The conclusions drawn by the authors appear to rest on three main findings. First, suicide attempters reported significantly greater subjective depression, hopelessness, and suicidal ideation than nonattempters. The significance of this difference was tested by use of the t test, which assumes that the data are normally distributed. However, in the authors’ Table 1, it is readily apparent that for the measures of hopelessness and suicidal ideation, the standard deviation multiplied by two is greater than the mean. This indicates that the mean is unlikely to be the center of the distribution, and for data that do not follow a normal distribution, appropriate nonparametric tests ought to be used (3).
