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).
