Identify the type of study design needed, including within or between groups where relevant.

Identify and justify all relevant factors/independent and dependent variables. Identify and justify the correct test required.

The hypothesis

H1, people who attend a 12-week counselling programme will have higher levels of cognitive rumination than those who attend a 24-week programme.

H2, the levels of improvement in cognitive rumination will depend not only on the amount of counselling( 12 or 24 weeks) but also whether the counselling took place within a residential treatment facility or as an outpatient of the same facility.

Any assistance with this would be greatly appreciated.
