What is a major criticism of Daniel Levinson's (1978) work that found midlife men had feelings of meaninglessness, turmoil and confusion, dissatisfaction and disappointment with work and family life, and fear of aging and death?

The major criticism is he used a small sample size to arrive at his Theory.

Explanation:

1) First he propounded his theory based on result of experiment he carried out on a group of 40 men only, and his work with women was carried out years later and with a small sample as well.

2) He overstated the consistency and generality of the patterns he found in the samples he used to derive his theory

3) For some people, the evidence for widespread midlife crisis is lacking and, for most people, the passage into middle age is relatively rewarding(tranquil),

most feel younger than they actually are when they approach middle adulthood.

4) the myth of a midlife crisis is perpetuated by society, i.e. it is usually perceived as a society sees it.

5) I some cultures, middle age is not even considered a separate period of life stages.
