Abstract
Purpose
The OUT-PATSAT35 CT questionnaire evaluates satisfaction with care expressed by cancer outpatients receiving chemotherapy. This study assesses the psychometric properties of the OUT-PATSAT35 CT when applied to a sample of Spanish patients.
Methods
One hundred seventy-six patients with different tumour sites and disease stages completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ)-C30, the OUT-PATSAT35 CT, the Oberst patients’ perception of care quality and satisfaction scales (OS) and the item on intention to recommend the hospital (IR). Psychometric evaluation of the structure, reliability and validity of the questionnaire was conducted.
Results
Multitrait scaling analysis showed that 32 of 34 item-scale correlation coefficients met the standards for convergent validity and that many of them met the standards for discriminant validity. Cronbach’s coefficients were good (0.78–0.97) for all scales except doctor availability and environment. Correlations between the QLQ-C30 and the OUT-PATSAT35 CT were low (≤0.40). Correlations between IR and the OUT-PATSAT35 CT were moderate, and correlations between this questionnaire and the OS were fairly low. Areas whose contents were more related had higher correlation coefficients (>0.50) and vice versa (<0.1). Male patients, elderly patients, those with higher education levels, those with higher scores in four OS and patients who had not received surgery showed higher satisfaction with care in several OUT-PATSAT35 CT areas.
Conclusions
The OUT-PATSAT35 CT is a reliable and valid instrument when applied to a sample of Spanish cancer patients. These results are in line with those of the validation study conducted by the authors of the questionnaire and with the validation study for Spain of the OUT-PATSAT35 RT.
