Definition of 'disability'

The definition

A person is "disabled" for the purpose of the DDA if he has a "disability" as defined.

Many people with a stammer would not see themselves as "disabled" at all - see Reluctance to be seen as 'disabled'. However, the words 'disability' and 'disabled person' are given a special meaning under the DDA and what matters is whether you fall within this statutory definition rather than whether you would generally be considered by yourself or others as disabled.

Under section 1 # of the Act a person has a disability:

"if he has a physical or mental impairment which has a substantial and long-term adverse effect on his ability to carry out normal day-to-day activities."

Much of this definition will be met by any normal stammer (see below), so the issue tends to boil down to whether the person's stammer has a substantial effect on his ability to carry out normal day-to-day activities.

The basic definition above is modified by various detailed provisions in DDA Schedule 1. In the case of stammering, Schedule 1 tends to make the definition wider rather than narrower.

I'll now go into the various elements of the definition:

Physical or mental impairment

It seems clear that a stammer is a 'physical or mental impairment'. See 'Physical or mental impairment'...

Example from 2006 Guidance
In para D25(1): "A man has had a stammer since childhood. He does not stammer all the time, but his stammer can appear, particularly in telephone calls, to go beyond the occasional lapses in fluency found in the speech of people who do not have the impairment. However, this effect can often be hidden by his coping strategy. He may try to avoid telephone calls where he believes he will stammer, or he may not speak as much during telephone calls. He may sometimes try to avoid stammering by substituting words, or by inserting extra words or phrases.

...[Two non-stammering examples follow]...

"In these cases it would be reasonable to regard these effects as substantial adverse effects."

Substantial adverse effect

This is the key issue for whether a particular stammer falls within the DDA. 'Substantial' means only 'more than minor or trivial' so the threshhold is a low one.

The most obvious kind of effect is just stammering openly. The key question here is: What is substantial? - see Substantial effect - overt stammering.

However there are also likely to be relevant effects where one hides one's stammering, through avoidance/concealment strategies such as substituting words or staying out of difficult situations - see Hiding the stammer.

Effects may be relevant even if they are not apparent because one uses speech techniques, or an electronic device (Schedule 1 para 6(1)) - see Therapy.

A stammer which does not currently have substantial adverse effects is seen as continuing to have them if they are likely to reoccur (Schedule 1 para 2). See Longer-term variations.

The effect must by on (ability to carry out) 'normal day-to-day activities'

This will not normally a problem. See 'Normal day-to-day activities'.

The effect must be 'long-term'

Broadly speaking, the effect of an impairment is treated as long-term if it lasts or is likely to last at least twelve months (Schedule 1 para 2(1) #). Unfortunately, a stammer will normally meet this requirement.

An impairment which ceases to have a substantial adverse effect is treated as continuing if it is likely to recur (Schedule 1 para 2 #). See Longer-term variations.

List of capacities

Under DDA Sch 1 para 4, an impairment is to be taken to affect the ability of the person concerned to carry out normal day-to-day activities only if it affects one of various listed capacities. These include speech (item (f)) so it is not a problem for stammering.

Past disability

Even if an impairment no longer has substantial adverse effects, it can be relevant as a 'past disability. See Longer-term variations.
