A Cross-National Analysis of the Psychometric Properties of the Geriatric Anxiety Inventory.

ABSTRACT:

Objectives

Assessing late-life anxiety using an instrument with sound psychometric properties including cross-cultural invariance is essential for cross-national aging research and clinical assessment. To date, no cross-national research studies have examined the psychometric properties of the frequently used Geriatric Anxiety Inventory (GAI) in depth.

Method

Using data from 3,731 older adults from 10 national samples (Australia, Brazil, Canada, The Netherlands, Norway, Portugal, Spain, Singapore, Thailand, and United States), this study used bifactor modeling to analyze the dimensionality of the GAI. We evaluated the "fitness" of individual items based on the explained common variance for each item across all nations. In addition, a multigroup confirmatory factor analysis was applied, testing for measurement invariance across the samples.

Results

Across samples, the presence of a strong G factor provides support that a general factor is of primary importance, rather than subfactors. That is, the data support a primarily unidimensional representation of the GAI, still acknowledging the presence of multidimensional factors. A GAI score in one of the countries would be directly comparable to a GAI score in any of the other countries tested, perhaps with the exception of Singapore.

Discussion

Although several items demonstrated relatively weak common variance with the general factor, the unidimensional structure remained strong even with these items retained. Thus, it is recommended that the GAI be administered using all items.

Project description:BackgroundDue to changes in Polish society resulting from a significant inflow of immigrants to Poland, the need to develop the cultural competences of various professional groups who have contact with immigrants in their work has increased. These groups should include healthcare professionals, especially because of the significant increase in the number of culturally diverse patients. Therefore, medical education in Poland has had to rapidly adapt to this novel situation. For instance, the teaching process should be now more focused on the development and evaluation of the cultural competences of prospective health care workers. However, there is still a lack of standardized, valid and reliable instruments to assess cross-cultural competences among healthcare professionals. The purpose of the present paper was to describe, for the first time, the translation, adaptation, and psychometric evaluation of the Polish version of the Cross-Cultural Competence Inventory.MethodsAcross two studies, we examined psychometric properties of the Cross-Cultural Competence Inventory (CCCI) such as reliability (i.e. internal consistency, test-retest reliability, factor structure) and validity (i.e. theoretical, criteria, convergent). In the first study, 408 participants (75% were healthcare professionals) completed the Polish version of the CCCI and the Positive/Negative Attitude Towards Culturally Divergent People Questionnaire. In the second study, 317 participants (97% were healthcare professionals) completed the CCCI twice, with an interval of at least 22 days. In addition, across two study sessions, participants completed questionnaires constructed to measure (a) cultural intelligence, (b) need for cognitive closure, (c) emphatic sensitiveness, (d) emotional intelligence, (e) self-esteem, (f) social desirability, and (g) personality. Finally, to additionally examine the theoretical validity, 36 professional cross-cultural competence trainers completed the CCCI during a one-session study.ResultsOur findings confirm the reliability and validity of the CCCI. More precisely, in study 1 we proved the theoretical validity and reliability (i.e. internal consistency) of the CCCI. While the assumed structure did not fit the data well, all items were significantly related to the general factor, thus providing strong support for the usage of the total score of the CCCI. In study 2, we additionally estimated the test-retest reliability and theoretical, criterion and convergent validity. Across two studies we were able to successfully confirm these psychometric properties. The reliability was satisfactory and ranged from .83 to .86. We also observed a high and significant positive correlation between CCCI and the Cultural Intelligence Scale, which measures a concept similar to the one measured by CCCI. In addition, a significant relationship between intercultural competences (CCCI) and other variables such as personality, empathic sensitivity, emotional intelligence, self-esteem (positive correlations) and the need for cognitive closure (mainly negative correlation) were demonstrated.ConclusionsThe obtained results support the usage of the CCCI questionnaire in scientific research, such as, for example, among healthcare professionals (nurses, doctors) and students of medical fields (nursing, medicine).

Project description:BackgroundPragmatic language assessment is a necessary component of evaluation in language impairments. Some procedures are applied to assess pragmatic abilities in childhood. Parent-report questionnaires are among the most useful instruments for evaluating pragmatics in real situations. This study aimed to translate and adapt the Language Use Inventory (LUI) into Persian and examine its psychometric properties.MethodIt was a methodological and cross-sectional study. We pursued the steps of translation and adaptation of this questionnaire into Persian according to a standard guideline. Then, 348 parents/caregivers of three groups of children consisting of typically developing (TD), late-talking children, and ones with autism spectrum disorders (ASD) 18-47-month-old Persian-speaking children completed the adapted version of the LUI. The participants were recruited into study by convenience sampling. Next, different psychometric properties including item analysis, validity (content, face, and construct), and reliability (test-retest and internal consistency) were investigated.ResultsTranslation, adaptation, and item analysis led to the deletion of 7 Items. Differential validity for age revealed the noticeably different performance among different age groups (p < 0.001). Also, Given the clinical validity, TD and ASD children performed differently in this measure(p < 0.001). In addition, the evidence of the discriminant validity was confirmed by a significant difference between TD and late-talking children (p < 0.001). Concurrent validity was also established by a moderate and positive value of the correlation between total scores of the LUI-Persian and Newsha developmental scale (r = 0.54, p = 0.01). Exploratory factor analysis (EFA) indicated that the Language Use Inventory-Persian had 2 factors of verbal and nonverbal use of language. Also, the evidence for the confirmatory factor analysis (CFA) was attained (all the values of factor load were higher than 0.40). The internal consistency (α = 0.99) and test-retest reliability (r = 0.97) proved adequate values.ConclusionsThe Language Use Inventory-Persian with 173 items revealed the acceptable psychometric attributes for assessing pragmatics in 18-47-month-old Persian-speaking children; however, for screening pragmatic impairments, it may need further studies on clinical populations with a larger sample size to see whether the LUI items are appropriate or possible changes in the items are required.
