The Effectiveness of Group Interpersonal Synchrony in Young Autistic Adults' Work Environment
Study Details
Study Description
Brief Summary
Background: Few autistic adults are able to integrate successfully into the world of work given their difficulties adapting to the social and stressful aspects of work environments. Interpersonal synchrony, when two or more individuals share body movements or sensations, is a powerful force that consolidates human groups while promoting the ability to self-regulate and cooperate with others. The abilities to self-regulate and cooperate are crucial for maintaining a calm and productive work environment.
Objectives: This randomized controlled trial (RCT) aims to assess the effects of group interpersonal synchrony on prosociality and work-related stress of young autistic adults in their work environment.
Methods: This mixed-methods RCT will investigate two movement-based group synchronous and non-synchronous intervention conditions. The sample will be composed of young adults enrolled in an innovative Israeli program designed to integrate cognitively-abled 18- to 25-year-old autistic adults into the Israeli army work force. The movement-based intervention sessions will take place in groups of 10-14 participants, once a week for 10 weeks. Questionnaires, behavioral collaborative tasks and semi-structured interviews will be conducted. Quantitative data will be collected for each participant at three points of time: before and after the intervention period, and four months after the end of the intervention. Qualitative data will be collected after the intervention period in interviews with 15% of the participants.

Detailed Description
Background: Few autistic adults are able to integrate successfully into the world of work given their difficulties adapting to the social and stressful aspects of work environments. Interpersonal synchrony, when two or more individuals share body movements or sensations, is a powerful force that consolidates human groups while promoting the ability to self-regulate and cooperate with others. The abilities to self-regulate and cooperate are crucial for maintaining a calm and productive work environment.
Objectives: The objectives are to determine:
-
whether a synchronized group intervention will have an immediate and/or long-term positive effect on participants' prosociality and work-related stress.
-
whether this effect will be mediated by participants' reported social closeness and sense of belonging.
-
whether this effect will be influenced by participants' need to belong as reported before the intervention.
-
how participants perceive the intervention as affecting their prosociality and work-related stress.
-
in what ways the participants' perception of the intervention as affecting their prosociality and work-related stress will contribute to a better understanding of the intervention effect.
Methods: A mixed methods approach will be applied, where quantitative and qualitative data are collected and analyzed in parallel.
Participants: The sample will be composed of young adults (n=60) enrolled in an innovative Israeli program designed to integrate cognitively-abled 18- to 25-year-old autistic adults into the Israeli army workforce.
Sample Size: An a-priori power analysis indicated that a total sample size of 42 participants would be needed to detect medium effects defined as f=0.2, with 80% power and alpha at .05, using a repeated measure, within-between interaction ANOVA. This sample size might not be sufficient for detecting the mediated effect needed to respond to the second study objective with 80% power and alpha of .05. Therefore, we will recruit at least N = 60 participants (30 in each intervention group) to plan for possible dropouts.
Study Design and Procedures: This is a two-arm, randomized controlled trial (RCT) in which participants will be randomly assigned to one of two groups: synchronous and non-synchronous movement-based interventions. The movement-based intervention sessions will take place in groups of 10-14 participants, once a week for 10 weeks. A structured physical training protocol will be used for each condition. Each protocol is composed of 10 physical training sessions, each lasting 60 minutes. The protocols differ in terms of using synchronous activity vs. non-synchronous activity. They do not differ in terms of physical exercise type or duration to control for the effect of exercise type and duration on the dependent variables. Questionnaires, behavioral collaborative tasks and semi-structured interviews will be conducted. Quantitative data will be collected for each participant at three points of time: before and after the intervention period, and four months after the end of the intervention. Qualitative data will be collected after the intervention period in interviews with 15% of the participants.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Synchronous condition This arm (n=30) will include a synchronous intervention only. |
Behavioral: Structured synchronous physical training
The instructors and the participants will form a circle facing each other while doing the physical exercises. To facilitate interpersonal synchrony, the participants will be instructed to do the same physical exercises (spatial synchrony) together at the same pace (rhythmic synchrony). Each session will consist of four parts:
Warm-up (10 minutes)
Social Game (10 minutes)
Main training (30 minutes): Each session will contain two sets, each consisting of seven fixed exercises with a resting period of 10-15 seconds between each. Each exercise will be performed at one of three different paces: Slow - one movement cycle per 2 seconds, Medium - one movement cycle per 1 second and Fast - two movement cycles per 1 second.
Cool-down (10 minutes)
|
| Active Comparator: Non-synchronous condition This arm (n=30) will include a non-synchronous intervention only. |
Behavioral: Structured non-synchronous physical training
The participants will do the same physical exercises as the participants in the synchronous group but in the form of circuit training with seven stations. The circuit training will require the participants to do a different physical exercise at a different pace at each station. A detailed description of the exercises will be provided for each station. The instructors will demonstrate all the exercises before the beginning of training. The participants will be instructed to do the exercise for a set period of time, the same duration used in the synchronous group. The circuit training stations will be in the form of a circle but will be set up so that the participants do not to face each other when doing the exercises to prevent spontaneous synchronization. Each session will consist of four parts, the same as in the synchronous intervention.

Outcome Measures
Primary Outcome Measures

Work-related stress will be measured using the Hebrew adaptation of the Irritation Scale. This scale comprises eight items, three of which assess cognitive irritation and five of which assess emotional irritation. Items are rated on a 7-point Likert scale ranging from "Strongly Disagree" (1) to "Strongly Agree" (7).
