A factor analytic assessment of the English translation of the neuropsychological vertigo inventory (NVI).
Ontology highlight
ABSTRACT:
Method: The English language adaptation of the NVI (referred to here as the NVIe) was administered to an unselected sample of 280 patients that were being evaluated for dizziness and/or vertigo in a tertiary care dizziness clinic. The individual item scores from the NVIe were subjected to an exploratory factor analysis (EFA).
Results: The results of the data analysis supported a 22-item NVIe consisting of 4 constructs: affective state, temporal memory, spatial memory, visual spatial cognition.
Conclusions: The NVIe is a new tool for screening cognitive constructs that may be affected by vestibular impairments. Prior to clinical implementation of the NVIe, additional studies of reliability and convergent validity are needed.

Project description:Bi directionality, a common practice in translation industry, refers to the transfer from L2 to L1 (direct translation) or L1 to L2 (inverse translation). Several studies have investigated relativization in direct or inverse translations, but few studies have considered relativization in the two translation directions. Following a hypothesis-based observational design, this study investigated the Arab undergraduates' performance on the direct and inverse translation of relativization. The study sample comprised undergraduates in the College of Languages and Translation (n = 36) and was divided into two groups (students of English and students of translation). The results showed statistically significant differences between students' performance on direct and on inverse translation (t (35) = 14.906, ≤0.05), indicating that inverse translation was more difficult than direct translation. The independent-sample t-test revealed that the students of translation outperformed the English students in direct and inverse translations. Despite the two groups' low performance on inverse translation, both considered that direct and inverse translations were equally 'somewhat difficult'. The paper concluded with suggestions that could guide the design of the translation courses and selecting teaching methods that could improve students' translation of relativization.

Project description:The COPE Inventory (Carver et al., 1989) is the most frequently used measure of coping; yet previous studies examining its factor structure yielded mixed results. The purpose of the current study, therefore, was to validate the factor structure of the COPE Inventory in a representative sample of over 2,000 adults in Slovakia. Our second goal was to evaluate the external validity of the COPE inventory, which has not been done before. Firstly, we performed the exploratory factor analysis (EFA) with half of the sample. Subsequently, we performed the confirmatory factor analysis with the second half of the sample. Both factor analyses with 15 factor solutions showed excellent fit with the data. Additionally, we performed a hierarchical factor analysis with fifteen first-order factors (acceptance, active coping, behavioral disengagement, denial, seeking emotional support, humor, seeking instrumental support, mental disengagement, planning, positive reinterpretation, religion, restraint, substance use, suppression of competing activities, and venting) and three second-order factors (active coping, social emotional coping, and avoidance coping) which showed good fit with the data. Moreover, the COPE Inventory's external validity was evaluated using consensual qualitative research (CQR) analysis on data collected by in-depth interviews. Categories of coping created using CQR corresponded with all COPE first-order factors. Moreover, we identified two additional first-order factors that were not present in the COPE Inventory: self-care and care for others. Our study shows that the Slovak translation of the COPE Inventory is a reliable, externally valid, and well-structured instrument for measuring coping in the Slovak population.

Project description:We present Chinese translation norms for 1,429 English words. Chinese-English bilinguals (N = 28) were asked to provide the first Chinese translation that came to mind for 1,429 English words. The results revealed that 71 % of the English words received more than one correct translation indicating the large amount of translation ambiguity when translating from English to Chinese. The relationship between translation ambiguity and word frequency, concreteness and language proficiency was investigated. Although the significant correlations were not strong, results revealed that English word frequency was positively correlated with the number of alternative translations, whereas English word concreteness was negatively correlated with the number of translations. Importantly, regression analyses showed that the number of Chinese translations was predicted by word frequency and concreteness. Furthermore, an interaction between these predictors revealed that the number of translations was more affected by word frequency for more concrete words than for less concrete words. In addition, mixed-effects modelling showed that word frequency, concreteness and English language proficiency were all significant predictors of whether or not a dominant translation was provided. Finally, correlations between the word frequencies of English words and their Chinese dominant translations were higher for translation-unambiguous pairs than for translation-ambiguous pairs. The translation norms are made available in a database together with lexical information about the words, which will be a useful resource for researchers investigating Chinese-English bilingual language processing.

Project description:ObjectiveTelephone-based neuropsychological assessment (TeleNP) has been shown to be a valid alternative to in-person or video-based assessment. However, there is limited information regarding patients' satisfaction with TeleNP. This report presents satisfaction survey data from a diverse, clinical sample who received TeleNP during the coronavirus disease pandemic.MethodA total of 43 adult patients (30.2% Hispanic/Latinx, 32.6% Black), aged 24-75, who received TeleNP as part of routine clinical care participated in a postassessment satisfaction survey. Responses were analyzed qualitatively and via nonparametric comparisons based on demographic factors.ResultsGiven options of "Not Satisfied," "Somewhat Satisfied," "Satisfied," or "Very Satisfied," 97.7% of patients reported satisfaction with their visit as well as the visit length, and 80% felt the visit met their needs ("Good" + "Very Good"). There were no significant differences in responses based on age, race/ethnicity, sex, or education. Endorsed advantages of TeleNP included "Avoid potential exposure to illness" and "Flexibility/Convenience," and 20% reported difficulty communicating, concentrating, and/or connecting with their provider as potential disadvantages. Although 67.7% reported a preference for in-person visits, 83.7% expressed interest in another "virtual visit" (telephone or video conference) with their provider.ConclusionsTeleNP was well received by the sample and demonstrated good patient satisfaction. These results in conjunction with other research supporting the validity of TeleNP support consideration of this assessment modality for patients who might not otherwise have access to in-person or video conference-based neuropsychological services. Based on these findings, a greater focus on rapport building may be warranted when utilizing TeleNP to enhance patients' sense of connection to their provider.

Project description:The FER-R, Risk and Resource Assessment Form, is a multidimensional inventory of structured professional judgment that assesses criminogenic risks and resources for the design and management of individualized intervention plans with criminally sanctioned adolescents. The aim of this study was to examine the psychometric properties of the FER-R, reviewing its factorial structure to contribute evidence of convergent and discriminant construct validity in a sample of adolescents sentenced for crimes in Chile. For each domain (risks and resources) with its respective facets, a unidimensional bifactor structure (CFA-BF) was obtained, with adequate indices of fit that confirmed its construct validity, while the convergent validity was demonstrated with the YLS/CMI and the divergent validity with two MACI scales. The FER-R adds factorial validity to the evidence of the previously reported predictive validity, making it a robust inventory for the evaluation of young offenders, and a relevant tool to manage differentiated interventions in Chile, with a high potential for use in Latin America. The importance of finding a suitable balance in assessing risks and protective factors is discussed, in order to manage interventions adjusted to the needs of the adolescents to promote their criminal desistance.

Project description:Mitochondria maintain genome and translation machinery to synthesize a small subset of subunits of the oxidative phosphorylation system. To build up functional enzymes, these organellar gene products must assemble with imported subunits that are encoded in the nucleus. New findings on the early steps of cytochrome c oxidase assembly reveal how the mitochondrial translation of its core component, cytochrome c oxidase subunit 1 (Cox1), is directly coupled to the assembly of this respiratory complex.

Project description:PurposeThe present study aimed to construct and validate a Swedish translation (VVAS-S) of the Visual Vertigo Analogue Scale (VVAS).Materials and methodsThe original English VVAS was translated into Swedish by the two authors and back-translated by an independent professional translator. Pilot-tests were performed on two healthy participants and five patients suffering from Visually Induced Dizziness (VID). The translation was deemed understandable by all subjects. Twenty-one patients with VID were recruited to complete the VVAS-S, once in-lab and once at home after 2-3 weeks. Cronbach's alpha, inter-item consistency and internal consistency were calculated.ResultsTest-retest values were reliably strong across all items. Cronbach's alpha was 0.843, which is considered to represent very-high reliability. The corrected-item total-correlation was above 0.3 for all items, meaning they were appropriately associated with one-another. Fourteen out of 36 inter-item correlation interactions were within the 0.2-0.4 range.ConclusionsThe VVAS-S was found to be comparable to the original VVAS in terms of internal reliability. The translation was perceived as easy to implement by all participants and can be considered ready for clinical use in a Swedish-speaking setting. Item-specific correlations may be valuable for developing future vertigo questionnaires.Key messagesThe Swedish version of the Visual Vertigo Analogue Scale is a questionnaire suitable for evaluating visually induced dizziness in a Swedish population. This study found that the Swedish questionnaire was comparable to the original in terms of internal consistency. The Swedish Visual vertigo Analogue Scale can be found as an appendix to this article.

Project description:The aim of this study was to examine the psychometric properties of the Functional Assessment Cancer Therapy-Melanoma (FACT-M) questionnaire in the Serbian language. The FACT-M was translated into Serbian using the standard methodology after obtaining the licence from the Functional Assessment of Chronic Illness Therapy (FACIT) translation project team. This version of FACT-M was distributed to a cohort of consecutive patients with histologically confirmed high-risk skin melanoma treated at the tertiary referral center. To examine construct validity of the FACT-M in Serbian, we performed exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The FACT-General (FACT-G) did not fit the original 4-domain structure. Instead, we accepted a 7-domain structure which, aside from physical, emotional, social and functional well-being, had domains of 'friends' support', 'illness acceptance' and 'fear of death'. Melanoma scale (MS) and Melanoma surgery scale (MSS) did not fit the original one-dimensional structure. The MS was observed to have 4 domains: 'pain', 'skin problems', 'abdominal metastases' and 'other problems'. The MSS was observed to have 2 domains: 'having symptoms' and 'no symptoms'. It is suggested that the FACT-M questionnaire is analyzed using the newly extracted domains to examine quality of life of people with high-risk melanoma in Serbia.

Project description:Formal and semantic overlap across languages plays an important role in bilingual language processing systems. In the present study, Japanese (first language; L1)-English (second language; L2) bilinguals rated 193 Japanese-English word pairs, including cognates and noncognates, in terms of phonological and semantic similarity. We show that the degree of cross-linguistic overlap varies, such that words can be more or less "cognate," in terms of their phonological and semantic overlap. Bilinguals also translated these words in both directions (L1-L2 and L2-L1), providing a measure of translation equivalency. Notably, we reveal for the first time that Japanese-English cognates are "special," in the sense that they are usually translated using one English term (e.g., ??? /kooru/ is always translated as "call"), but the English word is translated into a greater variety of Japanese words. This difference in translation equivalency likely extends to other non-etymologically related, different-script languages in which cognates are all loanwords (e.g., Korean-English). Norming data were also collected for L1 age of acquisition, L1 concreteness, and L2 familiarity, because such information had been unavailable for the item set. Additional information on L1/L2 word frequency, L1/L2 number of senses, and L1/L2 word length and number of syllables is also provided. Finally, correlations and characteristics of the cognate and noncognate items are detailed, so as to provide a complete overview of the lexical and semantic characteristics of the stimuli. This creates a comprehensive bilingual data set for these different-script languages and should be of use in bilingual word recognition and spoken language research.

Project description:Rett syndrome (RTT) requires total caregiver attention and leads to potential difficulties throughout life. The Caregiver Burden Inventory, designed for Alzheimer disease, was modified to a RTT Caregiver Inventory Assessment (RTT CIA). Reliability and face, construct, and concurrent validity were assessed in caregivers of individuals with RTT. Chi square or Fisher's exact test for categorical variables and t tests or Wilcoxon two-sample tests for continuous variables were utilized. Survey completed by 198 caregivers; 70 caregivers completed follow-up assessment. Exploratory factor analysis revealed good agreement for physical burden, emotional burden, and social burden. Internal reliability was high (Cronbach's alpha 0.898). RTT CIA represents a reliable and valid measure, providing a needed metric of caregiver burden in this disorder.
