Reconsidering false positives in machine learning binary classification models of suicidal behavior

We posit the hypothesis that False Positive cases (FP) in machine learning classification models of suicidal behavior are at risk of suicidal behavior and should not be seen as sheer classification error. We trained an XGBoost classification model using survey data from 173,663 Norwegian adolescents and compared the classification groups for several suicide-related mental health […]

Can we notice the suicidal warning signs of adolescents with different psychometric profiles before their death? Analysis of teachers’ reports

Background: This study aimed to analyze the suicidal warning signs of Korean students with different psychometric profiles based on teacher reports. Methods: This was a retrospective cohort study based on Korean school teachers’ responses to the Student Suicide Report Form. In total, 546 consecutive cases of student suicide were reported from 2017 to 2020. After missing data […]

Assessing the reliability of the CAMS rating scale using a generalizability study

Background: An important consideration when conducting randomized controlled trials is treatment differentiation. Direct observation helps ensure that providers in different treatment groups are delivering distinct interventions. One direct observation method is the use of a measure to rate clinician performance when delivering an intervention. Aims: This generalizability study evaluated the reliability of the CAMS Rating Scale (CRS), a […]

Assessment of plasma-endogenous opioid neuropeptide levels and psychometric properties of non-suicidal self-injury in adolescents

Objective: Non-suicidal self-injury (NSSI) is one of the most common mental health problems and growing public-health issues, coupled with a significant population-level burden among adolescents in both developed and developing countries. We aimed to assess the role of endogenous opioid system-emotion regulation circuitry in NSSI through measurement of plasma beta-endorphin (β-EP), met-enkephalin (MENK) levels, and determination […]

Early adolescence and suicidal ideations in Croatia: Sociodemographic, behavioral, and psychometric correlates

Background/aims: Suicidal ideations (SI) indicate and predict psychological distress. We examined the prevalence of SI among early adolescents and its association with parental war participation, personal, behavioral, and sociodemographic characteristics. Methods: We performed a cross-sectional questionnaire study on 803 12-year-old adolescents. Data were collected using a sociodemographic questionnaire, the Junior Eysenck Personality Questionnaire and Children Depression Inventory. […]

Psychometric properties of two Arabic Suicide Scales: Stigma and literacy

Suicide is one of the leading causes of death. Suicide stigma and literacy may affect the rate of suicide and help-seeking behaviors. This study examined the psychometric properties of the Arabic version of the Stigma of Suicide Scale-short form (SOSS-SF) and Literacy of Suicide Scale (LOSS). The sample included 160 Jordanian university students. Reliability analysis showed acceptable Cronbach’s […]

Psychometric properties of the Bangla Brief Suicide Cognitions Scale among university level students

Objectives. Assessment of suicide cognition would help to measure the enduring suicide risk and to predict the risk of a suicide attempt. However, no previous attempt was identified to validate the suicide cognition scale in Bangla. We aimed to assess the psychometric properties of the Brief Suicide Cognitions Scale (BSCS) in Bangla. Methods. We conducted this […]

Psychometric properties of the Suicidal Ideation Scale in the Indonesian language

Introduction: Suicide is one of the leading cause of mortality among adolescents and young adults, especially in low to middle-income countries. Research found that screening for suicidal ideation in non-clinical populations such as schools or communities is an important step toward preventing suicide. Despite so, not all screening tools have the capabilities to accurately detect […]

Examining suicide assessment measures for research use: Using item response theory to optimize psychometric assessment for research on suicidal ideation in major depressive disorder

Introduction Progress reducing suicide death will require randomized clinical trials (RCTs) specifically targeting suicide risk. Even large RCTs may not stipulate suicide death as the primary outcome, as suicide death is relatively uncommon. Therefore, RCTs may need to specify suicidal ideation as a proxy indicator of risk. There is no consensus on the best tool […]

Validating the factor structure of the stigma of suicide scale: Short form Spanish version among healthcare students

Background: Suicide is a leading cause of death among Spanish-speaking individuals. Suicide stigma can be a risk factor for suicide. A widely used measure is the Stigma of Suicide Scale-Short Form (SOSS-SF; Batterham, Calear, & Christensen, 2013). Although the SOSS-SF has established psychometric properties and factor structure in other languages and cultural contexts, no evidence is available […]

Beliefs about one’s non-suicidal self-injury: The Experiences of Self-Injury Questionnaire (ESIQ)

Objective The goal of this study was to develop and validate a measure of self-rated positive and negative beliefs about one’s non-suicidal self-injury (NSSI), the Experiences of Self-Injury Questionnaire (ESIQ). Method Psychometric properties and validation against NSSI severity and shame were tested in two U.S. and two U.K. samples of individuals who endorsed a history […]

Psychometric properties of the clergy suicide prevention competencies developmental rubric and faith leaders’ readiness to address suicide stigma

Faith leaders (FL) have a key role in suicide prevention. One of their roles is to address suicide stigma in faith communities. Are they ready to do so? The Clergy Suicide Prevention Skills Developmental Rubric (CSPCDR) was developed to understand and assess clergy suicide prevention skills. The psychometric properties of the CSPCDR are reported in […]

An examination of the psychometric properties of the Reasons for Living Inventory within a male veteran clinical sample

Elevated suicide risk among veteran populations remains a significant public health concern. However, few suicide assessment measures have been validated for veterans. The current study evaluated the reliability and validity of the Reasons for Living Inventory (RFL) scores among veteran populations. The participants included male veterans (N = 421) from a broad range of ages, […]

A psychometric investigation of the painful and provocative events scale: Moving forward

Acquired capability for suicide is posited to develop through repeated exposure to physically painful and psychologically provocative events; however, there is limited research evaluating the assessment of painful and provocative events. The current study examined the factor structure, validity, and reliability of the Painful and Provocative Events Scale (PPES). Categorical exploratory and confirmatory factor analyses […]

Psychometric testing of immigrants and natives in an acute psychiatry facility.

The diagnostic process after referral to an acute psychiatric treatment facility consists of more than the clinical investigation and laboratory tests. Psychometric tests in a broad range of languages may be such an augmentation of our diagnostic armamentarium. Whether such tests are in use, and how they are distributed among different patient categories was the aim […]

Descriptive characteristics and initial psychometric properties of the non-suicidal self-injury disorder scale.

Non-suicidal self-injury (NSSI) is highly prevalent and associated with tissue damage, emotional distress, and psychiatric disorders. While often discussed in the context of Borderline Personality Disorder and suicide, research demonstrates that NSSI is distinct from these constructs and should be viewed as an independent diagnostic category. Recently, Non-Suicidal Self-Injury Disorder (NSSID) was included in the […]

Interpersonal and intrapersonal functions of deliberate self-harm (DSH): a psychometric examination of the inventory of statements about self-injury (ISAS) scale.

Deliberate self-harm (DSH), commonly defined as the intentional, direct and non-suicidal destruction of one’s body, appears to be common across both clinical and non-clinical populations. A recently developed measure of functions of DSH, the Inventory of Statements About Self-Injury (ISAS), was examined to test its two-factor model within a sample of members of online social […]
