Caregiver Illness Perceptions
The Illness Perception Questionnaire - Revised
(IPQ-R)25 measures the components of illness beliefs
detailed in Leventhal’s CSM. It includes 9 subscales: Identity, timeline
acute/chronic, timeline cyclical, consequences, personal control,
treatment control, emotional representations, illness coherence, and
causes (see supplement table a). In line with author guidelines, the
IPQ-R was adapted for the parent’s perception of eczema therefore, ‘my
illness’ was replaced with ‘my child’s illness’ and/or ‘their eczema’.
In the current study, internal consistency ranged from acceptable to
excellent (Cronbach’s α=0.70 to 0.94). Subscales in the acceptable range
were timeline cyclical (α=0.70) and treatment control (α=0.77).
