Expressed Emotion (EE) can be described as a measure of the emotional temperature of the family climate and plays a role in disease course and outcome, especially in chronic illnesses. Overweight and obesity are severe problems with serious implications as far as health risks are concerned. The literature suggests having a high EE caregiver correlates with a worse treatment compliance in obese patients.

To measure level of EE, stressful events and anxiety in obese patients and their caregivers; to investigate the possible correlations between treatment compliance and EE.

We recruited 190 obese patients and 125 caregivers. Socio-demographic features were recorded. Assessment included: Level of Expressed Emotion Scale (LEE), one version for patients and one for relatives in order to evaluate 4 dimensions: Intrusiveness, Emotional Response, Attitude toward Disease, Tolerance and Expectation; the Paykel's Interview for Recent Life Events; STAI Y1 concerning state anxiety and STAI Y2 concerning trait anxiety; BMI (Body Mass Index) was measured at T0 and after 3,6 and 9 months.

We have found a correlation between gender and trait anxiety, and an inverse correlation between age and trait anxiety both in patients and caregivers. The decrease of BMI during follow-up is statistically significant and this reduction seems to be affected by tolerance and expectation perceived by patients and the emotional response on behalf of caregivers.

Levels of EE should be considered when planning treatment interventions to enhance compliance in obese patients and to support change in their life-style.
