Adaptation and Validation of the Spanish Version of the Everyday Cognition Battery Scale for Assessing Everyday Cognition in Older Adults

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.

Background: Stroke causes a wide variety of clinical manifestations that may have a negative impact on quality of life. Therefore, it is very important to use specific instruments for measuring quality of life in individuals who suffered a stroke. The aim of this study was to develop a psychometrically validated Spanish version of the Newcastle stroke-specific quality of life measure (NEWSQOL). Methods: A psychometric validation of the Spanish version of the NEWSQOL questionnaire was carried out in 159 patients. The reliability (intraclass correlation coefficient and Cronbach’s alpha coefficient), validity (factorial analysis and Spearman’s coefficient), feasibility (response rate), and the ceiling and floor effects were calculated. Results: Internal consistency showed that Cronbach’s alpha coefficient was 0.93. The test–retest reliability was high or excellent for all domains (range 0.71–0.97 p < 0.001). The response rate of the questionnaire was 100% and the average administration time was 20.5 (±7.2) min. No ceiling effect was detected and two domains (pain and vision) may have a significant potential for floor effect. Construct validity showed that all the variables are important enough to keep them all in the questionnaire. Concerning convergent construct validity, a high correlation was found with the Nottingham Health Profile, the Barthel Index, and the Modified Rankin Scale. Conclusion: The Spanish version of the NEWSQOL questionnaire is reliable, valid, and feasible to evaluate quality of life in the Spanish population.

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.

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.

Background: Sexual satisfaction is a complex and multidimensional concept. It encompasses physical, emotional, relational and cultural dimensions, and constitutes an essential component of sexual health, as well as an indicator of quality of life and wellbeing. The Sexual Satisfaction Scale for Women (SSS-W) was designed in the United States, and it is a valid and reliable tool to measure women’s sexual satisfaction. Aim: The aim of this study was to culturally adapt and translate the SSS-W into Spanish and analyze its psychometric properties. Methods: First, the original instrument was culturally adapted and translated from English to Spanish. Then, we tested the psychometric properties of the instrument in its Spanish version in a sample of 316 women who attended a family planning clinic in Logroño, Spain. Internal consistency reliability of the whole scale and each subscale separately was measured using Cronbach’s alpha. Factorial validity of the SSS-W in its Spanish version was analyzed using exploratory factor analysis through the Kaiser–Meyer–Olkin measure of sample adequacy and Bartlett’s Sphericity test. Results: The Cronbach’s alpha coefficients of the total scale and each subscale were satisfactory (>0.7). Exploratory factor analysis confirmed the five hypothetical dimensions of the scale in its Spanish version. The five dimensions (contentment, communication, compatibility, relational concern, and personal concern) explained 60% of the total variance of the scale; factor analysis using varimax rotation revealed strong loads in each of the five components. Conclusions: The SSS-W in its Spanish version is a valid and reliable tool to assess sexual satisfaction in Spanish women of reproductive age and, therefore, can be used both in clinical practice and for the investigation of sexual health.

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.

Objectives: The increasing trend in aging population raises the need to pay attention to the daily activities of the elderly and their social support as an effective factor in promoting their health. This study aims to investigate the correlation of perceived social support and demographic variables with the Activities of Daily Living (ADL) in older adults living in rural communities in Iran. Methods & Materials: This is a descriptive-analytical study with cross-sectional design conducted on 430 elderly people aged ≥60 years living in a rural community in Iran (Bayza county located 45 km away from Shiraz city) who were selected using a convenience sampling method. Procidano & Heller’s Perceived Social Support - Family Scale (PSS-Fa) and the ADL scale for the elderly were used for data collection. The ADL questionnaire’s internal consistency by calculating Cronbach’s alpha coefficient was obtained 0.96. The PSS-Fa with a Cronbach’s alpha coefficient ranging from 0.88 to 0.91 has acceptable internal consistency. The reliability of its Persian version using Cronbach’s alpha coefficient was obtained 87%. Data were analyzed in SPSS V. 25 software using multivariate ANOVA and regression analysis. Results: The mean±SD age of the participants was 69.67±7.067 years. The mean score of PSS-Fa and the ADL scale was reported 16.55± 5.16 and 55.10±3.07, respectively. Perceived social support, education and age had significant effect correlation with the ability to perform ADL in the elderly (P<0.001), while marital status and gender showed no significant correlation (P>0.05). The age factor was inversely correlated with the ability to perform ADL; hence, the independence of older adults decreases with the increase of age. Conclusion: Many demographic variables and social support affect the ability to perform ADL in the elderly. Social support can be used as a social investment to improve the quality of life of the elderly. Therefore, considering that one of the duties of health care providers is to improve the health status of the elderly, it is necessary for health care providers to increase social support and maintain and promote a healthy and active life for them through educational programs and periodic physical examinations.

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.
