Perceived poor maternal care, maternal overprotection, and maternal overcontrol are associated with hoarding in women with obsessive-compulsive disorder (OCD), a recent study found. Parenting dimensions, however, are not related to hoarding in men. Researchers evaluated included 894 adults diagnosed with DSM-IV OCD who had participated in family and genetic studies of OCD. They found:

• In men, there were no significant differences between hoarding and non-hoarding groups in maternal or paternal parenting scores.
• In women, the hoarding group had a lower mean score on maternal care (23.4 vs 25.7); a higher mean score on maternal protection (9.4 vs 7.7); and a higher mean score on maternal control (7.0 vs 6.2), compared to the non-hoarding group.
• Women who reported low maternal care/high maternal protection had significantly greater odds of hoarding compared to women with high maternal care/low maternal protection.
