Inclusion criteria
Inclusion criteria: To be eligible for inclusion, a participant/girl must meet all of the following criteria: 1) Aged 10 to 12 years. 2) Visiting a primary school of RiBA, BLICK op onderwijs, and Scholennetwerk BSI (i.e., collaborative school network). 3) Attending 5th or 6th grade of mainstream upper primary education in academic year 2025/2026 or 2026/2027. 4) Being a cisgender woman or being a transgender woman. 5) Having a good or best friend (being a cisgender woman or being a transgender woman) at the same school. To be eligible for inclusion, a dyad/girls must meet the following inclusion criteria: By lack of an official cut-off score for high co-rumination levels, we will base our inclusion on a distribution-based technique. That is, we will include friendship dyads of which at least one of the two girls, or both girls, have a score above the median co-rumination screening score on the Co-rumination Questionnaire-Short (Hankin, Stone & Wright, 2010). This will result in a sample of the 50% highest scoring girls on co-rumination. Note that a distribution-based technique is a common-used technique to select a high-risk population of clinical significance in the absence of meaningful clinical cut-offs (Loan, Symonds, Vargas-Chanes & Fridley, 2003).
