"An overall Malaise score ... is the sum across the individual variables"

In the BCS70, all 24 'yes-no' questions were asked in the standard way at age 26 and age 30 but at age 34, just 9 of the 24 questions were asked (again in the standard 'yes-no' format).

However, when BCS70 cohort members were aged 16 they were asked 22 of the 24 questions and a three answer category approach was adopted:

  • 0='rarely/never'
  • 1='some of the time'
  • 2='most of the time'

When questions are asked in the standard format:

  • 1 point is awarded for every 'yes' response
  • 0 points for every 'no' response.

An overall Malaise score for a cohort member is the sum across the individual variables, yielding a minimum score of 0 and a maximum of 24.

A score of 8 or higher is considered to be a sign that the cohort member is experiencing symptoms associated with depression.

When only 9 questions were included, a score of 4 or higher is considered to be a sign that the cohort member is experiencing symptoms associated with depression.

The overall Malaise score range for BCS70 cohort members at age 16 (when a three answer category approach was adopted) has a minimum of 0 and a maximum of 44. A score of 15 or higher is considered to be a sign that the cohort member is experiencing symptoms associated with depression.
