NCT ID: NCT05483296 Completed - Healthy Clinical Trials

Effects of Afternoon and Evening Light on Teenagers' Melatonin Levels, Alertness, Sleepiness and Sleep

TeenLight
Start date: September 22, 2022
Phase: N/A
Study type: Interventional

Many teenagers are familiar with this: on school days, they have to get up early; during the day, they hardly get any light exposure; in the evening, they go to bed late - and are then tired at school the next day! Around the world, teenagers are sleep deprived, with studies suggesting that almost half (~45%) suffer from inadequate sleep. Previous investigations have shown that people's sleep-wake rhythm is related to the light conditions that they are exposed to during the day and at night. However, little is known about how different light levels in the afternoon can modulate teenagers' sleep and their bodily responses to light in the late evening. Therefore, the investigators aim to study which lighting conditions have a favourable effect on these aspects and how the potentially harmful effects of light at night can be prevented.

NCT ID: NCT01772394 Completed - Young Adult Clinical Trials

Cognitive Remediation Therapy in Anorexia Nervosa

TreCogAM
Start date: October 2012
Phase: N/A
Study type: Interventional

"Clinicians from the Maudsley (IoP, London, UK) have specifically tailored a cognitive remediation therapy (CRT) for treating Anorexia Nervosa (AN). It is an intensive manualised training cognitive therapy which addresses the difficulties in flexibility and holistic processing that have been incriminated in AN. CRT has been found to improve AN's neuropsychological functioning and short term outcome. To our knowledge, no French speaking country has tested its effectiveness. Moreover, the question whether it is efficient for both anorexic restrictive and anorexic binge-purging patients remains unanswered. The aim of the present study is to determine if CRT in AN adolescents and young adults has a favourable impact on cognitive functioning and clinical status. We will also explore whether the impact of CRT is similar in both anorexic restrictive and binge-purging subtypes. There will also be an Historical Control Group of patients, sixty, who received traditional medical interventions in a specialized inpatient unit for eating disorders (i.e., EVHAN study)."
