Data collection was based on in person interviews conducted
in several regions of France among a convenience sample.
Surveyors let interviewees fill the questionnaire helping them
in case of difficulty. Surveyors were not informed of the trueobjective of the survey. Only five incomplete questionnaires
were removed. The final sample (n 468) is diversified in
terms of gender (55 per cent of males), age (mean 38.3;
SD 13.7, minimum 18, maximum 87) and educational
level (no formal education: 2.5 per cent; vocational
qualification: 14.2 per cent; high school degree: 19.9 per cent;
high school degree 2 years: 19.5 per cent; high school degree
3/4 years: 28.1 per cent; Masters or PhD: 15.9 per cent).
This diversity is important to avoid artificial correlations due
to a possible relationship between these variables and
environment concern, even if the literature is inconclusive
(Honnold, 1984; Arcury and Johnson, 1987; Zelezny et al.,
2000).
