howell used questionaires wich included the novaco anger scale on the type and strenght of anger shown. this yeilded quanataive data wich is objective and easy to analyse
how does the idea of yeilding qualataive dat imorove howells study
t/f the findings on the role of amp in treating criminal offenders is objective and easy to analyze increasing the validity of the findings
what is a weakness of howells study
population validity
how is population validity a weakness
howell use 418 male offenders detained in prison. the study and all pp originated from australia

t/f this is an andro and ethnocentric sample meaning the findings on the effectivness of amp inn reducing anger in offenders is ungeneralisable to a wider population
what is anouther strength of howell
mundane realism
how is mundane realism a strength
all data obtained was naturally occouring within the amp that the offenders where compleating as part of prison activities
what does mundane realism mean for the study
t/f increasing the ability for offender to controll their anger and behaviour from the skills learnt in amp was naturally occouring and can be generalised to anger managment in everyday life
what is anouther weakness of howell
cause and effect
how is cause and effect a weakness
as the data gathered on the offenders was taken during their time in prison when they where completing amp, and so may have shown social desirability bias as they wanted to exhibit less agressive behaviour and controll their anger inorder to be released from prison earilier
how does cause and effect oppose howell
t/f the findings of amp in being able to improve control over anger in offenders lacks validity
