The research team of Laurence Seematter-Bagnoud is one of the three award winners of the "Qualité de vie 65+" 2018 prize. Its reserch project "Engagement social des seniors et qualité de vie : une étude par méthodes mixtes" (seniors’ social involvement and quality of life: a mixed methods study) aims to examine the association between social involvement and quality of life within the framework of the Lausanne Cohorte 65+ study.


The «Qualité de vie 65+» 2018 Prizes will be awarded on the occasion of the Rendez-vous Leenaards âge & société.

This event, led by Blaise Willa (chief editor of générations), will take place on Tuesday 27 November 2018 at 4.30 pm, in Pully. Open to all, upon registration at :


Thematic and hypothesis

Getting involved in social life can be expressed in various ways: pursuit of a professional activity, involvement in voluntary activities, or also providing help within the family circle or neighbourhood. Whatever its shape, social involvement is an occasion to use or transfer competences and skills. Seniors deem it a substantial dimension of their quality of life. However, few studies have considered the modalities that may make this involvement more or less favourable to quality of life.

The hypotheses formulated within the framework of this study are that social involvement influences quality of life positively and, on the other hand, that the end of this involvement, sometimes linked with the activity’s pressures, is a quality of life negative factor. 


This study – conducted within a sample of approximately 2000 Lausanne seniors living at home and participating to the Lausanne cohorte 65+ (Lc65+) study – is based on mixed methods. First, quantitative analyses will examine the association between the evolution of social involvement (measured in 2011 and 2016) and the evolution of quality of life. Then, discussion groups with voluntary participants will enable the investigation of the mechanisms by which social involvement influences quality of life.

Expected results

The results of this research project will foster the promotion of social involvement among seniors that is carried out by field actors. They also aim to steer the framework conditions and modalities of paid and voluntary work, thus removing the barriers identified, and providing answers to the wishes formulated by the participants.
