Validación del instrumento: conocimientos, creencias y aceptación de la vacuna del virus del papiloma humano

Introduction: The human papilloma virus (HPV) is the leading cause of cervical cancer. Having an instrument that measures the acceptance of the HPV vaccine, as well as the factors involved in the acceptance process, is an urgent need for HPV prevention. The objective was to validate the knowledge, beliefs, and acceptance of the human papillomavirus vaccine instrument.Materials and Methods: The validation process was carried out through a descriptive, cross-sectional study and a two-phase process. The population consisted of 393 mothers of girls between the ages of 9 and 11 years, belonging to the State of Puebla, with a non-probabilistic sampling for convenience; the sample was considered at a ratio of 10: 1.Results: A valid and reliable instrument was obtained with a Cronbach's Alpha of .70, a value of p <.000 for Bartlett’s sphericity test, and .82 for the KMO test. In this sense, the factor analysis resulted in a total of 40 items divided into six dimensions.Discussion: The methodological process allowed to have an empirical indicator adapted and validated for the Mexican context, since it is the only one within the context that measures the factors related to the acceptance of the HPV vaccine.Conclusion: We conclude that having an empirical indicator adapted to the Spanish language, which measures acceptance and related factors, is a contribution of great importance to society and an advance in nursing science.

Methodology for Developing a Usability Assessment Questionnaire in Spanish as a Bilingual Strategy for Software Improvement

Usability is the characteristic of a software product of being effective and efficient and producing satisfaction for users and traditionally is assessed through questionnaires but most of them are only available in English. A software usability assessment questionnaire (SUAQ) is proposed in two languages: Spanish and English. The methodology comprises four stages: 1) questionnaire development, 2) administration, 3) statistical validation, and 4) sample size determination. Twenty items were evaluated in terms of clarity, consistency, and relevancy. Then, the SUAQ was administered to 95 respondents. Overall, reliability values were acceptable in Spanish and English version, respectively. The factor analysis was feasible since the KMO index, and the Bartlett sphericity test was statistically significant. Both versions of SUAQ were tested to determine their validity. The findings show that the proposed methodology is an effective usability assessment instrument and thus an effective software improvement tool from a bilingual approach.

Development and validation of an instrument to evaluate medical students' lifestyle

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.

What Are University Professors’ Motivations? A Realistic Approach to Self-Perception of a Group of Spanish University Professors Belonging to the G-9 Group of Universities

Universities face challenges on a number of levels. In this scenario, university professors play an important role as facilitators of knowledge. The main objective of this study was to analyse the motivations that influence the professional performance in a sample of 102 university professors from nine Spanish public universities (Male: 54 (52.9%); Female: 48 (47.1%)). For this purpose, a questionnaire of 22 closed-ended Likert-type questions was designed, in which scores ranged from 0 to 10 (do not agree at all, strongly agree). Following analysis, the final questionnaire was composed of 17 items, and showed good internal consistency (Cronbach’s alpha = 0.858). The validity analysis showed a value of 0.822 (>0.5) in the sample adequacy measure of Kaiser–Meyer–Olkin and Bartlett’s sphericity test (p < 0.0001). The exploratory factor analysis showed a clustering in four factors (two for intrinsic motivations and two for extrinsic motivations), explaining 64.33% of the total variance. Comparisons between each factor score by gender (male and female) showed statistically significant differences for factor F1 (higher for females) and F2 (higher for males). Finally, Q1 and Q13 showed a statistically significant correlation (p ≤ 0.05) with years of teaching experience. The motivations of Spanish university professors appear to be associated with the age and gender of the teacher.

What are University Professors’ Motivations? A Realistic Approach to Self-perception of Spanish University Professors’ Professional Development

Background: The university must take on the challenges that arise at all levels. Within this mechanism, university professors play an important role as facilitators of knowledge. Aim: To analyse the motivations that influence the professional performance of Spanish university professors. Methods: 102 university professors from 9 Spanish public universities participated in the study. [Male: 54 (52.9%); Female: 48 (47.1%)]. A questionnaire of 22 closed-ended Likert-type questions was designed, scoring from 0-10 (do not agree at all, strongly agree). Results: The questionnaire, finally composed of 17 items, showed good internal consistency. (Cronbach's alpha=0.858). The validity analysis showed a value of 0.822 (&gt;0.5) ) in the sample adequacy measure KMO (Kaiser-Meyer-Olkin) and Bartlett's sphericity test (p&lt;0.0001). The exploratory factor analysis showed a clustering in 4 factors (2 for internal goods and 2 for external goods), explaining 64.33% of the total variance. Comparisons between each factor scores by gender (male and female) showed differences statistically significant by gender for factor F1 (higher for females) and F2 (higher for males). Finally, Q1 and Q13 showed a statistically significant correlation (p&le;0.05) with years of teaching experience. Conclusions: The motivations of Spanish university professors seem to be associated with the age and gender of the teacher.

Development and Validation of a Food Literacy Assessment Tool for Community-Dwelling Elderly People

Food literacy refers to the knowledge, skills, and attitudes required for individuals to choose foods that promote health. As the rate of diet-related diseases increases, food literacy is becoming more important. However, there are no tools available to evaluate food literacy among the Korean elderly. We derived 547 questions from a literature review and, after three rounds of Delphi surveys, selected 33 preliminary questions. We calculated the content validity ratio of the questions and applied a face validity procedure. We then selected 32 questions, assessed their validity, and distributed them as a questionnaire to 205 elderly people. We then conducted exploratory factor analysis (EFA) to determine the validity of the questionnaire and used an internal consistency index (Cronbach’s α coefficient) to determine reliability. Based on the factor analysis, 13 questions were selected, distributed among three factors, and evaluated using the Kaiser–Meyer–Olkin (KMO) and Bartlett sphericity tests. The factor analysis showed that KMO was 0.872, which is a highly acceptable score, and the Bartlett sphericity test was χ2 = 1,374.69 at p = 0.00. The food literacy questionnaire developed in this study will likely be helpful for improving the healthcare of elderly people.

Saberes digitales en el profesorado universitario. Estudio en una escuela mexicana.

Se presenta una investigación empírica que evalúa los saberes digitales en profesores de educación superior, los datos fueron recopilados en una institución mexicana ubicada en el noroeste del país. La muestra es probabilística aleatoria simple compuesta por 224 profesores clasificados desde las variables Edad, Grado académico y Género, ya que, se trabajó con el hipotético de que los conocimientos tecnológicos están relacionados con estos factores. Con la finalidad de buscar relación estadística en el agrupamiento de los datos, se realizó un factorial exploratorio por Kaiser-Meyer-Olkin (KMO) y prueba de esfericidad de Bartlett con el método de extracción de componentes principales y rotación varimax. Se aceptaron solo los factores con un autovalor superior a 1 y un peso factorial por ítem superior al 0.40. Posteriormente se realizaron pruebas estadísticas no paramétricas para identificar relaciones desde las variables de cruce. Los hallazgos dan cuenta de que la Edad de los profesores es un factor diferenciador para la apropiación de saberes digitales. An empirical research is presented that assesses digital knowledge in higher education teachers, the data was collected in a Mexican institution located in the northwest of the country. The sample is simple random probabilistic composed of 224 teachers classified according to the variables Age, Academic Degree and Gender, since the hypothetical was worked on that technological knowledge is related to these factors. In order to find a statistical relationship in the grouping of data, an exploratory factorial was performed by Kaiser-Meyer-Olkin (KMO) and Bartlett's sphericity test with the principal component extraction method and varimax rotation. Only factors with an eigenvalue greater than 1 and a factorial weight per item greater than 0.40 were accepted. Subsequently, non-parametric statistical tests were performed to identify relationships from the crossover variables. The findings show that the age of the teachers is a differentiating factor for the appropriation of digital knowledge.

Investigate the improvement of facial skin texture with the VISIA system after total thyroidectomy

Background During clinical practice we have noticed that some patients with hyperthyroidism have finer skin with less wrinkles, pores, and spots after thyroidectomy, and the improvement can be observed within a few weeks after the operation. However, there is no evidence or study in the literature to proof this finding. Aim and objective This study was designed to evaluate and quantify the skin characters of patients with hyperthyroidism before and after thyroidectomy. Material and methods This is a prospective study to include patients with hyperthyroidism who received total thyroidectomy between March 1st, 2018 and February 28th, 2019. The patients received blood test for T4 and TSH analysis and VISIA measurements for skin texture quantification, at the preoperative stage, three, and six months postoperatively. A total of 8 patients were included. Repeated measurement was used to determine the lab data and VISIA measurement changes before and after the operation. Mauchly’s sphericity test was performed to determine whether the violation of sphericity occurs, and the Greenhouse–Geisser correction was used when the violation of sphericity occurs. Results All the patients were female and generally healthy without systemic medical disease except the hyperthyroidism. The T4 and TSH levels were not significantly different before and after the thyroidectomy. In terms of the skin character measurements, the wrinkles, texture, pores, UV spots, and brown spots were not improved after thyroidectomy. A trend of improvement in spots, red area, and porphyrin was noted, although not statistically significant. Conclusions Surgical removal of the thyroid gland in patients with hyperthyroidism does not improve the skin quality and texture in examinations via the VISIA system.
