纵向研究的一个主要问题是由于损耗而产生的偏差，特别是在患有精神障碍的患者中。与研究参与相关的因素进行了调查，作为一个更大的研究合作（STRATA）的一部分。在479名合格参与者中，只有50名（10.4%）成功随访。本研究调查了研究参与是否因基线特征而异。结果表明，没有参加的人更有可能报告酒精使用障碍，而那些有反应的人更有可能接受全日制教育的时间更长，并且是白色种族。参与并没有不同的诊断，症状，GAF，发病年龄或抑郁症。
A major problem with longitudinal studies is the bias generated due to attrition, particularly apparent amongst patients suffering from psychotic disorders. Factors associated with study-participation were investigated as part of a larger research collaboration (STRATA). Out of 479 eligible participants, only 50 (10,4%) were successfully followed up. The present study investigated whether study participation differed depending on baseline characteristics. Results indicated that individuals who did not participate were more likely to report an alcohol use disorder while those who did respond were more likely to have been in full-time education for longer and be of white ethnicity. Participation did not differ depending on diagnosis, symptoms, GAF, age of onset or depression.
