Development and validation of the self-injury stigma scale. J Psychiatr Res 2024; 173:48-57. [PMID: 38484618 DOI: 10.1016/j.jpsychires.2024.02.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 09/27/2023] [Accepted: 02/07/2024] [Indexed: 04/17/2024]
Abstract
Non-suicidal self-injury is a prevalent and concerning behavior. Negative beliefs and stereotypes about NSSI are associated with negative outcomes, and negative, self-referential beliefs (e.g., self-stigmatizing beliefs) related to engagement in NSSI may be particularly harmful. Despite this, there is no validated measure specifically designed to assess for NSSI self-stigma. As this significantly hinders the ability to understand and quantify the effect of NSSI self-stigma, this study sought to validate the newly developed Self-Injury Stigma Scale (SISS). It was hypothesized the SISS would follow a four-factor structure that parallels a widely cited theoretical model of stigma. It was also hypothesized measures of shame and help-seeking self-stigma would be moderately, negatively, correlated with the SISS subscales, supporting the measure's validity. Participants from Study 1 were college students (n = 264, 65.8% female) with at least one lifetime NSSI act. A series of factor analytic models revealed a one-factor structure for the Application of Stigma subscale (i.e., third step of the four-step model). As this was the only SISS subscale to achieve an appropriate model fit, this scale alone was retained as the final SISS. The factor structure was tested via confirmatory factor analysis on a second sample (i.e., community participants with at least one past month of NSSI act; n = 240, 41.3% female). An acceptable fit on most, but not all, indices was reached. Convergent and discriminant validity were supported. The SISS retrospectively predicted past 3 month NSSI frequency and method versatility, and lifetime NSSI versatility, but not lifetime NSSI frequency or disclosure. Thus, the clinical utility of the SISS was partially supported. Findings offering evidence in favor of the SISS's appropriateness and utility as a measure of self-stigma of NSSI. Future work using this measure has the potential to clarify the risk associated with NSSI self-stigma and inform behavioral interventions.

On the Selection of Item Scores or Composite Scores for Clinical Prediction. MULTIVARIATE BEHAVIORAL RESEARCH 2024:1-18.

Abstract
Recent shifts to prioritize prediction, rather than explanation, in psychological science have increased applications of predictive modeling methods. However, composite predictors, such as sum scores, are still commonly used in practice. The motivations behind composite test scores are largely intertwined with reducing the influence of measurement error in answering explanatory questions. But this may be detrimental for predictive aims. The present paper examines the impact of utilizing composite or item-level predictors in linear regression. A mathematical examination of the bias-variance decomposition of prediction error in the presence of measurement error is provided. It is shown that prediction bias, which may be exacerbated by composite scoring, drives prediction error for linear regression. This may be particularly salient when composite scores are comprised of heterogeneous items such as in clinical scales where items correspond to symptoms. With sufficiently large training samples, the increased prediction variance associated with item scores becomes negligible even when composite scores are sufficient. Practical implications of predictor scoring are examined in an empirical example predicting suicidal ideation from various depression scales. Results show that item scores can markedly improve prediction particularly for symptom-based scales. Cross-validation methods can be used to empirically justify predictor scoring decisions.

Characteristics and Functions of Non-Suicidal Self-Injury That Inform Suicide Risk. Arch Suicide Res 2024:1-14. [PMID: 38314767 DOI: 10.1080/13811118.2024.2310556] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/07/2024]
Abstract
OBJECTIVE Although non-suicidal self-injury (i.e., NSSI) has been suggested as a robust risk factor of suicide, NSSI related information that is most related to suicide risk remains unclear. Commonly studied NSSI characteristics are its frequency and the number of methods endorsed. However, it may not be merely how frequent or how many different methods that matters, but "why," which alludes to the importance of NSSI functions (or why individuals engage in NSSI). Thus, this study examined how the interactions between NSSI characteristics and functions are associated with suicide risk. METHODS Undergraduate students (n = 820) with a lifetime history of NSSI, filled out self-report measures on NSSI and suicide risk. A hierarchical regression analysis was conducted to examine the moderation effects between four 2-way interactions (i.e., method X intrapersonal; method X interpersonal; frequency X intrapersonal; frequency X interpersonal) on suicide risk. RESULTS Main effects of all four independent variables were statistically significant. In terms of interactions, the intrapersonal function moderated both the effects of NSSI frequency and methods on suicide risk, whereas the interpersonal function moderated the effects of NSSI frequency on suicide risk. CONCLUSION Our results highlight that some NSSI related information than others are more indicative of suicide risk. In particular, the combination of NSSI functions, along with its frequency and number of methods, holds promise when assessing for current and lifetime suicidal thoughts and behaviors.

Nonsuicidal self-injury characteristics: A mixed methods analysis of differences between veterans and civilians. J Psychiatr Res 2023; 168:318-324. [PMID: 37949043 DOI: 10.1016/j.jpsychires.2023.10.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 08/31/2023] [Accepted: 10/25/2023] [Indexed: 11/12/2023]
Abstract
Nonsuicidal self-injury (NSSI) is a well-established risk factor for suicidal behavior, with certain NSSI characteristics being associated with increased risk. In the United States (U.S.), the veteran suicide rate is elevated, though lifetime prevalence rates of NSSI appear similar between veterans and civilians. There is limited research that directly compares veterans and civilians across multiple NSSI characteristics to examine between-group differences in NSSI behavior and provide important context for the application of NSSI research with the veteran population. This study examined differences between U.S. veterans and civilians with a history of suicidal ideation across several NSSI characteristics, including method, severity, age of onset, shame, distress, and reason for initial NSSI engagement. A sample of 527 veterans and civilians completed measures of direct and indirect NSSI behaviors along with supplemental questions designed to further assess endorsed NSSI behaviors. Additionally, respondents provided written responses to an open-ended question about their reasons for initial engagement in NSSI, which were coded for post-hoc analysis. Chi-square difference tests and t-tests were conducted, revealing significant group differences between veterans and civilians in NSSI method, lifetime versatility, age of onset, age at last occurrence, and reasons for initial engagement. No significant differences were found in NSSI frequency, severity, shame, or distress. These findings provide valuable information on similarities and differences in NSSI behavior characteristics between U.S. veterans and civilians with lifetime suicidal ideation to inform future research and the assessment of NSSI in these populations.

Abstract
INTRODUCTION Nonsuicidal self-injury (NSSI) is a prevalent and concerning behavior and its risk pathways require a greater understanding, particularly in predicting short-term risk. Although the literature has supported a between-person link among NSSI and alcohol use, limited research has directly examined the nuances of this relationship at the within-person level using intensive longitudinal data. METHOD Utilizing two independent samples (total n = 85), the current study examined bidirectional, concurrent and prospective risk relationships between NSSI and alcohol, considering both urges and behavior engagement, via ecological momentary assessment. RESULTS Findings demonstrate concurrent, within-person relationships between NSSI urges and alcohol urges, as well as alcohol use. Alternatively, prospective between-person findings demonstrated negative relationships between NSSI urges and alcohol use, as well as alcohol urges and NSSI acts; however, this may represent suppression effects as associations were positive with the removal of autoregressive effects. CONCLUSIONS Together, findings support proximal risk relationships between NSSI and alcohol experiences that, for urges in particular, is bidirectional.

Abstract
ABSTRACT This study examined the differences in negative beliefs about disclosing suicidal thoughts and behaviors (STBs) between US Veterans and non-Veterans, and between Veterans who are and are not enrolled in Veterans Health Administration (VHA) care. Participants included 495 adults with a history of suicide ideation who completed an online self-report questionnaire inquiring about history of STBs, STB disclosure, and beliefs about STB disclosures. Group differences in STB disclosure beliefs were analyzed. Results showed that Veterans (vs. non-Veterans) more strongly believed that STB disclosure would result in firearm confiscation. VHA-enrolled (vs. non-VHA enrolled) Veterans reported stronger beliefs that STB disclosures result in involuntary hospitalization. Among VHA-enrolled Veterans, stronger beliefs regarding providers' interest regarding true STB experiences and others' comfort with STB disclosures were associated with lower STB disclosure likelihood. Findings highlight that educating Veterans on the benefits of STB disclosure and limiting misinformation regarding its consequences is paramount, specifically through improved suicide-related communication within the VHA and stigma reduction campaigns.

Abstract
The present study aimed to expand the literature on single-item assessments for suicidal thoughts and behaviors (STBs) by examining measurement invariance of commonly used single-item assessments of suicidal ideation (SI), planning (SP), and attempts (SA) with respect to race and ethnicity. Predictive invariance with respect to depression, and multi-item measures of passive and active SI were also explored. Measurement invariance was examined across (a) Black and White respondents and (b) Hispanic/Latinx and non-Hispanic/-Latinx respondents. Participants (N = 1,624; 51.66% male) were recruited from Mechanical Turk and Prime Panels. Participants were administered four distinct single-item measures each for SI, SP, and SA across three timeframes (past month, past year, lifetime). Items were drawn from well-known large-scale studies (e.g., National Comorbidity Survey) and common suicide risk assessments. Multiple group confirmatory factor analysis was used to examine measurement invariance; regression with group by measure interactions were used to evaluate predictive invariance. Measurement invariance was observed for both Black (N = 534) and White (N = 1,089) respondents as well as Hispanic/Latinx (N = 335) and non-Hispanic/-Latinx (N = 1,288) respondents across single-item outcomes. Thus, SI, SP, and SA rates can be defensibly compared between Black and White and Hispanic/Latinx and non-Hispanic/-Latinx respondents within studies; however, comparison of SI and SP rates across studies with differing assessment prompts should be met with caution. Multiple single-item STB measures demonstrated predictive bias across race and ethnicity suggesting potential differential screening capabilities. Elevated SI, SP, and SA rates for Hispanic/Latinx individuals were also observed. Findings reiterate the importance of minor language differences in single-item STB assessments.

Abstract
Text is a burgeoning data source for psychological researchers, but little methodological research has focused on adapting popular modeling approaches for text to the context of psychological research. One popular measurement model for text, topic modeling, uses a latent mixture model to represent topics underlying a body of documents. Recently, psychologists have studied relationships between these topics and other psychological measures by using estimates of the topics as regression predictors along with other manifest variables. While similar two-stage approaches involving estimated latent variables are known to yield biased estimates and incorrect standard errors, two-stage topic modeling approaches have received limited statistical study and, as we show, are subject to the same problems. To address these problems, we proposed a novel statistical model-supervised latent Dirichlet allocation with covariates (SLDAX)-that jointly incorporates a latent variable measurement model of text and a structural regression model to allow the latent topics and other manifest variables to serve as predictors of an outcome. Using a simulation study with data characteristics consistent with psychological text data, we found that SLDAX estimates were generally more accurate and more efficient. To illustrate the application of SLDAX and a two-stage approach, we provide an empirical clinical application to compare the application of both the two-stage and SLDAX approaches. Finally, we implemented the SLDAX model in an open-source R package to facilitate its use and further study. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Abstract
While predominant suicide theories emphasize the role of social connectedness in suicidal thinking, there is a need to better understand (a) how specific aspects of social connection relate to suicidal ideation and (b) the timeframe over which these relationships persist. The current study examined ecological momentary assessment data over a 30-day period from 35 participants with past-year suicidal thoughts or behaviors (mean age = 25.88; 62.9% women; 68.6% White) to address these questions. Results demonstrated that absence of social contact was associated with next timepoint suicidal ideation, even after considering the suicidal ideation autoregressive effect (i.e., concurrent), with effects strongest in the short-term. Findings provide preliminary evidence of the need to assess for the presence of social contact, and for assessments to occur in close proximity (i.e., a few hours), to capture the true dynamics of risk for suicidal ideation. Although needing replication, results suggest importance of just-in-time interventions targeting suicidal ideation.

Abstract
BACKGROUND Both internet addiction (IA) and non-suicidal self-injury (NSSI) are major public health concerns among adolescents, however, the association between IA and NSSI was not well understood. We aimed to investigate the association between IA and NSSI within a cohort study, and explore the mediated effect of depressive symptoms and the moderating effect of social support in the association. METHODS A total of 1530 adolescents aged 11-14 years who completed both the baseline (T1) and 14-month follow-up (T2) survey of the Chinese Adolescent Health Growth Cohort were included for the current analysis. IA, NSSI, depressive symptoms and social support were measured at T1; depressive symptoms and NSSI were measured again at T2. Structural equation models were employed to estimate the mediated effect of depressive symptoms and the moderating effect of social support in the association between IA and NSSI at T2. RESULTS IA was independently associated with an increased risk of NSSI at T2, with the total effect of 0.113 (95%CI 0.055-0.174). Depressive symptoms mediated the association between IA and NSSI at T2, and social support moderated the indirect but not the direct effect of IA on NSSI at T2. Sex differences were found on the mediated effect of depressive symptoms and the moderated mediation effect of social support. CONCLUSIONS Interventions that target adolescents' NSSI who also struggle with IA may need to focus on reducing depressive symptoms and elevating social support.

For Better or Worse?: The role of cognitive flexibility in the association between nonsuicidal self-injury and suicide attempt. J Psychiatr Res 2023; 158:157-164.

Abstract
Nonsuicidal self-injury (NSSI) has been repeatedly associated with increased suicide risk. However, the transition from NSSI to suicidal thoughts and behaviors still remains as an enigma. One possible construct that may influence this relationship is cognitive flexibility, which refers to the ability to adapt responses/strategies based on environmental feedback. It may be that greater cognitive flexibility increases one's cognitive accessibility to suicide, making it a more viable option upon distress especially for those with a prior history of NSSI. Conversely, it may be that less cognitive flexibility creates a negative bias that exacerbates the effects of NSSI on suicide. Thus, in this study, we examined how NSSI characteristics (i.e., frequency and methods) interact with cognitive flexibility to predict lifetime suicide attempt (SA) history. Participants were 505 individuals with a lifetime history of NSSI who completed a survey assessing for their NSSI experiences, cognitive flexibility, and SA history. Moderation analyses were conducted while controlling for sexual orientation, which significantly predicted SA history. Results indicated a significant interaction between number of NSSI methods endorsed and cognitive flexibility. In particular, individuals were more likely to have had a history of SA if they scored higher on the alternative subscale of cognitive flexibility. The results suggest that the adaptive value of cognitive flexibility may be context dependent, and highlight the importance of personalized care among those who engage in self-harm.

Abstract
INTRODUCTION People who identify as sexual minorities are at increased risk for suicide. Non-suicidal self-injury (NSSI) is also a risk factor for suicide and NSSI severity may contribute to development of capability for lethal self-injury. Further research is needed to understand how NSSI severity increases suicide risk, specifically in high-risk populations like sexual minorities. The current study seeks to examine whether sexual minority adults exhibit greater NSSI severity and suicide risk than heterosexuals, and if NSSI severity moderates the relationship between sexual orientation and suicide risk. METHODS Undergraduate students (N = 1,994) who reported five or more acts of NSSI in their lifetime completed online self-report questionnaires including sexual orientation, NSSI severity, and suicide risk. RESULTS A factorial ANOVA demonstrated main effects of sexual orientation and NSSI severity on suicide risk. DISCUSSION The lack of significant interaction effect indicates NSSI severity does not amplify the effect of on sexual orientation on suicide risk; rather, it predicts the same level of increased risk across orientations. Therefore, suicidality related to both sexual orientation and NSSI severity are equally important treatment targets.

Abstract
Background: Interpersonal problem-solving difficulties constitute a suicide risk factor that may be particularly relevant among college students. Most studies have examined general interpersonal problem-solving; however, context-specific abilities may have greater clinical implications. Aim: This study examined whether individuals with and without a history of suicidal thoughts and behaviors differed in context-specific interpersonal problem-solving. Method: Undergraduate students (n = 112) completed a brief interview and interpersonal problem-solving tasks with positive (e.g., initiating romantic relationship) and negative (i.e., physical revenge) resolutions. Results: Individuals with a history of suicide ideation generated more effective solutions and more alternatives in the negative-resolution scenario; no significant differences were identified for the positive-resolution scenarios. No group differences were found based on suicide attempt status. Limitations: Our results do not account for the mechanisms that influence problem-solving abilities in negative-resolution scenarios. Conclusion: Clinical efforts may benefit from targeting the translation of interpersonal problem-solving abilities to situations with positive resolutions.

Abstract
BACKGROUND Substance use and suicide ideation are common behaviors that often overlap among college students. However, clues about their temporal relationship, as well as moderating factors (e.g., distress, peer perceptions of substance use), are understudied. Indeed, those with a history of suicide ideation may use avoidance coping (including substance use) to manage distress, underscoring the possibility of substance use as a response to suicide ideation, an oft-stressful experience in and of itself. Further, as a low sense of belongingness confers risk for suicide ideation, distress may increase compliance with perceived cultural norms, thus increasing substance use behavior. This study examined the effect of the suicide ideation-distress-peer perception interaction on substance use. METHOD Participants were 3,608 undergraduate students across eleven college campuses. Measures of past month substance use frequency, general distress, peer perceptions of substance use, and past year suicide ideation were utilized. RESULTS Suicidal ideation was associated with e-cigarette, marijuana, and illicit drug use. There were main effects of suicide ideation (on e-cigarette and marijuana use) and peer perceptions of substance use (on tobacco, alcohol, e-cigarette, and marijuana use), but not distress, on past 30-day substance use. Further, the three-way interaction of suicide ideation, distress, and peer perceptions of substance use predicted frequency of past month tobacco and illicit drug use. CONCLUSIONS Suicide ideation may be temporally linked to use of specific substances. Peer perception and distress may strengthen the suicide ideation-substance use relationship. These factors should be carefully considered when treating individuals with substance use.

Abstract
OBJECTIVE The Interpersonal Theory of Suicide has been foundational in guiding current suicide literature. Despite recent research underscoring fluctuations of suicidal ideation within hours, there have been few studies examining the key constructs of perceived burdensomeness and thwarted belongingness within an intensive framework. Thus, the current study aimed to add cumulative knowledge regarding the within-person relationship between perceived burdensomeness, thwarted belongingness, and active suicidal ideation as assessed within an ecological momentary assessment design. METHOD A final sample of 35 individuals with a past-year history of suicidal thoughts or behaviors completed brief surveys four times per day for 30 days. RESULTS Findings highlighted that the addition of covariates may offer small improvements in modeling subsequent suicidal ideation, while controlling for SI at the prior time. Further, both thwarted belongingness and perceived burdensomeness were associated with next timepoint suicidal ideation, and their interaction added little incremental value. CONCLUSION Findings demonstrate the potential importance of thwarted belongingness in predicting suicidal ideation. Further, results highlight that the main effects of thwarted belongingness and perceived burdensomeness, rather than their interaction, may be more important to consider in relation to active suicidal ideation.

Abstract
Psychopathology is a common element of the human experience, and psychological scientists are not immune. Recent empirical data demonstrate that a significant proportion of clinical, counseling, and school psychology faculty and graduate students have lived experience, both past and present, of psychopathology. This commentary compliments these findings by leveraging the perspectives of the authors and signatories, who have personal lived experience of psychopathology, to improve professional inclusivity in these fields. By "coming out proud," the authors aim to foster discussion, research, and inclusion efforts as they relate to psychopathology experiences in psychological science. To that end, the authors describe considerations related to disclosure of lived experience, identify barriers to inclusion, and provide concrete recommendations for personal and systemic changes to improve recognition and acceptance of psychopathology lived experience among psychologists.

Abstract
OBJECTIVES Despite its importance, limited work has investigated the nuances of suicidal thoughts and behavior self-disclosure. The present study aimed to examine potential differences in self-disclosure based on whether an individual has disclosed suicidal thinking versus behavior. METHODS Two hundred and four participants having disclosed their suicidal thoughts or behaviors completed a battery of online questionnaires assessing several key aspects of disclosure (i.e., disclosure recipient, perceived helpfulness of disclosure, impact on treatment seeking), as it pertained to both one's first and overall disclosure experiences. RESULTS Individuals who disclosed a suicide attempt, versus ideation, were more likely to have disclosed to a formal support (i.e., health professional) and to seek professional help following disclosure. No significant group differences in perceived helpfulness of experiences were found. CONCLUSION It may be beneficial to increase opportunities for disclosure of suicidal thinking. Overall, disclosures were perceived as helpful and may not impede future help-seeking behavior.

[PMID: 35150977 DOI: 10.1016/j.psychres.2022.114408] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 01/15/2022] [Accepted: 01/19/2022] [Indexed: 10/19/2022]
Abstract
Widespread attempts to implement suicide prevention efforts may be hindered by stigma regarding suicidal thoughts and behaviors (STBs). Despite extensive literature linking general mental health stigma to numerous negative outcomes (i.e., reduced help-seeking), limited research has extended findings to STB-specific stigma. Thus, the present study aimed to examine the association between three types of STB stigma (public, self, and anticipated) and self-disclosure, a specific form of help-seeking for some individuals, among civilians and a population at heightened suicide risk, U.S. veterans. Participants (n = 500) reported a lifetime history of suicidal ideation (n = 253 identified as a U.S. veteran; n = 132 reported being enrolled in Veteran Health Administration [VHA] care) who completed self-report measures about their STB experiences, including stigma and self-disclosure. Results highlighted a significant association between greater self-stigma, as well as greater anticipated stigma, and a reduced likelihood of STB disclosure, among veterans but not civilians. No significant associations as a result of VHA care status were found. Together, findings suggest that individuals' concerns related to STBs and STB disclosure may be grounded in past experiences in the military, and thus highlight the need for prevention efforts that protect against negative consequences related to STB disclosure.

Using intensive time sampling methods to capture daily suicidal ideation: A systematic review. J Affect Disord 2022; 299:108-117. [PMID: 34718039 DOI: 10.1016/j.jad.2021.10.121] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Accepted: 10/25/2021] [Indexed: 10/20/2022]
Abstract
INTRODUCTION There has been an increased emphasis on understanding suicidal thoughts and behaviors as they occur in real-time, resulting in a proliferation of studies utilizing intensive time sampling methods. Given the continued growth in this area, there is a need to synthesize the feasibility of these methods in capturing suicidal ideation at the daily level, in addition to an examination of study factors that may impact suicidal ideation detection, to guide future research. METHOD Online databases (i.e., PsychINFO, ERIC, PubMed, MEDLINE) were systematically searched for articles published through December 2020 that assessed suicidal ideation at the daily level. RESULTS Twenty-six articles presenting data from sixteen independent datasets met inclusion criteria. Across included articles, suicidal ideation detection ranged from approximately 1-92% of participant-completed surveys, with 18-100% of unique study participants reporting suicidal ideation during the study period. Assessment-based factors (i.e., number of daily assessments, duration of daily assessment period) did not appear to be meaningfully associated with suicidal ideation detection rates. Rather, participant characteristics (i.e., baseline suicide risk history, inclusion criteria) were better indicators of a study's ability to capture suicidal ideation at the daily level. CONCLUSIONS Findings highlights the impact of targeting participants with elevated suicide risk at study enrollment.

Examining momentary associations between behavioral approach system indices and nonsuicidal self-injury urges. J Affect Disord 2022; 296:244-249. [PMID: 34619451 PMCID: PMC9022186 DOI: 10.1016/j.jad.2021.09.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 08/05/2021] [Accepted: 09/12/2021] [Indexed: 01/03/2023]
Abstract
BACKGROUND The current study aimed to examine the concurrent and prospective relationships between the three hypothesized components of behavioral approach system (BAS) sensitivity: drive, reflecting the motivation to pursue one's desired goals; reward responsiveness, reflecting sensitivity to reward or reinforcement; and fun-seeking, reflecting the motivation for pursuing novel rewards in a spontaneous manner, and NSSI urge severity. METHODS A sample of 64 undergraduates with a history of repetitive NSSI completed an ecological momentary assessment protocol. During this period of time, participants reported on the BAS-constructs of drive, reward responsiveness, and fun-seeking, as well as NSSI urge severity on a momentary basis at three random intervals each day for a period of ten-days. RESULTS Drive and reward responsiveness, but not fun-seeking, were concurrently positively associated with NSSI urge severity. However, no associations between BAS facets and prospective NSSI urges were found. LIMITATIONS This study was limited by its use of single items to assess the BAS-constructs of drive, reward responsiveness, and fun-seeking. CONCLUSIONS Our findings indicate that feeling strongly impacted by rewards and having a strong sense of drive toward goal attainment may represent cognitive risk states that are associated with increased within-person NSSI risk. However, their lack of prospective prediction may suggest that these cognitive states are associated only on a momentary basis with NSSI urges and may not confer risk.

Abstract
Borderline personality disorder (BPD) symptoms and suicidal behaviors are prevalent among undergraduate students. Although rumination contributes to self-destructive behaviors in BPD, less research examines the role of rumination in distinct suicidal outcomes among individuals with BPD features instead focusing more on self-destructive behaviors as a latent variable. The present study examined the main and interactive effects of BPD features and two forms of rumination (brooding and anger) in the prediction of suicide-related outcomes (ideation and attempts) among college students. Participants (N = 181 undergraduate students, overrecruited for BPD features; 55.2% female) reported their lifetime suicide risk, brooding rumination, anger rumination, and BPD features. Brooding rumination and BPD features were associated with suicidal ideation. Anger rumination was not associated with suicide-related outcomes. Findings suggest that brooding rumination is a potential intervention target for suicidal ideation in undergraduate students whereas further research is required to determine the association between anger rumination and suicidal ideation and attempts.

An experimental examination of interpersonal problem-solving in nonsuicidal self-injury: A pilot study. J Psychiatr Res 2021; 144:146-150. [PMID: 34628275 PMCID: PMC8817559 DOI: 10.1016/j.jpsychires.2021.09.005] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Revised: 06/23/2021] [Accepted: 09/01/2021] [Indexed: 10/20/2022]
Abstract
Nonsuicidal self-injury (NSSI) typically occurs in the presence of negative emotions. Prior research has emphasized interpersonal stress as a specific context that may elevate negative emotions in this population and even increase the likelihood of NSSI behavior. However, the factors that contribute to the relationship between interpersonal stress and NSSI have received relatively limited attention. The current pilot study aimed to experimentally examine interpersonal problem-solving as a potential moderator of the interpersonal stress - NSSI risk relationship among those with a NSSI history. Eighty-six participants (52.3% with NSSI history) were randomly assigned to one of three mood induction conditions (interpersonal negative, general negative, interpersonal neutral), after which they completed an interpersonal problem-solving task and a laboratory analogue of self-injurious behavior. Results indicated that NSSI history was associated with poorer interpersonal effectiveness. Further, individuals with a history of NSSI who experienced an interpersonally-focused negative mood and produced less effective interpersonal solutions were more self-harming on a laboratory analogue of self-injurious behavior. While the present findings are preliminary in nature, they offer guidance for research moving forward and, if replicated, suggest interpersonal problem-solving as a potential treatment target among individuals engaging in NSSI.

How we ask matters: The impact of question wording in single-item measurement of suicidal thoughts and behaviors. Prev Med 2021; 152:106472. [PMID: 34538365 DOI: 10.1016/j.ypmed.2021.106472] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2020] [Revised: 02/18/2021] [Accepted: 02/20/2021] [Indexed: 11/25/2022]
Abstract
The present study aimed to extend prior literature on single-item assessment by examining response consistency (1) between several commonly used single-item assessments of suicidal ideation, planning, and attempts, and (2) across three timeframes (past month, past year, and lifetime) commonly employed in the literature. Participants (N = 613) were recruited from an online community, Amazon Mechanical Turk (mTurk). Participants were administered three sets of four distinct single-items assessing suicidal ideation, suicidal planning, and suicide attempt history, respecitvely. Items were drawn from well-known large-scale studies (e.g., National Comorbidity Survey; World Health Organization Mental Health Survey Initiative, Youth Risk Behavior Survey) and commonly used suicide risk assessments (i.e., Self-Injurious Thoughts and Behaviors Interview). Through examinations of intraclass correlations and confirmatory factor analyses, findings suggested mixed response agreement across most outcomes and timeframes. Response inconsistency among items assessing suicidal ideation and among items assessing suicidal planning were partly attributed to minor, yet important, language differences. Given findings that even minor language changes in suicidal ideation and planning items may inflate or restrict prevalence estimates in a meaningful way, it will be important for researchers and clinicians alike to pay close attention to the wording of single items in designing research studies, interpreting findings, and assessing patient risk.

Abstract
IMPORTANCE The labor migration of parents in China often leaves children behind, which may be adversely associated with children's health. However, few studies have assessed the association of parental migration with nonsuicidal self-injury (NSSI) or with suicidality among their offspring. OBJECTIVE To examine the associations of parental labor migration with NSSI and with suicidality as well as potential differential associations by sex among offspring left behind. DESIGN, SETTING, AND PARTICIPANTS This nationwide cross-sectional study was conducted from February to October 2015 among individuals aged 11 to 20 years from 45 public middle and high schools across 5 provinces of China. Data analysis was performed from November 1, 2020, to March 1, 2021. EXPOSURES Parental labor migration, including parental migration status (yes vs no), migration pattern (father, mother, or both), and the child's age at the initial parent-child separation. MAIN OUTCOMES AND MEASURES Less frequent (1-4 episodes) NSSI, more frequent (≥5 episodes) NSSI, suicidal ideation, and suicide attempt in the past year were measured using validated questionnaires. Multinomial or binomial logistic regression analyses were used separately to estimate adjusted odds ratios (aORs) and 95% CIs of the associations between parental migration and NSSI, suicidal ideation, or suicide attempt. Potential covariates (demographic, family-level, and psychological characteristics) were adjusted for in 3 sequential models. RESULTS A total of 15 312 participants (7904 male [51.6%] and 7408 female [48.4%]) aged 11 to 20 years (mean [SD] age, 15.1 [1.8] years) were included. Of those participants, 5963 (23.3%) experienced parental migration. The 12-month prevalence of less frequent NSSI was 17.2% (2635 of 15 312), the 12-month prevalence of more frequent NSSI was 11.6% (1783 of 15 312), the 12-month prevalence of suicidal ideation was 15.2% (2335 of 15 312), and the 12-month prevalence of suicide attempt was 3.5% (535 of 15 312). Parental migration was associated with less frequent NSSI (adjusted odds ratio [aOR], 1.13; 95% CI, 1.03-1.24); no significant association of parental migration with more frequent NSSI (aOR, 1.01; 95% CI, 0.90-1.13), suicidal ideation (aOR, 1.00; 95% CI, 0.90-1.10), or suicide attempt (aOR, 1.09; 95% CI, 0.90-1.33) was identified. Compared with children whose parents did not migrate, the aOR for less frequent NSSI for participants whose father migrated was 1.18 (95% CI, 1.06-1.31), and the aOR for less frequent NSSI for participants having both parents migrate was 1.12 (95% CI, 1.01-1.28). Compared with children whose parents did not migrate, participants who experienced initial separation from 1 or both parents at preschool age had an aOR for less frequent NSSI of 1.16 (95% CI, 1.03-1.31). No sex disparities were found in these associations except for participants who experienced initial separation from 1 or both migrant parents at preschool age, for which the aOR for more frequent NSSI was higher among male (aOR, 1.27; 95% CI, 1.04-1.55) than female (aOR, 0.96; 95% CI, 0.77-1.19) participants. CONCLUSIONS AND RELEVANCE This cross-sectional study found that parental migration, mainly of the father or of both parents, or an initial separation of children at preschool age from 1 or both parents who migrated was associated with higher odds of experiencing 1 to 4 NSSI episodes in 1 year among offspring. Overall, the associations of parental migration with NSSI and suicidality were similar between male and female participants.

Abstract
BACKGROUND The COVID-19 pandemic has spurred the implementation of several public safety measures to contain virus spread, most notably socially distancing policies. Prior research has linked similar public safety measures (i.e., quarantine) with suicide risk, in addition to supporting the role of social connection in suicidal thoughts and behaviors; consequently, there is a need to better understand the relationship between widespread social distancing policies and suicide risk. The current study aimed to examine the prospective association between COVID-19-related social distancing practices and suicidal ideation. METHODS Participants (N = 472) completed measures of suicidal ideation and impacts of social distancing practices at baseline and two weeks later. RESULTS After controlling for general psychosocial distress (i.e., depression, social connectedness), cross-lagged regression models identified prospective, bidirectional relationships between perceived impacts of social distancing on one's mental health and both passive and active suicidal ideation. The impact of social distancing on work/social routine was not associated with suicidal ideation. CONCLUSIONS Overall, findings suggest the importance of an individual's perception regarding the effect of social distancing on their mental health, rather than the disruption to work or social routine, in suicide risk. Findings highlight potential targets for suicide risk prevention and intervention.

Abstract
Non-suicidal self-injury (NSSI) co-occurs with both other maladaptive behaviors (e.g., aggression) and emotion dysregulation. However, the extent to which these maladaptive behaviors are linked to NSSI independent of emotion dysregulation is unclear. The present study examined relationships between NSSI and six other maladaptive behaviors among university undergraduates. When controlling for demographic variables, emotion dysregulation, and other maladaptive behaviors, binge eating, purging, illicit drug use, and physical aggression were each related to lifetime NSSI history and/or severity. No maladaptive behaviors were significantly related to the presence of current diagnostic-level NSSI in these multivariate analyses. Results suggest that some maladaptive behaviors may relate uniquely to NSSI risk independent of emotion dysregulation, highlighting the importance of considering such behaviors in self-injury assessment and treatment.

Abstract
Background: Challenges and inconsistencies in defining nonsuicidal self-injury (NSSI) have persisted for decades, which significantly impact NSSI conceptualization and assessment in clinical and research settings and impede the field's progress. Aims: The present study aimed to solicit opinions from individuals with NSSI expertise so as to improve the operational definition and conceptualization of NSSI. Method: We asked researchers, clinicians, and graduate students with varying NSSI expertise to provide opinions on six NSSI definitional components (e.g., whether pain should be a required outcome), as well as to review 118 behaviors and indicate whether each is NSSI. Results: Responses (N = 159) revealed good agreement on specific NSSI definitional aspects and the classification of oft-cited NSSI behaviors. However, findings also demonstrated potential discrepancies in how clinicians and researchers define NSSI when compared with specific behaviors that might be classified as NSSI. Limitations: The opinions of the study's sample may not reflect the wider NSSI field. Conclusion: Findings suggest that there is an increased need for a clear and consistent definition of NSSI and specific NSSI behaviors. There is also a need to develop new assessment measures that capture the range of NSSI behaviors that received good-to-excellent agreement among self-injury experts.

Abstract
Evidence suggests that the negative consequences of COVID-19 may extend far beyond its considerable death toll, having a significant impact on psychological well-being. Despite work highlighting the link between previous epidemics and elevated suicide rates, there is limited research on the relationship between the COVID-19 pandemic and suicidal thoughts and behaviors. Utilizing an online survey, the current study aimed to better understand the presence, and extent, of the association between COVID-19-related experiences and past-month suicidal thoughts and behaviors among adults in the United States recruited via Amazon Mechanical Turk (n = 907). Results support an association between several COVID-19-related experiences (i.e., general distress, fear of physical harm, effects of social distancing policies) and past-month suicidal ideation and suicide attempts. Further, a significant proportion of those with recent suicidal ideation explicitly link their suicidal thoughts to COVID-19. Exploratory analyses highlight a potential additional link between COVID-19 and suicidal behavior, suggesting that a portion of individuals may be intentionally exposing themselves to the virus with intent to kill themselves. These findings underscore the need for suicide risk screening and access to mental health services during the current pandemic. Particular attention should be paid to employing public health campaigns to disseminate information on such services to reduce the enormity of distress and emotional impairment associated with COVID-19 in the United States.

Abstract
OBJECTIVE There is significant debate about the feasibility of using predictive models for suicide prevention. Although statistical considerations have received careful attention, patient perspectives have not been examined. This study collected feedback from high-risk veterans about the U.S. Department of Veterans Affairs (VA) prevention program called Recovery Engagement and Coordination for Health-Veterans Enhanced Treatment (REACH VET). METHODS Anonymous questionnaires were obtained from veterans during their stay at a psychiatric inpatient unit (N=102). The questionnaire included three vignettes (the standard VA script, a more statistical vignette, and a more collaborative vignette) that described a conversation a clinician might initiate to introduce REACH VET. Patients rated each vignette on several factors, selected their favorite vignette, and provided qualitative feedback, including recommendations for clinicians. RESULTS All three vignettes were rated as neutral to very caring by more than 80% of respondents (at least 69% of respondents rated all vignettes as somewhat caring to very caring). Similar positive feedback was obtained for several ratings (e.g., helpful vs. unhelpful, informative vs. uninformative, encouraging vs. discouraging). There were few differences in the ratings of the three vignettes, and each of the three scripts was preferred as the "favorite" by at least 28% of the sample. Few patients endorsed concerns that the discussion would increase their hopelessness, and privacy concerns were rare. Most of the advice for clinicians emphasized the importance of a patient-centered approach. CONCLUSIONS The results provide preliminary support for the acceptability of predictive models to identify patients at risk for suicide, but more stakeholder research is needed.

Abstract
OBJECTIVE Text-based responses may provide significant contributions to suicide risk prediction, yet research including text data is limited. This may be due to a lack of exposure and familiarity with statistical analyses for this data structure. METHOD The current study provides an overview of data processing and statistical algorithms for text data, guided by an empirical example of 947 online participants who completed both open-ended items and traditional self-report measures. We give an introduction to a number of text-based statistical approaches, including dictionary-based methods, topic modeling, word embeddings, and deep learning. RESULTS We analyze responses from the open-ended question "How do you feel today?", detailing characteristics of the responses, as well as predicting past-year suicidal ideation. CONCLUSIONS We see the analysis of text from social media, open-ended questions, and other text sources (i.e., medical records) as an important form of complementary assessment to traditional scales, shedding insight on what we are missing in our current set of questionnaires, which may ultimately serve to improve both our understanding and prediction of suicide.

Abstract
OBJECTIVE As recent advances in suicide research have underscored the importance of studying distinct suicide outcomes (i.e., suicidal thinking vs. behavior), there is a need to consider the theoretical meaningfulness of our statistical approach(es). As an alternative to more popular statistical methods, we introduce ordinal regression, detailing specific forms that are well-aligned to examine outcomes specific to suicide research. METHOD Ordinal regression models allow for assessment of the influences of covariates on the experience of lower (i.e., suicidal ideation) to higher (i.e., suicidal planning) suicide risk outcomes. RESULTS As an empirical application, we fit a sequential ordinal regression model with 17 theoretically selected covariates and modeled category specific effects for each covariate. CONCLUSIONS Results detailed from depression and presence of nonsuicidal self-injury demonstrate the utility of ordinal regression in consideration of transitions across suicide outcomes. Ordinal regression models may be particularly informative in identifying risk factors unique to each suicide outcome, which has the potential to meaningfully inform theoretical models of suicide and suicide risk prediction.

Abstract
Background: Patient disclosure of prior suicidal behaviors is critical for effectively managing suicide risk; however, many attempts go undisclosed. Aims: The current study explored how responses following a suicide attempt disclosure may relate to help-seeking outcomes. Method: Participants included 37 veterans with a previous suicide attempt receiving inpatient psychiatric treatment. Veterans reported on their most and least helpful experiences disclosing their suicide attempt to others. Results: Veterans disclosed their suicide attempt to approximately eight individuals. Mental health professionals were the most cited recipient of their most helpful disclosure; romantic partners were the most common recipient of their least helpful disclosures. Positive reactions within the context of the least helpful disclosure experience were positively associated with a sense of connection with the disclosure recipient. Positive reactions within the most helpful disclosure experience were positively associated with the likelihood of future disclosure. No reactions were associated with having sought professional care or likelihood of seeking professional care. Limitations: The results are considered preliminary due to the small sample size. Conclusion: Findings suggest that while positive reactions may influence suicide attempt disclosure experiences broadly, additional research is needed to clarify factors that drive the decision to disclose a suicide attempt to a professional.

Nonsuicidal self-injury scar concealment from the self and others. J Psychiatr Res 2020; 130:313-320.

Abstract
Despite the high prevalence of nonsuicidal self-injury (NSSI) and resultant physical scarring, few studies have explored the occurrence and psychological implications of concealing NSSI scars. This study examines NSSI scar concealment from the self and others, as well as the cognitive, affective, and self-injury-related correlates of these concealment practices. This study aimed to characterize the extent to which individuals who engage in concealment practices have a history of, or desire to engage in, treatment for NSSI specifically geared towards NSSI scarring. Adults with at least one NSSI scar (N = 278) completed online questionnaires measuring NSSI engagement and scarring, scar concealment behaviors, scar-related cognitions, as well as symptoms of anxiety and depression, and recent suicidal ideation and NSSI urges. Results indicate that the degree of scar concealment from the self and from others is associated with greater experiences of negative scar-related cognitions, higher levels of anxiety and depressive symptomatology, and higher severity of NSSI urges. These correlations persisted after accounting for NSSI severity indices, including extent of NSSI scarring, suggesting that scar concealment practices may be important clinical indicators of current distress and potential future self-injury. Future research should explore the extent to which scar concealment practices are longitudinally associated with distress and risk for NSSI maintenance.

[PMID: 33084062 DOI: 10.1002/jclp.23073] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2020] [Revised: 09/25/2020] [Accepted: 09/29/2020] [Indexed: 11/11/2022]
Abstract
OBJECTIVES Though nonsuicidal self-injury (NSSI) is generally considered to be a private act, 21%-52% of individuals who engage in NSSI do so around others. Those who engage in NSSI alone often demonstrate severe behavior. However, little is known about the distinction between those who only sometimes versus always engage in NSSI when they are around others. Three groups of individuals who engage in NSSI were examined: Always, sometimes, and never alone. METHOD Participants (N = 861; 84.2% female; M age = 20.06) were undergraduates who answered online questionnaires. Severity of NSSI, suicide risk, and social risk factors were used to predict group membership. RESULTS Engaging in NSSI around others aligned with less severe NSSI behavior, lower suicide risk, and fewer interpersonal difficulties versus those who engage in NSSI alone. CONCLUSIONS NSSI's social context may indicate clinical severity. This information is useful for clinicians who work with individuals with a history of NSSI.

Characterizing the choice to disclose nonsuicidal self-injury. J Clin Psychol 2020; 77:683-700. [PMID: 32869874 DOI: 10.1002/jclp.23045] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2020] [Revised: 06/08/2020] [Accepted: 08/03/2020] [Indexed: 11/09/2022]
Abstract
OBJECTIVE Despite nonsuicidal self-injury (NSSI) being a prevalent and problematic behavior, only approximately half of those who engage in NSSI disclose their behavior. Yet, limited research has explored the choice to disclose. This study sought to identify if NSSI characteristics, emotional distress, and perceived interpersonal obstacles discriminated between NSSI disclosure status. Exploratory aims also investigated reasons for one's disclosure decision and disclosure contextual factors. METHOD Participants included 977 undergraduate students (83% female) with a lifetime history of NSSI. RESULTS Greater NSSI intrapersonal functions, suicide risk, and significant other support, and lower depression symptoms were associated with NSSI disclosure. Exploratory results highlight perceptions of one's NSSI severity and desire to receive support in disclosure choice; intrapersonal functions and peer support were associated with the timing of disclosure. CONCLUSIONS Findings underscore the potential importance of individual attitudes toward NSSI, in addition to traditionally measured risk factors, as potential drivers in NSSI disclosure.

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.

An investigation of clinical decisionmaking: identifying important factors in treatment planning for suicidal patients in the emergency department. J Am Coll Emerg Physicians Open 2020; 1:383-391. [PMID: 33000061 PMCID: PMC7493507 DOI: 10.1002/emp2.12087] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Revised: 04/09/2020] [Accepted: 04/13/2020] [Indexed: 11/28/2022] Open
Abstract
OBJECTIVE We sought to evaluate the influence of several well-documented, readily available risk factors that may influence a psychiatric consultant's decision to admit an emergency department (ED) patient reporting suicidal ideation for psychiatric hospitalization. METHODS We conducted a retrospective study of adult patients presenting to six affiliated EDs within Pennsylvania from January 2015 to June 2017. We identified 533 patients reporting current active suicidal ideation and receiving a complete psychiatric consultation. Socio-demographic characteristics, psychiatric presentation and history, and disposition were collected. Decision tree analysis was conducted with disposition as the outcome. RESULTS Four of 27 variables emerged as most influential to decisionmaking, including psychiatric consultant determination of current suicide risk, patient age, current depressive disorder diagnosis, and patient history of physical violence. Likelihood of admission versus discharge ranged from 97% to 58%, depending on the variables considered. Post hoc analysis indicated that current suicide plan, access to means, lack of social support, and suicide attempt history were significantly associated with psychiatric consultant determination of moderate-to-high suicide risk, with small-to-medium effect sizes emerging. CONCLUSIONS Only a handful of variables drive disposition decisions for ED patients reporting current active suicidal ideation, with both high and low fidelity decisions made. Patient suicide risk, determined by considering empirically supported risk factors for suicide attempt and death, contributes the greatest influence on a psychiatric consultant's decision to admit. In line with American College of Emergency Physicians (ACEP) recommendations, this study accentuates the importance of using clinical judgment and adjunct measures to determine patient disposition within this population.

Abstract
The Caring Contacts suicide prevention intervention has been promoted by the Joint Commission, given its effectiveness, high reach, and cost effectiveness. Despite its increased application, no study has examined whether patient characteristics influence perceptions of the intervention, which may inform implementation efforts and ultimately impact effectiveness. One hundred fifty-four veterans were recruited from a Veterans Affairs psychiatric inpatient unit. Participants completed a survey to provide feedback on preferences, including the message correspondent, format (e.g., postcard, email), the importance of handwriting (vs. typed), visual presentation, and schedule for mailings. Results demonstrated that Caring Contacts preferences did not differ by most variables, including military rank, combat deployment history, or most personal technology use characteristics. Some demographic differences were identified, especially by age. More older veterans preferred messages to be sent in a physical letter compared to younger veterans, but if messages were sent via postal mail, younger veterans had a stronger preference for messages to be handwritten and sent using real stamps and colorful envelopes. Overall, findings suggest that few Caring Contacts adaptations are needed based on patient characteristics. Programs targeting older cohorts should consider postal mail formats for Caring Contacts.

Abstract
IMPORTANCE Both nonsuicidal self-injury (NSSI), defined as the direct, deliberate damage of one's body tissue without suicidal intent, and internet addiction among adolescents are public health concerns. However, the possible association of NSSI with internet addiction is not well understood. OBJECTIVE To examine the occurrence of internet addiction with NSSI and any sex differences among Chinese adolescents. DESIGN, SETTING, AND PARTICIPANTS A multicenter, cross-sectional, survey study was conducted from February 18 to October 15, 2015, among adolescents aged 11 to 20 years from 343 classes in 45 public high schools across 5 provinces of China. Data analysis was performed from August 1, 2018, to March 1, 2019. EXPOSURES Possible internet addiction and internet addiction. MAIN OUTCOMES AND MEASURES Less-frequent (1-4 times) NSSI and more-frequent (≥5 times) NSSI were surveyed using the Chinese version of the Functional Assessment of Self-Mutilation. RESULTS A total of 15 623 students (8043 male [51.5%] and 7580 female [48.5%]) aged 11 to 20 years (mean [SD] age, 15.1 [1.8] years) participated. Of these, 4670 participants (29.9%) met the criteria for possible internet addiction and 509 participants (3.3%) met the criteria for internet addiction. A total of 2667 students (17.1%) engaged in less-frequent NSSI, while 1798 students (11.5%) engaged in more-frequent NSSI in the 12 months preceding the survey. Both possible internet addiction and internet addiction were associated with less-frequent or more-frequent NSSI. The adjusted odds ratios were 1.29 (95% CI, 1.17-1.42) for possible internet addiction and 1.41 (95% CI, 1.11-1.80) for internet addiction for less-frequent NSSI; for more-frequent NSSI, the adjusted odds ratios were 1.75 (95% CI, 1.56-1.96) for possible internet addiction and 2.66 (95% CI, 2.10-3.38) for internet addiction. These associations were similarly observed among age groups of 11 to 14, 15 to 17, and 18 to 20 years. No sex disparities were found in the associations of internet addiction with NSSI, except among adolescents aged 11 to 14 years, where the odds ratios for possible internet addiction with less-frequent NSSI were higher in male adolescents (1.53; 95% CI, 1.25-1.88) than female adolescents (1.13; 95% CI, 0.90-1.47). CONCLUSION AND RELEVANCE Internet addiction appears to be associated with NSSI, and the findings of this study suggest that the association was similar between male adolescents and female adolescents. These data suggest that evaluation of the risk of NSSI for adolescents in association with internet addiction may help health care professionals in developing preventive interventions for NSSI.

Evaluation of Prevention Efforts and Risk Factors Among Veteran Suicide Decedents Who Died by Firearm. Suicide Life Threat Behav 2020; 50:679-687. [PMID: 32017233 DOI: 10.1111/sltb.12618] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2019] [Accepted: 11/08/2019] [Indexed: 11/30/2022]
Abstract
OBJECTIVE Veterans die by suicide at a higher rate than the U.S. population, and veterans more frequently use a firearm as the suicide method. Consequently, firearm accessibility and storage represent important prevention considerations. This project aimed to explore the implementation of suicide prevention efforts among veterans who went on to die by suicide, with and without the use of a firearm, and to identify factors that differentiated veteran suicide decedents to help inform suicide prevention efforts. METHODS Data from the Veteran Health Administration Behavior Health Autopsy Program was analyzed for 97 veteran suicide decedents. RESULTS Results demonstrated that veterans who used a firearm for suicide were less likely to have engaged in suicide prevention efforts overall and were less likely to have received lethal means safety counseling / safety planning. Veterans who died by firearm had lower levels of notable risk factors (e.g., prior suicide attempt, no-shows for appointments), however were more likely to have a documented unsecured firearm in their home. CONCLUSION These findings support the benefit of broadening the reach of suicide prevention efforts, especially for high-risk veterans with access to firearms.

Abstract
Background: Concerns exist regarding the perceived risks of conducting suicide-focused research among an acutely distressed population. Aims: The current study assessed changes in participant distress before and after participation in a suicide-focused research study conducted on a psychiatric inpatient unit. Method: Participants included 37 veterans who were receiving treatment on a psychiatric inpatient unit and completed a survey-based research study focused on suicide-related behaviors and experiences. Results: Participants reported no significant changes in self-reported distress. The majority of participants reported unchanged or decreased distress. Reviews of electronic medical records revealed no behavioral dysregulation and minimal use of as-needed medications or changes in mood following participation. Limitations: The study's small sample size and veteran population may limit generalizability. Conclusion: Findings add to research conducted across a variety of settings (i.e., outpatient, online, laboratory), indicating that participating in suicide-focused research is not significantly associated with increased distress or suicide risk.

Abstract
Only approximately half of individuals engaging in nonsuicidal self-injury (NSSI) ever disclose their behavior. Yet there is a dearth of research aimed at understanding NSSI disclosure and the outcomes of choosing to disclose, such as social reactions to NSSI disclosure. The current study aimed to develop and validate a measure of perceived social reactions to the disclosure of NSSI, the Self-Injury Social Reactions Questionnaire (SI-SRQ). Results supported a three-factor structure of the SI-SRQ assessing positive (tangible aid, emotional support) and negative social reactions in undergraduate ( n = 269), community ( n = 217), and recent NSSI ( n = 129) samples. The internal consistencies of the resultant subscales, in addition to the convergent validity, were also supported. The development of the SI-SRQ provides an avenue to enhance our knowledge of the relationship between social reactions to NSSI disclosure and disclosure outcomes, which may help inform educational efforts about responding to NSSI disclosures more effectively.

Abstract
Despite increased use of behavioral analogues to identify casual mechanisms of self-injurious behavior (e.g., suicide attempts; non-suicidal self-injury), little is known about the impact on participants. The current study examined the impact of a specific behavior analogue, Self-Aggressive Paradigm (SAP), on participant affect. Community participants (n = 507) reported several affective ratings before and after completing SAP task procedures. Following the SAP, participants reported reductions in nervousness and fear and increases in calmness and anger (d = .21). Participants with a current anxiety disorder reported greater increases in happiness; those with a suicide attempt history reported greater increases in sadness. Findings demonstrate the SAP has no adverse mood effects, supporting its use in experimental research.

Abstract
OBJECTIVE The Caring Contacts intervention has been implemented with a variety of methodologies. The purpose of this study was to examine high-risk inpatient preferences for the Caring Contacts intervention. METHOD Veteran psychiatric inpatients (N = 154) completed an anonymous patient preferences survey to obtain feedback on Caring Contact methods such as message wording, preferred correspondent, frequency of contact, duration of the intervention, imagery, and mailing modality. RESULTS Eighty-five percent of veterans Agreed or Strongly Agreed that they would like to receive Caring Contacts from at least one of the correspondent options, with inpatient or outpatient mental health counselor, or primary care physician most preferred. Example messages based on prior studies were overwhelmingly rated as caring and helpful; 84% believed that Caring Contacts could help suicidal individuals. Letters or postcards sent through postal mail were preferred over e-mail or text messages. Participants most commonly thought Caring Contacts should be sent monthly for a period of a year. CONCLUSIONS The results of this study suggest that most high-risk veterans would perceive Caring Contacts as helpful and caring. The results provide several practical, helpful tips for programs seeking to establish a Caring Contacts program.

Abstract
Background: Despite being a major public health concern, it is unclear how suicidal thoughts and behaviors differentially impact separate racial groups. Aims: The aim of the current study was to examine the occurrence of nonlethal suicide events, in addition to suicide attempt characteristics and factors contributing to suicide attempts. Method: A final sample of 7,094 undergraduates from a large northeastern university, identifying as members of three racial groups (White [67.30%], Black [17.30%], and Asian [15.40%]), completed online questionnaires. Results: White participants reported increased likelihood of endorsing lifetime suicidal ideation and plan, whereas Black participants reported decreased likelihood of these events; no differences were found in rates of lifetime suicide attempts. Black participants' suicidal behavior may involve greater ambivalence of intent. A higher proportion of Asian participants endorsed interpersonal factors as contributing to their suicide attempts, whereas a greater percentage of White participants reported internal contributing factors. Limitations: Findings are limited by the sample size and assessment of lifetime suicidal thoughts and behaviors. Conclusion: The findings present a more nuanced look at attitudes and actions related to suicidal thoughts and behaviors that may inform future research and risk assessment procedures.

Predicting status along the continuum of suicidal thoughts and behavior among those with a history of nonsuicidal self-injury. Psychiatry Res 2019; 273:514-522. [PMID: 30708203 DOI: 10.1016/j.psychres.2019.01.067] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Revised: 01/23/2019] [Accepted: 01/23/2019] [Indexed: 12/01/2022]
Abstract
Nonsuicidal self-injury (NSSI) and suicidal thoughts and behavior often co-occur, representing a growing public health concern. Despite extensive research examining suicidal thoughts and behavior among those who engage in NSSI, there is a lack of research investigating factors that, when considered together, can differentiate individuals along the continuum of suicidal thoughts and behavior (no history, suicidal ideation, suicide plan, suicide attempt). This study sought to address this question using a sample of 1178 college students with NSSI history (68.70% female). Discriminant function analysis was conducted including the following predictors: NSSI characteristics, negative affect difficulties, and behavioral and demographic risk factors for suicidal thoughts and behavior. Results suggest that self-disclosure of suicidal ideation, number of lifetime NSSI methods, NSSI frequency, depressive symptoms, and age most parsimoniously differentiate study groups. Those who use a greater number of NSSI methods and acts, paired with higher depressive symptoms and repeated self-disclosure of suicidal ideation are most likely to have a suicide attempt history; decreases in these variables suggest membership within less severe groups. Furthermore, older age may be related to greater suicidality. Findings suggest that the evaluation and co-occurrence of these variables may contribute to a more accurate suicide risk assessment.

The use of machine learning in the study of suicidal and non-suicidal self-injurious thoughts and behaviors: A systematic review. J Affect Disord 2019; 245:869-884. [PMID: 30699872 DOI: 10.1016/j.jad.2018.11.073] [Citation(s) in RCA: 84] [Impact Index Per Article: 16.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2018] [Revised: 10/20/2018] [Accepted: 11/11/2018] [Indexed: 12/23/2022]
Abstract
BACKGROUND Machine learning techniques offer promise to improve suicide risk prediction. In the current systematic review, we aimed to review the existing literature on the application of machine learning techniques to predict self-injurious thoughts and behaviors (SITBs). METHOD We systematically searched PsycINFO, PsycARTICLES, ERIC, CINAHL, and MEDLINE for articles published through February 2018. RESULTS Thirty-five articles met criteria to be included in the review. Included articles were reviewed by outcome: suicide death, suicide attempt, suicide plan, suicidal ideation, suicide risk, and non-suicidal self-injury. We observed three general aims in the use of SITB-focused machine learning analyses: (1) improving prediction accuracy, (2) identifying important model indicators (i.e., variable selection) and indicator interactions, and (3) modeling underlying subgroups. For studies with the aim of boosting predictive accuracy, we observed greater prediction accuracy of SITBs than in previous studies using traditional statistical methods. Studies using machine learning for variable selection purposes have both replicated findings of well-known SITB risk factors and identified novel variables that may augment model performance. Finally, some of these studies have allowed for subgroup identification, which in turn has helped to inform clinical cutoffs. LIMITATIONS Limitations of the current review include relatively low paper sample size, inconsistent reporting procedures resulting in an inability to compare model accuracy across studies, and lack of model validation on external samples. CONCLUSIONS We concluded that leveraging machine learning techniques to further predictive accuracy and identify novel indicators will aid in the prediction and prevention of suicide.
