In Lieu of Smoking: Are Smokers More Likely to Enact Certain Types of Implementation Intention Plans During a JIT Smoking Cessation?

BACKGROUND: To identify actionable and effective implementation intention (II) plans, we examined whether (a) IIs suggesting food or nicotine-based substitution strategies to help quit smoking cigarettes would be more likely to be enacted in real time, (b) IIs reminding participants to cognitively motivate themselves or engage in solitary activity would be more likely to be enacted than those suggesting seeking social support, and (c) II plan enactment based on the above strategies would be associated with reporting momentary lapse avoidance. METHOD: A sample of 57 Asian American young adult (18-25 years) smokers participated in a 4-week, mobile-based smoking cessation intervention, implemented in a Just-In-Time framework. User-specified IIs were categorized into nature of activity (cognitively motivate themselves, engage in solitary activity, seek social support) and type of substitution strategy (food, nicotine, no substitution). Outcome variable was momentary enactment of the given II. Generalized mixed linear models were used for analyses. RESULTS: IIs reminding participants to cognitively motivate themselves and/or engage in solitary activities were more likely to be enacted than IIs recommending seeking social support. IIs recommending nicotine-based substitution were more likely to be enacted than IIs that did not specify any substitution. IIs suggesting food-based substitution, however, were less likely to be enacted than those not suggesting a specific substitution. II plan enactment based on the above strategies was significantly associated with avoiding momentary lapses compared to when momentary lapses occurred. CONCLUSION: Specifying II recommendations found to be helpful with avoiding lapses in a smoking cessation context, can increase chances of II enactment, and improve overall health intervention outcomes.

Yoga, Physical Therapy, or Education for Chronic Low Back Pain: A Randomized Noninferiority Trial.

BACKGROUND: Yoga is effective for mild to moderate chronic low back pain (cLBP), but its comparative effectiveness with physical therapy (PT) is unknown. Moreover, little is known about yoga's effectiveness in underserved patients with more severe functional disability and pain. OBJECTIVE: To determine whether yoga is noninferior to PT for cLBP. DESIGN: 12-week, single-blind, 3-group randomized noninferiority trial and subsequent 40-week maintenance phase. (ClinicalTrials.gov: NCT01343927). SETTING: Academic safety-net hospital and 7 affiliated community health centers. PARTICIPANTS: 320 predominantly low-income, racially diverse adults with nonspecific cLBP. INTERVENTION: Participants received 12 weekly yoga classes, 15 PT visits, or an educational book and newsletters. The maintenance phase compared yoga drop-in classes versus home practice and PT booster sessions versus home practice. MEASUREMENTS: Primary outcomes were back-related function, measured by the Roland Morris Disability Questionnaire (RMDQ), and pain, measured by an 11-point scale, at 12 weeks. Prespecified noninferiority margins were 1.5 (RMDQ) and 1.0 (pain). Secondary outcomes included pain medication use, global improvement, satisfaction with intervention, and health-related quality of life. RESULTS: One-sided 95% lower confidence limits were 0.83 (RMDQ) and 0.97 (pain), demonstrating noninferiority of yoga to PT. However, yoga was not superior to education for either outcome. Yoga and PT were similar for most secondary outcomes. Yoga and PT participants were 21 and 22 percentage points less likely, respectively, than education participants to use pain medication at 12 weeks. Improvements in yoga and PT groups were maintained at 1 year with no differences between maintenance strategies. Frequency of adverse events, mostly mild self-limited joint and back pain, did not differ between the yoga and PT groups. LIMITATIONS: Participants were not blinded to treatment assignment. The PT group had disproportionate loss to follow-up. CONCLUSION: A manualized yoga program for nonspecific cLBP was noninferior to PT for function and pain.

Development of a Just-in-Time Adaptive Intervention for Smoking Cessation Among Korean American Emerging Adults.

PURPOSE: Cigarette smoking is a preventable risk factor that contributes to unnecessary lung cancer burden among Korean Americans and there is limited research on effective smoking cessation strategies for this population. Smartphone-based smoking cessation apps that leverage just-in-time adaptive interventions (JITAIs) hold promise for smokers attempting to quit. However, little is known about how to develop and tailor a smoking cessation JITAI for Korean American emerging adult (KAEA) smokers. METHOD: This paper documents the development process of MyQuit USC according to design guidelines for JITAI. Our development process builds on findings from a prior ecological momentary assessment study by using qualitative research methods. Semi-structured interviews and a focus group were conducted to inform which intervention options to offer and the decision rules that dictate their delivery. RESULTS: Qualitative findings highlighted that (1) smoking episodes are highly context-driven and that (2) KAEA smokers believe they need personalized cessation strategies tailored to different contexts. Thus, MyQuit USC operates via decision rules that guide the delivery of personalized implementation intentions, which are contingent on dynamic factors, to be delivered "just in time" at user-scheduled, high-risk smoking situations. CONCLUSION: Through an iterative design process, informed by quantitative and qualitative formative research, we developed a smoking cessation JITAI tailored specifically for KAEA smokers. Further testing is under way to optimize future versions of the app with the most effective intervention strategies and decision rules. MyQuit USC has the potential to provide cessation support in real-world settings, when KAEAs need them the most.

Using Ecological Momentary Assessment to Identify Common Smoking Situations Among Korean American Emerging Adults.

The present study provides detailed contextual information about smoking habits among young Korean American smokers with the goal of characterizing situations where they are most at risk for smoking. Relevant situational factors included location, social context, concurrent activities, time of day, affective states, and food and beverage consumption. Using ecological momentary assessment (EMA) over 7 days, participants (N = 78) were instructed to respond to smoking prompts (n = 2614) and non-smoking prompts (n = 2136) randomly scheduled throughout the day. At each prompt, participants completed a short survey about immediate contextual factors. We used multilevel models to evaluate the association between contextual factors and smoking and further explored the distribution of smoking locations and concurrent activities across each social context and reason for smoking. Compared to non-smoking events, smoking events were associated with being outside, the presence of Korean friends, socializing, consuming alcohol, and experiencing more stress relative to one's average stress level (all ps < .01). Further analyses involving only smoking events showed that when participants smoked alone, they were most commonly at home (50 %) and most often studying/working (28 %). When smoking with Korean friends, participants were most often outside (38 %) and socializing (54 %). When smoking to reduce craving, participants were most often at home (39 %) and studying/working (25 %). To our knowledge, this is the first study to provide detailed descriptions of real-time smoking contexts among young Korean American smokers. Information with this level of granularity is needed to develop effective just-in-time adaptive interventions (JITAIs) for smoking cessation.

Momentary negative moods and being with friends precede cigarette use among Korean American emerging adults.

INTRODUCTION: The objective of this study was to determine contextual antecedents to smoking among Korean American emerging adult (KAEA) smokers using ecological momentary assessment. Based on extant theory and data documenting the importance of negative affect (NA) and social context, we examined the extent to which being with friends and NA independently and concomitantly were associated with the likelihood of subsequent smoking, over and beyond other known situational correlates of smoking. METHODS: Twenty-two KAEA daily smokers recorded their smoking events in real time and participated in short surveys implemented on mobile phones for 7 days. Individual, interpersonal, and situational contexts immediately preceding and during smoking events were examined in comparison to nonsmoking events using a within-subject modeling approach. RESULTS: Both NA and being with friends independently were correlated with increased likelihood of smoking. We also found an interaction showing that the effects of NA on smoking were significant only in presence of friends. CONCLUSIONS: Unlike more established smokers, these younger smokers may be strongly influenced by peer contexts as well as unpleasant affect. The interaction between social contexts and NA highlights a potential window for intervention for the population of KAEA smokers.

Behavioral Engagement and Activation Model Study (BEAMS): A latent class analysis of adopters and non-adopters of digital health technologies among people with Type 2 diabetes.

Many people with Type 2 diabetes (T2D) who could benefit from digital health technologies (DHTs) are either not using DHTs or do use them, but not for long enough to reach their behavioral or metabolic goals. We aimed to identify subgroups within DHT adopters and non-adopters and describe their unique profiles to better understand the type of tailored support needed to promote effective and sustained DHT use across a diverse T2D population. We conducted latent class analysis of a sample of adults with T2D who responded to an internet survey between December 2021 and March 2022. We describe the clinical and psychological characteristics of DHT adopters and non-adopters, and their attitudes toward DHTs. A total of 633 individuals were characterized as either DHT "Adopters" (n = 376 reporting any use of DHT) or "Non-Adopters" (n = 257 reporting never using any DHT). Within Adopters, three subgroups were identified: 21% (79/376) were "Self-managing Adopters," who reported high health activation and self-efficacy for diabetes management, 42% (158/376) were "Activated Adopters with dropout risk," and 37% (139/376) were "Non-Activated Adopters with dropout risk." The latter two subgroups reported barriers to using DHTs and lower rates of intended future use. Within Non-Adopters, two subgroups were identified: 31% (79/257) were "Activated Non-Adopters," and 69% (178/257) were "Non-Adopters with barriers," and were similarly distinguished by health activation and barriers to using DHTs. Beyond demographic characteristics, psychological, and clinical factors may help identify different subgroups of Adopters and Non-Adopters.

In this study, we characterized subgroups of adopters and non-adopters of digital health technologies (DHTs) for managing Type 2 diabetes, such as apps to track nutrition, continuous glucose monitors, and activity monitors like Fitbit. Self-efficacy for diabetes management, health activation, and perceived barriers to use DHT emerged as characteristics that distinguished subgroups. Notably, subgroups of adopters differed in their interest to use these technologies in the next 3 months; groups with low levels of self-efficacy and health activation were least interested in using them and thus at risk of discontinuing use. The ability to identify these subgroups can inform strategies tailored to each subgroup that motivate adoption of DHTs and promote long-term engagement.

Racial uplifts and the Asian American experience.

It is well established that experiences of racial discrimination pose a significant health risk to ethnic minority youth. In this article, we introduce a new concept, racial uplifts, to capture a largely neglected countertheme in the scientific literature-the nature and processes underlying salubrious race-related experiences. We report on data from a mixed-method study of everyday racial uplifts in the lives of Asian American youth. Study 1a (n = 20; age range = 17-23 years) and Study 1b (n = 14; age range = 18-22 years) examined data collected through semistructured focus group interviews. Study 2 used data from a 14-day diary study (n = 152; age range = 16-20 years). A consensual qualitative research analysis of interview data revealed six major racial uplifting themes: (a) ethnic bonding, (b) overcoming obstacles, (c) bicultural competence, (d) cultural bridging, (e) globalism, and (f) outgroup regard. Analysis of end-of-day diary data revealed that respondents reported at least one daily racial uplift on 65% of the study days and multiple uplifts on 42% of the study days. Multilevel analyses indicated that everyday racial uplifts were associated with decreased daily negative affect and increased daily positive affect and self-esteem. The results add to a growing literature on the role of assets and promotive resources in the lives of ethnic minority youth. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Pilot Results of a Digital Hypertension Self-management Program Among Adults With Excess Body Weight: Single-Arm Nonrandomized Trial.

BACKGROUND: Home-measured blood pressure (HMBP) in combination with comprehensive medication support and lifestyle change are the mainstays of evidence-based hypertension (HTN) management. To date, the precise components needed for effective HTN self-management programs have yet to be defined, and access to multicomponent targeted support for HTN management that include telemonitoring remain inaccessible and costly. OBJECTIVE: The aim of this pilot study was to evaluate the impact of a digital HTN self-management program on blood pressure (BP) control among adults with excess body weight. METHODS: A single-arm, nonrandomized trial was performed to evaluate a digital HTN self-management program that combines comprehensive lifestyle counseling with HTN education, guided HMBP, support for taking medications, and led by either a registered nurse or certified diabetes care and education specialist. A sample of 151 participants were recruited using a web-based research platform (Achievement Studies, Evidation Health Inc). The primary outcome was change in systolic BP from baseline to 3 months, and secondary outcomes included change in diastolic BP and medication adherence. RESULTS: Participants' mean age was 44.0 (SD 9.3) years and mean BP was 139/85 mm Hg. At follow-up, systolic and diastolic BP decreased by 7 mm Hg (P<.001, 95% CI -9.3 to -4.7) and 4.7 mm Hg (P<.001, 95% CI -6.3 to -3.2), respectively. Participants who started with baseline BP at goal remained at goal. For participants with stage 1 HTN, systolic and diastolic BP decreased by 3.6 mm Hg (P=.09, 95% CI -7.8 to 0.6) and 2.5 mm Hg (P=.03, 95% CI -4.9 to -0.3). Systolic and diastolic BP decreased by 10.3 mm Hg (P<.001, 95% CI -13.4 to -7.1) and 6.5 mm Hg (P<.001, 95% CI -8.6 to -4.4), respectively, for participants with stage 2 HTN. Medication adherence significantly improved (P=.02). CONCLUSIONS: This pilot study provides initial evidence that a digital HTN self-management program improves BP and medication adherence.

A Prospective Real-World Study Exploring Associations Between Passively Collected Tracker Data and Headache Burden Among Individuals with Tension-Type Headache and Migraine.

INTRODUCTION: Prevalence and burden of headache disorders in real-world settings is relatively unstudied. We explored the associations between passively collected activity data, headache burden, and quality of life in headache sufferers. METHODS: Data from wearable activity tracking devices and daily short questionnaires were collected over 12 weeks to assess occurrence of headache, activity, quality of life and self-rated health. Variables were analyzed using a series of mixed-effects models and stratified based on headache type. Multiple linear and logistic regressions were used to analyze treatment preferences. RESULTS: Behaviors inferred from activity tracker data suggested that individuals slept more, had reduced physical activity, and had lower maximum heart rate on days with headache. As headache-specific impact on quality of life increased, activity and maximum heart rate decreased and sleep increased. Headache days with higher self-rated health were associated with less napping, higher step count and maximum heart rate, correlating with increased activity. Migraineurs experienced greater burden in everyday life compared with tension-type headache sufferers. CONCLUSION: This study adds to existing evidence that activity trackers can be used to quantify headache burden in real-world settings and aid in understanding symptom management.

Effect of a mobile just-in-time implementation intention intervention on momentary smoking lapses in smoking cessation attempts among Asian American young adults.

Identifying vulnerable windows for a given problematic behavior and providing timely and appropriate support are critical for building an effective just-in-time (JIT) intervention for behavioral change. We developed and evaluated an implementation intention (II) based, JIT cessation intervention prototype to support Asian American young adult smokers to prevent lapses in their cessation attempts in real-time. We examined how a JIT II reminder may prevent lapses during self-identified high-risk smoking situation (HRSS) as a microtemporal process. We also tested whether the effect of JIT reminder changes over the course of study and differed between those who used their own versus project loan phones. Asian American young adult smokers (N = 57) who were interested in quitting or reducing smoking participated in a 4 week, mobile-based, cessation study (MyQuit USC, MQU). MQU is a JIT mobile app that deploys a user-specified II reminder at user-specified HRSS and assesses momentary lapse status. Generalized mixed linear models were conducted to assess the effect of the JIT intervention on lapse prevention. We found a significant interaction effect (p = .03) such that receiving JIT reminder reduced the likelihood of lapses for participants using their own phones but not for the loaners. The results also showed that when participants enacted the suggested II, they were less likely to lapse (p < .001). The JIT effect did not change over time in study (p = .21). This study provides evidence that receiving a reminder of a smoker's own plan just before a self-identified risky situation on a familiar device and successfully executing specified plans can be helpful in preventing lapses. Our results highlighted factors to consider when designing and refining a JIT intervention.

Early Insights From a Digitally Enhanced Diabetes Self-Management Education and Support Program: Single-Arm Nonrandomized Trial.

BACKGROUND: Translation of diabetes self-management education and support (DSMES) into a digital format can improve access, but few digital programs have demonstrated outcomes using rigorous evaluation metrics. OBJECTIVE: The aim of this study was to evaluate the impact of a digital DSMES program on hemoglobin A1c (HbA1c) for people with type 2 diabetes. METHODS: A single-arm, nonrandomized trial was performed to evaluate a digital DSMES program that includes remote monitoring and lifestyle change, in addition to comprehensive diabetes education staffed by a diabetes specialist. A sample of 195 participants were recruited using an online research platform (Achievement Studies, Evidation Health Inc). The primary outcome was change in laboratory-tested HbA1c from baseline to 4 months, and secondary outcomes included change in lipids, diabetes distress, and medication adherence. RESULTS: At baseline, participants had a mean HbA1c of 8.9% (SD 1.9) and mean BMI of 37.5 kg/m2 (SD 8.3). The average age was 45.1 years (SD 8.9), 70% were women, and 67% were White. At 4-month follow up, the HbA1c decreased by 0.8% (P<.001, 95% CI -1.1 to -0.5) for the total population and decreased by 1.4% (P<.001, 95% CI -1.8 to -0.9) for those with an HbA1c of >9.0% at baseline. Diabetes distress and medication adherence were also significantly improved between baseline and follow up. CONCLUSIONS: This study provides early evidence that a digitally enhanced DSMES program improves HbA1c and disease self-management outcomes.

Correlates of Perceived Smoking Prevalence Among Korean American Emerging Adults.

Perceived smoking prevalence, a strong predictor of actual smoking behavior, may be influenced by the ethnicity and gender of the reference group presented to Korean American emerging adults. Self-identifying Korean and Korean Americans aged 18-25 (N = 475), were invited to complete a 15-20 min online survey about their attitudes towards smoking. Predictors of perceived smoking prevalence were evaluated separately for four reference groups: Caucasian Americans, Korean Americans in general, Korean American men, and Korean American women. Respondents' smoking status was associated with perceived smoking prevalence for all reference groups except Caucasian Americans, even among light smokers. Father's smoking status was associated with perceived smoking prevalence for Korean American men, only among females respondents. Findings suggest that ethnicity and gender of both the reference group and respondents influence smoking rate estimates. Tailoring intervention content to the target population's gender and ethnicity may be a way to enhance smoking prevention strategies.

Social contexts of momentary craving to smoke among Korean American emerging adults.

INTRODUCTION: Korean American emerging adult (KAEA) smokers represent a culturally and developmentally unique population constituted of primarily light, intermittent smokers. Sociocultural contexts might play an important role in contributing to instances of acute cigarette craving and motivation to smoke in this population; yet, research testing such hypotheses is scant. The current study tests whether and how social contexts are associated with the craving among KAEA smokers. METHODS: Seventy-eight daily KAEA smokers, who smoke 4+ cigs/day, participated in a 7-day ecological momentary assessment (EMA), in which participants responded to both signal-contingent (random) and event-contingent (smoking) prompts to answer surveys on their mobile phones (prompt-level n=1377; 603 random +774 smoking prompts). Nicotine dependence was measured at baseline; cigarette craving, negative affect, presence of others smoking, social contexts were measured with EMA. RESULTS: Modeling of within-participant variation and covariation showed that being with Korean friends (vs. alone) was associated with increased levels of momentary craving. This association between Korean friends and craving disappeared when adjusted for presence of others smoking, which was a strong predictor of momentary craving. The positive association between Korean friends and craving was amplified immediately prior to smoking (vs. non-smoking random) instances. CONCLUSIONS: Being with Korean friends might serve as a culturally-specific salient smoking cue, which might have been learned throughout their smoking history. Our data also showed that increased craving associated with Korean friends may represent social settings that primarily involve cigarette smoking. Given our findings on cigarette use among KAEA's social network, addressing cigarette use as a group behavior might be a fruitful intervention strategy.

Inter-method reliability of paper surveys and computer assisted telephone interviews in a randomized controlled trial of yoga for low back pain.

BACKGROUND: Little is known about the reliability of different methods of survey administration in low back pain trials. This analysis was designed to determine the reliability of responses to self-administered paper surveys compared to computer assisted telephone interviews (CATI) for the primary outcomes of pain intensity and back-related function, and secondary outcomes of patient satisfaction, SF-36, and global improvement among participants enrolled in a study of yoga for chronic low back pain. RESULTS: Pain intensity, back-related function, and both physical and mental health components of the SF-36 showed excellent reliability at all three time points; ICC scores ranged from 0.82 to 0.98. Pain medication use showed good reliability; kappa statistics ranged from 0.68 to 0.78. Patient satisfaction had moderate to excellent reliability; ICC scores ranged from 0.40 to 0.86. Global improvement showed poor reliability at 6 weeks (ICC = 0.24) and 12 weeks (ICC = 0.10). CONCLUSION: CATI shows excellent reliability for primary outcomes and at least some secondary outcomes when compared to self-administered paper surveys in a low back pain yoga trial. Having two reliable options for data collection may be helpful to increase response rates for core outcomes in back pain trials. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01761617.

Yoga vs. physical therapy vs. education for chronic low back pain in predominantly minority populations: study protocol for a randomized controlled trial.

BACKGROUND: Chronic low back pain causes substantial morbidity and cost to society while disproportionately impacting low-income and minority adults. Several randomized controlled trials show yoga is an effective treatment. However, the comparative effectiveness of yoga and physical therapy, a common mainstream treatment for chronic low back pain, is unknown. METHODS/DESIGN: This is a randomized controlled trial for 320 predominantly low-income minority adults with chronic low back pain, comparing yoga, physical therapy, and education. Inclusion criteria are adults 18-64 years old with non-specific low back pain lasting ≥ 12 weeks and a self-reported average pain intensity of ≥ 4 on a 0-10 scale. Recruitment takes place at Boston Medical Center, an urban academic safety-net hospital and seven federally qualified community health centers located in diverse neighborhoods. The 52-week study has an initial 12-week Treatment Phase where participants are randomized in a 2:2:1 ratio into i) a standardized weekly hatha yoga class supplemented by home practice; ii) a standardized evidence-based exercise therapy protocol adapted from the Treatment Based Classification method, individually delivered by a physical therapist and supplemented by home practice; and iii) education delivered through a self-care book. Co-primary outcome measures are 12-week pain intensity measured on an 11-point numerical rating scale and back-specific function measured using the modified Roland Morris Disability Questionnaire. In the subsequent 40-week Maintenance Phase, yoga participants are re-randomized in a 1:1 ratio to either structured maintenance yoga classes or home practice only. Physical therapy participants are similarly re-randomized to either five booster sessions or home practice only. Education participants continue to follow recommendations of educational materials. We will also assess cost effectiveness from the perspectives of the individual, insurers, and society using claims databases, electronic medical records, self-report cost data, and study records. Qualitative data from interviews will add subjective detail to complement quantitative data. TRIAL REGISTRATION: This trial is registered in ClinicalTrials.gov, with the ID number: NCT01343927.

Comparing Once- versus Twice-Weekly Yoga Classes for Chronic Low Back Pain in Predominantly Low Income Minorities: A Randomized Dosing Trial.

Background. Previous studies have demonstrated that once-weekly yoga classes are effective for chronic low back pain (cLBP) in white adults with high socioeconomic status. The comparative effectiveness of twice-weekly classes and generalizability to racially diverse low income populations are unknown. Methods. We conducted a 12-week randomized, parallel-group, dosing trial for 95 adults recruited from an urban safety-net hospital and five community health centers comparing once-weekly (n = 49) versus twice-weekly (n = 46) standardized yoga classes supplemented by home practice. Primary outcomes were change from baseline to 12 weeks in pain (11-point scale) and back-related function (23-point modified Roland-Morris Disability Questionnaire). Results. 82% of participants were nonwhite; 77% had annual household incomes <$40,000. The sample's baseline mean pain intensity [6.9 (SD 1.6)] and function [13.7 (SD 5.0)] reflected moderate to severe back pain and impairment. Pain and back-related function improved within both groups (P < 0.001). However, there were no differences between once-weekly and twice-weekly groups for pain reduction [-2.1 (95% CI -2.9, -1.3) versus -2.4 (95% CI -3.1, -1.8), P = 0.62] or back-related function [-5.1 (95% CI -7.0, -3.2) versus -4.9 (95% CI -6.5, -3.3), P = 0.83]. Conclusions. Twelve weeks of once-weekly or twice-weekly yoga classes were similarly effective for predominantly low income minority adults with moderate to severe chronic low back pain. This trial is registered with ClinicalTrials.gov NCT01761617.
