Psychometric Properties of the Primary Care PTSD Screen for DSM-5: Findings From Family Members of Chinese Healthcare Workers During the Outbreak of COVID-19

Background: Minimal research has examined utility of PC-PTSD-5 in family members of frontline medical workers. The aims of our study were to develop and elucidate the psychometric properties of the Chinese version of the PC-PTSD-5 and to determine its usefulness in screening for possible PTSD in relatives of Chinese healthcare workers during the COVID-19.Methods: We conducted a cross-sectional research in the relatives of medical staffs working in a general hospital during the COVID-19. Descriptive analysis was used to characterize demographic information of family members to find factors associated with PTSD symptoms. For reliability test, the internal consistency of PC-PTSD-5 was accessed using Cronbach's alpha coefficient. A validity test was assessed by Pearson's correlation between scales. A receiver operating characteristic (ROC) curve was used to evaluate the optimal cutoff score with the maximum Youden Index in this study.Results: The result of demographic information indicated that gender and the type of work undertaken by medical staff in the family have a potential impact on the PTSD symptoms of medical staff's family members. Cronbach's alpha coefficient of PC-PTSD-5 was 0.83, indicating the high reliability. Good validity was also demonstrated by Pearson coefficient. By calculating the Youden index, a cutoff score of 2 was found to be optimal in our study, with sensitivity of 80.74% and specificity of 88.43%.Conclusions: Our study has demonstrated the robust psychometric strengths of the PC-PTSD-5, introducing a reliable tool for screening PTSD among vulnerable and neglected families of these medical workers.

Abstract Background Given the importance of screening pregnant women’s distress, it was intended to investigate the psychometric properties of the Persian version of the Tilburg Pregnancy Distress Scale (TPDS-P) for screening pregnancy distress. Methods This methodological psychometric study was conducted with participation of 360 pregnant women. The TPDS was translated into Persian. Factor analysis was used to investigate the construct validity. The results of the correlation test between the results of the two questionnaires, Depression Anxiety Stress Scales-21 (DASS-21) and TPDS-P, were used to determine the criterion validity of TPDS-P. Internal consistency of the items was calculated by the Cronbach's alpha coefficient. Stability of the results was examined by test-retest method and Intra-class Correlation Coefficient (ICC) was calculated. Examining the structure of the factors derived from exploratory factor analysis, fitness of the model was done through confirmatory factor analysis. Statistical analysis was done using SPSS software. Results Kaiser-Meyer-Olkin (KMO) was 0.846 (p = 0.001). Sixteen items of TPDS-P accounted for 51.42 percent variances. The TPDS-P exhibited appropriate fitness. There was poor to moderate but significant direct correlation between the subscales of DASS-21 and TPDS-P. Cronbach’s alpha coefficient of the TPDS-P was 0.81 and ICC was 0.70. Conclusions TPDS-P, with appropriate validity and reliability, can be used as a practical scale to evaluate women's distress during pregnancy in Farsi-speaking societies.

Abstract Purpose The aim of this study was to translate the questionnaire for urinary incontinence diagnosis (QUID) into German and to assess its psychometric properties in German-speaking women with urinary incontinence (UI). The QUID contains two subscales to measure symptom severity of stress urinary incontinence (SUI) and urge urinary incontinence (UUI) and to distinguish between both forms. Methods A total of 161 women with UI completed the QUID and the King’s Health Questionnaire (KHQ), each in the German version. To examine construct validity Spearman’s correlation coefficients between both questionnaires were computed. Furthermore, the internal consistency (Cronbach’s alpha) of the QUID and its criterion validity were examined. Looking at criterion validity, sensitivity, specificity, ROC curves, and Youden-indexes were computed for both subscales. Results The QUID showed good construct validity by strong correlations with related domains of the KHQ. Cronbach’s alpha values were good for both subscales of the QUID (SUI-subscale: 0.76; UUI-subscale: 0.86). Sensitivity and specificity were 83% (95% CI, 0.72–0.9) and 45% (95% CI, 0.25–0.67) for the SUI-subscale and 83% (95% CI, 0.7–0.91) and 56% (95% CI, 0.4–0.72) for the UUI-subscale. Youden-index was 0.28 for the SUI-subscale and 0.39 for the UUI-subscale at the given cut-off values. Conclusion Psychometric properties of the German-language QUID are principally good and support its use in the German-speaking area. However, the modest specificity when distinguishing between SUI and UUI should be taken into account. Trial registration number: DRKS00018777 (date of registration: 16-January-2020).

Background: After introducing the emotional schema model, two questionnaires are proposed to assess this structure. This study is the first validation research on the Relationship Emotional Schema scale (RESS) worldwide. Objectives: The present study aimed to assess the factor structure and psychometric properties of RESS among Iranian victims of domestic violence. Materials and Methods: This study used a correlational method, and the research population encompassed couples with the experience of domestic violence, who had referred to the Forensics Center of Sari Province in 2018. The sample size of the study was determined to be 227 persons selected by the convenience sampling method. To implement RESS for Iranian population after back translation, a pilot study was conducted on 50 persons. Moreover, internal consistency and exploratory factor analysis were performed to check its structure validity. Results: Fourteen items have a significant correlation with the scores of the relevant subscale (negative and positive relationship emotional schema). The reliability of these two dimensions was acceptable, as confirmed by Cronbach’s alpha coefficient with a range of 0.68 to 0.74. The total value of Cronbach’s alpha coefficient was 0.71. Exploratory factor analysis revealed four factors of RESS. Furthermore, a two-factor structure was extracted, and the correlation between items confirmed the structure validity of the scale. Convergent validity analyses revealed that negative and positive relationship emotional schemas had a significant correlation with the domestic violence domains and its total score and with neuroticism and extraversion. Conclusions: According to the present findings, RESS can be utilized in research and clinical practice.

Abstract Introduction: Ageing entails a series of neuroanatomical and neurophysiological changes in some cognitive processes that directly affect the daily life and autonomy of a person. We believe it is necessary to have tools that assess the cognitive functions that are essential for carrying out daily activities in an independent manner. The aim of this study was to translate the Everyday Cognition Battery (ECB) scale into Spanish, adapt it to the sociocultural context of Spain, and validate it by testing the psychometric properties, i.e., the reliability and validity of the translated version.Methods: The translation and adaptation of the ECB into Spanish was carried out following the method recommended by Beaton et al., the process concluding with a pilot test to ensure that subjects were able to understand the scale correctly. Between March and October 2019, the study population voluntarily completed the translated version of each of the four subscales that make up the battery of tests. The translated version was validated by analysing its psychometric properties, using reliability or internal consistency tests assessed with Cronbach's alpha coefficient and validity tests analysed using correlation tables and Spearman's correlation coefficient. The scale considered to represent the gold standard in the assessment of cognition was the Rapid Assessment of Cognitive Functions (RACF), and to assess Instrumental Activities of Daily Living (IADL) this was the Lawton and Brody Index. Results: The total study population included 226 subjects, of which 52 participants were excluded, resulting in a study sample size of 174 older adults. The recognition, inductive reasoning and computation span tests showed good reliability (Cronbach's alpha coefficient of >0.827, >0.836, and >0.823, respectively), while the knowledge test showed questionable reliability with a Cronbach's alpha coefficient of >0.615. The validity analysis demonstrated that all the combinations of correlations of the different scales were significantly and positively related to one another. Conclusions: The Spanish version of the ECB tool is socially and culturally equivalent to the original version, and both its validity and reliability for assessing everyday cognition in older adults have been demonstrated.

Abstract Introduction As a result of high transmission and mortality rates, the Covid-19 pandemic has led to a worldwide health crisis, isolation, and widespread fear, therefore negatively influencing people’s quality of life (QOL). The goal of the present study was to examine the psychometric properties (validity and reliability) of the Persian version of the COVID-19-Impact on Quality of Life (COV19-QoL) scale. Methods After translating the scale using the forward–backward method, face and content validly was qualitatively assessed. Then the scale was distributed to 488 individuals from the general population via online platforms. Construct validity was assessed using exploratory (EFA) and confirmatory (CFA) factor analysis. In addition, internal consistency was examined using Cronbach’s alpha coefficient and McDonald’s omega, relative stability was assessed using interclass correlation coefficient (ICC), and absolute stability was calculated through examination of standard error of measurement. Results The EFA revealed one factor that explained 55.96% of the total variance of the scale. Internal consistencies of 0.823 and 0.882 were found using Cronbach’s alpha coefficient and McDonald’s omega, respectively. In addition, an ICC of 0.837 (with a two-week interval) was found. Covid-19 had a greater impact on the QOL of healthy participants than that of those with underling conditions (p = 0.004), and also on the QOL of single participants than that of married ones (p = 0.032). Conclusion The Persian version of the COV19-QoL is a valid and reliable instrument that can be used to examine the impact of Covid-19 on QOL.

Background The National Institutes of Health Stroke Scale (NIHSS) is a validated tool for assessing the severity of stroke. It has been adapted into several languages; however, a Polish version with large-scale psychometric validation, including repeatability and separate assessments of anterior and posterior stroke, has not been developed. We aimed to adapt and validate a Polish version of the NIHSS (PL-NIHSS) while focusing on the psychometric properties and site of stroke. Methods The study included 225 patients with ischemic stroke (102 anterior and 123 posterior circulation stroke). Four NIHSS-certified researchers estimated stroke severity using the most appropriate scales to assess the psychometric properties (including internal consistency, homogeneity, scalability, and discriminatory power of individual items) and ultimately determine the reliability, repeatability, and validity of the PL-NIHSS. Results The PL-NIHSS achieved Cronbach’s alpha coefficient of 0.6885, which indicates moderate internal consistency and homogeneity. Slightly more than half of the individual items provided sufficient discriminatory power (r > 0.3). A favorable coefficient of repeatability (0.6267; 95% confidence interval: 0.5737–0.6904), narrow limits of inter-rater agreement, and excellent intraclass correlation coefficients or weighted kappa values (> 0.90), demonstrated high reliability of PL-NIHSS. Highly significant correlations with other tools confirmed the validity and predictive value of the PL-NIHSS. In posterior stroke, the PL-NIHSS achieved the required Cronbach’s alpha coefficient (0.71070). Additionally, stroke location did not affect other psychometric features or instrument reliability and validity. Conclusions We developed a valid and reliable tool for assessing stroke severity in Polish-speaking participants. Moderate psychometric features were emphasized without limiting its clinical applications.

Background and Aims: Mentalized affectivity is a new approach that expresses the process of emotion regulation through a dynamic perspective. Since social-cognitive variables and cultural context play a major role in the process of mentalized affectivity, the present study aimed to assess the psychometric properties of the Mentalized Affectivity Scale in Iran. Materials and Methods: A total of 447 students were selected via the convenience sampling method. The Persian version of Mentalized Affectivity Scale was administered simultaneously with other scales. exploratory and confirmatory factor analyses was used to evaluate the validity of the scale. Moreover, convergent validity and divergent validity of this scale were assessed with other scales. The reliability of the scale was calculated by Cronbach's alpha, coefficient theta, and composite reliability. Results: The results of exploratory factor analysis showed four factors of emotion recognition, emotion processing, emotion tracing, and emotion expression. The significant correlation of factors with the used scales pointed to the content validity and divergent validity of the scale. Cronbach's alpha coefficient for the entire scale was 0.93. The composite reliability of the factors was in the range of 0.82-0.89, and the coefficient theta of the scale was reported as 0.98. With respect to average variance extracted (AVE) greater than 0.5 and composite reliability greater than 0.8, the convergent validity of the factors was confirmed. Conclusion: As evidenced by the obtained results, the Persian version of the Mentalized Affectivity Scale is a valid scale in the field of emotion regulation and social cognition that can be used for Iranian populations. The factor structure includes four factors.

Abstract Background Antiretroviral therapy (ART) has the most effective treatment for people with HIV, but its effectiveness depends on the individual medication adherence. Morisky Medication Adherence Scale (MMAS-8) is one of the most widely used scales to assess patient adherence. Thus, we aimed to validate a Portuguese version of MMAS-8 and determine its psychometric properties in HIV positive patients. Methods A cross-sectional survey was conducted in Centro Hospitalar Universitário São João (Porto, northern Portugal) at the infectious diseases department. After authorization to use the scale - granted by the author - and, a standard forward-backwards procedure to translate MMAS-8 to Portuguese, the questionnaire was applied to 233 patients with HIV doing ART. Reliability was assessed using Cronbach's alpha and test-retest reliability. Three levels of adherence were considered: 0 to < 6 (low), 6 to < 8 (medium), 8 (high). Results In the studied sample, the mean age was 45.03 years (SD = 11.63), 80.3% men, 19.3% women and 1 transgender, and 53.8% had ≤9 years of education. The mean number of prescribed ART per patient was 1.76. The mean score for the medication adherence scale was 7.29 (SD = 6.74). For the reliability analysis, 12 patients were excluded due to missing data (n = 221). Regarding the level of adherence, 22.5% were low adhering, 71.6% medium and 5.9% high. Corrected item-total correlations showed that 1 item does not correlate very well with the overall scale and was dropped. Scale reliability analysis for the remaining 7 items revealed an overall Cronbach's alpha of 0.661. Women had a protective effect on adherence (OR = 0.31;95%CI:0.15-0.66). Number of years doing ART, age of participants, and type of residence didn't show to be correlated with adherence. Conclusions MMAS-8 is a reliable and valid measure to detect patients at risk of non-adherence. A satisfactory Cronbach's alfa (0.661) was obtained. In general, adherence to medication was medium or high. Key messages This scale can be applied nationwide in other different hospitals, as it could serve as a tool for measuring adherence to ART that can allow for better health care to the ones that are low adhering. A Portuguese version of the MMAS-8 was created for measuring adherence to ART that maintained a similar structure to the original MMAS-8 and good psychometric properties.

The purpose of this study was to evaluate the psychometric properties of the Brazilian Scale for the Assessment of Self-Care Behaviors with Arteriovenous Fistula in Hemodialysis. Cross-sectional validation study, followed the recommendation provided by Sousa and Rojjanasrirat. Content validity, explanatory and confirmatory factor analyses used to check validity and Cronbach’s alpha was the reliability measure. Three hundred hemodialysis patients with arteriovenous fistula were included in the study. The expert committee assessed the content validity. Exploratory factor analysis confirmed the same two-factor structure found for the original scale, explaining 60.10% of the variance. Such solution was checked by confirmatory factor analysis with Cronbach’s alpha equal to 0.920, 0.810, and 0.884 for the overall scale, the self-care in management of signs and symptoms and the self-care in prevention of complications subscales respectively. The scale has good psychometric properties to assess self-care behaviors and can be used with Brazilian patients on hemodialysis with arteriovenous fistula.
