Internal And External Validity

Abstract: Recently, Duriez, Fontaine and Hutsebaut (2000) and Fontaine, Duriez, Luyten and Hutsebaut (2003) constructed the Post-Critical Belief Scale in order to measure the two religiosity dimensions along which Wulff (1991 , 1997 ) summarized the various possible approaches to religion: Exclusion vs. Inclusion of Transcendence and Literal vs. Symbolic. In the present article, the German version of this scale is presented. Results obtained in a heterogeneous German sample (N = 216) suggest that the internal structure of the German version fits the internal structure of the original Dutch version. Moreover, the observed relation between the Literal vs. Symbolic dimension and racism, which was in line with previous studies ( Duriez, in press ), supports the external validity of the German version.

Insight Into

Rejection Sensitivity (RS) is defined as the disposition to anxiously expect, readily perceive, and overreact to social rejection cues. Aim of the two studies presented in this paper was to develop and administer an instrument to assess RS in a German sample of healthy (pre)adolescents as well as in a clinical sample. The English Children’s Rejection Sensitivity Questionnaire (CRSQ) was translated, adapted, and presented to a non-clinical sample (N = 128) (Study I) to identify psychometric properties of the instrument. In Study II, the resulting questionnaire was completed by a mixed clinical sample (N = 50). Differences in results between samples, and the relation between rejection sensitivity and mental distress were investigated. The resulting German version of the questionnaire CRSQ (German: Fragebogen zur Zurückweisungsempfindlichkeit für Kinder und Jugendliche, FZE-K) showed good psychometric properties. Differences between samples provide insight into the diversity of the construct “rejection sensitivity”.

Abstract Background Patients and their families often have preferences for medical care that relate to wider considerations beyond the clinical effectiveness of the proposed interventions. Traditionally, these preferences have not been adequately considered in research. Research questions where patients and families have strong preferences may not be appropriate for traditional randomized controlled trials (RCTs) due to threats to internal and external validity, as there may be high levels of drop-out and non-adherence or recruitment of a sample that is not representative of the treatment population. Several preference-informed designs have been developed to address problems with traditional RCTs, but these designs have their own limitations and may not be suitable for many research questions where strong preferences and opinions are present. Methods In this paper, we propose a novel and innovative preference-informed complementary trial (PICT) design which addresses key weaknesses with both traditional RCTs and available preference-informed designs. In the PICT design, complementary trials would be operated within a single study, and patients and/or families would be given the opportunity to choose between a trial with all treatment options available and a trial with treatment options that exclude the option which is subject to strong preferences. This approach would allow those with strong preferences to take part in research and would improve external validity through recruiting more representative populations and internal validity. Here we discuss the strengths and limitations of the PICT design and considerations for analysis and present a motivating example for the design based on the use of opioids for pain management for children with musculoskeletal injuries. Conclusions PICTs provide a novel and innovative design for clinical trials with more than two arms, which can address problems with existing preference-informed trial designs and enhance the ability of researchers to reflect shared decision-making in research as well as improving the validity of trials of topics with strong preferences.

Internal And External Validity

Background: The Thiel embalmment method has recently been used in a number of medical simulation fields. The authors investigate the use of Thiel vessels as a high fidelity model for microvascular simulation and propose a new checklist-based evaluation instrument for microsurgical training. Methods: Thirteen residents and 2 attending microsurgeons performed video recorded microvascular anastomoses on Thiel embalmed arteries that were evaluated using a new evaluation instrument (Microvascular Evaluation Scale) by 4 fellowship trained microsurgeons. The internal validity was assessed using the Cronbach coefficient. The external validity was verified using regression models. Results: The reliability assessment revealed an excellent intra-class correlation of 0.89. When comparing scores obtained by participants from different levels of training, attending surgeons and senior residents (Post Graduate Year [PGY] 4-5) scored significantly better than junior residents (PGY 1-3). The difference between senior residents and attending surgeons was not significant. When considering microsurgical experience, the differences were significant between the advanced group and the minimal and moderate experience groups. The differences between minimal and moderate experience groups were not significant. Based on the data obtained, a score of 8 would translate into a level of microsurgical competence appropriate for clinical microsurgery. Conclusions: Thiel cadaveric vessels are a high fidelity model for microsurgical simulation. Excellent internal and external validity measures were obtained using the Microvascular Evaluation Scale (MVES).

<p>We are pleased to present a new issue of AJET and in the editorial we would like to discuss some of the challenges involved in undertaking and reporting on experimental research in education and in educational technology specifically. The first challenge relates to the need to find the right balance between internal and external validity in the research design, while the second relates to the need for clarity about the likely causes of learning effects: technology or learning design.</p>

Internal And External Validity

This paper highlights the impacts of a revised curriculum which incorporated a strong life skills focus into an existing civic education curriculum (for 4-H youth). The revised curriculum resulted in actual youth gains in life skills competencies. The study also explored the effect of volunteer facilitators in the implementation of an added life skills training component. Despite some significant limitations to the internal and external validity of the study, preliminary indications were that adding explicit life skills training content does in fact lead to an increase in life skills competencies. This was clearer in cases where volunteer facilitators fully implemented the additional content versus implementing none or only part of the life skills training. The limitations of the study and suggestions for future research are outlined in the conclusion.

Internal And External Validity

Attachment styles are often primed by having participants recall and describe a relationship that is prototypical of a given attachment style. Researchers may exclude participants who cannot recall such a relationship, or who describe relationships that do not conform to the assigned prime. I suggest that excluding participants is untenable, and may threaten a study’s validity. In the present research, I examine predictors of exclusion from an attachment priming study. Priming insecure attachment resulted in greater odds of exclusion relative to a control condition. Female participants with greater sexual experience also had lesser odds of exclusion. These results suggest that attachment-priming procedures contribute to participant exclusion that compromise internal and external validity. Discussion focuses on directions for future attachment-priming research.

Microcredit has long stood as a flagship topic for RCTs in development, starting with the publication of a special issue in a leading economics journal on six RCTs conducted in different world regions. This special issue was hailed as the first rigorous and conceivably definitive study on the impacts of microcredit. However, a detailed exploration of the implementation of these six RCTs reveals many limitations with respect to internal and external validity, ethics, and interpretation. This chapter uses analytical tools from statistics, political economy, and development anthropology to discuss the extent to which the entire RCT chain strays from the ideal RCT principles (from sampling, data collection, data entry and recoding, estimates and interpretation to publication and dissemination of results). It also raises questions about the disparity between the academic and political success of this special issue and the many inconsistencies of method.
