The aim of this study was to determinate the validity and reliability of the Persian version of the Brief-BES Test in the elderly. The final version of the Brief-BES Test in the elderly was retranslated and developed based on the viewpoints of experts in elderly studies. 100 elderly men and women were voluntarily selected from Hakim Elahi nursing home in Semnan city. The data were analyzed using descriptive and inferential statistics: confirmatory factor analysis (CFA) and Cronbach’s alpha coefficient to examine factorial and construct validity and internal consistency respectively. Findings indicated good fit of the factor analysis model over the Persian version of the Brief-BES Test in the elderly. In addition, the results of Cronbach’s alpha coefficient demonstrated the acceptable internal consistency of this tool. Proper translation and selecting a heterogeneous sample may have contributed to the good fit of the factor analysis model.

Physical activity has physiological, psychological, and social positive effects. However, the relationship between physical activities and depression of the elderly in the country is unknown. This study was designed to examine the relationship between physical activity and depression. The statistical population consisted of the elderly of Arak city in 2013 and 263 subjects participate in the study. Data were collected with demographic characteristics questionnaire, Geriatric Depression Scale-short form, and Rapid Assessment of Physical Activity (RAPA) and analyzed with Pearson correlation coefficient, linear regression analysis, t test, ANCOVA test with SPSS-16 software. Findings indicated a significant relationship between depression and age, employment, fall history, economic status, physical activity, education, perceived health (P≤0.05). Variables of physical activity, fall history in the past year, economic status, and perceived health predicted depression (R2=0.358; P≤0.05). Mean score of physical activity in the male elderly was significantly higher than their female counterparts, and mean score of physical activity in 60-69-year-old group was significantly higher than their counterparts in 70-79 and ≤ 80-year-old groups (P≤0.05). There were no significant differences between age and gender and mean score of depression. These findings emphasize the importance of the effect of physical activity on depression in the elderly.

Aging is a crucial period in human life and it is a social necessity to pay attention to the issues and needs of this stage of life. The aim of the current study was to study the effect of Body Mass Index (BMI) on reaction time and response time of the active and inactive elderly. The research method was causal-comparative and its statistical population consisted of the elderly from Mahabad city and 60 subjects were voluntarily selected and assigned to two active and inactive groups. After determining the levels of BMI, subjects of each group were divided into three levels of low, medium and high BMI and their reaction time and response time were measured. The results of t test showed that the reaction time (P=0.000) and response time (P=0.000) of the active group were significantly shorter than the inactive group. On the other hand, the results of one-way ANOVA test (to compare the reaction time between active (P=0.623) and inactive (P=0.115) elderly at different levels of BMI) showed no significant difference. For the response time, the results of one-way ANOVA showed no significant difference among active elderly (P=0.576), but there was a statistically significant difference among the inactive elderly (P=0.000). Tukey post hoc test showed that in the inactive group, those subjects with low BMI had significantly shorter response time than the subjects with medium (P=0.001) and high (P=0.000) levels of BMI. The difference between the subjects with medium and high BMI levels (P=0.669) was not significant. The results of this study showed that those individuals with low level of BMI had shorter response time than those with higher level of BMI. Overall, BMI is an effective factor for theelderly's response time and the elderly should desirably maintain their BMI by sufficient physical activity.

Activities of daily life are basic components of life which reflect an important aspect of functional independence in the elderly. The aim of this study was to develop an up to date and culturally appropriate scale to assess activities of daily lives of the Iranian elderly. Research method was descriptive-analytic and the statistical population consisted of elderly men and women (over 60 years old) residing in Arak and Shazand cities in 1391. The sample consisted of two groups including 297 subjects (exploratory factor analysis) and 280 subjects (confirmatory factor analysis) who voluntarily participated in the study. Exploratory and confirmatory factor analysis and principle component analysis with varimax rotation were used for data analysis. All statistical operations were performed with SPSS-16 and LISREL software. Exploratory factor analysis extracted 5 subscales including gross activities (9 items), personal activities (7 items), religious and social activities (8 items), fine activities (4 items), and machine washing (2 items). Confirmatory factor analysis findings confirmed these results as well. These five factors explained 75.90% of total variance (first factor 50.38%, second factor 11.06%, third factor 6.30%, forth factor 4.675%, and fifth factor 3.485%). This instrument was named "the Elderly's Activities of Daily Life Scale (Iran-ADLS)". The scale was filled out twice by 30 subjects (50% women) with 1 to 2 weeks of interval and Pearson correlation coefficient was 0.76 to 0.97 for 1 to 5 subscales and 0.97 for the total score of the scale, indicating a good to excellent test-retest reliability. Also, internal reliability was calculated with Chronbach's alpha (0.96) indicating an excellent internal reliability for this scale. Totally, these results confirmed that "the Elderly's Activities of Daily Life Scale" was a valid and reliable instrument to measure the elderly's ability and disability.

The aim of the present study was to investigate and compare the effects of twokinds of motivational and instructional self–talk on the performance of static anddynamic balance tasks in the elderly. For this purpose, 45 old subjects agedbetween 60 and 70 from Qom province participated in this study. Static balancetask (stand on one leg) and dynamic balance task (SEBT test) were instructed withno self–talk intervention. Then, they were divided into three groups: motivationalself–talk, instructional self–talk and control. One–way analysis of variance andTukey post hoc test were used to analyze the data. The results showed a significantdifference among the groups. The result of Tukey post hoc test showed nosignificant difference in static balance task between instructional and motivationalself–talk (P>0.05). Also, in dynamic balance task, instructional self–talksignificantly improved balance function compared to motivational self–talk(P<0.05). Generally, self–talk as a cognitive strategy was effective in performingbalance tasks and motivational self–talk was preferred in dynamic balance tasks.

The aim of this research was to examine the effect of a training interventionprogram on fall-related motor performance in the male elderly with no regularphysical activities. For this purpose, 39 out of 130 participants in screen test wereselected and assigned to training group (n=20) and control group (n=19). Subjectsaged between 60 and 70 in experimental were 73.68% and in the control group43.75% and subjects aged 71 and above were 26.31% in the experimental groupand 56.25% in the control group. Experimental group participated in a 10-weekintervention program (3 sessions per week and 90 minutes per session). Data werecollected with 30-s seat, sit and reach, one-leg standing (eyes open and closed), upand go, 10-meter walk and 10-meter obstacle walk tests. In this semi-experimentalresearch, Kolmogorov-Smirnov and independent t test was used to analyse motorperformance measures. Results indicated a significant improve in mean scores oflower extremity strength (27.37 rep), flexibility (29.28 cm), static balance with eyesopen (60.94 sec) and closed (19.36 sec), agility and dynamic balance (4.10 sec),10-meter walk (3.35 sec) and 10-meter obstacle walk (4.03 sec) in the experimentalgroup after the 10-week training intervention program (P<0.05). The findingsconfirmed the effect of training interventions (especially strength training) onimproving fall-related motor performance and preventing probable falls in theelderly.
