Psychometric properties of the KCCQ-12 in an european cohort of patients with heart failure

Abstract Background Despite medical advances, patients with heart failure continue to suffer from poor quality of life due to worsening symptoms and functional limitations. Therefore, it is important to understand the multidimensional facets of quality of life in these patients. The Kansas City Cardiomyopathy Questionnaire is a commonly used quality of life assessment tool worldwide. However, However, there is still a lack of knowledge about its psychometric properties. Purpose The aim of this study was to investigate the psychometric properties of the KCCQ-12 and its measurement invariance in a cohort of European patients with heart failure. Methods Participants (n=510, median age=72, IQR=18, 58% males) completed the KCCQ-12 alongside measures of clinical psychosocial severity. A confirmatory factor analysis was used to establish factorial validity; internal consistency was determined using the Omega coefficient and the model-based internal consistency coefficient. Zero-order correlations between the KCCQ-12 scores and clinical and psychosocial measures were performed to test convergent validity. Multigroup confirmatory factor analysis was conducted to test measurement invariance across patients with preserved vs reduced ejection fraction. Results Confirmatory factor analysis confirmed a four-factor solution, with the domains of physical limitations, symptom frequency, quality of life, and social interference. Internal consistency was excellent (Omega coefficients ranging from 0.83 and 0.90, and internal consistency index of 0.94). The KCCQ-12 scores significantly correlated with ejection fraction, New York Heart Association class, quality of life, anxiety, depression, symptom burden, and the KCCQ-23 Overall Summary score, which adequately supported the convergent validity of the KCCQ-12. Measurement invariance was confirmed at the partial scalar and strict level. Conclusions These findings support the validity and reliability of the KCCQ-12, both in patients with reduced and preserved ejection fraction. Hence, this version can be confidently used both in research and clinical practice to measure quality of life of heart failure patients.

Development of a Japanese Version of the Brief Ageing Perceptions Questionnaire and Its Validity and Reliability

Background: Self-perceptions of aging are important predictors of physical and mental health, longevity, and quality of life. The Brief Ageing Perceptions Questionnaire (B-APQ) is the most promising scale of self-perceptions about aging and has been translated into many languages. This study aimed to develop a Japanese version of the B-APQ and examine its validity and reliability. Methods: A web-based survey of 1500 people aged 65 and older was conducted in Japan. Of the participants, 651 were men and 849 were women. The average age was 72.97 years. Results: No significant distributional biases were found for any items of the Japanese version of the B-APQ. A confirmatory factor analysis (CFA) was conducted using the same model as the previous studies. The results of CFA showed that the goodness of fit indices met the acceptability criteria. Two-tailed Pearson correlations showed significant relationships between each factor of the Japanese version of the B-APQ as well as the cognitive and physical functioning, depression, and well-being of older adults. Conclusions: The Japanese version of the B-APQ has high internal consistency and significant factorial and construct-related validity. The Japanese version of the B-APQ is expected to be used to measure the self-perceptions of aging for further study in Japan.

Development and validation of the Environmental Confinement Stressors Scale (ECSS-20).

The COVID-19 pandemic has generated a global crisis with severe consequences for public health. There have been negative impacts on people's quality of life and mental health due to various stressors arising in this context, such as physical, social, economic, and psychological challenges. Noteworthy among these are the indirect effects of health measures, especially social distancing and confinement, which have significantly altered people's daily lives and social activities, producing high levels of anxiety, depression, and stress. This study proposes developing and validating a cross-sectional scale called the "Environmental Stressors Scale (ECSS-20)" to address the need to measure the impact of environmental stressors during confinement. The scale, which has been validated following ethical and methodological guidelines, consists of four dimensions: economic stressors (EE), social activities (SA), habitability (H), and exposure to virtual media (EMV). A pilot study (n = 113) and a main study (n = 314) were applied. The results showed that the instrument has a reliable and valid structure, with satisfactory internal consistency and factorial validity. Likewise, gender invariance tests supported its suitability for its applicability to women and men. Overall, the ECSS-20 is a valuable instrument for assessing the impact of confinement and improving the understanding of people's subjective experiences in this situation. Future research could further develop its applicability in different contexts and populations to better understand its usefulness and psychometric properties.

Validation of the Ukrainian versions of two life purpose scales: Revised sense of purpose in life scale (SOPS-2U) and specific purpose orientations (SPO-U)

This work focused on the translation and evaluation of the psychometric properties of two widely used scales for assessing sense of purpose in life – the Revised Sense of Purpose Scale (SOPS-2) and the Specific Purpose Orientations (SPO) scale – in the Ukrainian language. The SOPS-2 consisted of 14 items measuring three dimensions of purpose: awakening to purpose, awareness of purpose, and altruistic purpose. Meanwhile, the SPO included 12 items assessing three types of purpose: others-growth, self-growth, and career-focused purpose orientations. Renamed as the Revised Sense of Purpose Scale – Ukrainian Version (SOPS-2U) and the Specific Purpose Orientations – Ukrainian Version (SPO-U), these two scales underwent a thorough translation process by two multilingual scholars proficient in both Ukrainian and English languages, employing the committee approach. Then through analyses of two datasets, the factorial validity, construct validity, and reliability of the SOPS-2U and SPO-U were established. These translated scales provide reliable and valid tools for assessing life purpose among Ukrainian-speaking adults.•Recognizing the profound impact of life purpose on adult wellbeing, the availability of a psychometrically robust measurement tool for assessing this construct in the Ukrainian language becomes crucial; thus, we translated and validated two such tools.•The Revised Sense of Purpose Scale – Ukrainian Version (SOPS-2U) is valid for assessing awakening to purpose, awareness of purpose, and altruistic purpose dimensions in Ukrainian adults.•The Specific Purpose Orientations – Ukrainian Version (SPO-U) can be used with Ukrainian adults to further examine the specific types of purpose, such as others-growth, self-growth, and career-focused purpose orientations.

On the nature of influence: identifying and characterizing superdiffusers in seven countries

Abstract An important component of theoretical and applied work on social influence is identifying influential people. Boster et al.’s theoretical framework on superdiffusers provides one method of doing so, but important questions on the nature of influence remain. In particular, because existing studies have primarily sampled U.S. college students, it remains unclear whether (a) the framework adequately characterizes superdiffusers in different populations and (b) our current understanding of superdiffusers applies outside of the United States. To address these questions, we used an online survey to examine factorial validity, metric invariance, and correlates of superdiffuser characteristics in the United States, the United Kingdom, Singapore, South Africa, India, Pakistan, and Australia (total N = 3,476). Results suggest the superdiffuser framework can fruitfully be used to describe and identify influential individuals in diverse contexts. Influence also appears to be a relatively trait-like individual difference rather than a matter of unique fit to a particular country or culture.

DEVELOPMENT OF ECONOMIC ABUSE SCALE (EAS); ESTABLISHING CONTENT VALIDITY OF EAS

Economic abuse involves behaviors that control a woman’s ability to acquire, use, and maintain economic resources, thus threatening her economic security and potential for self-sufficiency (Adams, Sullivan, Bybee, & Greeson, 2008). Woman battering is a prevalent social problem committed against millions of women each year. Battering involves psychological abuse, physical abuse, and economic abuse as well. Economic abuse is the area which is less focused as compared to other forms of battering. The objective of present study was to develop an indigenous scale that would explore the phenomenon of economic abuse faced by married Pakistani women as currently there is no such indigenously developed measure of economic abuse available in Pakistan. Present study was conducted in two phases. In the first phase, a pool of items was generated. In phase two, Content Validity for EAS was established. The Scale CVI was 0.93. All 41 items were retained and were transformed into a 5-point rating scale. The psychometric properties of scale will be established using factorial validity.

Psychometric properties and measurement invariance of the Chinese version of the cognitive emotion regulation questionnaire‐short in patients with cancer

AbstractObjectiveThe study aimed to evaluate the psychometric properties and measurement invariance (MI) of the Chinese version of the cognitive emotion regulation questionnaire‐short (CERQ‐short) in cancer patients.MethodsThis cross‐sectional study included 505 cancer patients from mainland China. In addition to sociodemographic and clinical characteristics, the CERQ‐short and the distress thermometer were included in the study measures.ResultsItem analysis indicated a promising result. And the results of CFA indicated that the CERQ‐short demonstrated satisfactory factorial validity in cancer patients. Cronbach's alpha coefficients were between 0.663 and 0.910, while McDonald's omega coefficients were between 0.664 and 0.910. The CERQ‐short had sufficient convergent, discriminant and concurrent validity among cancer patients. Lastly, MI supported that the CERQ‐short demonstrated strong measurement equivalence across gender, residence and age.ConclusionsThis study shows that the Chinese version of the CERQ‐short has convincing psychometric properties and MI, which supports its use in cancer patients.

Psychometric characteristics of a questionnaire to assess perceived disability in people with epilepsy

It has been determined that quality of life in epilepsy is closely related to the perceived disability experienced by individuals with the diagnosis. However, this measure is seldom considered in healthcare processes. The objective of the present study is to establish the psychometric properties of the Perceived Disability Questionnaire in individuals diagnosed with epilepsy within a Latin American context. A cross-sectional, analytical study was conducted involving 325 participants, aged 12 years and older (M 40.42 years), individuals diagnosed with epilepsy in Colombia. The main psychometric properties of the instrument were explored to account for its factorial validity and reliability. The Perceived Disability Questionnaire exhibits high reliability (α = 0.878) and the three subscales comprising the final version of the questionnaire (Dissatisfaction, Pessimism, and Self-Disdain) explain 45.393 % of the total variance in relation to beliefs of disability associated with the diagnosis of epilepsy; the questionnaire significantly correlates with the Quality of Life in Epilepsy Inventory (QOLIE-10). Adequate psychometric properties of the instrument are found, which allows for its proposal as a tool in epilepsy care processes within the Colombian context.

Psychometric Properties of the Chinese Version of the Core Symptom Index: A Study among Chinese Parents of Children with Autistic Spectrum Disorders.

(1) Background: Parents of children with autism spectrum disorders often experience psychological distress, which can affect the quality of childcare they provide. It is crucial to screen for psychiatric symptoms among these parents. The core symptom index (CSI) is a widely recognized tool used to assess general symptoms, including depression, anxiety, and somatic issues. It has proven validity and reliability across diverse Thai populations. Given the cultural similarities between Thai and Chinese populations, the CSI has been successfully implemented within the Chinese population. Nevertheless, it is crucial to research its validity and reliability in the general Chinese population. This study aimed to investigate the psychometric properties of the Chinese version of the CSI among parents of children with autism spectrum disorders using confirmatory factor analysis (CFA). (2) Methods: A total of 794 Chinese parents raising children with autism participated in this study. All completed the CSI, along with the social inhibition subscale of the Interpersonal Problems Inventory and the Couple Satisfaction Index. Factorial validity was assessed using CFA to determine how well the bifactor three-factor model fits the data. Various structural models were compared using model fit indices. Convergent and discriminant validity were examined by exploring correlations with the social inhibition subscale and the Couple Satisfaction Index. Invariance testing of the CSI was conducted across multiple groups based on gender, age, and education using CFA. The reliability of the CSI was evaluated using McDonald's omega coefficients. (3) Results: The bifactor model emerged as the best-fitting model for the data, suggesting that the total score of the CSI adequately represents overall psychiatric symptoms. The CSI exhibited significant correlations with the social inhibition subscale (r = 0.41, p < 0.01) and smaller correlation coefficients with the Couple Satisfaction Index (r = -0.16, p < 0.05), indicating both convergent and discriminant validity. The invariant test results support scalar invariance levels based on gender and age but only partial invariance for education. The Chinese version of the CSI demonstrated high consistency, with McDonald's omega coefficients ranging between 0.86 and 0.95. (4) Conclusions: The bifactor model of the Chinese version of the CSI is validated, making it a suitable tool for measuring depression, anxiety, and somatization symptoms among parent(s) of children with autism spectrum disorders. Further research on other Chinese populations is encouraged.

From loss to disorder: The influence of maladaptive coping on prolonged grief

Research indicates that post-bereavement coping strategies can be adaptive or maladaptive. Understanding which strategies lead to poorer outcomes is an important clinical and theoretical question with the potential to guide intervention.The Oxford Grief – Coping Strategies scale was developed from interviews with bereaved people with and without prolonged grief disorder (PGD) to assess the frequency of maladaptive cognitive and behavioural strategies after bereavement. Factorial and psychometric validity were assessed using exploratory and confirmatory factor analysis (N = 676). A three-wave cross-lagged panel model (N = 275) was used to assess the predictive validity of the tool in explaining symptoms of PGD.Results supported a four-factor solution (Avoidance, Proximity Seeking, Loss Rumination, Injustice Rumination) with good psychometric properties. The OG-CS predicted prospective symptoms of PGD in the short-term (6–12 months) and long term (12–18 months), controlling for baseline symptoms and autocorrelations. Subscale analyses demonstrated that the use of coping strategies predicted ICD-11 PGD in both the short-term and the long-term. However, avoidance was not predictive of outcomes early in the grieving process. At 6–12 months, avoidance predicted PGD at 12–18 months.

Structural Validity of the Interpersonal Behaviors Questionnaire in Greek University Sport-Students

The examination of the interpersonal behaviors of undergraduate student-athletes can contribute to the research on the perceptions of students for satisfaction and frustration of basic psychological behaviors by teachers in the context teaching classes. Aim of this study was to translate into Greek and investigate the factorial validity and internal consistency of the Interpersonal Behavior Questionnaire (IBQ; 24-item six factors). 252 full-time undergraduate student-athletes (125 males and 127 females) were used ranging in age 18 to 38 years. The results of CFA showed a good fit of the data to the model, while the multi-sample results indicated invariance for factor loadings and correlations between male and female samples. Internal consistency coefficients Cronbach alpha and interclass correlation were moderate significant. In conclusion, the IBQ-Gr version has valid and reliable psychometric properties and can be applied to examination of the perceptions interpersonal behaviors others into Greek population.

Development of the medical adherence scale in adolescents using psychotropic medication and evaluation of validity and reliability in Turkish population

PurposeAlthough treatment non-adherence is relatively high among adolescents, there is a need for standardized measurement tools that measure adherence to treatment in adolescents. This study aimed to develop a new measurement tool to assess the adherence to treatment of adolescents with mental disorders who use psychotropic medication. MethodsThe data of this methodologically designed study were collected between 01.04.2022 and 01.07.2023 in the Department of Child and Adolescent Psychiatry of a university hospital in the Aegean Region of Turkey. The Medication Adherence Reporting Scale and Adolescent Medical Adherence Scale draft form were used for data collection. The scale items were formed from the themes, sub-themes, and statements in the qualitative study that the researchers had conducted with adolescents with mental disorders and their parents, clinicians' experiences, and systematic reviews and meta-synthesis in the literature. The study sample consisted of 95 adolescents with mental disorders. Exploratory factor analysis was performed with Varimax rotation to determine the factorial construct validity of the scale. Internal consistency analyses were performed in reliability analyses, and Cronbach's alpha coefficient was used. ResultsThe mean age of the adolescents was 14.18 years (1.81); 50.5% were male, and 96.8% were attending school. When the mental disorder diagnoses were analyzed, 65.3% of the adolescents were being followed up with Attention Deficit and Hyperactivity Disorder diagnoses, and 58.8% were using stimulants. The 12-item form of the Adolescent Medical Adherence Scale was found to have a three-factor structure with item-total correlation values ranging between 0.26 and 0.66, and these factors were named functionality, responsibility in treatment, and medication adherence. Factor loadings ranged between 0.44 and 0.86, and the items explained 62.98% of the total variance. The internal consistency coefficients of the scale were between 0.69 and 0.83 for the subscales and 0.82 for the total scale. ConclusionBased on the analysis and results used in this study, the Adolescent Medical Adherence Scale is a valid and reliable new measurement tool. Practice implicationsThis tool can be used in clinical settings to evaluate adolescents' treatment adherence and prognosis. Clinical studies conducted with adolescents can also determine adherence to treatment and affecting factors.

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

BackgroundChildren 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.MethodsBoth 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).ResultsOverall, 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.ConclusionsThe 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.Trial registrationADOPT Online: German Clinical Trials Register (DRKS) DRKS00014963.

Individual and Organizational Ductility: Conceptualization, Development, and Validation of a New Scale.

In this article, we conceptualize a new construct named "ductility" and propose a measurement instrument. We examine psychometric properties-the factorial validity and reliability of the Ductility Scale in Italy. The results of exploratory factor analysis showed that the scale has a two-factor structure, namely, individual and organizational ductility. The scale reliability was excellent for both dimensions (individual ω = 0.82; organizational ω = 0.85). The participants were employees from private and public organizations (n = 466). We tested the construct validity of the Ductility Scale. The invariance of the measurement model tested via multigroup confirmative factor analysis showed that the Ductility Scale was invariant across gender. In addition, we found ductility to be positively related to proactive personality and work engagement. These preliminary results show that the Ductility Scale is a reliable and valid measure. In addition, our findings illustrate the potential usefulness of the ductility construct via the newly developed scale.

Method: Quota sampling was used to validate the Chinese version of the instrument. Data were collected from 1,000 social workers and students in mainland China to test the reliability and validity of the translated SWCCSA. Results: The Chinese version of SWCCSA was finalized with three-factor dimensions with 21 items after exploratory factor analysis and confirmatory factor analysis. The assessment presented good factorial validity and reliability. Discussion: The revised three-factor dimensional Chinese version of SWCCSA developed by this study is a reliable and valid measurement instrument for future assessment of social work practitioners’ and students’ cultural competence in China.

Paradox of Self-Stigma: Psychometric Validation for the Portuguese Population in Poverty

Stigma is the attribution of labels to individuals to diminish or weaken them in society. The internalized stigma affects self-stigma, which influences their self-concept and confidence. The aim of this study was to translate and validate the PaSS-24 (Paradox of Self-Stigma Scale) for the population living in poverty in Portugal. The scale was translated using the back-translation technique, and the questionnaire was answered online by 357 people living in poverty in Portugal. The results of the exploratory factor analysis show excellent factorial validity, maintaining the factors of the original scale, and the results of the internal consistency, convergent and discriminant validity show excellent psychometric properties.

Psychometric assessment of the 10-item Thai version of the Experience in Close Relationship-Revised for Adolescents (ECR-R-10-AD)

The 18-item version of the Experiences in Close Relationships-revised (ECR-R-18) is a valid and reliable scale used among Thai adolescents. However, it revealed problematic items that impacted the scale’s internal consistency. The study aimed to achieve two objectives: (1) develop a new, shorter scale by retaining only highly loaded items equally between attachment anxiety and attachment avoidance, and (2) evaluate the psychometric properties of the shorter ECR-R version compared to the existing 18-item scale. Objective 1 was achieved through Study 1, involving 204 youths aged 16–18 years (64% female). All participants completed the 18-item ECR-R, and exploratory factor analysis was conducted to identify suitable items for the new ECR-R-AD. Objective 2 was fulfilled in Study 2, which included a total of 443 students in grades aged 15–18 years old (88% female) from Thai boarding schools in Northern Thailand. All participants completed both the 18-item ECR-R, and confirmatory factor analysis of both the existing 18-item and the new shorter scale was performed and compared. Additional measures including the Rosenberg Self-Esteem Scale, Perceived Stress Scale-10, and Relationship Questionnaire were completed alongside the ECR-R to assess convergent, discriminant, and criterion validity. The invariance test for the new ECR-R across genders was conducted using multigroup confirmatory factor analysis. For objective 1, Study 1 developed a new scale called "ECR-R-10-AD" with 10 items, comprising 5 for attachment anxiety and 5 for attachment avoidance. The McDonald’s omega values were 0.866 for avoidance and 0.823 for anxiety subscales. The corrected correlation between the ECR-R-18 and ECR-R-10-AD was significant. For objective 2, Study 2 found that the first-order two-factor solution model fit the data best for the ECR-R-10-AD. Convergent, discriminant, and criterion validity with other measurements and invariance tests based on sex were established for the ECR-R-AD. The ECR-R-10-AD provided sufficient psychometric properties among Thai adolescents. Factorial validity, convergent validity, and measurement invariance were established. As the ECR-R-10-AD is brief, it can be administered with less burden. Limitations and future research were discussed.

Re-assessing the assessment of fears of positive and negative evaluation: Scale development and psychometric evaluation of the Bivalent Fear of Evaluation Scale (BFOES)

The bivalent fear of evaluation (BFOE) model of social anxiety divides fear of evaluation into two distinct valences: fear of positive evaluation (FPE) and fear of negative evaluation (FNE). However, there is evidence that the two most widely utilized and psychometrically supported measures of FNE and FPE contain items which are ambiguous with regard to valence of evaluative fear. To formally address this, the BFOE Scale (BFOES) was developed, by merging items from measures of FNE and FPE into a single scale with an integrated response format. The present studies examined the psychometric profile of the BFOES across a large pooled archival dataset (N = 2216), which included approximately 10 % (n = 224) patients with social anxiety disorder (SAD). The factorial validity, internal consistency, and construct validity of the BFOES were examined. Additionally, item response theory analyses were employed for the purpose of merging items from self-report scales which utilized different Likert-type response formats. Results from both studies provided support for the psychometric profile of the BFOES. The implications of the BFOES for the assessment of social anxiety, and theoretical models of fear of evaluation and SAD, are discussed.

Development and validation of a questionnaire about reasons for academic cheating by nursing students: A cross-sectional study.

Cheating behavior is spreading among nursing students worldwide, necessitating the development of a validated questionnaire evaluating the reasons for such behavior. Nursing students (N = 482) from 2 universities in Saudi Arabia participated in this observational study. A survey containing items on socio-demographics and the 33-item Reasons for Cheating Scale (RCS) was completed by the respondents. The RCS had a 1-factor structure; the model fit indices were similar between the 1-, 2-, and 3-factor models, but the inter-factor correlations were too high for the 2- and 3-factor models. The measures of the quality of the factor score estimates were as follows: factor determinacy index, 0.987; expected a posteriori marginal reliability, 0.974; sensitivity ratio, 6.178; and expected percentage of true differences, 97.3%. The measures of the closeness to unidimensionality for the overall RCS were as follows: unidimensional congruence, 0.957; explained common variance, 0.875; and mean item residual absolute loading, 0.223. The intraclass correlation coefficient and McDonald's omega were 0.96 (CI: 0.93-0.98) and 0.962 (95% CI: 0.958-0.967), respectively. The severity score, infit, and outfit ranged from -0.847 to -2.015, 0.813 to 1.742, and 0.837 to 1.661, respectively. For all RCS items, the thresholds ranked τi1 < τi2 < τi3 < τi4 and showed invariance between the sexes. The RCS showed robust psychometric validity for both classical and item response theory parameters. It also had excellent test-retest reliability, internal consistency, item discrimination, factorial validity, measurement invariance, and ordered threshold level for the responses. Therefore, the RCS is a valid and reliable tool for assessing cheating behavior among nursing students.
