The impact of adverse childhood experiences on adult depression severity and treatment outcomes.

BACKGROUND: Past research has established that adverse childhood experiences (ACE) are correlated with depression severity. The purpose of the present study was to examine how the number and nature of ACE exposure is associated with symptomatology and treatment outcomes in adult patients with treatment resistant depression (TRD). METHODS: Participants include 454 patients with a diagnosis of major depression or persistent depressive disorder. A one-way analysis of variance (ANOVA) was used to assess whether number of ACEs was associated with certain outcomes. Linear regression analyses were performed to model the associations between the five ACE subtypes (e.g., sexual abuse, physical violence, injury/illness, childhood grief, and parental upheaval) and symptom severity. Logistic regression analyses were then used to model the association between ACE subtypes and history of lifetime suicide attempt(s) and inpatient admission(s). RESULTS: Greater ACE exposure was associated with more severe symptomatology and treatment outcomes, but these differences were only seen between patients reporting no ACEs versus 3+ ACEs. Only the subtypes of violence and illness/injury were significant predictors of more severe symptomatology. The ACE subtypes of sexual trauma and violence uniquely predicted a lifetime suicide attempt(s), and only the subtype of sexual trauma predicted lifetime inpatient admission(s). LIMITATIONS: Limitations of the present study include retrospective adult assessments of childhood trauma, lack of data on ACE severity and timing, and the cross-sectional reporting of multiple study measures. CONCLUSIONS: Exposure to multiple ACE subtypes, particularly sexual and physical trauma, is associated with depression symptom severity, and history of suicidality, and inpatient admission(s).

Associations between childhood adversity, cognitive schemas and attenuated psychotic symptoms.

AIM: Childhood Adversity (CA) is strongly linked to psychotic-like symptoms across the clinical spectrum, though the mechanisms underlying these associations remain poorly understood. Negative cognitive schemas are associated with both CA exposure and psychotic symptoms, highlighting the possibility that cognitive schemas may be a key risk pathway. The purpose of this study was to determine whether negative cognitive schemas mediate the association between CA and specific attenuated psychotic symptoms in a large sample of clinical-high risk youth. Given the variability in experiences that encompass CA (eg, abuse, neglect and poverty) and attenuated psychotic symptoms (eg, suspiciousness and perceptual abnormalities), we also tested whether these associations differ by CA type (threat vs deprivation) and attenuated positive psychotic symptom domain. METHODS: Data were collected from 531 clinical-high risk youth between 12 and 35 years of age (mean = 18.80, SD = 4.21) who completed a clinical assessment that included the Structured Interview of Prodromal Syndromes (SIPS), Childhood Trauma and Abuse scale and questionnaires on cognitive schemas and depressive symptoms. RESULTS: No direct effects of threat or deprivation exposure on any of the psychotic symptom domains were found. However, there was a unique indirect effect of threat, but not deprivation, on delusional thinking and suspiciousness through negative cognitive schemas about others. CONCLUSION: Cognitive vulnerability in the form of negative schemas about others may be one mechanism linking childhood threat experiences and attenuated psychotic symptoms. The results underscore the importance of targeting negative schemas in interventions to mitigate psychosis risk.

Flattening the emotional distress curve: A behavioral health pandemic response strategy for COVID-19.

This article proposes a framework for managing the behavioral health impacts of the COVID-19 global pandemic. This framework aligns and should be integrated with an existing public health pandemic intervals model. It includes six phases of a behavioral health pandemic response strategy: preplanning, response readiness, response mobilization, intervention, continuation, and amelioration. The ways behavioral health specialists can capitalize on their competence in the leadership, prevention, education, service, research, and advocacy domains within each behavioral health pandemic response phase are articulated. Behavioral health expertise can help ensure a more comprehensive, effective pandemic response that facilitates the flattening of the curve of disease spread, along with the corresponding emotional distress curve. A case illustration, the Caring Communities (CC) initiative, is offered as an exemplar of action steps in the leadership, prevention, education, service, research, and advocacy domains that behavioral health professionals can take within each of the behavioral health pandemic response phases. Key CC action steps include providing support groups, offering virtual wellness breaks, participating in educational outreach, creating and disseminating wellness guides, launching and leading a virtual behavioral health clinic for health care staff, participating in behavioral health research and program evaluation, and engaging in advocacy initiatives aimed at improving behavioral health care and addressing and reducing health disparities. Finally, recommendations for optimizing behavioral health contributions to future pandemic responses are proffered. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Stress perception following childhood adversity: Unique associations with adversity type and sex.

Childhood adversity is associated with poor mental and physical health outcomes across the life span. Alterations in the hypothalamic-pituitary-adrenal axis are considered a key mechanism underlying these associations, although findings have been mixed. These inconsistencies suggest that other aspects of stress processing may underlie variations in this these associations, and that differences in adversity type, sex, and age may be relevant. The current study investigated the relationship between childhood adversity, stress perception, and morning cortisol, and examined whether differences in adversity type (generalized vs. threat and deprivation), sex, and age had distinct effects on these associations. Salivary cortisol samples, daily hassle stress ratings, and retrospective measures of childhood adversity were collected from a large sample of youth at risk for serious mental illness including psychoses (n = 605, mean age = 19.3). Results indicated that childhood adversity was associated with increased stress perception, which subsequently predicted higher morning cortisol levels; however, these associations were specific to threat exposures in females. These findings highlight the role of stress perception in stress vulnerability following childhood adversity and highlight potential sex differences in the impact of threat exposures.

Sleep problems and attenuated psychotic symptoms in youth at clinical high-risk for psychosis.

There has been growing interest on the effect of sleep problems on psychotic and prodromal symptoms. The current study investigated cross-sectional relations between sleep problems and attenuated psychotic symptoms in a large sample of 740 youth at Clinical High Risk (CHR) for psychosis in an attempt to replicate previous findings and assess whether findings from general population samples and psychotic samples extend to this CHR sample. Sleep problems were found to be significantly positively associated with attenuated psychotic symptom severity. Sleep problems were also found to be more closely associated with certain specific prodromal symptoms (e.g., suspiciousness and perceptual abnormalities) than other attenuated psychotic symptoms. Further, we found that depression mediated the cross-sectional association between sleep problems and paranoid symptoms only. This adds to a growing body of evidence suggesting the mediation role of depression is more pronounced for paranoid-type psychotic symptoms as compared to other psychotic symptoms (e.g., hallucinations).

Psychotropic medication effects on cortisol: Implications for research and mechanisms of drug action.

Stress and the hypothalamic-pituitary-adrenal (HPA) axis have been implicated in the etiology of a range psychiatric disorders; abnormalities in cortisol secretion are well documented in mood, anxiety, and psychotic disorders. There is, however, evidence that psychotropic medications affect HPA function, and are often a confound in research on the relation of cortisol secretion with psychiatric symptoms and syndromes. Psychotropic effects are particularly problematic in longitudinal research on individuals at clinical high risk (CHR) for serious mental illness, because they have the potential to obscure neurobiological mechanisms involved in crossing the threshold from CHR states to clinical disorders. This paper reviews the research literature on the relation of cortisol secretion with the three major classes of psychotropic medication that are most often prescribed; antipsychotics, antidepressants, and stimulants. The studies included in this review are those that measured both baseline and post-treatment cortisol. Taken together, most studies of antidepressants find that they are associated with a reduction in both basal and post-dexamethasone-CRH (DEX/CRH) cortisol, although some report no change. Similarly, antipsychotics, both typical and atypical, are found to reduce basal and DEX/CRH cortisol levels in most studies. Psychostimulant medications, in contrast, are associated with an increase in basal cortisol levels or no change. Effects of psychotropics on the cortisol awakening response (CAR) are less consistent. Implications of these effects for clinical research, especially studies of CHR populations, are discussed. Limitations of the research, due to variations in sample demographic and methodologic factors, are noted, and directions for future research are proposed.

Impact of childhood adversity on corticolimbic volumes in youth at clinical high-risk for psychosis.

Childhood adversity is among the strongest risk factors for psychosis-spectrum disorders, though the nature and specificity of the biological mechanisms underlying this association remains unclear. Previous research reveals overlaps in the volumetric alterations observed in both adversity-exposed individuals and in psychosis-spectrum populations, highlighting the possibility that deviations in corticolimbic gray matter development may be one mechanism linking adversity and psychosis. Given that childhood adversity encompasses a wide range of adverse experiences, there is also a critical need to examine whether these different types of experiences have unique effects on corticolimbic regions. This study examined the association between childhood adversity and cortical, hippocampal, and amygdalar volume in a large sample of youth at clinical-high risk (CHR) for psychosis. We utilized a novel differentiated adversity approach that distinguishes exposures along dimensions of threat (e.g., abuse) and deprivation (e.g., poverty, neglect) to test for differential associations. Participants were drawn from the North American Prodromal Longitudinal Study (NAPLS) and completed an MRI scan and a retrospective assessment of childhood adversity at baseline. We found that deprivation exposure, but not threat, was uniquely associated with smaller cortical volume and smaller right hippocampal volume in CHR youth. These associations were masked in a generalized risk model that utilized a total adversity score. The findings suggest that deprivation exposures during childhood contribute to the subtle volumetric reductions observed in clinical high-risk samples and highlight the importance of disentangling different dimensions of adversity.
