Comparison of the Effectiveness of Group Hypnosis Therapy and Group Cognitive Hypnosis Therapy on Eating Attitudes in Women

Background &

Eating habits, food composition and intervals between eating times contribute to the cognitive cause of obesity. Vastrand and his colleagues also found that there is a relationship between nutritional behaviors and obesity in a study titled "Investigating the relationship between eating habits and obesity in Swedish adults" in 2002 (Andersson & Lyttkens, 1999). Therefore, examining the issues and problems of food and nutrition, including determining the pattern of food consumption, can pave the way for determining nutritional policies and plans, eliminating nutritional deficiencies and improving the level of nutrition, and as a result, preventing disease. caused by malnutrition in society. Identifying factors that contribute to eating attitudes has become the focus of research efforts in recent years (Brugnoli, 2016). One of the variables that seems to be effective in improving people's eating attitude is hypnotherapy. Hypnosis is an effective treatment method and a branch of psychological science, which, due to the absence of any chemical drugs and without any side effects, can guarantee the patient's health and cure many mental illnesses and his emotional and emotional disorders. (Bryant et al., 2006). The purpose of this research is to compare the effectiveness of group hypnotherapy and cognitive hypnotherapy on eating attitude in women.

The current research is a part of applied research and quasi-experimental type, pre-test and post-test type with control group with voluntary non-probability sampling method and random assignment in test and control groups, the statistical population of this research Married women will have a body mass score above 25 in Tehran in 1400. The criterion for entering the research sample is a body mass above 25, as well as not participating in other clinical and psychotherapy researches. The statistical sample includes 42 people selected by purposeful sampling and 14 of them are in the control group, 14 in the group hypnotherapy group and 14 in the group hypnotic cognitive therapy group by random sampling. The measurement tools in this research were Gardner et al.'s eating attitude questionnaire (1982), Wilkinson's group hypnotherapy protocol (1981) and Wilhelm et al.'s group hypnosis cognitive therapy protocol (2013). Hypotheses testing and control of the pre-test effect were used to compare the effectiveness of treatments.

Levine's test was used to test the homogeneity of pre-test variances. According to the findings of Table 3, the value of Levin's statistic for pre-test variables of eating attitude is equal to (0.031) and the significance level of the test is greater than 0.05. As a result, it can be said that the variance of the pre-test variables of the two groups is homogeneous.
As can be seen in Table 4, considering that the average difference between the pre-test and the post-test of attitude towards eating in the control group and the hypnotherapy group is (-1.214 and 2.42), respectively, and the mean level is The t-test for the control group and the hypnotherapy group is equal to (0.226 and 0.001) respectively, none of which are significant, as a result, the effect of group hypnotherapy on eating attitude is effective at the error level of 5%.
As can be seen in table 5, considering that the average difference between the pre-test and the post-test of eating attitude in the control group and the hypnotic cognitive therapy group is (-1.214 and 5.714), respectively, and the level of meaning The t-test for the control group and the hypnotic cognitive therapy group is equal to (0.226 and 0.006), respectively, which shows that the effect of hypnotic cognitive therapy on eating attitude is effective at the error level of 1%.
The results of Table 6 show that the F value of the effect of the groups on eating attitude is equal to 3.772 and the significance level of the test is equal to 0.003, which is significant at an error level of less than 1%, that is, the F value of the difference between the groups (Hypnotherapy) group and hypnotic cognitive therapy) on eating attitude is significant at the error level of less than 1%.

In general, the results of this research showed that considering that the average difference between the pre-test and the post-test of eating attitude in the control group and the hypnotherapy group was (-1.214 and 2.42), respectively, and the significance level of the T-test For the control group and the hypnotherapy group, respectively, it is equal to (0.226 and 0.10), none of which are significant. As a result, the effect of group hypnosis therapy on eating attitude is effective at the error level of 5%. The results of this research are in agreement with the results of the research. Madadi and Bozger (2019) are consistent.
Also, the results showed that considering that the average difference between the pre-test and the post-test of attitude towards eating in the control group and the hypnotic cognitive therapy group was (-1.214 and 5.714), respectively, and the significance level of the t-test was for the control group. and hypnotic cognitive therapy group is equal to (0.226 and 0.006) respectively, which shows that the effect of hypnotic cognitive therapy on eating attitude is effective at the error level of 1%. The results of this research are consistent with the results of Taylor and Francis group (2014). In explaining the results, it can be said that if you have had the experience of a slimming diet, you must have suffered from overeating attacks. This happens a few days after the start of the diet. The person has a binge eating attack and will start eating large amounts of food quickly. Also, the results showed that the average difference in attitude towards eating between the hypnotic cognitive therapy group and the hypnotic therapy group is equal to -1.428 and the significance level of the difference is equal to (0.854), which is not significant at the error level of less than 5%, that is, between the two methods. There is no significant difference. However, the average difference in attitude towards eating between the hypnotherapy group and the control group is significant at the 5% error level, and the average difference between the attitude towards eating between the hypnotic cognitive therapy group and the control group is significant at the 5% error level. The results of this research are consistent with the results of Malekzadeh (2020). In explaining the results, it can be said that what causes weight loss diets to fail in a short period of time is lack of self-confidence. These people get tired very quickly and think that the diet has no effect on their weight.
