Psychometric Evaluation of the Parent Situation Inventory: A Role-Play Measure of Coping in Parents of Substance-Using Adolescents.

This article reports on the generalizability, reliability, and construct validity of the Parent Situation Inventory (PSI), a role-play measure of coping skills in parents experiencing problems from an adolescent's drug and alcohol use. Generalizability was robust (.80) and alternate form and test-retest reliability were satisfactory. PSI skillfulness was negatively related to the parent's own substance use and to the adolescent's alcohol use. The PSI shows promise as a reliable and potentially valid measure of coping in this population and has direct implications for developing and evaluating skill-based parent training programs.

Future train traffic control: control by re-planning

Improving train traffic control can be a cost-efficient way to improve train traffic punctuality and increase utilization of existing and future railway infrastructure. However, performance in train traffic control tasks currently involves working on a technical level in order to regulate the traffic flow. Working in a preventive manner is poorly supported and train traffic controllers are usually restricted to just solving problems as they occur. This often results in unnecessarily long delays and decreased timeliness of train traffic. The main objective of this paper is to describe a proposed control strategy and a case study, which evaluates the control strategy and the prototype tool derived from the research. By shifting the control paradigm to a high-level control strategy, many of today’s problems may be avoided, with benefits of the reduction in delays, improved timeliness and better utilization of the infrastructure. Twenty-one train traffic controllers participated in a case study, with a simulated prototype environment. The majority of the participating train traffic controllers were positive to the new concepts and ideas. Many of the important aspects of the proposed control strategy can be investigated with the simulation, but due to the complexity of train traffic some issues must be evaluated in an operative environment.

Team situation assessment and information distribution

Described is the cooperative work of constructing team situation awareness within two teams of a military command and control unit. Specifically discussed is how the distributed cognitive and cooperative work of decision-making of the two teams is structured. The situation enabled two different ways of distributing information within the team: one serial and one parallel. One team chose the parallel information transfer, the other the serial one. Discussed is the interaction patterns that emerge in the respective teams and their consequences for situation assessment and situation awareness. The differences are then discussed in terms of means of sharing information. Some hypotheses for future research are also offered.
