Abstract When studying therapeutic alliance, researchers typically use data with a ‘one-with-many’ (OWM) nested structure in which each therapist (‘one’) treats several clients (‘many’). The OWM structure offers the opportunity to assess the interdependence in dyadic therapeutic alliance data by disentangling three components: (1) the client’s tendency to generally rate the alliance with his therapists (‘client perceiver’ component); (2) the client’s rating of the unique alliance with his therapist (‘client relati…

Progression-based game elements such as player progression, which allows one's character to level up and grow in strength or difficulty progression, which provides users with increasingly difficult challenges as they progress in their task are widely used techniques in contemporary gamification design. However, few studies have been carried out to examine in-depth their influence on user experiences and motivation. In this study, two experiments were conducted: the first, a between subject experiment involving 78 …

PSMA PET/CT for assessing treatment response at predefined time points was superior to PSA-based response for predicting overall survival in mCRPC patients treated with androgen receptor-targeted agents and chemotherapy. PSMA PET/CT showed the ability to detect disease progression earlier than PSA levels, which can affect treatment decisions and has the potential to improve patient outcomes. We recommend further research to validate these findings in larger patient cohorts, to extend the number of treatments, and …

Abstract The therapeutic alliance is considered to play an important role in youth treatment. The commonly used versions of the Working Alliance Inventory (WAI) are based on Bordin’s three-dimensional alliance model. However, previous psychometric studies of the WAI did not find this three-dimensional structure in youth psychotherapy. These earlier findings may indicate different perceptions of the alliance by adolescent versus adult patients, but may also be due to methodological shortcomings. The current study a…

This study examined whether the relationship between friends' drinking norms and male adolescents' alcohol use is moderated by performance-based peer influence susceptibility. Seventy-three male adolescents (M = 17 years) from three schools in the Netherlands were exposed to the drinking norms of "peers" (electronic confederates) in a chat room experiment. These peers were either popular or unpopular, and conveyed pro- or anti-alcohol norms. Peer influence susceptibility was defined as the change in adolescents' a…
