Parents can influence their children’s problematic mobile phone involvement (PMPI) by engaging in parental mediation activities, such as restrictions or co-use, by being a role model, and by their general and domain-unspecific parenting style that facilitates more or less attachment security of the child. This study tested the associations between these different routes of influence—parental mediation of the mobile phone, parental PMPI, and secure child-parent attachment—with children’s PMPI. Data was acquired from a quota-sample survey with 500 children, between 8 and 14 years of age, and one of their parents. Results point to the importance of open and empathic parent-child-communication, as well as a positive relationship quality, and demonstrate the detrimental effects of parents’ own PMPI on children’s PMPI. 相似文献

ABSTRACTIn December 2015 the Executive Committee of the World Psychiatric Association accepted a position statement on spirituality and religion in psychiatry. In this contribution the author will (briefly) sketch the background of the development of this position statement, and the criteria it needs to fulfil. The aim of the final result will be explained, and some desiderata with regard to its future will be expressed. The full text of the Position Statement as it has been published in World Psychiatry (February 2016) is added as appendix (permission granted by the editor). 相似文献

Background: nursing students are required to think reflectively in both real and simulated clinical practice. Although the Reflective Thinking instrument is reliable in its measurement of reflective thinking, its validity is unknown. Method: confirmatory factor analysis was undertaken in an iterative manner within a non-equivalent control-group study to measure nursing students’ reflective thinking and satisfaction with high-fidelity simulation. The validity and reliability of the Reflective Thinking instrument was tested. Results: the resulting instrument consisted of 15 items across four factors. The final model was plausible as it demonstrated ‘goodness of fit’; however, it had neither convergent or discriminatory validity, nor reliability. Internal consistency was fair to reasonable for the four subscales. Conclusion: the testing of the Reflective Thinking instrument using confirmatory factor analysis is a vital initial step in the modification of this instrument. Further development using exploratory factor analysis will enhance the instrument’s relevance within high-fidelity simulation. 相似文献

Using an experimental design that measures participants’ actual behavior, this study tests the inclusion of a perceived outgroup in an advertisement for a well-established brand to determine if political orientations interact with an advertisement’s content to predict consumption of that product. The results indicate that an advertisement’s activation of one’s political orientation can either change or reinforce brand loyalty. Specifically, more conservative individuals responded to the presence of Muslim and Arab individuals in a Coca-Cola advertisement by selecting Pepsi products despite their initial preference for Coca-Cola; whereas, more liberal individuals maintained their initial brand loyalty to Coca-Cola. 相似文献

The Tobii Eyex Controller is a new low-cost binocular eye tracker marketed for integration in gaming and consumer applications. The manufacturers claim that the system was conceived for natural eye gaze interaction, does not require continuous recalibration, and allows moderate head movements. The Controller is provided with a SDK to foster the development of new eye tracking applications. We review the characteristics of the device for its possible use in scientific research. We develop and evaluate an open source Matlab Toolkit that can be employed to interface with the EyeX device for gaze recording in behavioral experiments. The Toolkit provides calibration procedures tailored to both binocular and monocular experiments, as well as procedures to evaluate other eye tracking devices. The observed performance of the EyeX (i.e. accuracy < 0.6°, precision < 0.25°, latency < 50 ms and sampling frequency ≈55 Hz), is sufficient for some classes of research application. The device can be successfully employed to measure fixation parameters, saccadic, smooth pursuit and vergence eye movements. However, the relatively low sampling rate and moderate precision limit the suitability of the EyeX for monitoring micro-saccadic eye movements or for real-time gaze-contingent stimulus control. For these applications, research grade, high-cost eye tracking technology may still be necessary. Therefore, despite its limitations with respect to high-end devices, the EyeX has the potential to further the dissemination of eye tracking technology to a broad audience, and could be a valuable asset in consumer and gaming applications as well as a subset of basic and clinical research settings. 相似文献
