The effect of parent-adolescent discrepancies in reports of familial dysfunction and depression on suicidal ideation in adolescents.

INTRODUCTION: Parents and adolescents are often discrepant in their reports of adolescent psychosocial factors. Few studies have addressed parent-adolescent discrepancies in subjective ratings of familial dysfunction and depression as longitudinal predictor variables, and none have done so in a treatment setting for adolescents with acute suicidality. This study examined how parent-adolescent discrepancies in familial dysfunction and depression impact adolescent treatment response in an intensive outpatient program for suicidality. METHODS: Adolescents (N = 315) were assessed at treatment entry and exit for familial dysfunction, depression, and suicidal ideation. Parents received parallel assessments of familial dysfunction and adolescent depression at each time point. A polynomial regression was conducted to determine whether parent-adolescent discrepancies in reports of familial dysfunction and depression at entry related to the treatment outcome of adolescent-reported depression and suicide ideation at exit. RESULTS: Significant discrepancies were present with on average adolescents reporting more depression and familial dysfunction than parents. Entry discrepancy in familial dysfunction (but not depression) predicted suicide ideation at exit. CONCLUSIONS: Our results suggest that parent-adolescent discrepancies in perception of familial dysfunction is a risk factor for poor outcomes in suicidal youth and might be a fruitful target in treatment programs.

Suicide risk assessment and suicide risk management protocol for the Texas Youth Depression and Suicide Research Network.

Introduction: Suicide prevention research is a national priority, and national guidance includes the development of suicide risk management protocols (SRMPs) for the assessment and management of suicidal ideation and behavior in research trials. Few published studies describe how researchers develop and implement SRMPs or articulate what constitutes an acceptable and effective SRMP. Methods: The Texas Youth Depression and Suicide Research Network (TX-YDSRN) was developed with the goal of evaluating screening and measurement-based care in Texas youth with depression or suicidality (i.e., suicidal ideation and/or suicidal behavior). The SRMP was developed for TX-YDSRN through a collaborative, iterative process, consistent with a Learning Healthcare System model. Results: The final SMRP included training, educational resources for research staff, educational resources for research participants, risk assessment and management strategies, and clinical and research oversight. Conclusion: The TX-YDSRN SRMP is one methodology for addressing youth participant suicide risk. The development and testing of standard methodologies with a focus on participant safety is an important next step to further the field of suicide prevention research.

The Quick Inventory of Depressive Symptomatology, Adolescent Version (QIDS-A17): A Psychometric Evaluation.

Objective: The current study aimed to evaluate the psychometric features of the Quick Inventory of Depressive Symptomatology, Adolescent version (QIDS-A17) and the clinician-rated Children's Depression Rating Scale-Revised (CDRS-R). Methods: Altogether, 103 outpatients (8 to 17 years) completed the self-report QIDS-A17-SR. Clinician interviews of adolescents (QIDS-A17-C (Adolescent)) and of parents (QIDS-A17-C (Parent)) were combined to create the QIDS-A17-C(Composite) and the CDRS-R. Results: All QIDS-A17 measures and the CDRS-R evidenced high total score correlations and internal consistency. Factor analysis found all four measures to be unidimensional. Item Response Theory (IRT) analysis found results that complemented the reliability results found in CTT. All four also demonstrated discriminant diagnostic validity based on logistic regression and ANOVA analyses. Conclusion: The psychometric properties of the self-report and composite versions of the QIDS-A17 suggest acceptability as a measure of depression in adolescents either as a measure of depressive symptoms or severity of illness in adolescents. The self-report version may be a helpful tool in busy clinical practices.

Predicting Remission From Depression in Youth Receiving Outpatient Medication Management.

Objective: To examine 6-month remission rates of adolescents treated for depression in a university-based clinic and examine predictors of eventual remission.Methods: All patients aged 11-18 years treated in the clinic completed self-report measures assessing depression, suicidal ideation, anxiety, and associated symptoms. Remission was operationalized as a total score of ≤ 4 on the Patient Health Questionnaire-9 (PHQ-9) within 6 months of entering treatment.Results: Of the 430 patients, (76.74% female, 65.34% Caucasian, mean ± SD age 14.65 ± 1.69 years), 26.74% achieved remission within 6 months. Mean ± SD scores on the PHQ-9 at visit 1 (clinic entry) were 11.97 ± 4.76 for remitters (n = 115) and 15.03 ± 5.21 for non-remitters (n = 315). Predicted odds of remitting decreased as depressive symptom severity at visit 1 increased (OR = 0.941; 95% CI, 0.886 to 1.000; P = .051) and as scores on the Concise Associated Symptoms Tracking scale at treatment entry increased (OR = 0.971; 95% CI, 0.948 to 0.995; P = .017). As depression severity increased between visits, odds of remitting decreased (OR = 0.873; 95% CI, 0.827 to 0.921; P < .0001). Finally, adolescent males were more likely to achieve remission than females within 6 months (OR = 2.257; 95% CI, 1.351 to 3.771; P = .002).Conclusions: This study reports remission rates for depressed youth receiving medication management in a naturalistic outpatient setting. Results confirm that depression severity at treatment initiation and over time is a strong predictor of remission status. Additionally, monitoring associated symptoms via measurement-based care can provide important clinical information to inform treatment decisions.

Forty-Eight Week Outcomes of a Site-Randomized Trial of Combined Cognitive Behavioral Therapy and Medication Management Algorithm for Treatment of Depression Among Youth With HIV in the United States.

BACKGROUND: Studies suggest that manualized, measurement-guided, depression treatment is more efficacious than usual care but impact can wane. Our study among youth with HIV (YWH), aged 12-24 years at US clinical research sites in the International Maternal Pediatric Adolescent AIDS Clinical Trials Network, found a significant reduction in depressive symptoms among YWH who received a manualized, measurement-guided treatment. This paper reports outcomes up to 24 weeks after the intervention. METHODS: Eligibility included diagnosis of ongoing nonpsychotic depression. Using restricted randomization, sites were assigned to either combination cognitive behavioral therapy and medication management algorithm tailored for YWH or to enhanced standard of care, which provided psychotherapy and medication management. Site-level mean Quick Inventory for Depression Symptomatology Self-Report (QIDS-SR) scores and proportion of youth with treatment response (>50% decrease from baseline) and remission (QIDS-SR ≤ 5) were compared across arms using t tests. RESULTS: Thirteen sites enrolled 156 YWH, with baseline demographic factors, depression severity, and HIV disease status comparable across arms. At week 36, the site-level mean proportions of youth with a treatment response and remission were greater at combination cognitive behavioral therapy and medication management algorithm sites (52.0% vs. 18.8%, P = 0.02; 37.9% vs. 19.4%, P = 0.05), and the mean QIDS-SR was lower (7.45 vs. 9.75, P = 0.05). At week 48, the site-level mean proportion with a treatment response remained significantly greater (58.7% vs. 33.4%, P = 0.047). CONCLUSIONS: The impact of manualized, measurement-guided cognitive behavioral therapy and medication management algorithm tailored for YWH that was efficacious at week 24 continued to be evident at weeks 36 and 48.

A Characterization of the Clinical Global Impression Scale Thresholds in the Treatment of Adolescent Depression Across Multiple Rating Scales.

Introduction: The Clinical Global Impressions-Improvement (CGI-I) scale is widely used in clinical research to assess symptoms and functioning in the context of treatment. The correlates of the CGI-I with efficacy scales for adolescent major depressive disorder are poorly understood. This study focused on benchmarking CGI-I scores with changes in the Children's Depression Rating Scale-Revised (CDRS-R) and the Quick Inventory of Depressive Symptomatology-Adolescent (17-item) Self-Report (QIDS-A17-SR). Methods: We examined three datasets with the clinician-rated CDRS-R to ascertain equivalent percent changes in total scores and CGI-I ratings. Exploratory analyses examined corresponding percentage changes in the QIDS-A17-SR and the CGI-I ratings. The CGI-I was the reference scale for nonparametric equipercentile linking with the Equate package in R. Results: CGI-I scores of 1 mapped to ≥78%-95% change in CDRS-R scores at 4-6 weeks across three datasets. CGI-I scores of 2 mapped to 56%-94% change in CDRS-R scores at 4-6 weeks across three studies. CGI-I scores of 3 mapped to 30%-68% changes in CDRS-R scores at 4-6 weeks across three studies. CGI-I scores of 4 mapped to a range of 29%-44% at 4-6 weeks across three studies. There was no significant difference (p ≥ 0.6) between treatment groups in both the Treatment of Adolescents with Depression and Treatment of Resistant Depression in Adolescents studies, for each CGI-I score ( = 1, or = 2 or = 3, or ≥4), associated mapping of total depression severity score, or associated percent change from baseline for corresponding follow-up visits. There was no significant sex difference (p > 0.2) in CGI-I linkages to CDRS-R total or percentage changes. Conclusions: These findings establish clear relationships among CGI-I scores and the CDRS-R and the QIDS-A17-SR. These benchmarks have utility for clinical trial study design, inter-rater reliability training, and clinical implementation.

Borderline personality features influence treatment response to suicide prevention.

BACKGROUND: Suicide is a notable risk for individuals with features of borderline personality disorder. Given the centrality of interpersonal difficulties in this disorder, we proposed that the negative interpersonal cognitions (perceived burdensomeness and thwarted belongingness) identified by the Interpersonal Theory of Suicide (IPTS) may explain the associations between suicidal ideation and borderline personality features. METHOD: Participants were 322 suicidal youth (74% girls) aged 11-18 years (M, SD = 14.74, 1.6) in an intensive outpatient program in the southwest United States. Youth completed measures assessing borderline personality features at program entry, and suicidal ideation and IPTS variables at entry and exit. RESULTS: Borderline personality features did not moderate associations of IPTS variables and suicidal ideation. For the entire sample, changes in suicidal ideation from entry to discharge occurred in tandem with changes in perceived burdensomeness and depressive symptoms, but not thwarted belongingness. Youth with elevated borderline personality features entered with greater suicidal ideation, but improved more from treatment entry to exit. Regardless of level of borderline personality features, changes in negative interpersonal cognitions over treatment were associated with changes in suicidal ideation. LIMITATIONS: Self-report measures and lack of sample diversity are study limitations. CONCLUSIONS: This research highlights the clinical utility of the IPTS variables and the importance of promoting competence and interpersonal connectedness when treating this population. Findings indicate that the IPTS variables carry the same fundamental information for contributing to suicidal ideation, regardless of level of borderline personality features.

Evidence for machine learning guided early prediction of acute outcomes in the treatment of depressed children and adolescents with antidepressants.

BACKGROUND: The treatment of depression in children and adolescents is a substantial public health challenge. This study examined artificial intelligence tools for the prediction of early outcomes in depressed children and adolescents treated with fluoxetine, duloxetine, or placebo. METHODS: The study samples included training datasets (N = 271) from patients with major depressive disorder (MDD) treated with fluoxetine and testing datasets from patients with MDD treated with duloxetine (N = 255) or placebo (N = 265). Treatment trajectories were generated using probabilistic graphical models (PGMs). Unsupervised machine learning identified specific depressive symptom profiles and related thresholds of improvement during acute treatment. RESULTS: Variation in six depressive symptoms (difficulty having fun, social withdrawal, excessive fatigue, irritability, low self-esteem, and depressed feelings) assessed with the Children's Depression Rating Scale-Revised at 4-6 weeks predicted treatment outcomes with fluoxetine at 10-12 weeks with an average accuracy of 73% in the training dataset. The same six symptoms predicted 10-12 week outcomes at 4-6 weeks in (a) duloxetine testing datasets with an average accuracy of 76% and (b) placebo-treated patients with accuracies of 67%. In placebo-treated patients, the accuracies of predicting response and remission were similar to antidepressants. Accuracies for predicting nonresponse to placebo treatment were significantly lower than antidepressants. CONCLUSIONS: PGMs provided clinically meaningful predictions in samples of depressed children and adolescents treated with fluoxetine or duloxetine. Future work should augment PGMs with biological data for refined predictions to guide the selection of pharmacological and psychotherapeutic treatment in children and adolescents with depression.

Fearlessness about death and suicide planning predict lethality of adolescent suicide attempts during and following treatment.

INTRODUCTION: The rate of adolescent suicide attempt has increased drastically over the past 10 years. However, little is known regarding what predicts a more versus less lethal attempt, which is of critical interest to clinicians managing this at-risk population. We sought to extend the study of lethality in adolescents by exploring its relationship with two recognized risk-factors for suicide attempt: fearlessness about death (FAD) and suicide planning. METHODS: Participants (N = 254) were administered measures of FAD and depressive symptoms upon entering intensive outpatient treatment for adolescents exhibiting suicidal thoughts and behaviors. Attempts made between treatment entry and 6 months following discharge (n = 47) were scored on a 4-point ordinal scale of lethality. The resulting continuum ranged from no attempt to attempts of low to moderate levels of lethality. RESULTS: FAD and suicide planning distinguished between levels of lethality of future attempt at the bivariate and multivariate level. FAD's predictive relationship with lethality while controlling for age, sex, depression, and prior attempt diminished when suicide planning was covaried. CONCLUSION: FAD and suicide planning significantly predicted more versus less lethal future attempts in our sample of adolescents in a clinical setting. Our findings suggest that FAD influences the lethality of a future attempt by promoting planning for suicide. More studies are needed to assess whether the brief FAD scale might be a valuable adjunct in the clinical management of youth with suicidal thoughts and behaviors.

Site-Randomized Controlled Trial of a Combined Cognitive Behavioral Therapy and a Medication Management Algorithm for Treatment of Depression Among Youth Living With HIV in the United States.

BACKGROUND: Depression is frequent among youth living with HIV (YLWH). Studies suggest that manualized treatment guided by symptom measurement is more efficacious than usual care. SETTING: This study evaluated manualized, measurement-guided depression treatment among YLWH, aged 12-24 years at 13 US sites of the International Maternal Pediatric Adolescent AIDS Clinical Trials Network. METHODS: Using restricted randomization, sites were assigned to either a 24-week, combination cognitive behavioral therapy and medication management algorithm (COMB-R) tailored for YLWH or to enhanced standard of care, which provided standard psychotherapy and medication management. Eligibility included diagnosis of nonpsychotic depression and current depressive symptoms. Arm comparisons used t tests on site-level means. RESULTS: Thirteen sites enrolled 156 YLWH, with a median of 13 participants per site (range 2-16). At baseline, there were no significant differences between arms on demographic factors, severity of depression, or HIV status. The average site-level participant characteristics were as follows: mean age of 21 years, 45% male, 61% Black, and 53% acquired HIV through perinatal transmission. At week 24, youth at COMB-R sites, compared with enhanced standard of care sites, reported significantly fewer depressive symptoms on the Quick Inventory for Depression Symptomatology Self-Report (QIDS-SR score 6.7 vs. 10.6, P = 0.01) and a greater proportion in remission (QIDS-SR score ≤ 5; 47.9% vs. 17.0%, P = 0.01). The site mean HIV viral load and CD4 T-cell level were not significantly different between arms at week 24. CONCLUSIONS: A manualized, measurement-guided psychotherapy and medication management algorithm tailored for YLWH significantly reduced depressive symptoms compared with standard care at HIV clinics.

Validation of Fearlessness about Death Scale in adolescents.

Recent theories of suicide behavior have proposed a risk factor that differentiates suicide ideators from suicide attempters: Suicide capability. Fearlessness about death, one component of capability, has predicted the likelihood of a future attempt in adult samples. Although there is preliminary evidence about its value in youth, the fearlessness about death scale (FAD) has not yet been validated in clinical adolescents. We sought to examine the psychometric properties of this scale in adolescents at high risk for making a future suicide attempt. Youth who were evaluated for an intensive outpatient program (IOP) for suicidal adolescents (N = 496; M, SD for age = 14.78, 1.59) reported lifetime history of suicide attempts and NSSI, suicide ideation, depressive symptoms, and completed the FAD at entry and at discharge (n = 329). Confirmatory factor analysis showed structural validity of the FAD scale and its invariance across age, sex, and time. Independent t-tests indicated that FAD scores distinguished between those with and without NSSI, as well as those with single versus multiple attempts. When depression was covaried in logistic regression analyses, FAD's relationship with suicide attempt history persisted, showing the construct's divergence from depression. Our findings present psychometric validity in adolescents for a widely used scale developed for adults. This validation offers confidence that this promising risk factor can be adequately investigated in adolescents. If future studies can confirm its predictive validity, the brevity of this scale would make it a practical addition to a clinical assessment.

Implementing the interpersonal theory of suicide to improve outcomes in suicidal adolescents: A pilot trial.

INTRODUCTION: The Interpersonal Psychological Theory of Suicide proposes two constructs that serve as a final common pathway to suicidal ideation: thwarted belongingness and perceived burdensomeness. There have been few translations of this theory to clinical care. This study aimed to address this limitation by targeting burden cognitions with novel interventions. METHODS: A pilot clinical trial was conducted in an evidence-based intensive outpatient program for suicidal youth. Participants were 123 adolescents who completed measures at intake, discharge, and one-month follow-up. The experimental group consisted of standard care plus study interventions, which was compared with an active control group of standard care. Feedback on intervention acceptability was gathered through qualitative interviews with parents and adolescents. RESULTS: There was a statistically significant drop in thwarted belongingness at discharge and an improvement in perceived burdensomeness at discharge (not statistically significant, small effect size). Feedback on acceptability was favorable and supported implementation. CONCLUSION: This study adds to the literature by being the first to utilize the construct of perceived burdensomeness in clinical interventions for suicidal youth; illustrating one potential avenue for translating theory to practice. The unexpected effects on thwarted belongingness have implications for the role of these constructs in a treatment setting.

Refinement of the Role of Hopelessness in the Interpersonal Theory of Suicide: An Exploration in an Inpatient Adolescent Sample.

Hopelessness is a well-established risk factor for suicidal ideation. Recent research has indicated that hopelessness can be split into two subsets: pessimism (PESS) and lack of optimism (LOO) and that LOO is more salient of the two in predicting suicide ideation (SI). The aim of this study was to examine the relationship of PESS and LOO to SI in the context of the Interpersonal Psychological Theory of Suicide (IPTS). Participants were 294 inpatient adolescents. LOO but not PESS was associated with SI. LOO interacted with the IPTS variable of perceived burdensomeness to differentiate between passive and active SI, partly consistent with the theory. These results support the value of separating the two components of hopelessness in understanding adolescent SI.

Fearlessness about death predicts adolescent suicide attempt: A preliminary analysis.

OBJECTIVE: Several theories of suicide suggest that people will only attempt suicide if they have both the desire to die and the capability for suicide. Fearlessness about death is a key component of capability for suicide. There is little information in the literature about the prospective relationship between fearlessness about death and suicide attempt in adolescents. METHOD: We obtained baseline fearlessness about death from adolescents (N = 122; ages 12-18; 80% girls; 82% Caucasian) who received intensive outpatient treatment for active suicidal ideation and/or a recent attempt. We tested if fearlessness about death at treatment entry predicted an attempt (n = 14) between entry and six-month follow-up after discharge from the program. RESULTS: Fearlessness about death significantly predicted the presence of an attempt between treatment entry and six-month follow-up after controlling for common covariates (Quade F = 2.15, p < .02). CONCLUSIONS: In a preliminary analysis of a group of suicidal adolescents, fearlessness about death was a significant independent predictor of attempt between treatment entry and six months post-discharge, even when controlling for other commonly cited risk factors.

Predicting future suicidal events in adolescents using the Concise Health Risk Tracking Self-Report (CHRT-SR).

BACKGROUND: Several self-report rating scales have been developed to assess suicidal ideation, yet most have limited utility in predicting future suicide attempts. This is particularly critical in adolescence, where suicide is the second leading cause of death. This study evaluated the Concise Health Risk Tracking Self-Report (CHRT-SR) as a prospective predictor of suicide attempts and events in high-risk adolescents enrolled in a suicide-prevention intensive outpatient program (IOP). METHODS: Data were collected by retrospective chart review of adolescents treated in IOP for youth with severe suicidality. At baseline, youth completed the 14-item CHRT-SR (CHRT-SR14), which assesses suicide risk based on 3 subscales: Propensity, Impulsivity, and Suicidal Thoughts. Two outcomes were assessed: actual suicide attempts and suicidal events (suicide attempt, inpatient hospitalization, or emergency department visit) during the IOP. RESULTS: Of the 251 adolescents who completed the baseline CHRT-SR14, 26 had a suicidal event during IOP (mean time in IOP: 5.4 ± 2.3 weeks), of whom 14 had an actual suicide attempt. Youth with any suicidal event had higher scores than those without an event on the CHRT-SR14 Total (p = .005), Propensity (p = .008), and Suicidal Thoughts (p = .001) scales at baseline. Youth who made a suicide attempt had significantly higher scores than those without an event for the Total Score, Propensity, and Suicidal Thoughts subscales. CHRT-SR14 Total Score of 28 had a sensitivity of 85.7% and specificity of 56.5% in predicting suicide attempts. A score of 22 predicted suicidal events, with a sensitivity of 80.8% and specificity of 40.9%. CHRT-SR7 Total Score of 12 predicted suicide attempts, with a sensitivity of 85.7% and specificity of 53.4%. CONCLUSIONS: The CHRT-SR14 self-report predicts suicide attempts and events with at least 80% sensitivity and acceptable specificity in adolescents at high-risk for suicide.

The association between baseline insomnia symptoms and future suicide attempts within an intensive outpatient treatment program for suicide.

This study examines the prospective relationship between insomnia symptoms and suicide attempts in high-risk youth. We obtained depressive symptoms, insomnia symptoms, and suicide ideation measures from clinical records of 206 adolescents ages 12-17 at entry and discharge from a suicide prevention intensive outpatient program. Information about whether the participant made a suicide attempt was available through six months after discharge. Patients were mainly girls (79.1%; n = 163) with depression (89.8%; n = 185). Associations between insomnia symptoms, attempts within 6 months of discharge, persistent insomnia symptoms, and suicide ideation at discharge were tested with multiple regression analyses. Entry insomnia symptoms were prospectively associated with attempts when controlling for age, sex, and previous attempts, but insomnia symptoms at discharge were not. Suicide ideation at discharge was associated both with entry insomnia symptoms and attempts within 6 months of discharge. When entry and discharge suicide ideation were controlled, the association between entry insomnia symptoms and attempts lost significance. However, the association between discharge ideation and attempts remained significant. Insomnia symptoms contribute indirectly to suicide attempt risk after discharge. Intensive treatment for ideation and reducing insomnia symptoms could reduce discharge suicide risk and subsequent suicide attempts.

Dysfunctional adaptive immune response in adolescents and young adults with suicide behavior.

BACKGROUND: Immune system dysfunction has been implicated in the pathophysiology of suicide behavior. Here, we conducted an exploratory analysis of immune profile differences of three groups of adolescents and young adults (ages 10-25 years): healthy controls (n = 39), at risk of major depressive disorder (MDD; at-risk, n = 33), and MDD with recent suicide behavior/ ideation (suicide behavior, n = 37). METHODS: Plasma samples were assayed for chemokines and cytokines using Bio-Plex Pro Human Chemokine 40-plex assay. Log-transformed cytokine and chemokine levels were compared after controlling for age, gender, body mass index, race, ethnicity, and C-reactive protein (CRP) levels. In post-hoc analyses to understand the effect of dysregulated immune markers identified in this exploratory analysis, their association with autoantibodies was tested in an unrelated sample (n = 166). RESULTS: Only levels of interleukin 4 (IL-4) differed significantly among the three groups [false discovery rate (FDR) adjusted p = 0.0007]. Participants with suicide behavior had lower IL-4 [median = 16.8 pg/ml, interquartile range (IQR) = 7.9] levels than healthy controls (median = 29.1 pg/ml, IQR = 16.1, effect size [ES] = 1.30) and those at-risk (median = 24.4 pg/ml, IQR = 16.3, ES = 1.03). IL-4 levels were negatively correlated with depression severity (r= -0.38, p = 0.024). In an unrelated sample of outpatients with MDD, levels of IL-4 were negatively correlated (all FDR p < 0.05) with several autoantibodies [54/117 in total and 12/18 against innate immune markers]. CONCLUSIONS: Adolescent and young adult patients with recent suicide behavior exhibit lower IL-4 levels. One biological consequence of reduced IL-4 levels may be increased risk of autoimmunity.

Editorial: Identifying Predictors of Treatment Response Trajectories of Suicidal Adolescents.

In this issue of the Journal, Abbott et al.1 present findings from an important secondary analysis of a randomized controlled trial that identifies predictors of treatment response. Previous research has highlighted the importance of varying trajectories of treatment response.2,3 There is a need to identify factors related to varied treatment outcomes. Determining those who will benefit from treatment compared to those who will not is an important step to personalizing treatments.

A Theory-Driven Investigation of the Association Between Emotion Dysregulation and Suicide Risk in a Clinical Adolescent Sample.

OBJECTIVE: Emotion dysregulation has been consistently linked to suicide ideation and attempt, but an explanatory model for this relationship has not been adequately investigated in adolescents. This study examined the concurrent relationship among emotion dysregulation, variables from the Interpersonal-Psychological Theory of Suicide (IPTS), and suicide risk (operationalized as a continuous variable that increases in intensity from nonspecific to active suicide ideation to suicide ideation with a plan) in a clinical adolescent sample. METHOD: A total of 151 adolescents (aged 12-17) were recruited from an inpatient psychiatry unit. Cross-sectional analyses were conducted to determine whether the relationship between emotion dysregulation and suicide risk was explained by the variables of perceived burdensomeness (PB), thwarted belongingness, and capability for suicide, as proposed by the IPTS. RESULTS: As hypothesized, the relationship between emotion dysregulation and suicide risk was explained by PB and capability for suicide. Depressive symptoms had an independent relationship with suicide risk after controlling for IPTS variables. CONCLUSIONS: The results from this study suggest that effective treatment strategies that reduce negative cognition tied to PB and depressive symptoms would address the most proximal variables related to suicide risk in adolescents. Enhancing emotion management would serve to maintain low levels of proximal influences on risk.
