A client reports having infrequent, but extremely disturbing, tactile hallucinations. The MOST useful way to gather information about this person would involve:

A) self-monitoring.
B) naturalistic observations.
C) structured observations.
D) a neuropsychological battery.

Self-monitoring is the most useful way to gather information about infrequent but extremely disturbing tactile hallucinations because it allows the client to record their experiences in real-time or close to the occurrence of the hallucinations. This method provides detailed and specific information about the context, frequency, intensity, and triggers of the hallucinations, which might not be captured as effectively through other methods.
