Introduction: Sleep is one of the most important health indicators which demonstrates significant decline with ageing. On the other hand, one of the major problems in the later life is quality of life and sleep. Therefore, the aim of current research is to investigate the efficacy of group physical activity on sleep quality and quality of life in older adults.
Method: The current study is a quasi-experimental study with pre and post- tests and group control. The population of study was older adults who lived in Kahrizak nursing home. 30 older adults selected based on the inclusion criteria. They were randomly assigned to the control (n=15) and experimental groups (n=15). The experimental groups received techniques of group physical activity for ten treatment sessions (60 minutes, two sessions per week). Statistical analysis conducted by analysis of covariance. The research instruments were Pittsburgh Sleep Quality Index (PSQI) and Quality of life (SF-36).
Results: The findings of the covariance’s analysis indicated that there is a significantly difference in sleep quality between older adults in pre and post-test (p= 0.001). Also, it was observed significantly difference between mean’s scores of quality of life among older adults in pre and post-tests (p= 0.001).
Conclusion: Group physical activities have meaningful positive effects on sleep quality and quality of life in older adults. Hence, Physical exercise could be considered by psychologists in nursing homes, as an alternative or complementary approach to existing therapies for sleep problems among older adults.

Introduction: Elderly’s quality of life can be easily threatened by different factors. Therefore, it is crucial to have enough information about elderly’s quality of life and its influencing factors so that actions could be taken to improve their quality of life. Therfore, the aim of the present study was to investigate the relationship between Memory Self-efficacy and Hope with Quality of Life in older adults.
Method: The present research is a Functional and cross-sectional study. For this purpose, the sample of the research is included 120 elderly adults who older than 60, selected with convenience sampling method. The participants completed the Lipad Quality of Life questionnaire, Memory  Self-Efficacy Questionnaire and Snyder Hope Scale. To conduct the necessary descriptive and inferential statistical operations, SPSS (Version 19) was used. Mean, standard deviation and Pearson correlation coefficient were utilized to analyze the data in the descriptive statistics section, and in inferential statistics section, simultaneous multiple regressions were used to predict quality of life.
Results: The results show that quality of life has a positive and meaningful relationship with Memory Self-efficacy (P<0/01, r= 0/29) and hope (P<0/01, r=0/34) in elderly adults. Also, the memory self-efficacy and hope can be explained 13% of variance quality of life in elderly.
Conclusion: Self-efficacy and hope is an important factor for maintaining quality of life in the elderly. Therefore, understanding the memory self-efficacy and hope and strengthen these factors, can be an effective method to enhance the quality of life of elderly people.

Introduction: Instructional self-talk is one of the cognitive processes and strategies that is assumed to be one of the appropriate and applicable interferential methods which can be practiced to improve individuals’ performance. Hence, this study aimed to investigate the effect of instructional self- talk frequency on the older adult’s conduction of motor performance.
Method: This study is of semi-experimental research which is comprised of pre, post and retention tests. 36 older adults from the city of Ahwaz were equally assigned to 3 groups. 1-repetition instructional self-talk, 3-repetition instructional self-talk and no self-talk; respectively distinguished the first, the second and the third group that is considered as the control group. Firstly, the participants took a pre-test. Afterwards they practiced basketball chest pass skill for 2 weeks, 3 sessions a week. After the last practice session, the post test was done and 48 hours following the post test, the retention test was done as well. The criteria to participate in the study were full awareness plus psychological and mental health. The data was analyzed with combined and within group variance analysis at the significance level of (p<0.05).
Results: The findings of the study indicated that the practice of self-talk with 1-repetition in comparison with 3-repetition self-talk and no self-talk, had a positive effect on elders in conducting the chest pass during post and retention tests (p<0.05).
Conclusion: Briefly speaking, less alternated self-talk may improve older adult performance in conducting skills that are attention requiring such as basketball chest pass.
