Background & Aims: The relationship between mood and food is complex. Mood can affect the foods we choose to eat. Being stressed about certain life events may lead to uncontrollable eating, whether through binge eating or frequent eating. Certain food choices have been shown to significantly affect a person's mood. Choosing healthy foods such as vegetables and fruits can promote a healthy mood and mental health. Mood and emotion, as well as related therapeutic approaches, should be considered. The relationship between mood and eating behaviors and vice versa is complex and multidimensional, influenced by factors such as hunger, satiety, physiological rewards, age, memory, eating culture, socioeconomic status, and personality traits such as neuroticism or emotional coping styles. Most studies have used reductionist approaches and have focused only on a part of these factors. However, a more complete examination of these relationships is necessary. In addition, assessing the induced mood after the intervention can determine the success of the emotional induction process and help to understand more precisely the psychological mechanisms effective in eating behaviors. In the meantime, paying attention to calorie consumption as an objective behavioral indicator allows examining the experimental results at a more practical level and can strengthen and complement the findings related to eating restriction, so including this variable as a supplementary objective can contribute to the scientific richness of the present study. Obesity is one of the important health problems in women that is closely related to eating restriction and psychological problems such as neuroticism. Inducing positive or negative mood can have a significant impact on eating behaviors and appetite control. In this study, the effect of mood induction on the level of eating restriction in obese women with different levels of neuroticism was investigated to help better understand the psychological factors affecting weight management and mental health in this group.
Methods: The present study was an applied, quasi-experimental study with a pre-test-post-test design and a control group. Out of 2000 obese women who visited the clinic, 348 completed the neuroticism questionnaire, and after meeting the inclusion and exclusion criteria, 60 were purposefully included in the study. The subjects were divided into two groups of women with high and low neuroticism (30 people in each group). Then, each group was randomly divided into three subgroups of negative, positive, and neutral mood induction (10 people in each subgroup). The research instruments were the Dutch Eating Behavior Questionnaire, the Neo Personality Questionnaire, the amount of food consumed in terms of calories, and the Visual Analogue Scale of Mood. Data was analyzed using two-way analysis of covariance in SPSS software version 23. The results showed that inducing positive mood led to a significant increase in eating restraint in women with high neuroticism; such that these women reported a higher level of eating restraint in positive mood conditions than in negative mood conditions.
Results: Findings related to calorie intake also supported the influence of mood and neuroticism interaction on eating behavior. Overall, the findings suggest an important role for the interaction of mood and personality traits in eating behavior and health psychology interventions.
The frequency of subjects by age range showed that most subjects with high neuroticism, 4 people (40%) in the age range of 27 to 35 years in the positive and negative mood induction groups, but in the control group with the same number, most women were in the age range of 18 to 26 years. However, in the low neuroticism group, most women, 4 people (40%) in the positive mood induction groups, were in the age range of 27 to 35 years or between 36 and 45 years; but in the negative mood induction group with the same number, most women were in the age range of 27 to 35 years. Also, in most subjects with high neuroticism, there are 5 people (50%) in the positive mood group with an index between 30 and 33 and in the control group with an index between 34 and 37; but in the negative mood group there are 4 people (40%) with an index between 30 and 33 or 34 to 37. Women with low neuroticism are in the control group with the same number of people (50%) and an index range of 34 to 37 and in the positive mood induction group most women are 4 people (40%) with indices between 30 and 33 or 34 to 37 but in the negative mood induction group most women are in the same number of people with an index of 34 to 37.
Conclusion: The findings of this study indicate that inducing positive mood can effectively increase eating restraint in obese women with high levels of neuroticism, while negative mood does not. These results emphasize the importance of considering mood and psychological characteristics of individuals in designing weight management interventions and indicate that using methods to enhance positive mood can help improve eating behaviors and better weight control in this group. Therefore, combining psychological interventions with mood approaches provides a suitable basis for improving the mental and physical health of obese women.
