Orem's Theory

The purposes of this study were to evaluate the psychometric properties of English and Spanish instruments that measure the nutrition behavior and practices of children and their parents. Orem’s self-care deficit nursing theory was used in this methodological study. A convenience sample of 333 children and 262 mothers participated from two schools in Washington, D.C. and two schools in Santiago, Chile. Principal component analysis indicated three component per instrument corresponding to Orem’s Theory of operations demonstrating construct validity of the instrument. The study findings showed evidence for validity and reliability of the English and Spanish versions and indicated that the instruments appropriately represented Orem’s operations. The results have implications for the development of health behavior measurement instruments that are valid, reliable, designed for children, culturally appropriate, and efficient. Measuring the nutrition behavior of children and parents is critical for determining the effectiveness of nutrition intervention programs. Furthermore, instruments are needed so that researchers can compare corresponding child and parent behaviors or compare behaviors across cultures.

Background and Objective. The Moore Index of Nutrition Self-Care (MIN-SC) questionnaire has been used widely in both English and Spanish languages. The purpose of this study is to convert MIN-SC into the Arabic language and to test the translated tool for validity and reliability among adolescents in Saudi Arabia. Method. The psychometric characteristics of MIN-SC were assessed using college freshman students at King Saud University in Riyadh, Saudi Arabia. The validity and reliability were examined using Cronbach’s alpha coefficient. The construct validity was examined through principal component analysis. Results. The MIN-SC instrument was shown to be internally consistent with reliable scoring (Cronbach’s alpha = 0.910). Exploratory factor analysis resulted in 42 items loading on three main components: estimative, production, and transitional, with a factor loading of eigenvalues >2. The final model explained 38% of the variance. Conclusion. The Arabic version of MIN-SC was shown to be a valid and reliable tool for assessing attitude toward nutrition among adolescent students.

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.

Effective Assessment

Performance Assessment of Self-Care Skills (PASS) is a performance-based scale developed in the United States. Because of cultural differences, a Portuguese version was developed, then validated in the Portuguese population and tested ensuring reliability. The objective of this study was to create and test psychometric properties of a Portuguese version of PASS. A linguistic validation on older adults with physical/cognitive disabilities enabled us to validate P-PASS. Some original tasks were changed. Data were analyzed by PASS constructs (independence-safety adequacy), age, and gender. Construct validity (known-group analyses, factor analyses), with 98 individuals yielded excellent results. Reliability between two observers for 30 participants yielded almost perfect agreement for all three constructs. Independence scores were highest, followed by safety and adequacy. Men presented greater independence, as well as participants <60 years. We obtained results comparable with the original version. Conclusion. P-PASS is valid and reliable for the Portuguese population, enabling effective assessment of function and measurement of health outcomes.

IntroductionSymptom perception in heart failure (HF) has been identified as crucial for effective self-care, and is related to patient and health system outcomes. There is uncertainty regarding the feasibility and acceptability of symptom perception support and doubts regarding how to include informal caregivers. This study aims to test the feasibility, acceptability and outcome responsiveness of an intervention supporting symptom perception in persons with HF and their informal caregiver.Methods and analysisA feasibility study with a quasi-experimental pretest and post-test single group design is conducted. The convenience sample consists of 30 persons with HF, their informal caregivers and six nurses. SYMPERHEART is an evidence-informed intervention that targets symptom perception by educational and support components. Feasibility is measured by time-to-recruit; time-to-deliver; eligibility rate; intervention delivery fidelity rate. Acceptability is measured by rate of consent, retention rate, treatment acceptability and the engagement in the intervention components. Outcome responsiveness includes: HF self-care (via the Self-care of Heart Failure Index V.7.2); perception of HF symptom burden (via the Heart Failure Somatic Perception Scale V.3); health status (via the Kansas City Cardiomyopathy Questionnaire-12); caregivers’ contribution to HF self-care (via the Caregiver Contribution to Self-Care of Heart Failure Index 2); caregivers’ burden (via the Zarit Burden Interview). Clinical outcomes include HF events, hospitalisation reason and length of hospital stay. Descriptive statistics will be used to report feasibility, acceptability, patient-reported outcomes (PRO) and clinical outcomes. PRO and caregiver-reported outcome responsiveness will be reported with mean absolute change and effect sizes.Ethics and disseminationThe study is conducted according to the Declaration of Helsinki. The Human Research Ethics Committee of the Canton of Vaud, Switzerland, has approved the study. Written informed consent from persons with HF and informal caregivers are obtained. Results will be published via peer reviewed and professional journals, and further disseminated via congresses.Trial registration numberISRCTN18151041.

Abstract Background The Client Satisfaction with Devices (CSD) module of the Orthotics and Prosthetics Users’ Survey is an extensively used questionnaire that measures patients’ satisfaction with orthosis and prosthesis. However, the validated version for Arabic speakers (CSD-Ar) is only applicable for orthosis users. Objectives The aim of this study was to evaluate the psychometric proprieties of the CSD-Ar for prosthetics users. Methods The study used a convenience sample of prosthesis users from Saudi Arabia and Turkey (N = 183), who completed the CSD-Ar. The collected data were analysed using Rasch analysis to evaluate item fit, reliability indices, item difficulty, local item dependency, and differential item functioning (DIF) using WINSTEPS version 4.6.1. Results Based on the analysis, the four-response Likert-scale was acceptable, as shown by the category functioning test, All eight items did achieve a fit to the Rasch Model [(infit) and (outfit) mean-square 0.75 to 1.3]. Person separation reliability was 0.76, and item separation reliability was 0.94. A principal component analysis (PCA) showed satisfactory unidimensionality and no local item dependency. The DIF analysis showed no notable dependency among items on participant characteristics in terms of age, gender, duration of use, country, and level of amputation. Conclusion This study contributes to the confidence of using CSD-Ar to evaluate users’ satisfaction with different prostheses, affirming the need for further refinement of the quality of the outcome measure.

Abstract Background In a context where there is no treatment for the current COVID-19 virus, the combination of self-care behaviours together with confinement, are strategies to decrease the risk of contagion and remain healthy. However, there are no self-care measures to screen self-care activities in general population and which, could be briefly in a lockdown situation. This research aims to build and validate a psychometric tool to screen self-care activities in general population. Methods Firstly, an exploratory factor analysis was performed in a sample of 226 participants to discover the underlying factorial structure and to reduce the number of items in the original tool into a significant pool of items related to self-care. Later a confirmatory factor analyses were performed in a new sample of 261 participants to test for the fit and goodness of factor solutions. Internal validity, reliability, and convergent validity between its score with perceived stress and psychological well-being measures were examined on this sample. Results The exploratory analyses suggested a four-factor solution, corresponding to health consciousness, nutrition and physical activity, sleep, and intra-personal and inter-personal coping skills (14 items). Then, the four-factor structure was confirmed as the best model fit for self-care activities. The tool demonstrated good reliability, predictive validity of individuals’ perception of coping with COVID-19 lockdown, and convergent validity with well-being and perceived stress. Conclusions This screening tool could be helpful to address future evaluations and interventions to promote healthy behaviours. Likewise, this tool can be targeted to specific population self-care’s needs during a scalable situation.

The construct validity and reliability of the 1987 Perceived Physical Competence Scale of Lintunen were examined to assess the applicability of the instrument for use with adolescents with disabilities. Subjects were 51 girls and 34 boys ( M age = 15.1 yr.) from several schools in central Finland. Principal component factor analysis with varimax rotation yielded the same two factors for adolescents with disabilities as reported for nondisabled adolescents in the related literature. Cronbach alphas for the two factors were .89 and .56. It was concluded that the scale is an appropriate measure for adolescents with disabilities. Statistical analysis indicated no gender differences for adolescents with disabilities. When compared with nondisabled groups in the related literature, these adolescents had perceived fitness similar to nondisabled peers but significantly lower than that of athletes without disabilities.

Background and Purpose: Some women avoid routine Pap testing because of negative attitudes and beliefs. The ability to measure these factors is limited by lack of valid and reliable tools. Therefore, this article describes steps taken to test a measure. Methods: Validity and reliability testing of psychometric scales was conducted. Results: Sample consisted of 344 women. Using principal component analysis resulted in 4 components: Exam-Related Factors, Benefits, Vulnerability, and Risks and Barriers. Revised scale included 28 items explaining 46% variance, with good internal consistency (α = .84). Women who did not routinely screen exhibited significantly more negativity. Conclusions: The measure demonstrates validity and reliability across different groups of women and can be used to inform the design of individualized interventions to promote repeat screening.

Background: Generalised anxiety disorder (GAD) frequently occurs amongst patients with tuberculosis (TB) and contributes to poor quality of life and treatment outcomes. This study evaluated the construct validity and reliability of the GAD-7 scale in a sample of patients with TB in the Free State Province.Methods: A pilot study was conducted amongst a convenience sample of 208 adult patients newly diagnosed with drug-susceptible TB attending primary healthcare (PHC) facilities in the Lejweleputswa District in the Free State. A structured interviewer-administered questionnaire comprising social demographic questions and the GAD-7 scale was used. Confirmatory factor analysis was used to investigate the construct validity of the GAD-7 scale. The reliability of the scale was assessed by calculating Cronbach’s alpha.Results: The analysis showed that a modified two-factor (somatic symptoms and cognitive -emotional symptoms) model, in which the items ‘Not being able to stop or control worrying’ and ‘Worrying too much about different things’ were allowed to covary (Comparative Fit Index: 0.996, Tucker–Lewis Index: 0.993, Root Mean Square Error of Approximation: 0.070, 90% confidence interval: 0.032–0.089), fitted the data better than a unidimensional (generalised anxiety) or an unmodified two-factor model. The indicators all showed significant positive factor loadings, with standardised coefficients ranging from 0.719 to 0.873. The Cronbach’s alpha of the scale was 0.86.Conclusion: The modified two-factor structure and high internal consistency respectively provide evidence for construct validity and reliability of the GAD-7 scale for assessing GAD amongst patients with TB. Studies are necessary to assess the performance of this brief scale under routine TB programme conditions in the Free State.
