- the prevalence of symptoms in the sample
- the effect of ADHD severity on symptoms (correlation?)
- the effect of quality of life on the presence of the symptoms
- the effects of the variables of age, age at diagnosis, gender, medication use, siblings, and siblings having a learning disability on the presence of symptoms (multiple regression?)
I would really appreciate if you were able to help me with this!! Very confused and getting very stressed about it!
I think a little more detail is needed.Would i be right in saying that you would start with your hypotheses, eg. learning disablity such as Dyslexia/Dysgraphia has a significant affect on the maintenance of symptoms of adhd, this would however be quite hard to carry out, itd be long term as the prevalence of adhd would have to be measured at different intervals and even then you would you have to take various measure to suggest that its the learning disorder having an affect on adhd.
youd have to start by quantifying each of these concepts eg. ones quality of life, age at diagnosis, ADHD severity, symptoms...... using verfiable or standardised tests/surveys/questionaires and then placing them against eachother in correlations/ regressions etc...to essentially suggest theres a relationship between them.
if you are not intending on quantifying any of these though its qualitative research you're lookin at, and in that case spss is no use.
