Purpose: This research was conducted with the aim of determining the effectiveness of treatment focused on emotions on BODY self-concept, BODY inspection behaviors and agitation of patients with anorexia nervosa. Methodology: The research method was semi-experimental with experimental and control groups with a pre-test and post-test design. The statistical population consisted of all patients with anorexia nervosa who referred to the medical centers of Tehran in 1402. The samples were selected using the available sampling method in the number of 30 people and were randomly assigned to the experimental and control groups with the number of 15 people for each group. (2010), BODY Check QUESTIONNAIRE (BCQ) and Disturbance Tolerance QUESTIONNAIRE (DTS) answered. Therapy sessions focused on emotions included 8 therapy sessions that were conducted during 4 weeks, two days a week and each session lasted 60 minutes based on the treatment plan of Greenberg and Geller (2012). In order to analyze the data, multivariate and univariate analysis of covariance tests were used. Findings: The results showed that the scores of BODY self-concept variables in the experimental group increased in the post-test phase compared to the control group, and the scores of BODY CHECKING behaviors and agitation decreased in them. Discussion and conclusion: It can be said that improving BODY self-concept scores and reducing scores in the variables of BODY CHECKING behaviors and agitation in the participants of the experimental group indicated the positive effects of the therapeutic approach focused on emotions.

Nowadays, the fundamental role of having a purpose for life in physical and mental health has been confirmed. According to victor frankl, presence of a purpose in life gives life a meaning and increases resilience against pains and traumas. The importance of the purpose in life construct reveals the need for a reliable and valid tool to measure it. Crumbaugh and Maholick's purpose in life QUESTIONNAIRE is the first and one of the most applied tools for the assessment of life's purposefulness. The aim of this research is to determine the factor structure of purpose in life QUESTIONNAIRE. The QUESTIONNAIRE was administered on 206 students who were selected through random stratified sampling at Ferdowsi University of Mashhad. Exploratory factor analysis showed that there are two factors "comprehension" and "purpose" and this finding were confirmed by confirmatory factor analysis. Altogether results of this research showed factor validity of the purpose in life QUESTIONNAIRE with a two factor pattern

Background: BODY CHECKING and disordered eating behaviors are common problems among adolescents and young people which can be precursors to eating disorders. The research aimed to examine the effectiveness of group narrative therapy in decreasing BODY CHECKING and disordered eating behaviors. Method: This experimental, intervention-control, study was conducted on 920 female 11-16-year-old students selected by multistage random method. They responded to two scales of BODY CHECKING behaviors and disordered eating behaviors. Among 188 female students who gained one standard deviation above the mean score of the group in both scales, 40 students were randomly divided into the experimental and control groups. Then, the members of the experimental group participated in narrative therapy intervention. After the intervention, both scales were distributed among the experimental and control groups. Data were analyzed by the use of descriptive statistics and multivariate covariance method. Results: The results revealed that compared with the control group, narrative therapy significantly reduced BODY CHECKING and disordered eating behaviors in the experimental group (P<0. 01). Conclusion: According to the findings of the present study, the investigation of effectiveness of narrative therapy on these behaviors can provide valuable implications about the mental health of individuals.

The aim of this study was to investigate the relationship between mental health and eating disorders and BODY CHECKING behaviors in girl students. The research method was descriptive-correlational. From all students, a sample of 150 people were randomly selected. Data were collected using Mental Health QUESTIONNAIRE (GHQ), Eating Attitudes QUESTIONNAIRE (Eat26) and BODY Examination Data QUESTIONNAIRE (BCQ) In order to analyze the data, descriptive statistics including mean, standard deviation and variance of inferential statistics including R correlation and multivariate regression were used using SPSS software. The findings showed that the dimensions of mental health can predict eating disorders (disturbed eating) and BODY CHECKING Behaviors. Therefore, it can be concluded that a series of internalized psychological factors, that is, factors in the context of which the "preoccupations" associated with physical transformation are only rationalization and projection of a more fundamental emotional failure cause eating disorders and BODY check.

To investigate a model about BODY image of Iranian’s female students and determining structural relations of physical and psychological factors related to BODY image, 497 female students from Islamic Azad University Zarand Branch randomly selected.After measuring weight, height and calculating BODY mass index of participants, they assessed by BODY image state scale, self- esteem scale of Marsh self-concept test, the appearance schema inventory-revised, personal appearance beliefs test and BODY CHECKING QUESTIONNAIRE. Evaluation of the proposed model with structural equation modeling (SEM) by using of maximum likelihood estimation of AMOS software and calculation of fit indices indicated that, hypothetical model has the goodness of fit with the data. Results showed that, these model direct and indirect effects of physical and cognitive-behavioral factors respectively, .417 and. 33, explain 53% of variation in BODY image. These findings are consistent with the results of other research, modeling in the area of BODY image, and furthermore, helping in better knowing complex biological and psychological structure of BODY image.

Objective This study aimed to investigate the validity and reliability of the Persian version of the “resilience assessment QUESTIONNAIRE” in patients with multiple sclerosis. Materials & Methods The statistical population of the present study included all multiple sclerosis patients living in Tehran City in 2022. Of them, 250 people were selected through available sampling. The participants completed the QUESTIONNAIREs of Gromis et al. resilience and the hospital anxiety and depression scales. The validity of the QUESTIONNAIRE was investigated using the formal, content, construct, and predictor methods. Also, the reliability of the test was checked through the Cronbach α method and retesting. Data analysis was done using SPSS software, version 26. Results The face validity was confirmed by CHECKING the content and solving the appearance problems. The content validity of the QUESTIONNAIRE was confirmed after correcting the questions. The results of exploratory factor analysis showed that the resilience QUESTIONNAIRE includes 5 components: Emotional and cognitive strategies, physical activity and diet, family and friends support, peer support, and spirituality. Also, the Cronbach α values of these components were 0. 88, 0. 79, 0. 62, 0. 76, 0. 50, and 0. 89, respectively. The eigenvalues of these components explained 47. 49% of the variance. There was a significant relationship between the resilience and anxiety/depression QUESTIONNAIRE components. The correlation value between the first and second stages confirmed the retest validity of the resilience QUESTIONNAIRE. Conclusion The Persian version of the “multiple sclerosis resilience” scale is a valid and reliable tool for assessing resilience features in Iranian MS patients, which can be used in policymaking and research studies.

The BODY freedom flutter phenomenon is one of the aeroelastic instabilities that occurs due to the coupling of the aeroelastic bending mode of the wing with the short-period mode in the flight dynamics of the aircraft. By using the aeroservoelastic model and applying closed loop control, this phenomenon can be suppressed in the operating conditions of the aircraft and the velocity of this event can be increased. The simplest model aircraft capable of displaying this instability includes the flexible wing and the planar flight dynamics model. For this purpose, the wing structure is modeled using the Euler-Bernoulli beam and, the theory of minimum variable state is used to model unstable aerodynamics to make the conditions suitable for modeling the system in state space. In the control section, the elevator is used as the control surface and LQR theory with Kalman filter is used to BODY freedom flutter suppression. Finally, the effect of adding a closed loop control to increase the BODY freedom flutter velocity and the limitations of this work are studied.
