Factor structure of the Spanish version of the Revised Illness Perception Questionnaire in a sample of subjects with hypertension. The Revised Illness Perception Questionnaire -IPQ-R- was designed to assess the cognitive and emotional domains of illness representations in the common-sense model of self-regulation. The IPQ-R contains three sections. Two scales measuring identity and causal dimensions and a remaining section assessing timeline acute/chronic, timeline cyclical, consequences, personal control, treatment control, illness coherence and emotional representations dimensions. The main purpose of the present study was the analysis about the factor structure and reliability of the the Spanish version of the IPQ-R in a sample of 170 patients with hypertension (27-75 yrs old). The analysis revealed five factors which accounted for 67,33% of the variance of the causal items and a five-factor solution including control, coherence. timeline cyclical. timeline acute/chronic and emotion dimensions (76,89% of the variance). Internal consistency for the IPQ-R subscales were adequate.
