过程评价是评价健康促进干预措施影响的一个重要组成部分，但很少进行。对9个“一天5次”项目的过程评价结果进行了概述。过程评价有助于解释一些薄弱的方面，程序的性能，过程指标偶尔下降，随着时间的推移和人口特征的变化，和一些过程的措施有关的中介变量和程序的结果。过程评价的未来发展必须包括概念的进一步发展，过程评价的更一致和更彻底的进行，适当的方法学工作，以及过程评价组成部分和程序调解人和结果之间的关系的评估。在这一领域的进一步发展，承诺细化了解如何和为什么干预措施实现其效果，如何最好地进行干预方案，以最大限度地提高效果，并提高内部和外部的有效性的研究。
Process evaluation is an important, but infrequently conducted, component of evaluating the impact of health promotion interventions. The process evaluation results from the nine 5-a-Day projects were overviewed. Process evaluation helped explain some of the weaker aspects of program performance, process indicators occasionally declined over time and varied by demographic characteristics, and some process measures were related to mediating variables and program outcomes. Future development of process evaluation must include further development of concepts, more consistent and thorough conduct of process evaluation, appropriate methodological work, and assessment of the relations among the process evaluation components and the program mediators and outcomes. Further development in this area promises refinement in understanding how and why interventions achieve their effects, how best to conduct intervention programs to maximize effects, and enhancement of the internal and external validity of the studies.
