Employment is crucial in the lives of adults with Autism Spectrum Disorder (ASD) as gainful occupational activity creates opportunities to form meaningful social relationships, participate in community life, and become financially independent. Impairments in pragmatic language skills (i.e., use of language to achieve social goals) negatively impact the ability to make and maintain cooperative work relationships with employers and coworkers, which are critical aspects of employment. A specific pragmatic skill key to workplace communication includes using a suitable degree of politeness, loosely defined as demonstrating the appreciation of the thoughts and feelings of your listener. Politeness can be measured with politeness markers (PMs). Appropriate PM use promotes positive, cooperative relationships. There are two main categories of PMs: positive and negative PMs. Positive PMs express appreciation or praise to the listener. Negative PMs avoid conflict and marks consideration of the thoughts and feelings of the listener. Crucially, negative PMs require more monitoring of social boundaries as they require consideration of the conversational partner’s potential reactions to statements and their emotional states. This makes PMs a novel new approach to evaluating speech in persons with ASD. Because PMs serve a purely social function in language, they include non-tangible words, such as would, could, may, or might. The current study explores the utility of an employment-specific social communication assessment tool, the Voicemail Elicitation Task (VET), in persons with ASD. The VET has proven sensitive to identifying social communication deficits in persons with traumatic brain injury.

The current cohort comparative study included a sample of young adults with ASD (n=22) and neurotypical controls (NTC; n=10). All participants were given the VET, which utilizes a standardized computerized language sampling procedure that assesses politeness markers (PMs) in work-related role-play scenarios. The outcome measure of the VET is PMs per minute (PMpM) which is obtained by dividing the sum of PMs by the speaking time (in minutes). Higher PMpM indicates higher PM use (more politeness), while lower PMpM indicates lower PM use (less politeness).

The preliminary results indicated a significantly lower total PMpM in ASD participants (mean: 13.68 SD: 6.28) compared to NTCs (mean 18.72, SD: 3.65), p = 0.026. Post hoc analysis indicated that the differences in groups were driven by significantly lower negative PMs rates used by the ASD group (mean 9.18, SD: 5.77) compared to NTCs (mean: 16.30, SD: 7.78), p = 0.002, while both groups were similar in their mean level of positive PMs use, p = 0.442.

This study represents an important step toward validating the VET for use in ASD, which will improve the capacity of the field to address unemployment in this population. The results of the current study indicate that individuals with ASD show deficits in PM use which could impact their interpersonal relationships within the workplace environment. Designing interventions to target these deficits could help provide better employment outcomes for this population.
