Psychosocial Factors Predict the Level of Substance Craving of People with Drug Addiction: A Machine Learning Approach

This study aimed to explore which factors had a greater impact on substance craving in people with substance use and the direction of the impact. A total of 895 male substance users completed questionnaires regarding substance craving, psychological security, positive psychological capital, interpersonal trust, alexithymia, impulsivity, parental conflict, aggression behavior, life events, family intimacy, and deviant peers. Calculating the factor importance by gradient boosting method (GBM), found that the psychosocial factors that had a greater impact on substance craving were, in order, life events, aggression behavior, positive psychological capital, interpersonal trust, psychological security, impulsivity, alexithymia, family intimacy, parental conflict, and deviant peers. Correlation analysis showed that life events, positive psychological capital, interpersonal trust, psychological security, and family intimacy negatively predicted substance craving, while aggression behavior, impulsivity, alexithymia, parental conflict, and deviant peers positively predicted substance cravings. These findings have important implications for the prevention and intervention of substance craving behavior among substance users.

Predicting physical and verbal aggression perpetration among teenage boys: an application of the theory of planned behavior

Purpose Aggression has been introduced as one of the serious problems in public health. The purpose of this paper is to evaluate the ability of the extended theory of planned behavior (TPB) to predict the physical and verbal aggression behavior. Design/methodology/approach In this research, 462 teenagers were evaluated through the demographic questionnaire along with the main structures of the TPB as a predictor of behavior. After one month of follow-up, physical and verbal aggression was evaluated. Demographic data were analyzed descriptively by SPSS21 and predictability of the structures for intention and behavior of the physical and verbal aggression was analyzed by AMOS. Findings Mean and standard deviation of participants’ age were 14.70 and 1.12 years, respectively. In this research, 22.5% of the participants did not show physical aggression over the last one month and 20% of them did not show verbal aggression over the last month. Path analysis revealed that the variables of the TPB predicted 61% and 32% of variance of intention and physical aggression behavior, respectively, while these variables could describe 43% and 22% of the variance of intention and verbal aggression behavior, respectively. All of the concepts could be significant predictors of the behaviors. Subjective norms were the best predictor of the intention for physical and verbal aggression. Intention and perceived behavioral control were good predictors of physical and verbal aggression. Research limitations/implications Given the role of subjective norms in intention and also the role of intention and perceived behavioral control of people for aggression, it can be concluded that emphasis on social and psychological education about subjective norms, peer groups and self-control can help reduce this problem. Originality/value A few studies have predicted behavior occurrence in the future. Given the lack of focus on the role of constructs that may bring about future behaviors, the current research was conducted to use the structures of the TPB to predict behavioral intention as well as perpetration of physical and verbal aggressive behaviors, independently.

Perfectionism Classes and Aggression in Adolescents

Some of the components of perfectionism produce a variety of problems, such as interpersonal hypersensitivity and hostility, that may be associated with aggression behavior during adolescence. This study aims to identify classes of adolescents depending on their levels of Perfectionistic Strivings (PS) and Perfectionistic Concerns (PC) as well as to examine whether there are significant differences in the manifestations of the four components of aggression behavior (i.e., anger, hostility, physical aggression, and verbal aggression) between them. A total of 1,074 high school students from various educational centers participated in this study (M = 14.78, SD = 1.84). The Child-Adolescent Perfectionism Scale and the Aggression Questionnaire short form were used. The Latent Class Analysis identified three classes of adolescent perfectionism: (a) Non-Perfectionists (low PS and PC), (b) Maladaptive Perfectionists (high PS and PC), and (c) Adaptive Perfectionists (moderate PS and PC). Results revealed significant differences between classes regarding the different manifestations of aggression. Maladaptive Perfectionists and Adaptive Perfectionists reported, respectively, the highest and lowest levels of aggression behavior. This study assists in educational programs to prevent conflicts related to school violence through emotional adjustment.

PERAN SELF CONTROL TERHADAP PERILAKU AGRESI ORANG TUA KEPADA ANAK

Children are often forced to follow the wishes of their parents, which often leads to aggressive behavior, so that self-control is needed to minimize aggression. This research uses a quantitative approach. The population of this research is all citizens of Makassar who are married and have children. Determination of the sample with the krejcie and Morgan tables, the total sample was 384 respondents. Methods of data collection through a questionnaire with a Likert scale model, and hypothesis testing with simple regression analysis. The results obtained were a significance value of 0.000 <0.05. With a regression coefficient value of - 0.435 and an R Square value of 0.049 or equal to 4.9%. So that the results of this study state that there is a significant negative effect of self control on the aggression behavior of parents towards children in Makassar City. This means that if self-control increases, the aggression behavior of parents towards children will decrease, and vice versa.

Antibiotics increase aggression behavior and aggression-related pheromones and receptors in Drosophila melanogaster

Aggression is a behavior common in most species; it is controlled by internal and external drivers, including hormones, environmental cues, and social interactions, and underlying pathways are understood in a broad range of species. To date, though, effects of gut microbiota on aggression in the context of gut-brain communication and social behavior have not been elucidated. We examine how manipulation of Drosophila melanogaster microbiota affect aggression as well as the pathways that underly the behavior in this species. Flies treated with antibiotics exhibited significantly more aggressive behaviors. Furthermore, they had higher levels of vCA and (Z)-9 Tricosene, pheromones associated with aggression in flies, as well as higher expression of the relevant pheromone receptors and transporters OR67d, OR83b, GR32a, and LUSH. These findings suggest that aggressive behavior is, at least in part, mediated by bacterial species in flies.
