​When social workers assess a treatment group's patterned behavior, they need to:

A) ​encourage other members to adopt a dysfunctional pattern of behavior.
B) ​identify the current capacity of members to share power and resources.
C) ​identify problem-solving methods that lead to a win-lose solution.
D) ​discourage the culture of forming subgroups within the group.

When assessing a treatment group's patterned behavior, it is important for social workers to identify the current capacity of members to share power and resources. This helps in understanding the dynamics of the group and identifying areas where interventions may be required to address any issues or conflicts. Encouraging dysfunctional behavior, promoting win-lose solutions, and discouraging subgroups within the group are not desirable outcomes for a social worker conducting a group assessment.
