SummaryBackgroundMedically serious suicide attempts have been recognized as the most important predictor of suicide. The Computerized Suicide Risk Scale based on backpropagation neural networks (CSRS-BP) has been recently found efficient in the detection of records of patients who performed medically serious suicide attempts (MSSA).ObjectivesTo validate the CSRS-BP by: 1) using the CSRS-BP with patients instead of records; 2) comparing the ability of expert psychiatrists to detect MSSA, using the CSRS checklist; and 3) comparing the results of the Risk Estimator for Suicide (RES) and the self-rating Suicide Risk Scale (SRS) with the CSRS-BP.MethodsTwo hundred fifty psychiatric inpatients (35 MSSA and 215 non-MSSA) were diagnosed by clinicians using the SCID DSM-IV. Three expert psychiatrists completed the CSRS checklist, and the RES for each patient, and the patients completed the self-report SRS assessment scale. The CSRS-BP was run for each patient. Five other expert psychiatrists assessed the CSRS checklists and estimated the probability of MSSA for each patient. Comparisons of sensitivity and specificity rates between CSRS-BP, assessment scales and experts were done.ResultsInitially, the CSRS-BP, RES, SRS, and experts performed poorly. Although sensitivity and specificity rates significantly improved (two to four times) after the inclusion of information regarding the number of previous suicide attempts in the input data set, results still remained insignificant.ConclusionsThe CSRS-BP, which was very successful in the detection of MSSA patient records, failed to detect MSSA patients in face-to-face interviews. Information regarding previous suicide attempts is an important MSSA predictor, but remains insufficient for the detection of MSSA in individual patients. The detection rate of the SRS and RES scales was also poor and could therefore not identify MSSA patients or be used to validate the CSRS-BP.

Behavioral, nutritional, and local risk factors for oral health are frequent in people with anorexia nervosa. However no self-report questionnaire is available for screening in clinical practice or for research purposes. The objective of this study was to design a questionnaire to identify risk factors and symptoms of oral diseases and to test its reliability as a self-report form among people with anorexia nervosa. A 26-item questionnaire was designed based on a sound literature review performed by a group of dentists, psychiatrists, and epidemiologists specialized in the field of eating disorders. Sixty-nine anorexia nervosa inpatients (mean age 18.72 ± 5.1) were included from four specialized units. The questionnaire was first self-reported by the patients, then the same questionnaire was administrated by a dentist during a structured face-to-face interview as the gold standard. The concordance between the two forms was evaluated globally and item per item using Cohen’s kappa statistical tests. The overall concordance between the self-report questionnaire and the face-to-face structured interview was 55%. Of the 26 items, 19 showed significant concordance. Items relating to water intake, extracted teeth, gingival status, and oral hygiene had the best concordance (all kappa coefficients > 0.4). A questionnaire that identifies risk factors and symptoms of oral diseases in anorexia nervosa was developed and tested. The 26-item form of the questionnaire (long version) is moderately reliable as a self-reported form. A short version of the questionnaire, including the 10 most reliable items, is recommended for oral risk assessment in patients with anorexia nervosa. The clinical value of the self-administered questionnaire remains to be evaluated.

Abstract. Background: Nonsuicidal self-injury (NSSI) is a strong predictor of suicide attempts (SA). Characteristics of NSSI have been shown to influence the NSSI–SA relationship; however, the temporal nature of this association is understudied. Aims: This study aimed to elucidate the NSSI-SA relationship by examining the association between NSSI characteristics and time lapsed from NSSI onset to first SA. Method: Participants were 111 individuals with a history of NSSI that preceded their first SA who completed a series of self-report measures. Results: NSSI methods of cutting and burning, and the anti-dissociation function, were associated with a shorter transition time from NSSI to SA. Earlier age of NSSI onset and the interpersonal boundaries function were related to a longer time to transition. Limitations: This sample size was limited, and data were collected cross-sectionally. Conclusion: Findings provide foundational knowledge regarding NSSI characteristics to inform theoretical models of the NSSI–SA association. This information can inform suicide risk assessments among those with a history of NSSI.

Strengths And Difficulties

Purpose The Strengths and Difficulties Questionnaire (SDQ) has been validated as a screening tool for identifying difficulties in adolescents in various countries. According to the results, the SDQ needs clinical evaluations to discriminate between adolescents with and without problems. This study is part of a research group that developed the self-report Indonesian version of the SDQ. Therefore, this study aims to evaluate the sensitivity and specificity of the self-report Indonesian version of the SDQ conduct problems subscale and identify the optimum cut-off score for Indonesian adolescents. Design/methodology/approach This study was a double-blind non-experimental study, in which the self-report SDQ score was compared to the diagnostic interview. Participants that completed the SDQ were 708 10th-grade students in Jakarta, with 40 students from the sample randomly selected through the double-blind technique for the diagnostic interview. Findings Crosstab’s analysis showed that the SDQ conduct problems subscale had a sensitivity value of 77.3% and a specificity value of 83.3%. Receiver operating characteristics analysis showed that the cut-off score of 4 used in this study is ideal for identifying individuals with conduct problems. Originality/value The SDQ has good accuracy for screening conduct problems among adolescents. Moreover, it will be helpful for parents, teachers, professionals and adolescents to screening conduct problems.

Abstract Background Sleep disturbance has been consistently identified as an independent contributor to suicide risk. Inflammation has emerged as a potential mechanism linked to both sleep disturbance and suicide risk. This study tested associations between sleep duration, insomnia, and inflammation on suicidal ideation (SI) and history of a suicide attempt (SA). Methods Participants included 2329 adults with current or remitted depression and/or anxiety enrolled in the Netherlands Study of Depression and Anxiety. Sleep duration, insomnia, past week SI, and SA were assessed with self-report measures. Plasma levels of C-reactive protein, interleukin-6, and tumor necrosis factor-α were obtained. Results Short sleep duration (⩽6 h) compared to normal sleep duration (7–9 h) was associated with reporting a prior SA, adjusting for covariates [adjusted odds ratio (AOR) 1.68, 95% CI 1.13–2.51]. A higher likelihood of SI during the past week was observed for participants with long sleep duration (⩾10 h) compared to normal sleep duration (AOR 2.22, 95% CI 1.02–4.82), more insomnia symptoms (AOR 1.44, 95% CI 1.14–1.83), and higher IL-6 (AOR 1.31, 95% CI 1.02–1.68). Mediation analyses indicated that the association between long sleep duration and SI was partially explained by IL-6 (AOR 1.02, 95% CI 1.00–1.05). Conclusions These findings from a large sample of adults with depression and/or anxiety provide evidence that both short and long sleep duration, insomnia symptoms, and IL-6 are associated with the indicators of suicide risk. Furthermore, the association between long sleep duration and SI may operate through IL-6.

The objective was to correct the self-reported prevalence of systemic arterial hypertension (SAH) obtained from the Brazilian National Health Survey (PNS 2013). SAH prevalence estimates were corrected by means of sensitivity/specificity of information. Sensitivity and specificity values from a similar study (same self-report question, age range and gold standard) were used to this end. A sensitivity analysis was also performed, by using the upper and lower limits of confidence intervals as sensitivity and specificity parameters. The corrected prevalence of SAH for Brazil as a whole was 14.5% (self-reported: 22.1%). Women presented a higher rate of self-reported SAH but, after correction, men were found to have a higher prevalence. Among younger women (18-39 age range), the self-reported prevalence was 6.2%, a value that, after correction, dropped to 0.28%. There was not much difference between self-reported and corrected SAH among the elderly (51.1% vs. 49.2%). For certain groups the corrected results were greatly different from the self-reported prevalence, what may severely impact public health policy strategies.

This study examines the sensitivity and specificity of a self-report screen for the diagnosis of migraine according to the IHS criteria in a sample of 1049 employees of the French National Railways. The diagnosis of migraine derived from the self-report instrument was compared to an unstructured diagnostic interview conducted by a neurologist specialized in the diagnosis and treatment of headache. The sensitivity of the diagnostic screen was poor, but the specificity was excellent. Optimal cut-off points for the questionnaire were determined by the Receiver Operator Characteristics (ROC) method. Assessment of the specific IHS criteria for migraine revealed that the following criteria failed to discriminate subjects with migraine from non-cases: “aggravation by physical activity” and “photophobia and phonophobia”. Implications of the findings for modification of the IHS criteria were discussed.

Cognitive Reflection

Ukraine has been the target of a long-running Russian disinformation campaign. We investigate susceptibility to this pro-Kremlin disinformation from a cognitive science perspective. Is greater analytic thinking associated with less belief in disinformation, as per classical theories of reasoning? Or does analytic thinking amplify motivated reasoning, such that analytic thinking is associated with more polarized beliefs (and thus more belief in pro-Kremlin disinformation among pro-Russia Ukrainians)? In online (N=1,974) and face-to-face representative (N=9,474) samples of Ukrainians, we find support for the classical reasoning account. Analytic thinking, as measured using the Cognitive Reflection Test, was associated with greater ability to discern truth from disinformation – even for Ukrainians who are strongly oriented towards Russia. We found similar, albeit somewhat weaker, results when operationalizing analytic thinking using the self-report Active Open-minded Thinking scale. These results demonstrate a similar pattern to prior work using American participants. Thus, the positive association between analytic thinking and the ability to discern truth versus falsehood generalizes to the qualitatively different information environment of post-communist Ukraine. Despite low trust in government and media, weak journalistic standards, and years of exposure to Russian disinformation, Ukrainians who engage in more analytic thinking are better able to tell truth from falsehood.

Accurate Identification

BackgroundDeveloping accurate identification methods for individuals with suicide attempts and providing them with follow-up care and supports can be a vital component of all comprehensive suicide prevention strategies. However, because of the difficulties concerning one’s intentions behind injurious behaviour, identifying suicide attempts is a challenge for families and clinicians.AimsThe aim of this study was to investigate the differences between family report and clinical assessment for suicide attempts in the emergency department (ED).MethodsA total of 148 patients with suspected suicide attempts (SSAs) and 148 family caregivers in the ED were enrolled. The suicide risk module of the Chinese version of the MINI International Neuropsychiatric Interview and the self-report measure were used to assess those with SSA’s suicidal behaviours. The Family Adaptability and Cohesion Evaluation Scales and semi-structured interviews were used to investigate the characteristics of suicide risk and demographics of patients with SSA, as well as the rate and influencing factors of omitted suicide attempts reported by family caregivers.ResultsThe underreporting rate for family reported suicide attempts in the ED was 69.0%. The suicide attempts group indicated lower mean scores on perceptions of family resources, adaptability and cohesion. Patients' suicide risk rating (OR =−1.81, 95% CI: −3.87 to −0.33, p=0.036), family satisfaction (OR =−1.11, 95% CI: −2.29 to −0.06, p=0.048), and caregiver’s age (OR =−1.68, 95% CI: −3.10 to −0.48, p=0.010) might be associated with underreporting by families. If patients committed suicide attempts through a falling injury or medication overdose, their families may have misreported the suicide attempt.ConclusionsThe discordance of suicide attempt records between family report and clinical assessment reveals the limitations of family self-reports when identifying suicide attempts. Interviews and observations, together with information from certain diagnoses, should be combined to accurately identify suicide attempters in the ED.

Neuroimaging, behavioral, and self-report evidence suggests that there are four main cognitive mechanisms that support mindfulness: (a) self-regulation of attention, (b) improved body awareness, (c) improved emotion regulation, and (d) change in perspective on the self. In this article, we discuss these mechanisms on the basis of the event-related potential (ERP). We reviewed the ERP literature related to mindfulness and examined a data set of 29 articles. Our findings show that the neural features of mindfulness are consistently associated with the self-regulation of attention and, in most cases, reduced reactivity to emotional stimuli and improved cognitive control. On the other hand, there appear to be no studies of body awareness. We link these electrophysiological findings to models of consciousness and introduce a unified, mechanistic mindfulness model. The main idea in this refined model is that mindfulness decreases the threshold of conscious access. We end with several working hypotheses that could direct future mindfulness research and clarify our results.

Mental Health Distress

Purpose The aim of this study was to examine the relationship between tinnitus and self-reported mental health distress, namely, depression symptoms and perceived anxiety, in adults who participated in the National Health and Nutrition Examinations Survey between 2009 and 2012. A secondary aim was to determine if a history of serving in the military modified the associations between tinnitus and mental health distress. Method This was a cross-sectional study design of a national data set that included 5,550 U.S. community-dwelling adults ages 20 years and older, 12.7% of whom were military Veterans. Bivariable and multivariable logistic regression was used to estimate the association between tinnitus and mental health distress. All measures were based on self-report. Tinnitus and perceived anxiety were each assessed using a single question. Depression symptoms were assessed using the Patient Health Questionnaire, a validated questionnaire. Multivariable regression models were adjusted for key demographic and health factors, including self-reported hearing ability. Results Prevalence of tinnitus was 15%. Compared to adults without tinnitus, adults with tinnitus had a 1.8-fold increase in depression symptoms and a 1.5-fold increase in perceived anxiety after adjusting for potential confounders. Military Veteran status did not modify these observed associations. Conclusions Findings revealed an association between tinnitus and both depression symptoms and perceived anxiety, independent of potential confounders, among both Veterans and non-Veterans. These results suggest, on a population level, that individuals with tinnitus have a greater burden of perceived mental health distress and may benefit from interdisciplinary health care, self-help, and community-based interventions.
