Instructions: Decide which of the four models might be a good fit for each of the following public health examples. A counseling program for teen alcoholism wants to find out what treatment techniques work best for the varying degrees of readiness among its clients. A researcher is interested in understanding how the availability or lack of availability of condoms can play a role in risky sex behaviors among teenage girls in order to design an intervention.
Sleep restriction is a prevalent issue for adolescents and has been associated with negative cognitive, emotional, and physical health e. The aim of this randomized controlled trial is to evaluate the effectiveness of Motivating Teens to Sleep More program — a sleep promotion program with embedded sleep education that combines three approaches: motivational interviewing style, tailoring activities, and stage-based intervention — as compared to a sleep education only control in motivating adolescents to go to bed earlier leading to prolonged sleep duration. The Motivating Teens to Sleep More study will be conducted with adolescents at a Montreal high school.
A cross-sectional study was carried out among students who took part in the co-curricular program. Co-curricular program includes activities that take place outside of the regular lectures or tutorials in the University. Students recruited through purposive sampling were informed that their participation was entirely voluntarily. Those interested completed the self-administered questionnaire, which consisted of the decisional balance, processes of change, self-efficacy, stages of change scales, and Godin leisure-time exercise questionnaire.
Abstract : To predict demographic, psychosocial, and behavioral variables specific to each stage by determining the stages of change of dietary behaviors of adolescents within the framework of TTM and thus to guide for interventions make adolescents ready for next stage of change. A descriptive, cross-sectional design was used in the study. Separate multivariate logistic regression models were created to determine the readiness of adolescents to make changes in dietary behaviors.
The transtheoretical model of behavior change is an integrative theory of therapy that assesses an individual's readiness to act on a new healthier behavior, and provides strategies, or processes of change to guide the individual. The transtheoretical model is also known by the abbreviation " TTM "  and sometimes by the term " stages of change ",   although this latter term is a synecdoche since the stages of change are only one part of the model along with processes of change, levels of change, etc. It has been called "arguably the dominant model of health behaviour change, having received unprecedented research attention, yet it has simultaneously attracted criticism".
Traditionally, changing AOD use was viewed as a single event rather than a process. This often involved only one possible outcome: total cessation or abstinence. This view does not take into account the small steps towards cessation that a person might make and the achievement that those smaller steps might represent such as reducing the number of cigarettes smoked in a week.
The Transtheoretical Model also called the Stages of Change Modeldeveloped by Prochaska and DiClemente in the late s, evolved through studies examining the experiences of smokers who quit on their own with those requiring further treatment to understand why some people were capable of quitting on their own. It was determined that people quit smoking if they were ready to do so. Thus, the Transtheoretical Model TTM focuses on the decision-making of the individual and is a model of intentional change.
