Over the years, marketers have been cautioned repeatedly about the use of measuring instruments that do not demonstrate sufficient evidence of reliability and validity, particularly construct validity. The use of marketing instruments that do not demonstrate sufficient evidence of construct validity can lead to invalid results and erroneous conclusions. In short, construct validity is not just a “nice to have” in marketing research – it is at the heart of marketing decision-making.This study assesses the psychometric properties of a recently published instrument by Walsh and Beatty (2007) to measure the customer-based corporate reputation of a service firm, and illustrates how, by using an approach proposed by Steenkamp and Trijp (1991) to assess the uni-dimensionality of the underlying dimensions of a multi-dimensional construct, one can enhance the construct validity of such an instrument. The result is a shortened, 17-item instrument with superior psychometric properties compared to the longer 31-item instrument.

Neuropsychiatric Inventory

Neuropsychiatric symptoms (NPSs) cause a significant burden to individuals with memory disorders and their families. Insights into the clinical associations, neurobiology, and treatment of NPSs are largely dependent on informant questionnaires, such as the commonly used Neuropsychiatric Inventory (NPI). Like any scale, the utility of the NPI relies on its psychometric properties, but unlike many scales, the NPI faces unique challenges related to its skip-question and scoring formats.We examined and reviewed the psychometric properties of the NPI in a framework including psychometric properties pertinent for construct validation, and health-related outcome measurement in general. We found that aspects such as test-retest and inter-rater reliability are major strengths of the NPI in addition to its flexible and relatively quick administration. These properties are desired in clinical trials. However, it seems that the reported properties cover only some of the generally examined psychometric properties, representing perhaps necessary but not sufficient reliability and validity evidence for the NPI. There appear to be significant gaps in psychometric data, at least partially owing to small sample sizes in the studies that preclude more comprehensive analyses. Regarding construct validity, only one study examined structural validity with the NPI subquestions. Measurement error was not assessed in the reviewed studies. For future validation, we recommend using data from all subquestions, collecting larger samples, paying specific attention to construct validity and formulating hypotheses a priori. As the NPI is an outcome measure of interest in clinical trials, examining measurement error could be of practical importance.

Barriers To Physical Activity

Few studies have explored barriers to physical activity in parks and streets among children, adolescents, and their parents. The purpose of this article is to evaluate the psychometric properties of a new survey of barriers to physical activity in neighborhood parks and streets. Adolescents and parents of children and adolescents completed surveys twice. Two barrier subscales (environment and safety) emerged that applied to both locations and all participant groups. Results generally supported acceptable, internal consistency as well as construct validity, but test-retest reliabilities were lower than desired. These scales may be used to improve understanding of perceptions of barriers to physical activity in neighborhood parks and streets, but further development is needed.

Purpose The authors provide a review of the psychometric properties of 6 norm-referenced tests designed to measure children's phonological error patterns. Three aspects of the tests' psychometric adequacy were evaluated: the normative sample, reliability, and validity. Method The specific criteria used for determining the psychometric adequacy of these tests were based on current recommendations in the literature. Test manuals and response forms were reviewed for psychometric adequacy according to these criteria. Results The tests included in this review failed to exhibit many of the psychometric properties required of well-designed norm-referenced tests. Of particular concern was lack of adequate sample size, poor evidence of construct validity, and lack of information about diagnostic accuracy. Conclusions To ensure that clinicians have access to valid and reliable tests, test developers must make a greater effort to establish that the tests they design have adequate psychometric properties. The authors hope that this review will help clinicians and other professionals to be more aware of some of the limitations of using these tests to make educational decisions.

The Free Will and Determinism Plus (FAD+) is a widely-used questionnaire in research of belief in free will and has been translated into different languages. The present study aimed to assess the psychometric properties of the Chinese version of FAD+. We first translated and back-translated the FAD+, and then surveyed 1474 young adults, with 1333 valid data, in different sites in China. The first half of the data (n = 590) were used for items analysis, which resulted in the removal of 3 items. The rest of the data (n = 743) were used to assess the reliability, construct validity, and factor structure of the 24-item Chinese FAD+. Results revealed that the Chinese FAD+ are relatively reliable (α [.60 ~ .78], ω [.60 ~ .78], test-retest correlation [.54~ .59]) and valid (four-factor structure). Our results suggest that the 24-item FAD+ could be potentially useful for future studies that will use a similar population as ours.

Nursing presence has been conceptualized in the literature. However, no instrument has been developed to measure it. The purpose of this study was to develop a scale to measure patients’ perceptions of nursing presence and to examine its psychometric properties. A conceptual definition of nursing presence was operationalized and integrated into the 25-item Presence of Nursing Scale and tested on 330 hospitalized patients. Reliability and validity of the Presence of Nursing Scale were supported when tested with this sample. The study represents the first time the phenomenon of nursing presence has been measured.

If self-referent instruments about people’s health are to be useful in clinical and research settings, those instruments must be developed according to well-established processes and principles of measurement. We outline the main processes that should occur in the development of self-referent measuring instruments in general, with a focus, for illustrative purposes, on those intended to assess foot health. Requirements and issues concerning different forms of reliability and validity receive the most attention. In particular, problems associated with indices of test-retest reliability, inter-item homogeneity, and construct validity are identified and discussed. Practicalities concerning administration and scoring are also considered. A list of questions is provided for prospective users to assess the characteristics and quality of self-referent instruments.

Objectives. The aim of this study was to assess the psychometric properties of the Greek EORTC QLQ-C30 and QLQ-MY20 instruments.Method. A sample of myeloma patients (N=89) from two tertiary hospitals were surveyed with the QLQ-C30, QLQ-MY20 and various demographic and disease related questions. The previously validated Greek SF-36 instrument was used as a “gold standard” for health-related quality of life (HRQoL) comparisons. Hypothesized scale structure, internal consistency reliability (Cronbach's alpha) and various forms of construct validity (convergent, discriminative, concurrent and known-groups) were assessed.Results. Multitrait scaling confirmed scale structure of the QLQ-C30 and QLQ-MY20, with good item convergence (96% and 72%) and discrimination (78% and 58%) rates. Cronbach'sαwas >0.70 for all but one scale (cognitive functioning). Spearman's correlations between similar QLQ-C30 and SF-36 scales ranged between 0.35–0.80 (P<0.001). Expected interscale correlations and known-groups comparisons supported construct validity. QLQ-MY20 scales showed comparatively lower correlations with QLQ-C30 functional scales, and higher correlations with conceptually related symptom scales.Conclusions. The observed psychometric properties of the two instruments imply suitability for assessing myeloma HRQoL in Greece. Future studies should focus on generalizability of the results, as well as on specific issues such as longitudinal validity and responsiveness.

Abstract Background The levels of frailty are anticipated to increase as a result of population aging. A valid instrument is required to detect individuals at high risk of frailty. The present research aimed to assess feasibility, reliability, and construct validity of the Arabic version of Groningen Frailty Indicator (GFI) in urban and rural populations in South Lebanon. Methods During 2015, a cross-sectional study, which enrolled 390 community-dwelling individuals aged 65 years and above, was conducted in urban and rural areas in Nabatieh in South Lebanon. The survey included questions on sociodemographic and health-related characteristics, GFI, and Vulnerable Elders Survey-13 (VES-13). The translation and cultural adaptation of the GFI followed a standardized protocol. After that, the psychometric properties of the scale (i.e., feasibility, reliability, and validity) were evaluated. Results A total of 390 elderly filled out the questionnaire, of whom 51% were women and 70% lived in rural areas. 81.3% of elderly were identified as frail. The internal consistency of the GFI scale was high for all subscales (Cronbach’s alpha > 0.70), except the social scale (0.56). The GFI yielded statistically significant scores for subgroup analysis (known-groups validity) as higher levels of frailty were seen in older people, women, those with morbidities, and those reported poor financial status. The construct validity of the scale was supported by the significant correlation with the VES-13 (r = 0.73; p = 0.001), quality of life (r = − 0.22; p = 0.001), and self-reported health status (r = − 0.66; p = 0.001). Conclusion This study supports the feasibility, reliability, and validity of the GFI Arabic version as a screening tool for frailty among community-dwelling elderly in South Lebanon.

SummaryBackground: Due to the complexity of healthcare processes, the potential for Health Information Systems (HIS) to cause technology-induced errors is a growing concern. Health Information Technology (HIT) errors nearly always threaten good patient care and can lead to patient harm. Instruments to allow hospitals to proactively identify areas of Electronic Health Records (EHR) safety, to set priorities and to intervene before incidents occur are currently underdeveloped.Objectives: The aim was to design a Finnish questionnaire to measure EHR users’ perceptions of common EHR-related safety concerns in a specialized hospital district context through the lens of the theory of socio-technical dimensions. Moreover, the aim was to measure its reliability by assessing its internal consistency and validity, namely its content and construct validity.Methods: We constructed the instrument, based on the socio-technical theory and Sittig and Singh’s study findings, through a multi-stage process, and expert panels evaluated it to ensure its content validity. The final questionnaire consisted of eight error types to be assessed on a qualitative risk matrix scale. We used a cross-sectional design to test its psychometric properties. Application of the FIN-TIERA Questionnaire to a sample of 2864 clinicians in 2015 then served to evaluate the instrument’s reliability as well as its construct validity.Results: All eight multi-item scales showed high internal consistency (range α > 0.798-0.932 and CR 0.845-0.983). The average variance extracted (AVE) served to assess the confirmatory factor analysis (CFA). The results of the model fit with AGFI = .86, CFI = .898, RMSEA = .052, SRMR = .048 were deemed acceptable. For all factors, AVE yielded values > 0.5, which indicates adequate convergence and supports convergent validity. Discriminant validity was established for five out of a total of eight latent variables.Conclusions: FIN-TIERA is a new multi-dimensional instrument which may be a useful tool for assessing risk in EHR. Our testing shows its potential for use in-hospital settings: the involvement of EHR users demonstrated initial reliability and validity. Further research is recommended to assess the instrument’s psychometric properties.
