Spiritual care is essential for the health and well-being of patients and their families, so nursing and midwifery students should have professional competency in this field.
Objectives
The present study aimed to translate the Spiritual Care Competency Self-Assessment Tool for nursing and midwifery students into Persian and evaluate its psychometric properties.
Methods
This study has a methodological study design.
Methods measures
The present study was conducted from July 4 to November 19, 2023, at the Faculty of Nursing and Midwifery in west of Iran. The tool was translated into Persian using the forward-backward translation method. The construct validity was examined using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) with a total of 536 nursing and midwifery students. The internal consistency was assessed using Cronbach’s alpha coefficient. Also, the reliability of the tool was evaluated using the test–retest method. SPSS version 26 and Lisrel version 8 software were used in this study.
Results
Face and content validity was confirmed quantitatively and qualitatively. The results of EFA and CFA confirmed the tool with 4 factors and 28 items. CFA results indicated a well-fitting model (comparative fit index [CFI] = .97, Non-Normed Fit Index (NNFI) = .92, goodness of fit index [GFI] = .91, root mean square error of approximation [RMSEA] = .05, Standardized Root Mean Square Residual (SRMR) = .046). Pearson’s correlation coefficient confirmed a significant relationship between items, subscales, and the main scale. Also, Cronbach’s alpha coefficient (.968) and test–retest (.867) confirmed the reliability of the Persian version of the tool.
Conclusion
The present study showed that the Persian version of the EPICC Spiritual Care, with 4 factors and 28 items, was suitable for validation and that its psychometric properties were acceptable according to COSMIN criteria. In general, the results showed that the Persian version of the EPICC Spiritual Care is a valid and reliable tool that students, preceptors, and educators can use in clinical settings as a practical way of discussing and evaluating spiritual care competency in Iran.
The main principles underpinning measurement for healthcare improvement are outlined in this Element. Although there is no single formula for achieving optimal measurement to support improvement, a fundamental principle is the importance of using multiple measures and approaches to gathering data. Using a single measure falls short in capturing the multifaceted aspects of care across diverse patient populations, as well as all the intended and unintended consequences of improvement interventions within various quality domains. Even within a single domain, improvement efforts can succeed in several ways and go wrong in others. Therefore, a family of measures is usually necessary. Clearly communicating a plausible theory outlining how an intervention will lead to desired outcomes informs decisions about the scope and types of measurement used. Improvement teams must tread carefully to avoid imposing undue burdens on patients, clinicians, or organisations. This title is also available as Open Access on Cambridge Core.
This study aims to validate the Palliative and Complex Chronic Pediatric Patients QoL Inventory (PACOPED QL), a new quality-of-life (QoL) assessment tool for pediatric palliative patients with complex chronic conditions. The goal is to create a comprehensive and inclusive instrument tailored to this unique population, addressing the gap in existing tools that do not meet these specific needs.
Methods
The validation process included a literature review and consultations with experts. A pilot study refined the items, followed by a cross-sectional study involving pediatric palliative patients and their caregivers. Statistical analyses, such as Cronbach’s alpha for internal consistency and exploratory factor analysis for structural validity, were utilized.
Results
The PACOPED QL, comprising 50 items across 8 domains and 6 subdomains, demonstrated strong reliability with Cronbach’s alpha and Guttman split-half reliability both exceeding .9. Validity assessments confirmed its suitability for children with complex illnesses. The tool was refined through expert consultations and pilot testing, reducing items from an initial 85 to a final 50, ensuring relevance and clarity.
Significance of results
The PACOPED QL shows strong reliability and validity in assessing QoL in pediatric palliative patients. Its comprehensive structure makes it a promising tool for clinical practice and research, addressing a critical need for a tailored assessment in this population. The instrument’s robust psychometric properties indicate its potential utility in improving the QoL assessment and care for children with life-threatening illnesses. Further studies are encouraged to confirm its effectiveness across various settings.
A recent debate on implicit measures of racial attitudes has focused on the relative roles of the person, the situation, and their interaction in determining the measurement outcomes. The chapter describes process models for assessing the roles of the situation and the person-situation interaction on the one hand and stable person-related components on the other hand in implicit measures. Latent state-trait models allow one to assess to what extent the measure is a reliable measure of the person and/or the situation and the person-situation interaction (Steyer, Geiser, & Fiege, 2012). Moreover, trait factor scores as well as situation-specific residual factor scores can be computed and related to third variables, thereby allowing one to assess to what extent the implicit measure is a valid measure of the person and/or the situation and the person-situation interaction. These methods are particularly helpful when combined with a process decomposition of implicit-measure data such as a diffusion-model analysis of the IAT (Klauer, Voss, Schmitz, & Teige-Mocigemba, 2007).
P. M. Bentler has shown that Rao's canonical factor analysis is in effect a psychometric analysis, leading to factors that are maximally assessible from the data. He contrasts this with Kaiser and Caffrey's alpha factor analysis that leads to factors that maximally represent the true factors in the content domain. Noting the problems associated with factors that may be highly assessible, but not very representative, or vice versa, Bentler suggests the need for a technique that would, insofar as possible, be optimal with respect to both criteria. Such a technique is presented here, and is shown to resolve into a traditional scaling method, which in turn acquires a richer psychometric interpretation.
Adequate measurement of psychological phenomena is a fundamental aspect of theory construction and validation. Forming composite scales from individual items has a long and honored tradition, although, for predictive purposes, the power of using individual items should be considered. We outline several fundamental steps in the scale construction process, including (1) choosing between prediction and explanation; (2) specifying the construct(s) to measure; (3) choosing items thought to measure these constructs; (4) administering the items; (5) examining the structure and properties of composites of items (scales); (6) forming, scoring, and examining the scales; and (7) validating the resulting scales.
This chapter focuses on experimental designs, in which one or more factors are randomly assigned and manipulated. The first topic is statistical power or the likelihood of obtaining a significant result, which depends on several aspects of design. Second, the chapter examines the factors (independent variables) in a design, including the selection of levels of a factor and their treatment as fixed or random, and then dependent variables, including the selection of items, stimuli, or other aspects of a measure. Finally, artifacts and confounds that can affect the validity of results are addressed, as well as special designs for studying mediation. A concluding section raises the possibility that traditional conceptualizations of design – generally focusing on a single study and on the question of whether a manipulation has an effect – may be inadequate in the current world where multiple-study research programs are the more meaningful unit of evidence, and mediational questions are often of primary interest.
The procedure for a preliminary ruling is central in the ‘complete system of remedies’ offered by the Union to its citizens. Since Article 263 TFEU grants only a very reduced standing to ‘non-privileged applicants’, Article 267 TFEU became the main gate for individuals to bring their claims against the EU before the European Court of Justice. Yet, claims for breaches of fundamental rights by the Union are not at all common in the procedure for a preliminary ruling. This chapter investigates the (real) use and (realistic) potential of Article 267 TFEU as a means for the protection of fundamental rights against breaches by the EU institutions. The chapter maps all instances in which individuals used the procedure for a preliminary ruling to bring a claim against the Union for breaches of their fundamental rights since the coming into force of the Treaty of Lisbon. Using this mapping exercise, the chapter identifies how individuals raise this type of claims in the procedure, discusses the accessibility of the procedure for individual applicants, and assesses the shortcomings of the procedure as a means to redress breaches of fundamental rights by the Union. It argues that these shortcomings have to do with the structure and design of the procedure itself.
Parrots are popular companion animals but show prevalent and at times severe welfare issues. Nonetheless, there are no scientific tools available to assess parrot welfare. The aim of this systematic review was to identify valid and feasible outcome measures that could be used as welfare indicators for companion parrots. From 1,848 peer-reviewed studies retrieved, 98 met our inclusion and exclusion criteria (e.g. experimental studies, captive parrots). For each outcome collected, validity was assessed based on the statistical significance reported by the authors, as other validity parameters were rarely provided for evaluation. Feasibility was assigned by considering the need for specific instruments, veterinary-level expertise or handling the parrot. A total of 1,512 outcomes were evaluated, of which 572 had a significant P-value and were considered feasible. These included changes in behaviour (e.g. activity level, social interactions, exploration), body measurements (e.g. body weight, plumage condition) and abnormal behaviours, amongst others. Many physical and physiological parameters were identified that either require experimental validation, or veterinary-level skills and expertise, limiting their potential use by parrot owners themselves. Moreover, a high risk of bias undermined the internal validity of these outcomes, while a strong taxonomic bias, a predominance of studies on parrots in laboratories, and an underrepresentation of companion parrots jeopardised their external validity. These results provide a promising starting point for validating a set of welfare indicators in parrots.
This chapter is written for conversation analysts and is methodological. It discusses, in a step-by-step fashion, how to code practices of action (e.g., particles, gaze orientation) and/or social actions (e.g., inviting, information seeking) for purposes of their statistical association in ways that respect conversation-analytic (CA) principles (e.g., the prioritization of social action, the importance of sequential position, order at all points, the relevance of codes to participants). As such, this chapter focuses on coding as part of engaging in basic CA and advancing its findings, for example as a tool of both discovery and proof (e.g., regarding action formation and sequential implicature). While not its main focus, this chapter should also be useful to analysts seeking to associate interactional variables with demographic, social-psychological, and/or institutional-outcome variables. The chapter’s advice is grounded in case studies of published CA research utilizing coding and statistics (e.g., those of Gail Jefferson, Charles Goodwin, and the present author). These case studies are elaborated by discussions of cautions when creating code categories, inter-rater reliability, the maintenance of a codebook, and the validity of statistical association itself. Both misperceptions and limitations of coding are addressed.
Demoralization, a prevalent form of psychological distress, significantly impacts patient care, particularly in terminally ill individuals, notably those diagnosed with cancer. This study aimed to assess psychometric properties of Farsi version of Demoralization Scale-II (DS-II) in Iranian cancer patients.
Methods
This study was descriptive-analytical cross-sectional research. The statistical population was cancer patients who sought treatment at Imam Khomeini Hospital in Tehran throughout the 2021–2022. In the initial phase of the study, a preliminary sample comprising 200 patients was carefully selected through convenience sampling. After applying these criteria, 160 patients satisfactorily completed the questionnaires, forming the final study sample. They completed series of questionnaires that included sociodemographic information, DS-II, Scale of Happiness of the Memorial University of Newfoundland, and Beck Depression Inventory (BDI-II). The evaluation included exploratory factor analysis, confirmatory factor analysis (CFA), assessments of convergent validity, and internal consistency reliability.
Results
The CFA revealed a 2-factor model consistent with the original structure. The specific fit indices, including the Comparative Fit Index, Root Mean Square Error of Approximation, and Goodness-of-Fit Index, were 0.99, 0.051, and 0.86, respectively. Significant correlation coefficients (p < 0.05) were found between the DS-II and the Beck Depression and MUNSH Happiness scales. The internal consistency of the DS-II, as measured by Cronbach’s alpha, yielded values of 0.91 for the meaning and purpose factor, 0.89 for the coping ability factor, and 0.92 for the total score.
Significance of results
The Farsi version of DS-II has demonstrated reliability and validity in evaluating demoralization among cancer patients in Iran. This tool can offer valuable insights into the psychological problems of terminally ill patients. Further research opportunities may include conducting longitudinal studies to track demoralization over time and exploring the impact of demoralization on the overall well-being and care of terminally ill patients in Iranian society.
The aim of this study was to develop the Nurse Competency Assessment Scale in Disaster Management (NCASDM) and to conduct psychometric evaluation.
Methods
It is a scale development study. Research data were collected between January and May 2023. In the sample of the study, as stated in the literature, it was aimed to reach at least 10 times the number of draft scale items (n = 600). The psychometric properties of the scale were tested with 697 nurses working in four different hospitals. A three-stage structure was used in the analysis of data: (1) creating the item pool, (2) preliminary evaluation of items, (3) refining of the scale and evaluation of psychometric properties. The content validity, construct validity, internal consistency, and temporal stability of the scale were evaluated according to the scale development guidelines.
Results
The scale items were obtained from online, semi-structured, in-depth individual interviews conducted with nurses who experienced disasters or worked in disasters. The content validity index of the scale was found to be 0.95. According to the exploratory factor analysis, it was found that the scale consisted of 43 items and two subscales, and the subscales explained 79.094% of the total variance. The compliance indices obtained as a result of confirmatory factor analysis were acceptable and at good levels.
Conclusions
The NCASDM was found to be a psychometrically valid and reliable measurement tool. It can be used to evaluate the competency of nurses related to disaster management.
Many books have been written on the topic of second language assessment, but few are easily accessible for both students and practicing language teachers. This textbook provides an up-to-date and engaging introduction to this topic, using anecdotal and real-world examples to illustrate key concepts and principles. It seamlessly connects qualitative and quantitative approaches and the use of technologies, including generative AI, to language assessment development and analysis for students with little background in these areas. Hands-on activities, exercises, and discussion questions provide opportunities for application and reflection, and the inclusion of additional resources and detailed appendices cements understanding. Ancillary resources are available including datasets and videos for students, PowerPoint teaching slides and a teacher's guide for instructors. Packed with pedagogy, this is an invaluable resource for both first and second language speakers of English, students on applied linguistics or teacher education courses, and practicing teachers of any language.
In Chapter 12, the author discusses approaches to judging the effectiveness of both criterion-referenced and norm-reference performance assessments. The chapter includes guidelines for helping create or evaluate performance assessments for particular contexts. It also describes how to use statistical techniques for the same purpose. The chapter presents actual ratings from a classroom-based group oral discussion test and shows how teachers used statistics to determine both score dependability and reliability. The author discusses how to calculate coefficient agreement to help determine the dependability of the assessment and Cronbach’s Alpha to help determine its reliability. A major point of the chapter is that when certain conditions exist, test users can exploit an assessment to determine test takers’ mastery of language criteria (criterion-referenced purpose) and to compare their abilities (norm-referenced purpose). The author provides an appendix that shows readers how to use Excel software to calculate the statistics in the chapter.
In Chapter 4, the author introduces the concept of validity. The chapter begins with an exploration of approaches to defining a construct. These approaches include using language theory, a language needs analysis, corpora, and curriculum objectives to help test developers determine what specific language ability they desire to measure. The chapter emphasizes the importance of alignment, which relates to how well the test content and test taker response processes match the construct’s content and the response processes that the test aims to measure. The author uses a detailed example of assessing children’s ability to communicate on a playground in a second language. The major point of the example is that the assessment should require children to use the same kinds of language they use when they communicate on the playground. This alignment helps ensure that the assessment measures the targeted language ability and will lead to positive washback on teaching and learning.
This methodological study aimed to establish the validity and reliability of the Turkish version of the Information Concealment Scale for Caregivers of palliative care patients.
Methods
The study was conducted between January and June 2023 with 155 caregivers who cared for patients hospitalized in the palliative care units of 2 hospitals in Istanbul, Turkey. Exploratory factor analysis and confirmatory factor analysis were performed for validity analysis. Cronbach’s α, item-total correlation, intraclass correlation coefficient (ICC), and Pearson correlation analysis were used for reliability analysis.
Results
Of the participants, 54.2% were female and 69% were married. The mean age was 37.96 ± 12.25 years. According to the exploratory factor analysis, the scale consisted of 3 subscales and 15 items. The first subscale of the scale was expressed as “misrepresentation of the disease’; the second subscale was defined as “concealment of information”; the third subscale was defined as “misrepresentation of the real situation.” As a result of the modifications made in confirmatory factor analysis, the goodness-of-fit values were as follows: CMIN/DF(X2/Sd) = 175.16/815 = 2.16; GFI = 0.88; CFI = 0.91; RMSEA = 0.079; RMR = .070; NFI = 0.90. The Cronbach’s α values of the subscale were between 0.79 and 0.87. ICC values were between 0.90 and 0.95 at a confidence interval of 95%. A positive correlation was determined between the subscales.
Significance of results
It was determined that the Turkish version of the Information Concealment Scale was a valid and reliable tool for caregivers.
Existing self-rated depression measurement tools possess a range of psychometric drawbacks, spanning a range of validity and reliability constructs. The gold standard self-rated depression scales contain several variable items that are often non-specific, require respondents to have a certain level of language understanding and limited scoring options resulting in low sensitivity. The Maudsley three-item visual analogue scale (M3VAS) was developed to address these challenges.
Aims
This study aimed to translate the M3VAS into Chinese and test its reliability and validity.
Method
First, both M3VAS scales (assessing current severity and change in severity) were translated according to a standardised protocol to finalise the Chinese version. Reliability and validity were then examined among 550 young people with moderate to severe depression (patient health questionnaire-9 (PHQ-9) score ≥15) in a cross-sectional opportunistic questionnaire survey.
Results
The content validity of each item (six items, across both scales) ranged from 0.83 to 1.00. Exploratory factor analysis denoted a total of two common factors, with a variance contribution rate of 64.34%. The total score correlated positively with the PHQ-9 total score (r = 0.241, P < 0.01). The Chinese version of the M3VAS had good reliability and validity values, and the confirmatory factor model fit well.
Conclusions
The psychometric properties of the Chinese version of the M3VAS suggest that this scale can feasibly evaluate depression among young people in China.
Despite the growing interest in the prevalence and consequences of loneliness, the way it is measured still raises a number of questions. In particular, few studies have directly compared the psychometric properties of very short measures of loneliness to standard measures.
Methods
We conducted a large epidemiological study of midwife students (n = 1742) and performed a head-to-head comparison of the psychometric properties of the standard (20 items) and short version (3 items) of the UCLA Loneliness Scales (UCLA-LS). All participants completed the UCLA-LS-20, UCLA-LS-3, as well as other measures of mental health, including anxiety and depression.
Results
First, as predicted, we found that the two loneliness scales were strongly associated with each other. Second, when using the dimensional scores of the scales, we showed that the internal reliability, convergent-, discriminant-, and known-groups validities were high and of similar magnitude between the UCLA-LS-20 and the UCLA-LS-3. Third, when the scales were dichotomized, the results were more mixed. The sensitivity and/or specificity of the UCLA-LS-3 against the UCLA-LS-20 were systematically below acceptable thresholds, regardless of the dichotomizing process used. In addition, the prevalence of loneliness was strikingly variable as a function of the cut-offs used.
Conclusions
Overall, we showed that the UCLA-LS-3 provided an adequate dimensional measure of loneliness that is very similar to the UCLA-LS-20. On the other hand, we were able to highlight more marked differences between the scales when their scores were dichotomized, which has important consequences for studies estimating, for example, the prevalence of loneliness.
The Personal Need for Structure (PNS) scale assesses individuals’ tendency to seek out clarity and structured ways of understanding and interacting with their environment. The main aim of this study was to adapt the PNS scale to Spanish and assess its psychometric properties. There are two versions of the PNS scale being used, which vary in the number of dimensions (1 vs. 2), and in the number of items (12 vs. 11; because one version excludes Item 5). Therefore, an additional aim of this study was to compare the two existing versions of the PNS scale. This comparison aimed to address the debate regarding the inclusion of Item 5, and the number of dimensions that comprise the PNS scale. A sample of 735 individuals was collected. First, through an approach combining exploratory and confirmatory analyses, evidence was found in favor of the scale being composed of two related but distinguishable factors: Desire for Structure and Response to the Lack of Structure. Scores on these subscales showed acceptable internal consistency and test-retest reliability. Evidence supporting the invariance of the internal structure across sociodemographic variables such as gender and age was found. Validity evidence was also analyzed by examining the relationships with other relevant measures. The results indicated that Item 5 can be excluded without reducing scores validity or reliability, which supports preceding research in the literature. In conclusion, the PNS scale was satisfactorily adapted to and validated in Spanish and its use in this context is recommended.
The focus of the chapter is on turning concepts into measurable variables, also known as operationalization.Best practices in created variable based on the concept are covered.The differences between nominal, ordinal, and interval level variables are discussed along with their relevance for statistical tests later covered in the book.The importance of measurement validity and reliability and their implications for research provide another focus of the chapter.
