Results indicated that high mother-reported maternal acceptance significantly and marginally reduced the positive relation between adolescent-reported threat to self appraisals and mother--reported adolescent externalizing and internalizing problems 6 months later. The pattern of interactions showed a protective-enhancing effect of maternal acceptance, in which high levels of a protective factor allowed youth to engage with the stress so that fewer mental health problems occurred at higher levels of risk. Positive emotions generated through contact with highly accepting mothers might counter negative emotions related to high threat to self appraisals, and promote a return to healthy physiological functioning after exposure to stressors. Highly accepting mothers might divert adolescents’ attention from distressing events, which prevents preoccupation with divorce-related stressors from developing into maladaptive coping styles that increase vulnerability to mental health problems. It is also possible that adolescents with high threat appraisals who have highly accepting mothers are more likely to seek support from their mothers and less likely to seek support from other adolescents who may not be well equipped to provide support, whereas adolescents who do not have highly accepting mothers might rely on their peers to meet their needs for support or assistance.
