“…Sykes (1958) claimed that the core “pains of imprisonment” that is, the loss of freedom, lack of supplies (e.g., hygiene supplies, foods, medicines), deprivation of (heterosexual) romantic relationships, and the isolation from outside community can have a strong impact on how offenders behave in correctional institutions. Studies found lack of supplies increased risk of theft-related bullying (Guo et al, 2019; Hassan et al, 2020), and sexual deprivation can be linked to sexual bullying in correctional institutions (Banbury et al, 2016; Carr et al, 2020) . Researchers agreed that some features of the institution generate enormous pressure that may increase the risk of bullying or other forms of aggressive behavior (Adams & Ireland, 2017; Ireland et al, 2016; Sekol et al, 2021), but not limited to these five Sykes’s deprivations.…”
