The objective of the authors’ study was to develop a reliable and valid scale to assess reseller performance from the perspective of the supplier. To specify the domain of reseller performance, four different conceptualizations of organizational effectiveness were explored, leading to the identification of eight facets of reseller performance. Using data collected on the resellers of two different suppliers, the authors investigated the reliability and validity of three different types of scales—facet, composite, and global. Results indicate that two composite scales, a 5-item global scale, and seven 3-item facet scales have acceptable levels of reliability, construct validity, and generalizability.

Personality Inventories

Abstract. The need for efficient personality inventories has led to the wide use of short instruments. The corresponding items often contain multiple, potentially conflicting descriptors within one item. In Study 1 ( N = 198 university students), the reliability and validity of the TIPI (Ten-Item Personality Inventory) was compared with the reliability and validity of a modified TIPI based on items that rephrased each two-descriptor item into two single-descriptor items. In Study 2 ( N = 268 university students), we administered the BFI-10 (Big Five Inventory short version) and a similarly modified version of the BFI-10 without two-descriptor items. In both studies, reliability and construct validity values occasionally improved for separated multi-descriptor items. The inventories with multi-descriptor items showed shortcomings in some factors of the TIPI and the BFI-10. However, the other scales worked comparably well in the original and modified inventories. The limitations of short personality inventories with multi-descriptor items are discussed.

Class Play

Abstract. Social withdrawal in children is a risk factor for maladjustment. The Revised Class Play (RCP; Masten, Morison, & Pelligrini, 1985 ) has often been used to identify children’s behavioral difficulties with peers. However, in previous studies the sensitive-isolated scale of the RCP appeared to measure a mixture of different types of withdrawal, including withdrawal from peers and exclusion by peers. In the present study the original RCP was modified to more clearly distinguish withdrawal from the peer group from behavior associated with exclusion by peers. Two studies in Dutch samples of 8–13-year-old children were conducted to examine the reliability and validity of this modified Revised Class Play. Both studies revealed three scales: Sociability-Leadership, Aggressive-Disruptive, and a third factor labeled Anxious-Withdrawn. Anxious-Withdrawn primarily reflected social reticence. Stability of the scales after two years was high. High scores on the Anxious-Withdrawn scale were best predicted by teacher ratings of timid and anxious behavior and by negative self-perceptions of social competence. The results support the reliability and validity of the modified RCP in a Dutch sample.

AbstractConventional treatment modes like chemotherapy, thermal and radiations aimed at cancerous cells eradication are marked by destruction pointing the employment of nanomaterials as sustainable and auspicious materials for saving human lives. Cancer has been deemed as the second leading cause of death on a global scale. Nanomaterials employment in cancer treatment is based on the utilization of their inherent physicochemical characteristics in addition to their modification for using as nano-carriers and nano-vehicles eluted with anti-cancer drugs. Current work has reviewed the significant role of different types of nanomaterials in cancer therapeutics and diagnostics in a systematic way. Compilation of review has been done by analyzing voluminous investigations employing ERIC, MEDLINE, NHS Evidence and Web of Science databases. Search engines used were Google scholar, Jstore and PubMed. Current review is suggestive of the remarkable performance of nanomaterials making them candidates for cancer treatment for substitution of destructive treatment modes through investigation of their physicochemical characteristics, utilization outputs and long term impacts in patients.

Block Test

Commonly used rating scales and tests have been found lacking reliability and validity, for example in neurodegenerative diseases studies, owing to not making recourse to the inherent ordinality of human responses, nor acknowledging the separability of person ability and item difficulty parameters according to the well-known Rasch model. Here, we adopt an information theory approach, particularly extending deployment of the classic Brillouin entropy expression when explaining the difficulty of recalling non-verbal sequences in memory tests (i.e., Corsi Block Test and Digit Span Test): a more ordered task, of less entropy, will generally be easier to perform. Construct specification equations (CSEs) as a part of a methodological development, with entropy-based variables dominating, are found experimentally to explain (r=R2 = 0.98) and predict the construct of task difficulty for short-term memory tests using data from the NeuroMET (n = 88) and Gothenburg MCI (n = 257) studies. We propose entropy-based equivalence criteria, whereby different tasks (in the form of items) from different tests can be combined, enabling new memory tests to be formed by choosing a bespoke selection of items, leading to more efficient testing, improved reliability (reduced uncertainties) and validity. This provides opportunities for more practical and accurate measurement in clinical practice, research and trials.

In China, researchers have translated and validated several scales to measure victimization behavior. The aim of the present study was to validate the Chinese version of the victimization subscale of the Revised Peer Experiences Questionnaire (RPEQ) among primary school students. Primary school students aged between 8 and 13 years old (n = 1048) were asked to complete the Chinese version of the victimization subscale of the RPEQ and related scales. We examined internal consistency and the factor structure using confirmatory factor analysis (CFA). Depression, peer relationship, and sleep scales were used to measure construct validity. The CFA results suggested that the four-factor model had a good model fit. The results indicated that internal reliability was good (Cronbach’s α = 0.83). Construct validity was mostly supported by scores on the Chinese version of the victimization subscale of the RPEQ that strongly and positively correlated with depression and negatively correlated with peer relationship and sleep quality. The present study indicated that the Chinese version of the victimization subscale of the RPEQ has adequate reliability and validity for measuring bullying problems among Chinese primary school students.

Purpose: To adapt and validate a survey instrument to assess the nutrition environment of grab-and-go establishments at a university campus. Methods: A version of the Nutrition Environment Measures Survey for grab-and-go establishments (NEMS-GG) was adapted from existing NEMS instruments and tested for reliability and validity through a cross-sectional assessment of the grab-and-go establishments at the University of Toronto. Product availability, price, and presence of nutrition information were evaluated. Cohen’s kappa coefficient and intra-class correlation coefficients (ICC) were assessed for inter-rater reliability, and construct validity was assessed using the known-groups comparison method (via store scores). Results: Fifteen grab-and-go establishments were assessed. Inter-rater reliability was high with an almost perfect agreement for availability (mean κ = 0.995) and store scores (ICC = 0.999). The tool demonstrated good face and construct validity. About half of the venues carried fruit and vegetables (46.7% and 53.3%, respectively). Regular and healthier entrée items were generally the same price. Healthier grains were cheaper than regular options. Six establishments displayed nutrition information. Establishments operated by the university’s Food Services consistently scored the highest across all food premise types for nutrition signage, availability, and cost of healthier options. Conclusions: Health promotion strategies are needed to address availability and variety of healthier grab-and-go options in university settings.

Abstract This study investigated the association between the different types of plant-based diets and dyslipidemia in Korean adults using data from the nationally representative sample. Using the 2012-2016 Korea National Health and Nutrition Survey data, a total of 14,167 adults (≥19 years old) participated in this study. Dietary intake was assessed by a semi-quantitative food frequency questionnaire. Three different plant-based diet indices (overall plant-based diet index (PDI), healthful plant-based diet index (hPDI), unhealthful plant-based diet index (uPDI)), were calculated. Dyslipidemia and its components (hypertriglyceridemia, hypercholesterolemia, low high-density lipoprotein cholesterol (HDL-C), high low-density lipoprotein cholesterol (LDL-C), use of anti-hyperlipidemia agent) were measured. Multivariable logistic regression analysis was used to examine the associations between plant-based diet and dyslipidemia and individual lipid disorders. Totally, 47% of overall population had dyslipidemia. Individual in the highest quintile of uPDI had 22% greater odds of dyslipidemia (95% CI: 1·05, 1·41) and 48 % higher odds of hypertriglyceridemia (95% CI: 1·21, 1·81) and 16% higher odds of low HDL-C (OR: 1·16, 95% CI: 1·00, 1·35) than those in the lowest quintile of uPDI. PDI was associated with 16 % higher odds of low HDL-C and hPDI were associated with 25% lower odds of high LDL-C. However, Neither PDI nor hPDI was significantly associated with the prevalence of dyslipidemia. Greater adherence to unhealthful plant-based diets was associated with greater odds of the dyslipidemia and its components suggesting the importance of the quality of plant-based diet in South Korean adults for dyslipidemia prevention.

Behavioral Programming

A number of studies have identified “what works” in regard to the successful implementation of correctional programming over the past several decades. Few studies, however, have examined the complexities associated with programming in restrictive housing. Using data from a Midwestern department of corrections, we examined whether the provision of programming in restrictive housing achieved desired outcomes (e.g., reductions in inmate misconduct). The findings revealed the amount of time served in restrictive housing and confinement in different types of restrictive housing may influence estimations of a treatment effect. As a growing number of states seek to reform the use of restrictive housing, the proper implementation of cognitive-behavioral programming may increase institutional security and safety.

Purpose The purpose of this paper is to study more deeply the use of performance information (PI) in the context of the administrative-territorial reform, e.g. amalgamation in the local governments (LG) with an example of Estonian LGs. Design/methodology/approach The case study method is adopted, using data from publicly available documents and interviews with the politicians and officials at the five merger cases of Estonian LG units. The data are interpreted and analysed using attribution theory. Findings The results show that amalgamation patterns do have an influence on PI use – in particular, the authors see that PI is reported to be used more frequently in cases of voluntary mergers, which may be related to the different motivations to make attributions in cases of voluntary and compulsory mergers. Originality/value The study contributes to the debate on the importance and usefulness of different types of PI, as financial as well as non-financial information and for different information users in the light of LG reform in Estonia as being a Central and Eastern European country.

The purpose of this article is to provide a brief review of reliability and validity testing. These concepts are important to researchers who are choosing techniques and/or developing tools that will be applied and evaluated in diabetes education practice. Several types of reliability and validity testing are defined, and an easy-to-use check sheet is provided for research purposes. Following testing for the basic aspects of reliability and validity such as face and construct validity, a tool may be appropriate for use in practice settings. Those conducting comprehensive outcomes evaluations, however, may desire additional validation such as testing for external validity. Diabetes educators can and should incorporate rigorous testing for these important aspects when conducting assessments of techniques and tools relating to diabetes self-management training.
