In gathering background information, which of the following is NOT a category used?

In the context of gathering background information for treatment recovery, it is essential to rely on objective data rather than subjective viewpoints. The inclusion of personal opinions from the counselor does not serve as a reliable category for background information. This is because personal opinions can be biased and may not accurately reflect the client's situation.

On the other hand, previously gathered assessment information, current presentation findings, and collateral information from family or school are all critical categories utilized to build a comprehensive understanding of a client's background. These elements provide factual, concrete insights that inform treatment planning and interventions. They ensure that the context, environment, and previous assessments contribute to a holistic view, which is pivotal in effective treatment recovery practices.
