Two weeks to tune in: Evaluating the effects of a short‐term body scan on interoception

Mindfulness practices, such as the body scan, could enhance interoception. While prior research shows promise for its effects on interoceptive sensibility (IS; subjective experience of bodily cues) and accuracy (IAcc; accurate detection of bodily signals), studies often use a limited set of interoceptive variables or apply small samples. In two pre‐registered randomized trials, we examined a 2‐week daily auditory body scan intervention vs. active control (guided imagery; Study 1) or passive control (Study 2). Study 1 included N = 85 participants ( M age = 22.26, 71% women), randomized to body scan or guided imagery. Study 2 included N = 90 participants ( M age = 23.05, 80% women), randomized to body scan or passive control. IAcc was measured pre‐ and post‐intervention using the heartbeat tracking task (HTT) and heartbeat discrimination task (HDT), while IS was assessed via confidence ratings and the multidimensional assessment of interoceptive awareness (MAIA‐2). Study 1 showed significant time effects for IAcc (HTT: p < .001; HDT: p = .012), confidence ratings ( p 's < .001), and MAIA‐2 ( p < .001). Study 2 found improvements following the body scan for IAcc (HTT: p = .050), confidence ratings (HTT: p = .006; HDT: p = .0496), and MAIA‐2 ( p = .003). Findings suggest that body scan enhances interoception within two weeks, though guided imagery and similar approaches may yield comparable effects.
