BACKGROUND: Given the increased rate of divorce, it is important to analyse the characteristics of divorce applicants. The theory of planned behaviour (TPB) can provide a suitable framework to predict, explain, and/or change the behaviours. In Iran, no instrument can be found, based on health education models, to investigate divorce petition filing as a behaviour.AIM: This study was conducted to design a questionnaire on withdrawal of divorce petition based on the TPB and estimate its validity and reliability.MATERIAL AND METHODS: A qualitative study was conducted in 27 participants involved in the divorce process using directed content analysis. The face and content validity of 58 items, drawn from the qualitative study, were evaluated by 10 experts. The reliability was estimated using Cronbach’s alpha coefficient. The SPSS version 16 was used to analyse data.RESULTS: Estimates of the face and content validity (quantitative and qualitative), revealed that of the 58 items, 48 were valid based on four of the constructs of the TPB. Cronbach’s alpha coefficient was also derived greater than 0.6.CONCLUSION: The designed questionnaire, whose validity and reliability was confirmed in this study, can be used in similar studies. However, the social and cultural differences and their related effects should be considered.

Students are more likely to be successful in topics they are interested in than others. This study aims to develop an Acid–Base Interest Scale (ABIS) and subsequently evaluate the interest of pre-service science teachers in acids–bases according to gender, years at the university, type of high school the pre-service science teachers attended, and their relative success in the module General Chemistry II. Upon careful consideration of validity and reliability for the development of the ABIS, data were collected from 453 pre-service science teachers. The five-point Likert-type ABIS consisted of 26 items and entailed three factors (“Individual Interest”, “Interest in Theoretical Information”, and “Interest related to Daily Life”). Cronbach's alpha coefficient representing the reliability of the ABIS was 0.894. Once the reliability of the ABIS was ascertained, it was administered to 982 pre-service science teachers in eight public universities in Turkey. Of the potential determinants evaluated, gender and years at the university were found to be statistically significant, whereas the type of high school the pre-service science teachers attended and the grade achieved in module General Chemistry II failed to be statistically significant.

We present the Homeostasis Concept Inventory (HCI), a 20-item multiple-choice instrument that assesses how well undergraduates understand this critical physiological concept. We used an iterative process to develop a set of questions based on elements in the Homeostasis Concept Framework. This process involved faculty experts and undergraduate students from associate’s colleges, primarily undergraduate institutions, regional and research-intensive universities, and professional schools. Statistical results provided strong evidence for the validity and reliability of the HCI. We found that graduate students performed better than undergraduates, biology majors performed better than nonmajors, and students performed better after receiving instruction about homeostasis. We used differential item analysis to assess whether students from different genders, races/ethnicities, and English language status performed differently on individual items of the HCI. We found no evidence of differential item functioning, suggesting that the items do not incorporate cultural or gender biases that would impact students’ performance on the test. Instructors can use the HCI to guide their teaching and student learning of homeostasis, a core concept of physiology.

Function Assessment

Objective: Cerebral Palsy is one of the most common neurodevelopmental disorders in children. Due to the increase in the number of students with Cerebral Palsy (CP) entering ordinary schools and facing problems with independent functioning, there is a need for a valid and comprehensive assessment tool for their successful entry as well as providing a proper treatment plan. The School Function Assessment (SFA), by measuring many school-related functional skills, can identify the strengths and weaknesses affecting the students’ independence and participation in school assignments. It has 320 items and three main parts of participation, task support, and activity performance. The test score can be reported in general or based on each part, separately. The purpose of this study is to examine the validity and reliability of the Persian version of the SFA in children with CP. Materials & Methods: This is a cross-sectional study with methodological design. The study population consists of all children with CP aged 7-12 years in Tehran. Of these, 120 were selected from exceptional public school using a convenience sampling method. The inclusion criteria were: CP diagnosed by a neurologist, age between 7 and 12 years, no other disabilities (e.g. deafness or blindness), and the willingness of children’s parents to participate in the study. A demographic form and the Persian SFA were used for data collection through interview. In order to measure the content validity, Content Validity Index (CVI) and Content Validity Ratio (CVR) were calculated according to the standard protocol of International Quality of Life Assessment. In this regard, 8 experts in the field of pediatrics completed the Persian SFA. To determine the test-retest reliability, the questionnaire was completed by the parents of children with a 4-week interval. The internal consistency and test-retest reliability were examined by using Cronbach’s alpha coefficient and Intra-class Correlation Coefficient (ICC), respectively. Data was analyzed in SPSS V. 22 software. Results: Participants were 64 boys and 56 girls with CP (mean age= 9.4 years). The distribution of CP was as follows: 10% hemiplegic CP, 27.5% diplegic CP, 5.8% monoplegic CP, and 56.7% quadriplegic CP. Eighty hundred-eight percent of respondents were the mothers of students. The CVR and CVI values were in a range of 0.7-1 and 0.87-1, respectively indicating an acceptable validity. All the items had acceptable content validity. The Cronbach’s alpha coefficient was obtained 0.95 for participation, 0.95-0.99 for task support, 0.83-0.99 for activity performance, and 0.92 in total. Moreover, the ICC value was reported 0.90 for participation; 0.84-0.91 for task support; 0.84-0.97 for activity performance; and 0.89 for the overall test. Conclusion: The Persian version of SFA has acceptable content validity and reliability (internal consistency and test-retest) for children with CP. Therefore, it can be applied as a research and clinical tool to assess the school-related performance of these children.

Objective: This study aimed to translate the Assessment of Interpersonal Problem-Solving Skills (AIPSS) into Persian and to evaluate the validity and reliability of the Persian version of AIPSS to use for adults with schizophrenia. Materials & Methods: In this methodological study, the translation process was performed according to the International Quality of Life Assessment (IQOLA) protocol. The face validity of the translated AIPSS was determined based on the opinions of experts and The Content Validity Index (CVI) and Content Validity Ratio (CVR) were also calculated for each item. The Persian version of the test was performed on 52 patients with schizophrenia disorders at Tehran’s Razi Mental Hospital; they were selected using a convenience sampling method. Cronbach’s alpha coefficient was used to evaluate internal consistency. Inter-rater reliability was determined by the Intraclass Correlation Coefficient (ICC). A retest was complete on 15 patients with 2 weeks interval and ICC was used to determine the test-retest reliability. Results: Face validity was confirmed by the experts’ opinions. The Content Validity Ratio (CVR) and the Content Validity Index (CVI) were equal to one for all scenes. Cronbach's alpha coefficient for all scales was ranged between 0.511 and 0.821. The ICC in all scales were more than 0.98 for inter-rater reliability. In calculating test-retest reliability, the ICC for all scales ranged 0.733-0.893. Conclusion: Results show that the Persian version of AIPSS has acceptable face validity, content validity, internal consistency, inter-rater reliability test-retest reliability. Therefore, this instrument can be used in clinical fields and research studies to assess the social skills of Iranian patients with schizophrenia.

Concept inventories (CIs) are valuable tools for educators that assess student achievement and identify misconceptions held by students. Results of student responses can be used to adjust or develop new instructional methods for a given topic. The regulation of gene expression in both prokaryotes and eukaryotes is an important concept in genetics and one that is particularly challenging for undergraduate students. As part of a larger study examining instructional methods related to gene regulation, the authors developed a 12-item CI assessing student knowledge of the lac operon. Using an established protocol, the authors wrote open-ended questions and conducted in-class testing with undergraduate microbiology and genetics students to discover common errors made by students about the lac operon and to determine aspects of item validity. Using these results, we constructed a 12-item multiple-choice lac operon CI called the Lac Operon Concept Inventory (LOCI), The LOCI was reviewed by two experts in the field for content validity. The LOCI underwent item analysis and was assessed for reliability with a sample of undergraduate genetics students (n = 115). The data obtained were found to be valid and reliable (coefficient alpha = 0.994) with adequate discriminatory power and item difficulty.

The validity and reliability of the Children's Group Embedded Figures Test was reported for students in Grade 2 by Cromack and Stone in 1980; however, a search of the literature indicates no evidence for internal consistency or item analysis. Hence the purpose of this study was to examine the item difficulty and item validity of the test with children in Grades 1 and 2. Confusion in the literature over development and use of this test was seemingly resolved through analysis of these descriptions and through an interview with the test developer. One early-appearing item was unreasonably difficult. Two or three other items were quite difficult and made little contribution to the total score. Caution is recommended, however, in any reordering or elimination of items based on these findings, given the limited number of subjects ( n = 84).
