OBJECTIVE: To retrospectively evaluate the comparative effect of two wheelchair seating systems, Custom-Contoured Wheelchair Seating (CCS) and Modular Wheelchair Seating (MWS), on scoliosis progression in children with neuromuscular and neurological disorders and to determine any predictors for scoliosis progression.
METHODS: Longitudinal, retrospective cohort study SETTING: National Health Service regional posture and mobility service PARTICIPANTS: Non-ambulant paediatric wheelchair users with neuromuscular and neurological disorders (N = 75; 36 male, 39 female; mean age at seating intervention, 10.50 ± 3.97 years) issued CCS and MWS by the South Wales Posture and Mobility Service from 2012 to 2022.
METHODS: Two specialized wheelchair seating systems, CCS and MWS.
METHODS: A generalized least squares (GLS) model was used to estimate the effect of seat type on Cobb angle over time.
RESULTS: Of the 75 participants enrolled, 51% had cerebral palsy. Fifty were issued CCS and 25 were issued MWS. Baseline Cobb angle was 32.9±18.9° for the MWS group and 48.0±31.0° for the CCS group. The GLS model demonstrated that time since seating intervention (χ2 = 122, p < .0001), seating type (χ2 = 52.5, p < .0001), and baseline scoliosis severity (χ2 = 41.6, p < .0001) were predictive of scoliosis progression. Condition was not a strong predictor (χ2 = 9.96, p = .0069), and sex (χ2 = 5.67, p = .13) and age at intervention (χ2 = 4.47, p = .35) were not predictive. Estimated contrasts of medical condition with seat type over time demonstrated smaller differences between MWS and CCS over time. Predicted scoliosis velocity was found to attenuate with use of CCS over time compared to MWS, although, scoliosis deteriorated regardless of intervention.
CONCLUSIONS: Our findings showed paediatric wheelchair users with neurological and neuromuscular disorders prescribed CCS showed greater mitigation of scoliosis progression over time compared to those issued MWS.

BACKGROUND: Previous research identifies organisational culture as one of a number of factors associated with the quality of life outcomes of group home residents\' with intellectual and developmental disabilities. This study aims to elaborate on the dimensions of group home culture in settings in England.
METHODS: Participant observations and semi-structured interviews with staff were carried out in two group homes. Field-notes, interview notes and transcripts were analysed using inductive thematic analysis by a researcher naïve to the project and the previous literature. Initial coding was re-examined after sensitisation to theorised models in previous literature to identify the most parsimonious fit. The two settings were rated and compared using a five-point Likert scale for each of the dimensions.
RESULTS: The findings describe group home culture across seven dimensions. There were mixed ratings across the different dimensions reflecting inconsistencies in culture that were reflected in staff practice. The challenge in assigning a global rating of culture in group homes, which includes interactions across multiple staff and multiple residents over time, was highlighted.
CONCLUSIONS: The development of an observational measure of culture is highlighted as potentially helpful in understanding and responding to culture in services for individuals with intellectual and developmental disabilities.

BACKGROUND: The main cause of growth and development delays remains unknown, but it can occur as an interaction between genetic, environmental, and socio-economic factors.
OBJECTIVE: The aim of the study was to investigate the prevalence and social determinants of growth and developmental delays among children aged under five years in Qazvin, Iran.
METHODS: A cross-sectional study was conducted between January 2019 to December 2020 with participation of 1800 mothers with children aged 4-60 months who were referred to comprehensive health centers in Qazvin city, Iran. Structural and intermediate social determinants of health were assessed including: parents and children socio-demographic characteristics, families\' living and economic status, parents\' behavioral factors, household food security, mother\'s general health, and perceived social support. Children\'s growth was assessed based on their anthropometric assessment and their development was assessed using their age-specific Ages and Stages Questionnaire. Data were analyzed using univariable and multivariable logistic regression models using SPSS software version 24 and Stata version 14.
RESULTS: The prevalence of developmental problems in each domain were 4.28% for personal and social delay, 5.72% for gross motor delay, 6.5% for communication delay, 6.72% for fine motor delay, and 8% for problem-solving delay. The prevalence of weight growth delays was 13.56% and height growth delays was 4.66%. Communication, gross motor, and problem-solving delays were higher among children whose fathers\' smoked cigarettes. Fine motor delays were lower among mothers with education status of high school diploma and university degree vs. the under diploma group. Personal and social delay was significantly higher among families with fair economic status and lower among children when their fathers were employed (vs. unemployed). Weight and height growth delays were higher among mothers who had experienced pregnancy complications and household food insecure families, respectively.
CONCLUSIONS: There are different predictors of growth and developmental delay problems among Iranian children aged under five years including fathers\' smoking, families\' economic status, and household food insecurity as well as history of mothers\' pregnancy complications. The present study\'s findings can be used to screen for at-risk of growth and developmental delays among children and could help in designing and implementation of timely interventions.

BACKGROUND: Early identification of suspected developmental delays (SDDs) is crucial for planning early interventions. This study aimed to determine the prevalence of SDDs and the associated determinants in children aged 12 months in the northeast of Iran, using the Age and Stage Questionnaire-3 (ASQ-3) as the evaluative tool.
METHODS: This study conducted an analytical cross-sectional design to investigate all children who had completed the ASQ-3 screening form at 12 months of age within the time frame of 2016-2023 in the northeast of Iran. The necessary data were extracted from the electronic health record database associated with Mashhad University of Medical Sciences. To examine the factors associated with SDDs within each domain of the ASQ-3, a multiple logistic regression model was employed, and the results were presented using ORs along with 95% CIs.
RESULTS: Over 7 years, 236 476 children (96.74%) underwent routine ASQ-3 screening at 12 months. After excluding certain cases, 226 076 children (95.60%) were included. Among them, 51 593 children (22.82%) had a score below -1 SD, indicating SDD prevalence in at least one domain. The social-personal domain had the highest prevalence with 22 980 children (10.16%), while the gross motor domain had the lowest with 5650 children (2.50%). Logistic regression analysis identified strong predictors of SDDs, including hospitalisation at birth (OR=1.85, 95% CI:1.69 to 2.02), prematurity (OR=1.56, 95% CI: 1.37 to 1.79), urbanisation (OR=1.51, 95% CI: 1.45 to 1.57), boys (OR=1.36, 95% CI: 1.31 to 1.40) and lack of exclusive breast feeding until 6 months (OR=1.30, 95% CI: 1.25 to 1.34).
CONCLUSIONS: The prevalence of SDDs highlights the urgency for prompt action, while considering contributing factors. Policymakers can address modifiable risk factors associated with SDDs, including urbanisation risks, support programmes for immigrant families and the importance of exclusive breast feeding until 6 months. Additionally, it is recommended establishing gender-specific local standard cut-off points for the ASQ.

OBJECTIVE: To analyze needs and requirements of Pediatric Physical Therapists (PPTs), parents, children and adolescents with and without developmental disabilities in the future use of an activity monitor prototype (AM-p) in everyday clinical practice.
METHODS: Qualitative exploratory study with a thematic analysis approach, based on Braun and Clarke\'s six steps. Codes derived from the analysis and central themes were collated, based on Fleuren et al.\'s groupings of determinants.
RESULTS: We interviewed 25 PPTs, 12 parents, and 12 children and adolescents. Within four groupings of determinants, we found nine themes: 1) development of information materials; 2) application: output visualization and ease of use; 3) design; 4) relevance and acceptance; 5) shared decision-making; 6) compatibility in daily living; 7) finances, 8) time, and 9) legislation and regulations.
CONCLUSIONS: End-users have similar basic needs, with individual fine-tuning to be addressed during further development of the AM-p. A child-friendly design, information material, and an easy-to-use application to read and interpret results, need to be developed. Efficient training for PPTs is important for the use of the AM-p and analysis of results. Communication between PPTs and children as well as parents enhances shared decision-making. We recommend involving diverse end-users to enable maximum customization of the AM-p.

Extinction bursts, or temporary increases in rates and intensities of behavior during extinction, can preclude the inclusion of extinction in intervention packages meant to suppress severe challenging behavior. To identify underlying behavioral mechanisms responsible for response persistence and bursting, 69 adults with developmental disabilities completed a low-stakes translational investigation employing a 2 × 2 factorial, crossed, and randomized matched blocks design, with batched randomization logic. In each of the four test groups, we made distinct antecedent manipulations with two value parameters commonly studied through behavioral economics (i.e., demand intensity, Pmax) and evaluated the extent to which each of these manipulations influenced target responding during extinction. Although we found statistically significant differences attributable to both parameters, variations in reinforcer consumption relative to demand intensity were most influential across all dependent variables. This outcome implicates consumption relative to demand intensity as both a mitigating and exacerbating preextinction factor that influences the prevalence of adverse collateral extinction effects (e.g., bursts).

This study addresses the paucity of research on parents of extremely preterm adolescents (born <27 weeks of gestation) and their experiences within the framework of parental determinism. We conducted semi-structured interviews with twenty-two mothers and one father. Data were analysed thematically, revealing three overarching themes and eight subthemes shaping parental accounts. These themes centred on parental ambitions for their children, their perceptions of their child\'s abilities, and the parenting behaviours employed to support parental aspirations. Parents\' actions were influenced by their ambitions and the belief that they could impact their child\'s future independence. While some parents adopted \'trusting\', non-intensive parenting behaviours, those anticipating challenges for their child\'s future independence resorted to intensive parenting practices. These findings align with the concept of parental determinism, emphasising the perceived causal link between present parental actions and future child outcomes. In the context of extreme prematurity, a nuanced understanding of parental perceptions regarding their child\'s future independence aligned with a delicate balance between hope and realistic aspiration is crucial for enhancing parental support and well-being.

BACKGROUND: Responsive teaching (RT) interventions, which enhance developmental outcomes by improving children\'s engagement behaviors, are traditionally delivered in person. However, the coronavirus disease 2019 pandemic complicated this approach.
OBJECTIVE: This study aimed to evaluate the efficacy and acceptance of online RT in children with developmental disabilities and their parents.
METHODS: This pilot study was conducted in Jinju, South Korea, and enrolled parent-child dyads referred to Gyeongsang National University Hospital for developmental concerns between April and September 2022. The children underwent a comprehensive developmental evaluation. The parents received a 5-session RT intervention via ZOOM on a mostly weekly basis. The first 2 sessions involved child development and RT lectures, while the others involved coaching on 3 of the 66 RT strategies. Problem behaviors, parent-child interactions, and parenting stress were assessed pre- versus postintervention using the Korean versions of the Child Behavior Checklist, Maternal/Child Behavior Rating Scale, and Parent Stress Index 4th Edition Short Form, respectively. Acceptability was evaluated using a self-administered questionnaire.
RESULTS: Of the 30 recruited parent-child pairs, 23 (76%) completed the intervention and assessments. The children (mean age, 2.66±0.86 years) included 12 with language delays, 7 with autism spectrum disorder, and 4 with global delays. Predominantly mothers (96%) participated. Online RT significantly improved pivotal behaviors- including joint attention (P=0.04), cooperation (P=0.01), and affect (P=0.01)-and reduced overall problem behaviors (P=0.04). Parents reported less parenting stress (P=0.01), improved interactive behaviors with increased responsiveness (P<0.01), and decreased directiveness (P<0.01). High satisfaction with online RT interventions was also previously reported.
CONCLUSIONS: These findings suggest that online RT can improve children\'s emotional and behavioral outcomes and maternal interaction styles and reduce parenting stress, offering accessible interventions amid challenges such as limited access and pandemics.

BACKGROUND: Developmental delays are common among children with sickle cell disease (SCD). Existing guidelines support consistent screening to increase the identification of deficits and support referral to rehabilitative interventions, yet adherence remains variable. This study sought to assess current practices and identify barriers and facilitators to improve developmental screening for children 0-3 years with SCD.
METHODS: A mixed methods approach, guided by the Exploration and Preparation stages of the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework, assessed developmental screening practices among primary care providers and hematologists. Phase 1 included the SCD Developmental Surveillance and Screening Guideline and Practice Survey. Phase 2 included the SCD Developmental Screening Organizational Survey alongside semi-structured interviews. Descriptive and qualitative methods summarized the findings.
RESULTS: Thirty-three providers from general pediatrics and hematology completed phase 1. Use of standardized developmental screening measures was variable, with the most frequently used being the Modified Checklist for Autism in Toddlers (77%) and the Ages and Stages Questionnaire (55%). Fifteen providers participated in phase 2, and reported they were most likely to engage in changes to improve their practice (mean = 4.4/5) and least likely to support spiritual health and well-being (mean = 3.5/5). Three themes emerged:(i) developmental screening is not standardized or specific to SCD, (ii) children with SCD benefit from a multidisciplinary team, and (iii) healthcare system limitations are a barrier.
CONCLUSIONS: Developmental screening is inconsistent and insufficient for young children with SCD. Providers are interested in supporting children with SCD, but report a lack of standardized measures and consistent guidance as barriers.

BACKGROUND: The impact of parent-childbearing age on child development at 36 months of age is controversial.
OBJECTIVE: We used data from a large cohort study with multiple imputation and mediation analyses of variables.
METHODS: A total of 72,606 parent-child pairs from the Japan Environment and Children\'s Study were included in the study. Parents\' ages were categorized into five groups. We used five domains of the Japanese translation of the Ages and Stages Questionnaire, Third Edition (J-ASQ-3). Scores below the cutoff value at 36 months were defined as developmental delays in each domain. We used three logistic analysis models. In Model 3, we analyzed maternal and paternal age using other variables and covariates.
RESULTS: The outcome was a developmental delay in the five domains of J-ASQ-3. In Model 3, ORs for the developmental delay scores regarding parental age were significantly associated with all five domains of J-ASQ-3. The mediation analysis showed a significant mediation interaction effect for mothers but localized for fathers.
CONCLUSIONS: Advanced paternal and maternal ages were associated with developmental delay in children. Awareness of the risks of childbearing at an advanced age is crucial.
UNASSIGNED: This manuscript used data from a large cohort study with multiple imputation and mediation analyses. With these analyses, we identified the pure effect of advanced parental age on their children\'s development at 36 months.
