In appeal No. 1, petitioner mother appeals from an order that, inter alia, continued the prior visitation schedule with respect to the parties’ children. In appeal No. 2, the mother appeals from an order that, inter alia, dismissed her family offense petition. In appeal No. 3, the mother appeals from an order dismissing two petitions in which she alleged that the father had violated the temporary order of protection. We affirm the order in each appeal. Addressing first the order in appeal No. 3, we conclude that the mother has failed to brief any issues regarding that order, and we therefore deem those issues abandoned (see Matter of Jezekiah R.-A. [Edwin R.-E.], 78 AD3d 1550, 1551 [2010]; Ciesinski v Town of Aurora, 202 AD2d 984 [1994]).
Contrary to the mother’s contention with respect to the order in appeal No. 1, “ ‘[visitation decisions are generally left to Family Court’s sound discretion, requiring reversal only where the decision lacks a sound and substantial basis in the record’ ” (Matter of Nicole J.R. v Jason M.R., 81 AD3d 1450, 1451 [2011], lv denied 17 NY3d 701 [2011]; see Matter of Vieira v Huff, 83 AD3d 1520, 1521 [2011]; Matter of Vasquez v Barfield, 81 AD3d 1398 [2011]). Here, there was a sound and substantial basis in the record for the court’s determination to continue the prior visitation schedule inasmuch as it was based on a credibility as*1274sessment, and we generally defer to “the court’s firsthand assessment of the character and credibility of the parties” (Matter of Thayer v Thayer, 67 AD3d 1358, 1359 [2009]; see Nicole J.R., 81 AD3d at 1451; Matter of Hill v Rogers, 213 AD2d 1079 [1995]).
We reject the mother’s contention with respect to the order in appeal No. 2 that the court erred in taking sworn testimony from her before issuing a temporary order of protection (see generally Family Ct Act § 828; Matter of Ardis S. v Sanford S., 88 Misc 2d 724, 725-726 [1976]; Sobie, Practice Commentaries, McKinney’s Cons Laws of NY, Book 29A, Family Ct Act § 828, at 286). Finally, we conclude with respect to the order in appeal No. 2 that the court properly dismissed the family offense petition inasmuch as the mother failed to meet her burden of establishing by a fair preponderance of the evidence that the father committed the family offense of harassment in the second degree (see Family Ct Act § 812 [1]; § 832; Matter of Woodruff v Rogers, 50 AD3d 1571 [2008], lv denied 10 NY3d 717 [2008]; Matter of Deborah D. v Kathy D., 26 AD3d 759 [2006]). “Contrary to the further contention of the mother, the court’s assessment of the credibility of the witnesses is entitled to great weight, and the court was entitled to credit the testimony of the father over that of the mother” (Matter of Kobel v Holiday, 78 AD3d 1660 [2010]; see Matter of Danielle S. v Larry R.S., 41 AD3d 1188 [2007]).
