Summary
A new web-based questionnaire effectively assesses skydiving pain incidents and risks. This validated tool is suitable for epidemiological studies on skydivers, improving data collection for injury prevention.
Area of Science:
- Sports Medicine
- Epidemiology
- Human Factors in Aviation
Background:
- Parachuting injuries are a known issue in military and recreational skydiving.
- Sub-clinical incidents, like those from opening shock, are understudied.
- No validated questionnaire exists for skydiving exposure assessment.
Purpose of the Study:
- To validate a web-based questionnaire for assessing pain incidents and related risks in Swedish skydivers.
- To establish a tool for epidemiological research in the skydiving population.
- To facilitate data collection on skydiving exposures.
Main Methods:
- A web-based questionnaire was developed and piloted with 102 skydivers.
- Content and face validity were assessed by a panel of seven medical and skydiving experts.
- Item Content Validity Index (I-CVI) and Scale-CVI were calculated; face validity used open-ended reviews.
Main Results:
- 18 of 19 items achieved an I-CVI of 0.86 or higher; the last item had an I-CVI of 0.71.
- The overall Scale-CVI was 0.95, indicating high content validity.
- The final questionnaire version demonstrated 'good' or 'really good' face validity.
Conclusions:
- The developed web-based questionnaire is validated for epidemiological and clinical research among skydivers.
- This tool offers a reliable method for assessing skydiving-related pain and risks.
- It supports future research into injury prevention and risk factors in skydiving.

01:07Data Collection by Survey
The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...
01:28Survey Safety
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...
02:16Surveys
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
01:27Types of Surveys
Surveys are essential for marking property boundaries near water bodies. Different types of surveys are defined, each with its own function. Land surveys mark the property boundaries, while route surveys determine the position of properties on nearby highways. Topographic surveys create maps by capturing the three-dimensional features of the land. Hydrographic surveys focus on the shapes of underwater areas and the movement of streams through the properties. Mine surveys determine the relative...
01:29Reliability and Validity
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
01:16Response Surface Methodology
Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:
