Using Multitheory Model to Predict Low-Salt Intake Among Nigerian Adults Living With Hypertension

Predicting Flossing through the Application of the Multi-Theory Model (MTM) of Health Behavior Change among Minority Adolescents in the United States

Adolescents from minority groups are particularly susceptible to poor oral hygiene behaviors, including lack of daily flossing. This cross-sectional study aimed to conduct an exploratory behavioral research to identify evidence-based (theory-based) approaches to promote flossing behavior among African American/Black and Latinx/Hispanic (minority) adolescents. A 39-item psychometrically valid web-based questionnaire was used to collect responses from a nationwide sample of minority adolescents aged 10-17 years residing in the United States. The data were analyzed using bivariate and multivariate statistical methods. Of 520 minority adolescents (260 African American/Black and 260 Latinx/Hispanic adolescents), the proportion of flossing was nearly equally split in the sample. A significantly higher proportion of minority adolescents who were flossing had access to floss as opposed to those who were not flossing (86.8% vs. 69.8%, p < 0.001). A significantly higher proportion of minority adolescents who were not flossing did not visit the dentist over the past year as opposed to those who floss (25.2% vs. 14.7%, p < 0.001). Among the participants who were not flossing, gender, grade level, instruction in school regarding flossing, and multi-theory model (MTM) of health behavior change constructs were the significant predictors (p < 0.001) of initiating and sustaining flossing. The findings of this study will serve as baseline data for developing and evaluating effective evidence-based interventions using the MTM.

Can the Multi-Theory Model (MTM) of Health Behavior Change Explain the Intent for People to Practice Meditation?

Meditation is gaining popularity as adjuvant therapy for many chronic ailments, mental well-being, and spiritual growth. Behavioral theories have been underutilized in understanding meditation behavior. This study aimed to test if a fourth-generation multi-theory model (MTM) could explain the intent for starting and maintaining meditation behavior in a sample of US adults. A face and content valid 48-item instrument based on MTM was administered in a cross-sectional design through an online survey (n = 330). Internal consistency (Cronbach's alpha > 0.70) and construct validation using structural equation modeling of the subscales were all acceptable. Hierarchical multiple regression revealed that, after controlling for demographic covariates, the MTM constructs of participatory dialogue (β  =  0.153; P  =  .002) and behavioral confidence (β  =  0.479; P < .001) were statistically significant in predicting intent for starting meditation behavior and accounted for 32.9% of the variance. Furthermore, after controlling for demographic covariates, the MTM constructs of emotional transformation (β  =  0.390; P < .001) and changes in the social environment (β  =  0.395; P < .001) were statistically significant and accounted for 52.9% of the variance in the intent for maintaining meditation behavior. Based on this study, it can be concluded that MTM offers a pragmatic framework to design, implement, and evaluate evidence-based (theory-based) meditation behavior change interventions.

Explaining Screen-Time Behavior Among Preschoolers in Northern India Using Multi Theory Model: A Parental Cross-Sectional Survey

BACKGROUND

Screen-time (ST) is the time spent on digital media. The American Academy of Pediatrics recommends the daily ST of less than an hour for preschoolers. However, increased ST among preschoolers is becoming a public health concern.

OBJECTIVE

This study assessed the multi-theory model (MTM)'s applicability in explaining the ST behavior change among preschoolers through parents.

METHODS

A quota sample of 72 parents was drawn from Northern India. Data were analyzed using multiple regression.

RESULTS

Behavioral confidence (p < 0.001) and changes in the physical environment (p < 0.001) significantly predicted the initiation of reducing ST. The sustenance of limiting ST was significantly predicted by the emotional transformation (p < 0.001), practice for change (p < 0.001), and changes in the social environment (p = 0.001).

CONCLUSIONS

The study highlights the usability of the MTM model in designing and testing interventions for parents to limit ST among their children.

Utility of Multi-Theory Model (MTM) to Explain the Intention for PAP Adherence in Newly Diagnosed Sleep Apnea Patients

PURPOSE

The objective of this study was to assess the utility of a fourth-generation multi-theory model (MTM) in explaining the intention for initiation and sustenance of PAP adherence among newly diagnosed sleep apnea patients.

PATIENTS AND METHODS

For this cross-sectional study, data were collected at a private sleep center located in the Southeastern United States. A total of 138 newly diagnosed patients with sleep apnea who had been prescribed PAP therapy completed a valid and reliable 41-item MTM instrument. Stepwise multiple regression modeling was conducted to assess MTM based explanatory variables of PAP adherence in this study sample.

RESULTS

MTM constructs namely participatory dialogue (β = 0.17, p = 0.014), behavioral confidence (β = 0.48, p < 0.001), and changes in the physical environment (β = 0.26, p = 0.001) were statistically significant predictors of the intention for initiation of PAP therapy and accounted for 53.5% of the variance. Emotional transformation (β = 0.57, p < 0.001), changes in the social environment (β = 0.16, p = 0.016), and practice for change (β = 0.16, p = 0.047) were statistically significant predictors of the intention for sustenance of PAP therapy and accounted for 60.6% of the variance.

CONCLUSION

The MTM was found to be a promising theoretical model in explaining the intention for initiation and sustenance of PAP therapy.

Using the Multi-Theory Model (MTM) of Health Behavior Change to Explain Intentional Outdoor Nature Contact Behavior among College Students

Nature contact is an emerging health behavior and is defined as the interaction between human beings and animals, plants, natural scenic views, or outdoor activities. Studies have shown that exposure to the outdoors (as a means of contact with nature) reduces perceived stress and promotes health and wellbeing among varying populations in many settings. To date, however, there are few studies exploring the impact of nature contact among college students, especially in the United States. In addition, the determinants of nature contact behavior have not adequately been explored using behavioral theories. The purpose of this study was to use the multi-theory model (MTM) of health behavior change, a contemporary fourth-generation behavioral theory in explaining intentional outdoor nature contact behavior among college students. Using a cross-sectional design, 401 students completed the validated survey based on MTM. Of these, 281 met the inclusion criteria. The mean score for perceived stress based on the Perceived Stress Scale (PSS-10) in the sample was 21.60 (7.08) units, with a possible minimum and maximum scores ranging from 0 to 40 units. Constructs of behavioral confidence (standardized coefficient = 0.591, p < 0.001) and changes in the physical environment (standardized coefficient = 0.271, p < 0.001) from MTM accounted for 57.5% of the variance in the initiation for intentional outdoor nature contact behavior. All the three constructs of MTM—namely, emotional transformation (standardized coefficient = 0.173, p = 0.021), practice for change (standardized coefficient = 0.317, p < 0.001), and changes in the social environment (standardized coefficient = 0.204, p = 0.002)—were statistically significant and contributed substantively toward the variance (31.0%) in sustenance. MTM provides a useful and pragmatic framework for designing interventions to promote intentional nature contact behavior among college students.

Efficacy testing of the SAVOR (Sisters Adding Fruits and Vegetables for Optimal Results) intervention among African American women: A randomized controlled trial

Background: In the United States, only about 15% of individuals meet daily fruit intake recommendations of 2 cups per day and only 10% meet the vegetable intake recommendations of3 cups per day. African American women are a high-risk group. In this study, a fourth-generation multi-theory model (MTM) of health behavior change was used to design and evaluate a SistersAdding Fruits and Vegetables for Optimal Results (SAVOR) intervention for AA women.

Methods: The study utilized a randomized controlled trial (RCT) with measurements taken at pretest, posttest (after the three-week intervention) and follow-up (at the end of eight weeks).SAVOR (n=26) was compared to an equivalent knowledge-based intervention (n=28). Process evaluation was done for program fidelity and satisfaction. A validated 38-item self-reported questionnaire was used to measure changes in MTM constructs and past 24-hour consumption of fruits and vegetables.

Results: The SAVOR intervention resulted in improvement of mean consumption of fruits and vegetables in the experimental group from pre-test (2.78) to posttest (4.77) to recommended levels at follow-up (5.04) while in the comparison group they remained at around 3 (P<0.0001)Statistically significant changes (P<0.05) were noted for all MTM constructs except for participatory dialogue.

Conclusion: The SAVOR intervention was found to be efficacious and established the robustness of MTM. SAVOR can be replicated for future effectiveness trials.
