Objective: One of the most important social factors that have been consistently identified as a predictor of healthy aging is marriage satisfaction. Therefore, the purpose of the present study was to investigate the effect of social support on marital satisfaction with mediating role of emotional loneliness and physical activity. Method: This study was descriptive and correlational based on structural equations. The statistical population consisted of all the elderly in the care centers of Shahrekord and Farsan in 2019, among whom 180 individuals were selected randomly. The participants filled out research instruments including Relationship Assessment scale (Hendrick, 1998), Perceived Social Support scale (Zimet, et al., 1988), Adult’s Social and Emotional Loneliness scale (DiTommasso, et al., 2004), and Leisure-time Activities scale (Godin, 1985). Structural equation modeling (SEM) was used through SPSS (version 23) and AMOS (version 23) software to analyze the data. Findings: The results demonstrated direct effect of social support, emotional loneliness and physical activity on marital satisfaction (p <0.001), and indirect effect of perceived social support on marital satisfaction through emotional loneliness and physical activity (p <.05). Conclusion: The SEM results of the current study support the proposed model which explains the interrelationships between perceived social support, loneliness, physical activity, and marital satisfaction. According to the findings of the present study, it is suggested to pay more attention to the variables of social support, emotional loneliness and physical activity in order to improve the marital relationships of the elderly. The findings of this study can help psychologists and other caretakers create more effective family matter programs for the older generations to enhance their marital satisfaction.

Abstract The aim of the present study was investigating the effectiveness of Transcranial Direct Current Stimulation (tDCS) on neurocognitive performance in people with mild neurocognitive impairment. Using meta-analysis and integrating the research results, this study has specified the extent of the effect of Transcranial Direct Current Stimulation on improvement of neurocognitive function in people with mild neurocognitive impairment. Method: For meta-analyses Magiran, SID, and Irandoc databases were used to search Persian articles and Science direct, Scopus, and PubMed databases were used to find foreign articles, using ‘MCI’, ‘transcranial direct current stimulation’, tDCS, and ‘mild cognitive impairment’ key words for foreign articles and their Persian equivalents for Persian articles. Of the 29 studies, 11 that were methodologically acceptable were meta-analyzed. The research tool was a meta-analysis checklist. Results: The results of meta-analysis indicated publication bias in the studies. Due to the heterogeneity of the studies, a random effect model was used. The effect of Hedges for the impact of Transcranial Direct Current Stimulation on neurocognitive functions in people with mild neurocognitive impairment was 0.26, which is a large effect. Conclusion: This result shows clinicians can choose transcranial direct current stimulation (tDCS) as effective intervention for patients who suffer from mild cognitive impairments. More investigations are necessary to find the cognitive benefits of using transcranial direct current stimulation in elderly people and other cognitive impaired persons.

Objective: This study aimed to investigate the effect of Acceptance and Commitment Therapy (ACT) on goal orientation and feeling of inferiority in individuals with physical-motor disabilities. Methods: This study utilized a quasi-experimental methodology. The statistical population consisted of all students with physical-motor disabilities in Kalaleh County (n = 517). Among them, 30 students were selected as a sample using a convenience sampling method. After explaining the purpose of the research and signing the consent form, they were divided into two groups of 15: the experimental and control groups. The experimental group participated in eight ACT training sessions (one 60-minute session per week), while the control group only answered pretest and posttest. For this purpose, Elliot and McGregor's Achievement Goal Orientations Scale (2001) and Eysenck's Feelings of Inferiority Questionnaire (1976) were used. Results and Conclusions: The findings indicated the effect of ACT-based training on mastery-approach goal orientation and feeling of inferiority in students with physical-motor disabilities. Examining the means showed that the mastery-approach goal orientation increased, and the feeling of inferiority decreased after ACT.
