Fig. 1 Pre-test distributions of well-being and ill-being measures.

Fig. 2 Relationships between several well-being and ill-being measures. A small amount of jitter has been added to the points to see the relationships more clearly.

Fig. 3 Differences between post-test and pre-test scores for several well-being and ill-being measures.

Table 2 ANOVA contrast results comparing changes in well-being and ill-being measures across treatment groups.
