RESUMEN

Given the chronic and deleterious course of serious mental illness (SMI; schizophrenia and bipolar disorder), significant efforts have been undertaken to improve prediction of SMI and provide treatment for adolescents in the early, putatively prodromal stage of these illnesses. While risk assessments and disorder-specific treatments for adolescents at risk for SMI have shown some efficacy, significant issues remain around disorder-specific treatments for these youth. There is substantial heterogeneity of psychopathology within adolescents at high risk for SMI that leads to many false-positives and varying diagnostic outcomes. As a result, initial treatment focusing on broad symptoms and skills has been proposed in place of disorder-specific treatments. We discuss the rationale for providing an already-developed and empirically supported transdiagnostic treatment for emotional disorders (termed the Unified Protocol) as a first-line staging of treatment for adolescents experiencing early SMI symptoms. Additionally, we outline the open trial we are piloting using this transdiagnostic treatment in adolescents between the ages of 13 - 17 who have begun experiencing distressing yet subsyndromal psychosis or bipolar mood symptoms. Preliminary findings suggest feasibility and acceptability as well as initial efficacy in improving psychiatric symptoms, quality of life, and difficulties regulating emotions. We also present case studies from our open trial. A unified, cognitive-behavioral treatment for early presentations of SMI has important clinical and public health benefits, including streamlining treatment and providing broad skills that are applicable to a wide range of psychopathology.

RESUMEN

The developmental course of daily functioning prior to first psychosis-onset remains poorly understood. This study explored age-related periods of change in social and role functioning. The longitudinal study included youth (aged 12-23, mean follow-up years = 1.19) at clinical high risk (CHR) for psychosis (converters [CHR-C], n = 83; nonconverters [CHR-NC], n = 275) and a healthy control group (n = 164). Mixed-model analyses were performed to determine age-related differences in social and role functioning. We limited our analyses to functioning before psychosis conversion; thus, data of CHR-C participants gathered after psychosis onset were excluded. In controls, social and role functioning improved over time. From at least age 12, functioning in CHR was poorer than in controls, and this lag persisted over time. Between ages 15 and 18, social functioning in CHR-C stagnated and diverged from that of CHR-NC, who continued to improve (p = .001). Subsequently, CHR-C lagged behind in improvement between ages 21 and 23, further distinguishing them from CHR-NC (p < .001). A similar period of stagnation was apparent for role functioning, but to a lesser extent (p = .007). The results remained consistent when we accounted for the time to conversion. Our findings suggest that CHR-C start lagging behind CHR-NC in social and role functioning in adolescence, followed by a period of further stagnation in adulthood.

RESUMEN

AIM: There is limited research on the effects of sociodemographic and socioeconomic factors on treatment outcomes in youth at clinical high risk for psychosis (CHRp). This study examined sociodemographic factors that may affect functional outcomes within this population. Specifically, we investigated the influence of race/ethnicity (dichotomized as non-Hispanic whites [NHW] vs. people of colour [POC]), socioeconomic status (SES; operationalized as parental years of education), and their interaction on change in psychosocial functioning and symptoms over 6 months in a randomized trial of family-focused therapy. METHODS: CHRp youth (N = 128) participated in a randomized trial of family therapy (18 sessions of family therapy vs. 3 sessions of family psychoeducation). Sixty-four participants who self-identified as POC and 64 self-identified NHW participants completed baseline and 6-month follow-up measures of positive and negative symptoms and psychosocial (global, role, and social) functioning. Multiple regression models were conducted to test the main effect of race/ethnicity on changes in positive and negative symptoms and functioning, and whether this effect was moderated by parental education. RESULTS: There was a significant interaction between race/ethnicity and parental education, such that higher parental education was associated with greater improvement in global functioning in NHW participants, but there was no relationship between parental education and global functioning in POC. Additionally, higher parental education was associated with a decrease in negative symptoms in NHW participants but not in POC. There were no significant effects of race/ethnicity or parental education on positive symptoms, nor on social or role functioning. CONCLUSIONS: Clinicians may consider tailoring psychosocial treatments according to the needs of diverse families who vary in sociodemographic factors such as educational attainment and race/ethnicity.

RESUMEN

Youths at clinical high risk (CHR) for psychosis typically exhibit significant social dysfunction. However, the specific social behaviors associated with psychosis risk have not been well characterized. We administer the Social Responsiveness Scale (SRS), a measure of autistic traits that examines reciprocal social behavior, to the parents of 117 adolescents (61 CHR individuals, 20 age-matched adolescents with a psychotic disorder [AOP], and 36 healthy controls) participating in a longitudinal study of psychosis risk. AOP and CHR individuals have significantly elevated SRS scores relative to healthy controls, indicating more severe social deficits. Mean scores for AOP and CHR youths are typical of scores obtained in individuals with high functioning autism (Constantino & Gruber, 2005). SRS scores are significantly associated with concurrent real-world social functioning in both clinical groups. Finally, baseline SRS scores significantly predict social functioning at follow-up (an average of 7.2 months later) in CHR individuals, over and above baseline social functioning measures (p < .009). These findings provide novel information regarding impairments in domains critical for adolescent social development, because CHR individuals and those with overt psychosis show marked deficits in reciprocal social behavior. Further, the SRS predicts subsequent real-world social functioning in CHR youth, suggesting that this measure may be useful for identifying targets of treatment in psychosocial interventions.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Background: Elevated rates of alcohol, tobacco, and cannabis use are observed in both patients with psychotic disorders and individuals at clinical high risk for psychosis (CHR-P), and strong genetic associations exist between substance use disorders and schizophrenia. While individuals with 22q11.2 deletion syndrome (22qDel) are at increased genetic risk for psychosis, initial evidence suggests that they have strikingly low rates of substance use. In the current study, we aimed to directly compare substance use patterns and their neurobehavioral correlates in genetic and clinical high-risk cohorts. Methods: Data on substance use frequency and severity, clinical symptoms, and neurobehavioral measures were collected at baseline and at 12-month follow-up visits in two prospective longitudinal cohorts: participants included 89 22qDel carriers and 65 age and sex-matched typically developing (TD) controls (40.67% male, Mage = 19.26 ± 7.84 years) and 1,288 CHR-P youth and 371 matched TD controls from the North American Prodrome Longitudinal Study-2 and 3 (55.74% male; Mage = 18.71 ± 4.27 years). Data were analyzed both cross-sectionally and longitudinally using linear mixed effects models. Results: Controlling for age, sex, and site, CHR-P individuals had significantly elevated rates of tobacco, alcohol, and cannabis use relative to TD controls, whereas 22qDel had significantly lower rates. Increased substance use in CHR-P individuals was associated with increased psychosis symptom severity, dysphoric mood, social functioning, and IQ, while higher social anhedonia was associated with lower substance use across all domains at baseline. These patterns persisted when we investigated these relationships longitudinally over one-year. CHR-P youth exhibited significantly increased positive psychosis symptoms, dysphoric mood, social functioning, social anhedonia, and IQ compared to 22qDel carriers, and lower rates of autism spectrum disorder (ASD) compared to 22qDel carriers, both at baseline and at 1 year follow-up. Conclusion: Individuals at genetic and CHR-P have strikingly different patterns of substance use. Factors such as increased neurodevelopmental symptoms (lower IQ, higher rates of ASD) and poorer social functioning in 22qDel may help explain this distinction from substance use patterns observed in CHR-P individuals.

RESUMEN

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.

RESUMEN

INTRODUCTION: Disturbed sleep is a common feature of psychotic disorders that is also present in the clinical high risk (CHR) state. Evidence suggests a potential role of sleep disturbance in symptom progression, yet the interrelationship between sleep and CHR symptoms remains to be determined. To address this knowledge gap, we examined the association between disturbed sleep and CHR symptoms over time. METHODS: Data were obtained from the North American Prodrome Longitudinal Study (NAPLS)-3 consortium, including 688 CHR individuals and 94 controls (mean age 18.25, 46% female) for whom sleep was tracked prospectively for 8 months. We used Cox regression analyses to investigate whether sleep disturbances predicted conversion to psychosis up to >2 years later. With regressions and cross-lagged panel models, we analyzed longitudinal and bidirectional associations between sleep (the Pittsburgh Sleep Quality Index in conjunction with additional sleep items) and CHR symptoms. We also investigated the independent contribution of individual sleep characteristics on CHR symptom domains separately and explored whether cognitive impairments, stress, depression, and psychotropic medication affected the associations. RESULTS: Disturbed sleep at baseline did not predict conversion to psychosis. However, sleep disturbance was strongly correlated with heightened CHR symptoms over time. Depression accounted for half of the association between sleep and symptoms. Importantly, sleep was a significant predictor of CHR symptoms but not vice versa, although bidirectional effect sizes were similar. DISCUSSION: The critical role of sleep disturbance in CHR symptom changes suggests that sleep may be a promising intervention target to moderate outcome in the CHR state.

RESUMEN

AIMS: Young people with attenuated psychotic symptoms (APS), brief intermittent psychosis, and/or genetic risk and functional deterioration are at high risk for developing psychotic disorders. In a prior trial, family-focused therapy for clinical high risk youth (FFT-CHR) was more effective than brief psychoeducation in reducing APS severity over 6 months. This 7-site trial will compare the efficacy of FFT-CHR to a psychoeducational and supportive intervention (enhanced care) on APS and social functioning in CHR individuals over 18 months. METHODS: Participants (N = 220, ages 13-25 years) with a CHR syndrome will be randomly assigned to FFT-CHR (18 1-h sessions of family psychoeducation and communication/problem-solving skills training) or enhanced care (3 1-h family psychoeducational sessions followed by 5 individual support sessions), both given over 6 months. Participants will rate their weekly progress during treatment using a mobile-enhanced online platform. Family communication will be assessed in a laboratory interactional task at baseline and post-treatment. Independent evaluators will assess APS (primary outcome) and psychosocial functioning (secondary outcome) every 6 months over 18 months. RESULTS: We hypothesize that, compared to enhanced care, FFT-CHR will be associated with greater improvements in APS and psychosocial functioning over 18 months. Secondarily, improvements in family communication over 6 months will mediate the relationship between treatment condition and primary and secondary outcomes over 18 months. The effects of FFT-CHR are predicted to be greater in individuals with higher baseline risk for psychosis conversion. CONCLUSIONS: Results of the trial will inform treatment guidelines for individuals at high risk for psychosis.

RESUMEN

BACKGROUND: 22q11.2 deletion syndrome (22q11DS) is a common recurrent neurogenetic condition associated with elevated risk for developmental neuropsychiatric disorders and intellectual disability. Children and adults with 22q11DS often exhibit marked social impairment as well as neurocognitive deficits, and have elevated rates of both autism spectrum disorder (ASD) and psychosis. However, the relationship between the basic processes of social cognition and cognitive ability has not been well studied in 22q11DS. Here, we examined differences in social cognition in 22q11DS, relative to multiple groups of idiopathic neuropsychiatric disorders, and typically developing healthy controls (HC). Additionally, we examined differences in intellectual functioning and its relationship to social cognitive abilities. Finally, we examined the relationship between social cognitive abilities and real-world social behavior. METHODS: We examined social cognition and intellectual functioning in 273 participants (mean age = 17.74 ± 5.18% female = 44.3%): 50 with 22q11DS, 49 youth with first episode psychosis (FEP), 48 at clinical high-risk (CHR) for psychosis, 24 participants with ASD, and 102 HC. Social cognition was assessed using The Awareness of Social Inference Test (TASIT), while reciprocal social behavior was assessed via parent/caregiver ratings on the Social Responsiveness Scale (SRS). Participants were also administered the Wechsler Abbreviated Scale of Intelligence, 2nd edition (WASI-II) to assess intellectual functioning. RESULTS: The 22q11DS group exhibited significantly lower social cognitive abilities compared to CHR, FEP, and HC groups after controlling for intellectual functioning, but not in comparison to the ASD group. Significant positive correlations were found between social cognition, as measured by the TASIT and IQ across groups. In contrast, no significant relationships were found between TASIT and real-world social behavior (SRS) for any group. CONCLUSIONS: Our findings indicate social cognitive deficits are more prominent in 22q11DS than idiopathic neuropsychiatric conditions across the age range, even after adjusting for global intellectual function. These results contribute to our understanding of the intellectual and social vulnerabilities of 22q11DS in comparison to idiopathic neuropsychiatric disorders. Our findings of robust associations between intellectual ability and social cognition emphasizes the importance of accounting for neurocognitive deficits in social skills interventions and tailoring these existing treatment models for 22q11DS and other populations with intellectual impairment.

RESUMEN

This study prospectively examined the relationship between social problem solving behavior exhibited by youths at ultra-high risk for psychosis (UHR) and with recent onset psychotic symptoms and their parents during problem solving discussions, and youths' symptoms and social functioning six months later. Twenty-seven adolescents were administered the Structured Interview for Prodromal Syndromes and the Strauss-Carpenter Social Contact Scale at baseline and follow-up assessment. Primary caregivers participated with youth in a ten minute discussion that was videotaped, transcribed, and coded for how skillful participants were in defining problems, generating solutions, and reaching resolution, as well as how constructive and/or conflictual they were during the interaction. Controlling for social functioning at baseline, adolescents' skillful problem solving and constructive communication, and parents' constructive communication, were associated with youths' enhanced social functioning six months later. Controlling for symptom severity at baseline, we found that there was a positive association between adolescents' conflictual communications at baseline and an increase in positive symptoms six months later. Taken together, findings from this study provide support for further research into the possibility that specific family interventions, such as problem solving and communication skills training, may improve the functional prognosis of at-risk youth, especially in terms of their social functioning.

RESUMEN

OBJECTIVE: This study evaluates longitudinal neuropsychological performance and its association with clinical symptomatology and psychosocial outcome in individuals identified as ultra high risk (UHR) for psychosis. METHODS: Thirty-five UHR individuals completed neurocognitive, clinical, and social/role functioning assessments at baseline and, on average, 8.3 months later. RESULTS: UHR subjects showed significant cognitive deficits at baseline and 2 distinct profiles of cognitive change over time. On average, 50% demonstrated improvement in social and role functioning over the follow-up period, while the other half showed either stability or decline in functioning. Functional improvement was associated with improved processing speed and visual memory, as well as improvement in clinical symptoms over the follow-up period. In contrast, patients who did not improve functionally showed stable clinical symptoms and cognitive performance over time. CONCLUSIONS: Although the degree of neurocognitive deficit at baseline in UHR patients does not predict psychosocial outcome, the course of neurocognitive change over the first 8 months of follow-up does differentiate patients with good and poor functional outcomes.

RESUMEN

INTRODUCTION: Research on prediction and prevention of schizophrenia has increasingly focused on prodromal (prepsychosis) social and role dysfunction as developmentally early, stable, and treatment-resistant illness components. In this report, 2 new measures, Global Functioning: Social and Global Functioning: Role, are presented, along with preliminary findings about psychometric properties and course of social and role (academic/work) functioning in the prodromal phase of psychosis. METHODS: Subjects included 69 participants from the Recognition and Prevention program and 52 from the Center for the Assessment and Prevention of Prodromal States. Ages ranged from 12 to 29 years, and all met criteria for Attenuated Positive Symptom syndrome. Retrospective (past year) and baseline data are reported for all 121 prodromal subjects and for 44 normal controls (NCs). Prospective follow-up data are reported for a subsample of patients reevaluated at both 6 and 12 months (N = 44). RESULTS: For both scales, interrater reliability was high, and preliminary data supported construct validity. Relative to NCs, prodromal individuals displayed impaired social and role functioning at baseline. Analyses of change over time indicated that role functioning declined over the year before ascertainment and improved over 12-month follow-up, presumably with treatment. Social impairment, by contrast, was constant across time and predicted later psychosis (P = .002). DISCUSSION: Using 2 new global measures, social functioning was found to be a stable trait, unchanged by treatment, with considerable potential to be a marker of schizophrenia. Role functioning, by contrast, may be a more direct barometer of clinical change and may be responsive to treatment and environmental change.

RESUMEN

Individuals with schizophrenia (SZ) consistently show deficits in spatial working memory (WM) and associated atypical patterns of neural activity within key WM regions, including the dorsolateral prefrontal cortex (dlPFC) and parietal cortices. However, little research has focused on adolescent psychosis (AP) and potential age-associated disruptions of WM circuitry that may occur in youth with this severe form of illness. Here we utilized each subject's individual spatial WM capacity to investigate task-based neural dysfunction in 17 patients with AP (16.58 ± 2.60 years old) as compared to 17 typically developing, demographically comparable adolescents (18.07 ± 3.26 years old). AP patients showed lower behavioral performance at higher WM loads and lower overall WM capacity compared to healthy controls. Whole-brain activation analyses revealed greater bilateral precentral and right postcentral activity in controls relative to AP patients, when controlling for individual WM capacity. Seed-based psychophysiological interaction (PPI) analyses revealed significantly greater co-activation between the left dlPFC and left frontal pole in controls relative to AP patients. Significant group-by-age interactions were observed in both whole-brain and PPI analyses, with AP patients showing atypically greater neural activity and stronger coupling between WM task activated brain regions as a function of increasing age. Additionally, AP patients demonstrated positive relationships between right dlPFC neural activity and task performance, but unlike healthy controls, failed to show associations between neural activity and out-of-scanner neurocognitive performance. Collectively, these findings are consistent with atypical WM-related functioning and disrupted developmental processes in youth with AP.

RESUMEN

AIM: Little is known about the role of expressed emotion (EE) in early symptom expression in individuals at clinical high risk (CHR) for psychosis. In patients with established schizophrenia, the effects of EE on clinical outcomes have purportedly varied across racial/ethnic groups, but this has not yet been investigated among CHR patients. Furthermore, studies have traditionally focused upon caregiver levels of EE via interview-based ratings, whereas the literature on patient perceptions of caregiver EE on psychosis symptoms is relatively limited. METHODS: Linear regression models were conducted to examine the impact of criticism and perceived warmth in the family environment, from the CHR patient's perspective, on positive and negative symptom expression in non-Latino white (NLW; n = 38) and Latino (n = 11) adolescents and young adults at CHR for developing psychosis. RESULTS: Analyses examining the sample as a whole demonstrated that perceived levels of maternal criticism were negatively associated with negative CHR symptomatology. Additional analyses indicated that race/ethnicity moderated the relationship between criticism/warmth and clinical symptomatology. We found evidence of a contrasting role of patient perceived criticism and warmth depending upon the patient's race/ethnicity. CONCLUSION: Family processes shown to impact the course of schizophrenia among NLWs may function differently among Latino than NLW patients. These findings have important implications for the development of culturally appropriate interventions and may aid efforts to improve the effectiveness of mental health services for diverse adolescents and young adults at CHR for psychosis. Given the small sample size of this study, analyses should be replicated in a larger study before more definitive conclusions can be made.

RESUMEN

AIM: There is a wealth of evidence suggesting that patients with schizophrenia tend to respond to life stressors using less effective coping skills, which are in turn related to poor outcome. However, the contribution of coping strategies to outcome in youth at clinical high risk (CHR) for developing psychosis has not been investigated. METHODS: This longitudinal study followed CHR youth over a 12-month period, using the Brief COPE questionnaire. CHR subjects (n = 88) were compared at baseline with a healthy control sample (n = 53), and then mixed models were used to explore the relationship of coping strategies to clinical and psychosocial outcomes in CHR subjects over time (n = 102). RESULTS: Cross-sectional analyses revealed that, in comparison with healthy controls, CHR youth reported using more maladaptive coping strategies (P < 0.001) and fewer adaptive coping strategies (P < 0.01). Longitudinal analyses within the CHR group showed significant decreases in maladaptive coping and symptom severity over time, with corresponding improvements in social and role functioning. Adaptive coping was associated with better concurrent social functioning and less severe symptomatology (both P < 0.001). Over time, more maladaptive coping was associated with more severe positive and negative symptoms (both P < 0.005). CONCLUSIONS: Youth at risk for psychosis report using fewer adaptive and more maladaptive coping strategies relative to healthy controls. Over 1-year follow-up, more adaptive coping styles are associated with less severe clinical symptomatology and better social functioning. These findings suggest that teaching adaptive coping styles may be an important target for intervention in youth at high risk for psychosis.

RESUMEN

OBJECTIVE: This study investigated whether family focused therapy (FFT-CHR), an 18-session intervention that consisted of psychoeducation and training in communication and problem solving, brought about greater improvements in family communication than enhanced care (EC), a 3-session psychoeducational intervention, among individuals at clinical high risk for developing psychosis. METHOD: This study was conducted within a randomized controlled trial across 8 sites. We examined 10-min problem-solving discussions at baseline and 6-month reassessment among 66 adolescents and young adults and their parents. Trained coders who were blind to treatment and time of assessment achieved high levels of interrater reliability when evaluating family discussions on categories of calm-constructive and critical-conflictual behavior. RESULTS: Individuals at high risk and their family members who participated in FFT-CHR demonstrated greater improvement from baseline to 6-month reassessment in constructive communication and decreases in conflictual behaviors during family interactions than those in EC. Participants in FFT-CHR showed greater increases from baseline to 6 months in active listening and calm communication and greater decreases in irritability and anger, complaints and criticism, and off-task comments compared to participants in EC. These changes occurred equally in high-risk participants and their family members. CONCLUSIONS: A 6-month family skills training treatment can bring about significant improvement in family communication among individuals at high risk for psychosis and their parents. Future studies should examine the association between enhancements in family communication and reduced risk for the onset of psychosis among individuals at high risk.

RESUMEN

OBJECTIVE: Longitudinal studies have begun to clarify the phenotypic characteristics of adolescents and young adults at clinical high risk for psychosis. This 8-site randomized trial examined whether a 6-month program of family psychoeducation was effective in reducing the severity of attenuated positive and negative psychotic symptoms and enhancing functioning among individuals at high risk. METHOD: Adolescents and young adults (mean age 17.4 ± 4.1 years) with attenuated positive psychotic symptoms, brief and intermittent psychosis, or genetic risk with functional deterioration were randomly assigned to 18 sessions of family-focused therapy for individuals at clinical high risk (FFT-CHR) in 6 months or 3 sessions of family psychoeducation (enhanced care [EC]). FFT-CHR included psychoeducation about early signs of psychosis, stress management, communication training, and problem-solving skills training, whereas EC focused on symptom prevention. Independent evaluators assessed participants at baseline and 6 months on positive and negative symptoms and social-role functioning. RESULTS: Of 129 participants, 102 (79.1%) were followed up at 6 months. Participants in FFT-CHR showed greater improvements in attenuated positive symptoms over 6 months than participants in EC (F1,97 = 5.49, p = .02). Negative symptoms improved independently of psychosocial treatments. Changes in psychosocial functioning depended on age: participants more than 19 years of age showed more role improvement in FFT-CHR, whereas participants between 16 and 19 years of age showed more role improvement in EC. The results were independent of concurrent pharmacotherapy. CONCLUSION: Interventions that focus on improving family relationships may have prophylactic efficacy in individuals at high risk for psychosis. Future studies should examine the specificity of effects of family intervention compared to individual therapy of the same duration and frequency.

RESUMEN

AIM: This article outlines the rationale for a family-focused psychoeducational intervention for individuals at risk for psychosis and explains the design of a randomized multisite trial to test its efficacy. METHODS: Adolescents and young adults that meet criteria for a psychosis risk syndrome at eight participating North American Prodromal Longitudinal Study sites are randomly assigned to a 6-month, 18-session family-focused treatment for prodromal youth or a 3-session psychoeducational enhanced care control intervention and followed over 1 year. RESULTS: The results will determine whether the use of a family intervention is able to significantly improve functional outcomes, decrease the severity of positive symptoms and possibly prevent the onset of full psychosis, compared with enhanced care alone. Levels of familial criticism at baseline are hypothesized to moderate responses to family intervention. Improvements in knowledge about symptoms, family communication and problem solving will be tested as mediators in the pathways between treatment assignment and clinical or psychosocial outcomes in high-risk youth. CONCLUSIONS: The ongoing trial evaluates whether a non-invasive psychosocial approach can significantly enhance functional outcomes and prevent the ultra high risk patients from developing psychosis. The results will provide an important stepping stone in the movement of the field from refining early detection strategies to developing efficacious preventative treatments.
