The perevalance of the acute respiratory syndrome coronavirus (COVID-19) has been associated with psychiatric consequences. The aim of this study is to investigate the effectiveness of treatment based on emotional regulation on problems. Cognitive and emotional (memory, mood) and cognitive helplessness (stress, depression, anxiety) in patients who recovered from Covid-19 with Remdesivir treatment in Rafsanjan city.

A semi-experimental research design with a pre-test-post-test design with a control group, the statistical population includes patients with covid-19 in the city of Rafsanjan in 1400 who were treated with Remdesivir. The study sample includes 30 recovered patients who were randomly selected to participate in the study based on their desire and satisfaction and were replaced in two experimental and control groups. Treatment based on emotional regulation was performed in 8 sessions of 1:30 for the experimental group and the control group did not receive any psychological treatment. Both groups answered the depression, anxiety and stress scale (DASS) (1992), the Mood and Feeling Questionnaire (MFQ) (1987) and the memory capacity questionnaire before and after the training process. The data collected on They were analyzed based on SPSS-21 software with descriptive and inferential statistics

The results of the research showed that the treatment based on emotional regulation has a significant effect on improving memory function and mood, as well as depression and anxiety in recovered patients with COVID-19. Treatment based on emotion and stress did not have a significant effect on the recovered patients (P>0.05).

Considering the alarming effect of COVID-19 infection on mental health, it is recommended and emphasized to evaluate the psychopathology of the survivors of COVID-19 in order to diagnose and treatment psychological disorders and problems.

Insomnia is the most common sleep disorder that is associated with cortical hyperexcitability. Potentially transcranial direct current stimulation (tDCS) modifies the cortical state related to insomnia. Therefore, we hypothesized that by using tDCS the intensity of insomnia can be reduced, followed by improvement of the mood symptoms.

This study was an experimental design with a pre-test and post-test with a control group. The statistical sample included 32 females with chronic insomnia that were randomly divided into an experimental group (active stimulation) and a control group (sham stimulation). Transcranial direct current with an intensity of 2 mA was applied for 30 minutes during 12 sessions (three times in the week) in the active stimulation group. In this protocol, anodal stimulation of left Superior temporal gyrus (STG) and cathodal stimulation of right dorsolateral prefrontal cortex (DLPFC) and left secondary motor cortex (SMA). In the control group, sham stimulation was performed for 30 minutes during 12 sessions (three times in the week). The participants were evaluated before and after of the intervention using the Insomnia Severity Index (ISI) and Positive and Negative Affect Scale (PANAS).

The findings of this research showed that the application of transcranial direct current stimulation was effective in reducing the severity of insomnia and improving positive and negative affect (P<0.001, F=19.87). The value of this effect (eta2) in the severity of insomnia, negative mood and positive mood is 0.64, 0.34 and 0.6 respectively.

The results of the present study showed that the implementation of our designed tDCS protocol for the treatment of insomnia, significantly reduced the intensity of insomnia in women with chronic insomnia and improved their mood symptoms.

Attention–Deficit/Hyperactivity Disorder (ADHD) is among the most prevalent childhood conditions. ADHD is characterized by attention deficit, hyperactivity, and impulsivity. ADHD is a behavioral disorder with special features and different effects on mood. Mood critically impacts mental issues and is a major factor in improving individuals’ quality of life. Moods are transient as an emotional state; their fluctuations depend on environmental conditions. Thus, the color of the environment might influence these factors. Colors present various effects on mood states. Individuals with ADHD encounter difficulty in perceiving environmental colors. Besides, exercise positively affects ADHD. Therefore, the current study aimed to compare the effects of perceptual–motor exercises in environments with different colors on mood in children with ADHD.

This was a quasi–experimental study with a pretest–posttest design. Sample size, using G*Power statistical software based on Analysis of Covariance (ANCOVA), to perform the test at a significant level of 5% (α=0.05), with a test power of 80% (β=0.2), large effect size (d=0.5), and the number of the group was measures as 42 subjects. Considering an additional sample in each group due to the possible loss or distortion of the results, 45 subjects were selected to participate in the study. The study participants consisted of 45 children, aged 7–10 years who were selected using a multistage sampling method. Initially, calls were made to schools, health centers, psychology clinics, and social networks, and referrals were screened using The Revised Conners’ Parent Rating Scale (Conners et al., 1998). Accordingly, children who scored above 34 on this questionnaire were assessed by a psychologist and their ADHD diagnosis was confirmed. The research subjects were then randomly divided into 3 groups of 15 individuals as follows: training group in an environment with warm colors (red & orange), a cold–color environment (blue & green), and a hybrid environment (red, orange, blue, & green). All research participants completed the Mood and Feelings Questionnaire (Angold & Costello, 1987) at pretest and posttest stages. The study participants were assigned to the training groups (exercise in an environment with warm, & hybrid colors) and practiced their exercises. The training included 8 weeks of three one–hour weekly sessions of motor–perceptual training with the same training protocol. For data analysis, descriptive (i.e., mean & standard deviation) and inferential (i.e., ANCOVA & Bonferroni posthoc test) were applied in SPSS. A significance level of 0.05 was considered for all tests.

There was a significant difference between the 3 study groups of perceptual–motor training in warm, cold, and mixed color environments concerning negative mood at posttest after removing the pretest effects (p=0.007). Additionally, the mean score of negative mood in the warm–colored environment group was higher than that in the cold–colored environment group (p=0.039). Furthermore, there was a significant difference between the warm–colored environment and mixed environment groups respecting the extent of negative mood (p=0.007); however, there was no significant difference between the cold color environment and the combined environment groups in this regard (p=1.000).

According to the current study findings, children with ADHD, in an environment with warm colors presented further negative mood, indicating the effects of ambient colors on psychological status.

The research aimed to investigate the effectiveness of emotional schema therapy on the mood symptoms and impulsivity of women with bipolar disorder (I, II).

Methods and Materials: 

Present research was semi-experimental study with pretest-posttest design and follow-up with control group that was performed on 30 female patients with bipolar disorder referring to the Farabi hospital in Isfahan in 2016. Participants were selected by available sampling, then they were randomly assigned to experimental (n=15) and control group (n=15). Participants responded to Barratt Impulsiveness Scale (2004), Hamilton Questionnaire and Young Mania Scale in three steps pretest, posttest and follow-up. Experimental group in addition to medication, they received emotional schema therapy in group method during 14, 90-minute sessions while the control group did not received any cognitive intervention. Descriptive statistics methods and analysis of multivariate Covariance and were used for analyzing the data

Findings showed that emotional schema therapy had impact on the dimensions of impulsivity and mood symptoms (depression and mania) of bipolar patients and this effectiveness continued to be sustained in fallow up 3 months later.

Applying emotional schema therapy along with drug therapy can be effective intervention for treatment of mood symptoms and impulsivity in patients with bipolar disorder.

Mindfulness and emotion regulation have important effects on the variables related to mental health in chemical weapons victims. The purpose of this study was to examine the effectiveness of mindfulness-based stress reduction and emotion regulation training on the affect and mood in chemical weapons victims.

This interventional study was conducted with two experimental groups and a control group including 47 male chemical weapons victims with high scores on the General Health Questionnaire in Sardasht city, Iran, randomly selected and then assigned to mindfulness training, emotion regulation training, and control groups. Mindfulness-based stress reduction (MBSR) training was used with experimental group 1, emotion regulation (ER) training was implemented with experimental group 2, and the control group received no training. Data were gathered using the General Health Questionnaire, Positive and Negative Affect and Depression-Happiness scales. Analysis of variance with repeated measure was used for analyzing the data.

The results indicated that mindfulness-based stress reduction and emotion regulation training significantly increased positive affect and mood and decreased negative affect in chemical weapons victims.

The results supported the effectiveness of mindfulness and emotion regulation training on affect and mood in chemical victims. Therefore, attention to the effectiveness of mindfulness and emotion regulation on variables related to mental health is important in chemical weapon victims.

Different daily emotions have different effects on people and each of these emotions play a facilitating or inhibitory role in cognitive and behavioral performances. The aim of this study was investigating the effect of induced mood on male and female students’ behavioral and cognitive performance.

This quasi-experimental study was performed in 2010 in Tabriz. 36 students were selected among the students of Tabriz University by available sampling method. Subjects were divided into three 12-subject groups of positive mood induction, negative mood induction and control. After applying the 3 levels of mood induction, measurement of dependent variables (behavioral and cognitive performance) was done by chronoscope and a researcher-made test (numbers countdown). Data were analyzed by SPSS 16 software using ANOVA method and Tukey’s post-hoc test.

Gender didn’t have a significant effect on behavioral and cognitive performance (p>0.05), but the effect of mood was significant on behavioral and cognitive performance (p<0.05). The interactional effect of gender and mood on behavioral and cognitive performance was not significant (p>0.05).

Induced mood can affect the individual’s performance. Negative mood induction has destructive effects on individuals’ behavioral and cognitive performance and positive mood induction has positive effects. This issue shows the priority of emotion to cognition in struggle of cognition and emotion.

Mood changes and high perceived stress, as the main controversial side effects of oral contraceptive pills (OCPs) may weaken women’s desire for using these pills, thereby, increasing the occurrence of unwanted pregnancies which imposes financial and emotional costs to the families and society. The aim of this study was to investigate the effect of oral contraceptive pill on mood and perceived stress in women referred to family planning clinics. Method and Material: This study with an experimental one group pretest-posttest design was conducted on forty six married women who were recruited with continuous sampling method. They were eligible candidates to use OCP with no previous experiences of hormonal contraceptive use for at least one year. Mood state and perceived stress were measured by the validated instruments of positive affect negative affect scale (PANAS) and perceived stress scale (PSS). The level of mood and perceived stress scores were compared before the intervention and within 3 month follow.

There was no statistically significant differences between positive and negative mood and perceived stress pretest-posttest scores (P=0.133, P=0.756, P= 0.693).

The study findings suggest that consuming OCP(s) has no effects on the women’s mood (with no previous positive history of psychological and mood disorder). In the case of sever mood changes in women using OCP regularly, providing educational and counseling programs regarding stress management as a healthy lifestyle could be beneficial. Furthermore, these strategies would be foundation in preventing unnecessary discontinuation of OCP and subsequent unwanted pregnancies as well as establishing stress management in women as the individuals with key roles in family and community.

Breast cancer with 22.6% is the most common cancer in Iranian women and mastectomy is the treatment of choice in 81% of cases posted for surgery. Mastectomy can evoke feelings of mutilation, altered body image and decreased sexual attractiveness and function leading to mood disorders. In the last decades, final purpose of treatment strategies in breast cancer is creation of a life with good quality. In this regards, concern is rising about the impact of surgical treatments, especially mastectomy on patient`s quality of life. This study was conducted to determine the relationship of mastectomy with mood and quality of life in breast cancer patients.

This descriptive-analytic study was done in 2005.Case group included mastectomy patients referring to the oncology clinics (n=50).The comparison group consisted of mammography candidates referring to women clinics in Imam Reza and Ghaeem Hospitals. Data collected was based on non-probability and purposeful sampling. The information collected included: demographic and medical information, social support questionnaire, POMS survey for measurement of mood. Quality of life was assessed with FPQOLI.

Pearson correlation coefficient showed a significant converse statistical relation between mood and quality of life score in mastectomy women (P<0.001). Independence T test showed that mood and quality of life in mastectomy group were lower than mammography candidate women (P=0.001, P<0.049). The general linear model test showed that group variable had the most effect on women`s mood (P<0.001). Also , mood was the most important factor that predicted level of quality of life in these women (P<0.001).

Lack of attention to psychological and spiritual status of the patients after mastectomy may provide conditions for unstable mood and can finally disrupt their quality of life. But, nurses can identify patients with psychological tensions and introduce them to consultancy centers to prevent mood disorders and promote their quality of life.
