Perceptions of Helpful and Unhelpful Responses to Disclosures of Suicidality in a Sample of Mobile App Users

OBJECTIVE

Assessment and management of suicide risk is dependent on the individual at risk disclosing their suicidal thoughts. This study analyzed self-reported data collected via Youper, a mental-health app, to explore user experiences with suicide-related disclosure.

METHOD

2,952 international users who endorsed suicidal ideation reported on experiences with suicide-related disclosure. Differences in experiences were examined according to age, gender, and symptoms of psychopathology.

RESULTS

Just over half of users (56.17%) shared their suicidal thoughts. The primary reason for not sharing was thinking others would not understand. Of those who had disclosed their suicidal thoughts, 56.31% perceived the listener's response to be helpful, with listening and expressing care identified as most helpful. More severe depression and generalized anxiety symptoms were associated with higher disclosure likelihood, whereas higher borderline-personality and social-anxiety symptoms were associated with lower disclosure likelihood. Perceptions of what users found helpful when they disclosed suicidality varied by gender. Lack of understanding was the most frequently reported unhelpful response universally.

CONCLUSION

Findings suggest that listening and expressing care should be prioritized to maximize suicidal individuals' experiences of feeling supported. That said, gender and symptoms impact likelihoods of and experiences with disclosure, which should be considered when receiving suicide-related disclosure.HIGHLIGHTSNearly half of users shared suicidal thoughts and found listener responses helpful.Users most often endorsed listening as helpful and not understanding as unhelpful.Symptom severity and gender informed suicide-related disclosure experiences.

Reciprocal and Indirect Effects Among Intervention, Perceived Social Support, and Anxiety Sensitivity Within a Randomized Controlled Trial for Anxiety Disorders

Social support may facilitate adaptive reappraisal of stressors, including somatic symptoms. Anxiety sensitivity refers to negative beliefs about somatic symptoms of anxiety, which may influence one's perception of social support. Evidence-based treatment may impact these associations. The current longitudinal study evaluated reciprocal relationships between perceived social support and anxiety sensitivity, and explored indirect intervention effects, in a randomized controlled trial for anxiety disorders that compared cognitive behavioral therapy with or without medications (CALM) to usual care. Data collected over 18 months from 940 primary care patients were examined in random intercept cross-lagged panel models. There were significant reciprocal associations between perceived social support increases and anxiety sensitivity decreases over time. There were significant indirect effects from intervention to perceived social support increases through anxiety sensitivity decreases and from intervention to anxiety sensitivity decreases through perceived social support increases. These data suggest that, relative to usual care, CALM predicted changes in one construct, which predicted subsequent changes in the other. Secondary analyses revealed an influence of anxiety and depressive symptoms on reciprocal associations and indirect effects. Findings suggest that future treatments could specifically address perceived social support to enhance reappraisal of somatic symptoms, and vice versa.

The Role of Positive and Negative Aspects of Life Events in Depressive and Anxiety Symptoms

Negative or stressful life events are robust risk factors for depression and anxiety. Less attention has been paid to positive aspects of events and whether positivity buffers the impact of negative aspects of events. The present study examined positivity and negativity of interpersonal and non-interpersonal episodic life events in predicting anxiety and depressive symptoms in a sample of 373 young adults. Regressions tested main and interactive effects of positivity and negativity ratings of events in predicting symptom factors (Fears, Anhedonia-Apprehension (AA), General Distress (GD)) relevant to anxiety and depression. A significant interaction demonstrated that positivity protected against high levels of negativity of non-interpersonal events in predicting GD. A main effect of interpersonal negativity predicting higher AA was observed. Results for Fears were non-significant. Findings suggest that positivity of life events may buffer against negativity in predicting symptoms shared between anxiety and depression.

Influence of social support on cognitive reappraisal in young adults elevated on neuroticism

Social support offers protection from depression and anxiety, possibly through its beneficial effects upon cognitive reappraisal. The present study evaluates potential mechanisms of social support, utilizing a reappraisal task in 121 undergraduates elevated on neuroticism. Participants were instructed to reinterpret stressful images with (Social Condition) and without (Solo Condition) the reminder of a social support figure. Aversiveness, negative affect, and positive affect ratings, as well as written reappraisal responses, were collected trial-by-trial. Results indicated that participants reported lower aversiveness and negative affect and higher positive affect when reinterpreting images in the Social Condition compared to the Solo Condition. Analyses of adherence ratings of written reappraisals revealed that participants generated reinterpretations more in the Social Condition than in the Solo Condition. Exploratory mediation analyses indicated that Condition was indirectly associated with reappraisal efficacy as measured by aversiveness and affect ratings through reappraisal adherence. Results suggest that cognitive reappraisal with the influence of social support may be more effective than cognitive reappraisal without such social influence, and thus may be a suitable target for interventions for depression and anxiety.

Examining the indirect contributions of irritability and chronic interpersonal stress on symptoms of anxiety and depression in adolescents

BACKGROUND

Chronic interpersonal stress has been identified as predictive of anxiety and depression. However, more research is needed to understand predictors of chronic interpersonal stress and mediators of its relationship with anxiety and depression. Irritability, a transdiagnostic symptom closely related to chronic interpersonal stress, may provide more insight into this relationship. While some research has demonstrated that irritability is related to chronic interpersonal stress, directionality is unknown. A bidirectional relationship between irritability and chronic interpersonal stress was hypothesized, such that irritability mediates the relationship between chronic interpersonal stress and internalizing symptoms and chronic interpersonal stress mediates the relationship between irritability and internalizing symptoms.

METHODS

This study used three cross-lagged panel models to investigate the indirect effects of irritability and chronic interpersonal stress on anxiety and depression symptoms using data from 627 adolescents (68.9 % female, 57.7 % white) over a six-year period.

RESULTS

In partial support for our hypotheses, we found that the relationships between chronic interpersonal stress and both fears and anhedonia were mediated by irritability, and that the relationship between irritability and anhedonia was mediated by chronic interpersonal stress.

LIMITATIONS

Study limitations include some temporal overlap in symptom measurements, an irritability measure that has not been previously validated to measure the construct, and lack of a lifespan perspective.

CONCLUSIONS

More targeted approaches in intervention for both chronic interpersonal stress and irritability may improve prevention and intervention efforts to address anxiety and depression.

Longitudinal associations among dimensional symptoms of depression and anxiety and first onset suicidal ideation in adolescents

INTRODUCTION

Depression and anxiety are implicated in suicide risk, but the contributionof specific symptom dimensions within these disorders is not well understood. The present study examined longitudinal associations of transdiagnostic symptoms (General Distress[GD]) and unique symptom dimensions (Anhedonia-Apprehension [AA], Fears, and Narrow Depression [ND]) of depression and anxiety and suicidal ideation (SI).

METHODS

Data from 551 adolescents oversampled on high neuroticism were examined in a series of discrete-time survival analyses to predict first SI onset over an 8-year period.

RESULTS

Results indicate that GD, AA, and ND were independent predictors of increased likelihood of SI onset and remained significant when controlling for effects of fears. Furthermore, AA and GD remained significant when controlling for one another. ND effects reduced by 24% when adjusting for AA and 74% when adjusting for GD. Fears did not significantly predict SI onset.

CONCLUSION

Results suggest that broad levels of distress across depression and anxiety, deficits in positive affect, and elevated negative affect specific to depression increase the likelihood of suicidal thoughts. As such, attention to broader distress and a lack of pleasure, interest, and motivation-potentially more so than negative affect characterizing depression-are particularly important for addressing suicide risk in adolescents.

Perceived interpersonal competence as a predictor of clinical outcomes in a randomized controlled trial for social anxiety and employment

This study explored relationships among perceived interpersonal competence and demographic and work history variables in a randomized control trial for social anxiety disorder (SAD) that compared work-related group cognitive behavioral therapy plus vocational services (WCBT+VSAU) to vocational services only (VSAU-alone). Intervention effects of perceived interpersonal competence on treatment outcomes over 12 weeks were also examined. Data from 250 job seekers with SAD (59.2% Female; 40.8% Black/African American; 82.4% Non-Hispanic/non-Latino/a) were analyzed. We predicted negative relationships between perceived interpersonal competence and symptoms/impairment and that individuals with lower perceived interpersonal competence would benefit more quickly in WCBT+VSAU relative to VSAU-alone. Results indicated that perceived interpersonal competence did not vary by gender, race, ethnicity, homeless status, or employment history. There were no intervention effects of perceived interpersonal competence regarding social anxiety or overall functional impairment, but results supported negative relationships between perceived interpersonal competence and lower social anxiety and overall functional impairment in both conditions. Separately, perceived interpersonal competence moderated effects in the depression model such that there were faster declines in depression at lower perceived interpersonal competence levels in WCBT+VSAU, but not in VSAU-alone. Results indicate the value of attending to perceived interpersonal competence in interventions, which may result in mood benefits.

Antidepressant medication exposure and 5-HT1A autoreceptor binding in major depressive disorder

OBJECTIVE

We have previously reported higher brain serotonin 1A (5-HT_1A ) autoreceptor binding in antidepressant-naïve patients with Major Depressive Disorder (MDD) compared with healthy volunteers, and a decrease in binding in MDD after selective serotonin reuptake inhibitor (SSRI) treatment. This SSRI effect is also present in rodents administered SSRIs chronically. We therefore sought to determine the duration of antidepressant medication effects on 5-HT_1A receptor binding after medication discontinuation.

METHODS

Positron emission tomography (PET) imaging with the 5-HT_1A receptor radioligand [¹¹ C]WAY-100635 was performed in 66 individuals with current DSM-IV MDD to examine relationships between 5-HT_1A binding and time since most recent antidepressant treatment. All subjects were medication-free for at least 2 weeks prior to scanning. Thirty-two additional MDD comparison subjects were antidepressant naïve.

RESULTS

No differences in [¹¹ C]WAY-100635 binding were observed between antidepressant naïve and antidepressant exposed MDD groups in 13 a priori cortical and subcortical regions of interest, including raphe autoreceptors, assessed simultaneously in linear mixed effects models. Furthermore, [¹¹ C]WAY-100635 binding did not correlate with time off antidepressants in the antidepressant exposed patients considering these ROIs. The same results were observed when effects of treatment discontinuation of any psychotropic medication used to treat their depression was examined.

CONCLUSION

These results indicate that any antidepressant-associated downregulation of 5-HT_1A autoreceptor binding reverses within 2 weeks of medication discontinuation. Since this effect is hypothesized to mediate the antidepressant action of SSRIs, and perhaps other antidepressants, it suggests that patients who need ongoing treatment may relapse rapidly when medication is discontinued. Moreover, 2 weeks appears to be a sufficiently long washout of antidepressant medications for a reliable measure of illness-related binding levels.

Quantification of 5-HT1A and 5-HT2A receptor Binding in Depressed Suicide Attempters and Non-Attempters

OBJECTIVE

To determine serotonin system abnormalities related to major depression or previous suicidal behavior.

METHODS

[¹¹C]WAY100635, [¹⁸F]altanserin and positron emission tomography were used to compare 5-HT_1A and 5-HT_2A binding in MDD patients divided into eight past suicide attempters (>4yrs prior to scanning) and eight lifetime non-attempters, and both groups were compared to eight healthy volunteers.

RESULTS

The two receptor types differed in binding pattern across brain regions from each other, but there were no differences in binding between healthy volunteers and the two depressed groups or between depressed suicide attempters and non-attempters. No effects of depression severity or lifetime aggression were observed for either receptor.

CONCLUSION

Limitations of this study include small sample size and absence of high lethality suicide attempts in the depressed attempter group. No trait-like binding correlations with past suicide attempt or current depression were observed. Given the heterogeneity of nonfatal suicidal behavior, a larger sample study emphasizing higher lethality suicide attempts may find the serotonin biological phenotype seen in suicide decedents.

Neurocognitive performance predicts treatment outcome with cognitive behavioral therapy for major depressive disorder

The current study examined the contribution of baseline neuropsychological functioning to the prediction of antidepressant outcome with cognitive behavioral therapy (CBT) for Major Depressive Disorder (MDD). We hypothesized that depressed participants who were more neurocognitively intact and had less rigid, negative thinking would respond better to CBT. Thirty-one MDD patients completed a comprehensive neuropsychological battery before initiation of CBT. A subgroup also completed a probabilistic reversal learning task. Depression severity was assessed with the Beck Depression Inventory (BDI); rigid, negative thinking was assessed with the Dysfunctional Attitudes Scale (DAS) and the Automatic Thoughts Questionnaire (ATQ) throughout treatment. Remitters were compared to non-remitters. Paradoxically, eventual remitters performed generally worse across the neuropsychological battery considered as a whole. Univariate testing showed a significant difference on only a single measure, the Continuous Performance Test d', when corrected for multiple comparisons. Baseline rigid, negative thinking did not predict treatment outcome. Results suggest that the structure of CBT may particularly benefit individuals with mild depression-related neurocognitive difficulties during a depressive episode. Further research is needed to examine these patient characteristics and their potential contribution to the mechanisms of CBT efficacy.

Effects of anxiety on suicidal ideation: exploratory analysis of a paroxetine versus bupropion randomized trial

It is unclear whether anxiety increases or decreases suicidal risk. This may contribute to the lack of guidance on which antidepressant medications are best for suicidal depressed patients who present with high anxiety. This study explored whether anxiety predicts suicidal ideation in depressed individuals treated with paroxetine or bupropion. An 8-week double-blind trial comparing controlled-release paroxetine (N=36) versus extended-release bupropion (N=38) for effect on suicidal ideation and behavior in depressed patients with suicidal ideation, past attempt, or both found an advantage for paroxetine, but anxiety effects were not investigated. This secondary analysis explored the relationship, measured at baseline and weekly, of anxiety with suicidal ideation. Anxiety severity measured weekly correlated with suicidal ideation severity irrespective of treatment (P=0.012). Patients with high baseline anxiety showed a trend toward faster reduction of suicidal ideation with paroxetine compared with bupropion treatment (standard P=0.047; bootstrap P=0.077). The latter finding, if confirmed in larger samples, could enhance choice of antidepressant medication for suicidal, depressed patients presenting with high levels of anxiety.
