Child-Mother Agreement on Experiences of School Bullying Involvement in Children With ADHD.

Objective: To examine the levels of agreement between the reports of 452 children and their mothers on children's experiences of bullying involvement at school and investigate the factors influencing the levels of agreement in children with ADHD. Method: The levels of agreement between children's and mothers' reports were examined. The influence of age, sex, ADHD symptoms, and psychiatric comorbidities on the levels of agreement was also examined. Results: The results indicated low agreement on the experiences of bullying involvement in child-mother ADHD dyads. Age and hyperactivity-impulsivity, oppositional, depressive, and anxiety symptoms significantly influenced the levels of agreement on the victimization of physical bullying. Age significantly influenced the levels of agreement on the perpetration of physical bullying. Conclusion: Multiple sources of information are required when clinicians assess the experiences of bullying involvement at school in children with ADHD. The factors influencing the levels of agreement should be considered.

Persistent and multisite homophobic harassment during childhood and adolescence and its association with school difficulties in gay and bisexual men in Taiwan

Abstract Background: Homophobic harassment can compromise mental health of sexual minority youths. Objectives: This study examined the rates of persistent and multisite homophobic harassment and their associations with school difficulties during childhood and adolescence among gay and bisexual men in Taiwan. Methods: Participants were recruited through advertisements on the Facebook, Bulletin Board Systems, and the home pages of health promotion and counseling centers for the gay, lesbian, and bisexual community. The experiences of traditional and cyber harassment based on gender role nonconformity and sexual orientation of 500 gay or bisexual men were examined. The associations of multisite and persistent harassment victimization with school difficulties were evaluated. Results: A total of 239 (47.8%) and 131 (26.2%) participants experienced persistent and multisite harassment victimization, respectively. Harassment victimization was significantly associated with low satisfaction with academic performance in any stage of study. Moreover, the participants who were harassed in senior high schools were more likely to miss classes or be truant than those who were not harassed. The victims of multisite harassment at senior high schools were more likely to miss classes or be truant than those of school-only harassment. Discussion: Prevention and intervention programs are warranted to reduce homophobic harassment in sexual minority youths.

Role of cytokine changes in clozapine-induced fever: A cohort prospective study.

AIM: Clozapine-associated fever is common but the specific cytokine changes and treatment durations that may cause fever remain unknown. We investigated the association between inflammatory cytokine changes and clozapine-induced fever in patients who were treated with clozapine. METHODS: Forty-three patients with schizophrenia or schizoaffective disorder, diagnosed by using the Chinese Version of the Mini International Neuropsychiatric Interview, were treated with clozapine for the first time (first-time use group, n = 22) or for more than 6 months (long-term use group, n = 21). The Positive and Negative Syndrome Scale, tympanic temperature, and levels of tumor necrosis factor-α (TNF-α), interferon-γ (INF-γ), interleukin-2 (IL-2), and interleukin-6 (IL-6) were determined at baseline and weeks 1, 2, 3, 4, and 6. A multiple linear regression with generalized estimating equation methods was used to analyze the association between the changes in the cytokine levels and clozapine-induced fever in the different groups. RESULTS: The IL-6 level changes were significantly different between the two groups (P = 0.04). In the first-time use group, the fever rate was increased (47.1%) compared with the long-term use group (5.6%, P = 0.005). Moreover, in these patients, the TNF-α, INF-γ, IL-2, and IL-6 levels were significantly (P < 0.001) different from patients who did not develop a fever. An interaction effect with the different treatment duration groups and fever development was only significant for IL-6 (P < 0.001). CONCLUSION: Patients who were treated with clozapine for the first time have an increased rate of developing a fever, and IL-6 might have a specific role in the interaction effect between treatment duration and fever development.

Prevalence and clinical correlates of flunitrazepam-related complex sleep behaviors.

AIM: Complex sleep behaviors (CSB) are often associated with the use of hypnotic drugs. This study investigated the prevalence and correlates of CSB among psychiatric patients who were given flunitrazepam. METHODS: From June 2011 to May 2012, a total of 268 psychiatric outpatients who had received flunitrazepam for at least 3 months were enrolled. Data on occurrence of CSB, demographic characteristics, flunitrazepam dosage and duration of use, psychiatric diagnoses, physical illnesses, and alcohol use were collected. Logistic regression analysis was used to examine the clinical correlates of CSB. RESULTS: Sixty-six participants (24.6%) reported experiencing CSB. Logistic regression analysis showed that a high dosage (>2 mg/day) of flunitrazepam (odds ratio [OR] = 1.941, 95% confidence interval [CI] = 1.090-3.455, P = 0.024) and alcohol use (OR = 1.948, 95%CI = 1.023-3.709, P = 0.042) were significantly associated with the occurrence of CSB. Sex, age, duration of flunitrazepam use, psychiatric diagnoses, and physical illnesses were not significantly associated with the occurrence of CSB. CONCLUSION: CSB among flunitrazepam users should be monitored routinely, especially among those receiving a high dosage who also consume alcohol.

Comparison of outcomes after 3-month methadone maintenance treatment between heroin users with and without HIV infection: a 3-month follow-up study.

BACKGROUND: The aim of this study was to compare the changes in primary (heroin use-related) and secondary (depressive symptoms and quality of life, QOL) outcome indicators of 3-month methadone maintenance treatment (MMT) between heroin users with and without HIV infection. METHODS: A total of 242 intravenous heroin-dependent individuals (30 with and 212 without HIV infection) receiving MMT were recruited. Primary (severity of heroin dependence, harm caused by heroin use and current heroin use) and secondary (depressive symptoms and QOL) outcome indicators were determined before and after receiving 3-month MMT. Changes in primary and secondary outcome indicators between the two groups were compared using mixed-model analysis. RESULTS: Heroin users both with and without HIV infection showed significant improvement in three primary outcome indicators after 3-month MMT, and there was no difference in the changes of these primary outcome indicators between the two groups. However, improvements in depressive symptoms and the physical domain of QOL among HIV-infected heroin users were poorer than in those without HIV infection. CONCLUSIONS: The results of this study indicated that heroin users with HIV infection did improve in the primary but not the secondary outcomes after 3-month MMT.

Correlates of dependence and beliefs about the use of hypnotics among zolpidem and zopiclone users.

BACKGROUND: Zolpidem and zopiclone are the two most commonly prescribed Z-drugs approved to treat insomnia. OBJECTIVES: To examine the demographic and clinical correlates of dependence and beliefs about hypnotic use among long-term zolpidem and zopiclone users in psychiatric treatment for insomnia. METHODS: A total of 392 psychiatric outpatients who received zolpidem or zopiclone treatment for at least 3 months for insomnia were studied. Participants' severity of hypnotic dependence and beliefs about the use of hypnotics to treat sleep problems were assessed. The correlation of dependence and beliefs about zolpidem and zopiclone treatment with demographic characteristics, hypnotic-using behaviors, co-use of addictive substances, and depressive symptoms were analyzed using multiple regression analysis models. RESULTS: Zolpidem users reported more severe dependence and a lower level of necessity regarding the use of hypnotics than zopiclone users did. High equivalent doses of hypnotics and long duration of use were significantly associated with severe dependence and a low level of necessity. Severe depressive symptoms were signiciantly associated with severe dependence, a low level of necessity, and a low level of concern. Educational level was also associated with the levels of concern and necessity. Conclusions/Importance: There were differences in the level of dependence and belief about hypnotic use between zolpidem and zopiclone users. The correlates of dependence and belief identified in this study can serve as the basis for prevention and intervention programs.

Severity of alprazolam dependence and associated features among long-term alprazolam users from psychiatric outpatient clinics in Taiwan.

BACKGROUND/PURPOSE: The aim of this study was to examine the correlations between the severity of alprazolam dependence and socio-demographic characteristics, the characteristics of alprazolam use, psychiatric comorbidity, and beliefs toward alprazolam use among long-term alprazolam users in Taiwan. METHODS: A total of 148 long-term alprazolam users participated in this study. The Chinese version of the Severity of Dependence Scale was used to assess participants' severity of alprazolam dependence in the preceding month. Their socio-demographic characteristics, family function characteristics, dosage of prescribed alprazolam, duration of alprazolam use, alcohol use pattern, pain reliever and cigarette use pattern, severity of depressive symptoms, psychiatric diagnosis, and belief toward alprazolam use were investigated. RESULTS: The results of multiple regression analysis indicated that a longer duration of alprazolam use, severe depressive symptoms, a high level of belief in the necessity of alprazolam treatment, and a high level of concern about the potential adverse consequences of alprazolam use were significantly associated with more severe alprazolam dependence. CONCLUSION: Doctors should closely monitor the severity of alprazolam dependence among long-term users, especially patients' levels of depression, beliefs in the necessity of alprazolam treatment, and their concerns over the adverse consequences of continued treatment with alprazolam.

Clinical correlates of zolpidem-associated complex sleep-related behaviors: age effect.

OBJECTIVE: Complex sleep-related behaviors (CSBs) are often associated with hypnotic use, especially zolpidem. The age effect on the occurrence of CSBs has not been adequately investigated. This study aimed to investigate and compare the clinical correlates of CSBs between adult and elderly subjects who were taking zolpidem. METHOD: A total of 253 adults (aged 20-55 years) and 64 elderly subjects (aged ≥ 65 years) who were administered zolpidem for at least 3 months were enrolled from psychiatric outpatient clinics from June 2011 to May 2012. The sociodemographic characteristics of the participants, the dose of zolpidem, and the occurrence of CSBs were collected. Logistic regression analysis was used to examine the clinical correlates of CSBs. RESULTS: In total, there were 62 members of the adult group (24.5%) and 11 elderly subjects (17.2%) with CSBs; however, the difference did not reach statistical significance. Logistic regression analysis showed that there was a main effect of zolpidem dose (≥ 10 mg; OR = 2.82, P = .038) and alcohol use (OR = 2.05, P = .026), but not sex or age group. There were interactive effects between age group and zolpidem dose (P = .043), indicating that a higher dose of zolpidem was associated with CSBs only in the adult group and not in the elderly group. Adults with CSBs used a higher dose of zolpidem than adults without (mean ± SD: 15.4 ± 6.8 mg vs 11.3 ± 5.7 mg), whereas elderly patients with CSBs did not use a higher dose of zolpidem than those without (12.2 ± 5.4 mg vs 11.9 ± 7.0 mg). CONCLUSIONS: A higher dose of zolpidem was correlated with CSBs only in the adult group and not in the elderly group. Future studies investigating the factors, other than dose, related to CSBs in the elderly will be performed.

Gender differences in heroin users receiving methadone maintenance therapy in Taiwan.

This study examined gender differences in heroin users who first received MMT. Compared with men, female heroin users were younger and more likely to be unemployed, to have family members using illicit substances, to initiate heroin use at a younger age, to begin MMT earlier after starting heroin use, to have methamphetamine use, to initiate methamphetamine use at a younger age, and to report a child-raising burden and a prior history of traumatic experiences. Men were more likely to have use of betel quid, and to initiate alcohol, nicotine and betel quid use at a younger age than women.

Predictors for dropping-out from methadone maintenance therapy programs among heroin users in southern Taiwan.

This study examined the methadone maintenance therapy (MMT) retention rates of heroin users in Taiwan and the predictors for dropout in the 18-month period after starting MMT. We consecutively recruited 368 intravenous heroin users receiving MMT in 2007-2008 and applied Cox proportional hazards regression analysis to determine the predictive effect of pre- and in-treatment variables on early discontinuation of MMT. The retention rate at 18 months was 32.3%. High heroin expenses, more severe harm caused by heroin use, perceived lower family support, and lower methadone dosage at 3 months after starting MMT increased the risk of dropout in the follow-up period.

Can heroin-dependent individuals benefit from a methadone maintenance treatment program before they drop out against medical advice? A 12-month follow-up study.

AIM: Little is known about whether heroin-dependent individuals receiving methadone maintenance treatment (MMT) who were discharged involuntarily and against medical advice (DAMA) get benefits before they left. The aims of this 12-month follow-up study were to examine whether the effects of MMT on depressive symptoms, heroin dependence and quality of life (QOL) are different among the non-DAMA group, the DAMA group, and the involuntarily discharged group, as well as the time effect of receiving MMT on changes in these three outcome indicators. METHOD: A total of 266 individuals receiving MMT were divided into the non-DAMA group, the DAMA group, and the involuntarily discharged group. Participants were interviewed at baseline and at 3, 6, 9, and 12 months of treatment for levels of depressive symptoms, heroin dependence and QOL. RESULTS: The levels of depressive symptoms, heroin dependence and QOL in all three groups improved after receiving MMT for 3 months and the improvement was maintained during the MMT period. There were no significant differences in the three outcome indicators among the three groups. CONCLUSION: The results support the concept that heroin-dependent individuals benefit from MMT, even if they do not want to stay in the program or drop out involuntarily.

Self-efficacy and HIV risk behaviors among heroin users in Taiwan.

OBJECTIVE: This study examined the predictors of self-efficacy in reducing risky injection behaviors among heroin users receiving methadone maintenance treatment (MMT). METHOD: The Methadone Maintenance Treatment Outcome Study was an 18-month prospective study from March 2007 to July 2008. Data collection was conducted in the substance use disorders treatment outpatient clinics of three hospitals in southern Taiwan. A total of 368 opioid-dependent heroin users (13.6% women) were interviewed at baseline and at 3-, 6-, 9-, 12-, 15- and 18-month follow-ups. The level of self-efficacy in reducing risky injection behaviors was repeatedly assessed using the Self-Efficacy Scale for HIV Risk Behaviors. Demographic and substance use characteristics, HIV serostatus, family function, depression, and pros and cons of heroin use were collected at baseline, and methadone dosage at each follow-up interview and the duration of retention in the MMT program were also recorded. RESULTS: The results of the generalized estimating equation indicated that a lower educational level, concurrent methamphetamine use, a younger age at first heroin use, a lower methadone dosage, a higher level of depression, and a shorter duration of retention in the MMT program were predictive of a lower level of self-efficacy in reducing risky injection behaviors. CONCLUSIONS: This study found that personal and MMT-related factors were predictive of a lower level of self-efficacy among heroin users receiving MMT. Programs implemented to promote a higher level of self-efficacy should be provided to heroin users in the MMT program.

Change in quality of life and its predictors in heroin users receiving methadone maintenance treatment in Taiwan: an 18-month follow-up study.

BACKGROUND: A good quality of life (QOL) is associated with successful treatment in patients with opioid dependence. Therefore, it is of clinical benefit to examine what factors can predict a change in QOL among heroin users in the course of a methadone maintenance treatment (MMT) program. OBJECTIVES: This longitudinal study aimed to examine the patterns and predictors of change in QOL among heroin users during the period of an 18-month MMT program. METHODS: A total of 368 intravenous heroin users receiving MMT in southern Taiwan between 2007 and 2008 were interviewed using the Taiwan version of the Brief Version of the World Health Organization Quality of Life Instrument (WHOQOL-BREF) at baseline and after 3, 6, 9, 12, 15, and 18 months of treatment. Demographic and substance-use characteristics, severity of heroin use, HIV serostatus, criminal record, and family function data were collected during baseline interviews. Data on methadone dosage at each follow-up point and the duration of retention in the MMT program were also collected. RESULTS: Improvement in QOL was rapid during the first 3 months after initiation of MMT and slowed beyond the 3-month point. A higher dosage of methadone predicted a better QOL. In addition, longer retention in the program may be associated with a better QOL. CONCLUSIONS: The results supported the hypothesis that, regarding QOL, heroin users can benefit rapidly and continuously from a MMT. A higher dose of methadone and longer treatment may predict improvement in QOL. SCIENTIFIC SIGNIFICANCE: Efforts are needed to amend the modifiable factors related to poor QOL for heroin users in MMT programs.

Predictors of the severity of depressive symptoms among intravenous heroin users receiving methadone maintenance treatment in Taiwan: an 18-month follow-up study.

This 18-month follow-up study examined the predictors of the severity of depressive symptoms among intravenous heroin users receiving methadone maintenance treatment (MMT) in Taiwan. The severity of depressive symptoms in 368 intravenous heroin users receiving MMT in southern Taiwan was assessed using the Center for Epidemiological Studies Depression scale at baseline and at 3, 6, 9, 12, 15, and 18 months of treatment. Demographic and substance-using characteristics, severity of heroin use, HIV serostatus, criminal record, and family function were collected during baseline interviews. Data on methadone dosage at each follow-up interview and the duration of retention in the MMT program were also collected. A generalized estimating equation was used to determine independent predictors of depressive symptoms during the 18-month period of MMT. Female gender, lack of fixed employment, severe heroin use, concurrent methamphetamine use, low family function at baseline, heroin use during the MMT, low methadone dosage, and short duration of participation in MMT predicted more severe depressive symptoms during the 18-month MMT. This study found that sociodemographic and substance-using characteristics at baseline predicted the severity of depressive symptoms among heroin users receiving MMT. Methadone dosage and MMT duration were also predictive of depression severity. The predictors found in this study can be used to identify heroin users who are at risk for depressive symptoms in the MMT program.

Quality of life and its correlates among heroin users in Taiwan.

The aims of this study were to compare the quality of life (QOL) between subjects with and without heroin use and to examine the association of QOL with sociodemographic characteristics, characteristics of heroin use, family support, and depression among heroin users at entry to a methadone maintenance treatment program. A group of 123 heroin users who visited an outpatient addiction treatment clinic in southern Taiwan for methadone maintenance treatment were recruited into this study. We also recruited 106 subjects who had never used heroin as the control group. Their QOL status was assessed by the short form of the Taiwan Version of the World Health Organization Questionnaire on Quality of Life (the WHOQOL-BREF Taiwan version). The level of QOL between subjects with and without heroin use was compared, and the correlates of QOL among heroin users were examined. Heroin users had poorer QOL than nonusers in the physical, psychological, and social relationship domains but not the environment domain of the WHOQOL-BREF after controlling for the influences of other factors. In addition, heroin users with obvious depression had poorer QOL in all four domains than those without obvious depression. Also, heroin users who perceived higher family support had better QOL in the social relationship and environment domains. Heroin users had poorer QOL than nonusers in multiple domains. Relief of depressive symptoms and enhancement of family support should be important strategies to improve QOL in heroin users.

The role of insight to alcohol use disorders in insight to schizophrenia.

The aims of this study were to examine the difference in the level of insight into schizophrenia between patients with schizophrenia with and without comorbid alcohol use disorders (AUDs) and to examine the association between insight into schizophrenia and insight into AUDs in patients with comorbid schizophrenia and AUDs. A total of 51 schizophrenic subjects with comorbid AUDs and 67 schizophrenic subjects without AUDs were recruited into this study. The Schedule of Assessment of Insight-Expanded Version and the Hanil Alcohol Insight Scale were used to measure subjects' insight into schizophrenia and AUDs, respectively. Multiple regression analysis models were used to examine the association between insight into schizophrenia and comorbid AUDs in all subjects, as well as the association between insight into schizophrenia and insight into AUDs in the subjects with comorbid schizophrenia and AUDs. The results indicated that schizophrenic subjects with comorbid AUDs had a lower level of insight into schizophrenia than those without AUDs. Meanwhile, among subjects with comorbid schizophrenia and AUDs, those who had a higher level of insight into AUDs had a higher level of insight into schizophrenia. Based on the results of this study, we suggest that evaluating comorbid AUDs and the level of insight into AUDs is important when evaluating the level of insight into schizophrenia among patients with comorbid schizophrenia and AUDs.

Comparisons of insight in schizophrenia, bipolar I disorder, and depressive disorders with and without comorbid alcohol use disorder.

AIMS: To compare the level of insight among six groups of patients with psychiatric disorders, including those with schizophrenia (SZ), bipolar I disorder (BP), or depressive disorders (DD) who had or did not have comorbid alcohol use disorder (AUD). METHODS: A total of 285 outpatients meeting the aforementioned criteria were recruited into the study. The Schedule of Assessment of Insight-Expanded version (SAI-E) was used to measure subjects' insight. Analysis of covariance (ancova) was used to compare the levels of insight among the six groups of subjects. RESULTS: Regardless of whether patients had comorbid AUD or not, patients with DD had higher levels of insight than did patients with SZ. Comorbid AUD had independent effects on the differences in the level of insight between patients with DD and BP and between patients with BP and SZ. No statistically significant difference in insight was found between patients with the same psychiatric diagnosis with and without comorbid AUD. CONCLUSIONS: In addition to psychotic features and clinical states, comorbid AUD should be taken into consideration when comparing the level of insight among patients with different psychiatric diagnoses.

Factors related to abstinence from drug use and seeking help from medical services in Taiwanese heroin and methamphetamine users.

The aim of this study was to examine the factors related to abstinence from heroin and methamphetamine (MAMP) use and to seeking help from medical services in Taiwanese drug users. A total of 196 heroin users and 226 MAMP users were recruited in this study. Their experience of previous abstinence from drug use and the routes taken to seek help for abstinence were determined at interview. Demographic data, characteristics of drug use and reasons to abstain from drug use were compared between subjects who had and those who had never tried to abstain from drug use before, as well as between the subjects who had previously sought help from medical services and those who had tried to abstain from drug use by themselves. Those who had previously tried to abstain from heroin use had longer durations of heroin use, spent more money on getting heroin, were more likely to have a criminal record of illicit drug use and had longer durations of being detained due to illicit drug use compared with those who had never tried to abstain from heroin use. Those who had sought help from medical services for abstinence were more likely to be heroin users and to spend more money on getting illicit drugs, and tried to abstain due to concerns about relationships with family. Demographic data, characteristics of drug use and reasons to abstain from drug use were different between drug users who had different experiences of abstinence.

Screening for Internet addiction: an empirical study on cut-off points for the Chen Internet Addiction Scale.

The aim of this study was to establish the optimal cut-off points of the Chen Internet Addiction Scale (CIAS), to screen for and diagnose Internet addiction among adolescents in the community by using the well-established diagnostic criteria of Internet addiction. This survey of 454 adolescents used screening (57/58) and diagnostic (63/64) cut-off points of the CIAS, a self-reported instrument, based on the results of systematic diagnostic interviews by psychiatrists. The area under the curve of the receiver operating characteristic curve revealed that CIAS has good diagnostic accuracy (89.6%). The screening cut-off point had high sensitivity (85.6%) and the diagnostic cut-off point had the highest diagnostic accuracy, classifying 87.6% of participants correctly. Accordingly, the screening point of the CIAS could provide a screening function in two-stage diagnosis, and the diagnostic point could serve as a diagnostic criterion in one-stage massive epidemiologic research.
