Physical Activity and Stages of Change: A Longitudinal Test in Types 1 and 2 Diabetes Samples

Structural equation model of psychological constructs of transtheoretical model, motives for physical activity, and amount of physical activity among people with type 2 diabetes mellitus in Malaysia

BACKGROUND

This study aimed determine the structural relationship between psychological constructs of the transtheoretical model (TTM; processes of change, decisional balance, and exercise self-efficacy), motives for physical activity (PA), and amount of PA among Malaysians with type 2 diabetes mellitus (T2DM).

METHOD

All participants were recruited from the Hospital Universiti Sains Malaysia using a cross-sectional study design with purposive) sampling method. A total of 331 participants were recruited for the present study. Before participation in the study, they were informed that participation in the study was totally voluntary. Those who agreed to participate voluntarily were required to complete the self-administered questionnaire set, which included the processes of change, decisional balance, exercise self-efficacy, physical activity and leisure motivation, and international physical activity questionnaires. Data analysis of structural equation modeling was performed using Mplus 8.

RESULTS

From the 331 participants, most of whom were male (52%) and Malay (89.4%), with a mean age of 62.6 years (standard deviation = 10.29). The final structural equation model fit the data well based on several fit indices [Root Mean Square Error of Approximation (RMSEA) = 0.059, Comparative Fit Index (CFI) = 0.953, Tucker-Lewis Index (TLI) = 0.925, Standardized Root Mean Square Residual (SRMR) = 0.031]. A total of 16 significant path relationships linked between the TTM, motives for PA, and amount of PA.

CONCLUSION

The pros of decisional balance, others' expectations, and psychological condition were constructs that directly affected PA, whereas the other constructs had a significant indirect relationship with the amount of PA. A positive mindset is crucial in deciding a behavioral change toward an active lifestyle in people with T2DM.

Updated Integrated Framework for Making Clinical Decisions Across the Lifespan and Health Conditions

The updated Integrated Framework for Clinical Decision Making responds to changes in evidence, policy, and practice since the publication of the first version in 2008. The original framework was proposed for persons with neurological health conditions, whereas the revised framework applies to persons with any health condition across the lifespan. In addition, the revised framework (1) updates patient-centered concepts with shared clinical decision-making; (2) frames the episode of care around the patient's goals for participation; (3) explicitly describes the role of movement science; (4) reconciles movement science and International Classification of Function language, illustrating the importance of each perspective to patient care; (5) provides a process for movement analysis of tasks; and (6) integrates the movement system into patient management. Two cases are used to illustrate the application of the framework: (1) a 45-year-old male bus driver with low back pain whose goals for the episode of care are to return to work and recreational basketball; and (2) a 65-year-old female librarian with a fall history whose goals for the episode of care are to return to work and reduce future falls. The framework is proposed as a tool for physical therapist education and to guide clinical practice for all health conditions across the lifespan.

Multiple Unhealthy Behaviors Share Equivalent Profiles of Readiness for Change in Patients with Type 2 Diabetes

Few studies have considered more than one behavior, despite the tendency towards multiple behaviors, and there are none that have focused on a Latino population. We determined the concurrence of four unhealthy behaviors related to glycemic control and identified common cognitive factors at advanced stages of readiness for change in patients with type 2 diabetes treated in primary care. A cross-sectional study was carried out during August–December 2018 in northeastern Mexico. We consecutively included patients between 20 and 70 years who were without medical contraindication, physical impediment against exercise, pregnancy and edentulism, among other selection criteria (n = 407). Stages of behavior were measured according to the Transtheoretical Model. Pros, cons, self-efficacy, susceptibility, and severity data were collected by interview. Statistical analysis consisted of descriptive statistics and multiple logistic regression. A total of 36.7% exhibited more than one unhealthy behavior in precontemplation or contemplation (no interest or some interest in changing consumption of refined sugars and saturated fats, exercise, or oral hygiene behavior). Cons (p < 0.05) and self-efficacy (p < 0.001) were common to all four unhealthy behaviors, independent of potential confounders. Studies like ours facilitate the recognition of individuals with multiple unhealthy behaviors who share equivalent profiles of readiness for change before implementing public health programs.

The Processes of Change Scale: A Confirmatory Study of the Malay Language Version

Background

Processes of change (POC) comprise one of the psychological constructs in the Transtheoretical Model. The objective of this study is to test the validity and reliability of the Malay version of the POC scale among university students by using a confirmatory approach.

Method

A cross-sectional study design with a convenience sampling method using a self-administered questionnaire was carried out. University undergraduate students were approached to fill in the questionnaire, which consisted of demographic information and a POC scale. The POC scale consisted of 30 items and two main factors (i.e., cognitive and behavioural). The POC scale was translated into the Malay language using a standard procedure of forward and backward translation. Confirmatory factor analysis (CFA) was performed, and composite reliability was computed using Mplus version 8.

Results

A total of 620 respondents with a mean age of 20 years (standard deviation = 1.15) completed the questionnaire. Most of the participants were female (74.7%) and Malay (78.2%). The initial CFA model of the POC scale did not exhibit fit based on several fit indices (comparative fit index (CFI) = 0.880, Tucker Lewis index (TLI) = 0.867, standardised root mean square residual (SRMR) = 0.075 and root mean square error of approximation (RMSEA) = 0.058). Several re-specifications of the model were conducted and the modification included adding correlation between the items' residuals. The final model for the Malay version of the POC scale showed acceptable values of model fit indices (CFI = 0.922, TLI = 0.911, SRMR = 0.064 and RMSEA = 0.048). The composite reliability of both the cognitive and behavioural processes was acceptable at 0.856 and 0.752, respectively.

Conclusion

The final model presented acceptable values of the goodness of fit indices, indicating that the scale is fit and acceptable to be adopted for future study.

Revisiting Effective Communication Between Patients and Physicians: Cross-Sectional Questionnaire Study Comparing Text-Based Electronic Versus Face-to-Face Communication

Background

Research has shown that text-based communication via telemedicine will continue to be a mode of communication that patients and physicians use in the future. However, very few studies have examined patients’ perspectives regarding the increased use of text-based communication versus face-to-face (FtF) communication.

Objective

This study aimed to understand and compare the potential differences in patients’ perceptions of communication effectiveness with their physicians through different modes of communication.

Methods

We conducted a web-based survey of 345 patients to explore the impact of different channels on effective communication and perceived health behavior and outcomes. We tested the impact of patients’ perceived communication and media effectiveness on their self-efficacy, communication satisfaction, and perceived health outcomes, separately for text-based information technology (IT)–mediated communication and FtF communication. Furthermore, we conducted a group comparison to identify significant differences across these 2 groups.

Results

We found no significant differences between patients’ perceptions of effective communication using either IT-mediated communication or FtF communication with their physicians. However, we found significant differences in patients’ perception of media effectiveness: patients perceived FtF communication to be a more favorable medium (P=.02). Interestingly, we found no significant difference in terms of benefits (P=.09) and success (P=.08) of IT-mediated communication versus FtF communication.

Conclusions

The results of this study imply that patients can achieve the same level of communication effectiveness with their physicians using IT-mediated communication as they would in comparable FtF interactions, but patients view FtF communication to be a more favorable medium than IT-mediated communication.

Determinants of Readiness for Adopting Healthy Lifestyle Behaviors Among Indigenous Adolescents with Type 2 Diabetes in Manitoba, Canada: A Cross-Sectional Study

OBJECTIVE

The aim of this study was to determine whether the readiness for adopting healthy lifestyle behaviors was associated with mental health and comorbid conditions in youth with T2D.

METHODS

A cross-sectional comparison of various measures of mental health (distress, stress, resilience) and comorbid conditions (glycated hemoglobin, adiposity, hypertension) was conducted within a cohort of indigenous youth with T2D living in Canada, stratified according to their readiness to adopt healthy lifestyle behaviors based on Prochaska's transtheoretical model.

RESULTS

Within the entire cohort (n = 162), only 14% were considered ready to adopt all healthy lifestyle behaviors. The readiness to adopt all lifestyle behaviors was associated with higher positive mental health (47 vs. 39 units; P < 0.05) and sense of mastery (40 vs. 37 units; P < 0.05), lower perceived stress (27 vs. 29 units; P < 0.05) and distress (8 vs. 10 units; P < 0.05), and better glycemic control (HbA1c: 8.4 ± 2.6% vs. 9.7 ± 2.8%; P < 0.05) compared with youth who were not ready to adopt all lifestyle behaviors.

CONCLUSIONS

The readiness for adopting healthy lifestyle behaviors is low among adolescents with T2D. Being ready to adopt healthy lifestyle behaviors is associated with better mental health and glycemic control.

Randomized Trial of a Lifestyle Physical Activity Intervention for Breast Cancer Survivors: Effects on Transtheoretical Model Variables

This study examined whether a physical activity intervention affects transtheoretical model (TTM) variables that facilitate exercise adoption in breast cancer survivors. Sixty sedentary breast cancer survivors were randomized to a 6-month lifestyle physical activity intervention or standard care. TTM variables that have been shown to facilitate exercise adoption and progress through the stages of change, including self-efficacy, decisional balance, and processes of change, were measured at baseline, 3 months, and 6 months. Differences in TTM variables between groups were tested using repeated measures analysis of variance. The intervention group had significantly higher self-efficacy ( F = 9.55, p = .003) and perceived significantly fewer cons of exercise ( F = 5.416, p = .025) at 3 and 6 months compared with the standard care group. Self-liberation, counterconditioning, and reinforcement management processes of change increased significantly from baseline to 6 months in the intervention group, and self-efficacy and reinforcement management were significantly associated with improvement in stage of change. The stage-based physical activity intervention increased use of select processes of change, improved self-efficacy, decreased perceptions of the cons of exercise, and helped participants advance in stage of change. These results point to the importance of using a theory-based approach in interventions to increase physical activity in cancer survivors.

Prediction of Physical Activity Level Using Processes of Change From the Transtheoretical Model: Experiential, Behavioral, or an Interaction Effect?

Purpose:

The purpose of the present study was to compare prediction of physical activity (PA) by experiential or behavioral processes of change (POCs) or an interaction between both types of processes.

Design:

A cross-sectional study.

Setting:

This study was conducted using an online questionnaire.

Participants:

A total of 394 participants (244 women, 150 men), with a mean age of 35.12 ± 12.04 years and a mean body mass index of 22.97 ± 4.25 kg/m2 were included.

Measures:

Participants completed the Processes of Change, Stages of Change questionnaires, and the International Physical Activity Questionnaire to evaluate self-reported PA level (total, vigorous, and moderate PA).

Analysis:

Hierarchical multiple regression models were used to test the prediction of PA level.

Results:

For both total PA (β = .261; P < .001) and vigorous PA (β = .297; P < .001), only behavioral POCs were a significant predictor. Regarding moderate PA, only the interaction between experiential and behavioral POCs was a significant predictor (β = .123; P = .017).

Conclusion:

Our results provide confirmation that behavioral processes are most prominent in PA behavior. Nevertheless, it is of interest to note that the interaction between experiential and behavioral POCs was the only element predicting moderate PA level. Experiential processes were not associated with PA level.

Experiential or behavioral processes: which one is prominent in physical activity? Examining the processes of change 1 year after an intervention of therapeutic education among adults with obesity

OBJECTIVE

Although physical activity (PA) is essential, most obese people will not engage in its practice. The transtheoretical model (TTM) and its processes of change (POC) contribute to the understanding of behavior change regarding PA. The present study aimed to test how POC are associated with a progression through the stages of change (SOC) and whether they predict BMI change.

METHODS

Interventional study. A total of 134 subjects participated in an education program, were called at 1 year and 62 of them provided follow-up data. Participants completed the SOC and POC questionnaires at baseline, at 1 year and were classified according to their SOC progression.

RESULTS

Participants who progressed through SOC lost more weight (p<0.001). Significant interactions were found for three out of five POC (p<0.05). Progression through SOC was associated with an increased use of POC. Weight loss was predicted by two behavioral POC.

CONCLUSION

Results support the previous cross-sectional studies showing that physically active people use more frequently POC.

PRACTICE IMPLICATIONS

The present findings support the development of TTM-grounded behavioral interventions targeted to obese patients. Identifying methods to promote POC use to improve adherence to weight guidelines may lead to improved clinical outcomes and quality of life.

Self-as-Doer for Diabetes: Development and Validation of a Diabetes-Specific Measure of Doer Identification

Background: The purpose of this study was to develop and validate a scale to measure the level of self-care behavior “doer identity” in persons with diabetes. Methods: Persons with diabetes (N = 355) completed questionnaires assessing self-as-doer identity and other related constructs. Principle components and parallel analyses and tests of reliability and validity were performed. Results: A 7 factor solution explained 55.24% of the total variance on behaviors. Cronbach’s alpha was .93 for the overall scale. Extracted components moderately correlated with one another and theoretically similar constructs. Self-as-doer identity significantly predicted all self-care behaviors (except for blood glucose monitoring) and glycemic control over and above related variables for persons with type 1 diabetes. Self-as-doer identity also predicted diet behaviors for persons with type 2 diabetes. Conclusions: Evidence for a reliable and valid factor structure of the Self-as-doer-Diabetes measure was demonstrated.

Changes in social-cognitive variables are associated with stage transitions in physical activity

When it comes to the adoption or maintenance of physical activity, individuals can be placed along a continuum or into stages of change. The Health Action Process Approach proposes three such stages: non-intentional, intentional and actional. Intraindividual differences are reflected by stage transitions: either progression or regression. The present study examines social-cognitive factors of stage transitions: outcome expectancies, self-efficacy and planning. In an online study on physical activity, 660 adults completed questionnaires at baseline and approximately 3 weeks later. Social-cognitive factors were converted into standardized residual change scores to account for changes in outcome expectancies, self-efficacy and planning within the observation period. Discriminant function analyses revealed stage-specific patterns: progression out of non-intentional stage was associated with self-efficacy increases. Out of intentional stage, regression was correlated with decreases in planning, whereas progression was linked to increases in self-efficacy and planning. Regression from action stage was associated with decreases in self-efficacy. Physical activity promotion should focus on improving self-efficacy for non-intending, intending and acting individuals, whereas planning interventions are recommended for intending individuals. Interventions may be more effective by considering specific mechanisms instead of providing generic interventions for all individuals at different stages.
