BACKGROUND: There is need for deeper understanding of the processes by which suicidal thoughts lead to action. Examination of morbid ideation and the emotional sequelae of such ideation that may feed suicide ideation (SI) and attempts (SA) have been limited.
METHOD: Adult psychiatric outpatients (N = 385) were administered the Response to Morbid Ideation Questionnaire (RMI-Q) and measures of SI, suicidal thoughts and behaviors (STB), and other psychiatric symptom severity. We examined (1) incidence and prevalence in mentation of morbid ideations and emotional responses to these ideations, (2) differences in emotional responses between individuals of varying levels of suicide history, and (3) the relationships of different types of morbid ideations and emotional responses with concurrent SI and symptom severity.
RESULTS: Morbid ideation was reported by 87.5% of participants and associated with lifetime and concurrent levels of SI/STB. Calm/relieved emotional responses were associated with lifetime and concurrent levels of SI/STB, while negative-valence responses to morbid ideations were associated with concurrent severity of psychopathology.
CONCLUSIONS: Our results suggest that the role of morbid ideation and its emotional sequelae in the development of suicidal motivation and action deserves further attention and may be a treatment target for suicide risk reduction.
