The Development of Simple Screening Tool for Predict Risk of Falls in Thai Community-Dwelling Elderly
Objective:
To develop and examine the psychometric properties of the Three Times Sit-to-Stand Test (TTSST) to evaluate its functional capacity and to predict the risk of fall in community-dwelling elderly.
Material And Method:
Thirty-six subjects aged older than 60 years, who experienced fall or non-fall, were tested for their functional ability using the TTSST and the Five Times Sit-to-Stand Test (FTSST).
Results:
The data demonstrated excellent reliability (ICCs = 0.943-0.991) and could clearly distinguish the ability of falling and non-falling subjects. In addition, the TTSST showed significant correlation with the FTSST (r = 0.942, p<0.001), and was an excellent fall indicator (sensitivity 88.89%, specificity 100%, AUC = 0.92, 95% CI = 0.81-1.00).
Conclusion:
The TTSST is a valid and reliable method for assessing fall risk factors of community-dwelling elderly. We recommend a TTSST greater than 4.54 seconds as the optimal cut-off score for reliable fall risk prediction for the elderly.

However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
