We trust that you have been thinking about the concepts from the previous modules and trying to apply them in situations in your own setting. In module four, we offer another perspective on understanding health related behavior. This is the process approach. When, we first examined the dimensions of behavior that might make it easier or more difficult to adopt a certain action. We know that that behavior is not like a light switch that you can turn off and on. This is because of things like frequency, complexity, cultural congruence, and the linkages associated with performing the behavior. Now, we're taking this idea a step further and showing that there is a pathway toward adopting a new behavior. And subsequently, reinforcing its continued performance. In the module on theoretical models, we talked about likelihood of taking action, or intentions to act. Here we'll be looking at the steps that bring a person toward greater likelihood of acting or not. First, we must recognize that many people may not realize the changes necessary, or helpful, or possible. They may not have heard about protecting their water pots from mosquitoes. Or may not think that mosquitoes are a major problem in their household. At some point, people might become aware that mosquitoes are a problem, and start to seek information from friends, neighbors, the health department, on how to prevent mosquito breeding In their home environment. If they evaluate the options that they learned about and decided worth their time, effort, and money. They may start planning action and eventually implemented plan. And hopefully maintained it, in order to prevent dengue and Zika from spreading in their environment. We must also consider that people can relapse from performing the new behavior. Maybe the covering for their water drum gets torn or lost. They may not be immediately willing or able to get a new one. Or they may simply have been tired of constantly covering their potted drum and leave the cover off sometimes.. Thus they may start the process of change all over again in order to start healthy behaviors. Such process models have been termed non-theoretical, but that is not really the case. When planning behavior change, it is important to look at which step or stage a person is at, and find out why they're at that stage? We can look back at the force field. What would drive them forward? Or what would restrain or push them back? And look for the factors from our theoretical models to explain why people are stuck at a certain stage, or maybe willing to move forward? Again, we thank you for listening to our lectures. And we hope you are now developing your own behavioral diagnosis toolkit. And are better able to understand how local explanatory models can be used to construct and test theoretical models which in turn can help us understand how and why people move along the pathway to behavior change.
