Dr. Cheng stresses that when the news media report cases of suicide, they tend to put forward monocausal theories of people who have been disappointed in love, have lost their job, or are under excessive academic pressure, but in fact very few suicides can be attributed to a single cause.
他強調，傳播媒體在報導自殺個案時，常出現「失戀」、「失業」或「學業壓力」等「單因論」，但其實很少個案是因單一原因而自殺的。
