Objective: The purpose of this study was to determine the lifetime incidence of mental disorders in caregivers involved in maltreatment and in their maltreated child., Methods: Lifetime DSM-III-R and IV psychiatric diagnoses were obtained for 53 maltreating families, including at least one primary caregiver and one proband maltreated child or adolescent subject (28 males, 25 females), and for a comparison group of 46 sociodemographically, similar nonmaltreating families, including one proband healthy child and adolescent subject (22 males, 22 females)., Results: Mothers of maltreated children exhibited a significantly greater lifetime incidence of anxiety disorders (especially post-traumatic stress disorder), mood disorders, alcohol and/or substance abuse or dependence disorder, suicide attempts, and comorbidity of two or more psychiatric disorders, compared to control mothers. Natural fathers or mothers' live-in mates involved in maltreatment exhibited a significantly greater lifetime incidence of an alcohol and/or substance abuse or dependence disorder compared to controls. The majority of maltreated children and adolescents reported anxiety disorders, especially post-traumatic stress disorder (from witnessing domestic violence and/or sexual abuse), mood disorders, suicidal ideation and attempts, and disruptive disorders. Most maltreated children (72%) suffered from comorbidity involving both emotional and behavioral regulation disorders., Conclusions: Families involved in maltreatment manifest significant histories of psychiatric comorbidity. Policies which target identification and treatment of comorbidity may contribute to breaking the intergenerational transmission of maltreatment.

Background: We compared homicide death rates and characteristics of homicide victims and perpetrators in 1966-1974, 1984-1990, 1992-1993, and 1996 in Allegheny County, Pennsylvania, in an attempt to detect possible differences in the pattern of homicides., Methods: Data were obtained from death certificates, coroner's records, police reports and newspapers., Results: In the 1990s the homicide death rate increased for 15- to 24-year-old black men. The rate was 69 per 100,000/year for black men ages 15-24 years from 1966 to 1974 and rose to 275 per 100,000 from 1992 to 1993. Currently, the rates appear to be declining again. Preliminary data from 1996 showed the number of homicide deaths excluding vehicular homicides between 1993 and 1996 to decline from 19 to 8 for white men, from 70 to 42 for black men, from 9 to 3 for white women, and from 13 to 6 for black women with little change in the population (denominator). The dramatic drop from 111 to 61 deaths over a short time is similar to changes across the United State and is characteristic of epidemic rise and fall of homicides in the community., Conclusions: Between 1966 and 1993 Allegheny County experienced two separate homicide epidemics, one between 1966 and 1976 and the other between 1990 and 1993. Epidemics of homicide occur frequently and have different characteristics. New characteristics of the most recent epidemic of homicide include more homicides out of home, among strangers; less association with alcohol; and multiple perpetrators. Drug-use-associated homicides have also increased. Guns are the primary agents of homicide epidemics.

The psychiatric sequelae of loss of a family member to suicide were evaluated in parents and siblings of adolescent suicide victims and controls, who were followed up to 3 years after the suicide. Siblings did not show an increased risk for the development of depression, posttraumatic stress disorder (PTSD), or other conditions over the course of follow-up, despite showing a prolonged elevated level of grief symptomatology. Mothers showed an increased rate of recurrence of depression over follow-up, whereas fathers did not show an increased incidence of disorder compared to fathers of controls. The interrelationship of bereavement and depression for siblings, parents, and others exposed to suicide is discussed.

Sixty-three adolescent suicide victims with a history of affective illness were compared to 23 adolescent community controls with a lifetime history of affective illness, using a case-control design. Suicide victims were more likely to have had major depression, comorbid substance abuse, a past suicide attempt, family history of major depression, treatment with a tricyclic antidepressant, history of legal problems, and a handgun available in the home. There was a non-significant trend for bipolar depression to convey a higher risk for completed suicide than unipolar depression. Recommendations for the prevention of suicide among those with early onset affective illness are discussed in light of these findings.

The risk factors for suicide in adolescents with substance abuse were assessed by comparing 23 adolescent suicide victims and 12 community controls with a lifetime history of definite or probable DSM-III substance abuse. Suicide victims were more likely than controls to show the following risk factors: active substance abuse, comorbid major depression, suicidal ideation within the past week, family history of depression and substance abuse, legal problems and presence of a handgun in the home. Recommendations for the identification and prevention of suicide among substance-abusing youth on the basis of these findings are presented.

Objective: To assess the association between firearms in the home and adolescent suicide., Research Design: Matched, case-control., Setting: Population-based community sample., Subjects: Sixty-seven adolescent suicide victims and a demographically matched group of 67 living community controls., Selection Procedure: The series of adolescent suicide victims was consecutive, with an overall participation rate of 74% (67/91)., Measurements and Results: The presence, type (hand-gun vs long-gun), number, and method of storage (locked vs unlocked, loaded vs unloaded) of firearms in the home were compared between the suicide victims and controls. Even after adjusting for differences in rates of psychiatric disorders between suicide victims and controls, the association between suicide and both any gun (odds ratio [OR] = 4.4, 95% confidence interval [CI] = 1.1 to 17.5) and handguns (OR = 9.4, 95% CI = 1.7 to 53.9) in the home were both highly significant. Long-guns in the home were associated with suicide only in rural areas, whereas handguns were more closely associated with suicide in urban areas. Handguns (OR = 12.9, 95% CI = 1.5 to 110.9) and loaded guns (OR = 32.3, 95% CI = 2.5 to 413.4) in the home were particularly significant risk factors for suicide in those with no apparent psychiatric disorder., Conclusions: When pediatricians are faced with a suicidal adolescent, they should insist on the removal of firearms from the home. Pediatricians should also inform parents that the presence of firearms may be associated with adolescent suicide even in the absence of clear psychiatric illness.

The relationship between stressful life events and adolescent suicide was assessed in 67 adolescent suicide victims and 67 matched community controls. In the year before death, suicide completers were more likely to have experienced: (1) interpersonal conflict with parents and with boy/girlfriends, (2) disruption of a romantic attachment, (3) legal or disciplinary problems. Legal or disciplinary problems were more commonly associated with suicide in conduct and substance abuse disordered youth. Interpersonal loss was more commonly associated with suicide in substance abuse as well. Even after controlling for psychopathology, legal and disciplinary problems in the past year were associated with an increased risk of suicide.

Objective: To delineate the characteristics of adolescent suicide victims with no apparent psychiatric disorder., Method: Seven adolescent suicide victims with no apparent disorder were compared with 60 suicide victims with definite or probable psychiatric disorder, and with 38 community controls with no psychiatric disorder., Results: Suicide victims without psychiatric disorder, compared with the remainder of suicides showed lower rates of past psychiatric treatment, previous suicide attempt, family history of affective illness, total life stressors over the previous 12 months, and a greater prevalence of the availability of a loaded gun in the home. The seven suicide victims compared with the 38 psychiatrically normal community controls, showed a higher rate of familial psychiatric disorder, past suicidal ideation or behavior, legal or disciplinary problems in the past year, and firearms in the home, particularly those that were loaded., Conclusion: Even suicide victims without apparent psychiatric disorder still show some evidence of psychiatric risk factors compared with community controls. However, prevention of suicide in this group is probably best achieved by restriction of the availability of firearms, particularly loaded ones. The clinician should pay particular attention to suicidal risk in youth who are confronting legal or serious disciplinary crises and should take suicidal ideation seriously even in the absence of clear psychopathology.
