Enhancing Motivation to Reduce Restrictive Eating: A Novel Approach.

Objective: Despite growing interest in leveraging motivational techniques to address restrictive eating, it is not yet clear how to most effectively promote motivation to reduce this behavior. Drawing from a behavioral economic framework, the present study evaluates a novel approach for increasing motivation to address disordered eating by amplifying the potential benefits of reducing dietary restriction and the consequences of maintaining disordered behaviors.

Method: A sample of 126 undergraduate students engaging in restrictive eating participated in a 7-day online experiment.

Psychometric Evaluation of the Heterosexist Harassment, Rejection, and Discrimination Scale: Identification of a Unidimensional 11-Item Scale.

Despite the Heterosexist Harassment, Rejection, and Discrimination Scale (HHRDS) being a routinely used measure of discrimination, there is no current consensus regarding its fundamental psychometric properties. This study sought to: (a) test the dimensionality of the scale using a classical test theory approach, and (b), if lacking a clear multidimensional structure, use an item response theory approach to develop a concise unidimensional measure and examine differential item and test functioning across various identity factors. In a sample of sexual minority adults ( = 1,243), evaluation of the HHRDS supported a reduced 11-item unidimensional measure.
