Background: Review addresses evidence that supports employment supports for persons with autism spectrum disorders.

Objective: The objective of the review is to determine the effectiveness of adult employment interventions in securing and maintaining employment for adults with autism spectrum disorders.

Search Strategy: Comprehensive search of electronic and gray literature sources.

Selection Criteria: Studies were identified through independent reviews of two independent reviewers.

Data Collection and Analysis: Information retrieval activities identified 8,528 studies for the first stage review. Second stage review of 77 studies occurred. Two studies were found to meet the inclusion criteria.

Results: This review was not able to identify definitive interventions that predictably and positively supported the development of employment outcomes for individuals with ASD. There were two included studies. One, Mawhood and Howlin (1999), described outcomes directly related to employment by comparing an experimental group (n = 30) who received guidance from a support worker in the form of job finding, work preparation, and communication with the employers with a control group (n = 20) that did not receive any support. At the end of the two-year study period, the authors found that the experimental group demonstrated significantly higher rates of having found paid employment (d = 1.067, 95% CI = 0.123 to 2.010), significantly longer periods of working time (d = 0.684, 95% CI = 0.111 to 1.257), and significantly higher wages (d = 1.177, 95% CI = 0.169 to 0.819). The experimental group also worked more hours per work week (d = 0.328, 95% CI = -0.628 to 1.284), but this effect was not significant. The second included study, Garcia-Villamisar, Ross, and Wehman (2000), described differential effects of supported employment and sheltered employment for persons with autism. The experimental group received supported employment, i.e., jobs working between 15 and 30 hours per week in their communities and received job coach support services. The control group received sheltered employment, i.e., jobs that were not in their communities and with no job coaching services. Using measures of the Childhood Autism Rating Scale (CARS), the supported employment group was not significantly different from the sheltered employment group after treatment (d = -0.229, 95% CI = - 0.764 to 0.306). The study did not report any differences in employment acquisition or maintenance between the two groups. In an analysis of risk bias of the included studies, it was found that there was a high level of substantial potential for bias across three of the five sources of bias analyzed including unit of assignment, unit of analysis, attrition, fidelity of implementation, and blinding. The methodological quality of both included studies was low. Therefore, these review results should not be interpreted as indicating definitive results related to the development of employment outcomes for persons with ASD.

Authors Conclusion: Qualitative and other relevant research studies connected to the employment of persons with ASD were also reviewed and suggest that the following may be elements of successful employment placement for persons with ASD: (1) identification of the most appropriate work settings and placements, (2) provision of effective supports on the job, (3) need for long-term support services for the employer and the consumer, (4) costs for support, and (5) positive effects of employment on persons with ASD. While qualitative studies point to a number of promising issues for future research, they do not provide a definitive statement about what works. In addition, the authors noted that costs for community-based employment interventions such as those included in this review are more expensive than other employment alternatives such as sheltered non-integrated workshops. However, Howlin, Alcock & Burkin (2005) and others (e.g., Cimera & Cowan, 2009) show that supported employment service interventions, such as those identified in our included studies, are becoming less expensive to deliver. It seems important to note that community-based integrated employment interventions, while expensive, do expand options for mainstream social integration, competitive wages, and community involvement.

Plain Language Title

The effects of employment assistance services on employment outcomes for adults with autism: A systematic planned out, orderly, regular review

Review go over, check Question

Do employment assistance interventions help adults with autism brain disorder, illness that makes it hard for someone to talk to other people attain job placements?


Adults with autism brain disorder, illness that makes it hard for someone to talk to other people may face challenges in employment settings due to difficulties problems, trouble in social functioning. Certain employment interventions aim to make it easier for adults with autism brain disorder, illness that makes it hard for someone to talk to other people to secure and maintain take care of, keep, keep up jobs.

Search Date

The search covered the period sore, wound, infection from 1943 through 2008.

Study Characteristics

This review go over, check focused on employment interventions for adults 18 years or older with a diagnosis finding out the cause of an illness, condition, disease, medical answer of autism brain disorder, illness that makes it hard for someone to talk to other people spectrum disorder condition, illness, medical problem and who were no longer enrolled in school-to-work or high-school-level education programs. The review go over, check considered interventions that centered on competitive, supported, or integrated employment. It did not include interventions in which the treatment action, medicine, therapy groups were not in an integrated or mainstream form of employment. The search included both published and unpublished literature. Studies had to use randomized, quasi-experimental, or single-subject experimental designs. The review go over, check focused on one outcome, attainment of a job placement.

Key Results

The review go over, check only identified two relevant studies of low methodological quality. The review go over, check found no high-quality evidence of interventions that could reliably support employment for individuals with autism. brain disorder, illness that makes it hard for someone to talk to other people After reviewing additional extra, added, more studies that did not qualify for inclusion in the review go over, check (such as qualitative studies), the authors suggest that the following after may be elements of successful job placement for individuals with autism: (1) identifying the most appropriate take, take over, a good fit, proper, right work settings and placements, (2) providing effective works well, good, strong supports on the job, (3) the need for long-term for a long time, over a long period of time support services, (4) the costs of support, and (5) the positive impact of employment on individuals with autism. brain disorder, illness that makes it hard for someone to talk to other people Additional extra, added, more research is needed to identify effective works well, good, strong interventions.

Use of Statistics

The review go over, check reports detailed results from the two included studies.

Quality of Evidence

The main limitation of the review go over, check is the lack of relevant studies to include. The quality of the existing evidence on this topic is weak.
