The Applied Mindfulness Process Scale (AMPS) is a measure that assesses the use of mindfulness skills in daily life. The scale is ideally used during or after a mindfulness-based intervention. It consists of 15 items that can be rated on a five-point Likert scale and measures three different domains, namely, decentering, positive emotion regulation, and negative emotion regulation. The AMPS was developed and validated using qualitative and quantitative techniques. It exhibits excellent reliability and nomological validity, correlating positively with well-being scales and negatively with measures of distress. Moreover, it has incremental validity accounting for variance in outcome measures beyond the explanatory power of other mindfulness measures. Preliminary research findings indicate that the scale is sensitive to changes in mindfulness. However, the AMPS is a relatively new scale, and more research is needed that uses the scale in mindfulness-based intervention research.
