There is much literature on visual literacy across different fields of knowledge. Even so, generally there is a gap of literature that deals with measuring mathematical visual literacy skills. The objective of this paper is to produce empirical data on reliability and validity of mathematical visual literacy skills instrument. The development of items was based on the skills outlined Avgerinou’s VL Index (2007. The early stage in validating the instrument required researchers to seek face validity and content validity from panels of experts. Face validity was based on subjective judgements of the items. Meanwhile, content validity was determined by Content Validity Index (CVI) which is computed using Item-CVI (I-CVI) and Scale-CVI (S-CVI). Each mathematical visual literacy skills had accepted S-CVI values ranging from 0.86 to 1.00 but items with low I-CVI values were deleted. Next, construct validity and reliability was determined by using Exploratory Factor Analysis (EFA) and Cronbach’s alpha respectively. The instrument, consisting of 43 items was assessed on 428 pre-university students. Students’ responses were scored using analytical rubric developed by researchers. Using Principal Component Axis (PCA) and varimax rotation, EFA was carried out where 40 retaining items were extracted to 7 factors, representing each visual literacy skills. Kaiser-Meyer-Olkin (KMO) of 0.721, significant Bartlett’s Test of Sphericity (BTS), communalities anti images ranging between 0.308-0.721 and 0.503-0.835 respectively, 7 extracted factors explaining 53.685% of the total variance, factor loadings of ±0.520 and more, and overall Cronbach’s alphas of instrument recorded at 0.82, explained the complete validity and reliability of the instrument.

Abstract. Varimax rotated principal component scores (VRPCS) have previously been offered as a possible solution to the non-orthogonality of scores for the Big Five factors. However, few researchers have examined the reliability and validity of VRPCS. To address this gap, we use a lab study and a field study to investigate whether using VRPCS increase orthogonality, reliability, and criterion-related validity. Compared to the traditional unit-weighting scoring method, the use of VRPCS enhanced the reliability and discriminant validity of the Big Five factors, although there was little improvement in criterion-related validity. Results are discussed in terms of the benefit of using VRPCS instead of traditional unit-weighted sum scores.

Background/aimsTo develop, test and determine whether a surgical-competency assessment tool for simulated glaucoma surgery is valid.MethodsThe trabeculectomy ophthalmic simulated surgical competency assessment rubric (Sim-OSSCAR) was assessed for face and content validity with a large international group of expert eye surgeons. Cohorts of novice and competent surgeons were invited to perform anonymised simulation trabeculectomy surgery, which was marked using the Sim-OSSCAR in a masked fashion by a panel of four expert surgeons. Construct validity was assessed using a Wilcoxon rank-sum test. Krippendorff’s alpha was calculated for interobserver reliability.ResultsFor the Sim-OSSCAR for trabeculectomy, 58 of 67 surgeons (86.6%) either agreed or strongly agreed that the Sim-OSSCAR is an appropriate way to assess trainees’ surgical skill. Face validity was rated as 4.04 (out of 5.00). Fifty-seven of 71 surgeons (80.3%) either agreed or strongly agreed that the Sim-OSSCAR contents represented the surgical technique of surgical trabeculectomy. Content validity was rated as 4.00. Wilcoxon rank-sum test showed that competent surgeons perform better than novices (p=0.02). Interobserver reliability was rated >0.60 (Krippendorff’s alpha) in 19 of 20 steps of the Sim-OSSCAR.ConclusionThe Sim-OSSCAR for trabeculectomy, a newly developed and validated assessment tool for simulation glaucoma surgery, has validity and reliability. It has the potential to play a useful role in ophthalmic surgical education.

Background: Moral courage is required at all levels of nursing. However, there is a need for development of instruments to measure nurses’ moral courage. Objectives: The objective of this study is to develop a scale to measure nurses’ self-assessed moral courage, to evaluate the scale’s psychometric properties, and to briefly describe the current level of nurses’ self-assessed moral courage and associated socio-demographic factors. Research design: In this methodological study, non-experimental, cross-sectional exploratory design was applied. The data were collected using Nurses’ Moral Courage Scale and analysed statistically. Participants and research context: The data were collected from a convenience sample of 482 nurses from four different clinical fields in a major university hospital in Finland for the final testing of the scale. The pilot comprised a convenience sample of 129 nurses. Ethical considerations: The study followed good scientific inquiry guidelines. Ethical approval was obtained from the university ethics committee and permission to conduct the study from the participating hospital. Findings: Psychometric evaluation showed that the 4-sub-scale, 21-item Nurses’ Moral Courage Scale demonstrates good reliability and validity at its current state of development showing a good level of internal consistency for a new scale, the internal consistency values ranging from 0.73 to 0.82 for sub-scales and 0.93 for the total scale, thus well exceeding the recommended Cronbach’s alpha value of >0.7. Principal component analysis and confirmatory factor analysis supported the theoretical construct of Nurses’ Moral Courage Scale. Face validity and expert panel assessments markedly contributed to the relevance of items in establishing content validity. Discussion and conclusion: Nurses’ Moral Courage Scale provides a new generic instrument intended for measuring nurses’ self-assessed moral courage. Recognizing the importance of moral courage as a part of nurses’ moral competence and its assessment offers possibilities to develop interventions and educational programs for enhancement of moral courage. Research should focus on further validation measures of Nurses’ Moral Courage Scale in international contexts.

Purpose – This study aims to propose a new construct – prodigality and develop a measurement scale to support the construct. Design/methodology/approach – Combining the paradigms of Churchill, Malhotra and Birks, the item generation and content validity yielded the development of a modified scale. Three main steps in assessment of the scale: dimensional structure, reliability and validity led to the development of a prodigality scale. A total of 32 items were generated, through assessing Qur’anic verses that are related to Muslim consumption patterns linked to in Islam. Findings – In total, 23 items remained after content validity. A pre-test using exploratory factor analysis on the 23-item scale created a two-factor scale. According to extracted validity and reliability scores, prodigality scale was statistically supported. A pool of nine items is proposed for the eventual measurement of the prodigality. Research limitations/implications – The proposed measurement scale warrants further exploratory study. Future research should assess the validity across different Muslim geographies and Islamic schools of thought and practice. Originality/value – Prodigality is proposed as a new construct that focuses primarily on the Qur’an and seeks to achieve relevance and acceptance by both Sunni and Shia denominations. The measurement scale is believed to extend the existing body of literature and contribute new knowledge on Muslim consumption.

Background: A variety of interventions are available to support the caregivers of dementia patients. For the purposes of service planning, we developed an instrument to assess the needs of these caregivers and to determine whether needs are met. The reliability and validity of this new instrument was also investigated.Methods: The development of the Carers' Needs Assessment for Dementia (CNA-D), was based on in-depth interviews and a focus group. The combined inter-rater and test–retest reliability was investigated among 45 dementia caregivers. Correlations of the CNA-D with the Zarit Burden Inventory were used to analyze concurrent validity. Content validity was investigated by performing a separate survey among 40 caregivers and 40 professionals.Results: The CNA-D is a semi-structured research interview including 18 problem areas. For each problem area, the CNA-D offers several possible interventions. The relevance of the problem areas and the interventions (content validity) was confirmed by most of the study participants. Significant positive associations were found between the total score of the Zarit Burden Inventory and the number of problems and the number of unmet needs according to the CNA-D. The agreement between the interviewers was “excellent” (κ above 0.75) in 73.7% of the problem areas and in 69.9% of the interventions.Conclusions: The CNA-D is a valid and reliable instrument for comprehensively assessing the needs of dementia caregivers.

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.
