Two new questionnaires, the Nondual Awareness Dimensional Assessment-Trait (NADA-T) and the Nondual Awareness Dimensional Assessment-State (NADA-S), were developed to measure nondual awareness—a sense of oneness or absence of self-other boundaries. Principal component analysis with 528 participants identified two dimensions of the NADA-T: self-transcendence and bliss. Further analyses in three independent samples (totaling 725 participants) showed both dimensions reflect a single overarching nondual awareness construct. The NADA-T correlated with interdependent self-construals and dispositional mindfulness.
The Mindful Attention Awareness Scale (MAAS) is a valid and reliable tool for measuring mindfulness in people who have recovered from a first episode of psychosis. In a sample of 150 individuals, the scale showed a single-factor structure that remained stable over time, excellent internal consistency, and expected relationships with measures of well-being, depression, and positive symptoms. These psychometric properties match those found in other populations, supporting the MAAS's use for assessing present-moment attention and awareness in this group.
