However, the evidence for its efficacy published thus far should be regarded as preliminary. AIMS To compare the effectiveness of DBT with treatment as usual for patients with BPD and to examine the impact of baseline(More)

Recurrently depressed patients (N = 187) currently in remission following various types of treatment were randomized to treatment as usual, including(More)
BACKGROUND The Patient Health Questionnaire-9 (PHQ-9) has been widely used in research and clinical settings. To be able to attribute differences in PHQ-9 scores between groups with different cultural backgrounds to differences in the level of depression, the instrument has to possess measurement invariance. METHODS Data from the Apollo-D study were used.(More)
OBJECTIVE Problematic alcohol use is the third leading contributor to the global burden of disease, partly because the majority of problem drinkers are not receiving treatment. Internet-based alcohol interventions attract an otherwise untreated population, but their effectiveness has not yet been established. The current study examined the effectiveness of(More)
