The Ottawa Self-Injury Inventory (OSI) is a self-report measure that offers a comprehensive assessment of nonsuicidal self-injury (NSSI), including measurement of its functions and addictive features. In a preliminary investigation of self injuring college students who completed the OSI, exploratory analysis revealed four function factors (Internal...

Nonsuicidal self-injury (NSSI) is an issue primarily of concern in adolescents and young adults. Thus far, no single NSSI self-report measure offers a fully comprehensive assessment of NSSI, particularly including measurement of both its functions and potential addictive features. The Ottawa Self-Injury Inventory (OSI) permits simultaneous assessme...
Article
Purpose: Non-suicidal self-injury (NSSI) has been recognized as a significant mental health problem in adolescence with high prevalence rates. To date, there are few studies that compare rates of adolescent NSSI between different countries. Thus far no prevalence rates of adolescent NSSI have been reported for Austrian or Swiss community samples....
Article
During the potentially tumultuous adolescent period, non-suicidal self-injury (NSSI) and suicide attempts are relatively common, particularly amongst youth who present to mental health services. These phenomena frequently co-occur but their relationship is unclear. This study evaluated clinical data from 468 youth between the ages of 12 and 17 year...
Article

Nonsuicidal self-harm includes cutting, scratching, burning and minor overdosing. There have been few studies that have examined the rate of self-harm and mental-health correlates among community-based youth. We performed a population-based study to determine the prevalence of nonsuicidal self-harm, its mental-health correlates and help-seeking beh...
Article
Clinical experience suggests the use of alternative remedies, such as St. John's Wort (SJW), in adolescents with affective disorders is increasing. In view of the paucity of documented, well-established, and safe antidepressant medications for children and adolescents, it was important to investigate the potential usefulness of SJW in adolescents w...
Article
Self injurious behaviour is not uncommon in depressed adolescents while little is known about effective treatments for this behaviour in this age group. The objective of this article is to illustrate the development and initial pilot of groups for adolescents who self injure and their parents. Articles and texts derived from a literature search of...
Article

Repetitive self-injurious behavior (SIB) is frequently seen in depressed adolescents. In addition to it providing relief for dysphoric symptoms there is evidence of an addictive component to this behaviour. Because auricular acupuncture (AA) has been shown to be effective as an adjunct treatment to cocaine dependence, we wished to test the feasibil...

The incidence of self-injurious behavior (SIB) in adolescent psychiatric inpatients has been reported to be as high as 61%, yet few data exist on the characteristics and functional role of SIB in this population. Because of the repetitive nature of SIB and its potential to increase in severity, features of SIB and its specific reinforcing effects w...
Article
This 6-month open-label study evaluated the efficacy, tolerability, and safety of sertraline in 21 adolescent psychiatric outpatients, ages 12 to 18 years, diagnosed with major depressive disorder (MDD, n = 13) or dysthymic disorder (DD, n = 8). Both groups showed clinically significant improvements on the Hamilton Depression Scale (HAM-D), Hamilto...

In the mouse forced swimming test (FST) pretreatment with a subactive dose of lithium (1 mEq/kg), given IP 45 min before the test, facilitated the antidepressant activity of iprindole, fluoxetine, and moclobemide (given IP 30 min before the test). These antidepressants (ADS) were not active alone in the FST in this study. Moreover, when subactive l...
Article
The role of the neuropeptide cholecystokinin in schizophrenia has been widely explored because of its modulating action on midbrain dopamine neurons. The recent discovery of more specific receptor subtype cholecystokinin antagonists should be considered as potential treatment for schizophrenia with fewer side effects. This paper reviews cholecystok...
