The goals of the study were (1) to determine the association between parental and offspring suicidal ideation and suicide attempts among adult offspring in a general community sample, and (2) to examine the extent to which this association can be explained by mediating processes of mental disorders. Data were drawn from the National Comorbidity Survey (n=8098), a representative household sample of adults aged 15–54 in the United States. The relationships between suicidal ideation and suicide attempts among adult offspring and suicidal ideation and suicide attempt in their parents, compared with those in parents not characterized by suicidal ideation or suicide attempts, were calculated using multiple logistic regression analyses. Analyses were adjusted for differences in sociodemographic characteristics and for mental disorders. Results showed that parental suicidal ideation was associated with a significantly increased likelihood of suicidal ideation [OR=1.7 (1.2, 2.5)] and suicide attempt [OR=1.4 (0.9, 2.1)] among offspring. Parental suicide attempt was associated with increased odds of suicidal ideation [OR=2.0 (1.4, 2.9)] and suicide attempt [OR=2.2 (1.4, 3.4)] among offspring. Comorbid mental disorders contributed to the strength of these associations, but with the exception of the link between parental suicidal ideation and offspring suicide attempt, all remained statistically significant even after adjustment. These data provide initial evidence of familial linkages (parent-offspring) of suicidal ideation and behavior among a sample of adults representative of the US population. The data suggest that comorbid mental disorders contribute to these associations but do not completely account for them. The findings are consistent with and extend results from family, clinical, and high-risk studies suggesting that a familial risk of suicidal ideation and suicide behavior occurs in the general population. Implications for prevention and future research are discussed. [Copyright &y& Elsevier]

The objective of this study was to replicate previous findings indicating that early-onset panic attack (≦20 years) with fear represents a possible prodrome of early-onset severe psychopathology. Data were drawn from the Epidemiologic Catchment Area Survey (ECA) (n=20 291), a household sample of adults aged 18 and older drawn from five cities in the United States. Multivariate logistic regression analyses were used to differentiate those with early-onset panic attacks with fear from those with other panic attacks (early-onset without fear, late-onset without fear, late-onset with fear) with regard to psychiatric comorbidity, age at onset of comorbid mental disorders, and suicidal ideation and suicide attempts. Results of statistical analyses revealed that early-onset fearful panic attack (n=368) was associated with increased likelihood of major affective and substance use disorders, significantly earlier onset of comorbid mental disorders, higher rates of suicidal ideation and suicide attempt, and higher rates of antisocial personality disorder compared with those with other subtypes of panic attacks. Multiple logistic regression analyses showed that early-onset fearful panic was independently associated with increased odds of major depression [OR=3.0 (2.6, 3.5)], bipolar disorder [OR=7.9 (5.7, 10.8)], antisocial personality disorder [OR=1.5 (1.3, 1.7)], agoraphobia [OR=1.2 (1.1, 1.4)], simple phobia [OR=1.6 (1.4, 1.8)], and alcohol dependence [OR=1.3 (1.2, 1.5)], compared with those with all other panic attacks. These findings are consistent with previous epidemiologic data and provide new evidence to suggest that early-onset fearful panic attack may be a marker of increased vulnerability to severe and persistent psychopathology and associated with high rates of suicidality.
