摘要
在过去十年中,临床研究,特别是自杀研究中越来越多地使用密集时间取样方法,如生态瞬间评估(EMA)。虽然生态瞬间评估可以捕捉个体内部的动态过程,但重复评估会增加参与者的负担,可能导致依从性较低。本研究旨在揭示可能预测瞬间提示(即提示到提示)完成情况的研究水平和心理变量,包括自杀意念(SI)。我们综合了三项研究心理健康困难的 EMA 研究的数据(N = 103;10656 次提示;7144 次完成),使用多层次模型和机器学习来确定我们能多好地预测提示到提示的完成情况,以及哪些变量是最重要的。在完成提示到提示的过程中,两个最重要的变量是距上次提示的时间和学习时间。心理变量几乎没有增加预测的有效性;同样,特质水平的 SI 对提示到提示完成的影响也很小。我们的研究表明,在 EMA 研究中,研究层面的特征可用于解释提示到提示的依从率,突出了开发适应性评估表以提高依从率的潜力。
Examining missingness at the momentary level in clinical research using ecological momentary assessment: Implications for suicide research
The use of intensive time sampling methods, such as ecological momentary assessment (EMA), has increased in clinical, and specifically suicide, research during the past decade. While EMA can capture dynamic intraindividual processes, repeated assessments increase participant burden, potentially resulting in low compliance. This study aimed to shed light on study-level and psychological variables, including suicidal ideation (SI), that may predict momentary prompt (i.e., prompt-to-prompt) completion. We combined data from three EMA studies examining mental health difficulties (N = 103; 10,656 prompts; 7144 completed), using multilevel models and machine learning to determine how well we can predict prompt-to-prompt completion and which variables are most important. The two most important variables in prompt-to-prompt completion were hours since the last prompt and time in study. Psychological variables added little predictive validity; similarly, trait-level SI demonstrated a small effect on prompt-to-prompt completion. Our study showed how study-level characteristics can be used to explain prompt-to-prompt compliance rates in EMA research, highlighting the potential for developing adaptive assessment schedules to improve compliance.

Founded in 1945, the Journal of Clinical Psychology is a peer-reviewed forum devoted to research, assessment, and practice. Published eight times a year, the Journal includes research studies; articles on contemporary professional issues, single case research; brief reports (including dissertations in brief); notes from the field; and news and notes. In addition to papers on psychopathology, psychodiagnostics, and the psychotherapeutic process, the journal welcomes articles focusing on psychotherapy effectiveness research, psychological assessment and treatment matching, clinical outcomes, clinical health psychology, and behavioral medicine.
