Construct validity and internal consistency of the modified Persian version of the STarT Back Screening Tool

The Exercise Dependence Scale-Revised (EDS-R) has been suggested as screening tool for exercise dependence (ED), however, a validated Chinese version of this instrument is currently lacking. To this end, the present study translated and evaluated the psychometric properties of a Chinese version of the scale. Following a forward-backward translation of the EDS-R, the Chinese version (EDS-C) as well as validated scales assessing associated constructs were administered to a large sample of habitual exercisers (N=1447, 52.4% male) in universities and communities. Confirmatory Factor Analysis (CFA) was employed and invariance test across gender was carried out. Additionally, internal consistency and test-retest reliability were determined. Furthermore, construct validity was tested by investigating associations of ED with exercise variables and related constructs. We observed that the EDS-C confirmed the original seven-factor structure (TLI = .94, CFI = .95, RMSEA = .068, SRMR = .032) and showed invariance across genders. Moreover, we observed good internal consistency, with Cronbach alpha ranging from 0.73 to 0.93 for sub-scales and a moderate test-retest reliability (r: 0.45-0.82). The construct validity was additionally supported given that higher levels in EDS-C associated with a higher frequency of exercise and higher levels of eating disorder symptoms, body image inflexibility and generalized anxiety symptoms. In summary, EDS-C is a reliable and valid screening tool for ED in Chinese universities as well as communities.

Background: The Comprehensive Lower limb Amputee Socket Survey (CLASS) is a self-reported measure developed to assess prosthetic socket fit in individuals with lower limb amputation. Objective: To assess the reliability and validity of the Persian version of the CLASS. Study Design: Cross-sectional and repeated-measures. Methods: We evaluated the translation and back translation of the CLASS and made the required changes according to expert committee feedback. Then, we recruited 124 participants with unilateral lower limb amputation (89.5% men). Internal consistency was analyzed with Cronbach’s alpha and test–retest reliability using intra-class correlation coefficients. Convergent construct validity was assessed by comparing the CLASS scores with the Persian version of the Trinity Amputation and Prosthesis Experience Scales (TAPES) scores. In addition, known groups construct validity was assessed by comparing CLASS scores between groups with different causes and levels of amputation. Results: Cronbach’s alpha coefficient represented a very good internal consistency for all domains of the Persian CLASS (ranged from 0.86 to 0.92). The intra-class correlation coefficient for test–retest reliability for the Persian CLASS was good to excellent (ranged from 0.73 to 0.97). There was a significant correlation between the subscales of the Persian CLASS and satisfaction subscales of the Persian TAPES ( p < 0.001). There was no significant difference between the Persian CLASS scores by cause or level of amputation. Conclusion: The Persian CLASS is a reliable and valid measure for evaluating prosthetic socket fit.

Introduction: The Neck Bournemouth Questionnaire (NBQ) is being used widely in various countries. This study evaluated the validity and reliability of the Persian version of NBQ. Methods: This methodological study investigated 170 patients with chronic neck pain (NP). The psychometric properties of NBQ were evaluated in two stages. First, the standard scale was translated based on Guillemin’s guidelines for cross-cultural adaption and face validity tested in a pilot group (N=25). Second, it was conducted on a sample of 170 diverse chronic pain patients. Construct validity was determined with convergent validity by short-form McGill pain questionnaire. Then, the reliability was confirmed using Cronbach’s alpha and the intraclass correlation coefficient. Results: The instrument demonstrated a good face validity and the participants made minor changes. A slight change was applied on content validity. In construct validity, Pearson’s correlation coefficient was 0.85, which was statistically significant and showed strong correlation. A Cronbach’s alpha of 0.87 was obtained. This confirmed the remarkable internal consistency and stability (0.92). Conclusion: The Persian version of NBQ showed a good internal consistency and reliability and it could be considered as a valuable tool for assessing patients with cervical pain in Iranian population.

Community Dwelling Older Adults

Evidence suggests that community dwelling older adults (CDOA) are at risk for dysphagia (swallowing difficulties). Dysphagia is often unidentified until related morbidities like under nutrition or pneumonia occur. These cases of unidentified dysphagia, prior to any clinical intervention, may be termed ‘pre-clinical dysphagia’. Identifying pre-clinical dysphagia is challenged by the lack of validated tools appropriate for CDOA. This study addresses preliminary development of a novel patient reported outcome (PRO) screening tool for pre-clinical dysphagia. Initially, 34 questions were developed from literature review and expert opinion. Following pilot testing (n = 53), the questionnaire was revised and tested on 335 additional CDOA. Face validity, content validity, item analysis, reliability (internal consistency), and construct validity (exploratory factor analysis) measures were completed. Psychometric validation resulted in a 17-question PRO tool. Construct analysis identified a three-factor model that explained 67.345% of the variance. Emergent factors represented swallowing effort, physical function, and cognitive function. The results revealed strong construct validity and internal consistency (Cronbach’s α = 0.90). A novel, simple PRO incorporating multiple function domains associated with aging demonstrated strong preliminary psychometric properties. This tool is more comprehensive and aging-focused than existing dysphagia screening tools. Inclusion of multiple domains may be key in early identification of pre-clinical dysphagia.

Abstract Background: The current pandemic has classified older people into the most vulnerable category. Prior to the pandemic, they led active social lives, but are now cautioned to adopt more precautionary and preventive behaviors. Older people are advised to change their lifestyle given the challenges and expectations regarding aging. Therefore, the present study is designed to assess the construct validity and reliability of the Persian version of the 12-Item Expectations Regarding Aging Survey among older adult Iranian population during COVID-19 pandemic.Methods: The Persian version of this scale was developed using translation and revision in current study. The construct validity was assessed through Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). Also, the reliability was assessed through through its internal consistency (Cronbach’s alpha and McDonald’s omega), composite reliability (CR), and maximal reliability (MaxR). The data compiled online was based on a sample of 400 older adults aged above 65 years. Results: The results of the study indicate that the Persian version of this scale comprises three factors with 11 items (Factor 1: Physical Health; Factor 2: Mental Health; Factor 3: Cognitive Function) that explaining 65.764% of the total variance. The CFA results, after reviewing the model modification indices, shows the revised three factors model fits the data well with excellent internal consistency and reliability. Conclusion: The finding indicates that the Persian Version of ERA is reliable and valid. It can be used for aging, educational, and clinic research, to develop and evaluate on suitable intervention to enhance the quality of life among Iranian aging population.

ABSTRACTBackground:The Visual Cognitive Assessment Test (VCAT) is a language-neutral cognitive screening tool designed for use in culturally diverse populations without the need for translations or adaptations. While it has been established to be language-neutral, the VCAT’s construct validity has not been investigated.Methods:471 participants were recruited, comprising 233 healthy comparisons, 117 mild cognitive impairment (MCI), and 121 mild Alzheimer’s disease (AD) patients. VCAT and domain-specific neuropsychological tests were administered in the same sitting. Construct validity was assessed by analyzing domain-specific associations between the VCAT and well-established cognitive assessments. Reliability (internal consistency) was measured by Cronbach’s alpha. Diagnostic ability (area under the curve) and recommended cutoffs were determined by receiver operating characteristic (ROC) analysis.Results:The VCAT and its subdomains demonstrated good construct validity in terms of both convergent and divergent validity and good internal consistency (α = .74). ROC analysis found that the VCAT was on par with the Mini Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) at distinguishing between healthy comparisons, MCI, and mild AD. Consistent with previous studies, VCAT scores were not affected by language of administration or ethnicity in our cohort. Findings suggest the following cutoffs: Dementia 0–19, MCI 20–24, Normal 25–30.Conclusion:This study established the construct validity of the VCAT, which is vital to ensure its subdomains effectively measure the cognitive processes they were designed to. The VCAT is capable of detecting early cognitive impairments and allows for meaningful cross-cultural comparisons, especially useful for international collaborations and clinical trials, and for clinical use in diverse multiethnic populations.

Background: There are presently no validated scales to adequately measure the stigma of suicide in the community. The Stigma of Suicide Scale (SOSS) is a new scale containing 58 descriptors of a “typical” person who completes suicide. Aims: To validate the SOSS as a tool for assessing stigma toward suicide, to examine the scale’s factor structure, and to assess correlates of stigmatizing attitudes. Method: In March 2010, 676 staff and students at the Australian National University completed the scale in an online survey. The construct validity of the SOSS was assessed by comparing its factors with factors extracted from the Suicide Opinion Questionnaire (SOQ). Results: Three factors were identified: stigma, isolation/depression, and glorification/normalization. Each factor had high internal consistency and strong concurrent validity with the Suicide Opinion Questionnaire. More than 25% of respondents agreed that people who suicided were “weak,” “reckless,” or “selfish.” Respondents who were female, who had a psychology degree, or who spoke only English at home were less stigmatizing. A 16-item version of the scale also demonstrated robust psychometric properties. Conclusions: The SOSS is the first attitudes scale designed to directly measure the stigma of suicide in the community. Results suggest that psychoeducation may successfully reduce stigma.

Objective: The Colorado Cognitive Assessment (CoCA) was designed to improve upon existing screening tests in a number of ways, including enhanced psychometric properties and minimization of bias across diverse groups. This paper describes the initial validation study of the CoCA, which seeks to describe the test; demonstrate its construct validity; measurement invariance to age, education, sex, and mood symptoms; and compare it to the Montreal Cognitive Assessment (MoCA). Method: Participants included 151 older adults (MAge = 71.21, SD = 8.05) who were administered the CoCA, MoCA, Judgment test from the Neuropsychological Assessment Battery (NAB), 15-item version of the Geriatric Depression Scale (GDS-15), and 10-item version of the Geriatric Anxiety Scale (GAS-10). Results: A single factor confirmatory factor analysis model of the CoCA fit the data well, CFI = 0.955; RMSEA = 0.033. The CoCA’s internal consistency reliability was .84, compared to .74 for the MoCA. The CoCA had stronger disattenuated correlations with the MoCA (r = .79) and NAB Judgment (r = .47) and weaker correlations with the GDS-15 (r = -.36) and GAS-10 (r = -.15), supporting its construct validity. Finally, when analyzed using multiple indicators, multiple causes (MIMIC) modeling, the CoCA showed no evidence of measurement non-invariance, unlike the MoCA. Conclusions: These results provide initial evidence to suggest that the CoCA is a valid cognitive screening tool that offers numerous advantages over the MoCA, including superior psychometric properties and measurement non-invariance. Additional validation and normative studies are warranted.

Abstract Background The objective of this study was to verify the reliability, discriminatory power and construct validity of the Kidscreen-27 questionnaire in Brazilian adolescents. Methods Adolescents that participated of the pilot study (210 adolescents; 52.9% boys; 13.7 years old) and of the baseline (816 participants; 52.7% girls; 13.1 years old) of the Movimente Project in 2016/2017 composed the sample of the present study. This project was carried out in six public schools in the city of Florianópolis, Santa Catarina, Brazil. Test–retest reproducibility was assessed by the intraclass correlation coefficient and Gwet coefficient; internal consistency through McDonald's Omega; Hankins' Delta G coefficient verified the scale's discriminatory power and; confirmatory factor analysis to assess construct validity. Results Reproducibility values ranged from 0.71 to 0.78 for the dimensions (ICC), and ranged from 0.60 to 0.83 for the items (Gwet). McDonald's Ômega (0.82–0.91) for internal consistency measures. Discriminatory power ranging from 0.94 for the dimension Social Support and Friends to 0.98 for Psychological Well-Being. The factorial loads were > 0.40, except for item 19 (0.36). The fit quality indicators of the model were adequate (X2[df] = 1022.89 [311], p < 0.001; RMSEA = 0.053 (0.049–0.087); CFI = 0.988; TLI = 0.987), confirming the five-factor structure originally proposed. Conclusions The Brazilian-version Kidscreen-27 achieved good levels of reproducibility, internal consistency, discriminatory power and construct validity. Its use is adequate to measure the health-related quality of life of adolescents in the Brazilian context.
