Subclaims¶

q3 i? Personality changes from digital VPC interventions were sustained or even amplified at three-month and one-year follow-ups, without signs of fadeout. → Mathias Allemand 2026 q2 i? In a two-week digital coaching program (N = 255), improvements in the self-selected trait were maintained for up to six weeks post-intervention. → Mathias Allemand 2026 (2)

q3 · i? · review · r3

The review reports follow-up studies of the PEACH trial showing changes "sustained—or even amplified" at three months and one year, suggesting volitional personality changes from digital interventions "can be enduring rather than transient", though one-year completers differed somewhat from dropouts.

"Personality changes were sustained—or even amplified—at three-month (Stieger et al., 2021) and one-year follow-ups (Stieger et al., 2024)."

q2 · i? · theoretical · r3

The review reports, citing Stieger et al. (2020a, b), a two-week digital coaching program (N = 255) with daily text messages, psychoeducation, self-reflection tasks, and personalized feedback; most participants selected the trait on which they initially scored lower.

"Greater improvements were observed in the self-selected trait, as reflected in both self-reports and observer-reports, and these changes were maintained for up to six weeks post-intervention."
