Liza Strongson appeals from the district court’s 1 order affirming the Administrative Law Judge’s (ALJ) denial of her application for disability insurance benefits and supplemental security income. Because the decision of the ALJ is supported by substantial evidence, we affirm.
I.
Strongson, a 45-year-old woman with an eleventh grade education, claims that she has been disabled since July 12, 1999, as a result of fibromyalgia, reflex sympathetic dystrophy in her left arm, arthritis in her left knee, depression, and panic disorder. Her past work included the sales of automobiles, cosmetics, and computers, and included some management positions. Her most recent job as a computer sales representative, which she conducted from her own home, ended on July 12, 1999, when she was terminated because of her inability to perform up to expectations. Her application was denied initially, upon reconsideration, and after a hearing before the ALJ.
The ALJ conducted the five-step analysis prescribed by the social security regulations.
See Krogmeier v. Barnhart,
Strongson alleges on appeal that the ALJ improperly determined her RFC because he ignored the medical opinions of her treating sources and because he failed to apply the appropriate legal standard in evaluating her credibility.
II.
We review de novo a district court decision affirming a denial of social security benefits and uphold the ALJ’s decision if substantial evidence supports his findings.
O’Donnell v. Barnhart,
The ALJ should determine a claimant’s RFC “based on all the relevant evidence, including the medical records, observations of treating physicians and others, and an individual’s own description of his limitations.”
McKinney v. Apfel,
The claimant is capable of lifting and carrying up to 20 pounds occasionally, with more frequent lifting and carrying being limited to 10 pounds. No significant limitations exist with regards to the claimant’s ability to sit, stand and or walk in a vocational capacity, but she should not be required to ... perform activities requiring her to balance. The claimant has full use of the dominant right hand, but ... she is not able to repetitively use the left hand for reaching, handling or fingering. Significant mental and cognitive limitations also are present. While she can pay attention well enough to carry out a simple routine or repetitive activity, she cannot, [sic] sustain a high level of concentration, persist with precision work or work requiring attention to detail. She should avoid stressful work, should avoid fast-paced work, and should not be expected to adhere to explicit production quotas, deadlines or schedules. The claimant is not able to withstand the stress of changes in work settings.
ALJ Decision of Dec. 7, 2000, at 11.
A.
Strongson contends that the ALJ improperly ignored medical opinions about her functional and vocational abilities. Strongson does not contend that the ALJ ignored all of her treating sources, but challenges only the ALJ’s conclusions about her mental impairments, suggesting that the ALJ substituted his own opinion for that of the medical personnel who were giving her psychological treatment. She argues that the ALJ improperly disregarded the opinion of her psychologist, Dr. Harold Wolff, by assigning “little probative value” to Dr. Wolffs opinion. She also asserts that the ALJ’s failure to request the treatment notes or opinions of Strong-son’s therapist, Carol Diamond, a licensed clinical social worker, constituted a dereliction of his duty to develop the record.
The ALJ should give more weight to the opinion of doctors who have treated a claimant regularly over a period of months or years because they have a “longitudinal picture of [the] impairment.”
Shontos,
In June 2000, Dr. Wolff, who had treated Strongson from October 1997 to March *1071 2000, wrote a letter and completed a medical source statement about Strongson’s condition and limitations. A.R. at 429-32. He described her condition as having improved, noted some success with medications, and expressed the belief that there was a “reasonable chance” that she would further improve in her psychiatric status. The medical source statement requires the responding physician to rank the patient’s functional abilities as “not significantly limited,” “moderately limited,” “markedly limited” or “extremely limited.” In completing the document, Dr. Wolff indicated numerous areas in which Strongson was not significantly limited and noted several moderate limitations related to understanding and carrying out instructions and responding to criticism, deadlines or changes in the work setting. The only area in which he believed Strong-son was markedly limited, however, was in her ability to complete a normal workday without interruption from psychologically-based symptoms and the need for significant rest periods. A.R. at 432. Dr. Wolff concluded his letter by stating that although as of his last interview with her (March 16, 2000), he regarded Strongson “as still vocationally impaired, [I] cannot say that she is permanently so.” A.R. at 429.
The ALJ specifically noted that Dr. Wolffs opinion was “without explanation or support from clinical findings” and was “not internally consistent with [his] own treatment notations.” ALJ Decision of Dec. 7, 2000, at 10. We believe that substantial evidence in the record supports this conclusion. It was reasonable for the ALJ to give little probative value to the conclusory statement that Strongson was vocationally impaired because it was neither within Dr. Wolffs expertise to determine vocational ability nor consistent with his findings of little to moderate limitations in all of Strongson’s cognitive and other functional abilities. The ALJ did not reject the moderate limitations Dr. Wolff indicated that Strongson was subject to but instead incorporated many of them directly into the description of Strongson’s RFC, which found that that her significant mental and cognitive limitations prevent her from maintaining high-level concentration, doing precision work, performing stressful or fast-paced work, meeting quotas or deadlines, and adapting to changes in her work setting or schedule. See ALJ Decision of Dec. 7, 2000, at 11. The other psychological evaluation in the record by one-time examiners R.R. Cottons, PH.D. and David W. Bailey, PSAT, indicates similar functional limitations, in particular limitations in concentration and the ability to perform stressful, fast-paced or detailed work, but it does not conclude that Strong-son is entirely unable to work.
Strongson argues that Ms. Diamond’s opinion was necessary to a fully developed record and that the ALJ erred in not requesting it. It is improper for the ALJ to ignore opinion evidence from a therapist that is in the record and provides unique uncontroverted evidence of an impairment.
See Shontos,
As our court so recently and forcefully pointed out, it is well settled that it is the ALJ’s duty to develop the record fully and fairly.
Snead v. Barnhart,
B.
Strongson contends that the ALJ failed to conduct an appropriate analysis in the process of judging the credibility of her testimony and her subjective complaints of pain. In analyzing a claimant’s subjective complaints of pain, an ALJ must examine several factors: (1) the claimant’s daily activities; (2) the duration, frequency and intensity of the pain; (3) the dosage, effectiveness and side effects of medication; (4) precipitating and aggravating factors; and (5) functional restrictions.
Brown v. Chater,
The ALJ need not explicitly discuss each
Polaski
factor.
Brown,
The ALJ found that Strongson’s testimony was “not fully credible, especially to the extent that her allegations would suggest that she is totally incapacitated for any type of work.” ALJ Decision of Dec. 7, 2000, at 8. He stated that her testimony at the hearing was inconsistent with the reports of her routine daily activities and with the medical clinical findings and the course of her medical treatment. Id. at 9. In addition, he noted that there was no evidence that Strongson’s condition was worse after she was terminated than before; the nature of her pain complaints migrated from one location to another; trigger points were not identified to support her claimed fibromyalgia; tests did not support her claimed rheumatological disorders; and her residual functional capacity was such that she had been able to help remodel her own home. Id. Finally, the ALJ found that Strongson, who was living with her boyfriend and was receiving alimony, was lacking in her motivation to return to the work force. Id. at 10.
We conclude that the ALJ’s determination of Strongson’s RFC incorporated the relevant medical evidence and that his credibility analysis took into account all
*1073
appropriate factors. Likewise, his hypothetical question included all the impairments he found to be credible.
See Piepgras,
The judgment is affirmed.
