Development and initial psychometric evaluation of the Body Image Matrix of Thinness and Muscularity - Female Bodies.

ABSTRACT: Background: Despite evidence that thinness and muscularity are part of the female body ideal, there is not yet a reliable figure rating scale measuring the body image of women which includes both of these dimensions. To overcome this shortcoming, the Body Image Matrix of Thinness and Muscularity - Female Bodies (BIMTM-FB) was developed.

Methods: The objective of this study is to analyze the psychometric properties of this measure. N?=?607 non-clinical women and N?=?32 women with eating disorders answered the BIMTM-FB as well as instruments assessing eating disorder symptoms and body image disturbance in order to test the convergent validity of the BIMTM-FB. To assess test-retest reliability, a two-week interval was determined.

Results: The results indicated that the body-fat dimension of the BIMTM-FB correlates significantly with the Contour Drawing Rating-Scale, the Drive for Leanness Scale (DLS) and the Body Appreciation Scale, while the muscularity dimension of the BIMTM-FB was significantly associated with the DLS and the Drive for Muscularity Scale, proving the convergent validity of the BIMTM-FB. High coefficients of test-retest reliability were found. Moreover, the BIMTM-FB differentiated between the clinical sample and the non-clinical controls.

Conclusions: The BIMTM-FB is a figure rating scale assessing both thinness and muscularity as part of the female body ideal. Due to its high reliability and validity, the BIMTM-FB can be recommended in research and practice.

Project description:BackgroundAlthough the link between body dissatisfaction and eating disorder (ED) pathology is well-established in general female samples, less is known about contextual body image (CBI) among female athletes. CBI refers to female athletes' body image concerns in two contexts: sport and daily life. The Contextual Body Image Questionnaire for Athletes (CBIQA) measures four dimensions of body image (Appearance, Thin-Fat Self-Evaluation, Thin-Fat Others' Evaluation, and Muscularity) in both contexts. In a sample of female collegiate athletes, this study sought to A) investigate the psychometric properties of the CBIQA, B) examine the cross-sectional relation of CBI with ED pathology and negative affect, and C) assess the degree to which CBI prospectively predicts ED pathology and negative affect.MethodUsing self-report data collected from a multi-site parent trial, we examined the psychometric properties of the CBIQA by confirmatory factor analysis. We assessed construct and criterion validity via cross-sectional bivariate correlation analyses with thin-ideal internalization, negative affect, and ED pathology. Using data from Time 1 and 6 months later (Time 2), we investigated the degree to which CBI prospectively predicted ED pathology and negative affect.ResultsResults from the CFA largely confirmed de Bruin et al.'s (2011) original factor analysis. Two CBIQA dimensions (Thin-Fat Self and Appearance) in both contexts correlated with ED pathology and negative affect. Thin-Fat Others also correlated with ED pathology in both contexts and negative affect in the sport context. The Muscularity dimension was predominantly orthogonal with other measures. CBIQA dimensions were uncorrelated with thin-ideal internalization. When controlling for BMI and Time 1 scores, daily life and sport appearance concerns predicted ED pathology, whereas perceived evaluation of thin-fat by others in the sport context predicted negative affect 6 months later.ConclusionsResults support the psychometric validity of the CBIQA and suggest that it captures variance discrete from thin-ideal internalization. The Muscularity dimension largely was not related to other outcomes. Further, specific elements of perceived self- and other-evaluation in both contexts is relevant to risk for ED pathology and negative affect. Future research could examine the impact of dual body image between sports seasons and after transitioning out of sport.Clinical trials registrationNCT01735994 .

Project description:BackgroundThis study aimed to provide a German translation of the Body Image in Pregnancy Scale (BIPS) - a measure tailored to pregnancy-specific aspects of body image while being consistent to the multifaceted theoretical framework of body image - and to test its psychometric properties and validity.MethodsThe English-language original version of the BIPS was translated into German language using a forward-backward translation rationale. Face validity of the items was tested in cognitive interviews (n = 5). An online survey was conducted among 291 pregnant women. After conducting standard item analyses, factorial validity was tested using principal-axis factor analysis (PAF). Convergent and incremental validity with measures of body dissatisfaction (FFB), depression (EPDS), anxiety (GAD-7), self-esteem (RSE), and eating disorder psychopathology (EDE-Q) was tested by bivariate correlations and multiple linear hierarchical regression analyses.ResultsThe PFA revealed a 32 item and 6-factor solution resembling the dimensions preoccupation with appearance, dissatisfaction with strength-related aspects, dissatisfaction with body parts, dissatisfaction with complexion, prioritization of appearance over function, and concerns about sexual attractiveness. Internal consistency on a subscale level was good to excellent (.79 ≤ Cronbach's α ≤ .91). Consistent with theoretical assumptions, we found significant positive correlations of BIPS-G subscales with depression, anxiety and eating disorder psychopathology and negative correlations of BIPS-G subscales with self-esteem. BIPS-G subscales substantially improved the prediction of depression, anxiety, self-esteem and eating disorder psychopathology over demographic factors and body dissatisfaction (.03 ≤ ΔR2 ≤ .15, all p-values < 0.05).ConclusionsThe German version of the BIPS appeared to be a reliable and valid measure which has the capacity to enhance future research on body image during pregnancy in German-speaking populations.

Project description:BackgroundThis paper describes the development and psychometric evaluation of a behavioral assessment instrument primarily intended for use with workgroups in any type of organization. The instrument was developed based on the Nurturing Environments framework which describes four domains important for health, well-being, and productivity; minimizing toxic social interactions, teaching and reinforcing prosocial behaviors, limiting opportunities for problem behaviors, and promoting psychological flexibility. The instrument is freely available to use and adapt under a CC-BY license and intended as a tool that is easy for any group to use and interpret to identify key behaviors to improve their psychosocial work environment.MethodsQuestionnaire data of perceived frequency of behaviors relevant to nurturance were collected from nine different organizations in Sweden. Data were analyzed using confirmatory factor analysis, Rasch analysis, and correlations to investigate relationships with relevant workplace measures.ResultsThe results indicate that the 23-item instrument is usefully divided in two factors, which can be described as risk and protective factors. Toxic social behaviors make up the risk factor, while the protective factor includes prosocial behavior, behaviors that limit problems, and psychological flexibility. Rasch analysis showed that the response categories work as intended for all items, item fit is satisfactory, and there was no significant differential item functioning across age or gender. Targeting indicates that measurement precision is skewed towards lower levels of both factors, while item thresholds are distributed over the range of participant abilities, particularly for the protective factor. A Rasch score table is available for ordinal to interval data transformation.ConclusionsThis initial analysis shows promising results, while more data is needed to investigate group-level measurement properties and validation against concrete longitudinal outcomes. We provide recommendations for how to work in practice with a group based on their assessment data, and how to optimize the measurement precision further. By using a two-dimensional assessment with ratings of both frequency and perceived importance of behaviors the instrument can help facilitate a participatory group development process. The Group Nurturance Inventory is freely available to use and adapt for both commercial and non-commercial use and could help promote transparent assessment practices in organizational and group development.
