Non-immersive virtual environments for the treatment of hoarding disorder: a preliminary randomized controlled trial based on a non-clinical sample.
Trial report in BMC psychology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
purposeHoarding Disorder (HD) is characterized by persistent difficulty discarding possessions, leading to excessive accumulation and functional impairment. Traditional treatments, based on cognitive-behavioral therapy (CBT), emphasize motivational enhancement, cognitive restructuring, and exposure-based interventions. However, these methods face challenges, including heightened distress during in vivo exposure and avoidance tendencies. Virtual Reality (VR) has emerged as a promising adjunctive tool, offering immersive, controlled environments for gradual exposure. The current preliminary study investigates the efficacy of non-immersive VR, defined as a computer-generated environment accessed via a standard screen without head mounted displays or motion tracking, in facilitating the discarding of personal belongings compared to imaginative exposure.
methodEighty participants from non-clinical convenience sample (mean age = 25.98, SD = 9.84) were randomly assigned to Virtual Reality Exposure (VRe) or Imagination Exposure (Ie). A non-immersive VR environment was created using Blender and GODOT software, simulating a non-immersive virtual home where participants interacted with representations of their objects. Psychological constructs, including state anxiety and positive and negative feelings, were measured using validated self-report tools (STAI-Y1, PANAS). Behavioral outcomes focused on object discarding frequency during exposure and in vivo sessions.
resultsResults demonstrated a significantly higher proportion of successful discarding in the VR group compared to the imagination group during the experimental exposure session (87.5% vs. 50%; p < .001).
conclusionVR’s realistic sensory-motor engagement may help circumvent cognitive and emotional barriers to exposure tasks, increasing the ecological validity of these techniques. This preliminary study indicates that non-immersive VR may play a role in bridging the gap between imaginative-based exposure therapy and in vivo HD, that is, real-life exposure to discarding personal items. Although replication in clinical populations and long-term outcome data will be needed, non-immersive VR may provide a cheap, broadly available tool to improve treatment engagement and efficacy. Therefore, future research should analyze the relative advantages of immersive-type VR systems and improve assessment instruments to capture subtle changes over time in psychological constructs. This study was conducted according to the Declaration of Helsinki and was approved by the Ethics Committee of Psychological Research (Area 17), University of Padova (approval number: DD0A28FFB2B4C63CFED6CC9BACC7A530).
