The New Somatomorphic Matrix-Male (NSM-M; Talbot et al., 2019) is a pictorial bi-dimensional figure rating scale for men. The scale presents a matrix of 34 computer-rendered frontal-view male bodies, each with a unique graded combination of body fat and muscularity. It is used to assess how men perceive their body (actual body) and identify the body that they would like to have (ideal body). The difference (discrepancy) between a man’s selected actual and ideal bodies can be used as an index of body dissatisfaction. The NSM-M can be administered online or in-person to men and is free to use. This chapter first discusses the development of the NSM-M and then provides evidence of its psychometrics. Test-retest reliability, convergent validity, concurrent validity, and discriminant validity support the use of the NSM-M. The entire matrix is included within the chapter. Logistics of use, such as permissions, copyright, and contact information, are provided for readers.

The 10-item Beliefs About Penis Size Scale (BAPS; Veale et al., 2014) measures boys’ and men’s beliefs about masculinity and shame related to their penis size. Penis size is a primary appearance concern of men, and these concerns may result in penile dysmorphic disorder, which is a form of body dysmorphic disorder specifically focused on being preoccupied with and distressed by one’s penis size. The BAPS can be administered online or in-person to adolescents and adults and is free to use. This chapter discusses the development of the BAPS and provides evidence of its psychometrics. Findings suggest that the BAPS is a unidimensional measure. Internal consistency reliability as well as convergent, concurrent, and discriminant validity support the use of the BAPS with boys and men. This chapter provides the BAPS items in their entirety, instructions for administering the BAPS to participants, item response scale, and scoring procedure. Logistics of use, such as permissions, copyright, and contact information, are provided for readers.

The Photographic Figure Rating Scale (PFRS; Swami et al., 2008) is a figural rating scale developed to assess body dissatisfaction (actual-ideal body size discrepancy) and consists of 10 photographic images of real women varying in body mass index from emaciated to “obese”. The PFRS can be administered online or in-person to women and is free to use for non-commercial purposes. This chapter discusses the development of the original PFRS, before providing evidence of its psychometric properties. Specifically, scores on the PFRS have been found to have adequate test-retest reliability and good patterns of convergent and criterion-related validity. Next, this chapter provides the PFRS images, as well as full instructions for administration to participants, the suggested questions, and the scoring procedure. Known translations are described and logistics of use are provided for readers.

The Breast Size Rating Scale (BSRS; Swami et al., 2015) is a figural rating scale developed to assess breast size dissatisfaction (actual-ideal breast size discrepancy), theorised to be a facet of negative body image. The BSRS consists of 14 computer-generated images of women varying in breast size alone. The BSRS can be administered online or in-person to women and is free to use for non-commercial purposes. This chapter discusses the development of the BSRS, before providing evidence of its psychometric properties. Specifically, scores on the BSRS have adequate test-retest reliability and good patterns of convergent, criterion-related, and incremental validity. Next, this chapter provides the BSRS in full and instructions for administering the BSRS to participants, the suggested questions, and the scoring procedure. Known translations are described and logistics of use are provided for readers.

The 9-item Body Image Life Disengagement Questionnaire (BILD-Q; Atkinson & Diedrichs, 2021) assesses behavioral avoidance of important life activities due to body image and appearance concerns. Encompassing life domains beyond physical and mental health (e.g., participation in education and sport, socializing, seeking healthcare, self-assertion), the BILD-Q contributes to understanding the broader consequences of negative body image on individual development and future contribution to society. The BILD-Q can be administered online or in-person to adolescents and adults and is free to use. Women and men complete the same 28 items. This chapter first discusses the development of the BILD-Q and then provides evidence of its psychometrics. Exploratory and confirmatory factor analyses have shown the BILD-Q to have a unidimensional factor structure. Its gender invariance has been upheld among early adolescents. Internal consistency reliability, test-retest reliability, convergent validity, and incremental validity support the use of the BILD-Q. This chapter provides the BILD-Q items in their entirety, instructions for administration and scoring, and the item response scale. Links to available translations are included. Logistics of use, such as permissions, copyright, and citation information, are also provided for readers.

The 15-item Body Image Self-Consciousness (BISC) Scale (Wiederman, 2000) is a widely used contemporary measure of the extent individuals are self-conscious of their own bodily appearance during physical intimacy with a partner. The BISC Scale can be administered online or in-person to adolescents and adults with and without partnered sexual experience, and to those with male or female sexual partners. The BISC Scale is free to use in any setting. First, this chapter discusses the development of the BISC Scale and provides evidence of its psychometrics properties. Specifically, the BISC Scale has been found to have a single-factor structure within exploratory and confirmatory factor analyses and is invariant across male and female genders.

This chapter provides the BIMTM in its entirety, as well as its instructions for administration and scoring. Logistics of use, such as permissions, copyright, and citation information, are also provided for readers.

The 25-item Body Parts Satisfaction Scale for Men (BPSS-M; McFarland & Petrie, 2012) is a commonly used measure of male body satisfaction, which focuses on the degree a male-identified adolescent or adult is satisfied with their appearance, particularly with respect to leanness (or low body fat) and muscularity. The BPSS measures male body satisfaction across three factors: upper body, legs, and face. The BPSS-M can be administered online or in-person to male identifying adolescents and adults and is free to use. This chapter first discusses the development of the BPSS-M and then provides evidence of its psychometrics. More specifically, the BPSS-M’s 3-factor structure is upheld within exploratory and confirmatory factor analyses. Internal consistency reliability, test-retest reliability, convergent validity, concurrent validity, and incremental validity support the use of the BPSS-M. Next, this chapter provides the BPSS-M items in their entirety, instructions for administration and scoring, and the item response scale. Logistics of use, such as permissions, copyright, and contact information, are available for readers.

The 32-item Anti-Fat Microaggression Experiences Questionnaire (AFMEQ; Webb et al., 2019) assesses contemporary forms of weight bias that individuals living in larger bodies routinely confront. The AFMEQ can be administered online or in person to older adolescents and adults and has not been validated for use in younger populations. It is free to use in research settings. This chapter first discusses the development of the AFMEQ and then provides evidence of its psychometrics. More specifically, the AFMEQ has been found to have a four-factor structure within exploratory factor analyses (Micro-Assault, Micro-Insult, Micro-Invalidation, and Media-Influenced Microaggression), aligning with the original microaggression framework but adding a novel recognition of the influence of media in promulgating oppressive stereotypes denigrating higher-weight individuals. Internal consistency reliability, test-retest reliability, convergent validity, discriminant validity, and incremental validity support the use of the AFMEQ. Next, this chapter provides the AFMEQ items in their entirety, instructions for administering the AFMEQ to participants, the item response scale, and the scoring procedure. Abbreviated forms are not offered, and no known translations are currently available. Logistics of use, such as permissions, copyright, and contact information, are provided for readers.

The 12-item Yale-Brown Obsessive-Compulsive Scale Modified for Body Dysmorphic Disorder (BDD-YBOCS; Phillips et al., 1997) is a widely used, semi-structured, clinician or rater-administered measure of a person’s current severity of body dysmorphic disorder (BDD). To emphasize, the BDD-YBOCS is a severity measure and not a screening or diagnostic measure of BDD, and it should be used only in individuals who have already been diagnosed with BDD. The BDD-YBOCS has been the primary outcome measure in most treatment studies of BDD and is also used in clinical settings. It can be administered online or in-person to children, adolescents, and adults and is free to use, although a fee may be charged for more than a certain number of free uses. This chapter first discusses the development of the BDD-YBOCS and then provides evidence of its psychometrics. It has three factors: a core symptoms factor (BDD diagnostic criteria), a resistance-control factor (for thoughts/preoccupation), and a repetitive behaviors factor. Internal consistency, interrater reliability, test-retest reliability, convergent validity, and discriminant validity support the use of the BDD-YBOCS. It is sensitive to change as a result of clinical intervention. This chapter directs readers for how to obtain the full list of items. Logistics of use, such as permissions, copyright, and contact information, are provided for readers.

The Curvy Ideals Internalization Scale (CII; Walker et al., 2022) is an 11-item self-report measure developed to assess internalization of a thick or curvy body type. The CII can be administered online or in-person and is free to use for research purposes, and has been validated among White, Black, and Black/White Biracial women. The chapter first discusses the development of the CII and then provides evidence of its psychometric properties. More specifically, the CII has been identified to have a three-factor structure, with exploratory and confirmatory factor analyses. Internal consistency reliability, convergent validity, and discriminant validity support the CII’s use. The chapter provides the CII items in their entirety, instructions for administering and scoring the measure, and the item response scale. Logistics of use (e.g., copyright, permissions, and contact information) are provided for readers.

The Body Mass Index-Based Figure Rating Scale for Chinese Adolescents (C-BMI-FRS; Yu et al., 2022) provides a brief way to assess the body dissatisfaction of Chinese adolescents via calculating the discrepancy between their chosen actual and ideal body silhouettes. Height, weight, sex, and age data was calculated from a large sample of Chinese adolescents and a professional artist drew four equal height silhouettes for each sex (girls, boys) based on these data. The four silhouettes, which represented BMI values at the 20th, 40th, 60th, and 80th percentiles, were placed above a horizontal bar with 25 grids. Respondents choose the number (1-25) that represents the figure that they actually have and the figure they ideally would like to have. Their chosen ideal figure is then subtracted from their chosen actual figure. The figures and logistics of use, such as permissions, copyright, and contact information, are provided for readers.

The 20-item Fit Ideal Internalization Test (FIIT; Uhlmann et al., 2020) assesses girls’ and women’s thoughts, feelings, and behaviors that represent manifestations of three interrelated fit ideal internalization domains: personal idealization of the fit ideal, overvaluing of the fit ideal, and striving for a lean and toned female body shape. The FIIT operationalizes the fit ideal as a distinct set of ideals, values, and desires that differ from those associated with either the thin body ideal or the muscular body ideal. The FIIT can be administered online or in-person to female-identifying adolescent and adults and is free to use. This chapter first discusses the development of the FIIT and then provides evidence of its psychometrics. More specifically, the FIIT has a 3-factor structure within exploratory and confirmatory factor analyses: Fit Idealization (8 items), Fit Overvaluation (8 items), and Fit Behavioral Drive (4 items). Evidence has been found for a higher-order factor. Internal consistency reliability, test-retest reliability, convergent validity, discriminant validity, and incremental validity support the use of the FIIT. Next, this chapter provides the FIIT items in their entirety, instructions for administration and scoring, and the item response scale. Logistics of use, such as permissions, copyright, and contact information, are available for readers.

The Body Image Acceptance and Action Questionnaire (BIAAQ; Sandoz et al., 2013) is a 12-item measure of body image flexibility. Body image flexibility involves full awareness and openness to the experience of embodiment (e.g., body image thoughts, feelings, perceptions, sensations, etc.) in any one moment in such a way as to allow for engagement in valued action. The BIAAQ can be administered to adults or adolescents in person or online. This chapter discusses the development of the BIAAQ and provides evidence for its reliability and validity. More specifically, the majority of studies evaluating the psychometric properties of the BIAAQ have found the instrument to be composed of a single-factor. Internal consistency, test-retest reliability, split-half reliability, convergent validity, and incremental validity support the use of the BIAAQ. This chapter provides the BIAAQ items in their entirety, instructions for administering the scale to participants and the scoring procedure. Abbreviated and translated versions are also summarized. Logistics of use, such as permissions, copyright, and contact information, are provided for readers.

The 15-item Muscularity-Oriented Eating Test (MOET; Murray et al., 2019) assesses attitudes and behaviors associated with the pursuit of muscularity, such as the rigid monitoring of dietary intake, rigid adherence to dietary rules, regulation of protein intake, propensity for eating more or less to influence muscularity, and the overevaluation of muscularity-oriented eating. The MOET can be administered online or in-person to adolescents and adults and is free to use. This chapter first discusses the development of the MOET and then provides evidence of its psychometrics. Findings from exploratory and confirmatory factor analysis consistently suggest that the MOET is a unidimensional measure in a broad array of demographic and cultural settings. Internal consistency reliability, test-retest reliability, convergent validity, discriminant validity, and incremental validity support the use of the MOET. Next, this chapter provides the MOET items in their entirety, instructions for administering the MOET to participants, item response scale, and scoring procedure. Links to known translations are provided. Logistics of use, such as permissions, copyright, and contact information, are provided for readers.

The 37-item Multidimensional Assessment of Interoceptive Awareness, Version 2 (MAIA-2; Mehling et al., 2018) assesses body awareness; that is, the ability to notice sensory signals originating from inside the body that provide information about its physiological states, processes, and actions. The MAIA-2 can be administered online or in-person to adults, including to clinical populations such as people with chronic pain, eating disorders, and depression (the 32-item MAIA-Youth should be used for children and adolescents). The MAIA-2 is free to use, and no written permission is required to use it for scholarly and non-commercial purposes. This chapter first describes the development of the MAIA-2, and then provides evidence of its psychometric properties. More specifically, the MAIA-2 was initially purported to have an 8-factor structure within exploratory and confirmatory factor analyses. However, fit indices for the 8-factor model have been less-than-ideal in numerous studies, and more recently authors have found acceptable model fits when examining bi-factor models and a higher-order models, suggesting that the MAIA-2 items and scales, respectively, also load onto a general factor, with the exception of the Not-Distracting and Not-Worrying items, which may correlate with this factor. MAIA-2 scores are scalar invariant across men and women, and composite reliability, test-retest reliability, convergent validity, discriminant validity, and incremental validity largely support the use of the MAIA-2. Next, this chapter provides directions to the MAIA-2 items and instructions for administration, and the item response scale and scoring procedure. An overview of available translations and abbreviations is provided. Finally, permissions, copyright, and contact information are provided for readers.
