Professionals in Big Four audit firms work under high-pressure conditions—heavy workloads, strict deadlines, and limited autonomy—which can gradually erode intrinsic motivation and day-to-day psychological functioning. This study evaluated the effectiveness of the Integrated Flow Model Intervention, a strength-based program grounded in work-related flow, self-determination, and meaningful work. A quasi-experimental two-way mixed-design MANOVA (Time × Group) was conducted across three measurement points (pre-test, post-test, follow-up). Twenty-one professionals from KPMG Thailand participated in a two-session workshop in small groups of 5–6 participants, followed by a one-month practice period. The program emphasized strength–challenge alignment, clear proximal goals, immediate feedback, meaningful-work reflection, and digital-attention regulation. Data were collected using validated instruments with acceptable to excellent reliability (Cronbach’s α = .79–.96 across scales). Results indicated significant multivariate effects of Time on flow-related indicators and Positive Affect (Pillai’s Trace = .674, p < .001), and a significant Time × Group interaction (Pillai’s Trace = .504, p = .018), showing that participants in the experimental group experienced improvements in Absorption, Work Enjoyment, Intrinsic Motivation, and Positive Affect. Task Achievement remained relatively stable across groups, indicating that while psychological functioning improved, self-perceived performance levels were maintained. These findings highlight the Integrated Flow Model Intervention as a practical, evidence-based approach that organizations can adopt to strengthen employees’ psychological functioning, intrinsic motivation, and work-related flow experiences, offering a low-cost and scalable solution for enhancing work experiences in high-pressure environments.
