Validation of the Thai Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) among young adults.

BACKGROUND: The Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) is a consistent and comprehensive instrument to assess symptoms of specific internet-use disorders including those related to gaming, shopping, pornography use disorder, social networks use and gambling considering criteria in the eleventh revision of the International Classification of Diseases (ICD-11). However, to date, there is little evidence supporting instruments assessing major types of specific internet use disorders in Thailand. The aim of this present study was to assess the psychometric properties of the ACSID-11 among Thai young adults. METHODS: A total of 612 participants were recruited. A confirmatory factor analysis (CFA) examined construct validity of the ACSID-11. Cronbach's α and McDonald's ω were used to assess reliability of the ACSID-11. Pearson correlations examined relationships between ACSID-11 domains and Internet Gaming Disorder Scale-Short Form (IGDS9-SF) scores. RESULTS: The CFA supported validity of the Thai version of the ACSID-11 and a four-factor structure. Specific domains of the Thai ACSID-11, particularly gaming, were positively and significantly correlated with IGDS9-SF scores. CONCLUSIONS: Data indicate that the Thai version of the ACSID-11 is a valid and reliable instrument to assess major types of specific internet use disorders. Additional studies are needed to further examine the validity and reliability of the Thai ACSID-11.

Examining the association between neuropsychiatric symptoms among people with dementia and caregiver mental health: are caregiver burden and affiliate stigma mediators?

BACKGROUND: Neuropsychiatric disturbances are common manifestations of dementia disorders and are associated with caregiver burden and affiliate stigma. The present study investigated affiliate stigma and caregiver burden as mediators for the association between neuropsychiatric symptoms of people with dementia (PWD) and caregiver mental health such as depression and anxiety. METHODS: A cross-sectional survey study was carried out with 261 dyads of PWD and informal caregivers from the outpatient department of a general hospital in Taiwan. The survey included the Caregiver Burden Inventory (CBI), the Affiliate Stigma Scale (ASS), the Taiwanese Depression Questionnaire (TPQ), and the Beck Anxiety Inventory (BAI). Mediation models were tested using the Hayes' PROCESS macro (Model 4 for parallel mediation model; Model 6 for sequentially mediation model). RESULTS: Caregiver burden, affiliate stigma, caregiver depression, and caregiver anxiety were significantly associated with neuropsychiatric symptoms. After controlling for several potentially confounding variables, it was found that PWD's neuropsychiatric symptoms, caregiver burden and affiliate stigma significantly explained 52.34% of the variance in caregiver depression and 37.72% of the variance in caregiver anxiety. The parallel mediation model indicated a significantly indirect path from PWD's neuropsychiatric symptoms to caregiver mental health through caregiver burden and affiliate stigma, while the direct effect was not significant. Moreover, there was a directional association between caregiver burden and affiliate stigma in the sequential mediation model. CONCLUSIONS: These findings show that it is imperative to improve caregivers' perception of those with dementia to reduce internalized stigma and to improve caregivers' mental health. Implementation of affiliate stigma assessment in clinical practice would allow distinctions to be made between the impact of affiliate stigma and the consequences of caregiver burden to help inform appropriate intervention.

Quality of life and care burden among family caregivers of people with severe mental illness: mediating effects of self-esteem and psychological distress.

BACKGROUND: Family caregivers are important allies for healthcare providers in facilitating the recovery process among people with mental illness (PWMI). The present study examined the factors associated with quality of life (QoL) among family caregivers of PWMI. METHODS: A multi-center cross-sectional survey was conducted. Family caregivers of people with schizophrenia, major depressive disorder, and bipolar disorder were recruited using convenience sampling. A survey assessing their QoL, depression, anxiety, and self-esteem was completed with self-rated psychometric scales including the Rosenberg Self-Esteem Scale, Caregiver Burden Inventory, Taiwanese Depression Questionnaire, Beck Anxiety Inventory, and World Health Organization Quality of Life Instrument Short Form. A mediation model was constructed with QoL as the dependent variable, care burden as the independent variable, and psychological distress (including depression and anxiety) with self-esteem as mediating variables. RESULTS: Family caregivers of people with schizophrenia had worse QoL compared with counterparts of people with major depression and bipolar disorder. The sociodemographic of both caregivers and PWMI had less impact on QoL when psychological factors were considered. Caregivers with lower self-esteem, higher levels of psychological distress, and heavier care burdens had poorer QoL. Care burden had a significant total effect on QoL. Both self-esteem and psychological distress were significant mediators. CONCLUSION: The findings indicated that caregivers' psychological health and care burden influenced their QoL. Interventions that target family caregivers' self-esteem and psychological distress may attenuate the effect from care burden, and further improve their QoL.

A prospective study on the link between weight-related self-stigma and binge eating: Role of food addiction and psychological distress.

OBJECTIVES: This prospective study investigated the link between weight-related self-stigma and binge eating by (a) examining the temporal association between weight-related self-stigma and binge eating; (b) investigating the mediating role of food addiction in the association between weight-related self-stigma and binge eating; and (c) examining the mediating role of psychological distress in the association between weight-related self-stigma and binge eating. METHOD: Participants comprised 1,497 adolescents (mean = 15.1 years; SD = 6.0). Body mass index and weight bias were assessed at baseline; psychological distress (i.e., depression, anxiety, and stress) assessed and food addiction at 3 months; and binge eating at 6 months. The mediation model was analyzed using Model 4 in the PROCESS macro for SPSS with 10,000 bootstrapping resamples. RESULTS: There was no significant direct association between weight-related self-stigma and binge eating. However, food addiction and psychological distress significantly mediated the association between weight-related self-stigma and binge eating. DISCUSSION: These findings highlight the indirect association between weight-related self-stigma and binge eating via food addiction and psychological distress. Consequently, intervention programs targeting food addiction and psychological distress among adolescents may have significant positive effects on outcomes for weight-related self-stigma and binge eating. The findings will be beneficial to researchers and healthcare professionals working with adolescents during this critical developmental period.

Comparing Affiliate Stigma Between Family Caregivers of People With Different Severe Mental Illness in Taiwan.

The family caregivers of people with mental illness may internalize the public stereotypes into the affiliate stigma (i.e., the self-stigma of family members). This study aimed to compare the affiliate stigma across schizophrenia, bipolar disorder, and major depressive disorder, and to investigate potential factors associated with affiliate stigma. Each caregiver of family members with schizophrenia (n = 215), bipolar disorder (n = 85), and major depressive disorder (n = 159) completed the Affiliate Stigma Scale, Rosenberg Self-Esteem Scale, Caregiver Burden Inventory, Taiwanese Depression Questionnaire, and Beck Anxiety Inventory. After controlling for potential confounders, the hierarchical regression models showed that caregivers of a family member with schizophrenia had a higher level of affiliate stigma than those of bipolar disorder (ß = -0.109; p < 0.05) and major depressive disorder (ß = -0.230; p < 0.001). Self-esteem, developmental burden, and emotional burden were significant factors for affiliate stigma. The affiliate stigma of caregivers is associated with their self-esteem, caregiver burden, and by the diagnosis.

Three-year mortality rate of suicide attempters in consultation-liaison service.

OBJECTIVE: Suicide attempters might be sent to the emergency room for urgent medical intervention. Some with more severe physical morbidity may be hospitalised, and psychiatrists might be consulted for suicide evaluation. The aim of our study was to investigate the three-year all-cause mortality rate of hospitalised suicide attempters with regard to the effect of consultation-liaison services, and to identify any risk factors associated with mortality. METHODS: Between 2002 and 2006, 196 inpatients from medical or surgical wards in a general hospital who had consulted psychiatrists because of suicide attempts were collected consecutively. We traced their mortality incidence during a three-year period, and calculated the mortality rate and time (days) to death. RESULTS: Three-year all-cause mortality was 20.4%, and there was a higher risk of mortality in the first two years after the index suicide attempt. In the adjusted Cox regression model, associated risks included male gender, older age, diagnosis of depressive disorders and lack of psychiatric follow-up. CONCLUSIONS: We found that hospitalised suicide attempters had higher all-cause mortality after discharge, and determined that psychiatric follow-up is helpful. More attention should be paid to those with potential risk factors, and timely intervention is suggested in order to reduce mortality.

The Role of Alexithymia in the Incidence of Poststroke Depression.

Poststroke depression (PSD) is the most frequent neuropsychiatric consequence of stroke, and alexithymia is a construct characterized by the inability to identify and describe emotions. Our study aimed to determine whether alexithymia is a risk factor for the development of PSD. Patients with ischemic stroke admitted to a general teaching hospital were enrolled in this 6-month study. The patients were evaluated with the Toronto Alexithymia Scale-20 (TAS-20), Beck Anxiety Inventory (BAI), National Institute of Health Stroke Scale (NIHHS), and Mini-Mental Status Examination at baseline and then followed up each month for detection of PSD using the Center for Epidemiologic Studies of Depression scale. In all, 285 patients with ischemic stroke were enrolled, and 93.3% completed the 6-month study. The overall incidence of PSD within 6 months was 16.5%. In multivariate regression analyses, the incidence of PSD was significantly associated with higher BAI, higher NIHSS, and higher TAS-20 scores. In conclusion, our study highlights the importance of alexithymic symptoms as a risk factor for PSD.

Problematic smartphone use and two types of problematic use of the internet and self-stigma among people with substance use disorders.

BACKGROUND AND AIMS: Guided by the Interaction of Person-Affect-Cognition-Execution (I-PACE) model and a self-stigma framework, this study aimed to investigate relationships between cognitive and affective self-stigma and behavioral self-stigma, problematic use of internet (PUI), and problematic smartphone use (PSU) among people with substance use disorders (SUDs). It also examined mediating roles for affective self-stigma in the relationships between cognitive self-stigma and behavioral self-stigma/PUI/PSU. METHODS: Using a cross-sectional design, 530 participants diagnosed with SUDs in Taiwan were recruited from a psychiatric center in Taiwan. Mediation models were investigated using the Hayes' Process Macro Model 4. RESULTS: Mediation analyses indicated that cognitive self-stigma was directly associated with behavioral self-stigma (p < 0.001), but not with either types of PUI or PSU (p-values ranging from 0.41 to 0.76). Affective self-stigma was directly related to behavioral self-stigma (p < 0.001), two types of PUI, and PSU (ß = 0.24-0.30; all p < 0.001); cognitive self-stigma was indirectly associated with behavioral self-stigma (ß = 0.53; 95  % bootstrapping CI = 0.46, 0.60), two types of PUI, and PSU (ß = 0.20-0.25; 95  % bootstrapping CI = 0.08-0.14, 0.31-0.37) via a mediating effect of affective self-stigma. DISCUSSION AND CONCLUSION: Findings support the I-PACE model in a self-stigma context. The findings also suggest that addressing affective self-stigma may help prevent or reduce behavioral self-stigma, PUI, and PSU among people with SUDs. Longitudinal studies are warranted to investigate over time relationships between self-stigma and PUI/PSU in people with SUDs.

Neonatal and pregnancy complications following maternal depression or antidepressant exposure: A population-based, retrospective birth cohort study.

OBJECTIVES: Depression is common during pregnancy, and antidepressants are often prescribed for treatment. However, depression and antidepressant use both increase the risk of neonatal and pregnancy complications. To separately evaluate the effects of antidepressant use and the underlying depression on pregnancy and neonatal complications by using a robust statistical method to control for confounding by indication. METHODS: All study data were obtained from Taiwan's National Health Insurance Research Database. Pregnant women were divided into three groups: those with no depression and no antidepressant exposure(n = 1619,198), depression and no antidepressant exposure(n = 2006), and depression and antidepressant exposure(n = 7857). Antidepressant exposure was further divided into that before pregnancy and during each trimester. RESULTS: Mothers with depression but no antidepressant exposure exhibited increased risks of intrauterine growth restriction and preterm delivery, compared with mothers without depression. In mothers with depression, antidepressant exposure before pregnancy or during the first trimester conferred increased risks of gestational diabetes mellitus, malpresentation, preterm delivery and cardiovascular anomalies, compared with no antidepressant exposure. Moreover, antidepressant exposure during the second or third trimester conferred increased risks of anemia, a low Apgar score, preterm delivery and genitourinary defects. However, antidepressants administered before pregnancy and during all trimesters did not increase the risk of stillbirth. CONCLUSION: Depression and antidepressant treatment for depression during pregnancy may individually increase the risks of some neonatal and pregnancy complications. Physicians should thoroughly consider the risks and benefits for both the mother and fetus when treating depression during pregnancy by using antidepressants.

One-year mortality of elderly inpatients with delirium, dementia, or depression seen by a consultation-liaison service.

BACKGROUND: Delirium, dementia and depression are the most prevalent mental disorders in elderly patients, and are associated with higher mortality. OBJECTIVE: The purpose of this study was to assess 1-year mortality among elderly patients with delirium, dementia, or depression seen by a psychiatry consultation-liaison service in a general hospital. METHODS: We consecutively enrolled inpatients 65 years of age and older who were referred for psychiatric consultation (n = 614) from 2002 to 2006: 172 were diagnosed with delirium, 92 with dementia, and 165 with depression. The 1-year mortality rates for the three groups of patients were compared by log-rank test. Logistic regression analysis was used to identify any possible factors associated with mortality. RESULTS: One-year mortality was significantly higher in the delirium group than in the depression group (p = 0.048), but not significantly different between the delirium and dementia groups (p = 0.206), or dementia and depression groups (p = 0.676). Male patients had a higher mortality rate than female patients in the depression group (p = 0.003), but there was no gender difference in the delirium and dementia groups. Furthermore, the 1-year mortality of all patients was significantly associated with older age (p < 0.001) and length of hospital stay (p < 0.001), but not with gender difference and multiple physical comorbidities. CONCLUSION: These results suggest that elderly inpatients with delirium seen by a psychiatric consultation service have significantly higher mortality than elderly inpatients with depression, and that mortality is significantly associated with older age and length of hospital stay.

Respiratory Arousals in Patients with Very Severe Obstructive Sleep Apnea and How They Change after a Non-Framework Surgery.

Respiratory arousal is the change from a state of sleep to a state of wakefulness following an apnea or hypopnea. In patients with obstructive sleep apnea (OSA), it could have a helpful role to activate upper airway muscles and the resumption of airflow and an opposing role to contribute to greater ventilatory instability, continue cycling, and likely exacerbate OSA. Patients with very severe OSA (apnea-hypopnea index (AHI) ≥ 60 events/h) may have specific chemical (e.g., possible awake hypercapnic hypoxemia) and mechanical (e.g., restricted dilator muscles) stimuli to initiate a respiratory arousal. Little was reported about how respiratory arousal presents in this distinct subgroup, how it relates to AHI, Epworth Sleepiness Scale (ESS), body mass index (BMI), and oxygen saturation, and how a non-framework surgery may change it. Here, in 27 patients with very severe OSA, we show respiratory arousal index was correlated with each of AHI, mean oxyhemoglobin saturation of pulse oximetry (SpO2), mean desaturation, and desaturation index, but not in BMI or ESS. The mean (53.5 events/h) was higher than other reports with less severe OSAs in the literature. The respiratory arousal index can be reduced by about half (45.3%) after a non-framework multilevel surgery in these patients.

Negative impact of the hypopnea index or duration increase after a non-frame work surgery in patients with very severe obstructive sleep apnea.

A non-framework surgery could change the postoperative components of breathing disturbances and increase the frequency or duration of hypopnea in patients with very severe obstructive sleep apnea (OSA). Either an increase of hypopnea index, which increases apnea-hypopnea index (AHI), or an increase of its duration raises the concern of worsening the oxygen desaturation and so morbidity and mortality associated with OSA. It is unclear how the oxygen saturation would change in those having increased frequency or duration of hypopneas after the surgery. Here in 17 patients with AHI ≥ 60 events/h, having increased frequency or duration of hypopneas after the non-framework surgery, the results show that the surgery improved oxygen saturation by reducing obstructive-apnea index (36.1 events/h) and duration (8.6 s/event), despite it increased hypopnea index (16.8 events/h) and duration (9.8 s/event). The surgery improved the average of the mean oxyhemoglobin saturation of pulse oximetry (SpO2) by 2.8% (toward a ceiling mean of 94.3%), mean minimal SpO2 by 7.5%, and mean desaturation by 5%. The results suggest sufficient apnea reduction and shift from apnea to hypopnea may mask the negative impact of the increase of hypopnea index or duration and improve postoperative mean SpO2, minimal SpO2, and mean desaturation.

Change in accuracy of recognizing psychiatric disorders by non-psychiatric physicians: five-year data from a psychiatric consultation-liaison service.

AIM: Psychiatric disorders are easily underestimated and under-recognized by physicians. The aim of the present study was to investigate the change in accuracy of recognizing psychiatric symptoms. METHODS: Consecutive 5-year consultation-liaison data were collected and patients with one of the five common psychiatric diagnoses, including depressive disorders, substance use disorders, delirium, anxiety disorders and psychotic disorders, were chosen for analysis. The primary care physician's initial impression of a psychiatric diagnosis was recorded based on their reason for referral on the referral sheets. Accurate recognition was defined as matching of the physician's initial impression with the psychiatrist's final diagnosis. Mentioning the core symptoms of psychiatric diagnostic criteria or common synonyms would be considered as correct recognition. RESULTS: The overall accuracy of recognition was 41.5% and there was no significant change during this 5-year period. Substance use disorders were the one diagnosis with the highest agreement, followed by delirium, depressive disorders, anxiety disorders, and psychotic disorders. As for the factors associated with accurate recognition, male patients or those with multiple physical illnesses were more likely to have their psychiatric symptoms recognized correctly. CONCLUSIONS: Without comprehensive postgraduate psychiatric education, the accuracy of recognizing psychiatric symptoms does not improve year by year. Education should focus on common psychiatric problems among medical inpatients, especially those easily misdiagnosed, such as depression and delirium.

Association Between Family Caregiver Burden and Affiliate Stigma in the Families of People with Dementia.

Family caregivers of people with dementia (PWD) have a heavy care burden. Affiliate stigma is the stigma internalized by individuals associated with PWD. Limited research has addressed the affiliate stigma among caregivers of PWD and its influence on caregiver burden. Thus, our study investigated the burden of caregivers of PWD and its relationship with affiliate stigma. In addition, we examined the factors related to affiliate stigma. This cross-sectional study was conducted in a general hospital in Taiwan. We recruited 270 PWD and their family caregivers from the outpatient department. Relevant demographic and clinical assessment data of the patients and caregivers were evaluated. Regression analysis was performed to examine the factors associated with affiliate stigma. In total, 23.7% of the family caregivers had depression and 37.4% had anxiety. Male caregivers had higher levels of anxiety and heavier care burdens related to affiliate stigma compared with female caregivers. Moreover, characteristics such as younger age and low levels of dependence in daily activities among PWD were associated with increased affiliate stigma. A higher family caregiver burden was related to more severe affiliate stigma. Interventions for decreasing the family caregiver burden might reduce the effect of affiliate stigma.

Risk of incident dementia in late-life depression treated with antidepressants: A nationwide population cohort study.

BACKGROUND: Antidepressants are frequently used to treat depression in patients with dementia. In addition, late-life depression is associated with the incidence of subsequent cognitive impairment or dementia. However, the association between exposure to antidepressants in late-life depression and the development of incident dementia remains understudied. METHODS: Through a population-based retrospective cohort design, data were extracted from the Taiwan National Health Insurance Research Dataset of medical claims registered from 1998-2013. We collected data of individuals who had received a new diagnosis of depression between 2000 and 2007. We excluded those who received a diagnosis of depression and were given antidepressants before 2000 and those younger than 60 years. The primary outcome was the occurrence of incident dementia. The time from the prescription of antidepressants or the diagnosis of depression until the outcome or the end of 2013 was calculated as the time to event. A total of 563,918 cases were included and were divided into either antidepressant users or antidepressant nonusers. Cox proportional hazards models were used to calculate the hazard ratio and 95% confidence interval. RESULTS: Exposure to antidepressants did not increase the risk of dementia in patients with late-life depression at either a low exposure dosage (hazard ratio: 1.06, 95% confidence interval: 0.91-1.23) or a high exposure dosage (hazard ratio: 1.07, 95% confidence interval: 0.95-1.20). To confirm the validity of our results, we performed a sensitivity analysis and subgroup analysis, and the post-hoc results were consistent with the main results. CONCLUSION: Antidepressants did not increase the risk of incident dementia in patients with late-life depression.

Comparing generalized and specific problematic smartphone/internet use: Longitudinal relationships between smartphone application-based addiction and social media addiction and psychological distress.

BACKGROUND AND AIMS: The literature has proposed two types of problematic smartphone/internet use: generalized problematic use and specific problematic use. However, longitudinal findings on the associations between the two types of problematic use and psychological distress are lacking among East-Asians. The present study examined temporal associations between both generalized and specific problematic use of the smartphone/internet, and psychological distress. METHODS: Hong Kong University students (N = 308; 100 males; mean age = 23.75 years; SD ± 5.15) were recruited with follow-ups at three, six, and nine months after baseline assessment. All participants completed the Smartphone Application-Based Addiction Scale (for generalized problematic smartphone/internet use), the Bergen Social Media Addiction Scale (for specific problematic smartphone/internet use), and the Hospital Anxiety and Depression Scale (for psychological distress) in each assessment. Latent growth modeling (LGM) was constructed to understand temporal associations between generalized/specific problematic use and psychological distress. RESULTS: The LGM suggested that the intercept of generalized problematic use was significantly associated with the intercept of psychological distress (standardized coefficient [ß] = 0.32; P < 0.01). The growth of generalized problematic use was significantly associated with the growth of psychological distress (ß = 0.51; P < 0.01). Moreover, the intercept of specific problematic use was significantly associated with the intercept of psychological distress (ß = 0.28; P < 0.01) and the growth of psychological distress (ß = 0.37; P < 0.01). CONCLUSION: The initial level of problematic use of smartphone/internet increased the psychological distress among university students. Helping young adults address problematic use of the smartphone/internet may prevent psychological distress.

Development of the Family Stigma Stress Scale (FSSS) for Detecting Stigma Stress in Caregivers of People With Mental Illness.

People with mental illness and their family caregivers often perceive public stigma, which may lead to stigma-related stress (or stigma stress). However, no instruments have been developed to measure this stress for family caregivers of people with mental illness. We modified an instrument that measures the stigma stress of people with mental illness (i.e., the cognitive appraisal of stigma as a stressor) and examined the psychometric properties of the scores of the newly developed instrument: the Family Stigma Stress Scale (FSSS). Primary family caregivers of people with mental illness in Southern Taiwan ( n = 300; mean age = 53.08 ± 13.80; 136 males) completed the FSSS. An exploratory factor analysis showed that the FSSS score had two factors; both factor scores had excellent internal consistency (α = .913 and .814) and adequate test-retest reliability ( r = .627 and .533; n = 197). Significant correlations between FSSS factor scores and other instruments supported its concurrent validity and the ability of the FSSS to differentiate between clinical characteristics, for example, having been previously hospitalized or not. The FSSS is a brief and effective measure of the stigma stress of family caregivers of people with mental illness.

Antidepressant treatment and mortality risk in patients with dementia and depression: a nationwide population cohort study in Taiwan.

BACKGROUND: Dementia prevalence is increasing worldwide, and dementia is frequently comorbid with depression during its disease course. Additionally, safety concerns are rising regarding the prescription of psychotropic agents to patients with dementia. Thus, our study assessed the influence of prescribing antidepressants in dementia with depression on mortality risk, and the differences between classes of antidepressants. METHODS: This study was a population-based retrospective cohort study that utilized the National Health Insurance (NHI) medical claims data on mental illness in Taiwan between 1998 and 2013. We identified 25,890 cases of newly diagnosed dementia with depression and divided them into two groups: antidepressant users and nonusers. All-cause mortality between the two groups and the effects of different antidepressants were analyzed. RESULTS: Antidepressants reduced all-cause mortality in patients with dementia and depression after adjusting for all covariates. Furthermore, the effect was significant when antidepressant exposure was more than 168 cumulative defined daily dosages, and most classes of antidepressants had this protective effect. CONCLUSIONS: Antidepressant treatment showed significant protective effects in all-cause mortality for patients with dementia and depression. Most classes of antidepressants were effective, especially with longer treatment duration or higher dosage.

Correlations And Correlates Of Post-Traumatic Growth And Post-Traumatic Stress Symptoms In Patients With Breast Cancer.

PURPOSE: Although post-traumatic growth (PTG) and post-traumatic stress symptoms (PTSS) might develop and coexist after a major trauma, few studies have simultaneously examined them in patients with breast cancer. This study investigated the correlation between PTG and PTSS and their differential correlates in patients with breast cancer. PATIENTS AND METHODS: Overall, 145 patients with breast cancer were recruited. PTG and PTSS were assessed using the PTG inventory and the Chinese version of startle, physiological arousal, anger, and numbness, respectively. We investigated the effects of demographics, chemotherapy, depression, family support, alexithymia, and anxiety symptoms on PTG and PTSS. Multivariate linear regression analyses were performed to select the independent correlates of PTSS and PTG. RESULT: An association was observed between PTG and PTSS (r = 0.21). Based on multiple regression models, the common correlate of PTG (ß = 0.271) and PTSS (ß = 0.212) was anxiety symptoms. Differential independent correlates were years of education (ß = 0.272), receiving chemotherapy (ß = 0.248), and family support (ß = 0.259) for PTG, and chronic pain (ß = 0.316) and poor cognition (ß = -0.350) for PTSS. CONCLUSION: Differential correlates were observed for PTG and PTSS in patients with breast cancer. Possible mechanisms and relationships between PTG and PTSS were discussed.

Perceived stigma of caregivers: Psychometric evaluation for Devaluation of Consumer Families Scale.

Background/Objective: The Devaluation of Consumer Families Scale (DCFS) is commonly used to measure perceived stigma towards family members of people with mental illness. However, its factorial structure has never been confirmed using confirmatory factor analysis (CFA). This study aimed to test the psychometric properties of the DCFS Taiwan version (DCFS-TW). Method: Family caregivers (N=511) completed the DCFS-TW (97 completed the DCFS again after 2 to 4 weeks) and other instruments. CFA, test-retest reliability, internal consistency, concurrent validity, and known-group validity were analyzed. Results: The three-factor structure of the DCFS-TW performed better than the one-factor structure. Test-retest reliability (r = .66) and internal consistency were satisfactory (α = .85); concurrent validity (absolute r = .20 to .58) was acceptable; known-group validity was supported by the significantly different DCFS-TW scores in clinical characteristics (had been vs. had not been hospitalized; had been vs. had not been compulsorily admitted). Conclusions: The DCFS-TW has decent psychometric properties and is suitable for health professionals to measure perceived stigma towards family members of people with mental illness.

Antecedentes/Objetivo: La Devaluation of Consumer Families Scale (DCFS) se usa comúnmente para medir el estigma percibido de los familiares de las personas con enfermedad mental. Sin embargo, su estructura factorial nunca ha sido confirmada mediante análisis factorial confirmatorio (AFC). El objetivo de este estudio era evaluar las propiedades psicométricas de la versión taiwanesa de la DCFS (DCFS-TW). Método: Los cuidadores familiares (N=511) completaron la DCFS-TW (97 de ellos completaron nuevamente la DCFS entre 2 y 4 semanas después) y otros instrumentos. El AFC, la fiabilidad test-retest, la consistencia interna, la validez concurrente y la validez de grupos conocidos fueron analizados. Resultados: La estructura de tres factores de la DCFS-TW ajustó mejor que la estructura unifactorial. La fiabilidad test-retest (r = .66) y la consistencia interna fueron satisfactorias (α = .85); la validez concurrente (absoluta r = .20 a .58) fue aceptable, la validez de grupos conocidos fue corroborada por las puntuaciones significativamente diferentes de la DCFS-TW en relación a las características clínicas (habían vs. no habían sido hospitalizados; habían vs. no habían sido internados obligatoriamente). Conclusiones: La DCFS-TW tiene propiedades psicométricas aceptables y es adecuada para que los profesionales de la salud midan el estigma percibido en los familiares de las personas con enfermedad mental.
