Understanding attitudes toward science and measuring them remain two major challenges for science teaching. This article reviews the concept of attitudes toward science and their measurement. It subsequently analyzes the psychometric properties of the "Test of Science-Related Attitudes" (TOSRA), such as its construct validity, its discriminant and concurrent validity, and its reliability. The evidence presented suggests that TOSRA, in its Spanish-adapted version, has adequate construct validity regarding its theoretical referents, as well as good indexes of reliability. In addition, it determines the attitudes toward science of secondary school students in Santiago de Chile (n = 664) and analyzes the sex variable as a differentiating factor in such attitudes. The analysis by sex revealed low-relevance gender difference. The results are contrasted with those obtained in English-speaking countries. This TOSRA sample showed good psychometric parameters for measuring and evaluating attitudes toward science, which can be used in classrooms of Spanish-speaking countries or with immigrant populations with limited English proficiency.

Background/aim: Literature has systematically established that forgiveness has therapeutic effects. As for this, measures of forgiveness are a scientific and practice need. A study was designed to validate in Spanish setting the gold standard for the measure of forgiveness, the Enright Forgiveness Inventory-30 (EFI-30). Method: The EFI-30 was translated to Spanish from the original English version (back translation). The EFI-30, a measure of forgiveness and a measure of social desirability were administered to a Spanish sample of 623 participants (66.8 % female, 32.4% male, 0.8% did not report) with a mean age of 29 years (SD = 14.65). Results: A confirmatory factorial analysis showed the best fit indexes (construct validity) for the seminal 6-factor structure (positive affect, negative affect, positive behavior, negative behavior, positive cognition, negative cognition) of the EFI-30 (factorial invariance), a positive correlation with the measure of forgiveness (convergent validity), and a non-significant correlation with social desirability (discriminant validity). Likewise, through the mean variance extracted, convergent validity was also found for the factors and discriminant validity between the factors. The reliability of the composite was α = .96. Conclusions: The results of the validation of the EFI-30 in Spanish are discussed, as well as the validity of its use in scientific studies (α > .80) and in applied settings (e.g., clinician) involving important decision making (α > .95).

For the sake of prevention in high conflict families in process of separation or divorce who resolve situations by only attending court, and since there is no instrument to identify this trend, this paper aims to create a questionnaire for measuring characteristics predicting judicialization. This paper focuses on C-JUDIFA questionnaire's content and internal validity, confirming that the items used accurately describe the characteristics to be measured while obtaining a good representativeness of the proposed scales. Factor analysis supports the three-factor structure theoretically proposed, while finding a strong correlation between all 9 suggested constructs. Likewise, further research is needed in order to analyze the relationship of all these factors in the judicialization tendency through the research of external validity. [ABSTRACT FROM AUTHOR]

Statistics anxiety is defined as a set of emotional reactions that generate discomfort in the students, such as excessive worry, intrusive ideas and tension when they attending a course that involves statistics or statistical analysis. For its measurement, different instruments have been designed; the most used is the Statistical Anxiety Rating Scale (STARS). The objective of the present study was to adapt and validate the STARS in a Colombian sample to explore its psychometric properties. A total of 357 university students with ages between 18 and 36 years participated (X = 19.19, D.E. = 1.87). The results show that the subscales of the STARS show excellent levels of reliability; factor analysis confirms the sixdimensional structure and important concurrent validity is reported. It is recommended for research and as a tool for decision making in academic support processes in universities. [ABSTRACT FROM AUTHOR]

The main aim of this study is to analyze the psychometric properties of the Adolescent Sexism Detection Scale in Castilla-La Mancha region, Spain. This research uses a quantitative methodological strategy and a transversal design. The sample, based on a two-stage sampling in 60 educational centers, is consists of 1840 secondary school students (50,1% women and 49,9% men). Factor analysis reports good psychometric properties for a correlated twodimensional structure. Fit indices are acceptable: X2/gl = 4,17, GFI = 0,91, IFI = 0,92, TLI = 0,91, CFI = 0,92, SRMR = 0,05, RMSEA = 0,06, AIC = 1145,07. These dimensions coincide with the forms of ambivalent sexism: hostile and benevolent sexism. Reliability of scale and subscales is adequate (α > 0,80). Negative correlations between the Adolescent Sexism Detection Scale and the Students' Attitudes towards Equality Scale confirm discriminant validity. Therefore, the ASD is valid and reliable in adolescents from Castilla-La Mancha. [ABSTRACT FROM AUTHOR]

Background: Insomnia can harm daily functioning and is strongly associated with depression and anxiety symptoms, especially in women. El Salvador has no scales with adequate psychometric properties for their measurement. In this context, the Athens Insomnia Scale (AIS) is a viable option to measure this symptomatology, given its short length of time, solid theoretical foundation, and relevance in other countries. Objective: To analyze the psychometric properties of AIS in the Salvadoran population, in its complete (AIS-8) and abbreviated (AIS-5) versions. Method: The study consisted of 1479 Salvadoran adults from the 14 departments of the country (mean age = 33.3 years, SD = 11.7) who were screened through a non-probability sampling design. Evidence of reliability, validity based on internal structure, and convergent validity were examined. Results: Both scales showed adequate internal consistency, validity based on internal structure through a one-factor structure, invariance between sexes, and convergent validity with depression, anxiety, and stress scales. Conclusions: Both versions have adequate psychometric properties. Shared covariances and partial mismatch indexes suggest the need to analyze its cultural adequacy. Despite this, there is sufficient evidence to support its usefulness in evaluating symptoms of non-organic insomnia in the Salvadoran population. [ABSTRACT FROM AUTHOR]

Adapting by making meaning of adverse life situations such as unavoidable losses and other stressful events throughout life is crucial for people to maintain their physical and mental well-being. Holland et al. (2010, 2014) created and validated two versions -long and short- of a scale to assess the degree of adaptation of an individual to a loss or a stressful event. To adapt and validate the Integration of Stressful Life Experiences Scale-Short Form (ISLES-SF) to Mexican Spanish, an instrumental study was carried out. In the exploratory factorial analysis, the sample consisted of 227 participants (M = 19.51, SD = 1.67) and in the confirmatory factorial analysis, 550 participated (M = 19.86, SD = 3.38). Each factorial analysis corroborated the bifactorial structure, with a good fit of the model, satisfactory internal reliability, and good construct and instrumental validity, like the original scale validations.

A number of factors are associated with students' reading habit, and family and school environments are among the most important contexts for the socialization of reading. The focus of this study is to determine the psychometric properties of a questionnaire to identify the main variables that support the adoption of a reading habit in primary education, analyze reading behavior based on books read, and corroborate the predictive model for reading behavior using a linear regression model. Based on a non-experimental, crosssectional quantitative approach, the instrument was validated by analyzing data from 403 primary education students from the region of Murcia (Spain), and the construct validity was determined through factor analysis and by validating its consistency and reliability. The results obtained indicate that the instrument constructed has consistent psychometric indicators for the purpose it aims to serve. [ABSTRACT FROM AUTHOR]

The importance of ICT in Higher Education is present in international and national policies; in contextual moments where distance and asynchronous education is prioritized, it is urgent to identify the competences in university students. This research sought to validate in the Mexican population a scale to evaluate the frequency of use and function of ICTs and the educational contexts in which they are used, that supports knowledge about their strengths and areas of opportunity. The methodology was quantitative and divided into two phases: 1) descriptive study to design and pilot the scale; and 2) validation of the final version of the instrument with 390 students from three states of the country. From the analysis of descriptive studies, normality, construct validity (factor analysis) and reliability, the instrument was make up of two components: a) 26 items distributed in 4 factors that measure frequency of use and function; and b) 8 multiple - choice items to identify educational contexts of use. This scale explained 42.7% of the variance, with a global Cronbach Alpha of .91. The use of reliable assessment tools in higher education, will facilitate the intervention and the development of psycho - educational strategies for the acquisition of ICT skills.

The main purpose of this study is to report the construct validity and internal consistency of the Peruvian Inventory of Mindfulness and Equanimity. Based on the factor analysis and the Item response Theory (the Partial Credit Model and the Mokken Scale Analysis), the parameters magnitude was examined, and we estimated the variance of each item of the instrument that contribute to the general construct of mindfulness. The analyses were carried out on a sample of 602 adults, students from three educational institutions at the university level in the cities of Lima, Chiclayo, and Chimbote in Peru. The results of all the analyses performed on this peruvian sample suggest a unidimensional structure of this inventory, based on the eight items selected that include the abilities of attention, consciousness, acceptance, judgment, and equanimity. The goodness of fit index and adjusted goodness of fit index for the oblique factors were satisfactory: cfi = .982, rmse a = .043 (ic90% = .029, .056), sr mr = .048, sb-?2 (gl: 35) = 73.415 (p > 0.05).

Introduction: Academic engagement refers to the predisposition that students must actively participate in university life, attending classes, turning in work on time, and following teachers' instructions. There is evidence that shows that academic engagement positively predicts student success. For this reason, its evaluation is of great relevance for university education when designing pedagogical practices that stimulate student engagement. The aim of this study was to adapt and validate the University Student Engagement Inventory (USEI) into Spanish, considering linguistic and cultural differences in three Spanish-speaking countries. Methods: 921 university students from Spain, Argentina and Uruguay participated in the study. The USEI, which consists of 15 statements grouped into three dimensions of engagement -behavioral, cognitive, emotional-was administered. Results: After three translators made the linguistic adaptation of the instrument, nine expert judges analyzed the content of the items, retaining as a result the totality of the items. Subsequently, the internal structure of the instrument was analyzed and verified -confirmatory factor analysis, cross-validation, factorial invariance, internal consistency-. Adequate evidence of concurrent external validity between USEI dimensions and learning approaches was also obtained. Conclusion: A Spanish version of the USEI was obtained with adequate psychometric properties that can be used in the field of application with the purpose of identifying students' academic engagement and proposing actions aimed at improving their learnings.

The present study shows an exploratory experience of validation of an instrument for measuring the level of financial culture in the Millennial Generation. The instrument was developed based on 25 items in accordance with the Likert Scale, aimed at university students in the last year of the degree and recent graduates. Through the validity of content by 16 expert judges and the factor analysis, an exploratory exercise of content validity was achieved, allowing an analysis of each of the items to be established based on the level of financial culture. The degree of reliability of the instrument obtained through Cronbach's Alpha, showed a statistic of (0.681), so it is established that it has a level (0.592) of reliability, which means that the content of the instrument can be used for data collection.

Background: Students' attributions of their grades may affect their academic performance. However, lack of evidence supporting the validity and reliability of the instruments measuring attribution is a major concern. Objective: To analyze the factor structure, convergent validity and reliability of the Academic Attributional Style Questionnaire adapted to Mexican high school students (EAT-A). Method: The sample consisted of 557 Mexico City students of both sexes aged between 15 and 19. Using a confirmatory factor analysis for both success and failure attributions, a 7-factor structure and a 4-factor structure of the EAT-A were tested. The instrument's convergent validity, internal consistency and reliability were examined. Results: Only the 7-factor structure showed adequate fit indices: RMSEA = .046; SRMR = .053; CFI = .961; TLI = .952 and X²/gl = 2.72. In addition, the EAT-A evidenced convergent validity concerning success and reliability motivation. Conclusion: The EAT-A is a quick- and easy-to-administer instrument for measuring students' attributions of their grades in a reliable and valid manner. [ABSTRACT FROM AUTHOR]

This article aims to present the methodology that was designed for the development of research competences from the educational approach of socioformation, which includes an evaluation instrument to measure the impact of these on the pedagogy students, who, every four months, develop a research project in a group form. However, the absence of methodological knowledge and content were identified because they did not carry out the necessary collaboration to comply with each project. In addition, the teachers had no idea of what competences to develop or how to evaluate them for a better group performance. For this, an investigation was initiated in two stages: in first, a documentary analysis was carried out based on certain categories of analysis that led to the identification of competences, didactic strategies, and the type of evaluation that will be used. In the second one, an analytical rubric was designed with five levels of competence, under the supervision of expert judges, which was applied to a pilot group, as well as to a sample of 250 graduate students due to the lack of university students who were carrying out research projects. And, finally, to two groups of 50 students each, of the degree to establish a comparison according to the frequency of the results and confirm the validity of the evaluation instrument. For its analysis, Cronbach's alpha was used to measure its internal consistency, the V of Aiken for the validity of the content, and a factorial analysis through the factorization extraction method of the main axes. The results show that the evaluation instrument measures the research competences in accordance with the theoretical foundations of socioformation. [ABSTRACT FROM AUTHOR]

Introduction: The Orientation to Life questionnaire measures the sense of coherence, a concept related to the use of coping resources that have a positive influence leading to a better quality of life and sense of well-being for adults with cardiovascular disease. Objective: To determine the validity and reliability of Antonovsky's Orientation to Life questionnaire in adults with arterial hypertension. Method: Methodological study in which cultural adaptation was carried out and the reliability and face, content, and construct validity were determined. In the cultural adaptation, a process of translation, consensus, and back-translation was followed. Content and face validity were met by expert judgment, using the Fleiss' kappa coefficient and modified Lawshe index statistical tests. Two hundred and twenty people participated in the construct validity and reliability test. Reliability was calculated using the Cronbach's alpha statistical test. Results: In terms of face validity, the instrument reported a Fleiss kappa index greater than 0.41, interpreted as moderate agreement. The content validity index was satisfactory with 0.87; the exploratory factor analysis reported three factors with a total explained variance of 36.21%. Cronbach's alpha was 0.82 for the full scale. Conclusions: The Spanish version of the Orientation to Life instrument presents an adequate content validity and reliability index for use in the local context. It is necessary to continue its application in other groups and times to continue refining its validity. [ABSTRACT FROM AUTHOR]

Bruxism is defined as a repetitive jaw-muscle activity, characterized by grinding or clenching the teeth, and/or by bracing or thrusting of the mandible, which has different circadian manifestations, either during sleep (sleep bruxism) or when wakefulness (awake bruxism). For an appropriate clinical diagnosis of bruxism different techniques have been proposed; the most common technique is the usage of a self-reported questionnaire combined with a professional evaluation. While the first is a questionnaire in which the patient expresses their symptoms, the second depends on the presence of observed signs associated according to an evaluator, including tooth wear as well as identify symptoms associated to this jaw-muscle activity, to confirm a clinical diagnosis, there must be a correlation between the self-report questionnaire and clinical diagnosis. Therefore, there is no quantifiable measure that may help to evaluate, from a patient's perspective, the signs and symptoms that belongs to his/her muscle and mandibular activity while assessing both its proportion and measure. To strengthen the self-report technique as a reliable procedure for assessing the information expressed by patient with bruxism, this initial study reports the reliability and validity proprieties of the self-report bruxism questionnaire (CBA). The present study was conducted in Mexico and includes one hundred participants. Fifty percent of them presented a clinical diagnosis of bruxism (n = 50), the other half (control group) do not. In both groups the perceived stress scale (PSS) and the self-reported bruxism questionnaires (CBA) were equally completed on a self-administered way. Both a high internal consistency (a = .884) was found on the eleven items and a corrected item-total correlation ranged from .43 to .78, reflects an adequate reliability. The exploratory factor analysis was used to group the CBA variables; the extraction was made using a main component with Varimax rotation method. The sample adequacy coefficients, the Kaiser Meyer-Olkin (KMO = .826) and Bartlett's Sphericity test (X2 = 579.866, p = .000) were assessed and expressed an appropriate intercorrelation between items. The factor analysis showed a bifactorial: the latent variables explained one factor of 47.8% (eigenvalue = 5.26) variance and another of 11.5% (eigenvalue = 1.27), thus its cumulative variance of this model was 59.36%. Due to the amount of explained variance and the difference between the eigen values of this initial solution we considered to prove a unidimensional model. A one solution factor scale was feasible, with factor weights greater than .52 on all items. This singlefactor structure was verified in a confirmatory factor analysis, which presented significant values and suitable goodness of fit indexes (X²/df = 1.461; GFI = .916; AGFI = .857, CFI = .967, RMSEA = .068). Also, a convergent analysis was performed proving a positive (r = .27; p = .001) correlation between the PSS-14 and CBA scales, the correlation with the subscales of self-reported awake bruxism, SAB was positive (r = .299, p = .002). Regarding self-reported sleep bruxism, SAB the correlation was also positive (r = .207, p = .039). The correlation between the subscales was both positive and strong (r = .713, p = .001). Based on the results obtained, we can conclude that, there are a positive, significant, and adequate correlation between PSS-14 scale and the scale of self-reported bruxism, as though as in the sub-scales SAB and SSB. These results suggested that the one factor solution of the CBA has high reliability, internal consistency, and an appropriate inter-item correlation; also, it supports the convergent validity of the questionnaire. Due to the possible contributions of the CBA to the improvement of the quality standards of the evaluation of subjective data provided by people with bruxism, it is suggested to continue with the analysis of the scale in future studies with other populations.

The aim of this study is to obtain psychometric data for the evaluation of dissatisfaction with body image Questionnaire (Solano-Pinto y Cano-Vindel, 2010). A total of 411 Mexican university students participated (average of age = 20.65 ± 1.92 years) in this study. The factor structure of the questionnaire was analyzed trough exploratory and confirmatory factor analyses. Results showed a feasible and adequate structure of five factors (perceptual, emotional distress, behavioral, approach change and anxiety), with adequate fit indices of reliability and validity, according to statistical and substantive criteria. However, the obtained model does not fully coincide with that propose by the authors of the test, but continues giving support to the multifactorial component of body dissatisfaction. Future research should replicate these findings in wider samples. [ABSTRACT FROM AUTHOR]

The instruments used to assess quality of life are useful tools that should provide real, safe and adequate information to promote programs, diagnose situations, to evaluate treatments, among others. Therefore must follow psychometric validity and reliability processes that allow its use in the local context, showing that measures what it purports to measure with a high degree of accuracy. Objective: To determine the validity and reliability of the Betty Ferrell's quality of life instrument, for people with Chronic disease, for Colombian context, by conducting psychometric tests. Methods: Descriptive study of cross-sectional quantitative approach. It was conducted; facial, content and construct validity was made, reliability for internal consistency using Cronbach's alpha. Results: The instrument adequate content validity with 0.9, internal consistency using Cronbach's alpha was 0.88, it was adequate. Regarding construct validity: factorial analysis only 22 of the 41 items are explained by the underlying dimension factor raised by the author, showing marked discrepancy in the dimensions of Psychological and Social Welfare. Conclusions: The quality of life instrument Betty Ferrell for people with chronic disease requires further study construct validity, it is recommended to delete items and perform a confirmatory factor analysis.

The study of work engagement is becoming increasingly common in the scientific literature. There are many inconsistencies regarding the factorial structure of the Utrecht Work Engagement Scale (UWES) the most widely used instrument by researchers in different countries. The objective of this study is to examine the psychometric properties of the UWES using a sample of 2,796 employees in Puerto Rico. We examined the psychometric properties of UWES using structural equations with the method of maximum likelihood estimation. The results show that the three-factor model has a better fit, being consistent with the conception of engagement as a construct formed by three dimensions: vigor, dedication, and absorption. The validity and reliability of UWES are appropriate, and we conclude that the scale has the qualities to be used in research in the Puerto Rican labor context. [ABSTRACT FROM AUTHOR]
