The present study’s aim was to develop a psychometrically robust, valid and reliable instrument to assess public law-abiding beliefs and practices among individuals. Based on the present limited literature on the concept of being law-abiding as well as feedback from the expert panel members and lay people in the development phase, a scale for assessing the law-abiding beliefs and practices was successfully developed (i.e., Public Law-Abiding Beliefs and Practices Scale [PLABPS]).
In the content validity evaluation phase, two items (Item 13 and Item 16) were discarded. Item 13 did not achieve adequate CVR by the expert panel, probably due to the fact that in most countries there is no enforceable rule or social punishment to warn or punish individuals who spit in public places. Also, Item 16 was deleted due to low clarity and relevancy of the item. Additionally, EFA did not support the inclusion of Items 1, 3, 5 and 8. Item 1 (smoking in public places) tended to be loaded on a single factor and was therefore removed. Removing these aforementioned items significantly improved the model fit measures. Sequential item reduction using exploratory factor analysis showed that items on traffic laws tend to be loaded on a separate factor and parallel analysis confirmed that the scale best fitted into two factors. The final scale included 10 items which appear to be widely accepted public regulations in most civilized countries.
Regarding some items, individuals might not have ever experienced specific situations (for example, some individuals might never have driven a car). Since the overall goal of the scale was to assess law-abiding tendency, individuals could assess the items according to their opinions and beliefs toward that specific item based on their previous observations in their daily life, even though they may have not had any personal experience with that situation.
The present authors believe that scale items are generalizable to most parts of the world, since most items are based on moral and ethical bases. The resultant model showed a robust structure with good reliability and validity indices. Furthermore, the results of convergent, divergent, and known-groups validity evaluations showed that the scale corresponded well with the main expected goal of the study and was able to differentiate individuals with different levels of law-abiding tendency. Therefore, the PLABPS has the potential for future use to explore psychosocial factors associated with adherence to social regulations. Additionally, the PLABPS may serve as a research tool that can be used across different nations, cultures, and communities.
Obviously, governmental laws and social norms can be different at the country and sub-country levels, and this might be the reason why there has not been (until now) a general international scale to assess how much a country’s people follow public rules and regulations. However, as there is increasingly more international relations among different countries, more similarities can be found with public regulations and social norms across the world.
The present study also found a significant association between individuals’ public law-abiding tendency and their self-reported safe COVID-19 practices. The COVID-19 pandemic was a good example of how people’s behavior with respect to public health-related regulations could affect the society as whole. Additionally, some of the public laws, directly or indirectly, can affect people health22. For example, cigarette smoking in public places can negatively impact other people’s health through passive inhalation of smoke. Therefore, obeying smoking bans in public places would be beneficial to all society23. Ideally, the legitimacy of legal authorities and acceptability of laws to people will result in good compliance with all the rules. Encouraging a law-abiding lifestyle, including both non-health and health-related laws, may prepare society for emergency situations such as natural disasters and pandemics24.
Strengths
The PLABPS is a brief scale with 10 items, so it takes little time for individuals to complete. The scale allows researchers from disciplines such as psychology, sociology, criminology, and urban sciences to compare law-abiding behaviors of various community subgroups and their deviations from the average of the general population, so that the correlates of such behaviors can be clarified in each subgroup. In addition, it may provide a useful benchmark for researchers of political sciences and law decision-makers to identify which specific laws are more likely to be accepted and followed by individuals. The association between PLABPS scores and health behaviors need to be confirmed in future studies, and may be useful in developing strategies to promote positive health-related behaviors.
Limitations
There were some limitations to the present study that should be noted. The present study was conducted in one city of one country, and participants were recruited through convenience sampling. These sampling issues may compromise generalizability. Assessing public law-abiding behaviors is conceptually challenging and diversity of public laws throughout the world makes it difficult to cover all aspects of the issue. However, the present study developed a brief scale that consisted of items which are supposed to be legal in most parts of the world. The present study comprised a single population with a moderate size sample of general population. Therefore, it was unable to compare specific population subgroups who have a greater tendency to disobey the law, such as substance addicts, prisoners and individuals with antisocial personality disorder. To the best of the present authors’ knowledge, there is no gold standard test for evaluating law-abiding behaviors. Therefore, the criterion validity of the PLABPS could not be tested. Nevertheless, assessment of known-groups validity confirmed that the scale could discriminate between groups that are known to differ in their law-abiding tendency (i.e., those with or without a university degree). Further cross-country and within-country studies are needed to validate the PLABPS in diverse cultural contexts.
