This study examined the relationship between attachment styles, personality traits, and genetic polymorphism. Insecure attachment styles were associated with higher expression of neuroticism and lower expression of extraversion, conscientiousness, and agreeableness. In individuals carrying the short allele, higher neuroticism and lower extraversion and conscientiousness were observed.
Introduction. The mother and child attachment could have an important and long-lasting impact. An inse-cure attachment could lead to emotional development difficulties. It has been suggested that maternal care in infants is associated with personality. However, more studies in adults are needed. Objective. To deter-mine if attachment styles in subjects with affective or anxiety disorders are associated with the expression of personality traits, and if this effect can be modulated by the presence of the short allele of the 5-HTTLPR polymorphism. Method. Our sample included 87 patients with mood or anxiety disorders. The NEO-PI-R questionnaire and the Adult Attachment questionnaire by Melero were used. Results. Insecure attachment styles were associated with a higher expression of neuroticism, and a lower expression of extraversion, con-scientiousness, and agreeableness, especially in individuals with the most insecure attachment. An interaction was identified between the attachment style and the 5-HTTLPR genotype on the expression of agreeable-ness. Higher neuroticism, and lower extraversion and conscientiousness tended to be present in carriers of the S allele. Discussion and conclusion. There was a significant association between the attachment styles and the expression of neuroticism, extraversion, agreeableness, and conscientiousness-responsibility according to the Big Five Model. The short allele may be associated with the modulation of certain aspects of personality. Prevention strategies should be established to promote adequate attachments between infants and caregivers to avoid a possible risk factor for future maladaptive personality traits.
