A number of recent studies have implicated that incongruent use of hormonal contraceptives (HCs) negatively affects various aspects of women's romantic relationships. It has been suggested that women with incongruent HC use (a discrepancy in HC use status between when they first met their current partner and the time of study participation) report less sexual satisfaction and higher jealousy scores compared to women with congruent HC use. A simil…
No Evidence for Long-Term Causal Associations Between Symptoms of Premature Ejaculation and Symptoms of Anxiety, Depression, and Sexual Distress in a Large, Population-Based Longitudinal Sample
Premature ejaculation (PE) is one of the most common male sexual complaints, but its etiology is unclear. Psychological problems, such as symptoms of anxiety and depression, have traditionally been seen as causal or maintaining etiological components of PE, and previous cross-sectional studies have found weak positive associations between them. The aim of the present study was to test possible causal pathways over time between PE and symptoms of …

A Large-Scale Evaluation of the KiVa Antibullying Program: Grades 4–6
This study demonstrates the effectiveness of the KiVa antibullying program using a large sample of 8,237 youth from Grades 4–6 (10–12 years). Altogether, 78 schools were randomly assigned to intervention (39 schools, 4,207 students) and control conditions (39 schools, 4,030 students). Multilevel regression analyses revealed that after 9 months of implementation, the intervention had consistent beneficial effects on 7 of the 11 dependent variables…
Counteracting bullying in Finland: The KiVa program and its effects on different forms of being bullied
In 2006, the Finnish Ministry of Education mandated our research group to develop an antibullying program for comprehensive schools. The new program, KiVa, includes both universal and indicated actions to reduce bullying. The present study reports the effects of KiVa on nine different forms of being bullied in a sample of 5,651 fourth to sixth graders from 78 schools (39 intervention, 39 control). The findings showed positive effects on each form…
