<p>In recent years, the development of entrepreneurial characteristics of students has come to the fore at all educational levels. This situation began to reflect on the curriculum. Thus, to the extent that teachers have entrepreneurial characteristics may be important. Especially ıt can be said that science teachers who will conduct the science curriculum which is a combination of different disciplines, to what extent they must have these features. It is a matter to be examined. For this concrete measurement tools are needed. The aim of this study was to develop "Entrepreneurship Scale Toward Student Teachers". This process was firstly created to item pool. Content validity of items has been achieved by resorting to expert opinions. Application was carried out in 2013-2014 academic year. Sample consists of 730 science student teachers. To form the factor structure of the scale consists of five subscales was used the exploratory and confirmatory factor analysis. Analysis showed that factor loads is found that values between .51 and 79, item-total-correlations is found that values between .35 and .68. the smallest eigenvalues has been found 3.0 and the smallest Variance ratios has been found % 41. And then five factor of the scale was confirmed by CFA. As a result of DFA was verified by considering Chi-square, RMSEA, CFI, NNFI, RMR, NFI, AGFI, GFI and SRMR fit index. the smallest Cronbach's alpha reliability coefficient is .77 and for test-retest reliability, the lowest correlation coefficient was found to be .66.</p><p> </p><p><strong>Özet</strong></p><p>Bu araştırmanın amacı “Öğretmen Adaylarına Yönelik Girişimcilik Ölçeği (ÖAYGÖ)”ni geliştirmektir.

Objectives: This study aims to adapt the Western Ontario Osteoarthritis of the Shoulder (WOOS) index specific to shoulder osteoarthritis into Turkish and to evaluate its validity and reliability. Patients and methods: The WOOS index was translated and culturally adapted into Turkish, systematically. It was applied to a total of 68 patients (17 males, 51 females; mean age: 61.5±8.7 years; range, 45 to 80 years) with osteoarthritis of the shoulder treated conservatively. The reliability of the scale was checked through internal consistency and test-retest methods. Internal consistency was analyzed with Cronbach alpha value. Test-retest reliability was assessed using an intraclass correlation coefficient (ICC) with 25 patients. The Western Ontario Rotator Cuff (WORC), the Shoulder Pain and Disability Index (SPADI), and the Society of American Shoulder and Elbow Surgeons Standardized Shoulder Assessment (ASES) scores were used to conduct concurrent validity. Results: The Cronbach alpha value of the scale was found to be excellent as 0.92 (p<0.001). The ICC value was also excellent as 0.97 (p<0.001). There was an excellent positive correlation with WORC (0.847; p<0.001) and a very good positive correlation with SPADI (0.788; p<0.001). It was also negatively very good to correlate with the ASES (-0.754; p<0.001). Additionally, subsections of WOOS had a good correlation with the corresponding subsections of WORC (0.779-0.664; p<0.001). Conclusion: The Turkish version of the WOOS index is a valid and reliable tool and is recommended for use in the assessment of patients with osteoarthritis of the shoulder.

This study aims to develop a scale that will measure the attitudes of 6th, 7thand 8th grade students towards scientific process in the scope of life sciences course. In the literature, many studies focus on developing scales of attitudes towards science and science course. This study differs from others by aiming to measure the attitudes towards using the scientific process steps rather than science itself. Items of the scale were prepared by considering expert opinions. The scale was administered to 321 students, from 6th, 7th and 8th grades in three different secondary schools. In accordance with the factor analysis performed, a 33 item, five-point likert-type scale was developed. The Kaiser-Meyer-Olkin (KMO), Barlett test, Cronbach alpha and test-retest reliability values of the scale was found as .94, 4386.47, .94 and .91 respectively.

Abstract. This study examines the psychometric properties of the IQCODE and its applicability in the Iranian elderly population. A group of 95 elderly patients with at least 4 years of formal education who fulfilled the criteria of DSM-IV-TR for dementia were examined by the MMSE and the AMTs. The Farsi version of the IQCODE was subsequently administered to their primary caregivers. Results showed a significant correlation ( p = .01) between the score of the questionnaire and the results of the MMSE ( r = −0.647) and AMTs ( r = −0.641). A high internal reliability of the questionnaire was confirmed by Cronbach’s alpha coefficient (α = 0.927) and test-retest reliability by correlation coefficient ( r = 0.81). This study found that the IQCODE has acceptable psychometric properties and can be used for evaluating the cognitive state in the elderly population of Iran.

Abstract. The Latin Square Task (LST) is a relational reasoning paradigm developed by Birney, Halford, and Andrews (2006) . Previous work has shown that the LST elicits typical reasoning complexity effects, such that increases in complexity are associated with decrements in task accuracy and increases in response times. Here we modified the LST for use in functional brain imaging experiments, in which presentation durations must be strictly controlled, and assessed its validity and reliability. Modifications included presenting the components within each trial serially, such that the reasoning and response periods were separated. In addition, the inspection time for each LST problem was constrained to five seconds. We replicated previous findings of higher error rates and slower response times with increasing relational complexity and observed relatively large effect sizes (η2p > 0.70, r > .50). Moreover, measures of internal consistency and test-retest reliability confirmed the stability of the LST within and across separate testing sessions. Interestingly, we found that limiting the inspection time for individual problems in the LST had little effect on accuracy relative to the unconstrained times used in previous work, a finding that is important for future brain imaging experiments aimed at investigating the neural correlates of relational reasoning.

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 &lt; 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.

While interpersonal skills in telehealth may positively impact clinical practice, patient engagement and outcomes, assessment strategies are lacking. We conducted a multi-stage iterative approach to develop and test validity and reliability of the Teaching Interpersonal Skills in Telehealth checklist (TIPS-TC). First, we identified observable communication behaviors from the literature. Second, we surveyed telehealth managers and researchers (N = 11) to rate appropriateness of potential checklist items. Level of agreement (35%–91%) and Kappa statistic (0.18–0.89) confirmed items to be retained and identified items to modify. Based on response patterns and comments, we reduced 44 items to 12 critical checklist behaviors. Third, student clinicians used the checklist with video telehealth consultations and provided feedback. Fourth, we conducted reliability testing with practitioners and administrators (N = 68) who completed the TIPS-TC for two versions of a telehealth scenario. Strong interrater reliability intraclass correlation coefficient (ICC) and test-retest reliability ICC (both p < .001), along with non-significant findings of order effects supported the checklist as an acceptable instrument to differentiate high skill from low skill telehealth sessions. The TIPS-TC offers an evidence-based approach to assessing interpersonal skills in telehealth to help evaluate clinician competence and tailor learning activities across disciplinary roles.

Abstract Objective The aim of this study was to investigate the validity and reliability of the Patient Dignity Inventory (PDI) in the Turkish society, which was developed to evaluate dignity-related distress in palliative care patients. Methods One hundred and twenty-seven adults with advanced cancer hospitalized in several clinics of two university hospitals were included in the study. The patients whose Palliative Performance Scale score was at least 40% were recruited to study. The data were collected with a patient demographic form, the Turkish version of Hospital Anxiety and Depression Scale (HADS-TR), and the Turkish version of the PDI (PDI-TR). The PDI-TR was finalized and back-translated after translating into Turkish and obtaining 10 expert opinions. Exploratory and confirmatory factor analysis, internal consistency, concurrent validity, and test–retest reliability analysis were performed. Results The Cronbach's α coefficient of PDI-TR was 0.94. Factor analysis resulted in a five-factor solution, and all items were loaded on factors. Factors were labeled as symptom distress, existential distress, self-confidence, dependency, and supportive care needs and accounted for 68.70% of the overall variance. The model's normed fit index, comparative fit index, and X2/SD were found between acceptable range (0.90, 0.93, and 2.64, respectively). A positive and strong correlation was found between subdimension scores of HADS-TR and the total score of PDI-TR (r = 0.70 for anxiety subdimension; r = 0.73 for depression subdimension). The test–retest reliability was conducted with 32 patients within the sample two weeks after the first application, and no significant difference was found between the two application scores as the result of paired-sample t-test (p > 0.05). An intraclass correlation coefficient of test–retest reliability was r = 0.855. Significance of results PDI-TR was found to be a valid and reliable tool in palliative care patients in Turkish society.

Abstract Background Physical inactivity is a global phenomenon in European welfare countries. Proper monitoring is essential to measure the physical activity level of the population. Methods In the Hungarian cohort of the European Physical Activity and Sport Monitoring System (EUPASMOS) project, our participants (N = 598) completed sociodemographic questions and the International Physical Activity Questionnaire – short form (IPAQ-SF) survey. The validity and reliability of the subjective measurement tool were examined, IPAQ-SF outcomes were contrasted against triaxial RM42 accelerometer wore for 7 consecutive days. Results The IPAQ-SF showed moderate internal consistency (Cronbach Alpha = 0.647). The concurrent validity of the IPAQ-SF to triaxial accelerometer indicated a significant weak-to-moderate correlation (R = 0.111–0.338, p = 0.042; p < 0.001). The test-retest reliability showed a significant correlation between two measurements (R = 0.788–0.981, p < 0.001). Conclusion The Hungarian version of the IPAQ-SF had excellent test-retest reliability, but low-to-fair concurrent validity for moderate and vigorous physical activity, walking and sitting time, as compared to the objective criterion measure among Hungarian adults.

The study was conducted to identify the most difficult topic in elementary teacher education first-year social science curriculum as perceived by the student-teachers by using survey research design. The study also investigated the underlying reasons responsible for the student-teachers' difficulties in learning different topics. 218 student-teachers were selected using convenience sampling technique from five District Institutes of Education and Training (DIET), in Tamil Nadu State (India) for the study. The instrument used for data collection was a checklist designed by the researchers to elicit information from the student-teachers. The data collected were analysed using frequencies and percentages. The results showed that the topic namely, 'Reading the Globe, Maps and Atlas' was perceived as the most difficult topic in social science curriculum. The results also showed that teaching the topic without using the maps, lack of previous knowledge about the maps, the existence of vague concepts, heavy content load, and lack of interest and motivation to learn map concepts were the main reasons responsible for the student-teachers' difficulties in learning the topic.
