MEMORANDUM AND ORDER
SAM A. CROW, Senior District Judge.
This is an action reviewing the final decision of the Commissioner of Social Security denying the plaintiff supplemental security income payments. The matter has been fully briefed by the parties.
I. General legal standards
The court's standard of review is set forth in 42 U.S.C. § 405(g), which provides that "the findings of the Commissioner as to any fact, if supported by substantial evidence, shall be conclusive." The court should review the Commissioner's decision to determine only whether the decision was supported by substantial evidence and whether the Commissioner applied the correct legal standards. Glenn v. Shalala , 21 F.3d 983, 984 (10th Cir. 1994). Substantial evidence requires more than a scintilla, but less than a preponderance, and is satisfied by such evidence that a reasonable mind might accept to support the conclusion. The determination of whether substantial evidence supports the Commissioner's decision is not simply a quantitative exercise, for evidence is not substantial if it is overwhelmed by other evidence or if it really constitutes mere conclusion. Ray v. Bowen , 865 F.2d 222, 224 (10th Cir. 1989). Although the court is not to reweigh the evidence, the findings of the Commissioner will not be mechanically accepted. Nor will the findings be affirmed by isolating facts and labeling them substantial evidence, as the court must scrutinize the entire record in determining whether the Commissioner's conclusions are rational. Graham v. Sullivan , 794 F.Supp. 1045, 1047 (D. Kan. 1992). The court should examine the record as a whole, including whatever in the record fairly detracts from the weight of the Commissioner's decision and, on that basis, determine if the substantiality of the evidence test has been met. Glenn , 21 F.3d at 984.
The Social Security Act provides that an individual shall be determined to be under a disability only if the claimant can establish that they have a physical or mental impairment expected to result in death or last for a continuous period of twelve months which prevents the claimant from engaging in substantial gainful activity (SGA). The claimant's physical or mental impairment or impairments must be of such severity that they are not only unable to perform their previous work but cannot, considering their age, education, and work experience, engage in any other kind of substantial gainful work which exists in the national economy. 42 U.S.C. § 423(d).
The Commissioner has established a five-step sequential evaluation process to determine disability. If at any step a finding of disability or non-disability can be made, the Commissioner will not review the claim further. At step one, the agency will find non-disability unless the claimant can show that he or she is not working at a "substantial gainful activity." At step two, the agency will find non-disability unless the claimant shows that he or she has a "severe impairment, " which is defined as any "impairment or combination of impairments which significantly limits [the claimant's] physical or mental ability to do basic work activities." At step three, the agency determines whether the impairment which enabled the claimant to survive step two is on the list of impairments presumed severe enough to render one disabled. If the claimant's impairment does not meet or equal a listed impairment, the inquiry proceeds to step four, at which the agency assesses whether the claimant can do his or her previous work; unless the claimant shows that he or she cannot perform their previous work, they are determined not to be disabled. If the claimant survives step four, the fifth and final step requires the agency to consider vocational factors (the claimant's age, education, and past work experience) and to determine whether the claimant is capable of performing other jobs existing in significant numbers in the national economy. Barnhart v. Thomas , 124 S.Ct. 376, 379-380 (2003).
The claimant bears the burden of proof through step four of the analysis. Nielson v. Sullivan , 992 F.2d 1118, 1120 (10th Cir. 1993). At step five, the burden shifts to the Commissioner to show that the claimant can perform other work that exists in the national economy. Nielson , 992 F.2d at 1120; Thompson v. Sullivan , 987 F.2d 1482, 1487 (10th Cir. 1993). The Commissioner meets this burden if the decision is supported by substantial evidence. Thompson , 987 F.2d at 1487.
Before going from step three to step four, the agency will assess the claimant's residual functional capacity (RFC). This RFC assessment is used to evaluate the claim at both step four and step five. 20 C.F.R. §§ 404.1520(a)(4), 404.1520(e, f, g); 416.920(a)(4), 416.920(e, f, g).
II. History of case
On October 8, 2010, administrative law judge (ALJ) William H. Rima issued his decision (R. at 20-30). Plaintiff alleges that she has been disabled since April 1, 2009 (R. at 20). At step one, the ALJ found that plaintiff has not engaged in substantial gainful activity since plaintiff's alleged onset date of disability (R. at 22). At step two, the ALJ found that plaintiff has the following severe impairments: bipolar disorder, posttraumatic stress syndrome (PTSD), paranoid personality disorder, and drug abuse (R. at 22). At step three, the ALJ determined that plaintiff's impairments do not meet or equal a listed impairment (R. at 23). After determining plaintiff's RFC (R. at 25), the ALJ determined at step four that plaintiff is unable to perform any past relevant work (R. at 29). At step five, the ALJ determined that plaintiff could perform other jobs that exist in significant numbers in the national economy (R. at 29-30). Therefore, the ALJ concluded that plaintiff was not disabled (R. at 30).
III. Did the ALJ err in his analysis of plaintiff's credibility?
Credibility determinations are peculiarly the province of the finder of fact, and a court will not upset such determinations when supported by substantial evidence. However, findings as to credibility should be closely and affirmatively linked to substantial evidence and not just a conclusion in the guise of findings. Kepler v. Chater , 68 F.3d 387, 391 (10th Cir. 1995). Furthermore, the ALJ cannot ignore evidence favorable to the plaintiff. Owen v. Chater , 913 F.Supp. 1413, 1420 (D. Kan. 1995).
When analyzing evidence of pain, the court does not require a formalistic factor-by-factor recitation of the evidence. So long as the ALJ sets forth the specific evidence he relies on in evaluating the claimant's credibility, the ALJ will be deemed to have satisfied the requirements set forth in Kepler. White v. Barnhart , 287 F.3d 903, 909 (10th Cir. 2002); Qualls v. Apfel , 206 F.3d 1368, 1372 (10th Cir. 2000). Furthermore, the ALJ need not discuss every relevant factor in evaluating pain testimony. Bates v. Barnhart , 222 F.Supp.2d 1252, 1260 (D. Kan. 2002). An ALJ must therefore explain and support with substantial evidence which part(s) of claimant's testimony he did not believe and why. McGoffin v. Barnhart , 288 F.3d 1248, 1254 (10th Cir. 2002). It is error for the ALJ to use standard boilerplate language which fails to set forth the specific evidence the ALJ considered in determining that a claimant's complaints were not credible. Hardman v. Barnhart , 362 F.3d 676, 679 (10th Cir. 2004). On the other hand, an ALJ's credibility determination which does not rest on mere boilerplate language, but which is linked to specific findings of fact fairly derived from the record, will be affirmed by the court. White , 287 F.3d at 909-910.
The court will not reweigh the evidence or substitute its judgment for that of the Commissioner. Hackett v. Barnhart , 395 F.3d 1168, 1173 (10th Cir. 2005); White v. Barnhart , 287 F.3d 903, 905, 908, 909 (10th Cir. 2002). Although the court will not reweigh the evidence, the conclusions reached by the ALJ must be reasonable and consistent with the evidence. See Glenn v. Shalala , 21 F.3d 983, 988 (10th Cir. 1994)(the court must affirm if, considering the evidence as a whole, there is sufficient evidence which a reasonable mind might accept as adequate to support a conclusion). The court can only review the sufficiency of the evidence. Although the evidence may support a contrary finding, the court cannot displace the agency's choice between two ...
