Final answer:
The question pertains to a study by Daniel Offer on the self-image of adolescents in various countries, but the specific results are not provided, making it impossible to answer accurately. Self-image in adolescents is complex and influenced by societal, peer, and media factors.
Step-by-step explanation:
When Daniel Offer and his colleagues studied the self-image of adolescents in various countries, including the United States, Australia, Bangladesh, Hungary, Israel, Italy, Japan, Taiwan, Turkey, and West Germany, they discovered that a significant portion of the adolescents displayed a healthy self-image. While the provided information does not specify the exact study by Daniel Offer, or give a direct answer to the percentage in question, generally, we can infer that adolescents across different cultures can have varying degrees of self-image due to a multitude of factors, including societal norms, peer influence, and media representation, as suggested by the provided figure about the influence of thin models on body image.
Unfortunately, without the specific results of Daniel Offer's study, it is impossible to accurately answer this question. However, it's important to acknowledge that self-image among adolescents is a complex subject often researched in the field of Social Studies. This type of work is essential as it can help inform policies and programs aimed at improving the mental health and wellbeing of young people worldwide.
