DEVELOPMENT OF PELVIC FLOOR HEALTH KNOWLEDGE QUIZ IN TURKISH PEOPLE: VALIDITY AND RELIABILITY

Purpose: Although pelvic floor problems are a wide and important issue, the tools that question individuals’ knowledge level related to these problems are not comprehensive and sufficient. This study aimed to develop a Pelvic Floor Health Knowledge Quiz (PFHKQ) and to determine its validity and reliability. Methods: A 37-item quiz was prepared to comprehensively measure the participants' knowledge of pelvic floor health and administered in 370 participants. Face validity, content validity, construct validity and known-group validity were analyzed. The Person Separation Index (PSI) and the Kuder-Richardson-20 (KR-20) coefficient values were calculated for reliability. Results: The face validity analysis showed that all items of the test were quite understandable (range 83.02%-98.11%). According to the Rasch model, a knowledge quiz with three subscales (function/dysfunction; risk/etiology; diagnosis and treatment) and 29 items were defined. Individuals who were health professionals or students in the health field had more knowledge based on the scores they received from the PFHKQ compared to the other participants (p < 0.05). There were differences between the participants' knowledge scores in terms of previously having heard of any pelvic floor problems and pelvic floor exercises (PFE) (p < 0.05). It was found that the PSI and the KR-20 values were 0.892 and 0.890 for the function/dysfunction subscale, 0.938 and 0.920 for the risk/etiology subscale, 0.912 and 0.924 for the diagnosis and treatment subscale, and 0.952 and 0.926 for the PFHKQ total score, respectively. Conclusion: The PFHKQ was found to be a valid and reliable tool in the Turkish people.

Antibiotic stewardship knowledge and belief differences among healthcare professionals in hospitals: A survey study

BackgroundCollaborative practice in healthcare has been recommended to improve the quality of antimicrobial stewardship interventions, a behavioral change in antimicrobial use. Insufficient knowledge regarding antibiotic resistance, the fear of complications from infections, and how providers perceive antibiotic use and resistance are likely to influence prescribing behavior. This study's objective was to identify the knowledge and belief healthcare professionals' differences about antibiotic stewardship. MethodsThis cross-sectional survey study of three hospitals in the East Java province, Indonesia utilized a 43-item questionnaire to assess antimicrobial stewardship knowledge and belief. There were 12 knowledge questions (total possible score: 12) and 31 belief questions (total possible score: 155). The Kuder Richardson 20 (KR-20) and Cronbach alpha values of the questionnaire were 0.54 and 0.92, respectively. ResultsOut of the 257 respondents, 19% (48/257) had a low scores of knowledge, and 39% (101/257) had low scores on belief about antibiotic stewardship (101/257). Most midwives had a low scores on knowledge (25/61) and low scores on belief (46/61). Respondents with high scores on belief were 17% (10/59) physicians, 15% (4/27) pharmacists, 8% (5/65) nurses, and 3% (2/61) midwives. ConclusionAmong healthcare professionals, knowledge and belief differences concerning antibiotic stewardship vary widely. These differences will affect their capability, behavior, and contribution to the healthcare team collaboration and performance. Further studies are needed to evaluate the correlation between the level of inter-professional collaboration and the quality of the antibiotic stewardship implementation.

Importance of establishing validity and reliability of reading test

This study presents the processes of developing and establishing reliability and validity of a reading test. In this respect, the study was conducted among 43 undergaduate students at Mongolian University of Science and Technology. Such detailed assessment is highly recommended for researchers who are in need of preparing pre and post tests which are different from each other. The results of students’ achievement in this test were utilized to determine the quality of each particular item in terms of item difficulty and item discrimination analysis. Item difficulty, commonly known as p-value refers to the proportion of examinees that responded to the item correctly. To test the reliability of the reading test, item analysis was employed in terms of item difficulty, discrimination, average and variance of the test scores. The quality of the item as a whole indicates a reliable value Kuder-Richardson 20 (KR20) value of 0.71.

Development and psychometric evaluation of the Social Connectedness Index in nursing home residents with Alzheimer's disease and dementia using the Minimum Data Set 3.0.

To develop a reliable and valid measure of social connectedness among nursing home residents with Alzheimer's disease and related dementias (ADRD) using items available in the Minimum Dataset 3.0 (MDS). We conducted a retrospective scale development study using the 2016 MDS with two populations of nursing home residents with ADRD: (1) new admissions (not post-acute care) (n=146,694); (2) residents with comprehensive annual assessments (n=294,704). Twenty-nine items were included for consideration. Psychometric evaluation included content validity, item analysis, internal consistency reliability, criterion-related validity, and exploratory factor analysis. Analyses were stratified by self- or staff-assessed pain. The resulting five item Social Connectedness Index (SCI) has good content (Fleiss Kappa=0.67), criterion-related and construct validity and adequate internal consistency reliability (Kuder Richardson-20: 0.63-0.74) in persons with ADRD. As anticipated, younger residents, men, and those with severe cognitive impairment, anxiety, and depression were more likely to be categorized in the low social connectedness group. The SCI is a promising measure for estimating the amount of social connectedness present for nursing home residents with ADRD. Further work needs to be done to evaluate the usefulness of the SCI for evaluating health and well-being among this population over time.

Validation of the Chinese Version of the Coronary Artery Disease Education Questionnaire - Short Version: A Tool to Evaluate Knowledge of Cardiac Rehabilitation Components.

Background:Patient education is the first step in implementing a cardiac rehabilitation (CR) program and a powerful tool for promoting behavioral changes in cardiac patients. In China, the clinical workload is so heavy that a short and reliable tool for assessing disease-related knowledge is needed for targeted patient education.Objective:The aim of this study was to translate, adapt and validate the Chinese version of the Coronary Artery Disease Education Questionnaire – Short Version (CADE-Q SV).Methods:The CADE-Q SV was translated to simplified Chinese and culturally adapted to the Chinese context. The translated version was reviewed by a committee of seven experts in cardiovascular disease, and the content validity of the questionnaire was established. The psychometric properties of the questionnaire were analyzed considering the responses of 240 CR patients. The Kuder-Richardson-20 (KR-20) coefficient and Cronbach’s alpha were used to assess internal consistency. The intraclass correlation coefficient (ICC) was used to assess test-retest reliability. The criterion-related validity was evaluated by determining whether there were differences in the total scores of patients with different educational levels. Confirmatory factor analysis (CFA) was used to assess the factor structure.Results:Three items from the original version were adapted to reflect Chinese culture. The content validity index was 0.94. The KR-20 score was 0.856. All ICC values were > 0.70. The knowledge scores of patients with different educational levels were significantly different, indicating that the criterion-related validity of the Chinese CADE-Q-SV was acceptable. CFA validated the five-factor structure of the Chinese CADE-Q-SV.Conclusion:The Chinese CADE-Q SV questionnaire has good reliability and validity. This short, efficient tool can be completed quickly, assess disease-related knowledge in cardiovascular patients and serve as a reference for individualized patient education in China.

Validation of the French-Canadian Version of a Short Questionnaire to Assess Knowledge in Cardiac Patients (CADE-Q SV).

The long-term success of cardiac rehabilitation programs rests in part on the patient's ability to maintain health behaviors, which is influence by the patient education received. Therefore, a short and reliable tool to assess patients' knowledge is warranted. The aim of this study was to translate, culturally-adapt and psychometrically validate the French-Canadian version of the Coronary Artery Disease Education Questionnaire Short Version (CADE-Q SV). The French CADE-Q SV - translated and culturally-adapted - was reviewed by 3 bilingual experts in cardiovascular disease. This version was then psychometrically tested in 115 CR patients in two Canadian provinces (Québec and New Brunswick). The questionnaire was completed at patients' first CR session and in the end of their 6-month program to assess interpretability. The internal consistency was assessed using Kuder-Richardson-20 (KR-20) and Cronbach's alpha, factor structure using confirmatory factor analysis, and criterion validity regarding level of education and family income. KR-20 was 0.72. Factor analysis revealed 5 factors, all internally consistent. Criterion validity was supported by significant differences in total scores by educational level and family income (p < 0.05). Results showed that increases in knowledge can moderately increase mean steps per day and peakVO2, with an MCID of 3.00. The overall mean was 15.7 ± 2.0. The area with the highest knowledge was risk factors and the lowest was psychosocial risk. The French-Canadian CADE-SV was demonstrated to have good validity and reliability.

Development of a high-risk neonatal infection control competency scale.

The purpose of this study was to develop a scale to measure high-risk neonatal infection control competency among nurses in neonatal intensive care units (NICUs). The study participants included 251 nurses working in NICUs at seven hospitals in South Korea. The scale was designed to measure high-risk neonatal infection control competency in terms of performance (HirNICCS_P) and knowledge (HirNICCS_K), which were addressed by 42 and 54 items, respectively, and was initially subjected to content validity testing by a panel of experts in neonatal nursing. The items were divided into five factors: (1) basic care, (2) skin care, (3) feeding management, (4) medication and invasive procedures, and (5) environment management. After participant completion of the scale, construct validity was examined using exploratory and confirmatory factor analyses, and internal reliability tests were also performed. The total variance of validity was 53.7% for HirNICCS_P, and the Cronbach's alpha values for reliability were .95 for HirNICCS_P and .67 for HirNICCS_K based on a Kuder-Richardson-20 test. We concluded that this scale can be used to assess the performance and knowledge with regard to infection control competency among neonatal nurses and that its application can support strengthening of infection control education for nurses who score low on performance and knowledge competency.

Scientific Explanation of Phenomenon, Imagination and Concept Formation as Correlates of Students’ Understanding of Physics Concepts

Knowledge of physics to many students is described in quantitative terms such as how much scientific vocabulary and how many formulae have been memorized. However, only few students can successfully make connections to apply the scientific knowledge in answering questions in physics. That is, physics students answer questions in relation to their emergent views mainly based on their prior knowledge about everyday experience which is at variance with scientific knowledge in a typical physics classroom. It is evident that teaching and learning of physics concepts introduced in verbal and mathematical definitions may not promote conceptual understanding of physics even after instruction. Therefore, no relationship exists between students, prior knowledge in physics and scientific understanding of physics concepts as they attempt to answer physics questions that probe their scientific understanding. Hence, the main purpose of this study was to ascertain if relationship exist among scientific explanation of phenomenon, imagination and concept formation (predictor variables) and students’ understanding of physics concepts (criterion) and amount of variation in the criterion variable that can be attributed to the predictor variables. The study adopted a correlation research design. The sample of the study was 385 respondents drawn from the population of Senior Secondary III Physics Students of 2016/2017 academic session in the government owned secondary schools in Akure Education Zone of Ondo State. The instruments for data collection were four namely: Students’ Scientific Explanation of Phenomenon Test (SSEPT), Students’ Scientific Imagination Scale (SSIS), Students’ Scientific Concept Formation Test (SSCFT), and Students’ Understanding of Physics Concept Test (SUPCT). SSEPT and SUPCT were ten (10) structured essay questions each. The internal consistency indices obtained were 0.81 and 0.86 respectively. An internal consistency of twenty (20) item structured questionnaire of (SSIS), modeled on a four (4) point rating was determined using Cronbach Alpha formula and was found to be scale 0.85.Also, the internal consistence index of SSCFT with twenty multiple choice items was determined using Kuder-Richardson 20 (K-R20) Formula and was found to be 0.82. The research questions were answered using Pearson-Product Moment Correlation and coefficient of determination The Null hypotheses were tested using Multiple-Regression analysis at.05 level of significance. Results showed that there was a statistically significant relationship among students’ scientific explanation of phenomenon, students’ scientific imagination, students’ scientific concept formation and students’ understanding of physics concepts. It was recommended among other things that Physics teachers should help in fostering conceptual understanding of physics concepts in physics students using scientific explanation of phenomenon to trigger students’ scientific imagination and students’ scientific concept formation.

Influence of family background on students’ drop out from secondary schools in Yakurr local government area.

The study examined the influence of family background on students’ dropout from secondary schools in Yakurr local government area of Cross River State. The study adopted the descriptive survey design and paired t-test and independent t-test were used in analyzing the data collected. The instrument for data collection was a structured questionnaire known as the family background and students’ dropout questionnaire (FBSSDQ)made by the researcher. One hundred and fifty (150) students were randomly sampled from five (5) selected secondary schools from the study area. Fifty (50) students were used for trial testing outside the population of the study. Kuder Richardson 20 (KR20) reliability estimate was used to determine the reliability indices of the three sub variables as follows: family size = 0.78, parents’ attitude = 0.81 and parents’ socio-economic/educational status = 0.73 respectively. The results showed students do drop out from schools and that this situation is attributed to certain factors such as family size, parents’ attitude, parents’ socio-economic status and educational background. It was recommended that parents should be fully educated on population size and education, there should be a massive education campaign to enlighten the parents and the general society on alternative ways of checking school dropout and the government should not shift the whole responsibility of financing education to parents since most of the parents are financially handicap and poor.&#x0D; Keyword: family size, parents’ attitude, parents’ socio-economic status, dropout.

The population for the study was 210 National Technical Certificate (NTC II) furniture craft technology students (175 males and 35 females) in Technical Colleges. This study was carried out in Zamfara and Katsina State. The analysis was guided by three research questions and three hypotheses at 0.05 level of significance. The data were obtained with Furniture craft technology Cognitive Achievement Test (FTCAT) and Furniture craft technology Interest Inventory (FTII). The lesson plan, FTCAT, and FTII were subjected to face and content validation by three experts. The instrument was trial tested on a sample of 22 NTC II furniture craft technology students of Government Technical College FCT-Abuja. Kuder-Richardson 20(K-R20) and the Pearson product-moment correlation coefficient were utilized to establish the coefficient of internal consistency and stability of the FTCAT. The values were found to be 0.72 and 0.81 respectively. Data obtained from the administration of the instrument was examined with mean to answer the research questions and Analysis of Covariance (ANCOVA) statistic was used to test the hypotheses. The results showed that the Challenge-based learning approach is more successful in enhancing the students' achievement in furniture craft technology than the Activity-based learning approach. It was recommended that the Ministry of Education and National Board for Technical Education (NBTE) should organize workshops, seminars and in-service training for technical teachers regularly

A New Objective Health Numeracy Test for Patients with Type 2 Diabetes: Development and Evaluation of Psychometric Properties

PurposePatients with diabetes frequently need to perform certain numeric tasks such as interpreting blood glucose levels. However, there is no psychometrically sound instrument for objectively measuring diabetes-specific health numeracy. This study aimed to develop a new objective diabetes health numeracy test (DHNT) and evaluate its psychometric properties in adult patients with type 2 diabetes. MethodsAn instrument development study was conducted. Initial items were evaluated by six experts for content validity. After a pilot test, a convenience sample of 257 participants with type 2 diabetes was recruited at 2 university hospitals from May to September 2018. The structural, convergent, and criteria validity, and internal consistency of the DHNT with binary item responses were evaluated. Data were analyzed using exploratory factor analysis, Rasch analysis, tetrachoric correlation, Spearman's correlation, and the Kuder–Richardson-20 formula. ResultsExploratory factor analysis yielded a single-factor solution comprising seven items. Rasch analysis confirmed that no item did not fit with the single factor and identified that the item difficulty parameters had moderate values. The convergent and criterion validity of the instrument were demonstrated, with diabetes knowledge and subjective diabetes numeracy, respectively, as was its acceptable internal consistency, by a Kuder–Richardson-20 coefficient of .81. ConclusionThe DHNT demonstrated satisfactory psychometric properties. The instrument with moderate levels of item difficulty may have a lower cognitive burden. The developed instrument can be applied in practice to tailor the education of diabetes self-management as per the levels of health numeracy of specific patients.

Dental-related function in individuals with stroke: A confirmatory factor analysis of the dental activities test.

The dental activities test (DAT), designed to assess individuals' ability to perform oral health-related activities, was initially tested among 90 assisted living residents with normal to severely impaired cognition. This study aimed to examine the reliability (internal consistency), convergent validity, and structural validity of DAT among individuals with stroke. This study was a secondary analysis of data collected for a cross-sectional study that aimed to understand oral disease patterns among 207 individuals with stroke from three hospitals in China. Convergent validity was examined using Spearman's Correlation coefficient (rs ) for correlation between DAT scores and the assessments of physical function and cognition. Structural validity was examined using Confirmatory Factor Analysis (CFA). The DAT demonstrated good estimates for internal consistency (Kuder Richardson-20=0.85, 95% confidence of interval [CI]=0.82, 0.88), convergent validity (rs range: 0.43-0.61, all P<.001), and good structural validity with a one-factor structure. Findings supported the reliability and validity of DAT as a unidimensional construct in measuring the ability to perform oral health-related activities in persons with stroke. Further testing among different patient populations and care settings is needed to accumulate evidence and expand the use of the test.

Evaluation of the psychometric properties of the HIV Disability Questionnaire among adults living with HIV in the United Kingdom: A cross-sectional self-report measurement study.

ObjectiveTo evaluate the psychometric properties of the HIV Disability Questionnaire (HDQ) among people living with HIV (PLHIV) in London, United Kingdom (UK).MethodsThis is a cross-sectional measurement study. We recruited and administered the self-reported HDQ, seven criterion measures, and a demographic questionnaire with adults living with HIV accessing HIV care. We determined median and interquartile ranges (IQR) for disability presence, severity and episodic scores (range 0–100). We calculated Cronbach’s alpha (α) Kuder-Richardson-20 (KR-20) statistics for disability and episodic scores respectively (internal consistency reliability), smallest detectable change (SDC) for each HDQ severity item and domain (precision), and tested 36 a priori hypotheses assessing correlations between HDQ and criterion scores (construct validity).ResultsOf N = 243 participants, all were male, median age 40 years, 94% currently taking antiretroviral therapy, and 22% living with ≥2 concurrent health conditions. Median HDQ domain scores ranged from 0 (IQR: 0,7) (difficulties with day-to-day activities domain) to 27 (IQR: 14, 41) (uncertainty domain). Cronbach’s alpha for the HDQ severity scale ranged from 0.85 (95% Confidence Interval (CI): 0.80–0.90) in the cognitive domain to 0.93 (95%CI: 0.91–0.94) in the mental-emotional domain. The KR-20 statistic for the HDQ episodic scale ranged from 0.74 (95%CI: 0.66–0.83) in the cognitive domain to 0.91 (95%CI: 0.89–0.94) in the uncertainty domain. SDC ranged from 7.3–15.0 points on the HDQ severity scale for difficulties with day-to-day activities and cognitive symptoms domains, respectively. The majority of the construct validity hypotheses (n = 30/36, 83%) were confirmed.ConclusionsThe HDQ possesses internal consistency reliability and construct validity with varied precision when administered to males living with HIV in London, UK. Clinicians and researchers may use the HDQ to measure the nature and extent of disability experienced by PLHIV in the UK, and to inform HIV service provision to address the health-related challenges among PLHIV.
