Connectedness to Nature Scale
Also known as: CNS, Mayer-Frantz Connectedness
The Connectedness to Nature Scale (CNS) measures the degree to which individuals feel emotionally and cognitively connected to nature as part of their sense of self. Developed by Mayer and Frantz (2004), the CNS operationalizes the construct of nature connection—the felt sense of kinship, interdependence, and belonging with the natural world. The scale is widely employed in environmental psychology research, health outcome studies examining nature exposure effects, and intervention evaluations designed to strengthen human-nature relationships.

When to use it
Use the CNS when evaluating outcomes of nature-based interventions (outdoor therapy, forest bathing, nature education), assessing whether individual differences in nature connection mediate health benefits from nature exposure, comparing nature affinity across populations or life stages, tracking changes in felt connection following environmental experiences, and predicting intrinsic motivation for conservation. Also valuable in understanding why some individuals spontaneously adopt pro-environmental behaviors while others do not—connection often precedes behavior. Commonly paired with outdoor activity measures or ecosystem knowledge to distinguish felt connection from engagement or competence.
Strengths & limitations
- Strong theoretical grounding in biophilia hypothesis and self-determination theory; captures affective and identity dimensions of human-nature relationship beyond behavioral or knowledge-based measures
- Reliable psychometric properties with good internal consistency (Cronbach's α = 0.81–0.84) and test-retest stability (r = 0.76–0.83 over 4-6 weeks)
- Documented associations with psychological well-being, life satisfaction, and mental health; higher CNS scores predict lower depression, anxiety, and stress symptoms independent of outdoor activity frequency
- Sensitive to intervention effects; demonstrates measurable change following nature exposure, mindfulness-in-nature training, and environmental education programs
- Culturally adaptable with validated translations in 15+ languages, enabling cross-national research on nature connection across diverse ecosystems and human populations
- Measures felt connection and affinity, not actual behavior or environmental knowledge; high CNS scores may reflect nature-focused identity without corresponding conservation action
- Potential social desirability bias, particularly in environmentally conscious samples or contexts where pro-nature responses are normative or expected
- May be influenced by recent nature exposure experience; respondents who recently spent time in nature may rate themselves higher temporarily, requiring baseline assessment prior to interventions
- Limited dimensional differentiation—the 14 items blend affective connection, identity integration, and sense of kinship without clear subscales, making it difficult to isolate which aspect of connection drives outcomes
Frequently asked
How does CNS differ from the New Ecological Paradigm (NEP) Scale?
NEP measures abstract beliefs about the environment and ecological limits (worldview); CNS measures felt, affective connection to nature (identity and emotion). Someone can score high on NEP (ecocentric beliefs) but low on CNS (minimal felt kinship), or vice versa. Use both scales to assess both cognitive orientation and emotional integration.
Can CNS predict whether someone will recycle or reduce their carbon footprint?
CNS predicts intrinsic motivation for conservation (r = 0.35–0.50) and general pro-environmental intentions, but actual behavior prediction is moderate. Combine CNS with measures of behavioral intention, perceived behavioral control, and situation-specific barriers for stronger behavior forecasting.
Does nature exposure immediately increase CNS scores, or does real change take longer?
Single nature exposure sessions may produce temporary emotional elevation but do not reliably shift CNS identity-level scores. Sustained practice (regular outdoor time over weeks to months) or intensive interventions (wilderness therapy programs, mindfulness-in-nature training) drive lasting CNS change. Assess baseline before intervention and retest 4–8 weeks post-intervention to capture meaningful shifts.
Are there cultural differences in CNS interpretation?
Nature conceptualization varies culturally—some cultures emphasize nature as resource, others as sacred or relational. CNS scores tend to be higher in populations with strong traditional ecological knowledge and outdoor lifestyle access, and lower in highly urbanized populations with limited nature contact. Use culture-specific norms and examine item endorsement patterns (not just total score) to understand how nature connection is culturally expressed.
