Insights

The Strengths and Difficulties Questionnaire (SDQ) shows good diagnostic accuracy for mental health conditions in extremely preterm children. Combined parent and teacher ratings are recommended for screening, while pervasive ratings offer higher predictive accuracy.

Area of Science:

  • Developmental Psychology
  • Child Psychiatry
  • Pediatric Neurodevelopment

Background:

  • Extremely preterm birth (<26 weeks gestation) is associated with an increased risk of neurodevelopmental and psychological challenges.
  • Accurate screening tools are crucial for early identification and intervention in this vulnerable population.
  • The Strengths and Difficulties Questionnaire (SDQ) is a widely used screening tool for child mental health.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of the SDQ in children born extremely preterm.
  • To compare the effectiveness of different multi-informant rating methods (combined and pervasive) for SDQ assessment.
  • To determine the optimal SDQ rating strategy for identifying specific psychological problems in this cohort.

Main Methods:

  • A cohort of 219 children born extremely preterm (age 11 years) was assessed.
  • Parents and teachers completed the SDQ to screen for psychological issues.
  • Psychiatric diagnoses were established using the Development and Well-Being Assessment for comparison.

Main Results:

  • Pervasive ratings (both parents and teachers agreeing) demonstrated high diagnostic accuracy for emotional disorders, conduct disorders, ADHD, and ASDs, but with low sensitivity.
  • Combined ratings (either parent or teacher agreeing) showed better clinical utility for screening emotional disorders, conduct disorders, and ADHD.
  • Parent ratings were most accurate for identifying Autism Spectrum Disorders (ASDs).

Conclusions:

  • Multi-informant SDQ data are valuable for assessing mental health in extremely preterm children.
  • Pervasive ratings offer superior predictive accuracy as an outcome measure.
  • Combined ratings are effective for screening ADHD, emotional, and conduct disorders, while parent ratings are best for ASDs.

Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Diagnostic and Statistical Manual of Mental Disorders (DSM)

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...
