Table 1 Characteristics of the VISTA and MGAT studies

From: The responsiveness of goal attainment scaling using just one goal in controlled clinical trials: an exploratory analysis

 Video-Imaging Synthesis of Treating Alzheimer’s Disease (VISTA)Mobile Geriatric Assessment Team (MGAT)
DesignDouble-blind, placebo controlled RCTSingle-blind RCT – Assessments were performed by healthcare professionals blind to patient status
ParticipantsCommunity-dwelling adults with mild to moderate Alzheimer’s Disease (n = 130)Rural, community-dwelling, frail elderly patients (n = 182)
InterventionPatients were randomized to receive either galantamine (16–24 mg/d) or a placebo for a 4-month periodPatients were randomized to receive either usual care by family physicians or care in which physician efforts were supplemented by a specialized geriatric intervention over a 3-month period
Primary Outcome MeasureGoal Attainment Scaling (GAS)Goal Attainment Scaling (GAS)
GAS MethodologyAssessment:
Two independent GAS assessments were conducted at each time-point.
- Patient/caregiver-rated GAS was assessed in a clinician-facilitated interview
- Clinician-rated GAS was assessed following interviews with patients and/or caregivers.
Assessment:
Patient-rated GAS was assessed in a clinician-facilitated interview both at baseline and three-month follow-up
Goal setting:
Goals were freely selected based on symptoms considered important to the patient
Goal setting:
Participants selected goals based on a list of 42 symptoms or problems identified by the Comprehensive Geriatric Assessment (CGA)
Goal weighting:
Patients and caregivers ranked (weighted) their goals in order of importance.
Clinicians did not rank goals, so all were assigned a weighting of ‘1’
Goal weighting:
As goals were not ranked, all were assigned a weighting of ‘1’
Baseline scores:
Baseline raw GAS scores set at ‘0’
Baseline scores:
Baseline raw GAS scores were set at ‘-1’, except for a small number of participants (n = 5). These participants were assigned baseline scores of ‘-2’ based on the clinical judgement that their situation could not plausibly deteriorate.
Goal selection for one-goal GAS:
One-goal GAS scores were derived for patients/caregivers using their highest-ranking goal
One-goal GAS scores were derived for clinicians by selecting the first goal listed for each patient
Goal selection for one-goal GAS:
One-goal GAS scores were derived by randomly selecting a goal for each participant using a custom excel macro
 Number of Goals Set:
The median number of goals set was 3 (range 1–6)
Number of Goals Set:
The median number of goals set was 5 (range 2–15)
