Abstract

Despite the growing body of work to develop and evaluate treatments for hoarding disorder, little attention has been given to extending these efforts to early intervention. Intervening at an earlier stage when symptoms have not yet met clinical levels may prevent decades of clutter accumulation and the consequences that follow. No research to date has sought to address the full scope of hoarding symptoms in an early intervention. Therefore, the present study piloted and evaluated the feasibility of a cognitive-behavioral, group therapy early intervention for emerging adults with elevated hoarding symptoms. Across an eight-session intervention program, our sample (N = 4) reported substantial decreases in saving cognitions (t[3] = 3.86, p = .031, d = 1.93) and clutter (t[3] = 3.77, p = .033, d = 1.88), with 75% of participants reporting clinically reliable change in overall hoarding symptoms. Implications, limitations, future directions, and considerations for feasibility are discussed.
