BackgroundScreening for developmental disorders is an important task for Child Health Care. The concept of ESSENCE (early symptomatic syndromes eliciting neurodevelopmental clinical examinations) was created to cover all types of early developmental disorders and the ESSENCE-Questionnaire (ESSENCE-Q containing 12 questions with possible total scores ranging from 0 to 22) was developed as a tool for early detection of these disorders. The aim of this study was to perform a validation study in a public health situation in Japan.MethodsThe psychometric properties of the ESSENCE-Q, completed by mothers, public health nurses (PHNs), and psychologists at 18-month (n=143 children) and 36-month (n=149 children) checkups were evaluated in a small city of Japan. Results were validated against clinical ESSENCE diagnoses. Receiver operating characteristic curves were generated and compared by using the area under the curve (AUC). Optimal cutoff values were explored.ResultsAt the 18-month checkup, AUC by mothers was 0.72, by PHNs 0.86, and by psychologists 0.82. An optimal cutoff was 3 with a high negative predictive value (NPV). At the 36-month checkup, AUC by mothers was 0.57, by PHNs 0.82, and by psychologists 0.87. Optimal cutoff was 2 with high NPV.ConclusionThe ESSENCE-Q completed by PHNs and psychologists had good diagnostic validity. The results suggested that almost all children scoring under cutoff would not have any ESSENCE problems/diagnoses.

CONCLUSION: Women with endometriosis and menstrual problems were at risk of developing postpartum depression. This study suggests a perinatal mental health screening for predisposed women.

Aim Our aim was to extend the validity of a questionnaire developed for screening and identifying early symptomatic syndromes eliciting neurodevelopmental clinical examinations‐questionnaire (ESSENCE‐Q) in young children. Methods Early symptomatic syndromes eliciting neurodevelopmental clinical examinations‐questionnaire data for 207 children, living in Aki City, Japan, in 2014‐2015, were obtained from mothers, public health nurses and psychologists at 20‐ and 40‐month routine check‐ups at child healthcare centres. These were checked against subsequent ESSENCE diagnoses made by physicians. Receiver operating characteristic curves were constructed, and the area under the curves was compared. Sensitivity, specificity, positive predictive values (PPVs) and negative predictive values were calculated at optimal cut‐off values. The clinical utility index was also calculated. Results When the ESSENCE‐Q was used by public health nurses, it demonstrated good validity, in terms of high sensitivity and high NPVs, at the 20‐month check‐up, but not at 40 months. Psychologists demonstrated good validity at both ages, but mothers did not. Good negative utility indexes, indicating screening accuracy, were obtained from the psychologists at both check‐ups and from nurses at 20 months. Conclusion The ESSENCE‐Q results used by nurses and psychologists showed good validity. Future studies should confirm the effectiveness of this tool to identify children in need of clinical detailed neurodevelopmental assessment.
