Interethnic Influencing Factors Regarding Buttocks Body Image in Women from Nigeria, Germany, USA and Japan.

BACKGROUND: Body image research deals a lot with awareness of the body as an entity. Studies that consider individual anatomical aspects and place them in an intercultural context are rarely present. METHODS: For this purpose, general data, body perception and judgment of body images from 2163 (48% female and 52% male) participants from Germany, Nigeria, the USA and Japan were evaluated as part of a survey. RESULTS: There were clear differences in the personal body image of the participants' own buttocks, the buttocks as a beauty ideal and the way in which dissatisfaction was dealt with in different countries. In addition to sexual well-being (importance score: 0.405 a.u.), the country of origin (0.353), media consumption (0.042) and one's own weight (0.069) were also identified as influencing factors for satisfaction with one's own buttocks. A clear evolution could be derived regarding a WHR (waist-to-hip ratio) of well below 0.7, which was consistently favored by the participants but also propagated by influencers through images (p < 0.001). In this context, participants who indicated celebrities as role models for the buttocks showed a correspondingly high level of dissatisfaction with their own buttocks (R = -0.207, p < 0.001, ρ = -0.218). CONCLUSION: Overall, a highly significant correlation was shown between the consumption frequency of Instagram, TikTok and pornography with the negative perception of women's own buttocks.

Psychometric validation of the Japanese version of the Functionality Appreciation Scale (FAS).

The Functionality Appreciation Scale (FAS; Alleva et al., 2017) is a widely adopted measure to assess appreciation for one's body and its capacity. In this study, we performed a psychometric validation of the Japanese translation of the FAS. Participants included an online sample of 750 Japanese individuals (20-70 years old), who completed the FAS and other previously validated measures of body appreciation, intuitive eating, gratitude, self-esteem, and life satisfaction. Moreover, the survey was conducted twice, 3 weeks apart, to determine test-retest reliability. Exploratory factor analyses replicated the unidimensional factor structure of the FAS, which was also verified by the confirmatory factor analysis. FAS scores had gender invariance, and demonstrated good internal consistency and test-retest reliability over the 3-week period. In addition, further analyzes indicated adequate construct, and incremental validity. These findings indicate that the Japanese version of FAS demonstrates good psychometric properties, and can be used to examine the importance of functionality appreciation for enhancing positive body image and healthy eating.

Development and Validation of a Japanese Version of the Emotion Regulation Questionnaire for Children and Adolescents.

PURPOSE: We developed a Japanese version of the Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CA) and examined its reliability and validity across three studies. PATIENTS AND METHODS: In Study 1, the Japanese version of ERQ-CA was developed and administered to 389 children aged 8-12 years. In Study 2, the questionnaire was administered to 1738 adolescents aged 12-18 years. In Study 3, utilizing a sample of 1300 children and adolescents, the test was administered twice over a period of four weeks in order to assess test-retest reliability. RESULTS: In Study 1, the Japanese version of ERQ-CA showed the same factor structure as the original version, along with good internal consistency reliability and acceptable construct validity. In Study 2, the questionnaire's factor structure, internal consistency reliability, and construct validity were again confirmed. Finally, in Study 3, measurement invariance was tested across distinct age groups (8-11, 12-15, and 16-18 years), and the questionnaire had good test-retest reliability over a period of four weeks. CONCLUSION: The Japanese version of the ERQ-CA had good reliability and validity.

Psychometric properties of the Japanese version of the Body Appreciation Scale-2 for Children (BAS-2C).

Despite the heightened interest in positive body image research in recent years, few studies have explored positive body image among children. Examining the Body Appreciation Scale-2 for Children (BAS-2C) using a different cultural sample than the original version would thus be beneficial in extending the research on this topic. This research aimed to validate the BAS-2C for use in Japan. The measures were administered to 243 children, and the participants completed the survey in their classrooms with the support of a teacher. The survey was repeated after four weeks. Confirmatory factor analysis showed that the one-factor structure was the same as that of the original version, and the BAS-2C was invariant across gender. Scores on the BAS-2C demonstrated good internal consistency and test-retest reliability over a four-week period. In addition, construct validity was accrued through the BAS-2C's correlation with body dissatisfaction (among girls), self-esteem, and life satisfaction. Results indicated that the BAS-2C shows good psychometric properties among Japanese children, and supports further research into positive body image in this group.

A Comparison of Manifestations and Impact of Reassurance Seeking among Japanese Individuals with OCD and Depression.

BACKGROUND: One of the most common interpersonal reactions to threat and anxiety is to seek reassurance from a trusted person. The Reassurance Seeking Questionnaire (ReSQ) measures several key aspects of reassurance seeking behaviour, including frequency, trust of sources, intensity, carefulness, and the emotional consequences of reassurance seeking. AIMS: The current study compares patterns and consequences of reassurance seeking in obsessive-compulsive disorder (OCD) and depression. METHOD: ReSQ scores were compared for three groups: 32 individuals with OCD, 17 individuals with depression, and 24 healthy comparison participants. RESULTS: We found that individuals with OCD tended to seek reassurance more intensely and employ self-reassurance more frequently than individuals with depression or healthy participants, and that if reassurance was not provided, they tended to feel a greater urge to seek additional reassurance. CONCLUSIONS: This study is the first to quantitatively elucidate differences in reassurance seeking between OCD and depression.
