Q

Evaluate the generalisablity using a low point.

A

P - Low
E - Whist the sample size, being 275, was large, they consisted of male offenders from Oregon
E - Ethnocentric and androgenic and so don’t represent wider society such as European countries and women

Q

Evaluate the reliability using 2 high points.

A

P - High
E - Research is backed up by other studies such as Emory 1992 who found that such treatment lowered sexual interest of the patients
E - Therefore there is consistency in findings which strengthens conclusions
P - High
E - Research uses quantitative data of recidivism rates and amount who committed new offences
E - This is objective and easy to compare

Q

Evaluate validity using a high and low point.

A

P - High
E - Variety of different measures when looking at outcome data including whether offenders were ‘doing well’ and whether they were ‘back in prison’
E - This meant that the outcomes focused on more than just recidivism and provided rich and valid data into the use of MPA
P - Low
E - Supervisors were asked if the offenders were ‘doing well’
E - This may involve subjectivity as they interpret their wellbeing which may be influenced by if they re-offended
