Decreasing disruptive behavior by adolescent boys in residential care by increasing their positive to negative interactional ratios.

An intervention for disruptive boys in residential care involving increases in positive to negative interactional ratios is described. The target of the intervention was daily problem behavior. Results from a pooled time series analysis of the data revealed a significant decrease in behavior problems (one problem per boy per day) during the intervention for the boys as a group. Results from comparisons of mean behavior problems during baseline and intervention revealed decreases for five of the six boys. Results from a multiple baseline across boys revealed experimental control for three of the six. The results are discussed in terms of response contingent reinforcement and systemic behavior analyses. The benefits of combined group and single subject data analyses are also discussed.

A longitudinal evaluation of prevalent negative beliefs about residential placement for troubled adolescents.

To investigate the validity of five prevalent negative beliefs about residential placement, we followed adolescents from a residential program and a comparison group at 3-month intervals for 4 to 8 years. This residential program in the Midwest uses the Teaching-Family Model in which six to eight adolescents live in a family-style environment. The interviews included five scales reflecting youths' views about important aspects of their lives in placement: (1) Delivery of Helpful Treatment, (2) Satisfaction with Supervising Adults, (3) Isolation from Family, (4) Isolation from Friends, and (5) Sense of Personal Control. Hierarchical linear modeling allowed us to estimate group differences while controlling for developmental trends, demographic factors, and prior differences between groups. The two groups were equivalent on all scales before the study. During the following placement, however, the treatment group's ratings were significantly more positive than the comparison group on four of the five scales and approached significance on the fifth. These findings suggest that negative beliefs about life in residential placement for adolescents may not apply to all programs.

Exploring the relationship between thumb-sucking and psychopathology.

Studied the relationship between chronic thumb-sucking and behavior problems reflective of psychopathology. Compared scores on the Child Behavior Checklist (CBCL) and Eyberg Child Behavior Inventory (ECBI) for matched samples of thumb-sucking, referred, and nonreferred children. Mean scores for the thumb-sucking and nonreferred samples were equivalent and were significantly lower than scores for the referred sample. Comparing scores for older children (8-14 years) and younger children (4-7 years) did not produce a significant interaction. Correlating measures of thumb-sucking severity with ECBI and CBCL scores produced only 8 (of 42) significant correlations and a mean correlation of only .09. Collectively our results provide little support for the theoretically derived notion that thumb-sucking is necessarily a symptom of psychopathology.
