This longitudinal study examined the relation between the instability of maternal intimate relationships and the school behavior of 3rd-grade children from economically disadvantaged families. After ecological correlates were controlled, chronic relationship instability predicted externalizing behavior for boys and girls and internalizing behavior for girls, but not academic competence. In addition, past and recent instability had independent effects: Recent instability moderated the relation for past instability, and child adjustment in highly unstable families varied with verbal ability and aspects of the family ecology. The theoretical implications concern conceptualizations of the diverse and dynamic nature of family arrangements experienced by disadvantaged children.

This study examined the relations among family structure, caregiver relationship history, aspects of environmental adversity, and teacher reports about the externalizing behaviors of 6- and 7-year-old children from economically disadvantaged families. Family structure contrasted intact families, stepfamilies, single-parent families, and cohabiting families. Problem behaviors were more frequent for children from unmarried families than from married families and were more frequent for boys than for girls from cohabiting families. Relationship history reduced the effects for family structure. Children's adjustment varied with both the current status and past stability of caregiver intimate relationships for disadvantaged families.

This study examined relations between suicidal behavior history (i.e., no suicidality, suicidal ideation, single attempters, and multiple attempters) and psychiatric functioning. Adolescents, aged 12-17, admitted to an inpatient psychiatric unit, were categorized by suicidal behavior history based on self- and clinician-report data. Groups were examined for differences in suicidal ideation and psychiatric diagnosis. Severity of suicidal ideation increased with severity of suicidal behavior history. Females were disproportionately represented among multiple attempters. Multiple attempters were more likely to be diagnosed with at least one externalizing disorder, particularly substance use disorders, and to have more than one comorbid diagnosis than adolescents with no suicidal behavior or a history of ideation only. Clinicians should be alerted to the particularly high-risk nature of adolescents with multiple suicide attempts.
