An interventional study of Teen Council in Adolescent Problem Behavior, sponsored by Philliber Research & Evaluation. Completed. Open to participants aged 14 Years to 18 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2021-10-21.
Sponsored by Philliber Research & Evaluation · Not applicable, Interventional, and Prevention
This is a randomized controlled trial (RCT) evaluation of the Teen Council program that was tested with high school students (grades 10-12) to assess whether it results in a reduction of teen pregnancy among other outcomes.
Over the course of five years, we expected to have approximately 800 teens (400 program and 400 control) in the study. Teens were randomly selected for the program (Teen Council) and control (no program) conditions.
Teens in both groups were surveyed in the late summer/early fall of their enrollment year and each spring thereafter. Participation in the evaluation by control teens and unenrolled program teens was recognized with a small stipend.
The pre-survey was administered during the summer retreat for incoming Teen Council members. The same survey was administered by Philliber staff for the control youth via online, telephone, or mailed surveys during the late summer/fall. The post-surveys were administered at the end of the school year. Again, the survey was administered by program facilitators for the Teen Council program group. Philliber administered the post survey for the control group providing the same options for completion (online, telephone, or mail).
To facilitate follow-up, complete contact information was collected at baseline. This included the telephone numbers, physical addresses, and email addresses of the student and telephone numbers of their parents/guardians. Also requested was contact information for two relatives or adult friends who would likely know how to contact the teen. Parents were asked on the consent form to provide permission to receive change of school information in the event that their teen transferred to a new school. Philliber reached out to unenrolled Teen Council members and control group teens by telephone, email, text messaging, and/or U.S. Mail for survey administration (via telephone, online, or hard copy).

Exclusion Criteria:
Any interested participant who did not meet all of the inclusion criteria:
Teens assigned to the intervention group received a 1-year long Teen Council Program.
Behavioral: Teen Council
Teens assigned to the control group did not receive any intervention.
Youth randomly selected for Teen Council attended weekly meetings for an entire school year to receive training on specific topics. In turn, they provided educational presentations to the community, which required that they miss school (about one day per month). The presentations Teen Council members offered in middle and high schools were most commonly on birth control methods; relationships; reproductive anatomy and physiology; sexual diversity; STDs/STIs; sexual consent; HIV/AIDS; and abstinence.

Study participants were asked, "During the last year, have you made any changes in the use of protection from sexually-transmitted infections (STIs) or pregnancy? Item response categories included: I have never had sexual intercourse; I haven't had sexual intercourse in the past 12 months; no; yes.

Civic action scale
Six-item scale adapted from Flanagan et al. to measure ability to be actively engaged citizens (alpha = 0.6789). The scale, rated on a scale of 1 to 4, measured such things as the strength of their belief that they can make a difference in their communities and confidence that they can express their views in front of a group.

Perspective taking scale
Seven-item sub-scale from the Interpersonal Reactivity Index measuring the ability of youth to be empathetic and understand the perspective of others (alpha = 0.7158). This 5-point subscale included items to measure attempts to understand their friends by imagining how things look from their perspective and trying to look at both sides of every question. The scale language was adapted to be more gender neutral, with permission of the author.

Communication with parents
Two items about teen comfort talking with parents about sex and birth control, rated 1 to 4, with 4 indicating the highest level of comfort. These two items were examined individually. A third item measured whether youth had conversations with parents about sexuality or birth control in the past year (yes/no). A final item had teens report the number of such conversations in five unequal categories (0,1-5, 6-10, 11-15, and more than 15), then dichotomized to 10 or fewer conversations (0) and more than ten conversations (1).
