The Beck Depression Inventory: testing and cross-validating a second-order factorial structure for Swedish...

The intent of the present study was to test for the validity and equivalency of a second-order factorial structure of the Beck Depression Inventory for and across three independent samples (n1 = 661; n2 = 239; n3 = 196) of nonclinical Swedish adolescents. The model under study derived from a cross-validated study of Canadian high school adolescents. Model fitting, testing and equating were based on the analysis of covariance structures within the framework of a confirmatory factor analytic model. Of major importance was the tenability of the hypothesized model for Swedish adolescents. Only minor differences where found among samples, which involved correlated errors and one cross-loading (Sample 2). Results are expected to be of substantial interest to both researchers and clinicians whose concerns focus on depression as it bears on this population.
