Study start date: March 1, 2003Actual date on which the first participant was enrolled.

The transition from middle school to high school presents important challenges for adolescents. Programs that enhance personal efficacy and social support resources may prevent at-risk students from developing behaviors that can lead to substance use, academic failure, and depression. This study will implement a skills-based program called Coping and Support Training for the Transition (CAST-T) as a preventive intervention for at-risk students. At-risk students in eighth grade will be randomly assigned to receive either CAST-T or school as usual. The CAST-T program will initially be delivered in twelve sessions over 6 weeks in the middle school setting. The program includes booster sessions, case management, structured home-based parent education, and support and skills training throughout the transition period. Participants will be assessed from the beginning of eighth grade to the end of ninth grade. Vulnerability to academic problems and depression will be assessed with school records and self-report scale scores.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
497 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Prevention Study
Prevention studies aim to stop a disease from developing. They often involve people at risk and test things like vaccines, lifestyle changes, or preventive medications.

How participants are assigned to different groups/arms
In this clinical study, participants are placed into groups randomly, like flipping a coin. This ensures that the study is fair and unbiased, making the results more reliable. By assigning participants by chance, researchers can better compare treatments without external influences.

Other Ways to Assign Participants
Non-randomized allocation: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.
None (Single-arm trial): If the study has only one group, all participants receive the same treatment, and no allocation is needed.

How treatments are given to participants
Participants are divided into different groups, each receiving a specific treatment at the same time. This helps researchers compare how well different treatments work against each other.

Other Ways to Assign Treatments
Single-group assignment: Everyone gets the same treatment.
Cross-over assignment: Participants switch between treatments during the study.
Factorial assignment: Participants receive different combinations of treatments.
Sequential assignment: Participants receive treatments one after another in a specific order, possibly based on individual responses.
Other assignment: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Double-blind: Neither participants nor researchers know which treatment is given.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Study Objectives
2 intervention groups 

are designated in this study

This study does not include a placebo group 

Treatment Groups
Group I
Experimental
The CAST-T/HSTS condition combined the Brief Intervention and 12 school based small group sessions which taught skills to enhance personal control (to manage depression, anger, stress), self-esteem, decision making and interpersonal communications. HSTS skills groups were held in the spring of 8th grade with 4 one-on-one booster sessions delivered to the students as 9th graders by HSTP leaders; parents also participated in 4 sessions. HSTS objectives are: 1) to increase the acquisition of coping skills competencies by teaching and practicing strategies taught; 2) to increase social support resources by building a supportive network; 3) to increase the youth's engagement in positive social activities; and 4) to motivate parents to increase their support via parent educational sessions.

Skills training small group.
Group II
Active Comparator
Brief Intervention: After each youth and parent completed baseline questionnaires the youth participated in a 1 on 1 standardized clinical follow-up with a trained clinician (blind to study condition) to review areas of concern, based on questionnaire responses including stressors at school, home, and with peers, level of support available and how to access support. The teen and clinician then planned a feedback call to parents, allowing teens to shape requests for support from parents as well as understand exactly what information would be shared with parents. Feedback call to parents reviewed concerns and made recommendations for services as needed. A similar procedure was followed after each assessment for all participants who indicated a risk of clinical depression or self-harm.

Assessment of needs and referral to services as needed.
Study Objectives
Primary Objectives

The Short Moods and Feelings Questionnaire is a 13 item measure of level of self reported depressive symptoms. Each item in scored on a 3-point Likert scale as follows: "True" (0), "Sometimes" (1), and "Not True" (2) rated within the timeframe of the previous two weeks. A total score is obtained; scores can range from 0 to 26. Total scores of 12 or higher may signify that a child/adolescent is suffering from depression. Higher scores on this scale suggest a worse outcome or greater endorsement of depressive symptoms. Change is measured based on two time points baseline to the 18 months follow-up assessment.
Secondary Objectives

School attachment measure consisted of 4 items. Item responses range from 0 (unsatisfied, rarely attended, not involved, etc.) to 6 (highly satisfied, regularly attended, very involved, etc). Scores could range from 0 to 36 with higher scores indicating more positive school attachment. Item were: My overall satisfaction with classes was... Overall, how safe did school feel last semester... Overall, how friendly did school feel... How involved were you in school activities...
