ALSPAC – Focus on Mothers 2 – Digit Symbol Coding

Scoop.it ShareThis

The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed study mothers during the study’s second ‘Focus on Mothers’ clinic using a Digit Symbol Coding measure.

The study of ALSPAC study mothers began in 2008 with the aim of determining what factors are related to body size, bone density, blood pressure, glucose, insulin and abnormal blood lipids in women. This ‘Focus on Mothers’ (FOM) study consisted of four clinics held during the following periods: i) 2008 – 2011, ii) 2011 – 2013, iii) 2013 – 2014, and iv) 2014 – 2015. Each clinic lasted approximately 2.5 hours. For further details see Fraser et al. (2012). Along with various physical measures, measures of cognitive ability/functioning were collected at clinics FOM2, FOM3, and FOM4.

Details on the Digit Symbol Coding measure administered as part of FOM2 are outlined in the table below.
