A primary reason has been the lack of appropriate locally-validated outcome tools. This study aimed to validate a multidimensional scale the APCA African Palliative Outcome Scale in a multi-centred international study. Methods Validation was conducted across 5 African services and in 3 phases Phase 1. Face validity content analysis of qualitative interviews and cognitive interviewing of POS Phase 2. Construct validity correlation of POS with Missoula-Vitas Quality of Life Index Spearman s rank tests Phase 3. Internal consistency Cronbach s alpha calculated twice using 2 datasets test-retest reliability intraclass correlation coefficients calculated for 2 time points and time to complete calculated twice using 2 datasets . Results The validation involved 682 patients and 437 family carers interviewed in 8 different languages. Phase 1. Qualitative interviews N 90 patients N 38 carers showed POS items mapped well onto identified needs cognitive interviews N 73 patients N 29 carers demonstrated good interpretation Phase 2. POS-MVQoLI Spearman s rank correlations were low-moderate as expected N 285 Phase 3. N 307 2nd assessment mean hours after first SD Cronbach s Alpha was on both datasets indicating expected moderate internal consistency test-retest .
