Co-developmental trajectories of suicidal ideation and non-suicidal self-injury among Chinese adolescents: Transdiagnostic predictors and association with suicide attempts

Introduction Adolescent suicidal ideation (SI) and non-suicidal self-injury (NSSI) are crucial public health issues, yet their co-developmental trajectories during early adolescence and their associations with predictors and outcomes are unclear. This study aimed to (a) identify heterogeneous co-developmental trajectories of SI and NSSI, (b) explore associations between transdiagnostic predictors and trajectories, and (c) assess suicide […]

Adolescent nonsuicidal self-injury and suiciality: A latent class analysis and associations with clinical characteristics in an at-risk cohort

Nonsuicidal self-injury (NSSI) is frequently encountered in adolescents, but its predictive value for suicidality or other clinical characteristics is challenging due to its heterogeneous nature. This study used latent class analysis to identify subgroups of NSSI and compared these on sociodemographic characteristics, adverse outcomes and protective factors. The study included 966 high-risk adolescents, Mage 14.9 […]

Decoding suicide decedent profiles and signs of suicidal intent using latent class analysis

Importance  Suicide rates in the US increased by 35.6% from 2001 to 2021. Given that most individuals die on their first attempt, earlier detection and intervention are crucial. Understanding modifiable risk factors is key to effective prevention strategies. Objective  To identify distinct suicide profiles or classes, associated signs of suicidal intent, and patterns of modifiable risks for […]

Do bipolar disorder symptom profiles matter for suicide risk? A latent class approach to investigating differences in suicidal desire and acquired capability

Introduction Depressive and mixed symptoms in bipolar disorder (BD) have been linked to higher suicide risk. Based on Klonsky and May’s three-step theory and Joiner’s Interpersonal Psychological Theory of Suicide, we hypothesized that patients diagnosed with BD who reported severe levels of depressive symptoms and mixed depressive and manic symptoms would also report higher levels […]

The influence of childhood trauma and chronotype on suicide attempts in Chinese emerging adults with severe depressive symptoms

Background Studies have investigated how adults with severe depressive symptoms are more likely to attempt suicide, and these adults often have traumatic experiences and chaotic sleep/wake rhythms. Thus, this study using Latent class analysis aimed to investigate the relationship between childhood trauma class, chronotype, and suicide attempts among emerging adults with severe depressive symptoms. Methods […]

Characteristics of suicide attempts in Northwestern Iran: A five-year population-based survey

Background: Suicide is a serious public health problem in the world. This study aims to describe the characteristics of suicide attempters in North-Western Iran and identify latent classes of suicide attempts. Methods: This cross-sectional study was conducted in Ardabil Province (Northwest Iran) during 2017-2021 based on a registration system for suicide attempts. We performed latent class analysis […]

Generalisability of the interpersonal theory of suicide to latent profiles of young people attending treatment in a suicide prevention service

Objective: The Interpersonal Theory of Suicide (ITS) could help identify differences in groups of suicidal adolescents and inform treatment. Method: Latent Profile Analysis (LPA) using thwarted belongingness (TB), perceived burdensomeness (PB), hopelessness, and capability was conducted on data from an at-risk clinical sample (N = 500). The ITS prediction that changes in TB and PB are associated […]

Investigating the role of suicidality and ethnic identity among Black adolescents: A latent profile analysis

Objective: Suicide among Black adolescent youth has steadily increased in recent years, yet few studies describe how facets of social identity shape suicidal thoughts and behaviors (STBs) during this critical stage of development. Ethnic identity represents an underexplored, yet important element of social identity among Black youth that may contribute to differential associations with STBs. This […]

A multidimensional approach for differentiating the clinical needs of young people presenting for primary mental health care

Objectives There is an ongoing necessity to match clinical interventions with the multidimensional needs of young people. A key step toward better service planning and the design of optimal models of care is to use multidimensional assessment to understand the clinical needs of those presenting to primary mental health care. Methods 1284 people aged 12–25 years presenting to […]

High suicidality predicts overdose events among people with substance use disorder: A latent class analysis

Introduction: Suicide is the tenth leading cause of death in the United States and continues to be a major public health concern. Suicide risk is highly prevalent among individuals with co-occurring substance use disorders (SUD) and mental health disorders, making them more prone to adverse substance use related outcomes including overdose. Identifying individuals with SUD who […]

Nonmedical social determinants, syndemic conditions, and suicidal thoughts and behaviors in a treatment-seeking community sample: A latent class analysis

Objective: Knowledge gaps remain regarding whether syndemic conditions identify treatment-seeking individuals most at risk for suicidal thoughts and behaviors (STB). We employed latent class analysis to: (1) model treatment-seeking individuals’ syndemic conditions, (2) examine latent classes across nonmedical social determinants, and (3) assess associations between class membership and STB. Method: Participants were 982 individuals presenting at a […]

Heterogeneity of non-suicidal self-injury behavior in adolescents with depression: latent class analysis

Background Non-suicidal self-injury (NSSI) by adolescent patients with depression has become a serious public health problem. This cross-sectional study aims to identify subgroups of adolescents based on NSSI and explore the factors related to these subgroups. Methods The study recruited 326 in- and out-patient adolescents (263 girls and 63 boys) aged 12 to 18 years […]

Investigation of the subtypes of nonsuicidal self-injury based on the forms of self-harm behavior: Examining validity and utility via latent class analysis and ecological momentary assessment

Background: This study aimed to empirically derive and validate subtypes of nonsuicidal self-injury (NSSI) based on the forms of self-harm behavior. Methods: Sixty young adults who exhibited repetitive NSSI completed a clinical interview and baseline measures, followed by a two-week ecological momentary assessment (EMA). A latent class analysis was administered to identify NSSI subtypes based on the […]

Gender differences in suicide rates of municipalities in South Korea: A latent profile analysis by life cycles

Background: South Korea showed the highest suicide rate among the countries in the Organization for Economic Cooperation and Development. Aims: This study aimed to discern the profiles of municipalities according to their suicide rates across the life cycle and gender, and then to identify the unique characteristics of each latent group. Method: This study applied a latent profile modeling to […]

Suicide risk among veterans using VHA justice-involved services: A latent class analysis

Background Justice-involved Veterans experience notable risk for psychosocial stressors (e.g., homelessness) and psychiatric multimorbidity, which can result in complex clinical presentations. However, research examining how such factors coalesce to impact risk for suicide remains limited. Methods We conducted a latent class analysis of 180,454 Veterans accessing Veterans Health Administration (VHA) justice-related services from 2005 to […]

An empirical investigation of the distinction between passive and active ideation: Understanding the latent structure of suicidal thought content

Introduction Although the distinction between passive and active suicidal ideation is well accepted by suicide researchers and clinicians, there has been very little empirical investigation into this distinction. The current study addressed this gap by examining the latent structure of suicidal ideation based on thought content. Method Participants from two distinct samples of U.S. adults […]
