标题:“Test Your Spirituality in One Minute or Less” Structural Validity of the Multidimensional Inventory for Religious/Spiritual Well-Being Short Version (MI-RSWB 12)
摘要:Background: The Multidimensional Inventory for Religious/Spiritual Well-Being (MI-RSWB 48) was developed in order to address a religious/spiritual dimension as being an important part of psychological well-being. In the meantime, the instrument has been successfully applied in numerous studies. Subsequently, a short version, the MI-RSWB 12 was constructed, especially for the use in clinical surroundings. Here it is intended to contribute to the further development of the MI-RSWB 12 by investigating its structural validity through structural equation modeling. Materials and Methods: A total sample of 1097 German-speaking adults (744 females; 67.8%; Age range: 18 – 69 years) from the normal population filled in the MI-RSWB 12 via an online-survey. In line with theoretical assumptions 5 different factor structure models for the MI-RSWB 12 were tested: 1) a single-factor model, 2) a model with four correlated RSWB dimensions, 3) a single higher-order model with four lower order factors, 4) a two higher-order model with four lower order factors, 5) a bifactor model, which includes four specific RSWB dimensions. Results: The single-factor model provided the poorest model fit, with no indices falling within the acceptable range as outlined by Kline (2015). The higher-order model showed an acceptable model fit, however exceeded the acceptable χ² to df ratio with χ²/df > 3. In contrast, the four-factor, two higher-order factors and the bifactor models showed overall good fit indices. With regard to the Akaike information criterion (AIC), the four-factor model demonstrated superiority compared to both the two higher-order factor model and the bifactor model, which in turn showed did not differ from each other. Conclusion: Four different MI-RSWB 12 sub-scales should be calculated in future studies, while a general factor and two higher order factors are statistically valid as well. Further applications of the MI-RSWB 12, especially in the clinical patient groups, are encouraged.
