The DSM-5 was published in May 2013 and it appears the GAF Scale is no longer being used in DSM-5.
Below I’ve quoted from dsm5.org website. After that quote I have also included the GAF Scale from the DSM-IV for reference purposes.
“With the removal of the multiaxial system in DSM-5, how will disability and functioning be assessed? The Global Assessment of Functioning (GAF) scale, recommended for Axis V in the DSM-IV, was used for determinations of medical necessity for treatment by many payers, and eligibility for short- and long-term disability compensation. Clinician-researchers at the APA have conceptualized need for treatment as based on diagnosis, severity of symptoms and diagnosis, dangerousness to self or others, and disability in social and self-care spheres. We do not believe that a single score from a global assessment, such as the GAF, conveys information to adequately assess each of these components, which are likely to vary independently over time.
Therefore, we are recommending that clinicians continue to assess the risk of suicidal and homicidal behavior and use available standardized assessments for symptom severity, diagnostic severity, and disability such as the measures in Section III of DSM-5 (online at https://www.psychiatry.org/practice/dsm/dsm5/online-assessment-measures). For those who relied on the use of a GAF number, we expect there will be a transitional period from the GAF to the use of separate assessments of severity and disability.
The World Health Organization Disability Assessment Schedule (WHODAS 2.0) was judged by the DSM-5 Disability Study Group to be the best current measure of disability for routine clinical use. The WHODAS 2.0 is based on the International Classification of Functioning, Disability, and Health (ICF) and is applicable to patients with any health condition. The scale, as well as scoring information is included in Section III of DSM-5.” Frequently Asked Questions about DSM-5 Implementation- For Clinicians UPDATED 8/1/13
For Reference the GAF Scale below is from the DSM-IV
The GAF is a 100-point tool rating overall psychological, social and occupational functioning of people over 18 years of age and older. It excludes physical and environmental impairment. The GAF is included in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) in the section on multi-axial assessments.
100 – 91 Superior functioning in a wide range of activities, life’s problems never seem to get out of hand, is sought out by others because of his or her many positive qualities. No symptoms.
90 – 81 Absent or minimal symptoms (e.g. mild anxiety before an exam), good functioning in all areas, interested and involved in a wide range of activities, socially effective, generally satisfied with life, no more than everyday problems or concerns (e.g., an occasional argument with family members).
80 – 71 If symptoms are present, they are transient and expectable reactions to psychosocial stressors (e.g., difficulty concentrating after family argument); no more than slight impairment in social, occupational, or school functioning (e.g., temporarily falling behind in schoolwork).
70 – 61 Some mild symptoms (e.g., depressed mood and mild insomnia) OR some difficulty in social, occupational, or school functioning (e.g., occasional truancy, or theft within the household), but generally functioning pretty well, has some meaningful interpersonal relationships.
60 – 51 Moderate symptoms (e.g., flat affect and circumstantial speech, occasional panic attacks) OR moderate difficulty in social, occupational, or school functioning (e.g., few friends, conflicts with peers or co-workers).
50 – 41 Serious symptoms (e.g., suicidal ideation, severe obsessional rituals, frequent shoplifting) OR any serious impairment in social, occupational, or school functioning (e.g., no friends, unable to keep a job).
40 – 31 Some impairment in reality testing or communication (e.g., speech is at times illogical, obscure, or irrelevant) OR major impairment in several areas, such as work or school, family relations, judgment, thinking, or mood (e.g., depressed man avoids friends, neglects family, and is unable to work: child frequently beats up younger children, is defiant at home, and is failing at school).
30 – 21 Behavior is considerably influenced by delusions or hallucinations OR serious impairment in communication or judgment (e.g., sometimes incoherent, acts grossly inappropriately, suicidal preoccupation)OR inability to function in almost all areas (e.g., stays in bed all day; no job, home, or friends).
20 – 11 Some danger of hurting self or others (e.g., suicide attempts without clear expectation of death, frequently violent; manic excitement) OR occasionally fails to maintain minimal personal hygiene (e.g., smears feces) OR gross impairment in communication (e.g., largely incoherent or mute.
10 – 1 Persistent danger of severely hurting self or others (e.g., recurrent violence) OR persistent inability to maintain minimal personal hygiene OR serious suicidal act with clear expectation of death.
