The objective of the current research study was to investigate the relationship between empathy and self-compassion and altruism in mothers of children with Autism Spectrum Disorder and intellectual and developmental disabilities. Method: by convenience sampling, 161 participants were selected. The short form self-compassion, empathy and altruism inventories were implemented. Results: The Pearson’s correlation coefficient and multiple regression analysis revealed that there was a direct relationship between empath, self-compassion and altruism. Conclusion: Empathy is a complex capability which enables individuals to understand the emotional states of others, and results in compassionate behaviour. Empathy requires cognitive, emotional, behavioural, and moral capacities to understand and respond to others' suffering. Compassion is a proper response to the perception of others’ suffering. In addition, compassion cannot exist without empathy; they are part of the same perception and response continuum which moves human beings from observation to action. It seems that maternal care, together with the hope that a child with intellectual and developmental disabilities lives independently, provides the necessary grounds for empathy, self-compassion and altruism.

The current research was conducted to determine the mediating role of negative Affection toward self- forgiveness, and procrastination in male students of the University of Tabriz. Therefore, 361 male students between 18-22 were selected by a random cluster sampling method from three groups of Technical and engineering, basic science and human science faculties. The General Procrastination, Decisional Procrastination, Positive and Negative Affect, and Heartland Forgiveness inventories were used to gather the data. The theoretical model was tested within a structural equation- modelling framework to identify both direct and indirect effects. The results indicate an overall fit model. Although the direct effects of self-forgiveness on decisional and general procrastination behaviours were not significant, thus, an indirect impact of self-forgiveness on the decisional and general procrastination behaviours were fully mediated by negative affection. Also, the effect of self-forgiveness on negative affect and academic procrastination, the training was essential for students.

The effect of nanoclay contents on the physical and mechanical properties of bagasse flour/ reprocessed high density polyethylene (rHDPE)/ nanoclay composites was investigated. The bagasse flour content was constant at 50%, the maleic anhydride content was constant at 3%, and the nanoclay (Cloisite 30B) content was set at three different levels: 0%, 2%, and 4%. The materials were mixed in a co-rotating twin-screw extruder; afterwards, the specimens were fabricated using an injection molding method. The water absorption and mechanical properties, such as flexural and tensile strength, flexural and tensile modulus, and notched impact strength, were measured. The nanoclay dispersion was examined by X-ray diffraction. The results indicated that tensile and flexural modulus increased with an increase in nanoclay content. Also By increasing the nanoclay content at 2 wt.%, the tensile and flexural strengths of the composite were increased. However, the addition of 4 wt.% nanoclay resulted in reductions of these properties. Water absorption decreased with increasing nanoclay content. The structural examination of the bagasse polymer composite with X-ray diffraction showed that the nanoclay was distributed as an intercalated structure in the polymer matrix, and the d-spacing of layers decreased with increasing nanoclay content. Scanning electron microscopy (SEM) showed that 2% nanoclay samples with lower and more uniform pores compared at 4% nanoclay samples, respectively.

Abstract Introduction: The association between psychological well-being and physical and mental health has been shown in the literature. Psychological well-being is a multifaceted concept. The World Health Organization-5 Well-Being Index (WHO-5) is a 5-item instrument used to screen for depression. However, the validity of the WHO-5 has not been investigated in Iranian psychiatric or psychological settings. Objective: To investigate the validation of the Farsi version of the WHO-5 in a sample of Iranian psychiatric outpatients. Methods: A cross-sectional study was conducted with a convenience sample of 116 Iranian volunteer psychiatric outpatients selected from the psychiatric and psychological clinics at the School of Behavioral Sciences and Mental Health - Tehran Institute of Psychiatry, Iran University of Medical Sciences. Patients completed the WHO-5, the Patient Health Questionnaire-9 (PHQ-9), the Patient Health Questionnaire-15 (PHQ-15), and the short form of the Beck Depression Inventory-13 (BDI-13). Results: The mean score of the WHO-5 was 8.95 (standard deviation [SD] = 5.49). Cronbach's α for the WHO-5 was 0.91. The WHO-5 negatively correlated with PHQ-9 (-0.358), PHQ-15 (-0.328), and BDI-13 (-0.475), indicating good validity. Factor analysis of the WHO-5 items identified one factor labeled psychological well-being. Conclusions: The WHO-5 has a single dimensional structure and acceptable psychometric parameters. The results of this study suggest that WHO-5 can be used in a clinical context in Iran.
