以人口为基础的健康研究是监测人口健康和物质使用等相关因素的关键资源，但可靠的推断可能会以各种方式受到影响。无反应和自然减员是主要的方法学问题，如果参与研究和留在研究中的人与不参与研究的人有系统地不同，这些问题会降低力量，并可能阻碍研究结果的推广。在这一期的SPPE中，McCabe等人。对2001-2002年全国酒精及相关疾病流行病学调查的参与者进行了研究，比较了第一波中不同物质使用模式的参与者在第二波中的消耗情况。讨论了不同后续行动的影响以及解决选择性参与的进一步可能性。
Population-based health studies are critical resources for monitoring population health and related factors such as substance use, but reliable inference can be compromised in various ways. Non-response and attrition are major methodological problems which reduce power and can hamper the generalizability of findings if individuals who participate and who remain in a study differ systematically from those who do not. In this issue of SPPE, McCabe et al. studied participants of the 2001–2002 National Epidemiologic Survey on Alcohol and Related Conditions, comparing attrition in Wave 2 across participants with different patterns of substance use at Wave 1. The implications of differential follow-up and further possibilities for addressing selective participation are discussed.
