| | 335 adolescents between 14 and 19 years old, from Chile | Ryff’s PWBS, reduced version (van Dierendonck adapted to Spanish by | Internal consistency (Cronbach’s alpha). Construct validity using structural equation models. Comparison of the theoretical model with two proposed alternatives. | Three scales have a good internal reliability (positive relationships with others .75; purpose in life .78, and self-acceptance .78). The remaining three scales have from acceptable to bad values (autonomy .67; personal growth .63, and environmental mastery .59). The tested models were: Five factors where self-acceptance and environmental mastery are in one factor, six factors, five factors with self-acceptance and environmental mastery in a factor with a second order factor, six factors with a second order factor, six factors with a second order factor which includes self-acceptance, environmental mastery, personal growth and purpose in life. The model with the best fits is the six-dimensional model with a second-order factor, called personal well-being. Cronbach’s alpha reliabilities was between .57 and .78. | The six-dimensional model had the best fit, although the reliabilities were not quite good. The five-dimensional model had a good fit, similar to the six-dimensional model, but with better reliabilities. It is evident that the high correlation among the scales may be part of the problem. |
| | 691 university students between 17 and 30 years, from Chile. | Ryff’s PWBS, reduced version (van Dierendonck adapted to Spanish by | Exploratory and confirmatory factor analyses. Descriptive analyses for each item. Internal reliability (Cronbach’s alpha). Correlations among the scales. Structural equation modeling. | The internal consistency of the six-dimensional model is similar to the original, with the following values in the scales: self-acceptance .79; positive relations with others .75; autonomy .67; environmental mastery .62; purpose in life .54, and personal growth .78. To verify the dimensionality, two successive analyzes were performed, one of exploratory type that yielded six dimensions and another model of six factors was generated, keeping only the items with factor loadings equal or greater than .30. The factors were reconfigured, although several items were explained by the same factor. The hexadimensional model had a reasonable model fit with factor loadings between .26 and .72. The correlations among the factors were in the range between .97 and .55. | The hexadimensional model has a reasonable model fit to be used in this sample. High correlations among some dimensions indicate that they might be redundant and collinear. |
| | 250 people between 60 and 87 years, from Chile | Ryff’s PWBS, reduced version (van Dierendonck adapted to Spanish by | Internal Consistency (Cronbach’s alpha). | Problems with the internal reliability were detected on two scales, which led to the elimination of three of the seven items from the personal growth scale and to completely eliminate the environmental mastery scale. The final scale was composed of the scales of self-acceptance, positive relations with others, autonomy, personal growth, and purpose in life, with a total of 30 items. | There is no conclusion regarding the scale since the study had a different objective that was not specific to the PWBS. |
