At Wave 5 and Wave 6, the youth questionnaire examines how to adapt questions on satisfaction for children, focusing on the use of pictorial evaluations of feelings. A split-ballot design was incorporated in the Waves 5 and 6 youth questionnaire where half of the child self-completion uses smiley faces for the questions on satisfaction in different domains, and the other half use a scale with a textual description but no smiley faces. Within PSUs, households were randomly allocated to experimental treatment all youth aged 10-15 within households received the same treatment:
Group 1 Smiley faces
Group 2 Text descriptions.
The experiment is controlled in Wave 5 by the variable e_ff_smilesw5 on record e_hhsamp_ip and in wave 6 by the variable f_ff_smilesw5 on record f_hhsamp_ip. The affected variables in Wave 5 are e_yphsw, e_yphap, e_yphfm, e_yphfr, e_yphsc, and e_yphlf on record e_youth_ip. Comparable affected variables in Wave 6 are f_yphsw, f_yphap, f_yphfm, f_yphfr, and f_yphsc.
