Tamika is an 11 year old African American female in regular education. Her mother sought treatment for her increased anger, aggression, being “hyper,” having trouble sleeping, lying, talking to herself, and stealing. At home, she was often cranky and refused to share things with her two siblings and younger cousin, who were all living in the same house. When she had tantrums, she screamed, threw things, broke a plate and some toys, and escalated to the point that the mother worried she might injure someone. Tamika is starting to have problems at school, including lower grades and disruptive classroom behaviors such as talking out of turn, getting easily distracted, and frequently arguing with peers and some teachers.
Tamika, her mother, and her teacher all completed the Achenbach System of Empirically Based Assessment (ASEBA) checklists. Here are the results, reported as T scores (M = 50, standard deviation (SD) = 10, compared to other women between 11 and 18 years of age).
Mental status and clinical observations
Diagnostic interview findings
Diagnoses are based on a LEAD (Longitudinal expert evaluation of all data) consensus meeting following a Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS) interview, using DSM-IV criteria. The same interviewer met with Tamika, and then her mother, then discussed any differences of opinion with them as needed to use clinical judgment. KSADS results were reviewed with a licensed clinical psychologist to arrive at a final decision.
- PTSD (100% confidence post interview)
- ADHD (65% confidence post interview)
- ODD (70% confidence post interview)
- Rule out: reactive attachment disorder (49% confidence post interview)
- Rule out: mood NOS (33% confidence post interview)
Cognitive and achievement testing
(Not done as part of the evaluation; may be able to match up information later)
Let's see how we would apply the EBA principles to Tamika.
Shortlist of Probable Hypotheses
Based on Tamika's age and the common clinical issues, here are the possible issues:
- Post traumatic stress disorder definitely is a leading hypothesis based off of interviewer report scores.
- Oppositional defiant disorder should be another hypothesis, based on her high externalizing scores across different reporting groups, and especially from her mother.
- Conduct problems would be a third possible diagnosis.
- Attention problems are worth evaluating based on prevalence, though her prior academic performance does not suggest any additional reason for concern.
Tamika's gender and age make her on the bubble between oppositional defiant disorder and conduct disorder, for which she is on the younger side of the range.

Mention that these have DLRs. Also unpack the implications of agreement and disagreement for the client (and add a section about treatment implications of disagreement on the Conceptual Model Pages)
The diagnostic interview suggests a combination of a major depressive episode and a prior dysthymia, sometimes referred to as a "double depression." This suggests that Arlene's stress and mood problems have persisted for a long time, and may be more difficult to treat. The mood disorders clearly are associated with impairment and should be a major focus of treatment.
The double depression is a moderating factor suggesting worse prognosis, along with potential demoralization and early drop out from treatment.
Arlene was originally leaning towards an antidepressant medication, thinking that she could take it without telling her parents. After discussing the pros and cons of medication (including the effect size in youths, the potential side effects, and the fact that her parents would find out as part of the consent process), as well as the pros and cons of different evidence based therapies, she elected to try IPT. She wanted to revisit the possibility of a stimulant helping with her inattention, but she opted to wait and see if that improved along with her mood if the IPT helped.
Reliable Change Index
Pick a treatment target and specify what the RCI would be for it. Discuss how you would explain to Arlene.
Given Arlene's main diagnosis with a combination of a major depressive episode and a prior dysthymia, bringing down her depressive symptoms back
A, B, Cs of Jacobson definitions. General stuff about limitations would go on the main concept page. Here it is focused on the client -- what are the benchmarks they will focus on? How explained to them?
Minimum Important Difference (MID)
Note that this section is a dangler -- not originally called out in the 12 steps. Medium d as a rule of thumb from Streiner, Norman, & Cairney (2015). Could work from AUC to d to raw units as a way of estimating, since psychology hasn't done research on this yet. Might be able to back into it with studies that had CSQ and outcome data.
Client Goals & Tracking
These would be personal goals and idiographic measurement -- YTOPS, etc.
This would be traces such as coming to sessions, doing homework assignments. (Not sure of other specifics involved in current IPT protocols?)
YTOPS again and goal setting.
Revisit Jacobson benchmarks. Is there much chance of relapse? What things would the client need to pay attention to if they were going to nip that in the bud?
