Purpose. Using the Problem Oriented Screening Instrument for Teenagers (POSIT), the effect of mode of administration on (1) students' willingness to disclose sensitive information and (2) response rates was investigated. Design. A2 × 2 unequal N factorial analysis of variance (ANOVA) design was employed. Mode of administration (paper-and-pencil vs. Web-based) was crossed with grade level (middle vs. high school). Setting. The study was conducted in two middle and two high schools. Subjects. A total of 628 middle and high school students completed the survey. Measures. The POSIT is a self-report measure with 139 yes/no items that identifies stressors in 10 functional areas (e.g., Substance Use). Analysis. An unequal N 2 (mode) × 2 (grade level) factorial ANOVA was employed. Results. No statistically significant differences were found for self-reported risk across modes of administration. Students completing the Web-based version of the survey were four times more likely to skip an item. Conclusions. Effect of Mode on Reporting of Sensitive Information—Students completed the Web-based surveys in computer labs with other students. The intent of the Web-based survey was to increase perceived privacy but the environment likely negated any effect. Effect of Mode on Response Rates—The higher response rate for the paper-and-pencil survey was the opposite of what was expected and revealed that students were more likely to skip sensitive items on the Web survey.

This study examined the psychometric equivalence of paper-and-pencil and Internet formats of key questionnaires used in couple research. Self-report questionnaires assessing interpersonal constructs (relationship satisfaction, communication/conflict management, partner support, emotional intimacy) and intrapersonal constructs (individual traits, psychological symptoms, contextual influences) were administered to young adults in committed dating relationships. The same measures were administered twice via paper-and-pencil and/or Internet methods over a 2-week period. Method order was counterbalanced among participants, and temporal stability was controlled. Intrapersonal and interpersonal measures generally remained reliable when administered online and demonstrated quantitative and qualitative equivalence across methods. The implications of online administration of questionnaires are discussed, and specific recommendations are made for researchers who wish to transition to online data collection.

The psychometric properties of two paper-and-pencil versions of the Children’s Attributional Style Interview (i.e., CASI-I and CASI-II) were evaluated in a sample of 166 third and fourth graders and a sample of 245 sixth and seventh graders. The results demonstrated strong internal consistency reliability, convergent validity, and a factor structure that was consistent with theory in both samples. Furthermore, analyses demonstrated adequate evidence of the reliability and validity of several dimensional subscale scores and the composite measures of attributional style for both positive and negative events. These results suggest the utility of the CASI in research testing specific attributional predictions of cognitive theories of depression with the dimensional subscale scores. They further add to the literature by demonstrating item-level factor analytic support for a children’s attributional style measure and the feasibility of administration sizes larger than previously tested, which add to the utility of the CASI in large-scale research designs.

Screening for hypothyroidism has been achieved by seeking raised concentrations of thyroid stimulating hormone (h-TSH) in dried blood samples collected on absorbent paper from some 1700 newborn babies each week using double antibody radioimmunoassay and 125I-label counting on a NE1600 gamma counter linked to a HP9815S desk top calculator. Specificity, accuracy, and quality control of the assay have been investigated. The calculator programme stores all count, time, and calculated data and uses log-log function formation and third-power homoscedastic polynomial fit to the calibration data followed, if necessary, by elimination of outliers set at p= 0·5 %. Branching in the calculation procedure provides the ability to process sample data in subgroups, completely to reprocess data (including presentation in a form suitable for making a histogram plot), and to reset without loss of data in case of instrument or main power failure. Variance analysis was used to select the minimum duration of count (50 s), and it was demonstrated that homoscedasticity pertains in the regression calculation.
