ALSPAC – Age 11.5 – Test of Everyday Attention for Children (TEA-Ch) Sky Search

The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) during the study’s age 11.5 sweep (Focus 11+ Clinic) using the Sky Search measure from the Test of Everyday Attention for Children (TEA-Ch).

Details on this measure and the data collected from the CMs are outlined in the table below.

Years of data collection:	2003-2005
Domain:	Attention
Measures:	Selective attention
	Concentration
	Mental speed
	Visual scanning
CHC:	Gs (Processing Speed)
	Gps (Psychomotor Speed)
	Gv (Visual Processing)
	Gsm (Short-Term Memory)

Administration method:	Trained interviewer; clinical setting; pen and paper
Procedure:	The child was presented with an array of non-identical and identical spaceships, and was tasked with circling pairs of identical spaceships as quickly as possible, whilst trying to avoid any errors. The interviewer demonstrated, and the child worked through a practice sheet. After the practice sheet, the child was presented with larger sheet and asked to do the same (20 identical pairs). The amount of time taken was recorded in seconds.
	The above task was repeated, without the non-identical pairs of ships. The aim was to identify how quickly the child could complete the task, in order to control for motor performance.

Scoring:	Three summary scores are provided:
	i. Unadjusted score: time taken (in seconds) for the search task divided by the number of spaceship pairs correctly circled
	ii. Motor score: time in seconds for the motor task divided by number of correct pairs
	iii. The adjusted score is calculated by subtracting the motor score from the unadjusted score, thus controlling for motor speed
Item-level variable(s):	Not readily available.
