The construct of emotional intelligence (trait EI) refers to the individual differences in the perception, processing, regulation and utilization of emotional information. Several studies have found that trait EI was a significant moderator of response to stress. The present study explores whether trait EI also influences the response to internal stress: the health-related anxiety. More specifically, the aim of this study was to test the influence of Trait EI dimensions: Self-control, Emotional sensitivity and Adaptability, on health-related beliefs: Magic thinking, Tragic consequences of disease, Liability to disease and Vulnerability to disease. A sample of 119 individuals from the general population, aged 18–72years participated in this research (65% women, mean age 37.55years). They answered a questionnaire on the web consists of two validated scales: TEIQue (Petrides & Furnham, 2003) and the Health-related beliefs Questionnaire (Pelletier, Gosselin, Langlois & Ladouceur, in 2000), as well as socio-demographic variables. Descriptive analysis and t-tests were first performed, and correlations and variance and, finally, linear regression analysis. All these tests were performed using the statistical software SPSS® Statistics® IBM. The results indicate that high trait EI individuals exhibit less health-related anxiety (β=−0.259, P=0.004), feel less vulnerable to disease (β=−0.275, P=0.002) and consider less tragic consequences of the disease (β=−0.189, P=0.039). This last dimension appears as the most multi-determined both by the dimensions of IE trait: total IE and Emotional adaptability (β=−0.313, P=0.001) but also by age (β=−0.289, P=0.001) and gender (F=4.74, P=0.03). Adaptability appears as the dimension of EI trait affecting the largest number of beliefs associated with health-related anxiety: Tragic consequences of disease (β=−0.313, P=0.001), responsibility towards illness (β=−0.22, P=0.016), Vulnerability to disease (β=−0.3, P=0.001) and the overall level of health-related anxiety (β=−0.338, P<0.001). In addition, our research confirms that the level of education is independent of the level of EI (F=0.217, P=0.642ns) and secondly, that health-related anxiety was independent of previous individual experiences of illness (F=1.008, P=0.318ns). Analysis of the results to suggest that the level of emotional competence negatively influence the level of anxiety about health, that means that the way people pay attention, process and use emotional information (intrapersonal or interpersonal nature) plays a role in the anxiety about health. These results are consistent with the literature (including Mikolajczak et al., in 2009) and strengthen, if necessary, the moderate nature of emotional competence to deal with stress and anxiety in general. The emotional adaptability was confirmed as a factor influencing the anxiety about health generally and specifically on the tragic perception of consequences of diseases and the subjective perception of personal vulnerability to diseases, but it also appeared as factor acting on the belief in the responsibility for disease. The adaptability is proving to be the dimension of emotional competence that influences more constitutive dimensions of anxiety about health. Our research has also highlighted the lack of linkages, however expected between the dimensions of emotional competence and those of anxiety about health, especially regarding the sociability: characteristic dimension – if necessary – to emotional competence, it is not a factor in the overall level of anxiety about health or its dimensions. However, the analysis show that the level of sociability is related to levels of belief in magical thinking and anxiety about health, which suggests the presence of moderators. This cons-intuitive result is also contrary to previous researches that show a direct positive influence of social support and, by extension, membership as a mechanism of defense, on impact of stress and level of anxiety. Developing emotional competence produces beneficial effects at various levels and is involved in treating various disorders; a therapeutic work focused specifically on developing adaptability, taking into account the specific age and sex, would optimize the management of people with anxiety about health.
