The integration of Motivational Interviewing (MI) with behavioural and psychological interventions for the treatment of obesity has the potential to improve health-related outcomes of patients in the long-term.

Our objective is to examine the usability of a VR embodiment tool for treating obesity.

Fourteen participants (6 healthy and 8 with morbid obesity) with a desire to make lifestyle changes were randomly assigned to the experimental group (EG) and the control group (CG). Participants from the EG engaged in a virtual self-conversation aiming at understanding their own motivation to make lifestyle changes. Using the body swapping technique, participants were embodied alternately in their own virtual representation and in their counsellor’s body. To better guide this virtual self-conversation, participants were previously trained on MI skills. Participants from the CG were embodied in their own virtual bodies and participated in a “scripted dialogue” with a virtual counsellor who gave them practical recommendations about how to achieve lifestyle changes. A mixed-methods design was used, involving a semi-structured interview examining users´ satisfaction with the virtual experience, as well as self-report questionnaires, including readiness to change habits, body ownership, and system usability.

Participants showed high usability of the platform with higher scores among participants from the EG compared to the CG. Levels of body ownership were satisfactory, with no differences between groups.

Through the integration of MI in the VR context with the patient being properly trained to carry out his/her own motivational self-conversation, we will provide an important advance in the psychological treatments of obesity.

The word motivation derives from the Latin movere, which means to move. In psychiatry, it is an isolated phenomenon found in the substrate of several pathologies, and may be part of an heterogeneous dimensional spectrum. However, there is no unique definition for it, nor a targeted approach. In addictive disorders motivation gains a fundamental role, both as a precipitant of abuse as in its withdrawal.

To review the literature about the concept of motivation and its implications on the psychopathology, especially on addictive disorders.

Narrative review on PubMed/MEDLINE, using the keywords “motivation” AND “psychopatology” AND “addiction”. Articles in English and Portuguese were included.

Three main perspectives were found addressing the concept of motivation in psychopathological terms: psychological, neurobiological and phenomenological. The first describes motivation as the energizing of behaviour in pursuit of a goal. Neurobiology says motivational drive is dependent on the concentration of extrasynaptic dopamine. In phenomenological terms, the concept stands for the web of solicitations that make a certain situation feel in a certain way for the subject. In addictive disorders, learning about what leads to reward, exaggeration in representing those values, and dominance in being guided by those representations lead to alterations on motivation mechanisms.

Motivation is described from different perspectives. Although it is recognized as a fundamental piece in addictive disorders, besides motivational interview model, there are no pharmacological approaches aimed to improving motivation. The recognition of motivation as a concrete psychopathological alteration, and its measure through psychopathological instruments, could optimize the patient’s approach.

Polycystic ovary syndrome(Pcos) disease significantly decreased quality of life for women. Mental health is one of the components affecting the quality of life of these patients that attention to it is necessary to improve their quality of life.

This randomized controlled clinical trial enrolled 60 Infertile Women with PCOS from the city of Sari-Iran in 2020. Participants were assigned to MI and control groups using block randomization. The intervention group received 5 weekly of MI online via WhatsApp. While the control group received only routine care. The psychological Domains score of quality of life in these individuals was measured using the quality of life questionnaire of polycystic ovary syndrome(MPCOSQ) before and after the intervention. Then, the data were entered into the SPSS software, version 25 and were analyzed using descriptive statistics, chi-square test, t-test, and repeated measures analysis of variance.

No significant difference was observed between the two groups before the intervention mean The Psychological Domains scores (p>0.05). After the intervention, mean (SD) of The Psychological Domains score was 34.8 (11.8) in the intervention group and 30.7 (11.6) in the control.No significant Increasing in the mean between the two groups. The effect size(0.35) was calculated.

The results of the study showed that motivational interviewing is effective in improving the quality of life of women with pcos.

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women, which in addition to medical aspects also affects the dimensions of women’s mental health such as stress.

The present study was conducted to determine The effect of online motivational interviewing on stress management in infertile women with PCOS

This randomized controlled clinical trial enrolled 60 Infertile Women with PCOS from the city of Sari-Iran in 2020. Participants were assigned to MI and control groups using block randomization. The intervention group received 5 weekly of MI online via WhatsApp. While the control group received only routine care. Stress management scores in these individuals were measured using health-promoting lifestyle profile II questionnaire (HPLP II) before and after the intervention. Then, the data were entered into the SPSS software, version 25 and were analyzed using descriptive statistics, chi-square test, t-test, and repeated measures analysis of variance.

No significant difference was observed between the two groups before the intervention mean The Stress management scores (p>0.05). After the intervention, mean (SD) of The Psychological Domains score was 22.5 (3.8) in the intervention group and 17.9 (4.1) in the control. The Stress management score was significantly upper in the intervention group compared to the control. (p<0.000). The effect size (1.1) was calculated. NNT (1.6) was calculated.

According to the results and the effect of motivational interviewing is one of the effective methods to manage stress in infertile women with PCOS.
