Outcome Measure

Description

Explanation

Primary

Functional status – observed

Short Physical Performance Battery (SPPB) score [16, 17]

SPPB group and summary scores show a clear gradient. Lower scores correlate with higher mortality rates and nursing home admissions.

 

Functional status- self report

Nottingham Extended Activities of Daily Living Scale (NEADL) score [37]

A well validated measure of self report functional status that is sensitive to change.

Secondary

Depressive symptoms

Geriatric Depression Scale (GDS-15) score

An extensively used and well validated scale [38]. It can be used both as a screening tool for depression and as a measure of change of symptoms [43, 44]. GDS-15 = 5 indicates significant depressive symptoms.

 

Quality of life

SF-36 score [39]

This validated measure evaluates eight subscales of health-related quality of life.

 

Physical Activity

Auckland Heart Study (AHS) Physical Activity Questionnaire score [40, 45].

Validated [45] self- report questionnaire.

 

Falls and injuries

Self-reported falls and injuries in the last 12 months. Medical treatment for injuries from falls

This will help determine if falls are reduced or increased by the programme (ie: a potential harm).
