Mindfulness and Emotion Regulation: The Development and Initial Validation of the Cognitive and Affective Mindfulness Scale-Revised (CAMS-R)

Abstract

As interest grows in mindfulness training as a psychosocial intervention, it is increasingly important to quantify this construct to facilitate empirical investigation. The goal of the present studies was to develop a brief self-report measure of mindfulness with items that cover the breadth of the construct and that are written in everyday language. The resulting 12-item measure demonstrated acceptable internal consistency and evidence of convergent and discriminant validity with concurrent measures of mindfulness, distress, well-being, emotion-regulation, and problem-solving approaches in three samples of university students. To address potential construct contamination in two items, data are also presented on an alternate 10-item version of the measure.

Notes

  1. 1.

    There is considerable evidence that under- and over-engagement can and do co-occur. Individuals with little skill in regulating emotions may vacillate between under- and over-engagement. In addition, individuals can use over-engagement as a form of avoidance. Excessive worry may be a means of distracting oneself from more upsetting topics (Borkovec, 1994). Similarly, rumination has been conceptualized as a means of distracting one's self from one's actual life problems (Jacobson, Martell, & Dimidjian, 2001). There is also recent evidence that thought suppression prospectively predicts increased rumination for individuals experiencing a high degree of life stress (Wenzlaff & Luxton, 2003). Thus, under- and over-engagement are not necessarily mutually exclusive. However, these broad categorizations are used here to organize the criterion measures and the discussion of them.

  2. 2.

    In this way, there is considerable overlap with an alternative conceptualization of mindfulness developed by Ellen Langer and colleagues (Langer, 1989), which involves both paying attention to one's environment, actively viewing situations from multiple perspectives, and responding in novel ways. This conceptualization, however, departs somewhat from Eastern notions of mindfulness that inform clinical interventions, which tend to emphasize “allowing” thoughts to pass through the mind rather than actively manipulating them.

  3. 3.

    Because one of the questionnaires of interest (MAAS) was made available once the study was underway, it was administered to a subsample of participants who joined the study in a second recruitment wave. The Distraction subscale of the RSQ was also added to the protocol at this time.

  4. 4.

    Each Steiger's (1980) z-test was performed on the subsample that completed the CAMS-R and both criterion measures of interest for that analysis.
