This study evaluated the psychometric properties of the German version of the 21-item Exercise Dependence Scale (EDS-G), which was administered in a large representative German sample (N = 1,611). In order to examine convergent validity, we also asked participants to answer the Eating Disorder Examination-Questionnaire (EDE-Q). To investigate the discriminant validity, clients of fitness centers (N = 129), sport students (N = 85), and medical students (N = 129) filled out the EDS-G. In this German population-based sample, the seven-factor structure suggested by the original authors as well as a higher-order model (7 + 1 factor model) were supported. The total EDS-G scale showed an excellent internal reliability and was positively related to the EDE-Q total and subscale scores. The EDS-G scores differentiated between samples with varying degrees of exercise. In summary, the results indicate that the EDS-G is a psychometrically sound and potentially valid brief measure for the assessment of exercise dependence symptoms.

  El artículo presenta un estudio psicométrico de la Escala de Dependencia al Ejercicio Físico –Revisada (EDS-R) en usuarios de gimnasios colombianos con el objetivo de analizar su estructura factorial, consistencia interna, confiabilidad de constructo y su validez convergente, discriminante y de criterio. Se realizó una investigación instrumental en la que participaron 515 usuarios de gimnasios (44.3 % hombres y 55.7 % mujeres) con edades entre los 18 y los 58 años (Md = 25; RIQ = 21-30) de la ciudad de Medellín. Se analizó la versión en español (Sicilia & González-Cutre, 2011) de la Escala de Dependencia al Ejercicio Físico –Revisada (EDS-R) (Downs, Hausenblas & Nigg, 2004). Se ejecutaron análisis factoriales confirmatorios y exploratorios. Resultados: la estructura original de la EDS-R mostró una adecuada consistencia interna y validez factorial, confirmada a través de los índices de bondad de ajuste para el modelo de siete dimensiones. El alfa de Cronbach fue de .917 y el coeficiente de dos mitades de Guttman fue de .924. Los índices de bondad de ajuste para la versión original fueron: PCMIN/DF = 2.291; RMR = .091; GFI = .917; AGFI = .886; CFI = .951; RMSEA = .056 (90% CI = .049 - .063); PCLOSE = .093. Sin embargo, los valores de la varianza media extraída, la máxima varianza compartida y la fiabilidad máxima pusieron en evidencia dificultades con la confiabilidad de constructo, la validez convergente y validez discriminante. Tampoco hubo buenos resultados al analizar la validez de criterio. Para analizar si los datos en la muestra se ajustaban mejor a una estructura factorial diferente, se realizó un análisis factorial exploratorio complementario que llegó a un modelo de cinco factores, con los mismos 21 ítems. Sin embargo, la evaluación de la fiabilidad compuesta, validez convergente y validez discriminante arrojó mejores resultados que el modelo de siete factores. Abstract: The article presents a psychometric study of the Physical Exercise Dependence Scale-Revised (EDS-R) in Colombian gym users with the aim of analyzing its factorial structure, internal consistency, construct reliability and its convergent, discriminant and criterion validity. An instrumental research was carried out with the participation of 515 gym users (44.3 % men and 55.7 % women) aged between 18 and 58 years (Md = 25; RIQ = 21-30) from the city of Medellín. The Spanish version (Sicilia & González-Cutre, 2011) of the Physical Exercise Dependence Scale-Revised (EDS-R) (Downs, Hausenblas & Nigg, 2004) was analyzed. Confirmatory and exploratory factor analyses were performed. Results: The original structure of the EDS-R showed adequate internal consistency and factorial validity, confirmed through the goodness-of-fit indices for the seven-dimensional model. Cronbach's alpha was .917 and the Guttman two-half coefficient was .924. The goodness-of-fit indices for the original version were: PCMIN/DF = 2.291; RMR = .091; GFI = .917; AGFI = .886; CFI = .951; RMSEA = .056 (90% CI = .049 - .063); PCLOSE = .093. However, the values for mean variance extracted, maximum shared variance and maximum reliability revealed difficulties with construct reliability, convergent validity and discriminant validity. There were also no-good results when analyzing criterion validity. To analyze whether the data in the sample fit better to a different factor structure, a complementary exploratory factor analysis was performed that arrived at a five-factor model, with the same 21 items. However, the assessment of composite reliability, convergent validity and discriminant validity yielded better results than the seven-factor model.

Introduction: There are several instruments to evaluate behavioural addictions. Furthermore, several specific scales have been developed to assess various aspects of exercise dependence. Nevertheless, in Spain there is a lack of specific instruments designed to assess exercise dependence.Objective: This study aims to examine the psychometric properties of a Spanish version of the Exercise Dependence Scale-Revised.Method: 175 university students who were regular exercisers (M=59.11, SD=15.89) took part in the study. They were requested to complete the EDS-R, as well as the General Addiction Scale. The requirement to take part in the study was to exercise a minimum of four times per week.Results: Findings provide initial support for the psychometric properties of the scale as its internal consistency (Cronbach’s alpha: 0.907), and construct and convergent validity with the EAG-RC (r=.559; p<.001) are adequate. In addition, its structure did not need to be modified, as it kept the 21 original items from the American version. Factor analysis yielded a five-factor structure (tolerance, loss of control, continuity, intensity, and withdrawal symptoms) which differ from the ones obtained in the original (American) and French versions where seven factors were obtained. This correlated five-factor model explains 50% of the variance.Conclusion: This Spanish EDS-R, which presents adequate psychometric properties, will provide researchers and clinicians with specific data on this screening tool for assessing exercise dependence. Further research is needed to confirm the current results and check its validity both in research and clinical practice.

Objective In recent years, resilience has become a focus of research in the medical and behavioral sciences. The Brief Resilience Scale (BRS) was developed to assess the individual ability to recover from stress (“to bounce back”) after experiencing adversities. The aim of the study was to validate the Czech and Slovak versions of the BRS. Methods A representative sample of the Czech and Slovak populations (NCZ = 1800, mean age MCZ = 46.6, SDCZ = 17.4, 48.7% of men; NSK = 1018, mean age MSK = 46.2, SDSK = 16.6, 48.7% men) completed a survey assessing their health and well-being. Several confirmatory factor analysis (CFA) models of the BRS were compared to find the best fit. Cronbach’s alpha and McDonald’s omega coefficients of reliability were evaluated. Convergent validity was assessed by correlating resilience (BRS), physical and mental well-being (SF-8) and psychopathology symptoms (BSI-53). Differences in gender and age groups were appraised. Results A single-factor model with method effects on the reverse items was evaluated to best fit the data in both the Czech and Slovak samples (χ2CZ(6) = 39.0, p < 0.001, CFICZ = 0.998, TLICZ = 0.995, RMSEACZ = 0.055, SRMRCZ = 0.024; χ2SK(6) = 23.9, p < 0.001, CFISK = 0.998, TLISK = 0.995, RMSEASK = 0.054, SRMRSK = 0.009). The reliability was high in both samples (αCZ = 0.80, ωCZ = 0.85; αSK = 0.86, ωSK = 0.91). The BRS was positively associated with physical and mental well-being and negatively associated with somatization, depression and anxiety. In both countries, a lower BRS score was associated with higher age. Czech men reported significantly higher BRS scores than women. No significant difference was found in the mean BRS scores between the two countries. Conclusion This study provides evidence of good psychometric properties, reliability and validity of the Czech and Slovak adaptations of the BRS.

It has been researched for several decades using various scales depending on the definition of psychological empowerment chosen by a reasercher. However, there is a lack of widely applicable, compact instruments for a reliable and valid assessment of psychological empowerment. Furthermore, there has been a lack of empowerment research in Lithuania. Therefore, the purpose of this study is to construct a Lithuanian psychological empowerment questionnaire and to evaluate its psychometric properties (reliability and validity).The strategy of the empirical construction of a questionnaire was used. At first, statements to describe the concept of psychological empowerment were generated, using group interviews and expert evaluation. Fifteen final items were included into the Lithuanian Psychological Empowerment Questionnaire (LPEQ). Then, an empirical research was performed: 189 respondents from 8 organizations filled up the LPEQ, G.M. Spreizer (1995) Psychological Empowerment Questionnaire (PEQ), B. E. Ashforth (1990) Helplessness Scale, Intrinsic Motivation Scale (Warr et al., 1979), and socio-demografic questions.The results of the study have revealed that the LPEQ has a high internal reliability (Cronbach α = 0.909). Five factors were extracted using the exploratoryfactor analysis, three items each. Psychological empowerment was defined based on five dimensions: meaning, enthusiasm, decision making, authonomy, and trust in competence. The Cronbach α was between 0.755 and 0.880 for the dimension level. These five dimensions show support for the existing models of psychological empowerment (Spreitzer, 1995; Menon, 2001), but also they supplement these models with for instance, the dimension of enthusiasm.The convergent validity of the LPEQ was confirmed by strong correlations (p < 0.01) between the LPEQ and the PEQ subscales, and the Intrinsic Motivation Scale. It was supported by a negative correlation between the LPEQ subscales and the Helplessness Scale. Based on the analysis of correlations, the discriminant validity of the LPEQ dimensions’ levels was confirmed.In conclusion, the Lithuanian Psychological Empowerment Questionnaire (LPEQ) can be characterized as an instrument with appropriate psychometricproperties for the use in research and practice. Directions for the future research in the field have been offered.Key words: psychological empowerment, psychological empowerment questionnaire, reliability, validity.

Abstract Background Mindfulness-based meditation practice (MBP) can be assessed in terms of time spent (quantity) or skill acquisition (quality), but these components have rarely been delineated in adherence measures. Individuals may also engage in MBP through everyday life (informal practice) and dedicate specific time for MBP (formal practice). Method The Mindfulness Adherence Questionnaire, a scale designed to assess quantity and quality of formal and informal MBP was evaluated. Study 1 used a cross-sectional design to examine internal reliability and construct validity (N = 282). Study 2 examined test–retest reliability and sensitivity (N = 55) during a 4-week mindfulness intervention. Results A nested-factor model showed adequate fit: MAQ items loaded on both the general factor (Practice) and specific factors (Formal and Informal). Discriminant validity analyses revealed the MAQ captured MBP adherence distinct from trait mindfulness. Quality of both formal and informal mindfulness practice was more strongly associated with higher levels of trait mindfulness than quantity. Changes in MAQ Quantity scores were observed over time. Conclusions The MAQ is reliable and has a meaningful scale structure, may usefully distinguish both quality versus quantity and formal versus informal MBP, and is sensitive to variations in MBP and does not solely measure trait mindfulness.

Decision Making Factors

Past research on career decision-making has focused on two distinct modes of decision-making: logic and intuition. In this study, we extend that two-system model of career decision-making and examine the role of two additional decision-making modalities: advice seeking and spiritual discernment. We conducted two independent studies through which we develop and validate a Career Discernment Scale by examining its dimensions and internal reliability (Study 1), followed by research to establish discriminant and convergent validity (Study 2). Results provide initial support for the dimensionality and reliability of four distinct career decision-making factors, demonstrated by a clear factor structure and internal consistency. In addition, our results show evidence of convergent and discriminant validity through expected correlations across a nomological network of individual differences. Overall, this article highlights the unique role of spirituality and advice seeking in career decision-making with implications for career development and practice.

Core Self

In this study the validation of a German-language Core Self-Evaluations Scale (CSES; Judge, Erez, Bono, & Thoresen, 2003) is presented. Core self-evaluations are fundamental appraisals that individuals hold about their own capability, effectiveness, and worthiness as a person (Judge et al., 2003). Data were collected from 2 samples, 200 from the workforce and 134 students. The data supported the underlying single-factor solution. The German-language CSES (G-CSES) was found to be reliable and shows convergent validity with regard to internality (Krampen, 1981) and International Personality Item Pool (IPIP40) neuroticism, extraversion, and conscientiousness scales (Hartig, Jude, & Rauch, 2003) and discriminant validity with regard to the IPIP40 openness scale. The scale correlates significantly with job satisfaction and life satisfaction. Additionally, the G-CSES is incrementally valid over and above traits of the 5-factor model of personality.

Purpose Although Colquitt’s Organizational Justice Scale (COJS) is one of the most widely used organizational justice scales (OJS) worldwide, a rigorous adaptation and validation in Italy is still missing. Accordingly, the purpose of this paper is to examine the construct validity and reliability of the Italian translation of the scale. Design/methodology/approach Factorial and concurrent validity were examined to assess construct validity. A confirmatory factorial analysis through structural equation modelling was conducted on five factorial models: one-factor, two-factor, three-factor, four-factor and second-order factor model. Concurrent validity implied the examination of the relationships between organizational justice and job satisfaction (convergent validity) and between organizational justice and workplace bullying (discriminant validity). Findings Evidence of the prevalence of the original Colquitt (2001) four-factor model was found, though also the second-order model obtained adequate goodness of fit. Findings supported both convergent and discriminant validity. Reliability analysis reported evidence of excellent internal consistency. Thus, the Italian version of the OJS can be used in Italy for research and practical purposes. Originality/value This is the first study properly addressing the factorial and concurrent validity of the OJS in Italy.

Commitment Level

Commitment has often been used to examine why individuals unjustifiably persist in relationships that are lacking in or devoid of satisfaction. However, the practicality of using commitment to examine these situations has been questioned because of its substantial association with satisfaction. Across three studies, we created a measure of nonvoluntary dependence and investigated the validity and reliability of the Nonvoluntary Dependence Scale from an investment model perspective. Exploratory and confirmatory factor analyses revealed evidence of a single factor and reliability analyses revealed good internal reliability for the measure. The new measure also evidenced desirable convergent and discriminant validity with respect to a number of existing individual- and relationship-level constructs. Consistent with hypotheses, nonvoluntary dependence was significantly associated with commitment level, investments, and alternatives but not with relationship satisfaction. Differences in nonvoluntary dependence were also found between individuals in aggressive versus nonaggressive relationships, with no differences found in commitment level. Implications regarding this new measure, as well as directions for future research, are discussed.
