Exploring Factors Associated with Dietary Improvement Among Participants Who Completed a Randomized Controlled Trial for Physical Activity: Evidence of a Transfer Effect.

BACKGROUND: This research aimed at understanding how changes in one behavior affect other behaviors, known as "transfer effect," could extend knowledge of shared constructs among compound health risk behaviors, and improve methods for promoting simultaneous behavior changes. The current study explored whether participants who completed a randomized controlled trial for physical activity (PA) improved their diet with no intervention in diet or nutrition. METHODS: US adults (N = 283) were randomly assigned to 12 weeks of either exercise videogames, standard exercise, or an attention control. Secondary analyses were conducted to examine a possible transfer effect of the intervention on diet at end of intervention (EOT) and 6-month follow-up. Assessments of potential PA constructs (i.e., exercise enjoyment, self-efficacy) and demographics (e.g., age, gender) were conducted. PA, specifically moderate-to-vigorous levels of physical activity (MVPA), was measured using a self-report measure. Diet was measured using the Rate Your Plate dietary assessment. RESULTS: Findings support that a randomization effect was associated with a higher likelihood of increasing MVPA (ß = 30.00, 95% CI = 4.46, 64.46) and dietary improvement at EOT (ß = 1.48, SE = .83, P = .01) and follow-up (ß = 1.74, SE = .52, P = .02). At EOT, changes in diet were associated with higher PA enjoyment (ß = 0.41, SE = 0.15, P = .01). This intervention effect on diet was moderated by gender, with women showing more dietary improvement than men (ß = - .78, SE = 13, P = .03). At 6 months, dietary improvement was associated with greater self-efficacy (ß = .04, SE = .01, P = .01). CONCLUSION: This study shows evidence of a transfer effect among two synergistic behaviors and expands understanding of factors that predict the occurrence of this type of behavior change.

Biological and psychological predictors of heart rate patterns during physical activity.

Objective: Latent class modeling (LCM) offers a promising approach for examining correlates of heart rate (HR) patterns over multiple exercise sessions. This research examined biological and psychological variables associated with different patterns of HR response to physical activity (PA). Methods: In a three-arm randomized controlled trial (exercise video games vs. standard exercise vs. non-exercise control), HR was recorded during PA sessions over a 12-week period. LCM identified three patterns of HR during PA across 189 participants in active arms: 1) high HR across sessions with low variability within sessions, 2) linear increase in HR across sessions with low variability within sessions, and 3) high variability in HR across all sessions. Associations with biological (resting heart rate, blood pressure, BMI, age, cholesterol, triglycerides, HbA1c) and psychological (depression, motivations for PA, PA-induced feelings) predictors of latent class membership were iteratively tested. Results: Psychological variables played as important a role in the final model as biological variables for predicting latent class membership. Few differences were found between LC1 and LC2, but LC3 differed from the other two groups in that participants were likelier to report that feel revitalized after PA (vs. LC1 and LC2), to be less motivated for PA (vs. LC1), reported greater depression (vs. LC1 and LC2), and were younger (vs. LC1). Conclusions: These findings demonstrate the potential of LCM to identify biological and psychological factors associated with chronotropic responses to PA, and advance understanding of the role of psychological factors in chronotropic PA outcomes.

Yoga as a Complementary Therapy for Smoking Cessation: Results From BreathEasy, a Randomized Clinical Trial.

INTRODUCTION: There is evidence that Yoga may be helpful as an aid for smoking cessation. Yoga has been shown to reduce stress and negative mood and may aid weight control, all of which have proven to be barriers to quitting smoking. This study is the first rigorous, randomized clinical trial of Yoga as a complementary therapy for smokers attempting to quit. METHODS: Adult smokers (N = 227; 55.5% women) were randomized to an 8-week program of cognitive-behavioral smoking cessation and either twice-weekly Iyengar Yoga or general Wellness classes (control). Assessments included cotinine-verified 7-day point prevalence abstinence at week 8, 3-month, and 6-month follow-ups. RESULTS: At baseline, participants' mean age was 46.2 (SD = 12.0) years and smoking rate was 17.3 (SD = 7.6) cigarettes/day. Longitudinally adjusted models of abstinence outcomes demonstrated significant group effects favoring Yoga. Yoga participants had 37% greater odds of achieving abstinence than Wellness participants at the end of treatment (EOT). Lower baseline smoking rates (≤10 cigarettes/day) were also associated with higher likelihood of quitting if given Yoga versus Wellness (OR = 2.43, 95% CI = 1.09% to 6.30%) classes at EOT. A significant dose effect was observed for Yoga (OR = 1.12, 95% CI = 1.09% to 1.26%), but not Wellness, such that each Yoga class attended increased quitting odds at EOT by 12%. Latent Class Modeling revealed a 4-class model of distinct quitting patterns among participants. CONCLUSIONS: Yoga appears to increase the odds of successful smoking abstinence, particularly among light smokers. Additional work is needed to identify predictors of quitting patterns and inform adjustments to therapy needed to achieve cessation and prevent relapse. IMPLICATIONS: This study adds to our knowledge of the types of physical activity that aid smoking cessation. Yoga increases the odds of successful smoking abstinence, and does so in a dose-response manner. This study also revealed four distinct patterns of smoking behavior among participants relevant to quitting smoking. Additional work is needed to determine whether variables that are predictive of these quitting patterns can be identified, which might suggest modifications to therapy for those who are unable to quit.

Using Relational Agents to Promote Exercise and Sun Protection: Assessment of Participants' Experiences With Two Interventions.

BACKGROUND: Relational agents (RAs) are electronic computational figures designed to engage participants in the change process. A recent study, Project RAISE, tested the effectiveness of RAs, combined with existing computer-based interventions to increase regular exercise and sun protection behaviors. Results showed these interventions can be effective but need further development. OBJECTIVE: The purpose of this study was to examine participants' experiences using RAs to increase participant engagement and promote behavior change . METHODS: A qualitative approach was primarily utilized. A 25-question interview guide assessed different components of participants' experiences with the intervention, including motivation, engagement, satisfaction or dissatisfaction, quality of their interaction with the RA, and behavior change. Quantitative assessment of satisfaction was based on a scale of 1 to 10, with 1 representing least satisfied and 10 representing most satisfied. A summative analytic approach was used to assess individuals' qualitative responses. A single analysis of variance (ANOVA) examined levels of satisfaction by gender. RESULTS: Of the original 1354 participants enrolled in Project RAISE, 490 of 1354 (36%) were assigned to the RA group. A sample of 216 out of 490 (44%) participants assigned to the RA group completed the interventions, and follow-up assessments were contacted to participate in the semistructured interview. A total of 34 out of 216 (16%) completed the interview. Participants were motivated by, and satisfied with, the intervention. Participants viewed the RA as supportive, informative, caring, and reported positive behavior change in both exercise and sun protection. Some participants (15/34, 44%) noted the RA was less judgmental and less "overbearing" compared with a human counselor; other participants (12/34, 35%) said that the interaction was sometimes repetitive or overly general. The majority of participants (22/34, 65%) viewed the RA as an important contributor to their behavior change for exercise, sun protection, or both. Levels of satisfaction ranged between 7 and 10. There were no gender differences noted in levels of satisfaction (P=.51). CONCLUSIONS: RAs provide an innovative and attractive platform to increase exercise and sun protection behaviors and potentially other health behaviors.

Comparing the Validity of Self-Report and Urinalysis for Substance Use among Former Inmates in the Northeastern United States.

BACKGROUND: Problems with self-reported drug use include difficulties with recall and recognition as well as the desire to respond to questions in a socially desirable manner. Various methods have been developed to improve and/or validate estimates based on direct questioning of individuals regarding their substance use. For this study, we were interested in validating self-reported use of: 1) tobacco, 2) marijuana, and 3) other substances (i.e., heroin, cocaine, opiates, oxycodone, benzodiazepines, methamphetamine, phencyclidine, and barbiturates) employing urinalysis among inmates who participated in a randomized controlled trial of a smoking abstinence intervention in a tobacco-free prison located in the northeastern United States. METHODS: Two-hundred and seven men and women with a mean age of 34.9 (standard deviation = 9.0) completed questions regarding their substance use on a 7-day Timeline Follow-Back and provided urine specimens three weeks following prison release. RESULTS: Self-reported tobacco and marijuana use were highly consistent with urine drug testing in terms of overall agreement and Kappa (93.7% and.804 for tobacco, respectively; and 90.3% and.804 for marijuana, respectively); however, consistency was much lower for other drug use grouped together (62.7% and.270). DISCUSSION: Although some former inmates may not accurately report substance use, our findings indicate that they are in the minority, suggesting that self-report is valid for tobacco and marijuana use but much less so for other drugs grouped together. Future research should be conducted with a larger and more diverse sample of former inmates to establish the generalizability of our findings from this study.

A Pilot Randomized Controlled Trial of a Technology-Based Substance Use Intervention for Youth Exiting Foster Care.

Youth exiting foster care represent a unique, at-risk population in that they receive supportive health services while under the umbrella of the foster care system, but access to care can drop precipitously upon release from foster custody. Traditional means of substance use treatment may not meet the needs of this vulnerable population. Mobile interventions, however, have demonstrated high acceptability and efficacy across a range of mental and physical health issues. The specific advantages to mobile interventions dovetail well with the barriers faced by youth exiting foster care. This study describes the feasibility, acceptability, and initial efficacy of iHeLP, a computer- and mobile phone-based intervention based in Motivational Interviewing for reducing substance use among youth exiting foster care (n = 33). Participants were randomly assigned to either iHeLP or a contact control, each of which lasted six months. Feasibility was evaluated through eligibility and enrollment rates at baseline, and retention and intervention reach rates 3, 6, 9, and 12 months later. Acceptability was measured through a 5-item satisfaction measure and exit interviews. The two groups were then compared on a monthly measure of substance use. Study enrollment, retention, response rate, engagement, and satisfaction were all very good. Participants receiving iHeLP reported higher percent days abstinent than the control group, with effect sizes ranging from 0.32 to 0.62. Technology-based interventions such as iHeLP may be attractive to this population and support efforts towards reductions in substance use.

The effects of yoga among adults with type 2 diabetes: A systematic review and meta-analysis.

The purpose of this meta-analysis was to examine the effects of yoga for glycemic control among adults with type 2 diabetes (T2DM). Comprehensive electronic databases searches located 2559 unique studies with relevant key terms. Studies were included if they (1) evaluated a yoga intervention to promote T2DM management, (2) used a comparison group, (3) reported an objective measure of glycemic control at post-intervention, and (4) had follow-up length or post-test of at least 8weeks from baseline. Independent raters coded participant, design and methodological characteristics and intervention content. Summary effect sizes and 95% confidence intervals (CI) were calculated. Twenty-three studies with 2473 participants (mean age=53years; 43% women) met eligibility criteria. Compared with controls, yoga participants were successful in improving their HbA1c (d+=0.36, 95% CI=0.16, 0.56; k=16), FBG (d+=0.58, 95% CI=0.40, 0.76; k=20), and PPBG (d+=0.40, 95% CI=0.23, 0.56; k=14). Yoga was also associated with significant improvements in lipid profile, blood pressure, body mass index, waist/hip ratio and cortisol levels. Overall, studies satisfied an average of 41% of the methodological quality (MQ) criteria; MQ score was not associated with any outcome (Ps >0.05). Yoga improved glycemic outcomes and other risk factors for complications in adults with T2DM relative to a control condition. Additional studies with longer follow-ups are needed to determine the long-term efficacy of yoga for adults with T2DM.

Physical activity maintenance among Spanish-speaking Latinas in a randomized controlled trial of an Internet-based intervention.

Spanish-speaking Latinas have some of the lowest rates of meeting physical activity guidelines in the U.S. and are at high risk for many related chronic diseases. The purpose of the current study was to examine the maintenance of a culturally and individually-tailored Internet-based physical activity intervention for Spanish-speaking Latinas. Inactive Latinas (N  =  205) were randomly assigned to a 6-month Tailored Physical Activity Internet Intervention or a Wellness Contact Control Internet Group, with a 6-month follow-up. Maintenance was measured by assessing group differences in minutes per week of self-reported and accelerometer measured moderate to vigorous physical activity (MVPA) at 12 months after baseline and changes in MVPA between the end of the active intervention (month 6) and the end of the study (month 12). Potential moderators of the intervention were also examined. Data were collected between 2011 and 2014, and were analyzed in 2015 at the University of California, San Diego. The Intervention Group engaged in significantly more minutes of MVPA per week than the Control Group at the end of the maintenance period for both self-reported (mean diff. = 30.68, SE = 11.27, p = .007) and accelerometer measured (mean diff. = 11.47, SE = 3.19, p = .01) MVPA. There were no significant between- or within-group changes in MVPA from month 6 to 12. Greater intervention effects were seen for those with lower BMI (BMI × intervention = -6.67, SE = 2.88, p = .02) and lower perceived places to walk to in their neighborhood (access × intervention = -43.25, SE = 19.07, p = .02), with a trend for less family support (social support × intervention = -3.49, SE = 2.05, p = .08). Acculturation, health literacy, and physical activity related psychosocial variables were not significant moderators of the intervention effect during the maintenance period. Findings from the current study support the efficacy of an Internet-delivered individually tailored intervention for maintenance of MVPA gains over time.

Developing a Tailored Texting Preventive Intervention: A Card Sort Methodology.

PURPOSE: Intervention content written by adults for youth can result in miscommunication due to generational and cultural differences. Inviting at-risk youth to participate in the creation of intervention material can augment acceptability for their peers. METHODS: To improve intervention messaging, the present study examines the utility of a card sort technique when creating cellular phone text messages to be used in a preventive substance use intervention. During focus groups with 24 youth who are exiting the foster care system - a population with distinct cultural attributes - participants were asked to rate stage of change-specific health messages rooted in Motivational Interviewing and the Transtheoretical Model. RESULTS: Participants unanimously favored content that encouraged autonomy and choice. Statements that invited a "look to the future" were also rated favorably. Messages that referenced the past were not rated well, as were suggestions for professional assistance. Finally, encouragement to receive social support for change was met with ambivalence. While some participants regarded support as helpful, many others felt a severe lack of support in their lives, possibly prompting further substance use. CONCLUSIONS: Youth exiting foster care constitute a unique population whose voice is paramount in the development of interventions. The content present in traditional approaches to substance use prevention (e.g., increasing social support) may not apply to this group of vulnerable youth. The card sort technique has strong potential to evoke youth-specific intervention content that is more readily understood and accepted by target audiences.

Pasos Hacia La Salud: a randomized controlled trial of an internet-delivered physical activity intervention for Latinas.

BACKGROUND: Internet access has grown markedly in Latinos during the past decade. However, there have been no Internet-based physical activity interventions designed for Latinos, despite large disparities in lifestyle-related conditions, such as obesity and diabetes, particularly in Latina women. The current study tested the efficacy of a 6-month culturally adapted, individually tailored, Spanish-language Internet-based physical activity intervention. METHODS: Inactive Latinas (N = 205) were randomly assigned to the Tailored Physical Activity Internet Intervention or the Wellness Contact Control Internet Group. Participants in both groups received emails on a tapered schedule over 6 months to alert them to new content on the website. The primary outcome was minutes/week of moderate to vigorous physical activity (MVPA) at 6 months as measured by the 7-Day Physical Activity Recall; activity was also measured by accelerometers. Data were collected between 2011 and 2014 and analyzed in 2015 at the University of California, San Diego. RESULTS: Increases in minutes/week of MVPA were significantly greater in the Intervention Group compared to the Control Group (mean difference = 50.00, SE = 9.5, p < 0.01). Increases in objectively measured MVPA were also significantly larger in the Intervention Group (mean differences = 31.0, SE = 10.7, p < .01). The Intervention Group was also significantly more likely to meet national physical activity guidelines at 6 months (OR = 3.12, 95% CI 1.46-6.66, p < .05). CONCLUSION: Findings from the current study suggest that this Internet-delivered individually tailored intervention successfully increased MVPA in Latinas compared to a Wellness Contact Control Internet Group. TRIAL REGISTRATION: NCT01834287.

Testing a Dynamic Automated Substance Use Intervention Model for Youths Exiting Foster Care.

With an ever increasing gap between need and availability for substance use services, more scalable and efficient interventions are needed. For youth in the foster care system, this gap is dramatic and expands as they leave care. Effective prevention services are strongly needed for this group of vulnerable young people. We propose a novel technology-driven intervention for preventing problematic substance use among youth receiving foster care services. This intervention approach would extend the work in brief computerized interventions by adding a text message-based booster, dynamically tailored to each individual's readiness to change. It also combats many barriers to service receipt. Dynamically tailored interventions delivered through technologies commonly used by adolescents and young adults have the strong potential to reduce the burden of problematic substance use.

Tobacco cessation among low-income smokers: motivational enhancement and nicotine patch treatment.

INTRODUCTION: Despite decades of tobacco use decline among the general population in the United States, tobacco use among low-income populations continues to be a major public health concern. Smoking rates are higher among individuals with less than a high school education, those with no health insurance, and among individuals living below the federal poverty level. Despite these disparities, smoking cessation treatments for low-income populations have not been extensively tested. In the current study, the efficacy of 2 adjunctive smoking cessation interventions was evaluated among low-income smokers who were seen in a primary care setting. METHODS: A total of 846 participants were randomly assigned either to motivational enhancement treatment plus brief physician advice and 8 weeks of nicotine replacement therapy (NRT) or to standard care, which consisted of brief physician advice and 8 weeks of NRT. Tobacco smoking abstinence was at 1, 2, 6, and 12 months following baseline. RESULTS: The use of the nicotine patch, telephone counseling, and positive decisional balance were predictive of increased abstinence rates, and elevated stress levels and temptation to smoke in both social/habit and negative affect situations decreased abstinence rates across time. Analyses showed intervention effects on smoking temptations, length of patch use, and number of telephone contacts. Direct intervention effects on abstinence rates were not significant, after adjusting for model predictors and selection bias due to perirandomization attrition. CONCLUSIONS: Integrating therapeutic approaches that promote use of and adherence to medications for quitting smoking and that target stress management and reducing negative affect may enhance smoking cessation among low-income smokers.

Assessing Hair Concerns and Physical Activity Measures Among African American Women: a Mixed-Method Exploratory Study.

OBJECTIVES: Research on the association between hair concerns and physical activity (PA) constructs among African American (AA) women is lacking. Demographics such as age and income are indicated to influence hair concerns. In this study, quantitative methods were used to assess demographic differences in hair concerns and associations between hair concerns and PA. Qualitative interviewing explored AA women's views about their hair and engagement in PA. METHODS: Participants (n = 48; M age = 37.57, SD = 13.72) completed a survey that included demographics, hair type and hairstyle management (HTHM), decisional balance (pros, cons), perceived benefits and perceived barriers scale, and level of physical activity. HTHM consists of six items measuring different factors related to hair concerns. 25 completed a qualitative interview. Chi-square or analysis of variance tests were conducted as appropriate. Qualitative data were analyzed using content analysis. RESULTS: Proportion differences were noted between age groups (≤ 32 vs. ≥ 33) and average cost of haircare per month (p = .048). A statistically significant effect was noted for average monthly haircare cost and pros (p = .05), and for alter behavior due to hair concerns and perceived benefits to physical activity (p = .05). For level of physical activity, proportion differences were noted between exercisers and non-exercisers for average minutes spent on hair care (p = .009). Qualitative results showed few participants view hair concern as an important barrier to PA. Some participants suggested strategies for overcoming hair concerns to exercise (e.g., braids, twists). CONCLUSION: Implications of findings including development of PA intervention approaches that may appeal to AA women are discussed.

Perceived delivery of essential yoga properties within in-person and remote weight loss maintenance interventions.

OBJECTIVES: While previous research has utilized remote delivery of yoga interventions, no research has specifically interrogated the effectiveness of remote yoga intervention delivery. In this secondary analysis of weight-maintenance trial data, we examined participant perceptions of essential yoga properties across in-person and remote formats, hypothesizing that perceptions would not differ following remote delivery. METHODS: 24 women with overweight or obesity (34.6±4.1 kg/m2, 48.2±9.9 years) received a 12-week Iyengar yoga intervention (2x/week) following a 3-month behavioral weight loss program. Of 23 participants who completed follow-up questionnaires, 12 received the planned in-person intervention and 11 received a remote intervention (delivered live) due to the COVID-19 pandemic. The Essential Properties of Yoga Questionnaire (EPYQ) was completed online by participants and by the instructors to measure the perceptions of the relative emphasis placed on the essential components of the yoga intervention via 14 subscales. Linear regression models were used to compare perceptions of each EPYQ dimension across in-person and remote delivery methods, as well as between participants and instructors, independent of delivery method. RESULTS: 13 of the 14 subscales did not differ between delivery modalities (p>0.05). Participants perceived more individual attention within in-person yoga (p = 0.003). For both delivery methods, instructors perceived breathwork, restorative postures, and body locks to be incorporated to a lesser degree compared to participants (ß = -1.28, p = 0.003; ß = -1.57, p = 0.019; ß = -1.39, p = 0.036; respectively). No other significant differences across the participant and instructor scores were observed. CONCLUSIONS: Findings provide preliminary support for the use of live remote delivery of yoga, effectively communicating most essential yoga properties when compared to in-person classes. However, participants perceived more individual attention with in-person versus remote delivery; thus, future remote-based yoga interventions may benefit from providing additional individualized feedback.

Technology-Based Smoking Cessation for Youth Exiting Foster Care: A Pilot Randomized Trial.

Despite high rates of cigarette use, little attention has been paid to screening and cessation services for youth in foster care. Study aims were to test the feasibility, acceptability, and preliminary efficacy of a technology-based smoking cessation intervention. Study enrollment, satisfaction, and engagement were high in the intervention arm, where readiness to change also significantly increased over time. Intervention and control participants significantly reduced cigarette use at 6-month follow up, though groups did not differ. Technology-based interventions appear to be attractive and offer a potentially scalable link to health care that this vulnerable population may not otherwise seek.

Pasos Hacia La Salud II: A Superiority RCT Utilizing Technology to Promote Physical Activity in Latinas.

INTRODUCTION: Latinas face an increased risk for chronic diseases associated with insufficient physical activity (PA). The researchers previously showed that a website-based intervention could increase PA among insufficiently active Latinas, yet rates of meeting national PA guidelines were low. The original intervention was enhanced by adding additional features, content, and points of contact, including via text messaging. This study tests the efficacy of the enhanced intervention compared with the original, aimed at maximizing and sustaining PA gains across 24 months. It also examines if increases in PA differed by baseline PA. STUDY DESIGN: The researchers conducted a superiority randomized controlled trial (data collected 2018-2022, analyzed 2023). SETTING/PARTICIPANTS: Participants were 195 Spanish-speaking Latinas ages 18-65 in the Providence, RI area. INTERVENTION: The original intervention is an empirically supported Spanish-language, individually-tailored, website-delivered PA intervention. The enhanced intervention includes text messaging and additional data-driven content and interactive features. MAIN OUTCOME MEASURES: Total weekly minutes of moderate to vigorous PA (MVPA) was measured via accelerometry and self-report at 6, 12, 18, and 24 months. RESULTS: Participants in both groups increased their MVPA over 24 months. There were no significant between-group differences at 6 or 12 months; at 18 months the enhanced intervention group had higher levels of self-reported (mean (sd): 90.35 (43.55) vs 70.18 [9.99]) and accelerometer-measured (66.21 [18.26] vs 60.27 [16.00]) MVPA compared to the original intervention group. They also had higher levels of self-reported (111.17 [23.35] vs 81.44 [1.82]) and accelerometer-measured (63.76 [15.12] vs 54.86 [14.59]) MVPA at 24 months. Baseline PA moderated the intervention effect. CONCLUSIONS: This study demonstrates the potential to enhance the efficacy of website-based PA interventions by utilizing text messaging, and adding more interactive features, content, and phone support. These enhancements may be particularly beneficial in supporting long-term PA maintenance. TRIAL REGISTRATION: This study is registered at www. CLINICALTRIAL: gov (NCT03491592).

Greater engagement in valued activities is associated with less barriers to quitting smoking among smokers with mobility impairments.

BACKGROUND: Individuals with mobility impairments (MI; use equipment to ambulate) have a high prevalence of both smoking and depression. Behavioral activation (BA) purports that depressed mood is remediated through valued activity engagement and may facilitate smoking cessation in MI populations. OBJECTIVE: We examined cross-sectional associations between activity engagement and variables important for smoking cessation among a high-risk group of smokers (people with MIs) and also describe a smoking cessation intervention based on BA, given the lack of studies on smokers with MIs. METHODS: This study used data from a smoking cessation trial enrolling smokers with MIs (n = 263). We assessed valued activities, activity type, activity restriction due to MI, and replacement of restricted activities. Motivation and confidence to quit smoking, number of cigarettes per day, and mood were also assessed. Analysis was performed with generalized linear (or logistic) regression models adjusted for age and physical functioning using aggregated data at baseline. RESULTS: Greater number and frequency of valued activities was associated with less smoking, depression, negative affect, and stress and higher positive affect and self-efficacy to quit. Activity restriction was associated with greater odds of major depression, and activity replacement with lower odds of major depression, lower stress, and higher positive affect and self-efficacy. Strength of associations varied by activity type. CONCLUSIONS: Consistent with our theoretical model, BA activity constructs were associated with several mediators of smoking outcomes in the expected directions. Smokers engaging in valued activities have more favorable profiles for smoking cessation and mood management.

A randomized trial examining the effect of yoga on dietary lapses and lapse triggers following behavioral weight loss treatment.

Background: Dietary lapses can hinder weight loss and yoga can improve self-regulation, which may protect against lapses. This study examined the effect of yoga on dietary lapses, potential lapse triggers (e.g., affective states, cravings, dietary temptations), and reasons for initiating eating following weight loss treatment. Methods: Sixty women with overweight/obesity (34.3 ± 3.9 kg/m2) were randomized to a 12 week yoga intervention (2x/week; YOGA) or contact-matched control (cooking/nutrition classes; CON) following a 12-week behavioral weight loss program. Participants responded to smartphone surveys (5x/day) over a 10-day period at baseline, 12, and 24 weeks to assess lapses and triggers. Results: At 24 weeks, YOGA and CON differed on several types of lapses (i.e., less eating past full, eating more than usual, loss of control when eating, self-identified overeating, difficulty stopping eating in YOGA), and YOGA was less likely to eat to feel better or in response to stress (ps < 0.05). YOGA also reported less stress and anxiety and more positive affect (ps < 0.01); dietary temptations and cravings did not differ from CON. Conclusion: Yoga resulted in fewer dietary lapses and improved affect among women with overweight/obesity following weight loss. While preliminary, findings suggest that yoga should be considered as a potential component of weight loss treatment to target dietary lapses.

Integrated smoking cessation and mood management following acute coronary syndrome: Protocol for the post-acute cardiac event smoking (PACES) trial.

BACKGROUND: Approximately 400,000 people who smoke cigarettes survive Acute Coronary Syndrome (ACS; unstable angina, ST and non-ST elevation myocardial infarction) each year in the US. Continued smoking following ACS is an independent predictor of mortality. Depressed mood post-ACS is also predictive of mortality, and smokers with depressed mood are less likely to abstain from smoking following an ACS. A single, integrated treatment targeting depressed mood and smoking could be effective in reducing post-ACS mortality. METHOD/DESIGN: The overall aim of the current study is to conduct a fully powered efficacy trial enrolling 324 smokers with ACS and randomizing them to 12 weeks of an integrated smoking cessation and mood management treatment [Behavioral Activation Treatment for Cardiac Smokers (BAT-CS)] or control (smoking cessation and general health education). Both groups will be offered 8 weeks of the nicotine patch if medically cleared. Counseling in both arms will be provided by tobacco treatment specialists. Follow-up assessments will be conducted at end-of-treatment (12-weeks) and 6, 9, and 12 months after hospital discharge. We will track major adverse cardiac events and all-cause mortality for 36 months post-discharge. Primary outcomes are depressed mood and biochemically validated 7-day point prevalence abstinence from smoking over 12 months. DISCUSSION: Results of this study will inform smoking cessation treatments post-ACS and provide unique data on the impact of depressed mood on success of post-ACS health behavior change attempts.

A preliminary investigation of yoga as an intervention approach for improving long-term weight loss: A randomized trial.

OBJECTIVE: Yoga targets psychological processes which may be important for long-term weight loss (WL). This study is the first to examine the feasibility, acceptability, and preliminary efficacy of yoga within a weight management program following WL treatment. METHODS: 60 women with overweight or obesity (34.3±3.9 kg/m2, 48.1±10.1 years) were randomized to receive a 12-week yoga intervention (2x/week; YOGA) or a structurally equivalent control (cooking/nutrition classes; CON), following a 3-month behavioral WL program. Feasibility (attendance, adherence, retention) and acceptability (program satisfaction ratings) were assessed. Treatment groups were compared on weight change, mindfulness, distress tolerance, stress, affect, and self-compassion at 6 months. Initial WL (3-mo WL) was evaluated as a potential moderator. RESULTS: Attendance, retention, and program satisfaction ratings of yoga were high. Treatment groups did not differ on WL or psychological constructs (with exception of one mindfulness subscale) at 6 months. However, among those with high initial WL (≥5%), YOGA lost significantly more weight (-9.0kg vs. -6.7kg) at 6 months and resulted in greater distress tolerance, mindfulness, and self-compassion and lower negative affect, compared to CON. CONCLUSIONS: Study findings provide preliminary support for yoga as a potential strategy for improving long-term WL among those losing ≥5% in standard behavioral treatment.
