This study was done to compare families of boys or of girls for actor and partner effect of stress, depression and parent-adolescent communication as perceived by mother, father and adolescent on adolescents' suicidal ideation.

Participants were 183 families (104 boys' families, 79 girls' families) who met eligibility criteria. All measures were self-administered. Data were analyzed using SPSS 18.0 and AMOS 18.0 program.

In boys' families, boys' depression and communication with father showed actor effect on boys' suicidal ideation. Boys' stress showed indirect effect on boys' suicidal ideation through communication with father and boys' depression. Mothers' depression showed indirect partner effect on boys' suicidal ideation through boys' depression. In families of girls, girls' depression and stress showed actor effects on girls' suicidal ideation. Girls' communication with mother showed indirect effects through girls' depression. Also girls' stress showed indirect effect through girls' depression. Stress in mothers and/or fathers showed partner effect on girls' suicidal ideation.

To intervene in adolescents' suicidal ideation and promote adolescents' mental health, programs should be developed differently according to gender and based on parent's psychological states.

This study was done to examine actor and partner effect of dementia knowledge, self-efficacy and depression on dementia preventive behavior in elderly couples.

Participants were 115 couples aged 60 years or over who met eligibility criteria. All measures were self-administered. Data were analyzed using SPSS 18.0 and AMOS 18.0 program.

Dementia knowledge in elderly couples showed actor and partner effect on dementia preventive behavior. Self-efficacy in the wife did not have direct effects on dementia preventive behavior, but showed indirect effects through dementia knowledge. Self-efficacy in the husband showed direct effects on dementia preventive behavior and indirect effects through dementia knowledge. Wife's depression had direct actor effect on dementia preventive behavior and indirect effect through self-efficacy and dementia knowledge. Husband's depression did not have direct actor effect on dementia preventive behavior, but indirect effect through self-efficacy and dementia knowledge. Effect size of wives' dementia knowledge, self-efficacy and depression on dementia preventive behavior was larger than that of husbands'. Dementia preventive behavior, dementia knowledge and depression had a mutual effect.

Results indicate that to promote dementia preventive activity in elderly couples, programs should be conducted for both of the couple, but focused differently for wife and husband.
