Clinical utility of the Background Interference Procedure for the Bender-Gestalt test
Journal of Clinical Psychology
|July 1, 1982
Summary
The Background Interference Procedure (BIP) Bender-Gestalt test shows low reliability for screening brain dysfunction. Its diagnostic validity is questionable, with lower accuracy than previously reported, limiting its use for detecting brain damage.
Area of Science:
- Neuropsychology
- Clinical Psychology
Background:
- The Background Interference Procedure (BIP) is a version of the Bender-Gestalt test.
- It is used as a screening tool for organic brain dysfunction.
Purpose of the Study:
- To review evidence on the validity of the BIP for screening organic brain dysfunction.
- To assess the diagnostic accuracy of the BIP in a clinical population.
Main Methods:
- A literature review of BIP validation studies was conducted.
- A study compared the BIP's performance against EEG and neuroradiological procedures in brain-damaged and non-impaired male inpatients.
Main Results:
- Evidence suggests low reliability and validation shortcomings for the BIP.
- The BIP's hit rate (61%) and relative accuracy were lower than reported in prior studies.
- BIP performance was inferior to EEG and neuroradiological methods.
Conclusions:
- The diagnostic validity of the BIP as a screening test for organic brain dysfunction is limited.
- The BIP's utility in detecting brain damage is questionable.
- A potential application of the BIP may lie in assessing constructional praxis.
