Geneva Goff appeals from the district court’s 1 order affirming the Commissioner of Social Security’s denial of her application for disability insurance and supplemental security income benefits. Goff claims she is disabled because two strokes have affected her walking, motor capabilities, and speech. She also claims she suffers from depression. On appeal, Goff argues the Administrative Law Judge (ALJ) erred by: 1) failing to give proper weight to the opinions of Goffs treating physician and psychiatrist, 2) discounting her subjective complaints of pain, and 3) finding Goff could perform the work of a companion or personal assistant. We affirm the decision of the district court.
I
In October 1995, Goff suffered a stroke. Following her stroke, she was neurologically normal and her condition was stable. In January 1997, Goff sought help for depression. In March 1997, Goff suffered a second stroke. During this time, she had been working as a Certified Nurse’s Assistant (CNA). She continued work as a CNA until January 2001, when she was fired for allegedly slapping a resident. From early 2001 through the hearing, Goff worked approximately fifteen hours per week as a kitchen aide. Goff filed for disability benefits on January 29, 2001, and for supplemental security income on February 21, 2001, alleging she became disabled beginning January 19, 2001. Goff claimed she was unable to work because multiple strokes caused slurred speech and balance problems. Additionally, she claimed she suffered from depression.
The ALJ determined Goff met the disability insured status requirements of the Social Security Act on January 19, 2001, and continued to meet them through at least December 2005. The ALJ found Goff had not engaged in substantial gainful activity since January 19, 2001. The ALJ further determined Goff suffered severe impairments in combination, consisting of degenerative changes in her knees, more severe on the left; obesity; status post strokes from 1997 with non-severe dysar-thria; depression; and non-severe hearing loss amenable to improvement with a hearing aid. However, the ALJ found Goffs impairments did not meet the Social Security Income Listings.
*789 While the ALJ concluded Goff was unable to perform past relevant work, the ALJ found Goff still retained the residual functional capacity (RFC) to perform work which was limited to lifting 10 pounds frequently and 20 pounds occasionally, and standing and/or walking no more than six hours of an eight-hour day. The ALJ determined Goff should avoid very complex and detailed work, but found she was capable of performing more than merely simple, routine, and repetitive work. In determining Goffs RFC, the ALJ found Goff was forty-nine years old, which is defined as a younger-aged individual; she had a high school education; and she had acquired work skills which were transferable to the skilled or semi-skilled work functions of other work, including feeding and transporting individuals, record keeping, and assisting with activity of daily living.
Further, in determining Goffs RFC, the ALJ concluded the hearing testimony regarding the intensity and severity of Goffs symptoms was not fully credible. At the hearing, Goff testified about the severe pain she experienced after working. The ALJ discounted Goffs subjective complaints because they were inconsistent with the record as a whole. The ALJ also found that Goffs limitations related to her speech and depression were not severe, and her seizures had been controlled with medicine. Additionally, the ALJ found no evidence Goff could not afford pain medication.
The ALJ also discounted certain opinions from two of Goffs treating sources. In early 2001, both Dr. Christopher Okii-shi, Goffs treating psychiatrist, and Dr. Matthew Prihoda, Goffs long-term treating physician, submitted RFC assessments, where they backed Goffs claim of significant limitations. The ALJ did not request clarification from either doctor. Instead, the ALJ discounted both opinions, citing inconsistencies with other objective medical evidence, Goffs activity level, and her work history.
Accordingly, a Vocational Expert (VE), considering Goffs age, education, previous work experience, and RFC, determined jobs still existed in significant numbers in the national economy that Goff could perform. The VE cited personal attendant and companion as examples of such jobs. As such, the ALJ determined Goff was not under a disability as defined by the Social Security Act.

This court reviews
de novo
a district court’s decision upholding the Commissioner’s denial of social security benefits.
Reed v. Barnhart,
The Commissioner’s regulations governing determinations of disability set
*790
forth a five-step sequential evaluation process which the Commissioner must use in assessing disability claims.
See Stormo v. Barnhart,
During the five-step process, the ALJ considers (1) whether the claimant is gainfully employed, (2) whether the claimant has a severe impairment, (3) whether the impairment meets the criteria of any Social Security Income listings, (4) whether the impairment prevents the claimant from performing past relevant work, and (5) whether the impairment necessarily prevents the claimant from doing any other work.
Eichelberger v. Barnhart,
A
Goff contends the ALJ, in determining her RFC, erred by not giving proper weight to the opinions of her long-term treating physician and her treating psychiatrist. “[A] treating physician’s opinion is given ‘controlling weight’ if it is well-supported by medically acceptable clinical and laboratory diagnostic techniques and- is not inconsistent with the other substantial evidence.”
Reed,
In August 2002, Dr. Prihoda, Goffs long-term treating physician, submitted an RFC assessment, where he found, among other things, that Goff could only stand or walk for two to three minutes at one time, could seldom reach with her upper extremities, and could handle objects for less than two hours of an eight-hour work day. The ALJ, finding the opinion inconsistent with other substantial evidence, discounted it. The ALJ pointed out Goff testified she worked five-hour shifts for fifteen to twenty-three hours a week as a kitchen helper, where she was on her feet for about two hours at a time, stacked dishes, lifted sacks of potatoes, and lifted ice buckets. We find this testimony to be substantial, indeed compelling, evidence inconsistent with Dr. Prihoda’s assessment. As such, the ALJ is not required to give the assessment controlling weight. While the ALJ also found Dr. Prihoda’s opinion to be internally inconsistent, we need not comment on that, as an appropriate finding of *791 inconsistency with other evidence alone is sufficient to discount the opinion.
Goff also argues the ALJ erred in failing to give controlling weight to Dr. Okii-shi’s opinion. The ALJ found Dr. Okii-shi’s opinion that Goff suffered extreme limitations was starkly inconsistent with Dr. Okiishi’s opinion in February 2001 that Goffs Global Assessment of Functioning (GAF) was 58. According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), a GAF of 51 to 60 indicates moderate symptoms. American Psychiatric Ass’n, Diagnostic and Statistical Manual of Mental Disorders 32 (4th ed.1994). Thus, Goffs GAF is inconsistent with Dr. Okiishi’s opinion that she suffers from extreme limitations. Additionally, despite Dr. Okiishi’s opinion that Goff would have difficulty maintaining social functioning, Goff stated she was able to relate well with other people and her former employers described her as personable. Again, we find this to be substantial evidence inconsistent with Dr. Okiishi’s assessment, and, as such, the ALJ was not compelled to give controlling weight to the opinion.

Goff next contends the ALJ improperly discounted Goffs allegations of severe and disabling pain. We disagree.
First, Goff argues the ALJ was required to make an express credibility finding on each of the
Polaski
factors.
Polaski v. Heckler,
Next, Goff argues the ALJ disregarded her allegations of pain solely because of the lack of corroborating medical evidence. She further argues the ALJ’s reasons for discounting her credibility are not supported by the record. To establish this, Goff notes that in 2000 her neurologist, Dr. Shavir Pour, stated Goff has mild limitation in her back due to pain and noted Goff complained of one to two small seizures a month. Because of the seizures, Dr. Pour recommended an increase in Depakote to 500 mg twice a day and referred her to a physical therapist to help with her lower back pain and sacroiliac joint pain.
“It is well-settled that an ALJ may not discount a claimant’s allegations of disabling pain solely because the objective medical evidence does not fully support them.”
O’Donnell,
In the instant case, the lack of corroborating evidence was just one of the factors the ALJ considered.
See Kelley v. Callahan,
Second, the ALJ examined Goffs activity level. In
Johnson v. Apfel,
Third, Goff gainfully worked as a nurse’s aide after her second stroke in 1997. The ALJ found no evidence of significant deterioration in her condition since that time. The fact that Goff worked with the impairments for over three years after her strokes, coupled with the absence of evidence of significant deterioration in her condition, demonstrate the impairments are not disabling in the present.
See Or-
*793
rick v. Sullivan,
In passing, Goff also contends the ALJ should not have considered her failure to take prescription medications as an indication that her joint pain was not as severe or limiting as alleged because she could not afford treatment. However, there is no evidence Goff was ever denied medical treatment due to financial reasons. Without such evidence, Goffs failure to take pain medication is relevant to the credibility determination.
See Clark v. Shalala,
Considering the ALJ’s findings regarding other objective medical evidence, Goffs activity level, and Goffs work record, it is apparent the ALJ sufficiently considered her complaints of disabling pain but expressly discredited them for good cause because they were inconsistent with the evidence as a whole. As such, an ALJ may discount Goffs subjective complaints, and we will not disturb the decision.
C
Goff argues the ALJ failed to consider whether the companion and personal attendant positions were realistically suited to Goffs RFC considering her speech impairment and depression. “The RFC is used at both step four and five of the evaluation process, but it is determined at step four, where the burden of proof rests with the claimant.”
Young,
Here, the ALJ found Goffs speech impediment was not as limiting as alleged because Goff effectively worked as a nurse’s aide with her speech impediment and there is no indication that her ability to speak has deteriorated since her stroke in 1997.
See Orrick,
Similarly, the ALJ found Goffs depression was not as limiting as Goff alleged. According to the DSM-IV, a GAF between 51 and 60 is indicative of moderate symptoms or moderate difficulties in social, occupational or school functioning. American Psychiatric Ass’n, Diagnostic and Statistical Manual of Mental Disorders 32 (4th ed.1994). Goffs treating and examining sources regularly ranked her GAF at 60. Thus, her GAF contradicts her assertion of severe mental impairments. Further, Goff testified her antidepressant medication helped her symptoms, and her medical records indicate she was stable on medication. As such, the ALJ’s assessment of Goffs depression in determining her RFC and future gainful em *794 ployment possibilities is supported by substantial evidence.
Goff also claims the hypothetical the ALJ posed to the VE was deficient because “[t]here was no mention of Goffs severe depression, her severe degenerative joint disease, her obesity, her prior history of seizures, or Goffs descriptions of severe pain in her activities of daily living.” “A hypothetical question posed to the vocational expert is sufficient if it sets forth impairments supported by substantial evidence in the record and accepted as true.”
Hunt v. Massanari,
Ill
The judgment is affirmed.
