Design outcomes

Primary

MeasureTime frame
Improvement in employees’ implicit connection with nature The outcome will be assessed using a computer-based self-administered cognitive assessment: Implicit Association with Nature (IAN). [The outcome will be measured at 3-time points: baseline (prior to the commencement of intervention), 2 months after the baseline and 5 months after the baseline.] Improvement in explicit connection with nature The outcome will be assessed using a Sinhala version of the Connectedness to Nature Scale (CNS-Sin) which was validated to a Sinhala-speaking context as a part of this PhD work [The outcome will be measured at 3-time points: baseline (prior to the commencement of intervention), 2 months after the baseline and 5 months after the baseline.] Reduction in per capita carbon footprint associated with food and beverage consumption The outcome will be assessed using self-reported Carbon emissions data i.e. data collection sheets were piloted under the PhD work [The outcome will be measured at 3-time points: baseline (prior to the commencement of intervention), 2 months after the baseline and 5 months after the baseline.] Reduction in per capita carbon footprint associated with energy consumption at residence The outcome will be assessed using self-reported Carbon emissions data i.e. data collection sheets were piloted under the PhD work [The outcome will be measured at 3-time points: baseline (prior to the commencement of intervention), 2 months after the baseline and 5 months after the baseline.] Reduction in per capita carbon footprint associated with travel behaviour The outcome will be assessed using self-reported Carbon emissions data i.e. data collection sheets were piloted under the PhD work [The outcome will be measured at 3-time points: baseline (prior to the commencement of intervention), 2 months after the baseline and 5 months after the baseline.] Reduction in per capita carbon footprint associated with solid waste disposal at residence The outcome wil

Secondary

MeasureTime frame
Improvement in trait mindfulness The outcome will be measured using a Sinhala version of Five Facet Mindfulness scale which was translated and judgmentally validated by a member of the AHEAD 81-research team The outcome will be measured at 3-time points: baseline, 2 months after the baseline and 5 months after the baseline [The outcome will be measured at 3-time points: baseline (prior to the commencement of intervention), 2 months after the baseline and 5 months after the baseline.] Associations between meditation experience, trait mindfulness and green life i.e. connectedness to nature, per capita carbon footprint. The aforementioned validated tests under the primary outcomes will be used in measuring variables under this outcome [The outcome will be measured at 3-time points: baseline (prior to the commencement of intervention), 2 months after the baseline and 5 months after the baseline.]
