Use of the Interact Short Form as a tool to evaluate emotion of people with profound intellectual disabilities.

BACKGROUND
One of the essential purposes of intervention programmes for people with profound intellectual disabilities (ID) is to enhance the desirable mood and behaviour and decrease the undesirable ones through stabilizing their emotion. There is lack of validated instrument to offer a comprehensive measure that covers the mood and behaviour, both desirable and undesirable, appropriate for people with profound ID.


METHOD
This study aimed to examine the validity and reliability of the Interact Short Form for evaluating the mood and behaviour of people with profound ID, and at the same time, review their emotional profile using the Interact Short Form. Both content validity using expert panel review and construct validity by means of factor analysis were investigated. A total of 75 people with profound ID were recruited. Inter-rater reliability was tested. The results of the Interact Short Form were described to reflect the emotional profile of this group of participants.


RESULTS
Using the results of expert panel review and those from factor analysis, we found three subscales representing the mood and behaviour of people with profound ID. They were: 'emotional expression', 'interests towards tasks' and 'behaviours to environment'. All three subscales were found to be internally consistent (alpha = 0.71-0.88). The Interact Short Form- People with profound ID version also showed good inter-rater reliability (mean = 0.72). The results of the Interact Short Form showed that this group of participants had fairly stable emotion under the structured setting and activities in the residential institutions where data were collected.


CONCLUSIONS
The Interact Short Form- People with profound ID version serves as a helpful tool for both clinical and research use in assessing the mood and behaviour of people with profound ID in a simple, comprehensive and systematic way.
