Comparison of the Effectiveness of Cognitive - Behavioral Therapy with Cognitive - Behavioral Hypnotherapy on the Weight of Obese People

Obesity comes with physical and mental diseases. So, there is a need for effective, accessible and affordable treatments. Due to this example, the effect of cognitive behavioral therapy (CBT) with   cognitive - behavioral hypnotherapy (CBH) on the weight of people with obesity has not been investigated yet

This experimental research was conducted on a sample of 30 people with obesity. The participants were randomly divided into two different cognitive - behavioral and cognitive - behavioral hypnotherapy groups. Simple randomization was done based on the table of random numbers, in which a number was randomly selected and based on the last digit on the right; one of the groups was used to determine the sequence of randomization. It should be noted that if the number on the right was zero or 7 to 9 when choosing a random number, that number would not be considered and a random number would be selected again. This work was continued until all 30 people were assigned to two groups, and concealment was done with the help of sealed envelopes. Both groups were measured in two stages: pre - test and post-test. The measurement tool in this research included body mass index (BMI). Data was analyzed with the help of spss software version 23 with an error of 0.5. Frequency, mean, standard deviation, and T-test analysis were used to describe and analyze the data.

The results showed that there is a significant difference between the cognitive - behavioral hypnotherapy group compared to the cognitive - behavioral group in losing the weight of obese people. The mean and standard deviation of cognitive-behavioral therapy in the pre-test (35.02 ± 4.1) and the post-test (32.5 ± 2.2) as well as the mean and standard deviation of cognitive-behavioral hypnotherapy in the pre-test (35.6 ± 4.30) and the post-test (29.1 ± 2.2) were measured. The Cognitive - behavioral hypnotherapy group, had more than twice weight loss than that of    cognitive - behavioral, and this difference is statistically significant. The difference between the two experimental groups was statistically significant (P < 0.004) and the cognitive - behavioral hypnotherapy intervention had a greater effect on reducing the weight.

It seems that cognitive - behavioral hypnotherapy intervention is more effective than cognitive - behavioral hypnotherapy for weight loss.
