Goal Attainment Scaling (GAS), a personalised, patient-generated outcome measure, enables individuals to define and evaluate progress toward meaningful goals. Evidence regarding its psychometric properties in dementia trials, however, remains limited.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To evaluate the feasibility, reliability, and validity of GAS within the randomised controlled trial of NIDUS-Family (New Interventions in Dementia Study), a goal-based psychosocial intervention.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>302 people with dementia and family carer dyads collaboratively set baseline goals toward supporting the person with dementia to live well at home. In a psychometric evaluation guided by the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) framework, we examined follow-up completion (measuring feasibility); rater agreement; intra-rater reliability; construct validity by assessing correlations between change in GAS and quality-of-life (DEMQOL-proxy and CarerQoL); and predictive validity by testing whether GAS change predicted living at home at 12\u00a0months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>GAS completion rates were 86% at 6\u00a0months and 82% at 12\u00a0months. GAS demonstrated excellent inter-rater (Intraclass Correlation Coefficient\u2009=\u20090.99) and intra-rater reliability (Cohen\u2019s kappa\u2009=\u20090.91). There were significant but weak positive correlations between GAS change and carer and person with dementia quality-of-life (r\u2009=\u20090.14\u20130.22). GAS change was associated with remaining at home (odds ratio 1.08 per point increase; P\u2009&amp;lt;.01).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>GAS is feasible, valid and reliable, so may be a sensitive and clinically meaningful candidate primary outcome for psychosocial dementia trials. Correlations with global quality of life were significant but modest, consistent with GAS capturing personalised rather than generic outcomes.<\/jats:p>\n
