The construction phase began with a determination of the questionnaire
items, which was based on three resources: (1) the current literature on
time use, time management, and executive functions, with an emphasis on
organisational ability among adults; (2) structured interviews with 10 adults
about their everyday activity performance and participation, following their
own characterisation of their performance as disorganised; and (3) previous
interviews conducted by the researcher with adolescents and adults coping
with learning difficulty (LD), attention deficit hyperactivity disorder
(ADHD), and developmental coordination disorder (DCD) (Kirby et al.,
2010; Rosenblum & Weintraub, 2007).
