To present common language for defining adherence of infrequent yet repeated health behaviors.
We illustrate methodological and conceptual issues using human papillomavirus (HPV) vaccination and screening mammography study data as examples.
Adherence rates of infrequent, repeated behaviors varied widely depending on how adherence was defined and measured. We advocate use of 3 standard definitions of adherence: initiation of behavior (initiation), adherence to most recent opportunity (on-schedule), and timely adherence across multiple opportunities (maintenance or completion).
The proposed framework has cross-cutting implications for research and practice. Standardizing adherence metrics may facilitate comparisons across studies of health behaviors practiced at infrequent yet repeated intervals.
提出用于定义不频繁但重复出现的健康行为依从性的通用语言。
我们以人乳头瘤病毒（HPV）疫苗接种和乳腺钼靶筛查研究数据为例，阐述方法学和概念性问题。
不频繁、重复行为的依从率因依从性的定义和测量方式不同而有很大差异。我们主张使用依从性的3种标准定义：行为起始（起始）、遵循最近一次机会（按时）以及在多个机会中及时依从（维持或完成）。
所提出的框架对研究和实践具有交叉影响。标准化依从性指标可能有助于比较间隔不频繁但重复出现的健康行为的各项研究。
