Standardizing the Assessment of Citizen Scientists’ Motivations: A Motivational Goal-Based Approach

Abstract

Understanding volunteers' motivations to participate in Citizen Science (CS) projects is essential for these projects' effective management and success. Many studies have investigated citizen scientists' motivations, but only a few have used a theory-based approach to provide a standardized methodology to measure CS motivations. The current research aims to take the literature a step further by developing and applying a general, standardized, theory-based framework of CS motivation and a CS motivation scale (CSMS) that can be used to assess volunteers' motivations across diverse CS projects. The CSMS comprises 58 items corresponding to 15 motivational categories. It is grounded in Schwartz's theory of basic human values, while incorporating the wealth of empirical knowledge on citizen scientists' motivations. We administered the scale to three separate samples of either Dutch or Hebrew-speaking participants who volunteered for three CS projects. Analysis of participants' ratings of their motivations supported our theoretical framework, showing that 13 of the scale's 15 motivational categories fell into 4 higherorder motivations, which correspond to Schwartz's theory of values: openness to change, self-enhancement, continuity (conservation), and self-transcendence. Results further provide concrete insights into CS participation behavior, showing that certain motivations (including help with research, benevolence, and self-direction) were consistently among the most important motivators for participation across CS projects. Finally, we found that prioritizing certain motivations can also predict participation behavior (e.g., duration of participation and willingness to participate in additional volunteering activities). The CSMS is a new tool that can be applied across projects spanning diverse domains and populations, advancing and standardizing the growing literature on CS motivations. design, data analysis, and writing.

Learners, Not Just Data Contributors: Self-Regulated Learning in Citizen Science

“…A large number of studies have focused on the motivations of participants in citizen science, and have found a variety of motivational factors, such as, love of science, environmental concerns, support research efforts, as well as wanting to learn and gain knowledge [24,30]. Whereas, very few research have used a theorybased approach to measure motivation in citizen science with standardized methodology [31]. Achievement goal theory provides a framework for understanding the motivational factors that propel volunteers to complete tasks in citizen science projects, highlighting how situational influences can shape motivation.…”

The science of citizen science: a systematic literature review on educational and scientific outcomes

“…For instance, scales to measure attitudes have been developed and evaluated by, for example Kind et al (2007), Lederman et al (2014), andHartman et al (2017). Levontin et al (2022) suggest a standardized, theory-based approach to measure participants' motivation in a comparable manner. These measures ensure the validity of the intended interpretation of the results and enable further development of basic scientific theories.…”

Demographic and motivational differences between participants in analog and digital citizen science projects for monitoring mosquitoes

“…Although most studies focusing on motivation in citizen science do not explicitly state an underlying theory 41 , a review of the literature shows that multiple frameworks, ranging from Baston, Ahmad, and Tsang’s community involvement 42 , Ajzen’s theory of planned behavior 41 to the most commonly used model of Calary’s and Snyder’s Volunteer Functions Inventory (VFI) have been previously called upon 43 . In order to process motivational variations beyond exclusive categories, and avoid the exclusion of motivational goals, recent studies by Palacin et al 44 and Levontin et al 43 have made use of Schwartz’s Theory of Basic Human Values 45 .…”
