Background: The objective of this study was to investigate the psychometric properties of the Threadgold Communication Tool (TCT). Method: Internal consistency reliability was measured using Cronbach's α coefficient and inter-item correlation. Test-retest was performed to examine the instrument's stability. Exploratory principal component analysis (PCA) with oblimin rotation was carried out to evaluate construct validity. Finally, the score on each item of the TCT was correlated with the person's Mini Mental State Examination (MMSE) and Barthel Index of activities of daily living scores. Results: A total of 51 persons participated, with a mean age of 86.7 (SD 6.6) years, of whom 46 were women with moderate-to-severe dementia [mean MMSE score 7.5 (SD 6.7)]. There were two measurement points 2 weeks apart. The results showed a satisfactory level for internal consistency and a high test-retest reliability (r = 0.76). The corrected item-total correlation ranged between 0.50 and 0.87, and a two-factor structure was revealed at the PCA. ‘Vocalizing' seemed to measure another aspect of communication and was the only item which was negatively loaded. Conclusion: Despite the low sample size in this study, the results revealed the TCT as a reliable and valid instrument, suitable for measuring communication among people with dementia. We suggest clarifying the understanding of ‘vocalizing' before considering removing it from the scale.

The purpose of this study was to translate the Nursing Stress Scale (NSS) into Chinese and test its reliability and validity among Chinese nurses in Taiwan. Potential participants were asked to self-administer a Chinese version of the NSS. The agreement estimation was used to determine the equivalence of the meaning between the Chinese and original English versions and was rated by five bilingual nurses as 92% accurate for the 34 items. The test-retest reliability for the NSS at 2 weeks was .71 (p = .022, n = 10). Internal consistency reliability and factor analysis were tested with 770 nurses from 65 inpatient units at a medical center in Taiwan. The internal consistency of the Chinese version of the NSS for an overall coefficient alpha is .91 for the total scale, and ranges from .67 to .79 for the subscales. The Chinese version of the NSS explains 53.77% of the variance in work stressors among Chinese nurses in Taiwan. Overall, the Chinese version of the NSS is internally consistent but may not be stable over 2 weeks. There was adequate evidence of the reliability and validity of the NSS-Chinese as an instrument appropriate to measure work stress among Chinese nurses. The translated NSS could be a useful tool for examining the frequency and major sources of stress experienced by Chinese nurses in hospital settings, and for the development of appropriate interventions for stress reduction.

BACKGROUND Health information is often communicated through the internet. It is vital for the end user to have a range of digital skills as well as understand the information to promote their health. There is a valid and reliable 8-item instrument, the Electronic Health Literacy Scale (eHEALS), that evaluates these skills. The number of Arabic-speaking people migrating to Sweden and to other parts of the world is increasing due to unstable military and political situations in their countries of origin. Poor health and limited health literacy have been described in this population in Sweden. Still, to our knowledge, an Arabic version of eHEALS has not been tested for validity or reliability. Thus, Arabic-speaking populations in Sweden cannot be included in studies measuring eHealth literacy, which does not support equal treatment in health care. OBJECTIVE The aim of this study was to translate and adapt the original English eHEALS version into Arabic and to evaluate its psychometric properties. METHODS The eHEALS was rigorously translated, adapted, and evaluated for content validity. We conducted prospective psychometric evaluation with natively Arabic-speaking participants living in Sweden. Construct validity, factor structure, internal consistency, and test-retest reliability were evaluated using Spearman correlation, principal component analysis, Cronbach α, and weighted quadratic Cohen κ, respectively. RESULTS The study population consisted of Arabic-speaking participants (n=298; age: mean 41.8 years, SD 10.5). Construct validity was supported with weak and moderate correlations. Principal component factor analysis revealed a one-factor structure. Internal consistency was high (Cronbach α=0.92); test-retest reliability was acceptable (weighted quadratic Cohen κ=0.76). Evaluation indicated that eHealth literacy threshold values should be dichotomized (limited and sufficient) rather than trichotomized (inadequate, problematic, and sufficient). CONCLUSIONS The Arabic version of eHEALS, a unidimensional scale that is valid and reliable for measuring eHealth literacy among natively Arabic-speaking people in Sweden, was found to be acceptable and feasible in a general population.

Abstract Valid and reliable measures are needed to better understand the relationship between physical activity and crime. This paper provides a comprehensive psychometric evaluation of measures developed in the Safe and Fit Environments (SAFE) Study to assess a conceptual framework. In addition to assessing the basic psychometric properties of each measure (e.g., variable distributions [item/scale level], internal consistency reliability), this study formally examined the measurement validity and invariance of measures across four age groups using confirmatory factor analysis. The sample (n=2,173) included 336 Adolescents (aged 12-17), 532 Young adults (aged 18-39), 838 Middle Adults, and 467 Older Adults (aged 66+). The psychometric evaluation of (sub)scales showed consistent factorial validity and internal consistency reliability across the majority of the measures and across the four age groups. Specifically, 14 of the 17 measures subjected to a test of factorial validity displayed statistically and practically significant factor loadings and internal consistency values in the overall sample and across the age groups. The pattern of correlations for each (sub)scale with other (sub)scales/indexes largely did not exhibit redundancy across measures. The findings expanded upon the test-retest reliability evaluation reported in Patch et al. (2019) and suggest these measures can be used in predictive models.

This article describes the psychometric evaluation of the Modified Reminiscence Functions Scale (MRFS). The 39-item MRFS was validated on a sample of 271 racially diverse older adults. Psychometric analysis included content validity, item analysis, principal component analysis with varimax rotation, test–retest reliability, and internal consistency reliability using Cronbach’s alpha. The model’s structure supports a seven-factor, 39-item scale. Test–retest and Cronbach’s alpha for the instrument were .82 and .94, respectively. The seven-factor scale: self-regard, death, bitterness, intimacy, teach–inform, boredom, and conversation accounted for 61% of variance. Evidence indicates the self-report Likert instrument is a reliable and valid measure of reminiscence functions. Cross-validation with other populations and further research is needed to identify other reminiscence dimensions–functions.

The purpose of this study was to create a valid and reliable instrument to evaluate theory-basedbeliefs towards physical activity among clergy members. Data were collected from 174 clergy that par-ticipated in a 15-item online and paper-based survey. Psychometric properties of the instrument includedconfirmatory factor analysis (construct validity), and cronbach’s alpha (internal consistency reliability).In addition, the stability (test-retest reliability) of each subscale was evaluated with a sub-sample of 30participants. Results show the instrument was both valid and reliable, and will be useful in future studiestargeting this population. Future implications are discussed.

The Impact

Purpose Nurses have been called to be leaders in the transformation of health care and to help improve health-care access for the nation’s most vulnerable populations. However, to lead health-care transformation, the profession of nurses must first see themselves as leaders. Unfortunately, nursing has been described as lacking cohesiveness and failing to communicate a consistent brand image. No empirically tested quantitative tools exist to measure the brand identity of nursing, making it difficult to assess where the profession stands in regard to the mantel of leadership. The purpose of this study was to develop empirically sound instruments which could measure nurses’ perceptions of their professional brand image. A total of three scales were developed and then tested: The Nursing Brand Image Scale, Nursing’s Current Brand Position Scale and Nursing’s Desired Brand Position Scale. Design/methodology/approach The factor structure and internal consistency reliability of each scale were examined following survey administration to a national sample of registered nurses. Principal component analyses were used to explore the factor structure of each scale. Item reduction was achieved through examination of the loading of items across the factors and the impact of the item on internal consistency reliability. Findings Respondents to the survey were nursing alumni who received a baccalaureate or master’s degree in nursing at a private, mid-western university, and nursing faculty affiliated with a private, collegiate network (n = 286). For all scales, principal component analysis showed no inter-item correlations >0.9 or <0.1. The Kaiser–Meyer–Olkin measure for sampling adequacy was high and Bartlett’s test of sphericity was significant (p < 0001). The internal consistency reliability of each of the three scales was good to excellent. Current brand position mean scores were highest for the factor “caring advocates for patients/public”, and lowest on “influential leaders”. The most desired brand position mean scores were highest and rated similarly for factors “influential leaders” and “patient-centered caregivers”. Originality/value This study provides strong preliminary evidence for the factor structure and internal consistency reliability for each of the three scales and represents an important first step toward quantitatively measuring the brand image of nursing. However, results suggest there is work to be done if nursing is to formulate and adopt a brand image that consistently reinforces their role as leaders. Further testing of the scales with other nursing populations, the general public and with larger sample sizes is recommended.

Recent reviews of accounting education research have called for continued assessment of learning style inventories in accounting contexts (Geiger and Boyle 1992; Rebele et al. 1998). This study presents a critical evaluation of the psychometric properties of the Canfield Learning Styles Inventory (LSI), proposed by Francis et al. (1995) as an instrument for possible use by accounting educators. The study administered two versions (standard and scrambled) to 531 accounting majors from eight universities, applying a test-retest strategy after a 4–5 week interval. The versions were examined for internal consistency reliability, test-retest reliability, classification stability, and construct validity. We found moderate internal consistency (item analyses scores weaker than those reported by Canfield [1988]) and a substantial amount of learner-type classification instability across the two administrations. In terms of construct validity, two-factor solutions were not consistent with those reported by Canfield (1988). Further, three-factor solutions also were not consistent with Canfield's three learning domains. Therefore, along with limited theoretical support and the lack of empirical justification, we find little support for the use of the Canfield LSI in accounting education research.

Men with HIV have highlighted the importance of understanding their fertility desires. However, most research has focused on women. We aimed (1) to develop a survey instrument to assess fertility desires and intentions among HIV-positive men and (2) to assess its face, content, and construct validity, as well as test–retest reliability and internal consistency. Principal component analysis was used for construct validity analysis in a sample of 60 men with HIV. The test–retest reliability and internal consistency were assessed using Spearman correlation and Cronbach α, respectively. The initial and the final version of the questionnaire consisted of 10 domains and 14 constructs. We found a one-component model for the 3 constructs analyzed and Cronbach α values were ≥.70. Test–retest statistic was stable with Spearman correlation >0.70. In conclusion, a reliable and valid questionnaire was developed for determining the fertility desires and intentions of men with HIV.

Convergent And Divergent Validity

In this article, following an assumption that individualism and collectivism are separate factors, we have further established that three central components of individualism can be distinguished. In the first part of the article we examined whether the three proposed components of individualism—autonomy, mature self‐responsibility, and uniqueness—can be distinguished from each other in one cultural context, Estonia. A new scale was developed to measure the three aspects of individualism which demonstrated both the reasonable internal‐consistency reliability as well as convergent and divergent validity with several other measures of individualism and collectivism and related constructs. In the second part of the article we studied whether individualism generalizes across specific contexts or domains of social relationships, namely, across relations with family and close others; friends and peers; state and nation. The results of the three‐mode principal component analysis showed that the individualistic tendencies of the respondents did not differ much while measured toward the three types of social relation.
