The Subjective Vitality Scale (SVS) assess the subjective experience of being full of energy and alive, a clinically relevant outcome measure of positive psychological well-being. The purpose of this paper was to translate the 7-item SVS into Spanish and examine its psychometric properties. In Study 1 (n = 790 adolescents) and Study 2 (n = 130 athletes) reliability and exploratory factor analysis (EFA) were carried out. In Study 1 and Study 3 (n = 197 dancers) evidence of validity of inferences based on SVS scores estimating relationships with other variables (life satisfaction, global self-esteem and emotional and physical exhaustion) was obtained. In Study 2 invariance across time was tested. Finally in Study 3, the factorial structure was cross-validated using confirmatory factor analysis (CFA). Results of EFA showed a one-factor solution. CFA also supported a unidimensional factor structure for the Spanish 6-item SVS (RMSEA = .050 (90% CI = .00, .080); NNFI = .993; CFI = .996). Reliability analysis indicated a strong internal consistency in all study samples (α ranged from .82 to .89). Further, results from multi-sample analysis supported the replicability of SVS factor structure across time. Finally, the SVS scores showed the expected correlations patterns (all them significant, p < .01) with the measured outcomes. In conclusion, the Spanish version of the SVS demonstrated adequate psychometric properties, indicating that the scale can be confidently used to measure the experience of possessing energy and aliveness; furthermore, differences across time can be meaningfully carried out.

After the Multidimensional Inventory for Religious/Spiritual Well-Being (MI-RSWB) was validated as a reliable instrument for the Western European context it is primarily intended in this study to translate the measure into Spanish and adapt it for the Mexican culture. Furthermore we investigate whether spirituality/religiosity has a similar impact on indicators of personality and subjective well-being in Mexico as it does in samples drawn from Western European cultures. 190 students (99 females) from public and private universities in Guadalajara, all Mexican citizens, were involved in this study. We found strong evidential support for the six factor solution of the Original MI-RSWB in this Mexican population. By mirroring previous research the measure showed a highly satisfying internal consistency (α = .91 for the total score and .75 or higher for all six sub dimensions). Furthermore the total RSWB score was observed to be related with Eysenck’s personality dimensions Extraversion (r = .24, p < .01), and Psychoticism (r = –.28, p < .001), although not with Neuroticism. There was also a positive correlation with Sense of Coherence (r = .31, p < .001). In conclusion, the dimensionality of RSWB and its associations with personality and subjective well-being was well supported in this first application within a Mexican cultural context.

Three studies aimed at developing the Spanish version of the Inventory of Parent and Peer Attachment (IPPA; Armsden & Greenberg, 1987) and at analyzing its factor structure are reported. In Study 1, the Spanish translation of items and their content analysis was carried out via cognitive interviews. In Study 2, the three-factor structure proposed by authors was tested in a sample of 417 adolescents (270 girls and 147 boys) using confirmatory analysis, and indexes showed a suboptimal fit. A principal component analysis yielded one-dimensional structures in father, mother and peer versions, explaining 54.3%, 50.8%, and 50.8% of the variance respectively. On the basis of the factor loadings and of the item-total correlations, a shortened version of the inventory was created. Convergent validity was tested with measures of family climate, parenting socialization and self-esteem. In Study 3, the one-dimension structure was confirmed in a new sample of 604 adolescents (335 girls and 269 boys). Based on all factor analyses and convergent validity indices obtained, we conclude that the Spanish IPPA questionnaire reliably and validly assesses adolescent attachment using only a dimension of attachment security.

The aim of this study was to validate the Basque version of the CDS (Children's Depression Scale, Lang & Tisher, 1978), one of the most widely used questionnaires for the assessment of childhood depression, which has already been proved to be a valid and reliable tool in different cultures. The questionnaire was administered to a community sample of 886 participants (432 males and 454 females) aged between 8 and 16. A two-factor solution was obtained (Depressive dimension and Positive Dimension), which accounted for 29.86 % of the variance. Reliability with regard to internal consistency level and long-term stability was good (α = .95 and .79; and R = .73 and .59 for Depressive and Positive dimensions, respectively). Analysis of Differential Item Functioning with respect to age and gender showed that 91% and 88% of the items, respectively, did not present DIF. External validity evidence for the questionnaire was also obtained. We consider that the present work offers researchers and professionals interested in this area of study a valid and reliable tool for assessing depressive symptoms in Basque-speaking children and adolescents.

The purpose of this study was to examine the extent to which the Spanish POMS assesses the same factors as the original form of the questionnaire. We started from a version with 63 items, representing seven conceptual dimensions. This version was administered to a sample of 364 adult athletes. In the whole sample, exploratory factor analytic findings suggested a more parsimonious measurement model, with 44 items and 6 first-order factors. Then the data from said sample were randomly divided into two sets, each containing about 50% of the subjects. The fit of the first sample set (n = 166) to the proposed model was adequate. Four of the main goodness-of-fit indices exhibited the following values: CFI = .95, NNFI = .95, SRMR = .083, and RMSEA = .064. We tested the same model in the second data set (n = 198), in which the fit was also acceptable, with values of .95, .94, .088, and .066 for CFI, NNFI, SRMR, and RMSEA, respectively. In addition, we used multi-group confirmatory factor analysis to provide evidence on the invariance of the model.

The aim of this study is to adapt the ESPA29 scale of parental socialization styles in adolescence to the Basque language. The study of its psychometric properties is based on the search for evidence of internal and external validity. The first focuses on the assessment of the dimensionality of the scale by means of exploratory factor analysis. The relationship between the dimensions of parental socialization styles and gender and age guarantee the external validity of the scale. The study of the equivalence of the adapted and original versions is based on the comparisons of the reliability coefficients and on factor congruence. The results allow us to conclude the equivalence of the two scales.
