This cross sectional study of 290 Chinese children aged 8-18 years, evaluated a Chinese version of the self-reported Pubertal Development Scale (PDS) against both raters' and self-reported Tanner assessment of pubertal status. Children completed both the self-reported PDS and self-reported Tanner pubertal questionnaire prior to physical examination through visual depiction by a same gender rater. Puberty Category Scores (PCS) which were derived from the PDS, was used to categorize children into one of five pubertal development stages. Tanner derived composite stage (TDCS) which was derived from the Tanner pubertal questionnaires, was used to compare with PCS to obtain the inter-rater agreement. Moderately high agreements were found between raters' TDCS and PCS in girls [weighted kappa (WK) 0.57 (0.44, 0.71); Kendalltau-b 0.60 (0.51, 0.69)] and in boys [WK 0.58 (0.47, 0.69), Kendalltau-b 0.50 (0.38, 0.62)]. The correlation between self-reported PDS and rater's assessment was substantial in girls [Kendalltau-b 0.61 (0.54, 0.69)] and moderate in boys [Kendalltau-b 0.49 (0.38, 0.61)]. The Hong Kong Chinese children and adolescents were able to reliably estimate their own sexual maturation status (SMS) using a Chinese version PDS. This instrument may be useful in epidemiological studies when cost, privacy and other concerns preclude the use of other SMS assessment tools.
