Affective economies in crowdfunding for cancer.

Cancer patients and survivors in the United States are increasingly likely to use online crowdfunding as a means of offsetting the expenses associated with their medical care. This practice of making an online appeal for support to a broad public audience constitutes an inadvertent form of informal emotional labor for its practitioners-labor in which striking the right affective notes in one's appeal is believed to be critical to fundraising outcomes. Drawing on ethnographic interviews, we suggest that crowdfunding produces an array of complex, often contradictory sentiments and narrative incentives for cancer patients and survivors-ultimately transforming the experience of serious illness.

Assessment of affective dysregulation in children: development and evaluation of a semi-structured interview for parents and for children.

BACKGROUND: Children with affective dysregulation (AD) show an excessive reactivity to emotionally positive or negative stimuli, typically manifesting in chronic irritability, severe temper tantrums, and sudden mood swings. AD shows a large overlap with externalizing and internalizing disorders. Given its transdiagnostic nature, AD cannot be reliably and validly captured only by diagnostic categories such as disruptive mood dysregulation disorder (DMDD). Therefore, this study aimed to evaluate two semi-structured clinical interviews-one for parents and one for children. METHODS: Both interviews were developed based on existing measures that capture particular aspects of AD. We analyzed internal consistencies and interrater agreement to evaluate their reliability. Furthermore, we analyzed factor loadings in an exploratory factor analysis, differences in interview scores between children with and without co-occurring internalizing and externalizing disorders, and associations with other measures of AD and of AD-related constructs. The evaluation was performed in a screened community sample of children aged 8-12 years (n = 445). Interrater reliability was additionally analyzed in an outpatient sample of children aged 8-12 years (n = 27). RESULTS: Overall, internal consistency was acceptable to good. In both samples, we found moderate to excellent interrater reliability on a dimensional level. Interrater agreement for the dichotomous diagnosis DMDD was substantial to perfect. In the exploratory factor analysis, almost all factor loadings were acceptable. Children with a diagnosis of disruptive disorder, attention-deficit/hyperactivity disorder, or any disorder (disruptive disorder, attention-deficit/hyperactivity disorder, and depressive disorder) showed higher scores on the DADYS interviews than children without these disorders. The correlation analyses revealed the strongest associations with other measures of AD and measures of AD-specific functional impairment. Moreover, we found moderate to very large associations with internalizing and externalizing symptoms and moderate to large associations with emotion regulation strategies and health-related quality of life. CONCLUSIONS: The analyses of internal consistency and interrater agreement support the reliability of both clinical interviews. Furthermore, exploratory factor analysis, discriminant analyses, and correlation analyses support the interviews' factorial, discriminant, concurrent, convergent, and divergent validity. The interviews might thus contribute to the reliable and valid identification of children with AD and the assessment of treatment responses.

How personnel diversity and affective bonds affect performance-based financing: a moderator analysis of a difference-in-difference estimator.

To spur improvement in health-care service quality and quantity, performance-based financing (PBF) is an increasingly common policy tool, especially in low- and middle-income countries. This study examines how personnel diversity and affective bonds in primary care clinics affect their ability to improve care quality in PBF arrangements. Leveraging data from a large-scale matched PBF intervention in Tajikistan including 208 primary care clinics, we examined how measures of personnel diversity (position and tenure variety) and affective bonds (mutual support and group pride) were associated with changes in the level and variability of clinical knowledge (diagnostic accuracy of 878 clinical vignettes) and care processes (completion of checklist items in 2485 instances of direct observations). We interacted the explanatory variables with exposure to PBF in cluster-robust, linear regressions to assess how these explanatory variables moderated the PBF treatment's association with clinical knowledge and care process improvements. Providers and facilities with higher group pride exhibited higher care process improvement (greater checklist item completion and lower variability of items completed). Personnel diversity and mutual support showed little significant associations with the outcomes. Organizational features of clinics exposed to PBF may help explain variation in outcomes and warrant further research and intervention in practice to identify and test opportunities to leverage them. Group pride may strengthen clinics' ability to improve care quality in PBF arrangements. Improving health-care facilities' pride may be an affordable and effective way to enhance health-care organization adaptation.

Employment equity groups' experience of inclusion and commitment to the CAF.

The Canadian Armed Forces (CAF) are subject to the Employment Equity Act, which requires federally regulated employers to identify and eliminate barriers to the employment of designated groups (women, Indigenous peoples, persons with disabilities (PwD), and racialized members), and establish short-term, numerical goals to address underrepresentation. Addressing employment barriers experienced by these equity seeking groups is one of the CAF's key priorities. The objective of this study is to examine group differences in feelings of inclusion (i.e., relatedness, organizational inclusion, and microaggressions) and retention-related measures (i.e., job satisfaction, affective commitment, and intentions to leave), the contribution of feelings of inclusion to retention measures, and the effect of numerical representation and number of marginalized identities on these concepts. We analyzed data from the 2022 Your Say Matters survey, which was administered to a representative sample of CAF members, with oversampling of under-represented groups. Respondents included 4,483 Regular Force members (30.9% response rate). The groups under study included Indigenous members, persons with disabilities, racialized members, women not part of another group (non-Indigenous, non-racialized, women without disabilities), and everyone else (non-Indigenous, non-racialized, not women, without disabilities). Our hypotheses were supported overall, such that groups with less representation in the CAF scored lower on inclusion measures than groups with more representation. The number of marginalized identities held by military members predicted the inclusion measures, but did not predict retention-related measures. There were some group differences on retention-related measures, such that women not part of another group scored more favorably than other designated groups, and racialized members scored more favorably than PwD and Indigenous members. Inclusion measures predicted job satisfaction, affective commitment, and intentions to leave equally for all groups studied, suggesting that feeling included is important for all.

Preliminary assessment of the psychometric properties of the Polish version of the Questionnaire to Assess Affective and Cognitive Empathy (QAACE) in Children.

BACKGROUND: This article reports the Polish adaptation of the Questionnaire to Assess Affective and Cognitive Empathy (QAACE) by Zoll and Enz - a multidimensional self-report questionnaire used to measure empathy in children aged 8-14. The QAACE is based on a two-factor cognitive-emotional model of empathy. It has a number of international adaptations and offers a convenient Polish-language tool for use with young children and adolescents. PARTICIPANTS AND PROCEDURE: The sample consisted of 677 children aged 8-13. The survey was conducted on school premises, during classes, by an appropriately prepared researcher. RESULTS: Confirmatory factor analysis revealed a good fitting measurement model representing the original underlying factor structure of the QAACE among Polish children. The reliability of the questionnaire as measured by Cronbach's α and McDonald's ω was good. The reliability of the scale as assessed by the test-retest method (after four weeks) was .80. We assessed the validity of the tool by analyzing the correlation of empathy with love and sadism. General empathy, as well as cognitive and affective empathy, is positively related to love. The hypothesis that sadism is significantly related to empathy was also partially confirmed. General empathy and affective empathy are negatively correlated with sadism, while there was no relationship between sadism and cognitive empathy. CONCLUSIONS: The questionnaire is the first widely available tool of this type to examine empathy and its components appropriate for children and adolescents in Poland. The questionnaire can be a useful screening test for detecting children's level of empathy.

Redefining cerebellar assessment: A comprehensive review of the cerebellum's cognitive and affective roles and the efficacy of CCAS scales.

Background: Emerging research expands our understanding of the cerebellum beyond motor control to include cognitive, emotional, and autonomic functions. This review examines the cerebellum's complex role, spotlighting Schmahmann's syndrome, or cerebellar cognitive affective syndrome (CCAS), which impairs executive functions, language, and spatial processing. It emphasizes advancements in diagnosing CCAS and the imperative of developing superior diagnostic tools for managing cerebellar pathologies effectively. Methods: A comprehensive literature search was performed using databases such as PubMed, OVID Embase, and OVID Medline. Using the keywords "cerebellar cognitive, affective syndrome" and "Schmahmann syndrome," the search was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines for systemic review, in which the selection process narrowed down an initial set of 54 articles to 12, focusing on the impact of the CCAS scale on diagnosing and understanding Schmahmann's syndrome. Results: The review's analysis confirms the cerebellum's roles in motor and cognitive functions and underscores the CCAS scale as a significant advancement in detecting cerebellar deficits, surpassing traditional assessments such as the mini-mental state examination and Montreal cognitive assessment. Conclusion: This review emphasizes the importance of understanding the cerebellum's involvement in cognition and emotion and the crucial role of the CCAS scale for identifying cerebellar impairments. It calls for better diagnostic tools to assess CCAS accurately and suggests enhancing the CCAS Scale to reflect cultural and educational diversity. This will improve the diagnosis and treatment of cerebellar disorders, promoting a comprehensive neurological perspective on the cerebellum's functions.

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

Introduction: 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. Methods: 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. Results: 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. Discussion: 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.

An affective assessment: incarnate biases in picture captions for autistic children.

Previous studies have explored cognitive disabilities experienced by autistic children between the ages of 2 and 5 who attend special schools. However, there is still debate regarding the onset, scope, and causes of these problems, particularly when considering incarnate biases that may arise from affective notions. Early affective issues could potentially be a key factor contributing to observing such biases in picture captions. In this study, we employed an affective approach-simultaneous observation and questionnaire-to investigate how incarnate biases impact picture caption activities. Specifically, we looked at the performances of autistic children across four grades: PreK, K1, K2, and K3. We found that autistic children across all grades demonstrated instances of incarnation-biased interpretations in picture captions, although K3 performed better than the other grades. Furthermore, their incarnate biases tended to be negative rather than positive in affection, depending on the level of activity involved. Ultimately, the sources of these incarnate biases may stem from three spheres: school, society, and family. Thus, it is essential to consider these factors when designing educational programs for children with autism. It highlights the potential dangers associated with negative biases in picture captions. Unlike previous studies that focused on identifying discrepancies in picture caption, our research suggests that over time, as we take into account the onset of incarnate biases from the three affective spheres discussed in this study, picture caption may improve among autistic children as their incarnate biases decrease.

Assessment of activation, intensity and duration of positive and negative emotions: psychometric properties of the Polish version of the Perth Emtional Reactivity Scale - Short Form.

BACKGROUND: The Perth Emotional Reactivity Scale - Short Form (PERS-S) is an 18-item self-report questionnaire that assesses emotional reactivity. The PERS-S measures activation, intensity, and duration of negative and positive emotions. The study aims to validate the Polish version of the PERS-S. Participants And Procedure: The study was performed on a sample of 675 people aged 18-80 (M = 28.88, SD = 13.17, 56.15% female). The factor structure and measurement invariance across gender, age and educational categories were verified with confirmatory factor analysis. Convergent and divergent validity were assessed based on the relationship between the PERS-S scale and the Emotional Reactivity scale taken from the Formal Characteristics of Behaviour-Temperament Inventory, the Emotion Regulation Questionnaire, the Perceived Stress Scale, the Warwick-Edinburgh Mental Wellbeing Scale and the Subjective Vitality Scale. RESULTS: The intended 6-factor model was an excellent fit for the data (CFI = .963; TLI = .953; RMSEA = .053, 90% CI [.046; .061]; SRMR = .057) and was invariant across gender, educational level and age groups. All PERS-S subscales correlated with another emotional reactivity questionnaire, stress, emotion regulation strategies, well-being and vitality as expected. The reliability was high for all subscales (α > .70); it was slightly lower only for the positive-activation subscale (α = .68). Due to gender differences in emotional reactivity traits, group norms (sten scale) were calculated separately for females and males. CONCLUSIONS: The Polish version of the PERS-S has strong psychometric properties. Its practical applications are discussed.

Influence of economics students' self-esteem on their academic engagement: The moderating role of gender.

This study investigated the moderating role of gender in the influence of Economics students' self-esteem on their academic engagement. This quantitative research used a descriptive cross-sectional survey design with a sample of 422 senior high school Economics students. The Academic Engagement and Self-Esteem Scales served as the instruments for data collection in this study. The data were analysed using partial least squares structural equation modelling (PLS-SEM). The study revealed that there was a statistically significant positive influence of Economics students' self-esteem on their academic engagement. Specifically, it was found out that self-esteem had a significant positive influence on academic affective, behavioural and cognitive engagement. Also, it was discovered that gender did not moderate the influence of students' self-esteem on their academic affective, behavioural and cognitive engagement. Therefore, it was recommended that parents, guardians and Economics teachers should guide students to improve upon their self-esteem since high self-esteem will lead to high academic engagement.

Daily life affective dynamics as transdiagnostic predictors of mental health symptoms: An ecological momentary assessment study.

BACKGROUND: Affective dynamics have been identified as a correlate of a broad span of mental health issues, making them key candidate transdiagnostic factors. However, there remains a lack of knowledge about which aspects of affective dynamics - especially as they manifest in the course of daily life - relate to a general risk for mental health issues versus specific symptoms. METHODS: We leverage an ecological momentary assessment (EMA) study design with four measures per day over a two-week period to explore how negative affect levels, inertia, lability, and reactivity to provocation and stress in the course of daily life relate to mental health symptoms in young adults (n = 256) in the domains of anxiety, depression, psychosis-like symptoms, behaviour problems, suicidality, and substance use. RESULTS: Dynamic structural equation modelling (DSEM) suggested that negative affect levels in daily life were associated with depression, anxiety, indirect and proactive aggression, psychosis, anxiety, and self-injury; negative affective lability was associated with depression, physical aggression, reactive aggression, suicidal ideation, and ADHD symptoms; negative affective inertia was associated with depression, anxiety, physical aggression, and cannabis use; and emotional reactivity to provocation was related to physical aggression. LIMITATIONS: The cross-sectional design, the limited span of mental health issues included, and the convenience nature and small size of the sample are limitations. CONCLUSIONS: Findings suggest that a subset of mental health symptoms have shared negative affective dynamics patterns. Longitudinal research is needed to rigorously examine the directionality of the effects underlying the association between affective dynamics and mental health issues.

Bi-directional associations of core affect and physical activity in adults with higher body weight: An ecological momentary assessment study.

Affect is known to be predictive of and enhanced by higher physical activity (PA) levels in the general population. This secondary analysis aimed to increase the understanding of the bi-directional relationship between PA and core affect (i.e. valence, energetic arousal, and calmness) among adults with higher body weight. Affect and PA were assessed in naturalistic settings via ecological momentary assessment using a mixed sampling scheme from 157 participants (body mass index: 32.99 ± 3.78 kg/m2). Multilevel models revealed that being more physically active in the 15 minutes prior to the assessment predicted an increase in energetic arousal and a decrease in calmness. Subsequently, feeling more energetic and agitated was associated with increased PA within the following 15 minutes. Valence (i.e. pleasure-displeasure) was not associated with PA nor predictive of subsequent PA. Digital PA interventions may target the enhancement of feelings of energy and present psychoeducation about these distinct psychological benefits.

The Association Between Linguistic Characteristics of Physicians' Communication and Their Economic Returns: Mixed Method Study.

BACKGROUND: Web-based health care has the potential to improve health care access and convenience for patients with limited mobility, but its success depends on active physician participation. The economic returns of internet-based health care initiatives are an important factor that can motivate physicians to continue their participation. Although several studies have examined the communication patterns and influences of web-based health consultations, the correlation between physicians' communication characteristics and their economic returns remains unexplored. OBJECTIVE: This study aims to investigate how the linguistic features of 2 modes of physician-patient communication, instrumental and affective, determine the physician's economic returns, measured by the honorarium their patients agree to pay per consultation. We also examined the moderating effects of communication media (web-based text messages and voice messages) and the compounding effects of different communication features on economic returns. METHODS: We collected 40,563 web-based consultations from 528 physicians across 4 disease specialties on a large, web-based health care platform in China. Communication features were extracted using linguistic inquiry and word count, and we used multivariable linear regression and K-means clustering to analyze the data. RESULTS: We found that the use of cognitive processing language (ie, words related to insight, causation, tentativeness, and certainty) in instrumental communication and positive emotion-related words in affective communication were positively associated with the economic returns of physicians. However, the extensive use of discrepancy-related words could generate adverse effects. We also found that the use of voice messages for service delivery magnified the effects of cognitive processing language but did not moderate the effects of affective processing language. The highest economic returns were associated with consultations in which the physicians used few expressions related to negative emotion; used more terms associated with positive emotions; and later, used instrumental communication language. CONCLUSIONS: Our study provides empirical evidence about the relationship between physicians' communication characteristics and their economic returns. It contributes to a better understanding of patient-physician interactions from a professional-client perspective and has practical implications for physicians and web-based health care platform executives.

Proxy measures for the assessment of psychotic and affective symptoms in studies using electronic health records.

BACKGROUND: There is a lack of standardised psychometric data in electronic health record (EHR)-based research. Proxy measures of symptom severity based on patients' clinical records may be useful surrogates in mental health EHR research. AIMS: This study aimed to validate proxy tools for the short versions of the Positive and Negative Syndrome Scale (PANSS-6), Young Mania Rating Scale (YMRS-6) and Montgomery-Åsberg Depression Rating Scale (MADRS-6). METHOD: A cross-sectional, multicentre study was conducted in a sample of 116 patients with first-episode psychosis from 12 public hospitals in Spain. Concordance between PANSS-6, YMRS-6 and MADRS-6 scores and their respective proxies was evaluated based on information from EHR clinical notes, using a variety of statistical procedures, including multivariate tests to adjust for potential confounders. Bootstrapping techniques were used for internal validation, and an independent cohort from the Treatment and Early Intervention in Psychosis Program (TIPP-Lausanne, Switzerland) for external validation. RESULTS: The proxy versions correlated strongly with their respective standardised scales (partial correlations ranged from 0.75 to 0.84) and had good accuracy and discriminatory power in distinguishing between patients in and not in remission (percentage of patients correctly classified ranged from 83.9 to 91.4% and bootstrapped optimism-corrected area under the receiver operating characteristic curve ranged from 0.76 to 0.89), with high interrater reliability (intraclass correlation coefficient of 0.81). The findings remained robust in the external validation data-set. CONCLUSIONS: The proxy instruments proposed for assessing psychotic and affective symptoms by reviewing EHR provide a feasible and reliable alternative to traditional structured psychometric procedures, and a promising methodology for real-world practice settings.

Influence of affective disorders on outcomes after suboccipital decompression for adult Chiari I malformation.

INTRODUCTION: Affective disorders (AD) have been shown to influence patient outcomes and healthcare resource utilization across several pathologies, though this relationship has not been described in patients with Chiari I malformations (CM-I). The aim of this study was to determine the impact of comorbid AD on postoperative events and healthcare resource utilization in adults following suboccipital decompression for CM-I. METHODS: A retrospective study was performed using the 2016-2019 National Inpatient Sample database. Adults who underwent suboccipital decompression for CM-I were identified using ICD-10-CM codes. Patients were stratified into two cohorts, those with AD and those without (No AD). Patient demographics, comorbidities, operative characteristics, perioperative adverse events (AEs), and healthcare resource utilization were assessed. Multivariate logistic regression analyses were used to identify independent predictors of prolonged length of stay (LOS), exorbitant admission costs, and non-routine discharge (NRD). RESULTS: A total of 3985 patients were identified, of which 2780 (69.8%) were in the No AD cohort and 1205 (30.2%) were in the AD cohort. Patient demographics were similar, except for a greater proportion of Female patients than the No AD cohort (p = 0.004). Prevalence of some comorbidities varied between cohorts, including obesity (p = 0.030), ADHD (p < 0.001), GERD (p < 0.001), smoking (p < 0.001), and chronic pulmonary disease (p < 0.001). The AD cohort had a greater proportion of patients with 1-2 (p < 0.001) or ≥ 3 comorbidities (p < 0.001) compared to the No AD cohort. A greater proportion of patients in the AD cohort presented with headache compared to the No AD cohort (p = 0.003). Incidence of syringomyelia was greater in the No AD cohort (p = 0.002). A greater proportion of patients in the No AD cohort underwent duraplasty only (without cervical laminectomy) compared to the AD cohort (p = 0.021). Healthcare resource utilization was similar between cohorts, with no significant differences in mean LOS (No AD: 3.78 ± 3.51 days vs. 3.68 ± 2.71 days, p = 0.659), NRD (No AD: 3.8% vs. AD: 5.4%, p = 0.260), or mean admission costs (No AD: $20,254 ± 14,023 vs. AD: $29,897 ± 22,586, p = 0.284). On multivariate analysis, AD was not independently associated with extended LOS [OR (95%CI): 1.09 (0.72-1.65), p = 0.669], increased hospital costs [OR (95%CI): 0.98 (0.63-1.52), p = 0.930], or NRD [OR (95%CI): 1.39 (0.65-2.96), p = 0.302]. CONCLUSION: Our study suggests that the presence of an AD may not have as much of an impact on postoperative events and healthcare resource utilization in adult patients undergoing Chiari decompression. Additional studies may be warranted to identify other potential implications that AD may have in other aspects of healthcare in this patient population.

Linking repeated subjective judgments and ConvNets for multimodal assessment of the immediate living environment.

The integration of alternative data extraction approaches for multimodal data, can significantly reduce modeling difficulties for the automatic location assessment. We develop a method for assessing the quality of the immediate living environment by incorporating human judgments as ground truth into a neural network for generating new synthetic data and testing the effects in surrogate hedonic models. We expect that the quality of the data will be less biased if the annotation is performed by multiple independent persons applying repeated trials which should reduce the overall error variance and lead to more robust results. Experimental results show that linking repeated subjective judgements and Deep Learning can reliably determine the quality scores and thus expand the range of information for the quality assessment. The presented method is not computationally intensive, can be performed repetitively and can also be easily adapted to machine learning approaches in a broader sense or be transferred to other use cases. Following aspects are essential for the implementation of the method:•Sufficient amount of representative data for human assessment.•Repeated assessment trials by individuals.•Confident derivation of the effect of human judgments on property price as an approbation for further generation of synthetic data.

Comparative Assessment of Physiological Responses to Emotional Elicitation by Auditory and Visual Stimuli.

The study of emotions through the analysis of the induced physiological responses gained increasing interest in the past decades. Emotion-related studies usually employ films or video clips, but these stimuli do not give the possibility to properly separate and assess the emotional content provided by sight or hearing in terms of physiological responses. In this study we have devised an experimental protocol to elicit emotions by using, separately and jointly, pictures and sounds from the widely used International Affective Pictures System and International Affective Digital Sounds databases. We processed galvanic skin response, electrocardiogram, blood volume pulse, pupillary signal and electroencephalogram from 21 subjects to extract both autonomic and central nervous system indices to assess physiological responses in relation to three types of stimulation: auditory, visual, and auditory/visual. Results show a higher galvanic skin response to sounds compared to images. Electrocardiogram and blood volume pulse show different trends between auditory and visual stimuli. The electroencephalographic signal reveals a greater attention paid by the subjects when listening to sounds compared to watching images. In conclusion, these results suggest that emotional responses increase during auditory stimulation at both central and peripheral levels, demonstrating the importance of sounds for emotion recognition experiments and also opening the possibility toward the extension of auditory stimuli in other fields of psychophysiology. Clinical and Translational Impact Statement- These findings corroborate auditory stimuli's importance in eliciting emotions, supporting their use in studying affective responses, e.g., mood disorder diagnosis, human-machine interaction, and emotional perception in pathology.

Investigating the day-level associations between affective variability and physical activity using ecological momentary assessment.

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

Objective assessment of autism spectrum disorder based on performance in structured interpersonal acting-out tasks with prosodic stability and variability.

In this study, we sought to objectively and quantitatively characterize the prosodic features of autism spectrum disorder (ASD) via the characteristics of prosody in a newly developed structured speech experiment. Male adults with high-functioning ASD and age/intelligence-matched men with typical development (TD) were asked to read 29 brief scripts aloud in response to preceding auditory stimuli. To investigate whether (1) highly structured acting-out tasks can uncover the prosodic of difference between those with ASD and TD, and (2) the prosodic stableness and flexibleness can be used for objective automatic assessment of ASD, we compared prosodic features such as fundamental frequency, intensity, and mora duration. The results indicate that individuals with ASD exhibit stable pitch registers or volume levels in some affective vocal-expression scenarios, such as those involving anger or sadness, compared with TD and those with TD. However, unstable prosody was observed in some timing control or emphasis tasks in the participants with ASD. Automatic classification of the ASD and TD groups using a support vector machine (SVM) with speech features exhibited an accuracy of 90.4%. A machine learning-based assessment of the degree of ASD core symptoms using support vector regression (SVR) also had good performance. These results may inform the development of a new easy-to-use assessment tool for ASD core symptoms using recorded audio signals.
