Daily social comparisons among women in midlife with elevated risk for cardiovascular disease: A within-person test of the identification/contrast model.

Women age 40-60 are disproportionately affected by health problems that increase their risk for cardiovascular disease (CVD; e.g. hypertension). Social comparisons (i.e. self-evaluations relative to others) are known to influence health in this and other groups, but their nature and consequences in daily life are poorly understood. We conducted an ecological momentary assessment study over 10days (5x/day) with 75 women ages 40-60 who had ≥1 CVD risk conditions (MAge = 51.6years, MBMI = 34.0kg/m2). Using a mix of frequentist and Bayesian analytic approaches, we examined characteristics of women's naturally occurring comparisons and tested predictions from the Identification/Contrast Model within-person (e.g. identifying with an upward target results in positive affect, whereas contrasting results in negative affect). Comparisons occurred at 21% of moments, with considerable within-person variability in response. In line with predictions from the Identification/Contrast Model, women were more likely to experience positive affect after upward identification or downward contrast and more likely to experience negative affect after upward contrast or downward identification, though observed nuances warrant additional consideration. Overall, findings support the Identification/Contrast Model to describe women's comparison experiences as they occur in daily life. Future work should determine pathways between the immediate consequences of comparisons and longer-term health outcomes.

Within- and between-person associations of time-varying determinants with snacking in older adults: an EMA study.

Promoting healthy snacking is important in addressing malnutrition, overweight and obesity among an ageing population. However, little is known about the factors underlying snacking behaviour in older adults. The present study aimed to explore within- and between-person associations between determinants (i.e. intention, visibility of snacks, social modelling and emotions) and snacking behaviours (i.e. decision to snack, health factor of the snack and portion size) in older adults (60+). Conducting a two-part intensive longitudinal design, data was analysed from 48 healthy older adults consisting of (1) an event-based self-report ecological momentary assessment (EMA) diary every time they had a snack and (2) a time-based EMA questionnaire on their phone 5 times per day. Analysis through generalised linear mixed models indicated that higher intention to snack healthily leads to healthier snacking while higher levels of social modelling and cheerfulness promote unhealthier choices within individuals. At the between-person level, similar results were found for intention and social modelling. Visibility of a snack increased portion size at both a within- and between-person level, while the intention to eat a healthy snack only increased portion size at the between-person level. No associations were found between the decision to snack and all determinants. This is the first study to investigate both within- and between-person associations between time-varying determinants and snacking in older adults. Such information holds the potential for incorporation into just-in-time adaptive interventions, allowing for personalised tailoring, more effective promotion of healthier snacking behaviours and thus, pursuing the challenge of healthy ageing.

A closer look into the affect dynamics of adolescents with depression and the interactions with their parents: An ecological momentary assessment study.

Adolescents with depression tend to perceive behavior of parents as less positive than adolescents without depression, but conclusions are based on retrospective reports assessed once or over long time intervals, with the risk of memory biases affecting the recall. The current study used ecological momentary assessments to examine the link between adolescent affect and the amount of warmth and criticism expressed by both mothers and fathers in families with adolescents with depression versus adolescents without psychopathology in daily life. It also explored the possible bias by assessing parenting on the momentary, daily (EMA), and retrospective level. The sample consisted of 34 adolescents with depression and 58 parents and 80 healthy controls and 151 parents (adolescents: Mage = 15.8, SD = 1.41; 67.5% girls, parents: Mage = 49.3, SD = 5.73; 54.1% mothers). Participants completed retrospective questionnaires and four surveys a day for 14 consecutive days. Preregistered multilevel models showed that momentary parenting reports of adolescents with depression and healthy controls did not differ. The associations between perceived parenting of both mothers and fathers and adolescent affect did also not differ between the two groups. These results illustrate that adolescents generally benefit from supportive parenting, but substantial differences between individuals were found. In contrast to the momentary data, both adolescents with depression and their parents did report more negative parenting on retrospective questionnaires than healthy controls and their parents indicating that adolescents with depression may have a negativity bias in their retrospective recall. These findings are highly relevant for clinical practice and underscore the need for careful assessments on different time scales and including all family members.

Quantifying cigarette and e-cigarette marketing exposure among Chinese adolescents using ecological momentary assessment.

Addressing cigarette and e-cigarette use in China is key to reducing the global tobacco epidemic. Marketing exposure is one causal factor for adolescent smoking and e-cigarette use. Currently, China restricts cigarette and e-cigarette ads in public places and online; however, there may not be full policy compliance. We collected real-time data in the natural environment to estimate how much and where Chinese adolescents - a group susceptible to smoking and e-cigarette use - are exposed to cigarette and e-cigarette marketing to inform policy responses. In June 2022, we conducted a seven-day ecological momentary assessment (EMA) study with 15-16-year-olds (n=96) across eight Chinese cities. Participants completed up to 42 EMA surveys (6 per day), sent at random intervals outside of school hours. In each survey, participants reported whether they saw (1) displays and (2) ads in the past hour (none, cigarette, e-cigarette, both) in the past hour. We also captured the source of cigarette/e-cigarette ad exposure. Most participants were exposed to cigarette and/or e-cigarette displays (89.6%) or ads (79.2%) over the seven days. On average, participants reported past-hour exposure to displays 12.7 times and past-hour exposure to ads 10.8 times over the week. The most common sources of cigarette ads were public places (e.g., kiosks, supermarkets); the most common sources of e-cigarette ad exposure were social media/internet or e-cigarette stores. Findings highlight the need to enhance enforcement of restrictions on cigarette and e-cigarette ads in public places and online in China and extend restrictions to ban displays. Marketing exposure is a causal factor in youth smoking and e-cigarette use. We used ecological momentary assessments to estimate cigarette and e-cigarette display and ad exposure among Chinese adolescents. On average, participants reported past-hour exposure to cigarette and/or e-cigarette displays 13 times and past-hour exposure to cigarette and/or e-cigarette ads 11 times over one week. Most saw ads in public places and online. Results suggest strengthening implementation of China's ban on cigarette and e-cigarette ads in public places and online and banning product displays. These are policy responses that can contribute to reducing adolescent cigarette and e-cigarette uptake in China.

Within-person fluctuations of fatigue in patients with a clinical diagnosis of systemic sclerosis and its relationship with mood, pain, sleep and physical activity

Objectives: To explore the within-person fluctuations of fatigue in systemic sclerosis and its association with negative affect, positive affect, pain, perceived exertion of physical activity and quality of sleep. Methods: We performed an ecological momentary assessment study in adult patients with a clinical diagnosis of systemic sclerosis. During 14 days, patients completed daily assessments of fatigue severity, negative affect, positive affect, pain, quality of sleep and perceived exertion of physical activity at four fixed time points. The day-to-day fluctuations in fatigue were quantified by the intra-individual variance and probability of acute change, capturing the magnitude and frequency of clinical relevant within-person day-to-day fluctuations, respectively. Using multilevel models, the within-person association between fatigue and the daily assessments were analysed. Results: Fifty-seven patients with systemic sclerosis participated. The mean (standard deviation) intra-individual variance was 1.08 (0.42) and the probability of acute change was mean (standard deviation) 0.40 (0.14), ranging from 0.08 to 0.77. For fatigue, a within-person variation of 51% was observed. Multilevel analyses showed that higher average levels and daily increases in negative affect, pain and perceived exertion of physical activity were associated with more fatigue, while the opposite was observed for positive affect and quality of sleep. Positive affect demonstrated the strongest association with fatigue fluctuations. Conclusion: This is the first quantitative study showing that fatigue in systemic sclerosis is characterized by a dynamic course and that approximately half of the day-to-day fluctuations within persons are clinically meaningful. Furthermore, our results indicate that integrating activities with positive impact on mood into fatigue treatment strategies might reduce the frequency of fatigue fluctuations.

Momentary Emotion Regulation Strategies and Pain Experience Among Adults With Chronic Pain: An Ecological Momentary Assessment Study.

The intention of this study was to characterize the real-time momentary relationship between emotion regulation strategies and the pain experience (ie intensity, interference, and negative affect) among adults with chronic pain. Chronic pain is a significant public health concern. Psychological treatments are effective for treating chronic pain, but long-term follow-up studies are limited, and treatment effect sizes are small. Identifying modifiable treatment targets, such as emotion regulation (ER), is critical to improve interventions. ER (ie, cognitive and attentional strategies to modulate or maintain emotional experience) has been linked to psychopathology and pain experience in adults. Yet, the existing work is limited and has largely focused on the relationship between emotional experience, not ER, and pain. The current study utilized ecological momentary assessment 53 adults with chronic pain. Participants completed ecological momentary assessments of pain experience and ER strategies 5 times a day for 7 days. Associations by specific strategy type were also examined, highlighting the importance of worry, experiential avoidance, rumination, and expressive suppression in pain experience. Results of the current study provide evidence for the association between within-person maladaptive ER strategies and pain intensity ( b = 2.11, SE = 0.37, P < 0.001), pain interference ( b = 1.25, SE = 0.40, P = 0.002), and pain-related negative affect ( b = 2.20, SE = 0.41, P < 0.001). (77.4% females; M age = 27.10 y, SD = 5.16 y). Given that ER is readily targeted in psychological treatments for chronic pain, the results from the current study provide initial evidence to target these ER strategies in treatment.

Retraction of "Event-level risk for negative alcohol consequences in emerging adults: The role of affect, motivation, and context" by Waddell et al. (2024).

Reports the retraction of "Event-level risk for negative alcohol consequences in emerging adults: The role of affect, motivation, and context" by Jack T. Waddell, Scott E. King, Sarah A. Okey and William R. Corbin (Psychology of Addictive Behaviors, 2024[Feb], Vol 38[1], 8-18). This article is being retracted at the request of the publisher, and the editor and all authors of the original article consented. This article was published in error, as it is a first stage Registered Report that has received in-principle acceptance. Given the workflow of a Registered Report, the first journal publication appears after data collection and results have been reported in the second stage Registered Report submission (see workflow at https://www.cos.io/initiatives/registered-reports). This stage one article is being removed from the literature to avoid confusion and will instead be preregistered as a Registered Report Protocol Preregistration (https://osf.io/7euzd/). (The following abstract of the original article appeared in record 2022-80654-001.) Objective: Decades of research has found support for the motivational model of alcohol use, such that positive/negative affect are indirectly associated with drinking behavior through drinking motives. However, research on event-level drinking motives is in its nascent stage, and studies have yet to consider how drinking context plays a role in the motivational pathway to both event- and person-level drinking behavior. Therefore, the present study seeks to test whether drinking context mediates the effect of affect and motivation on drinking outcomes at both the event- and person-level. Method: Data for this Stage 1 Registered Report will come from a recently completed ecological momentary assessment (EMA) study in emerging adults. The study collected data on 131 emerging adults, of whom 107 reported event-level social and solitary drinking during the EMA period. Multilevel structural equation modeling will be used to test whether predrinking affect is associated with predrinking motives, and whether drinking context (social vs. solitary drinking) mediates the effect of drinking motives on drinking outcomes. Models will parse within-/between-person variance, allowing the present study to test whether drinking context serves as a mechanism of risk in the motivational model at the event-level, or solely at the between-person level. Findings will inform personalized interventions and motivational models of drinking behavior. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Social mobile sensing and problematic alcohol consumption: Insights from smartphone metadata

BackgroundAlcohol is often consumed in a social context. We aim to investigate whether social mobile sensing is associated with real-world social interactions and alcohol consumption. Furthermore, we investigate how social restriction policies implemented during the COVID-19 pandemic have influenced these associations. MethodsWe conducted a smartphone-based ecological momentary assessment (EMA) study for 7 days over a 213-day period from 8 August 2020 to 9 March 2021 in Germany, including both no-lockdown and lockdown stages. Participants used a smartphone application which passively collects data on social behavior (e.g., app usage, phone calls, SMS). Moreover, we assessed real-world social interactions and alcohol consumption via daily questionnaires. ResultsWe found that each one-hour increase in social media usage was associated with a 40.2% decrease in the average number of drinks consumed. Mediation analysis suggested that social media usage decreases alcohol intake through decreased real-world social interactions. Notably, we did not find that any significant influence of the lockdown stage on the association between social mobile sensing and alcohol intake. ConclusionsOur study suggests that people who use more social media drink less, likely due to reduced face-to-face social interactions. This highlights the potential of social mobile sensing as an objective measure of social activity and its implications for understanding alcohol consumption behavior.

The Effect of Everyday-Life Social Contact on Pain.

Pain is a biopsychosocial phenomenon, resulting from the interplay between physiological and psychological processes and social factors. Given that humans constantly interact with others, the effect of social factors is particularly relevant. Documenting the significance of the social modulation of pain, an increasing number of studies have investigated the effect of social contact on subjective pain intensity and pain-related physiological changes. While evidence suggests that social contact can alleviate pain, contradictory findings indicate an increase in pain intensity and a deterioration of pain coping strategies. This evidence primarily stems from studies examining the effect of social contact on pain within highly controlled laboratory conditions. Moreover, pain assessments often rely on one-time subjective reports of average pain intensity across a predefined period. Ecological momentary assessments (EMAs) can circumvent these problems, as they can capture diverse aspects of behavior and experiences multiple times a day, in real time, with high resolution, and within naturalistic and ecologically valid settings. These multiple measures allow for the examination of fluctuations of pain symptoms throughout the day in relation to affective, cognitive, behavioral, and social factors. In this opinion paper, we review the current state and future relevance of EMA-based social pain research in daily life. Specifically, we examine whether everyday-life social support reduces or enhances pain. The first part of the paper provides a comprehensive overview of the use of EMA in pain research and summarizes the main findings. The review of the relatively limited number of existing EMA studies shows that the association between pain and social contact in everyday life depends on numerous factors, including pain syndromes, temporal dynamics, the nature of social interactions, and characteristics of the interaction partners. In line with laboratory research, there is evidence that everyday-life social contact can alleviate, but also intensify pain, depending on the type of social support. Everyday-life emotional support seems to reduce pain, while extensive solicitous support was found to have opposite effects. Moreover, positive short-term effects of social support can be overshadowed by other symptoms such as fatigue. Overall, gathering and integrating experiences from a patient's social environment can offer valuable insights. These insights can help interpret dynamics in pain intensity and accompanying symptoms such as depression or fatigue. We conclude that factors determining the reducing versus enhancing effects of social contact on pain need to be investigated more thoroughly. We advocate EMA as the assessment method of the future and highlight open questions that should be addressed in future EMA studies on pain and the potential of ecological momentary interventions for pain treatment.

The Role of Positive and Negative Affect in Illicit Substance Use and Alcohol Use: An Ecological Momentary Assessment Study.

Theories suggest that experiences of negative and positive affect are important precursors to alcohol and illicit substance use. Research utilizing ecological momentary assessments (EMA) has generally supported the relation between momentary experiences of positive affect, but not negative affect, and subsequent substance use. Unfortunately, most of these studies have focused on alcohol use and not other substance use. The goal of this paper was to further explore the relation between momentary affect and use of both alcohol and illicit substances within a population of individuals with a history of substance use. Additionally, this study aimed to understand whether the relations between affect and substance use would vary depending on the timing of EMA assessments of affect prior to substance use. Participants with a history of heavy substance use (N = 59) completed EMA's measuring affect and substance use using random prompts 4 times a day for 14 days. We found that positive affect was significantly related to later engagement in drinking, illicit substance use, and marijuana use. Moreover, timing of the affect was important. When affect was assessed in the last hour prior to substance use, relative to 7 hours prior, the relation between positive affect and illicit substance use was stronger. Negative affect was related to a lower likelihood of subsequent marijuana use, but more so when it was measured a few hours versus several hours before the use. This study further supported the relation between positive affect and both alcohol and illicit substance use.

Are engineers more likely to avoid algorithms after they see them err? A longitudinal study

ABSTRACT Research suggests the superior predictive capabilities of algorithms compared to humans. However, people's reluctance to use algorithms after witnessing their inaccuracies has hindered their widespread adoption. Studies have explored this reluctance, but little is known about how different people use algorithms. We focused on algorithm utilisation by engineers, conducting two longitudinal ecological momentary assessment studies outside the lab to explore differences in how engineers and non-engineers engage with inaccurate algorithms. These studies involved 427 participants, predicting currency exchange rates or maximum weather temperatures over nine days based on the judge-advisor system framework. Our results showed a significant three-way interaction between the effects of advice source, whether participants were engineers or non-engineers, and time. Specifically, the trend of inaccurate algorithm use significantly decreased over time for engineers, highlighting the importance of considering the end-users when implementing algorithms.

Negative affect instability predicts elevated depressive and generalized anxiety disorder symptoms even when negative affect intensity is controlled for: an ecological momentary assessment study.

Mood and anxiety disorders are characterized by abnormal levels of positive affect (PA), negative affect (NA) and changes in how emotions unfold over time. To better prevent and treat those disorders, it is crucial to determine which kind of indices of emotion dynamics best predict elevated depressive and generalized anxiety symptoms. 221 individuals (60 men; mean age = 46 years, SD = 15 years) completed a 7-day ecological momentary assessment study, where their positive and negative affective experience was assessed 5 times a day. For each participant, the intensity, instability, inertia, and differentiation of PA and NA were calculated. The Estonian Emotional State Questionnaire was used to assess depressive and generalized anxiety disorder (GAD) symptoms. We found that NA and PA intensity, and NA instability predicted elevated depressive and GAD symptoms. Models including NA instability alongside PA and NA intensity showed the best fit for both depression and generalized anxiety, as NA instability alongside other variables significantly increased the odds of having elevated depressive and GAD symptoms. Affective inertia, differentiation, and PA instability were not associated with depressive and GAD symptoms. In addition to the mean levels of affect, it is important to study other emotion dynamic indices such as NA instability, as these offer a more nuanced view of underlying emotion dysregulation processes. This could, in the long-term, help tailor more specific prevention and intervention methods for mood and anxiety disorders.

Association between parental resource depletion and parent use of specific food parenting practices: An ecological momentary assessment study

The resource depletion model proposes that self-control is a limited resource that may become depleted after repeated use. This study aimed to improve our understanding of the correlates of resource depletion in parents, examine the association between resource depletion and use of coercive food parenting practices, and explore the relationship between resource depletion and stress. Children aged 5–9 and their parents (n = 631 dyads) were recruited from primary care clinics in a large metropolitan area in the United States in 2016–2019. Ecological momentary assessment was carried out over seven days with parents. Frequency tabulations and descriptive statistics were calculated to examine the overall, between-participant, and within-participant frequency of resource depletion, stress, and coercive food parenting practices. Resource depletion was higher among mothers (as compared to fathers) and native born participants (as compared to immigrants). Resource depletion was found to decrease significantly with each increase in household income level and perceived co-parenting support was negatively associated with resource depletion. Greater resource depletion earlier in the day was positively associated with coercive food parenting practices (e.g., food restriction, pressure-to-eat) at dinner the same night. Further, prior day resource depletion was associated with greater pressure-to-eat the next day. Parents with lower chronic stress were found to engage in pressuring when experiencing higher depletion. Clinicians and public health professionals should be aware of the role the resource depletion can play in parent's use of specific food parenting practices and seek to provide parents with the support they need to manage the cognitive load they are experiencing.

Comparisons of Self-Report With Objective Measurements Suggest Faster Responding but Little Change in Response Quality Over Time in Ecological Momentary Assessment Studies.

Response times (RTs) to ecological momentary assessment (EMA) items often decrease after repeated EMA administration, but whether this is accompanied by lower response quality requires investigation. We examined the relationship between EMA item RTs and EMA response quality. In one data set, declining response quality was operationalized as decreasing correspondence over time between subjective and objective measures of blood glucose taken at the same time. In a second EMA study data set, declining response quality was operationalized as decreasing correspondence between subjective ratings of memory test performance and objective memory test scores. We assumed that measurement error in the objective measures did not increase across time, meaning that decreasing correspondence across days within a person could be attributed to lower response quality. RTs to EMA items decreased across study days, while no decrements in the mean response quality were observed. Decreasing EMA item RTs across study days did not appear problematic overall.

Momentary stress-induced food craving: An ecological momentary assessment study comparing perceived interpersonal and non-interpersonal stressors.

Daily-life stressors and food cravings are dynamic and vary within and across persons. Some evidence suggests interpersonal stressors increase appetite. However, little is known about the association of food craving with different types of stressors at the momentary level in the general population. We aimed to explore the momentary relationships between daily-life stressful events and food craving in a non-clinical community sample, and to compare the associations with food craving when the most stressful event was perceived as interpersonal versus non-interpersonal. We used ecological momentary assessment (EMA) to collect reports on the most stressful event, perceived stressor type, stressor appraisal, and food craving from 123 adults three times a day scheduled at fixed intervals over 10 days. Mixed effects random intercepts and slopes models examined the within- and between-person associations. Experiencing a stressor was significantly positively associated with within-person food craving at the same measurement. No differences in momentary food craving were found when the most stressful event was perceived as interpersonal or non-interpersonal (within-person level). However, frequently reporting the most stressful event as interpersonal (vs. non-interpersonal) was positively associated with food craving across the study (between-person level), particularly when the stressor was appraised as more unpleasant. Daily-life stressors were associated with momentary food craving. Individuals who generally perceived interpersonal stressors as their most stressful event tended to experience food cravings. Future research could further investigate the role of interpersonal stressors as a factor for overeating in daily life and the potential benefits of stress management in interventions.

Picturing self-harm: Investigating flash-forward mental imagery as a proximal and modifiable driver of non-suicidal self-injury.

Non-suicidal self-injury (NSSI) is theorized to be reinforced by its emotional consequences. Mental images of NSSI are commonly reported as occurring prior to NSSI. Based on the known functional properties of anticipatory mental imagery as an emotional and motivational amplifier, this study investigated whether NSSI mental imagery constitutes a proximal and dynamic mechanism underpinning NSSI risk. An intensive ecological momentary assessment (EMA) study was conducted to track the occurrence and characteristics of NSSI mental imagery alongside NSSI urge and behavior in naturalistic settings. A sample of N = 43 individuals aged 17 to 24 with a history of repetitive NSSI completed EMA surveys seven times a day for 14 days. Mental preoccupation in the form of NSSI mental imagery-based flash-forwards to the actions, bodily sensations, and emotional benefits of NSSI was found to occur when NSSI urge was high but not when urge was low. Critically, objective cross-panel analyses showed that higher frequencies of NSSI imagery occurrence predicted greater future NSSI urge and increased likelihood of acting on urge, over and above current urge. Mental imagery of NSSI is not simply an epiphenomenal by-product of NSSI urge and may constitute a dynamic and proximal novel intervention target.

Ecological Momentary Assessment of Weight Stigma and Eating Behavior in Everyday Life.

Weight stigma is widespread, but the existing literature on its harmful consequences remains largely limited to lab-based experiments and large-scale longitudinal designs. The purpose of this study was to understand how weight stigma unfolds in everyday life, and whether it predicts increased eating behavior. In this event-contingent ecological momentary assessment study, 91 participants reported every time they experienced weight stigma and documented whether they ate, how much they ate, and what they ate. These reports were compared against a timepoint when they did not experience stigma. Participants reported a wide variety of stigmatizing events from a variety of sources, with the most common ones being the self, strangers, the media, and family. Multilevel models showed that participants were no more likely to eat post-stigma (vs. the comparison point), but if they did eat, they ate more servings of food (on average consuming 1.45 more servings, or 45% more). Moderation analyses indicated that this effect was amplified for men versus women. Experiencing weight stigma appears to beget behavioral changes, potentially driving future weight gain, placing individuals at ever more risk for further stigmatization.

The Associations among Perceived Courtesy Stigma, Health and Social Behaviours in Family Members and Friends of People Who Use Substances: An Ecological Momentary Assessment Study

Background: The stigma and discrimination experienced by individuals with an alcohol/substance use disorder often extends to the family members and friends who provide care, which is known as courtesy stigma. This courtesy stigma can lead to isolation, poor mental health and might impact the quality-of-care these individuals provide. The aim of this study was to examine the frequency of experienced courtesy stigma/discrimination in individuals in a family support service for a loved one’s substance use, and to examine any cross-sectional associations with changes in mood, health- and social-related outcomes. Methods: Thirty-six individuals (25 female) with a mean age of 51.91 years took part in an ecological momentary assessment study in which the experience of courtesy stigma/discrimination and measures of mood, health (e.g. alcohol use, nicotine use, healthy eating, sleep, physical activity) and social connections were taken 3 times per day for fourteen days. Results: Across 1029 competed assessments (compliance ∼68%), there were 122 (∼11%) reports of courtesy stigma/discrimination. The most common sources of stigma/discrimination were from family members (∼43% of occurrences) and friends (∼31% of occurrences). Experiencing this stigma/discrimination was associated with increases in alcohol and nicotine use, as well as reductions in healthy eating, physical activity, sleep, social connections, and mood. Conclusions: The experience of courtesy stigma/discrimination was common in a sample of individual’s who support a loved one with alcohol or substance use disorder. These experiences are associated with changes in health and social behaviors and may lead to a poorer quality of care.
