The purpose of this study was to look at how eating disorders and the intrapersonal factors underlying ED are related to acquired capability for suicide and thwarted belongingness. More specifically, the present study wants to assess intra-personal factors that could have a correlation to the main components of IPTS. This study wants to assess five factors that could be associated with perceived burdensomeness, thwarted belongingness, and acquired capability. This includes perfectionism, body dissatisfaction, anxiety, depression, and self-esteem. I hypothesize that the higher the score of intrapersonal factors the higher the higher they predict acquired capability and thwarted belongingness. Secondly, I hypothesize that the higher the score of acquired capability and the higher the score of thwarted belongingness the higher they predict eating disorder behaviors. The results of this study found that anxiety and depression significantly predicted acquired capability for suicide. The results also indicated that depression and perfectionism significantly predicted thwarted belongingness. Lastly, the results found that thwarted belongingness significantly predicted eating disorder behavior
