Parents' ranking of 8 frame styles (See Figure 1 for pictures of the frames).

*#1 indicates the highest ranking receiving a score of 8 and #8, the lowest ranking receiving a score 1. A total score for each frame style was calculated as the sum of points awarded across all participants, which was then divided by the maximum possible score in order to facilitate comparison across groups of different sizes. The maximum possible score was equal to total respondents times 8.
