Using summated scale scores to make group comparisons is only meaningful if one can assume that the scale measures attribute in the same way in each of the groups involved in the comparison. This assumption is called measurement invariance. This contribution discusses the use of modern statistical measurement models to test this assumption and to verify the consequences of a possible violation for the comparison of group means. In the empirical part of the contribution the authors illustrate their account by examining whether a scale assessing avoidance behavior – commonly used in fear of crime research – is invariant across gender and age groups.

Gender, in criminological research, often refers to women. Although ‘masculinities’ and crime have been intertwined internationally for more than two decades, this isn’t so for Dutch research. Based on this international critique, this article introduces the masculinities approach in Dutch penology. Prisons are generally considered as hypermasculine settings (Toch, 1998), but this hypothesis is seldom explored within a gender framework. Nevertheless, ‘doing masculinity’ is an important coping strategy for male prisoners (Jewkes, 2005). This gap is tackled on two levels: (1) the conceptualization of ‘hegemonic masculinity’ and (2) a critical, masculinity-oriented analysis of the existing knowledge on prison life, prison culture and prison hierarchy. It aims to tackle prison masculinity stereotypes, since traditional penal insights aren’t necessarily valid from a gender point of view (Evans & Wallace, 2008). Therefore, we conclude by analyzing the value of masculinity studies for penology.
