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.

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.

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.

Eating disorders, the most common psychiatric disorders, which are located on a continuum and at the beginning of its healthy eating, disordered eatings in the middle and at the end of continuum anorexia and bulimia. Research purposes: a) Relationship between disordered eatings and behavior of Body checking b) differences in the behavior of men and women of disordered eating and Body checking behavior. Since the factors of eating disorders have major role in prevention programs, has conducted research necessary appears. Method: 140 men and women students of azad university of arsanjan to the random sampling method cluster were selected. The tool includes a Body checking questionnaire (BCQ) eating  attitude test( EAT-26) were. For statistical analysis information correlation cofficient and stepwise regression and independent t-test groups were used. Results: In the total sample (P ≤0/0001) and women with excess disordered eating, Body check more (P ≤0/001). Also, the total sample (P ≤0/0001) and women (P ≤0/001) and men (P ≤0/02),  increasing in signs of dieting was observed with more Body checks. Body checking behavior in women than men more (P ≤0/03) and in men more than women Bulimia and Preoccupation with food (P ≤0/02) was observed.

Background: Having an appropriate appearance in adolescent girls is one of the important traits of adolescence that is affected by various psychological factors and causes the formation of different eating attitudes and behaviors. The aim of this study was to investigate the mediating role of Body checking behaviors associated with alexithymia and parenting behavior to eating attitudes of adolescent girls. Methods: The research method was cross-sectional, descriptivecorrelation based on structural equations. The statistical samples of the study included all female high school students in Torbat-e Heydarieh, Khorasan Razavi in the academic year of 2018-2019 (N=2832); of them, 390 were selected according to the Slovin formula and multi-stage cluster sampling. They filled out alexithymia questionnaires by Bagby et al., and parental rearing methods by Baumrind, and Body checking by Reese et al. The obtained data were analyzed by regression equations using SPSS 23 and Amos 18 software. Results: The findings showed a positive and significant correlation between the variables of alexithymia, permissive, authoritarian parenting behavior and Body checking behaviors with eating attitude; also, there was a significant negative correlation between the variables of assertive and authoritative parenting behavior with eating attitude (P<0. 01). Also, eating attitude based on alexithymia, authoritarian and authoritative parenting behaviors could be directly and indirectly predictable through the mediation of Body checking behaviors, and the research model was approved. It can be concluded that when alexithymia and parental behavior are combined with Body checking behaviors, they have more effects on the intensity of eating attitudes. Conclusion: According to the results, training parenting methods and emotional skills affect the formation of positive attitudes about the Body checking and creating normal eating attitude.

Background: Social anxiety disorder (SAD) is highly prevalent among adolescent girls and significantly interferes with their social and emotional development. It can lead to impaired coping mechanisms and maladaptive behaviors, such as anxiety sensitivity and Body checking. This study aimed to evaluate the efficacy of Emotional Schema Therapy (EST) in mitigating anxiety sensitivity and Body checking behaviors among adolescent girls with SAD.Methods: A quasi-experimental design with a pretest-posttest-two months follow-up assessment was employed. The study participants were 25 adolescent girls aged 15 to 18 years with a diagnosis of SAD in the city of Ramshir, Iran, in 2023. Adolescent girls in the experimental group participated in ten weekly, 90-minute Emotional Schema Therapy sessions. The participants were selected using a multi-stage cluster random sampling technique and completed standardized measures of social phobia, anxiety sensitivity, and Body checking behaviors at the beginning, end, and follow-up of the intervention. To analyze the data, repeated measures analysis of variance (ANOVA) was conducted using SPSS version 27.Results: Participants in the EST group exhibited a significant reduction in anxiety sensitivity (pretest: 53.80±2.85; posttest: 34.67±3.01; follow-up: 35.00±3.35) and Body checking behaviors (pretest: 85.67±3.63; posttest: 50.87±4.24; follow-up: 49.47±3.50) over time (P<0.001). The positive effects of EST on anxiety sensitivity and Body checking behaviors were maintained at follow-up (P<0.001).Conclusions: The findings suggested that EST can be an effective intervention for reducing anxiety sensitivity and Body checking behaviors in adolescent girls with SAD.

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.

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.
