    Rita F. COGBILL, Appellant, v. Michael J. ASTRUE, Commissioner, Social Security Administration, Appellee.
    No. 11-1309.
    United States Court of Appeals, Eighth Circuit.
    Submitted: July 22, 2011.
    Filed: Aug. 1, 2011.
    Rita F. Cogbill, Carl Junction, MO, pro se.
    Mark S. Naggi, Spec. Asst. U.S. Atty., Kansas City, MO (Beth Phillips, U.S. Atty., Kristi A. Schmidt, Chief Counsel, Region VII, Soc. Sec. Admin., Kansas City, MO, of counsel, on the brief), for appellee.
    Before LOKEN, BYE, and COLLOTON, Circuit Judges.
   PER CURIAM.

Rita F. Cogbill appeals the district court’s order affirming the denial of disability insurance benefits. Upon careful review of the record, see Gates v. Astrue, 627 F.3d 1080, 1082 (8th Cir.2010) (standard of review), we conclude that the administrative law judge (ALJ) gave several valid reasons for his adverse credibility determination, and thus it is entitled to deference, see Halverson v. Astrue, 600 F.3d 922, 932 (8th Cir.2010); that the ALJ was not required to schedule a consultative mental examination, see id. at 933 (ALJ is required to order medical examinations and tests only if medical records before him provide insufficient medical evidence to determine if claimant is disabled); and that the vocational expert’s testimony in response to the ALJ’s properly formulated hypothetical constituted substantial evidence, see Robson v. Astrue, 526 F.3d 389, 392 (8th Cir.2008). Accordingly, we affirm. 
      
      . The Honorable Robert E. Larsen, United States Magistrate Judge for the Western District of Missouri, to whom the case was referred for final disposition by consent of the parties pursuant to 28 U.S.C. § 636(c).
     
      
      . We decline to consider some of Cogbill’s arguments as she cites no supporting authority or her assertions are not supported by the record.
