Background Although there has been a tremendous amount of research examining the risk conferred for suicide by depression in general, relatively little research examines the risk conferred by specific forms of depressive illness (e.g., dysthymic disorder, single episode versus recurrent major depressive disorder [MDD]). The purpose of the current study was to examine differences in suicidal ideation, clinician-rated suicide risk, suicide attempts, and family history of suicide in a sample of outpatients diagnosed with various forms of depressive illness. Methods To accomplish this aim, we conducted a cluster analysis using the aforementioned suicide-related variables in a sample of 494 outpatients seen between January 2001 and July 2007 at the Florida State University Psychology Clinic. Patients were diagnosed using DSM-IV criteria. Results Two distinct clusters emerged that were indicative of lower and higher risk for suicide. After controlling for the number of comorbid Axis I and Axis II diagnoses, the only depressive illness that significantly predicted cluster membership was recurrent MDD, which tripled an individual’s likelihood of being assigned to the higher risk cluster. Limitations The use of a cross-sectional design; the relatively low suicide risk in our sample; the relatively small number of individuals with double depression. Conclusions Our results demonstrate the importance of both chronicity and severity of depression in terms of predicting increased suicide risk. Among the various forms of depressive illness examined, only recurrent MDD appeared to confer greater risk for suicide.

Recent years have seen an increase in emphasis on the use of psychological treatments that are supported by empirical data, as advocates have argued these treatments lead to better patient outcomes. We have previously shown that a shift to use of empirically supported treatments in a training clinic led to significant improvement in patient outcomes over four year « (Cukrowicz et al., 2005). In the current study, we examined whether average patient outcomes at termination continued to be favorable over the six-year period following the initial shift. We examined data from 549 patients (M age = 25.78, SD = 10.08: 322 females and 227 males) treated prior to and after the shift to empirically supported treatments, all of whom were rated after termination using the Clinical Global Impression rating scale to track their improvement during treatment. The cunent study found that improvements in patient outcomes continued over the six-year follow-up period. Patients treated during the follow-up period had superior outcomes when compared to those treated following the initial shift to empirically supported treatments (effect size = .28, p < 05) and when compared to those treated prior to the shift to empirically supported treatments (effect size = 1.83, p < .001). Thus, this study points both to the efficacy of empirically supported treatments in clinical practice and to the feasibility of implementing and successfully maintaining EST use in a training clinic setting. f'..

Prior studies have demonstrated that events causing displacement from parents—such as parental death, abandonment of the adolescent, or divorce—represent a risk factor for adolescent suicide, but research to date has not established a theoretical model explaining the association between parental displacement and adolescent suicidal behavior. The current studies examined the construct of failed belonging proposed by the interpersonal theory of suicide as one factor that may link parental displacement with adolescent suicide. Study 1 found that low levels of belonging mediated the association between parental displacement and adolescent suicide attempts in a large urban community sample of older adolescents between the ages of 18 and 23. In Study 2, parental displacement interacted with low belonging to predict suicide attempts, such that adolescents (average age 16.6 years; (SD = 1.2) who experienced both displacement and low levels of belonging had the highest risk for suicide.
