Suicidal thoughts and behaviors are complex phenomenon and their relationship to trait impulsivity remains unclear. Although suicidal thoughts and behaviors are common among emerging adults, the availability and quality of data is scarce in countries like Kenya, due to stigmatization and illegality of suicidal behaviors. This research sought to determine the prevalence of suicidal ideation and suicide attempt in emerging adults in Kenya and examine the role of trait impulsivity. Data from 297 undergraduate students were collected using a sociodemographic questionnaire and the Barratt’s Impulsiveness Scale (BIS-11). Results showed that 15.8% (n = 47) of students reported suicidal ideation only while 8.4% (n = 25) reported suicide attempt. Significant gender differences were observed with females more likely than males to report suicidal ideation and suicide attempts. Higher attentional impulsivity was observed in those with suicidal ideation and attempted suicide than those with no suicidality. These findings help highlight the magnitude of suicidality in Kenya.
