Abstract
BackgroundPedestrians’ unsafe crossing behavior exposes them at risk of trauma and death and puts a tremendous burden on the health care system. The theory of planned behavior (TPB) is one of the leading theoretical models used to develop pedestrians’ road crossing behavior questionnaires, yet the quality of measurement properties of them has not been evaluated. The aim of the proposed systematic review is to evaluate the quality of measurement properties of the questionnaires constructed based on the TPB to predict pedestrians’ road crossing behavior.MethodsWe will include studies validating or evaluating one or more psychometric properties of the self-reported questionnaire employing the TPB for predicting pedestrians’ road crossing behavior. A comprehensive search strategy will be formulated based on the components of review aim. The databases of MEDLINE, Embase, PubMed, Cochrane Library, PsycINFO, PsycARTICLES, and ProQuest, also grey literature and the reference lists of the included studies, will be searched. A hand search for the relevant journals and Google Scholar will be conducted. COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias checklist will be used to evaluate the measurement properties of the included questionnaires. First, we will assess standards for the methodological quality of each study. Then, each scale or subscale of a questionnaire will be rated using the updated criteria for good measurement property. We will quantitatively pool or qualitatively summarize the results and will evaluate them against the criteria for good measurement properties. Finally, we will grade the pooled or summarized evidence using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach and provide recommendations for the most appropriate instrument.DiscussionThe proposed systematic review will evaluate the measurement properties of self-report pedestrians’ road crossing behavior questionnaires constructed based on the TPB. The findings will help researchers in selecting the appropriate TPB-based instrument for pedestrians’ road crossing behavior.Systematic review registrationPROSPERO CRD42017047793

Pedestrians’ unsafe crossing behavior exposes them at risk of trauma and death and puts a tremendous burden on the health care system
Unsafe road crossing behavior exposes them to risk of trauma and death and imposes a heavy burden on the health care system [5, 6]
The high rate of pedestrian injury and mortality highlights the importance of an urgent call for evidencebased health education and safety promotion programs [8]
Summary
A multidisciplinary research team which consists of the following members prepared this protocol and will conduct the main review: MM, a full professor in Health Education & Promotion, is an expert in the theory of planned behavior. Type of instrument We will consider primary studies that have presented pedestrian self-reported TPB-based questionnaire to predict road crossing behavior or intention. For the evaluation of each MP of the TPB-based pedestrian behavior, first, we will assess standards for the methodological quality of each study on MP using the corresponding COSMIN RoB checklist and applying a 4-point rating scale: very good, adequate, doubtful, and inadequate. The characteristics of the included PROMs will consist of the name of the PROMs, reference to the PROM development article, constructs being measured, language and study population for which the PROM was developed, intended context of use, available language version of the PROM, number of scales or subscales, number of items, response options, and recall period. Group “C” will not recommend for use because there is strong evidence for an insufficient MP [31]
