In the assessment process, what is the role of collateral information?

• A. Include collateral information to provide context and avoid misinterpretation.
• B. Do not include collateral information; it biases findings.
• C. Rely only on self-report data.
• D. Collateral information should replace standardized data.

Answer: (A)

Collateral information provides context and helps avoid misinterpretation in assessment. It comes from sources other than the client—such as family members, teachers, medical records, and prior evaluations—and offers observations from different settings and times. This information helps triangulate data, check for consistency with self-reports, and clarify how symptoms or functioning manifest across environments. By integrating collateral data with standardized measures and clinical observations, you get a more accurate, nuanced understanding than self-report alone would yield. Remember to obtain appropriate consent and protect confidentiality when gathering collateral information. For example, collateral input can reveal patterns a client may not fully report, guiding more accurate interpretation and planning.
