ABUIN, Manuel R.  e  RIVERA, Luis de. Measuring psychological and psychosomatic symptoms: the Brief Symptom Check List (BSL-50). Clínica y Salud [online]. 2014, vol.25, n.2, pp.131-141. ISSN 2174-0550.  https://dx.doi.org/10.1016/j.clysa.2014.06.001.

The Brief Symptom Check List (LSB-50) is an instrument for psychopathological assessment used for the screening of both psychological and psychosomatic symptoms. The LSB-50 defines nine clinical scales and subscales, as well as an index of psychopathological risk, three global indexes and two validity scales. The purpose of this study was to evaluate the reliability and validity of the LSB-50 for psychopathological assessment. The material consisted of data from 1,242 subjects, who filled out the LSB-50; 790 subjects belonged to non-clinical samples, and the rest of them, 452, belonged to clinical samples. Reliability analysis obtained alpha coefficients of the nine scales and subscales in a range from .79 to .90. Analyses of both factorial validity and criterion validity (correlation of LSB-50 dimensions with both interpersonal dependency and bonding variables and discriminant analyses), supported significant validity for the instrument. Possible implications on the conceptualization of both psychoreactivity and psychopathological syndromes are discussed.
