Contrary to the defendant’s contention, the Supreme Court did not err in permitting the prosecution to call an expert witness, a psychologist, to testify about, inter alia, intrafamily rape trauma syndrome. The testimony was properly admitted “to explain behavior of . . . victim[s] that might appear unusual or that jurors may not be expected to understand” (People v Carroll, 95 NY2d 375, 387 [2000]; see People v Rich, 78 AD3d 1200, 1202 [2010]). The expert “spoke about victims in general and never opined that the defendant committed the crimes, that the victim[s] w[ere] sexually abused, or that the victim[s’] specific actions and behavior were consistent with abuse” (People v Rich, 78 AD3d at 1202; see People v Carroll, 95 NY2d at 387; People v Taylor, 75 NY2d 277, 292-293 [1990]).
The Supreme Court also did not err in granting the prosecutor’s application to preclude the defendant from questioning one of the complainants about an entry in her diary indicating that a classmate had sexually abused her. The defendant did not make a showing that the circumstances or manner of the assault described in the diary “were such as to suggest a pattern casting substantial doubt on the validity of the charges made by the victim in this instance or were such as otherwise to indicate a significant probative relation to such charges” (People v Mandel, 48 NY2d 952, 953 [1979]; cf. People v Hunter, 11 NY3d 1, 6 [2008]). Moreover, there is no indication in the record that the complainant reported the incident described in the diary to anyone or confirmed that it occurred {see People v Gunther, 67 AD3d 1477, 1478 [2009]).
The defendant’s contention that the Supreme Court erred in failing to give a missing witness charge is unpreserved for appellate review {see CPL 470.05 [2]; People v Hernandez, 74 AD3d 839, 840 [2010]; People v Jacobs, 65 AD3d 594, 596 [2009]) and, in any event, is without merit {see People v Gonzalez, 68 NY2d 424, 427 [1986]; People v Rodriguez, 77 AD3d 975, 976 [2010]).
The sentence imposed was not excessive (see People v Suitte, 90 AD2d 80 [1982]). Rivera, J.E, Covello, Florio and Lott, JJ., concur.
