The relative costs and benefits of telephone interviews versus self-administered diaries for daily data collection.

This article compares two methods of collecting daily data: self-administered diaries and telephone interviews. Study participants included 44 men and 56 women between the ages of 16 and 35 who participated in a larger study of drinking, drug use, and sexual activity. Participants were randomly assigned to either the written diary or the telephone interview conditions; question wording and format were identical in both conditions. Daily data were collected for a period of 8 weeks. Results indicate that although telephone interviews resulted in slightly more missed days of data collection, they generally yielded less item-level missing data, produced cleaner data and therefore were less costly to process, and were as palatable to participants as self-administered diaries. Except for reports of drinking and vegetable consumption, telephone and diary conditions did not differ in the amount of behavior reported; more drinking and vegetable consumption were reported with telephone interviews, however. Telephone interviews also imposed considerably higher overall personnel costs.

Children's beliefs about drinking.

This paper reports the results of a study in which age (grade level), racial/ethnic, and gender differences in beliefs and perceived norms about drinking were examined in a multi-ethnic urban sample of 4th through 7th grade children. Results showed that older children held beliefs and perceived norms that were more favorable toward drinking than younger children. The major difference between older and younger children lay in their differential estimates of the likelihood of certain consequences occurring and not in their evaluation of these consequences of drinking. Further, older children not only displayed less motivation to comply with their parents and greater motivation to comply with their peers, but they also perceived their parents, as well as their peers, as less disapproving of drinking than did younger children. There were few gender or race/ethnicity differences at these ages in children's beliefs and perceived norms about drinking.

Reducing parental risk factors for children's substance misuse: preliminary outcomes with opiate-addicted parents.

Parents in methadone treatment were offered an experimental intervention, Focus on Families, designed to reduce their risk of relapse and their children's risk of substance use. Experimentally assigned volunteers participated in systematic group training in relapse prevention and parenting skills, and received home-based case management services. Immediate posttreatment outcome results reported here include analyses of covariance controlling for baseline measures. Analyses show experimental parents held more family meetings to discuss family fun, displayed stronger refusal/relapse coping skills, demonstrated stronger sense of self-efficacy in role-play situations, and had lower levels of opiate use than control subjects. No significant differences in family bonding, family conflict, or other measures of drug use were found. The utility of intervening with drug-addicted parents in methadone treatment is discussed in light of these findings.

Misconceptions about AIDS among children who can identify the major routes of HIV transmission.

Described knowledge about HIV transmission among 1,048 third, fourth, fifth, and sixth graders from a multiethnic urban school district. Participants answered questions about behaviors leading to HIV transmission and about mechanisms of transmission. Children at all grade levels demonstrated a high level of recognition of the three primary routes of HIV transmission (through sex, through drug needle sharing, and in utero). However, children who knew about these routes also had many misconceptions about the mechanisms involved in acquiring HIV through these routes and about the ways HIV is not transmitted. Misconceptions decreased with grade and socioeconomic status (SES). Although there were no race/ethnicity differences in knowledge of actual routes and mechanisms of HIV transmission, there were more misconceptions about routes and mechanisms of HIV transmission among African American and Asian American children than among white children.

Children's knowledge and beliefs about AIDS: qualitative data from focus group interviews.

Focus groups were used as a qualitative technique to elicit knowledge and attitudes of children in Grades 3 to 6 about acquired immune deficiency syndrome (AIDS). Twenty-seven small groups of children responded to open-ended questions about general AIDS knowledge; transmission, causation, consequences, and prevention of AIDS; emotional response to AIDS; and susceptibility. Results indicate that children have a high level of awareness about AIDS and correct knowledge about the modes of human immunodeficiency virus (HIV) transmission. They understand that AIDS is a serious illness that cannot be cured and know the main ways of preventing HIV infection. Participants had more difficulty explaining causation and greatly overestimated the number of people their age and in high school that might be infected. They also had difficulty applying accurate knowledge to the hypothetical situation of encountering a child with AIDS in school. Misconceptions about AIDS exist at all grade levels, but appear more prevalent in lower grades, whereas increased complexity seems to characterize responses of older children. Recommendations for health educators are made.

Participation in a parent training program for methadone clients.

Programs for drug abusers are plagued by high rates of dropout. Because of the strong relationship between longer treatment and positive outcome, researchers have begun to study individual and program-specific factors that influence premature termination of treatment. For the most part, these studies have focused on dichotomous measures of dropout or number of sessions attended. In this article, we extend this line of research in two ways. First, we develop and measure a number of indicators of treatment participation based on therapist ratings. Second, we develop a model of treatment participation that employs both individual and program-specific factors. The data show that tremendous variation in participation occurred even among those who attended a majority of sessions, which highlights the importance of obtaining more elaborate measures of treatment participation. The model predicting treatment participation suggests that initiation of heroin use later in life, continued use of marijuana, and behavioral indicators of motivation are the strongest predictors of program participation. Research and practical implications of the findings are discussed.
