The purpose of this study was to examine the effect of an open label bright light
therapy (BLT) intervention on night eating behaviors as well as secondary outcomes of
mood and sleep quality. It was hypothesized that night eating symptoms, depression, and
sleep would significantly improve over the course of treatment. Results showed
statistically significant reductions in mean scores on measures assessing night eating
symptoms (NESS), depression (BDI), and sleep (ISI). NESS scores decreased on average
9.47 points. Mean BDI scores decreased an average of 9.60 points and mean ISI scores
decreased 5.40 points. In addition, participants reported a 47% reduction of weekly
nocturnal ingestions (t = 2.68, p = .02) from pre- to post-treatment, decreasing from an
average from 3.47 times per week before treatment to 1.83 times per week after treatment.
There was not a significant change in weight. This study was one of the first steps in
advancing the chronobiological treatment literature by testing the efficacy of bright light
therapy to improve symptoms of night eating syndrome.
