The research also assessed the weekly frequency of the acquired WSE skills being expressed in daily life without accompanying irritability.</p> <p><strong>Methods:</strong> Conducted between May 1 and August 31, 2021, the research employed a purposive sampling approach, A - B model, within a single-subject design, involving 5 cases. Participants were KwASD aged 5 - 7 years from the Khon Kaen University Autistic Center. Ethical approval was obtained from the Human Research Ethics Committee at Khon Kaen University (HE643074). Research instruments included 1) a board game developed by the authors, emphasis on learning through social and experiential learning theory to impart each of WSE skills, underwent evaluation and approval by 3 experts in teaching and nursing KwASD and resulted in an item objective congruence (IOC) ranging from 0.67 to 1 for each assessment item; 2) An assessment form to appraise the weekly frequency of expression of the learned WSE without irritability, and underwent evaluation by the same expert panel, yielding IOC from 0.67 to 1 for each assessment item; and 3) a demographic data collection form. Statistical analysis involved enumerating item numbers, analyzing raw data changes, and creating single-subject design and baseline trend graphs using Microsoft Excel.</p> <p><strong>Results:</strong> Following structured teaching sessions with the board game, centered around events requiring WSE expression, all KwASD participants demonstrated increased expression of WSE in daily life, with reduced irritability compared to pre-learning levels. Subsequent teaching sessions consistently elevated all WSE scores above the baseline trend.</p> <p><strong>Conclusion:</strong> The findings suggested that a board game can effectively serve as a tool for instructing KwASD in acquiring and applying social skills, specifically focusing on waiting, sharing, and emotional self-control.</p> 2024-06-20T00:00:00+07:00 Copyright (c) 2024 Journal of the Psychiatric Association of Thailand https://he01.tci-thaijo.org/index.php/JPAT/article/view/267534 Prevalence and Associated Factors of Emotional and Behavioral Problems During COVID-19 Pandemic in Children and Adolescents with Autism Spectrum Disorder 2023-12-20T15:40:00+07:00 Warisa Chulasen warisa.chulasen@gmail.com Tikumporn Hosiri tikumporn.hos@mahidol.ac.th Napat Sittanomai napat.sittanomai@gmail.com <p><strong>Objective: </strong>To explore the prevalence and factors associated with emotional and behavioral problems among children and adolescents with autism spectrum disorder (ASD) during the COVID-19 pandemic who sought care at Siriraj Hospital from July 2022 to January 2023.</p> <p><strong>Methods:</strong> This descriptive cross-sectional study recruited children with ASD and their parents. Parents were required to complete three questionnaires; demographic data about children and their guardians, the Thai version of the Strengths and Difficulties Questionnaire (SDQ), and an assessment of the impact of the COVID-19 pandemic.</p> <p><strong>Results:</strong> The study included 167 participants. The prevalence of emotional and behavioral problems was 46.7%. Within each dimension, the prevalence rates were as follows: peer relationship problems at 85.6%, hyperactivity/inattention at 39.5%, conduct problems at 24.6%, and emotional symptoms at 15.0%. Emotional and behavioral problems were significantly associated with psychiatric comorbidities, quarantine measures affecting both children and family members due to COVID-19 risk, confirmed cases of COVID-19 among family members, disruptions to children’s daily routines, and sleep problems.</p> <p><strong>Conclusion:</strong> The prevalence of emotional and behavioral problems during the COVID-19 pandemic in children and adolescents with ASD was nearly half the total sample in the study. They may experience emotional and behavioral problems, which can be caused by both comorbidity psychiatric disorders and patient’s experiences. As such, it is important for physicians to closely monitor and assess any such issues in their ASD patients.</p> 2024-06-20T00:00:00+07:00 Copyright (c) 2024 Journal of the Psychiatric Association of Thailand https://he01.tci-thaijo.org/index.php/JPAT/article/view/268189 The Association Between Child Emotion Regulation, Child Mental Health Status, and Parental Competence in School-Aged Children in Bangkok, Thailand 2024-01-30T12:43:25+07:00 Pimprapan Ooraikul pimprapan1801@gmail.com Parichawan Chandarasiri parichawan.C@chula.ac.th Jirada Prasartpornsirichoke Jirada.pr@chula.ac.th <p><strong>Objective: </strong>This study aimed to examine the relationship between child emotion regulation, child mental health status, and parental competence in non-clinical 8 to 12-year-old children in a school in Bangkok, Thailand.</p> <p><strong>Methods: </strong>This cross-sectional study was conducted in a demonstrative school in Bangkok from March to May 2023 using an anonymous survey. Measurements consisted of demographic data, ERQ-CA/HIF for child emotion regulation, self-rated and parent-rated SDQ for child mental health status, and PSOC for parental competence. All available children aged 8 - 12 years and their primary caregivers were included, then children with neurodevelopmental disorder(s) and academic disadvantages were excluded. Parents with major psychiatric disorder(s) were also excluded. Informed consent was given, and ethical approval was granted. The relationship between factors was analyzed using Pearson's correlation. Dependent T-test, independent T-test, and one-way ANOVA were used to compare groups with different demographics.</p> <p><strong>Results: </strong>A total of 306 child-parent dyads were eligible for the study. The mean age of the children and the parents were 9.8 and 44.9 years respectively. Most of the participants had high household income and high parental education. No association between child emotion regulation and parental competence was found. However, there were weak to moderate negative associations between child emotion regulation and all psychological symptoms (r = -.19 to -.31); negative emotions and parental competence (r = -.16 to -.19); and parental competence and parent-rated psychological symptoms (r = -.12 to -.29). Weak to moderate positive associations between child emotion regulation and prosocial behaviors (r = .12 to .24) were also found, whereas negative emotions were moderately associated with emotional problems (r = .62), and weakly with all other psychological symptoms (r = .23 to .30).</p> <p><strong>Conclusion: </strong>This study found that emotion regulation is positively associated with prosocial behavior and negatively associated with mental health problems, while parental competence is associated with child's mental health outcomes, particularly prosocial behaviors and attention problems. However, no association between child emotion regulation and parental competence was found which raised an urgent question of whether parents realize their important role in coaching their child's emotion regulation. There were several limitations. More research is needed to better understand the relationship between emotion regulation, mental health, and perceived parental competence in Thai culture, with improvements for the future as suggested.</p> 2024-06-20T00:00:00+07:00 Copyright (c) 2024 Journal of the Psychiatric Association of Thailand https://he01.tci-thaijo.org/index.php/JPAT/article/view/268212 Correlation Between Smartphone Addiction and Depression in Secondary School Children 2024-01-29T10:12:01+07:00 Supapak Wilailah oootafagvah@gmail.com Siriwan Piyawattanametha siriwwa@kku.ac.th Kusalaporn Chaiudomsom kusawo@kku.ac.th Nawanant Piyavhatkul nawanant@kku.ac.th <p><strong>Objective:</strong> To study the correlation between smartphone addiction and depression in secondary school children and related factors associated with depression in secondary school children.</p> <p><strong>Method:</strong> A cross-sectional study was conducted in secondary school children.

The teacher samples were selected from various government schools, private schools, and demonstration schools. Total 437 teachers in primary and secondary classes in Thailand were tested recruited from 2020 to 2022 by Stratified sampling. Data collection happened via Google Forms platform from April 5th to April 19th, 2023. Questionnaires were used to collect the general information, factors, Generalized Anxiety Disorder; GAD7 (Thai Version) and Patient Health Questionnaire; PHQ-9 (Thai Version). The collected data was analyzed using Pearson’s Chi-Square test and Binary logistic regression. This human research study was approved and monitored by Human Research Ethics Protocol No. IPRS-IRB-2023-042</p> <p><strong>Results:</strong> The factors that significantly affected anxiety were age (<em>p</em> = 0.026), while age (<em>p</em> = 0.029) and teaching experience (<em>p</em> = 0.043) significantly affected depression. The levels of anxiety achieved (low, moderate, and severe) were 36.84%, 8.92%, and 4.58%, respectively, whereas depression achieved 22.20%, 7.78%, and 6.18%, respectively.</p> <p><strong>Conclusion:</strong> This study shows that some teachers faced and coped with mental health issues during the COVID-19 pandemic situation. School administrators and relevant agencies must plan strategies and provide interventions to assist teachers who have been experiencing anxiety and depression for the purpose of improving mental well-being. These include establishing preventive measures for potential mental health problems among teachers, such as providing school psychologists or psychiatrists to impart knowledge and counseling to teachers regarding coping mechanisms, managing expectations, and anxiety management. Additionally, annual mental health screenings for teachers should be conducted, along with organizing meetings for teachers to discuss and exchange their teaching experiences with each other in the school.</p> 2024-06-20T00:00:00+07:00 Copyright (c) 2024 Journal of the Psychiatric Association of Thailand https://he01.tci-thaijo.org/index.php/JPAT/article/view/268096 Factors Influencing Mindfulness Practice in Patients with Mild Cognitive Impairment: A Qualitative Research Study 2024-02-06T16:42:48+07:00 Nawan Rachatan nawanrachatan@gmail.com Karn Jumroonrojana karn.jum@mahidol.edu Daochompu Daochompu Nakawiro pinkstar1973@yahoo.com <p><strong>Objective:</strong> To study the factors influencing mindfulness training and suitable mindfulness practice model for patients with mild cognitive impairment (MCI)</p> <p><strong>Methods:</strong> This qualitative study included 10 participants, comprising healthcare professionals with at least 1 year of mindfulness training experience and experience treating patients with MCI (5 participants) and patients with MCI who had undergone mindfulness practice for at least 6 months at Ramathibodi Hospital (5 participants). Data was collected through semi-structured interviews, and subsequently, content analysis was employed to analyze the gathered information.</p> <p><strong>Results:</strong> Factors which promote mindfulness practice were categorized into internal and external factors. Internal factors included intention and having a positive attitude towards mindfulness, while external factors encompassed social support, suitable training methods, and a conducive environment. These factors could either support or hinder mindfulness practice. Other external factors which promoted mindfulness practice included social roles, religion, or personal beliefs. Other external factors that served as obstacles to mindfulness practice included lack of training skills, poor socioeconomic status, poor health, and fatigue from daily routines.</p> <p><strong>Conclusion: </strong>To promote mindfulness practice in individuals with MCI, encouraging a strong intention to practice mindfulness is crucial. This involves fostering a positive mindset, emphasizing the importance and benefits of mindfulness, and highlighting the control it provides over one’s behavior. Consistent and clear goal-setting for mindfulness practice is essential. Additionally, social support from friends, family, influential individuals in the community, and government support can play a significant role in motivating individuals to engage in mindfulness practice together. Creating supportive environments for mindfulness practice, simplifying and adapting mindfulness techniques to daily life, will make it more accessible for individuals with MCI, enabling them to engage in regular mindfulness practice.</p> 2024-06-20T00:00:00+07:00 Copyright (c) 2024 Journal of the Psychiatric Association of Thailand https://he01.tci-thaijo.org/index.php/JPAT/article/view/269003 The Prevalence and Associated Factors of Metabolic Syndrome in Psychiatric Patients at Thammasat University Hospital 2024-02-26T11:42:42+07:00 Nuttaya Chartchua 15nuttaya@gmail.com Winitra Nuallaong winitra145@yahoo.com Muthita Phanasathit muthita.ph@gmail.com <p><strong>Objective:</strong> To determine the prevalence and associated factors of metabolic syndrome in psychiatric patients</p> <p><strong>Methods:</strong> A descriptive cross-sectional study was conducted among psychiatric outpatients at mental health clinic, between August 1, 2022 and July 31, 2023. The sample consisted of 299 psychiatric outpatients diagnosed with the following principle disorders: psychotic disorders, bipolar disorders, depressive disorders, and anxiety disorders. Metabolic syndrome was diagnosed based on the International Diabetes Federation criteria (IDF, 2005). Data were analyzed and tested for associations between various factors using multivariate logistic regression analysis.</p> <p><strong>Results:</strong> The prevalence of metabolic syndrome was 51.17%. Age, education level, occupation, economic status, current alcohol consumption, use of antidiabetic, antihypertensive, and hypolipidemic agents, duration of psychiatric disease, and antipsychotics were significantly correlated with metabolic syndrome. The duration of psychiatric disease was a risk factor for metabolic syndrome (adjusted odds ratio = 1.055, 95%CI = 1.006 - 1.106), while exposure to agomelatine, bupropion, deanxit, tianeptine, trazodone, and vortioxetine was a protective factor for metabolic syndrome (adjusted odds ratio = 0.405, 95%CI = 0.213 - 0.772).</p> <p><strong>Conclusion:</strong> The prevalence of metabolic syndrome in this group of psychiatric patients was high. These findings support the importance of assessing and monitoring metabolic syndrome in psychiatric patients who are continuously exposured to antipsychotic every year by measuring body mass index, blood pressure, waist circumference, fasting plasma glucose, HDL cholesterol, and triglycerides.</p> 2024-06-20T00:00:00+07:00 Copyright (c) 2024 Journal of the Psychiatric Association of Thailand https://he01.tci-thaijo.org/index.php/JPAT/article/view/268469 Predicting Factors of Six Months Retention in Methadone Maintenance Therapy at Prachuap Khiri Khan Hospital 2024-02-07T09:46:32+07:00 Vinn Jinanarong vinevelus@gmail.com Pavarud Puangsri pavarud.pu@wu.ac.th <p><strong>Objective:</strong> To examine the characteristics of patients who are undergoing long-term methadone treatment at Prachuap Khiri Khan Hospital and to determine which factors predict patient retention in the system for more than six months.</p> <p><strong>Methods:</strong> A descriptive study was conducted on 153 patients.
