This paper presents a study that was developed with a sample of middle and high school students of the 3rd cycle of a Portuguese school, with an average age of 13.52 years (SD = 0,96) and an almost equal distribution in terms of sex (73 males vs. 70 females) and schooling (44 in the 7th year, 49 in the 8th year and 50 in the 9th year). The results show a prevalence of Observation Behaviour in the Victimization Scale and School Aggression and the dimension Satisfaction with Family in Satisfaction Scale Social Support. It was found that 37% of the sample has experienced Cyberbullying and 59% have had knowledge of Cyberbullying situations, which correlates positively with the Observation and Victimization behaviours of Victimization Scale and School Aggression.

The objective of the study conducted was to detect differences in social skills and satisfaction with social support in social activism (online and/or offline). Quantitative, cross-sectional study was conducted with 210 participants, mostly women (n = 154; 73.3%), mean age 31.19 years (SD ± 11.62). We used a socio-demographic questionnaire, a questionnaire on social activism, the Social Support Satisfaction Scale and the Social Skills Inventory for data collection. Statistically significant differences were detected among supporters of social causes, presenting these lower scores on "friend satisfaction" and higher scores on the "self-exposure to unknown or new situations" factor when compared to who do not support social causes offline. It was also verified that individuals belonging to Facebook pages and/or groups and those who support online/offline causes, when compared with their counterparts, scored better on the factors "conversation and social skills" and "self-exposure to strangers and to new situations".
