BACKGROUND
Personalized feedback is a promising self-help for problem gamblers. Such interventions have shown consistently positive results with other addictive behaviours, and our own pilot test of personalized normative feedback materials for gamblers yielded positive findings. The current randomized controlled trial evaluated the effectiveness, and the sustained efficacy, of the personalized feedback intervention materials for problem gamblers.
METHODOLOGY/PRINCIPAL FINDINGS: Respondents recruited by a general population telephone screener of Ontario adults included gamblers with moderate and severe gambling problems. Those who agreed to participate were randomly assigned to receive: 1) the full personalized normative feedback intervention; 2) a partial feedback that contained all the feedback information provided to those in condition 1 but without the normative feedback content (i.e., no comparisons provided to general population gambling norms); or 3) a waiting list control condition. The primary hypothesis was that problem gamblers who received the personalized normative feedback intervention would reduce their gambling more than problem gamblers who did not receive any intervention (waiting list control condition) by the six-month follow-up.
CONCLUSIONS/SIGNIFICANCE: The study found no evidence for the impact of normative personalized feedback. However, participants who received, the partial feedback (without norms) reduced the number of days they gambled compared to participants who did not receive the intervention. We concluded that personalized feedback interventions were well received and the materials may be helpful at reducing gambling. Realistically, it can be expected that the personalized feedback intervention may have a limited, short term impact on the severity of participants' problem gambling because the intervention is just a brief screener. An Internet-based version of the personalized feedback intervention tool, however, may offer an easy to access and non-threatening portal that can be used to motivate participants to seek further help online or in person.

背景
个性化反馈是一种有前途的问题赌徒自助方法。这种干预措施在其他成瘾行为中显示出一致的积极结果，我们自己对赌徒的个性化规范反馈材料的试点测试也产生了积极的结果。目前的随机对照试验评估了个性化反馈干预材料对问题赌徒的有效性和持续效果。
方法/主要发现：通过安大略省成年人的一般人群电话筛选器招募的受访者包括有中度和重度赌博问题的赌徒。那些同意参与的人被随机分配接受以下三种干预方式之一：1）完整的个性化规范反馈干预；2）部分反馈，其中包含提供给条件 1 中的所有反馈信息，但没有规范反馈内容（即，没有与一般人群赌博规范进行比较）；或 3）候补名单对照组。主要假设是，接受个性化规范反馈干预的问题赌徒在六个月的随访中，其赌博行为会比未接受任何干预的问题赌徒（候补名单对照组）减少。
结论/意义：该研究没有发现规范个性化反馈的影响证据。然而，与未接受干预的参与者相比，接受部分反馈（无规范）的参与者减少了他们赌博的天数。我们得出的结论是，个性化反馈干预措施受到了很好的接受，并且这些材料可能有助于减少赌博。实际上，可以预期个性化反馈干预可能对参与者问题赌博的严重程度产生有限的短期影响，因为干预只是一个简短的筛选器。然而，基于互联网的个性化反馈干预工具可能提供一个易于访问且不会构成威胁的门户，可以用来激励参与者在线或亲自寻求进一步的帮助。
