Brief digital sleep questionnaire powered by machine learning prediction models identifies common sleep disorders.

Introduction: We developed and validated an abbreviated Digital Sleep Questionnaire (DSQ) to identify common societal sleep disturbances including insomnia, delayed sleep phase syndrome (DSPS), insufficient sleep syndrome (ISS), and risk for obstructive sleep apnea (OSA).

Methods: The DSQ was administered to 3799 community volunteers, of which 2113 were eligible and consented to the study. Of those, 247 were interviewed by expert sleep physicians, who diagnosed ≤2 sleep disorders.

Identifying Differences in the Prevalence of Psychological Symptoms between Underweight, Normal Weight, Overweight, and Obese Children in Primary Care.

Background: The prevalence of childhood obesity continues to be a major public health problem. Nearly one-third of children in the United States can be classified as overweight or obese, which is particularly concerning given that obesity is associated with a number of physical and mental health problems. Past studies have examined childhood obesity and psychological symptoms using samples of referred children who have already been identified as overweight or obese, leaving out children who are classified as underweight or healthy weight.

The Efficacy of Low-Level Continuous Positive Airway Pressure for the Treatment of Snoring.

Study Objectives: To assess effects of low-level continuous positive airway pressure (CPAP) on snoring in habitual snorers without obstructive sleep apnea (OSA).

Methods: A multicenter prospective in-laboratory reversal crossover intervention trial was conducted between September 2013 and August 2014. Habitual snorers were included if they snored (inspiratory sound pressure level ≥ 40 dBA) for ≥ 30% all sleep breaths on a baseline sleep study (Night 1), and if significant OSA and daytime somnolence were absent.

An examination of the relation between traumatic event exposure and panic-relevant biological challenge responding among adolescents.

The current study uniquely extended research that has linked traumatic event exposure to panic-spectrum problems among adolescents. It was hypothesized that among 127 adolescents (age range: 10 to 17 years; M = 14.63, SD = 2.

Psychometric properties of the Affect Intensity and Reactivity Measure adapted for Youth (AIR-Y).

A valid and reliable instrument for measuring affect intensity does not exist for adolescents; such a measure may help to refine understanding of emotion among youths. The purpose of the current study was to evaluate the psychometric properties and clinical relevance of a measure of affect intensity adapted for youths. Two hundred five community adolescents and 179 adolescents from a residential treatment program were recruited; both samples completed self-report questionnaires, and the community-based sample participated in positive and negative mood-eliciting laboratory tasks.
