I don't think strict is at all synonymous with "Tiger Mother," though I'd guess Tiger Mothers are very much a subset of strict mothers. I expect "strictness" is something of a proxy for things like inculcating self-control, delayed gratification, and limit setting, while smallish effect size could be because the reverse side of the "strictness" coin might be a proxy for less good (potentially borderline abusive) things.
