Psychotropic medications are the first-line treatment across several diagnostic categories encompassing severe mood disturbances and behavioral problems. The use of Second Generation Antipsychotics (SGAs) has increased in children with Autism Spectrum Disorder (ASD) in the last decade. However, SGAs are associated with serious metabolic side effects in youth that include cardiovascular disease, hypertension, and diabetes mellitus. This makes the public health impact of treating medication-induced metabolic disturbances almost as important as treating the mental illness itself. Improving health and reducing premature mortality in people with severe mental illness, the investigators propose to provide early weight management prevention, delivered by clinicians, for youth starting SGAs in order to target common modifiable health risk factors in the developmental process. This study will provide an urgently needed practical model for integrating weight management into academic- and community-based autism care.
The innovations are four-fold: (1) adapting an evidence-based weight management treatment for youth/adolescents and young adults with Autism Spectrum Disorder (ASD); (2) training providers embedded within standard psychiatric care setting in an empirically-validated intervention for weight management; (3) utilizing a collaborative care model for weight management in psychiatric care for youth starting second generation antipsychotics (SGAs) to prevent/decelerate metabolic dysfunction; and (4) identifying factors that affect implementation into all Autism Treatment Network (ATN) sites. Given recent calls to move toward community-based obesity prevention approaches among high-risk youth, this study will provide an urgently needed intervention for adolescents and young adults with ASD on medications known to have untoward metabolic adverse effects. Moreover, this study will serve as a pilot mechanism to expand upon the findings in multiple ATN sites in a large-scale randomized control trial while measuring cardiometabolic outcomes. This pilot investigation has the potential to change standard of care within clinical practice that can be widely disseminated. Aim 1: To refine the HH4L manual to meet the needs of youth/adolescents and young adults (IQ \> 70) with ASD on SGAs by adding Cognitive Behavioral Therapy (CBT) techniques for managing behaviors related to eating and physical activity to an empirically-validated pediatric obesity manual and incorporating developmentally appropriate modifications for individuals with ASD with an emphasis on family-based changes. Hypothesis 1.1: The CBT intervention will be feasible to deliver to adolescents and young adults with ASD and their family members. Hypothesis 1.2: Participants will attend treatment regularly with low attrition (≤ 20%) and high attendance (\>80%). Aim 2: To test the efficacy of a psychiatrically-embedded weight management program for youth with ASD on SGAs. At the end of the 6-month program, youth receiving the weight management program (HH4L) will show improvements in: Hypothesis 2.1: Maintained or decreased weight on BMI z-score (Primary Outcome) Hypothesis 2.2: Ameliorated insulin resistance assessed by homeostatic model of assessment (HOMA-IR)(Secondary Outcome) Hypothesis 2.3: Decreased systemic inflammation evaluated by circulating high sensitivity C-reactive protein (hs-CRP) Exploratory Aim 3: To obtain a better understanding of how to support the effective implementation of HH4L into ATN sites. Hypothesis 3.1. Identify organizational, clinician, and patient factors associated with effective implementation. The main aim of this study is to adapt the Healthy Habits for Life manual to meet the needs of high-functioning adolescents and young adults with ASD who gain \>7% of initial body weight while taking a SGA (or \>5% if overweight/obese). HH4L is a CBT, MI, and family-based weight management intervention. However, proposed changes may include emphasizing the effects of SGAs on appetite, adapting cognitive foci to behavioral, emphasizing the role of family in stimulus control, and focusing on sneak eating. HH4L-ASD will involve eleven 45-minutes sessions over a 6-month period. Dependent measures will include physiological outcomes (e.g., Body Mass Index; BMI) and emotional/behavioral outcomes (e.g., Aberrant Behavior Checklist) collected at baseline and monthly there-after. While outcome data will inform next steps, the main aim of this pilot is to create a manual that can be implemented at all ATN sites. Study Flow: Families will be informed of the study by staff at the Pitt ATN. Interested families will undergo either a telephone or face-to-face screen, at which time they will be provided with additional information regarding study aims and expectations. At a subsequent in-person screen/baseline assessment, the child/family will have all questions answered and will sign an informed assent and consent. All participants will receive treatment. There are 4 weekly sessions, 4 bi-weekly sessions, and 3 monthly booster sessions over a 6 month period. Given that some families come from far away and there are often barriers that impact patient attendance, 25% of all sessions will be permitted to be via phone or text sessions. These are options in line with prior investigations by PI Rofey. These telehealth standards are similar to the research group's prior work validating the effectiveness of HH4L. Participants will work one-on-one with a practitioner who has been delivering HH4L for over a decade. Retention rates are expected to be commensurate with similar studies (\~ 90%). Data Management. The Principal investigators (PIs) will oversee all aspects of data management. With the consultation of the Massachusetts General Hospital Data Coordinating Center (DCC), the PIs and coordinator will develop an operations manual to standardize all procedures and staff training. All study participants will be assigned unique study identifiers that will appear on all data collection instruments, tapes, documents, and files used in the statistical analysis and manuscript preparation. The DCC also has specific data quality measures that will be implemented. Statistical Analyses Data will be summarized using sample means or proportions along with 95% confidence intervals within each study arm. Attrition and Missing Data. Every effort will be made to minimize the amount of attrition and missing data. The current research group has a history of successful retention of subjects in clinical research protocols. Participants are able to conveniently schedule research visits to correspond with regularly scheduled clinical appointments. Retention rates in 2 similar random control trials range from 80-90%. Follow-up assessments will be attempted even if a participant has dropped out of the training program. The investigators will also offer shortened assessments to convert initial refusals. Sample size. The sample size (25 participants) is based on feasibility considerations for the recruitment period. With 25 participants enrolled, the exact 95% confidence interval on a completion rate of 80% is 59.30%-93.17%. Assuming 80% have a 6-month BMI measurement, and 80% are lower than at baseline, the exact 95% confidence

Change in emotional dysregulation
Change in emotional dysregulation as measured by the Emotion Dysregulation Inventory with 30 items on two factors: (1) Reactivity, characterized by intense, rapidly escalating, sustained, and poorly modulated negative emotional reactions, and (2) Dysphoria, characterized by anhedonia, sadness, and nervousness. Items are rated on the following scale to reflect current behavior: and how much of a problem it has this been in the preceding 7 days?: Not at all (0, never happens) Mild (1, Present occasionally) and/or does not cause too much of a problem Moderate (2, Happens less than half the time and/or causes some problems Severe (3, Happens at least half of the time and/or substantially interferes Very Severe: 4, Almost always happens and/or causes a serious problems Scores for items on each factor are summed for a total scale score. Higher scores suggest more emotional dysregulation on that specific factor.

Change in weight loss behaviors
Change in weight loss behaviors as measured by the Weight Loss Behavior Stage of Change Scale (WLB\_SOC). The numerical values on the WLB-SOC questionnaire directly correspond to the five Stages of Change:1 = pre-contemplation; 2 = contemplation; 3 = preparation; 4 = action; 5 = maintenance The questionnaire has 5 sections: Potions, Dietary Fat, Fruits, Vegetables, Usual Physical Activity. For sections that have 9 or 10 questions (i.e., Portions, Fruits and Vegetables, Usual Physical Activity), the SOC is determined by using the third lowest stage for the behavioral items. For sections that have 11 questions (Dietary Fat), the SOC is determined by using the fourth lowest stage indicated for the behavioral items. Items answered "N/A" or left blank are scored as a "1".
Time frame: change from Baseline to intervention completion at 6 months
Change in physical activity habits
Change in physical activity habits as measured by the Modifiable Activity Questionnaire (MAQ). This measure is a self-reported questionnaire that records frequency and duration of different levels of physical activity. The MAQ assesses current physical activity during both work and leisure time, as well as some inactivity. The hours per week of all activities are summed to determine total hours per week.
