Internalized weight bias is associated with perceived exertion and affect during exercise in a sample with higher body weight.

Objective: For individuals with overweight/obesity, internalized weight bias (IWB) is linked to low physical activity (PA). This study used a laboratory-based paradigm to test the hypothesis that IWB moderates the association between heart rate (HR) and perceived exertion and affect during PA.

Methods: Participants with overweight/obesity completed 30-min of supervised moderate-intensity treadmill walking (65%-75% of age-predicted maximal HR).

The role of avoidance-based coping in the psychosocial functioning of weight loss treatment-seeking adults.

Objective: The aim of this study was to determine the role of avoidance-based coping in the psychosocial functioning of weight loss treatment-seeking persons with obesity who report high internal disinhibition.

Methods: Participants were 162 overweight or obese adults entering a behavioural weight loss intervention programme who reported high internal disinhibition at screening. We conducted multivariate regression analyses by using mental and physical quality of life and satisfaction with relationships as dependent variables and examining the association of demographic variables, experiential avoidance (avoidance-based coping) and symptoms of depression.

Predicting treatment adherence in obstructive sleep apnea using principles of behavior change.

Study Objectives: To determine the relative predictive utility of measures of behavior-change principles on treatment adherence in individuals with obstructive sleep apnea.

Methods: Ninety-eight participants with moderate to severe obstructive sleep apnea were recruited into this prospective longitudinal study. Participants were recruited from an academic sleep disorders center after having completed in-lab polysomnography and before initiating continuous positive airway pressure (CPAP) therapy.

Examining the effect of cerebral perfusion abnormality magnitude on cognitive performance in recently abstinent chronic cocaine abusers.

Background And Purpose: Cerebral perfusion abnormalities and neuropsychological impairment are common sequelae of chronic cocaine abuse. While perfusion abnormalities have been shown to relate to cognitive deficits in this substance abuse population, the relationship between cognitive performance and the magnitude of perfusion abnormality has yet to be fully determined.

Methods: Thirty-seven abstinent cocaine abusers and 13 normal controls were administered resting 99m-Tc-HMPAO single photon emission computed tomography (SPECT) scans followed by a neuropsychological assessment battery tapping executive skills, attention, memory, and motor performance.
