ALSPAC – Focus on Mothers 4 – Verbal Fluency Test

The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed study mothers during the study’s fourth ‘Focus on Mothers’ clinic using a Verbal Fluency Test.

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 Verbal Fluency Test administered as part of FOM4 are outlined in the table below.


Domain:Verbal fluency
Measures:Verbal/semantic fluency
Associational fluency
Executive function
CHC:Glr (Long-Term Storage and Retrieval)
Administration method:Trained interviewer; face to face; clinical setting
Procedure:Participants were given one minute in which to say as many words as possible beginning with a specific letter. They were instructed not to include proper nouns (e.g. people or place names), numbers, repetitions or variations of the same word (e.g. see - seeing). Three trials were administered (letters 'C', 'F' and 'L'), each lasting one minute.
