RESUMEN

Behavioral genetic analyses have not demonstrated robust, unique, genetic correlates of hippocampal subregion volume. Genetic differentiation of hippocampal longitudinal axis subregion volume has not yet been investigated in population-based samples, although this has been demonstrated in rodent and post-mortem human tissue work. The following study is the first population-based investigation of genetic factors that contribute to gray matter volume along the hippocampal longitudinal axis. Twin-based biometric analyses demonstrated that longitudinal axis subregions are associated with significant, unique, genetic variance, and that longitudinal axis subregions are also associated with significant shared, hippocampus-general, genetic factors. Our study's findings suggest that genetic differences in hippocampal longitudinal axis structure can be detected in individual differences in gray matter volume in population-level research designs.

RESUMEN

Studies demonstrate that individuals with diagnoses for Major Depressive Disorder (MDD), Post-traumatic Stress Disorder (PTSD), and Schizophrenia (SCZ) may exhibit smaller hippocampal gray matter relative to otherwise healthy controls, although the effect sizes vary in each disorder. Existing work suggests that hippocampal abnormalities in each disorder may be attributable to genetic liability and/or environmental variables. The following study uses baseline data from the Adolescent Brain and Cognitive Development[Formula: see text] Study (ABCD Study[Formula: see text]) to address three open questions regarding the relationship between genetic risk for each disorder and hippocampal volume reductions: (a) whether polygenic risk scores (PGRS) for MDD, PTSD, and SCZ are related to hippocampal volume; (b) whether PGRS for MDD, PTSD, and SCZ are differentially related to specific hippocampal subregions along the longitudinal axis; and (c) whether the association between PGRS for MDD, PTSD, and SCZ and hippocampal volume is moderated by sex and/or environmental adversity. In short, we did not find associations between PGRS for MDD, PTSD, and SCZ to be significantly related to any hippocampal subregion volumes. Furthermore, neither sex nor enviornmental adversity significantly moderated these associations. Our study provides an important null finding on the relationship genetic risk for MDD, PTSD, and SCZ to measures of hippocampal volume.

RESUMEN

BACKGROUND: Although effective treatments are available to address the cognitive deficits experienced by individuals with first-episode psychosis, provision of such treatments within Coordinated Specialty Care (CSC) programs is rare. One factor that may contribute to this is uncertainty about the cost implications of providing cognitive-enhancing treatments within the American mental healthcare system. The aim of this study is to complete a naturalistic evaluation of the cost utility of incorporating two different cognitive-enhancing interventions within an American CSC program. METHODS: Participants included 66, predominately white (75.38%), individuals with first-episode psychosis (19 women and 47 men) with a mean age of 22.71 years. Quality adjusted life years (QALYs) and cost of care were tracked among these individuals during their participation in a CSC program. These data were compared among three groups of participants during their first six months of care: (i) individuals who participated in metacognitive remediation therapy (MCR), (ii) individuals who participated in computerized cognitive remediation (CCR), and (iii) individuals who participated in no cognitive-enhancing intervention. RESULTS: Participation in MCR, but not CCR, was associated with larger gains in QALYs than participation in no cognitive-enhancing intervention within a CSC program. Moreover, data support the cost utility of MCR as compared to CCR or no-cognitive enhancing intervention within a CSC program. Conversely, CCR did not appear to be a cost-effective addition to CSC services. CONCLUSIONS: Our results highlight the potential cost utility of incorporating MCR within CSC programs for individuals with first-episode psychosis. However, given study limitations, these results should be interpreted cautiously until replicated by large, randomized controlled trials.

RESUMEN

Background: Metacognitive skills training (MST) is often integrated into cognitive remediation programs for psychosis. Social cognition - the mental processes underlying social perception and behavior - is robustly related to outcomes in psychosis and is increasingly addressed with targeted treatments. Though metacognition and social cognition are related constructs, little is known about how MST may influence social cognition among individuals with psychosis participating in broad-based, non-social cognitive remediation. Methods: Individuals with first-episode psychosis who completed six months of metacognitive remediation (MCR; n=12) were compared to a historical control group who received six months of computerized cognition remediation (CCR; n=10) alone (ClinicalTrials.gov Identifier NCT01570972). Results: Though individuals receiving MCR experienced gains in emotion processing and theory of mind, these changes were not significantly different when compared to individuals receiving CCR. MST did not contribute to social cognitive change in the context of CCR. Discussion: Though MST may be relevant to facilitating social cognitive gains within broader cognitive remediation programs for first-episode psychosis, these benefits are limited and may not exceed those conferred by standard cognitive remediation. Opportunities for investigation of other potential mechanisms of social cognitive response to interventions remain.

RESUMEN

Objective: There is emerging evidence that greater cognition is associated with increased risk for suicide among individuals with psychosis. Given this association, concerns have been raised that cognitive interventions might actually increase risk for suicide in this population. Therefore, the present study investigated the cross-sectional and longitudinal relationship between cognition and suicide risk among individuals with first-episode psychosis. Method: Sixty-five participants completed measures of suicide risk, depression, and cognition at baseline and 6 months. Within-subject mediation analysis was used to examine the indirect effect of cognition on suicide risk. Within-subject moderation analysis was used to examine whether participation in cognitive enhancing intervention (e.g., computerized drill-and-practice cognitive remediation and metacognitive remediation therapy) moderated changes in suicide risk. Results: Consistent with prior studies, our cross-sectional results suggest that greater cognition is associated with increased risk for suicide. However, this effect was limited in scope, as we found that verbal learning was the only cognitive domain associated with suicide risk in our sample. Results from our longitudinal analyses show that changes in depressive symptoms, but not changes verbal learning, mediate changes in suicide risk during the first 6 months of treatment. In addition, participation in cognitive enhancing interventions did not moderate changes in suicide risk. Conclusions and Implications for Practice: Our results suggest that cognition is a correlate, or a proxy risk factor, rather than a causal risk factor for suicide. Although these findings contradict previously raised concerns that cognitive interventions might unintentionally increase risk for suicide, ongoing assessment is warranted and additional research is needed.

RESUMEN

AIM: Metacognitive remediation therapy (MCR) has been shown to help individuals with first-episode psychosis experience improvements in cognition, social functioning, vocational/educational functioning and quality of life. The theoretical model underlying MCR has yet to be empirically validated. METHODS: Seventy-three individuals with first-episode psychosis completed measures of metacognition and cognition at enrollment and after 6-months of care at a specialized clinical program for individuals with first-episode psychosis. Among this group, we compared changes in these variables between the 21 individuals who opted to participate in MCR and the 52 individuals who did not participate in MCR. RESULTS: Improvements in metacognition were moderated by MCR treatment participation. Consistent with the MCR theoretical model of change, increases in metacognition mediated the relationship between treatment and longitudinal changes in cognition. CONCLUSIONS: Our findings suggest that the benefits of MCR on cognitive functioning may stem, in part, from the ability of MCR to produce improvements in metacognitive functioning.

RESUMEN

AIM: Deficits in motivation are present early in the course of psychotic disorders. However, growing data have highlighted important heterogeneity in motivation among individuals with psychosis, suggesting that this variable may not be a unitary concept. Outside of the psychosis literature, research on self-determination theory has identified three motivational orientations that guide the initiation and regulation of behaviour: autonomous, controlled and impersonal. Thus, our study goal is to investigate the longitudinal course of motivational orientations among individuals participating in a specialized clinical service for individuals with first-episode psychosis (ie, coordinated specialty care: CSC). METHODS: Forty-one individuals with first-episode psychosis participating in CSC completed assessments of motivation orientations at enrolment and after 6 months of care. RESULTS: Whereas there were no changes in controlled or impersonal orientations over the first 6-months of care, individuals with first-episode psychosis reported an increase in autonomous orientations. Moreover, while individuals with first-episode psychosis reported lower autonomous orientations at enrolment as compared to individuals without psychosis, after 6 months of care, ratings of autonomous orientations among individuals with first-episode psychosis were equivalent to those of individuals without psychosis. CONCLUSIONS: Although the results should be interpreted cautiously given the uncontrolled study design, the results suggest that the benefits of participation in early intervention services for psychosis may extend to improvements in motivation.

RESUMEN

AIM: Although suicidal ideation may decrease over the course of participation in specialized clinical programmes for first-episode psychosis (FEP), it is unclear whether such improvements exceed those that occur during treatment as usual. Clarifying the mechanisms underlying reductions in suicidal ideation and behaviour among individuals with first-episode psychosis may highlight important strategies through which specialized clinical programmes can increase the potency of their services to reduce suicidality among this high-risk population. Thus, the goal of this study is to evaluate the longitudinal relationships between suicidality and social problem-solving skills among individuals with FEP participating in Coordinated Specialty Care. METHODS: Within-subject mediational and moderational models were applied to explore the interrelationships and longitudinal course of suicidality, social problem-solving and duration of untreated psychosis (DUP). RESULTS: Over the first 6 months of care, individuals with FEP experienced improvements in social problem-solving skills that were found to mediate concurrent reductions in suicidality. Although longitudinal changes in social problem-solving skills were moderated by DUP, these results should be interpreted cautiously as they may stem in part from a relatively limited number of participants with longer durations of illness. CONCLUSIONS: Improvements in social problem-solving skills during participation in CSC may facilitate reductions in suicidality. Treatments targeting suicidality among individuals with FEP may thus benefit from working to enhance social problem-solving skills among these individuals. Further research is needed to clarify if and how DUP may influence the magnitude of change in social problem-solving skills during participation in CSC.

RESUMEN

Individuals with first-episode psychosis (FEP) are at elevated risk for suicide. The current study explored the applicability of the Interpersonal-Psychological Theory of Suicide (IPTS) as a model for understanding suicide in FEP. Thirty-nine individuals with FEP completed measures of thwarted belongingness, perceived burdensomeness, acquired capability for suicide, and suicidal ideation. Results indicate that participants with recent suicidal ideation have greater levels of perceived burdensomeness and thwarted belongingness than those without recent suicidal ideation. In contrast, the interaction of IPTS variables did not predict the severity of suicidal ideation across the entire sample. These findings suggest that burdensomeness and belongingness differentiate between individuals with and without suicidal ideation, although these constructs might be less useful in predicting the severity of suicidal ideation among individuals with psychosis. Further research is needed to understand both transdiagnostic and unique risk factors that contribute to the high rates of suicide in this population.

RESUMEN

Social functioning is diminished among people early in the course of psychotic illnesses, and is likely influenced by the negative symptoms that accompany these disorders, including changes in motivation and experience of pleasure. Though social impairments have a deleterious impact on functioning, socialization is a multifaceted behavior and little is known about how the various aspects may influence social functioning and social quality of life among people with first-episode psychosis. In the present study, we investigated the associations of specific aspects of social motivation and behavior with social functioning and social quality of life in a group of 54 young people (aged 15 to 35) with first-episode psychosis. Though different aspects of social motivation and behavior correlated positively with one another, social motivation for peer interactions was uniquely associated with social functioning and social quality of life - including when a broad measure of negative symptoms was considered within the same model. When these same associations were examined longitudinally, social motivation for peer interactions again emerged as a unique predictor of change in social functioning over 6 months. Our results suggest that the unique contribution of aspects of social motivation has implications for treatment, including the importance of developmentally-informed interventions to improve peer socialization in youth and young adults with psychosis.

RESUMEN

Objective: Psychotic disorders are serious illnesses that are most amenable to early intervention. Though inpatient units are typically the first care setting for young people with psychosis, almost all early intervention work has been limited to outpatient settings. Social difficulties are a core feature of psychotic illnesses, and despite need for empirically supported social-skills treatments there are few interventions intended specifically for the developmental phase during which psychosis manifests (i.e., late teenage to early adult years). Method: Our group implemented an adapted social-skills training intervention (SST) designed for young adults on a psychiatric inpatient unit. Nineteen young adult inpatients (aged 18-35) with psychosis participated. Psychiatric symptoms and aspects of social functioning, including reported social self-efficacy and performance on social skills role-plays, were assessed before and after SST participation. Results: Preliminary data demonstrate improvements in both self-report and performance-based measures of social functioning after SST participation. Conclusions and Implications for Practice: These findings, though preliminary, support additional, larger-scale investigations of this SST among young adults with psychosis. Further, multidisciplinary collaborations are valuable in providing specialized care for young adults with psychosis who are receiving inpatient psychiatric care.

RESUMEN

INTRODUCTION: Individuals with psychotic-spectrum disorders may smoke due to the ameliorating effect of nicotine on the cognitive deficits that accompany these illnesses. Metacognitive remediation therapy (MCR) has been shown to produce improvements in cognitive functioning among individuals with psychotic-spectrum disorders and provides a foundation for a novel smoking cessation intervention for this population. AIMS: To complete an open investigation of pharmacotherapy and a modified version of MCR [MCR to Quit (MCR-Q)] in promoting smoking cessation among individuals with psychotic-spectrum disorders. METHODS: Forty-nine individuals with a psychotic-spectrum disorder and who currently smoke cigarettes participated in MCR-Q while also receiving evidence-based smoking cessation pharmacotherapy. Tobacco use was assessed as follows: (i) prior to MCR-Q, (ii) immediately after completing MCR-Q, and (iii) six weeks after completion of MCR-Q. RESULTS: /Findings. During participation in MCR-Q, nearly 80% of participants made a 24-hour quit attempt. Following the completion of MCR-Q, participants experienced reductions in level of nicotine dependency and exhaled carbon monoxide, with reductions in nicotine dependency sustained six weeks after completion of MCR-Q. Over the course of their participation in MCR-Q, participants reported strong therapeutic alliance with their MCR-Q therapist and high levels of intrinsic motivation with regard to completing MCR-Q exercises. CONCLUSIONS: The results from the current study suggest cautious optimism with regard to the use of MCR-Q in combination with medication for individuals with psychotic-spectrum disorders who want to quit smoking.

RESUMEN

INTRODUCTION: In October 2018, the Substance Abuse and Mental Health Services Administration funded 21 sites throughout the USA to develop, implement and evaluate specialised care programmes for individuals at clinical high risk for developing a psychotic disorder (CHR-P). Per the funding requirements, such programmes were required to provide 'step-based care'-a model in which individuals are initially provided with low-intensity, non-psychosis-specific and more benign (ie, least side effects) interventions and only progress onto higher-intensity, psychosis-specific interventions with a greater risk of more severe side effects should they not meet a priori criteria for clinical response to such lower-intensity interventions. Here, we outline the evaluation component of the step-based care programme for individuals at CHR-P at The Ohio State University Early Psychosis Intervention Center (EPICENTER). METHODS AND ANALYSES: The EPICENTER CHR-P programme provides a step-based care model comprising psychotherapy, medication management, family support/education, peer support and vocational/educational support. All participants who opt to receive care at the EPICENTER will complete a standardised assessment battery as part of usual care. This battery will be administered on enrolment and will be re-administered at 6-month intervals throughout individuals' participation in EPICENTER clinical services. Participants will have the opportunity to allow for data from these usual care assessments to be used as part of an evaluation project for this new clinical service. The primary outcome for this evaluation project is time to remission of symptomatic and functional deficits commonly experienced by individuals at CHR-P. Participants will also have the opportunity to participate in a supplemental research project designed to further evaluate treatment outcomes and patient characteristics among individuals participating in EPICENTER clinical services. ETHICS AND DISSEMINATION: This project was approved by The Ohio State University Institutional Review Board. Results from this project will be disseminated through publications and presentations. TRIAL REGISTRATION NUMBER: NCT03970005; Pre-results.

RESUMEN

AIM: Self-determination theory (SDT) has demonstrated that human well-being is associated with the satisfaction of three basic psychological needs (ie, autonomy, competence and relatedness)-with more recent research highlighting the applicability of SDT to individuals with first-episode psychosis (FEP). These findings suggest that satisfaction of basic psychological need may be an important treatment target for specialized clinical programs for FEP. METHODS: We examined the effects of participation in specialized, multi-component care for FEP on basic psychological need satisfaction. RESULTS: After 6 months of treatment, individuals with FEP experienced gains in autonomy and relatedness and a near significant improvement in competence. CONCLUSIONS: Although our results should be interpreted cautiously given the uncontrolled study design and small sample size, our data suggest that the benefits of participation in comprehensive, early intervention for psychotic disorders may include increased satisfaction of basic psychological needs.
