Emotional well-being in Charles Bonnet syndrome: exploring associations with negative affect, loneliness and quality of life.

Background: Charles Bonnet syndrome (CBS) is a condition characterised by the occurrence of vivid and complex visual hallucinations in individuals with visual impairment. Objective: To explore the relationship between emotional distress and the perceived impact of CBS symptoms on participants' lives. We tested the hypothesis that heightened negative affect was associated with a more negative appraisal of CBS symptoms, increased self-reported loneliness, and poorer quality of life (QOL). Design: Cross-sectional. Methods: Participants recruited predominantly via vision-related charities rated their hallucinations and their impact on a Likert scale. Loneliness and negative affect were assessed with the Three-Item Loneliness Scale and Positive and Negative Affect Schedule. Health index (EQ-5D-3L) and vision-related QOL (VF-9) were also assessed. Correlation analysis and multi-variable regression determined the relation between survey responses. Results: The majority of 126 respondents (81%) were aged 65+ years and 84% reported active CBS symptoms. Fifty-five percent of respondents rated impact of CBS as negative and no-one rated the impact as 'very pleasant'. A statistically significant correlation was found between impact of CBS and negative affect (p ⩽ 0.001; rho = -0.34) and impact of CBS and loneliness (p = 0.017; rho = -0.21). The relation between negative affect and CBS impact remained statistically significant when accounting for the impact of loneliness and the relationship between loneliness and CBS effect (p = 0.002, adj R 2 = 0.1). A statistically significant correlation between loneliness and negative affect (p ⩽ 0.001; rho = 0.55) was also found. Conclusion: Respondents experiencing negative emotions were more likely to perceive the impact of CBS symptoms as negative and report greater feelings of loneliness. Negative affect is an important consideration when assessing people with CBS.

Understanding the impact of visual hallucinations in Charles Bonnet syndrome Charles Bonnet Syndrome (CBS) is a condition where people with vision problems experience vivid and complex visual hallucinations. In this study, we wanted to see how feeling upset or lonely might affect how people with CBS view their symptoms. We asked 126 adults, most of whom were over 65 years old, about their hallucinations and how they felt about them. We also asked about feelings of loneliness and general emotional well-being. We found that the more negative emotions people felt, the more they tended to see their CBS symptoms in a negative light and feel lonelier. This suggests that understanding and addressing negative emotions is crucial when helping people with CBS.

Attention control mediates the relationship between mental imagery vividness and emotion regulation.

Contradictory findings suggest mental imagery may both exacerbate and protect against negative affect. We aimed to reconcile these contradictory findings by considering individual differences (N=989) in imagery vividness, attention control, resilience, emotion regulation strategy, and negative affect (depressive, anxious, and posttraumatic stress symptomology). We hypothesized that attention control would mediate relationships between imagery vividness and emotion regulation strategy use, and psychopathology symptomology. Results revealed that imagery vividness, as mediated by attention control, predicted greater levels of healthy reappraisal and deleterious rumination. Attention control also mediated negative relationships between imagery vividness and catastrophizing, self-blame, and psychopathology symptomology. An exploratory latent structural equation model revealed that imagery vividness and attention control aggregated positively with reappraisal and resilience scores. The present investigation suggests an adaptive function of imagery vividness via the indirect effects of attention control, facilitating adaptive emotion regulation and limiting maladaptive strategy use, thereby protecting against negative affect.

Affective dynamics surrounding craving, non-heavy alcohol use and binge drinking in female patients with alcohol use disorder and controls: An experience sampling method study.

BACKGROUND AND AIMS: Studies show that higher levels of positive affect (PA) and lower levels of negative affect (NA) are related to craving and alcohol consumption at a daily level in men, but little is known on these associations at a momentary level, and whether they are present in women. This study measured the dynamics of within-person NA and PA surrounding craving, non-heavy alcohol use and binge drinking in women with alcohol use disorder (AUD) and female controls without AUD. METHODS: 53 female patients with AUD and 75 female controls, all recruited in Belgium, were included in an experience sampling study where they reported on momentary NA, PA, craving and alcohol use in daily life over a period of 12 months. Assessments occurred eight times a day on Thursdays, Fridays and Saturdays in seven bursts of three weeks. RESULTS: Within-person NA at a previous assessment (t-1) predicted craving at the current assessment (t0) in patients with AUD in a positive linear [ß = 0.043; 95% confidence interval (CI) = 0.002, 0.057; P = 0.041] and quadratic fashion (ß = 0.034; CI = 0.011, 0.057; P = 0.004). Within-person PA at t-1 predicted craving at t0 in patients with AUD with a positive quadratic relation (ß = 0.042; CI = 0.08, 0.065; P < 0.001). Within-person NA at t-1 negatively predicted non-heavy alcohol use at t0 in a linear fashion in controls (ß = -0.495; CI = -0.677, -0.312; P < 0.001) and patients with AUD (ß = -0.276; CI = -0.421, -0.132; P < 0.001). Within-person PA at t-1 significantly predicted non-heavy alcohol use at t0 with a positive linear term (ß = 0.470; CI = 0.329, 0.610; P < 0.001) in controls, but with a positive linear term (ß = 0.399; CI = 0.260, 0.454; P < 0.001) and a positive quadratic term (ß = 0.203; CI = 0.060, 0.347; P = 0.003) in patients with AUD. Within-person NA at t-1 predicted binge drinking at t0 in patients with AUD with a significant quadratic term (ß = 0.236; CI = 0.060, 0.412; P = 0.008), but not for controls. Within-person PA at t-1 predicted binge drinking at t0 in patients with AUD with a significant quadratic term (ß = 0.378; CI = 0.215, 0.542; P < 0.001), and this was also the case for controls (ß = 0.487; CI = 0.158, 0.770; P < 0.001). Non-heavy alcohol use at t0 predicted lower levels of NA at t+1 in both patients with AUD (ß = -0.161; SE = 0.044; CI = -0.248, 0.074; P = 0.001) and controls (ß = -0.114; CI = -0.198, -0.029; P = 0.010). Non-heavy alcohol use at t0 also predicted higher levels of PA at t+1 in both patients with AUD (ß = 0.181; CI = 0.088, 0.274; P < 0.001) and controls (ß = 0.189; CI = 0.101, 0.278; P < 0.001). CONCLUSIONS: The momentary relation between affect and craving or alcohol use seems to be non-linear in female patients with alcohol use disorder, whereby a worse mood predicts subsequent alcohol use, though more for binge drinking than for non-heavy alcohol use.

The emotion of gratitude as a mediator between subjective happiness, positive and negative affect and satisfaction with life in Spanish adults / La emoción de gratitud como mediadora entre la felicidad subjetiva, el afecto positivo y negativo y la satisfacción con la vida en adultos españoles

El presente estudio investigó si la satisfacción con la vida se predice a partir de la felicidad subjetiva, afectos positivos y negativos, alteración psicológica y emociones de gratitud y si la emoción de gratitud está mediando la relación con la felicidad subjetiva, los afectos y la satisfacción con la vida. Se hicieron correlación de Pearson, pruebas de regresión lineal múltiple y modelos de mediación en una muestra de 1537 adultos españoles, 73.6% mujeres y 26.4% hombres, edad 18-88 años (M = 42.56 años; DT = 16.29). Se halló que las emociones de gratitud median la relación entre felicidad subjetiva y satisfacción con la vida y entre los afectos positivos y la satisfacción con la vida. Los afectos positivos son los que más se relacionan con la satisfacción con la vida, seguidos por la felicidad subjetiva y las emociones de gratitud. Los hombres están más satisfechos con la vida cuando sienten menos afecto negativo. Además, las emociones de gratitud median la relación entre felicidad subjetiva y satisfacción con la vida y entre los afectos positivos y la satisfacción con la vida. La diferencia principal radica en que las emociones de gratitud son más fuertes en las mujeres que en los hombres.(AU)

This study aims to examine the predictability of satisfaction with life on the basis of subjective happiness, positive and negative affect, psy-chological disturbance and emotion of gratitude. It also seeks to assess whether the emotion of gratitude is a mediating variable withsubjective happiness, affect, and satisfaction with life. Statistical analyses of Pearson'scorrelation, multiple linear regression tests, and mediation models were conducted on asample of 1537 Spanish adults, 73.6% were females, 26.4% males, age between 18-88 yearsold (M = 42.56; SD = 16.29). The emo-tions of gratitude were found to mediate therelationship between subjec-tive happiness and satisfaction with life and between positiveaffect and satisfaction with life. Of the variables studied, positive affect is the most related tosatisfaction with life, followed by subjective happiness and emo-tions of gratitude. Maleparticipants are more satisfied with life when they feel the less negative affect. Regardingmediation models, emotions of grat-itude mediate the relationship between subjectivehappiness and satisfac-tion with life and between positive affect and satisfaction with life. Themaindifferenceis thatemotions of gratitudearestronger infemalesthan in males.(AU)

Unfeeling or Uncontrolled? PCL-R Subfactor-Specific Anomalies in Psychological Processing During Criminal Behavior.

Psychopathy has been linked to insensitivity to negative affect as well as to a self-regulatory deficit. However, studies on these associations rarely involve real-life behavioral data. Using a theory-based content analysis of offense descriptions in criminal verdicts, the affective and regulatory processes that male German prison inmates (N = 109) displayed during criminal norm-violations were coded. Their PCL-R scores were split up into the interpersonal-affective (F1) and the lifestyle-antisocial (F2) factors. As expected, F1 was associated with positive (as opposed to negative) activation affect during criminal behavior (τ = .32, p < .001), while F2 was not. In contrast, F2 was associated with impulsive reactivity (τ = .14, p = .03), while F1 was not. No differential association was found with angry emotionality. Overall, the bifactorial nature of the PCL-R psychopathy construct seems to be reflected in psychological processing during real-life criminal behavior. This might indicate differential criminogenic processes.

BNST CRF receptor type 1 modulates mechanical hypersensitivity induced by adolescent alcohol exposure in adult female mice.

RATIONALE: Alcohol exposure during adolescence has been linked to long-lasting behavioral consequences, contributing to the development of alcohol use disorder. Negative affect and chronic pain during alcohol withdrawal are critical factors influencing problematic alcohol use and relapse. Our previous research demonstrated that adolescent intermittent ethanol (AIE) vapor exposure elicits sex-specific negative affect-like behavior in adult mice following stress exposure. Additionally, AIE induces persistent mechanical hypersensitivity, which is accompanied by increased activation of corticotropin-releasing factor receptor type 1 (CRFR1) neurons in the dorsolateral bed nucleus of the stria terminalis (dlBNST). OBJECTIVES: This study extends previous work by investigating plasma corticosterone levels and CRFR1 protein expression in the dlBNST following restraint stress exposure in adult mice with an AIE history. We also aim to explore the role of dlBNST CRFR1 signaling in mediating negative affect-like behavior and mechanical hypersensitivity. RESULTS: Female mice exhibited elevated plasma corticosterone levels compared to males following restraint stress. Moreover, females with AIE history showed higher expression of CRFR1 protein in the dlBNST compared to air controls. Antagonism of CRFR1 in the dlBNST blocked AIE-induced mechanical hypersensitivity in adult females but did not affect stress-induced negative affect-like behavior. In alcohol-naïve females, intra-dlBNST administration of a CRFR1 agonist induced mechanical hypersensitivity. CONCLUSIONS: These findings provide new insights into the neurobiological mechanisms underlying stress-induced negative affect and pain-related behavior, both influenced by a history of adolescent alcohol exposure. The results suggest that CRFR1 antagonists warrant further investigation for their potential in addressing alcohol-related chronic pain.

Vicarious heterosexism-based stress induces alcohol, nicotine, and cannabis craving and negative affect among sexual minority young adults: An experimental study.

Purpose: Sexual minority young adults are at increased risk for hazardous drinking and alcohol use disorder compared to heterosexual adults. Heterosexism-based stressors contribute and often explain inequities in alcohol outcomes. However, the extant research primarily relies on correlational designs, and often neglects the importance of alcohol craving, despite its foundational role in addiction. Leveraging a novel experimental mood induction paradigm, this study examined the effects of exposure to vicarious heterosexism-based stress on alcohol craving and negative affect among sexual minority young adults who drink heavily. We also examined its effects on cannabis and nicotine craving among participants who used cannabis and nicotine, respectively. Lastly, we examined moderating factors that could influence the impact of exposure to heterosexism-based stress on alcohol craving. Methods: Participants were 101 heavy drinking sexual minority young adults, ages 20-35 (M = 26.46 years old; SD = 3.49), recruited from the community (51.5% female sex assigned at birth; 76.3% cisgender; 51.5% plurisexual; and 42.6% racial and ethnic minorities). They completed three mood induction trials counterbalanced over three visits on different days: heterosexism stress, general stress, and neutral. Structured interviews assessed criteria for DSM-5 alcohol use disorder (AUD) and substance use, and self-report measures assessed lifetime traumatic stressors. Results: Most participants met criteria for past-year AUD (74.7%). Exposure to heterosexism stress produced more negative affect and substance craving than the neutral mood induction, even while controlling for demographic variables and lifetime exposure to traumatic and heterosexism stressors. Exposure to heterosexism-based stress had large effects on alcohol craving among participants who had greater drinking to cope motives and heterosexism-specific rejection sensitivity, whereas the effects were small for those who had lower drinking to cope motives and heterosexism-specific rejection sensitivity. Demographic, lifetime stress, prior alcohol use, and AUD symptom severity variables were not significant moderators. Greater substance craving induced by heterosexism-based stress in the laboratory was associated with greater recent and current substance use. Conclusions: This study findings show that vicarious exposure to heterosexism elicits negative mood and alcohol, cannabis, and nicotine craving among sexual minority young adults who engaged in heavy drinking. The effects for alcohol craving were largest among those who endorse high levels of drinking to cope motives and heterosexism-based rejection sensitivity. These findings have implications for oppression-based stress and motivational models of addiction.

The influence of infant temperamental negative affect and maternal depression on infant and maternal social positive engagement during the Still-Face procedure.

Positive mother-infant interactions are important for infant development. Both mother and infant characteristics, such as maternal depression and infant temperamental negative affect are risk factors for adverse mother-infant bonding and infant outcomes. Although these predictors have been researched individually, limited studies have considered them in concert. This study aimed to examine the role of infant age (6-, 9- and 12-months), infant temperamental negative affect, and maternal depression on maternal and infant social positive engagement during the Still-Face procedure. Participants were 85 ethnically-varied mother-infant dyads (44 % girls). Mothers responded to questionnaires, prior to attending the laboratory for the Still-Face procedure (i.e., a task involving a social stressor). Results showed a significant moderating relationship between infant age, infant temperamental negative affect, and maternal depression on infant social positive engagement. For 12-month-old infants, higher infant temperamental negative affect was found to be compounded by greater maternal depression symptoms resulting in significantly lower social positive engagement following a social stressor. This relationship was not found for younger infants. No predictors were associated with maternal social positive engagement. Results from this study contribute to the literature on infant wellbeing. Results highlight the importance of interventions that aim to reduce maternal depression symptoms, especially, as maternal depression may disproportionately influence 12-month-old infants who have negative temperament.

The Indirect Effects of Negative Affect Reduction Motives on the Relationship Between Sex and Severity of Problems When Trying to Quit Among Black Adults Who Smoke.

BACKGROUND: African American/Black (hereafter referred to as Black) persons who smoke constitute a tobacco disparities group in the United States. Within the Black population, female smokers experience a disproportionate percentage of these disparities and are less likely to quit cigarettes than their male counterparts. Two factors implicated in female smokers' relatively worse quit success are (1) motives to smoke to reduce negative affect and (2) expectancies that smoking will reduce negative affect. OBJECTIVES: The present study sought to test sex differences in these two clinically relevant cognitive constructs and evaluate the indirect effects of sex and severity of problems when trying to quit via smoking motives and expectancies for negative affect reduction among Black adults who smoke. Participants included 103 Black adults who smoke daily (72% male; Mage = 44.5 years, SD = 11.5 years). RESULTS: Results revealed sex differences in both negative affect reduction motives and expectancies, as well as a partial indirect effect for sex on the severity of problems when trying to quit through negative affect reduction motives (a1b1 = 0.18, 95% CI [0.04, 0.38]) but not negative affect reduction expectancies (a2b2 = -0.01, 95% CI [-0.11, 0.09]) in a simultaneous model of indirect effects. CONCLUSIONS: These findings shed light on the complex relationship between race, sex, and severity of problems when trying to quit, particularly when complicated by smoking motives and expectancies. Current data should be considered when developing sex-specific, tailored smoking cessation interventions for Black women.

A within-person test of the metacognitive model: Daily dynamics between metacognitive beliefs, metacognitive strategies, and negative affect.

The metacognitive model of psychological disorders highlights that emotional distress is maintained by metacognitive strategies, which are related to underlying metacognitive beliefs. Considerable empirical evidence has supported the role of metacognitions in psychopathology, but few studies have examined the suggested links between metacognitive beliefs, metacognitive strategies, and symptoms within individuals. Within-person effects provide better empirical tests of theory-based hypotheses derived from clinical models as they relate to change at the individual level. Thus, the current study sought to test central predictions from the metacognitive model at the within-person level using Dynamic Structural Equation Modelling (DSEM). A sample of 222 participants gathered at convenience participated in a 26-day long assessment period where they reported daily measures of metacognitive beliefs, metacognitive strategies, and negative affect. Temporal precedence and bidirectional relations between the variables, and the possible day-to-day and within days mediation role of metacognitive strategies between metacognitive beliefs and negative affect, were tested. When controlling for previous days effects, metacognitions and negative affect (but not metacognitive strategies) predicted each other the next day, showing a reciprocal relationship. However, metacognitive strategies were significant mediators between metacognitions and negative affect within days and day-to-day. Implications and future directions based on these findings are discussed.

Linking Daily Victimization to Daily Affect Among Adolescents: The Mediating Role of Sleep Quality and Disturbance.

Bullying victimization is prevalent among adolescents and often linked to emotional problems. Prior studies have been focused on the concurrent or longitudinal associations between bullying victimization and emotional problems, but the daily associations and the underlying mechanisms remain unclear. Implementing daily diary method, the study aimed to examine the links between daily victimization and positive and negative affect as well as the mediating role of sleep quality and disturbance. A total of 265 Chinese adolescents (Mage = 11.65, SD = 0.74; 32.80% females) participated in this study and completed 7-day daily diaries on bullying victimization (traditional and cyber victimization), sleep quality and disturbance, and affect. As hypothesized, at the between-person level, sleep disturbance mediated the relationships between both traditional and cyber victimization and subsequent negative affect. At the within-person level, sleep quality mediated the pathway between traditional victimization and next-day negative affect; furthermore, sleep disturbance mediated the pathway between traditional victimization and positive affect the following day. These findings highlight the mediating roles of sleep quality and sleep disturbance in the relationships between stressful victimizing experiences and emotional problems and also provide novel insights into these associations.

Associations of luteal phase changes in vagally mediated heart rate variability with premenstrual emotional changes.

BACKGROUND: A recent meta-analysis revealed that vagally mediated heart rate variability (vmHRV; a biomarker of emotion regulation capacity) significantly decreases in the luteal phase of the menstrual cycle. As two follow-up studies suggest, these vmHRV decreases are driven primarily by increased luteal progesterone (P4). However, analyses also revealed significant interindividual differences in vmHRV reactivity to the cycle, which is in line with longstanding evidence for interindividual differences in mood sensitivity to the cycle. The present study begins to investigate whether these interindividual differences in vmHRV cyclicity can explain who is at higher risk of showing premenstrual emotional changes. We expected a greater degree of midluteal vmHRV decrease to be predictive of a greater premenstrual increase in negative affect. METHODS: We conducted an observational study with a naturally cycling community sample (N = 31, M = 26.03 years). Over a span of six weeks, participants completed (a) daily ratings of negative affect and (b) counterbalanced lab visits in their ovulatory, midluteal, and perimenstrual phases. Lab visits were scheduled based on positive ovulation tests and included assessments of baseline vmHRV and salivary ovarian steroid levels. RESULTS: In line with previous research, multilevel models suggest that most of the sample shows ovulatory-to-midluteal vmHRV decreases which, however, were not associated with premenstrual emotional changes. Interestingly, it was only the subgroup with luteal increases in vmHRV whose negative affect markedly worsened premenstrually and improved postmenstrually. CONCLUSION: The present study begins to investigate cyclical changes in vmHRV as a potential biomarker of mood sensitivity to the menstrual cycle. The results demonstrate a higher level of complexity in these associations than initially expected, given that only atypical midluteal increases in vmHRV are associated with greater premenstrual negative affect. Potential underlying mechanisms are discussed, among those the possibility that luteal vmHRV increases index compensatory efforts to regulate emotion in those with greater premenstrual negative affect. However, future studies with larger and clinical samples and more granular vmHRV assessments should build on these findings and further explore associations between vmHRV cyclicity and menstrually related mood changes.

Temporal Dynamics of Positive and Negative Affect in Adolescents: Associations with Depressive Disorders and Risk.

Alterations in dynamic affective processes are associated with dysregulated affect and depression. Although depression is often associated with heightened inertia (i.e., greater moment-to-moment correlation) and variability (i.e., larger departures from typical levels) of affect in adults, less is known about whether altered affect dynamics are present in youth at risk for depression. This study investigated the association of clinical depression and depression risk with the inertia and variability of positive and negative affect in a sample of youth at varying risk for depression. Our sample included 147 adolescents aged 14 to 17, categorized into three groups: never-depressed lower-risk, never-depressed higher-risk (based on maternal history of depression), and currently depressed adolescents. Adolescents completed ecological momentary assessments of positive and negative affect up to seven times per day for a week. Multilevel models and ANOVAs were used to examine associations of affective inertia and variability with adolescent depression and risk based on maternal history, controlling for average affect. Depressed adolescents showed more inert and diminished positive affect, and more variable and elevated negative affect compared to lower- and higher-risk youth, though associations attenuated after controlling for average affect. No differences were identified between never-depressed higher-risk and lower-risk youth. Additional longitudinal studies are needed to evaluate whether altered affect dynamics in daily life precede depression onset to understand their utility for developing preventive interventions.

Negative Affect, Sensation Seeking, and Adolescent Substance Use Development: The Moderating Role of Executive Function.

It is unknown how the Addictions Neuroclinical Assessment markers-negative affect, sensation seeking, and executive function-contribute to substance use development. This study examined whether associations of negative affect and sensation seeking with substance use vary by executive function. Participants were 167 adolescents (47% female) who participated annually for four years (Mage = 14.07, SDage = 0.54 at Time 1). There were within-person bidirectional associations between higher negative affect and higher substance use for adolescents with lower executive function. Adolescents with higher sensation seeking at age 14 exhibited increasing substance use trajectories from age 14 to 17, regardless of executive function level. Negative affect and substance use influence each other within individuals, whereas sensation seeking predicts substance use between individuals.

BNST GluN2D-containing NMDARs contribute to ethanol intake but not negative affective behaviors in female mice.

BACKGROUND: Alcohol use disorder (AUD) is a chronic, relapsing disease, highly comorbid with anxiety and depression. The bed nucleus of the stria terminalis (BNST) and Crh+ neurons in this region play a key role in chronic ethanol-induced increases in volitional intake, hypothesized to be driven by emergent negative affective behaviors. Excitatory N-methyl-d-aspartate receptors (NMDARs) are a major target of ethanol, and chronic ethanol exposure has been shown to regulate NMDAR function and expression. Specifically, GluN2D subunit-containing NMDARs have emerged as a target of interest due to their limited distribution and potential roles in affective behavior. METHODS: Male and female mice underwent a home cage chronic drinking forced abstinence model (CDFA) to assess the impact of 1 day or 2 weeks of ethanol abstinence on BNST synaptic transmission and BNST Grin gene expression. Constitutive and conditional BNST GluN2D knockout mice were used to assess the impact of GluN2D deletion on continuous access ethanol intake as well as negative affect behaviors, using the open field, elevated zero maze, and forced swim tasks. RESULTS: We report here that excitatory transmission undergoes time-dependent upregulation in BNST Crh+ cells. Further, knockdown of dorsal BNST (dBNST) GluN2D expression significantly decreases ethanol intake in female, but not male, mice. While BNST Grin2b expression was significantly increased in protracted abstinence following CDFA, no differences in Grin2d expression were observed in the dBNST or dBNST Crh+ neurons. Finally, we find that deletion of GluN2D fails to alter negative affect in ethanol-naïve female mice. CONCLUSIONS: These data suggest a role for BNST GluN2D-containing NMDARs in ethanol drinking but not ethanol abstinence, highlighting sex differences and behavioral specificity. Overall, these data further suggest roles for BNST synaptic signaling in volitional ethanol intake that are partially independent of actions on affective behavior.

Further Examining Positive Affect in Relation to Worry: A Synergistic Effect Between Positive Affect Expressivity and Proneness to Positive Affect.

There is emerging interest in understanding positive affect dysfunction in relation to anxiety, including worry. This set of two studies examined the association between the inhibition of affect expression (general affect expressivity in Study 1, positive affect expressivity in Study 2) and worry, with a particular interest in the moderating role of proneness to experience positive affect. Subjects were US-residing adults (Study 1 N = 502, Study 2 N = 250) who were recruited through a crowdsourcing website and completed self-report measures of study variables. Moderated regression was used to examine study predictions that affect expression would negatively correlate with worry when coupled with diminished positive affect. Proneness toward negative affect was included as a covariate within multivariate analyses. An interactive effect between affect expressivity and positive affect was supported in Study 2 (positive affect expressivity) but not Study 1 (general affect expressivity) in relation to worry. A diminished tendency to express positive affect was associated with greater worry when coupled with less positive affect. Study results and future directions are discussed in terms of the potential emotion-regulatory functions of positive affect expressivity as it relates to worry.

Ecological momentary assessment of the unique effects of trait worry on daily negative emotionality: does arousal matter?

Worry proneness is a transdiagnostic trait that predicts increased negative affect (NA), potentially in the service of preventing negative emotional contrasts. Although discrete types of NA vary along the dimension of arousal, the extent to which trait worry predicts high vs. low arousal forms of NA in daily life is unclear. This distinction has important implications for conceptualising how worry may perturb adaptive emotionality in various disorders. The present study (not pre-registered) aimed to isolate the effects of trait worry on high (N = 88) and low (N = 122) arousal NA in daily life using ecological momentary assessment while controlling for potential physical and psychological confounds. Participants were assessed for trait worry and depressive symptoms at baseline then reported their affect, heart rate, and exercise three times per day for one week. Multilevel models revealed that trait worry predicted both increased high and low arousal NA after controlling for momentary heart rate, daily exercise, and depression. In contrast, baseline depressive symptoms only predicted low arousal NA in daily life. Findings support the contrast avoidance model of worry and suggest that worry is linked to increased state NA in daily life, independent of arousal.

Experiential Avoidance During Mealtimes Among Individuals With Eating Disorders.

The relationship between negative emotions and avoidance is widely theorized as a bidirectional cycle implicated in a range of psychopathology. Historically, research on this cycle has examined one type of negative emotion: anxiety. Yet, a broader range of internal experiences may be implicated in the maintenance of unhealthy avoidance cycles in psychopathology. This study examines prospective relationships among anxiety, guilt, physical discomfort, and experiential avoidance during mealtimes for individuals with eating disorders (EDs). Participants (N = 108) completed ecological momentary assessments four times a day for 25 days. We computed multilevel models to examine between- and within-person effects of negative emotions and physical discomfort on experiential avoidance. When including guilt and anxiety in one model, guilt, but not anxiety, explained the significant variance in experiential avoidance at the next meal. Mealtime physical discomfort and experiential avoidance evidenced reciprocal prospective relationships. Future research should test whether interventions targeting experiential avoidance and physical discomfort at mealtimes disrupt guilt.

What is a compassionate face? Avoided negative affect explains differences between U.S. Americans and Chinese.

While a compassionate face for Germans mirrors others' suffering, for U.S. Americans, a compassionate face is one that expresses a slight smile, partly because U.S. Americans want to avoid feeling negative ("avoided negative affect"; ANA) more than do Germans. The present work examines what people in a non-WEIRD (i.e. Chinese) cultural context think a compassionate face looks like. Additionally, it investigates whether an individually-measured cultural variable (i.e. ANA) can explain differences in conceptualisations of compassion between Chinese and U.S. Americans. Participants in China and the U.S. selected the face that most resembles a compassionate face in a reverse correlation task and completed a measure of ANA. As predicted, Chinese mental representations of a compassionate face included more sadness and less happiness compared to U.S. American mental representations of a compassionate face, and Chinese participants wanted to avoid feeling negative less than did U.S. Americans. Finally, ANA mediated the cultural differences in conceptualisations of compassion. We discuss how ANA and conceptualisations of compassion might be related to how people view the experience versus the expression of different emotions. This work has important implications for therapeutic settings and the meaning of compassion in an increasingly globalised and connected world.

Time-Dependent Effects of Altered Prebedtime Light Exposure in Enclosed Spaces on Sleep Performance Associated with Human States.

Purpose: Exposure to artificial light influences human performance, which is essential for maintaining healthy work and sleep. However, existing research has not explored the intrinsic links between sleep performance and human states over time under prebedtime light exposure interventions (LEIs). Methods: To investigate the time-dependent effects of altered prebedtime light exposure, four LEI groupings (#L1 - #L4) and a Time factor (D8, D9, and D10) were chosen for sleep experiments in enclosed spaces. Forty-eight young adults recruited were available for data analysis. Subjective alertness (SA), negative affect (NA), subjective sleep, and objective sleep were measured via the Karolinska Sleepiness Scale, Positive and Negative Affect Schedule, Next-day Self-assessment Sleep Quality, and joint assessment of wrist actigraphy and sleep diaries, respectively. Statistical analysis was used for the effects of light exposure on the human states (corresponding to the SA and NA) and sleep performance, while the process model helped construct the associations between the two. Results: The statistical effects revealed that the Time had a significant main effect on subjective sleep and changes in prebedtime alertness; the LEI had a significant main effect only on sleep onset latency (SOL). After undergoing altered prebedtime light exposure, the mean SA increased at prebedtime of D9 (p = 0.022) and D10 (p = 0.044); No significant effect on the NA was observed; Mean subjective sleep had a significant increase from D8 to D10. Moreover, five actigraphy-estimated sleep parameters were interrelated. In light of this, a chained pathway relationship was identified. The SOL played a mediating predictor between prebedtime state and objective sleep, which was linked to the awakening state through subjective sleep. Conclusion: Our study suggests that time-dependent effects of altered prebedtime light exposure on sleep performance are associated with human states at prebedtime and awakening, with implications for its prediction of sleep health.
