Background Contamination, when members of a comparison condition receive or are exposed to a treatment under investigation, can bias the direction, statistical significance, and magnitude of treatment effects. Objective This pre-registered study examined whether contamination biased estimates when replicating child maltreatment effects on two established outcomes, externalizing and internalizing behavior problems. Methods A multi-wave, U.S. national probability sample of children and families involved with child protective services ( N = 4000; Age = 0–17.5; Sex = 48% Female; Race = 60% White; Ethnicity = 30% Hispanic). Child maltreatment and comparison conditions were established using official case records and contamination was identified as caregiver-reported maltreatment for those children assigned to the comparison condition. Outcomes were 6-month frequencies of externalizing and internalizing behaviors, represented in T -scores, three years post-maltreatment exposure. Results The prevalence of contamination in this study was 96%. Propensity score analyses that ignored contamination revealed that maltreatment exposure had no impact on externalizing behaviors ( b = 0.28, p = .746) or internalizing behaviors ( b = 0.27, p = .744), failing to replicate prior research. However, propensity score analyses that corrected contamination replicated prior research by generating estimates that were in the expected directions, statistically significant, and moderate to large in effect magnitude for externalizing ( b = 8.72, p = .002, SMD = 0.74) and internalizing behavior problems ( b = 9.96, p < .001, SMD = 0.90). Conclusion Correcting contamination has the potential to improve the replication of child maltreatment effects, strengthening the generalizability of results.
چکیده به فارسی
زمینه: آلودگی، زمانی که اعضای گروه مقایسه، درمان مورد بررسی را دریافت میکنند یا در معرض آن قرار میگیرند، میتواند جهت، معناداری آماری و اندازه اثر درمان را دچار سوگیری کند. هدف: این مطالعه از پیش ثبتشده بررسی کرد که آیا آلودگی برآوردها را هنگام تکرار اثرات بدرفتاری کودک بر دو پیامد تثبیتشده، یعنی مشکلات رفتاری برونیسازی و درونیسازی، دچار سوگیری میکند یا خیر. روشها: نمونهای چندموجی و با احتمال ملی از کودکان و خانوادههای درگیر با خدمات حمایت از کودک در ایالات متحده (N = 4000؛ سن = ۰ تا ۱۷/۵ سال؛ جنسیت = ۴۸٪ دختر؛ نژاد = ۶۰٪ سفید؛ قومیت = ۳۰٪ اسپانیاییتبار) مورد بررسی قرار گرفت. شرایط بدرفتاری کودک و گروه مقایسه با استفاده از سوابق رسمی پروندهها تعیین شد و آلودگی به عنوان گزارش بدرفتاری توسط مراقب برای کودکانی که به گروه مقایسه اختصاص یافته بودند، شناسایی شد. پیامدها، فراوانی ششماهه رفتارهای برونیسازی و درونیسازی، که به صورت نمرات T سه سال پس از مواجهه با بدرفتاری سنجیده شد، بودند. نتایج: شیوع آلودگی در این مطالعه ۹۶٪ بود. تحلیلهای نمره تمایل که آلودگی را نادیده گرفتند، نشان دادند که مواجهه با بدرفتاری تأثیری بر رفتارهای برونیسازی (b = 0.28, p = .746) یا رفتارهای درونیسازی (b = 0.27, p = .744) ندارد و نتوانستند پژوهشهای پیشین را تکرار کنند. با این حال، تحلیلهای نمره تمایل که آلودگی را اصلاح کردند، پژوهشهای پیشین را با ارائه برآوردهایی در جهت مورد انتظار، معنادار از نظر آماری و با اندازه اثر متوسط تا بزرگ برای مشکلات رفتاری برونیسازی (b = 8.72, p = .002, SMD = 0.74) و درونیسازی (b = 9.96, p < .001, SMD = 0.90) تکرار کردند. نتیجهگیری: اصلاح آلودگی میتواند تکرار اثرات بدرفتاری کودک را بهبود بخشد و قابلیت تعمیم نتایج را تقویت کند.

The objective of this community service initiative is to assist parents and teachers in fostering a "Qur’anic generation" that is ASIK, a generation not only proficient in reciting the holy Qur’an but also skilled in language and logical reasoningthereby enhancing the quality of education in Pangkalpinang City. Based on observations and interviews conducted at the Baitul Ma’ruf Quran Education Center (TPA) in Pangkalpinang, several issues have been identified at the TKA/TPA, specifically concerning the quality of services and comfort, education, health, and social aspects. Students also need to develop an awareness of the importance of becoming critical and innovative individuals, so that they do not fall behind as the flow of information continues to accelerate. This community service initiative was carried out in three stages: preparation, implementation, and evaluation. The activities focused on four key aspects: the installation of an organizational structure board and signage for the TKA/TPA to address quality; literacy and numeracy programs (Smart) and religious outreach (Active) to support education; the preparation of traditional Bangka cuisine (Innovative) to promote health; and social outreach sessions (Critical) to foster social engagement among the participants. The activity was attended by 40 students from the Baitul Ma’ruf TKA/TPA (Islamic kindergarten/elementary Quran education center). The participant satisfaction evaluation yielded an average score of 89.28, falling into the "very satisfied" category. The improvement in participants' numeracy literacy skills is evidenced by the results of numeracy literacy assessments: the average score at the beginning of the program was 46.46, which increased to 73.73 following the numeracy literacy learning activities. The outcomes of the activity also included an improved understanding among participants regarding how to deliver a lecture, how to create calligraphy, and how to select natural ingredients native to the Bangka region that can be used to prepare local delicacies with health benefits
Early Childhood Care and Development (ECCD) serve as a foundational framework for the holistic growth and lifelong learning of young children. In the Philippines, its implementation is mandated by Republic Act No. 10410 and strengthened by Republic Act No. 12199, which emphasize quality early childhood education delivered by competent Child Development Workers (CDWs) and supported by strong institutional systems; however, implementation continues to face challenges related to limited resources, professional development gaps, administrative constraints, and varying levels of community and parental involvement. This study examined the level of readiness and the challenges encountered by CDWs in implementing the ECCD Curriculum in Barangay Child Development Centers in the Municipality of Mabinay, Negros Oriental. A quantitative descriptive-correlational design was employed, using a validated researcher-made Likert-scale questionnaire administered to ten (10) purposively selected CDWs during School Year 2025–2026. Data were analyzed using frequency, percentage, weighted mean, and Pearson product-moment correlation at the 0.05 level of significance. Findings revealed that the respondents were highly ready in their understanding of the ECCD curriculum (WM = 4.28) and in pedagogical skills and instructional practices (WM = 4.28), but only moderately ready in terms of resources and materials (WM = 3.80) and support, supervision, and professional development (WM = 3.84). Challenges were generally moderate, with insufficient toys and learning materials, varied learning needs of children, and heavy workload and administrative tasks emerging as the most notable concerns. ECCD-related training showed a strong, significant positive relationship with readiness (r = 0.795, p = 0.006), whereas age, educational attainment, and years of experience were not significantly related to readiness, no profile variable was significantly related to the challenges encountered, and readiness was not significantly related to challenges (r = 0.081, p = 0.824). The study concludes that while CDWs are generally prepared to implement the ECCD Curriculum, their effectiveness is constrained by largely systemic and environmental challenges. These findings imply the need for continuous professional development combined with improved resource allocation, reduced administrative workload, strengthened institutional support, and stronger collaboration among local government units, parents, and community stakeholders.
Generation Alpha (born 2010-2024) and Generation Beta (born 2025-2039) represent an unprecedented developmental archetype defined by total digital integration and ubiquitous artificial intelligence (AI). This empirical study evaluated specialized psychological adaptation mechanisms, parenting models, and mental health intervention frameworks across these cohorts. Utilizing a mixed-methods design, quantitative data were gathered from $N = 300$ parents (Gen Alpha parents and expectant/early Gen Beta parents) using the Modified Parental Stress Scale (PSS) and Child Behavior Checklist (CBCL), supplemented by qualitative interviews with $N = 20$ pediatric mental health experts. Independent samples $t$-tests confirmed that Gen Alpha/Beta display significantly higher digital dependency anxiety ($M = 38.60, p < .001$) alongside superior visual-spatial intelligence ($M = 44.10, p < .001$) relative to normative baselines. Crucially, a proactive "Digital Integration" co-navigation parenting framework yielded significantly lower parental stress ($M = 29.50$) compared to rigid "Digital Detox" restriction models ($M = 42.80, p < .001$). A preventive clinical framework focusing on Social-Emotional Learning (SEL) and cognitive impulse management is proposed.
Children's behaviour and social adjustment within the classroom are important considerations. Behaviour can refer to how a pupil engages with learning tasks, follows instructions, works with others and interacts within the classroom. Social adjustment can relate to how children feel they fit in, build friendships, communicate effectively and feel included. Although behaviour and social adjustment are two distinct areas, they will be influenced by each other. This conceptual article will discuss the relationship between behaviour and social adjustment for upper primary school students. Using theories such as ecological systems, social learning and sociocultural. School engagement, friendships and school belonging will also be discussed. It is important to consider how behaviour should be seen as more than just an individual trait. Family factors, teaching style, peer relationships, individual differences and school factors can influence how a pupil behaves. A strength based approach to children's behaviour and social adjustment will be advocated. The article will conclude with key implications for classroom settings and recommendations for future research. Future research should be culturally aware, developmentally appropriate and ethical. This article is theoretical and will not give any findings.
Toilet training is an essential developmental process that fosters discipline and independence in early childhood. The acquisition of toileting skills is significantly influenced by parenting approaches. Authoritative (democratic) parenting, characterized by warmth, two-way communication, and clear boundaries, offers supportive guidance during this developmental transition. This study aimed to investigate the effect of an authoritative parenting style on toilet training ability among children aged 3–4 years. A quantitative research design with a correlational approach was employed, involving 206 parents of children aged 3–4 years selected via questionnaire distribution. Data were collected using the adapted Parenting Styles and Dimensions Questionnaire-Short Version (PSDQ-SV) and the Toilet Training Readiness Scale (TTRS), and analyzed using binary logistic regression. The results revealed a statistically significant association between authoritative parenting and toilet training outcome (p = .018, p .05), though accounting for a modest proportion of the overall variance. These findings suggest that while authoritative parenting contributes positively to early toilet training progression, consistent parental guidance and child-centered readiness factors remain vital.
