Development and evaluation of a predictive algorithm and telehealth intervention to reduce suicidal behavior among university students.

BACKGROUND: Suicidal behaviors are prevalent among college students; however, students remain reluctant to seek support. We developed a predictive algorithm to identify students at risk of suicidal behavior and used telehealth to reduce subsequent risk. METHODS: Data come from several waves of a prospective cohort study (2016-2022) of college students (n = 5454). All first-year students were invited to participate as volunteers. (Response rates range: 16.00-19.93%). A stepped-care approach was implemented: (i) all students received a comprehensive list of services; (ii) those reporting past 12-month suicidal ideation were directed to a safety planning application; (iii) those identified as high risk of suicidal behavior by the algorithm or reporting 12-month suicide attempt were contacted via telephone within 24-h of survey completion. Intervention focused on support/safety-planning, and referral to services for this high-risk group. RESULTS: 5454 students ranging in age from 17-36 (s.d. = 5.346) participated; 65% female. The algorithm identified 77% of students reporting subsequent suicidal behavior in the top 15% of predicted probabilities (Sensitivity = 26.26 [95% CI 17.93-36.07]; Specificity = 97.46 [95% CI 96.21-98.38], PPV = 53.06 [95% CI 40.16-65.56]; AUC range: 0.895 [95% CIs 0.872-0.917] to 0.966 [95% CIs 0.939-0.994]). High-risk students in the Intervention Cohort showed a 41.7% reduction in probability of suicidal behavior at 12-month follow-up compared to high-risk students in the Control Cohort. CONCLUSIONS: Predictive risk algorithms embedded into universal screening, coupled with telehealth intervention, offer significant potential as a suicide prevention approach for students.

The role of self-compassion in loneliness during the COVID-19 pandemic: a group-based trajectory modelling approach.

Research has suggested an increase in loneliness during the COVID-19 pandemic, but much of this work has been cross-sectional, making causal inferences difficult. In the present research, we employed a longitudinal design to identify loneliness trajectories within a period of twelve months during the COVID-19 pandemic in Belgium (N = 2106). We were particularly interested in the potential protective role of self-compassion in these temporal dynamics. Using a group-based trajectory modelling approach, we identified trajectory groups of individuals following low (11.0%), moderate-low (22.4%), moderate (25.7%), moderate-high (31.3%), and high (9.6%) levels of loneliness. Findings indicated that younger people, women, and individuals with poor quality relationships, high levels of health anxiety, and stress related to COVID-19, all had a higher probability of belonging to the highest loneliness trajectory groups. Importantly, we also found that people high in two of the three facets of self-compassion (self-kindness and common humanity) had a lower probability of belonging to the highest loneliness trajectory groups. Ultimately, we demonstrated that trajectory groups reflecting higher levels of loneliness were associated with lower life satisfaction and greater depressive symptoms. We discuss the possibility that increasing self-compassion may be used to promote better mental health in similarly challenging situations.

Construct Validity and Measurement Invariance of the Difficulties in Emotion Regulation Scale - Short Form (DERS-SF): Further Evidence From Community and Student Samples.

The current study aimed to evaluate the psychometric properties of the Difficulties in Emotion Regulation Scale-Short Form (DERS-SF) in Iran, including testing its measurement invariance across sexes, as well as community and student populations. Two samples were recruited: a community sample of 583 participants (58.7% female; Mage = 33.55) and a university student sample of 409 participants (67.2% female; Mage = 24.48). Besides the DERS-SF, participants completed a battery of instruments online, measuring mentalizing capacity and borderline personality features. Confirmatory factor analyses supported the tenability of the five-factor model, excluding the awareness subscale. Except for the awareness subscale, acceptable to excellent internal consistencies were found for the DERS-SF and its subscales. The awareness-excluded DERS-SF was significantly and strongly associated with relevant constructs (|rs| = .49 to .59). This study also found evidence for configural, metric, and scalar invariance of the DERS-SF across sexes and community and student populations. Our findings extended the evidence for the validity and reliability of the DERS-SF and its awareness-excluded version by administering it in Iranian samples and supporting its cross-cultural applicability.

Assessing Emotion Regulation across Asian and Western Cultures: Psychometric Properties of Three Common Scales across Singaporean and Australian Samples.

Given the differences in emotion regulation across cultures, it is paramount to ensure that measures of emotion regulation measure the same construct and that conceptualizations of emotion regulation are valid across cultures. Therefore, the present study assessed the measurement invariance (alongside other psychometric properties) of three popular emotion regulation questionnaires, the Emotion Regulation Questionnaire (ERQ), Difficulties in Emotion Regulation Scale (DERS), and the Perth Emotion Regulation Competency Inventory (PERCI), across 434 Singaporeans and 489 Australians. Our study showed that all three questionnaires were measurement invariant, had excellent internal consistency, and relatively good concurrent validity with psychopathology and alexithymia across our Singaporean and Australian sample, justifying their use in comparing Asian and Western cultures. Our findings suggest that measures of emotion regulation have utility across both individualistic and collectivistic cultures. Our findings supports the use of these measures in cross-cultural research and provides support for the utility for personality assessments across cultures.

Cross-cultural adaptation and clinical application of the Perth Empathy Scale.

OBJECTIVE: Alterations of empathy have been observed in patients with various mental disorders. The Perth Empathy Scale (PES) was recently developed to measure a multidimensional construct of empathy across positive and negative emotions. However, its psychometric properties and clinical applications have not been examined in the Chinese context. METHODS: The Chinese version of the PES was developed and administered to a large Chinese sample (n = 1090). Factor structure, internal consistency, test-retest reliability, and convergent, discriminant, as well as concurrent validity were examined. Moreover, 50 patients with major depressive disorder (MDD) and 50 healthy controls were recruited to explore the clinical utility of the PES. RESULTS: Confirmatory factor analyses supported a theoretically congruent three-factor structure of empathy, namely Cognitive Empathy, Negative Affective Empathy and Positive Affective Empathy. The PES showed good to excellent internal consistency reliability, good convergent and discriminant validity, acceptable concurrent validity, and moderate to high test-retest reliability. Patients with MDD had significantly lower PES scores compared to healthy controls. Linear discriminant function comprised of the three factors correctly differentiated 71% of participants, which further verified the clinical utility of the PES. CONCLUSIONS: Our findings indicated that the Chinese version of the PES is a reliable and valid instrument to measure cognitive and affective empathy across negative and positive emotions, and could therefore be used in both research and clinical practice.

Alexithymia as a risk factor for poor emotional outcomes in adults with acquired brain injury.

Emotional disorders are pervasive in the acquired brain injury (ABI) population, adversely affecting quality of life and rehabilitation. This study aimed to explore the unique associative effects of alexithymia as measured by the Perth Alexithymia Questionnaire (PAQ; i.e., difficulty identifying positive/negative feelings, difficulty describing positive/negative feelings, and externally orientated thinking), on emotional outcomes as measured by the Depression Anxiety Stress Scale-21 (DASS-21) and Mayo-Portland Adaptability Inventory (MPAI-4) Adjustment index, in 83 adults with ABI. The addition of alexithymia to hierarchical multiple regression models (controlling for demographic, injury-related, and functional outcome variables) yielded statistically significant changes in R2 for all emotional outcome measures (i.e., Depression, Anxiety, Stress, and Adjustment). Difficulty identifying negative feelings was found to be a significant unique predictor of Depression (ß = .43 p = <.001), Anxiety (ß = .40, p <.001), Stress (ß = .49, p <.001), and Adjustment (ß = .26, p = .001). Externally oriented thinking was found to be a significant unique predictor of Adjustment (ß = -.15, p = .033). These findings strengthen the argument that alexithymia, especially difficulties identifying negative feelings, may be an important risk factor for psychological distress in ABI and should be considered during early rehabilitation.

Parental Assistance with Emotion Regulation Moderates Link Between COVID-19 Stress and Child Mental Health.

OBJECTIVE: The COVID-19 pandemic has severely impacted children's mental health. All children have not been affected equally, however, and whether parental emotion socialization might buffer or exacerbate the impact of COVID-19 on children's mental health remains an important question. METHOD: During the first peak of the COVID-19 pandemic in the U.S. N = 200 parents of children ages 0-17 (52.5% female) completed questionnaires related to parental assistance with children's emotion regulation, symptomatology, and exposure to COVID-19-related stress. Parents were 74% Non-Hispanic/Latino/a White, 13% Asian, 4.5% Hispanic/Latino/a, 4% Black/African American, 2.5% Native American, and 1.5% bi/multiracial; 0.5% of participants preferred not to state their race/ethnicity. In a series of linear regression analyses, we examined whether parental assistance with children's execution of emotion regulation strategies - across a variety of prototypically-adaptive and -maladaptive strategies - moderates the association between children's exposure to COVID-19-related stress and symptomatology. RESULTS: Results suggest that parental assistance with the execution of prototypically-adaptive strategies (i.e., acceptance, problem solving, behavioral disengagement) and prototypically-maladaptive strategies (i.e., suppression, rumination) may buffer or exacerbate, respectively, the impact of COVID-19-related stress on youth mental health. CONCLUSIONS: Though interpretation of findings is constrained by limitations inherent in collecting data during a pandemic, results highlight the importance of supporting parents - who play a critical role of supporting children - during public health emergencies that affect family life. Interventions designed to improve child wellbeing during the ongoing pandemic may benefit from training parents to assist their children with specific emotion regulation strategies.

Alexithymia in nonviolent offenders.

BACKGROUND: Alexithymia is a trait involving difficulties processing emotions. Existing data suggest it is associated with violent offending. In violent offender programmes, therefore, violent offenders are screened for alexithymia and it is attended to if necessary. No studies have, however, examined alexithymia levels in nonviolent offenders and it is, therefore, unknown whether it is also a criminogenic factor in this population. AIMS: To investigate alexithymia levels among incarcerated nonviolent offenders and compare them with a community comparison group. METHOD: The 20-item Toronto Alexithymia Scale was used to compare the alexithymia levels of 67 incarcerated nonviolent offenders with a group of 139 people from the general public living in the community. RESULTS: Alexithymia levels did not differ between the groups. CONCLUSION: It appears that alexithymia is not a criminogenic factor for nonviolent offenders and screening of such offenders appears unnecessary.

Assessing alexithymia in forensic settings: Psychometric properties of the 20-item Toronto Alexithymia Scale among incarcerated adult offenders.

BACKGROUND: Alexithymia is a trait involving difficulty identifying feelings (DIF), difficulty describing feelings (DDF) and externally orientated thinking (EOT). It is a risk factor for criminal behaviour. It is commonly assessed with the Toronto Alexithymia Scale (TAS-20), but the psychometrics of the TAS-20 have not been tested across the range of offender populations, and it has been suggested it might be unsuitable in incarcerated offenders. AIM: To establish the psychometrics of the TAS-20 among incarcerated offenders. METHODS: Factorial validity was examined using confirmatory factor analyses, and the invariance of this factor structure was tested against a published community sample. Reliability coefficients were calculated. RESULTS: One hundred and forty six incarcerated offenders were recruited. The factor structure of the TAS-20 was invariant across the samples. The intended factor structure composed of DIF, DDF and EOT factors performed well overall (with a reverse-scored method factor added), but six EOT items had low factor loadings. The total scale score and DIF and DDF subscales had acceptable reliability, but EOT did not. CONCLUSIONS: Our results suggest that the TAS-20 functions similarly in offender and community samples. Its total scale score, and DIF and DDF subscale scores can be used confidently, but the assessment of externally oriented thinking may not be adequate with this scale alone. In sum, the TAS-20 can facilitate robust assessment of alexithymia in closed criminal justice settings as well as in the wider community.

What is alexithymia? Using factor analysis to establish its latent structure and relationship with fantasizing and emotional reactivity.

OBJECTIVE: There is ongoing uncertainty about the structure and definition of alexithymia. Conceptually, alexithymia has traditionally been defined as a multidimensional trait with four components: difficulty identifying feelings, difficulty describing feelings, externally orientated thinking, and difficulty fantasizing. However, some authors suggest that difficulty fantasizing might not be a component, and others suggest low emotional reactivity is a fifth component. In this study, we sought to clarify this issue using factor analysis. METHOD: In a sample of adults (N = 508), we administered a comprehensive battery of psychometric measures and analyzed their latent structure using exploratory factor analysis. RESULTS: Subscales assessing difficulty identifying feelings, difficulty describing feelings, and externally orientated thinking all loaded well together on the alexithymia factor. However, none of the subscales assessing aspects of difficulty fantasizing (i.e., daydreaming frequency, vividness, content, or use of daydreams to regulate emotions) loaded on the alexithymia factor. Similarly, no emotional reactivity subscales loaded on the alexithymia factor, and alexithymia was associated with higher (not lower) levels of emotional reactivity for negative emotions. CONCLUSIONS: Difficulty fantasizing and low emotional reactivity are not components of the latent alexithymia construct. The traditional four-component definition of alexithymia likely warrants refinement to a more parsimonious three-component solution.

The Emotion Regulation Questionnaire: Psychometric Properties in General Community Samples.

The Emotion Regulation Questionnaire (ERQ) is a 10-item self-report measure of 2 emotion regulation strategies, cognitive reappraisal and expressive suppression. It is a widely used measure of emotion regulation, but its factor structure has rarely been examined outside of university student samples, and some authors have recently questioned its factorial validity in general community samples. In this study, we examine the psychometric properties of the ERQ (original English version) in 3 Australian general community samples (N = 300, 400, 348). Confirmatory factor analyses in each sample demonstrated that the traditional 2-factor model (comprised of cognitive reappraisal and expressive suppression factors) was replicable and an excellent fit to the data. In all samples, ERQ cognitive reappraisal (α = .89-.90) and expressive suppression (α = .76-.80) scores had acceptable to excellent levels of internal consistency reliability. As expected, cognitive reappraisal scores were significantly negatively correlated with psychological distress and alexithymia, whereas expressive suppression scores were significantly positively correlated with psychological distress and alexithymia. We conclude that, similar to previous findings in student samples, the ERQ has strong psychometric properties in general community samples and can therefore be used confidently regardless of participants' student status.

Alexithymia or general psychological distress? Discriminant validity of the Toronto Alexithymia Scale and the Perth Alexithymia Questionnaire.

BACKGROUND: Alexithymia is an important transdiagnostic risk factor for emotion-based psychopathologies. However, it remains unclear whether alexithymia questionnaires actually measure alexithymia, or whether they measure emotional distress. Our aim here was to address this discriminant validity concern via exploratory factor analysis (EFA) of the 20-item Toronto Alexithymia Scale (TAS-20) and the Perth Alexithymia Questionnaire (PAQ). METHOD: United States general community adults (N = 508) completed the TAS-20, PAQ, and the Depression Anxiety Stress Scales-21 (DASS-21). EFA was used to examine the latent dimensions underlying these measures' scores. RESULTS: Our EFA extracted two higher-order factors, an "alexithymia" factor and a "general distress" factor (i.e., depression, anxiety, stress). All PAQ scores loaded cleanly on the alexithymia factor, with no cross-loadings on the distress factor. However, for the TAS-20, Difficulty Identifying Feelings (DIF) facet scores cross-loaded highly on the distress factor. LIMITATIONS: Our sample consisted of general community adults; future work in clinical settings will be useful. CONCLUSIONS: Our data indicate that the PAQ has good discriminant validity. However, the TAS-20 appears to have significant discriminant validity problems, in that much of the variance in its DIF facet reflects people's current levels of distress, rather than alexithymia. The TAS-20, which has traditionally been the most widely used alexithymia questionnaire, may therefore not be the optimal alexithymia tool. Our findings add to the body of evidence supporting the validity and utility of the PAQ and suggest that, moving forward, it is a superior option to the TAS-20 for alexithymia assessments.

The Climate Change Worry Scale (CCWS) and Its Links with Demographics and Mental Health Outcomes in a Polish Sample.

Developing valid and reliable measures of psychological responses to climate change is of high importance, as this facilitates our understanding of people's psychological responses, including their pro-environmental behavior. Recently, the Climate Change Worry Scale (CCWS) was introduced. This study aimed to develop the first Polish version of the CCWS and explore its psychometric properties. Our sample comprised 420 Polish adults aged 18-70, with a mean age of 26.20 (standard deviation = 10.61) years. The CCWS's factor structure was assessed with confirmatory factor analysis. McDonald's omega and Cronbach's alpha coefficients were computed to assess internal consistency reliability. Pearson correlations between climate change worry (CCW) and experience of climate change (i.e., an individual's level of perception of being affected by climate change), pro-environmental behavior, ill-being (i.e., anxiety and depression symptoms), and well-being were calculated. Our results support the strong factorial validity of the CCWS, conforming to its intended one-factor solution, with excellent internal consistency reliability for the total scale score (i.e., McDonald's omega and Cronbach's alpha values of 0.93). We noted large positive correlations between CCW and experiences of climate change, as well as pro-environmental behavior, and medium positive correlations with psychopathology symptoms. CCW scores were not associated with well-being. As the CCWS represents a measure of a specific manifestation of worry, we also examined its discriminant validity against more general psychological distress markers, and it evidenced strong validity in this regard. Overall, the Polish version of the CCWS appears to have strong psychometric properties, and will therefore be a useful tool to use in research on psychological responses to climate change.

Alexithymia profiles and depression, anxiety, and stress.

BACKGROUND: Alexithymia is a multidimensional trait comprised of difficulties identifying feelings, difficulties describing feelings, and externally orientated thinking. It is regarded as an important risk factor for emotional disorders, but there are presently limited data on each specific facet of alexithymia, or the extent to which deficits in processing negative emotions, positive emotions, or both, are important. In this study, we address these gaps by using the Perth Alexithymia Questionnaire (PAQ) to comprehensively examine the relationships between alexithymia and depression, anxiety, and stress symptoms. METHODS: University students (N = 1250) completed the PAQ and the Depression Anxiety Stress Scales-21. Pearson correlations, hierarchical regressions, and latent profile analysis were conducted. RESULTS: All facets of alexithymia, across both valence domains, were significantly correlated with depression, anxiety, and stress symptoms (r = 0.27-0.40). Regression analyses indicated that the alexithymia facets, together, could account for a significant 14.6 %-16.4 % of the variance in depression, anxiety, and stress. Difficulties identifying negative feelings and difficulties identifying positive feelings were the strongest unique predictors across all symptom categories. Our latent profile analysis extracted eight profiles, comprising different combinations of alexithymia facets and psychopathology symptoms, collectively highlighting the transdiagnostic relevance of alexithymia facets. LIMITATIONS: Our study involved a student sample, and further work in clinical samples will be beneficial. CONCLUSIONS: Our data indicate that all facets of alexithymia, across both valence domains, are relevant for understanding depression, anxiety, and stress. These findings demonstrate the value of facet-level and valence-specific alexithymia assessments, informing more comprehensive understanding and more targeted treatments of emotional disorder symptoms.

The Emotion Beliefs Questionnaire: Psychometric properties, norms, and links to affective outcomes.

BACKGROUND: The Emotion Beliefs Questionnaire was recently developed to measure beliefs about the controllability and usefulness of negative and positive emotions. These are beliefs that have been theorised to be influential for emotion regulation and psychological outcomes. However, to date there are few studies utilising large, representative samples to examine the EBQ's psychometric properties and affective correlates. Our aim was to fill this gap by examining the EBQ's psychometric properties and exploring associations between emotion beliefs, emotion regulation, and affective disorder symptoms. METHODS: A sample of 1175 adults recruited from the general population in the United States completed measures of emotion beliefs, emotion regulation, and affective disorder symptoms. RESULTS: Confirmatory factor analyses supported the EBQ's intended subscale structure, where controllability and usefulness beliefs were separated by valence. This structure was invariant across gender, age, and education categories. The EBQ correlated in expected ways with other measures, demonstrating good validity, and had good to excellent levels of internal consistency reliability. LIMITATIONS: This study used a non-clinical sample that was predominantly White. Future work should utilise clinical and cross-cultural samples to maximise generalisability of findings. CONCLUSIONS: Our findings indicate that the EBQ is a psychometrically sound tool for measuring the multidimensional emotion belief construct. The EBQ may have clinical utility in the conceptualisation, assessment, and treatment of maladaptive emotion beliefs. Furthermore, our results highlight the importance of considering the potential influence of maladaptive emotion beliefs in emotion dysregulation and affective disorder symptoms.

Attentional engagement with and disengagement from appearance ideals: Differential associations with body dissatisfaction frequency and duration?

Recent work has served to dissociate two dimensions of trait body dissatisfaction: body dissatisfaction frequency and body dissatisfaction duration. The present study sought to evaluate whether body dissatisfaction frequency and body dissatisfaction duration are each associated with distinct patterns of appearance-related cognitive processing. It was hypothesized that speeded attentional engagement with idealized bodies is associated with higher frequency of body dissatisfaction episodes, while slowed attentional disengagement from such information may instead be associated with higher duration of body dissatisfaction episodes. Participants (238 women, 149 men) completed an attentional task capable of independently assessing attentional engagement with, and attentional disengagement from, idealized bodies. Participants also completed both trait and in vivo (i.e., ecological momentary assessment) measures of body dissatisfaction frequency and duration. Results showed that neither engagement nor disengagement bias index scores predicted variance in either body dissatisfaction frequency measures or body dissatisfaction duration measures. Findings suggest that either biased attentional engagement with, and disengagement from, idealized bodies do not associate with the frequency and duration of body dissatisfaction episodes, or there are other key moderating factors involved in the expression of body dissatisfaction-linked attentional bias.

Chinese version of the Perth Alexithymia Questionnaire: psychometric properties and clinical applications.

Background: The alexithymia trait is of high clinical interest. The Perth Alexithymia Questionnaire (PAQ) was recently developed to enable detailed facet-level and valence-specific assessments of alexithymia. Aims: In this paper, we introduce the first Chinese version of the PAQ and examine its psychometric properties and clinical applications. Methods: In Study 1, the PAQ was administered to 990 Chinese participants. We examined its factor structure, internal consistency, test-retest reliability, as well as convergent, concurrent and discriminant validity. In Study 2, four groups, including a major depressive disorder (MDD) group (n=50), a matched healthy control group for MDD (n=50), a subclinical depression group (n=50) and a matched healthy control group for subclinical depression (n=50), were recruited. Group comparisons were conducted to assess the clinical relevance of the PAQ. Results: In Study 1, the intended five-factor structure of the PAQ was found to fit the data well. The PAQ showed good internal consistency and test-retest reliability, as well as good convergent, concurrent and discriminant validity. In Study 2, the PAQ was able to successfully distinguish the MDD group and the subclinical depression group from their matched healthy controls. Conclusions: The Chinese version of the PAQ is a valid and reliable instrument for comprehensively assessing alexithymia in the general population and adults with clinical/subclinical depression.

The Perth Empathy Scale: Psychometric Properties of the Polish Version and Its Mental Health Correlates.

The Perth Empathy Scale (PES) is a 20-item self-report questionnaire that assesses people's ability to recognize emotions in others (i.e., cognitive empathy) and vicariously experience other's emotions (i.e., affective empathy), across positive and negative emotions. Originally developed in English, the aim of our study was to introduce the first Polish version of the PES and test its psychometric performance. Our sample was 318 people (184 females, 134 males) with ages ranging from 18 to 77. The factor structure was verified with confirmatory factor analysis. Reliability was tested in terms of internal consistency and test-retest reliability. To explore convergent, divergent, and discriminant validity, we examined relationships between the PES and measures of depression, anxiety, and emotional intelligence. It was shown that the scale was characterized by the intended four-factor solution, thus supporting factorial validity. The internal consistency reliability was also good and test-retest reliability was moderate. The convergent, divergent, and discriminant validity were strong. The clinical importance of assessing affective empathy across both positive and negative emotions was supported. Overall, our results therefore suggest that the Polish version of the PES has strong psychometric performance and clinical relevance as a measure of the multidimensional empathy construct.

Intolerance of uncertainty and anxiety: The role of beliefs about emotions.

BACKGROUND: Intolerance of uncertainty (IU) is a dimensional trait fundamental to most psychopathologies, and anxiety disorders in particular, making it an important transdiagnostic construct for researchers and clinicians. Current psychological therapies focus on changing underlying cognitive assumptions related to uncertainty. However, we posit that IU conveys beliefs about emotions too. In line with established findings on beliefs about emotions in general, we tested the hypothesis that the relationship between IU and anxiety is mediated by beliefs about the controllability and/or usefulness of emotions. METHODS: Participants (N = 2260) were administered the Emotions Beliefs Questionnaire (EBQ); the General Anxiety Disorder 7-item (GAD-7), and the Intolerance of Uncertainty Scale (IUS - 12). A confirmatory factor analysis (CFA) on the EBQ was conducted followed by Pearson correlation coefficients among the central measures, and a parallel mediation analysis to address the central research question. RESULTS: Our CFA supported the intended factor structure of the EBQ. The results of our mediation analysis supported the prediction that the association between IU and anxiety is partially mediated by general beliefs about emotions. LIMITATIONS: Although our sample size was large, the age range was limited so future research could expand the age range to maximise generalizability. This is a cross-sectional study so causal inferences are restricted. CONCLUSION: Given the present findings, current interventions for IU and their focus on beliefs about uncertainty, might benefit from incorporating strategies to improve beliefs about emotions, and thus improve therapeutic effectiveness.

The Psychometric Assessment of Empathy: Development and Validation of the Perth Empathy Scale.

Empathy, the ability to infer and share others' affective states, plays a vital role in social interactions. However, no existing scale comprehensively assesses empathy's cognitive and affective components across positive and negative emotional valence domains. This article explores the latent structure of the empathy construct and attempts to remedy past measurement limitations by developing and validating a new 20-item self-report measure, the Perth Empathy Scale (PES). In Study 1 (N = 316), factor analyses revealed a coherent empathy construct comprised of cognitive and valence-specific affective components. Study 2 (N = 331) replicated this factor structure, showed measurement invariance between males and females, and highlighted the importance of assessing negative and positive emotions in empathy. The PES showed convergent and discriminant validity from comparisons with alexithymia and other empathy measures. Overall, this article empirically establishes a conceptually clear structure of the multidimensional empathy construct, which the PES reliably and validly measures.
