Psychological Factors Behind Truancy,School Phobia,and School Refusal: A Literature Study

Truancy is a problem that normally leads to treatment interventions within different organizations. Within these organizations different perspectives on the causes and consequences of the above problem can be found. The purpose of this literature study is to map out and describe the current state of research within the fields of school refusal, truancy, and school phobia. The investigation was carried out in the form of a systematic review of the relevant research literature. Research shows that approximately 90% of all young people who refuse to go to school have some form of psychiatric diagnosis.     

Association between substance use disorders and self- and other-directed aggression: An integrated model approach

Our study's objective is to determine whether substance use disorders’ association with aggression differs according to the type of substance and/or the form of aggression, within the same population. We used data from the National Survey on Drug Use and Health across 2008–2014, with a pooled sample of 270,227 adult respondents. We used regression models to estimate the odds ratios for those having alcohol and/or drug use disorder(s) perpetrating (a) each form of aggression compared with no aggression and (b) other-directed compared with self-directed aggression. Alcohol use disorder alone and drug use disorder(s) alone were both associated with significantly increased odds of committing self-directed, other-directed, and combined aggression. Individuals with drug use disorder(s) alone were more likely to commit other-directed than self-directed aggression (adjusted odds ratio = 1.46, 95% CI = 1.04–2.05). Individuals with alcohol use disorder alone were not likely to commit one over the other (adjusted odds ratio = 1.20, 95% CI = 0.90–1.61). In conclusion, the integrated model of aggression based on the stress–diathesis model is a relevant framework to study risk factors for aggression. Further research is needed to identify longitudinal predictors of directionality of aggression.     

Prevalence of Suicide Risk Factors and Suicide‐Related Outcomes in the National Mental Health Study,Colombia

A community survey in 4,426 adults was undertaken as part of the World Mental Health Survey Initiative reporting the prevalence and risk factors for suicide‐related outcomes in Colombia. Lifetime prevalence estimates of suicide ideation, plans, attempts, and risk factors for suicide‐related outcomes were assessed. Retrospective reports of disorders age‐of‐onset were used to study associations between primary mental disorders and first onset of suicide‐related outcomes. Risks of plans and attempts were highest with ideation early age‐of‐onset and within the first year. The highest risk for ideation and attempt among ideators occurred in the 18–29 age group. After first employment (defined as the first paid job accepted by the respondent) and presence of mental disorders constituted risk factors. Impulse‐control disorders were strongest diagnostic predictors.     

Causality and the categorisation of objects and events

The “Tower of London” puzzle was adapted to tablet PCs to be used as a clinical bedside test. “Iso-problems”, a specific class of problems, require identical moves but ball colours are permuted. Thus difficulty is the same even if the appearance is different. We wanted to determine the impact of these as yet little-studied tasks and hypothesised that there may be a learning effect specific to them (the “iso-effect”). We interspersed a set of six iso-problems within one selection of 22 tasks and analysed problem solving by 81 healthy adults (mean age 41.6 years). Participants showed learning across iso-problems (less time, fewer moves, increasingly efficient solutions). This effect was distinct from general learning, as was obvious from comparison with a series of non-isomorphic tasks. However, participants seem not to be aware of solving such problems. This “iso-effect” may be related to implicit memory, a domain that so far has not been assessed using the Tower of London.     

Suicide Clusters: A Review of Risk Factors and Mechanisms

Suicide clusters, although uncommon, cause great concern in the communities in which they occur. We searched the world literature on suicide clusters and describe the risk factors and proposed psychological mechanisms underlying the spatio‐temporal clustering of suicides (point clusters). Potential risk factors include male gender, being an adolescent or young adult, drug or alcohol abuse, and past history of self‐harm. However, the majority of studies lack methodological rigor. Many different psychological mechanisms are described, including contagion, imitation, suggestion, learning, and assortative relating, but supporting empirical evidence is generally lacking. More scientifically rigorous studies are needed to improve understanding of suicide clusters.
