The aim of this dissertation was to examine the Five Facet Mindfulness Questionnaire (FFMQ; Baer, Smith, Hopkins, Krietemeyer, & Toney, 2006) with Item Response Theory (IRT). Mindfulness is conceptualized as both a trait and a state and has different operationalized definitions. The FFMQ measures mindfulness as a trait. This measure was created through combining five existing measures of mindfulness and performing an exploratory factor analysis to remove extraneous items (Baer et al., 2006). The resulting measure is 39 items and consists of five mindfulness factors, or facets: Observing, Describing, Acting with Awareness, Nonjudging, and Nonreacting. Each of these facets are composed of items assessing one's ability to observe, describe, act with awareness, be nonjudgmental of, and be nonreactive to one's thoughts, feelings, sensations, and experience (Baer et al., 2006). The FFMQ has been found to be a generally reliable and valid measure of trait mindfulness (e.g., Baer et al., 2008). However, it is not without faults and some inconsistencies in its psychometrics. For instance, the Observing facet is inconsistent in its correlations with other constructs and as confirmatory factor, particularly in non-meditating samples (e.g., Baer et al., 2006; Baer et al., 2008). Additionally, two of the facets, Act with Awareness and Nonjudging, are composed of entirely negatively worded items, and the presence of mindfulness is not necessarily equal to the absence of mindlessness (e.g., Grossman & Van Dam, 2011). Similarly, those who are more mindful may have increased meta-cognitive awareness, which may lead to a different self-report of mindfulness levels than a meditation naive sample (e.g., Grossman & Van Dam, 2011). This study examined each facet with an IRT approach to assess for item difficulty as well as item discrimination between differing trait levels (de Ayala, 2009). Archival data consisting primarily of college students was utilized in addition to the collection of data from a local meditation center via social media, yielding a sample size of 853 participants. After comparing a One Parameter Graded Response Model (1P-GRM) to a Two Parameter Graded Response Model (GRM), the GRM analysis provided a better fit. The GRM analyses revealed 15 items which were poorly functioning and removed. This created a stronger revised 24-item version of an FFMQ. Future research should focus on replicating these results via an IRT approach, examine differential item functioning via an IRT approach, and compare this revised mindfulness measure to an implicit measure of mindfulness.
