Psychological and behavioral assessments in girls with idiopathic central precocious puberty

Idiopathic central precocious puberty (iCPP) is the most common cause of precocious puberty in girls. However, research on the psychological outcomes of iCPP girls is limited. To evaluated the psychological characteristics in iCPP girls in comparison to prepubertal girls throughout the first diagnosis and six-month follow-up period.

Eighty-five girls, age 6-8 years, and their caregivers were enrolled to the prospective cohort study. Three Thai-standardized questionnaires were used as psychological assessment tools, including Children's Depression Inventory (CDI), Parent Screen for Child Anxiety Related Disorders (SCARED) and Parent-Strengths and Difficulties Questionnaire (SDQ).

Forty-six iCPP and 39 prepuberty girls were enrolled at baseline. No significant differences in psychological and behavioral problems between iCPP and prepuberty girls. However, the iCPP group exhibited a significantly higher proportion of "risk and problem" for emotional problems compares to the prepuberty group (7 vs. 0, p=0.01) while the prepuberty group exhibits the significantly proportion of "risk" for peer problems (6 vs. 0, p=0.007). At baseline, twelve percent of iCPP girls exhibited depression and mean CDI score was 8.1 ± 7.2 and 3.7 ± 2.3 (p=0.007) in iCPP and prepuberty group, respectively. At the 6-month follow-up, there was no significant difference in psychological outcomes between two groups.

There were no significant differences in psychological and behavioral problems in iCPP girls compared to prepubertal girls. However, the higher prevalence of emotional problems and depression observed in iCPP girls constitutes significant psychological issues that necessitate close monitoring.
