What is the test for reviewable abuse of the hearsay rule?

"A trial court's exercise of discretion in admitting or excluding evidence is reviewable for abuse. [Citation.] Abuse may be found if the trial court exercised its discretion in an arbitrary, capricious, or patently absurd manner, but reversal of the ensuing judgment is appropriate only if the error has resulted in a manifest miscarriage of justice. [Citations.]" (People v. Coddington (2000) 23 Cal.4th 529, 587-588, overruled on other grounds in Price v. Superior Court (2001) 25 Cal.4th 1046, 1069, fn. 13.) "Evidence of a statement offered against a party is not made inadmissible by the hearsay rule if the statement is one of which the party, with knowledge of the content thereof, has by words or other conduct manifested his adoption or his belief in its truth." (Evid. Code 1221.)
