Randomization description
The statistical population of the present study will consist of all aggressive fifth-grade male students in Ahvaz city who are studying in the academic year 2025–2026. In this type of effectiveness study, a two-stage approach is usually used: in the sample selection stage, convenience sampling will be employed. After selecting a sample of 40 participants based on the study’s inclusion and exclusion criteria, the participants will be randomly assigned to two groups: “Positive Thinking Skills Training” (intervention group) and “Waitlist” (control group). Randomization will be carried out using variable block randomization with block sizes of 4 and 6 by an independent statistician who is not involved in the implementation process. The random allocation list will be generated using the RAND function in Excel and then placed in opaque, sealed, and numbered envelopes so that the researcher and participants will not be aware of the allocation sequence (allocation concealment). Opening the envelope and informing each participant of their assigned group will be done only when each participant enters the study. To ensure the equivalence of baseline variables (such as aggression level and age), their distribution in the two groups will be examined in the statistical analysis phase.
