A growing literature supports the efficacy of cognitive-behavioral therapies, motivational interventions, and personalized feedback to treat problem and disordered gambling. However, there is currently debate as to how much treatment is necessary. Some studies indicate that attending a greater number of sessions is related to enhanced therapeutic outcomes, while other studies indicate that one session produces equivalent therapeutic outcomes to multiple sessions. To contribute to this debate, meta-analysis was used to examine the relation between dose and outcome in studies of cognitive-behavioral, motivational, and personalized feedback interventions (both individual and group treatment formats were included). Fourteen studies of randomized controlled trials representing 1,203 participants across 19 treatment-control comparisons were identified. The intended treatment dose (i.e., the number of sessions prescribed to participants) across the 14 studies ranged from 1 to 30 sessions. Of the 10 studies reporting the received treatment dose (i.e., the number of sessions that participants attended), the weighted mean dose was 6.8 sessions (SD = 2.7). Both intended treatment dose and received treatment dose were positively related to outcome at posttreatment-as the number of sessions increased, so too did the magnitude of the between group effect size. There were an insufficient number of studies reporting outcome at long-term follow up to evaluate the relation between intended dose, received dose, and outcome. Discussion centers on several areas for future research on psychological treatments for problem and disordered gambling. Specific recommendations are made for researchers and practicing clinicians.

更好吗?对问题和无序赌博进行面对面心理治疗的剂量和功效的荟萃分析。

越来越多的文献支持认知行为疗法,动机干预和个性化反馈来治疗问题和无序赌博的功效。但是,目前关于需要多少治疗的争论。一些研究表明,参加更多的疗程与提高治疗效果有关,而其他研究表明,一个疗程产生与多个疗程相同的治疗效果。为了促进这场辩论,在认知行为,动机和个性化反馈干预措施(包括个体和小组治疗形式)的研究中,采用荟萃分析来检查剂量与结果之间的关系。确定了代表19个治疗对照比较中的1,203名参与者的14项随机对照试验研究。在14项研究中,预期的治疗剂量(即,规定给参与者的疗程数)为1至30疗程。在报告接受治疗剂量(即参加者参加的疗程数)的10项研究中,加权平均剂量为6.8疗程(SD = 2.7)。预期的治疗剂量和接受的治疗剂量均与治疗后的结果呈正相关-随着疗程数的增加,组间效应量的大小也随之增加。尚缺乏足够的研究报告长期随访结果以评估预期剂量,接受剂量和结果之间的关系。讨论集中在几个领域,以便对问题和无序赌博的心理治疗进行进一步的研究。针对研究人员和临床医生提出了具体建议。(PsycINFO数据库记录(c)2020 APA,保留所有权利)。
