The Society for Light Treatment and Biological Rhythms

The Society for Light Treatment and Biological Rhythms is a not-for-profit international organization founded in 1988, dedicated to fostering research, professional development and clinical applications in the fields of light therapy and biological rhythms. The members of the SLTBR have clinical and research interests in biological rhythm disorders including: seasonal affective disorder (SAD), jet lag, shift work, sleep disorders, eating disorders, nonseasonal depression, bipolar disorder, premenstrual syndrome, and others. They study and use treatments including: light therapy, chronotherapy, melatonin, serotonergic medications, and others. The corporate members of the SLTBR have developed devices for the scientific measurement of light and for the therapeutic use of light. The SLTBR has public information sections such as "Questions and Answers about Seasonal Affective Disorder and Light Therapy" and "Questions and Answers about Melatonin".

The Center for Environmental Therapeutics

The Center for Environmental Therapeutics is a 501(c)3 nonprofit organization founded in 1994 in response to accelerating national and international interest in new environmental therapies. The Center is made up of a multidisciplinary team of eminent researchers and clinicians - experts in mental health, ophthalmology and optical physics, electrical engineering, biochemistry, physiology and gerontology - who are committed to pooling their efforts toward the development of effective environmental therapies. The innovative, free "Automated Morningness-Eveningness Questionnaire" uses a tested algorithm to derive the best schedule for light therapy determined from an individual's circadian rhythm chronotype. Clinicians can here obtain the latest assessment instrument, "The Structured Interview for the Hamilton Depression Scale with Atypical Depression Supplement" (also available as self-rating, and in a validated German version).
