Final answer:
The question asks about whether parents overestimated, underestimated, or accurately assessed the strength of their teen's relationships, which can't be directly answered without a specific study or context. Research shows that perceptions can differ between parents and teens due to various factors, and communication is key to addressing these differences.
Step-by-step explanation:
Normally, such findings would come from a psychological or sociological study where the results could vary depending on the group studied, how the data was gathered, and the parameters of the study. Without specific context from a study, one can only speculate about the relationship dynamics at play.
In general, research in psychology and social studies has indicated that there can be discrepancies in perceptions between parents and teens regarding different aspects of the teen's life. For example, parents might overestimate the strength of their teen's relationships because they perceive their child's interactions in a more positive light or due to a bias that stems from their emotional connection. Conversely, they might underestimate those relationships if they are not fully aware of their teen's social dynamics or the depth of their online interactions. In any case, it's essential for communication and understanding in the parent-teen relationship for both parties to discuss and reflect on these perceptions.
