Validity and reliability of the Arabic version of the "Personal Wellbeing Index-Adults" on adults with hearing impairment

Background: The Personal Wellbeing Index-Adults (PWI-A) is the most widely used instrument for measuring subjective-quality of life (QoL). The current study seeks to investigate the construct validity and reliability of the Arabic version of the PWI-A on adults with bilateral hearing impairment by comparing the single-factor solution with the two-factor solution. Methods: A cross-sectional study was conducted at the Audio-Vestibular Medicine Unit of Alexandria University from July-2017 to January-2018. A total of 205 adults were interviewed to measure the subjective-QoL using the PWI-A instrument. Internal consistency was determined using both Cronbach’s alpha and composite reliability (CR). Validity was assessed by construct validity, including ordinal regression, ordinal exploratory factor analysis (OEFA), and ordinal confirmatory factor analysis (OCFA). Results: The first four items of the PWI-A which are: satisfaction with living standard, health, achievements, and relationships were the most important indicators of subjective-wellbeing (Part r2 0.0547, 0.0324, 0.0361, and 0.0225, respectively). OEFA suggested that the two-factor model contributes better than the single-factor model. OCFA validated this suggested solution; (two-factor: RMSEA=0.084 (90% CI=0.01-0.14); CFI=0.964; AIC=52.64; single-factor: RMSEA=0.119 (90% CI=0.07-0.17); CFI=0.922; AIC=62.77). Good internal consistency was also presented (two-factor: Cronbach’s alpha=0.719, 0.693; single-factor: Cronbach’s alpha = 0.750). Conclusion: The Arabic version of the PWI-A is a multidimensional scale that consists of two dimensions: the first is related to subjective-QoL, and the second is related to satisfaction with the community. Thus, it is recommended to use the short version of the PWI-A with only four items to measure subjective-QoL, as it achieved sufficient reliability and construct validity.

Ethical Climate Questionnaire

Background: An ethical climate has been described as a working climate embracing shared perceptions about morally correct behaviour concerning ethical issues. Various ethical climate questionnaires have been developed and validated for different contexts, but no questionnaire has been found concerning the ethical climate from an inter-professional perspective in a healthcare context. The Swedish Ethical Climate Questionnaire, based on Habermas’ four requirements for a democratic dialogue, attempts to assess and measure the ethical climate at various inter-professional workplaces. This study aimed to present the construction of and to test the psychometric properties of the Swedish Ethical Climate Questionnaire. Method: An expert group of six researchers, skilled in ethics, evaluated the content validity. The questionnaire was tested among 355 healthcare workers at three hospitals in Sweden. A parallel analysis (PA), an exploratory factor analysis and confirmatory factor analysis were performed. Ethical considerations: The participants included in the psychometric analysis were informed about the study, asked to participate in person and informed that they could withdraw at any time without giving any reason. They were also assured of confidentiality in the reporting of the results. Findings: The parallel analysis (PA) recommended one factor as a solution. The initial exploratory factor analysis with a four-factor solution showed low concordance with a four-factor model. Cronbach’s alpha varied from 0.75 to 0.82; however, since two factors only consisted of one item, alpha could not be reported. Cronbach’s alpha for the entire scale showed good homogeneity (α = 0.86). A confirmatory factory analysis was carried out based on the four requirements and showed a goodness-of-fit after deleting two items. After deletion of these items, Cronbach’s alpha was 0.82. Discussion: Based on the exploratory factor analysis, we suggest that the scale should be treated as a one-factor model. The result indicates that the instrument is unidimensional and assesses ethical climate as a whole. Conclusion: After testing the Swedish Ethical Climate Questionnaire, we found support for the validity and reliability of the instrument. We found the 10-item version of Swedish Ethical Climate Questionnaire satisfactory. However, we found no support for measuring different dimensions and, therefore, this instrument should be seen as assessing ethical climate as of whole.

Today, many organizations have realized an important of pre-development process in order to compete with competitor through drastically introduce new product in the market. In view of that, understanding critical factors that contribute to successful pre-development process implementation is becoming the more important. However, most of past studies were conducted in large organization, very little has been done in small and medium enterprise (SMEs). SMEs have certain limitation in terms of their financial, human, technical, and resources that could hinder their progress towards implementing pre-development process. This paper reviews and analyses CSFs developed by previous authors in order to propose a set of CSFs which were thought to be critical for SMEs. After that the questionnaire developed in this study will be analysis using factors analysis and reliability test in order to examine construct validity and reliability. An initial draft of the questionnaire was developed based on the literature. The questionnaire was pre-tested by academicians and industry practitioners. After that the questionnaire was piloted at 55 food and beverage manufacturing SMEs to check its reliability by using Cronbach’s alpha value. In addition, principle component analysis was carried out to test the construct validity. All the factors in the survey instrument had a Cronbach’s alpha coefficient of more than 0.7 which may be considered satisfactory. Through factor analysis, all KMO values were found above acceptable value of 0.50. All Bartlett’s Test in this analysis was found to be significant. Therefore the instrument is valid and reliable and considered as satisfactory. Nine CSFs, which are believed suitable for SMEs have been proposed in this paper. Through systematic identification and validation, it is hope that the set of CSFs could be used as guides for SMEs to implement pre-development process successfully.

The Impact

Introduction It is required to have validated instruments in health science students that identify unhealthy habits and assess the impact of educational interventions and programs aimed at promoting a healthy lifestyle. Objective To evaluate the validity and reliability of an instrument to measure medical students' lifestyles. Methods A lifestyle questionnaire was developed using the Delphi technique by a group of experts. The final questionnaire was applied to 332 students of the School of Medicine of the Ricardo Palma University in 2017. A preliminary examination was carried out to assess preconditions for construct validity—including the correlation matrix, the Kaiser Meyer Olkin statistic, and the Bartlett sphericity test. Factor analysis was used for construct validity, and the possible resulting factors were extracted through the principal component analysis. Cronbach's alpha coefficient was calculated to assess the instrument reliability. Results In this study, 41.6% of participants were men with a mean age of 20 years (standard deviation = 3). The preconditions for the factor analysis were a Kaiser Meyer Olkin coefficient = 0.773 and a significant Bartlett sphericity test. For the 47 items of the final questionnaire, the factor analysis showed an explained variance of 56.7% with eigenvalues greater than one. Cronbach's alpha was 0.78. The final questionnaire could assume values between -23 to 151 points. Based on a cut point of 71 points, the prevalence of students with an unhealthy lifestyle was 73.6%. Conclusion The developed instrument has acceptable validity and reliability to measure lifestyle in medical students. For external validation, studies in other university populations are suggested.

This study aims to investigate the construct validity and reliability of the checklist for qualitative analysis of the overhand serve in Volleyball. Fifty-five male subjects aged 13-17 years participated in the study. The overhand serve was analyzed using the checklist proposed by Meira Junior (2003), which analyzes the pattern of serve movement in four phases: (I) initial position, (II) ball lifting, (III) ball attacking, and (IV) finalization. Construct validity was analyzed using confirmatory factorial analysis and reliability through the Cronbach’s alpha coefficient. The construct validity was supported by confirmatory factor analysis with the RMSEA results (0.037 [confidence interval 90% = 0.020-0.040]), CFI (0.970) and TLI (0.950) indicating good fit of the model. In relation to reliability, Cronbach’s alpha coefficient was 0.661, being this value considered acceptable. Among the items on the checklist, ball lifting and attacking showed higher factor loadings, 0.69 and 0.99, respectively. In summary, the checklist for the qualitative analysis of the overhand serve of Meira Junior (2003) can be considered a valid and reliable instrument for use in research in the field of Sports Sciences.

Abstract Background Dealing with the spiritual needs of patients has been recognized as one of the principles of holistic care in nursing. Therefore, it is necessary for nurses to deal with the spiritual issues of patients. Also, a valid and reliable scale is needed to measure nurse-provided spiritual care. So the purpose of this study was to determine the validity and reliability of the Persian version of the “Nurse Spiritual Care Therapeutics Scale” in Iranian nurses. Method In a methodological study, English version of the Nurse Spiritual Care Therapeutics Scale was translated into Persian by forward–backward translation procedure. Face validity was assessed by cognitive interview, and content validity was assessed by a panel of experts. In addition, construct validity was assessed by exploratory factor analysis. The participants were 188 nurses working in different adult wards. Reliability was measured using the Cronbach’s alpha and stability reliability was assessed using the internal correlation coefficient (ICC). Results In assessing the construct validity, two factors with eigenvalues greater than 1 were identified, which explained 58.47% of the total variance. Cronbach’s alpha value was 0.932, and ICC was 0.892. Conclusion As a result, the Persian version of the Nurse Spiritual Care Therapeutics Scale shows a good validity and reliability. Therefore, this scale can be used to evaluate spiritual care at the bedside in Iran.

Background and objectives Nurses’ caring behaviors, professional activities, and behaviors for the benefit of patients, influence patients’ perception of care and satisfaction with the quality of care provided. Caring behaviors of nurses are contextual and various factors such as patients’ social structure, lifestyle, culture, and interests, as well as their biographical, social, and physiological characteristics, can influence perceptions of caring behaviors of nurses, as caring behaviors are an interactive and mental process between patients and nurses. This study was conducted to provide a transcultural translation and psychometric analysis of Caring Behaviors Inventory (CBI) among nurses in Iran. Methodology Transcultural translation of the 16-item CBI was performed. Then, face validity (qualitative), content validity (quantitative and qualitative), and construct validity were examined in a cross-sectional study of 509 patients. A demographic questionnaire and the 16-item CBI were sent to enrolled patients via online questionnaires. The reliability of the instrument was assessed by internal consistency using Cronbach’s alpha. Then, construct validity of the single factor CBI was assessed using Confirmatory Factor Analysis (CFA). Since one factor CBI was not confirmed, construct validity was examined using Exploratory Factor Analysis (EFA). The final number of factors was confirmed using CFA. Results The internal consistency of the instrument was good with Cronbach’s alpha 0.89. Based on EFA, the CBI were loaded on two factors, eigenvalues >1, no item was removed. The emergent factors were named "Communicating respectfully" and "Professional knowledge and skill". These two factors explained 50.197% of the total variance. Then, CFA showed an acceptable fit for the two factors CBI. Conclusion The results showed that the Persian version of the 16-item CBI had adequate validity and reliability. Accordingly, this instrument can be used to study nurses’ caring behaviors.

IntroductionPerson-centred maternity care (PCMC), which refers to care that is respectful and responsive to women’s preferences needs, and values, is core to high-quality maternal and child health. Provider-reported PCMC provision is a potentially valid means of assessing the extent of PCMC and contributing factors. Our objectives are to assess the psychometric properties of a provider-reported PCMC scale, and to examine levels and factors associated with PCMC provision.MethodsWe used data from two cross-sectional surveys with 236 maternity care providers from Ghana (n=150) and Kenya (n=86). Analysis included factor analysis to assess construct validity and Cronbach’s alpha to assess internal consistency of the scale; descriptive analysis to assess extent of PCMC and bivariate and multivariable linear regression to examine factors associated with PCMC.FindingsThe 9-item provider-reported PCMC scale has high construct validity and reliability representing a unidimensional scale with a Cronbach’s alpha of 0.72. The average standardised PCMC score for the combined sample was 66.8 (SD: 14.7). PCMC decreased with increasing report of stress and burnout. Compared with providers with no burnout, providers with burnout had lower average PCMC scores (β: −7.30, 95% CI:−11.19 to –3.40 for low burnout and β: −10.86, 95% CI: −17.21 to –4.51 for high burnout). Burnout accounted for over half of the effect of perceived stress on PCMC.ConclusionThe provider PCMC scale is a valid and reliable measure of provider self-reported PCMC and highlights inadequate provision of PCMC in Kenya and Ghana. Provider burnout is a key driver of poor PCMC that needs to be addressed to improve PCMC.
