Inter-twin and parent-twin relationships and mental health:a study of twins from adolescence to young adulthood
Abstract The sample consisted of 419 twins, born in 1965–1973, from Northern Finland who had been followed at ten-year intervals, at 2–10 years, 12–20 years and at 22–30 years of age. Data on psychosomatic symptoms, parent-twin and inter-twin relationships were elicited, and twins completed the Chil...

Middle adolescence appeared to be the most difficult phase of puberty for twins as far as depressive and psychosomatic/somatic symptoms were concerned. When different twin pairs were evaluated separately, the males of opposite-sex twin pairs seemed to be in the most favourable position, particularly in late adolescence, as they reported least depressive symptoms. Depressive and psychosomatic symptoms were evaluated in relation to parental preference among young adult twins. Parental preference was evaluated in two directions: which one of the parents was reported to feel as being closer to the twin — experienced parental preference evaluated by the twin, and which one of the parents the twin felt closer to — twin’s own preference. Those males who were equally close to both parents (experienced parental preference) had least total depressiveness, while females in intermediate situation had the highest self-confidence and least anhedonia and nervousness. According to twins’ own preference, twins who felt equally close to both parents had least total depressiveness and anhedonia. The intermediate position seems to be the best alternative, as these twins had the least symptoms. Psychosomatic and depressive symptoms were evaluated in relation to co-twin dependence in young adult twins. MZ twins, especially MZ females, reported most often co-twin dependence at all ages.
