Assessing interpersonal and mood factors to predict trajectories of suicidal ideation within an inpatient setting

Trajectories of suicidal risk among individuals with first-episode psychosis: Relationship to recovery and symptoms

This study examined trajectories of suicide-risk and their relationship to symptoms, recovery, and quality of life over time. Data was obtained from the Recovery after an Initial Schizophrenia Episode Early Treatment Program (RAISE-ETP) study. 404 individuals with first-episode psychosis (FEP) completed measures of suicide-risk, depression, positive symptoms, recovery, and quality of life at baseline, 6mo, 12mo, 18mo, and 24mo. Latent class analysis was used to identify temporal trajectories of suicide-risk. General linear mixed models for repeated measures were used to examine the relationship between the latent trajectories of suicide-risk and clinical variables. Results identified three latent trajectories of suicide-risk (low-risk, worsening, and improving). The low-risk and improving classes experienced improvements in depression, positive symptoms, quality of life, and recovery over time. The worsening class experienced improvements in positive symptoms and quality of life, but no change in depression or recovery. These results suggest that some individuals with FEP are at risk for persistent depression and worsening suicide-risk during treatment despite experiencing improvements in positive symptoms and quality of life. These findings have important clinical implications, as persistent depression and worsening suicide-risk might be masked by the primary focus on positive symptoms and quality of life in most FEP clinics.

Gender differences in prevalence and associations between cognitive symptoms and suicidal ideation in patients with recurrent major depressive disorder: findings from the Chinese NSSD study

BACKGROUND

This study aimed to explore gender differences in associations between cognitive symptoms and suicidal ideation (SI) among patients with recurrent major depressive disorder (MDD).

METHODS

We recruited 1222 patients with recurrent MDD from the National Survey on Symptomatology of Depression (NSSD), a survey designed to investigate the symptoms experienced during current major depressive episodes in China. A four-point Likert questionnaire was used to assess the frequency of cognitive symptoms and SI in the past two weeks.

RESULTS

Gender differences in clinical features and cognitive symptoms of participants with recurrent MDD were found. Specifically, male patients had a higher prevalence of memory loss, decreased verbal output, indecisiveness, and impaired interpersonal relationships, while female patients exhibited a higher prevalence of impaired social and occupational functioning (all P < 0.05). No significant difference in SI prevalence was found between male and female patients. The logistic regression analysis revealed that in male patients, SI was associated with indecisiveness and impaired interpersonal relationships. In female patients, reduced verbal output and impaired social and professional functions were also associated with SI in addition to the above-mentioned variables.

CONCLUSION

The findings of gender differences in associations between cognitive symptoms and SI highlight the need to carefully assess gender-specific cognitive predictors of SI in patients with recurrent MDD. This has further implications for more targeted prevention and treatment strategies for SI based on gender.

Interpersonal Needs, Mental Pain, and Hopelessness in Psychiatric Inpatients with Suicidal Ideation

INTRODUCTION

Suicide is a leading cause of death worldwide and models may help the understanding of the phenomenon and ultimately reduce its burden through effective suicide prevention strategies. The Interpersonal Theory of Suicide and Shneidman's Model have tried to describe different unmet needs related to suicidal ideation. The study aims to assess the association between thwarted belongingness, perceived burdensomeness, and suicidal ideation in a sample of psychiatric inpatients and the mediating role of hopelessness and mental pain in this association.

METHODS

112 consecutive adult psychiatric inpatients were administered the Columbia Suicide Severity Rating Scale (C-SSRS), the Italian version of the Interpersonal Needs Questionnaire-15-I (INQ-15-I), the Physical and Psychological Pain Scale, and the Beck Hopelessness Scale (BHS).

RESULTS

Mediation models indicated a significant indirect effect of perceived burdensomeness (with thwarted belongingness as covariates) on suicidal ideation intensity with hopelessness as a mediator. When thwarted belongingness (controlling for perceived burdensomeness as a covariate) was included in a model as an independent variable, direct and indirect effects on suicidal ideation intensity were not significant.

CONCLUSIONS

Psychosocial interventions focusing on identifying and decreasing the perception of being a burden for others and the feeling hopeless could represent a powerful pathway for reducing suicidal ideation. Moreover, the attention toward unmet interpersonal needs may help increase and focus clinical discussions on risk factors, which may help engagement toward psychiatric care and downsize the stigma related to suicide. Raising awareness toward mental health topics is a goal of healthcare services globally.

Attentional control deficits and suicidal ideation variability: An ecological momentary assessment study in major depression

Suicidal behavior is associated with deficits in cognitive control; however, suicidal ideation (SI), a key precursor to suicidal behavior, has been less consistently linked to neuropsychological functioning. Additionally, no study to date has examined attentional control capacities in relation to variability in suicidal ideation, defined as fluctuation in SI intensity and duration across short periods of time. Prior research suggests that suicidal individuals with highly variable SI experience greater stress-responsive increases in SI and cortisol, potentially raising risk for suicidal behavior. Here, we examined attentional control capacities associated with SI variability and severity in ninety-five subjects with major depressive disorder. Variability and severity of SI and depressive affect were quantified using Ecological Momentary Assessment (EMA) over a 7-day period. Participants completed the Continuous Performance Task (CPT) and a computerized Stroop task for assessment of attentional control. EMA SI variability was associated with greater attentional interference on the Stroop task, and this was not accounted for by severity of SI, concurrently assessed depressive affect, or baseline depression. CPT performance was not related to SI variability or intensity. Findings highlight the utility of EMA methods in characterizing patterned experiences of SI and suggest that attentional control deficits may contribute to these characteristic patterns.

Modeling disease progression and treatment pathways for depression jointly using agent based modeling and system dynamics

Introduction

Depression is a common mental health condition that affects millions of people worldwide. Care pathways for depression are complex and the demand across different parts of the healthcare system is often uncertain and not entirely understood. Clinical progression with depression can be equally complex and relates to whether or not a patient is seeking care, the care pathway they are on, and the ability for timely access to healthcare services. Considering both pathways and progression for depression are however rarely studied together in the literature.

Methods

This paper presents a hybrid simulation modeling framework that is uniquely able to capture both disease progression, using Agent Based Modeling, and related care pathways, using a System Dynamics. The two simulation paradigms within the framework are connected to run synchronously to investigate the impact of depression progression on healthcare services and, conversely, how any limitations in access to services may impact clinical progression. The use of the developed framework is illustrated by parametrising it with published clinical data and local service level data from Wales, UK.

Results and discussion

The framework is able to quantify demand, service capacities and costs across all care pathways for a range of different scenarios. These include those for varying service coverage and provision, such as the cost-effectiveness of treating patients more quickly in community settings to reduce patient progression to more severe states of depression, and thus reducing the costs and utilization of more expensive specialist settings.

Implementation of a routine outcome monitoring and feedback system for psychotherapy in Argentina: A pilot study

Introduction

Routine Outcome Monitoring (ROM) has emerged as a strong candidate to improve psychotherapy processes and outcome. However, its use and implementation are greatly understudied in Latin-America. Therefore, the aim of the present pilot study conducted in Argentina was to implement a ROM and feedback system grounded on a psychometrically sound instrument to measure session by session outcome in psychotherapy.

Methods

The sample consisted of 40 patients and 13 therapists. At baseline, the patients completed the Patient Health Questionnaire-9 and the Generalized Anxiety Disorder-7, and they also completed the Hopkins Symptom Checklist-11 before each of the first five sessions. To estimate patient change during the first sessions, we conducted a quantitative analysis using Hierarchical Linear Models. Furthermore, we conducted a qualitative analysis using Consensual Qualitative Research to analyze therapist perception regarding the ROM and feedback system.

Results

Results showed a significant reduction in patients' symptomatic severity during the first five sessions. Additionally, baseline depression significantly predicted the estimated severity at the end of the fifth session. Feedback was given to the therapists after the first four sessions based on these analyses. With regard to the perception of the feedback system, clinicians underlined its usefulness and user-friendly nature. They also mentioned that there was a match between the information provided and their clinical judgment. Furthermore, they provided suggestions to enhance the system that was incorporated in a new and improved version.

Discussion

Limitations and clinical implications are discussed.

Comparing the role of perceived burdensomeness and thwarted belongingness in prospectively predicting active suicidal ideation

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.

Longitudinal mediation by perceived burden of the pathway from thwarted belonging to suicidal ideation

INTRODUCTION

Whereas the interpersonal theory of suicide entails the assumption that thwarted belongingness and perceived burdensomeness are equally important, mutually moderating, proximal causes of active ideation, evidence suggests these may not be co-moderating processes. We tested an alternative perspective, hypothesizing that burden mediates the longitudinal relationship of thwarted belonging with active ideation.

METHODS

A 6-week, four-wave prospective online survey was completed by 298 undergraduates. We tested cross-sectional and cross-lagged panel models (CLPM, with and without random effects) with belonging, burden, and ideation at 2-week lags, and post hoc models with burden as a concurrent mediator of ideation.

RESULTS

Approximately 28% of undergraduates reported active ideation at baseline. Cross-sectionally, thwarted belonging had no direct influence on ideation but indirectly affected ideation via burden. This result was not confirmed in the 2-week CLPM analyses. In post hoc analyses, we found belonging operated indirectly via later burden to influence contemporaneous ideation.

CONCLUSIONS

Findings suggest thwarted belonging influences active ideation indirectly via perceived burden. The effect of burden as a mediator appears to depend on its temporal proximity to ideation. Future research should delimit the period during which perceived burden is an active mediator, accommodate dual-process approaches, and explore other mediation alternatives to co-moderation.

An experimental investigation of the influence of loneliness on changes in belongingness and desire to escape

OBJECTIVE

Loneliness is a well-established risk factor for suicide in young adults, but the mechanisms involved are still unclear. Drawing on the Interpersonal Theory of Suicide, the Evolutionary Model of Loneliness, and Prospect Theory, we examined if high and low levels of loneliness are associated with different patterns of response to losses or gains of belongingness.

METHODS

A sample of 188 students completed the UCLA-Loneliness scale (version 3) and measures of suicide risk. Participants in the top and bottom tertiles of loneliness scores completed a computerized task designed to induce changes (gains, losses) or consistency in risk factors for suicide (belongingness, burdensomeness) over time, and examined the effect on desire to quit the task.

RESULTS

The results showed that the high loneliness group exhibited a larger magnitude of effect on desire to quit from gaining belongingness than for losing belongingness. In contrast, the low loneliness group showed a larger change in desire to quit from losing belongingness than gaining belongingness.

CONCLUSION

The findings provide preliminary experimental support for distinct profiles of suicide risk based on prevailing levels of loneliness. The findings are discussed in relation to a need for increased precision in theoretical models of suicide and loneliness.

Predictors of suicidal ideation trajectories in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study

A better understanding of suicidal ideation (SI), including patterns of SI, may help elucidate links between depression, SI, and suicidal behavior. This study sought to identify trajectories of SI in a large, community-based clinical trial of participants with major depressive disorder (MDD) and to investigate the relationships between these trajectories and predictors of interest, including anxiety and anhedonia. A longitudinal latent class analysis was conducted in 3923 participants enrolled in Level 1 of the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study of citalopram for the treatment of MDD. An unconditional latent class analysis was conducted using SI at study weeks 0, 2, 4, 6, and 9 as the indicators. A multinomial regression was then conducted with SI trajectory as the outcome and anhedonia, severity of depressive symptoms, atypical depression, anxiety, history of suicide attempt, history of substance abuse, history of trauma, and other covariates as the predictors. Four SI trajectories were identified: 1) variable SI; 2) little-to-no SI; 3) persistent SI; and 4) improving SI. Compared to the little-to-no SI trajectory, those with more severe anhedonia were more likely to experience persistent SI, while those with more severe anxiety were more likely to experience improving SI. Factors that distinguish SI trajectories, such as anxiety and anhedonia, may be critical targets for intervention or profiles for prognosis.

Distress tolerance as a moderator of the dynamic associations between interpersonal needs and suicidal thoughts

BACKGROUND

Identifying the interaction between dispositional and dynamic risk factors is necessary in understanding, predicting, and managing suicide risk. Interpersonal factors have consistently been linked to suicidal ideation over short-term periods. Additionally, distress tolerance may be a relevant dispositional protective factor against stressful events.

METHODS

Seven hundred and seventeen psychiatric inpatients (Male = 30.31%, Average Age = 40.71 years, Min = 14, Max = 82) self-reported their distress tolerance at hospital admission, and interpersonal needs and suicidal ideation on a daily basis. Dynamic structural equation modelling was used to examine whether within-level dynamics were moderated by distress tolerance.

RESULTS

Both perceived burdensomeness and thwarted belongingness were significantly associated with same-day suicidal ideation. Higher distress tolerance was associated with weaker daily associations between suicidal ideation and both perceived burdensomeness and thwarted belongingness. Distress tolerance was also associated with lower variability in suicidal ideation. Moderating effects were also evident when lifetime suicide attempts were added as a covariate, which was associated with stronger associations between interpersonal dysfunction and suicidal ideation, and higher variability in ideation.

CONCLUSIONS

Distress tolerance may be important to consider when examining the dynamic relationships between suicidal ideation and proximal factors. Psychotherapy that specifically targets distress tolerance may be effective in reducing reactivity to interpersonal stressors.

Effectiveness of school-based preventive programs in suicidal thoughts and behaviors: A meta-analysis

BACKGROUND

Suicidal thoughts and behaviors (STBs) among adolescents have hardly decreased despite preventative efforts. School-based prevention programs could have a great reach, yet suicide prevention is not an easy topic to address. To increase acceptability of school-based suicide prevention, it is important to evaluate whether programs that target known risk factors of STBs, such as depression, could be equally effective.

METHODS

We conducted a systematic literature search in major electronic databases. Outcomes were suicidal ideation and behaviors. Multivariate random effects meta-regression-analyses were conducted.

RESULTS

Eleven primary studies met the inclusion criteria, totalling 23,230 participants. The post-test effect size was small for both suicidal ideation (g = 0.15) and suicidal behaviors (g = 0.30). Meta-regression indicated that targeting known risk factors of STBs was not a significant modifier of effect size for ideation, indicating equal effectiveness. However, it was significant modifier of effect for behaviors, but only one intervention targeted know risk factors. Effects at follow-up (3-12 months) were also significant but small for both outcomes.

LIMITATIONS

Substantial heterogeneity between studies was noted. Only few and small sample size studies could be included that targeted known risk factors of STBs. Therefore, these results should be interpreted with caution.

CONCLUSIONS

School-based prevention of STBs shows some promise within three months post-test assessments, and potentially also have effects that are sustained over time. More studies are needed to make conclusions regarding school-based interventions that target risk factors of STBs.

Measurement-Based and Data-Informed Psychological Therapy

Outcome measurement in the field of psychotherapy has developed considerably in the last decade. This review discusses key issues related to outcome measurement, modeling, and implementation of data-informed and measurement-based psychological therapy. First, an overview is provided, covering the rationale of outcome measurement by acknowledging some of the limitations of clinical judgment. Second, different models of outcome measurement are discussed, including pre-post, session-by-session, and higher-resolution intensive outcome assessments. Third, important concepts related to modeling patterns of change are addressed, including early response, dose-response, and nonlinear change. Furthermore, rational and empirical decision tools are discussed as the foundation for measurement-based therapy. Fourth, examples of clinical applications are presented, which show great promise to support the personalization of therapy and to prevent treatment failure. Finally, we build on continuous outcome measurement as the basis for a broader understanding of clinical concepts and data-driven clinical practice in the future. Expected final online publication date for the Annual Review of Clinical Psychology, Volume 18 is May 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Prediction and network modelling of self-harm through daily self-report and history of self-injury

BACKGROUND

Self-harm is a significant public health issue, and both our understanding and ability to predict adverse outcomes are currently inadequate. The current study explores how preventative efforts could be aided through short-term prediction and modelling of risk factors for self-harm.

METHODS

Patients (72% female, M_age = 40.3 years) within an inpatient psychiatric facility self-reported their psychological distress, interpersonal circumstances, and wish to live and die on a daily basis during 3690 unique admissions. Hierarchical logistic regressions assessed whether daily changes in self-report and history of self-harm could predict self-harm, with machine learning used to train and test the model. To assess interrelationships between predictors, network and cross-lagged panel models were performed.

RESULTS

Increases in a wish to die (β = 1.34) and psychological distress (β = 1.07) on a daily basis were associated with increased rates of self-harm, while a wish to die on the day prior [odds ratio (OR) 3.02] and a history of self-harm (OR 3.02) was also associated with self-harm. The model detected 77.7% of self-harm incidents (positive predictive value = 26.6%, specificity = 79.1%). Psychological distress, wish to live and die, and interpersonal factors were reciprocally related over the prior day.

CONCLUSIONS

Short-term fluctuations in self-reported mental health may provide an indication of when an individual is at-risk of self-harm. Routine monitoring may provide useful feedback to clinical staff to reduce risk of self-harm. Modifiable risk factors identified in the current study may be targeted during interventions to minimise risk of self-harm.

Predicting suicidal ideation in a longitudinal high-risk sample: Multilevel analyses and 12-month trajectories

BACKGROUND

The Interpersonal Theory of Suicide states that suicidal ideation (SI) results from perceived burdensomeness (PB) and thwarted belongingness (TB). Cross-sectional studies found associations with SI. This study examined the prospective prediction of SI.

METHODS

Three hundred and eight inpatients reporting severe SI or a recent suicide attempt were assessed four times within 12 months. The prediction of SI was examined using multilevel analyses, group comparisons, and logistic regression analyses.

RESULTS

Cross-sectionally, PB and TB were associated with SI. Prospectively, neither PB nor TB predicted SI. We found no autocorrelation of SI over time. Patients with persistent and fluctuating SI reported higher PB at T0. PB predicted the persistence of SI over 12 months.

CONCLUSION

Results emphasize cross-sectional associations between PB, TB, and SI. PB and TB could not predict the intensity of SI over time. SI did not predict itself over time. PB was associated with a persistent trajectory of SI over 12 months.

Prevalence and predictors of suicidal thoughts and behaviours among Australian police and emergency services employees

OBJECTIVE

This study presents rates of suicide thoughts and behaviours of police and emergency services personnel around Australia. In addition, it examines personal (i.e. mental health, substance use) and working environment risk and protective factors.

METHOD

A stratified random sample of personnel from 33 Australian emergency services organisations were invited to participate in a mental health and wellbeing survey. In total, 14,868 Australian ambulance, fire and rescue, police and state emergency services employees participated and self-reported any suicidal thoughts, plans and/or attempts in the 12 months prior to the survey or at any stage in their life. Logistic regressions assessed factors associated with suicidal thoughts and behaviours.

RESULTS

Employees reported notably higher rates of suicidal thoughts and plans than the general Australian adult population, but not attempts. Male, single/divorced, non-heterosexual or longer-serving employees reported higher rates of suicidal thoughts and behaviours across each sector. Perceptions of stigma regarding mental health conditions from others in the workplace, negative impact of work on one's private life and low meaning of work were associated with suicidal thoughts, while bullying significantly differentiated who planned and attempted suicide from those who reported suicidal thoughts only. Higher resilience and social support were associated with lower suicidal thoughts, while intermittent explosive anger and illegal drug use were associated with higher rates of suicidal thoughts. Post-traumatic stress disorder symptoms significantly differentiated who planned suicide, while misuse of prescription drugs and psychological distress differentiated who attempted suicide from those who only reported suicidal thoughts.

CONCLUSION

Amid inherently stressful occupations, it is important that workplaces function in a way that supports their personnel. Access to mental health services should be promoted and readily available to personnel.

Interpersonal theory of suicide: prospective examination

BACKGROUND

The interpersonal theory of suicide (IPTS) is one of the most intensively researched contemporary theories on the development of suicidal ideation and behaviour. However, there is a lack of carefully conducted prospective studies.

AIMS

To evaluate the main predictions of the IPTS regarding the importance of perceived burdensomeness, thwarted belongingness and capability for suicide in predicting future suicide attempts in a prospective design.

METHOD

Psychiatric in-patients (n = 308; 53.6% (n = 165) female; mean age 36.82 years, s.d. = 14.30, range 18-81) admitted for severe suicidal ideation (n = 145, 47.1%) or a suicide attempt completed self-report measures of thwarted belongingness, perceived burdensomeness, capability for suicide, hopelessness, depression and suicidal ideation as well as interviews on suicide intent and suicide attempts and were followed up for 12 months. Logistic regression and receiver operating characteristics (ROC) analysis were conducted.

RESULTS

The interaction of perceived burdensomeness, thwarted belongingness and capability for suicide was not predictive of future suicide attempts, but perceived burdensomeness showed a significant main effect (z = 3.49, P < 0.01; OR = 2.34, 95% CI 1.59-3.58) and moderate performance in screening for future suicide attempts (area under the curve AUC = 0.729, P < 0.01).

CONCLUSIONS

The results challenge the theoretical validity of the IPTS and its clinical utility - at least within the methodological limitations of the current study. Yet, findings underscore the importance of perceived burdensomeness in understanding suicidal ideation and behaviour.

How Is the Presence of Company Related to Thwarted Belongingness in Real Time? Taking a Closer Look at the Conceptualization of the Construct of the Interpersonal Theory of Suicide

(1) Background: The role of thwarted belongingness (TB) in predicting suicidal ideation, as originally assumed by the Interpersonal Theory of Suicide, is repeatedly challenged by empirical findings. This could be due to an inadequate conceptualization of the construct of TB that is assumed to be influenced by intrapersonal and interpersonal factors. (2) Methods: We examined the associations of TB with intrapersonal variables related to depression, and with interpersonal variables related to an individual’s actual social environment. We analyzed data from an ecological momentary assessment study in psychiatric inpatients with depressive disorders. N = 73 participants rated momentary TB, depressive affect and status of company up to 10 times per day, over a period of six days, on smartphones. (3) Results: TB was lower when assessed while participants were in company compared to when they were alone, and the more desired the company was, the less TB was experienced. Individuals who had a partnership experienced less momentary TB. Furthermore, higher levels of momentary depressive affect, as well as more stable levels of depression, were related to higher levels of TB, and the relation between the presence of company and TB was weaker for more depressed persons. (4) Conclusions: Our findings can be seen as evidence that both intrapersonal and interpersonal factors relate to TB, and thus support the conceptualization of TB as proposed by the Interpersonal Theory of Suicide.
