<h4>Objective</h4>Understanding the experience of individuals across stages of schizophrenia is important for development of services to promote recovery. As yet, little is known about the experience of individuals who exhibit prodromal symptoms of schizophrenia.<h4>Methods</h4>Audiotaped interviews were conducted with 27 participants of diverse racial-ethnic backgrounds who were at clinically high risk of psychosis (15 males and 12 females; mean age 21).

Project description:ImportanceAltered neurodevelopmental trajectories are thought to reflect heterogeneity in the pathophysiologic characteristics of schizophrenia, but whether neural indicators of these trajectories are associated with future psychosis is unclear.ObjectiveTo investigate distinct neuroanatomical markers that can differentiate aberrant neurodevelopmental trajectories among clinically high-risk (CHR) individuals.Design, setting, and participantsIn this prospective longitudinal multicenter study, a neuroanatomical-based age prediction model was developed using a supervised machine learning technique with T1-weighted magnetic resonance imaging scans of 953 healthy controls 3 to 21 years of age from the Pediatric Imaging, Neurocognition, and Genetics (PING) study and then applied to scans of 275 CHR individuals (including 39 who developed psychosis) and 109 healthy controls 12 to 21 years of age from the North American Prodrome Longitudinal Study 2 (NAPLS 2) for external validation and clinical application. Scans from NAPLS 2 were collected from January 15, 2010, to April 30, 2012.Main outcomes and measuresDiscrepancy between neuroanatomical-based predicted age (hereafter referred to as brain age) and chronological age.ResultsThe PING-derived model (460 females and 493 males; age range, 3-21 years) accurately estimated the chronological ages of the 109 healthy controls in the NAPLS 2 (43 females and 66 males; age range, 12-21 years), providing evidence of independent external validation. The 275 CHR individuals in the NAPLS 2 (111 females and 164 males; age range, 12-21 years) showed a significantly greater mean (SD) gap between model-predicted age and chronological age (0.64 [2.16] years) compared with healthy controls (P = .008). This outcome was significantly moderated by chronological age, with brain age systematically overestimating the ages of CHR individuals who developed psychosis at ages 12 to 17 years but not the brain ages of those aged 18 to 21 years. Greater brain age deviation was associated with a higher risk for developing psychosis (F = 3.70; P = .01) and a pattern of stably poor functioning over time, but only among younger CHR adolescents. Previously reported evidence of accelerated reduction in cortical thickness among CHR individuals who developed psychosis was found to apply only to those who were 18 years of age or older.Conclusions and relevanceThese results are consistent with the view that neuroanatomical markers of schizophrenia may help to explain some of the heterogeneity of this disorder, particularly with respect to early vs later age of onset of psychosis, with younger and older individuals having differing intercepts and trajectories in structural brain parameters as a function of age. The results also suggest that baseline neuroanatomical measures are likely to be useful in estimating onset of psychosis, especially (or only) among CHR individuals with an earlier age of onset of prodromal symptoms.

Project description:Background/objectivesPsychiatry lacks the objective clinical tests routinely used in other specializations. Novel computerized methods to characterize complex behaviors such as speech could be used to identify and predict psychiatric illness in individuals.AimsIn this proof-of-principle study, our aim was to test automated speech analyses combined with Machine Learning to predict later psychosis onset in youths at clinical high-risk (CHR) for psychosis.MethodsThirty-four CHR youths (11 females) had baseline interviews and were assessed quarterly for up to 2.5 years; five transitioned to psychosis. Using automated analysis, transcripts of interviews were evaluated for semantic and syntactic features predicting later psychosis onset. Speech features were fed into a convex hull classification algorithm with leave-one-subject-out cross-validation to assess their predictive value for psychosis outcome. The canonical correlation between the speech features and prodromal symptom ratings was computed.ResultsDerived speech features included a Latent Semantic Analysis measure of semantic coherence and two syntactic markers of speech complexity: maximum phrase length and use of determiners (e.g., which). These speech features predicted later psychosis development with 100% accuracy, outperforming classification from clinical interviews. Speech features were significantly correlated with prodromal symptoms.ConclusionsFindings support the utility of automated speech analysis to measure subtle, clinically relevant mental state changes in emergent psychosis. Recent developments in computer science, including natural language processing, could provide the foundation for future development of objective clinical tests for psychiatry.

Project description:Aberrant pauses are characteristic of schizophrenia and are robustly associated with its negative symptoms. Here, we found that pause behavior was associated with negative symptoms in individuals at clinical high risk (CHR) for psychosis, and with measures of syntactic complexity-phrase length and usage of determiners that introduce clauses-that we previously showed in this same CHR cohort to help comprise a classifier that predicted psychosis. These findings suggest a common impairment in discourse planning and verbal self-monitoring that affects both speech and language, and which is detected in clinical ratings of negative symptoms.

Project description:The Center for Interprofessional Training in Medicine at the Faculty of Medicine Carl Gustav Carus at the Technische Universität Dresden, Germany, has offered courses covering interprofessional material since the winter semester 2014/15. The unusual feature of these courses is that they are co-taught by peer tutors from medicine and nursing. This study investigates the subjective experiences of these tutors during the collaborative preparation and teaching of these tutorials with the aim of identifying the effects of equal participation in the perceptions and assessments of the other professional group.Semi-structured, guideline-based interviews were held with six randomly selected tutors. The interviews were analyzed using structuring content analysis.The results show that collaborative work led to reflection, mostly by the university student tutors, on the attitudes held. However, the co-tutors from each professional group were perceived to different degrees as being representative of those in their profession. Asked to master a shared assignment in a non-clinical context, the members of the different professional groups met on equal footing, even if the medical students had already gathered more teaching experience and thus mostly assumed a mentoring role over the course of working on and realizing the teaching units. The nursing tutors were primarily focused on their role as tutor. Both professional groups emphasized that prior to the collaboration they had an insufficient or no idea about the theoretical knowledge or practical skills of the other professional group. Overall, the project was rated as beneficial, and interprofessional education was endorsed.In the discussion, recommendations based on the insights are made for joint tutor training of both professional groups. According to these recommendations, harmonizing the teaching abilities of all tutors is essential to ensure equality during cooperation. Ideally, training programs should be attended together by medical and nursing students to emphasize their shared identity as "tutor".

Project description:Objectives(1) To capture the subjective experience of meningitis survivors during adolescence and adulthood and (2) To explore how they give meaning to this specific experience.DesignA qualitative study of in-depth interviews using interpretative phenomenological analysis.SettingsParticipants recruited through an association of persons affected by meningitis and their relatives.ParticipantsConvenience sample of nine participants (seven women and two men) between the ages of 18 to 48 years (mean=28.3, SD=11.4), who personally experienced meningitis.ResultsEight major themes and three main meaning-making processes in relation to the participants' experiences of meningitis were identified: (1) the ability to rely on the testimony of others, (2) the impossibility of meaning-making and (3) the possibility of post-traumatic growth. We detailed here five major themes, which appear critical to answering the objective of the study.ConclusionsThis study provides a unique insight into the first-hand experience of surviving meningitis. Findings highlighted factors characterising the disease experience, the psychological adjustment of meningitis survivors and their meaning-making processes. These findings are important for both research and clinical practice, demonstrating the importance of direct involvement of meningitis survivors in identifying key aspects of care, which include the critical role of relatives, and the importance of investigating the need for training among healthcare providers on how to diagnose meningitis.

Project description:ObjectivesTo compare the longitudinal clinical course of youths with bipolar disorder (BD) spectrum with lifetime (past, intake, and/or follow-up) psychosis (BDP+) to youths with BD without lifetime psychosis (BDP-). Also, to identify risk factors associated with increased risk of first onset of psychosis during prospective follow-up.MethodBipolar disorder youths (BDP+ = 137, BDP- = 233), aged 7-17 years old, were followed on average every 7 months for 11.7 years and were evaluated using standardized instruments. Data were analyzed using linear and generalized linear models for the full sample, as well as for youths who developed first period of psychosis (n = 55).ResultsAfter adjusting for confounders, BDP+ youths with one, and in particular ≥2 lifetime psychotic episodes, had higher rates and more severe mood and anxiety symptoms, higher rates of suicidality, psychiatric hospitalizations, and sexual/physical abuse, and poorer psychosocial functioning than BDP- youths. Even before the first onset of psychosis during follow-up, BDP+ youths showed more psychopathology and had more family history of psychiatric illness than those who never developed psychosis. First-onset psychosis was associated with low socioeconomic status (SES), living with one parent, bipolar disorder type one and type two, comorbid anxiety, history of hospitalizations, and family history of mania and suicidality.ConclusionBDP+ is associated with poor prognosis and worse clinical picture, even before the onset of psychosis, indicating the need for prompt identification and treatment of these youths. Studies aimed to treat acute symptoms of psychosis, as well as prevent the onset of psychosis, including risk factors amenable to change, are warranted.

Project description:Previous research studies regarding music therapy and severe mental illness have mainly adopted quantitative methodologies in order to study the effectiveness of music therapy interventions. Studies that have explored service users' experiences of participation in music therapy are small in number, and almost nonexistent in the field of psychosis. This study aimed to explore how mental health patients with a diagnosis of psychosis experienced participation in music therapy, in general, and more specifically how they experienced music therapy in relation to their current mental state and life situation. Nine inpatients with psychosis were interviewed using a semi-structured interview focusing on the participants' experiences of music therapy in individual sessions, groups, and performances. Through the use of interpretative phenomenological analysis, four super-ordinate themes central to the participants' experiences were found: freedom, contact, well-being, and symptom reduction. Based on the findings, mental health recovery, positive mental health, and agency are proposed as constituting a better framework for music therapy in mental healthcare than a primary focus on symptom remission and functional improvement.

Project description:Structural brain abnormalities have been amply demonstrated in schizophrenia. These include volume decrements in the perirhinal/entorhinal regions of the ventromedial temporal lobe, which comprise the primary olfactory cortex. Olfactory impairments, which are a hallmark of schizophrenia, precede the onset of illness, distinguish adolescents experiencing prodromal symptoms from healthy youths, and may predict the transition from the prodrome to frank psychosis. We therefore examined temporal lobe regional volumes in a large adolescent sample to determine if structural deficits in ventromedial temporal lobe areas were associated, not only with schizophrenia, but also with a heightened risk for psychosis. Seven temporal lobe regional volumes (amygdala [AM], hippocampus, inferior temporal gyrus, parahippocampal gyrus, superior temporal gyrus, temporal pole, and entorhinal cortex [EC]) were measured in 386 psychosis spectrum adolescents, 521 adolescents with other types of psychopathology, and 359 healthy adolescents from the Philadelphia Neurodevelopment Cohort. Total intracranial and left EC volumes, which were both smallest among the psychosis spectrum, were the only measures that distinguished all 3 groups. Left AM was also smaller in psychosis spectrum compared with healthy subjects. EC volume decrement was strongly correlated with impaired cognition and less robustly associated with heightened negative/disorganized symptoms. AM volume decrement correlated with positive symptoms (persecution/special abilities). Temporal lobe volumes classified psychosis spectrum youths with very high specificity but relatively low sensitivity. These MRI measures may therefore serve as important confirmatory biomarkers denoting a worrisome preclinical trajectory among at-risk youths, and the specific pattern of deficits may predict specific symptom profiles.

Project description:BackgroundDisturbances in trait emotions are a predominant feature in schizophrenia. However, less is known about (a) differences in trait emotion across phases of the illness such as the clinical high-risk (CHR) phase and (b) whether abnormalities in trait emotion that are associated with negative symptoms are driven by primary (i.e. idiopathic) or secondary (e.g. depression, anxiety) factors.AimsTo examine profiles of trait affective disturbance and their clinical correlates in individuals with schizophrenia and individuals at CHR for psychosis.MethodIn two studies (sample 1: 56 out-patients diagnosed with schizophrenia and 34 demographically matched individuals without schizophrenia (controls); sample 2: 50 individuals at CHR and 56 individuals not at CHR (controls)), participants completed self-report trait positive affect and negative affect questionnaires, clinical symptom interviews (positive, negative, disorganised, depression, anxiety) and community-based functional outcome measures.ResultsBoth clinical groups reported lower levels of positive affect (specific to joy among individuals with schizophrenia) and higher levels of negative affect compared with controls. For individuals with schizophrenia, links were found between positive affect and negative symptoms (which remained after controlling for secondary factors) and between negative affect and positive symptoms. For individuals at CHR, links were found between both affect dimensions and both types of symptom (which were largely accounted for by secondary factors).ConclusionsBoth clinical groups showed some evidence of reduced trait positive affect and elevated trait negative affect, suggesting that increasing trait positive affect and reducing trait negative affect is an important treatment goal across both populations. Clinical correlates of these emotional abnormalities were more integrally linked to clinical symptoms in individuals with schizophrenia and more closely linked to secondary influences such as depression and anxiety in individuals at CHR.Declaration of interestNone.

Project description:BackgroundNegative symptoms occur in individuals at ultrahigh risk (UHR) for psychosis. Although there is evidence that observer ratings of negative symptoms are associated with level of functioning, the predictive value of subjective experience in daily life for individuals at UHR has not been studied yet.ObjectiveThis study therefore aims to investigate the predictive value of momentary manifestations of negative symptoms for clinical outcomes in individuals at UHR.MethodsExperience sampling methodology was used to measure momentary manifestations of negative symptoms (blunted affective experience, lack of social drive, anhedonia, and social anhedonia) in the daily lives of 79 individuals at UHR. Clinical outcomes (level of functioning, illness severity, UHR status, and transition status) were assessed at baseline and at 1- and 2-year follow-ups.ResultsLack of social drive, operationalized as greater experienced pleasantness of being alone, was associated with poorer functioning at the 2-year follow-up (b=-4.62, P=.01). Higher levels of anhedonia were associated with poorer functioning at the 1-year follow-up (b=5.61, P=.02). Higher levels of social anhedonia were associated with poorer functioning (eg, disability subscale: b=6.36, P=.006) and greater illness severity (b=-0.38, P=.045) at the 1-year follow-up. In exploratory analyses, there was evidence that individuals with greater variability of positive affect (used as a measure of blunted affective experience) experienced a shorter time to remission from UHR status at follow-up (hazard ratio=4.93, P=.005).ConclusionsTargeting negative symptoms in individuals at UHR may help to predict clinical outcomes and may be a promising target for interventions in the early stages of psychosis.
