The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) during the study’s age 17.5 sweep (TeenFocus 4) using a measure of Information Processing Biases (Affective Go/No-Go Task).
Details on this measure and the data collected from the CMs are outlined in the table below.
|Domain:||Information processing biases for positive and negative stimuli|
|Measures:||Executive control of positive and negative information|
|Administration method:||Trained interviewer; clinical setting; CAPI|
|Procedure:||This test required participants to differentiate between happy and sad words. Eight blocks of 18 words pertaining to emotions were presented. Single words appeared on the computer screen, and participants were instructed to hit the spacebar when a happy word appeared (e.g. hopeful, serene). After two word blocks requiring responses to happy words, the instructions changed so that the space bar was to be pressed for sad words. Instructions were alternated in this fashion until all eight blocks were administered. Words were presented for 300 msec, with a 900 msec interval between each word.|

|Scoring:||Mean RTs (reaction times) for hits (i.e., pressing the space bar in the presence of a target word), collapsed across valence and shift condition.|
|Item-level variable(s):||Not readily available|
|Total score/derived variable(s):||FJGO001 - FJGO1850|
|N = 2,485|
|Range = 155.38 - 764.07|
|Mean = 517.38|
|SD = 66.94|

|Age of participants:||Mean = 213.59 months, SD = 5.46, Range = 195 - 240|
|Other sweep and/or cohort:||None|
