UNASSIGNED: Climate change poses one of the most pervasive threats to the planet today. Intervention is required to promote pro-environmental behaviors among individuals to curb its effects. Borrowing several constructs from the Theory of Planned Behavior, we designed and evaluated a campaign, delivered primarily through Instagram, to shift sustainability-related cognitions and behaviors among university students.
UNASSIGNED: An online survey was distributed to undergraduate students at a Northern California university and collected responses from 1,552 participants.
UNASSIGNED: Comparing students who self-reported exposure to the campaign with those who were not exposed, students who observed the campaign materials had more knowledge about (p < .001), greater perceived social norms about (p < .001), and greater intentions to perform sustainable behaviors (p < .001). There were also increases in sustainable behaviors during the campaign, compared to the previous academic term.
UNASSIGNED: Implementing campaigns inspired by behavior change theories may be one viable strategy to increase individual sustainable behaviors for climate change mitigation.

OBJECTIVE: To explore the relationship between health coaches\' responses to emotional cues/concerns and women\'s subsequent engagement with the health coaching mHealth platform.
METHODS: 24 face-to-face video-mediated initial conversations between participants and their health coaches were coded using the VR-CoDES-P method. Women with high risk of developing Gestational Diabetes Mellitus were selected from the study, based on their engagement with the smartphone health coaching platform. 12 women with very low engagement and 12 women with high engagement were identified.
RESULTS: In interactions with women with high goal engagement, coaches had significantly more counseling codes with prior other codes and no instances of non-explicit response codes that reduce space for further disclosure. Analysis showed that interactions with women with high goal engagement were more frequently met by the coach with affect-acknowledging and empathic responses prior to the counseling speech act.
CONCLUSIONS: High goal engagement among women with Gestational Diabetes Mellitus may appear to be associated with coaches facilitating the frequent use of empathy.
CONCLUSIONS: Findings can draw coaches\' attention to the impact that their counseling has on goal engagement, increasing the opportunity for intervention to be person-centered and effective.

BACKGROUND: More than half (55%) of Latina women do not meet aerobic physical activity (PA) guidelines, and frequently cite time, childcare, and transportation as barriers to PA. In addition to linguistic adaptations for this population, successful PA interventions for Latina women addressed these barriers through remote intervention delivery approaches (eg, mail, phone, or web delivery).
OBJECTIVE: We aimed to evaluate 6-month outcomes of a randomized trial comparing a Spanish-language, individually tailored, web-delivered PA intervention (original) to an enhanced version with text messages and additional features (enhanced). Further, we evaluated if increases in PA at 6 months were moderated by baseline activity status.
METHODS: In total, 195 Latina women aged 18-65 years participated in a trial comparing the efficacy of the enhanced versus original interventions at initiating PA behavior change. We examined minutes per week of accelerometer-measured PA in the enhanced versus original arms, and the proportion of each arm meeting aerobic PA guidelines (150 min/wk at 6 mo). For moderator analyses, participants were classified as inactive (0 min/wk) or low active (1-90 min/wk) at baseline, measured via the 7 Day Physical Activity Recall interview.
RESULTS: PA increased from 19.7 (SD 47.9) minutes per week at baseline to 46.9 (SD 66.2) minutes per week at 6 months in the enhanced arm versus 20.6 (SD 42.7) minutes per week to 42.9 (SD 78.2) minutes per week in the original arm (P=.78). Overall, 30% (31/103) of the enhanced group met aerobic PA guidelines at 6 months, compared to 21% (19/92) of the original group (odds ratio [OR] 1.75, 95% CI 0.87-3.55). Baseline PA (inactive vs low active) moderated treatment effects on PA. For inactive participants, there were no group differences at 6 months (b=7.1; SE 22.8; P=.75), while low-active participants increased more in enhanced than original (b=72.5; SE 27.9; P=.01). For low-active participants, 45% (46/103) of the enhanced group met PA guidelines at 6 months, versus 20% (18/92) of the original arm (OR 3.29, 95% CI 1.05-11.31). For inactive participants, there were no group differences (25/103, 24% vs n=19/92, 21% for enhanced vs original, respectively; OR 1.28, 95% CI 0.54-3.06).
CONCLUSIONS: Intervention effects were conditional on baseline PA. For low-active Latina women, the enhanced intervention was more effective at increasing PA. Additional tailored intervention enhancements may be necessary to increase PA for inactive Latina women.

Hand hygiene behavior is crucial to counter the spread of infectious diseases. However, its adoption during the early stages of the Coronavirus disease (COVID-19) pandemic showed temporal fluctuations associated with the trajectory of the pandemic (e.g. new COVID-19 infections). Such associations can confound conclusions about the effectiveness of interventions aimed at promoting hand hygiene during a pandemic. In this study, we performed a secondary analysis of a dataset from the optimization phase of Soapp, an app to promote hand hygiene during the COVID-19 pandemic. We used a longitudinal study design to test whether the associations between the pandemic trajectory and hand hygiene behavior were still present one year after the outbreak (primary outcome) and whether they impacted conclusions about the effectiveness of Soapp (secondary outcome). Participants (N = 216) were randomized to different versions of Soapp and used an electronic diary to self-report their hand hygiene behavior multiple times during the study. We considered the following indicators of the COVID-19 pandemic from the country of Switzerland in the period between March and August 2021: total cases/deaths, increases in recent new cases/deaths, new cases/deaths, and number of administered doses of vaccine. Data were analyzed using a multilevel approach. Results suggested that there were no significant associations between hand hygiene and the indicators of the pandemic trajectory. However, models including total cases/deaths impacted the conclusions about Soapp\'s effectiveness. Implications from this study are that the development and evaluation of hand hygiene interventions during a pandemic context should account for the trajectory indicators to maximize their effectiveness and control for confounding effects.
Hand hygiene is an effective behavior for decreasing the transmission of infectious diseases, including Coronavirus disease (COVID-19). During the early stages of the COVID-19 pandemic, hand hygiene was in part related to how the pandemic evolved over time (pandemic trajectory), e.g., how many people were affected or the number of deaths. We argue that such associations can confound conclusions about the effectiveness of interventions aimed at promoting hand hygiene during a pandemic. To test this hypothesis, we estimated how indicators of the pandemic trajectory influenced the evaluation of a smartphone app developed to promote hand hygiene during COVID-19. Our analysis included 216 participants who used the app for 34 days between March and August 2021 and reported their hand hygiene behavior using an electronic diary. Information on the pandemic trajectory were extracted from the World Health Organization database. Results confirmed that hand hygiene behavior increased with the use of the app when accounting for most pandemic trajectory indicators. However, this effect disappeared when accounting specifically for the total number of cases and deaths since the beginning of the pandemic. These results underline the importance of considering the pandemic trajectory when evaluating the efficacy of behavior change interventions carried out during an ongoing pandemic.

BACKGROUND: Interventions to promote physical activity among women breast cancer survivors (BCS) in low- to middle-income countries are limited. We assessed the acceptability and preliminary effectiveness of a theory-driven, group-based dance intervention for BCS delivered in Bogotá, Colombia.
METHODS: We conducted a quasi-experimental study employing a mixed-methods approach to assess the 8-week, 3 times/week group dance intervention. The effect of the intervention on participants\' physical activity levels (measured by accelerometry), motivation to engage in physical activity, and quality of life were evaluated using generalized estimating equation analysis. The qualitative method included semi-structured interviews thematically analyzed to evaluate program acceptability.
RESULTS: Sixty-four BCS were allocated to the intervention (n = 31) or the control groups (n = 33). In the intervention arm, 84% attended ≥ 60% of sessions. We found increases on average minutes of moderate-to-vigorous physical activity per day (intervention: +8.99 vs control: -3.7 min), and in ratings of motivation (intervention change score = 0.45, vs. control change score= -0.05). BCS reported improvements in perceived behavioral capabilities to be active, captured through the interviews.
CONCLUSIONS: The high attendance, behavioral changes, and successful delivery indicate the potential effectiveness, feasibility, and scalability of the intervention for BCS in Colombia.

UNASSIGNED: Combining continuous positive airway pressure with physical activity (PA) might be a promising strategy to treat obstructive sleep apnea (OSA). This article describes how intervention mapping (IM) can guide the development, content, and mechanisms of action of a mobile application to promote PA in adults with OSA.
UNASSIGNED: To develop the program, the IM approach was followed. This article presents the first three steps of IM to develop a mixed intervention (with interventionists and a digital application) aiming to: (1) assess patients\' health problems and needs in a literature review to determine their expectations and perceived facilitators and barriers to PA behavior change and thus select the determinants of behavior; (2) formulate the expected intervention outcomes and objectives to be met to achieve the overall program goals; and (3) select and implement the behavior change techniques (BCTs) to achieve the change objectives.
UNASSIGNED: The literature review identified the relevant determinants (e.g., self-efficacy, coping, planning, and habit) of PA behavior using the health action process approach and multiprocess action control. These results were used to specify the program outcomes for PA adapted to physical, psychological, and social parameters. Overall, 11 performance objectives and 30 change objectives were defined. Lastly, BCTs and practical applications were identified.
UNASSIGNED: The study provides a theoretical and methodological basis for researchers and practitioners given the current paucity of evidence-based PA interventions for adults with OSA. It addresses the lack of BCTs (framing and prompts/cue techniques) and meaningful behavioral determinants (identity and habit) in most interventions.

Excess dietary salt intake is well established as a leading cause of high blood pressure and associated cardiovascular disease, yet current salt intake in India is nearly 11 g per day, more than twice World Health Organization maximum recommended intake of 5 g per day. Although dietary survey data from India indicate that the main sources of dietary salt are salt added during cooking at home, and few salt reduction efforts have focused on interventions at the household level. As a result, there is little evidence of the effectiveness of behavior change programs to reduce salt intake at the household level. The study aims to develop and implement a community based behavioral change intervention to reduce salt intake delivered by front line community-based health volunteers; and evaluate the preliminary effectiveness, acceptability, and feasibility of delivering a salt reduction behavior change program and potential to support future scale-up. The study is a pre-post intervention design, and outcomes will be evaluated from a random sample of 1500 participants from 28 villages in two primary health centers in Siddipet, Telangana. Primary outcome is change in salt-related KAB (knowledge, attitude, and behavior) score, and secondary outcomes will be changes in salt intake measured by 24 h urinary sodium excretion and change in scores using the subscales of the COM-B (\"capability\", \"opportunity\", \"motivation\" and \"behavior\") tool. Findings will be used to inform future public health policies to support implementation of scalable community-based interventions to reduce salt intake and control hypertension, the leading-cause of death in India.

Hand hygiene is an effective behavior for preventing the spread of the respiratory disease COVID-19 and was included in public health guidelines worldwide. Behavior change interventions addressing hand hygiene have the potential to support the adherence to public health recommendations and, thereby, prevent the spread of COVID-19. However, randomized trials are largely absent during a pandemic; therefore, there is little knowledge about the most effective strategies to promote hand hygiene during an ongoing pandemic. This study addresses this gap by presenting the results of the optimization phase of a Multiphase Optimization Strategy of Soapp, a smartphone app for promoting hand hygiene in the context of the COVID-19 pandemic.
This study aimed to identify the most effective combination and sequence of 3 theory- and evidence-based intervention modules (habit, motivation, and social norms) for promoting hand hygiene. To this end, 9 versions of Soapp were developed (conditions), and 2 optimization criteria were defined: the condition with the largest increase in hand hygiene at follow-up and condition with the highest engagement, usability, and satisfaction based on quantitative and qualitative analyses.
This study was a parallel randomized trial with 9 intervention conditions defined by the combination of 2 intervention modules and their sequence. The trial was conducted from March to August 2021 with interested participants from the Swiss general population (N=232; randomized). Randomization was performed using Qualtrics (Qualtrics International Inc), and blinding was ensured. The duration of the intervention was 34 days. The primary outcome was self-reported hand hygiene at follow-up, which was assessed using an electronic diary. The secondary outcomes were user engagement, usability, and satisfaction assessed at follow-up. Nine participants were further invited to participate in semistructured exit interviews. A set of ANOVAs was performed to test the main hypotheses, whereas a thematic analysis was performed to analyze the qualitative data.
The results showed a significant increase in hand hygiene over time across all conditions. There was no interaction effect between time and intervention condition. Similarly, no between-group differences in engagement, usability, and satisfaction emerged. Seven themes (eg, \"variety and timeliness of the task load\" and \"social interaction\") were found in the thematic analysis.
The effectiveness of Soapp in promoting hand hygiene laid the foundation for the next evaluation phase of the app. More generally, the study supported the value of digital interventions in pandemic contexts. The findings showed no differential effect of intervention conditions involving different combinations and sequences of the habit, motivation, and social norms modules on hand hygiene, engagement, usability, and satisfaction. In the absence of quantitative differences, we relied on the results from the thematic analysis to select the best version of Soapp for the evaluation phase.

BACKGROUND: Regular physical activity (PA) is recommended to optimize weight and health outcomes in patients who have undergone metabolic and bariatric surgery (MBS). However, >70% of patients have low PA levels before MBS that persist after MBS. Although behavioral interventions delivered face-to-face have shown promise for increasing PA among patients who have undergone MBS, many may experience barriers, preventing enrollment into and adherence to such interventions. Delivering PA behavior change interventions via telehealth to patients who have undergone MBS may be an effective strategy to increase accessibility and reach, as well as adherence.
OBJECTIVE: This paper reports the protocol for a study that aims to assess the feasibility and acceptability of the protocol or methods and the Telehealth Bariatric Behavioral Intervention (TELE-BariACTIV). The intervention is designed to increase moderate-to-vigorous intensity PA (MVPA) in patients awaiting bariatric surgery and is guided by a multitheory approach and a patient perspective. Another objective is to estimate the effect of the TELE-BariACTIV intervention on presurgical MVPA to determine the appropriate sample size for a multicenter trial.
METHODS: This study is a multicenter trial using a repeated (ABAB\'A) single-case experimental design. The A phases are observational phases without intervention (A1=pre-MBS phase; A2=length personalized according to the MBS date; A3=7 months post-MBS phase). The B phases are interventional phases with PA counseling (B1=6 weekly pre-MBS sessions; B2=3 monthly sessions starting 3 months after MBS). The target sample size is set to 12. Participants are inactive adults awaiting sleeve gastrectomy who have access to a computer with internet and an interface with a camera. The participants are randomly allocated to a 1- or 2-week baseline period (A1). Protocol and intervention feasibility and acceptability (primary outcomes) will be assessed by recording missing data, refusal, recruitment, retention, attendance, and attrition rates, as well as via web-based acceptability questionnaires and semistructured interviews. Data collected via accelerometry (7-14 days) on 8 occasions and via questionnaires on 10 occasions will be analyzed to estimate the effect of the intervention on MVPA. Generalization measures assessing the quality of life, anxiety and depressive symptoms, and theory-based constructs (ie, motivational regulations for PA, self-efficacy to overcome barriers to PA, basic psychological needs satisfaction and frustration, PA enjoyment, and social support for PA; secondary outcomes for a future large-scale trial) will be completed via web-based questionnaires on 6-10 occasions. The institutional review board provided ethics approval for the study in June 2021.
RESULTS: Recruitment began in September 2021, and all the participants were enrolled (n=12). Data collection is expected to end in fall 2023, depending on the MBS date of the recruited participants.
CONCLUSIONS: The TELE-BariACTIV intervention has the potential for implementation across multiple settings owing to its collaborative construction that can be offered remotely.

BACKGROUND: Total hip arthroplasty is considered an efficacious procedure for relieving pain and disability, but despite that objectively measured physical activity level remains unchanged compared to pre-surgery and is still considerably lower than that of a healthy age- and sex-matched population 6-12 months post-surgery. Since there is a graded relationship between physical activity level and functional performance, increasing physical activity may enhance the outcome of the procedure. This study aims to investigate whether promotion and support of physical activity initiated 3 months after total hip arthroplasty complementary to usual rehabilitation care can increase objective measured physical activity 6 months post-surgery.
METHODS: The trial is designed as a pragmatic, parallel group, two-arm, assessor-blinded, superiority, randomized (1:1), controlled trial with post intervention follow-up 6 and 12 months after total hip arthroplasty. Home-dwelling, independent, and self-reliant patients with hip osteoarthritis are provisionally enrolled prior to surgery and re-screened about 2-3 months post-surgery to confirm eligibility. Baseline assessment is conducted 3 months post-surgery. Subsequently, patients (n=200) are randomized to either a 3-month, multimodal physical activity promotion/education intervention or control (no further attention). The intervention consists of face-to-face and telephone counselling, patient education material, pedometer, and step-counting journal. The primary outcome is objectively measured physical activity, specifically the proportion of patients that complete on average ≥8000 steps per day 6 months post-surgery. Secondary outcomes include core outcomes (i.e., physical function, pain, and patient global assessment) and health-related quality of life. Furthermore, we will explore the effect of the intervention on self-efficacy and outcome expectations (i.e., tertiary outcomes).
CONCLUSIONS: By investigating the effectiveness of a pedometer-driven, face-to-face, and telephone-assisted counselling, behavior change intervention in complementary to usual rehabilitation, we hope to deliver applicable and generalizable knowledge to support physical activity after total hip arthroplasty and potentially enhance the outcome of the procedure.
