The utility of the psycholexical approach for identifying military core values: Illustrated in a sample of Swiss career officers and NCOs.

Values have always been a top priority in the military domains of leadership, training, ethical commitment, and psychological research. However, only a few studies have assessed value descriptors and their underlying dimensional structure in military organizations using an empirical psycholexical and factor analytical approach. This research project examined the structure of military values and derived core military values. Two studies were conducted in cooperation with the Swiss Armed Forces. In study 1, 25 military-specific value descriptors were identified based on a psycholexical analysis of military guidelines and in line with expert ratings by executive military leaders. In study 2, a questionnaire was filled out by a sample of 550 military professionals to capture their ratings of values as applied to everyday military decisions and actions. Principal component analysis in combination with Goldberg's top-down approach delivered five military value categories that reflect the military culture in Switzerland, characterized as (I) freedom, (II) social cohesion, (III) good soldiership, (IV) mutual respect, and (V) military conformity. Results are discussed in light of introducing a novel research approach to assessing the value structure and culture in military organizations.

Paragons of character-Character strengths and well-being of moral, creative, and religious exemplars.

OBJECTIVE: Which traits best describe individuals who are recognized as exemplary in different domains? And can self-rated positively valued personality traits distinguish such individuals from the general population? BACKGROUND: The study of exemplary individuals' personality traits traditionally focused on general and broad traits. Using character strengths, which are narrower and designed to describe desirable behavior, could provide new insights. METHOD: In this study, we examined 204 outstanding individuals-exemplars who received or were nominated for a public award recognizing their exemplary behavior (e.g., a Carnegie Rescuers Award; n = 119), individuals holding a patent (n = 62), and individuals living in a religious order (n = 23). We compared these exemplars to comparison samples matched based on demographic variables. All participants completed self-report questionnaires assessing character strengths and well-being (e.g., satisfaction with life). RESULTS: Results showed that the three groups of exemplars differed meaningfully in their character strengths and well-being from the matched comparison groups. Compared with matched counterparts, moral exemplars scored higher on the strengths related to the virtues of courage, humanity, and justice as well as the character strength of humility, creative exemplars scored higher on the character strengths of creativity and honesty, and religious exemplars scored higher on gratitude and spirituality. CONCLUSION: Overall, our findings suggest that character strengths are a useful framework for studying exemplary behavior.

Evaluation of a Study Protocol of the Application of Humor Interventions in Palliative Care Through a First Pilot Study.

Background: Humor and laughter might have an alleviating effect on pain threshold and enhance coping and building relationships. However, randomized controlled studies in palliative care have struggled with high percentages of attrition and missing values. Objectives: We aimed to evaluate a study protocol through a pilot study for the evaluation of a multistage humor intervention with psychological and physiological outcome parameters that may be applied successfully in a palliative care environment. Design: This pilot study utilized a pre-post design. The inclusion of a control group for the final study setting recruiting 120 patients is planned. Setting/Subjects: The study was a monocenter study in a clinic for palliative care in Germany. All patients were eligible for recruitment. Seven patients were recruited for the pilot study. Measurements: Interventions were developed using a humor training for psychiatric patients. Quantitative sensory testing for pain threshold testing and questionnaires on humor as a character trait, pain intensity, life satisfaction, and symptom burden were planned to be evaluated before and after three humor interventions. Results: The feasibility of the original study design was re-evaluated after pilot testing. Only two out of the seven patients were able to complete two interventions, requiring modification. Fewer questionnaires, less complex physiological testing, and reduction from three to two interventions were then planned. Conclusion: The initial planned research methodology must be adjusted for patients with high symptom burden. In the experimental group of the final study setting, the effects of one to two interventions will be evaluated measuring oxytocin levels in saliva and using standardized questionnaires to determine cheerfulness, life satisfaction and symptom burden, as well as assessing as-needed medication.

Toward a dynamic model of Gelotophobia: Social support, workplace bullying and stress are connected with diverging trajectories of life and job satisfaction among Gelotophobes.

Recent theoretical advances have grounded gelotophobia (Greek: gelos = laughter, phobos = fear) in a dynamic framework of causes, moderating factors, and consequences of the fear of being laughed at. This understanding corresponds to that of vulnerability and translates gelotophobia into a distinguishable pattern of lacking resources (i.e., misinterpretation of joy and laughter) that can result in negative consequences (e.g., reduced well-being and performance) if individuals have no access to further resources (e.g., social support) or are exposed to severe stressors (e.g., workplace bullying). Based on the panel data provided by the Swiss National Centre of Competence in Research LIVES (N = 2469 across six measurement intervals), this study takes the first step toward empirically testing this model's assumptions: First, we computed exemplary zero-order correlations and showed that gelotophobia was negatively connected with social support (resource) and life and job satisfaction (consequences) and positively connected with perceived stress, work stress, and workplace bullying (stressors). Second, we used longitudinal cluster analyses (KmL; k-means-longitudinal) and showed that the panel data can be clustered into three stable patterns of life and job satisfaction and that gelotophobia is primarily related to the two clusters marked by lower levels of satisfaction. Third, we computed partial correlations and showed that social support, perceived stress, and work stress (but not workplace bullying) can weaken or completely resolve gelotophobia's relationships with such diverging trajectories of life and job satisfaction. We concluded that seeing gelotophobia through the lens of vulnerability is useful and that such research warrants further attention using more dedicated, theoretically grounded projects.

Humour interventions for patients in palliative care-a randomized controlled trial.

PURPOSE: The effect of humour on end-of-life patients could be beneficial and is worth investigating. However, data on humour interventions for patients in palliative care are scarce. This study evaluated the effects of a humour intervention in a palliative care setting. METHODS: A two-step intervention was developed based on the humour habits programme by McGhee. Patients were assisted to remember funny episodes from their past and recognize humorous aspects of the present and encouraged to produce humour. The intervention and control group completed questionnaires on life satisfaction, cheerfulness, symptom burden, and perceived stress and if possible gave saliva samples to investigate oxytocin levels. The study was a randomized controlled monocentre study on patients treated in a palliative care ward. Participants had to be conscious and alert enough to complete data collection. Overall, 55 patients were included and randomized to the intervention or control group. RESULTS: Parameters in the control group did not change significantly. In the intervention group, seriousness, bad mood, and stress were reduced. Cheerfulness increased significantly after the intervention. However, the methodologically complex intervention setting was too exhausting for the majority of patients. CONCLUSION: Patients who were able to participate benefited from the effects of the intervention on multiple levels. For future research simple interventions, biomarkers for well-being and assessments by staff or proxies are needed to include patients with reduced cognitive and physical performance status at the end of their lives.

Cultural Differences in How People Deal with Ridicule and Laughter: Differential Item Functioning between the Taiwanese Chinese and Canadian English Versions of the PhoPhiKat-45.

The PhoPhiKat-45 measures three dispositions toward ridicule and laughter, including gelotophobia (i.e., the fear of being laughed at), gelotophilia (i.e., the joy of being laughed at), and katagelasticism (i.e., the joy of laughing at others). Despite numerous cultural adaptations, there is a paucity of cross-cultural studies investigating measurement invariance of this measure. Undergraduate students from a Canadian university (N = 1467; 71.4% females) and 14 universities in Taiwan (N = 1274; 64.6% females) completed the English and Chinese PhoPhiKat-45 measures, respectively. Item response theory and differential item functioning analyses demonstrated that most items were well-distributed across the latent continuum. Five of 45 items were flagged for DIF, but all values had negligible effect sizes (McFadden's pseudo R2 < 0.13). The Canadian sample was further subdivided into subsamples who identified as European White born in Canada (n = 567) and Chinese born in China, Hong Kong, or Taiwan (n = 180). In the subgroup analyses, no evidence of DIF was found. Findings support the utility of this measure across these languages and samples.

Convergence and Psychometric Properties of Character Strengths Measures: The VIA-IS and the VIA-IS-R.

This study compares the German versions of the original measure of character strengths (VIA-IS) with its latest revision (VIA-IS-R) regarding reliability and convergent, discriminant, and criterion-related validity. A sample of 499 German-speaking adults (79% women, mean age: 33.3 years) provided self-reports of character strengths (VIA-IS, VIA-IS-R) and several criteria: Core virtues, thriving, and moral behaviors. Results suggested that both measures showed satisfactory internal consistency and converged well in a multitrait-multimethod analysis. Further, both measures were comparable regarding their relationships with the criteria. Overall, the results of the current study suggest that both questionnaires are reliable and valid, and that findings based on these instruments can be considered highly comparable.

Character Strengths in Adults and Adolescents: Their Measurement and Association with Well-Being.

Character strengths are assessed in adults and adolescents using different measurements. However, a comparison of character strengths across age groups requires the equivalence of these measurements. The present study examined the comparability of the two questionnaires most frequently used in research: The VIA Inventory of Strengths (VIA-IS) for adults and the VIA Inventory of Strengths for Youth (VIA-Youth). A sample of N = 170 high-school students in the age of about 18 years and up to two informants (N = 164 mostly parents; N = 156 mostly friends and partners) completed both character strengths questionnaires and several well-being questionnaires. The psychometric characteristics and the correlations with well-being scales were examined once exclusively on the basis of self-rating and once on the basis of combined self- and informant-ratings. Substantial differences between the questionnaires were found in each of the criteria examined (e.g., identification of signature strengths, or largest associations with well-being). The results indicate that VIA-IS and VIA-Youth measure character strengths differently, so that a comparison across age groups may lead to biased conclusions. Therefore, differences in character strengths between adults and adolescents should not be exclusively interpreted in terms of differences on the trait level as these differences may be caused by nonequivalent questionnaires.

On the relationship between valence and arousal in samples across the globe.

Affect is involved in many psychological phenomena, but a descriptive structure, long sought, has been elusive. Valence and arousal are fundamental, and a key question-the focus of the present study-is the relationship between them. Valence is sometimes thought to be independent of arousal, but, in some studies (representing too few societies in the world) arousal was found to vary with valence. One common finding is that arousal is lowest at neutral valence and increases with both positive and negative valence: a symmetric V-shaped relationship. In the study reported here of self-reported affect during a remembered moment (N = 8,590), we tested the valence-arousal relationship in 33 societies with 25 different languages. The two most common hypotheses in the literature-independence and a symmetric V-shaped relationship-were not supported. With data of all samples pooled, arousal increased with positive but not negative valence. Valence accounted for between 5% (Finland) and 43% (China Beijing) of the variance in arousal. Although there is evidence for a structural relationship between the two, there is also a large amount of variability in this relation. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Humor in radiological breast cancer screening: a way of improving patient service?

BACKGROUND: Breast cancer screening is essential in detecting breast tumors, however, the examination is stressful. In this study we analyzed whether humor enhances patient satisfaction. METHODS: In this prospective randomized study 226 patients undergoing routine breast cancer screening at a single center during October 2020 to July 2021 were included. One hundred thirty-two were eligible for the study. Group 1 (66 patients) received an examination with humorous intervention, group 2 (66 patients) had a standard breast examination. In the humor group, the regular business card was replaced by a self-painted, humorous business card, which was handed to the patient at the beginning of the examination. Afterwards, patients were interviewed with a standardized questionnaire. Scores between the two study groups were compared with the Mann-Whitney U test or Fisher's exact test. P-values were adjusted with the Holm's method. Two-sided p-values < 0.05 were considered significant. RESULTS: One hundred thirty-two patients, 131 female and 1 male, (mean age 59 ± 10.6 years) remained in the final study cohort. Patients in the humor group remembered the radiologist's name better (85%/30%, P < .001), appreciated the final discussion with the radiologist more (4.67 ± 0.73-5;[5, 5] vs. 4.24 ± 1.1-5;[4, 5], P = .017), felt the radiologist was more empathetic (4.94 ± 0.24-5;[5, 5] vs.4.59 ± 0.64-5;[4, 5], P < .001), and rated him as a humorous doctor (4.91 ± 0.29-5;[5, 5] vs. 2.26 ± 1.43-1;[1, 4], P < .001). Additionally, patients in the humor group tended to experience less anxiety (p = 0.166) and felt the doctor was more competent (p = 0.094). CONCLUSION: Humor during routine breast examinations may improve patient-radiologist relationship because the radiologist is considered more empathetic and competent, patients recall the radiologist's name more easily, and value the final discussion more. TRIAL REGISTRATION: We have a general approval from our ethics committee because it is a retrospective survey, the patient lists for the doctors were anonymized and it is a qualitative study, since the clinical processes are part of the daily routine examinations and are used independently of the study. The patients have given their consent to this study and survey.

What constitutes a fulfilled life? A mixed methods study on lay perspectives across the lifespan.

Recently, we initiated a new research line on fulfillment in life by developing a conceptual framework and a self-report measure. To enhance conceptual clarity and complement theoretical considerations and empirical findings, we investigated lay conceptions of a fulfilled life in German-speaking participants at different life stages. First, we selected a qualitative approach using an open-ended question asking participants to describe a fulfilled life. Second, for a more comprehensive understanding, quantitative data were collected about the relevance of sources in providing fulfillment and ratings on a fulfilling life in the present and a fulfilled life in retrospect. Qualitative content analysis was used to assess the responses to the open-ended question. One-fifth of the data was double coded, and intercoder reliability was high (Kappa = 0.89). Responses comprised a variety of descriptions, and we grouped them into seven themes, three of which overlapped with the prior conceptualization, namely the core elements of (a) general description, (b) cognitive appraisals, and (c) affective appraisals. Cognitive evaluations related to intrapersonal aspects, particularly having lived life fully, attained personally significant goals, and developed oneself, as well as interpersonal, generative aspects, such as having made a contribution and been able to leave something of value. These categories are mostly in line with what the Fulfilled Life Scale (FLS) measures. Further themes referred to correlates-including (d) sources-and antecedents, including (e) resources, (f) personal characteristics, and (g) quality of life, all considered worthy to be the subject of empirical investigation but which were not included in the conceptual model. Qualitative and quantitative results suggest that individuals derive fulfillment from different sources. Fulfillment from a profession and having a life task was strongly associated with longer-term fulfillment. Only a few age and sex differences were found. The overarching framework developed from the qualitative results can stimulate further investigation. Our findings underscore that a fulfilled life as a distinct construct should be measured directly rather than via a proxy. Insights into the constituents, sources, and antecedents of a fulfilled life can inform practice to promote a life well lived.

Fear of being laughed at in Italian healthcare workers: Testing associations with humor styles and coping humor.

Humor is a strategy that healthcare workers can use to help patients cope with stress and manage complex situations. However, people differ in how they deal with laughter. Our aim was to investigate gelotophobia (fear of being laughed at) among healthcare professionals and its relationships with humor styles and inclinations to use humor for coping. A sample of 550 Italian healthcare-workers was assigned to three groups: Professional Hospital Clown Group (PHCG, people who trained as professional clown in health-care setting), Humor Training Group (HTG, people who attended health-care relevant training courses related to humor), or Control Group (CG, people who attended healthcare or professional training courses not related to humor), and provided self-reports in the GELOPH < 15 > , the Coping Humor Scale, and the Humor Style Questionnaire. Participants from humor-related interventions, in particular PHCG, were lower in gelotophobia and used humor as a coping strategy. Gelotophobia correlated negatively with coping humor, and affiliative and self-enhancing humor styles. We discuss the findings with regard to the use of humor and laughter in healthcare settings.

Character strengths and fluid intelligence.

OBJECTIVE: Research on the associations between cognitive and noncognitive personality traits has widely neglected character strengths, that means positively and morally valued personality traits that constitute good character. METHOD: The present study aimed to bridge this gap by studying the associations between character strengths and fluid intelligence using different operationalizations of character strengths (including self- and informant-reports) and fluid intelligence in children, adolescents, and adults. RESULTS: The results, based on four samples (N = 193/290/330/324), suggested that morally valued personality traits are independent of fluid intelligence, with the exception of love of learning, which showed small but robust positive relationships with fluid intelligence across all samples. CONCLUSIONS: Nonetheless, we argue for further research on the associations with other cognitive abilities and interactions between character strengths and intelligence when examining their relationships with external criteria.

Migraine and Happiness.

Objective: To investigate the association between happiness and migraine. Background: Contemporary operationalizations of happiness include the prevailing positive over negative affect and the satisfaction with life. Generally, extreme events and circumstances influence happiness only temporarily. However, how does periodic cycling between being relatively healthy and relatively disabled-as in migraineurs-affect happiness? Migraine is a primary headache disorder, in which headache attacks intermittently interfere with normal living and cause a significant personal, societal, and potentially irreversible disease burden. Methods: In this cross-sectional observational study, migraineurs completed the satisfaction with life scale (SWLS), the Patient Health Questionnaire, and the Generalized Anxiety Disorder scale and reported their headache frequency as well as recent changes in that frequency. Furthermore, participants answered a free text question on how to remain happy despite migraine attacks. We built a regression model with the SWLS score as the dependent variable. Results: Seventy participants completed the questionnaire. The regression model revealed that happiness increases with headache days, and subsequent analysis showed a U-shaped relationship between headache frequency and happiness. The participants' advice on remaining happy focused on upvaluing the pain-free time or relieving the attacks themselves. The latter was increasingly common with longer disease durations. Conclusions: Both high and low headache frequencies facilitate adaptation to the disorder, while intermediate frequencies resulted in lower life satisfaction. The nonlinear relationship between happiness and headache days may be due to "hedonic habituation" and implies that headache calendars do not necessarily correctly reflect patients' difficulty to feel well despite the disorder. Many patients advised other migraineurs to increase happiness by enjoying pain-free time. However, with increasing disease duration, patients' recommendations focused on coping with attacks.

Do beliefs in the malleability of well-being affect the efficacy of positive psychology interventions? Results of a randomized placebo-controlled trial.

The present study examines the role of beliefs about the malleability of well-being in a randomized, placebo-controlled, online positive psychology intervention targeting 267 German-speaking adults (83% women, mean age = 43.16 years). The participants of the experimental group ("three good things" intervention) and placebo control group ("early memories") reported their levels of happiness before and immediately after the 1-week intervention, as well as 2, 4, and 12 weeks after the intervention. Furthermore, the researchers recorded how participants completed the exercises and to what extent they liked the exercises. This study also assesses the participants' beliefs surrounding two different aspects of malleability (well-being is modifiable in general, and one knows how to change their well-being). Although both aspects of malleability were strongly intercorrelated, beliefs about how to change one's well-being seemed particularly relevant in the context of positive psychology interventions: Those who reported a stronger belief about how to change their well-being liked the intervention better and more often completed the activity as instructed. Further, they reported greater increases in well-being as compared with the control group. We conclude that beliefs about the malleability of well-being might represent an important moderating variable in the effectiveness of positive psychology interventions.

The State-Trait Cheerfulness Inventory State Version-Short Form (STCI-S18): An Examination of Language Use and Psychometric Properties.

The State-Trait Cheerfulness Inventory-State Version (STCI-S) measures three states of cheerfulness, seriousness, and bad mood as the temperamental basis of humor. The present study investigates (1) the development and psychometric validation of a newly developed short version and (2) test-criterion validity with state measures and language use. Study 1 (N = 933) confirmed the three-dimensional structure, and both the short and standard versions demonstrated strong psychometric properties. Study 2 (N = 617) replicated these findings in a separate sample. Study 3 (N = 750) demonstrated expected intercorrelations with self-report state measures (i.e., inspiration, self-esteem, depression, anxiety). Participants were randomized to expressive writing conditions (i.e., writing about a retrospective cheerful, serious, or bad mood scenario). Unacquainted judges' and participants' ratings of three states in their respective scenarios converged (.44 < r < .62). Retrospective states cheerfulness, seriousness, and bad mood were associated with linguistic categories (e.g., emotional tone, clout, achievement, insight) identified in the Linguistic Inquiry and Word Count (LIWC) software. The impact of personality states on word usage may only be evident in specific contexts and situations. Presence of distinctive language use in these writing samples further demonstrated test-criterion validity and practicality of the STCI-S18.

Exploring the stability of HEXACO-60 structure and the association of gender, age, and social position with personality traits across 18 countries.

OBJECTIVES: The present paper tests the cross-national stability of the HEXACO-60 structure across 18 countries from four continents. Gender and age differences across countries will be examined. Finally, this is the first study to explicitly analyze the relationships between the HEXACO and social position. METHOD: Ten thousand two hundred and ninety eight subjects (5,410 women and 4,888 men) from 18 countries and 13 languages were analyzed. Confirmatory factor analysis techniques were used to test configural, metric and scalar invariance models. Congruence coefficients with the original structure of the HEXACO-60 were computed for every culture. Effect sizes of gender, age, and social position factors across countries were also computed. RESULTS: HEXACO-60 demonstrates configural and metric invariance, but not scalar invariance. Congruence coefficients show a great equivalence in almost all countries and factors. Only Emotionality presents a large gender difference across countries. No relevant effect of age is observed. A profile of high scores on Honesty-Humility, Extraversion, Conscientiousness, and Openness to Experience, and low scores on Emotionality increases the likelihood of achieving a higher social position, although the effect sizes are small. CONCLUSIONS: HEXACO-60 is a useful instrument to conduct personality trait research and practice around the world. Implications of gender, social position, and country differences are discussed.

Character Strengths in the Life Domains of Work, Education, Leisure, and Relationships and Their Associations With Flourishing.

A growing body of research demonstrates the relevance of character strengths for flourishing in general, but also for important outcomes across different life domains (e.g., work performance and relationship satisfaction). Studies have also shown that there are differences in the extent to which character strengths are applied, that is, perceived as relevant and shown in behavior in a given context, between work and private life, but they have not considered other life domains. This study aims to close this gap by examining the life domains of work, education, leisure, close personal relationships, and romantic relationships. The present study investigates whether (a) strengths-related behavior across different life domains explains additional variance in flourishing beyond the trait level of each respective character strength and studies (b) differences in the relevance of character strengths and strengths-related behavior across different life domains, and examines (c) their relationships with flourishing. A sample of 203 German-speaking adults (78.8% females; mean age = 29.4 years) completed self-reports assessing flourishing and character strengths. They also indicated which of the five life domains were personally relevant to them (i.e., on average 4.23 life domains) and reported the character strengths' perceived relevance and the frequency of displaying strengths-related behavior for each of these life domains separately. The results demonstrate that (a) strengths-related behavior averaged across all relevant life domains explained unique variance in flourishing above the trait-level of character strengths in some cases (e.g., creativity, kindness, and fairness), (b) different life domains were characterized by specific profiles of character strength-regarding both their relevance and strength-related behavior. Moreover, (c) character strengths and strengths-related behavior in different life domains both showed substantial correlations with flourishing. In some cases, these associations were domain-specific (e.g., displaying love of learning in the context of education was related to higher levels of flourishing). In conclusion, we suggest that examining strengths-related behavior across different life domains represents a worthwhile addition to research on character strengths.

Measuring What Counts in Life: The Development and Initial Validation of the Fulfilled Life Scale (FLS).

In a recent work, we introduced a theoretical model for fulfillment in life that covers cognitive and affective components and distinguishes different time frames. The present study evaluates this model and describes the construction of the Fulfilled Life Scale (FLS) to assess fulfillment regarding the whole lived life retrospectively. We investigated the scale in two samples (Sample 1: N = 282 adults aged 50-93 years; Sample 2: N = 406 adults aged 40-85 years). The model of the cognitive component combines three sources of fulfillment (self, life, impact/legacy) with three criteria (wholeness, fit, value), yielding nine facets. Employing hierarchical factor analysis, we inspected all solutions between one and nine. We identified three optimal factors, which we labeled unfolded self and life, the worthwhile life, and positive impact and legacy. Next, we selected marker items and replicated the factor structure in Sample 2. The three scales were positively intercorrelated and showed good internal consistency in both samples. For the affective component, exploratory and confirmatory factor analyses established a one-factor structure in both samples, and high internal consistency was obtained. Across a range of related constructs, we demonstrated construct and criterion validity. Notably, cognitive and affective fulfillment incrementally predicted a global rating of a fulfilled life and mental well-being, even after controlling for subjective and eudaimonic well-being. Overall, the study proves that the FLS is necessary to capture people's experience of a fulfilled life, which could not be assessed sufficiently with previous well-being measures. Both cognitive and affective fulfillment were able to predict additional variance in mental well-being. Moreover, the study reveals psychometric support for the FLS and presents the first evidence on its validity. Lastly, applications in research and practice are discussed, especially in the context of living and aging well in the second half of life.

Development and Linguistic Cue Analysis of the State-Trait Cheerfulness Inventory-Short Form.

The present study derived a short form of the State-Trait Cheerfulness Inventory-Trait Version (STCI-T30) using an item response theory framework. Latent trait test-retest correlations and reliability across the latent continuum in the STCI-T30 remained high. Moreover, the STCI-T30 showed external validity with criterion variables (e.g., playfulness) and a short writing task completed by these participants was rated by unacquainted judges to infer the author's cheerfulness, seriousness, and bad-mood. Results suggested significant self-other and inter-judge agreement of cheerfulness, seriousness, and bad-mood and linguistic cues analysis suggested cheerfulness and bad-mood manifested through writing in tone, social processes, and affect.
