that a parent has been ordered to serve a prison sentence “of such length that the child will be deprived of a normal home for a period of years.” To justify severance pursuant to § 8 — 533(B)(3), ADES must prove that a parent is unable to discharge parental responsibilities because of mental illness, mental deficiency, or chronic substance abuse and that the condition is reasonably likely to continue for a prolonged, indeterminate period. To justify severance pursuant to § 8 — 533(B)(7)(b), ADES must prove the child has been in a court-ordered, out-of-home placement for fifteen months or longer; the parent has been unable to remedy the circumstances which led to the out-of-home placement; and there is a substantial likelihood that the parent will be incapable of providing “proper and effective parental care and control in the near future.” Under the latter ground, the court is required to consider the availability of reunification services and the parent’s participation in those services. § 8 — 533(C).
¶ 3 Under any of the grounds enumerated in § 8-533(B), the court must also consider the best interests of the child. § 8-533(B); Michael J. v. Arizona Dep’t of Econ. Sec., 196 Ariz. 246, ¶ 12, 995 P.2d 682, ¶ 12 (2000); In re Maricopa County Juvenile Action No. JS-8490, 179 Ariz. 102, 107, 876 P.2d 1137, 1142 (1994). If clear and convincing evidence supports any one of the statutory grounds on which the juvenile court ordered severance, we need not address claims pertaining to the other grounds. Michael J., 196 Ariz. 246, ¶ 27, 995 P.2d 682, ¶ 27; In re Maricopa County Juvenile Action No. JS-6520, 157 Ariz. 238, 756 P.2d 335 (App.1988).
¶ 4 The standard of proof required to terminate parental rights under § 8-533(B) is clear and convincing evidence. A.R.S. § 8-537(B); see also Ariz.R.P.Juv.Ct. 66(C), 17B A.R.S.; Michael J., 196 Ariz. 246, ¶ 12, 995 P.2d 682, ¶ 12. The juvenile court, as the trier of fact in a termination proceeding, is in the best position to weigh the evidence, observe the parties, judge the credibility of witnesses, and make appropriate findings. In re Pima County Dependency Action No. 93511, 154 Ariz. 543, 546, 744 P.2d 455, 458 (App.1987). On review, therefore, we will accept the juvenile court’s findings of fact unless no reasonable evidence supports those findings, and we will affirm a severance order unless it is clearly erroneous. Michael J., 196 Ariz. 246, ¶ 20, 995 P.2d 682, ¶ 20; Jennifer B. v. Arizona Dep’t of Econ. Sec., 189 Ariz. 553, 555, 944 P.2d 68, 70 (App.1997).
¶ 5 The juvenile court in this case prepared a remarkably thorough, thirteen-page minute entry containing detailed findings of fact and conclusions of law. We have reviewed the record in its entirety and find it contains reasonable evidence to support the juvenile court’s factual findings, which include the following: Blanca and Selena are the sixth and seventh of their mother’s eight children, none of whom remains in her custody. Blanca, Selena, and four of their brothers were removed from Yolanda’s custody in March 1999, several days after she had been evicted from her residence. Yolanda admitted the allegations of a first amended dependency petition, including the allegation that her serious drug addiction rendered her unable to care for her children, six of whom were adjudicated dependent as to her on April 9, 1999. Selena and Blanca were adjudicated dependent as to their respective fathers on the same date, both fathers having likewise admitted the allegations of the petition.
¶ 6 Selena’s parents had been married for several months when she was bom on June 4,1997. Like Yolanda, Jesus was also a drug addict. In November 1997 he was sent to prison where he remains, serving a 6.5-year sentence for burglary. He testified that his earliest possible release date is in March 2003 and the latest is in January 2004. The court found his earliest possible release date to be October 2003.1 The court also found that, because Jesus is a Mexican national, he

According to Division One of this court in James S. v. Arizona Department of Economic Security, 193 Ariz. 351, ¶ 12 n. 3, 972 P.2d 684, ¶ 12 n. 3 (App.1998), instead of considering the parent’s anticipated release date, the court should instead consider the actual length of the sentence, independent of whether earlier release might be possible. See In re Maricopa County Juvenile Action No. JS-5609, 149 Ariz. 573, 575, 720 P.2d 548, 550 (App. 1986).
