Web-based self-help interventions for coping with prolonged grief have established their efficacy. However, few programs address recent losses and investigate the effect of self-tailoring of the content. In an international project, the text-based self-help program LIVIA was adapted and complemented with an Embodied Conversational Agent, an initial risk assessment and a monitoring tool. The new program SOLENA was evaluated in three trials in Switzerland, the Netherlands and Portugal. The aim of the trials was to evaluate the clinical efficacy for reducing grief, depression and loneliness and to examine client satisfaction and technology acceptance. The talk will present the SOLENA program and report results of the Portuguese and Dutch trial as well as preliminary results of the Swiss RCT. The ongoing Swiss trial compares a standardised to a self-tailored delivery format and analyses clinical outcomes, the helpfulness of specific content and the working alliance. Finally, lessons learned in the development and evaluation of a web-based self-help intervention for older adults will be discusses.

Interactions between romantic partners may be disturbed by problematic mobile phone use, i.e., phubbing. Research shows that phubbing reduces the ability to be responsive, but emotional aspects of phubbing, such as experiences of anger and loneliness, have not been explored. Anger has been linked to partner blame in negative social interactions, whereas loneliness has been associated with low social acceptance. Moreover, two aspects of partner responsiveness, understanding and validation, refer to the ability to recognize partner’s perspective and convey acceptance of their point of view, respectively. High understanding and validation by partner have been found to prevent from negative affect during social interaction. The impact of understanding and validation on emotions has not been investigated in the context of phubbing, therefore we posit the following exploratory hypotheses. (1) Participants will report higher levels of anger and loneliness on days with phubbing by partner, compared to days without; (2) understanding and validation will moderate the relationship between phubbing intensity and levels of anger and loneliness. We conducted a daily diary study over seven days. Based on a sample of 133 participants in intimate relationships and living with their partners, we analyzed the nested within and between-person data using multilevel models. Participants reported higher levels of anger and loneliness on days they experienced phubbing. Both, understanding and validation, buffer the relationship between phubbing intensity and negative experiences, and the interaction effects indicate certain nuances between the two constructs. Our research provides a unique insight into how specific mechanisms related to couple interactions may explain experiences of anger and loneliness.
