Structural model of health anxiety based on intolerance of uncertainty and anxiety sensitivity with mediating the role of rumination in college students

Background and Aim: The purpose of this research was to investigate the structural model of health anxiety based on uncertainty intolerance and anxiety sensitivity with the mediation of rumination in students. Research method: This descriptive research project was conducted with structural equation modeling and with the presence of 454 people with the online sampling method among the students of Azad University, Science and Research Unit in the academic year of 1401-1400. To measure the research variables, Salkoskis et al.'s Short List of Health Anxiety (2002), Friston et al.'s Intolerance Scale (1994), Reiss et al.'s Anxiety Sensitivity Questionnaire (1986) and Nolen-Hoeksma and Maro's (1991) rumination response scale were used. Became. Data were analyzed with Pearson correlation coefficient and structural equations using SPSS and AMOS software version 24. Results: The results showed that there is a significant relationship between uncertainty intolerance, anxiety sensitivity and rumination with health anxiety (P<0.01); Also, the results showed that the direct paths of this research were significant and the indirect paths of uncertainty intolerance and anxiety sensitivity through the mediating role of rumination on health anxiety were significant. Conclusion: Based on the findings of this research, the modified model had a good fit (RMSEA=0.051 and P-value <0.05) and the final evaluated model has a good fit and is an important step towards understanding It is considered to be an effective factor on students' health anxiety
