Suicide Prevention and Intervention in Spain: the SURVIVE Study

The BSI is a 53-item self-report scale designed to evaluate psychopathological and psychological symptoms, measuring nine dimensions (i.e.,somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism) that can be summed up to reflect three global indices. These synthetic indices are the General Severity Index (GSI), the Positive Symptom Distress Index, and the Positive Symptom Total. In more detail, the BSI uses a 5-point Likert scale, ranging from 0 ("not at all") to 4 ("extremely"). Scores range from 0 to 212, higher scores mean a worse outcome.

The PHQ-9 measures depressive symptoms in a scale from 0 (not at all) to 3 (nearly every day). Scores range from 0 to 27 and higher scores mean a worse outcome. The PHQ-9 A will be used for participants aged 12-17.

GAD-7 consists of seven items measuring worry and anxiety symptoms. Each item is scored on a four-point Likert scale (0-3) with total scores ranging from 0 to 21 with higher scores reflecting greater anxiety severity.

Part one provides a self-reported description of health problems into five dimensions. Patients have to rate the severity of each dimension in a 5-point scale. For part one, higher scores represent a worse outcome (less quality of life).Part two consist of a Visual Analogue Scale corresponding to the current state of the subject's health. The lowest extreme (0) corresponds to the worst imaginable state, and the highest extreme (100) represents the best imaginable health state.

The BIS is a 30-item widely used questionnaire that measures three aspects of impulsivity: 1) motor impulsiveness (acting without forethought), 2) attentional impulsiveness (tendency to make quick, non-reflexive decisions), and 3) non-planned impulsiveness (failure to prepare for future events). Each item is rated in a 4 point scale (0-4). Total scores range from 0 to 44, higher scores represent higher impulsivity.

Acquired Capability for Suicide Scale-Fearlessness about Death (ACSS-FAD) is a seven-item self-report measure which uses a 5-point Likert scale ranging from 0 (not at all like me) to 4 (very much like me). Scores range from 0 to 32, and higher scores represent a worse outcome (higher levels of the acquired capability for suicide).

The 8-item version of the Reflective Functioning Questionnaire is a self-reported instrument that measures reflective functioning, an expression of mentalizing processes. The instrument separately addresses the levels of both certainty and uncertainty about one's own mental processes. Items are scored in a 7 point-scale (1 to 7), meaning that the total score ranges from 8 to 56, higher scores represent a higher capacity of mentalizing, and therefore a better outcome.

The Columbia Suicide Rating Scale is a suicidal ideation and behavior rating scale that evaluates suicide risk.It rates an individual's degree of suicidal ideation on a scale, ranging from "wish to be dead" to "active suicidal ideation with specific plan and intent and behaviors. It contains 6 "yes" or "no" questions in which respondents are asked to indicate whether they have experienced several thoughts or feelings relating to suicide over the past month and behaviors over their lifetime and past 3 months. An answer of "yes" to any of the six questions may indicate a need for referral and an answer of "yes" to questions 4, 5 or 6 indicate high-risk.
