This study investigates the impact of temporal adaptation interventions on children with Attention Deficit Hyperactivity Disorder (ADHD), focusing on activity self-efficacy, time perception, daily activity routines, and executive functions. The intervention aims to address the challenges ADHD children face in time processing abilities, which include understanding the concept of time, being punctual, initiating and completing daily activities independently, planning and completing long-term projects, using a calendar, and hurrying when necessary.

The research will be conducted at the Hacettepe University Faculty of Health Sciences Department of Occupational Therapy's educational and research units. Participants will be children diagnosed with ADHD by a Child and Adolescent Psychiatrist. These children will then be randomly assigned to control and training groups. A total of 60 individuals, 30 for each group, will be included in the study based on power analysis. The effectiveness of the study will be shared, and should it prove effective, the same study will be replicated with the control group.

The intervention consists of activities designed to enhance temporal adaptation, adapted for ADHD from models in the literature. Over 10 weeks, the children will engage in weekly 60-minute sessions, each week focusing on different activities to improve temporal adaptation skills. Activities include teaching concepts of calendars and clocks, rhythm exercises with metronomes, time estimation games, daily and weekly planner preparation, time matching games, and exercises to improve time management and planning abilities.

Data will be collected using various tools including a demographic information form, time perception threshold measurement tasks, temporal production tasks, Child Activity Self-Assessment Scale (COSA), and Executive Functions and Occupational Routines Scale (EFORTS). The study's hypotheses test the null hypothesis that temporal adaptation intervention does not affect activity self-efficacy, time perception, daily activity routine, and executive functions in children aged 9-12 with ADHD.

This comprehensive approach aims to enhance the daily lives of children with ADHD by improving their ability to manage time effectively, thereby positively affecting their education, self-care, social relationships, and overall quality of life.

This study explores the efficacy of a temporal adaptation intervention in enhancing the quality of life and functional abilities of children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). ADHD is a neurodevelopmental disorder characterized by patterns of inattention, impulsivity, and hyperactivity that detrimentally influence an individual's academic, social, motor, sensory, and executive functioning. Notably, children with ADHD often struggle with time processing abilities, which can manifest as difficulties in understanding time concepts, adhering to schedules, and managing daily activities.

Background ADHD significantly impacts the cognitive and behavioural domains of affected children, leading to challenges in daily living and academic achievement. Previous research has identified specific issues in time perception and temporal processing among children with ADHD, including time duration discrimination and time reproduction. These difficulties extend to both the understanding and management of time, impacting their daily routines and task completion. Functional and structural imaging studies have shown that the brain regions involved in time processing overlap with areas implicated in the pathogenesis of ADHD, such as the neocerebellum, basal ganglia, and prefrontal cortex. Given the centrality of time management skills to academic performance, self-care, and social interactions, interventions aimed at improving these skills could significantly enhance the functional outcomes for children with ADHD.

Objective The primary objective of this research is to evaluate the effectiveness of a temporal adaptation intervention aimed at improving activity self-efficacy, time perception, daily activity routines, and executive functions among children with ADHD. The intervention seeks to address the specific temporal processing challenges faced by these children, potentially leading to better time management, planning, and organizational skills.

Methods The intervention will be structured around a series of activities and individual sessions designed based on models of temporal adaptation training adapted for ADHD. These activities will target the development of skills related to the understanding and management of time, such as using calendars and clocks, estimating the duration of activities, and planning and executing daily and long-term tasks.

Setting and Participants The research will be carried out at a university's health sciences faculty, utilizing its educational and research facilities. The study will include children who meet the inclusion criteria of being diagnosed with ADHD, within the age range of 9-12 years, and voluntarily agree to participate. Exclusion criteria include the presence of additional diagnoses and the unwillingness of parents to adhere to the intervention protocols.

Design A randomized controlled trial design will be employed, with participants being randomly assigned to either the intervention or control group. The intervention group will undergo the temporal adaptation training program, while the control group will receive no such training. The training program will span 10 weeks, with sessions held once a week for 60 minutes. Each session will focus on different activities tailored to improve temporal adaptation, such as teaching time concepts, rhythm exercises with a metronome, and games designed to enhance time estimation and planning skills.

Assessment Tools

A comprehensive set of tools will be used to evaluate the impact of the intervention on the participants, including:

Demographic Information Form: To collect baseline demographic data. Time Perception Threshold Measurement: To assess the ability to discriminate between different durations.

Temporal Production Task: To evaluate the accuracy of reproducing time intervals.

Child Activity Self-Assessment Scale (COSA): To measure perceived efficacy and importance in daily activities.

Executive Functions and Occupational Routines Scale (EFORTS): To assess executive functioning and daily routines.

Hypotheses The study will test several hypotheses, including the assumption that the temporal adaptation intervention has no effect on the measured outcomes. The alternative hypothesis posits that the intervention will significantly improve activity self-efficacy, time perception, daily activity routines, and executive functions in participating children.

Data Analysis Statistical analyses will be conducted using appropriate software, with comparisons made between pre- and post-intervention assessments within and between the intervention and control groups. The effectiveness of the intervention will be determined through Cohen's Effect Size, with predefined criteria for interpreting the magnitude of the effect.

Conclusion This study aims to provide evidence on the effectiveness of a temporal adaptation intervention for children with ADHD, focusing on enhancing their ability to understand and manage time. By improving time management and planning skills, the intervention seeks to positively affect educational achievements, self-care, social relationships, and overall quality of life for these children.

Inclusion Criteria:

The data that are collected in this study contain individuals' performance scores on various tests, which can be indirectly related to their academic success and overall academic performance. Therefore, the informed consent that is collected from the participants states that their data will not be shared with third parties (any person or institution except for the research team and related ethical boards) except for ethical committees. Therefore, the data will not be shared with other researchers.
