Introduction<br />

We read, and considered, f<strong>in</strong>d<strong>in</strong>gs from a wide range of studies and <strong>in</strong>ternational evidence reviews<br />

identified through journal and database searches at the NCSE along <strong>with</strong> two peer-reviewed<br />

studies commissioned by the NCSE; a number of <strong>in</strong>ternational cl<strong>in</strong>ical guidance documents; as<br />

well as many other papers and studies identified by stakeholders and brought to the attention of<br />

the NCSE dur<strong>in</strong>g the consultation process around develop<strong>in</strong>g this policy advice, many of which are<br />

<strong>in</strong>cluded <strong>in</strong> the accompany<strong>in</strong>g bibliography.<br />

Despite limitations <strong>in</strong> the research identified across these reviews (see Section 2.4.3 for further<br />

discussion), their f<strong>in</strong>d<strong>in</strong>gs have identified a range of <strong>in</strong>terventions from different theoretical<br />

perspectives that can be effective <strong>in</strong> certa<strong>in</strong> ways for some children and young people <strong>with</strong> ASD.<br />

For <strong>in</strong>formation, the <strong>in</strong>terventions are listed and described later <strong>in</strong> Appendix 5.<br />

These <strong>in</strong>terventions will, unfortunately, not be equally effective for all students. It is clear that some<br />

may respond well <strong>with</strong> a particular <strong>in</strong>tervention or <strong>in</strong>terventions while others may not. Research<br />

evidence is limited on the factors that predict which students will have positive or negative outcomes<br />

(although cognitive and verbal ability have been identified <strong>in</strong> some studies as factors that may be<br />

significant <strong>in</strong> predict<strong>in</strong>g outcomes <strong>in</strong> certa<strong>in</strong> cases) or what the long-term ga<strong>in</strong>s from <strong>in</strong>terventions<br />

might be or what <strong>in</strong>terventions might work well <strong>with</strong> older age groups. F<strong>in</strong>ally it is acknowledged<br />

<strong>in</strong> the literature that while an <strong>in</strong>tervention may have no evidence of effectiveness, this does not<br />

necessarily mean it is <strong>in</strong>effective (unless of course there is direct evidence of <strong>in</strong>effectiveness). It<br />

may be the case that some <strong>in</strong>terventions have not yet been sufficiently researched to establish<br />

an evidence base. For this reason, some systematic reviews also identify <strong>in</strong>terventions which<br />

have ‘emerg<strong>in</strong>g’ or ‘<strong>in</strong>sufficient’ evidence of effectiveness. But it is possible that follow<strong>in</strong>g further<br />

research such <strong>in</strong>terventions may be deemed by future reviews to have accumulated evidence of<br />

effectiveness.<br />

1.5 Prevalence<br />

Increases <strong>in</strong> ASD prevalence have been well documented <strong>in</strong> recent decades and may have been l<strong>in</strong>ked<br />

to changes <strong>in</strong> diagnostic practices, service availability and greater awareness of autism spectrum<br />

disorders. There had been some <strong>in</strong>ternational agreement that ASD prevalence rates were about 1<br />

per cent, but some recent reports suggest a higher rate, for example, the US Centre for Disease<br />

Control and Prevention 9 reports that about 1 <strong>in</strong> 68 or 1.6 per cent of children/young people have<br />

been identified <strong>with</strong> ASD; UK analysis of the Millennium Cohort Study 10 (six- to eight-year-olds <strong>in</strong><br />

England, Wales, Scotland and Northern Ireland) showed that 1.7 per cent were reported as hav<strong>in</strong>g<br />

ASD at mean age 7.2 years; figures from the Northern Ireland school census 11 show the estimated<br />

prevalence of ASD to be at 2 per cent among children and young people aged 4 to 15 years. Boys<br />

are up to five times more likely to be affected by ASD.<br />
