Topic: Risk, prevention and care in population studies
Objectives To develop a questionnaire that will capture patients' attitudes about dementia screening in primary care. Methods Cross-sectional study of 315 patients aged 65 and older attending urban and rural primary care clinics in Indianapolis and North Carolina. The Perceptions Regarding Investigational Screening for Memory in Primary Care (PRISM-PC) questionnaire was administered via face-to-face or telephone interview. Results The PRISM-PC questionnaire consists of two separate scales: the patient's acceptance of dementia screening scale and the patient's perceived harms and benefits of dementia screening scale. The face validity of the PRISM-PC questionnaire was based on a systematic literature review and the opinions of 16 clinician-investigators with experience in screening for dementia. Exploratory factor analyses for the acceptance scale revealed the presence of two dimensions: knowledge about dementia risk and testing for dementia. For the benefits and harms scale, exploratory factor analyses identified four dimensions: perceived benefits of screening, stigma of screening, suffering from screening, and impact of screening on patients' independence. The internal consistency of each of the above subscales was good with Cronbach's alpha ranging from 0.58-0.85. Conclusion The PRISM-PC questionnaire captures primary care patients' acceptance, perceived harms, and perceived benefits of dementia screening.
Key findings
- Results The PRISM-PC questionnaire consists of two separate scales: the patient's acceptance of dementia screening scale and the patient's perceived harms and benefits of dementia screening scale.
- Exploratory factor analyses for the acceptance scale revealed the presence of two dimensions: knowledge about dementia risk and testing for dementia.
Why it matters
This study developed and tested a questionnaire to measure primary care patients' attitudes about dementia screening. It is about measuring attitudes toward screening, not about treating, curing, or preventing Alzheimer's disease.
