A complex systems perspective on chronic aggression and self-injury: case study of a woman with mild intellectual disability and borderline personality disorder.

The feasibility of daily monitoring in adolescents and young adults with mild intellectual disability or borderline intellectual functioning.

Background: It is unclear whether the limitations of young persons with a mild intellectual disability or borderline intellectual functioning preclude feasibility of the daily diary method.

Method: For 60 consecutive days, 50 participants (M  = 21.4, 56% male) who receive care in an ambulatory, residential, or juvenile detention setting, self-rated both standardised and personalised diary questions through an app.

Exploring the role of emotional and behavioral problems in a personality-targeted prevention program for substance use in adolescents and young adults with intellectual disability.

Background: Adolescents and young adults with a mild intellectual disability or borderline intellectual functioning (MID-BIF) are at risk for problematic substance use and are more likely to have emotional and behavioral problems than peers without MID-BIF. A personality-targeted prevention program called Take it Personal! effectively reduces substance use in adolescents and young adults with MID-BIF.

Aims: The program's effectiveness was examined on its secondary goal: reducing emotional and behavioral problems.

The prevention programme aims to reduce SU (alcohol, cannabis and illicit drugs) among experimental to problematic substance users.
