This study aims to produce a valid and reliable instrument in preparing students prior to class at university level of introductory Waves and Optics course. The instrument so called Pre-class Reading Task for Waves and Optics (PRT-WO) was used to probe students’ knowledge acquired through targeted reading activities. In practice, PRT-WO was given in a series before actual face-to-face class as a reading assignment. PRT-WO was content validated through expert review which was analyzed using the interrater reliability Cohen’s kappa. An item analysis was done to identify inappropriate items further evaluated using the reliability test of Kuder-Richardson 20 (KR20). The finding reveals that the value of kappa is 0.66 and the value of KR20 is 0.68, indicating that the developed instrument is valid and reliable.

Objective: To test the validity and reliability of the Chinese Geriatric Mental State Schedule (CGMS) in Taiwanese elders. Methods: The CGMS has gone through a standardized two-way translation, a pretest phase, and consensus focus group meetings in order to modify relevant culture-related terms of the original English version. The interrater reliability of the CGMS among eight psychiatrists was conducted after a training course was given to them. Diagnoses generated by the CGMS-AGECAT (Automated Geriatric Examination for Computer Assisted Taxonomy) were compared with psychiatric diagnoses according to the DSM-III-R criteria. The sample subjects were aged 65 and over and recruited from a community (n = 36) and an “old age home” (n = 56). Results: Four of the eight diagnostic categories generated by the CGMS-AGECAT had a generalized kappa value of 1.0, and the figures for the remaining four categories were acceptable: .8 for depressive neurosis, .6 for anxiety disorder, .5 for schizophrenia, and .5 for depressive psychosis (generalized kappa = .5). The overall agreement between the CGMS-AGECAT and independent psychiatric diagnosis (based on the DSM-III-R criteria) was satisfactory. Conclusion: The CGMS has been found to be a crossculturally valid and reliable instrument for use in Taiwan.

A 10-item instrument for the assessment of probable migration-related stressors was developed based on previous work (MIGSTR10) and interrater reliability was tested in a chart review study. The MIGSTR10 and nine nonspecific stressors of the DSM-IV Axis IV (DSMSTR9) were put into a questionnaire format with categorical and dimensional response options. Charts of 100 inpatients (50 Turkish migrants [MIG], 50 native German patients [CON]) with affective or anxiety disorder were reviewed by three independent raters and MIGSTR10, DSMSTR9, and Global Assessment of Functioning scale (GAF) scores were obtained. Interrater reliability indices (ICC) of items and sum scores were calculated. The prevalence of single migration-related stressors in MIG ranged from 15% to 100% (CON 0–92%). All items of the MIGSTR10 (ICC 0.58–0.92) and the DSMSTR9 (ICC 0.56–0.96) reached high to very high interrater agreement (p < .0005). The item analysis of the MIGSTR10 revealed sufficient internal consistency (Cronbach’s α = 0.68/0.69) and only one item (“family conflicts”) without substantial correlation with the remaining scale. Correlation analyses showed a significant overlap of dimensional MIGSTR10 scores (r² = 0.25; p < .01) and DSMSTR9 scores (r² = 9%; p < .05) with GAF scores in MIG indicating functional relevance. MIGSTR10 is considered a feasible, economic, and reliable instrument for the assessment of stressors potentially related to migration.

This study aimed to develop an instrument for measuring the attitudes that reflect the characteristics of the pandemic (Adult Pandemic Attitude Scale (A-PAS)) and verifying its validity and reliability. This study used a methodological research design and was conducted with a development step and an evaluation step. The development step included development of preliminary items, content validity, face validity, and preliminary investigation. The evaluation step included item analysis, construct validity, convergent validity, discriminant validity, criterion validity, factor naming, reliability, and completion of the final instrument. The A-PAS developed in this study consisted of a total of 20 items in five dimensions. The internal consistency of 20 items of the A-PAS, Cronbach’s α was 0.92 for 20 items, Cronbach’s α for each factor, a subscale of instrument, was 0.61~0.87 and Raykov’s p coefficient of each factor, which is a subscale of the tool, was found to be 0.60 to 0.88. Analysis of construct validity showed the results as follows: χ2 (p) = 134.05 (p < 0.001), RMSEA = 0.02, RMR = 0.02, GFI = 0.94, CFI = 0.99. The study findings suggest that the developed instrument can be utilized to measure the attitudes of adults toward pandemics, and reflect the reality of the pandemic situation. The outcomes can be used as valuable data for intervention, prevention activities, and policy preparation. The instrument will be applied in the event of a pandemic, such as COVID-19, and will be helpful in promoting the health of the people.

The Way

The focus of this research is how Sicilian state university mathematics professors faced the challenge of teaching via distance education during the first wave of the COVID-19 pandemic. Since the pandemic entered our lives suddenly, the professors found themselves having to lecture using an e-learning platform that they had never used before, and for which they could not receive training due to the health emergency. In addition to the emotional aspects related to the particular situation of the pandemic, there are two aspects to consider when teaching mathematics at a distance. The first is related to the fact that at university level, lecturers generally teach mathematics in a formal way, using many symbols and formulas that they are used to writing. The second aspect is that the way mathematics is taught is also related to the students to whom the teaching is addressed. In fact, not only online, but also in face-to-face modality, the teaching of mathematics to students on the mathematics degree course involves a different approach to lessons (as well as to the choice of topics to explain) than teaching mathematics in another degree course. In order to investigate how the Sicilian State university mathematics professors taught mathematics at distance, a questionnaire was prepared and administered one month after the beginning of the lockdown in Italy. Both quantitative and qualitative analyses were made, which allowed us to observe the way that university professors have adapted to the new teaching modality: they started to appropriate new artifacts (writing tablets, mathematical software, e-learning platform) to replicate their face-to-face teaching modality, mostly maintaining their blackboard teacher status. Their answers also reveal their beliefs related to teaching mathematics at university level, noting what has been an advantageous or disadvantageous for them in distance teaching.
