Tobacco prevention studies show that graphic health warnings are more effective than text warnings, but there are no data on the effectiveness of different types of graphic health warnings in a Pakistani population. Even marginal differences in the effectiveness of genres can be of potential significance for public health.
To study the effectiveness of different types of graphic tobacco warnings in a Pakistani population.
We presented ten anti-smoking warnings to randomly selected volunteers (n = 170) and recorded their opinion on the effectiveness of each warning. The warnings were based on a range of images aimed at the diverse population interviewed. A grading scale based on appeal, application, educational potential and motivation towards cessation was used to produce a composite grade of perceived effectiveness of the warning.
Our results indicate that graphic warnings reach a greater proportion of the population than text warnings. Those appealing to logic, and those inculcating a sense of fear by showing a deleterious outcome of smoking, were judged likely to be most effective in motivating smokers to quit and preventing experimental smokers from forming a habit.
烟草预防研究表明，图形健康警示比文字警示更有效，但在巴基斯坦人群中，还没有关于不同类型图形健康警示有效性的数据。即使不同类型的警示在有效性上存在微小差异，也可能对公共卫生具有重要意义。
研究不同类型的图形烟草警示在巴基斯坦人群中的有效性。
我们向随机选择的志愿者（n=170）展示了十种反吸烟警示，并记录了他们对每种警示有效性的看法。这些警示基于针对接受采访的不同人群的一系列图像。我们使用了一种基于吸引力、适用性、教育潜力和戒烟动机的评分标准，对警示的有效性进行综合评分。
我们的结果表明，图形警示比文字警示能够覆盖更大比例的人群。那些诉诸逻辑的警示，以及那些通过展示吸烟的不良后果来引起恐惧的警示，被认为最有可能有效地促使吸烟者戒烟，并防止实验性吸烟者养成吸烟习惯。
