Final answer:
A client shows their commitment to overcoming depression by acknowledging their personal agency and willingness to change, which is 'I need to make a voluntary choice to stop my feelings of depression'.
Step-by-step explanation:
How a client might express their commitment to overcoming feelings of depression is by recognizing their ability to control their own outcomes and taking responsibility for initiating change. A positive statement reflecting this mindset is, "I need to make a voluntary choice to stop my feelings of depression." This attitude aligns with Seligman's hopelessness theory, indicating a move away from learned helplessness and towards a sense of personal agency. Instead of viewing depression as something beyond their control or an inevitable part of life, acknowledging their own power to make changes reflects a commitment to overcoming the condition. Effective treatments for depression, such as psychotherapy and medication, can be more successful when the individual engages actively in the recovery process and beliefs like having control over personal outcomes are reinforced.
