RESUMO
BACKGROUND: Co-use of nicotine, alcohol and/or cannabis is common among adults in the United States. Co-use may represent greater addiction severity than single substance use. Recent studies have examined the extent to which the frequency, order, simultaneity, motivations, and contextual factors associated with co-use differ from that of single use. Co-use has become prevalent among racial/ethnic minority individuals who exhibit distinct co-use patterns and related outcomes; however, most of these studies rely on cross-sectional or sparse longitudinal observations. Ecological momentary assessment (EMA) can illuminate such patterns and associations with time-varying contexts. This review summarizes EMA studies on co-use published from 2008 to 2023 involving racial/ethnic minority individuals and point to gaps. Our review addresses: 1) whether use of one substance leads to substitution or complementary use of another, 2) whether antecedents/contexts differ by co-use patterns and minority status, and 3) what consequences of co-use have been documented across co-use patterns or minority status. METHODS: Search results yielded 465 articles, with 33 meeting inclusion criteria. We extracted study-level characteristics and synthesized the findings. RESULTS: The findings largely focused on co-use patterns, categories of co-use, proximal antecedents and contexts, and consequences. Variations by minority status were rarely examined; few examined acute effects of unique experiences that may contribute to co-use among racial/ethnic minority adults. CONCLUSIONS: The EMA literature on co-use is burgeoning in recent years and supports complementary hypothesis. More research to capture time-intensive data on experiences to contextualize the co-use among racial/ethnic minority groups with greater diversity in race/ethnicity is warranted.

Functional inhibition is known to improve treatment outcomes in substance use disorder (SUD), potentially through craving management enabled by underlying cerebral integrity. Whereas treatment is challenged by a multitude of substances that patients often use, no study has yet unraveled if inhibition and related cerebral integrity could prevent relapse from multiples substances, that is, one's primary drug of choice and secondary ones. Individuals with primary alcohol, cannabis, or tobacco use disorders completed intensive Ecological Momentary Assessment (EMA) coupled with resting-state functional MRI (rs-fMRI) to characterize the extent to which inhibition and cerebral substrates interact with craving and use of primary and any substances. Participants were 64 patients with SUD and 35 healthy controls who completed one week EMA using Smartphones to report 5 times daily their craving intensity and substance use and to complete Stroop inhibition testing twice daily. Subsamples of 40 patients with SUD and 34 control individuals underwent rs-fMRI. Mixed Model Analysis revealed that reported use of any substance by SUD individuals predicted later use of any and primary substance, whereas use of the primary substance only predicted higher use of that same substances. Craving and inhibition level independently predicted later use but did not significantly interact. Preserved inhibition performance additionally influenced use indirectly by mediating the link between subsequent uses and by being linked to rs-fMRI connectivity strength in fronto-frontal and cerebello-occipital connections. As hypothesized, preserved inhibition performance, reinforced by the integrity of inhibitory neurofunctional substrates, may partake in breaking an unhealthy substance use pattern for a primary substance but may not generalize to non-target substances or to craving management.

BACKGROUND: Affect states are posited to play a pivotal role in addiction-related processes, including tobacco lapse (i.e., smoking during a quit attempt), and distinct affective states (e.g., joy vs. happiness) may differentially influence lapse likelihood. However, few studies have examined the influence of distinct affective states on tobacco lapse. PURPOSE: This study examines the influence of 23 distinct affect states on tobacco lapse among a sample of tobacco users attempting to quit. METHODS: Participants were 220 adults who identified as African American (50% female, ages 18-74). Ecological momentary assessment was used to assess affect and lapse in real-time. Between and within-person associations testing links between distinct affect states and lapse were examined with multilevel modeling for binary outcomes. RESULTS: After adjusting for previous time's lapse and for all other positive or negative affect items, results suggested that at the between-person level, joy was associated with lower odds of lapse, and at the within-person level, attentiveness was associated with lower odds of lapse. Results also suggested that at the between-person level, guilt and nervous were associated with higher odds of lapse, and at the within-person level, shame was associated with higher odds of lapse. CONCLUSIONS: The present study uses real-time, real-world data to demonstrate the role of distinct positive and negative affects on momentary tobacco lapse. This work helps elucidate specific affective experiences that facilitate or hinder the ability to abstain from tobacco use during a quit attempt.

Substance use disorders are characterized by inhibition deficits related to disrupted connectivity in white matter pathways, leading via interaction to difficulties in resisting substance use. By combining neuroimaging with smartphone-based ecological momentary assessment (EMA), we questioned how biomarkers moderate inhibition deficits to predict use. Thus, we aimed to assess white matter integrity interaction with everyday inhibition deficits and related resting-state network connectivity to identify multi-dimensional predictors of substance use. Thirty-eight patients treated for alcohol, cannabis or tobacco use disorder completed 1 week of EMA to report substance use five times and complete Stroop inhibition testing twice daily. Before EMA tracking, participants underwent resting state functional MRI and diffusion tensor imaging (DTI) scanning. Regression analyses were conducted between mean Stroop performances and whole-brain fractional anisotropy (FA) in white matter. Moderation testing was conducted between mean FA within significant clusters as moderator and the link between momentary Stroop performance and use as outcome. Predictions between FA and resting-state connectivity strength in known inhibition-related networks were assessed using mixed modelling. Higher FA values in the anterior corpus callosum and bilateral anterior corona radiata predicted higher mean Stroop performance during the EMA week and stronger functional connectivity in occipital-frontal-cerebellar regions. Integrity in these regions moderated the link between inhibitory control and substance use, whereby stronger inhibition was predictive of the lowest probability of use for the highest FA values. In conclusion, compromised white matter structural integrity in anterior brain systems appears to underlie impairment in inhibitory control functional networks and compromised ability to refrain from substance use.

INTRODUCTION: Fatigue is prevalent across a wide range of medical conditions and can be debilitating and distressing. It is likely that fatigue is experienced differently according to the underlying aetiology, but this is poorly understood. Digital health technologies present a promising approach to give new insights into fatigue.The aim of this study is to use digital health technologies, real-time self-reports and qualitative interview data to investigate how fatigue is experienced over time in participants with myeloma, long COVID, heart failure and in controls without problematic fatigue. Objectives are to understand which sensed parameters add value to the characterisation of fatigue and to determine whether study processes are feasible, acceptable and scalable. METHODS AND ANALYSIS: An ecological momentary assessment study will be carried out over 2 or 4 weeks (participant defined). Individuals with fatigue relating to myeloma (n=10), heart failure (n=10), long COVID (n=10) and controls without problematic fatigue or a study condition (n=10) will be recruited. ECG patches will measure heart rate variability, respiratory rate, body temperature, activity and posture. A wearable bracelet accompanied by environment beacons will measure physical activity, sleep and room location within the home. Self-reports of mental and physical fatigue will be collected via smartphone app four times daily and on-demand. Validated fatigue and affect questionnaires will be completed at baseline and at 2 weeks. End-of-study interviews will investigate experiences of fatigue and study participation. A feedback session will be offered to participants to discuss their data.Data will be analysed using multilevel modelling and machine learning. Interviews and feedback sessions will be analysed using content or thematic analyses. ETHICS AND DISSEMINATION: This study was approved by the East of England-Cambridge East Research Ethics Committee (22/EE/0261). The results will be disseminated in peer-reviewed journals and at international conferences. TRIAL REGISTRATION NUMBER: NCT05622669.

BACKGROUND: Opioids are a common and essential treatment for acute sickle cell disease (SCD) pain. However, opioids carry well-known adverse side effects, including potential development of hyperalgesia and nociplastic pain. We characterized opioid use in youth with SCD using ecological momentary assessment (EMA) data, and investigated the relationships between home-based opioid use, pain, and a range of biopsychosocial factors. METHOD: Eighty-eight youth with SCD (aged 8-17 years) completed EMAs assessing home-based opioid use, pain, and related factors. Analyses consisted of descriptive and multilevel logistic regression to predict daily home opioid use. RESULTS: Youth averaged 3.64 weeks of EMAs. Approximately 35% of the sample (n = 31) took an opioid during the EMA period, and used them on only 24% of reported pain days. Youth who took opioids reported a higher percentage of pain days (t = -2.67, p < .05) and mean pain severity scores (t = -2.30, p < .05) than youth who did not take opioids. Multilevel logistic regression analyses indicated that high daily pain severity (odds ratio [OR] = 1.02, p < .01), older age (OR = 1.324, p < .01), and low positive affect (OR = 0.91, p < .01) were each related to an increased likelihood of opioid use. CONCLUSION: Youth with SCD take opioids appropriately in response to their pain, based on daily self-report. Beyond daily pain severity, age, and daily variation in positive affect were related to home-based opioid use. This suggests that behavioral interventions that enhance positive affect may promote reduced opioid use among youth with SCD.

Introduction: Ureteral stents can cause significant patient discomfort, yet the temporal dynamics and impact on activities remain poorly characterized. We employed an automated tool to collect daily ecological momentary assessments (EMAs) regarding pain and the ability to work following ureteroscopy with stenting. Our aims were to assess feasibility and better characterize the postoperative patient experience. Materials and Methods: As an exploratory endpoint within an ongoing clinical trial, patients undergoing ureteroscopy with stenting were asked to complete daily EMAs for 10 days postoperatively or until the stent was removed. Questionnaires were distributed through text messages and included a pain scale (0-10) and a single item from the validated Patient-Reported Outcomes Measurement Information System Ability to Participate in Social Roles and Activities instrument, as well as days missed from work or school. Results: Among the first 65 trial participants, 59 completed at least 1 EMA (overall response rate 91%). Response rates were >85% for each time point through postoperative day (POD)10. Median respondent age was 58 years (interquartile range [IQR] 50-67), and 56% were female. Stones were 54% renal and 46% ureteral, with a median diameter of 9 mm (IQR 7-10). Median stent dwell time was 7 days (IQR 6-8). Pain scores were highest on POD1 (median score 4) and declined on each subsequent day, reaching a median score of 2 on POD5. Sixty-three percent of patients on POD1 reported that they had trouble performing their usual work at least sometimes, but by POD5, this was <50% of patients. Patients who work or attend school reported a median of 1 day missed (IQR 0-2). Conclusions: An automated daily EMA system for capturing patient-reported outcomes was demonstrated to be feasible with sustained excellent engagement. Patients with stents reported the worst pain and interference with work on POD1, with steady improvements thereafter, and by POD5, the majority of patients had minimal pain or trouble performing their usual work. This work is associated with a registered clinical trial [NCT05026710].

INTRODUCTION: People with advanced cancer can experience a wide range of multidimensional symptoms or concerns, but little is known about when and how these fluctuate in daily life. Experience sampling methods (ESMs) involve repeated self-reports in people's natural contexts aimed at uncovering everyday life experiences. ESM has limited recall bias and good ecological validity but might be burdensome to patients. This study aims to pretest and evaluate the feasibility and clinical utility of a validated ESM and use it to explore everyday experiences of people living with advanced breast or lung cancer. METHODS AND ANALYSIS: In step 1, we will optimise our ESM method by pretesting it through usability interviews and a pilot ESM study. In step 2, we will evaluate and use the ESM method through an observational ESM study to investigate the daily experiences of people with advanced breast or lung cancer. Step 2 also includes interviews with healthcare professionals to determine the clinical utility of ESM in oncology. Participants will complete a digital questionnaire ten times per day, measuring momentary experiences in the physical, psychological, social, spiritual-existential domains and context. Multilevel regression models will analyse fluctuations and temporal relations among measured experiences and context. Analyses also include evaluation of compliance and participation rates. We will apply content analysis to the usability interviews and follow-up interviews of the pilot ESM study. ETHICS AND DISSEMINATION: We obtained approval from the ethics committees of the University Hospitals of Brussels (BUN: 1432023000043) and Ghent (ONZ-2023-0136). Results will be published in open-access, peer-reviewed journals and presented at conferences. If ESM appears feasible in this population, it could offer new insights into the daily experiences and help optimise support for people with advanced cancer.

Background: Ecological momentary assessment (EMA) is an increasingly used tool for data collection in behavioral research, including smoking cessation studies. As previous addiction research suggests, EMA has the potential to elicit cue reactivity by triggering craving and increasing behavioral awareness. However, there has been limited evaluation of its potential influence on behavior. Objective: By examining the perspectives of research participants enrolled in a tobacco treatment intervention trial, this qualitative analysis aims to understand the potential impact that EMA use may have had on smoking behaviors that may not have otherwise been captured through other study measures. Methods: We performed a qualitative analysis of in-depth interviews with participants enrolled in a pilot randomized controlled trial of a tobacco treatment intervention that used SMS text messaging to collect EMA data on smoking behaviors. In the pilot randomized controlled trial, combustible cigarette and e-cigarette use and smoking-related cravings were measured as part of an EMA protocol, in which SMS text messaging served as a smoking diary. SMS text messaging was intended for data collection only and not designed to serve as part of the intervention. After a baseline assessment, participants were asked to record daily nicotine use for 12 weeks by responding to text message prompts that they received 4 times per day. Participants were prompted to share their experiences with the EMA text messaging component of the trial but were not directly asked about the influence of EMA on their behaviors. Transcripts were coded according to the principles of the framework for applied research. The codes were then examined, summarized, and grouped into themes based on the principles of grounded theory. Results: Interviews were analyzed for 26 participants. The themes developed from the analysis suggested the potential for EMA, in the form of an SMS text messaging smoking diary, to influence participants' smoking behaviors. The perceived impacts of EMA text messaging on smoking behaviors were polarized; some participants emphasized the positive impacts of text messages on their efforts to reduce smoking, while others stressed the ways that text messaging negatively impacted their smoking reduction efforts. These contrasting experiences were captured by themes reflecting the positive impacts on smoking behaviors, including increased awareness of smoking behaviors and a sense of accountability, and the negative impacts on emotions and smoking behaviors, including provoking a sense of guilt and triggering smoking behaviors. Conclusions: The collection of EMA smoking behavior data via SMS text messaging may influence the behaviors and perceptions of participants in tobacco treatment interventions. More research is needed to determine the magnitude of impact and mechanisms, to account for the potential effects of EMA. A broader discussion of the unintended effects introduced by EMA use is warranted among the research community.

OBJECTIVE: To investigate the relation between accelerometer-measured physical activity and real-time pain in individuals with femoroacetabular impingement syndrome (FAIS). We tested the hypothesis that increased duration of high intensity activity would contribute to momentary increases in pain. DESIGN: Observational study. SETTING: Participants' natural, day-to-day environment. PARTICIPANTS: Population-based sample of 33 individuals with unilateral FAIS. Important eligibility criteria included no concomitant hip disorders or previous hip surgery. Key sociodemographic features include that all participants were required to have a smartphone. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Duration and intensity of physical activity as measured by a waist-worn accelerometer, and instantaneous pain reported in real-time smartphone-based ecological momentary assessment surveys. Physical activity variables included each person's average sedentary time, light physical activity (LPA), and moderate to vigorous physical activity (MVPA) in the 90 minutes proceeding all pain surveys as well as fluctuation in sedentary, LPA, and MVPA above or below average prior to each individual survey. RESULTS: Linear mixed models revealed that the significant predictors of pain included fluctuation in sedentary time (B=-0.031, P<.001), average LPA (B=0.26, P=.035), and the interaction between fluctuation in LPA and fluctuation in MVPA (B=0.001, P<.001). Fluctuation in sedentary time above a person's average was associated with lower pain, while average LPA and fluctuations above average in both LPA and MVPA were associated with higher pain. CONCLUSIONS: These results suggest that individuals with FAIS can engage in health-enhancing MVPA but should focus on avoiding concurrent increase above average in both high intensity and LPA in the same 90-minute period. Future work is warranted testing the efficacy of such an approach on pain. Additionally, given that high levels of LPA may arise from a host of socioeconomic factors, additional research is needed to disentangle the effect of LPA on pain in FAIS.

OBJECTIVE: To understand parent and child perception of spaces experienced during outpatient procedures and to measure their anxiety in these spaces. BACKGROUND: Same-day procedures are becoming prevalent among children in the United States. While studies conducted in different types of healthcare settings show that the physical environment influences healthcare experiences of patients, there is a lack of research on patient and family perceptions of the physical environment of the outpatient centers where such procedures are conducted. METHODS: This study used ecological momentary assessment to collect patient experience and anxiety data at different points during the patient's journey through an ambulatory surgical center where pediatric gastrointestinal (GI) procedures were performed. Objective and subjective measures of anxiety were collected. A Qualtrics survey asked participants' perceptions about four spaces-waiting, preprocedure, procedure, and recovery. RESULTS: Child participants reported liking murals, double chairs, patient beds, wall color, and access to a television. They disliked medical equipment and lack of child-friendly furniture. Most parents liked the murals, access to a television, and nature photos, while disliking the lack of privacy, lack of toys in waiting areas, and lack of child-friendly furniture. On average, both children and parents experienced the highest anxiety levels before and during the procedure and the lowest during recovery. Between the four spaces, no significant differences were observed in the heart rate variability and skin conductance responses for both groups. CONCLUSIONS: Despite the outpatient nature of the procedures, participants experienced anxiety before the GI procedure. Comfortable design features that provide distractions are preferred by children and their parents.

The incentive-sensitization theory (IST) has emerged as a potentially useful theory in explaining substance addiction. IST postulates that the prolonged use of a substance can alter neural systems that are often involved in incentive motivation and reward processes, leading to an increased "sensitization" to the substance and associated stimuli. However, this increased sensitization is thought to mediate only the individual's craving of the substance (e.g., their "wanting"), not their enjoyment of the substance (e.g., their "liking"), a process that may involve unconscious implicit changes in cognitive networks linked to specific substances. Consequently, IST may better explain the real-world dissonance reported for individuals who want to accomplish long-term substance cessation but fail to do so, a phenomenon that is common in adolescent smokers. Thus, the present study aimed to examine the principles of IST in a sample of 154 adolescent ad libitum smokers (Mage = 16.57, SDage = 1.12, 61.14% male) utilizing ecological momentary assessment. Data were analyzed utilizing a multilevel structural equation model examining changes in positive affect (PA), negative affect (NA), and stress from Time 1 (T1) and Time 2 (T2) as a function of smoking and tested the influence of implicit cognition (specifically, implicit attitudes about smoking [Implicit Association Test (IAT)]) on these associations. Consistent with the principles of IST, results found a modest significant negative association between smoking status at T1 and PA at T2 (B = -0.11, p = .047). This association was further moderated by IAT (B = -0.19, p = .029) and was particularly potentiated at high levels of IAT (B = -0.44, p < .001), compared to low (B = -0.05, p = .663) or mean levels of IAT (B = -0.25, p = .004). Findings from this study provide additional support to the principles underlying IST and indicate that, in adolescents, smoking may result in thwarted PA indicative of a transition from "liking" toward "wanting," and this is especially pronounced among those with stronger implicit smoking cognitions.

BACKGROUND: Children with loss of control (LOC) eating and overweight/obesity have relative deficiencies in trait-level working memory (WM), which may limit adaptive responding to intra- and extra-personal cues related to eating. Understanding of how WM performance relates to eating behavior in real-time is currently limited. METHODS: We studied 32 youth (ages 10-17 years) with LOC eating and overweight/obesity (LOC-OW; n = 9), overweight/obesity only (OW; n = 16), and non-overweight status (NW; n = 7). Youth completed spatial and numerical WM tasks requiring varying degrees of cognitive effort and reported on their eating behavior daily for 14 days via smartphone-based ecological momentary assessment. Linear mixed effects models estimated group-level differences in WM performance, as well as associations between contemporaneously completed measures of WM and dysregulated eating. RESULTS: LOC-OW were less accurate on numerical WM tasks compared to OW and NW (ps < .01); groups did not differ on spatial task accuracy (p = .41). Adjusting for between-subject effects (reflecting differences between individuals in their mean WM performance and its association with eating behavior), within-subject effects (reflecting variations in moment-to-moment associations) revealed that more accurate responding on the less demanding numerical WM task, compared to one's own average, was associated with greater overeating severity across the full sample (p = .013). There were no associations between WM performance and LOC eating severity (ps > .05). CONCLUSIONS: Youth with LOC eating and overweight/obesity demonstrated difficulties mentally retaining and manipulating numerical information in daily life, replicating prior laboratory-based research. Overeating may be related to improved WM, regardless of LOC status, but temporality and causality should be further explored. PUBLIC SIGNIFICANCE STATEMENT: Our findings suggest that youth with loss of control eating and overweight/obesity may experience difficulties mentally retaining and manipulating numerical information in daily life relative to their peers with overweight/obesity and normal-weight status, which may contribute to the maintenance of dysregulated eating and/or elevated body weight. However, it is unclear whether these individual differences are related to eating behavior on a moment-to-moment basis.

Ecological Momentary Assessment (EMA) methods are increasingly used by translational scientists to study real-world behavior and experience. The ability to draw meaningful conclusions from EMA research depends upon participant compliance with assessment completion. Most EMA studies provide financial compensation for compliance, but little empirical evidence addresses the impact of reinforcement parameters on the level of compliance. The purpose of this study-within-a-trial was to determine the effects of varying the amount and frequency of reinforcement on EMA compliance in a clinical sample of individuals seeking treatment for cigarette smoking. In the parent clinical trial, participants were asked to complete 9 weeks of EMA (1 daily Morning Assessment and 4 daily Random Assessments). Following a 5-week Standard Payment phase for EMA compliance, 61 individuals seeking treatment for cigarette smoking enrolled in the larger clinical trial were randomized to receive Standard ($1 per assessment, paid biweekly), Frequent ($1 per assessment, paid 3 times per week), or Large ($2 per assessment, paid biweekly) payments for EMA compliance during a 4-week Payment Manipulation Phase. Overall, receiving Frequent or Large payments did not improve EMA compliance compared to Standard payments, Psâ >â .30. Varying frequency and amount of remuneration for EMA compliance did not generally improve compliance in an ongoing clinical trial, raising further questions about the importance of reinforcement parameters in promoting EMA compliance.
Previous studies have addressed the idea that monetary compensation for participation in research is an effective way to encourage individuals to complete the studies. However, there has been limited exploration as whether the amount and frequency of compensation has an influence on participant adherence. We recruited adults who were seeking cigarette smoking treatment and asked them to complete multiple assessments each day on a smartphone app for 9 weeks. Following completion of the assessments, participants were given monetary compensation. A change after 5 weeks led to some persons receiving $1 per assessment paid three times a week (Frequent Payment Group), while others received $2 per assessment paid biweekly (Large Payment Group), and some continued to receive $1 per assessment paid biweekly (Standard Payment Group) for the next 4 weeks. We found that the experimental payment variations did not significantly change compliance with the assessments. These preliminary findings serve as a benchmark for further research.

Research examining the role of place in Black adolescents' health behaviors typically examines neighborhoods, with little attention paid to micro geographies such as activity spaces. Understanding experiences in activity spaces may be especially important for Black adolescents living in neighborhoods traditionally characterized as disadvantaged. The SPIN project recruited 75 Black adolescents living in a single neighborhood to complete ecological momentary assessments (EMA) about the activity spaces they encountered over a month. Perceptions of violence and social support in activity spaces in a day are related to marijuana use during the day, relationships partially explained by negative momentary emotions.

Underrepresentation of historically marginalized populations in clinical trials continues to threaten the validity of health intervention research. Evidence supports the merits of intercept and other proactive forms of recruitment for achieving more equitable representation. However, researchers also report lower retention and adherence to protocols among these populations, particularly in longitudinal studies. Few studies have compared recruitment methods for longitudinal randomized trials testing health interventions, with even fewer having done so for trials involving ecological momentary assessment (EMA). As intervention research integrates EMA and other data collection approaches requiring substantial participant effort, it is critical to better understand the effectiveness and implications of strategies to improve the representativeness of health research. This secondary data analysis compared outcomes of proactive and reactive recruitment strategies (mobile lab intercepts and internet/flyer advertising, respectively) in study inclusion, task completion, and retention within a 14-day randomized controlled trial that used EMA to evaluate cigarette package health messages. Proactive recruitment resulted in higher proportions of participants with low income and education, limited health literacy, and of diverse racial/ethnic makeup. However, this recruitment method also resulted in lower task completion, especially in the second week of the trial period, and lower retention, although group differences were not explained by participant sociodemographic characteristics targeted by inclusion efforts. We conclude that proactive recruitment via intercepts is an effective strategy for health intervention research that aims to include stakeholders from historically marginalized groups but that researchers and funders must recognize these methods require additional resources, considerations, and capacity to address non-trivial challenges to successful participation.

PURPOSE/OBJECTIVES: We aimed to assess the feasibility and acceptability of mobile ecological momentary assessment (mEMA) for youth with craniopharyngioma and evaluate daily associations among family functioning, affect, and sleep difficulties. DESIGN/RESEARCH APPROACH: Youth completed two mEMA diaries per day for one week. SAMPLE/PARTICIPANTS: Thirty-nine youth who underwent surgery and proton radiotherapy (when indicated) for craniopharyngioma. METHODS/METHODOLOGICAL APPROACH: Descriptive statistics and multi-level modeling were used to examine feasibility and acceptability of mEMA and daily associations among family functioning, affect, and sleep. FINDINGS: Youth reported satisfaction and minimal burden from completing daily mEMA diaries. Poorer family functioning was not related to lower sleep efficiency. CONCLUSIONS/INTERPRETATION: mEMA is an acceptable and feasible method for evaluating sleep and related variables in children and adolescents with craniopharyngioma. IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS OR POLICY: Results highlight the utility of gathering mEMA data in youth at elevated risk for sleep difficulties as a function of their illness/treatment.

BACKGROUND: Understanding affect as a determinant of physical activity has gained increased attention in health behavior research. Fluctuations in affect intensity from moment-to-moment (i.e., affective variability) may interfere with cognitive and regulatory processes, making it difficult to engage in goal-directed behaviors such as physical activity. Preliminary evidence indicates that those with greater trait-level affective variability engage in lower levels of habitual physical activity. However, the extent to which daily fluctuations in affect variability are associated with same-day physical activity levels is unknown. This study used ecological momentary assessment (EMA) to investigate day-level associations between affective variability (i.e., within-subject variance) and physical activity. METHODS: Young adults (N = 231, M = 23.58 ± 3.02 years) provided three months of smartphone-based EMA and smartwatch-based activity data. Every two weeks, participants completed a 4-day EMA measurement burst (M = 5.17 ± 1.28 bursts per participant). Bursts consisted of hourly randomly-prompted EMA surveys assessing momentary positive-activated (happy, energetic), positive-deactivated (relaxed), negative-activated (tense, stressed), and negative-deactivated (sad, fatigued) affect. Participants continuously wore a smartwatch to measure physical activity across the three months. Mixed-effects location scale modeling examined the day-level associations of affective variability (i.e., positive-activated, positive-deactivated, negative-activated, and negative-deactivated) and physical activity, controlling for covariates such as mean levels of affect, between-subject effects of physical activity, time of day, day of week, day in study, and smartwatch wear time. RESULTS: There were 41,546 completed EMA surveys (M = 182.22 ± 69.82 per participant) included in the analyses. Above and beyond mean levels of affect, greater day-level variability in positive-activated affect was associated with greater physical activity on that same day compared to other days (τ = 0.01, p < .001), whereas greater day-level variability in negative-deactivated affect was associated with less physical activity on that same day compared to other days (τ = -0.01, p < .001). Day-level variability in positive-deactivated affect or negative-activated affect were not associated with day-level physical activity (ps > .05) CONCLUSIONS: Individuals were less active on days with greater variability in feeling sad and fatigued but more active on days with greater variability in feeling happy and energetic. Understanding the dynamic relationships of affective variability with day-level physical activity can strengthen physical activity interventions by considering how these processes differ within individuals and unfold within the context of daily life. Future research should examine causal pathways between affective variability and physical activity across the day.

OBJECTIVE: This study investigated the association between morning pleasant anticipation (i.e., how pleasant will the day be?) and daily positive incidental affect (PIA, e.g., feeling enjoyable, energetic) on daily steps as measured by ecological momentary assessment (EMA) and accelerometry. METHODS: A total of 152 adults in Taiwan (female = 67.1 %, age range = 18-59, M = 24.97) completed smartphone-based surveys upon waking and at three quasi-random times during the day for seven days during the COVID-19 outbreak (February-July 2022). They also wore accelerometers for the same seven days to measure physical activity (daily steps). The morning survey asked participants to self-report pleasant anticipation throughout the day, and the three quasi-random time surveys assessed current PIA. Multilevel modeling was used to examine day-level associations between morning pleasant anticipation, PIA, and daily steps. A list of key covariates (i.e., age, sex, educational attainment, marital status, living arrangement, chronic disease, body mass index [BMI], smoking, drinking, wellbeing, daily sleep quality, daily sleep hours, and accelerometer wear time) were included in the models to adjust for the covariates' potential effects on the study outcomes. RESULTS: The study sample consisted of 989 morning observations and 2714 quasi-random time observations (EMA response rate = 87.01 %). Findings suggest that higher-than-usual levels of pleasant anticipation in the morning were significantly associated with more same-day daily steps (b = 0.03, SD = 0.01, p = .03) after adjusting for covariates. In addition, daily PIA was a significant moderator between morning pleasant anticipation and daily steps (b = 0.02, SD = 0.01, p < .01), such that higher levels of daily PIA were associated with greater increases in daily steps in response to higher levels of morning pleasant anticipation. CONCLUSION: On days when participants had higher levels of pleasant anticipation in the morning, they took more steps per day. In addition, the association between morning pleasant anticipation and steps per day was stronger on days when participants had higher levels of PIA. These findings have practical implications for future EMA studies investigating the "anticipatory" affective processes on movement behaviors with the goal of promoting physical activity in daily life.

OBJECTIVE: To critically synthesize and describe the use and methods of ecological momentary assessment (EMA) in cancer research. DATA SOURCES: A systematic review was conducted and has been reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) Guideline. Electronic databases (APA PsycINFO, CINAHL, Cochrane Central Register of Controlled Trials, MEDLINE, Scopus, and Web of Science Core Collection) were searched using a variety of keywords and subject headings by an expert systematic review librarian. All publications were double screened by two reviewers using predetermined exclusion and inclusion criteria throughout the full review process. The review used Covidence Systematic Review Software. Methodological quality assessment and data extraction were performed. A narrative synthesis was conducted to examine the aim for EMA, the characteristics of the study samples, the EMA sampling procedures, EMA completion rates, outcome measures, and any implications of findings for survivorship care. CONCLUSION: A total of 42 EMA studies in cancer were included. Most studies used an electronic mobile device to capture EMA data apart from several that used paper diaries. Existing studies were found to have significant heterogeneity in methods and widely varying approaches to design and self-report measurements. While EMA in cancer research holds significant promise to advance cancer care research into the future by increasing ecological validity and reducing retrospective bias and can capture the unique idiographic within-person change over time, in real-time, further research is needed to develop standardized EMA self-report questionnaires. IMPLICATIONS FOR NURSING PRACTICE: This is the first comprehensive systematic review to describe the use and methods of EMA in cancer research. There is significant heterogeneity in methods and widely varying approaches to design and self-report measurements in EMA cancer research. People affected by cancer found taking part in EMA studies reported benefit from the experience. However, researchers must engage with cancer survivors in the development and co-design of future EMA questionnaires to ensure relevant and acceptability of EMA data collection protocols.
