The present study aimed to investigate the relationship between unexplained chest pain in children with parents’ mental problems, parental attitudes, family functionality, and the child’s mental problems.

A total of 433 children (between 11 and 18 years of age) applied to the Pediatric Cardiology Outpatient Clinic due to chest pain in the last year. A clinical interview was conducted by a child psychiatrist with 43 patients and 33 controls included in the study due to unexplained chest pain.

Family history of physical illness was significantly higher in the chest pain group. When evaluated in terms of psychosocial risk factors, life events causing difficulties, derangement in the family, loss of a close person, and exposure to violence were statistically significantly higher in the group with chest pain. Mental disorders were observed in 67.4% of the children in the chest pain group as a result of the clinical interview. The total score of the DSM-5 somatic symptoms scale, which evaluates other somatic complaints in the chest pain group, was also significantly higher. When the family functions of both groups were evaluated, communication, emotional response, behaviour control, and general functions sub-dimensions were statistically significantly higher in families in the chest pain group.

We recommend that psychiatric evaluation be included in diagnostic research to prevent unnecessary medical diagnostic procedures in children describing unexplained chest pain, as well as to prevent the potential for diagnosing mental disorders in both children and adults.
