Cognitive and Affective Mindfulness Scale (CAMS)
Also known as: CAMS, CAMS-R
The Cognitive and Affective Mindfulness Scale (CAMS) is a 12-item trait mindfulness measure designed to assess the degree to which individuals are present, aware, and non-judging toward their internal (cognitive and emotional) and external experiences. Developed by Feldman, Hayes, and colleagues at Rutgers University and published in the Journal of Clinical Psychology in 2007, the CAMS emphasizes the emotional and cognitive regulation aspects of mindfulness, particularly the capacity to observe thoughts and feelings without judgment. The CAMS-Revised (CAMS-R, 2006) is the refined version, offering strong brevity and psychometric properties that make it especially useful in clinical settings where time and assessment burden must be minimized.

When to use it
The CAMS-R is optimal for: (1) acceptance and commitment therapy (ACT) trials where psychological flexibility (involving non-judgment and present-moment awareness) is the theoretical mechanism; (2) emotion-focused and acceptance-based interventions evaluating whether increased emotional awareness and reduced judgment predict symptom change; (3) clinical populations with anxiety, depression, or emotion dysregulation where non-judgmental emotional awareness is therapeutic goal; (4) research prioritizing assessment brevity without sacrificing multidimensional structure. The CAMS-R is less appropriate for populations requiring detailed facet-level mindfulness understanding (FFMQ offers more detail) or for state-level measurement.
Strengths & limitations
- Optimal brevity-comprehensiveness balance: 12 items with four meaningful subscales provide multidimensional assessment without excessive burden—shorter than FFMQ or KIMS while capturing distinct aspects.
- Emotion regulation focus: emphasis on non-judgment and awareness of emotional experience makes the CAMS-R particularly relevant for clinical populations and emotion-focused interventions.
- Strong ACT alignment: the four-factor model directly maps onto ACT theoretical targets (attention, present-moment orientation, cognitive awareness, acceptance of inner experience).
- Responsive to intervention: CAMS-R shows robust sensitivity to acceptance-based and mindfulness-based interventions, with typical effect sizes medium to large.
- Limited novelty: the CAMS-R is newer than FFMQ and MAAS and has undergone less extensive validation and norming across diverse populations.
- Subscale intercorrelation: the four subscales intercorrelate moderately (r = 0.40–0.60), suggesting some redundancy in measurement or difficulty in fully separating the four factors.
- Population representation: normative data are less extensive than for FFMQ; many studies lack clear reporting of CAMS-R norms for specific populations.
- Limited research base for clinical cutoffs: unlike FFMQ or MAAS, well-established clinical cutoffs for distinct mindfulness/non-mindfulness profiles do not exist for CAMS-R.
Frequently asked
Is the CAMS-R better than the FFMQ for my study?
Choose CAMS-R if: (1) you prioritize assessment brevity (12 vs. 39 items); (2) your intervention targets emotional awareness and acceptance specifically (ACT, emotion-focused therapy); (3) you need a simpler scoring structure. Choose FFMQ if: (1) you need multidimensional depth (five vs. four factors); (2) you want more extensive normative comparison data; (3) your population is non-clinical or meditation-focused. Both are valid; the choice is research-design dependent.
My participant scored 22 total CAMS-R (moderate) but 3 on Non-Judgment (low). What does this mean?
This profile indicates the participant has moderate overall mindfulness but struggles specifically with non-judgmental observation of internal experience—they likely notice and attend to thoughts and feelings but criticize or evaluate them. Therapeutically, prioritize acceptance-focused interventions (mindful observation of difficult thoughts without changing them) to build Non-Judgment capacity.
Can CAMS-R detect state changes within a single meditation session?
The CAMS-R is designed for trait measurement and post-intervention assessment; its four-factor structure and retrospective phrasing ('I pay attention to...') make it less sensitive to momentary state changes. Use the Toronto Mindfulness Scale (post-meditation state assessment) for within-session changes. The CAMS-R is better suited for pre-post intervention outcome measurement.
Is the CAMS-R appropriate for adolescents?
Limited adolescent validation exists for the CAMS-R. The construct complexity and abstract language may exceed developmental capacity of early adolescents (<14 years). Consider child-adapted measures (CAMM, CAMI-A) for youth; the CAMS-R is reasonable for mid-late adolescents (15+) with adequate reading/reflection skills.
