ABSTRACT: Background: Among elderly people, rehabilitation is important
for reducing the risk of falls and hospitalization and to maintain an
independent life for longer. Motivation is a factor for elderly people to lead
an active daily life and leave home more frequently. Purpose: The purposes of this study were to determine the
optimal cut-off point in the Scale for Achievement Motive in Geriatrics (SAMG)
that could identify individuals as inactive or active, based on the Frenchay
Activities Index (FAI), and to compare characteristics between active and inactive
groups classified by the cut-off point. Methods: A cross-sectional study of 285 community-dwelling
elderly people measured SAMG and FAI and physical function. Receiver operating
characteristic (ROC) analysis was used to calculate the area under the curve
(AUC) that was the optimal cut-off point for the SAMG total score, with the
associated sensitivity and 1-specificity when compared with the FAI results.
Demographic parameters and physical function were compared between two groups
defined by cut-off point. Results: The AUC was 0.78, the optimal cut-off for SAMG
total score for indicating inactivity was ≤48, the sensitivity was 77.98% and
the 1-specificity was 75.00%. The group with SAMG score >48 was
characterized by a significantly higher proportion of women, fewer people
sharing a house, and participation in more hobbies. Discussion: A cut-off point of 48 in the SAMG could be a predictive
index of motivation toward goals for individuals with inactive daily activities.
The group with score higher than the cut-off was characterized by more women,
fewer people living together, and more hobbies than the group with lower
scores.
