“…The C q items have demonstrated reliability and validity [29-31], and are consistent with measures used in national surveillance tools or to measure current national public health guidelines [28,32-34]. Consistent with other research [35], the cover page of the C q contains measures required to create a unique self-generated code for each respondent in a school to ensure the anonymity of the survey participants, while still allowing COMPASS researchers to link each student’s unique anonymous identifier data over multiple years. Eligible students completed the C q in class on the day of the scheduled data collection for their school at a time coordinated by COMPASS staff and school administration.…”

BackgroundFew researchers have the data required to adequately understand how the school environment impacts youth health behaviour development over time.Methods/DesignCOMPASS is a prospective cohort study designed to annually collect hierarchical longitudinal data from a sample of 90 secondary schools and the 50,000+ grade 9 to 12 students attending those schools. COMPASS uses a rigorous quasi-experimental design to evaluate how changes in school programs, policies, and/or built environment (BE) characteristics are related to changes in multiple youth health behaviours and outcomes over time. These data will allow for the quasi-experimental evaluation of natural experiments that will occur within schools over the course of COMPASS, providing a means for generating “practice based evidence” in school-based prevention programming.DiscussionCOMPASS is the first study with the infrastructure to robustly evaluate the impact that changes in multiple school-level programs, policies, and BE characteristics within or surrounding a school might have on multiple youth health behaviours or outcomes over time. COMPASS will provide valuable new insight for planning, tailoring and targeting of school-based prevention initiatives where they are most likely to have impact.

“…Response rates to the four surveys varied, partly due to changes in participant addresses over an 18-month period, but primarily due to ethical considerations in ensuring anonymous responses. Participants assigned themselves a self-generated identification code to be used by researchers to match the four surveys, as this method has been shown to be successful for ensuring participant anonymity in linking longitudinal questionnaire data (Kearney, Hopkins, Mauss, & Weisheit, 1984). Several months later generic follow-up reminders were sent to the entire list.…”

The Dynamic Nature of Justice: Influential Effects of Time and Work Outcomes on Long-Term Perceptions of Justice

2010

Competing hypotheses are used to test whether justice perceptions change over time, and if so, whether the changes become more polarized over time (more positive or negative) or whether the changes fluctuate over time based on subsequent work outcomes. Results suggest there is no polarizing or fluctuating effect in perceptions of interpersonal justice over time and no polarizing effect in perceptions of procedural justice for individuals with high initial perceptions of procedural justice. However, individuals with low initial perceptions of procedural justice increased procedural justice perceptions over time, resulting in a polarizing effect in the opposite direction of the prediction. Hierarchical regression analysis indicates initial perceptions of procedural justice tend to fluctuate over time due to intervening work decision outcomes, although in the opposite direction of what was predicted.

“…The self-generated identification code, although a unique solution to maintaining anonymity in longitudinal studies, is not without problems. Researchers note that the process of matching responses is less than perfect, and the success of matching is indirectly proportional to the time between administrations (Kearney, Hopkins, Mauss, & Weisheit, 1984). Success of matching is fairly high (>90%) for questionnaires administered within days of each other but lower (78%) for responses obtained a year apart (Kearney et al).…”

An evaluation of a self-generated identification code

We describe a self-generated coding form used in a study of HIV prevention practices of college students and provide information on the success rate of matching questionnaires over a 3-year period using the form. The data for this study were from a longitudinal study of HIV risk-reduction practices of college students. In order to match questionnaires over the 3-year study period while maintaining anonymity, participants were asked to complete a self-generated identification form at each data collection point. In the second year of the project, we were able to successfully match 74.3% of the questionnaires to those returned during the first year using 6 to 8 of the code elements on the form, and in the third year, we were able to match 73% of questionnaires to those returned in the second year. Participants for whom questionnaires matched were more likely than participants with unmatched questionnaires to be white students enrolled as underclassmen.
