Abstract The involvement evaluation questionnaire (IEQ) was created to evaluate the caregiver's experience of burden and the consequences of providing care to people with psychotic disorders. To date, the IEQ has not been validated with caregivers of people diagnosed with borderline personality disorder (BPD). The main objective of the study was to confirm the psychometric properties and factorial structure of the Spanish version of the IEQ in 151 caregivers of people with BPD, with an average age of 54.52 ( SD = 9.91). Two models were tested by means of confirmatory factor analysis, following the original factor structure. The Models 1 and 2 displayed adequate fit, with comparative fit index and Tucker‐Lewis index > 0.90 and root‐mean‐square root of approximation < 0.08; however, Model 2 was more parsimonious. The Cronbach's alphas are adequate, ranging from 0.70 to 0.85. The consequences of providing care to people with BPD had a low or moderate association with the Level of Expressed Emotion scores. IEQ scores of caregivers of people diagnosed with BPD with psychiatric comorbidity did not differ from those of caregivers of people diagnosed with BPD without psychiatric comorbidity. The IEQ has adequate psychometric properties and can be utilized to assess burden in caregivers of people with BPD.
