Alexitimia: uma revisão do conceito

Adverse Childhood Experiences: Relationship with Empathy and Alexithymia

Several studies showed that adults who have experienced childhood adversity are more likely to develop alexithymia and low empathy. Therefore, this research aims to analyze the relationship between childhood adversity and alexithymia and empathy in adulthood and verify a predictive explanatory model of alexithymia. The sample comprised 92 adults who responded to the sociodemographic questionnaire, the Childhood History Questionnaire, the Interpersonal Reactivity Index, and the Alexithymia Scale of Toronto. Childhood adversity showed a positive relationship with alexithymia and a negative relationship with empathy. Predictive validity showed that marital status, adverse childhood experiences (ACEs), and empathic concern predicted higher alexithymia scores. These results show the impact of these childhood experiences on adult life, underlining the importance of developing intervention programs in this field.

Alexithymia in obese adolescents is associated with severe obesity and binge eating behavior

OBJECTIVE

To study the occurrence of alexithymia in obese adolescents.

METHODS

Cross-sectional study with 102 obese adolescents. Sociodemographic, clinical, and psychometric data (alexithymia and binge eating) were analyzed The Brazilian version of the Toronto Alexithymia Scale and Binge Eating Scale were used for psychometric data collection. Statistical analysis was performed using the Kolmogorov-Smirnov test, Student's t-test, ANOVA, chi-square, linear regression, and logistic regression. The study was approved by Research Ethics Committee.

RESULTS

A 22% occurrence of alexithymia was observed. Considering the category "possible alexithymia", half of the participants presented some alexithymic behavior. Adolescents with alexithymia had higher binge eating scores (alexithymia 16,2 versus possible alexithymia 11,7 versus no alexithymia 8,5; ANOVA p < 0,0005) and three times more binge eating behavior than adolescents with no alexithymia or possible alexithymia (alexithymia 36.4% versus 17.2% possible alexithymia versus 11.8% no alexithymia; chi-square = 6,2, p = 0.04). In simple linear regression, alexithymia scores were positively associated with binge eating scores (r² = 0,4; p = 0,002). Binary logistic regression showed a three times higher probability of an adolescent with severe obesity to meet the criteria for alexithymia.

CONCLUSIONS

There was a 22% occurrence of alexithymia in obese adolescents. It was positively associated with obesity severity and higher binge eating scores, suggesting a relationship between severe obesity, alexithymia, and binge eating behavior.
