Negative symptoms observed in patients with psychotic disorders undermine quality of life and functioning. Antipsychotic medications have a limited impact. Psychological and psychosocial ...interventions, with medication, are recommended. However, evidence for the effectiveness of specific non-biological interventions warrants detailed examination.
To conduct a meta-analytic and systematic review of the literature on the effectiveness of non-biological treatments for negative symptoms in psychotic disorders.
We searched for randomised controlled studies of psychological and psychosocial interventions in psychotic disorders that reported outcome on negative symptoms. Standardised mean differences (SMDs) in values of negative symptoms at the end of treatment were calculated across study domains as the main outcome measure.
A total of 95 studies met our criteria and 72 had complete quantitative data. Compared with treatment as usual cognitive-behavioural therapy (pooled SMD -0.34, 95% CI -0.55 to -0.12), skills-based training (pooled SMD -0.44, 95% CI -0.77 to -0.10), exercise (pooled SMD -0.36, 95% CI -0.71 to -0.01), and music treatments (pooled SMD -0.58, 95% CI -0.82 to -0.33) provide significant benefit. Integrated treatment models are effective for early psychosis (SMD -0.38, 95% CI -0.53 to -0.22) as long as the patients remain in treatment. Overall quality of evidence was moderate with a high level of heterogeneity.
Specific psychological and psychosocial interventions have utility in ameliorating negative symptoms in psychosis and should be included in the treatment of negative symptoms. However, more effective treatments for negative symptoms need to be developed.
Objective
Access to adequate mental health (MH) services is necessary for nearly half of Canadian youth (18–24 years) who enroll in post-secondary education given the relatively high risk of MH ...problems. Our objectives were to determine the status of MH services available to students in post-secondary institutions in Canada and to determine the extent to which these services are based on the principles of a high-quality youth MH (YMH) service.
Method
Information on MH services was collected from websites of a representative sample (N = 67) of post-secondary institutions across all provinces. Data were analysed descriptively according to four categories (universities with a Faculty of Medicine (FoM) n = 18, other large universities n = 15, small universities n = 16, and colleges n = 18).
Results
Most institutions provided 24-h crisis line support (84%) and indicated the availability of free counselling or psychotherapy (n = 62 of 67, 92.5%), while only a minority indicated provision of an initial clinical assessment (25%) and provision of multiple sessions of therapy (37%). Wait time for first contact was impressively low (<72 h) in the minority of institutions (40%) which provided this information. Access to either a prescribing physician or psychiatrist was infrequent, though several mentioned an unexplained model of “stepped care” and outside referrals. While relevant information was not uniformly easy to access, larger institutions both with and without a FoM appear to be better poised to provide MH services. None of the institutions appeared to follow all the principles of service delivery recommended for a high-quality YMH, with only two showing early identification activities.
Conclusions
MH services in post-secondary institutions may need a transformation similar to YMH services, including a clear pathway to care, an initial clinical assessment, early identification of MHA disorders, and better utilization of institutional resources through greater collaboration and matching of timely interventions to the presenting problems.
In this article we have provided a perspective on the importance and value of youth mental health services for society and argued that advancing youth mental health services should be the number one ...priority of health services in Canada. Using the age period of 12–25 years for defining youth, we have provided justification for our position based on scientific evidence derived from clinical, epidemiological and neurodevelopmental studies. We have highlighted the early onset of most mental disorders and substance abuse as well as their persistence into later adulthood, the long delays experienced by most help seekers and the consequence of such delays for young people and for society in general. We have also provided a brief review of the current gross inadequacies in access and quality of care available in Canada. We have argued for the need for a different conceptual framework of youth mental disorders as well as for a transformation of the way services are provided in order not only to reduce the unmet needs but also to allow a more meaningful exploration of the nature of such problems presenting in youth and the best way to treat them. We have offered some ideas based on previous work completed in this field as well as current initiatives in Canada and elsewhere. Any transformation of youth mental health services in Canada must take into consideration the significant geographic, cultural and political diversity across the provinces, territories and indigenous peoples across this country.
Objective:There is little understanding of service users' conceptions of recovery in the early phase of psychotic disorders. An enhanced understanding of personal notions of recovery may help with ...the development and evaluation of interventions that address the concerns of service users. This study examined personal definitions of recovery among individuals recently treated in a specialized early-intervention service in Canada.
Methods:Semistructured interviews were carried out with 30 individuals three to five years after initial treatment of a first episode of psychosis. Interpretative phenomenological analysis was used to examine participants' personal meanings of recovery. A typology of recovery definitions was constructed.
Results:A majority of individuals considered themselves to be recovered. Responses indicated that recovery is a multidimensional experience and is often a personalized and achievable goal at this early stage in treatment. Individuals described recovery as improvement in one or more of three domains: illness recovery, psychological and personal recovery, and social and functional recovery. There was variation in the extent to which individuals perceived that recovery involved alleviation of symptoms and elimination of underlying vulnerability to illness.
Conclusions:There were several components of the personal meanings of recovery from a first episode of psychosis and variations in the emphasis that individuals placed on each component. An overall positive outlook may be a function of younger age, shorter duration of illness, and receipt of client-centered comprehensive and phase-specific treatment. Improved understanding of personal notions of recovery can guide clinical practices to address service users' recovery goals. (Psychiatric Services 63:548–553, 2012; doi: 10.1176/appi.ps.201100424)
Early life adversity is associated with increased risk for psychosis onset and poor clinical outcome. Male compared to female patients often show a more severe course of psychotic illness. The aim of ...the present study was to investigate gender differences in childhood trauma (CT) and their impact on symptomatic and functional outcome following psychosis onset.
The study included 210 patients (144 men, 66 women) diagnosed with a first-episode of psychosis (FEP). Early adversity was assessed with the Childhood Trauma Questionnaire. Psychotic symptoms and general functioning were rated with the Brief Psychiatric Rating Scale and Global Assessment of Functioning scale at baseline, 12 and 24 months of follow-up in an established early intervention service.
Male patients reported higher rates of physical or emotional neglect, whereas female patients indicated significantly higher rates of emotional abuse. More severe CT was related to higher levels of depression in women and to negative symptoms in men. Distinct CT effects were observed on positive and negative symptom severity and global functioning in male patients at 24 months. Emotional abuse was the strongest predictor of depression in both genders. In male patients only, emotional abuse predicted positive symptom severity and impaired global functioning, whereas emotional neglect predicted more severe negative symptoms.
Our results suggest differences in CT experiences in male and female FEP patients, with a more pronounced impact on longer-term outcome in male patients. The findings support the notion that sex differences in stress vulnerability account for the relatively poor illness course in male psychosis patients.
Negative symptoms represent an unmet therapeutic need in many patients with schizophrenia. In an extension to our previous voxel-based morphometry findings, we employed a more specific, vertex-based ...approach to explore cortical thinning in relation to persistent negative symptoms (PNS) in non-affective first-episode of psychosis (FEP) patients to advance our understanding of the pathophysiology of primary negative symptoms.
This study included 62 non-affective FEP patients and 60 non-clinical controls; 16 patients were identified with PNS (i.e., at least 1 primary negative symptom at moderate or greater severity sustained for at least 6 consecutive months). Using cortical thickness analyses, we explored for differences between PNS and non-PNS patients as well as between each patient group and healthy controls; cut-off threshold was set at p<0.01, corrected for multiple comparisons.
A thinner cortex prominently in the right superior temporal gyrus extending into the temporo-parietal junction (TPJ), right parahippocampal gyrus, and left orbital frontal gyrus was identified in PNS patients vs. non-PNS patients. Compared with healthy controls, PNS patients showed a thinner cortex prominently in the right superior temporal gyrus, right parahippocampal gyrus, and right cingulate; non-PNS patients showed a thinner cortex prominently in the parahippocampal gyrus bi-laterally.
Cortical thinning in the early stages of non-affective psychosis is present in the frontal and temporo-parietal regions in patients with PNS. With these brain regions strongly related to social cognitive functioning, our finding suggests a potential link between primary negative symptoms and social cognitive deficits through common brain etiologies.

Accurate automated quantification of subcortical structures is a greatly pursued endeavour in neuroimaging. In an effort to establish the validity and reliability of these methods in defining the ...striatum, globus pallidus, and thalamus, we investigated differences in volumetry between manual delineation and automated segmentations derived by widely used FreeSurfer and FSL packages, and a more recent segmentation method, the MAGeT-Brain algorithm. In a first set of experiments, the basal ganglia and thalamus of thirty subjects (15 first episode psychosis FEP, 15 controls) were manually defined and compared to the labels generated by the three automated methods. Our results suggest that all methods overestimate volumes compared to the manually derived “gold standard”, with the least pronounced differences produced using MAGeT. The least between-method variability was noted for the striatum, whereas marked differences between manual segmentation and MAGeT compared to FreeSurfer and FSL emerged for the globus pallidus and thalamus. Correlations between manual segmentation and automated methods were strongest for MAGeT (range: 0.51 to 0.92; p<0.01, corrected), whereas FreeSurfer and FSL showed moderate to strong Pearson correlations (range 0.44–0.86; p<0.05, corrected), with the exception of FreeSurfer pallidal (r=0.31, p=0.10) and FSL thalamic segmentations (r=0.37, p=0.051). Bland-Altman plots highlighted a tendency for greater volumetric differences between manual labels and automated methods at the lower end of the distribution (i.e. smaller structures), which was most prominent for bilateral thalamus across automated pipelines, and left globus pallidus for FSL.
We then went on to examine volume and shape of the basal ganglia structures using automated techniques in 135 FEP patients and 88 controls. The striatum and globus pallidus were significantly larger in FEP patients compared to controls bilaterally, irrespective of the method used. MAGeT-Brain was more sensitive to shape-based group differences, and uncovered widespread surface expansions in the striatum and globus pallidus bilaterally in FEP patients compared to controls, and surface contractions in bilateral thalamus (FDR-corrected). By contrast, after using a recommended cluster-wise thresholding method, FSL only detected differences in the right ventral striatum (FEP>Control) and one cluster of the left thalamus (Control>FEP).
These results suggest that different automated pipelines segment subcortical structures with varying degrees of variability compared to manual methods, with particularly pronounced differences found with FreeSurfer and FSL for the globus pallidus and thalamus.
•Manual segmentation of subcortical structure is evaluated against 3 automated tools.•Correspondence with manual labels was greatest with MAGeT-Brain.•Greatest between-method variability was noted for FreeSurfer and FSL-FIRST.•Larger striatum and pallidum were found in first episode psychosis across methods.•Subcortical shape profiles in patients vs. controls differed between MAGeT and FSL.
Objective:Although the negative consequences associated with first-episode psychosis (FEP) have been well investigated, relatively less is known about positive changes that people may experience ...after FEP. Existing literature is disparate and in need of synthesis. Such a synthesis can inform the design of mental health services that foster strengths, hope, and optimism. The objective of this study was to synthesize the literature on how positive change is experienced after FEP by affected persons and their families and friends and to delineate the individual, social, and structural factors facilitating positive change.Methods:A librarian-assisted systematic review of quantitative, qualitative, and mixed-methods studies published in English between 1970 and 2015 was conducted. Articles identified from three databases (PubMed, PsycINFO, and Embase) and through additional search strategies were screened. Results sections were open coded and analyzed by using thematic synthesis.Results:Of the 2,777 studies identified, 40 were retained. The synthesis of findings showed that after FEP, service users and their families and friends experienced positive changes at the individual (for example, more insight and clarity), interpersonal (for example, improved relationships), and spiritual levels (for example, greater religiosity). In addition to being facilitated by mental health services, these positive changes were enabled by personal (for example, motivation), social (for example, family support), and spiritual (for example, prayer) factors.Conclusions:Suffering is a core experience of FEP from which a range of positive changes can follow among service users and their families and friends. It may be beneficial for mental health services to specifically strive to promote these positive changes.
