Objective We previously investigated the capacity of the original version of the Edmonton Symptom Assessment System-Revised (ESAS-r) and the Canadian Problem Checklist (CPP) to screen for clinical levels of insomnia in cancer patients. The original ESAS-r includes an item assessing drowsiness and an “other symptom” item, both of which are rated on a scale from 0 to 10, while the CPC has a sleep item, a box which is checked when this problem is present. Because none of these items showed an optim...

Background Cognitive therapy (CT) and bright light therapy (BLT) have been found to be effective to treat depressive symptoms in breast cancer patients. No study has investigated the baseline patients’ characteristics that are associated with better outcomes with CT vs. BLT in this population. This study aimed to assess, in breast cancer patients, the moderating role of eight clinical variables on the effects of CT and BLT on depressive symptoms.

Objective:The study goal was to test whether induced stress during driving could be measured at the event level through electrodermal activity responses.Background:Stress measured in simulation scenarios could thus far show an overall change in the stress state, but not be well attributed to acute stressful events. Driving simulator scenarios that induce stress measurable at the event level in realistic situations are thus warranted. As such, acute stress reactions can be measured in the context...

Abstract Objectives To examine the potential moderating effect of objectively measured sleep duration at baseline on the response to cognitive behavioral therapy for insomnia (CBT-I), administered singly or combined with medication (CBT-I + Med). Methods Based on the average PSG-derived sleep duration across two baseline nights and the type of treatment received, 159 adults with insomnia (50.3 ± 10.1 years; 61.0% women) were classified into one of four groups: participants with short sleep durat...

Objectif La somnolence diurne (SD) excessive est un symptome prevalent en population generale. Son taux de persistance (∼33 % sur 5 ans) suggere une evolution fluctuante et incite a etudier les predicteurs d’une baisse de SD : – transitoire ; – persistante sur 5 ans. Methodes La SD evaluee par l’echelle d’Epworth (ESS) et les caracteristiques socio demographiques et cliniques ont ete recueillies a l’inclusion puis chaque annee chez 2167 adultes. Une baisse persistante (BP) de SD (baisse de 4 poi...
