2 to OR = 2.9, in a significant linear trend (F(df1,6) = 60.5; R2 = 0.89; p less then 0.01); whereas the OR for low parental rejection of cannabis use with cannabis use increased in a linear trend (F(df1,6) = 22.8; R2 = 0.75, p less then 0.01) from OR = 1.2 to OR = 2.1. Conclusions Increasing cannabis use of adolescents in Chile requires adjustments of prevention strategies. Prevalence factors identified here constitute potential targets for interventions.Metacognitions, the beliefs held about internal mental processes and the strategies aimed at controlling such processes, are known to play a significant role in the development and maintenance of addictive behaviours. Specifically, lack of cognitive confidence and beliefs about the need to control thoughts have been implicated across addictive behaviours. No research to date, though, has explored the role of metacognitions in cannabis use. Research has also shown that an authoritarian parenting style (where a parent uncompromisingly enforces their own ideas regardless of the will of the child) may be correlated with addictive behaviours. However very limited research has investigated the role of parenting styles in cannabis use. In the current study we aimed to investigate the relative contribution of parenting styles and metacognitions to cannabis use. A sample of 85 participants completed a series of online questionnaires, measuring negative affect, parenting styles, metacognitions and cannabis use. Spearman correlations indicated that cannabis use was positively correlated with each of the metacognitions and both permissive and authoritarian parenting styles. Regression analyses demonstrated that a combination of the physically coercive aspects of the authoritarian parental style and lack of cognitive confidence predicted cannabis use when controlling for negative affect. The implications of the current findings are discussed.Introduction The adoption of adult roles that provide meaning in life is associated with reduced harmful drinking. The current study examined whether this relationship is mediated by increased self-control and reduced value of alcohol. Methods Cross-sectional design. 1043 adults (786 females) ≥18 years old completed an online survey. The outcome variable was scores on the Alcohol Use Disorders Identification Test (AUDIT), predictor variables were presence of and search for meaning in life (Meaning in Life Questionnaire), and mediating variables were trait self-control (Brief Self-Control Scale) and the value of alcohol (Brief Assessment of Alcohol Demand). Results Presence of meaning in life had a significant negative association (B = -0.01, SE = 0.00, 95% CI -0.02 to -0.00, p = .015), whilst search for meaning in life had a significant positive association (B = 0.01, SE = 0.00, 95% CI 0.01 to 0.02, p = .001) with AUDIT scores. The negative association was mediated by increased self-control (B = -0.09, SE = 0.01, 95% CI -0.12 to -0.06) and decreased value of alcohol (B = -0.02, SE = 0.01, 95% CI -0.04 to 0.00), whilst the positive association was mediated by decreased self-control (B = 0.05, SE = 0.01, 95% CI 0.03 to 0.07) and increased value of alcohol (B = 0.02, SE = 0.01, 95% CI 0.00 to 0.04), thereby supporting our hypotheses. Conclusions The relationships between presence and search for meaning in life and harmful drinking are mediated by individual differences in both trait self-control and the value of alcohol.Research focussing on problematic smartphone use has predominantly employed psychometric tests which cannot capture the automatic processes and behaviours associated with problematic use. The present review aimed to identify passive objective measures that have been used or developed to assess problematic smartphone use. A systematic search was conducted using Web of Science, Scopus, PsychInfo and PubMed databases to identify passive objective measures that have been employed to assess problematic smartphone use, resulting in 18 studies meeting the inclusion criteria. Objective data that were monitored predominantly focussed on general screen usage time and checking patterns. Findings demonstrate that passive monitoring can enable smartphone usage patterns to be inferred within a relatively short timeframe and provide ecologically valid data on smartphone behaviour. Challenges and recommendations of employing passive objective measures in smartphone-based research are discussed.Previous research has shown significant and positive associations between social anxiety of parents and their adolescent offspring. The main aim of this study was to investigate this relationship in the social media (SM) context. We tested one hundred and fifty-two couples comprising mothers and their adolescent offspring (12-14 years old) on their levels of problematic Facebook use (PFU) and social anxiety concerning SM use. An actor-partner interdependence model highlighted the positive relationship between the PFU scores of mothers and their offspring on the levels of SM social anxiety in the offspring. We discuss the results in the context of intergenerational transfer of problematic technology use and social anxiety.Background Tobacco-related diseases are a leading cause of death among individuals with severe mental illness (SMI), yet interventions to address tobacco cessation are rare in inpatient settings where persons with SMI are hospitalized. While cigarette smoking rates have declined in the general population, they remain high in persons with SMI. Inpatient settings would be a prime location to intervene on tobacco consumption among persons with SMI. The objective of this review was to examine evidence of smoking cessation interventions in psychiatric inpatient facilities. Method Using narrative overview guidelines, we searched PubMed, PsycINFO, and CINAHL for smoking cessation RCT studies published between 1950 and 2018. Studies included had to have at least started in inpatient psychiatry settings. selleck compound Examples of search terms included smoking cessation in inpatient psychiatry, smoking cessation in inpatient mental health treatment facilities, and smoking cessation and mental health. Results Following the inclusion criteria, eight RCT studies were reviewed.
