Relationship of alcohol use and facial flushing to blood pressure and HbA1c among Cambodian populations with dysglycemia in the U.S. and in Cambodia.

BACKGROUND AND AIMS: Facial flushing after drinking alcohol, common among Asians, is a phenotype for genes involved in alcohol metabolism. METHODS: We investigated cross-sectional associations between flushing, alcohol use, blood pressure (BP) and HbA1c among (n = 287) Cambodians with dysglycemia in Cambodia and in the U.S. Participants were categorized as Abstainers, Flushers who drink, or Non-flushers who drink. RESULTS: Flushers and Non-flushers had similar alcohol use. Flushers had higher BP than Non-flushers and Abstainers, even after controlling for confounders. Findings were similar across countries. Drinkers had higher HbA1c than Abstainers. CONCLUSIONS: Future research should examine whether reducing alcohol improves cardiometabolic outcomes.

Comparing the reinforcing value of high intensity interval training versus moderate intensity aerobic exercise in sedentary adults.

Exercise is a reinforcer for both animals and humans, as they will work progressively harder to gain access for the opportunity to exercise. Exercise activates brain reward pathways similar to drugs of abuse, and the magnitude of the reinforcing value of exercise is a predictor of exercise behavior. The majority of research on exercise reinforcement has studied moderate intensity aerobic exercise (MIAE) or resistance training. There is limited research on the relative reinforcing value (RRV) of high intensity interval training (HIIT), which is often reported to be a preferred form of exercise in comparison to MIAE. Experiment 1 was a pilot study of 20 sedentary females designed to compare the reliability of differences in RRVHIIT vs RRVMIAE over two sessions, assess protocols comparing different volumes of HIIT in comparison to MIAE, and estimate sample sizes needed for a fully powered study to assess which type of exercise protocol was a better substitute for a highly liked sedentary activity. Experiment 2 studied 44 participants to assess whether HIIT or MIAE would be better substitutes for highly liked sedentary activities. Experiment 1 showed that measures of RRVHIIT or RRVMIAE were reliable, and that volume of HIIT did not influence RRVHIIT, even if it was of equal amount or duration to MIAE. Experiment 2 showed that HIIT was a more preferred substitute for sedentary behaviors than MIAE. Predictors of RRVMIAE were liking of MIAE and pleasantness of affect post MIAE. These results suggest inactive people may find interval training to be more reinforcing than MIAE, and may be more likely to adopt and maintain an exercise program involving HIIT rather than MIAE. The next stage of research should be to understand how to sensitize the RRV of exercise to motivate sedentary people to be more active.

Mothers' DASH diet adherence and food purchases after week-long episodic future thinking intervention.

Prospection has helped participants forego the temptation to buy and eat higher calorie nutrient poor foods in favor of buying and eating fewer calories and healthier macronutrient profiles in laboratory tasks and brief field studies. This pilot study examines whether episodic future thinking (EFT) improves mothers' dietary behavior and food purchasing over a longer 7-10-day period. The study utilized a 2 × 2 factorial design with mothers (N = 60) randomized to EFT or standardized episodic thinking (SET) crossed with dietary approaches to stop hypertension (DASH) diet education or a food safety education control. Participants listened to their cues (e.g., recordings of themselves imagining a future event or recalling a past episode) using a mobile ecological momentary intervention (EMI) tool and returned to complete a follow-up dietary recall and submit food receipts. Results showed diets of mothers in the EFT groups became more concordant with the DASH diet (ηp2 = 0.08, p < .05) than mothers in the SET group. When considering food purchases for the family, there was an EFT effect on milligrams of sodium purchased (ηp2 = 0.07, p < .05) and a trend towards a decrease in grams of fat purchased (ηp2 = 0.06, p = .06), however, these findings were no longer significant after correcting for multiple comparisons. There were no DASH education effects and no DASH by EFT interactions observed. The dietary intake and food purchasing results should be replicated in larger more representative samples.

An ecological momentary episodic future thinking intervention on mother's weekly food purchases.

BACKGROUND: Imagining one's own future (episodic future thinking, EFT) has helped mothers with overweight purchase healthier groceries during an online shopping task in the laboratory. The present study explored whether delivering an EFT intervention to participants' devices via an ecological momentary intervention (EMI) tool would help mothers purchase healthier food at brick-and-mortar stores. METHOD: Participants (N = 43, mothers 31-52 years of age, BMI ≥ 24.9 kg/m2) were randomized to EFT or standardized episodic thinking (SET). EFT cues include a positive and vivid description of future events while SET cues focus on the recent experience of playing games in the laboratory. Cues were uploaded to participant profiles on an EMI site. Participants were trained on how to read and listen to cues as well as how to detail purchases. Participants received text reminders to listen to cues before shopping and returned with receipts the following day. Receipt data was analyzed to derive dependent variables, calories, and nutrients purchased per person. Correlations were used to analyze associations between study variables of interest, and ANOVAs were conducted to compare dietary variables by group. RESULTS: Participants in the EFT group purchased fewer calories, fewer grams of fat, fewer grams of saturated fat, and fewer miligrams of sodium than participants in the SET control group. CONCLUSION: Delivering EFT cues to participant devices may be a promising way to improve the calorie and nutrient content of food purchases. Future research should include a longer follow-up and analyze calorie changes over time. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Improvements in episodic future thinking methodology: Establishing a standardized episodic thinking control.

OBJECTIVE: Delay discounting (DD) is the choice of a smaller immediate reward over a larger delayed reward, which has been associated with a number of maladaptive behaviors. Episodic future thinking (EFT), the ability to project oneself into the future, is an intervention designed to reduce DD. EFT has reliable effects on DD, but the size of the effect varies, which could be due in part to the use of different control groups. Episodic recent thinking (ERT) serves as a common control for many EFT studies, but the temporal window of "recent" cues ranges from 24 hours ago to 12 days past. Since prior research has shown that retrospection can lead to prospection, it may be important to ensure that EFT controls do not inadvertently lead to prospection for some participants thereby increasing the variability of the control condition. The present study sought to develop a comparison group that standardizes the time frame and experiences that are the basis for the recent thinking control. METHODS: Participants (n = 53, 18-45) were randomized to one of three conditions: EFT, ERT, or standardized episodic thinking (SET). Participants attended a laboratory appointment where they played mobile application games, created cues, and completed a DD task. RESULTS: There was a significant difference between groups (p<0.05), with EFT reducing discounting more than either control (p<0.05), and no differences between ERT and SET (p>0.05). CONCLUSION: This study established that SET provides an alternative control in EFT studies and provides the advantage of standardizing the participant's recent experience without changing the relationship between EFT and recent thinking controls.

Do process simulations during episodic future thinking enhance the reduction of delay discounting for middle income participants and those living in poverty?

Two studies examined whether episodic future thinking (EFT; pre-experiencing future events) reduces discounting of future rewards (DD). No studies have investigated whether process simulations (i.e., simulating the process of executing a future event) amplify EFT's reduction of DD. Study 1 examined the effect of incorporating process simulations into EFT (N = 42, M age = 43.27; 91% female, family income = $75,976) using a 2 × 2 factorial design with type of episodic thinking (process, nonprocess/general) and temporal perspective (EFT, episodic recent thinking) as between-subjects factors. Study 2 replicated Study 1 in a sample of adults living in poverty (N = 36; M age = 38.44, 88% female; family income = $25,625). The results of both studies showed EFT reduced DD, but process-oriented EFT did not amplify the effect of EFT. Our findings suggest the key ingredient in EFT's effect on DD is self-projection into the future. This was also the first study to show EFT improves DD in a sample living in poverty.

Episodic future thinking and grocery shopping online.

Grocery shopping shapes the home food environment, which can contribute to the development of obesity. Episodic future thinking (EFT) helps adults make healthier decisions by initiating prospective thinking, which guides one to forego smaller immediate rewards in favor of larger delayed rewards. EFT could help parents improve grocery purchases thereby improving the home food environment and family eating behaviors. The effect of EFT on food shopping was evaluated in two studies with mothers who were overweight/obese and primary household shoppers. In Study 1, 24 mothers were randomized to goal-directed process EFT versus a money saving control. In Study 2, 33 mothers were randomized to goal-directed process EFT, general EFT, or an episodic recent thinking (ERT) control. Following cue generation, participants completed a task where they purchased one week of groceries from an online store. Food purchases were analyzed for calories purchased per family member. In Study 1 the goal-directed process EFT group purchased fewer calories per person (F(1, 23) = 25.16, p < .001; ηp2 = 0.522). In Study 2 the goal-directed process EFT purchased fewer calories (F(1, 30) = 5.98, p = .02; ηp2 = 0.166) than the ERT control as did the EFT general group (F(1, 30) = 4.61, p = .04; ηp2 = 0.133). The two EFT groups did not differ from each other (F(1, 30) = 0.16, p = .69; ηp2 = 0.005). EFT may be an effective intervention for reducing the energy intake of foods purchased while grocery shopping.

Smartphones are more reinforcing than food for students.

College students engage in high-frequency smartphone use, despite potential negative consequences. One way to conceptualize this behavior is to consider it a highly reinforcing activity. Comparing motivation for smartphones to a powerful primary reinforcer, such as food, can establish their relative reinforcing value. This study investigated whether smartphones were more reinforcing than food, as well as the relationships between smartphone reinforcement, texting use, and smartphone motives. Participants were 76 college students (50% female, Mage = 18.9, SD = 0.99) who had no access to food for three hours and to their smartphones for two hours. After this modest deprivation period, participants worked for time to use their smartphones and 100-cal portions of their favorite snack food concurrently, with the work to obtain portions of both commodities increasing. The amount of smartphone use earned during the task was manipulated across groups (20, 30, 60, 120 s) to establish what amount of smartphone use was needed to motivate responding. Additionally, reinforcing efficacy of smartphones and food using a hypothetical purchase task and motivations for smartphone use was collected. Smartphones were more reinforcing than food using either measurement methodology (p's < 0.001). Smartphone reinforcement predicted number of text messages, controlling for age, sex, and family income. Positive smartphone use motives were associated with reinforcing efficacy of smartphones. These data show that smartphones are potent reinforcers, and are more reinforcing than food given modest food deprivation. These methods provide one important reason why people may use smartphones.

Mix and Match: An Investigation into Whether Episodic Future Thinking Cues Need to Match Discounting Delays in Order to Be Effective.

Episodic future thinking (EFT), or prospectively imagining yourself in the future, has been developed into an intervention tool to reduce delay discounting (DD), or the preference for smaller immediate over larger future rewards, and to make healthier choices that promote long-term health rather than short-term enjoyment. Most EFT interventions use EFT cues whose future events match the time delays of the DD task, which may limit the utility of EFT. The current study (N = 160, Mage = 35.25, 47.5% female) used a 2 × 2 factorial design with type of episodic thinking (matched, unmatched) and temporal perspective (EFT, episodic recent thinking (ERT)) as between-subject factors to investigate whether there were differences in DD for groups that had EFT cues matched to the time delays of the DD task in comparison to cues with unmatched temporal delays. The results showed EFT reduced DD compared to ERT controls, and no differences emerged between matched and unmatched EFT groups. Our findings suggest that either the process of generating EFT cues or the use of any positive and vivid future event, regardless of whether it is matched to the DD task, can reduce DD.

Drinking and exercise behaviors among college students: between and within-person associations.

Prior work has suggested a paradoxical positive relationship between the risk behavior alcohol use and the health behavior exercise, particularly in young adults. Though seldom tested, different theoretical perspectives exist on the mechanisms that may explain the positive relationship. The aims of this study were to test theorized mechanisms of association, including common causes shared by both behaviors (e.g., personality, motives, affective), compensatory processes such as exercising to compensate for calories from alcohol consumption, and methodological confounds (e.g., between vs. within subject effects) in a college sample (N = 132; 56.3% male; 76% Caucasian; M age = 19.15, SD = 0.99) using a cross-sectional design and time line follow back methods. A positive, between-subjects association between alcohol and exercise was found and explained by exercising to compensate for calories of alcohol consumption, enhancement motives, and physical activity enjoyment. However, we also observed a significant and negative within-subjects association between the two constructs, suggesting that, on a given day, individuals who exercise more tended to drink less. Furthermore, individuals who exercised more during the week tended to have declines in weekend drinking over time. Results suggest a complex relationship between exercise and alcohol use among young adults, and highlight the importance of distinguishing between and within subject processes, as well as the temporal ordering of the two behaviors. Implications are discussed in regard to theory, prevention, and intervention.

Does goal relevant episodic future thinking amplify the effect on delay discounting?

Delay discounting (DD) is the preference for smaller immediate rewards over larger delayed rewards. Research shows episodic future thinking (EFT), or mentally simulating future experiences, reframes the choice between small immediate and larger delayed rewards, and can reduce DD. Only general EFT has been studied, whereby people reframe decisions in terms of non-goal related future events. Since future thinking is often goal-oriented and leads to greater activation of brain regions involved in prospection, goal-oriented EFT may be associated with greater reductions in DD than general goal-unrelated EFT. The present study (n=104, Mage=22.25, SD=3.42; 50% Female) used a between-subjects 2×2 factorial design with type of episodic thinking (Goal, General) and temporal perspective (Episodic future versus recent thinking; EFT vs ERT) as between factors. Results showed a significant reduction in DD for EFT groups (p<0.001, Cohen's d effect size=0.89), and goal-EFT was more effective than general-EFT on reducing DD (p=0.03, d=0.64).

The Effects of Coaching Patients to List Questions Before Visiting Cancer Specialists: Retrospective Evaluation of Visit Preparation in a Rural, Underserved Setting.

BACKGROUND: A community-based organization implemented an evidence-based intervention to help rural cancer patients list questions before oncology visits. OBJECTIVE: Was the question-listing intervention effective in reducing anxiety and increasing decision self-efficacy? METHODS: The organization surveyed patients on decision self-efficacy (273 respondents, 99% response rate) and anxiety (190, 68%) before and after question-listing interventions delivered from 2006 - 2011. We analyzed responses using two-sided paired t-tests at 5% significance and conducted linear regression to identify significant predictors of change. We examined predictors related to the patient (location, demographics, disease status and baseline decision self-efficacy and anxiety); the intervention (including interventionist case volume); and the visit (including type of doctor seen). RESULTS: Question-listing was associated with higher mean decision self-efficacy (2.70/3.43 pre/post, 1-4 min-max, P<.001) and lower mean anxiety (7.26/5.87, 1-10 min-max, P<.001). Significant predictors of change in decision self-efficacy included: patient location; interventionist case volume; baseline decision self-efficacy and anxiety. Higher baseline anxiety was also associated with reductions in anxiety. CONCLUSIONS: In a sustained community-based implementation, the intervention helped patients prepare for oncology visits. Patients reported higher self-efficacy and lower anxiety.

Decision support by telephone: randomized controlled trial in a rural community setting.

OBJECTIVE: Our community-based participatory research partnership previously evaluated Consultation Planning (CP), a question-listing intervention delivered in-person. We now report on effectiveness, cost, and value of delivering CP by telephone (Tele-CP). METHODS: Between 2007 and 2010, we randomly assigned rural women with a diagnosis of breast cancer to receive Tele-CP or In-Person CP. We compared ratings of decision self-efficacy (0 minimum to 4 maximum) with a pre-specified non-inferiority margin of 15%. We also explored psychosocial and economic outcomes. RESULTS: Tele-CP (n=35) recipients reported mean decision self-efficacy ratings of 3.53 versus 3.44 for in-person (n=32). Under intent-to-treat analysis, we rejected the null hypothesis of greater than 0.52 inferiority for Tele-CP (95% CI for difference: -0.44 to 0.13, p=0.006). The intervention costs averaged $48 for Tele-CP versus $78 in-person (95% CI for difference: -$63 to $2). Mean willingness-to-pay was $154 for Tele-CP and $144 for in-person (95% CI for difference: -$88 to $108). CONCLUSION: Tele-CP was non-inferior to In-Person CP, cost no more, and was equally valued by patients. PRACTICE IMPLICATIONS: Telephone delivery of Consultation Planning can achieve comparable quality, cost, and value as in-person. Organizations offering Consultation Planning or similar question-listing interventions should consider adopting telephone delivery.

Using the critical incident technique in community-based participatory research: a case study.

BACKGROUND: Successful community-based participatory research involves the community partner in every step of the research process. The primary study for this paper took place in rural, Northern California. Collaborative partners included an academic researcher and two community based resource centers that provide supportive services to people diagnosed with cancer. OBJECTIVES: This paper describes our use of the Critical Incident Technique (CIT) to conduct Community-based Participatory Research. We ask: Did the CIT facilitate or impede the active engagement of the community in all steps of the study process? METHODS: We identified factors about the Critical Incident Technique that were either barriers or facilitators to involving the community partner in every step of the research process. CONCLUSIONS: Facilitators included the CIT's ability to accommodate involvement from a large spectrum of the community, its flexible design, and its personal approach. Barriers to community engagement included training required to conduct interviews, depth of interview probes, and time required. Overall, our academic-community partners felt that our use of the CIT facilitated community involvement in our Community-Based Participatory Research Project, where we used it to formally document the forces promoting and inhibiting successful achievement of community aims.

Consultation support for rural women with breast cancer: results of a community-based participatory research study.

OBJECTIVE: This study asked: (1) What do rural women with breast cancer need to make the most out of their major medical appointments? and (2) What can the community resource centers do to best support those needs? METHODS: We interviewed 12 doctors, 12 breast cancer survivors and 10 community agency staff, including those who provide services to Latinos and Native Americans. Interviews generated success factors and barriers related to meeting patient information needs. Examples were categorized into themes. RESULTS: Success factors included making sure patients review high quality educational materials before the visit; and that someone is available to take notes. Doctors felt that a patient list of questions was productive, but some survivors felt doctors did not always respond productively to the list. Respondents did not mention audiorecording unless prompted. Most then endorsed it. CONCLUSION: Educational materials, question lists, and note-takers can help rural women with breast cancer and their doctors achieve their goals during treatment discussions. Audiorecording may be an implicit but not explicit need. PRACTICE IMPLICATIONS: Other cancer resource centers and support agencies should consider offering information, question-listing, and note-taking services. They should assess whether audiorecording is an implicit need in their settings.

Adaptation of consultation planning for Native American and Latina women with breast cancer.

CONTEXT: Resource centers in rural, underserved areas are implementing Consultation Planning (CP) to help women with breast cancer create a question list before a doctor visit. PURPOSE: To identify changes needed for acceptable delivery of CP to rural Native Americans and Latinas. METHODS: We interviewed and surveyed 27 Native American and Latino key informants. We coded interviews thematically, and calculated summary statistics for the survey data. FINDINGS: Native American and Latino respondents endorsed CP as culturally acceptable to their communities, while suggesting changes. Respondents also raised the topic of how to further support patients once they have successfully prepared a question list using CP. CONCLUSIONS: The resource centers implemented the requested changes.
