The primary objective of this pilot study is to explore the effect of artificial lighting on affective symptoms, and the secondary aim is to explore the effect of artificial lighting on core symptoms of eating disorders (ED).

If an effect is indicated, the study will provide information on how to improve light exposure to ED patients in psychiatric treatment units. In addition, the outcomes may help identify a better system for measurement and adjustment of the specific light variables of colour temperature and light intensity.
