There are a number of patient-centered measures that have been developed to assess the health outcomes of patients. Most of these measures were developed in the 20 th century, and studies have proved that they are reliable, valid and responsive to important clinical changes (Kazis et al., 2004). Currently, there are several surveys for evaluating the quality of life or health outcomes of patients. Most of these measures can be used interchangeably regardless of their differences in item content and response choice differences. One of the survey tools that is widely used to assess the health outcomes of patients is the Medical Outcome Survey (MOS) (Nachar et al., 2013). MOS is used in different avenues of care. This paper will delve into discussing how MOS is used in psychotherapy. The paper will outline the psychometric properties of MOS. Lastly, the paper will state when it is appropriate to use MOs and the appropriateness of MOS in evaluating the efficacy of psychopharmacologic medications.
MOS is used in psychotherapy to measure health outcomes of patients with mental illnesses, such as patients with trauma, depression, schizophrenia, and anxiety. The tool is also commonly used to treat the health outcomes of patients with stroke, cancer, and HIV. MOS has good psychometric properties. Numerous studies document that MOS is reliable for measuring the health outcome of patients (Rejas et al., 2007; Khuong et al., 2018). According to Rejas et al. (2018), MOS has good psychometric properties. According to Rejas et al. (2018), MOS is reliable and valid for measuring changes in patients with NeP of broad aetiology. MOS is sensitive to changes in patients. In another study, Khuong et al., (2018), showed that MOS is a reliable, valid, and responsive to measuring social support in patients engaging in methadone maintenance treatment (MMT). Overall, MOS has good psychometric properties.

MOS rely upon patient self-reporting. With this in mind, this tool should be employed in managed care organization and health insurance agencies. For example, Medicare use this tool for routine monitoring and assessment of health care outcomes of patients, particularly adult patients. MOS is used when a health care facility or an organization, such as managed care organizations, want to determine the variations in the health outcomes of patients. It is also used when one wants to develop more practical tools for routine measuring of patient outcomes. Research studies also employ this tool when conducting studies that involve measuring the health outcomes of participants. In this regard, MOS is widely used in large epidemiological studies (Holden et al., 2004).
With regard to psychopharmacologic medications, MOS can be used to evaluate the effectiveness of psychopharmacologic treatments in a real-world setting. In one study, the tool was used to evaluate the effectiveness of risperidone long-acting therapy (RLAT) in the treatment of schizophrenia (Macfadden et al., 2011). The tool effectively evaluated the efficacy of RLAT.
To sum up, MOS is one of the patient-centered measures used to assess the health outcomes of patients. In psychotherapy, the tool is used to measure the health outcomes of patients with trauma, depression, schizophrenia, and anxiety. MOS has good psychometric properties. The tool is widely employed by managed care organizations and Medicare. These organizations use it for routine monitoring and assessment of health care outcomes of patients. MOS can also be used to evaluate the efficacy of psychopharmacologic medications.
