  1. a Seven-point ordinal scales consisted of 6 steps; each two steps comprised one-third of the scale. For example, for a unipolar scale, the lower third (LOW) = 1–3, mid-third (MOD) = 3.01–5, and the highest, most positive third (HIGH) = 5.01–7. The full scale was used in the analyses
  2. b Unipolar scale (1 to 7; 4 is the scale midpoint)
  3. c Bipolar scale (−3 to 3; 0 is the scale midpoint)
