[Behavior dyscontrol scale: validation and initial results]

The numerous recent trials devoted to disruptive behavior disorders indicate the renewed interest of clinicians for these so-called dimensions and call for revision of the instruments with which they are evaluated. The present paper provides a brief review of the currently used scales for rating impulsivity. A new scale for evaluating the behavioural dyscontrol is proposed. The items of this scale are selected a priori according to clinical experience with patients suffering from lack of behavioural control. The Behaviour Dyscontrol Scale (BDS) includes, in the initial version, 4 parts. The first part concerns the generalized lack of control (G-BDS). This is a questionnaire of 24 items. The second part is constituted by a questionnaire which lists a number of specific behaviours where impulsivity has a central role (S-BDS). Part III is constituted with 4 Visual Analogue Scales for evaluating handicap linked to dyscontrol. Part IV is constituted by 3 Visual Analogue Scales concerning the physician global impression about the lack of general control in cognitions, emotions and behaviours. For validation, 166 patients (111 females and 55 males), either hospitalized or ambulatory, and 35 controls (16 females and 19 males) were included in this study. Mean age of patients was 38.5 (SD = 10.5) years. The patients population is subdivided in 4 subgroups, anxious, depressed, abusers and bulimics according to DSM III-R criteria. Patients and controls global scores were significantly different at the G-BDS (p less than 10(-4)) and not at S-BDS.(ABSTRACT TRUNCATED AT 250 WORDS)
