Prevalence,dynamic risk factors and the efficacy of primary interventions for adolescent dating violence: An international review

Adolescent dating violence is a pressing international issue: yet, there have been few attempts to collate the international evidence regarding this phenomenon. This article reviews contemporary evidence from Europe and North America on prevalence, dynamic risk factors, and the efficacy of intervention programs for adolescent dating violence. Prevalence findings suggest that victimization rates are comparable across Europe and North America. Although individual studies report differing prevalences, the overall hierarchy of violence types – in which psychological/emotional violence is most and sexual violence least prevalent – is consistent across almost all investigations. Four dynamic risk factors for perpetration are identified: peer influence, substance use, psychological adjustment and competencies, and attitudes towards violence. Peer influences and attitudes towards violence appear to be the most extensively evidenced factors in the literature. Nine existing intervention programs are identified, all located within North America. Intervention results are mixed, with some evaluations reporting significant long-term benefits while others report positive intervention effects dissipate throughout follow-up. Tentative analysis suggests that programs focused on behavioral change may elicit sustainable effects more readily. However, this is difficult to ascertain with no data on program repetitions and variations across intervention pedagogy and sample. Concerns with existing research and interventions and possible future directions are discussed.     

Well-being and Need for Support of Adolescents with a Chronically Ill Family Member

This study investigates whether there are differences in the well-being, need for help and use of support services between adolescents with and without a chronically ill or disabled family member. It also examines the role played by the type of illness, the relationship to the family member and the nature and intensity of the help provided by the adolescent. A Dutch sample of 1581 adolescents (average age 14.6?years) completed a questionnaire in 2010 about mental health problems, pro-social behavior, need for and use of support and the illness of family members and any care tasks performed by the respondent. Young people with a sick family member had more mental health problems than their counterparts without a chronically ill family member. They also reported a greater need for and use of help and support. Performing domestic tasks was found to be a predictor for overall mental health problems. The intensity of the help given was related to the need for help by the adolescent. It is concluded that growing up with a chronically ill family member and spending a lot time performing (domestic) tasks are risk factors for adolescent mental health problems and adolescents’ need for help. Special attention is warranted for those who need support but who do not translate that need into reality by seeking help.     

How shared preferences in music create bonds between people: values as the missing link

How can shared music preferences create social bonds between people? A process model is developed in which music preferences as value-expressive attitudes create social bonds via conveyed value similarity. The musical bonding model links two research streams: (a) music preferences as indicators of similarity in value orientations and (b) similarity in value orientations leading to social attraction. Two laboratory experiments and one dyadic field study demonstrated that music can create interpersonal bonds between young people because music preferences can be cues for similar or dissimilar value orientations, with similarity in values then contributing to social attraction. One study tested and ruled out an alternative explanation (via personality similarity), illuminating the differential impact of perceived value similarity versus personality similarity on social attraction. Value similarity is the missing link in explaining the musical bonding phenomenon, which seems to hold for Western and non-Western samples and in experimental and natural settings.     

A routine perspective on implementing reflective career conversations in education

ABSTRACT

Reflective career conversations are a necessary instrument in the career guidance of students in vocational education. These conversations help students to learn from their (work) experiences and gain a better understanding of their motives on the labour market. Research shows that in a society in which change seems to become the only constant factor, knowing one’s own motives in work is important. However, the introduction and implementation of reflective career conversations in Dutch vocational education is problematic. In this article, we introduce the concept of ‘routines’ to better understand the nature of these problems. The concept ‘routine’ allows us to understand in much more detail what is required to induce the necessary behavioural changes that are required from teachers, students and management. Recognition of the complexity of this process and the willingness to invest are necessary prerequisites to prevent reflective career conversations from becoming the next ‘trick’ or ‘trendy innovation’.     

Parental illness intrusiveness and youth glycaemic control in type 1 diabetes: intergenerational associations and processes

Objective: This study examined associations between the functioning of youth with type 1 diabetes and their parents, including parenting dimensions as intervening mechanisms. The study adds to the existing literature by focusing on (1) the concept of parental illness intrusiveness; (2) the (understudied) periods of adolescence and emerging adulthood; and (3) maternal and paternal functioning. Design: Questionnaires were completed by 317 patient-mother dyads and 277 patient-father dyads. All patients (aged 14–25) had type 1 diabetes. The hypothesised model was compared to an alternative model using structural equation modelling. Main Outcome Measures: Youth reported on depressive symptoms and treatment adherence; Physicians provided HbA_1c-values. Parents reported on illness intrusiveness, depressive symptoms, and their child’s treatment adherence. Patients and parents reported on psychological control and overprotection. Results: The hypothesised path model had a good fit to the data. Parental illness intrusiveness was positively associated with depressive symptoms and both were positively related to overprotection and psychological control. Psychological control was positively related to patients’ depressive symptoms and negatively to treatment adherence. Poorer treatment adherence was associated with worse HbA_1c-values. Conclusion: These findings underscore the relevance of parental illness intrusiveness and emphasise the importance of mothers’ and fathers’ roles throughout adolescence and emerging adulthood.     

Global precedence as a postperceptual effect: An analysis of speed-accuracy tradeoff functions

Two experiments examined the speed-accuracy tradeoff for stimuli used by Martin (1979), some of which have a Stroop-like conflict between the relevant (to-be-judged) and the irrelevant aspect. Speed of transmitting information about a local aspect was significantly reduced when the irrelevant global aspect conflicted with the relevant local aspect, while speed of transmitting information about the global aspect was not affected when the irrelevant local aspect conflicted with the relevant global aspect. This result, when extrapolated to the accuracy level of an ordinary reaction-time task, fitted very well the reaction-time predictions of the global precedence model proposed by Navon (1977). However, other results were incongruent with the fundamental assumption of that model: that global features are accumulated with temporal priority over local features. The finding that, independently of speed, information transmission of the global aspect started later when the irrelevant local aspect was conflicting, corroborates Miller’s (1981a) conclusion that global and local features are available with a similar time course. Global precedence is therefore a postperceptual effect; absence of interaction with S-R compatibility suggested that it operated before the response selection stage. The term global dominance may be preferred, because it avoids the implication of prior availability for the global aspect. Furthermore, the possibility of whether Stroop conflict should be considered a necessary condition for global dominance is discussed.     

Car following from the driver’s perspective

In this commentary, it is argued that the car following models discussed in Brackstone, M., and McDonald, M. (Transportation Research – Part F (2000), pp. 181–196) ignore one or more of the following issues that characterize to observed driver behavior. These include: (i) car following is only one of many tasks that drivers perform simultaneously and receives therefore only intermittent attention and control (task scheduling/attention management), (ii) drivers are satisfied with a range of conditions that extend beyond the boundaries imposed by perceptual and control limitation (satisficing instead of optimal performance evaluation), and (iii) in each driving task drivers use a set of highly informative perceptual variables to guide decision making and control (perceptual rather than Newtonian input). To elucidate these issues, a general driver modeling framework is presented in which the car-following task is highlighted (Boer, E. R., & Hoedemaeker, M. (1998). In Proceedings of the XVIIth European Annual Conference on Human Decision making and Manual Control December 14–16. France: Valenciennes; Boer, E. R., Hildreth, E. C., & Goodrich, M. A. (1998).

Ethical Issues in Neurografting of Human Embryonic Cells

During the last decade neurotransplantation has developed into a technique with the possible potential to repair damaged or degenerating human brain. Effective neurotransplantation has so far been based on the use of fetal brain tissue derived from aborted embryos or fetuses. The ethical issues related to this new therapeutic approach therefore not only concern the possible adverse side effects for a neural graft-receiving patient, but also the relationship between the requirements for fetal tissue and the decision-making process for induced abortion. Although for decades human embryos and fetuses have been the subject of biomedical studies, and, in principle, their use has therefore not been seen as ethically objectionable, the above points made it necessary to reconsider the moral issues. The present paper points out several of these issues, both from the donor and acceptor (patient) point of view. The conclusion is that under a series of restrictions intended to prevent the use of grafts from encouraging induced abortions and to maintain high standards of respect for life and human dignity, neurotransplantation using embryonic or fetal brain tissue parts cannot be rejected on moral grounds.     

Innovation across cultures: Connecting leadership,identification, and creative behavior in organizations

Innovation is considered essential for today's organizations to survive and thrive. Researchers have also stressed the importance of leadership as a driver of followers' innovative work behavior (FIB). Yet, despite a large amount of research, three areas remain understudied: (a) The relative importance of different forms of leadership for FIB; (b) the mechanisms through which leadership impacts FIB; and (c) the degree to which relationships between leadership and FIB are generalizable across cultures. To address these lacunae, we propose an integrated model connecting four types of positive leadership behaviors, two types of identification (as mediating variables), and FIB. We tested our model in a global data set comprising responses of N = 7,225 participants from 23 countries, grouped into nine cultural clusters. Our results indicate that perceived LMX quality was the strongest relative predictor of FIB. Furthermore, the relationships between both perceived LMX quality and identity leadership with FIB were mediated by social identification. The indirect effect of LMX on FIB via social identification was stable across clusters, whereas the indirect effects of the other forms of leadership on FIB via social identification were stronger in countries high versus low on collectivism. Power distance did not influence the relations.     

Do pain expectancies cause pain in chronic low back patients? A clinical investigation

The present study investigated whether pain expectancies cause pain in chronic low back patients. Back patients (N = 29) were requested to perform four exercise bouts (two with each leg), each consisting of flexing and extending the knee three times at maximal force (Cybex 350 System). During each exercise bout the baseline pain, the expected pain and experienced pain were recorded. Patients also reported their experienced fear of further injury to the back. Furthermore, the peak force of both knee flexors and extensors was assessed. Although patients did expect a back pain increase during the first exercise bout with each leg, no evidence was found for the thesis that pain expectancies generate increases in subjective pain experiences. Instead, the reported pain expectancy was readily corrected during the next exercise bout, whereas the experienced pain remained unchanged. Furthermore, a high pain expectancy co-occurred with (1) a marginally significant fear of (re)injury, and (2) a significant lower peak torque of the knee flexors. These results are consistent with conditioning models which state that pain expectations are associated with a fear response and an urge to avoid the pain.
