Traditional research about identity status has been followed by investigations of identity change that challenge the notion of a general increase in maturity during adolescence while also calling for a more contextualized view on identity processes. This study examines changes in identity measured by the Identity Scale of the Erikson Psychosocial Stage Inventory. In a group of 294 high school students, four different trajectories were found between sophomore and senior years. The authors explored whether relationships with mothers and friends would be associated to identity trajectories. Our results show that a decremental change in identity was related to persistent problems with mothers and friends. For mothers, a lack of communication and for friends, persistent conflicts were related to decremental identity changes.

Satisfaction with sexual activity i.e. sexual satisfaction and the importance of sexuality and affection were analysed using data from the German “Interdisciplinary Longitudinal Study of Adult Development” (ILSE). At three measurement points, 1993–1995, 1997–1998, and 2004–2006 i.e. subjects' ages of 63, 67, and 74 years, participants' reports about their affection and sexual activity were collected. The sample of completed records used for this study consisted of 194 urban non-institutionalised participants, 68% male, all living with partners. Median levels of sexual satisfaction were reported, fluctuating between the measurement points of ages 63 to 74. Between baseline, first and second follow-up no differences were found in levels of sexual satisfaction, though at measurement points age 63 and 67 women were more satisfied than men. When measured at age 74, affection was given a higher priority than sexual activity. Although men and women reported similar priorities, sexual activity and affection were more important for men than for women. Satisfaction within the relationship can be predicted by the importance of affection, but not by that of sexual activity. Our results confirm the thesis of the ‘second language of sexuality’: for humans in their later years affection seems to be more important than for younger individuals.

We investigated the effects of zuclopenthixol on aggressive behaviour in patients with intellectual disabilities by randomly withdrawing it after a 6-week period of open treatment. Of the 49 patients responding to the treatment, 39 took part in a randomised withdrawal trial. The placebo subgroup (n=20) showed more aggressive behaviour as indicated by outcomes observed by external raters on the Modified Overt Aggression Scale than did the continuing subgroup (n=19). The results indicate that discontinuation of zuclopenthixolin this population leads to an increase in aggressive behaviour.
