The role of parental health literacy in paediatric ADHD treatment: An observational study from Türkiye
Objectives: Parental health literacy is an important issue in paediatric chronic disease, but its role in attention deficit hyperactivity disorder (ADHD) treatment remains underexplored. This study aimed to investigate health literacy levels among parents of children diagnosed with ADHD and to evaluate the relationships between these levels, parents' decisions to accept or refuse pharmacotherapy for their children's ADHD treatment, and their children's ADHD symptoms. Design: A total of 133 children with ADHD and their parents (mothers and fathers) participated in this single‐centre observational study. Participants were divided into two groups: Group 1 ( n = 68): parents who accepted pharmacotherapy and their children who started treatment; Group 2 ( n = 65): parents who refused pharmacotherapy and their children who did not start treatment. Methods: Parental health literacy was assessed using the European Health Literacy Survey Questionnaire (HLS‐EU‐Q), and ADHD children's clinical characteristics were evaluated using the Conners' Parent Rating Scale‐Revised/Long (CPRS‐R/L) and the Clinical Global Impression (CGI) Scale. Results: Both groups had similar sociodemographic characteristics and maternal and paternal health literacy levels. In Group 1, positive correlations were found between maternal and paternal health literacy indices, as well as between CGI‐I and many subscales of the CPRS‐R/L (change scores = post‐treatment–pre‐treatment). Additionally, in Group 1, relationships were identified between maternal and paternal health literacy indices and many subscales of the CPRS‐R/L (pre‐treatment/post‐treatment/change scores), but no relationships were found between these indices and CGI‐I scores. Conclusions: These findings may suggest that assessing parental health literacy and promoting interventions to improve it could be helpful in the management of paediatric ADHD treatment.

Sustainability Literate Preschool Teachers: Exploring Knowledge, Attitudes and Practices in Early Childhood Education for Sustainability—A Quantitative Model
This study aimed to explore preschool teachers' knowledge, attitudes and practices regarding early childhood education for sustainability within the framework of sustainability literacy. To achieve this, we validated the Sustainability Literacy Survey, combining three sections: the Sustainable Development Knowledge Scale, the Attitude toward Sustainable Development Scale and the Early Childhood Education for Sustainability Practices Scale. The survey assesses teachers' understanding of sustainability concepts, their willingness to incorporate sustainability into their teaching, and how they implement sustainability‐related practices in their classrooms. We collected data from 345 teachers serving at public and private preschools in Türkiye. Participants varied in teaching experiences and educational backgrounds. Analyses began with exploratory and confirmatory factor analyses to establish the validity and reliability of the three scales. Then, we conducted correlation and regression analyses to examine the relationships among knowledge, attitudes and practices, while t‐tests identified differences based on external factors such as school type. The results indicated that education for sustainability practices is primarily driven by teachers' knowledge and attitudes rather than their education level. Although in‐service and preservice programs correlated sustainability‐related understanding, this knowledge did not directly predict classroom practices. Instead, positive attitudes emerged as the critical factor linking knowledge to sustainability practices.

A Collaboration Project on Education for Sustainability: A Qualitative Evaluation of Professional Development Program for Turkish Preschool Teachers
This article is dedicated to examining a bilateral project established between the Republic of Korea and Türkiye, with the overarching objective of elevating awareness and endowing preschool teachers with the capacity to embed education for sustainability (EfS) within their classroom practices seamlessly. For this purpose, a professional development (PD) program was developed regarding three pillars of sustainability and 7R themes. Fourteen preschool teachers attended the PD program. Three teachers participated in this case study to reveal teachers' transformation regarding sustainability and early childhood education for sustainability. The data were collected through pre-post-follow-up interviews and classroom observations. Thematic content analyses were conducted. According to the results, the PD program enhanced and deepened teachers’ sustainability knowledge. In addition, teachers could transfer the knowledge from the PD program on education for sustainability into their practice not entirely but acceptably, and they have a chance to reconsider their lifestyle habits regarding sustainability in many areas.

Abuse and Neglect of Children With Specific Learning Disorders in Türkiye: A Case–Control Study
Background: Although it is often stated that children with special needs are at risk of being abused and neglected, research conducted on the abuse of children with specific learning disorders (SLDs) is limited.Methods: This case–control study aims to compare exposure to neglect and abuse among children diagnosed with SLDs (case group) and children with typical development (control group). The study included children aged 6 to 12 years who were referred to the Child and Adolescent Psychiatry Outpatient Clinic and Pediatric Clinic of a hospital in Türkiye. The data collection process included 196 participants and lasted for 7 months in 2020.Results: Based on the analysis of the data collected with the Schedule for Affective Disorders and Schizophrenia for School Age Children‐Present and Lifetime Turkish Version (K‐SADS‐PL‐T) and the Abuse Assessment Questionnaire, we determined that children with SLDs were physically and emotionally abused more than the children of the control group. In addition, they witnessed violence between their parents more than the control group. Physical abuse, emotional abuse and witnessing family violence were identified as significant predictors for SLD.Conclusions: The presence of SLDs is a significant risk factor for children to be exposed to abuse even in the absence of ADHD as a comorbidity.

AÇIK HAVA OYUN PARKLARINDA RİSKLİ OYUNA ÇOK YÖNLÜ BAKIŞ
Çocukların oyunlarında risk almaları ve oyun alanlarında riskli ekipmanların bulunmasının gelişimsel faydaları giderek daha fazla araştırmaya konu olmaktadır. Özellikle şehirleşmeyle birlikte çocukların oyun tercihleri de değişiklik göstermektedir. Bu araştırma Türkiye'de bulunan bir büyükşehir belediyesine ait açık hava oyun parklarının riskli oyun olanaklarının gözlemler ve görüşmelerle derinlemesine incelenmesini amaçlamaktadır. Araştırma kapsamında açık hava oyun parklarının fiziksel özellikleri ve çocukların bu parklardaki oyun davranışları gözlemlenmiş; ayrıca yerel yönetimlerden bir yetkili ve ailelerle yapılan görüşmelerle riskli oyunların potansiyel ve uygulamadaki destekleyicileri derinlemesine ortaya koyulmuştur. Araştırma sonunda, oyun park alanlarında yüksek hız ve büyük yükseklik kategorilerindeki unsurların sıklıkla gözlemlendiği fakat riskli oyunlarda kullanılabilecek tehlikeli unsur ve aletlerin neredeyse hiç gözlemlenemediği ortaya çıkmıştır. Oyun park alanlarında gözlemlenen ekipmanlara paralel olarak çocukların riskli oyunlarında da en sık yüksek hızda koşma ve yüksekliklerde sallanma/atlama gibi davranışların ortaya çıktığı bulunmuştur. Aileler ve yerel yetkili ile yapılan görüşmeler sonucunda; ekipmanlara karar verme süreçlerinin ve ailelerin riskli oyunlara yönelik görüşlerinin çocukların riskli oyunlarında rolü olduğunu söylemek mümkündür.

Investigation of bilingual first-grade students’ school readiness
This study was designed as a case study and the school readiness of first-grade bilingual students speaking Turkish and Kurdish was examined according to gender, whether they had preschool education, the language spoken at home, the number of siblings, and the educational background of their parents. The study group consisted of 300 children who started first grade in primary school in Viranşehir district of Şanlıurfa province, Turkey, in the 2014-2015 academic years and 15 first grade teachers working in this province. The data were collected using the Metropolitan Readiness Test, semi-structured Teacher Interview Form, and Family Information Form. The obtained data were evaluated with a two-way analysis of variance and content analysis. The results of this study revealed that receiving preschool education, the language spoken at home, the number of siblings, and the educational background of parents made a significant difference in the school readiness of the children, but the gender did not make a significant difference. As a result of the interviews with the primary school first-grade teachers, it was determined that children who received preschool education started primary school more ready than those who did not and that the family played an important role in school readiness.

Metaphors in anti-bias educational program: Educators’ voices
The purpose of this research is to review the perceptions of faculty members, preschool teachers, and pre-school teacher candidates with regard to the Anti-Bias Education Programs (ABEP) by using a phenomenological pattern. The participants’ metaphors on ABEP were established and categorized and the differences in participants’ perceptions were analyzed in terms of their demographic characteristics such as age, gender, and service time. The working group of this research consisted of 129 participants: from 17 universities, 22 faculty members from the Education Faculty Pre-school Education Departments and 71 pre-school teacher candidates, studying in the fourth year of the Pre-School Education Departments; and 36 pre-school teachers from 9 different cities. The findings of this study show that faculty members produced 17, teachers produced 28 and teacher candidates produced 30 different metaphors about ABEP. The faculty members’ metaphors vary in terms of age and service time, whereas the teachers’ vary in terms of service time, type of institution, education level and age. Teacher candidates’ metaphors vary in terms of age and gender.
