Which assessment tool focuses specifically on the psychological aspects of health?

The Symptom Checklist-90-R is a widely recognized assessment tool specifically designed to evaluate various psychological symptoms and distress levels in individuals. This instrument comprises a range of symptoms reflecting various psychological disorders, such as anxiety, depression, and somatization, allowing practitioners to assess an individual's mental health comprehensively.

The structure of the Symptom Checklist-90-R, which includes 90 items rated on a Likert scale, facilitates the identification of psychological issues that may impact a person's overall well-being and functioning. By focusing on psychological symptoms, the tool helps clinicians determine the presence and severity of these issues, enabling them to devise appropriate treatment plans and interventions.

Although other assessment tools mentioned may focus on various aspects of health, they do not specialize exclusively in the psychological domain as the Symptom Checklist-90-R does. This makes it the most suitable choice for assessing the psychological aspects of health among the given options.
