IDEST: International Database of Emotional Short Texts.

We introduce a database (IDEST) of 250 short stories rated for valence, arousal, and comprehensibility in two languages. The texts, with a narrative structure telling a story in the first person and controlled for length, were originally written in six different languages (Finnish, French, German, Portuguese, Spanish, and Turkish), and rated for arousal, valence, and comprehensibility in the original language. The stories were translated into English, and the same ratings for the English translations were collected via an internet survey tool (N = 573). In addition to the rating data, we also report readability indexes for the original and English texts. The texts have been categorized into different story types based on their emotional arc. The texts score high on comprehensibility and represent a wide range of emotional valence and arousal levels. The comparative analysis of the ratings of the original texts and English translations showed that valence ratings were very similar across languages, whereas correlations between the two pairs of language versions for arousal and comprehensibility were modest. Comprehensibility ratings correlated with only some of the readability indexes. The database is published in osf.io/9tga3, and it is freely available for academic research.

Psychosocial predictors of cannabis use in adolescents at risk.

This research has tested a social disintegration model in conjunction with risk and protection factors that have the power to differentiate relative, weighted interactions among variables in different socially disintegrated groups. The model was tested in a cross-sectional sample of 1082 at-risk youth in Switzerland. Structural equation analyses show significant differences between the social disintegration (low, moderate, high) groups and gender, indicating that the model works differently for groups and for gender. For the highly disintegrated adolescents results clearly show that the risk factors (negative mood, peer network, delinquency) are more important than the protective factors (family relations, secure sense of self). Family relations lose all protective value against negative peer influence, but personal variables, such as secure self, gain protective power.

The Action Plan--a new instrument to collect data on interventions in secondary prevention in adolescents.

It is difficult to draw causal conclusions about the effectiveness of secondary prevention programs for adolescents at risk, when the programs use a variety of different interventions. The Action Plan is an instrument that is designed to make collection of such data possible. This allows calculating different kinds of intervention patterns for each participant and program, which, in combination with outcome measures, gives an estimate of successful vs. less successful interventions. The study compared intervention patterns from 12 different sites in a national intervention program in Switzerland. The program, called supra-f (www.supra-f.ch), started in 1999 and will end in 2005. Results are presented from the ongoing study with approximately 600 adolescents. We calculated effect sizes (ES) to compare interventions with outcome measures. Effect sizes (ES) are presented on well being, coping, self-esteem, delinquency, and substance use (cigarettes, alcohol, cannabis) in relation to intervention packages, risk groups (low, moderate, high), and age (two groups: 11-15 and 16-20 years of age) using data collected from 1999-2002.
