Predictors of Vaping Behavior Change in Young Adults Using the Transtheoretical Model: A Multi-Country Study

Predictors of Adolescents' Transition Through the Stages of Change for Quitting E-Cigarettes: Findings From the Population Assessment of Tobacco and Health Study

PURPOSE

To identify predictive factors associated with US adolescents' transition through the stages of change for potentially quitting e-cigarettes using the Trans-theoretical model of behavior change.

DESIGN

Prospective cohort study.

SETTING

United States.

SUBJECTS

We utilized data from adolescents (12-17 years) in Wave 3 of the Population Assessment of Tobacco and Health study who used e-cigarettes exclusively over the past 30 days (n = 177) and were followed up with in Wave 4.

MEASURES

Outcome variables were 3 transition categories: those who remained stagnant, those who progressed, and those who regressed in their stage of quitting e-cigarettes. Predictor variables were socio-demographics, e-cigarette harm perception, e-cigarette use at home or by important people, social norms, e-cigarette and anti-tobacco advertisements, and e-cigarette health warnings.

ANALYSIS

Weighted-adjusted multinomial regression analysis was performed to determine the association between predictor and outcome variables.

RESULTS

From Wave 3 to Wave 4, 19% of adolescents remained stagnant; 73.3% progressed; and 7.7% regressed. Adolescents were less likely to progress in their stage of change if they perceived nicotine in e-cigarettes to be "not at all/slightly harmful" (AOR = .26 [95% CI: .25, .27], P < .001); reported important people's use of e-cigarettes (AOR = .18 [95% CI: .05, .65, P = .009); and "rarely" noticed e-cigarette health warnings (AOR = .28 [95% CI: .08, .98, P = .054).

CONCLUSION

Intervention efforts must target specific predictive factors that may help adolescents quit e-cigarettes.

Development of transtheoretical model measures for assessing decisional balance and temptation to vape

Introduction: Vaping is common among young adults in the United States. The Transtheoretical Model (TTM) has demonstrated success in smoking cessation efforts; however, it has not been comprehensively applied to vaping cessation, and core TTM vaping measures have not been developed. Method: A cross-sectional survey including measures of stage of change (SOC), temptation to vape, and decisional balance (DCBL) was disseminated (n = 459). Items were adapted from TTM smoking scales. The sample was split for exploratory and confirmatory factor analyses (EFA/CFA). Analyses of variance assessed relationships between constructs and SOC. Results: EFA/CFA resulted in one Temptation scale (CFI = .95; α = .87) and two DCBL scales (CFI = .91; Pros α = .72; Cons α = .72). Temptation to vape and Pros of vaping decreased significantly across SOC, while Cons increased significantly. Conclusions: TTM vaping measures for two key TTM constructs were developed utilizing a college sample. Results suggest that the developed measures map well onto the TTM framework.

Effectiveness of Trans-Theoretical Model-Based Health Education Intervention in the Promotion of Lifestyle Changes among Adults with Metabolic Syndrome: A Randomized Controlled Trial

Background

Evidence revealed that, 60% of deaths in the underdeveloped nations are linked to adoption of unhealthy lifestyles. The Trans-theoretical Model (TTM) has been considered a useful interventional approach in smoking cessation, drug addiction and weight control. However, its effectiveness in improving changes in dietary pattern, physical activity and alcohol consumption has not been reported.

Purpose

The study aimed at evaluating the effectiveness of the TTM-based health education intervention in the promotion of lifestyle changes among adults with metabolic syndrome.

Methods

This was an experimental design where 352 participants with metabolic syndrome were allocated to intervention and control groups. The participants were randomly assigned to receive either standard CVD care or a TTM stage-based lifestyle modification intervention for 12-months. Lifestyle patterns were assessed at baseline and endpoint. The mean difference of the subtotal TTM concept scores between pre and post intervention was evaluated using paired t-test. The chi-square test of independence was used to detect between group differences in the categorical data.

Results

Most of the participants were in the pre-action stage of change for their dietary intake patterns and physical activity habits at the baseline assessment with no difference between the groups. The intervention group's total level of change toward adopting a healthy lifestyle was markedly (p < 0.001) improved than the control group at the endpoint. The mean scores for the intervention group's stage of change, self-efficacy, and pros and cons of decisional balance all improved significantly (p < 0.001) from the baseline. The mean scores for the control group's pros and cons of decisional balance and stage of change also considerably (p < 0.05) improved from baseline to the endpoint.

Conclusion

The TTM- based health education intervention was effective in improving the participants' lifestyles that includes diet and physical activity. Health care providers, particularly nurses should implement TTM staged-matched educational intervention for individuals who are at risk for cardiovascular diseases.

Pregnancy Desirability and Motivational Readiness for Postpartum Contraceptive Use: Findings from Population-Based Surveys in Eight Sub-Saharan African Countries

This study examined the associations between pregnancy intention and motivational readiness for postpartum contraceptive use. Data for this cross-sectional analysis were derived from nationally representative surveys of the Performance Monitoring and Accountability 2020 (PMA2020) project conducted in eight sub-Saharan African countries. Participants included 9488 nonpregnant women of reproductive age (15-49 years) who had given birth in the last 2 years. Weighted multinomial logistic regression analyses were performed to estimate the odds ratios (OR) and their corresponding 95% confidence intervals (CIs) of the associations of motivational readiness for contraceptive adoption categorized as precontemplation, contemplation, and post-action with pregnancy intention. After adjusting for confounding factors, the findings revealed that women in Côte d'Ivoire and Nigeria who had mistimed pregnancies had significantly higher odds of being in the contemplation vs. precontemplation stage compared to those who had intended pregnancies. Similarly, women who had unwanted pregnancies in Ethiopia were also more likely to be in the contemplation stage. Furthermore, significant differences were observed for women in Burkina Faso, Côte d'Ivoire, and Nigeria regarding the association between mistimed pregnancies and being in the post-action stage. For women who had unwanted pregnancies, this association was significant only in Nigeria. Additionally, the odds of being in the contemplation stage, compared to the post-action stage, for women who had unwanted pregnancies were significantly higher in Ethiopia and Nigeria. These results indicate that recent unintended pregnancies in specific sub-Saharan African countries may motivate women to take action to prevent future unintended pregnancies. The findings underscore the importance of tailored and context-specific approaches in family-planning programs based on the stage of motivational readiness.

Screening, brief intervention and referral to treatment (SBIRT) by nurses to college students who use electronic cigarettes

OBJECTIVE

To examine how screening, brief intervention and referral to treatment (SBIRT) influenced nurses' knowledge, attitude, responsibility and confidence when caring for college students using electronic cigarettes (EC).

PARTICIPANTS

Nurses (n = 8) in an urban university campus in the US.

METHODS

Training sessions included classroom instruction on SBIRT and EC, and practice with a standardized patient. Surveys administered pre and post training, and at conclusion. Measurement included nurse's knowledge of SBIRT and EC; and attitude, confidence and responsibility when using SBIRT. Students with past 90-day EC use were administered SBIRT by nurses and referred to health educator on request.

RESULTS

Over 6 weeks, 103 students reported EC use, 80 received SBIRT and 36 were referred to health educator. Nurses gained knowledge, supported using SBIRT, and reported that skills increased.

CONCLUSIONS

SBIRT is a motivational interviewing skill that nurses can learn to use to engage with college students who use EC.
