To explore the impact of asking for a collateral on respondent attrition and the impact of providing versus not providing a collateral on self-reported drinking.
As part of a larger trial assessing the efficacy of self-help materials for problem drinkers, respondents were randomly assigned to be asked or not asked to provide a collateral at the time of their 6-month follow-up.
While there was no significant impact of client attrition, respondents who were asked for a collateral and provided one reported higher levels of alcohol consumption at the 6-month follow-up as compared to those who were asked for a collateral but did not provide one.
Providing a collateral may have an impact on respondent's self-reported drinking. Alternate explanations for this finding are discussed.
探讨要求提供担保对受访者流失率的影响，以及提供担保与不提供担保对自我报告饮酒情况的影响。
作为一项评估自助材料对问题饮酒者疗效的大型试验的一部分，受访者在6个月随访时被随机分配是否被要求提供担保。
虽然对客户流失率没有显著影响，但被要求提供担保并提供了担保的受访者在6个月随访时报告的饮酒量高于被要求提供担保但未提供担保的受访者。
提供担保可能会对受访者自我报告的饮酒情况产生影响。讨论了这一发现的其他解释。
