7. Even before you had a chance to do the initial IQ test on James, his teacher had already e-mailed you with concerns about disruptive behavior in class. You conduct a formal observation and you find, using a partial interval recording method, that James’s disruptive behavior occurred during 30% of intervals. The special education administrator wants more details: how do you conduct a partial interval recording-based observation? Under what category of direct observation is it?  What are two features of this category of observation?  What is another category of direct observation?

9. James is referred to Dr. K, a psychologist in private practice, for an ADHD evaluation and the parent allows for communication between Dr. K and the school.  Dr. K would like the teacher to complete the Conners-4 and to receive any other pertinent background documentation.  What are some sources of information you might compile to share with the doctor? Assuming the teacher is not familiar with the Conners-4, list at least three facts you can share with the teacher about this rating scale. Are there any other tests you might want administered, and if so, which ones?

3. Here are the T-scores that you obtain from the raters for the Anxiety subscale: 67 (Valeria), 71 (Ms. Knox), 59 (mother).  Using the BASC-3 scale score classifications, how would you interpret each of these scores in isolation? What are the correct qualitative descriptions? Valeria’s self-report also included an elevated Somatization scale.  What does this scale measure?
