Abstract
BACKGROUND AND AIMS Social determinants of health (SDoHs) impact the development and course of schizophrenia-spectrum psychotic disorders (SSPDs). Yet, we found no published scholarly reviews of psychometric properties and pragmatic utility of SDoH assessments among people with SSPDs. We aim to review those aspects of SDoH assessments. STUDY DESIGN PsychInfo, PubMed, and Google Scholar databases were examined to obtain data on reliability, validity, administration process, strengths, and limitations of the measures for SDoHs identified in a paired scoping review. STUDY RESULTS SDoHs were assessed using different approaches including self-reports, interviews, rating scales, and review of public databases. Of the major SDoHs, early-life adversities, social disconnection, racism, social fragmentation, and food insecurity had measures with satisfactory psychometric properties. Internal consistency reliabilities-evaluated in the general population for 13 measures of early-life adversities, social disconnection, racism, social fragmentation, and food insecurity-ranged from poor to excellent (0.68-0.96). The number of items varied from 1 to more than 100 and administration time ranged from less than 5 minutes to over an hour. Measures of urbanicity, low socioeconomic status, immigration status, homelessness/housing instability, and incarceration were based on public records or targeted sampling. CONCLUSIONS Although the reported assessments of SDoHs show promise, there is a need to develop and test brief but validated screening measures suitable for clinical application. Novel assessment tools, including objective assessments at individual and community levels utilizing new technology, and sophisticated psychometric evaluations for reliability, validity, and sensitivity to change with effective interventions are recommended, and suggestions for training curricula are offered.

Abstract
Studies and findings regarding the impact of schizophrenia on quality of life (QOL) has been highly variable. This meta-analysis compared QOL between schizophrenia subjects and healthy controls with a focus on standardized measures. A systematic literature search was conducted through Pubmed, PsycINFO, EMBASE, Cochrane Library and Web of Science databases. Only studies using the World Health Organization Quality of Life (WHOQOL) or its brief version or the Short Form-36 Health Survey (SF-36) were included. Fifteen case-control studies with 2195 schizophrenia subjects and 1508 healthy controls were included in this meta-analysis. The WHOQOL/WHOQOL-BREF score was significantly lower in physical health (SMD = -1.80, 95% CI: -2.31 to -1.28, P < 0.001), psychological health (SMD = -1.28, 95% CI: -1.72 to -0.83, P < 0.001), social relationships (SMD = -1.60, 95% CI: -2.05 to -1.15, P < 0.001), and environment domains (SMD = -0.98, 95% CI: -1.38 to -0.59, P < 0.001) in schizophrenia subjects compared to controls. The SF-36 score was significantly lower in both physical (SMD = -1.09, 95% CI: -1.41 to -0.76, P < 0.001 and mental health domains (SMD = -2.08, 95% CI: -3.58 to -0.59, P = 0.006) in schizophrenia subjects than in controls. Subgroup and meta-regression analyses found that age, male gender, illness duration and income have significant moderating effects on QOL. The meta-analysis of studies with standardized measures confirmed that QOL in schizophrenia subjects is significantly lower than healthy controls. Effective interventions should be developed to improve QOL for this population.

Abstract
Anxiety symptoms can occur in up to 65 % of patients with schizophrenia, and may reach the threshold for diagnosis of various comorbid anxiety disorders, including obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD). We review the clinical presentation, diagnosis, neurobiology, and management of anxiety in patients with schizophrenia, with a particular focus on pharmacotherapy. The prevalence of any anxiety disorder (at syndrome level) in schizophrenia is estimated to be up to 38 %, with social anxiety disorder (SAD) being the most prevalent. Severity of positive symptoms may correlate with severity of anxiety symptoms, but anxiety can occur independently of psychotic symptoms. While anxiety may be associated with greater levels of insight, it is also associated with increased depression, suicidality, medical service utilization, and cognitive impairment. Patients with anxiety symptoms are more likely to have other internalizing symptoms as opposed to externalizing symptoms. Diagnosis of anxiety in schizophrenia may be challenging, with positive symptoms obscuring anxiety, lower levels of emotional expressivity and communication impeding diagnosis, and conflation with akathisia. Higher diagnostic yield may be achieved by assessment following the resolution of the acute phase of psychosis as well as by the use of screening questions and disorder-specific self-report instruments. In schizophrenia patients with anxiety, there is evidence of underactive fear circuitry during anxiety-provoking stimuli but increased autonomic responsivity and increased responsiveness to neutral stimuli. Recent findings implicate the serotonin transporter (SERT) genes, brain-derived neurotropic factor (BDNF) genes, and the serotonin 1a (5HT1a) receptor, but are preliminary and in need of replication. There are few randomized controlled trials (RCTs) of psychotherapy for anxiety symptoms or disorders in schizophrenia. For pharmacotherapy, data from a few randomized and open trials have shown that aripiprazole and risperidone may be efficacious for obsessive-compulsive and social anxiety symptoms, and quetiapine and olanzapine for generalized anxiety. Older agents such as trifluoperazine may also reduce comorbid anxiety symptoms. Alternative options include selective serotonin re-uptake inhibitor (SSRI) augmentation of antipsychotics, although evidence is based on a few randomized trials, small open trials, and case series, and caution is needed with regards to cytochrome P450 interactions and QTc interval prolongation. Buspirone and pregabalin augmentation may also be considered. Diagnosis and treatment of anxiety symptoms and disorders in schizophrenia is an important and often neglected aspect of the management of schizophrenia.

Abstract
BACKGROUND Considering that depressive and anxiety symptoms are common in schizophrenia, this study investigated whether the severity of a psychotic episode in an acute phase schizophrenia cohort is predictive of concurrent depressive and anxiety features. METHOD Fifty one recently hospitalised patients suffering from acute phase schizophrenia participated prospectively in a cross-sectional study. The severity of the psychotic episode, the depressive features and the anxiety features were measured by the Structured Clinical Interview for Positive and Negative Syndrome Scale (SCI-PANSS), the Calgary Depression Scale for Schizophrenia (CDSS), the Hamilton Anxiety Rating Scale (HAM-A) and the Staden Schizophrenia Anxiety Rating Scale (S-SARS). The total SCI-PANSS-scores were adjusted to exclude appropriately the depression or anxiety items contained therein. To examine akathisia as potential confounder, the Barnes Akathisia Scale was also applied. The relationships were examined using linear regressions and paired t-tests were performed between lower and higher scores on the SCI-PANSS. RESULTS A higher adjusted total SCI-PANSS-score predicted statistically significantly higher scores for depressive features on the CDSS (p < 0.0001) and for anxiety features on the HAM-A (p = 0.05) and the S-SARS (p < 0.0001). The group that scored more or equal to the median (=99) of the adjusted total SCI-PANSS, scored significantly higher (p < 0.0001) on the CDSS, the HAM-A and the S-SARS than the group scoring below it. Akathisia measured distinctly different (p < 0.0001) from both the anxiety measures. CONCLUSION The study suggests that the severity of a psychotic episode in acute phase schizophrenia predicts the severity of concurrent depressive and anxiety features respectively.

Abstract
The recently published DSM-5 contains a number of changes pertinent to panic disorder and agoraphobia. These changes include separation of panic disorder and agoraphobia into separate diagnoses, the addition of criteria and guidelines for distinguishing agoraphobia from specific phobia, the addition of a 6-month duration requirement for agoraphobia, the addition of panic attacks as a specifier to any DSM-5 diagnosis, changes to descriptors of panic attack types, as well as various changes to the descriptive text. It is crucial that clinicians and researchers working with individuals presenting with panic attacks and panic-like symptoms understand these changes. The purpose of the current paper is to provide a summary of the main changes, to critique the changes in the context of available empirical evidence, and to highlight clinical implications and potential impact on mental health service utilization. Several of the changes have the potential to improve access to evidence-based treatment; yet, although certain changes appear justified in that they were based on converging evidence from different empirical sources, other changes appear questionable, at least based on the information presented in the DSM-5 text and related publications. Ongoing research of DSM-5 panic disorder and agoraphobia as well as application of the new diagnostic criteria in clinical contexts is needed to further inform the strengths and limitations of DSM-5 conceptualizations of panic disorder and agoraphobia.

Abstract
Diagnostic and treatment hierarchical reductionisms have led to an oversight of anxiety syndromes in schizophrenia. Nevertheless, recent data have indicated that anxiety can be a significant source of morbidity in this patient group. This paper reviews current knowledge concerning anxiety comorbidity in schizophrenia, its epidemiology, course, and treatment. A computerized search of the literature published from 1966 to July 2012 was conducted on Medline. Comorbid anxiety disorders are present in 38.3% of subjects with schizophrenia spectrum disorders. The most common anxiety disorder is social phobia followed by post-traumatic stress disorder and obsessive compulsive disorder. The presence and severity of symptoms of anxiety are associated with more severe clinical features and poorer outcomes. Available literature on the treatment consists primarily of case reports and open trials. Fragments of data support the notion of treating these anxiety states and syndromes as co-occurring clinical conditions with adjunctive medications and psychosocial interventions. However, additional work remains to be done on this issue before firm conclusions can be drawn.

Abstract
The clinical relevance of anxiety disorders in schizophrenia has been neglected for a long time and has only recently become the subject of a systematic investigation, although its consequences may have a very negative impact on the outcome and considerably worsen the trajectory of the disease. This could be originally related to the hierarchical organization of the Diagnostic and Statistical Manual of Mental Disorders (DSM) and to the lack of assessment instruments. In this article, we will review the most recent literature concerning two of the most impairing anxiety disorders in comorbidity with schizophrenia, such as panic disorder and social anxiety disorder, briefly analyze the role of anxiety in the prodromal phase of psychosis and provide suggestions for the clinical assessment.

Abstract
BACKGROUND Body dysmorphic disorder (BDD) is a common and often severe disorder. Clinical observations suggest that panic attacks triggered by BDD symptoms may be common. However, to our knowledge, no study has examined such panic attacks in BDD. We investigated the prevalence, clinical features, and correlates of BDD- triggered panic attacks in individuals with this disorder. METHODS Panic attacks and other variables were assessed using reliable and valid measures in 76 individuals with lifetime DSM-IV BDD. RESULTS 28.9% (95% CI, 18.5%-39.4%) of participants reported lifetime panic attacks triggered by BDD symptoms. The most common triggers of such attacks were feeling that others were looking at or scrutinizing the perceived appearance defects (61.9%), looking in the mirror at perceived defects (38.1%), and being in bright light where perceived defects would be more visible (23.8%). The most common panic attack symptoms were palpitations (86.4%), sweating (66.7%), shortness of breath (63.6%), trembling or shaking (63.6%), and fear of losing control or going crazy (63.6%). Compared to participants without such panic attacks, those with BDD-triggered panic attacks had more severe lifetime BDD, social anxiety, and depressive symptoms, as well as poorer functioning and quality of life on a number of measures. They were also less likely to be employed and more likely to have been psychiatrically hospitalized and to have had suicidal ideation due to BDD. CONCLUSIONS Panic attacks triggered by BDD-related situations appear com- mon in individuals with this disorder. BDD-triggered panic attacks were associated with greater symptom severity and morbidity.

Schizophrenia comorbid with panic disorder: evidence for distinct cognitive profiles. Psychiatry Res 2012; 197:206-11. [PMID: 22417926 PMCID: PMC3393808 DOI: 10.1016/j.psychres.2012.01.017] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2011] [Revised: 10/04/2011] [Accepted: 01/13/2012] [Indexed: 11/24/2022]
Abstract
Patients with comorbid schizophrenia and panic symptoms share a distinct clinical presentation and biological characteristics, prompting some to propose panic psychosis as a separate subtype of schizophrenia. Less is known about these patients' neuropsychological profiles, knowledge of which may facilitate target-specific treatments and research into the etiopathophysiology for such cases. A total of 255 schizophrenia patients with panic disorder (n=39), non-panic anxiety disorder (n=51), or no anxiety disorder (n=165) were assessed with the Wechsler Adult Intelligence Scale-Revised, the Wisconsin Card Sorting Test, the Trail Making Test, the Controlled Oral Word Association Test, the Animal Naming subtest of the Boston Diagnostic Aphasia Examination, and the Wechsler Memory Scale-Revised. Psychotic symptoms were assessed with the Positive and Negative Syndrome Scale. Patients with panic disorder demonstrated a higher verbal IQ and better problem solving, set switching, delayed recall, attention, and verbal fluency as compared to schizophrenia patients without comorbid anxiety. The schizophrenia-panic group reported a higher level of dysthymia on stable medication. Our findings suggest that patients with schizophrenia and comorbid panic disorder exhibit distinct cognitive functioning when compared to other schizophrenia patients. These data offer further support for a definable panic-psychosis subtype and suggest new etiological pathways for future research.
