In-person psychotherapy (IPP) has a long and storied past, but technology advances have ushered in a new era of video-delivered psychotherapy (VDP). In this meta-analysis, pre-post changes within VDP were evaluated as were outcome differences between VDP versus IPP or other comparison groups. A literature search identified k = 56 within-group studies (N = 1681 participants) and 47 between-group studies (N = 3564). The pre-post effect size of VDP was large and highly significant, g = +0.99 95% CI [0.67–0.31]. VDP was significantly better in outcome than wait list controls (g = 0.77) but negligible in difference from IPP. Within-groups heterogeneity of effect sizes was reduced after subgrouping studies by treatment target, of which anxiety, depression, and posttraumatic stress disorder (PTSD) (each with k > 5) had effect sizes nearing 1.00. Disaggregating within-groups studies by therapy type, the effect size was 1.34 for CBT and 0.66 for non-CBT. Adjusted for possible publication bias, the overall effect size of VDP within groups was g = 0.54. In conclusion, substantial and significant improvement occurs from pre- to post-phases of VDP, this in turn differing negligibly from IPP treatment outcome. The VDP improvement is most pronounced when CBT is used, and when anxiety, depression, or PTSD are targeted, and it remains strong though attenuated by publication bias. Clinically, therapy is no less efficacious when delivered via videoconferencing than in-person, with efficacy being most pronounced in CBT for affective disorders. Live psychotherapy by video emerges not only as a popular and convenient choice but also one that is now upheld by meta-analytic evidence.

通过视频与面对面的现场心理治疗：疗效及其与治疗类型和目标关系的荟萃分析

面对面心理治疗 (IPP) 有着悠久而传奇的历史，但技术进步已经开启了视频心理治疗 (VDP) 的新时代。在这项荟萃分析中，评估了 VDP 内的前后变化以及 VDP 与 IPP 或其他比较组之间的结果差异。文献检索确定了k  = 56 项组内研究（N  = 1681 名参与者）和 47 项组间研究（N  = 3564）。VDP 的前后效应大小很大且非常显着，g  = +0.99 95% CI [0.67–0.31]。VDP 的结果明显优于候补名单控制 ( g = 0.77)，但与 IPP 的差异可以忽略不计。在按治疗目标对研究进行亚组研究后，组内效应大小的异质性降低，其中焦虑、抑郁和创伤后应激障碍 (PTSD)（每个k  > 5）的效应大小接近 1.00。按治疗类型分解组内研究，CBT 的效应大小为 1.34，非 CBT 的效应大小为 0.66。调整可能的发表偏倚后，组内 VDP 的总体效应大小为g = 0.54。总之，从 VDP 的前阶段到后阶段发生了实质性和显着的改善，这反过来与 IPP 治疗结果的差异可以忽略不计。当使用 CBT 以及针对焦虑、抑郁或 PTSD 时，VDP 的改善最为明显，并且尽管因发表偏倚而减弱，但仍保持强劲。在临床上，通过视频会议进行治疗的效果不亚于面对面，在 CBT 中对情感障碍的疗效最为明显。通过视频进行的现场心理治疗不仅成为一种流行且方便的选择，而且现在已得到元分析证据的支持。
