The issue in this case is whether, for purposes of ORS 161.295, alcohol dependence is a “mental disease or defect” or, instead, is a “personality disorder.” The Court of Appeals held that it was a personality disorder. For reasons that this court set out at greater length in Tharp v. PSRB, 338 Or 413, 110 P3d 103 (2005), we similarly conclude that alcohol dependence is a personality disorder as that term is used in ORS 161.295(2) and that, therefore, it is not a mental disease or defect. Accordingly, we affirm the decision of the Court of Appeals.

In January 2002, a trial court found petitioner guilty except for insanity of attempted assault in the second degree, based on mental disease or defect. The trial court placed petitioner under the jurisdiction of the Psychiatric Security Review Board (board) for a maximum of five years. ORS 161.327(1). In April 2002, the board held a hearing pursuant to ORS 161.341(7)(a) to determine whether petitioner should be conditionally discharged or released.1 After such a hearing, the board must discharge the committed person if the board finds that “the person is no longer affected by a mental disease or defect, or, if so affected, no longer presents a substantial danger to others * * ORS 161.346(l)(a).

At petitioner’s hearing, the state introduced evidence from petitioner’s criminal proceeding, evaluations and tests conducted while petitioner was committed to the state hospital, and the testimony of petitioner’s treating physician at the state hospital. That evidence contained diagnoses by petitioner’s treating physician and others that petitioner was affected by an “antisocial personality disorder” and “alcohol dependence.” Neither party identified any evidence in the record that petitioner suffered from any other mental disease or defect. At the hearing, the state argued that petitioner’s alcohol dependence was a mental disease or defect, that petitioner presented a substantial danger to others, and that *451petitioner’s commitment to the state hospital and to the board’s jurisdiction should be continued. Petitioner responded that alcohol dependence was a “personality disorder” as that term is used in ORS 161.295(2) and therefore is excluded from the definition of “mental disease or defect.” Accordingly, petitioner argued that ORS 161.346(l)(a) required the board to discharge him. The board rejected petitioner’s arguments and ordered that petitioner’s commitment be continued.

Petitioner appealed, and the Court of Appeals reversed. Ashcroft v. PSRB, 192 Or App 467, 86 P3d 102 (2004). That court concluded that the record contained substantial evidence that petitioner suffers from alcohol dependence but, as noted, held that alcohol dependence is a personality disorder and, therefore, is not a mental disease or defect within the meaning of ORS 161.295(2).2 Id. at 469. We allowed the board’s petition for review.

In Tharp, this court reviewed in detail the statutes that authorize a court in a criminal proceeding to find a person guilty except for insanity because of a “mental disease or defect,” the procedures by which a court may order a person found guilty except for insanity committed to the jurisdiction of the board, and the procedures by which a person so committed may be discharged if the board determines, after a hearing, that the person is no longer affected by a mental disease of defect. 338 Or at 415-16, 420-22. Tharp then considered the meaning of the term “mental disease or defect” and the legislature’s exclusion from that term of “an abnormality manifested only by repeated criminal or otherwise antisocial conduct * * * [or] any abnormality constituting solely a personality disorder.”3 ORS 161.295(2). Id. at 420-30. After *452reviewing the text of the statute and the legislative history, this court concluded that “substance dependency5 is a “personality disorder” as that term is used in ORS 161.205(2), and therefore is not a “mental disease or defect.” Id. at 430.

This court’s decision in Tharp, including our analysis of the relevant statutes and the legislative history, demonstrates that alcohol dependence, like the drug and substance dependence that we discussed in Tharp, is a “personality disorder.” See Tharp, 338 Or at 430 (“The legislative history shows that the legislature intended to exclude personality disorders such as drug and alcohol dependency from the terms ‘mental disease5 and ‘mental defect5 as it used those terms in ORS 161.295.55). The Court of Appeals correctly so held in this case, and we therefore affirm that decision.

The decision of the Court of Appeals is affirmed. The order of the Psychiatric Security Review Board is vacated, and the case is remanded to the board for further proceedings.
