What are multiple intervention programs? Print E-mail

Multiple intervention programs are co-ordinated, interconnected interventions aimed at improving health by making changes to more than one level of a socio-ecological system. They’re based on the socio-ecological model of health, which recognizes that it’s the interaction between individual behaviour and social environments that shapes health. (Refer below to: Box A1 Principles of Ecological Approaches) A socio-ecological model says health is influenced at various levels of social organization: intrapersonal, interpersonal, organizational, community, and policy (McLeroy, Bibeau, Steckler, & Glanz, 1988; Merzel & D’Affletti).

Box A1: Principles of ecological approaches to changing health behaviour

  1. Multiple levels of factors influence health behaviour
  2. Multiple types of environmental influences affect health behaviour
  3. Ecological models focusing on health behaviour can be useful
  4. Multi-level interventions may be most effective
  5. Multi-level interventions are most easily implemented by multi-sectoral groups
  6. To evaluate ecological interventions, monitor implementation and change at multiple levels
  7. Political dynamics can limit ecological interventions.  (Glanz, Rimer, & Lewis, 2002)

Multiple intervention programs target at least two levels of the socio-ecological system, even if each level has only one intervention. So a MIP might aim to make changes in individual behaviour, some organizations and municipal by-laws. It’s not a multiple intervention program if there’s more than one intervention, but only at one system level; or there’s more than one target group, but only one intervention (Edwards et al., 2004).
