Introduction: Adults with ADHD experience executive function (EF) impairments affecting quality of life (QoL). Combining medication and non-pharmacological treatments is recommended. The Cog-Fun-A intervention, a meta-cognitive, occupation-based approach, shows promise but needs more research.
Objectives: This study aims to assess Cog-Fun-A’s influence on QoL and EF in adults with ADHD and identify predictors of QoL improvement and adherence.
Methods: This retrospective study included 115 adults (39.1% men) aged 19–70, who completed the ADHD QoL measure and BRIEF-A to assess QoL and EF before and after intervention. The Cog-Fun-A program consists of 24 weekly, 1-hour sessions focusing on self-awareness of strengths and ADHD-related executive deficits. It uses education, occupational experience analysis, strategy acquisition, and goal setting to support achieving personal occupational goals.
Results: Among 107 participants, post-treatment scores significantly improved all QoL domains and EFs. Clinically significant QoL changes occurred in 45%, with 34% meeting reliable change criteria. No demographic variables predicted these changes. Female reported gender, frequent pharmacological treatment, and lower baseline BRIEF-A scores predicted intervention completion.
Conclusion: Cog-Fun-A may offer an effective, meta-cognitive occupation-based non-pharmacological treatment for adults with ADHD; however, further research is recommended.
