Illness perceptions (Brief Illness Perception Questionnaire-Revised: BIPQR; Broadbent et al, 2006): The BIPQR includes eight items, of which five assess cognitive illness representations (consequences, timeline, personal control, treatment control and identity), two assess emotional representations (concern and emotions) and one assesses illness comprehensibility.
To assess the various dimensions of illness perceptions, the Brief Illness Perception Questionnaire (B-IPQ) [ 19] was used.
Questionnaires were sent to 989 patients to assess their perceptions about stroke (Brief Illness Perception Questionnaire, Brief IPQ), beliefs about medicines (Beliefs about Medicines Questionnaires, BMQ) and adherence to treatment (Medication Adherence Report Scale, MARS) 3 months after stroke onset.
The Brief Illness Perception Questionnaire (B-IPQ) assesses perception of illness by asking patients for their own belief about their condition [ 34].
Illness perceptions are assessed with the brief Illness Perception Questionnaire (brief-IPQ).
Illness perceptions were measured using the Brief Illness Perception Questionnaire (B-IPQ).
Illness perceptions were assessed using the Brief Illness Perception Questionnaire [ 30], which is a brief version of the Revised IPQ [ 31].
Illness perceptions: We assessed patients' perceptions about their health problems using the Brief Illness Perception Questionnaire (BIPQ), an instrument based on the work of Weinman [ 39 ] and then Moss-Morris [ 40 ], later adapted by Broadbent [ 41 ] (see Additional file 2, section E).
Using an adapted version for mosquito-borne diseases, health threat perceptions were first assessed with the Brief Illness Perception Questionnaire.
This measure has been shown to predict outcome for people with severe depression [ 14] and schizophrenia [ 15]. 4) The Brief Illness Perception Questionnaire [ 16] adapted from the original Illness Perception Questionnaire [ 17] measures the insight of participants into their relative's illness.
