A guide to exploratory structural equation modeling (ESEM) and bifactor-ESEM in body image research.

Traditionally, assessments of factor validity of body image instruments have relied on exploratory or confirmatory factor analysis. However, the emergence of exploratory structural equation modeling (ESEM), a resurgence of interest in bifactor models, and the ability to combine both models (bifactor-ESEM) is beginning to shape the future of body image research. For these analytic approaches to truly advance body image research, scholars will need to have a deep understanding of their use and application.

Measurement invariance and differential item functioning of the functionality appreciation scale (FAS) in Colombia and Spain.

The Functionality Appreciation Scale (FAS) is increasingly used in diverse national and linguistic contexts. However, limited work has assessed the extent to which the instrument demonstrates measurement invariance and differential item functioning (DIF) across nations and respondent characteristics. Here, we examined measurement invariance and DIF of the FAS using archival data from adults in Colombia (Mebarak et al.

A person-centred investigation of the associations between actual and perceived physical fitness among youth with intellectual disabilities.

The main objective of this person-centred study was to identify profiles of actual and perceived physical fitness among a sample of youth with intellectual disabilities (ID). Participants were 377 youth (60.4% boys) with mild (49.

The Experience of Embodiment Scale: An examination of its psychometric properties in women from the Republic of Cyprus.

The Experience of Embodiment Scale (EES) is a recently developed instrument that assesses experiences of living in the body. Here, we prepared a novel Greek translation of the EES and examined its psychometric properties. We initially prepared a Greek translation of the EES using a 5-step procedure recommended for test adaptation studies.

Psychosocial Difficulties Profiles Among Youth with Intellectual Disabilities.

This study sought to identify the various configurations, or profiles, of internalizing and externalizing behaviors found among a sample of youth with intellectual disabilities (ID). These behaviors were assessed twice over one year, using self, parental, and teacher reports. Six variables were hypothesized to predict profile membership: Parent-child relationship (i.
