Datset for Construct Validity of Beck's Hopelessness Scale (BHS): Analysis trough S-1 Bifactor Model in a Large Argentine Sample.
Description
Despite the fact that The Beck Hopelessness Scale (BHS) has been widely used and considerate an instrument recognized for its predictive capabilities of suicidal ideation and attempt; its factor structure is still a topic of debate. It becomes necessary to propose models for resolving these disputes. One of such approach is the bifactor S-1 model. This is a power modeling approach that gives a G an unambiguous meaning and avoids anomalous results associated to fully symmetrical modeling. The main objective of this work is to verify the fit of a bifactor S-1 model for BHS, contrasted with other models that contemplate methods effects too. We take a sample of 2,164 Argentines through an open mode on-line sample method. The results indicate that the S-1 bifactor model with positive word as referenced items achieves the best and optimal fit indices. The complementary receiver operating characteristic curve shows that the area under the curve obtained gives an optimal precision for discriminating between people with high and no suicidal ideations. These results allow to give clarity on the factorial structure of the BHS, showing evidence in favor of the construct validity of a computerized version of the BHS.
