ABSTRACT
As illustrated throughout this volume, an arsenal of behavior change techniques is available (along with empirical validation) to increase desired work practices and decrease undesired work practices. Chapter 10 by Beth Sulzer-Azaroff, Kathleen Blake McCann, and Todd Harris, in particular, illustrates the wealth of behavior change technology available for the domain of occupational health and safety. Geller and colleagues (1990) introduced a system for categorizing behavior change interventions according to their relative cost-effectiveness (see also Geller, 1998). Interventions are categorized into multiple tiers or levels, each tier defined by its intrusiveness and cost-effectiveness. At the top of the "multiple intervention hierarchy" (i.e., Level 1), the interventions are least intrusive and target the maximum number of individuals for the least cost per individual. At this level, intervention techniques (e.g., behavioral prompting through signs, billboards, and public service announcements) are designed to have maximum large-scale appeal with minimal personal contact between target individuals and intervention agents. Geller and colleagues (1990) hypothesized
that those individuals uninfluenced by initial exposure to these types of interventions (i.e., Level 1) will be uninfluenced by repeated exposures to interventions at the same level of cost-effectiveness. These individuals require a more intrusive and costly (i.e., higher level) intervention.
