Social Well-being as a mental health dimension is paid less heed in our society by researchers. The purpose of present study was to investigate psychometric properties of Short-form social well-being Questionnaire of Keyes. To achieve the aim of investigation, 391 and 384 students were selected respectively from Tabriz University and Islamic Azad University of Tabriz by multi-stage cluster sampling. First sample filled Keyes’s Short-Form of Social Well-being Questionnaire. The second filled Newfoundland Memorial Scale of Happiness, General Self-efficacy Questionnaire, interpersonal subscale of SCL-90 and DASS-42 in addition to Keyes’s Social Well-being Questionnaire. Explanatory factor analysis showed that four factor structure of the questionnaire could explain 59.70 percent of total variance. On the other side, confirmatory factor analysis indicated that five-factor model fitted data better than four-factor model. Besides, the findings suggested that social well-being dimensions were positively correlated with happiness and self-efficacy and negatively with difficulties in interpersonal relationship, depression, anxiety and stress. Chronbach’s alpha for factors varied from 0.34 to 0.63 and it was 0.81 for whole questionnaire. Findings corroborated five-factor structure of Short-Form Keyes social wellbeing questionnaire, even so there was not much difference between four and five factor structure, which implied construct validity of this instrument. Moreover, findings showed that concurrent validity and reliability of the questionnaire were acceptable, except for a few subscales.

The present research investigates the effects of neurofeedback on visual memory. This study is an experimental study. For this reason, 30 students in 2 groups of experimental and placebo were investigated. Subjects were assessed with the Wechsler Visual Memory Scale in two stages (pre-test and post-test). Data were analyzed through ANCOVA. The results revealed that after 20 sessions of neurofeedback training, the experimental group exhibited improvement in visual memory. The two groups had significant differences in visual memory. Neurofeedback (NF) refers to an operant conditioning paradigm where participants can learn voluntary control of distinct parameters of their electrical brain activity as measured by the electroencephalogram (EEG). Recent research focused on healthy individuals providing evidence that subjects are able to gain some control over different EEG components and thereby increase performance levels of memory, for example.
