Abstract

A scoping review is a method which is often applied in the systematic review arena. Its aim is to map existing literature in a specific area. Carrying out a scoping review entails dealing with a number of methodological questions that arise during the review. In this paper, we go into the way in which these issues were contemplated upon and dealt with. We particularly focus on how to deal with the critical appraisal of literature (and the use of the outcome of this appraisal in terms of in- or exclusion criteria) and its effects on the contents and outcome of the review. This implies that we will report on the result of a sensitivity analysis. A second methodological issue that is focused on is how to make a review that considers multiple (qualitative, quantitative and mixed methods) designs and how to handle the different types of results that were derived from each method. We conclude by considering the pros and cons of including inadequately reported studies and plea to inform readers on the quality of literature that was included.

Fußnoten
1
Currently policing is not solely executed by the public police anymore. Instead, multiple actors (e.g. private police, inspectorate services, citizens) are engaged in policing activities (e.g. order maintenance, law enforcement, crime investigation). The term plural policing refers to the fact that policing services are delivered in the public, semi-public and private domain by a complex of public and private bodies and agencies (for results of the review, see Boels and Verhage 2016). The aim of our scoping review was to identify the literature on the dangers of plural policing and on the impact of plural policing on core police tasks.
 
2
Some of these have been thoroughly explained such as content analysis (Finfgeld-Connett 2013), meta-ethnography (Lee et al. 2015) and thematic synthesis (Cruzes and Dyba 2011).
 
3
For us, empirical research implies that the publication needed to refer to newly collected data. Empirical was defined as “established through observation what is happening in reality” (Baarda et al. 2009). This implies data gathering, through either qualitative, or quantitative methods, or a combination of both.
 
4
Blurring AND boundaries OR lines; extended policing family; new security complex; policing AND commodification; policing AND diversification; policing AND fragment*; policing AND hybrid; policing AND network; policing AND third party; polic* AND plural; polic* AND complex; polic* AND function.
 
5
Toezicht; handhaving; netwerkstructuur; politie AND plural*; plural AND policing; politiefunctie; veiligheid AND fragmentering; veiligheidscomplex; veiligheidshandhaving; vervagende AND grenzen. We chose to include English key terms to identify studies in Dutch, as we found that these terms are sometimes also used in Dutch publications.
 
6
In addition, we registered the dates of search, time span of literature (in some databases, such as the Campbell Library, studies were not accessible as from 1990, but only for instance as from 2003), places of keywords search (title, abstract full text) plus reason why not searched in title and extra search features (if applicable).
 
7
Three publications were based on the same empirical data, so in fact two studies used mixed methods.
 
8
For examples we refer to Dixon-Woods et al. (2004), Hannes et al. (2010), Popay et al. (1998), Spencer et al. (2003).
 
9
Meaning that the methods used are mentioned by the authors in the introduction and/or methods-section.
 
10
Whereas one study for instance focused on the evaluation of partnerships between the police and local groups engaged in policing in fragile African states, another one focused on the impact of civilian policing on the legitimacy of the public police, the extent of public support for civilian policing and their impact upon crime reduction in the UK.
 
11
These four criteria are included in different appraisal checklists and tools, such as the Critical Appraisal Skills Programme (CASP) and the evaluation tool for qualitative studies (ETQS) (Carroll et al. 2012).
