Planning theory- and evidence-based behavior change interventions: a conceptual review of the intervention mapping protocol

Abstract This paper discusses the Intervention Mapping (IM) protocol for planning theory- and evidence-based behavior change interventions. IM has been developed in the field of health promotion in 1998 and has mostly been applied in that field, but applications in other fields are emerging. IM can be used for any intervention that involves changing behavior. The paper discusses the protocol and its basic issues and presents in-depth examples of its use in- and outside the health promotion field: Empowerment, return to work, safety interventions, implementation, energy conservation, and academic performance. IM is characterized by three perspectives: a social ecological approach, participation of all stakeholders, and the use of theories and evidence. Through a series of six iterative steps - from needs assessment to implementation and evaluation - which are each broken down into specific tasks, correct application of the protocol is meant to produce behavior change interventions that fit into the local context and that have the best chances of effectiveness. IM helps intervention planners develop the best possible interventions targeting health behaviors, but also targeting behaviors related to other societal issues, such as environmental concerns, safety and discrimination.

Determination of the probable date of delivery using vaginal cytology as an index.

70 normal pregnant females were used for the study, 47 of whom had vaginal cytological follow-up from week 32 till the first stage of labour. 23 additional patients had vaginal smears made in the first stage of labour. The combined intermediate cell value was used as an index of impending labour with values at week 38 being 90.35 +/- 0.0863, week 39 being 89.41 +/- 0.1934, week 40 being 81.25 +/- 0.0558 and at labour being 78.75 +/- 0.0995. The primigravidae showed a stepwise, gradual decrease in mean intermediate cell value from week 38 onwards, while the multigravidae showed a drop only at week 40. From this study, it has been shown, that it is possible to predict labour. It was also evident that there is a difference in reactivity of a primigravida versus multigravida to decreases in circulating progesterone as gauged by intermediate cell counts.
