Findings demonstrated that vocabulary interventions for children who are deaf and hard of hearing were associated with:<br />
<ul>
<li>improved expressive and receptive oral vocabulary, with a benefit of multisensory approaches;</li>
<li>improved sign vocabulary, with a potential benefit of using digital devices;</li>
<li>improved written vocabulary with co-speech signs; and</li>
<li>no improvement in general vocabulary for interventions using video with subtitles.</li>
</ul>
However, these results should be interpreted with caution due to small sample sizes within various meta-analyses and a lack of clearly defined or valid control groups. Further research is indicated.
