Which of the following is NOT a measure of a client’s motivation?

Ego strength is not typically considered a direct measure of a client's motivation. Instead, ego strength refers to an individual's ability to maintain their ego and manage stress and internal conflicts. While it may have an indirect influence on motivation—since a person with strong ego strength might approach situations with resilience—this trait does not specifically reflect how motivated a client is to engage in therapy or work towards their goals.

On the other hand, goal-setting skills, consistency of attendance, and willingness to engage in therapy directly pertain to how motivated a client is. Goal-setting skills indicate a client’s ability to define and strive for desirable outcomes, which is a clear sign of motivation. Consistency of attendance demonstrates a client's commitment and eagerness to participate in the therapeutic process, while their willingness to engage in therapy illustrates their readiness and motivation to confront and work through their issues. Thus, while ego strength is an important psychological trait, it does not serve as a clear measure of motivation in this context.
