In areas where an impairment exists, the CFS should clearly link symptoms with behaviors that lead to the impairment:
"Due to irritability and difficulty regulating her emotions (symptoms), Yolanda has frequent arguments with her roommate/boyfriend (behavior). She has received several warnings about the noise and fighting. This is a problem because it puts her at risk of being evicted and becoming homeless (impairment)."
The CFS is a crucial part of the TCP because in order to provide billable services to a client, we need to show that the impairments we're addressing are the result of their mental illness. The CFS page is where we make that connection.
Most common errors:
1. Not describing specific behaviors
Wrong: "Due to lack of motivation and energy, client has difficulty applying for jobs."
Right: "Due to lack of motivation and energy, client lies in bed all day and won't apply for jobs unless his PSC drives him to the job-site and fills out the application for him."
There's nothing wrong with saying a client has difficulty doing something. Just clarify what you mean and include specific behaviors to back your statement up. Lots of people "have difficulty" getting to work on time, for example, but still manage to do it every day.
2. Not describing significant impairments
Wrong: "Due to irritability and low tolerance for frustration, client at times has difficulty getting along with his girlfriend."
Almost everyone has difficulty getting along with their significant other from time to time. What's described above is not a signifcant impairment. If, on the other hand, the client is getting into big shouting matches that are threatening his housing or putting him at risk of being injured or arrested, a significant impairment exists and you'd include that information in the description.
