These changes are often small to start with, but for someone with dementia they have become severe enough to affect daily life.

A person with dementia may also experience changes in their mood or behaviour.

Dementia is caused when the brain is damaged by diseases (plaques and tangles), such as Alzheimer’s disease or a series of strokes. Alzheimer’s disease is the most common cause of dementia, but not the only one.

Also as they may find it difficult to fill out the form anyway as they may be generally confused and find concentrating on the form very hard. ]]> 2019-01-31 14:23:41 UTC https://padlet.com/harriet160897/3des6mc4qkfa/wish/326274514 How might the condition affect the psychometric properties of the scale that you use? harriet160897 https://padlet.com/harriet160897/3des6mc4qkfa/wish/326274775 It should be a short and very easy to understand scale. meaning there should be clear instructions for what the participant is expected to do. Also if possible the carer could give the scale to the participant in order to help the participant. 

Consider test-retest reliability as individuals with dementia may change from day to day depending on their severity]]> 2019-01-31 14:24:11 UTC https://padlet.com/harriet160897/3des6mc4qkfa/wish/326274775 Who is Administering n08282191 https://padlet.com/harriet160897/3des6mc4qkfa/wish/326276003 Scales should consider who is administering it as difference in results can be a result of if the person administering it has dementia, is a caregiver, doctor etc.

Moreover, it is important to consider self-report scales and the level of dementia severity of the patient]]> 2019-01-31 14:26:37 UTC https://padlet.com/harriet160897/3des6mc4qkfa/wish/326276003 Physical Properties of the Scale n08282191 https://padlet.com/harriet160897/3des6mc4qkfa/wish/326283187 Not having downward lines in the scales to make it easier to read from left to right. The downward lines can cause a visual separation between the response options causing confusion. 

Scale shouldn't be long winded in order to keep patient engaged with it. 

Not using common psychological phrase like 'sense of self' as while these are very common to psychologist they can be very confusing for older adults.]]> 2019-01-31 14:41:04 UTC https://padlet.com/harriet160897/3des6mc4qkfa/wish/326283187
