Complex depression (CD) (high likelihood of previous suicide attempt, interpersonal and social dysfunctions, psychiatric comorbidities, and recurrence). Recurrent depression (RD) (high likelihood of psychiatric comorbidities and recurrence). Single depression (low likelihood of previous suicide attempt, interpersonal, social dysfunction, psychiatric comorbidities, and recurrence).
