Insights
The Strengths and Difficulties Questionnaire (SDQ) shows promise for identifying persistent childhood psychiatric disorders. However, its high false-positive rate raises concerns about its clinical utility in low-prevalence primary care settings.
Area of Science:
- Child and Adolescent Psychiatry
- Developmental Psychology
- Public Health Screening
Background:
- Preschool-onset psychiatric disorders can be persistent or transient, impacting long-term outcomes.
- Effective screening tools are needed for early identification and intervention in primary care.
Purpose of the Study:
- To evaluate the screening efficiency of the parent version of the Strengths and Difficulties Questionnaire (SDQP4-16) for persistent versus transient psychiatric disorders in young children.
- To assess the SDQP4-16's ability to differentiate between persistent and transient disorders.
Main Methods:
- A population-based cohort study of 1038 Norwegian children assessed at ages 4 and 6.
- Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnoses were established using the Preschool Age Psychiatric Assessment Interview.
- Receiver operating characteristics (ROC) analysis was employed to compare SDQP4-16 performance against established diagnoses.
Main Results:
- The SDQP4-16 demonstrated higher screening efficiency for persistent disorders (AUC=0.85) than transient disorders.
- The tool could discriminate persistent from transient disorders with an AUC of 0.71.
- A high negative predictive value (99.6%) was observed, but the positive predictive value was low (9.5%) due to low prevalence (1.8%) of persistent disorders.
Conclusions:
- The SDQP4-16 is a sensitive instrument for detecting persistent psychiatric disorders in preschoolers.
- A significant proportion of positive screens represent non-persistent cases, indicated by a high false-positive rate.
- The clinical utility of the SDQP4-16 for primary care screening of persistent disorders is uncertain, especially in low-prevalence populations.
Objective:
To inform primary care screening and preventive intervention efforts, the authors examined the screening efficiency of the parent version of the Strengths and Difficulties Questionnaire (SDQP4-16) for persistent disorders relative to transient disorders and its capacity to distinguish between the two.
Methods:
Persistence and transience in preschool-onset psychiatric disorders were identified by using data from a large population-based cohort study in Norwegian children initially assessed at age 4 and followed up at age 6 (n = 1038). Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnoses at both time points were assigned by using the Preschool Age Psychiatric Assessment Interview, against which the SDQP4-16 was compared through receiver operating characteristics analysis.
Results:
The screening efficiency for persistent disorders exceeded that for transient disorders with a specificity of 86.1%, a sensitivity of 79.3%, and an area under the curve value of 0.85. The SDQP4-16 was able to discriminate persistent disorders from transient disorders at an area under the curve value of 0.71. At the selected cutoff of 10, the negative predictive value was 99.6%, whereas the positive predictive value was 9.5%, partly due to the low prevalence (1.8%) of persistent disorders.
Conclusions:
The SDQP4-16 is a sensitive tool for detecting persistent psychiatric disorders in young children. However, a large proportion of positive screens are nonpersistent cases, as indicated by the high false-positive rate. Thus, the clinical utility of the SDQP4-16 in primary care screening for persistent disorders is uncertain, particularly in samples in which the rate of psychiatric disorders is low.
