Few studies have investigated community knowledge and beliefs about negative body image. Yet, low rates of recognition and help-seeking for body image concerns have been reported. Given the prevalence of body image problems and associated mental health risks in women, the current online study investigated negative body image mental health literacy in 260 women aged 18 to 64 years recruited via Prolific. The mental health literacy paradigm was employed in a 2 × 2 experimental design in which the effect of a target's domain of body image concern (appearance versus body functionality) and weight status ("normal weight" versus "overweight") was assessed on problem recognition, beliefs, and help-seeking recommendations. Overall, low symptom recognition was observed, and ratings for beliefs and help-seeking suggested low levels of stigma. However, significantly greater sympathy and lifestyle support recommendations were observed in the overweight compared to normal weight condition, and a domain × weight interaction suggested significantly fewer negative emotional reactions in the appearance overweight condition compared to appearance normal weight, and functionality overweight, conditions. The findings suggest a need for education about body image independent of weight status in women. Future research would benefit from examining diverse samples, broader functionality concerns, and stigma.
