Recently, the study of cognitive processes in impulsive individuals has attracted the researchers’ attention. Considering impulsivity as a multidimensional construct, this study was performed to compare cognitive processing speed in 80 female college students who, on the basis of their scores on UPPS Impulsivity Scale (Whiteside & Lynam, 2001), were divided into four groups (n=20 for each) which were dominant in one of the impulsivity components (i.e. Urgency, Lack of Premeditation, Lack of Perseverance, Sensation seeking). Reaction time task was administered on all participants in two positive and negative mood contexts (which was induced by music). Results revealed a significant difference between the functioning of Urgency group and two other groups (Lack of Premeditation & Lack of Perseverance) in negative mood context. There were no significant differences between four groups’ functioning in positive mood context. The role of impulsivity dimensions and mood context on cognitive processing speed was discussed. In general the findings of present research emphasize the multidimensional concept of impulsivity & provide new guides to study lateralized cognitive processes according to personality constructs.

In this study we aimed to investigate whether anodal Transcranial   direct current stimulation (tDCS) of left and right Dorsolatera prefrontal cortex (DLPFC) could affect subjective negative /positive mood in healthy subjects. In a quasi-experimental study, participants (20 female, 20 male) were received three left anodal DLPFC/ Right anodal DLPFC and Sham stimulation (2mA, 20 min)  in a random order independent sessions. The Positive and Negative Affect Schedule (PANAS) was administered for assessing subjective mood, before and after treatment. Friedman Test and Mann-Whitny U were used for analysising data. Results indicated that left anodal tDCS over DLPFC diminish subjective report of negative mood. Moreover, the effects of tDCS on decreasing positive mood in men was greater than women. Active bifrontal tDCS in our population not only was not compatible with previous results in healthy population, but also it was similar to tDCS application in depressed population. Further studies with precise assessment of mood and emotion, and with applying different tDCS montages could generate complementary finding about the role of the DLPFC in subjective mood.

The goal of this study was to examine the role of stress, anxiety and depression and fear of pain on anticipating the movement disability in patients with spinal cord chronic pain. The sample in the research included of 53 persons (41 women, 12 men) with spinal cord chronic pain (back pain) who were approached and referred over the 3 months to a physiotherapy clinic and briefed about the research and voluntarily agreed to participate in the study. Depression Anxiety Stress Scale (DASS), Pain Disability Questionnaire (PDQ), Pain Anxiety Symptom Scale (PASS) and Tampa Scale for Kinesiophobia (TSK) were completed by participants. The obtained data in the research was examined by statistical method of correlation coefficients and multiple regressions. The findings of this study shown that from the subscales of DASS, depression had the highest correlation with movement disability. Also the subscales of PASS, particularly dimension of escape/avoidance had the highest positive and significant correlation with movement disability. The findings showed that depression explained %28 and escape/avoidance explained %36 of the variance of movement disability. Although pain might be considered as a physical health problem primarily, however, psychological components including depression, anxiety, stress and fear of movement could play a crucial role at least in maintenance of pain that needs to be considered in rehabilitation interventions.

The purpose of this research is to evaluate the effectiveness of cognitive behavioral intervention and positive psychotherapy on negative mood among female cancer patients who underwent surgery. The statistical population in this research included all female cancer patients who underwent surgery at Sinai Hospital in Mashhad between April and September 1402. 200 people were purposefully selected and a negative mood questionnaire was distributed among them, and among them were female cancer patients who underwent surgery. (Breast) who received a lower score in the dysfunctional attitude questionnaire, 60 people were selected completely randomly and 20 people were divided into three groups (2 experimental groups and 1 control group). In this research, two standard demographic information questionnaires and Yang's negative mood questionnaire (1990) were used, which are based on the cognitive behavioral intervention protocols of Hoffman et al. (2013) and positive psychology Rashid and Seligman (2011). was executed Finally, the conclusion has been reached that cognitive behavioral intervention (cbt) and positive-oriented psychotherapy have an effect on reducing the negative mood of operated cancer patients; Also, the effectiveness of cognitive behavioral intervention method (CBT) and positive-oriented psychotherapy method on reducing negative mood in cancer patients who underwent surgery is different.
