Sample interview questions: Can you discuss any experience you have in evaluating the sensitivity and specificity of assessments for different diagnostic purposes (e.g., ADHD, autism)?
Sample answer:
Throughout my career as a Psychometrician, I have been actively involved in evaluating the sensitivity and specificity of assessments for various diagnostic purposes, including ADHD and autism. Here are some key experiences:
ADHD Assessment:
- Conducted a study to determine the sensitivity and specificity of the Conners Continuous Performance Test-3 (CPT-3) for diagnosing ADHD in school-aged children.
- Evaluated the reliability and validity of the parent- and teacher-rated Vanderbilt ADHD Diagnostic Parent and Teacher Rating Scale (VATRS) for assessing ADHD symptoms in children.
Autism Assessment:
- Participated in a multi-site study to develop and validate a new diagnostic tool for autism spectrum disorder (ASD) based on machine learning algorithms.
- Assessed the sensitivity and specificity of the Social Responsiveness Scale (SRS) for identifying children at risk for ASD.
Methodological Approach:
- Employed receiver operating characteristic (ROC) curve analysis to determine the optimal cutoff scores for each assessment, maximizing sensitivity and specificity.
- Used various statistical techniques, such as Cron… Read full answer
