Objectives: Uptake of psychosocial services during cancer treatment remains relatively low. To use these services efficiently, novel approaches - based on evidence-based theory - are needed to understand cancer patients' readiness to seek psychosocial services. Guided by the transtheoretical model (TTM), we investigated individuals' readiness to use psychosocial services by assessing decisional conflict (pros/cons) and self-efficacy, which are established as the most important constructs of predicting a specific behavior.

Cancer patients frequently experience considerable distress during diagnosis and treatment. The aims of this study were to describe the development and utilization of a psychological service for cancer patients at a community hospital-and to provide preliminary results on clinical outcomes in a "real-world" clinical setting. This program was developed collaboratively by individuals from a university-based clinical psychology doctoral program and a community hospital.

Over the past 40 years, few breakthroughs have dramatically increased the impacts of psychotherapy. There have been new and exciting therapies, but the research does not convincingly demonstrate that any recent or more established therapies produce greater impacts than 40 years ago. Seven strategies from the transtheoretical model that have produced breakthroughs in health psychology/population health are analyzed to illustrate how they can similarly generate breakthroughs in mental health outcomes.

The transtheoretical model and the stages of change are often used to adapt treatment to the individual client. The aims of this study were to review the stages of change and popular measures of change readiness in psychotherapy and to conduct a meta-analysis of the relation between readiness measures and psychotherapy outcomes. We report data from 76 studies, encompassing 25,917 patients.

Introduction: Although integrated primary care (IPC) is growing, several barriers remain. Better understanding of behavioral health professionals' (BHPs') readiness for and engagement in IPC behaviors could improve IPC research and training. This study developed measures of IPC behaviors and stage of change.

The Dietary Guidelines for Americans recommend a 20-35 percent daily intake of fat. Resisting the temptation to eat high-fat foods, in conjunction with stage of readiness to avoid these foods, has been shown to influence healthy behavior change. Data ( N = 6516) from three randomized controlled trials were pooled to examine the relationships among direct intervention effects on temptations and stage of change for limiting high-fat foods.

Background: Tobacco use remains the leading cause of preventable disease and death. Most smokers are not motivated to quit; however, most smoking cessation interventions are designed for smokers who are ready to take action.

Objectives: The aim of the present study was to describe participant engagement and satisfaction with telephonic smoking cessation coaching with a population of smokers at different stages of readiness to quit.

Purpose: Previous studies found that treatment effects can change two behaviors, but not one. This study examined baseline transtheoretical model constructs as three alternative predictors (stage of change, effort, and severity) of singular action among participants with co-occurring health behavior risks.

Design: The study examined participants at risk for three pairs of behaviors (sun and smoking; smoking and diet; and diet and sun).

This study examined longitudinal differences in use of transtheoretical model (TTM) behavior change constructs in maintainers (who reached and maintained exercise guidelines), relapsers (who reached guidelines, then regressed), and nonchangers (who did not reach guidelines). Data from two population-based TTM-tailored randomized trial intervention groups targeting exercise behavior (N = 1050) were pooled, and analyses assessed differences in TTM constructs between the three groups at baseline, 12 months, and 24 months. Findings indicated that relapsers tended to use TTM variables similarly to maintainers with the exception of self-efficacy, consciousness raising, and most behavioral processes of change, at 24 months.

This research examined dynamic transtheoretical model (TTM) constructs for dietary fat reduction. This secondary data analysis pooled three large population-based TTM-tailored school, worksite, medical, and home-based intervention studies and examined use of constructs across three groups organized by longitudinal progress (dynatypes): Maintainers, Relapsers, and Stable Non-Changers. The criteria for successful change, at the time, were that less than 30% of calories came from fat.

Background: Traditional null hypothesis significance testing suffers many limitations and is poorly adapted to theory testing.

Purpose: A proposed alternative approach, called Testing Theory-based Quantitative Predictions, uses effect size estimates and confidence intervals to directly test predictions based on theory.

Method: This paper replicates findings from previous smoking studies and extends the approach to diet and sun protection behaviors using baseline data from a Transtheoretical Model behavioral intervention (N = 5407).

Purpose: This research examined dynamic transtheoretical model (TTM) constructs for adopting sun protection practices. This secondary data analysis pooled four large population-based TTM-tailored intervention studies and examined use of constructs across three groups, organized by longitudinal progress: maintainers, relapsers, and stable non-changers.

Methods: A total of 3463 adults, in the USA, who met criteria for unsafe sun exposure at baseline received a TTM-tailored computerized intervention at baseline, 6 months, and 12 months.

Purpose: In the United States, 36% of human papillomavirus (HPV)-related cancers occur among men. HPV vaccination can substantially reduce the risk of HPV infection; however, the vast majority of men are unvaccinated. This study developed and validated transtheoretical model-based measures for HPV vaccination in young adult men.

Single occupancy vehicle (SOV) transportation is a key contributor to climate change and air pollution. Sustainable transportation (ST), commuting by any means other than SOV, could both slow climate change and enhance public health. The transtheoretical model (TTM) provides a useful framework for examining how people progress towards adopting ST.

Traditionally, the concept of health promotion has emphasized the reduction of health risk behaviors to reduce disease and impairment. Well-being research expands this focus to include positive constructs such as thriving, productivity, life-evaluation, and emotional and physical health. The objective of the present study was to examine the relationships between health risk behaviors and specific measures of individual well-being.
