An Instrument to Measure the Attentional Demands of Community-Dwelling Elders

The capacity to direct attention (CDA) is a pivotal facet of cognitive functioning that allows people to focus on trains of thought, complex tasks, and the daily business of life. According to a theoretical framework of directed attentional fatigue (DAF) and restoration, excessive demand for attention depletes CDA, a condition called DAF. Attentional demands are factors such as feelings of loss and worries that require intense or prolonged use of CDA and thus can lead to DAF. The purposes of this study were to determine reliability and validity for an instrument to measure attentional demands, the Attentional Demands Survey (ADS). The ADS was administered to 197 (142 females, 50 males) community-dwelling elderly (ages 65-98 years, M = 77). A factor analysis revealed 4 factors/subscales consistent with theorized domains. Internal consistency for each subscale ranged from .87 to .90 and test-retest reliability was .91. The ADS can be used to explore the relationships among attentional demands, CDA, and interventions to support and restore attentional functioning for elders.

This study aimed to verify the factorial structure, internal consistency, test-retest reliability, and discriminant validity of the High-need Community-dwelling Older Adults Screening Scale (HCOASS). A 20-item HCOASS covering five domains was used with a systematic random sample of 818 community-dwelling older adults. After the analyses, the Exploratory Factor Analysis suggested a removal of two items, resulting in 5 domains with 18 items, and the Confirmatory Factor Analysis yielded satisfactory results with Goodness of Fit Index of .98. The HCOASS demonstrated acceptable internal consistency (Kuder-Richardson Formula 20 α = .75) and excellent test-retest reliability (0.94; 95% CI [0.91, 0.97]). The area under the Receiver Operating Characteristic (ROC) curve was 0.90 (95% CI [0.84, 0.95]) and the optimal cut-off score was 4/5. The HCOASS is a valid and reliable screening tool. It has the potential for consistent and efficient administration to be used by non-healthcare professionals in the community.

This study developed and evaluated the Nurse Codependency Questionnaire (NCQ) and generated initial estimates of the stability and internal consistency of responses for the questionnaire. An initial pool of 95 items, reflective of four domains of codependency, was generated from the codependency literature using a domain-referenced approach. Seven expert judges from the nursing and codependency fields calculated the content validity index (CVI) as > .80. Items were critiqued for relevance, clarity, and predicted direction of each item’s correlation with the total codependency score. A convenience sample of 547 male and female nurses from Texas was recruited from a variety of professional settings to test the NCQ. Evidence of reliability and validity was sought through the use of principal factor analysis (PFA) techniques and correlation analysis. The specific domains of “codependent caretaking” and “lack of voice” represented two of the four hypothesized domains that were supported by factor analysis. Data screening and item analysis resulted in a final sample of 24 items. Test-retest reliability was .90 and internal consistency reliability was .80 for the entire scale. Reliability estimates for the “codependent caretaking” and “lack of voice” scales were .65 and .59, respectively for test-retest; and .81 and .64, respectively for internal consistency. Known groups validity was supported by each of the factors’ ability to discriminate between binge and nonbinge eaters. The NCQ may be useful for identifying codependency within the nursing profession. Research is needed to determine the external factors that influence the overt expression of nurse codependency. Screening for nurse codependency may contribute to the health of the profession by providing a means for anticipatory guidance and early intervention.

Mental fog is a core symptom of fibromyalgia. Its definition and measurement are central to an understanding of fibromyalgia-related cognitive disability. The Mental Clutter Scale was designed to measure mental fogginess. In an exploratory factor analysis of two different samples ( n = 128 and n = 170), cognitive symptoms of fibromyalgia loaded on 2 dimensions: cognition and mental clarity. The mental clarity factor comprised 8 items with factor loadings greater than .60 and was named the Mental Clutter Scale. The factor stability of the new scale was good, internal consistency was .95, and test-retest reliability over a median of 5 days was .92. The 8-item scale is a quick measure of mental fog that provides clinicians with information about cognitive functioning in fibromyalgia.

Abstract Objective Shame contains external and internal aspects. However, a Japanese language scale for simultaneously assessing both aspects of shame has not been developed to date. This study aimed to standardize the Japanese version of the External and Internal Shame Scale (EISS-J). An online survey was conducted among university students (N = 203) at six universities in Japan (Study 1). A retest questionnaire was sent to the participants by email three weeks after the first survey (Study 2). Study 1 examined the internal consistency, factor structure, and criterion-related validity of the EISS-J, while Study 2 examined its test-retest reliability. Moreover, an additional study was conducted to examine the criterion-related validity of the scale. Results Study 1 demonstrated the high internal consistency of the EISS-J. Moreover, confirmatory factor analysis indicated a two-factor model: external and internal shame. However, exploratory factor analysis indicated a three-factor structure. Study 2 confirmed the test-retest reliability of the scale. Furthermore, both studies indicated correlations between the EISS-J and fear of compassion, anger, humiliation, depression, anxiety, and stress. In addition, the study established the criterion-related validity of the scale. These results confirmed adequate reliability and validity of the EISS-J.

Abstract Background Hemodialysis is considered a major therapeutic method for patients with chronic kidney disease. Pruritus is a common complaint of hemodialysis patients. The 5-D pruritus scale is amongst the most common tools to evaluate several dimensions of itch. Psychometric properties of the 5-D scale have not been evaluated in Persian speaking population with hemodialysis; hence, the objective of this study was to assess reliability and validity of the Persian version of the scale. Methods Ninety hemodialysis patients (men: 50, women: 40, mean age: 54.4 years) participated in this cross-sectional study. The final Persian version of 5-D scale was given to the participants. Tests Compared: One-third of the participants completed the scale twice within 3–7 days apart to evaluate test- retest reliability. Other psychometric properties including internal consistency, absolute reliability, convergent, discriminative and construct validity, floor/ceiling effects were also evaluated. Results The Persian 5-D scale has strong test-retest reliability (ICC= 0.98) and internal consistency (Cronbach’s alpha= 0.99). Standard error of measurement and minimal detectable change were 0.33 and 0.91, respectively. Regarding convergent validity, the scale had moderate correlation with numeric rating scale (r =0.67) and quality of life questionnaire related to itch (r = 0.59). Exploratory factor analysis revealed two factors within the scale. No floor or ceiling effect was found for the scale. Conclusion The Persian version of 5-D the itching scale is a brief instrument with acceptable reliability and validity. Therefore, the scale could be used by experts, nurses, and other health service providers to evaluate pruritus among Persian speaking hemodialysis patients.

Abstract Background Critical thinking disposition helps medical students and professionals overcome the effects of personal values and beliefs when exercising clinical judgment. The lack of effective instruments to measure critical thinking disposition in medical students has become an obstacle for training and evaluating students in undergraduate programs in China. The aim of this study was to evaluate the psychometric properties of the CTDA test. Methods A total of 278 students participated in this study and responded to the CTDA test. Cronbach’s α coefficient, internal consistency, test-retest reliability, floor effects and ceiling effects were measured to assess the reliability of the questionnaire. Construct validity of the pre-specified three-domain structure of the CTDA was evaluated by explanatory factor analysis (EFA) and confirmatory factor analysis (CFA). The convergent validity and discriminant validity were also analyzed. Results Cronbach’s alpha coefficient for the entire questionnaire was calculated to be 0.92, all of the domains showed acceptable internal consistency (0.81–0.86), and the test-retest reliability indicated acceptable intra-class correlation coefficients (ICCs) (0.93, p < 0.01). The EFA and the CFA demonstrated that the three-domain model fitted the data adequately. The test showed satisfactory convergent and discriminant validity. Conclusions The CTDA is a reliable and valid questionnaire to evaluate the disposition of medical students towards critical thinking in China and can reasonably be applied in critical thinking programs and medical education research.

Abstract Objectives To examine the validity and reliability of the Mandarin version of the Treatment Burden Questionnaire (TBQ) among stroke patients. Background Stroke patients need long-term management of symptoms and life situation, and treatment burden has recently emerged as a new concept that can influence the health outcomes during the rehabilitation process. Methods The convenience sampling method was used to recruit 187 cases of stroke patients in a tertiary grade hospital in Tianjin for a formal investigation. Item analysis, reliability and validity tests were carried out. The reliability test included internal consistency and test–retest reliability. And as well as content, structure and convergent validity were performed for the validity test. Results Of the 187 completed questionnaires, only 180 (96.3%) were suitable for analysis. According to the experts’ evaluation, the I-CVI of each item was from 0.833 to 1.000, and the S-CVI was 0.967. The exploratory factor analysis yielded three-factor components with a cumulative variation of 53.054%. Convergent validity was demonstrated using measures of Morisky’s Medication Adherence Scale 8 (r = –0.450, P < 0.01). All correlations between items and global scores ranged from 0.403 to 0.638. Internal consistency reliability and test–retest reliability were found to be acceptable, as indicated by a Cronbach’s α of 0.824 and an intraclass correlation coefficient of 0.846, respectively. Conclusions The Mandarin TBQ had acceptable validity and reliability. The use of TBQ in the assessment of treatment burden of stroke survivor may benefit health resources allocation and provide tailor therapeutic interventions to construct minimally disruptive care.

Introduction Several general hand functional assessment tools for Dupuytren’s disease have been reported, but none of the patient-reported-outcome measures specific to Dupuytren’s disease-associated disabilities are available in the Italian language. The purpose of this study was to culturally adapt the Unité Rhumatologique des Affections de la Main (URAM) into Italian (URAM-I) and determine its measurement properties. Methods Cross-cultural adaptation was performed according to the current guidelines. Construct validity (convergent and divergent validity) was measured by comparing the URAM-I with the Pain-Rated Wrist/Hand Evaluation (PRWHE-I), Short-Form 36 (SF-36-I) scale and finger range of motion, respectively. Factor analysis was used to investigate the URAM-I’s internal structure. Reliability was assessed by internal consistency (Cronbach’s alpha) and test-retest reliability by Intra-Class Correlation Coefficient (ICC). Results This study included 96 patients (males = 85%, age = 66.8 ± 9.3). Due to the cultural adaptation, we divided the original item #1 into two separate items, thus generating the URAM-I(10). Convergent validity analysis showed a strong positive (r = 0.67), significant (p < 0.01) Pearson’s correlation with the PRWHE-I. Divergent validity analysis showed a weak, negative (r < 0.3) and not significant correlation with the SF-36-I subscales, except for the physical pain subscale (r = −0.21, p < 0.05). Factor analysis revealed a 2-factor, 4-item solution that explained 76% of the total variance. The URAM-I(10) demonstrated high internal consistency (α = 0.94) and high test-retest reliability (ICC = 0.97). Conclusion The URAM-I(10) demonstrates moderate construct validity, high internal consistency and test-retest reliability, and showed a 2-factor internal structure. Its evaluative use can be suggested for the Italian Dupuytren’s population.

ObjectivesThe Ocular Surface Disease Index (OSDI) questionnaire is widely used to evaluate subjective symptoms of dry eye disease (DED) as a primary diagnostic criterion. This study aimed to develop a Japanese version of the OSDI (J-OSDI) and assess its reliability and validity.Design and settingHospital-based cross-sectional observational study.ParticipantsA total of 209 patients recruited from the Department of Ophthalmology at Juntendo University Hospital.MethodsWe translated and culturally adapted the OSDI into Japanese. The J-OSDI was then assessed for internal consistency, reliability and validity. We also evaluated the optimal cut-off value to suspect DED using an area under the receiver operating characteristic curve (AUC) analysis.Primary outcome measuresInternal consistency, test–retest reliability and discriminant validity of the J-OSDI as well as the optimal cut-off value to suspect DED.ResultsOf the participants, 152 had DED and 57 did not. The J-OSDI total score showed good internal consistency (Cronbach's alpha=0.884), test–retest reliability (interclass correlation coefficient=0.910) and discriminant validity by known-group comparisons (non-DED, 19.4±16.0; DED, 37.7±22.2; p<0.001). Factor validity was used to confirm three subscales within the J-OSDI according to the original version of the questionnaire. Concurrent validity was assessed by Pearson correlation analysis, and the J-OSDI total score showed a strong positive correlation with the Dry Eye-Related Quality-of-Life Score (γ=0.829). The optimal cut-off value of the J-OSDI total score was 36.3 (AUC=0.744).ConclusionsThe J-OSDI was developed and validated in terms of reliability and validity as an effective tool for DED assessment and monitoring in the Japanese population.
