Factor structure of BDI in general population: the simplified Beck Depression Inventory and the theory of homeostatically protected mood

Languages of publication



Objective. This study aimed to analyze the factor structure of the simplified Beck Depression Inventory BDI-S translated from German and attempted for a theoretical justification of its items based on the theory of homeostatically protected mood. BDI-S uses a frequency scale instead of the original rating of the degree of the measured behavior by separate descriptions (21x4 descriptions); thus creating a tool with a four times lower number of items. Method. The questions were answered by N = 1108 people aged from 18 to 70. As in the case of BDI-II, the PAF (principal axis factoring) method and oblique rotation (Promax) were used on half of the participants to analyze the structure of BDI-S; and CFA was used on the other half of the participants. Gender invariance was verified and factor reliability was determined. Results. Using EFA the two-factor structure found by the authors of the original BDI-II questionnaire in students (cognitive-affective dimension, factor 1; and somatic dimension, factor 2) was not supported, but the somatic-affective and cognitive dimensions, which were found by the authors of the original BDI-II in patients (Beck et al., 1996) were supported. CFA confirmed the identified two-factor structure, which was invariant in terms of gender. Conclusions. The two identified dimensions of BDI-S in the general population represent the contents identified by BDI-II in patients. An attempt to apply the theory of homeostatically protected mood seems to be unsuccessful for two reasons: a) In the questionnaire, depressed mood and loss of pleasure and interest are not sufficiently represented, namely, they were not represented by the separate factor in the results; b) In the general population, it can be expected that there will be no longer-lasting negative change in the homeostatically protected mood. Study limitation. The results may have been affected by online data collection at the time of the pandemic.
