Attention-deficit/hyperactivity disorder and alexithymia: a pilot study.

Although the relationship between alexithymia and psychopathology has been studied extensively in adults, research is lacking on alexithymia in childhood psychopathology. The aim of this study was to investigate the relationship between alexithymia and attention-deficit/hyperactivity disorder (ADHD). The Italian version of the Alexithymia Questionnaire for Children was administered to a sample of 50 children with a DSM-IV diagnosis of ADHD, as assessed by means of the K-SADS PL, and to 100 healthy, age- and sex-matched children without ADHD. The total alexithymia score as well as the difficulty in identifying feelings (DIF) and externally oriented thinking factors were significantly associated with ADHD. The total alexithymia score, the DIF, and the difficulty in describing feelings factors were also significantly associated with symptoms of hyperactivity/impulsivity. No significant relationship between alexithymia and inattentiveness symptoms emerged. Results provide preliminary data on the relationship between alexithymia and ADHD. Findings point to an association between difficulty in identifying emotions and hyperactivity/impulsivity. Future studies conducted on larger patient samples, as well as longitudinal designs, are warranted to confirm our findings.

The Junior Temperament and Character Inventory: Italian validation of a questionnaire for the measurement of personality from ages 6 to 16 years.

The Junior Temperament and Character Inventory (JTCI) has been developed for the assessment of the personality in individuals 6 to 14 years old according to the psychobiological model of Cloninger. The aim of the present study was to evaluate the psychometric properties of an Italian version of JTCI. The sample included 459 subjects ranging in age from 6 to 15.9 years. Starting from the original parent version, an Italian version of JTCI was developed and administered to parents recruited in primary schools of Lazio and Campania. Using statistically appropriate methods for the analysis of dichotomous variables (binary coded), we analyzed the factor structure, the internal consistency, and the test-retest reliability. The architecture of the JTCI was consistent with the original hypothesis of the Cloninger model. Parent reports of each of the JTCI dimensions had good internal consistency and test-retest reliability over 3 months. Regarding the analysis of risk personality traits, significant correlations were found between several JTCI factors and Strengths and Difficulties Questionnaire scales. The JTCI is useful in research and in clinical practice to evaluate the role of temperament and character dimensions in psychopathology.
