RESUMO

Objective: Family-focused therapy (FFT) is associated with enhanced outcomes in youth with bipolar and depressive disorders, but has not been evaluated in conjunction with mobile health tools. In symptomatic adolescents whose parents had histories of mood disorders, we examined whether the effects of telehealth-based FFT were augmented by mobile health apps that emphasized mood tracking and family coping skills. Method: Participants (aged 13-19 years) had active mood symptoms and a parent with major depressive or bipolar disorder. Participants received 12 sessions in 18 weeks of telehealth FFT, with random assignment to (1) a mobile app (MyCoachConnect, MCC) that enabled mood tracking, reviews of session content, and text reminders to practice mood management and family communication skills (FFT-MCC); or (2) a mobile app that enabled mood tracking only (FFT-Track). Independent evaluators assessed youth every 9 weeks over 6 months on depressive symptoms (primary outcome), anxiety, and psychosocial functioning. Results: Participants (N = 65; mean age 15.8 ± 1.6 years) significantly improved in depressive symptoms over 6 months (F1,170 = 45.02, p < .0001; ή2 = 0.21, 95% CI = 0.11-0.31), but there were no effects of treatment condition or treatment by time interactions on depression scores. When secondary outcome measures were considered, the subgroup of youth with bipolar spectrum disorders showed greater improvements in anxiety and global functioning in FFT-MCC compared with FFT-Track. Conclusion: Youth in the early stages of mood disorder may benefit from FFT enhanced by mobile health apps. Collaborations between researchers and information technologists on mobile app design and user experience may lead to increases in engagement among adolescents.

RESUMO

BACKGROUND: Since the COVID-19 pandemic, psychosocial therapies have been provided in varying formats, including remote, in-person, and hybrid services. It is unclear whether varying formats are similarly efficacious in improving psychiatric symptoms and functioning, lead to similar rates of treatment retention, and are equally acceptable to patients. This study compared youth with mood disorders and/or psychosis-risk syndromes who participated in a group cognitive behavioral therapy (CBT) in-person prior to COVID-19, to youth in the same treatment given remotely during the pandemic. METHODS: Adolescents ages 13-17 years participated in 9 sessions of group-based CBT given in-person (2018-2019) or remotely (2020-2021). Youth participants provided self-report ratings of psychiatric symptoms, psychosocial functioning, and emotional regulation at the study baseline and post-treatment and ratings of treatment satisfaction and burden at post-treatment. RESULTS: There were no differences between in-person and remote treatment improvements in psychiatric symptoms, psychosocial functioning or emotional regulation. However, youth in remote treatment had increased retention compared to youth who received treatment in person. Youth in the remote treatment reported similar levels of satisfaction but reported lower burden compared to those who received in-person treatment. LIMITATIONS: Participants were not randomized into remote or in-person treatment. Participants prior to COVID did not have the same frame of reference for alternative treatment delivery options as those during or post-COVID. CONCLUSIONS: Remote group treatment can provide similar levels of psychiatric benefit but less burden than in-person treatment for youth with mood disorders and/or psychosis-risk syndromes.

RESUMO

OBJECTIVES: There is substantial evidence that cognitive behavioral therapy (CBT) and mindfulness-based cognitive therapy (MBCT) improve symptoms and functioning in adults with mood and psychotic disorders. There has been little work directly comparing these treatments among adolescents with early-onset mood or psychosis symptoms. METHOD: We conducted a randomized controlled trial comparing remotely administered group CBT to group MBCT for adolescents (ages 13-17) with a mood disorder or attenuated psychosis symptoms. Adolescents attended nine sessions over 2 months; their parents attended parallel groups focused on the same skill practices. Participants were assessed for psychiatric symptoms and functioning at posttreatment and 3 months posttreatment. RESULTS: Sixty-six youth (Mage = 15.1 years, SD = 1.4; 44 females [66.7%]) initiated the trial (32 in CBT and 34 in MBCT), with 54 retained at posttreatment and 53 at the 3-month follow-up. The treatments were associated with comparable improvements in adolescents' mood, anxiety, attenuated psychosis symptoms, and psychosocial functioning over 5 months. CBT was associated with greater improvements than MBCT in emotion regulation and well-being during the posttreatment period. MBCT (compared to CBT) was associated with greater improvements in social functioning among adolescents with greater childhood adversity. Both treatments had comparable rates of retention, but youth and parents reported more satisfaction with CBT than MBCT. CONCLUSIONS: The beneficial effect of both treatments in a group telehealth format is encouraging. Due to our limited sample, future research should investigate whether adolescents' history of adversity and treatment preferences replicate as treatment moderators for youth with mood or psychosis symptoms.

RESUMO

BACKGROUND: We examined whether digital phenotyping of spontaneous speech, such as the use of specific word categories during speech samples, was associated with depressive symptoms in youth who were at familial and clinical risk for mood disorders. METHODS: Participants (ages 13-19) had active mood symptoms, mood instability, and at least one parent with bipolar or major depressive disorder. During a randomized trial of family-focused therapy, participants were instructed to make weekly calls to a central voice server and leave speech samples in response to automated prompts. We coded youths' speech samples with the Linguistic Inquiry and Word Count system and used machine learning to identify the combination of speech features that were most closely associated with the course of depressive symptoms over 18 weeks. RESULTS: A total of 253 speech samples were collected from 44 adolescents (mean age = 15.8 years; SD = 1.6) over 18 weeks. Speech containing affective processes, social processes, drives toward risk or reward, nonfluencies, and time orientation words were correlated with depressive symptoms at concurrent time periods (ps < 0.01). Machine learning analyses revealed that affective processes, nonfluencies, drives and risk words combined to most strongly predict changes in depressive symptoms over 18 weeks of treatment. LIMITATIONS: Study results were limited by the small sample and the exclusion of paralinguistic or contextual variables in analyzing speech samples. CONCLUSIONS: In youth at high risk for mood disorders, knowledge of speech patterns may inform prognoses during outpatient psychosocial treatment.

RESUMO

BACKGROUND: Although transdiagnostic forms of cognitive-behavioral therapy (CBT) have been evaluated in individuals with depressive and anxiety disorders, few studies have examined their suitability for more severe disorders, such as recurrent or persistent major depressive disorder, bipolar disorder, or psychotic spectrum disorders. This study examined the acceptability and initial efficacy of an app-enhanced Unified Protocol for Adolescents [UP-A] when including youth with more severe mood disorders or psychotic spectrum disorders. METHODS: We first adapted a mobile application (app), based on user-centered feedback from adolescents and their parents, to assist participants in reviewing session content, practicing skills learned in previous treatment sessions, and monitoring symptomatic progress. A total of 24 adolescents (M age = 15.2 years, SD = 1.6) with mood or psychotic spectrum disorders and their parents then participated in an open trial of the app-enhanced group treatment given over 9 weekly sessions. RESULTS: Adolescent participants and their parents rated the group treatment and mobile app as acceptable and useful. We observed significant improvements over the 9-week treatment in adolescents' depressive symptoms, attenuated psychotic symptoms, and global functioning. The frequency with which adolescents used the mobile app between sessions was positively related to symptomatic and functional gains. CONCLUSIONS: Initial findings suggest the acceptability and feasibility of a mobile app that enabled adolescent participants and their parents to review session content and practice treatment skills. Findings also indicated improvements in psychiatric and functional outcomes among the adolescent participants over the course of the app-enhanced treatment. Randomized clinical trials are needed to evaluate the efficacy of app-enhanced CBT in improving symptoms and functioning in adolescents with mood or psychotic spectrum disorders.

RESUMO

Research shows promise for cognitive interventions for children diagnosed with brain tumors. Interventions have been delivered approximately 5 years postdiagnosis on average, yet recent evidence shows cognitive deficits may appear near diagnosis. The present study assessed the feasibility and initial effects of working memory training in children with brain tumors delivered soon after diagnosis and followed 2 years postdiagnosis. Children completed baseline assessments 10 months postdiagnosis and were randomized to complete adaptive or nonadaptive (i.e., control) Cogmed Working Memory Training. Children were administered the WISC-IV Working Memory Index (WMI) and NIH Toolbox Cognitive Battery (NTCB), and parents completed attentional and executive function measures at four time points. On average, participants completed half of prescribed Cogmed sessions. Retention for the three follow-up assessments proved difficult. For both Cogmed groups, WMI and NTCB scores significantly improved immediately postintervention compared to baseline scores. Significant differences were not maintained at the remaining follow-ups. There was preliminary evidence for improved executive function at the final follow-up on parent-reported measures. Working memory training closer to diagnosis proved difficult, though results suggest evidence of cognitive improvement. Future studies should continue to examine potentially efficacious interventions for children with brain tumors and optimal delivery windows to maximize impact.

RESUMO

Objective: Youth coping is consistently associated with risk and resilience for youth internalizing psychopathology. Integrating questionnaire and experimental methods is an important next step in understanding how youth develop, learn, and implement these skills and to identify possible neurobiological mechanisms that underlie these processes. The current study aims to explore associations among youth self-reported and laboratory-based measures of two methods of coping (distraction and reappraisal). Further, the current study aims to examine associations among neural correlates of distraction and reappraisal with symptoms of anxiety and depression in youth.Methods: Youth (N = 69; M = 12.24, SD = 1.83; 52.9% female) completed self-report measures of secondary control coping (RSQ) and symptoms of anxiety (SCARED) and depression (CES-D) and a laboratory coping task. While completing the task, prefrontal hemodynamic changes were measured using functional near-infrared spectroscopy (fNIRS).Results: Neural activation during reappraisal was significantly negatively correlated with youth anxiety symptoms, and both neural activation and self-reported coping were significant independent predictors of anxiety. Youth self-reported coping was not associated with neural activation during reappraisal or distraction.Conclusions: The measurement of possible neural markers of risk and resilience in youth is an important area of continued research. Identification of possible mechanisms of change related to anxiety and depression in youth may inform targets of intervention.

RESUMO

Working memory deficits are observed in the vast majority of individuals diagnosed with schizophrenia and those at risk for the disorder. Working memory impairments are present during the prodromal stage and persist throughout the course of schizophrenia. Given the importance of cognition in functional outcome, working memory deficits are an important therapeutic target for schizophrenia. This chapter examines mechanisms underlying working memory deficits in schizophrenia, focusing on the roles of perception and attention in the encoding process. Lastly, we present a comprehensive discussion of neural oscillation and internal noise in the context of the etiology of working memory deficits in schizophrenia and introduce noninvasive treatment strategies that could improve encoding processes.

RESUMO

Past research indicates that spontaneous mimicry facilitates the decoding of others' emotions, leading to enhanced social perception and interpersonal rapport. Individuals with schizophrenia (SZ) show consistent deficits in emotion recognition and expression associated with poor social functioning. Given the prominence of blunted affect in schizophrenia, it is possible that spontaneous facial mimicry may also be impaired. However, studies assessing automatic facial mimicry in schizophrenia have yielded mixed results. It is therefore unknown whether emotion recognition deficits and impaired automatic facial mimicry are related in schizophrenia. SZ and demographically matched controls (CO) participated in a dynamic emotion recognition task. Electromyographic activity in muscles responsible for producing facial expressions was recorded during the task to assess spontaneous facial mimicry. SZ showed deficits in emotion identification compared to CO, but there was no group difference in the predictive power of spontaneous facial mimicry for avatar's expressed emotion. In CO, facial mimicry supported accurate emotion recognition, but it was decoupled in SZ. The finding of intact facial mimicry in SZ bears important clinical implications. For instance, clinicians might be able to improve the social functioning of patients by teaching them to pair specific patterns of facial muscle activation with distinct emotion words.

RESUMO

Social impairment is a core feature of schizophrenia that presents a major barrier toward recovery. Some of the psychotic symptoms are partly ameliorated by medication but the route to recovery is hampered by social impairments. Since existing social skills interventions tend to suffer from lack of availability, high-burden and low adherence, there is a dire need for an effective, alternative strategy. The present study examined the feasibility and acceptability of Multimodal Adaptive Social Intervention in Virtual Reality (MASI-VR) for improving social functioning and clinical outcomes in schizophrenia. Out of eighteen patients with schizophrenia who enrolled, seventeen participants completed the pre-treatment assessment and 10 sessions of MASI-VR, but one patient did not complete the post-treatment assessments. Therefore, the complete training plus pre- and post-treatment assessment data are available from sixteen participants. Clinical ratings of symptom severity were obtained at pre- and post-training. Retention rates were very high and training was rated as extremely satisfactory for the majority of participants. Participants exhibited a significant reduction in overall clinical symptoms, especially negative symptoms following 10 sessions of MASI-VR. These preliminary results support the feasibility and acceptability of a novel virtual reality social skills training program for individuals with schizophrenia.

RESUMO

Emotion recognition impairment is a core feature of schizophrenia (SZ), present throughout all stages of this condition, and leads to poor social outcome. However, the underlying mechanisms that give rise to such deficits have not been elucidated and hence, it has been difficult to develop precisely targeted interventions. Evidence supports the use of methods designed to modify patterns of visual attention in individuals with SZ in order to effect meaningful improvements in social cognition. To date, however, attention-shaping systems have not fully utilized available technology (e.g., eye tracking) to achieve this goal. The current work consisted of the design and feasibility testing of a novel gaze-sensitive social skills intervention system called MASI-VR. Adults from an outpatient clinic with confirmed SZ diagnosis (n=10) and a comparison sample of neurotypical participants (n=10) were evaluated on measures of emotion recognition and visual attention at baseline assessment, and a pilot test of the intervention system was evaluated on the SZ sample following five training sessions over three weeks. Consistent with the literature, participants in the SZ group demonstrated lower recognition of faces showing medium intensity fear, spent more time deliberating about presented emotions, and had fewer fixations in comparison to neurotypical peers. Furthermore, participants in the SZ group showed significant improvement in the recognition of fearful faces post-training. Preliminary evidence supports the feasibility of a gaze-sensitive paradigm for use in assessment and training of emotion recognition and social attention in individuals with SZ, thus warranting further evaluation of the novel intervention.

RESUMO

Neurocognitive problems in childhood survivors of brain tumors are well documented. Further, research has shown that problems in cognitive functioning may be associated with impairment in the use of complex strategies needed to cope with stress, including secondary control coping strategies (e.g., acceptance and cognitive reappraisal) which have been associated with fewer adjustment problems. The present study measured cognitive function, coping strategies, and adjustment in children ages 6-16 years at the time of brain tumor diagnosis and at two follow-up time-points up to 1 year post-diagnosis. In a prospective design, working memory was assessed in a total of 29 pediatric brain tumor patients prior to undergoing surgery, child self-reported coping was assessed at 6 months post-diagnosis, and parent-reported child adjustment was assessed at 12 months post-diagnosis. Significant correlations were found between working memory difficulties and secondary control coping. Secondary control coping was also negatively correlated with child attention and total problems. Regression analyses did not support secondary control coping mediating the association between working memory difficulties and child attention or total problems. These findings represent the first longitudinal assessment of the association between working memory, coping, and adjustment across the first year of a child's brain tumor diagnosis and suggest a possible role for early interventions addressing both working memory difficulties and coping in children with brain tumors.

RESUMO

Excitation-inhibition balance (E/I balance) is a fundamental property of cortical microcircuitry. Disruption of E/I balance in prefrontal cortex is hypothesized to underlie cognitive deficits observed in neuropsychiatric illnesses such as schizophrenia. To elucidate the link between these phenomena, we incorporated synaptic disinhibition, via N-methyl-D-aspartate receptor perturbation on interneurons, into a network model of spatial working memory (WM). At the neural level, disinhibition broadens the tuning of WM-related, stimulus-selective persistent activity patterns. The model predicts that this change at the neural level leads to 2 primary behavioral deficits: 1) increased behavioral variability that degrades the precision of stored information and 2) decreased ability to filter out distractors during WM maintenance. We specifically tested the main model prediction, broadened WM representation under disinhibition, using behavioral data from human subjects performing a spatial WM task combined with ketamine infusion, a pharmacological model of schizophrenia hypothesized to induce disinhibition. Ketamine increased errors in a pattern predicted by the model. Finally, as proof-of-principle, we demonstrate that WM deteriorations in the model can be ameliorated by compensations that restore E/I balance. Our findings identify specific ways by which cortical disinhibition affects WM, suggesting new experimental designs for probing the brain mechanisms of WM deficits in schizophrenia.
