Associations between constipation risk and lifestyle, medication use, and affective symptoms in patients with schizophrenia: a multicenter cross-sectional study.

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.

Association of the AhR, ARNT, and AhRR gene polymorphisms and cord blood AhR levels with elevated cord blood IgE susceptibility in Taiwan mother-infant pairs: a nested case-control study.

The roles of aryl hydrocarbon receptor (AhR), AhR-nuclear translocator (ARNT), and AhR repressor (AhRR) genes in the elevation of cord blood IgE (CbIgE) remained unclear. Our aims were to determine the polymorphisms of AhR, ARNT, and AhRR genes, cord blood AhR (CBAhR) level, and susceptibility to elevation of CbIgE. 206 infant-mother pairs with CbIgE>=0.35 IU/ml and 421 randomly selected controls recruited from our previous study. Genotyping was determined using TaqMan assays. Statistical analysis showed AhR rs2066853 (GG vs. AA+AG: adjusted OR (AOR)=1.5, 95%CI=1.10-2.31 and AOR=1.60, 95%CI=1.06-2.43, respectively) and the combination of AhR rs2066853 and maternal total IgE (mtIgE)>=100 IU/ml were significantly correlated with CbIgE>=0.35 IU/ml or CbIgE>=0.5 IU/ml. CBAhR in a random subsample and CbIgE levels were significantly higher in infants with rs2066853GG genotype. We suggest that infant AhR rs2066853 and their interactions with mtIgE>=100 IU/ml significantly correlate with elevated CbIgE, but AhRR and ARNT polymorphisms do not.

Effects of Baduanjin Qigong in Individuals With Schizophrenia: A Preliminary Quasi-Experimental Pilot Study.

The current quasi-experimental study explored the effects of Baduanjin qigong on body mass index (BMI) and five metabolic indexes in people with schizophrenia. Inclusion criteria were body mass index >25 kg/m2 or metabolic syndrome. Twenty-two service users were recruited from a psychiatric center and were assigned to the experimental group (EG) or control group (CG) using blocked randomization. The EG performed Baduanjin qigong lasting 1 hour for 12 weeks three times per week, whereas the CG received routine care. Generalized estimating equations showed that the EG achieved a greater decrease in BMI and waist circumference (WC) than the CG post-intervention. Baduanjin qigong may provide an effective nonpharmacological approach to reducing BMI and WC in people with schizophrenia. This study showed that performing Baduanjin qigong for 12 weeks is a feasible and effective strategy for improving the body shape of individuals with chronic schizophrenia, thus providing results that can serve as a reference for health professionals working in psychiatry departments.

Effect of an Anti-Stigma Program on Self-Stigma for Chinese Individuals With Schizophrenia: A Pilot Study With a Quasi-Experimental Design.

The current study explored the effectiveness of an anti-stigma group program for people with schizophrenia. Thirty-four participants recruited from a psychiatric day hospital were allocated to the experimental group (EG) or control group (CG). The Internalized Stigma of Mental Illness Scale (ISMIS), Perceived Psychiatric Stigma Scale (PPSS), and Beck Depression Inventory-II (BDI-II) were used to measure outcomes, which were evaluated at baseline, immediately post program, and 3-month follow up. Generalized estimating equations showed that the EG attained a greater reduction in the stigma resistance subscale of the ISMIS than the CG at posttest and 3-month follow up. Scores on the self-deprecation subscales (p = 0.025) and concerns about marital preclusion (p = 0.037) on the PPSS and BDI-II (p = 0.027) in the EG showed significant improvement over those of the CG at 3-month follow up. The anti-stigma group program seems to be effective in reducing self-stigma and depressive symptoms in people with schizophrenia.

Sleep quality mediates the relationship between lower urinary tract symptoms and health-related quality of life in women with type-II diabetes.

AIM: To examine the mediating effect of sleep quality on the relationship between lower urinary tract symptoms and health-related quality of life in women with type-II diabetes. DESIGN: A cross-sectional study. METHODS: A study questionnaire comprising three valid instruments was used to obtain data about lower urinary tract symptoms, sleep quality and physical and mental component summary health-related quality of life between July 2017 and December 2018 (n = 343). Pearson's correlation coefficients were estimated initially to examine the relationships between the three variables. Multiple regression models were tested using a regression-based approach Hayes PROCESS macro for SPSS to examine the significance of proposed mediation effects. RESULTS: Most participants experienced at least one urinary symptom (n = 268, 78.1%). The total number of types of lower urinary tract symptoms experienced by participants was significantly inversely correlated with physical and mental component summary health-related quality of life, and sleep quality. Participants' sleep quality was significantly correlated with physical and mental component summary health-related quality of life. The relationships of lower urinary tract symptoms with physical and mental component summary health-related quality of life were, respectively, fully and partially mediated by sleep quality. CONCLUSION: Sleep quality played a mediating role on the relationship between lower urinary tract symptoms and health-related quality of life. Our findings could lead to improvements of diabetes care in nursing and healthcare practices. IMPACT: Understanding the role of sleep quality in the adverse effects of lower urinary tract symptoms on health-related quality of life contributes to the development and delivery of appropriate strategies to promote optimal health-related quality of life. We recommended including assessments of lower urinary tract symptoms, sleep and health-related quality of life in routine diabetes management. Nurses and healthcare professionals should concurrently reduce lower urinary tract symptoms and improve sleep to achieve this population's optimal health-related quality of life. PATIENTS OR PUBLIC CONTRIBUTION: We recruited a sample of older women with type-II diabetes at the endocrinology and metabolism outpatient departments of two hospitals. Study participants provided responses on the study questionnaires. The two hospitals provided needed supports (e.g., height/weight scales, suitable places for interview) during the data collection process.

The association of social support and hope with self-stigma and perceived recovery among people with schizophrenia: The serial mediation effect.

BACKGROUND: It is essential to assist individuals with a mental illness who have achieved clinical recovery in their personal recovery. Understanding the relationship between self-stigma and social support and the effects on perceived recovery can be valuable for clinical professionals in helping patients lead meaningful lives. AIM: To examine the serial mediating roles of social support and perceived hope in self-stigma and the effects on perceived recovery. DESIGN: A cross-sectional study. METHODS: The study was conducted from September 2019 to June 2020. One hundred and fifty-seven patients with schizophrenia in seven chronic rehabilitation wards were enrolled. Each patient had a Positive and Negative Syndrome Scale score ≤ 60 points, and they regularly participated in occupational rehabilitation. Research tools included demographic data, the Internalized Stigma of Mental Illness Scale (ISMIS), Multidimensional Scale of Perceived Social Support (MSPSS), Herth Hope Index (HHI), and Perceived Recovery Inventory (PRI). IBM SPSS 24.0 was used to analyse the data. Pearson correlation was used to analyse the relationships between variables, and models 4 and 6 of PROCESS macro V3.4 for SPSS were used to examine the mediation model. RESULTS: The results indicated that self-stigma and perceived recovery in patients with schizophrenia are negatively correlated, that peer support and perceived hope mediate the relationship between them, and that peer support and perceived hope also have a statistically significant serial mediating effect. CONCLUSION: The serial mediation effect of peer support and perceived hope on the relationship between self-stigma and perceived recovery was statistically significant in this study. IMPACT: This research delves into strategies to assist psychiatric patients in reducing self-stigma and achieving recovery. The findings underscore the heightened significance of peer support for patients in rehabilitative wards and offer valuable insights for medical staff. REPORTING METHOD: STROBE checklist. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Narrative enhancement and cognitive therapy for perceived stigma of chronic schizophrenia: A multicenter randomized controlled trial study.

This study explored the effects of NECT on self-stigma among people with schizophrenia. Eighty-six participants were recruited and assigned to two groups. The NECT group received 20-session group meetings, while the control group received routine care. Self-stigma was measured by Internalized Stigma of Mental Illness Scale (ISMIS) and Discrimination and Stigma Scale (DISC). Generalized estimating equations were employed to explore the intervention's effectiveness. The NECT group showed a significant reduction in ISMIS total scores after 20 sessions and Stopping Self subscale scores of DISC decreased over time. The intervention is effective for improving self-stigma in people with schizophrenia.

Healthcare needs and Quality of Life in Youths with Congenital Heart Disease: Health-Promoting Behaviors as a Mediator.

PURPOSE: The aims of this study were to examine the relationship between healthcare needs, health-promoting behaviors and quality of life (QoL) of youths with congenital heart disease (CHD), and to determine whether health-promoting behaviors were a mediating variable. DESIGN AND METHODS: This cross-sectional descriptive study was conducted recruiting 205 youths aged 15 to 24 with either ventricular septal defect (VSD) or tetralogy of Fallot (TOF). A self-reported questionnaire was used to collect demographic information; furthermore, the thickness of the triceps skinfold was measured. The Healthcare Needs Scale for Youth with CHD, Adolescent Health Promotion-short form scale, and World Health Organization QoL-BREF scale were administered, and Pearson's correlation, multiple regressions, and the Sobel test were conducted. RESULTS: The triceps skinfold of participants with VSD was significantly thicker than that of participants with TOF (p < 0.05). Healthcare needs, health-promoting behaviors, and QoL were positively correlated. The overall health-promoting behaviors served as a partial mediator between overall healthcare needs and QoL, accounting for 40.1% of the total variation. CONCLUSIONS: The study illustrates that health-promoting behaviors have an impact on healthcare needs and QoL of youths with CHD. The development of tailored health consulting interventions to fulfill healthcare needs is required to improve physical and psychosocial wellness among youths with CHD. PRACTICE IMPLICATIONS: Targeting individual and public health strategies for enhancing health-promoting behaviors should be integrated in CHD care planning.

Association of auditory hallucination and anxiety symptoms with depressive symptoms in patients with schizophrenia: A three-month follow-up.

This study was to investigate the association of auditory hallucinations and anxiety symptoms with depressive symptoms in patients with schizophrenia for three months. The participants (N = 189) were evaluated using Characteristics of Auditory Hallucination Questionnaire (CAHQ), Beck Anxiety Inventory (BAI), and Beck Depression Inventory-II. Forty-two participants suffered from depressive symptoms at both baseline and 3-month follow-up. Higher CAHQ and BAI at both periods predicted depressive symptoms at three-month end. Being male, increased severity of CAHQ and BAI were risk factors of depressive symptoms. Psychiatric professionals must educate patients to manage auditory hallucinations and anxiety symptoms to decrease depressive symptoms.

Auditory Hallucinatory Beliefs in Patients With Schizophrenia: Association of Auditory Hallucinations With Social Interactions, Characteristics and Emotional Behaviors Over 3 Months.

The aims of this study were to explore social interactions, characteristics, and emotional behaviors to detect changes in auditory hallucinatory beliefs in patients with schizophrenia over a 3-month period. Participants (n=189) were evaluated using the Auditory Hallucinations Assessment Scale (AHAS) and the Assessment of Communication and Interaction Skills (ACIS). The characteristics and emotional behaviors measured by the AHAS showed improvements, while auditory hallucinatory beliefs became less influential. Social interaction scores increased regardless of changes in auditory hallucinatory beliefs. Psychiatric professionals need to train those who hear voices to react to them with indifference.

Health related quality of life and polychlorinated biphenyls and dibenzofurans exposure: 30 years follow-up of Yucheng cohort.

BACKGROUND: Quality of life (QOL) can be affected by diseases, disasters, and exposure events to environmental factors. However, whether health-related QOL (HRQOL) might be adversely affected by exposure to dioxin-like chemicals 30 years ago is unknown. METHODS: We studied people who were poisoned to polychlorinated biphenyls (PCBs) and dibebenzofurans (PCDFs) due to ingestion of contaminated rice oil in 1979 in central Taiwan, and were called Yucheng (oil-disease in Chinese) people. In 2008, we conducted a survey in 1305 exposed people by mailed questionnaire, which included HRQOL by World Health Organization (WHO) quality of life-BREF (WHOQOL-BREF) Taiwanese version. A total of 240 Yucheng subjects aged 18-65 years satisfactorily completed the Questionnaire. For comparison, we obtained information from the database of 2001 National Health Survey conducted by the National Health Research Institute and Bureau of Health Promotion, Department of Health, Taiwan. Data from age-, sex-, and county-matched background individuals were extracted using 1:3 match. HRQOL among Yucheng people with/without skin manifestation and unexposed referents were compared, while adjusting for other factors by multiple regression analyzes. RESULTS: The Yucheng people had significantly reduced scores in the physical, psychological, social, and environmental domains as compared to the referents. Those with skin manifestations were more severely affected than those with no skin manifestations, suggesting a dose-related effect on QOL in exposed people. CONCLUSION: We show for the very first time that poisoning due to persistent organic pollutants PCBs and PCDFs can affect QOL 30 years after the exposure, especially among those most severely poisoned.

Gestational exposure to polychlorinated biphenyls and dibenzofurans induced asymmetric hearing loss: Yucheng children study.

INTRODUCTION: In 1979, approximately 2000 people in central Taiwan were exposed to polychlorinated biphenyls and dibenzofurans (PCBs/PCDFs) due to ingestion of contaminated rice oil. The children born to mothers exposed to PCBs/PCDFs were called Yucheng children. We conducted a follow-up study to examine the association between gestational PCBs/PCDFS exposure and auditory function in Yucheng children's early adulthood. METHODS: In 1985 and early 1992, Yucheng children and their age, gender, socio-economic matched unexposed referent children were recruited for physical examination and long-term follow-ups. In 2007, Yucheng children and referent children were invited to participate in a health examination, including assessment of pure-tone air-conduction thresholds and distortion product otoacoustic emissions (DPOAEs) test. Gestational exposure to PCBs/PCDFs in Yucheng children were estimated by back-extrapolation of their mother's serum concentration to the time of childbirth. RESULTS: A total of 86 Yucheng children (51.2% males) and 97 referent children (50.5% males) were included for analysis. No difference was found in demographic characteristics between two groups. Among the Yucheng children, 53 had estimated PCBs/PCDFs concentrations. We found that Yucheng children were at higher risk of having elevated hearing threshold at low frequencies in the right ear. Estimated maternal concentrations of 2,3,4,7,8-pnCDF at the time of birth were associated with increased hearing thresholds and decreased DPOAEs amplitudes at low frequencies in the right ear. CONCLUSION: Gestational exposure to PCBs/PCDFs caused adverse asymmetrical hearing effects detectable even in early adulthood.

The effects of auditory hallucination symptom management programme for people with schizophrenia: a quasi-experimental design.

AIM: To examine the effectiveness of an auditory hallucinatory symptom management programme in patients with chronic schizophrenia. BACKGROUND: Thirty per cent of chronic schizophrenia patients are still disturbed by hallucinations, which influence their psychological and social well-being, even when they take medication regularly. METHOD: Fifty-eight people experiencing schizophrenia with auditory hallucinations from psychiatric inpatient rehabilitation wards in northern Taiwan participated in the study, with 29 in the experimental group and 29 in the control group. The experimental group received an auditory hallucinatory symptom management programme. The auditory hallucinatory symptom management programme involved 60-minute meetings once a week, for a total of 10 meetings. The control group received routine care, which included free recreation for 40 minutes and walking for 20 minutes. The participants completed three self-report questionnaires: the Beck Depressive Inventory II, the Beck Anxiety Inventory and the Characteristics of Auditory Hallucinations Questionnaire. Data were collected at baseline, immediately following the intervention and at 3 months and 6 months post intervention. Data collection occurred between March 2010-May 2013. RESULTS: The experimental group showed a non-significant improvement in anxiety symptoms over time. Generalized estimating equations revealed that the experimental group achieved a greater drop in Characteristics of Auditory Hallucinations Questionnaire score than the controls at three and 6 months post intervention. Beck Depressive Inventory II scores in the experimental group (n = 29) had significantly improved in 3 months. CONCLUSION: The auditory hallucinatory symptom management programme seems to be effective in improving auditory hallucinatory symptoms and depressive symptoms in patients with schizophrenia.

Psychometric Properties of the Chinese Version of the Gratitude at Work Scale in Employed Nurses: A Cross-Sectional Study.

BACKGROUND: The Gratitude at Work Scale, originally developed by American scholars, has been widely administered to mental health professionals and human service workers to explore gratitude in the workplace. No Chinese-language instrument is currently available for assessing workplace gratitude. PURPOSES: The aims of this study were to (a) translate the original English version of the Gratitude at Work Scale into a traditional Chinese version (TC-GAWS), confirm its factor structure, and analyze its psychometric properties among newly employed nurses and (b) develop and evaluate the psychometric properties of the TC-GAWS short form. METHODS: A psychometric study using a cross-sectional web-based design was conducted in Taiwan. Three hundred twenty-two employed nurses completed a battery of self-administered online questionnaires that included a demographic datasheet, the Gratitude Questionnaire-Six-Item Form, the Connor-Davidson Resilience Scale-10, and the Thoughts of Quitting Scale. IBM SPSS 24.0 and AMOS 28.0 were used for data analysis, and Cronbach's alpha and Pearson's correlation were used to assess reliability and concurrent validity. Exploratory factor analysis and confirmatory factor analysis (CFA) were conducted. RESULTS: The internal consistency and stability of the TC-GAWS total scale were .88 and .91, respectively. The exploratory factor analysis showed a satisfactory Kaiser-Meyer-Olkin value of .88 and a Bartlett's test value of 654.01 ( p < .001), suggesting that 64.55% of the total variance was explained by the two-factor TC-GAWS. After item reduction, the CFA of the six remaining items of the TC-GAWS short form revealed adequate fit statistics for a two-factor structure and a second-order factor. Strong correlations were found between the 10-item and six-item TC-GAWS ( r > .94) in the two samples, suggesting good concurrent validity. The overall scores for the 10-item and six-item TC-GAWS had similar convergent validity, with moderate-to-strong correlations for the Gratitude Questionnaire-Six-Item Form ( r = .45 and .540), Connor-Davidson Resilience Scale-10 ( r = .49 and .51), and Thoughts of Quitting Scale ( r = -.57 and -.53). The CFA yielded a two-factor, six-item model that exhibited good fit with the latent constructs of χ 2 / df = 11.06/8 = 1.38, p = .198, comparative fit index = .996, goodness-of-fit index = .979, root mean square error of approximation = .045, root mean square residual = .030, and standardized root mean squared residual = .023. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: Both the 10- and six-item TC-GAWS instruments demonstrated good reliability and validity in nurse participants. The TC-GAWS may be used to measure gratitude in nurses in the workplace. This instrument has the potential to facilitate a better understanding of gratitude in nurses, which may be applied to the improvement of nursing management, research, and education.

Psychometric evaluation of Suicide Management Competency Scale for nursing students: A cross-sectional study.

Suicide management skills are essential for nursing students, as they are often the initial healthcare contact for individuals at risk of suicide. Recognising signs of suicidal ideation and behaviour is critical for initiating timely interventions. This study aimed to develop and access the psychometric evaluation of the Suicide Management Competency Scale (SMCS) for nursing students. A first draft of the SMCS was initially developed following literature and focus group, and a scale containing 28 items was constructed. We recruited 216 participants from two nursing schools. Construct validity was evaluated with exploratory factor analysis (EFA). Internal consistency reliability was determined with Cronbach's alpha, and test-retest reliability was examined with intra-class correlation. After four rounds of EFA and item analysis, we reduced the number of items to 16. We deleted 12 items, including 4 items for communalities less than 0.40, 3 items for cross-loading, 3 items for factor loading less than 0.40, and 2 items for low corrected item-total correlation. The final 16-item SMCS resulted in three subscales, which explained 55.813% of the total variance: emotional challenges in suicide risk assessment, delivering suicide interventions, and suicide risk nursing competence and confidence. Cronbach's alpha was 0.854 for the total score and 0.748 to 0.847 for the subscales. The newly developed SMCS was found to have good reliability and validity, suggesting that this scale could be used to evaluate nursing students' perceived competency in managing suicide, which might help cultivate competence in nurses' ability to effectively manage and prevent suicide, thus contributing to saving lives.

Nurses' perspectives on child-friendly care needs in emergency departments: A qualitative study.

BACKGROUND: Children can become anxious when undergoing emergency medical treatment. Therefore, emergency departments should be child friendly. This study explored emergency nurses' perspectives on children's needs during emergency care. METHOD: This qualitative study employed purposive sampling to recruit 17 emergency nurses from 3 medical centers in northern and central Taiwan. Individual interviews were conducted between January and August 2021. Data were analyzed through qualitative content analysis. RESULTS: The participants had 2-23 years of experience in caring for children in emergency departments. We identified 208 unique meaning units in the interview data, 79 of which were related to child-friendly emergency care. These were classified into 42 codes across 6 categories and 27 subcategories. The six categories were timely comfort, emotional care, frontline safety, emergency response, human resources support, and treatment efficiency. CONCLUSION: Emergency nurses have professional competencies, play a crucial role as care providers for children in the emergency department, and ensure the comfort and safety of children seeking treatment. The categories related to child-friendly emergency care identified in this study can serve as a basis for developing child-friendly care emergency guidelines.

Exploring the Effectiveness of Group Cognitive Stimulation Training in People With Schizophrenia: A Randomized Controlled Trial.

BACKGROUND: Schizophrenia is a chronic degenerative brain disease. Cognitive impairment, the core symptom of this disease, affects the mood and social functioning of patients severely. Nonpharmacological therapies that both improve cognitive function and are suitable for patients with schizophrenia remain underdeveloped. PURPOSE: This article was designed to explore the effects of group cognitive stimulation training (GCST) on cognitive function and social function in people with schizophrenia. METHODS: A randomized controlled trial was conducted. The 76 participants were allocated into either the experimental or control group using blocked randomization. The participants were all patients with chronic schizophrenia recruited from seven rehabilitation units in northern Taiwan who were 20-65 years old and scored 10-25 on the Montreal Cognitive Assessment Taiwan Version. The experimental group received the 60-minute GCST twice a week for 7 weeks, whereas the control group received standard treatment. All outcome indicators were analyzed at baseline and after intervention using generalized estimating equations. The primary outcome indicators included cognitive function assessed using the Taiwan version of the Montreal Cognitive Assessment, working memory assessed using the Wechsler Memory Scale-Third Edition, and executive function assessed using the Taiwanese version of the Frontal Assessment Battery. The secondary outcome indicator was social function assessed using the Social Function Scale-Taiwan short version. RESULTS: Generalized estimating equation modeling revealed the experimental group exhibited significant improvement in Montreal Cognitive Assessment total score ( B = 1.33, SE = 0.65, p = .040) and Social Function Scale-Taiwan short version ( B = 9.55, SE = 2.38, p < .001) after adjusting for nine covariates. No significant differences between the two groups in terms of working memory ( B = 4.79, SE = 2.66, p = .071) or executive function ( B = 0.53, SE = 0.63, p = .399) were found. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The results indicate that GCST positively impacts overall cognitive and social functions but not higher-order cognitive function (working memory and executive function). In clinical settings, GCST may be applied to improve cognitive function in people with schizophrenia. The findings of this study may inform the practice of mental health nurses to improve cognitive function in patients in clinical care.

Psychosocial rehabilitation activities, empowerment, and quality of community-based life for people with schizophrenia.

Many variables influencing quality of life (QOL) for outpatients with schizophrenia have been identified from prior studies. Symptom severity, psychosocial rehabilitation activities, and empowerment have all been clearly identified as key variables. However, which variables are the most influential and important factors remains unknown; factors influencing QOL, either directly or indirectly and to what degree, need to be examined. The aim of this study was to test the hypothesis that empowerment is a possible mediator of how (a) psychiatric symptoms and (b) psychosocial rehabilitation activities affect QOL for outpatients with schizophrenia in the community. We used the probability proportional to size random sampling for 190 outpatients with schizophrenia at 10 community rehabilitation centers in Taipei, such that samples consisted of adults who fulfilled the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria. The instruments included the questionnaire to gather demographic and disease information, the Empowerment Scale, the Psychiatric Symptoms Scale, the psychosocial rehabilitation activity (PRA), and the Quality of Life Scale for Psychiatric Patients. Beyond descriptive statistics, correlation and structural equation models were computed. Findings showed that empowerment in outpatients with schizophrenia mediates QOL, whereas psychosocial rehabilitation activities seem to increase empowerment, which may in turn increase QOL. Psychotic symptoms seem to have a direct effect of decreasing QOL that could not be mediated by empowerment. Empowerment had a significant effect on QOL for outpatients with schizophrenia. The findings of this study support the importance of empowerment and rehabilitation activities for promoting QOL among community outpatients. We suggest that various rehabilitation programs and empowerment health education are needed to enhance QOL for schizophrenia outpatients in the community.

Menstrual effects among women exposed to polychlorinated biphenyls and dibenzofurans.

BACKGROUND: Polychlorinated biphenyls (PCBs), dibenzofurans (PCDFs), and dibenzo-dioxins (PCDDs) may affect the female reproductive system in humans. A mass poisoning occurred in Taiwan due to PCBs/PCDFs-contaminated cooking oil, and was called the Yucheng (oil-disease in Chinese). We aimed to determine whether Yucheng women were affected in their menstruation. METHODS: After the event, we followed the exposed individuals and an age-matched neighborhood reference group. Menstrual cycle characteristics and age at menarche were obtained by a telephone interview. We used multiple linear and logistic regression to examine the association between PCBs/PCDFs and menstrual cycle characteristics, after adjusting for confounding factors. RESULTS: Totally 445 women responded satisfactorily and were included in the analyses of menstrual characteristics. Menstrual cycle irregularity and dysmenorrheal did not differ between Yucheng and referents. Yucheng women's menstrual cycles were 0.5 (95% CI: 0.0-0.5; p=0.03) days shorter than those of the referents. The Yucheng women with skin lesions caused by PCBs/PCDFs were more prominently affected, with the cycles 1.2 days shorter than the referents. Yucheng women exposed to PCBs/PCDFs at the premenacheal period had reduced cycle length (-0.7 day, 95% CI: -1.4 to 0.0; p=0.04) and longer days of menstrual flow (0.5 day, 95% CI: 0.0-1.0; p=0.04). Among those women who were exposed at an age of 5-9 years, menarche started slightly earlier with borderline significance. CONCLUSIONS: Shorter menstrual cycle length and a longer duration of bleeding in each cycle were found among women previously exposed to PCBs/PCDFs. These effects were more obviously observed among those exposed at premenarcheal ages.
