SCL‐90‐R profiles in a sample of severely violent psychiatric inpatients

Abstract

A sample of 39 patients who had committed serious violent acts toward others were assessed with the revised Symptom Checklist (SCL-90-R). The SCL-90-R is a self-report symptom inventory for the measurement of psychopathology in psychiatric and medical patients. In addition to the patients' selfreport, an observer-rated SCL-90-R was obtained. This was accomplished by letting one pair of nurses complete SCL-90-R ratings for each patient. The first aim of the study was to compare the SCL-90-R self-report scores of the patient sample with the psychiatric inpatient norms [Derogatis LR (1992): Clinical Psychometric Research Inc]. Another purpose of this study was to explore possible trends of discordance between the observer ratings and the self-reports of the study group. Always considering the limitations of the small sample, it was nevertheless also of interest to look for possible sex differences and differences between violent subgroups and between diagnostic groups in the selfreported scores as well as in the observer ratings. The most striking findings of the present study were that the self-reported scores were lower than the inpatient norms for SCL-90-R and that the patients' self-reported levels of distress were significantly lower than those found in the observer ratings. Underreporting of psychopathology as a marker of violence risk is discussed in light of these findings. In this study, women reported higher distress levels than men in the Interpersonal Sensitivity symptom dimension. There were no significant differences concerning SCL-90-R ratings between patients who had committed homicide, attempted homicide, or physically assaulted another person in a serious but not life-threatening way.

The antecedents of aggressive behavior among men with schizophrenia: a prospective investigation of patients in community treatment

“…This association was explained by scores on the Novaco Anger Scale and the Barrat Impulsiveness Scale . Thus, the way in which participants with psychosis are questioned influences the number and type of symptoms that are elicited as does the source of information, patient or staff, who report the symptom (Bjørkly, 2002c).…”

Psychometric properties of the Symptom Checklist-90 in adolescent psychiatric inpatients and age- and gender-matched community youth

“…The SCL-90 has been tested in different settings, including community [ 6 , 9 – 13 ] and psychiatric outpatient [ 14 , 15 ] and inpatient samples [ 16 – 18 ]. It is commonly used as an indicator of change in symptoms [ 19 , 20 ] and as a treatment outcome measure [ 21 , 22 ].…”

Violence and phases of illness: Differential risk and predictors

“…primary disorders, differences in the ways symptoms are assessed [1,7], collecting data on symptoms retrospectively, and failing to control for factors known to be associated with physical aggression such as prior aggressive behavior and substance misuse. We reasoned that the inconsistency may also be due to measuring the association in patients with varying levels of positive symptoms, from florid psychosis to few active symptoms.…”
