Description: The Applied Mindfulness Process Scale (AMPS) is a tool designed to measure how individuals apply mindfulness skills during and after a mindfulness-based intervention (MBI). It was initially developed and validated in individuals with mindfulness experience and in good health, but its utility in clinical populations has not been fully examined. This study tested the reliability, nomological validity, and incremental validity of the AMPS in a sample of 100 women with substance use disorder (SUD) engaged in an MBI. The AMPS and its subscales demonstrated adequate internal consistency reliability (Cronbach’s alpha range = 0.80–0.97) at each assessment, with test-retest reliability correlations ranging from small to moderate (Spearman’s ρ = 0.22–0.74). AMPS scores averaged across assessments correlated with conceptually related measures in expected directions at post-intervention (e.g., Five Facet Mindfulness Questionnaire, r = 0.44, p < 0.01; Perceived Stress Scale, r = −0.30, p < 0.01; Difficulties with Emotion Regulation Scale, r = −0.48, p < 0.01). The AMPS also explained variance in emotion dysregulation beyond traditional mindfulness measures, such as class attendance and practice effort, at post-intervention (β = −0.32, p < 0.05). These findings suggest that the AMPS broadens the capacity to capture behavioral aspects of therapeutic change distinct from conventional mindfulness measures. Factor analytic work is recommended for clinical, novice meditator samples to further refine the scale.
