Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary parameters of interest are the YSQ and SMI, in order to validate these instruments. The YSQ and SMI are self-report questionnaires. Within a subgroup of 60 patients, the YSQ and SMI will be re-administered within one week to examine the test-retest reliability. For the second question, schema activation (YSQ scores) among nursing home residents will be examined by comparing cases and controls, stratified for the presence of a psychiatric disorder using multivariate analysis of variance adjusted for potential confounders/group differences. | — |
Secondary
| Measure | Time frame |
|---|---|
| To examine the convergent and divergent validity, sociodemographic characteristics, personality functioning, early traumatization, (instrumental) activities of daily living, alcohol use, psychological distress, mental wellbeing, and cognitive functioning will be assessed with well-validated questionnaires for older people. Used are self-report questionnaires, and two brief neuropsychological screeners. All are administered by the researcher. | — |
