Introduction
This case study presents the second phase of our ongoing occupational therapy research, focusing on managing ADHD symptoms and improving life quality. It continues the work initiated in the first phase, extending the study to gather new data and insights.

Case Study of Trial I
Assessing the Effectiveness of Occupational Therapy in Managing ADHD
Learn More
Unlike the structured participant selection in the first phase, where participants were manually recruited and evenly distributed by gender, this phase adopted a more natural recruitment process. Participants independently scheduled their first therapy session through organic website traffic and Google Ads outreach.
While the study reaffirms the effectiveness of occupational therapy, it also highlights key factors that influence therapeutic outcomes. These insights emphasize the importance of encouraging regular participation and understanding the diverse contexts that affect therapeutic outcomes.
Objectives
Participants
Patients: Trial II included 7 participants aged 30–60 years who were selected from a larger group of individuals actively engaged in the trial. These participants met the inclusion criteria, which required agreement to participate in the study and the completion of at least two valid assessment submissions.

Combined with the 7 participants from Trial I, the study comprises a total of 14 individuals, enabling a comprehensive analysis of outcomes across both trials.
Composition
The group consists of individuals aged 30 to over 50, with diverse professional backgrounds spanning multiple industries. Participants demonstrate varying functional levels, reflecting a wide range of life and work contexts.
Challenges
Participants face various challenges, including attention-related difficulties, executive functioning issues, and disruptions in lifestyle and daily routines.
* The categorization of challenges is based on standard classifications used in ADHD research.
Needs
The patients’ described needs can be categorized into developing cognitive and behavioral strategies, improving emotional regulation, managing lifestyle and daily routines effectively, and enhancing social skills and relationships.
* The categorization of needs is based on therapeutic approaches and support strategies commonly used in ADHD treatment.
Methodology
1
Initial Assessment
Comprehensive evaluation of each patient’s symptoms, functional levels, and personal goals. Patients completed the ADHD Quality of Life Assessment and the Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist to quantify their initial state.
* Compared to Trial I, this trial introduced the Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist for a more detailed evaluation of symptoms.
2
Pairing
Matching patients with therapists based on professional background and specific needs.
3
Intervention
4
Monitoring and Evaluation
Pre- and post-intervention assessments using the ADHD Quality of Life Assessment and the Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist to evaluate changes in quality of life and symptom severity. Regular feedback sessions to adjust therapy plans.
5
Sample Selection
Participants are screened based on the submission of at least two qualified assessments, enabling month-on-month comparisons.
* For this study, month-on-month is defined as a comparison between consecutive qualified submissions with an interval of no less than 7 days. Only participants meeting this criterion are included in the final analysis.
Results
The ADHD Quality of Life Assessment Showed Improvement, While the Adult ADHD Self-Report Scale Symptom Checklist Showed a Reduction in Symptoms
Quantitative data from two pre- and post-intervention assessments show an average life quality score increase of 19.6% from the ADHD Quality of Life Assessment and a symptom reduction of 8.8% from the Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist.


Quantitative data was derived from pre- and post-intervention assessments, including Quality of Life measures and the Adult ADHD Self-Report Scale (ASRS v1.1), a 5-point Likert-based tool designed to evaluate ADHD symptoms in adults. These results highlight improvements achieved through personalized therapeutic interventions.
Therapy Frequency Influences Outcomes
Participants in both Trial I and Trial Ⅱ were categorized as consistent weekly patients or intermittent frequency patients, based on the regularity of their therapy sessions.
In Trial I, all participants were classified as consistent weekly patients. In contrast, Trial Ⅱ primarily consisted of intermittent frequency patients, with only a few classified as consistent weekly patients. The improvement observed in Trial Ⅱ was less pronounced compared to Trial I, highlighting the potential impact of consistent engagement on outcomes. This underscores the importance of therapy frequency and sets the stage for further analysis of factors influencing performance across these groups.

More Factors Affecting Performance Enhancement
Beyond therapy frequency, the analysis reveals additional factors that influence performance enhancement across various criteria.
Age shows a clear trend, with older participants experiencing lower improvements in overall performance, life productivity, and psychological health, while life outlook and relationships show minimal variation across age groups.
Therapist impact varies significantly, with some achieving the highest improvements in specific criteria, such as overall performance, life productivity, psychological health, life outlook, and relationships. However, one therapist showed negative outcomes across multiple criteria, though these were exclusively linked to a single patient.
Job group classification also plays a role, with participants in high-functioning roles, such as Physician Assistants, exhibiting greater improvements in most areas compared to those in less likely high-functioning roles, except for relationships, where the difference was negligible.

Quantitative data was derived from pre- and post-intervention Quality of Life assessments using a Likert Scale, highlighting significant improvements through personalized therapeutic interventions.
The sample for Trial I was from June 2024, conducted at a different time than Trial II. Both trials utilized the ADHD Quality of Life Assessment, allowing for the integration of data from both studies to calculate a combined reference improvement value. While the combined analysis provides valuable insights, the differing contexts and timelines of the two trials should be considered when interpreting the results.

Conclusion
The occupational therapy model demonstrated measurable benefits in managing ADHD symptoms and improving functional levels across a diverse patient population. Tailored therapy sessions, supplemented by practical homework assignments, contributed to noticeable improvements in both high-functioning individuals and those facing significant challenges.
However, the findings also highlight the importance of consistent therapy frequency and other factors, such as age, therapist impact, and job roles, in optimizing outcomes. These insights underscore the value of a comprehensive and individualized approach to ADHD management.

Due to the limited number of participants and restrictions related to therapy licensing and regulations, formal occupational therapy services could not be provided in this trial. The coaching intervention was designed to closely replicate the content and approach of occupational therapy, but it was not officially recognized as such. The findings of this case study should be interpreted within this context.
