Before eating a meal, a client with the obsessive-compulsive disorder must wash the hands for 14 minutes, comb the hair for 114 strokes, and switch the light off and on 44 times. When evaluating the progress of the client, what is the most important objective for this client?

Gradually decrease the time used in performing rituals.

Explanation:

Obsessive compulsive disorder, OCD, is a mental illness that tends to cause repetitive, time-wasting, and unwanted behaviours. It mostly happens when an individual is so keen on arrangement of items or when the individual is afraid of germs.

In this case, when evaluating this client's progress, if the client no longer performs time wasting rituals such as washing the hands for 14 minutes, combing the hair for 114 strokes, and switching the light off and on 44 time, the treatment can be said to be effective.
