We examined the extent to which program integrity (i.e., the degree to which programs were implemented as planned) was verified and promoted in evaluations of primary and early secondary prevention programs published between 1980 and 1994. Only 39 of 162 outcome studies featured specified procedures for the documentation of fidelity. Of these, only 13 considered variations in integrity in analyzing the effects of the program. Lowered adherence to protocol was often associated with poorer outcome. There was mixed evidence of dosage effects. The omission of integrity data, particularly measures of adherence, may compromise the internal validity of outcome studies in the prevention literature. We do not view procedures for integrity verification as inconsistent with the adaptation of interventions to the needs of receiving communities.
我们考察了在1980年至1994年间发表的针对一级和早期二级预防项目的评估中，项目完整性（即项目按计划实施的程度）得到验证和促进的程度。在162项结果研究中，只有39项具有记录保真度的特定程序。其中，只有13项在分析项目效果时考虑了完整性的差异。较低的方案依从性往往与较差的结果相关。关于剂量效应的证据不一。完整性数据的缺失，尤其是依从性测量的缺失，可能会损害预防文献中结果研究的内部效度。我们认为完整性验证程序与根据接受社区的需求调整干预措施并不矛盾。
