Purpose of Review: Around 80–90% of patients with type 2 diabetes mellitus (T2DM) are overweight or obese, presenting a greater risk for serious health complications and mortality. Thus, weight loss represents a main goal for T2DM management. Although behavioral lifestyle interventions (BLIs) could help promoting weight loss in T2DM patients with overweight or obesity, their effectiveness is still controversial. This systematic review offers an updated and comprehensive picture of BLIs according to Michie’s classification in T2DM patients with overweight or obesity and identifies possible factors (related to both patients and interventions) associated with weight loss. The PRISMA guidelines were followed. The literature search till March 2023 indicated 31 studies involving 42 different BLIs. Recent Findings: Our findings suggest that structured BLIs, characterized by frequent feedback and support, can lead to a clinically meaningful 5% weight loss, regardless of specific behavioral, diet, and physical activity components. Summary: Further research should address methodological issues and heterogeneity of interventions, also considering the effect of pharmacological therapies on weight reduction. Lastly, more attention should be paid to the long-term effectiveness of behavioral lifestyle interventions and to the relationship between weight loss and diabetes.

The aim of this research was to investigate the relationships between creativity, subclinical bipolar disorder symptomatology, and psychological well-being. The study method was of descriptive, correlational type. Significant tests were performed using multivariate regression analysis. Students of the 4th grade of 6 different Italian colleges (N = 329) completed voluntarily the test of divergent feelings (TDF) included in the creative assessment packet (CAP), the Temperament Evaluation of Memphis, Paris, Pisa and San Diego—Autoquestionnaire (TEMPS-A), and the psychological well-being scale (PWB). Significant positive correlations between creativity and bipolar disorder vulnerability, especially hyperthymia, were found. Creativity was, instead, poorly associated to psychological well-being subscales, except autonomy and personal growth. In addition, although multivariate regression showed that creativity was not a significant predictor of almost all the psychological well-being subscales, it did show a significant association with personal growth. On the contrary, bipolar disorder vulnerability, in particular hyperthymia, was found to significantly predict all psychological well-being scales, except personal growth. These results improve knowledge on the mutual association of creativity, psychological well-being, and bipolar vulnerability, giving a theoretical framework in which situate these constructs.

Background: Non-sustainable diets are associated with several environmental and health-related problems. Psychology research is interested in the study of food choice determinants, and several theoretical frameworks have been applied to study mechanisms underlying behavioral change and to develop theory-based interventions. The present systematic review is aimed at reviewing the existing literature on the psychological theoretical frameworks used to study sustainable and/or healthy food choices and their application for the development of interventions promoting such food choices, both in general and clinical populations. Methods: A systematic search of PubMed, PsycInfo, and Scopus was conducted according to PRISMA criteria. Results: Forty-five articles met the inclusion criteria and thirty-five theoretical frameworks emerged, mostly pertaining to social psychology and with the most widely used being the Theory of Planned Behavior. The majority of studies had a cross-sectional design, were conducted in general populations, and focused on healthy food choices. Only a few studies tested theory-based interventions. Internal (i.e., self-efficacy, personal values, and motivation) and external (i.e., peers, family, and social media influence) factors emerged as relevant healthy and sustainable eating determinants. Conclusions: The current review underlines that an integrative perspective combining prompts from different psychology fields is needed in order to identify the psychological factors influencing food choices and to develop psychological interventions for the promotion of more sustainable diets.
