简要总结
Family-based treatments (FBT) for obesity have been shown to be effective in achieving significant weight reductionin overweight or obese children and parents [Altman & Wilfley, 2015]. One component of the current FBT programused in this study that has received little attention is thought training, specifically episodic future thinking (EFT). EFTteaches individuals to pre-experience events, or think prospectively, about future events as if they were happeningnow and has been shown to reduce delay discounting (DD) which is defined as discounting smaller rewards now for a larger reward in the [Daniel, Said, Stanton, & Epstein]. Furthermore, EFT has been shown to help people purchase fewer calories when they are grocery shopping [Hollis-Hansen et al., 2019], thereby displaying potential to be an effective measure in modulating the food environment in homes and may play a role in changing eating behaviors related to weight loss [Appelhaus et al.,2019].
Given the power of EFT in promoting the purchase of fewer calories, it is plausible that EFT training focused around grocery shopping during FBT could help shift one's thought processes towards healthier food choices, promoting behavioral change that has lasting impact on the home environment. Thus, the primary purpose of this study is to assess whether EFT training promotes active behavioral change pertaining to grocery shopping during FBT. In turn,this resulting behavior change could lead to healthier eating behavior and may promote weight loss for the whole family.
We hypothesize:
- There will be a reduction in BMI for adults/percent over BMI for children and weight from baseline
- There will be a reduction in delay discounting for children
详细描述
The study program is organized into 15 sessions. There is a mix of group sessions, individual family in-person sessions, and individual family phone sessions. Each session is outlined below:
WEEK 0 - Baseline Session: In-Lab Group Session - All Baseline sessions were completed as planned in lab.
First, upon arriving to the lab, each dyad will be escorted to a private room and will complete the following:
- Have height and weight measured.
- Complete surveys: Consideration of Future Consequences Scale (CFCS), EDE-Q (Parent), KEDS (Child)
- Complete the Delay Discounting Task, the Online Grocery Shopping Task, and Home Food Inventory. A letter was sent to each family explaining the change from in-home visits with the Cupboard inventory to the self-completed Home Food Inventory, due to growing concern over COVID-19.
- Receive first assessment payment ($40 dollars)
Following steps 1-4, the families will take part in a group session to learn the core components of the program in presentations by the research staff.

入选标准
- •Child age between 10-14
- •Child height and weight that calculates to a BMI above the 85th percentile (BMI in overweight/obesity range)
- •Parent height and weight that calculates to a BMI above 18
- •Possession of at least one electronic device (per family) with WiFi capabilities (e.g. smartphone, tablet, computer)
- •Home internet access
- •Motivation to lose weight
排除标准
- •Disordered eating patterns (e.g. binge-eating disorder, extreme weight-loss behaviors)
- •A family history of eating disorders (siblings, children, parents, or grandparents)
- •Medical conditions that are known to interfere with weight-loss (e.g. type 1 diabetes, thyroid disease)
- •Medical conditions that may affect their ability to use the computer for a prolonged period of time or follow study protocol
- •Psychopathology or disabilities that would limit adherence to protocol (e.g. depression, suicidality, ADHD). Participant will only be excluded if the disability would not allow them to adhere to protocol. Just having the disability does not exclude them. Suicidality would be automatically be exclusionary)
- •Substance use, abuse, or dependence (e.g. binge drinkers, illicit substance users, alcoholics)
- •Plans to start or stop a medication that may affect appetite/weight-loss during the intervention period
- •Have started a medication within 6 months that is affecting appetite/weight-loss
- •Plans to move out of the area during the treatment period
- •Pregnancy/breastfeeding or plans of becoming pregnant during the study period
- •Is participating in another weight-loss program
- •Can not successfully record eating behavior in the MyFitnessPal app
- •A) Had bariatric surgery less than one year ago B) If the potential participant had bariatric surgery over a year ago, their weight has not been stable for at least 6 months
研究组 & 干预措施
Episodic Future Thinking Group 7-week baseline
The experimental group will receive the Episodic Future Thinking (EFT) intervention after a 7-week baseline. EFT teaches individuals to pre-experience events, or think prospectively, about future events as if they were happening now [Atance].
干预措施: Episodic Future Thinking Group (Behavioral)
Episodic Future Thinking Group 10-week baseline
The experimental group will receive the Episodic Future Thinking (EFT) intervention after a 10-week baseline. EFT teaches individuals to pre-experience events, or think prospectively, about future events as if they were happening now [Atance].
干预措施: Episodic Future Thinking Group (Behavioral)
