Abstract
A preliminary investigation on the effect of low-intensity mindfulness on repetitive negative thinking (RNT) was conducted. Undergraduate students with high ruminative tendencies were randomly assigned into three groups, namely, mindfulness and count RNT in daily life (mindfulness: M), count RNT only (self-monitoring: S), and non-count RNT (control: C) and compared RNT change. Analyses revealed that RNT measured by questionnaire was decreased only in the M group and was lower compared with the S and C groups in the long-term. Both findings present marginal significance. Although RNT count in daily life significantly increased in the S group, the M group demonstrated a decrease with marginal significance. However, there were no correlations between the amounts of change in RNT and mindfulness. Results are consistent with those of previous studies that illustrated that mindfulness procedure decreases RNT.
