General Behavior Inventory (GBI)

How to use our General Behavior Inventory template

This self-report GBI template aids mental health professionals in evaluating symptoms of bipolar affective disorders. Follow these steps to make the most of this free resource:

Step 1: Access the template

Download the General Behavior Inventory template by following the link on this page or by searching for it in Carepatron's free template library.

Step 2: Input patient information

Instruct the patient to provide their information (including name and contact details) at the top of the form. Ensure they carefully read and understand the instructions.

Step 3: Complete the questionnaire

Instruct the patient to complete the questionnaire by rating how frequently each behavior occurs. There are 73 items that count towards their score, and three final validation questions. All questions must be answered.

Scoring

The total score indicates whether the participant's behavior is consistent with bipolarity, and the clinical significance of those symptoms. GBI items can be divided into three categories; those that assess depression, those that assess hypomania and mania, and those that assess biphasic behavior (fluctuations between depressive and hypomanic behavior).

Total GBI scores reflect the number of behaviors for which the participant has reached the syndromal threshold (i.e. the duration, frequency and intensity of the behavior is high enough to be considered atypical/to meet diagnostic criteria). Note that the scale is also sensitive to subsyndromal tendencies or behaviors, which can help identify those who may be at risk of developing bipolar disorder or show early symptoms, but do not yet meet diagnostic criteria.

To obtain an overall score, sum the points (from 0-3) for each of the 73 items. While there are no established cutting scores applicable for every population, higher scale scores indicate increased psychopathology.

The GBI can also be modified to detect unipolar depressive tendencies by producing two separate scores for the items that make up the depression sub scale and those that make up that hypomanic/manic sub scale. A high score on the depression scales, but a low score on the mania scales indicates unipolar depression.

Next steps after using the GBI

Here are some possible next steps after conducting the GBI:

Further assessment

If the patient's results are not consistent with bipolar disorder, you may need to conduct further psychological screenings to correctly diagnose any significant symptoms (they may be presenting with another disorder).

If their results are consistent with bipolar affective disorder, it is important to conduct further tests to evaluate their risk and severity level. Clinical evaluations are needed to confirm a diagnosis.

Intervention

For those flagged as having subsyndromal bipolar tendencies, early intervention is key to prevent their condition progressing into fully syndromal bipolar disorder. This is especially key for young patients at the typical 'age and stage' prior to full symptom onset.

Confirmatory assessment

The GBI is a self-report measure and therefore subject to reporter biases, so it is important to evaluate several sources during the diagnostic process. This is especially important for young clinical patients, as adolescent psychopathological disorders are often misdiagnosed. If the initial youth report GBI screening indicates a high degree of psychopathology, conduct the parent report (P-GBI) and teacher report GBI to create a more informed diagnosis.
