Abstract
PURPOSE To investigate the association between lifestyle and atypical antipsychotic drug use in patients with schizophrenia and the risk of constipation and to assess the impact of anxiety and depressive symptoms on constipation risk. METHODS Cross-sectional convenience sampling was employed, and 271 participants aged 20-65 were enrolled. Data were collected via a structured questionnaire comprising participants' demographic data, medication information, dietary behavior assessment, and the Baecke Physical Activity Questionnaire, Beck Depression Inventory-II, and Beck Anxiety Inventory. IBM SPSS 24.0 with multivariate logistic regression was used for data analysis. We performed a subgroup analysis of anticholinergic drugs via multivariate logistic regression. RESULTS In total, 180 participants had functional constipation; risk factors included female sex, anxiety symptoms, depressive symptoms, and quetiapine and aripiprazole use. Patients who drank more than 3,000 cc of water daily or used risperidone were less likely to have functional constipation. Depressive and anxiety symptoms were risk factors even after adjusting for sex, use of anticholinergics and laxatives, consuming two servings of fruit, consuming three servings of vegetables, consuming more than 3,000 cc of water daily, physical activity, medical comorbidity, chlorpromazine equivalent dose, and atypical antipsychotic use. Similar associations were found for two affective symptoms and functional constipation in the subgroup analysis of anticholinergic drugs. CONCLUSION The prevalence of functional constipation in patients with schizophrenia was 66.4%. The risk factors included female sex, anticholinergics, aripiprazole, quetiapine, and depressive and anxiety symptoms. Risperidone users and those who drank 3000 cc of water daily were less likely to have constipation.

Abstract
Background and Hypothesis Studies have linked auditory hallucinations (AH) in schizophrenia spectrum disorders (SCZ) to altered cerebral white matter microstructure within the language and auditory processing circuitry (LAPC). However, the specificity to the LAPC remains unclear. Here, we investigated the relationship between AH and DTI among patients with SCZ using diffusion tensor imaging (DTI). Study Design We included patients with SCZ with (AH+; n = 59) and without (AH-; n = 81) current AH, and 140 age- and sex-matched controls. Fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD), and axial diffusivity (AD) were extracted from 39 fiber tracts. We used principal component analysis (PCA) to identify general factors of variation across fiber tracts and DTI metrics. Regression models adjusted for sex, age, and age2 were used to compare tract-wise DTI metrics and PCA factors between AH+, AH-, and healthy controls and to assess associations with clinical characteristics. Study Results Widespread differences relative to controls were observed for MD and RD in patients without current AH. Only limited differences in 2 fiber tracts were observed between AH+ and controls. Unimodal PCA factors based on MD, RD, and AD, as well as multimodal PCA factors, differed significantly relative to controls for AH-, but not AH+. We did not find any significant associations between PCA factors and clinical characteristics. Conclusions Contrary to previous studies, DTI metrics differed mainly in patients without current AH compared to controls, indicating a widespread neuroanatomical distribution. This challenges the notion that altered DTI metrics within the LAPC is a specific feature underlying AH.

Abstract
INTRODUCTION Depressive symptoms are common in schizophrenia and can be seen at any stage of the disease. Although various models have been proposed to explain the development of depression in schizophrenia, studies investigating related psychological factors are scarce and the studies that have been done usually focus on only a small number of possible factors. OBJECTIVE The goal of this study was to investigate the predictability of some psychological factors on depression in patients with schizophrenia. For this purpose, patients with high and low depression scores were compared. METHODS Two groups of individuals with schizophrenia, with (n=29) and without (n=31) depression, as determined by scores on the Calgary Depression Scale in Schizophrenia, were compared using a sociodemographic data form, the Positive and Negative Syndrome Scale (PANSS), the Beck Anxiety Inventory, the Rotter Internal-External Locus 2024 of Control Scale, the Multidimensional Scale of Perceived Social Support, and the Stress Coping Styles Scale. RESULTS No differences were found between the 2 groups in terms of sociodemographic and clinical characteristics, social support scores, and coping styles. Statistically significant differences were found between the groups on the PANSS positive, negative, and general psychopathology subscales, in PANSS total scores, in anxiety scores, and in locus of control scores. CONCLUSIONS This study showed that high levels of negative, positive, and general psychopathological symptoms, external locus of control, and high anxiety scores may be predictive of depression in individuals with schizophrenia. Studies that examine psychological factors in larger patient groups may provide the opportunity to detect and target these factors earlier in the course of schizophrenia, thereby reducing morbidity and mortality.

Screening Depressive Symptoms and Incident Major Depressive Disorder Among Chinese Community Residents Using a Mobile App-Based Integrated Mental Health Care Model: Cohort Study. J Med Internet Res 2022; 24:e30907. [PMID: 35594137 PMCID: PMC9166637 DOI: 10.2196/30907] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 02/18/2022] [Accepted: 03/30/2022] [Indexed: 02/06/2023] Open
Abstract
Background Depression is associated with significant morbidity and human capital costs globally. Early screening for depressive symptoms and timely depressive disorder case identification and intervention may improve health outcomes and cost-effectiveness among affected individuals. China’s public and academic communities have reached a consensus on the need to improve access to early screening, diagnosis, and treatment of depression. Objective This study aims to estimate the screening prevalence and associated factors of subthreshold depressive symptoms among Chinese residents enrolled in the cohort study using a mobile app–based integrated mental health care model and investigate the 12-month incidence rate and related factors of major depressive disorder (MDD) among those with subthreshold depressive symptoms. Methods Data were drawn from the Depression Cohort in China (DCC) study. A total of 4243 community residents aged 18 to 64 years living in Nanshan district, Shenzhen city, in Guangdong province, China, were encouraged to participate in the DCC study when visiting the participating primary health care centers, and 4066 (95.83%) residents who met the DCC study criteria were screened for subthreshold depressive symptoms using the Patient Health Questionnaire-9 at baseline. Of the 4066 screened residents, 3168 (77.91%) with subthreshold depressive symptoms were referred to hospitals to receive a psychiatric diagnosis of MDD within 12 months. Sleep duration, anxiety symptoms, well-being, insomnia symptoms, and resilience were also investigated. The diagnosis of MDD was provided by trained psychiatrists using the Mini-International Neuropsychiatric Interview. Univariate and multivariate logistic regression models were performed to explore the potential factors related to subthreshold depressive symptoms at baseline, and Cox proportional hazards models were performed to explore the potential factors related to incident MDD. Results Anxiety symptoms (adjusted odds ratio [AOR] 1.63, 95% CI 1.42-1.87) and insomnia symptoms (AOR 1.13, 95% CI 1.05-1.22) were associated with an increased risk of subthreshold depressive symptoms, whereas well-being (AOR 0.93, 95% CI 0.87-0.99) was negatively associated with depressive symptoms. During the follow-up period, the 12-month incidence rate of MDD among participants with subthreshold depressive symptoms was 5.97% (189/3168). After incorporating all significant variables from the univariate analyses, the multivariate Cox proportional hazards model reported that a history of comorbidities (adjusted hazard ratio [AHR] 1.49, 95% CI 1.04-2.14) and anxiety symptoms (AHR 1.13, 95% CI 1.09-1.17) were independently associated with an increased risk of incident MDD. The 5-item World Health Organization Well-Being Index was associated with a decreased risk of incident MDD (AHR 0.90, 95% CI 0.86-0.94). Conclusions Elevated anxiety symptoms and unfavorable general well-being were significantly associated with subthreshold depressive symptoms and incident MDD among Chinese residents in Shenzhen. Early screening for subthreshold depressive symptoms and related factors may be helpful for identifying populations at high risk of incident MDD.

Abstract
To investigate the mediating roles of community integration and positive thinking on the relationship between depression and mental health recovery among community dwelling people with mental disorders in South Korea. A cross-sectional, descriptive study was utilized. Data were collected from 167 community-dwelling people with mental disorders who did not use the day program at community mental health centers. Data were collected from November 20, 2018, to February 15, 2019. Both community integration and positive thinking were found to mediate the effects of depression on mental health recovery. The mediating effect of positive thinking was significantly greater than that of community integration. This study added evidence for a significant multiple mediating effect of community integration and positive thinking on the relationship between depression and mental health recovery in community-dwelling people with mental disorders. Although the consumer-centered recovery paradigm of people with mental health difficulties is of global importance, little research has been conducted on mental health recovery among community-dwelling people with mental disorders who do not use the day program at community mental health centers. It was found that community integration and positive thinking mediated the effects of depression on mental health recovery, with positive thinking mediating this relationship the most. Thus, these results suggest a specific direction of community mental health services to promote mental health recovery for people with mental disorders who do not have access to community mental health services.

Abstract
Enormous efforts have been made to unveil the etiology of auditory hallucinations (AHs), and multiple genetic and neural factors have already been shown to have their own roles. Previous studies have shown that AHs in schizophrenia vary from those in other disorders, suggesting that they have unique features and possibly distinguishable mechanisms worthy of further investigation. In this review, we intend to offer a comprehensive summary of current findings related to AHs in schizophrenia from aspects of genetics and transcriptome, neurophysiology (neurometabolic and electroencephalogram studies), and neuroimaging (structural and functional magnetic resonance imaging studies and transcriptome–neuroimaging association study). Main findings include gene polymorphisms, glutamate level change, electroencephalographic alterations, and abnormalities of white matter fasciculi, cortical structure, and cerebral activities, especially in multiple regions, including auditory and language networks. More solid and comparable research is needed to replicate and integrate ongoing findings from multidimensional levels.

Abstract
INTRODUCTION Patients with schizophrenia frequently present with visual disturbances including hallucination, and this symptom is particularly prevalent in individuals with comorbid depressive disorders. Currently, little is known about the neurobiological mechanisms of such psychiatric symptoms, and few explanations for the co-occurrence of schizophrenia, depression, and visual disturbances are available. METHODS In this study, we generated a mouse schizophrenia model in which depressive symptoms were also induced. We adopted in vivo two-photon calcium imaging and ex vivo electrophysiological recording of the primary visual cortex to reveal the synaptic transmission and neural activity in the mouse schizophrenia model. RESULTS In vivo two-photon calcium imaging and ex vivo electrophysiological recording of the primary visual cortex revealed impaired synaptic transmission and abnormal neural activity in the schizophrenia model, but not in the depression model. These functional deficits were most prominent in the combined schizophrenia and depression model. CONCLUSION Overall, our data support a mechanism by which the visual cortex plays a role in visual disturbances in schizophrenia.

Abstract
BACKGROUND Auditory verbal hallucinations (AVHs) and depressive symptoms are highly prevalent in schizophrenia, and recent progress has been made in understanding the reciprocal deterioration of both symptoms through structural and functional brain imaging studies. To date, there is limited literature on this topic. In this review, we synthesized the recent literature on the neuroimaging features of schizophrenia patients with concurrent AVHs and depressive symptoms. METHODS A literature search was conducted with the major databases using the keywords, mainly including schizophrenia, AVHs, depression, neuropsychiatric disorders, brain imaging, and magnetic resonance imaging. RESULTS The existing studies have shown that AVHs and depressive symptoms reciprocally deteriorate in patients with schizophrenia, which has challenged the conventional treatment of the disease. Interestingly, repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) therapies have emerged as two efficacious brain stimulation treatments that can normalize the brain regions associated with the symptoms, as shown through functional and structural brain imaging studies. In light of these important findings, there is an urgent need to conduct in-depth neuronal mechanistic studies to identify targets for stimulation therapy. CONCLUSIONS These new findings may elucidate the pathological mechanisms underlying schizophrenia with concurrent AVHs and depressive symptoms. Furthermore, this review has important clinical implications for developing novel therapeutic strategies to alleviate the reciprocal deterioration AVHs and depressive symptoms of schizophrenia patients.

Abstract
As a risk factor of hallucination proneness, the level of mindfulness has not yet been investigated in non-clinical participants. Other potential mediators, such as mental distress (depression, anxiety, and stress) which contribute to hallucination proneness also need to be assessed. This study investigated the mediating effect of mental distress in predicting hallucination proneness based on mindfulness. A number of 168 Iranian university students completed three questionnaires: (1) the five-facet mindfulness questionnaire, (2) the depression, anxiety and stress scale; and (3) the revised hallucination scale. The results showed that there was a significant association between levels of mindfulness and hallucination proneness. Mental distress has a significant effect on four facets of mindfulness questionnaire and an insignificant effect on one facet (awareness) in predicting hallucination. These effects were both direct and indirect. The indirect effect was developed by the mediating role of mental distress.

Abstract
Comorbid major depressive disorder (MDD) in schizophrenia (SZ; SZ-MDD) has been identified as a major prognostic factor. However, the prevalence and associated factors of SZ-MDD have never been explored in a meta-analysis. All studies assessing the prevalence of SZ-MDD in stabilized outpatients with a standardized scale or with structured interviews were included. The Medline, Web of Science, PsycINFO, and Google Scholar databases were searched. Using random effects models, we calculated the pooled estimate of the prevalence of SZ-MDD. We used meta-regression and subgroup analyses to evaluate the potential moderators of the prevalence estimates, and we used the leave-one-out method for sensitivity analyses. Of the 5633 potentially eligible studies identified, 18 studies (n = 6140 SZ stabilized outpatients) were retrieved in the systematic review and included in the meta-analysis. The pooled estimate of the prevalence of SZ-MDD was 32.6% (95% CI: 27.9-37.6); there was high heterogeneity (I2 = 92.6%), and Egger's test did not reveal publication bias (P = .122). The following factors were found to be sources of heterogeneity: publication in or after 2015, the inclusion of patients from larger studies, the assessment tools, the inclusion of patients with substance use disorder or somatic chronic diseases, age, education level, the lifetime number of hospitalizations, and antidepressant use. Two-thirds of the extracted variables could not be explored due to an insufficient amount of published data. The prevalence of MDD is high among SZ individuals. Healthcare providers and public health officials should have an increased awareness of the burden of SZ-MDD.

Wang TT, Beckstead JW, Yang CY. Social interaction skills and depressive symptoms in people diagnosed with schizophrenia: The mediating role of auditory hallucinations. Int J Ment Health Nurs 2019; 28:1318-1327. [PMID: 31433115 DOI: 10.1111/inm.12643] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2018] [Revised: 07/09/2019] [Accepted: 07/16/2019] [Indexed: 11/30/2022]
Abstract
Past studies have presented evidence that depressive symptoms are affected in different ways by social interaction skills and auditory hallucinatory symptoms in people with schizophrenia. However, few studies have focused on examining the relationship among auditory hallucinatory severity, social interaction skills, and depressive symptoms. This study aimed to explore the mediating effect of auditory hallucinatory severity on social interaction skills and depressive symptoms in people with long-term schizophrenia. We propose that auditory hallucination severity functions as a mechanism through which impaired social interaction skills increase depressive symptoms. In this study, a convenience sample of 186 people with schizophrenia was obtained from hospital-based rehabilitation wards. Four instruments were used: A demographic data questionnaire, the Assessment of Communication and Interaction Skills-Chinese version, the Characteristics of Auditory Hallucinations Questionnaire, and the Beck Depression Inventory II. To investigate the mediating effect of auditory hallucinatory severity after controlling for six covariates, we tested an indirect effect in a simple mediation model using the SPSS macro PROCESS, which is a regression-based approach. The indirect effect and the results of Sobel's test were significant (Z = -2.824, P = 0.005), which confirms that auditory hallucination severity mediates social interaction skills and depressive symptoms. This finding suggests that psychiatric nurses must teach people with schizophrenia to use auditory hallucination management strategies to prevent them from becoming immersed in auditory hallucinations and reducing their social interaction with the real world, so that depressive symptoms can be improved.
