The aim of the current umbrella review and meta-analysis was to evaluate the methodological rigor of existing meta-analyses on cognitive-behavioral treatment (CBT) for gambling harm. The Cochrane Database of Systematic Reviews, PsycINFO, and PubMed were searched for meta-analyses of CBT for gambling harm among individuals aged 18 years and older. The search yielded five meta-analyses that met inclusion criteria, representing 56 unique studies and 5389 participants. The methodological rigor for one meta-analyses was rated high, two were moderate, and two were critically low. Including only moderate- to high-quality meta-analyses, a robust variance estimation meta-analysis indicated that CBT significantly reduced gambling disorder severity (g = −0.91), gambling frequency (g = −0.52), and gambling intensity (g = −0.32) relative to minimal and no treatment control at posttreatment, suggesting 65%–82% of participants receiving CBT will show greater reductions in these outcomes than minimal or no treatment controls. Overall, there is strong evidence for CBT in reducing gambling harm and gambling behavior, and this evidence provides individuals, clinicians, managed care companies, and policymakers with clear recommendations about treatment selection.

当前的总体审查和荟萃分析的目的是评估现有针对赌博危害的认知行为治疗（CBT）荟萃分析的方法学严谨性。在 Cochrane 系统评价数据库、PsycINFO 和 PubMed 中搜索了 CBT 对 18 岁及以上个人赌博危害的荟萃分析。搜索产生了五项符合纳入标准的荟萃分析，代表了 56 项独特的研究和 5389 名参与者。一项荟萃分析的方法严谨性被评为高，两项为中等，两项为极低。仅包括中等到高质量的荟萃分析，稳健的方差估计荟萃分析表明，CBT 显着降低了赌博障碍的严重程度 ( g = -0.91)、赌博频率 ( g = -0.52) 和赌博强度 ( g = - 0.32）相对于治疗后的最低限度和无治疗控制，这表明接受 CBT 的参与者中 65%–82% 的这些结果将比最低限度或无治疗对照显示出更大的减少。总体而言，有强有力的证据表明 CBT 可以减少赌博危害和赌博行为，并且这些证据为个人、临床医生、管理式医疗公司和政策制定者提供了有关治疗选择的明确建议。
