About this study
The JArDinS study is a quasi-experimental research that aimed at assessing the impact of community garden participation (a natural experiment) in the adoption of more sustainable lifestyles.
Read the detailed description
The JArDinS study is part of the SURFOOD-Foodscapes project evaluating the relationships between urban foodscape and food styles in Montpellier Metropole (France).
JArDinS consists of a pretest-posttest quasi-experimental research and includes an experimental group of new gardeners starting gardening in a community garden in Montpellier and a control group comprising participants from a survey on food behaviors undertaken as part of SURFOOD-Foodscapes project. Participants will be surveyed at enrollment and 12 months later.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Food diary supplyBehavioural
Each participant was issued with a food supply diary to record details of their household food supply and related trips over 1-mo period. Household food supply included food purchases, food gift/donation, and potential crops from the garden. Away-from-home food consumption was not recorded. For each food purchase, participants provided details of date, place of purchase, foods purchased (name, quantity and expense incurred), and trip made (origin/where the trip started, destination/where the trip ended, and mode of transportation). When till receipts were available in grocery stores or supermarkets, participants were asked to collect them in an envelope placed at the end of the food supply diary. To facilitate data entry, all family members were encouraged to help filling out the diary.
ActigraphBehavioural
Participants were instructed to wear a triaxial accelerometer (wGT3X-BT or wActiSleep-BT, Actigraph, Pensacola, FL, USA) fitted with an elastic strap on right side of the hip for 9 consecutive days, except for bathing and performing activities in the water. The Actigraph was accompanied by an activity logbook in which participants were required to daily record time when awake and sleeping, and, if any, time and duration of workout or device removal
QuestionnaireBehavioural
Participants received by email a link to complete an online questionnaire about mental and social health, sensibility to food waste, and connection with nature
| Study group | Role | What they receive |
|---|---|---|
| Experimental group | Gardeners starting gardening in a community garden in Montpellier (France) Receives: Behavioral: Food diary supply; Behavioral: Actigraph; Behavioral: Questionnaire | |
| Control Group | Volunteers living in the same neighborhoods but with no experience in community gardening. Receives: Behavioral: Food diary supply; Behavioral: Actigraph; Behavioral: Questionnaire |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in healthiness of household food supply
The nutritional quality of household food supply was estimated using two indicators of nutritional quality : the mean adequacy ratio (MAR) and the mean excess ratio (MER)
Measured: at baseline and exactly 12 month later
Change in physical activity energy
Physical activity energy expenditure were estimated directly from raw triaxial accelerometry data using a model which combines an automatic activity-recognition algorithm with an activity-specific count-based model
Measured: at baseline and exactly 12 month later
Change in mental well-being
Assessed by the Warwick-Edinburgh Mental Wellbeing Scale. WEMWBS is a 14-item scale rated on a 5-point Likert-type, in which all items are worded positively and address aspects of positive mental health. Total score range from 14-70, with higher scores indicating a higher level of mental well-being.
Measured: at baseline and exactly 12 month later
Change in social isolation
Assessed by the UCLA Loneliness Scale. UCLA-3 is a 20-item scale (11 positive and 9 negative) rated on a 4-point Likert-type. Total score range from 20-70, with higher scores greater feelings of loneliness.
Measured: at baseline and exactly 12 month later
Change in environmental impact of household's food supply
Greenhouse gas emissions (in g CO2eq), atmospheric acidification (g SO2eq) and marine eutrophication (in g Neq) related to household's food supply were computed using estimates from the French 'SUStable' table.
Measured: at baseline and exactly 12 month later
Change in environmental impact of household's food trip (in g CO2eq)
For each food trip, the distance traveled specifically for food purchase will be multiplied by energy source consumption of the transportation used, and by the corresponding GHGE factor of source consumption. GHGE related to food trip will be calculated as the sum of all food trips during the period of data collection.
Measured: at baseline and exactly 12 month later
Change in sensibility to food waste
Assessed by the Sensibility to food waste scale, a 8-item scale rated on a 7-point Likert-type, that measure in which extent participants attach importance to waste and are emotionally affected by it. Total score range from 7-56, a higher total scores denote greater sensibility to food waste.
Measured: at baseline and exactly 12 month later
Change in connection with nature
Affective, cognitive, and experiential aspects of individuals' connection to nature was assessed by the Nature Relatedness Scale (NRS). NRS is a 21-item scale rated on a 5-point Likert-type. Total score range from 5-105, a higher total scores denote greater nature connectedness.
Measured: at baseline and exactly 12 month later
Change in household food supply expenditure
Monthly household food expenditure and the contribution of each food group and subgroup to total food expenditure were estimated using food expenses data collected in the food supply diary.
Measured: at baseline and exactly 12 month later
Secondary outcomes (5)
Age (in year) of each member of the household
Participants were asked to report the age of each member each adult of the household.
Measured: at baseline
Gardening experience prior to the project
Participants were asked about their experiences and perceived competence in gardening.
Measured: at baseline
Gender of each member of the household
Participants were asked to report the gender of each adult of the household
Measured: at baseline
Household income
Participants indicated their net income bracket of the household (by month).
Measured: at baseline
Education level of each adult of the household
Participants were asked to report the higest education level achieved by each adult of the household.
Measured: at baseline

Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in healthiness of household food supply (time frame: at baseline and exactly 12 month later). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03694782, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Feb 2020.
