Involving caregivers in their children's services often is assumed to make the delivery of child-focused services more effective. We examined the relation of caregiver involvement in children's early intervention programs (EIPs) with caregiver-child interaction. Participants were 99 low-income single caregivers whose children ( 40 months old) were enrolled in EIPs that provided opportunities for caregiver involvement. The results confirmed that caregivers who were more engaged with the programs (as rated by program staff) were more likely to demonstrate more responsiveness in interactions with their children. However, the frequency of participation or number of different types of activities at the EIPs in which they engaged were not significantly related to caregiver-child interaction. Implications are discussed for enhancing supportive and collaborative relationships between caregivers and providers.

Family functioning was investigated as a mediator between interparental conflict and adolescent depressed mood among adolescents living in two-parent and divorced families. Data were collected three times, with one year intervals. At the initial interview, adolescents were, on the average, 15.5 years old. Two types of interparental conflict were assessed: interparental conflict involving arguments about the adolescent, and arguments focused on the parents' behaviors. The results confirmed that family functioning mediated the effects of parent issue/interparental conflict, but not adolescent issue/interparental conflict. This was most evident for girls than boys. Implications of the findings for research and practice are discussed.

The question of how cocaine overdoses are related to preferred routes of cocaine administration and other aspects of cocaine use patterns is sufficiently complex that very little information is available on it. Even the most extensive information on cocaine overdoses, that of the Drug Abuse Warning Network, is severely limited for purposes of examining this topic. Findings are presented from a 1988-1990 study of a purposive but demographically diverse sample of 699 crack and other cocaine users in Miami, 349 of them interviewed in residential treatment and 350 interviewed on the street. Among these respondents: a history of cocaine overdose is extremely common; overdose episodes do not commonly motivate treatment entry and in some populations are relatively unlikely to result in an emergency room visit; cocaine overdose is less associated with crack smoking than with snorting or intravenous (IV) use, whereas IV use is especially likely to result in overdose; and the street and treatment samples are strikingly different in regard to drug use patterns, overdose history, changes some users made to use patterns as a result of overdose experiences, and reasons given by other users for not making such changes.

By focusing on the roles of family characteristics, stress, and a program's organizational climate, this study investigated why some low-income single caregivers with children with disabilities tend to be more involved in early intervention services than others. The participants in this research were low-income single caregivers whose young children were enrolled for the first time in early intervention programs with opportunities for caregiver involvement. The results indicated direct effects for family characteristics in predicting caregiver/program involvement. Relationships between family characteristics and caregiver/program involvement were also moderated by parenting stress and perceptions of a supportive program climate. Implications for family-centered practice are discussed.

Studies of treatment samples have long been the primary source of generalizations about drug users, especially for drugs with very low prevalence rates in the general population, such as heroin and crack. Sample selection bias is briefly discussed, and a 1988-1990 study of 699 cocaine users in Miami is described. The drug patterns of the 387 adult crack users interviewed in that study are compared by sample type--residential treatment versus street, controlling for gender. Some similarities between sample types were found, but differences were more numerous. Notably, street respondents started cocaine at a younger age; had used crack regularly for a longer period of time; were more likely to have used pills, heroin, and freebase cocaine; were much more likely to be using crack (but only crack) on a daily basis; and were more likely to obtain crack by being paid in it, especially for drug dealing. Treatment respondents were more likely to use multiple forms of cocaine, to use cocaine in a binge pattern and with high per-day dosages, and to pay for cocaine with cash they got from a job.
