GBI results write-up[edit source]

First of all, a huge thank you for Dr. Youngstrom and all of you who have devoted so much time and effort into this exceptionally valuable resource. :0)

Will give me some feedback? I have placed below a write-up for a hypothetical case. Although the data I present below and my questions are in "case study" format, I primarily want to enhance my understanding of the GBI and I'm using a hypothetical case as the vehicle to solicit your insights and suggestions. In general, I find this method—case-based learning—to be one of the best ways for me (and others) to learn and understand.[1]

I'm looking for two types of feedback:

(1) Did I analyze and interpret the scores correctly? Did I miss any research articles with information relevant to this particular case (in terms of scoring and interpretation)?

(2) Did I explain the results accurately? (I intentionally do not explain terms such as "diagnostic likelihood ratio" because I have a detailed feedback session with the evaluee and explain terms as needed, and anyone else reading the report now or in the future should either know the terms or can easily look them up.)

Here are is my GBI write-up. The hypothetical evaluee is a young adult. // Thank you!

General Behavior Inventory (GBI)

Scoring method →

Scale ↓

Caseness Scoring Dimensional Scoring
Depression 17 64
Hypomanic-Biphasic 14 46

PATIENT’s caseness scores for both scales are above the cut-off scores provided in one study (cut-off scores: Hypomanic-Biphasic ≥ 13 and Depression ≥ 11) with a nonclinical college sample,[2] but below the cut scores in another study (cut-off scores: Hypomania-Biphasic ≥ 17 and Depression ≥ 23) with a combined college clinical-training clinic and community mental health center sample.[3]

Based on a third study, which used dimensional scoring with an older adolescent to young adult sample,[4] PATIENT’s Hypomanic-Biphasic dimensional score is above the cut-off score of 20, which yields a diagnostic likelihood ratio of 3.16.[5]

Assuming an estimated 10% prevalence rate for bipolar spectrum disorders in our clinic, the likelihood of a bipolar disorder diagnosis for PATIENT is about 32%.[a] Thus, PATIENT’s GBI results suggest a possible bipolar diagnosis, with a unipolar depression diagnosis being more likely—based solely on the GBI scores, i.e., not considering the results of the other assessment procedures.   - Mark D Worthen PsyD (talk) 18:41, 13 October 2021 (UTC)[reply]
