Latina Adolescent Sleep and Mood: An Ecological Momentary Assessment Pilot Study

Stress, positive affect, and sleep in older African American adults: a test of the stress buffering hypothesis

BACKGROUND

Although sleep disparities contribute to racial health disparities, little is known about factors affecting sleep among African Americans. One such factor may be positive affect, which could impact sleep directly (direct effect hypothesis) or indirectly by buffering the effects of stress (stress buffering hypothesis).

PURPOSE

We tested the direct effect and stress buffering effects of positive affect on sleep at three levels (day, week, trait) in a sample of 210 older African American adults, ranging in age from 50 to 89 years old.

METHOD

Daily positive affect, perceived stress, sleep quality, and sleep duration were collected for five consecutive days. Multilevel modeling was used to test the direct and stress buffering hypotheses both within-person (day level) and between-persons (week level). Trait positive affect, past five-year stress severity, and global sleep quality were assessed cross-sectionally. Regression was used to test the direct and stress buffering hypotheses at the trait level.

RESULTS

In line with the direct effect hypothesis, higher week-level positive affect predicted better sleep quality and sleep duration. Day-level positive affect was not significantly associated with daily sleep quality or daily sleep duration. Higher trait positive affect predicted better global sleep quality. However, neither day-level perceived stress nor past five-year stress severity significantly interacted with positive affect measures for any sleep outcome; no interaction effect was observed on week-level sleep duration. Positive affect and perceived stress interacted at the week level to predict sleep quality, but not in the hypothesized direction.

CONCLUSIONS

We found support for the direct effect hypothesis at the week- and trait-levels, but not at the day level. In contrast, we found no support for the stress buffering hypothesis.

Monitoring Daily Sleep, Mood, and Affect Using Digital Technologies and Wearables: A Systematic Review

Background: Sleep and affective states are closely intertwined. Nevertheless, previous methods to evaluate sleep-affect associations have been limited by poor ecological validity, with a few studies examining temporal or dynamic interactions in naturalistic settings. Objectives: First, to update and integrate evidence from studies investigating the reciprocal relationship between daily sleep and affective phenomena (mood, affect, and emotions) through ambulatory and prospective monitoring. Second, to evaluate differential patterns based on age, affective disorder diagnosis (bipolar, depression, and anxiety), and shift work patterns on day-to-day sleep-emotion dyads. Third, to summarise the use of wearables, actigraphy, and digital tools in assessing longitudinal sleep-affect associations. Method: A comprehensive PRISMA-compliant systematic review was conducted through the EMBASE, Ovid MEDLINE(R), PsycINFO, and Scopus databases. Results: Of the 3024 records screened, 121 studies were included. Bidirectionality of sleep-affect associations was found (in general) across affective disorders (bipolar, depression, and anxiety), shift workers, and healthy participants representing a range of age groups. However, findings were influenced by the sleep indices and affective dimensions operationalised, sampling resolution, time of day effects, and diagnostic status. Conclusions: Sleep disturbances, especially poorer sleep quality and truncated sleep duration, were consistently found to influence positive and negative affective experiences. Sleep was more often a stronger predictor of subsequent daytime affect than vice versa. The strength and magnitude of sleep-affect associations were more robust for subjective (self-reported) sleep parameters compared to objective (actigraphic) sleep parameters.

Anxiety-related constructs and smoking outcome expectancies among Latinx smokers

Hispanic/Latinx (hereafter Latinx) smokers in the United States (US) experience unique smoking cessation-related challenges. Smoking outcome expectancies (i.e., positive and negative beliefs about the consequences of smoking behavior) have been linked to the maintenance of smoking and comorbidity with negative emotional states such as anxiety among Latinx smokers. However, past work has not characterized rates of probable anxiety disorder and elevated levels of anxiety sensitivity among English-speaking daily Latinx smokers from the United States or concurrently evaluated the explanatory relevance of anxiety symptoms and anxiety sensitivity for negative and positive smoking outcome expectancies. The present investigation sought to (a) determine the base rate of probable anxiety disorder and elevated anxiety sensitivity and (b) explore the unique roles of anxiety symptoms and anxiety sensitivity in relation to negative and positive smoking outcome expectancies. Participants included 338 English-speaking Latinx adult daily cigarette smokers from the United States (Mage = 35.53 years; SD = 8.65; age range 18-61; 37.3% female). Findings revealed high rates of probable anxiety disorder (50.9%) and elevated anxiety sensitivity (73.4%) among English-speaking Latinx smokers from the United States. Anxiety sensitivity, but not anxiety symptoms or disorders, was significantly related to negative consequences, negative reinforcement, positive reinforcement, and appetite/weight control smoking outcome expectancies. Overall, anxiety experiences were common among Latinx smokers, and anxiety sensitivity was a relatively more consistent and robust predictor of negative and positive outcome expectancies relative to anxiety symptoms and probable anxiety disorder.

Sleep quality and in-person versus online social interaction during the early COVID-19 pandemic lockdown: Impact on affect and interpersonal needs among young adults

We examined relationships among sleep quality and forms of social interaction (in-person vs. online) as predictors of change in affect and interpersonal needs (perceived burdensomeness, thwarted belongingness) - correlates of suicidal thoughts and behaviors - during the early COVID-19 pandemic lockdown. New York City undergraduates (N = 58) from four public colleges completed a baseline survey and daily diaries up to 30 days in April-June 2020. Adjusting for relevant covariates, better sleep quality and in-person communication predicted greater positive affect and lower negative affect over time, but online social interaction only predicted greater positive affect and did not predict negative affect. Better sleep quality predicted lower perceived burdensomeness but not thwarted belongingness. Both in-person and online social interaction - but not total hours on social media - predicted lower thwarted belonging and perceived burdensomeness. Greater hours spent on social media each day lessened the relationship between in-person interaction and positive affect and lessened the buffering effect of in-person interaction on perceived burdensomeness. Improving sleep quality and increasing in-person interaction may ameliorate psychological variables that increase risk for suicidal thoughts and behaviors. However, when in-person interaction is limited, such as during the COVID-19 pandemic, online social interaction might be encouraged - depending on the nature of the interactions - to increase positive affect and buffer against suicide-related factors.

Eating to cope: Advancing our understanding of the effects of exposure to racial discrimination on maladaptive eating behaviors

OBJECTIVE

Racial discrimination is a stressor for young Black women that leads to poor health outcomes, including maladaptive eating. This study presents findings on racial discrimination and maladaptive eating behaviors (overeating, LOC eating) using ecological momentary assessment (EMA).

METHODS

Black emerging adult women (N = 27) with overweight or obesity participated in a 14-day EMA study examining exposure to racial discrimination, eating behaviors, and racial identity. Frequencies and chi-square tests were used to characterize the type of racial discrimination experienced and frequency of overeating. Mixed effect ordinal logistic regression models were used to assess the relation between racial discrimination and maladaptive eating. Moderation analysis was conducted by creating interaction terms for discrimination and racial identity variables.

RESULTS

81.5% of participants reported experiencing racial discrimination. Young Black women reporting exposure to racial discrimination were more likely to endorse higher levels of both overeating and LOC eating compared to times when discrimination was not experienced (p < .0001). Racial identity moderated the link between racial discrimination and maladaptive eating (overeating, LOC) such that reporting greater levels of private regard buffered the deleterious effect of racial discrimination. Higher levels of public regard exacerbated the association between racial discrimination and both overeating, and LOC. Higher centrality worsened the relation between racial discrimination and LOC.

CONCLUSION

Young Black women might use maladaptive eating to cope with exposure to racial discrimination, which underscores the importance of examining the link between racism and disordered eating, particularly among Black women submerged in a society that continuously exposes them to racial discrimination.

PUBLIC SIGNIFICANCE

Emerging adult Black women are exposed to racial discrimination daily. In theory, exposure to racial discrimination could contribute to overeating and loss of control eating in this population. Using ecological momentary assessment, to capture experiences and eating behaviors in the moment they occur, this project quantified the magnitude of racial discrimination and how it was associated with maladaptive eating behaviors. Further, it examined ways in which racial identity was linked to this association.

Worry among Latinx college students: relations to anxious arousal, social anxiety, general depression, and insomnia

OBJECTIVE

Latinx young adults in college (ages 18-25 years) are at a heightened risk for health disparities and there is a need to understand individual-based characteristics that are related to such health inequalities including anxiety, depression, and sleep disturbances. The cross-sectional current study investigated the role of worry in relation to anxious arousal, social anxiety, general depression, and insomnia among Latinx college students. Participants/Method: Participants included 401 (Mage = 21 years; SD =2.01; 83% female) Latinx students at a large, southwestern university. Results: Results indicated that greater levels of worry were related to increased levels of anxious arousal, social anxiety, general depression, and insomnia. These findings were evident above and beyond variance accounted for by age, sex, and subjective social status. Conclusions: The current investigation suggests that elevated levels of worry among Latinx young adults may be associated with greater levels of anxiety, depression, and insomnia.

Associations between daily affect and sleep vary by sleep assessment type: What can ambulatory EEG add to the picture?

OBJECTIVE/BACKGROUND

Disrupted sleep can be a cause and a consequence of affective experiences. However, daily longitudinal studies show sleep assessed via sleep diaries is more consistently associated with positive and negative affect than sleep assessed via actigraphy. The objective of the study was to test whether sleep parameters derived from ambulatory electroencephalography (EEG) in a naturalistic setting were associated with day-to-day changes in affect.

PARTICIPANTS/METHOD

Eighty adults (mean age = 32.65 years, 63% female) completed 7 days of affect and sleep assessments. We examined bidirectional associations between morning positive affect and negative affect with sleep assessed via diary, actigraphy, and ambulatory EEG.

RESULTS

Mornings with lower positive affect than average were associated with higher diary- and actigraphy-determined sleep efficiency that night. Mornings with higher negative affect than average were associated with longer actigraphy-determined total sleep time that night. Nights with longer diary-determined total sleep time, greater sleep efficiency, and shorter sleep onset latency than average were associated with higher next-morning positive affect, and nights with lower diary-determined wake-after-sleep-onset were associated with lower next-morning negative affect. EEG-determined sleep and affect results were generally null in both directions: only higher morning negative affect was associated with longer rapid eye movement (REM) sleep that night.

CONCLUSIONS

Self-reported sleep and affect may occur in a bidirectional fashion for some sleep parameters. EEG-determined sleep and affect associations were inconsistent but may still be important to assess in future studies to holistically capture sleep. Single-channel EEG represents a novel, ecologically valid tool that may provide information beyond diaries and actigraphy.

Interstitial glucose and subsequent affective and physical feeling states: A pilot study combining continuous glucose monitoring and ecological momentary assessment in adolescents

OBJECTIVE

Circulating glucose may relate to affective and physical feeling states reflective of emotional disorder symptoms. No prior studies have investigated within-day associations between glucose and subsequent affective and physical feeling states (positive affect, negative affect, and fatigue) as they occur naturally among healthy adolescents; this pilot study assessed these associations by combining data collected from ecological momentary assessment (EMA) and continuous glucose monitors (CGM).

METHODS

Participants (N = 15, mean age = 13.1[±1.0] years, 66.7% female, 40.0% Hispanic, 66.7% healthy weight) wore a CGM for 7-14 days. Simultaneously, participants reported on their current positive affect, negative affect, and fatigue randomly during specified windows up to 7 times daily via EMA. CGM-measured mean interstitial glucose was calculated during the time windows (mean minutes = 122.5[±47.3]) leading up to each EMA prompt. Multilevel models assessed within-subject (WS) associations between mean interstitial glucose since the previous EMA prompt and EMA-reported affective and physical feeling states at the current prompt.

RESULTS

Participants provided 532 interstitial glucose-matched EMA reports of affective and physical feeling states. During intervals when interstitial glucose was higher than one's usual, higher positive affect (WS β = 0.01, p < .0001, f² = 0.02) and lower fatigue (WS β = -0.01, p < .0001, f² = 0.09) were subsequently reported. Interstitial glucose was unrelated to negative affect (WS β = -0.002, p = .10, f² = 0.01). Associations were weakened, but remained significant following further adjustment for time of day.

CONCLUSIONS

Though effect sizes were small, within-person variations in interstitial glucose may relate to subsequent affective and physical feeling states among healthy youth. Investigations using similar methodologies in larger, more diverse samples are warranted.

Pain-Related Anxiety Among Latinx College Students: Relations to Body Vigilance, Worry, Anxious Arousal, and General Depression

Latinx young adults in college (ages 18-25 years) are at an elevated risk for somatic and mental health disparities. Although the experience of pain is among the most common health complaints among Latinx young adults, there is no scientific information about how cognitive-based responses to pain relate to somatic vigilance and mental health among this group. The current study therefore investigated the explanatory role of pain-related anxiety (worry about negative consequences of pain) in terms of body vigilance, worry, anxious arousal, and general depression among Latinx young adults. Participants were Latinx college students (M_age = 21 years; SD = 2.02; 83% female) at a large, southwestern university. Results indicated that greater levels of pain-related anxiety were associated with significantly greater bodily vigilance, worry, anxious arousal, and general depression after adjusting for age, gender, physical functioning, subjective social status, and pain intensity. The current investigation suggests that Latinx young adults who experience elevated levels of pain-related anxiety may be at greater risk for somatic hypervigilance and negative affect symptoms. Therefore, reducing pain-related anxiety among Latinx young adults may be an important therapeutic strategy in efforts to reduce somatic and mental health disparities among this group.

Nursing Disruption for Achieving Sustainable Development Goals by 2030

Sixteen million nurses, the largest global health care workforce, contribute to achievement of 17 United Nations Sustainable Development Goals through strategic and disruptive research, education, practice, and policy. Responsible for advancing the well-being of individuals, families, communities, and society, nurses are positioned to influence and impact health across the life span. They do this from promoting prenatal health and early childhood success to encouraging healthy aging and end-of-life transitions. They utilize both predictive analytics that prevent rehospitalization and evidence-based practices, such as rocking and kangaroo care, that encourage survival and thriving of preterm newborns. Nurses have a scope of practice that necessitates their presence essentially everywhere. Direct nursing care is delivered in homes, schools, correctional settings, districts, hospitals, helicopters, combat zones, refugee camps, and postnatural disaster or homeless shelters. Nurses advancing system-level health are positioned in health care administration, higher education, international nongovernmental organizations, and governmental offices. Nurse educators and researchers shape tomorrow's practitioners and practice. In general, nurses innovate and generate solutions to improve global health. Shared in this article are strategies for nurses to employ to disrupt the status quo and aggressively contribute to achieving the 2030 Sustainable Development Goals.

PlenadrEMA: effect of dual-release versus conventional hydrocortisone on fatigue, measured by ecological momentary assessments: a study protocol for an open-label switch pilot study

INTRODUCTION

Patients with adrenal insufficiency have impaired health-related quality of life (QoL). The dual-release hydrocortisone preparation, Plenadren, has been developed to mimic the physiological cortisol release more closely than conventional hydrocortisone treatment. Plenadren has been shown to improve QoL, in particular fatigue, in patients with primary adrenal insufficiency. However, the effect has not been investigated in patients with secondary adrenal insufficiency; furthermore, no study has taken the diurnal variation of fatigue into account. To assess diurnal variations, it is necessary to use repeated daily measurements, such as ecological momentary assessments (EMAs). This study aims to evaluate EMAs of fatigue as outcome in future large-scale randomised clinical trials.

METHODS AND ANALYSIS

The PlenadrEMA trial is an investigator-initiated open-label switch pilot trial of the effect of Plenadren versus conventional hydrocortisone on fatigue in patients with secondary adrenal insufficiency. The trial will include 30 participants. After 5 weeks on their usual hydrocortisone treatment, patients will be shifted to Plenadren for 16 weeks. Fatigue will be assessed using momentary versions of the Multidimensional Fatigue Inventory (MFI-20). Items will be administered to participants via a smartphone application four times daily during 20 days. Assessments will be performed before treatment shift and repeated after 12.5 weeks on Plenadren. The study will identify the best suited outcome for future randomised clinical trials, and in addition, estimate the variability and difference in fatigue between the two treatments to perform power calculations.

ETHICS AND DISSEMINATION

The trial will be conducted in accordance with the Declaration of Helsinki and has been approved by the Regional Scientific Ethical Committee in Copenhagen (ID: H-1-2014-073). All patients will receive written and verbal information about the trial and will give informed consent before enrolment. Findings will be published in peer-reviewed journals and presented at international conferences.

Using Mobile-Technology-Based Ecological Momentary Assessment (EMA) Methods With Youth: A Systematic Review and Recommendations

Ecological momentary assessment (EMA) methods are increasingly used in social and health sciences, but the feasibility and best practices for using EMA with youth are not yet clear. We conducted a systematic review of studies that used self-report EMA methods with youth; the goal was to identify common approaches and challenges to implementation and develop recommendations for future research. We examined 54 peer-reviewed papers that reported on 24 unique studies. Papers were evaluated using a standardized, three-dimensional coding scheme focused on the following: (1) sample characteristics; (2) EMA data collection methods (sampling duration, frequency, hardware/software); (3) study implementation methods (technical/logistical challenges, training participants, compliance). Overall, the research suggests EMA can be successfully implemented with youth (age ∼ ≥7) from diverse backgrounds, but protocol adaptations may be necessary for younger children. Study design and implementation challenges and recommendations for research on youth are provided.

Daily nicotine patch wear time predicts smoking abstinence in socioeconomically disadvantaged adults: An analysis of ecological momentary assessment data

INTRODUCTION

Individuals who use the nicotine patch are more likely to quit smoking than those who receive placebo or no medication. However, studies have not yet examined the association between actual daily nicotine patch wear time during the early phase of a smoking cessation attempt and later smoking abstinence. The purpose of this study was to address this gap in the literature.

METHODS

Participants who enrolled in a safety-net hospital smoking cessation program were followed for 13 weeks (i.e., 1 week pre-quit through 12 weeks post-quit). Participants completed in-person assessments and daily ecological momentary assessments on study provided smartphones. Multivariate logistic regressions were used to determine if daily patch wear time during the first week post-quit predicted 7-day biochemically verified point prevalence smoking abstinence 4 and 12 weeks following the scheduled quit date. Demographic characteristics and smoking behaviors were adjusted as covariates.

RESULTS

Participants (N=74) were primarily non-White (78.7%) and most (86%) had an annual household income of <$20,000. Greater average hours of daily nicotine patch wear time during the first week post-quit was associated with a greater likelihood of abstinence at the 4 and 12 week post-quit visits (aOR=2.22, 95% CI:1.17-4.23; aOR=2.24, 95% CI:1.00-5.03). Furthermore, more days of wearing the patch for ≥19h was associated with a greater likelihood of abstinence at the 4 and 12 week post-quit visits (aOR=1.81, 95% CI:1.01-3.22; aOR=2.18, 95% CI:1.03-4.63).

CONCLUSIONS

Greater adherence to the nicotine patch early in a quit attempt may increase the likelihood of smoking cessation among socioeconomically disadvantaged adults.

Developing an Internet- and Mobile-Based System to Measure Cigarette Use Among Pacific Islanders: An Ecological Momentary Assessment Study

BACKGROUND

Recent prevalence data indicates that Pacific Islanders living in the United States have disproportionately high smoking rates when compared to the general populace. However, little is known about the factors contributing to tobacco use in this at-risk population. Moreover, few studies have attempted to determine these factors utilizing technology-based assessment techniques.

OBJECTIVE

The objective was to develop a customized Internet-based Ecological Momentary Assessment (EMA) system capable of measuring cigarette use among Pacific Islanders in Southern California. This system integrated the ubiquity of text messaging, the ease of use associated with mobile phone apps, the enhanced functionality offered by Internet-based Cell phone-optimized Assessment Techniques (ICAT), and the high survey completion rates exhibited by EMA studies that used electronic diaries. These features were tested in a feasibility study designed to assess whether Pacific Islanders would respond to this method of measurement and whether the data gathered would lead to novel insights regarding the intrapersonal, social, and ecological factors associated with cigarette use.

METHODS

20 young adult smokers in Southern California who self-identified as Pacific Islanders were recruited by 5 community-based organizations to take part in a 7-day EMA study. Participants selected six consecutive two-hour time blocks per day during which they would be willing to receive a text message linking them to an online survey formatted for Web-enabled mobile phones. Both automated reminders and community coaches were used to facilitate survey completion.

RESULTS

720 surveys were completed from 840 survey time blocks, representing a completion rate of 86%. After adjusting for gender, age, and nicotine dependence, feeling happy (P=<.001) or wanting a cigarette while drinking alcohol (P=<.001) were positively associated with cigarette use. Being at home (P=.02) or being around people who are not smoking (P=.01) were negatively associated with cigarette use.

CONCLUSIONS

The results of the feasibility study indicate that customized systems can be used to conduct technology-based assessments of tobacco use among Pacific Islanders. Such systems can foster high levels of survey completion and may lead to novel insights for future research and interventions.
