A negative t-value (-3.22) indicates that the mean of the experimental group (family therapy condition) was lower than the mean of the control group.

Therefore, the correct interpretation is that the family therapy condition had a mean that was reliably more than the mean of the control condition, as the significance indicates a reliable difference in the opposite direction of the negative value.
