Validity and reliability of classification and diagnosis of sz Flashcards
what are the 3 peels to assess the validity and reliability of classification and diagnosis of sz
weakness - symptom overlap
weakness - co morbidity
weakness - gender bias
P
(symptom overlap)
weakness - symptom overlap
E
this is where 2 or more conditions share similar symptoms, e.g. sz and dep both share neg. symptoms of avolition
E
this questions the validity and reliability of classification and diagnosis of sz as an indv may be misdiagnosed. this is an issue as docs may be misdiagnosing sz so indv may not receive appropiate treatment
L
therefore this weakens the validity and reliability of classification and diagnosis of sz as it negativly affects its accuracy
P
(co - morbidity)
weakness - co morbidity
E
this is where 2 illnesses occur at the same time
E
e.g. in a piece of research, 50% of patients diagnosed with sz were also diagnosed with depression and ocd
L
this questions the validity and reliability of classification and diagnosis of sz as the 2 conditions may be seen as one and doctors could misdiagnose
P
(gender bias)
weakness - gender bias in diagnosis
E
since 1980s men have been diagnosed with sz more than women. this may be because men are more genetically vulnerable to developing sz.
E
or it could be because females with sz typically function better than men, e.g being more likely to work or have good family relationships therefore they can hide symptoms better
L
this questions the validity and reliability of classification and diagnosis of sz as women who share similar symptoms as men may not receive the same diagnosis as symptoms could be seen as mild
