The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) at 18 months’ age (Children in Focus Clinic) using the Griffiths Scales of Mental Development (GSMD) Personal-Social Scale.
Details on this measure and the data collected from the CMs are outlined in the table below.
| Domain: | Verbal and non-verbal social skills | |
| Measures: | Personal/social skills | |
| Genera verbal information | ||
| Listening ability | ||
| CHC: | Gkn (General domain-specific knowledge) | |
| Gc (Crystallized Intelligence) | ||
| Administration method: | Trained interviewer; clinical setting; guided play session | |
| Procedure: | During a guided play session, the interviewer noted (yes/no) whether the child was capable of performing tasks ranging in difficulty from 'Puts small objects in and out of cup in play' to 'Begins to co-operate in play with other children'. Also included a number of acquired knowledge items, e.g. "Where are the dolly's hands, etc." | |
