Introduction
Anxiety disorders are the most common types of mental health disorders worldwide, especially among adolescents [3, 5]. In addition, the prevalence of anxiety disorders in Iranian adolescents, especially girls, is very significant and has been reported as 7-85% [6]. Despite the significant increase in society's awareness of the global importance of anxiety disorders in adolescents, the limited effectiveness, huge costs, and significant side effects of current treatments require the provision of new, effective, cost-effective strategies that do not have alternative or complementary side effects for the prevention and treatment of these disorders. It has doubled in adolescents [2, 7, 8].
Several evidences showing the negative correlation of cardio-respiratory fitness with anxiety symptoms in adults [12-9] have led many researchers to investigate the possible beneficial effects of aerobic training programs on cardio-respiratory fitness and subsequent anxiety symptoms as a A new, effective, cost-effective strategy without potential side effects is promising in the prevention and treatment of anxiety disorders [7, 8, 12-14].
Considering the aforementioned cases and the negative impact of anxiety on personal and social life, on the one hand, the importance of discovering the best method to reduce the negative effects of anxiety, on the other hand, and the lack of research on the subject, the question of the present research is whether eight weeks of aerobic exercise with Does physical display have an effect on teenage girls' anxiety or not?In order to conduct the present practical and semi-experimental research, which was conducted with a pre-test and post-test design and in a parallel random controlled method of 8 weeks. Among the teenage girls who met the criteria for entering the study, working in public and private schools of Shahinshahr city, Isfahan province in the academic year of 1400-1401 in the elementary, first secondary and second secondary courses were selected using easy sampling method [23]. In order to collect data, after the completion of the consent form by the parents of the students, in the pre-test phase, all the subjects were asked the 50-item YAM-5 questionnaire, which contains a 28-item subscale to check the symptoms of the 5 main anxiety disorders and They completed a 22-item subscale to assess the symptoms of 5 different phobias in clinical and non-clinical populations of children and adolescents [24, 25]. Also, the aerobic exercise program with a demonstration approach used in the aerobic exercise-performance group included a series of moderate intensity aerobic exercises in the form of 30, 35, 40, and 45-minute shows derived from the movements of the Afar, Kermanji, and Azeri rituals in accordance with the 10 principles of exercise. [27] was designed. Also, the show program used in the show group included shows of 30, 35, 40 and 45 minutes using creative and improvised show techniques with cultural themes. It should be noted that during the 8-week intervention period of the present study, 30-, 35-, 40-, and 45-minute programs were used in the first 2 weeks, the second 2 weeks, the third 2 weeks, and the fourth 2 weeks of the intervention in 3 sessions per week. it placed.
The training consisted of 8 weeks of aerobic training with basic non-impact and high-impact aerobic movements (combination of low and high contact) and aerobic training with basic non-impact and high-impact aerobic movements (combination of low and high contact) with a demonstration approach; The first stage: warm-up (5 minutes), the second stage: aerobic exercises with basic aerobic movements in order to prepare for the main exercises (10 minutes), The third stage: combined moderate aerobic exercises, rhythmic movements, weight bearing, including movements such as leg press on the floor, simple squats (with bent knees and straight knees) and three-sided squats, dynamic and static squats, planks, lunges, hilaps, side shuffles - rolling Spinning (10 minutes for the first two weeks, 15 minutes for the second two weeks, 20 minutes for the third two weeks, and 25 minutes for the fourth two weeks) and the last step was cooling down and returning to the initial state (5 minutes). The intensity of the aerobic exercises with a dramatic approach is balanced with the rhythm of the music and the main training program includes rhythmic and musical movement patterns that were made by several experts and taught to the subjects. and it was controlled and recorded using a polar clock [31]. Finally, the data were analyzed using analysis of covariance and Bonferroni's post hoc test.
3.Results
The results of the present research showed that eight weeks of interactive aerobic and demonstration exercises have a significant effect on the main anxiety level of teenage girls. Bonferroni's post hoc test was used to investigate the difference between the groups. The results showed that there is a significant difference between the aerobic exercise group and the control group on the one hand, and between the aerobic exercise group with physical display and the control group, but there is no significant difference between the other groups.
In relation to state anxiety, the results showed that eight weeks of interactive aerobic and drama training has no significant effect on the level of phobia of teenage girls.
4.Discussion
The results showed that eight weeks of aerobic exercise with physical display has an effect on the main anxiety of teenage girls. Also, it was found that there is a significant difference between the aerobic exercise group with control on the one hand and between the aerobic exercise group with physical display and the control group, but there is a difference between the other groups. There is no meaning. In the explanation of the present research, it can be said that biologically, mental disorders are caused by the lack of biogenic amines. Biogenic amines are neurochemical substances that facilitate neurotransmission and play an important role in the pathophysiology of mood disorders. Speculations about the neurochemical basis of mental disorders are often around the reduction of serotonin and norepinephrine, researches have shown that aerobic exercise increases the neurotransmitters serotonin and norepinephrine in the body. The determining factor in the speed of serotonin synthesis is the amount of tryptophan in the body. Some researchers have shown that long-term aerobic exercise increases the concentration of free tryptophan in the plasma, which leads to an increase in the synthesis of serotonin and its release into the blood circulation (18). In general, other different physiological and biochemical reasons have been stated for the mechanism of the effect of exercise on mental disorders. Among those reasons, the changes in serum amino acids, which are the precursors of neurotransmitters, which have received more attention than other cases. Recently, increasing the concentration of phenylethylamine in brain cells has been noticed as a substance that has an anti-depressant effect. This substance causes a state of euphoria and vitality due to its structural similarity with amphetamines (16). In order to reduce and treat mental disorders, exercise is used to produce more phenylalanine (20).
In relation to phobia, the results showed that eight weeks of interactive aerobic and dramatic training does not have a significant effect on the level of phobia of teenage girls. In the explanation of the present research, it should be mentioned that considering the above contents and the effect of exercise and physical display on important variables in mental disorders such as serotonin and tryptophan, it is expected that phobia has decreased in the present research, which also happened, but this decrease It was not statistically significant, which may be due to the length of the research period, the intensity of the exercises, the mental conditions of the subjects, etc.
The primary aim of this study was to investigate the variance in academic achievement in two personality types, namely A and B. 100 medical students at internship level from Zahedan University of Medical Sciences were dissociated on the basis of type A and B by type A behavior questioner . In addition, intensity of anxiety and the experience of a recent stressful life events were assessed in each subject. Furthermore, relationship between personality type of subjects (considering intensity of anxiety and the experience of stressful life events) with the means of recent four years averages(as an academic achievement indicator) was investigated. Data analysis by ANOVA in a computerized program • SPSS u indicated:
1) There are no significant differences in academic achievement in two personality types A and B .
2) Type A personality subjects, report significantly greater anxiety than type B personality subjects.
3) The experience of a stressful life events has a significant relationship to lower academic achievement .
On the whole, results of this research, to some extent, are in accordance with other similar research.
Thirty-three Years ago, Gaddum and Picarelli classified the serotonin receptors in the guinea pig ileum into D and M types based on the activity of dibenzyline (D) and morphine (M) to block contractions of intestinal smooth muscle caused by serotonin. The subsequent location of specific ligand binding sites for serotonin in the brain has led to the identification of ten serotonin receptor sub-types in rat brain. The cloning of these receptor sub-types has been of importance in enabling them to be classified as specific protein molecules encoded by specific genes. The problem now arises with regard to the linking of the changes in the cellular activity of the various receptor sub-types with the plethora of behavioural changes that arise as a consequence of the actions of serotonin in the brain.
The present review summarizes the evidence implicating the role of specific serotonin receptor sub-types in sleep, anxiety states, schizophrenia and depression. A summary of the relationship between these receptor sub-types and their possible involvement in the aetiology of these diseases is also given.
This study deals with clinical features of obsessive-compulsive disorder in 100 patients who were referred to selected clinics in Tehran. Using Yale Brown Obsessive-Compulsive Check-list, Millon Clinical Multiaxial Inventory, Beck Depression Inventory and a demographic questionaire, this study represents frequency of different signs and symptoms of o CD, rate of depression, personality disorders comorbidity and demographic characteristics of the sample. The findings show that phenomenological characteristics of OCD in these patients are generally congruent with findings of similar researches in other countries. The exeptions are that the content of symptoms is culture bond, rate of hospitalization is very low and rate of non-pharmacologic treatment is also low. According to these findings, guidelines for designing measurment tools and treatment strategies have been suggested. |
Background : Our purpose in this research was to evaluate the correlation between skill in chess (international chess rating scale) and severity of depression and anxiety and ten cognitive errors in members of Iranian Chess Federation that have international chess rating scale as well as to study the prevalence of depression and anxiety in the sample.
Methods: 96 persons that had an international chess rating scale were sampled with convenient method and took part in this cross sectional study. All samples completed the second version of Beck Depression Inventory, Beck Anxiety Inventory and Cognitive Error Test. Data were analyzed with SPSS software.
Results: There was a significant reverse correlation between chess rating scale and four cognitive errors including over generalization, magnification, jumping to conclusion and must statement. The depression severity decreased by increasing the numbers of hours of game playing in the day. Also there was a reverse significant correlation between chess skill and depression severity, but chess skill had no significant correlation with severity of anxiety. The prevalence of mild moderate depression was 16.7%. There was no case with severe depression. The prevalence of mild and moderate anxiety was 27.1% and severe anxiety was 5.2%.
Conclusion: We conclude that this significant reverse correlation between chess rating scales and depression severity is mediated by decrease of cognitive errors and the number of the hours of game playing in the day, which is in accordance with Beck's Cognitive Theory and Behavioral Activation Theory.
Background: Given the increase in prevalence of Coronary
Artery Bypass Graft (CABG) surgery and the significant role of psychological
factors in prognosis and relapse of cardiac disease, the present study is
designed to determine the relationship between psychological factors or
impotency and quality of life of male patients following CABG.
Methods: In this descriptive- analytical study 160
male patients were randomly selected four weeks after heart surgery and were
administered DASS-21, IIEF-5 and SF-36 to assess anxiety, depression and stress,
impotency and quality of life, respectively. Regression analyses (One-way
ANOVA) and Chi-square were performed to analyze the data.
Results: Findings showed that the average age of
patients was 60 (±10) years. Among psychological variables the average score
for depression was significantly related to the average scores of quality of
life (p=0.02). Furthermore, 62.4% of patients had some degrees of depression
86.7% had some degrees of stress and 47.3% had anxiety to some degree. Also,
85.5% of patients displayed mild to severe levels of erectile dysfunction which
were significantly correlated with scores in anxiety (p=0.03) and depression
(p=0.001). Finally, diabetic patients had higher scores in depression and
stress compared to non diabetic patients.
Conclusion: The findings
are discussed in the context of proposing interventional strategies for
improving psychological conditions of CABG patients.
Background: Nulliparous women
often are extremely anxious because of fear of labor pain and this anxiety will
decrease their chances of normal vaginal delivery. The aim of this study was to
investigate the effects of chewing sugar-free gum on labor anxiety in
nulliparous women.
Methods: This study was a randomized
clinical trial and performed on 66 nulliparous pregnant women with spontaneous
labor pains in Ahvaz Razi hospital in 2011. Samples were randomized to case
group (n=34) and control group (n=32) based on the inclusion and exclusion
criteria. Maternal anxiety was measured at baseline using Spielberger anxiety
scale. Then an Orbit sugar-free chewing gum was given to case group. The women
in the control group did not receive any intervention. After 30 minutes of
chewing gum anxiety was measured in all subjects again. Also labor stages duration,
type of birth and the need for oxytocin in both groups were recorded. Data were
analyzed using descriptive statistics, t-tests and chi-square in SPSS version
15. A p-value less than 0.05 was considered statistically significant.
Results: Findings
of this study showed that after 30 minutes of chewing gum, mean and standard
deviation of active phase anxiety of women in case group (42.85±5.46) was significantly lower than
control group (49.82±7.68). In the case group, active
phase duration were significantly less than control group (177±89.03 min in
case group VS. 229.03±59.68 min in control group p=0.001). Also second stage of labor
duration in the case group (43.91±10.96) was less than control group (52.65±18.27) with p-value of 0.021. Type of
delivery and the need for oxytocin were not significantly different between the
two groups.
Conclusions: Based on the findings of this
study it seems that chewing a gum can be used to reduce anxiety of labor as a
non-invasive and effective method.
Background: Heart
disease is the most common cause of death that has increased in developing
countries. Coronary Artery Bypass Graft (CABG)
surgery is one of the treatment methods in these patients that have been used
widely over the past decade. This study was performed with aim of resolving the issues related to
lack of patients' familiarity with anesthesia and surgery and inattention to
their training needs due to anxiety and dysfunction of hemodynamic
statue.
Methods: In this
semi-experimental study, 124 patients who were candidates for CABG were
randomly assigned to either the test or control groups. Patients' anxiety was
evaluated by Amsterdam questioner and checklist was used for recording
hemodynamic variables. The collected data were analyzed using the paired,
independent t test and ANOVA in the SPSS.
Results: There were no significant differences between
demographic variables in two groups. There were no significant differences
between patients' anxiety, hemodynamic status, educational needs at admission
time and before surgery in control group but in the intervention group, anxiety
of patients decreased after the intervention (p<0.001). Hemodynamic
variables in two groups changed before surgery (p<0.05). There was
significant relationship between gender, level of education and patients'
anxiety (p<0.05).
Conclusions: Considering the
benefits of education on patient’s anxiety and hemodynamic status, more attention
should be given by health care providers to patient education.
Background: Depression has often been considered as a major cause
of human health threats in the world. The goal of the current study was to predict postpartum
depression among women attended health care centers in Shiraz based on parental
bonding, history of anxiety, and depression .
Methods: In this regard, 120 women with postpartum depression
were selected among the women who had delivered in hospitals of Shiraz using
convenience sampling method. The tools were Parental Bonding Instrument
(PBI), Postnatal Depression Scale (Edinburgh), and the checklist of anxiety and
depression using diagnostic criteria of anxiety and mood disorders (DSM- IV-IR). Data
were analyzed using multiple regression analysis with stepwise method through
SPSS v.16.
Findings: The linear regression model showed that
extraordinary protective factors of caring father (p<0.001) and mother
(p<0.001) have significant effect on depression. Considering the calculated
coefficient determinant (R2=0.44), the extraordinary protective
factors of caring father and mother, predicted 44% of postpartum depression. It
means that 44% of changes by postpartum depression in caused by the
extraordinary protective factors of caring father and mother.
Background: The present study was carried out to examine the effectiveness of Mindfulness and Acceptance-Based Group Therapy on decreasing fear of negative evaluation in patients with social anxiety among female students.
Methods: In the first stage, Social Phobia Inventory (SPIN) was administrated to 402 female student of Shahed University, In the second stage 24 socially anxious student screened by SPIN and (Structured Clinical Interview for DSM-I) (SCID-I) were randomly assigned to experimental group (13 subjects) and control group (11subjects). Then Mindfulness and Acceptance-Based Group Therapy administered to the experimental group, while control group didn`t attend in any treatment session. All participants completed measure of brief version of the Fear of Negative Evaluation Scale at pretreatment and post treatment and three month follow up.
Results: The result of Mann Whitney test revealed significant reduction in fear of negative evaluation in experimental group than control group (p<0.001) which remained stable three month after the end of treatment.
Conclusion: In sum, Mindfulness and Acceptance-Based Group Therapy can improve fear of negative evaluation among a sample of Iranian female students. Therefore a ground has been provided to apply this approach preliminary in psychological centers on patients with social anxiety disorder.
Background: Many studies have showed that electromagnetic field decrease anxiety. In this study the objectives: effect of Electromagnet Fields in Low Frequency in Induced Anxiety by formalin. Methods: 32 male mice with weight (30 grams) were classified in 4 groups (n=8), and received Histamine (5mg/kg IP injection) 3classes of every group exposed to electromagnetic field (emfs) with25, 50, 75 HZ& frequency with intense250µT for10 min before injection. One group was chosen as control. Anxiety signs in 3groups (expose) compared with control group.
Background: Cancer is primarily a genetic disease and Myeloid dysplasia refers to a group of syndromes thathave a close relationship with each other and through the proliferation of arbitrary one or more types of bone marrow cells, are identified. One of the most prevalent psychiatric symptoms in patients with cancer, transplantand anxiety, is death anxiety. This type of anxiety can be viewed as one of the important psychological diagnosis in patients with suspected cancer. This study aimed to investigate the effect of hypnosis ondeath anxiety in patients with acute myeloid leukemia treated with chemotherapy.
Methods: The research method was quasi-experimental with pre-test and post-test in experimental and control groups. Twenty-fourpatients with acute myeloid leukemia on chemotherapy with medical records and flow cytometry test were selected and randomly divided in experimental (n = 13) and control group (13 case). Death Anxiety Inventory Collet-Lesterinwas used to collect data from two group before and after trial. Six sessions of hypnotherapywas conducted for the experimental group in six weeks. SPSS₂₂ was used for statistical analysis of data
Results: The results showed that hypnotherapysignificantly reduces the anxiety duedeath, dead people, see people dying and death anxiety in general, which has been statistically significant (p<0.001).
Conclusion: As a result, it can be said that hypnosis is an effective intervention on the anxiety of death in patients with acute myeloid leukemia underchemotherapy and can be used as a non-invasive method
Background: In this research effectiveness of mindfulness based cognitive therapy (MBCT) on depression, anxiety and somatic symptoms in asthma patients was studied. Asthma is a psychosomatic disorder that depression and anxiety were considered as a trigger or exacerbation factor for it.
Methods: According to this matter MBCT was used for reducing depression and anxiety and somatic symptoms in asthma patients. For this purpose 26 female patients that were under medical treatment for 1 year at least in Isfahan were selected and assigned in two groups randomly (experimental group and control group). Two groups were tested (pre-test) by Beck Depression Inventory (BDI_II), Beck Anxiety Inventory (BAI) and Asthma Quality of Life Questionnaire (AQLQ). Experimental group received MBCT intervention for 8 sessions weekly for two hours and control group was registered in waiting list. After finishing the therapy the two groups were tested again (post-test). Data was analyzed by ANCOVA in spss21 program.
Results: Results show that after MBCT intervention significantly depression, anxiety and somatic symptoms scores decreased in experimental group in comparison with control group (p<0/05).
Conclusion: So it shows that MBCT can reduce level of anxiety and depression in asthma patient and then reduces somatic symptom in this patients.
