RESUMO

BACKGROUND: Balanced scales control for acquiescence (ACQ) because the tendency of the respondent to agree with the positive items is cancelled out by the tendency to agree with opposite-pole items. When full balance is achieved, ACQ is not expected to affect external validity. Otherwise, attenuated estimates are expected to appear if no control methods such as Lorenzo-Seva & Ferrando’s (2009) are used.  Method: Expected results were derived analytically. Subsequently, a simulation was carried out to assess (a) how ACQ impacted external validity and (b) how validity estimates behaved when ACQ was corrected. Two illustrative examples are provided. RESULTS: A sizable number of items and/or high content loadings tended to decrease ACQ’s impact on validity estimates, making the empirical coefficient closer to its structural value. Furthermore, when scales were well balanced, the controlled and uncorrected scores were close to each other, and led to unbiased validity estimates. When the scales were unbalanced and no corrections were used, attenuated empirical validity coefficients inevitably appeared. CONCLUSIONS: Designing a well-balanced test or correcting for ACQ are the best ways to minimize attenuation in external validity estimation.

RESUMO

El objetivo del presente estudio es analizar si la curiosidad es una variable moderadora entre la Impulsividad y la Orientación Emprendedora. Se utiliza una muestra multiocupacional de 883 empleados españoles (49 % hombres, 51 % mujeres), obtenidos mediante un muestreo no probabilístico. Se ha utilizado el programa SPSS 23.0. Se encontraron correlaciones estadísticamente significativas entre todas las variables de la investigación a excepcion de la impulsividad Funcional. Finalmente, la evidencia empírica indica que la Curiosidad-D tiene un papel moderador entre la impulsividad Disfuncional y la Orientación Emprendedora mostrada, en el sentido de que la Curiosidad-D (entendida como una variable cuantitativa) afecta la intensidad de la relación entre la Impulsividad Disfuncional (variable predictora) y la Orientación Emprendedora (variable de criterio)


The objective of the present study is to analyze whether the variable Curiosity is a moderating variable between Impulsivity and Entrepreneurial Orientation. The multi-occupational sample of 883 Spanish and Colombian employees (49% men, 51% women) was obtained through non-probabilistic sampling. The data collected were processed with the SPSS 23.0 program. Statistically significant correlations were found among all the research variables except for Functional Impulsivity. Finally, empirical evidence indicates that Curiosity-D plays a moderating role between Dysfunctional Impulsivity and Entrepreneurial Orientation in the sense that Curiosity-D (understood as a quantitative variable) affects the intensity of the relationship between Dysfunctional Impulsivity (predictor variable) and Entrepreneurial Orientation (criterion variable)

RESUMO

Professional drivers often have problems sleeping or resting properly. This may be due to various factors, both personal and specific to their working conditions. In this study, we set out to develop a predictive model for the quality of sleep in professional drivers using the following indicators: Age, Gender, Seat Comfort, Seat Suspension, Adjustable Lum-bar Support of the Driver's Seat, Driving Hours, Musculoskeletal Problems, Driver Stress, Irritation, Resistant Personality, Burnout, Safety Behaviors and Impulsivity. METHOD: The participants were 369 professional drivers from different transport sectors, obtained through non-probabilistic sampling. The SPSS 25.0 program was used for statistical analysis. RESULTS: The predictive capacity of certain variables that affect drivers' sleep quality is determined. CONCLUSIONS: Sleep quality can be predicted by means of certain variables, the best predictor of which is Exhaustion (Burnout). This research contributes to the body of knowledge on sleep quality and on improving the health of professional drivers

RESUMO

The study objective is to create a scale specifically for measuring driver fatigue and to analyze the scale's psychometric properties. The participants were 518 Spanish drivers. We carried out an exploratory factor analysis (EFA) and the first subsample obtained a single-item solution (eight items). We then performed a confirmatory factor analysis (CFA) with a second subsample. The results were root mean square error of approximation (rmsea) = 0.05, comparative fit index (CFI) = 0.94 and Tucker-Lewis index (TLI) = 0.92, which corroborates the previous results and maintains the same number of elements. The resulting dimension shows good reliability. The scale scores were then related to several external correlates and other scales, and showed good convergence and criteria validity. The results indicate that the scale for assessing work fatigue specifically in professional drivers - driver fatigue (DF-8) - is a reliable and valid instrument.

RESUMO

BACKGROUND: A worker's work habits can affect their health, both physically and psychologically. Negative results have been associated with work demands (stress, anxiety and depression). OBJECTIVE: In the present research we carried out a predictive study of work addiction by applying three questionnaires on depression and anxiety. METHODS: In this study, the participants were 332 workers, obtained through non-probabilistic sampling. The FACTOR (version 7.2) and SPSS 23.0 programs were used. RESULTS: The results of the correlation analysis show both positive and negative associations with the variables studied. We conclude that work addiction variables can predict anxiety and depression because we found that two variables predict 18.3% of depression and 20.3% of anxiety, which are feelings generated by work and excessive work. CONCLUSION: It can be concluded that feelings generated by work and excessive work predict anxiety and depression, thus the present research helps to broaden knowledge on work addiction, promoting a healthy lifestyle and prevent absenteeism.

RESUMO

Professional drivers are considered prone to health risks. For this reason we have conducted a predictive study to analyze variables that may be predictors of stress in driving. Participating in this study were 372 drivers (93.4% men, 6.6% women) recruited through non-probabilistic sampling. The aim of the study is to develop a prediction model for job stress in professional drivers using the following indicators: personality, impulsiveness, hardy personality, job, age, seat comfort, seat suspension, lumbar support and driving hours. We found that the variables with predictive power over driving stress were: commitment over relaxed driving (ΔR2 = 0.101; ß = 0.135), danger prevention (ΔR2 = 0.139; ß = 0.342) and fatigue and anxiety (ΔR2 = 0.063; ß = -0.227); control over alertness and vigilance (ΔR2 = 0.069; ß = 0.278); agreeableness over sensation-seeking (ΔR2 = 0.047; ß = -0.268). In conclusion, driver stress can be predicted by certain variables. This study contributes to better understanding of driver stress and promotes safety at the wheel, thus helping to prevent traffic accidents.

RESUMO

Recent studies show that quarantine and lockdown are effective measures for controlling COVID-19 outbreaks, but may be an unpleasant experience with psychological consequences. For this reason, the main aim of this study was to determine which personal sociodemographic and psychological variables are related to adapting to lockdown in a Spanish population. Questionnaires were administered to 2,055 individuals (60.7% women) who were resident in Spain and aged between 18 and 80 years old. We also administered some items related to feelings and behaviors during lockdown. The results showed that sex and age are variables to be taken into account. In fact, women tended to show greater stress, a more pessimistic attitude, and lower self-esteem. However, older people adapted better to lockdown although they were also more worried. Married people also adapted better although they too were more worried. The results also showed that more resilient people, with higher subjective happiness and life satisfaction, develop strategies for adapting positively to adversity, and tend to adapt better to lockdown, with more positive attitudes and behaviors. In terms of personality traits, higher neuroticism and lower extraversion were related to worse adaptation to lockdown. This study also showed that lockdown has had a negative psychological impact on those people who did not adapt well to the situation and the changes during the first 4 weeks of lockdown.

RESUMO

Callous-unemotional traits are considered to be precursors of psychopathy, and are related to behaviors such as aggression, delinquency, antisocial behavior, and bullying in adolescents. For this reason, it is important to study these traits in childhood and adolescence with appropriate and reliable instruments. The aim of the current study is to develop a Mexican adaptation of the Inventory of Callous-Unemotional Traits and Antisocial Behavior (INCA) because few questionnaires in Spanish assess these traits, and even fewer have been validated for the Mexican population. The INCA questionnaire, developed in Spain, assesses the same three factors as the ICU questionnaire (unemotional, callousness, and uncaring), and it includes an additional factor of antisocial behavior with items on challenging authority and breaking social rules. It controls two response biases: social desirability and acquiescence. We administered the Mexican adaptation, named INCA-M, to 699 adolescents aged between 12 and 18 years old. Factor analysis yielded three dimensions, because most of the items referring to uncaring and antisocial behavior loaded on a common factor, which can be explained by cultural differences. We decided to remove these items of antisocial behavior so as to maintain the same three factors assessed by the ICU questionnaire. The results suggest that the INCA-M has good psychometric properties, with high factor simplicity and good reliability. Moreover, we found the expected correlations with impulsivity and the Big Five subscales, and also with the equivalent subscales assessed by the ICU questionnaire.

RESUMO

BACKGROUND: The suitability of using reversed items in typical response measures has been a matter of controversy for many years. While some authors recommend their use, others reject them due to their undesirable effects on tests' psychometric properties. The present research intends to analyse a third alternative based on the use of reversed items plus a procedure to control response bias effects. METHOD: We analysed two forms of the same test, one with direct and reversed items and another composed only of direct items, and compared them both before and after applying a procedure to control response biases. RESULTS: The factorial structure and factorial reliability of both versions was almost equivalent after controlling response biases. When no effect biases were controlled, the version with both types of items exhibited less acceptable psychometric properties. CONCLUSIONS: The use of reversed items is not advisable without the application of a procedure to control response bias effects. When such effects are mitigated, the results are equivalent to those obtained with only direct items, but with the added value of controlling for acquiescence effects


ANTECEDENTES: la utilización de ítems invertidos en medidas de respuesta típica ha sido durante mucho tiempo una cuestión controvertida. Mientras algunos autores aconsejan su utilización, otros la rechazan debido a sus efectos indeseables en las propiedades psicométricas de las medidas. El presente estudio pretende analizar una tercera vía, basada en el uso de ítems invertidos juntamente con un método para eliminar los efectos de los sesgos de respuesta. MÉTODO: se analizaron dos versiones de una misma prueba, una incorporando ítems directos e invertidos y otra compuesta únicamente de ítems directos. Posteriormente se compararon ambas versiones antes y después de controlar los efectos de los sesgos de respuesta. RESULTADOS: la estructura factorial y la fiabilidad de las puntuaciones factoriales de ambas versiones tras eliminar los efectos de los sesgos de respuesta fue equivalente, mientras que la versión con ambos tipos de ítems sin control de sesgos mostró peores propiedades psicométricas. CONCLUSIONES: la utilización de ítems revertidos sin la aplicación de un método de control de sesgos está claramente desaconsejada. Cuando dichos métodos se utilizan los resultados de ambas versiones son equivalentes con el añadido que en la versión con ítems revertidos se controlan los efectos de aquiescencia

RESUMO

The best predictors of attention deficit hyperactivity disorder (ADHD) were examined using Conners 3 ADHD Index (Conners 3 AI) (teacher and parent reports), Child Behaviour Checklist for ages 6-18 (CBCL/6-18) and Youth Self Report for ages 11-18 (YSR/11-18) in a sample of 350 schoolchildren from the Epidemiological Project on Neurodevelopmental Disorders (EPINED) (n = 2,818). The diagnosis was made on the basis of the DSM-5 criteria and the three presentations of ADHD were categorised as non-diagnosis (n = 175), subclinical (n = 56) or clinical (n = 118). Discriminant analyses showed that the CBCL attention problems scale was the best predictor, correctly classifying almost 80% of cases (78.4% unadjusted model; 79.2% model adjusted for IQ and socioeconomic level). The slow cognitive time scale was the best predictor of inattention presentation (68.7% unadjusted; 71.0% adjusted) and the DSM scale of attention problems was the best predictor of hyperactive-impulsive (71.1% unadjusted; 78.0% adjusted) and the combined (68% unadjusted; 71.0% adjusted) presentation. Predictors did not differ between models for two (nondiagnostic and clinical) or three diagnostic categories (non-diagnostic, subclinical and clinical)


Se examinaron los mejores predictores del trastorno de deficit de atencion e hiperactividad (TDAH) considerando el Indice de TDAH de Conners 3 (Conners 3 AI), el Listado de comportamientos infantiles/6-18 (CBCL/6-18) y el Autoinforme juvenil/11-18 (YSR/11-18) en 350 escolares. El diagnostico se realizó con base en los criterios DSM-5 y se consideraron las categorías de no-diagnostico (n = 175), subclinico (n = 56) y clínico (n = 118) con las tres presentaciones de TDAH. Los análisis discriminantes mostraron que la escala de problemas de atención del CBCL fue el mejor predictor, clasificando correctamente casi el 80% de los casos (78,4% modelo no ajustado; 79,2% modelo ajustado por el cociente intelectual y nivel socioeconomico). Para la presentación de inatención el mejor predictor fue la escala de tiempo cognitivo lento (68,7% no ajustado; 71,0% ajustado) y para las presentaciones hiperactivo-impulsivo (71,1% no ajustado; 78,0% ajustado) y combinada (68% no ajustado; 71,0% ajustado) la escala DSM de problemas de atención. Los predictores no difirieron entre los modelos para dos (no-diagnostico y clínico) o tres categorias diagnosticas (no-diagnostico, subclinico y clinico)

RESUMO

The aim of this study was to conduct a correlational-predictive study of the antecedent variables of Passion towards Work. The participants were 513 workers (48.1% male, 51.9% female), obtained through non-probability sampling. We used the FACTOR 7.2 and SPSS 22.0. In the results we find that variables such as Personality, Engagement, Self-efficacy, obsessive-compulsive component, Life satisfaction and Lifestyle were predictive of Passion towards Work. In conclusion Passion towards Work can be predicted as follows: The variables Dedication, Growth, Physical activity, Satisfaction with life and Excessive responsibility were direct predictors of Harmonious Passion whereas Vigor was an inverse predictor. Similarly, the variables Absorption and Excessive responsibility were predictors of Obsessive Passion, whereas Satisfaction with life, Openness to experience and Kindness were negative predictors

RESUMO

BACKGROUND: Recent studies have suggested a relationship between certain personality variables and work addiction. In the present work we conduct a predictive study of the background variables of work craving through the variables Impulsivity, Personality, Perfectionism, Self-esteem and Self-efficacy. METHOD: The participants were 332 workers obtained by non-probability sampling. We used the FACTOR programs (version 7.2) and SPSS 23.0. RESULTS: The predictive capacity of personality variables and self-esteem is determined on the work craving. CONCLUSIONS: Work craving can be predicted through certain variables (Emotional Stability, Perfectionism and Self-esteem). This research contributes to greater knowledge of work addiction and to the empowerment of a healthy lifestyle that can be affected by addiction to work. No funding has been received to make this article


Estudios recientes has sugerido que hay relación entre algunas variables de personalidad y la adicción al trabajo. En el presente trabajo nos hemos planteado el objetivo de realizar un estudio Predictivo de las variables antecedentes del Work Craving a través de las variables Impulsividad, Personalidad, Perfeccionismo, Autoestima y Autoeficacia.: Los participantes han sido 332 trabajadores, obtenidos mediante un muestreo no probabilístico. Para analizar los datos se ha utilizado el programa SPSS 23.0. Los resultados del análisis de correlación nos muestran asociaciones tanto positivas como negativas con las variables estudiadas. El análisis de regresión determina la capacidad predictiva de las variables Estabilidad emocional, Perfeccionismo y Autoestima que explican el 24.40 % de la varianza de los Sentimientos Generados por el Trabajo (WCS.FW). Y las variables Estabilidad emocional y Autoestima explican el 14.0 % de la Necesidad de trabajar (WCS.NW). Se puede concluir que el Work Craving puede predecirse a través de determinadas variables (Estabilidad emocional, Perfeccionismo y Autoestima), contribuyendo la presente investigación a un mayor conocimiento de la Adicción al Trabajo. Los resultados poseen implicaciones prácticas importantes que debe considerarse para la gestión estratégica adecuada de los recursos humanos dentro de las organizaciones.

RESUMO

Callous-unemotional traits are defined as potential markers of psychopathy in children and adolescents. Previous studies with the most widely used instrument designed specifically to assess these traits, the Inventory of Callous-Unemotional Traits (ICU), have shown major methodological problems. For this reason, the purpose of the present study was to develop a valid and reliable test to assess callous-unemotional traits for the adolescent population free of the response biases social desirability (SD) and acquiescence (AC). In order to obtain responses free of these biases, we used SD item markers as well as content balanced items to identify a factor related to SD and AC, so that SD and AC effects can be removed from the individual scores on content factors. As well as the CU traits (unemotional, callousness, and uncaring scales), this new questionnaire also contains an additional scale for assessing antisocial behaviors. The test was administered to 719 adolescents between 13 and 19 years old. Exploratory and confirmatory factor analysis yielded the following expected four dimensions with a good fit: Unemotional, Callousness, Uncaring, and Antisocial Behavior. These scales also showed good psychometric properties with good reliability, and convergent, discriminant and criterion validity.

RESUMO

Background: This study sets out the psychometric properties of the TRANS-18 scale and of a shorter version, the TRANS-12, both designed to detect safe behaviors (personal and vehicle-related) and psychophysiological disorders among professional drivers. Method: The investigation was divided into Study 1, into the factorial structure, reliability and validity of the TRANS-18, and Study 2, looking into the same aspects of the TRANS-12. The participants in both studies were resident in Spain. 272 professional drivers took part in Study 1, while Study 2 had 326 participants. Results: A confirmatory factor analysis was carried out for both studies. The results for Study 1 confirm an internal structure of three factors related to psychophysiological disorders and personal and vehicle-related safety behaviors, but the original TRANS-18 is discarded because it does not fit the model. With regard to Study 2, the results show a good fit of the three-factor model, appropriate reliability and evidence of validity. Conclusions: We conclude by considering the suitability of the psychometric properties of the TRANS-12 and its utility for identifying safe behaviors in work in the transport industry


Antecedentes: Este estudio expone las propiedades psicométricas de la escala TRANS-18 y de una versión más corta, el TRANS-12, ambos diseñados para detectar conductas seguras (personales y relacionadas con el vehículo) y trastornos psicofisiológicos entre conductores profesionales. Método: La investigación se divide en dos. Estudio 1, estructura factorial, fiabilidad y validez del TRANS-18, y Estudio 2, se estudian los mismos aspectos en el TRANS-12. Los participantes en ambos estudios fueron residentes en España. 272 conductores profesionales participaron en el Estudio 1, mientras que el Estudio 2 participaron 326 conductores. Resultados: Se realizó un análisis factorial confirmatorio para ambos estudios. Los resultados del Estudio 1 confirman una estructura interna de tres factores relacionados con los trastornos psicofisiológicos y las conductas de seguridad personales y con el vehículo, pero el TRANS-18 original se descarta por no ajustarse al modelo. Con respecto al Estudio 2, los resultados muestran un buen ajuste del modelo de tres factores, la fiabilidad apropiada y la evidencia de validez. Conclusiones: Concluimos considerando la idoneidad de las propiedades psicométricas del TRANS-12 y su utilidad para identificar comportamientos seguros en el trabajo en la industria del transporte

RESUMO

Background: Resistance to change is the tendency to resist or avoid making changes; in addition, change is perceived as aversive. Resistance to change is a professional competence that can be evaluated. Objective: To adapt from the original English into Spanish the Resistance to Change Scale (RTC) by Oreg (2003) in two countries, Spain and Argentina. Method: The participants were 482 employed workers from Spain (Study 1) and 171 managers from Argentina (Study 2). Results: The results are presented in two studies and an unifactorial structure is demonstrated after exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) are performed. The factor obtained has adequate reliability and evidence of validity is also confirmed if some external correlates and certain scales dealing with pro/anti-change behaviors, self-efficacy, the hardy personality and impulsivity are taken as references. Conclusions: This scale could be an ideal instrument for correctly identifying RTC and it can be used as a screening tool in combination with other instruments


Antecedentes: La resistencia al cambio es la tendencia a resistir o evitar hacer cambios; además, el cambio se percibe como aversivo. La resistencia al cambio es una competencia profesional que puede ser evaluada. Objetivo: Ha sido realizar una adaptación al español de la Resistance to Change Scale (RTC) de Oreg (2003) del original inglés en dos países, España y Argentina. Método: Los participantes son 482 empleados de España (Estudio 1) y 171 directivos de Argentina (Estudio 2). Resultados: Se presentan los resultados en dos estudios y se demuestra una estructura unifactorial, después de realizar el análisis factorial exploratorio (EFA) y el análisis factorial confirmatorio (CFA). Además, el factor obtenido tiene una fiabilidad adecuada e igualmente se constatan evidencias de validez si se toman como referencia algunos correlatos externos y algunas escalas que hacen referencia a conductas pro/anti-cambio (pro/anti-change behaviors), la autoeficacia (self-efficacy), la personalidad resistente (hardy personality) y la impulsividad (impulsivity). Conclusiones: la presente escala puede resultar idónea para identificar de manera apropiada la RTC y puede ser utilizada como una herramienta de screening en combinación con otros instrumentos

RESUMO

BACKGROUND: Nomophobia, which is a neologism derived from the combination of "no mobile," "phone," and "phobia" is considered to be a modern situational phobia and indicates a fear of feeling disconnected. OBJECTIVE: No psychometric scales are available in Italian for investigating such a construct. We therefore planned a translation and validation study of the Nomophobia Questionnaire (NMP-Q), which is an instrument developed by Yildirim and Correia. Subjects were recruited via an online survey using a snowball approach. METHODS: The NMP-Q was translated from English into Italian using a classical "backwards and forwards" procedure. In order to explore the underlying factor structure of the translated questionnaire, an exploratory factor analysis was carried out. A principal component analysis approach with varimax rotation was performed. Multivariate regression analyses were computed to shed light on the psychological predictors of nomophobia. RESULTS: A sample of 403 subjects volunteered to take part in the study. The average age of participants was 27.91 years (standard deviation 8.63) and the sample was comprised of 160 males (160/403, 39.7%) and 243 females (243/403, 60.3%). Forty-five subjects spent less than 1 hour on their mobile phone per day (45/403, 11.2%), 94 spent between 1 and 2 hours (94/403, 23.3%), 69 spent between 2 and 3 hours (69/403, 17.1%), 58 spent between 3 and 4 hours (58/403, 14.4%), 48 spent between 4 and 5 hours (48/403, 11.9%), 29 spent between 5 and 7 hours (29/403, 7.2%), 36 spent between 7 and 9 hours (36/403, 8.9%), and 24 spent more than 10 hours (24/403, 6.0%). The eigenvalues and scree plot supported a 3-factorial nature of the translated questionnaire. The NMP-Q showed an overall Cronbach alpha coefficient of 0.95 (0.94, 0.89, and 0.88 for the three factors). The first factor explained up to 23.32% of the total variance, while the second and third factors explained up to 23.91% and 18.67% of the variance, respectively. The total NMP-Q score correlated with the number of hours spent on a mobile phone. CONCLUSIONS: The Italian version of the NMP-Q proved to be reliable.

RESUMO

The problems associated with violence during adolescence have been on the rise in recent decades. Many studies have focused only on environmental causes or individual causes of violence, although a combination of both variables would seem to be the best option for prediction. The current study aims to assess the relevance of individual characteristics (personality traits, intelligence, and historical and clinical factors linked to the risk of violence), contextual risk factors and protective factors in explaining antisocial and delinquent behaviors in adolescence by comparing three different samples: a community sample, a sample at risk of social exclusion, and a sample of juvenile offenders. The results show that the samples at risk of social exclusion and the sample of juvenile offenders have a very similar profile in terms of personality traits and intelligence, although they differ from the community sample. However, these two samples do differ in such contextual variables as peer delinquency, poor parental management, community disorganization, or early caregiver disruption.

RESUMO

Several studies have shown that personality self-reports may be affected by response biases, and that this may have consequences on their factor structure, especially in samples with little education or in adolescents. The current study aims to understand the effect of social desirability and acquiescence on the factor structure of three questionnaires based on the Five Factor Model of personality: the Big Five Inventory, the Five Factor Personality Inventory and the Overall Personality Assessment Scale. The data was analysed using a new method that removes the effects of both social desirability and acquiescence from the inter-item correlation matrix used for factor analysis. These effects were assessed in a sample of 392 university students, which contained no individuals with low educational levels, children or adolescents. The results showed that, even in samples with no individuals with low educational levels, controlling for social desirability and acquiescence led to a simpler factor structure that is more congruent with the theoretical solution expected from the five factor model. It also seems that in the domain of inventories based upon the five factor model, this effect may be specially due to acquiescence (AU)


Diversos estudios muestran que los tests de personalidad pueden verse afectados por los sesgos de respuesta, lo que puede tener consecuencias en su estructura factorial, especialmente en muestras con bajo nivel educativo o adolescentes. El objetivo del presente estudio consiste en determinar cuál es el efecto de la deseabilidad social y la aquiescencia en la estructura factorial de tres cuestionarios basados en el modelo de los Cinco Grandes factores de personalidad: Big Five Inventory, Five Factor Personality Inventory y Overall Personality Assessment Scale. Los datos se analizaron a partir de un nuevo método que elimina los efectos de la deseabilidad social y la aquiescencia de la matriz de correlaciones inter-item utilizada en el análisis factorial. La muestra está compuesta por 392 estudiantes universitarios, por lo que no incluye individuos con bajo nivel educativo, niños o adolescentes. Los resultados indican que, incluso en muestras sin individuos con bajo nivel educativo, controlar la deseabilidad social y la aquiescencia da lugar a una estructura factorial más simple y congruente con la solución teórica esperada a partir del modelo de los Cinco Grandes. Además, los resultados sugieren que en los tests basados en este modelo, este efecto puede ser debido especialmente a la aquiescencia (AU)

RESUMO

Passion for work has a great influence on workers'; occupational health. Vallerand and his collaborators define two types of passion: harmonious and obsessive. With the first, people feel obliged to carry out an activity but freely decide to do it and do so in harmony with other aspects of their lives. With the second, although the person likes the activity, they feel obliged to take part in it because of internal circumstances that exercise control over them. In this context, our objective was to adapt Vallerand and Houlfort's Passion Toward Work Scale (PTWS) into Spanish. The participants were 513 workers selected through non-probability sampling. We used the FACTOR (version 7.2), SPSS 20.0 and Mplus 6.12 programs. The results of the confirmatory factor analysis (exploratory structural equation modelling) of the PTWS support the two-factor model (harmonious passion and obsessive passion), presenting appropriate reliability and evidence of validity with burnout, irritation, engagement and self-efficacy. The PTW scale and questionnaire are therefore reliable and valid instruments that are suitable for use in Spanish


La Pasión por el trabajo tiene una gran influencia en la salud laboral de los trabajadores. Vallerand y sus colaboradores proponen dos tipos de pasión, la armoniosa y la obsesiva. En la primera las personas se sienten obligadas a realizar una actividad, pero libremente deciden hacerla y además se encuentra en armonía con otros aspectos de la vida de la persona. Y en la segunda, aunque a las personas les guste una actividad, se sienten obligados a participar en ella a causa de contingencias internas que los controlan. En este contexto, el objetivo planteado fue la adaptación al castellano de la Escala de Pasión por el Trabajo (PTW) de Vallerand y Houlfort. Los participantes han sido 513 trabajadores, obtenidos mediante un muestreo no probabilístico. Se han utilizado los programas FACTOR (versión 7.2), SPSS 20.0 y Mplus 6.12 En la escala PTW, los resultados del AFC (ESEM) apoyan el modelo de dos factores (Pasión Armoniosa y Pasión Obsesiva), presentando una fiabilidad adecuada e indicios de validez con: Burnout, Irritación, Engagement y Autoeficacia. Las Escala PTW es un instrumento fiable y válido, adecuado para ser usado en castellano
