ADHD&me: a Randomized Controlled Trial to Target Self-esteem in Youth With ADHD
The goal of this clinical trial is to learn whether the ADHD\&me (ADHD\&ik) intervention can improve self-esteem in youth aged 16-25 years with Attention Deficit Hyperactivity Disorder (ADHD). The ADHD\&me program is a cognitive behavioral therapy (CBT)-based intervention designed to help people with ADHD to develop a more positive view of themselves in their transition to adulthood. The main questions it aims to answer are: * Does the ADHD\&me intervention improve self-esteem in youth with ADHD, and are these effects maintained over time? * Does the intervention also improve related outcomes, such as masking of ADHD-related behaviors and co-occurring mental health symptoms including anxiety, depression, and stress? In this RCT, participants are assigned either to immediate treatment or to a waitlist control condition, with the latter receiving the intervention after an eight-week delay. Participants will: * Take part in seven individual therapy sessions according to the ADHD\&me intervention. * Complete questionnaires about self-esteem, masking of ADHD-related behaviors, ADHD symptoms, and co-ccurring mental health symptoms at several time points. * Complete short daily assessments (ecological momentary assessment) during one week at the start of the study and one week after the intervention or waitlist period to report momentary self-esteem, emotions, distress, and activities.
• 16-25 years old.
• Official ADHD diagnosis, that is confirmed by research team using the clinical interview MINI-S.
• Low self-esteem, determined through a structured and multi-step procedure to minimize subjectivity:
‣ Referral by clinician. Clinicians from participating institutions identify potential participants. To ensure a uniform understanding of the study population and inclusion criteria, all clinicians receive specific training. The researcher(s) conduction the baseline assessment are also familiar with these training materials, so that the inclusion procedure is applied consistently.
⁃ Telephone screening. Two items from the Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1965) are administered (At times I think I am no good at all and All in all, I am inclined to think I am a failure). A score of 3 (agree) or 4 (strongly agree) on either of these items is considered indicative of low self-esteem.
⁃ Baseline confirmation. During the baseline measurement, the full Rosenberg Self-Esteem Scale is administered. A cutoff score of \< 15 is used as an objective reference point. This score is combined with a standardized clinical interview conducted by a trained researcher psychologist. At the ADHD section of the MINI-S at the baseline measurement, participants are asked by the researcher psychologist how their symptoms interfere with domains such as work, study, relationships, and self-esteem. If self-esteem is not mentioned, a follow-up question will be asked: Many people with ADHD feel their symptoms affect their self-esteem, for example due to repeated negative feed- back, feeling like they are not good at things, or failing short. Do you recognize this in yourself? Based on the participant's response, the trained researcher psychologist interviewer forms a professional, clinical impression of whether there are indicators of persistently low self-esteem (i.e.,insecurity, fear of failure, strong reactions to criticism, perfectionism, distress related to ADHD symptoms). This clinical assessment approach is based on examples provided by the Diagnostic Interview for ADHD in Adults (DIVA-2-NL; Kooij \& Francken, 2010). In all doubtful cases, the inclusion decision will be discussed in consensus meetings with the research team and supervisor, ensuring high inter-rater reliability.
• Pharmacological treatment for ADHD is allowed, but medication dose should be stabilized for a minimum of 4 weeks at baseline measurement (T0). Although changes in ADHD medication during the study are not preferred, they may occur in practice. Any such changed will be carefully documented.
