Abstract
Purpose: Although individual differences in temperament have been shown to influence Quality of Life (QoL) among individuals with schizophrenia, there exists considerable heterogeneity in such outcomes suggesting moderating factors. Here we used event-related potential (ERP) methodology to examine whether the processing of facial emotions moderated the association between shyness and objective QoL among adults with schizophrenia.Methods: Forty stable outpatients with schizophrenia completed measures of shyness and QoL. Early visual ERP components (P100, N170) were recorded while participants viewed emotional faces.Results: We observed a significant interaction between shyness and P100 and N170 amplitudes in response to fearful faces in predicting Intrapsychic Foundations QoL. Patients with reduced P100 and N170 amplitudes to fearful compared to neutral faces displayed the lowest QoL, but only if they were also high in shyness. We also found a significant interaction between shyness and ERP latency at the P100 and N170 in response to happy faces. Patients who displayed longer P100 and N170 latencies to happy faces compared to neutral faces and with higher shyness levels scored lower on Intrapsychic Foundations and Interpersonal Relations QoL, respectively.Conclusion: These findings suggest that the neural processing of emotional faces and shyness interact to predict aspects of QoL among outpatients with schizophrenia.

Abstract
(1) Background: Self-management is advocated as a feasible, effective intervention to support individuals to actively manage the impact of illness and live healthier lives. We sought to evaluate a piloted self-management model, SET for Health, tailored for individuals living with schizophrenia embedded within ambulatory case management. (2) Methods: A mixed-methods design engaged 40 adults living with schizophrenia in the SET for Health protocol. Functional and symptomatic outcomes were measured by self-report and clinician ratings at baseline and completion of self-management plans, on average one year later. Semi-structured qualitative client interviews invited evaluations of personal experiences with the intervention. (3) Results: Significant improvements were found concerning client illness severity, social and occupational functioning, illness management and functional recovery with reductions in emergency visits and days in hospital. Clients endorsed the value of the intervention. Baseline clinical characteristics did not predict who benefited. Participation contributed to motivational gains and quality of life. (4) Conclusions: Results confirmed self-management support embedded within traditional case management improved clients' clinical and functional status, and contributed to quality of life. Clients engaged in their recovery and actively used self-management strategies. Self-management can be successfully adopted by clients with schizophrenia regardless of age, gender, education, illness severity or duration.

Abstract
INTRODUCTION Self-management support for schizophrenia has become expected practice leaving organisations to find ways for feasible implementation. Self-management support involves a foundational cultural shift for traditional disease-based services, new ways of clients-providers working together, coupled with delivering a portfolio of tools and techniques. A new model of self-management support embedded into traditional case management services, called SET for Health (Self-management Engaging Together for Health), was designed and tailored to make such services meaningfully accessible to clients of a tertiary care centre. This paper describes the proof of concept demonstration efforts, the successes/challenges, and initial organisational changes. METHOD An integrated knowledge translation approach was selected as a means to foster organisational change grounded in users' daily realities. Piloting the model in two community case management programmes, we asked two questions: Can a model of self-management support be embedded in existing case management and delivered within routine specialised mental health services? What organisational changes support implementation? RESULTS Fifty-one clients were enroled. Indicators of feasible delivery included 72.5% completion of self-management plans in a diverse sample, exceeding the 44% set minimum; and an attrition rate of 21.6%, less than 51% set maximum. Through an iterative evaluation process, the innovation evolved to a targeted hybrid approach revolving around client goals and a core set of co-created reference tools, supplemental tools and resources. Operationalisation by use of tools was implemented to create spaces for client-provider collaborations. Monitoring of organisational changes identified realignment of practices. Changes were made to procedures and operations to further spread and sustain the model. CONCLUSION This study demonstrated how self-management support can be implemented, within existing resources, for routine delivery of specialised services for individuals living with schizophrenia. The model holds promise as a hybrid option for supporting clients to manage their own health and wellness.

Abstract
INTRODUCTION This article describes the planning and development of a novel self-management support protocol, self-management engaging together (SET) for Health, purposefully designed and embedded within traditional case management services to be accessible to people living with schizophrenia and comorbidities. Drawing on established self-management principles, SET for Health was codesigned by researchers, healthcare providers and clients, to create a practical and meaningful intervention to support the target group to manage their own health and wellness. Decision making is described behind tailoring the self-management innovation to meet the needs of an at risk, disadvantaged group served by tertiary, public health care in Canada. METHOD This integrated knowledge translation (IKT) study used a descriptive approach to document the process of planning and operationalizing the SET for Health intervention as a part of routine care in two community-based teams providing predominantly schizophrenia services. Diffusion of innovations literature informed planning. The setting was strategically prepared for organizational change. A situational assessment and theoretical frameworks identified contextual elements to be addressed. Existing established self-management approaches for mental illness were appraised. RESULTS When a review of established approaches revealed incongruence with the aims and context of service delivery, common essential elements were distilled. To facilitate collaborative client-provider self-management conversations and self-management learning opportunities, core components were operationalized by the use of tailored interactive tools. The materials coproduced by clients and providers offered joint reference tools, foundational for capacity-building and recognition of progress. CONCLUSION Planning and developing a model of self-management support for integration into traditional schizophrenia case management services required attention to the complex social ecological nature of the treatment approach and the workplace context. Demonstration of proof of concept is described in a separate paper.

Abstract
OBJECTIVE The effectiveness of ECT under naturalistic conditions has not been well-studied. The current study aimed to 1) characterize a naturalistic sample of ECT patients; and 2) examine the long-term outcomes of ECT on depressive symptoms (Beck Depression Inventory-II; BDI-II) and functional disability symptoms (WHO Disability Assessment Schedule 2.0) in this sample. METHODS Participants were adults who received ECT for a major depressive episode at an ambulatory ECT clinic between September 2010 and November 2020. Clinical and cognitive assessments were completed at baseline (n = 100), mid-ECT (n = 94), 2-4 weeks post-ECT (n = 64), 6-months post-ECT (n = 34), and 12-months post-ECT (n = 19). RESULTS At baseline, participants had severe levels of depressive symptoms (BDI-II: M = 41.0, SD = 9.4), and 62.9% screened positive for multiple psychiatric diagnoses on the MINI International Neuropsychiatric Interview. Depressive symptoms (F(4,49.1) = 49.92, P < 0.001) and disability symptoms (F(3,40.72) = 12.30, P < 0.001) improved significantly following ECT, and this was maintained at 12-months follow-up. Improvement in depressive symptoms trended towards significantly predicting reduction in disability symptoms from baseline to post-ECT, (F(1,56) = 3.67, P = 0.061). Although our clinical remission rate of 27% (BDI-II score ≤ 13 and ≥ 50% improvement) and overall response rate of 41.3% (≥ 50% improvement in BDI-II score) were lower than the rates reported in the extant RCT and community ECT literature, 36% of those treated with ECT were lost to follow-up and did not complete post-ECT rating scales. At baseline, remitters had significantly fewer psychiatric comorbidities, lower BDI-II scores, and lower disability symptoms than non-responders (P < 0.05). CONCLUSIONS Participants were severely symptomatic and clinically complex. ECT was effective at reducing depressive symptoms and functional disability in this heterogeneous sample. Although a large amount of missing data may have distorted our calculated response/remission rates, it is also likely that clinical heterogeneity and severity contribute to lower-than-expected remission and response rates to ECT.

Abstract
Although there is a long and rich empirical history of demonstrating differences on psychological self-report measures between people with schizophrenia and healthy controls, the question of whether both groups respond to psychological measures in the same way has gone largely unexplored. That is, is there measurement equivalence, or invariance, across the samples? To our knowledge, there have been no published studies on measurement equivalency in personality measures across groups diagnosed with and without schizophrenia. Here we examined the question of measurement invariance on two widely used questionnaires assessing temperament, the Cheek and Buss Shyness and Sociability Scales (CBSHY and CBSOC, respectively) between 147 stable adult outpatients with schizophrenia and 147 healthy age- and sex-matched controls. Results supported measurement invariance of the CBSHY and CBSOC across our clinical and non-clinical groups. These findings suggested that stable adult outpatients with schizophrenia and age- and sex-matched controls respond to the shyness and sociability items in the same way. We found that adults with schizophrenia reported higher levels of shyness and lower levels of sociability than healthy controls, consistent with prior studies. Findings are discussed concerning their relevance more broadly to self-report assessments of personality and psychological traits in clinical populations.

Abstract
The Wisconsin Card Sorting Test (WCST) was designed as a measure of executive functioning and is commonly used in the assessment of psychiatric disorders. The original WCST, consisting of 128 cards, has been criticized as being too lengthy for patients experiencing significant distress. Consequently, a shortened version consisting of a single 64-card deck (WCST-64) was created. The purpose of this study was to examine the comparability of the WCST and WCST-64 in 99 patients with first-episode psychosis. Findings showed the WCST-64 yielded a mean T score for perseverative responses (PR) that was 4.08 points lower than the corresponding variable from the WCST, and the correlation between the variables was r = .65. The mean discrepancy was only 2.34 for nonperseverative error (NPE) T scores and the correlation was also stronger, r = .82. Nearly half the sample (44%) had a T score discrepancy between the respective PR indexes that was greater than 1 SD, whereas this discrepancy was observed in only 4% of the sample for NPE. Based on a cut point of < 40T to define impaired versus normal performance for PR, 80% of the sample received the same classification. These findings suggest that NPE scores may be comparable across both tests. Conversely, whereas the PR score from the WCST-64 and WCST can be used as a gross measure of impairment, this score should not be used interchangeably to characterize the severity of perseverative tendencies in first-episode patients on a case-by-case basis.

Abstract
Background: Deep brain stimulation (DBS) is a neurosurgical intervention with demonstrated effectiveness for treatment resistant depression (TRD), but longitudinal studies on the stability of cognitive parameters following treatment are limited. The objectives of this study are to (i) identify baseline cognitive predictors of treatment response to subcallosal cingulate gyrus (SCG) DBS for unipolar TRD and (ii) compare neurocognitive performance prior to and 12 months after DBS implantation. Methods: Twenty unipolar TRD patients received SCG DBS for 12 months. A standardized neuropsychological battery was used to assess a range of neurocognitive abilities at baseline and after 12 months. Severity of depression was evaluated using the 17 item Hamilton Rating Scale for Depression. Results: Finger Tap-Dominant Hand Test and total number of errors made on the Wisconsin Card Sorting Test predicted classification of patients as treatment responders or non-responders, and were independent of improvement in mood. Change in verbal fluency was the only neuropsychological test that correlated with change in mood from baseline to the follow up period. None of the neuropsychological measures displayed deterioration in cognitive functioning from baseline to repeat testing at 12 months. Limitations: This was an open label study with a small sample size which limits predictive analysis. Practice effects of the neuropsychological testing could explain the improvement from baseline to follow up on some tasks. Replication using a larger sample of subjects who received neuropsychological testing before and at least 12 months after DBS surgery is required. Conclusion: These preliminary results (i) suggest that psychomotor speed may be a useful baseline predictor of response to SCG DBS treatment and (ii) support previous suggestions that SCG DBS has no deleterious effects on cognition.

Abstract
Objective: The primary aim of the present study was to compare sleep characteristics pre- and post-move into a state-of-the-art mental health facility, which offered private sleeping quarters. Background: Significant evidence points toward sleep disruption among psychiatric inpatients. It is unclear, however, how environmental factors (e.g., dorm-style rooms) impact sleep quality in this population. Methods: To assess sleep quality, a novel objective technology, actigraphy, was used before and after a facility move. Subjective daily interviews were also administered, along with the Horne–Ostberg Morningness–Eveningness Questionnaire and the Pittsburgh Sleep Quality Index. Results: Actigraphy revealed significant improvements in objective sleep quality following the facility move. Interestingly, subjective report of sleep quality did not correlate with the objective measures. Circadian sleep type appeared to play a role in influencing subjective attitudes toward sleep quality. Conclusions: Built environment has a significant effect on the sleep quality of psychiatric inpatients. Given well-documented disruptions in sleep quality present among psychiatric patients undergoing hospitalization, design elements like single patient bedrooms are highly desirable.

Abstract
OBJECTIVE The neural correlates of inhibitory deficits for emotional semantic material in persons with major depressive disorder (MDD) were investigated. METHODS Individuals (n=15) with a diagnosis of MDD or MDD in partial remission, and healthy controls (n=14) underwent recording of event-related brain potentials (ERPs) while performing a computerized emotional Stroop task. RESULTS There were no group performance differences on the emotional Stroop task. However, the analysis of ERP waveforms revealed a larger negative wave peaking at about 170ms over the left than the right hemisphere only in controls; a negative displacement (N450) at parietal sites for positive and negative words only for persons with MDD; in both groups, processing negative and positive words was associated with a positive displacement that peaked at about 450ms and was larger over the left lateral frontal region; and, the N450 modulation correlated with negative automatic thinking and depressive symptoms. CONCLUSIONS The electrophysiological data reveal early changes in neural activity associated with word processing as well as valence-related changes in the N450 component at parietal sites in MDD. SIGNIFICANCE This valence-related increase in N450 amplitude at parietal sites may reflect an automatic capture of attention by words with emotional valence.

Abstract
OBJECTIVE The objective of the study was to measure both seasonal mood change and circadian preference, and their clinical and neuropsychological correlates, in adults with ADHD during the fall/winter months. METHOD Twenty-nine adults with attention-deficit/hyperactivity disorder (ADHD) were assessed in the fall/winter season using self-report measures of ADHD, mood, seasonality, and circadian preference. Neuropsychological tests were also completed. Correlations between chronobiologic variables and clinical/neuropsychological measures were performed. RESULTS Consistent with prior work in adult ADHD, high rates of seasonal depression were reported in this sample. Based on the morningness-eveningness questionnaire, which assesses circadian preference 11 (40.7%, N = 27) subjects were designated as evening types and only 5 (18.5%) as morning types, a distribution highly discrepant with general population studies. Later circadian preference, independent of seasonality, was strongly correlated with both self-reported symptoms of ADHD and neuropsychological deficits, including impulsive responding and poor target discrimination. None of these findings was attributable to state depression. CONCLUSIONS In the fall/winter period, a mood-independent delay in circadian phase may contribute significantly to core pathology in many adults with ADHD. These findings establish a potential target for chronobiologic treatments such as light therapy in this complex population.

Abstract
OBJECTIVE In adults with attention-deficit/ hyperactivity disorder (ADHD), a delayed sleep/ activity rhythm and/or seasonal mood symptoms may contribute significantly to core pathology and disability. This study examined whether a chronobiologically based treatment, i.e., morning bright light therapy (LT), might have utility as an adjunctive treatment for adult ADHD in the fall/ winter period. METHOD Twenty-nine adults with DSM-IV ADHD were administered a standard 3-week open trial of LT during the fall or winter months. Primary outcome measures included percentage reduction on the Brown Adult ADD Scale and the Conners' Adult ADHD Scale. Secondary measures were decrease in depression scores according to the Structured Interview Guide for the Hamilton Depression Rating Scale, Seasonal Affective Disorder version; improvements on various neuropsychological tests; and shift toward an earlier circadian preference as measured by the Horne-Ostberg Morningness-Eveningness questionnaire. Regression analyses determined which variables at baseline best predicted improvement on a given outcome measure and which variables changed in parallel with one another. The study was conducted from November 2003 through February 2004. RESULTS Morning bright light therapy was associated with a significant decrease in both subjective and objective measures of core ADHD pathology, improved mood symptoms, and a significant phase advance in circadian preference. Multiple regression showed that the shift toward an earlier circadian preference with LT was the strongest predictor of improvement on both subjective and objective ADHD measures. Neither baseline global seasonality scores nor baseline depression scores strongly predicted LT effects on most measures of ADHD. CONCLUSION These findings suggest that during the fall/winter period, LT may be a useful adjunct in many adults with ADHD. Strikingly, the strongest correlate of improvement in core ADHD pathology was a phase advance in circadian preference rather than alleviation of comorbid seasonal affective disorder, suggesting important clinical benefits of LT beyond the treatment of seasonal affective disorder.

Abstract
OBJECTIVE Several antidepressants raise striatal dopamine, but the role of striatal dopamine during major depressive episodes is unclear. Striatal [(11)C]raclopride binding potential measured with positron emission tomography is an index of D(2) type receptors and is sensitive to extracellular dopamine levels (higher D(2) binding potential occurs when dopamine is lower). It was hypothesized that putamen D(2) binding potential would be higher during major depressive episodes featuring motor retardation. METHOD Drug-free, nonsmoking subjects experiencing a major depressive episode (N=21) underwent [(11)C]raclopride PET imaging as did 21 healthy age-matched comparison subjects. Motor retardation was measured with the finger tapping test. RESULTS The depressed subjects exhibiting motor retardation had significantly higher D(2) binding potential in both the left and right putamen than did healthy subjects, and putamen D(2) binding potential correlated significantly with motor speed in the depressed subjects. CONCLUSIONS The results argue that extracellular dopamine is lower in subjects experiencing a major depressive episode that features motor retardation. This depression subtype should preferentially benefit from dopamine-increasing medications and should be targeted in future clinical trials of dopamine reuptake inhibitors.

Abstract
Treatment-resistant depression is a severely disabling disorder with no proven treatment options once multiple medications, psychotherapy, and electroconvulsive therapy have failed. Based on our preliminary observation that the subgenual cingulate region (Brodmann area 25) is metabolically overactive in treatment-resistant depression, we studied whether the application of chronic deep brain stimulation to modulate BA25 could reduce this elevated activity and produce clinical benefit in six patients with refractory depression. Chronic stimulation of white matter tracts adjacent to the subgenual cingulate gyrus was associated with a striking and sustained remission of depression in four of six patients. Antidepressant effects were associated with a marked reduction in local cerebral blood flow as well as changes in downstream limbic and cortical sites, measured using positron emission tomography. These results suggest that disrupting focal pathological activity in limbic-cortical circuits using electrical stimulation of the subgenual cingulate white matter can effectively reverse symptoms in otherwise treatment-resistant depression.

Abstract
Event-related potentials (ERPs) were used to examine the impact of emotionality on false recognition. In Experiment 1, participants discriminated previously studied words from neutral and negatively valenced emotional foils. Emotional words elicited a more positive ERP than did neutral words and emotional foils were falsely recognized more often than neutral foils. In Experiment 2, the hypothesis that emotionality-based false recognition is due to the semantic cohesiveness of emotional words was tested by including a highly associated but emotionally neutral category (animals). It was emotional and not animal foils that elicited greater positivity in the ERP and increased false positive response. These data provide little support for semantic cohesiveness as the basis for false recognition effects, but are consistent with the view that the salience of emotional words can be falsely attributed to familiarity in the context of a recognition task.

Abstract
Deficits in cognition are a hallmark of schizophrenia. In the present study, the authors investigated the effects of schizophrenia on the neural correlates of conflict processing in a single-trial version of the Stroop task by using event-related brain potentials. Relative to matched controls, patients with schizophrenia showed increased Stroop interference in response time, but this effect was eliminated when the effect of response slowing was controlled. In controls, conflict processing was associated with a negative wave peaking between 400 and 500 ms (N450) and conflict sustained potential (SP) peaking between 600 and 800 ms after stimulus onset. In patients with schizophrenia, the amplitude of the N450 was significantly attenuated and the conflict SP was absent. These results provide evidence for the existence of altered neural processes associated with conflict processing that may be associated with dysfunction of the anterior cingulate and prefrontal cortex in patients with schizophrenia.

Abstract
The present study was designed to investigate the time-course of neural activity underlying the disruption of response monitoring in patients with schizophrenia. Event-related brain potentials were recorded from 12 patients with schizophrenia and from 12 age-matched controls while they performed a computerized version of the Stroop color-naming task. In control participants, but not in patients with schizophrenia, intrusion errors elicited an error-related negativity (ERN) that peaked at approximately 40 ms after the response and was maximum over the central region of the scalp. Brain electrical source analysis revealed an anterior cingulate generator for the ERN. Patients also showed reduced error-related slowing of response time following intrusion errors. These findings provide neuro-physiological evidence indicating that deficits in error monitoring in schizophrenia arise from a disruption of error-detection processes, possibly attributable to anterior cingulate dysfunction.

Abstract
Despite considerable speculation in the research literature regarding the complementarity of functional lateralization of prosodic and linguistic processes in the normal intact brain, few studies have directly addressed this issue. In the present study, behavioral laterality indices of emotional prosodic and traditional linguistic speech functions were obtained for a sample of healthy young adults, using the dichotic listening method. After screening for adequate emotional prosody and linguistic recognition abilities, participants completed the Fused Rhymed Words Test (FRWT; Wexler & Halwes, 1983) and the Dichotic Emotion Recognition Test (DERT; McNeely & Netley, 1998). Examination of the difference in ear asymmetries for these measures within individuals revealed a complementary pattern in 78% of the sample. However, the correlation between laterality quotients for the FRWT and DERT was near zero, supporting Bryden's model of "statistical" complementarity (e.g., Bryden, 1990).
