Table 1. Overview of sample sizes (N) in each category. Ntotal indicates the number of questionnaires, nvalid indicates the sample size after listwise deletion (per scale).
Table 3. Items of the interest in species conservation scale and factor loadings for each subsample.
Table 4. Items of the Environmental Motives Scale by Schultz (Citation2001) (shortened) and factor loadings (pattern matrix) for adults and children (T1, T2). Values below 0.3 are not shown.
Table 6. Items of the biodiversity loss attitude scale (inspired by Christensen and Knezek Citation2015 and factor loadings (pattern matrix) for each subsample.
Table 2. Results of factor analysis. The three highest eigenvalues for children and adults, T1 and T2, of interest in species conservation, biodiversity loss attitude, and environmental concern, and the variance (var.) they each explain.
Table 5. Cronbach’s α for the three factors biospheric, egoistic, and altruistic concern in each subsample.
