Comparing the Effectiveness of Body Appreciation Training and Self-Healing Training for Food Cravings and Weight Control Self-Efficacy among Overweight Women
Abstract
Food cravings and weight control self-efficacy are psychological issues that can initially and steadily lead to the phenomenon of overweight. The aim of this study was to compare the effectiveness of body appreciation training and self-healing training for food cravings and weight control self-efficacy among overweight women. The method included pretest posttest quasi-experimental design with control group and quarterly follow-up period. Among overweight women referring to control and weight loss centers in Isfahan, 45 were purposed selected and randomly assigned to three groups. The first experimental group participated in 14 weekly 90-minute sessions of body appreciation training and the second experimental group received 14 sessions of 90 minutes and weekly self-healing training. Also, the control group did not receive any intervention during this period. The research instruments were food cravings and weight-bearing self-efficacy questionnaires. The results of repeated measures analysis of variance (ANOVA) showed that in the variables of food cravings and weight control self-efficacy, there was a significant difference between body appreciation training group and self-healing training group with control group. However, there was no significant difference between body appreciation training group and self-healing training group. According to the results, body appreciation training and self-healing training can be used to reduce food cravings and increase self-efficacy related to weight control in overweight women. IntroductionBeing overweight is one of the common disorders that not only creates physical problems but also leads to psychological challenges for the individual (Sasani et al., 2020). A review of the related literature indicates that making efforts to reduce food cravings and weight control self-efficacy can significantly enhance the effectiveness of nutrition and training programs. (Amirizadeh et al., 2016). Given that both of these approaches highlight the role of body appreciation and self-healing in changing the individuals’ attitudes about their self and coping strategies; the present study aimed to compare the effectiveness of body appreciation training and self-healing training for food cravings and weight control self-efficacy among overweight women. Specifically, the current study aimed to find whether there were any meaningful differences between the effect of body appreciation training and self-healing training on food cravings and weight control self-efficacy among overweight women. MethodThis study employed a pretest posttest quasi experimental design with a control group and a three-month follow-up. To this end, the researchers purposefully selected 45 women referring to the wight control centers in Isfahan, Iran in 2021. The participants were randomly assigned to three experimental and control groups. The research instruments included Mol et al.'s food cravings questionnaire (2014) and Clark et al.'s weight-bearing self-efficacy questionnaire (1991). After the participants received the pretest, the first experimental group received in 14 sessions 90-minute sessions of body appreciation training and the second experimental group received 14 sessions of 90 minutes and weekly self-healing training. It should be noted that the control group did not receive any intervention during this period. The participants in the three groups responded to the same questionnaires at the end of the interventions and three months later. To analyze the data, one-way analysis of variance (ANOVA) and chi square tests were used to check for homogeneity, and repeated measures ANOVA and Bonferroni post hoc tests were used to test the research hypotheses. The data were analyzed using SPSS version 24. ResultsTable 1 presents the descriptive statistics related to food cravings and weight control self-efficacy.Table 1.

DiscussionThe purpose of the present study was to compare the effectiveness of body appreciation training and self-healing training for food cravings and weight control self-efficacy among overweight women. It seems that the results of the current study indicated that body appreciation and self-healing training have significant effects on food cravings among overweight women and both led to lower food cravings. The results of this study are in line with the study by Homan and Tilka (2018) who reported similar findings. One possible explanation for the effect of body appreciation might be that this type of training employs positive psychology and identifying weaknesses and strengths to help developing positive attitudes about body, higher body acceptance, and protecting body by preventing unreal expectations.In regards to the effectiveness of self-healing, the findings of the present study were in line with the results of Zarean and Latifi (2021), Irani et al. (2021), Soltani et al. (2020). Moreover, it can be argued that self-healing training, due to its focus on identifying and resolving negative memories and by controlling external and internal triggers, could prevent food cravings.Moreover, the findings indicated that self-healing, similar to body appreciation, positively influenced weight control self-efficacy and led to weight control. It can be mentioned that this training method aimed to teach women to re-evaluate the messages they received about themselves and empower them to reject the negative ones (Bailey et al., 2015). This way, the individuals build a different relationship with their body and enables them to create emotional and cognitive changes; therefore, they have higher self-efficacy in regards to their weight control.The results of the study should be generalized with caution because the sample was limited to women in Isfahan. It is also suggested that future studies use the same training methods in people who aim to have cosmetic surgeries or have negative attitudes about their shape and face in different contexts.
