Final answer:
Parenthood is not always associated with an increase in marital satisfaction. There can be positive effects on well-being in the long run, but declines in satisfaction over time are also possible.
Step-by-step explanation:
The statement that parenthood is often associated with an increase in marital satisfaction is false.
Research suggests that while raising children can be stressful, parents may experience positive effects on their well-being in the long run, especially when adult children have a positive effect on parental well-being. However, there can be declines in marital satisfaction over time as individuals may find that their values and life goals no longer align with those of their spouse.
It is important to note that every family is unique, and the impact of parenthood on marital satisfaction can vary from couple to couple.
