Abstract
OBJECTIVE: To examine the effects of reading exercise-related magazine articles (health, appearance, or control) and the moderating effects of exercise self-identity on reasons for exercise and perceptions of attractiveness, among women in first year university. An additional purpose was to use a thought listing technique, the results of which were examined for evidence of internalization of the exercise-related messages. PARTICIPANTS: Female students in their first year of studies between September 2010 and April 2011 (N = 173; mean age = 19.31 years, mean body mass index = 22.01).Entities:

Final thought listing codes reflecting the processing of the messages, their definitions, example quotes and number of comments by health and appearance conditions.
| Code | Definition | Example quote | Health | Appearance | Total |
| Case for healthy fat | Belief that thin does not equal healthy, thatfat people can be healthy and thinpeople unhealthy | Having a little extra fat may be healthy. | 31 | 0 | 31 |
| Case against healthy fat | Disbelief that being overweight or fat canin any way be healthy | I am shocked that some people are arguingthat extra fat is healthy. | 9 | 0 | 9 |
| Fitness is key; sizedoesn’t matter | Health has nothing to do with body weight,health depends on fitness | Fitness is more important than weight. | 63 | 2 | 65 |
| No solution to argumentof healthy fat | Both sides of the healthy/unhealthy fat arepresented with participant not sure whatto believe | I don’t think there will be a clear-cut solutionto the problem size vs health. | 18 | 0 | 18 |
| Motivated to try exercisesor changeappearance | Reading article motivated reader to be activeand to improve her appearance | Those seem like good exercises-Ishould try them! | 0 | 38 | 38 |
| Not motivated to tryexercises or changeappearance | Rejection of the message in the appearancearticle − reader does not want to“waste her time” doing the exercises or themessage is unrealistic | I wouldn’t put that muchwork into my bum. | 0 | 20 | 20 |
| Issues surroundingobese people | Comments only about obese people thatreflect the idea that by saying fat can be healthyit justifies people being “lazy” | Accepting “its ok to be fat” gives lazy,overweight people the idea that its ok notto exercise/eat healthy. | 19 | 0 | 19 |
| Media targets women | Messages in the media target women andmen are exempt from similar messages | pressure from peers or media everyday thatsay women must be “model” thin, otherwiseyou are not beautiful enough. | 9 | 26 | 35 |

| Summarizing Article | Participant just gave a summary with noadditional analysis or comments. | Workout 3–4 times a week, with at least oneday off between workouts. | 3 | 10 | 13 |
