RESUMEN

Occupational self-efficacy has gained attention because of its importance in understanding the effects of psychosocial factors at work, but because of its relevance, it is necessary to study it in the context of the COVID-19 pandemic. The Occupational Self-Efficacy Short Scale Form (OSS-SF) is a measure of individual variability in self-efficacy within the work context and has been used in some studies in Latin America. The aim of this study was to obtain evidence of the validity of the OSS-SF for 214 Peruvian teachers and to evaluate its internal structure and associations with other constructs. The sample, composed of 214 teachers (Mage = 44, SDage = 10), was selected using nonprobabilistic convenience sampling and evaluated via online forms. Nonparametric item response theory was used. Among the results, a unidimensional structure and high scalability at the item and scale levels were obtained (>0.70). The reliability was approximately 0.90. There was moderate convergence with job satisfaction (0.39) and slight convergence with the perception of the management of virtual tools (0.18). The OSS-SF is a scale with adequate evidence of validity and reliability for Peruvian teachers who work remotely. Therefore, it can be used as a diagnostic measure of intervention and training needs to benefit teachers and students.

RESUMEN

The abbreviated measurement of coping strategies is useful for monitoring and identifying the effects of stress. The Coping strategy indicator-Short version (CSI-S, including the dimensions of seeking support, problem solving and avoidance strategies) is a new adaptation of the full version of this indicator, and additional evidence of its validity is needed. Psychology students (n = 125) from a public university in Lima, Peru, were recruited to help provide such evidence of validity in terms of internal structure, reliability and associations with other variables (perceived stress and general efficacy in cope with difficulties), which were evaluated using nonparametric item response theory procedures. Support-seeking and problem-solving items from the Mokken scale and the avoidance scale exhibited limitations. The correlations between the scales were moderate or low and exhibited theoretical consistency, and the relationship with perceived stress highlighted the predictive capacity of avoidance and problem-solving strategies. In general, the CSI-S exhibits suitable psychometric properties; however, the avoidance score requires further examination or reconstruction of its items.

RESUMEN

Resumo Objetivo: identificar a associação entre percepção de risco e vários efeitos psicológicos negativos e positivos, bem como o efeito moderador do apoio social, em uma amostra de trabalhadores de saúde com pacientes com COVID-19 no México. Métodos: trata-se de um desenho ex-post-facto e instrumental. As respostas foram obtidas por meio de questionário on-line , utilizando a estratégia de bola de neve. A associação entre percepção de risco e vários resultados psicológicos foi examinada por meio de correlações monotônicas (Spearman, rs), e um modelo de regressão foi estimado para cada efeito psicológico a fim de testar o efeito moderador do apoio social. Resultados: participaram 269 trabalhadores da saúde, sendo 75,5% mulheres. Os achados mostram a percepção de risco com uma tendência elevada, especialmente em relação ao "risco de dano grave pelo SARS-CoV-2". O apoio social apresentou uma tendência de moderada a alta, e os sintomas negativos de saúde mental tiveram uma tendência abaixo das médias teóricas. Conclusão: o apoio social desempenha papel moderador na magnitude da associação entre a percepção de risco e os efeitos psicológicos. Apesar das limitações reconhecidas, este trabalho visa ajudar a explicar os mecanismos complexos das variáveis em estudo por meio da análise exploratória de interações.

Abstract Objective: to identify the association between risk perception and various negative and positive psychological effects, as well as the moderating effect of social support, in a sample of health care workers with COVID-19 patients in Mexico. Methods: this study has an ex post facto and instrumental design. Responses were obtained by means of an online survey using snowball convenience sampling. The association of risk perception with various psychological outcomes was examined using monotonic correlations (Spearman, rs), and a regression model was estimated for each psychological effect to test the moderating effect of social support. Results: a total of 269 health care workers took part, 75.5% of them women. The findings show that risk perception tended to be high, especially in relation to the "risk of serious harm from SARS-CoV-2". Social support had a moderate to high trend, and negative mental health symptoms had a trend below theoretical average points. Conclusion: social support plays a moderating role in the magnitude of the association between risk perception and psychological effects. Despite the acknowledged limitations, this work aimed to help explain the complex mechanisms of the study variables by analyzing exploratory interactions.

RESUMEN

The areas of work life scale (AWS) has shown to be a suitable marker of perceived fit between employees' abilities and the psychosocial demands of the job, but validation studies are practically nonexistent in the Latino population. The purpose of this study was twofold: firstly, to examine the factor structure, reliability, and invariance between sex and occupation of the AWS scale, and secondly, to test the AWS-burnout relationship within the framework of the structural mediational model proposed by Leiter and Maslach (2005). N = 305 health workers and N = 324 teachers from different work settings answered the AWS and MBI-GS scales. In this study, 64.4% of the participants were females (N = 405), and the mean age was 34.7 (sd = 11.7, rank = 56). Robust methods for statistical analyses were used. The results showed that the original version had marginal fit indices due to a method effect (negative phrasing items), and when seven negative items were removed, a final best model was found (CFI = 0.997; RMSEA = 0.060; SRMRu = 0.047). Non-invariance between occupation and sex was found, and the internal consistency was from marginal to satisfactory (ω = 0.658 to 0.840). The mediational structural model tested confirmed the expected associations between AWS and burnout. In conclusion, the Mexican translation of the AWS in its 22-reduced version showed reliability and validity in Mexican work contexts, specifically in healthcare workers and teachers.

RESUMEN

Mental health is currently a public health issue worldwide. However, evidence is lacking regarding the validity of the instruments used to measure and assess positive mental health in specific populations. The objective of this study was to evaluate the psychometric properties of the PMHS using IRT. A cross-sectional retrospective study with non-probabilistic convenience sampling was conducted with 623 parents of children undergoing cancer treatment at the National Institute of Health in Mexico City. The participants responded to a battery of tests, including a sociodemographic questionnaire, the PMHS, Measurement Scale of Resilience, Beck Depression Inventory, Inventory of Quality of Life, Beck Anxiety Inventory, an interview regarding caregiver burden, and the World Health Organization Well-Being Index. PMHS responses were analyzed using Samejima's graded response model. The PMHS findings indicated that the IRT-based graded response model validated the single latent trait model. The scale scores were independent of depression, anxiety, well-being, caregiver burden, quality of life, and resilience. The PMHS scores were associated with low subjective well-being. The PMHS findings reveal that from an IRT-based perspective, this scale is unidimensional and is a valid, reliable, and culturally relevant instrument for assessing positive mental health in parents of children with chronic diseases.

Abstract: Objective: When two independent groups of expert judges study content validity, a formal test of the differences between their judgments is required, since different content validity judgments can be obtained. But generally, content validity research does not examine this likely source of discrepancies. This report describes the implementation of a method to evaluate the difference in Aiken's V coefficients applied to research work in sports science. Methodology: The procedure applies an adaptation to construct the confidence interval of the difference between Aiken's V coefficients and also implements a standardized estimator of the size of the difference between the V coefficients, specifically the arcsine transformation of V coefficients. Results: In a secondary data analysis framework, two examples are developed, extracting data from both publications, and the difference between the impressionist-based conclusion and the empirical-based conclusion and formal evaluation is demonstrated. Statistical differences not previously observed were detected. Conclusions and implications: The method to estimate differences in Aiken's content validity coefficients for research allows an advance in the methodology to validate measurement instruments. The applicability of this procedure in the context of sports sciences and education sciences, as well as in the research design involved, is assessed.

RESUMEN

Background: This study aimed to examine the internal structure and assess the psychometric properties of the Patient Health Questionnaire (PHQ-9) in a Puerto Rican sample of workers. This instrument is a nine-item questionnaire, which was conceptualized as a unidimensional structure; however, there are mixed results regarding this internal structure. This measure is used in the occupational health psychology context in organizations in Puerto Rico; nevertheless, there is little evidence of its psychometric properties with samples of workers. Materials and methods: A total of 955 samples from two different study samples were used in this cross-sectional study design in which the PHQ-9 was used. We conducted confirmatory factor analysis, bifactor analysis, and random intercept item factor analysis to examine the internal structure of the PHQ-9. Moreover, a two-factor model was examined by randomly assigning items to the two factors. Measurement invariance across sex and the relationship with other constructs were examined. Results: The best-fitted model was the bifactor model followed by the random intercept item factor. The five sets of two-factor models with items randomly assigned obtained acceptable and similar fit indices regardless of the items. Conclusion: The results suggest that the PHQ-9 appears to be a reliable and valid instrument to measure depression. The more parsimonious interpretation of its scores, for now, is a unidimensional structure. Comparison across sex appears to be useful in occupational health psychology research settings since the results suggest that the PHQ-9 is invariant regarding this variable.

RESUMEN

This study evaluates the psychometric properties of the Access of Older Adults to Outpatient Primary-Care Health Services Scale (AOAOPHSS), in research conducted among 707 Mexican older adults selected by convenience from 14 rural and one urban locations. The AOAOPHSS explores 10 dimensions of two integrated subscales: Accessibility and Personal Abilities. Data analysis was performed in five phases. First, potentially biased responses were identified. Second, the response efficiency of the items and their association with external variables were evaluated. Third, the basic properties of the scores for the subscales' dimensions of the AOAOPHSS were identified using non-parametric Mokken Scaling Analysis (MSA). Fourth, the Structural Equation Modeling methodology was used to identify the properties of the internal structure of the latent construct. Finally, reliability and internal consistency were evaluated at both score and item levels. The following findings emerged. 13 items with inefficient response options were removed, and 24 were retained using the MSA. The latent structure of the latter was defined based on 21 items of five Accessibility Subscale dimensions. Its internal consistency reliability ranged between 0.67 and 0.81 (omega coefficients) and between 0.61 and 0.78 (alpha coefficients). Accordingly, this paper discusses the overall implications of using the Accessibility Subscale.

RESUMEN

The interference between family and work roles has led to the development of scales for their measurement. However, instrumental studies of work-family conflict have not been conducted in the context of teacher teleworking during the COVID-19 pandemic. For this reason, the objectives of this study were set to obtain evidence of the internal structure and fairness of the Blanch and Aluja Work-Family Conflict Questionnaire, as well as its association with job satisfaction and other sociodemographic variables. A total of 235 Peruvian school teachers between the ages of 24 and 72 years (M = 43.79 and SD = 9.67) responded to the scale using the online form. The analysis employed the non-parametric item response theory modeling (Mokken scaling analysis). The structure of two correlated factors was confirmed: work conflict in the family (WCF) and family conflict in the work (FCW). Both dimensions were invariant with respect to sex group and educational level. The association of both dimensions with job satisfaction was theoretically convergent, and the gender of the teachers slightly moderated this relationship. The reliability was adequate for group research. Finally, the instrument can be useful in the organizational context of teachers who telework.

RESUMEN

Our objective was to analyze the measurement invariance of the Academic Situations Specific Perceived Self-Efficacy Scale (ASSPSES) among Peruvian, Mexican, Colombian, Argentinean, and Brazilian college students, and its relationship with academic emotional exhaustion (AEE). In addition to the ASSPSES, the Emotional Exhaustion Scale (EES) was used. Two thousand one hundred forty-two college students (70.26% women) between the ages of 16 and 35 (M = 21.79 years) participated. The one-dimensional structure of ASSPSES was corroborated in each sample with a confirmatory factor analysis and the measurement invariance analysis was carried out with a multi-group factor analysis (MGFA) and with the differential item functioning. The relationship with the AEE was tested with the Pearson correlation coefficient. Regard the results, in all of the samples, the one-dimensional model presented adequate psychometric indicators with respect to both dimensionality and reliability. Similarly, regarding the analysis of measurement invariance, a strong variance was attained, and DIF is weak, which together with the MGFA results provides favorable evidence of measurement invariance. We conclude that ASSPSES is an invariant measure among the analyzed groups although replicating the study is necessary for the consolidation of the findings. These findings contribute to the understanding of the internal structure of the ASSPSES, something that had been awaiting evaluation, given how the scale is used in various contexts.

El objetivo fue analizar la invarianza de medición de la Escala de Autoeficacia Percibida Específica para Situaciones Académicas (EAPESA) entre estudiantes universitarios peruanos, mexicanos, colombianos, argentinos y brasileños, y su relación con el agotamiento emocional académico (AEA). Además de la EAPESA, se usó la Escala de Cansancio Emocional (ECE). Participaron 2142 estudiantes universitarios (70.26 % mujeres) entre los 16 y 35 años (M = 21.79). La estructura unidimensional de la EAPESA se corroboró en cada muestra con un análisis factorial confirmatorio, y la invarianza de medición se llevó a cabo con un análisis factorial de grupo múltiple (AFGM) y con el funcionamiento diferencial de los ítems (FDI). La relación con el AEA se evaluó con el coeficiente de correlación de Pearson. Respecto a los resultados, en todas las muestras el modelo unidimensional presentó adecuados indicadores psicométricos, tanto en lo que respecta a su dimensionalidad como en cuanto a su confiabilidad. Del mismo modo, en cuanto al análisis de invarianza de medición, se alcanza la invarianza fuerte, y el FDI es débil, lo que junto con el AFGM brinda evidencia favorable de invarianza de medición. Se concluye que la EAPESA es una medida invariante entre los grupos analizados, aunque es necesario replicar la investigación para consolidar los hallazgos. Estos resultados contribuyen a entender la estructura interna de la EAPESA, algo que estaba aguardando una valoración, ya que dicha escala es usada en varios contextos.

RESUMEN

The objective of this work was to validate the content of a scale formulated in Spanish for older adults in Mexico, with the aim of comprehensively measuring the access of this population group to outpatient primary-care services. To this end, we carried out a methodological content-validity study in four stages: (1) construction of the scale; (2) evaluation of item legibility; (3) quantitative content evaluation by two groups of judges selected by convenience: participant-judges including older adults with adequate reading comprehension, surveyed in person (n = 23), and expert-judges comprised of researchers specialized in the fields of health services, psychometrics and aging, surveyed online (n = 7); and (4) collection of qualitative feedback from several of the participant-judges (older adults, n = 4). The content was validated both by sequentially examining the level of consensus in the responses of both groups of judges, using the Tastle and Wierman method, and by calculating Aiken's Validity Coefficient with a 90% confidence interval. The scale contained 65 items pertaining to 10 dimensions of two major constructs: accessibility (n = 39) and personal abilities (n = 26). Five items were eliminated in accordance with the minimum-consensus criterion (0.5). This is the first psychometric scale to be developed in Mexico with the view of integrating the characteristics of health-care services and the abilities of the older adults in a single questionnaire designed to measure the access of this population group to outpatient primary-care services.

RESUMEN

There is evidence in the literature that anonymity when investigating individual variables could increase the objectivity of the measurement of some psychosocial constructs. However, there is a significant gap in the literature on the theoretical and methodological usefulness of simultaneously assessing the same measurement instrument across two groups, with one group remaining anonymous and a second group revealing identities using names. Therefore, the aim of this study was to compare the psychometric characteristics of a measure of depressive symptoms in two groups of adolescents as a consequence of identification or anonymity at the time of answering the measuring instrument. The participants were 189 adolescents from Metropolitan Lima; classrooms were randomly assigned to the identified group (n = 89; application requesting to write one's own name) or to the anonymous group (n = 100; application under usual conditions), who responded to the Childhood Depression Inventory, short version (CDI-S). Univariate characteristics (mean, dispersion, distribution), dimensionality, reliability, and measurement invariance were analyzed. Specific results in each of the statistical and psychometric aspects evaluated indicated strong psychometric similarity. The practical and ethical implications of the present results for professional and research activity are discussed.

RESUMEN

The study of the dimensionality or internal structure of a measure has a definitional purpose with notable theoretical and practical implications; this aspect can be analyzed via both parametric and nonparametric approaches. The latter are probably used less often to validate constructs in the context of psychosocial work factors. The aim of the present manuscript was to employ both nonparametric (DETECT and AISP-Mokken) and parametric (semiconfirmatory factor analysis) procedures to analyze the internal structure of the Psychosocial Work Processes Questionnaire (PROPSIT) in the context of two samples of Peruvian workers located in the city of Lima, Perú, with one sample drawn from various work centers (n = 201) and the other comprising elementary education teachers (n = 158). The nonparametric results indicated that the content of the PROPSIT is sufficiently multidimensional to be able to describe a variety of psychosocial factors, while the parametric results require modification of the measurement model to obtain greater factorial congruence. In general, the analyses show a similar structure to those discussed by previous preliminary studies that have reported similar item-level performances. Some findings and considerations for future research are discussed.

RESUMEN

The structural attributes and correlates of items have an effect on their composite scores and exploring them strengthens the content validity of a measure adapted to another context. The objective of this study was to evaluate the item properties of a measure of psychosocial work factors (PWFs). Data were collected through a web platform from 188 Peruvian working adults (men = 101, 50.5%) holding various professions and jobs. The instrument was the Psychosocial Processes at Work Scale (PROPSIT), adapted for the Peruvian context. The distributional characteristics, the efficiency of its response options and its correlates with engagement, occupational self-efficacy, general stress and psychological distress (explored with a coefficient of maximum information and another of monotonic association) were analyzed. It was found that the items were asymmetrically distributed, without statistical normality and with a response tendency at low (for psychosocial risk factors (PSRFs)) and medium (favorable psychosocial resources) levels. The number of efficient response options was lower (approximately five options) than the original structure (seven options). The monotonic associations with gender and age were essentially zero and theoretically converged with the external constructs, except for some items related to job demands. The contributions of the results to the content validity of the PROPSIT and the orientation of working hypotheses about PROPSIT item constructs and measures of work effects are discussed.

RESUMEN

Sensation seeking is a construct associated with risky behaviors over a wide age range, but validation studies in Mexico are lacking. The aim of this study was to investigate the validity of two versions of the Brief Sensation Seeking Scale (the BSSS-8 and BSSS-4) in young Mexican individuals. The sample consisted of 2884 students (age: M = 16.6, SD = 1.5) from five preparatory schools in Morelos, Mexico. The internal structure of the BSSS was evaluated according to the structural equation modeling (SEM) parameterization, including measurement invariance (compared to the factor loadings obtained in the meta-analysis); conditional reliability; and equivalence between versions. The unidimensionality and measurement invariance (configurational, factor loadings, thresholds, intercepts, and residuals) across sex and age groups were satisfactory, and the factor loadings were highly congruent with those obtained in the meta-analysis. Reliability was suitably high (greater than 0.80), especially near the mean scores, but was lower for extreme scores. Thus, the instrument was concluded to be optimal for defining the construct of sensation seeking, consistent with the findings of previous studies.

RESUMEN

Resumen El Utrecht Work Engagement Scale (UWES), medida de engagement laboral, ha tenido controversias respecto a la interpretación de su dimensionalidad, es decir, si sus puntajes pueden ser unidimensionales, multidimensionales o de dos niveles (unidimensional y multidimensional). El presente estudio tuvo por objetivo examinar la estructura interna (dimensionalidad, invarianza de medición y confiabilidad) del UWES (dos versiones: larga y breve) en una muestra de 636 trabajadores peruanos. Se aplicó el modelamiento de ecuaciones estructurales para la evaluación de tres modelos de dimensionalidad: un solo factor (unidimensionalidad), tres factores relacionados (multidimensionalidad) y bifactor (dos niveles de interpretación: factor general y factores específicos). Los resultados indican que, luego de aplicar el modelamiento bifactor, la varianza común obtenida de un factor general es más fuerte que la interpretación de tres dimensiones. Este resultado se repitió en ambas versiones del UWES (larga y breve). La invarianza de medición fue satisfactoria en el nivel configuracional, métrica y escalar (en ambas versiones). Con respecto a la consistencia interna, se obtuvieron coeficientes satisfactorios (mayores a .70). Se concluye que el modelo de tres dimensiones del UWES para obtener los puntajes debe ser reemplazado por un modelo unidimensional, representado con un puntaje total. Se discuten las implicaciones teóricas y prácticas.

Abstract The Utrecht Work Engagement Scale (UWES), a measure of work engagement, has had controversies regarding the interpretation of its dimensionality, that is, whether its scores can be one-dimensional, multidimensional or two-level (one-dimensional and multidimensional). The dimensionality of the UWES has been questioned mainly due to the high covariation between its components, an aspect consistently verified in the observed scores and latent variables (De Bruin y Henn 2013), even by the same authors (Schaufeli et al., 2006). This has two implications, one operational and one conceptual. In the operational context, the calculation of scores is also influenced by the statistical differentiation of the factors found in the factor analyzes. This means that if one or more factors are retained and justified, this also determines the same number of observed scores that can be calculated and interpreted. On the other hand, the conceptual implication is that the comprehensive framework of a three-dimensional psychological phenomenon differs from the one-dimensional. For example, the differentiation between dimensions generates the possibility of different trends between dimensions (e. g., one of three is high and the other low) and in this case, the concept of engagement becomes very generic and ambiguous to name and understand the different possibilities. Specific combination of its dimensions or jeopardizes its content validity, implying the need for other more specific concepts, which although related to engagement, can be independent. The objective of the present study was to examine the internal structure (dimensionality, measurement invariance and reliability) of the UWES (two versions: long and short) in a sample of 636 Peruvian workers. Structural equation modeling was applied to evaluate three dimensionality models: a single factor (one-dimensionality), three related factors (multidimensionality) and bifactor (two levels of interpretation: general factor and specific factors). The results indicate that, after applying bifactor modeling, the common variance obtained from a general factor is stronger than the three-dimensional interpretation. This result was repeated in both versions of the UWES (long and short). The measurement invariance was satisfactory at the configurational, metric and scalar levels (in both versions). Regarding internal consistency, satisfactory coefficients (greater than .70) were obtained. Three issues emerge from this study that modify the original theoretical interpretation of the UWES (which consists of using three related factors). The first is the existence of a general factor underlying the items, and which is statistically substantial as a source of variance of the items, independent of specific factors. In this general factor, the items generally contribute to their variance, except for two items whose discriminative capacity is moderately low (11 and 13, both of the specific factor Absorption). The main element of this general factor is the Dedication factor, whose items completely represented this general factor. Second, the differentiation of two specific factors corresponding to Vigor and Absorption does not appear to be psychometrically sufficient to describe nested constructs within the engagement construct, and therefore its independent interpretation of the general factor could be questioned. However, a contrary argument is that both factors show different amount of specific variance, although low compared to the general factor; for example, Absorption shows more divergent validity compared to Vigor, while the latter contains more common variance (general factor). Third, Dedication was completely absorbed by the general factor, and is only relevant insofar as its items are completely related to the general factor. Therefore, this component lost statistical autonomy and, consequently, very poor conceptual differentiation. It is concluded that the UWES - three-dimensional model to obtain the scores must be replaced by a one-dimensional model, represented with a total score. Implications are future research are discussed.

RESUMEN

Resumen El propósito del presente estudio es examinar la validez de constructo y consistencia interna del Inventario Peruano de Mindfulness y Ecuanimidad. Basado en el análisis factorial y la Teoria de Respuesta al Item (Modelo de Crédito Parcial y el Método de Escalabilidad de Mokken), se examinó la magnitud de los parâmetros y se estimò la varianza de cada uno de los items para contribuir en el constructo general de mindfulness. La muestra del estudio está compuesta por 602 adultos, estudiantes de tres instituciones acadêmicas de educación superior de Lima, Chiclayo y Chimbote en el Perú. Los resultados de estos análisis indican una estructura unidimensional del instrumento, en función a ocho items representados por los atributos de atención, consciencia, aceptación, juicio de valor, y ecuanimidad. Los indicadores de ajuste del modelo de factores oblicuos para los items seleccionados fueron satisfactorios: CEI = .982, RMSEA = .043 (IC90% = .029, .056), SRMR = .048, SB--2 (gl: 35) = 73.415 (p > 0.05).

Abstract 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: CEI = .982, RMSEA = .043 (lC90% = .029, .056), SRMR = .048, SB- -2 (gl: 35) = 73.415 (p > 0.05).

RESUMEN

OBJECTIVE: The objective was to provide psychometric evidence of the 14-item and 10-item version of the Perceived Stress Scale in nursing professionals from Peru. METHOD: Data on 2848 professionals (92.275% women) between 23 and 69 years old (M = 21.876; SD = 10.763) was extracted from ENSUSALUD 2015. An exploratory structural equation modelling (ESEM) was applied with Mplus 7.0 software to analyse several measurement models in the PSS: unidimensional, bidimensional, models with method factor, and bifactor. Finally, the reliability was analysed. RESULTS: The two-factor structure obtained adequate fit indices, and acceptable factorial loadings (>.50), while the unidimensional model has poor statistical support. The construct and score reliability was also adequate. CONCLUSION: The two-factor model of the PSS-10 and PSS-14 presents adequate psychometric properties to expand its use to empirical research.

RESUMEN

The objective was to determine the validity of the UWES-3, an ultrashort measure of work engagement lacking evidence in Hispanic populations. In total, 200 workers with heterogeneous positions and careers from Metropolitan Lima were enrolled via nonprobabilistic sampling. The UWES-3 and measures of external variables (work accidents, stress overload, and others) were used. Data were collected through a web platform. Items were analysed, nonparametric response theory methods (Mokken scale analysis and Ramsay curves) were applied to the items, and ordinal and linear regression were used to determine the relationships with external variables. The items had statistically similar distributional properties and monotonic associations with external variables but with fewer functional response options. The UWES-3 complied with the monotonic homogeneity model and invariant ordering of items; the scaling of the items, score (greater than 0.80), and reliability (0.94) were high. With the effects of age and sex controlled, the UWES-3 significantly predicted minor accidents at work and job satisfaction and revealed effects of stress overload and perceived efficacy. The theoretical implications of the UWES-3 as a brief unidimensional measure integrating the three original dimensions of the instrument and the practical implications of its use for research and professional practice are discussed.

RESUMEN

The internal structure of the Multidimensional Scale of Perceived Social Support (MSPSS) in adolescents has been evaluated with some factorial analysis methodologies but not with bifactor exploratory structural equation modeling (ESEM), and possibly the inconsistency in the internal structure was dependent on these approaches. The objective of the study was to update evidence regarding its internal structure of MSPSS, by means of a detailed examination of its multidimensionality The participants were 460 adolescents from an educational institution in the Callao region, Lima, Peru. The structure was modeled using unidimensional, three-factor and bifactor models with confirmatory factor analysis (CFA) and ESEM approaches. The models showed good levels of fit, with the exception of the unidimensional model; however, the multidimensionality indicators supported the superiority of the bifactor ESEM. In contrast, the general factor was not strong enough, and the interfactorial correlations were substantially lower. It is concluded that the MSPSS can be interpreted by independent but moderately correlated factors, and there is possible systematic variance that potentially prevented the identification of a general factor.
