Problematic smartphone use and affective temperaments among Lebanese young adults: scale validation and mediating role of self-esteem.

BACKGROUND: Adults all over the world face serious issues from problematic smartphone use (PSU). It influences them negatively on a cognitive, behavioral, and emotional level, as well as on their tendencies and well-being. In Lebanon, the prevalence of PSU was shown to be 20.2% within the adult population, specifically with young adults (18-34 years old). This study investigates the validity and reliability of the Smartphone Addiction Scale (SAS) Arabic version. In addition, this study evaluates the association between PSU and affective temperaments and the mediating role of self-esteem in this association. METHOD: A cross-sectional study was carried out between August and September 2020, using a sample of community-dwelling participants aged 18 to 29 years. The Smartphone Addiction Scale-Short Version was used to evaluate smartphone addiction among adolescents and adults. The five different temperaments of the patients were assessed by using the Affective temperament Scale (TEMPS-A). The Rosenberg Self-Esteem Scale was used to evaluate self-esteem. RESULTS: 461 participants were included in this study. All items of the SAS were extracted and yielded a one-factor solution with Eigenvalues > 1 (variance explained = 49.96%; αCronbach = 0.886). The confirmatory analysis results consolidated those obtained from the factor analysis. Higher depressive temperament (B = 0.46) was significantly associated with more smartphone addiction, whereas higher self-esteem (B = - 0.28) was significantly associated with less smartphone addiction. Self-esteem was found to mediate the association between depressive and hyperthymic temperaments with smartphone addiction. CONCLUSION: This study added a better understanding of the high smartphone addiction rate among adults in Lebanon. It confirms the association between affective temperaments and PSU through the mediating effect of self-esteem on Lebanese adults.

Effects of date seeds administration on anxiety and depressive symptoms in streptozotocin-induced diabetic rats: biochemical and behavioral evidences.

OBJECTIVES: Several epidemiological data indicate that chronic hyperglycemia is associated with behavioral changes such as anxiety and depressive symptoms. Date seeds, one of the most potent products with potential antioxidant activities and possess many benefits against hyperglycemia and its complication. The aim of the current study was to explore the potential effect of date seeds extract on biochemical and behavioral changes (anxiety and depression) in streptozotocin (STZ)-diabetic rats. METHODS: Rats were divided into four groups as follows: normal control, diabetic control, diabetic treated with the lyophilized aqueous extract of the date seed (2,000 mg/kg) (LAE-DS) and diabetics treated with insulin (4 UI/day). Experimental diabetes was induced by a single intraperitoneal injection of STZ (60 mg/kg). After 24 days treatment period, anxiety and depressive behaviors were evaluated using four behavioral tests. After sacrifice, blood samples were collected to evaluate lipid parameters. In addition, rat organs (kidney, liver and brain) were dissected out in order to estimate lipid peroxidation levels as oxidative stress marker. RESULTS: Oral administration of the lyophilized aqueous extract of date seeds and insulin injection for 30 days significantly decreased blood glucose levels in STZ-diabetic rats and protected them against undesirable changes in lipid parameters, including cholesterol, triglycerides, LDL cholesterol, VLDL cholesterol and atherosclerosis index. Compared to untreated diabetic rat, a significant decrease in lipid peroxidation levels in kidney, liver and brain (Hippocampus and prefrontal cortex) were observed after treatment with insulin or LAE-DS in diabetic rats. Furthermore, insulin and LAE-DS administration prevented anxiety-related behaviors in STZ-diabetic rats. CONCLUSIONS: Therefore, it would be possible to combine this extract with insulin and use it as an antioxidant supplement for type 1 diabetic patients.
