Understanding and Improving the Validity of Self-Report of Parenting

Although researchers using parental self-report data have questioned its validity (Holden, 2001) and called for more work in this area (Krevans & Gibbs, 1996; Locke & Prinz, 2002), methodological concerns regarding self-report about parenting practices have not been addressed adequately. The susceptibility of parental report to systematic distortions suggests a need for research on ways to improve self-report. This paper attempts to synthesize research findings from other fields (e.g., survey methodology) about ways to improve the validity of self-report, and to discuss the implications for self-report of parenting behaviors. Methods for improving self-report are presented for each of the 5 major tasks in responding to a question: (1) understanding the question, (2) recalling relevant behavior, (3) inference and estimation, (4) mapping the answer onto the response format, and (5) “editing” the answer for reasons of social desirability. Self-administered interviewing, audio-computer-assisted interviewing, pretesting, conversational interviewing, and the decompositional item may be among the best candidates for use in parental self-report. Recommendations are offered with respect to strategies that might prove useful in improving parental assessment of parenting, and to research efforts to evaluate the utility and potential costs of these strategies.     

Binocular coordination of the eyes during reading: word frequency and case alternation affect fixation duration but not fixation disparity

This experiment investigated whether properties of the text being read affect binocular coordination of the eyes during reading. Readers' binocular eye movements were recorded while they read sentences that contained high- and low-frequency words. In addition, half of the sentences were presented in normal case, and half were presented in alternating case (i.e., AlTeRnAtInG cAsE). Past research has suggested that the visual system tolerates less binocular fixation disparity with alternating than with normal case (Heller & Radach, 1999). While both word frequency and alternating case produced large effects on fixation durations on the target word, neither manipulation affected the magnitude of fixation disparity. It is concluded that linguistic and visual properties of the text being read do not influence binocular coordination of the eyes during reading. Additional analyses also showed no difference in fixation disparity between reading and a nonlinguistic task. Implications of these results for split-fovea models of reading are discussed.
