The Transtheoretical Model of Behavior Change and Smokers in Southern Appalachia

Macnee, Carol L., McCabe, Susan 01 January 2004 (has links)
Background: The southern Appalachian states show a high prevalence of smoking, with associated high rates of both heart disease and cancer, yet cultural differences raise questions concerning the applicability of the most frequently used model for smoking cessation, the transtheoretical model, for smokers from this region of the country. Objective: To identify, by examining the applicability of the transtheoretical model for southern Appalachian smokers, the percentage of individuals in each of the five stages of change, the use of the processes of change from the transtheoretical model, and the scores on recognized predictors of smoking cessation including the temptation to smoke, the perceived barriers to cessation, the pros and cons of smoking, and nicotine dependence. Methods: This population-based, descriptive, cross-sectional study used a random sample of 3,800 telephone numbers, which were called up to eight times. The 659 smokers or former smokers who agreed to participate were mailed a written questionnaire consisting of six well-established scales that measure constructs from the transtheoretical model. The final sample consisted of 357 usable questionnaires. Results: The distribution of smokers in northeastern Tennessee differed from national samples across the first three stages of change, with 56% in precontemplation, as compared with previous findings of 40% in national samples. The subjects' scores for the pros of smoking were similar across the stages of change in this sample, and although the scores for the cons differed significantly across the stages in the sample, post hoc analysis indicated that the only significant change occurred between precontemplation and contemplation. The scores for temptation to smoke did not differ significantly across the stages of change in this sample. Discussion: Smokers from Appalachian Tennessee differ from smokers in other parts of the United States, and these findings raise questions about the applicability of the transtheoretical model for this population.

RELATIONSHIP BETWEEN STAGES OF CHANGE AND SNACKING HABITS OF MIDDLE INCOME CAUCASIAN ADOLESCENTS AT-RISK FOR TYPE 2 DIABETES

Pierce, Sarah 01 August 2011 (has links)
The prevalence of overweight and obesity in adolescents has increased dramatically over the past few decades. This increase is associated with a higher risk of developing Type 2 Diabetes Mellitus (T2DM). The "R.U.A. Healthy Kid?" program was created to target modifiable risk factors related to development of T2DM. This study specifically focuses on the influence of snacking habits. Researchers have documented an increase in snacking occasions and preference for low-nutrient snacks among adolescents. Many adolescent diabetes prevention programs target dietary behaviors, but none have used the Stages of Change as a theoretical framework to promote behavior change. The purpose of this study was to determine the impact of a three month community-based intervention on snack consumption and snacking habits of adolescents with risk factors for T2DM. Additionally, it explored the use of the Stages of Change model to understand how the intervention impacted adolescents' movement through the stages, and if reported stage was related to reported snack consumption and snacking habits. At completion of the study, the majority of participants reported forward progress in stages of change, indicating they were actively making changes in regards to high-nutrient (healthy) snacking. There was also a decrease in low-nutrient (unhealthy) snack consumption, and a significant improvement in overall snacking score. Participants reported several factors influenced their snack choice including hunger, taste, and availability. These findings are important to the development of appropriate programs to encourage healthy dietary behaviors at a young age.

Improving Occupational Safety & Health Interventions: A Comparison of Safety Self-Efficacy & Safety Stages of Change

Pettinger, Charles Blakley 23 May 2000 (has links)
For people aged 44 and under, the primary cause of loss of life in the U.S. is not due to heart disease or cancer, but to something as common as injuries (U. S. Bureau of Labor Statistics, 1998). As such, injuries kill an average of 142,000 Americans and require an estimated 62.5 billion dollars in medical attention each year (U. S. Bureau of Labor Statistics, 1998). This is close to three people dying and over 170 people sustaining a disabling injury every 10 minutes (National Safety Council, 1999). Every year more than 80,000 Americans are permanently disabled as a result of injury to the brain or spinal cord. Thus, unintentional injury represents a serious public health concern, and a theory-driven community, school, and organizational injury prevention technology is needed to improve the health and safety of individuals. / Ph.

Tailoring Messages within the Stages of Change

Hampton, Brandy M. 13 December 2002 (has links)
Tailored communications have been effective in increasing both recall and readership of health information. However, there is no clear evidence that tailoring is necessary or beneficial in creating behavior change. There are many possible sources for the inconsistencies in the empirical literature. This current research explores possible approaches to increase the effectiveness of message tailoring by incorporating components from the four main conceptual structures found in the literature. In the first study, the Stages of Change Model was used to segment the sample into four distinct groups (precontemplative, contemplative, action, and maintenance). The behavioral determinants for respondents in each group were then identified. The differences between the precontemplative and contemplative segment suggest that an affective message will be more effective in changing intention for precontemplative respondents and a cognitive message will be more effective for the respondents in the contemplative segment. In a second study, an experimental study was conducted to test these alternative approaches. Results show that the proposed approaches did influence males as expected. However, females did not behave in the manner expected. Possible explanations for the differences between gender, such as behavior salience and information processing styles, are discussed. Overall, support is found for the use of tailoring messages to create behavior change. / Master of Science

The Effect of Web-Based Support as an Adjunct to a Self-Help Smoking Cessation Program

Johs-Artisensi, Jennifer Lynn 08 1900 (has links)
For the past quarter century, the public has been educated and warned about the dangers of smoking, and both smokers and health researchers have been in search of cost-effective, smoking cessation programs that will lead to long-term cessation. This study used a randomized experimental design to investigate the effectiveness of adding Web-based support materials to a nationally sponsored self-help smoking intervention. There was no significant increase in abstinence rates nor progression through the stages of change by those participants who had access to the Web site. However, there were some overall significant trends that suggested these self-help interventions were successful at decreasing daily rates of smoking and nicotine dependency, as well as tended to encourage repeated quit attempts. Although Web-based supports did not appear to increase the effectiveness of the nationally sponsored self-help intervention, this study demonstrated overall 12 week follow-up abstinence rates of 30-32%--greater than what might be expected, given average success rates of other self-help interventions. This study also supports the notion that women may face additional barriers to smoking cessation. Limitations and implications for future research are discussed.

The Transtheoretical Model of Behaviour Change and Possible Selves in Criminal Offenders

Martin, Krystle Karine 17 December 2012 (has links)
In order to assist people in making positive changes of problematic behaviour it is necessary to examine how people change and what factors influence the process. Criminal offenders represent a group of individuals who often have difficulty desisting from problematic behaviour and continue to engage in illegal activity. Offenders in provincial correctional institutions were administered questionnaires to determine stage of change and processes utilized as outlined in the Transtheoretical Model (TTM) of change (Prochaska & DiClemente, 1984). Additionally, offenders were asked about their visions of the future using the Possible Selves (PSs) Model (Markus & Nurius, 1986). Taken together, this study looked at the contribution of the PSs Model to our understanding of the TTM, which has been criticized in recent years as lacking therapeutic significance for treatment providers as they guide individuals through the change process. More specifically, this study compares chronic criminals with first time offenders on psychological variables such as readiness for change, vision of possible selves, and hope for the future, as well as on legal variables such as risk for recidivism and institutional behaviour. The results indicate that most offenders acknowledged their behaviour as problematic and some even reported they were actively taking steps to change; however, chronic offenders admitted having less hope than first time offenders. Interestingly, both groups rated similarly on the dimensions of PSs. The outcomes would suggest that research efforts to incorporate other complimentary theories of change into the TTM, like the PSs model, may be helpful for understanding the process of change. While it seems these models may not be useful for predicting institutional behaviour, the data perhaps demonstrates the complexity of criminal behaviour and speaks to the necessity of further research in this population.

Applying an unfolding model to the stages and processes of change

Beever, Rob 02 January 2008
The purpose of this study was to utilize the graded unfolding model (GUM) (Roberts, 1995; Roberts & Laughlin, 1996) to examine the interaction between the stages of change (SOC) and the processes of change (POC) for smoking cessation (SC). Although an abundance of research has examined the transtheoretical model (TTM) and SC, the POC remains one of the least investigated dimensions of the TTM. Only one study has applied an item response theory model, the GUM, to the examination of the SOC and POC (Noel, 1999). This study attempted to replicate and extend the findings of Noel (1999) and provides additional external validity evidence for the SOC and the POC for SC.<p>The TTM posits that people undergoing change will use different processes and strategies as they proceed through the SOC and that each POC appears to reach peak use at different stages. Thus, the POC appear to follow an inverse-U-shaped pattern (Noel, 1999).<p>Responses to the SOC and 40-item POC for SC were collected from young adults. Analysis of the data using the GGUM (Roberts, 2000) demonstrated the applicability of the GUM and provides additional external validity of the POC for SC. More specifically, six POC were ordered as expected according to results of longitudinal studies. Four POC were found to be out of order, however, this could be due to sample characteristics or reduced validity of items (due to smoking law changes, some items may no longer be valid). Helping Relationships and Stimulus Control appeared together out of order. This finding replicates Noel (1999) and further research is needed to examine the ordering of these POC. The GUM was also found to fit the POC data better than other item response theory models.
