Coping Power Program
Study: Zonnevylle-Bender et al. (2007); van de Wiel et al. (2007)

Summary

The Coping Power Program is a preventive intervention delivered to at-risk children in the late elementary school and early middle school years. Developed as a school-based program, Coping Power has also been adapted for delivery in mental health settings.Coping Power is based on an empirical model of risk factors for substance use and delinquency and addresses key factors including: social competence, self-regulation, and positive parental involvement. The program lasts 15 to 18 months in its full form. An abbreviated version encompassing one school year is also available.

Participants Full Bobble

Describe how students were selected to participate in the study:
Children entering four child psychiatric outpatient clinics and three mental health centers during a period of almost 3 years (October 1996-August 1999) were allowed to participate in the study when they met the inclusion criteria. Children were included if (a) they were 8 to 13 years of age, (b) they met the criteria for DBD in accordance with DSM-IV (American Psychiatric Association, 1994; comorbidity with other disorders was allowed), (c) they were living within a family (i.e., not in an institution), and (d) their intelligence was at least 80 based on the results of two subtests (Vocabulary and Block Design) of the Wechsler Intelligence Scale for Children–Revised (Vandersteene et al., 1986; Wechsler, 1974).

Describe how students were identified as being at risk for academic failure (AI) or as having emotional or behavioral difficulties (BI):
All child participants had a Disruptive Behavior Disorder diagnosis.

ACADEMIC INTERVENTION: What percentage of participants were at risk, as measured by one or more of the following criteria:
  • below the 30th percentile on local or national norm, or
  • identified disability related to the focus of the intervention?
%

BEHAVIORAL INTERVENTION: What percentage of participants were at risk, as measured by one or more of the following criteria:
  • emotional disability label,
  • placed in an alternative school/classroom,
  • non-responsive to Tiers 1 and 2, or
  • designation of severe problem behaviors on a validated scale or through observation?
%

Specify which condition is the submitted intervention:
UCPP. The UCPP is an adaptation of the CPP (Lochman & Wells, 1996), a school-based preventive intervention program that includes a parent and a child component. Because the CPP is a preventive program of intervention, the UCPP needed to be adjusted for the more severely disturbed children and their parents. For example, the UCPP sessions were more varied, with proportionally fewer discussions and more activities to suit the short attention span of the children. In addition, the CPP child component consists of 33 weekly sessions during a 15-month period. Such a period is very long for use in everyday clinical practice. We therefore reduced the number of sessions of the child component to 23 during a period of 9 months, whereas the number of sessions of the parent component was reduced from 18 to 15. The parental and the child components were not only combined, they were also integrated. This was accomplished in several ways. First, the same therapists were used for both the parental and the child groups. This made it easier to transfer the information on children’s achievements and progress to their parent or parents and reduced the risk that children would try to play the therapists and parents against each other. Second, to involve the parents in the child treatment, the last fourth of the parental meeting was devoted to the previous child session or sessions. Parents were given a summary of the child session or sessions, and the therapists explained the topics of the child session or sessions. In several parental sessions, some minutes of videotaped child sessions were also shown (e.g., anger management, each of the five problem-solving skills).

Specify which condition is the control condition:
Control condition. Participants were provided with mental health services typically offered in each of the facilities. The decision about the type of treatment for each participant was made in staff meetings and was based both on clinical and pragmatic grounds (e.g., availability of therapists). The treatments in the C condition were divided into three groups: (a) family therapy (n=10), (b) behavior therapy (n=16), and (c) various other treatments (e.g., parental guidance, play therapy; n=13). To divide the treatments into one of the three groups, charts were reviewed to identify the type of treatment, and type was checked with the therapist. Then, the types of treatment were categorized into one of the three groups. Family therapy was based on general systems theory (Watzlawick, Bavelas, & Jackson, 1967) and communication theory (Jackson, 1967). Family therapy was not manualized. Family therapists were specifically trained (through courses and supervision by qualified supervisors across multiple years). Their mean years of experience with family therapy was 3.22 (SD=7.01), and their mean years of experience of being a therapist in general was 10 (SD=6.93). The number of the family therapy sessions was 11.20 (SD =6.29). Behavior therapy consisted of either manualized group social skills training for the child combined with manualized group sessions with the parents or nonmanualized individual treatment with the child and the parents. In both forms of behavior therapy, operant and cognitive procedures were combined. The behavior therapists were specifically trained (through courses and supervision by qualified supervisors across multiple years). Their mean years of experience with behavior therapy was 6.05 (SD=5.95), and their mean years of experience of being a therapist in general was 10.6 (SD=7.57). The number of the behavior therapy sessions was 17.75 (SD=13.93). Other treatments varied to such an extent that they were not included in the analyses.

Describe when and how fidelity of treatment information was obtained.
To ensure that these intervention components were provided as planned, procedures were formulated for developing and evaluating intervention integrity. Detailed manuals were used for both the UCPP parent component and the UCPP child component. Moreover, all child and parent group sessions were videotaped for random selection by the supervisors (i.e., experienced clinicians) to check adherence to protocol.

What were the results on the fidelity-of-treatment implementation measure?

Measures and Results

Measures Targeted : Full Bobble
Measures Broader : Dash

Study measures are classified as targeted, broader, or administrative data according to the following definitions:

  • Targeted measures
    Assess outcomes, such as competencies or skills that the program was directly targeted to improve.
    • In the academic domain, targeted measures typically are not the very items taught but rather novel items structured similarly to the content addressed in the program. For example, if a program taught word-attack skills, a targeted measure would be decoding of pseudo words. If a program taught comprehension of cause-effect passages, a targeted measure would be answering questions about cause-effect passages structured similarly to those used during intervention, but not including the very passages used for intervention.
    • In the behavioral domain, targeted measures evaluate aspects of external or internal behavior the program was directly targeted to improve and are operationally defined.
  • Broader measures
    Assess outcomes that are related to the competencies or skills targeted by the program but not directly taught in the program.
    • In the academic domain, if a program taught word-level reading skill, a broader measure would be answering questions about passages the student reads. If a program taught calculation skill, a broader measure would be solving word problems that require the same kinds of calculation skill taught in the program.
    • In the behavioral domain, if a program taught a specific skill like on-task behavior in one classroom, a broader measure would be academic performance in that setting or on-task behavior in another setting.
  • Administrative data measures apply only to behavioral intervention tools and are measures such as office discipline referrals (ODRs) and graduation rates which do not have psychometric properties as do other, more traditional targeted or broader measures.

If you have excluded a variable or data that are reported in the study being submitted, explain the rationale for exclusion:
Describe the analyses used to determine whether the intervention produced changes in student outcomes:
To study the effect of treatment, we used repeated measures analyses of variance (ANOVA) with treatment condition as the between-subjects factor and time as the within-subjects factor. First, we compared UCPP (n =38) to C (n =26), consisting of participants in the family therapy and behavior therapy groups. Second, we compared UCPP to family therapy (n =10) and UCPP to behavior therapy (n =16). Because of the low numbers of participants in the family therapy and behavior therapy groups, we also tested treatment effectiveness in terms of effect sizes. The effect size statistic is an index of the magnitude and direction of therapy effects. Effect size is the difference between the means of two sets of scores divided by the pooled standard deviation of the two sets (Cohen, 1988). The two set of scores consisted of difference sores, that is, the difference between pretreatment and posttreatment scores within each condition. The index d is a measure of the degree to which the two sets differ in terms of standard deviation units. For example, a d index of .25 indicates that the two means were separated by one fourth of a standard deviation. In general, an effect size of .80 is considered to be large, .50 moderate, and .20 small (Cohen, 1992).
