In this study, we examined whether nonattachment, a relatively new construct in the mindfulness literature, showed convergent, discriminant, and incremental validity in relation to the well-studied 5 facets of mindfulness. Mindfulness was defined as a multifaceted construct including observing, describing, acting with awareness, nonjudging, and nonreactivity; and measured using the recently validated, 20-item Five Facet Mindfulness Questionnaire (FFMQ; Tran, Glück, & Nader, 2013; Baer, Smith, Hopkins, Krietemeyer, & Toney, 2006). Nonattachment was defined as a flexible, balanced way of relating to one’s experiences without clinging to or suppressing them, and measured using the 7-item Nonattachment Scale (NAS-7; Elphinstone, Sahdra, & Ciarrochi, 2015; Sahdra, Shaver, & Brown, 2015). In a large nationally representative sample of Americans (N = 7,884; 52% women; age, M = 47.9, SD = 16), nonattachment was positively related to all 5 aspects of mindfulness. Structural equation modeling showed that the 20-item FFMQ and NAS-7 showed good fit; their factor structures were invariant across genders and age groups; and NAS-7 was empirically distinguishable from the 5 mindfulness facets. Hierarchical regression models provided evidence of the incremental validity of NAS-7. Finally, mediation models showed that nonattachment substantially mediated the links between the mindfulness facets and the outcome variables of satisfaction with life and life effectiveness.
