Experimental evaluation of public policy: the case of state legislation for child passenger safety.

Observations of children in automobiles were made in seven states before and after implementation of legislation requiring use of child passenger safety devices. Increases in safe seating for children covered by state laws and children under 1 year old were observed in three of the five states implementing legislation during this study. Decreases in safe seating for these age groups were observed in two states, however. Increases in safe seating for children from 1 to 5 years old were observed in four of these five states. Although methodological limitations require cautious interpretation, these data suggest the impact child safety seat laws may have on compliance. Implications of this research for policies on child passenger safety and the importance of exploiting naturally occurring public experiments are discussed.     

THE INFLUENCE OF CHILD-PREFERRED ACTIVITIES ON AUTISTIC CHILDREN'S SOCIAL BEHAVIOR

One of the characteristics of autistic children is severe social avoidance behavior. We assessed whether the type of activity (child-preferred vs. activities that were arbitrarily determined by an adult) engaged in during an interaction was correlated with the amount of social avoidance behaviors these children exhibit. Results revealed a negative correlation between appropriate child-preferred activities and social avoidance behavior. Additional analyses revealed that (a) social avoidance behaviors could be manipulated within a reversal design, and would predictably decrease when the children were prompted to initiate appropriate child-preferred activities; and (b) these procedures could be used to teach children to initiate child-preferred activities in community settings, resulting in reductions in social avoidance responses even after the therapist's prompts were completely removed. These data suggest that the manipulation of task variables may influence the severe social unresponsiveness that is characteristic of autistic children.     

A probabilistic model of intensive designs

Without internal validity, experimental data are uninterpretable. With intensive designs, most methods presented to quantify a design's internal validity have been subject to criticism. A probabilistic model of intensive designs is presented that demonstrates the high degree of internal validity of these designs without relying on adaptations from traditional inferential statistics. Where the experimenter is able to conform to the restrictions of the model, the equations provide an estimation of internal validity for either reversal or multiple-baseline designs. More importantly, the model provides mathematical bases for some of the common recommendations and design considerations in intensive research (such as the desirability of within-subject replications and of four or more multiple baselines).

Training to be a volunteer Rape Crisis counsellor: a qualitative study of women's experiences

This is an account of a qualitative study designed to elicit and analyse the narratives of women who had trained to be volunteer counsellors at a Rape Crisis centre. Little prior research has focused on the experiences of workers in Rape Crisis centres and this project was designed to explore women's experiences in ways that were meaningful to them. The research methods used were face-to-face, unstructured, in-depth individual interviews and group sessions. Participants in the individual interviews had all undertaken Rape Crisis training within the preceding two years. The group sessions involved all workers who were actively involved with the Rape Crisis centre at the time of the research. Five themes emerged from an inductive analysis of the data: motivation to train, complexity and change, changes in personal relationships, personal change and feminism. Overall the study highlights the complex, transformative processes that volunteer Rape Crisis counsellors may experience. The article concludes by identifying implications for practice that may serve to enhance training for volunteer counsellors in the future.     

Commentary on Special Section on “Bidirectional Parent–Child Relationships”: The Continuing Evolution of Dynamic,Transactional Models of Parenting and Youth Behavior Problems

Creative and methodologically sophisticated longitudinal research on bidirectionality in parenting and child behavior can shed important new light on the dynamics of behavior-problem development. The articles assembled for this Special Section are at the forefront of efforts aimed at tracing the interplay of parenting behavior and child and adolescent adjustment problems over time. In this commentary, we provide a brief overview of thinking and research on bidirectionality and then highlight key themes and findings reported in these articles. We describe some of the challenges in research on bidirectional processes and offer some recommendations for future research in this area.     

A Multi-Dimensional Framework for Evaluation of Instructional Consultation Teams

ABSTRACT

This article describes a multidimensional framework for evaluating team-based services in schools. The theory and literature on developmental, causal and confirmatory program evaluation are discussed as the foundation for this framework. The model of Instructional Consultation Teams (IC-Teams) is presented as an illustration of how program evaluation research supports program development and provides evidence of program impact. The inferred impact of IC-Teams upon over-referral and identification of students for special education, especially minority students, is investigated using the confirmatory criteria of consistency. Three studies investigating the impact of IC-Teams upon special education referrals of the IC-Team model are presented. The studies, conducted across three implementations of the program with three different methodologies, demonstrated decreases in the referral, evaluation and placement of students in special education. The need for additional research and limits of the approach are discussed.     

Topic-relevant cognition and empathic accuracy in laboratory discussions of safer sex

Abstract

The present study sought to identify some of the mechanisms that make safer sex such a difficult topic to talk about. Fifty six dating couples participated in a laboratory study in which the opposite-sex members of two pairs of couples engaged in two discussions of safer sex (or a control topic), each time with a different opposite-sex partner (their own dating partner or an opposite-sex stranger). The results indicated that discussions of safer sex evoke in dating partners a high level of perceived goal-incompatibility, difficulty maintaining one's focus on the topic, and difficulty in reading the other partner's thoughts and feelings. These reactions did not occur in response to the control topic. This initial demonstration study is important with respect to the processes it implicates, but further clarification is needed regarding the specific real-life conditions in which these processes do, and do not, occur.

Developing clinical effectiveness in psychotherapy training: Action research

This study is an evaluation of a new approach to clinical training in Transactional Analysis using the methodology of action research. The evaluation focuses on the second year of training and placement‐based clinical practice at the Metanoia Institute, UK. The design of the training year was research‐based and used the concept of an ‘internship’ year. The design aimed to close the gaps between clinical practice, supervision and formal training; facilitate translation of theory into practice; and integrate findings from the ‘common factors’ research into effectiveness of psychotherapy. Training and supervision methods were linked and focused on emerging issues in clinical practice and the development of students’ capacity for critical reflection and a research attitude to practice. The evaluation was a naturalistic study which used quantitative and qualitative methodology within the action research framework to reflect on the impact of the training on the participants, the organisation and the clinical practice. The quantitative outcomes show that the project developed the effectiveness of students’ clinical practice and reflexivity. Qualitative analysis gives insight into the experiences of the participants and the emotional impact of the research process.
