The present study examined the relationship between estimation of interpersonal problems and worry. More specifically, the study examined if individuals who worry more either overestimate their interpersonal problems or both over-and underestimate their interpersonal problems. One hundred and ninety participants signed up with an identified friend and completed a series of questionnaires: the GAD-Q-IV, PSWQ, IMI-IIA, SSQ-6, FQQ, and IIP-64. Results showed that when examining overall interpersonal problems and discrepancy scores between friends, participants who worried more tended to overestimate their negative interpersonal impact on their friend. Additionally, worry was associated with overestimation of hostile-submissive, vindictive, cold, submissive, exploitable, and overly-nurturant impact on friends. Finally, participants who worried more overestimated the overall irritation in the friendship. These findings suggest that a positive linear relationship exists between higher levels of worry and overestimation of interpersonal problems.
