“…Our findings on RSA reactivity seem inconsistent with results from two earlier studies: Crowell et al () reported that female self‐harming adolescents had elevated RSA reactivity to a sad film compared to controls, while Giletta et al () found that high levels of RSA reactivity to a stressor predicted suicidal ideation 9 months later. The discrepancy between the present findings and the just‐noted reports is likely to reflect substantial differences in sample characteristics, definitions of STBs, and data analytic approaches.…”

“…First, all suicidal adolescents in our study had been clinically ascertained and were previously depressed. In contrast, suicidal subjects in the other studies either did not receive a psychiatric diagnostic assessment (Crowell et al, 2005) or included community-based subjects (Giletta et al, 2017). Second (not raw) scores to analyze physiological data.…”

“…Likewise, James et al () found that children with a history of suicidal ideation did not exhibit the typical RSA decrease during a (presumably stressful) parent‐child interaction task. However, suicidal adolescents also have been reported to exhibit greater decrease in RSA than controls when responding to a sad film (Crowell et al, ) as well as laboratory stressors (Giletta et al, ; Kaufman et al, ). Thus, the literature on RSA and STBs is equivocal.…”

“…In summary, emotion regulation is considered as a key to understanding STBs, which can be studied using physiological measures. However, most work in this area has focused on suicidal ideation or suicide attempts (e.g., Chang et al, ; Crowell et al, ; Giletta et al, ; James et al, ; Wilson et al, ), while the Diagnostic and Statistical Manual of Mental Disorders (DSM‐IV; American Psychiatric Association, ) specifies four categories of STBs: recurrent thoughts of death, recurrent suicidal ideation, suicide plan, and suicide attempt. Therefore, in the present study, we sought to address the full range of STBs.…”

Autonomic correlates of lifetime suicidal thoughts and behaviors among adolescents with a history of depression

Suicidal thoughts and behaviors (STBs) have been associated with emotion dysregulation and atypical responses to affective and stressful stimuli. To investigate the psychophysiology involved, we measured changes in respiratory sinus arrhythmia (RSA) and cardiac pre‐ejection period (PEP; indexing parasympathetic and sympathetic functioning, respectively) in response to stressful‐ and sadness‐eliciting laboratory probes. Our sample included adolescents with a history of depression and STBs (n = 177), adolescents with a history of depression but no history of STBs (n = 47), and healthy controls (n = 175). The outcome of interest was the most severe form of clinician‐rated STBs across the subject’s lifetime. In partial support of our hypotheses, during the stressful task, adolescents with a history of depression and STBs did not evidence the RSA decrease that was exhibited by controls and displayed greater PEP shortening compared to ever‐depressed adolescents with no lifetime STBs. No group differences were found in either RSA or PEP reactivity to the sadness‐eliciting stimulus. As expected, severity of STBs was positively correlated with the extent of PEP shortening during the stressful task. The results suggest that adolescents with a history of depression and STBs experience blunted parasympathetic responses to stress along with compensatory efforts. Our findings contribute to a better understanding of STBs among youths and underscore that future studies should examine physiological risk factors for these psychopathological outcomes.

Objective This study tests a novel, within-person model that reexamines depression and stress as risk factors for suicidal ideation and behavior among adolescent girls with and without sexual/physical abuse histories. Method This longitudinal study includes data from 220 adolescent girls between 12 and 16 years (M age = 14.69 years, SD = 1.37; 61% White). At baseline, adolescents reported the presence or absence of prior abuse as part of a clinical interview. At baseline and every 3 months for 18 months, adolescents completed measures of suicidal ideation and behavior, depressive symptoms, and stress. Results Multilevel models examined within-person mean, and deviations from within-person mean, depression and stress and their interactions with abuse as predictors of suicidal ideation and behavior. In addition to within-person mean depression, both higher-than-usual depression (OR = 1.99) and higher-than-usual stress (OR = 1.53) predicted greater risk of suicidal ideation at each follow-up assessment. Periods of higher-than-usual stress (1 SD increase) and periods of higher-than-usual depression (1 SD increase) were associated with an 82% and 57% increase in the odds of suicidal behavior, respectively, but only among those with abuse histories. Conclusion Depression, stress, and abuse are well-known risk factors for suicidal ideation and behavior; however, it has been unclear for whom, and when, these factors have their greatest impact. These results show that depression and stress are potent risk factors among those with a history of abuse and that within-person elevations in these risk factors signal increased short-term risk of suicidal ideation and behavior.

Autonomic dysregulation and self‐injurious thoughts and behaviours in children and young people: A systematic review and meta‐analysis

et al. 2023

BackgroundSelf‐injurious thoughts and behaviours (SITBs) have been associated with dysfunction of the Autonomic Nervous System (ANS) in children and young people, suggesting that objective ANS measures may aid assessment of suicide risk, but a systematic synthesis of this literature is currently lacking.MethodsFollowing a pre‐registered protocol (PROSPERO CRD42022327605), we conducted a systematic search of PubMed, Medline, Embase, PsycINFO, and Web of Science, for empirical studies published until 10th May 2022 that compared indices of ANS functioning in individuals aged 0–25 years with versus without SITBs, or reported continuous associations between ANS measures and SITBs. Study quality was assessed with the Newcastle‐Ottawa Scales. Pooled effect sizes (Hedge's g) were estimated with random‐effects meta‐analytic models.ResultsTwenty studies (1979 participants) were included in our systematic review, with 16 included in meta‐analyses. Results suggested that SITBs were associated with altered cardiac indices of arousal (g = −0.328, p < 0.001), which was driven by lower heart rate variability in individuals with SITBs (g = −0.375, p = 0.025). Overall results for electrodermal activity were not significant (g = 0.026, p = 0.857), but subgroup analyses showed increased activity in studies of individuals who engaged specifically in non‐suicidal self‐harm (g = 0.249, p = 0.014) but decreased activity in the remaining studies (g = −0.567, p = 0.004).ConclusionsOur systematic review and meta‐analysis found evidence of reduced parasympathetic regulation as well as more tentative evidence of altered electrodermal activity in children and young people displaying SITBs. Future longitudinal studies should test the clinical utility of these markers for detecting and monitoring suicide risk.
