Study Description

Brief Summary:

SENSE Theatre®, combines several well-documented, effective behavioral strategies, such as the inclusion of trained peer models, theatre play techniques involving predictable (i.e., scripted) and flexible (improvised) role-play, and repeated performance of newly learned skills resulting in greater automaticity of behavior. The intervention has the potential to enhance social cognition and behavior in adults with autism spectrum disorder.

Detailed Description:

Autism spectrum disorder (ASD) is characterized by primary impairment in social competence. Effects of current psychosocial interventions often fail to maintain or generalize and few employ rigorous experimental methods. Our treatment, SENSE Theatre®, combines several well-documented, effective behavioral strategies, such as the inclusion of trained peer models, theatre play techniques involving predictable (i.e., scripted) and flexible (improvised) role-play, and repeated performance of newly learned skills resulting in greater automaticity of behavior. Recent findings from a randomized control trial (RCT) show immediate between-group effects and evidence of target engagement on the hypothesized mechanism of action, memory for faces, which was evaluated by neuropsychological and event-related potential (ERP) measures. Moreover, the RCT demonstrated treatment effects on social communication skills that generalized to home and community settings. Finally, maintained treatment effects were observed on communication symptoms. The proposed project will extend these findings and provide a stronger test of efficacy using an RCT of SENSE Theatre with a sample of approximately 40 adult participants with ASD (18 to 35 years) randomized to experimental (EXP; N = 20) and a wait list control group (WLC; N = 20) in two separate cohorts. The RCT will assess target engagement of memory for faces and functional change in social interaction with peers using examiners blind to study treatment group assignment. The significance and size of treatment effects on these cognitive and behavioral outcomes will be measured using ANOVA and linear mixed models. Thus, the overarching aim of the study is to determine whether detected changes in face memory and social interaction are due to the SENSE Theatre® treatment and the extent to which these changes generalize and maintain. If predicted results occur, it will provide strong empirical support for a community-based treatment that has generalized effects on a set of core deficits that otherwise have life-long consequences for adults with ASD.

Arms and Interventions

Arm	Intervention/treatment
Experimental: SENSE Theatre; A peer-mediated, theatre-based intervention designed to improve social cognition and behavior.	Behavioral: SENSE Theatre; A peer-mediated, theatre-based intervention that involves 10 sessions of approximately 3 hours each that culminates in a public performance.
No Intervention: Waitlist Control Group; This group will not receive the intervention during the testing phase of the intervention but will eventually receive the theatre intervention.

Outcome Measures

Primary Outcome Measures :

1. Change in Incidental Face Memory [ Time Frame: Pretest to Week 11 ]
   An event-related Potential Task that presents 51 novel faces and 51 novel houses one of each is randomly selected and presented 50 times (repeated). We are examining an increase in amplitude of 250-500 ms time window between the repeated and single face presentation. Positive values indicate better face memory.
2. Change in Contextual Assessment of Social Skills [ Time Frame: Pretest to Week 11 ]
   An observational assessment measure of social cognition and communication which includes two 3-minutes conversations with typically developing peers showing interested or bored demeanor. The behaviors are rated based on raw scores on a likert scale from 1 to 7 with 7 reflecting better ability.
3. Change in Social Responsiveness Scale - Self (SRS) [ Time Frame: Pretest to Week 11 ]
   The SRS is a standardized measure of social competence administered by participants pertaining to behaviors characteristic of adults with ASD. T-scores range from scores of 38 to 90 with higher scores reflecting greater impairment.
4. Change in Social Responsiveness Scale - Parent (SRS) [ Time Frame: Pretest to Week 11 ]
   The SRS is a standardized measure of social competence administered by care-givers pertaining to behaviors characteristic of adults with ASD. T-scores range from scores of 38 to 90 with higher scores reflecting greater impairment.

Secondary Outcome Measures :

1. Cambridge Face Memory Test [ Time Frame: Pretest, Week 11, two-month follow-up ]
   A standardized measure of face memory with 72 items. Any increase in the raw score pertaining to the number of faces identified constitutes an increase in face memory.
2. Wechsler Memory Scale Face Memory Delay Test [ Time Frame: Pretest, Week 11, two-month follow-up ]
   A standardized measure of face memory in which the participant is exposed to 24 faces in which they must remember amidst an array of 48 faces presented immediately and after a 30-minute delay. Any increase in the raw score pertaining to the number of faces identified constitutes an increase in face memory.
3. Wechsler Memory Scale Face Memory Test [ Time Frame: Pretest, Week 11, two-month follow-up ]
   A standardized measure of face memory in which the participant is exposed to 24 faces in which they must remember amidst an array of 48 faces presented immediately and after a 30-minute delay. Any increase in the raw score pertaining to the number of faces identified constitutes an increase in face memory.
4. Adaptive Behavior Assessment System (ABAS) - Self-Report [ Time Frame: Pretest, Week 5, Week 11, two-month follow-up ]
   The ABAS measures adaptive living skills using a Standardized Scale in which scores from 85 to 115 reflect the broad average range. Lower scores represent greater impairment.
5. Adaptive Behavior Assessment System (ABAS) - Parent-Report [ Time Frame: Pretest, Week 5, Week 11, two-month follow-up ]
   The ABAS measures adaptive living skills using a Standardized Scale in which scores from 85 to 115 reflect the broad average range. Lower scores represent greater impairment.
6. State-Trait Anxiety Inventory (STAI) Scale [ Time Frame: Pretest, Week 11, two-month follow-up ]
   The STAI is a measure of current (State) and enduring (Trait) anxiety that is completed by the participant. There are 20 items for each domain on a 4-point scale (1 = Almost Never, 4 = Almost Always) and higher scores reflect greater anxiety.
7. The Adult Self Report (ASR) [ Time Frame: Pretest, Week 5, Week 11, two-month follow-up ]
   The ASR is the self-report of the Achenbach empirically system which covers emotional health. We will focus on the anxiety and depressive subscales. T-scores range from 40 to 100 with higher scores representing more impairment.
8. The Adult Behavior Checklist (ABCL) [ Time Frame: Pretest, Week 5, Week 11, two-month follow-up ]
   The ABCL is the care-giver-report version of the Achenbach system that covers emotional health. We will focus on the anxiety and depressive subscales. T-scores range from 40 to 100 with higher scores representing more impairment.
