“…As previously reported ( 47 ), we used a deductive method of item generation ( 48 ) where we combined two pre-existing scales that were used in prior studies with adolescents: the Community Assessment of Psychic Experiences—Positive scale [CAPE-P15 ( 49 )], and the Brief Self-report Questionnaire for Screening Putative Pre-psychotic States [BQSPS ( 50 )]. We assessed the following domains: bizarre experiences (BE, 6 items), perceptual anomalies (PA, 3 items), social anxiety (SA, 3 items), and negative symptoms (NS, 3 items).…”

Evidence for Specific Associations Between Depressive Symptoms, Psychotic Experiences, and Suicidal Ideation in Chilean Adolescents From the General Population

Associations between psychotic experiences and suicidal ideation are not yet fully understood, and the potential role of depressive symptoms in this relationship remains unclear. The current study examined relationships between depressive symptoms (DS), psychotic experiences (PE) and suicidal ideation (SI) using two complementary approaches on cross-sectional data from a community sample of adolescents aged 13–19 years (N = 1,591). First, we investigated the association between the three domains using mediation analysis, showing that depressive symptoms partly mediate the relationship between psychotic experiences and suicidal ideation. Second, we looked at associations between the three domains at item level using network analysis. Specific associations between symptoms of the three domains were found, indicating depressive symptoms of sadness, avolition, pessimism, and self-criticalness/worthlessness as the most central symptoms in the network. Suicidal ideation was associated with the depressive symptoms pessimism and worthlessness, to social anxiety, and to perceptual anomalies. Our results show that the mediating effect of depressive symptoms between psychotic experiences and suicidal ideation may be due to associations between specific aspects of SI, depressive symptoms and psychotic experiences. These findings can contribute to the planning of health services and programs aimed at the timely detection of psychopathology and suicidal risk in young people.

Early detection of trauma-related psychopathology is fundamental for preventing symptom escalation in adolescents, and this strategy can be carried out by developing accurate measures. The aim of this study is to provide preliminary evidence for the internal structure, construct validity, reliability, sensitivity, and specificity of a brief screening instrument for posttraumatic stress disorder (PTSD) and complex PTSD (C-PTSD) in general population adolescents. 1,501 Chilean adolescents participated by responding to the Brief PTSD scale (BPTSD) along with a battery of additional questionnaires. The internal structure of the eight-item BPTSD was assessed through exploratory and confirmatory factor analyses, while criterion validity was assessed through receiver-operating characteristic (ROC) curves. Confirmatory factor analysis (CFA) demonstrated a two-dimensional internal structure that is in accordance with literature regarding C-PTSD. Our results suggest that BPTSD may measure PTSD with complex features rather than C-PTSD. The scale showed adequate reliability, and criterion validity. The BPTSD is a brief, reliable, and simplyworded measure for PTSD symptoms and C-PTSD features in adolescents. Public Significance StatementPTSD and complex PTSD can be severe in adolescents. Detection of PTSD symptoms is fundamental for early intervention in trauma, but it requires simple yet effective measures. The adjusted BPTSD is a short and reliable measure that assesses PTSD symptoms and complex PTSD features in the general population, adolescents, and young people.

Coexisting service-related factors preceding suicide: a network analysis

ObjectivesThe overall objective was to analyse service-related factors involved in the complex processes that precede suicide in order to identify potential targets for intervention.Design and settingExplorative network analysis study of post-suicide root cause analysis data from Swedish primary and secondary healthcare.Participants217 suicide cases reported to the Swedish national root cause analysis database between 2012 and 2017.Primary and secondary outcome measuresA total of 961 reported incidents were included. Demographic data and frequencies of reported deficiencies were registered. Topology, centrality indices and communities were explored for three networks. All networks have been tested for robustness and accuracy.ResultsLack of follow-up, evaluations and insufficient documentation issues emerged as central in the network of major themes, as did the contributing factors representing organisational problems, failing procedures and miscommunication. When analysing the subthemes of deficiencies more closely, disrupted treatments and staffing issues emerged as prominent features. The network covering the subthemes of contributing factors also highlighted discontinuity, fragile work structures, inadequate routines, and lack of resources and relevant competence as potential triggers. However, as the correlation stability coefficients for this network were low, the results need further investigation. Four communities were detected covering nodes for follow-up, evaluation, cooperation, and procedures; communication, documentation and organisation; assessments of suicide risk and psychiatric status; and staffing, missed appointments and declined treatment.ConclusionThe results of this study suggest that healthcare providers may improve patient safety in suicide preventive pathways by taking active measures to provide regular follow-ups to patients with elevated suicide risk. In some cases, declined or cancelled appointments could be a warning sign. Tentative results show organisational instability, in terms of work structure, resources and staffing, as a potential target for intervention, although this must be more extensively explored in the future.

Examining relationships between psychotic experiences and suicidal ideation in adolescents using a network approach

Abstract: Suicidal ideation is differentially connected to specific psychotic experiences. Auditory PE, persecutory ideation, and social anxiety symptoms could play a central role in the interconnectedness of the two constructs.
