Global Assessment of Functioning (GAF) Scale

NRNP – 6640 Psychotherapy Individuals
Number of sources: 5
Paper instructions:
Assessment tools have two primary purposes: 1) to measure illness and diagnose clients, and 2) to measure a client’s response to treatment. Often, you will find that multiple assessment tools are designed to measure the same condition or response. Not all tools, however, are appropriate for use in all clinical situations. You must consider the strengths and weaknesses of each tool to select the appropriate assessment tool for your client. For this Discussion, as you examine the assessment tool assigned to you by the Course Instructor, consider its use in psychotherapy.
Learning Objectives

Students will:
• Analyze psychometric properties of assessment tools
• Evaluate appropriate use of assessment tools in psychotherapy
• Compare assessment tools used in psychotherapy

Note: By Day 1 of this week, the Course Instructor will assign you to an assessment tool that is used in psychotherapy.

To prepare:
• Review this week’s Learning Resources and reflect on the insights they provide.
• Consider the assessment tool assigned to you by the Course Instructor.
• Review the Library Course Guide in your Learning Resources for assistance in locating information on the assessment tool you were assigned.

Post an explanation of the psychometric properties of the assessment tool you were assigned. Explain when it is appropriate to use this assessment tool with clients, including whether the tool can be used to evaluate the efficacy of psychopharmacologic medications. Support your approach with evidence-based literature.

Assessment tools have two primary purposes: 1) to measure illness and diagnose clients, and 2) to measure a client’s response to treatment. For the Week 2 discussion, you will examine the assessment tool that I have assigned to you and consider its use in psychotherapy.

Global Assessment of Functioning (GAF) Scale

The Global Assessment of Functioning (GAF) Scale is a numeric scale used by mental health clinicians and physicians to rate subjectively the social, occupational, and psychological functioning of an individual, i.e., how well one is meeting various problems in living. Scores range from 100 (extremely high functioning) to 1 (severely impaired). The scale was included in the Diagnostic and Statistical Manual of Mental Disorders (DSM) version 4 (DSM-IV), but replaced in DSM-5 with the World Health Organization Disability Assessment Schedule (WHODAS), a survey or interview with detailed items.

The GAF Scale is a useful tool for clinicians to assess the overall level of functioning of a client. It can be used to track changes in functioning over time, to compare the functioning of different clients, and to make decisions about treatment. The GAF Scale is also used by insurance companies to determine the level of care that a client needs.

The GAF Scale has been criticized for being subjective and for having poor psychometric properties. However, it remains a widely used tool in mental health practice.

Psychometric Properties of the GAF Scale

The GAF Scale has been shown to have poor reliability and validity. Reliability refers to the consistency of scores over time, while validity refers to the accuracy of scores. The GAF Scale has been shown to have low test-retest reliability, meaning that scores on the scale are not consistent over time. The GAF Scale has also been shown to have low concurrent validity, meaning that scores on the scale are not consistent with other measures of functioning, such as the Social Adjustment Scale-II (SAS-II).

Despite its poor psychometric properties, the GAF Scale remains a widely used tool in mental health practice. This is likely due to the fact that it is a quick and easy tool to use. The GAF Scale can be completed in a few minutes, and it does not require any specialized training.

When to Use the GAF Scale

The GAF Scale is most appropriate for use in the following situations:

To track changes in functioning over time
To compare the functioning of different clients
To make decisions about treatment
To meet insurance company requirements
The GAF Scale should not be used in the following situations:

To diagnose mental disorders
To make decisions about medication
To make decisions about hospitalization
Conclusion

The GAF Scale is a useful tool for clinicians to assess the overall level of functioning of a client. However, it is important to be aware of the limitations of the scale. The GAF Scale should not be used as the sole basis for making decisions about diagnosis, treatment, or medication.
