Trial Title: Advocating for Supports to Improve Service Transitions

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: SINGLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion criteria include:~1. parents willing to participate in the ASSIST 12-week intervention, who have an offspring with autism between the ages of 16 and 26 years. This age range was chosen to allow for the testing of whether the ASSIST is more effective if offered prior to versus after high school exit (a key moderator in Aim 4). The investigators set a lower bound of age 16, as that is when transition planning is mandated to have begun in the schools, and an upper bound of age 26 to capture families of youth who are still in the transition years as defined by the Institute of Medicine. If both parents in a family want to attend the training, the investigators will allow it but will designate one as the study's primary respondent. There is no minimum or maximum age limit for parent participants.~2. parents are willing to be randomized to the treatment or control condition;~3. parents are able to travel weekly to one of the project sites (Nashville, TN; Chicagoland;IL; Madison/Milwaukee, WI) to participate in the group ASSIST sessions (12 weekly sessions). The responding parent and the offspring with ASD must also be able to travel to a project site for a diagnostic evaluation to confirm the ASD diagnosis (using the gold- standard Autism Diagnostic Observation Schedule-2 or ADOS-2) and to establish IQ and adaptive behavior functioning;~4. the participating parent and youth must live in one of the states where the intervention is being delivered, as the adult service system is different in every state;~5. son/daughter has a previous diagnosis of ASD from an educational or health care provider, and meets lifetime cut-offs for ASD in a telephone screening of the Social Communication Questionnaire. This will decrease the risk that youth fail to meet diagnostic criteria for ASD during the diagnostic evaluation. Note that although the investigators will collect IQ and adaptive behavior information to assess functioning of the offspring with ASD, this information will not be used to determine eligibility; parents of offspring with all levels of functioning can participate in the ASSIST project; and~6. the participating parent is proficient with the English language, as all ASSIST presentations and data collection materials are in English.~Exclusion criteria include:~1. parents unable to participate in the ASSIST 12-week intervention due to scheduling conflicts, or who are unable to travel weekly to one of the sites;~2. parents NOT willing to be randomized to the treatment or control condition;~3. parents and/or youth do NOT live in one of the states where the intervention is being delivered;~4. The youth does not have a previous diagnosis of ASD from an educational or health care provider~5. The youth does not meet lifetime cut-offs for ASD in a telephone screening of the Social Communication Questionnaire, answered by the parent.~6. The participating parent is not proficient with the English language.

- Gender: ALL
- Minimum Age: None
- Maximum Age: None
- Healthy Volunteers: t

Study Arms:
- ASSIST intervention group (Type: EXPERIMENTAL): This group will attend the 12 sessions of the ASSIST training program (one 2-hour session per week for 12 weeks).
- Control: Written materials only group (Type: OTHER): This informational control group will receive the ASSIST binder and all written materials developed for the program on the same schedule as the treatment group but will not attend the group sessions.~After the treatment group is treated and follow up data is collected for comparison between treatment and control, the control group will have the option to take the ASSIST training program.

Based on this trial design, predict the completion outcome and termination type (if applicable).
