The proposal was designed to establish the causal factors, also known as determinants, which would produce a larger effect on influencing behaviors compared to alternative theories (Dusseldorp et al, 2014). The TTI includes three different streams of influence: cultural or environmental, social or interpersonal, and intrapersonal, and also three levels of determinants: ultimate, distal, and proximal (Edberg, 2015). The study set out to focus on the distal and ultimate determinants, these two factors are more relevant to determine the rooted causes of behaviors, since both have a wider effect on various behaviors (Dusseldorp et al, 2014). The final goal was to answer research questions surrounding three behavior clusters: health, alcohol, and delinquency (Dusseldorp et al, 2014). The research questions were meant to locate the relationship between the health clusters and how they are related to the TTI (Dusseldorp et al, 2014). The researchers performed a cross sectional study on a stratified random sample of participants age 19-40 from the 2005-2006 Risk Behavior Survey in Dutch (Dusseldorp et al, 2014). The original sample size was more narrowed; it was stratified into three different age groups. It was then combined into one large group, because each age group would display similar factors that affect behaviors (Dusseldorp et al, 2014). Oversampling was used on two groups, those with disadvantaged backgrounds, and ethnic minorities (Dusseldorp et al, 2014). Different data collecting methods were used: computer interviews, online survey, and face to face. Multiple categories were set for scoring within each factor, for example, within the alcohol factor, the scoring was based on number of glasses consumed per day, and how many days within a week consuming alcohol, etc. and similar for the health and delinquency factors. The study then used various statistical
