This paper presents a structural model of the determinants of harsh pa
renting among Mexican mothers. One hundred five mothers (46 from the c
ommunity; 59 referred to agencies for child maltreatment) were recruit
ed from Sonora (Northern) Mexico and interviewed. In this model the us
e of physical punishment was explained by (1) authoritarian parenting
style (mothers' beliefs concerning the effective use of physical punis
hment and mothers' lack of disciplinary skills) and (2) family dysfunc
tion (a latent variable constructed from reports of interspousal viole
nce and the parents' use of alcohol and drugs). In addition, the indir
ect effects of demographic and historical variables on harsh parenting
was included. The findings show that the most important factor influe
ncing the use of physical punishment in these families was authoritari
an parenting style, exerting a significant direct effect on the mother
s' reports of their use of harsh punishment. Family dysfunction had an
indirect effect through parenting style. Some sociodemographic variab
les also indirectly influenced the use of beliefs maternal punishment
It is concluded that cultural beliefs play a major role in parenting w
ithin the framework of Mexican family relations.
