Abstract
Due to changing demographics in Germany and the UK and associated retirement policies, in organisations age diversity is expected to increase. Previous research has suggested that age diversity can impact innovation on different organisational levels. On the individual level increased age is associated with a decline of fluid cognitive abilities, which are relevant for the development of innovative ideas. On the organisational level, conflicts, and age stereotypes have a negative impact on innovation.
To prevent and even reverse the adverse impact of age diversity on innovation, an innovation support scheme for SMEs was developed and piloted in a previously conducted research project in Germany. This scheme included interventions for individuals and leaders. At the individual level, a cognitive ability training was introduced to reduce the decline of fluid cognitive abilities and in turn increase the generation of innovative ideas particularly for older employees. Moreover, a leadership training was introduced, which emphasizes on reducing age stereotypes and associated conflicts and enhance appreciation of age diversity. DINNOS, aims to conduct a Randomized-Controlled Trial (RCT) to evaluate the effectiveness of this innovation support scheme in a sample of SMEs from Germany and the UK. In both countries, we will conduct an RCT involving an experimental- and a waiting-list control group with N=300 SMEs which will be equally divided to both groups. On the individual level we will examine cognitive ability, individual creativity and innovation behaviours as outcomes. Whereas on the organisational level outcomes will consist of self-reported indicators, such as reduced age stereotypes and team innovation as well as objective outcomes such as number of submitted ideas and patents.

Experimental Details
Interventions
Intervention(s)
DINNOS involves two training components, that aim to facilitate leadership behaviours (leadership training component) of SME entrepreneurs and cognitive or intellectual capacities (cognitive training component) of individual employees.

Leadership training:
The leadership training component consists of an elaborated training concept for SME entrepreneurs, which is based on the servant leadership approach. The training will focus on three mechanisms, which have been previously demonstrated to underlie the relation between servant leadership and followers’ creativity and innovation. Namely, the training will expand upon how to satisfy followers’ basic psychological needs, manage task and relationship conflicts within teams, and facilitate a climate of psychological safety. During the training participants will be informed about the specific challenges of high age diversity in teams.

Cognitive training:
The cognitive training component is based upon an integrative set of cognitive exercises, which enhance primary memory and executive processes (e.g. attention) as well as fluid cognitive functioning (e.g. inductive and deductive reasoning), in order to foster individual capacities for creative and innovative performance at work. It will be administered in cooperation with CogniFit (https://www.cognifit.com/#).

Primary Outcomes
Primary Outcomes (end points)
Employees' creative and innovative behaviours, Cognitive abilities.
Primary Outcomes (explanation)
Secondary Outcomes
Secondary Outcomes (end points)
Employees' innovative outcomes
Secondary Outcomes (explanation)
Innovation outcomes will be measured by objective measures assessing whether employees have implemented product, services, or process innovations.
Experimental Design
Experimental Design
The design of the trial is a waiting list-control group design. After an initial baseline data collection, SMEs will be randomly assigned to an experimental and a waiting-list control group. SME-entrepreneurs and employees in the experimental group will receive the ISS (Innovation Support Scheme) consistent of the leadership and cognitive training. Afterwards, another data collection involving both the experimental- and waiting-list control group will take place. This data collection will be used to evaluate the effectiveness of the ISS in the experimental group. Finally, the waiting-list control group will receive the ISS followed by a final data collection to assess the effectiveness of the ISS for the waiting-list control group and the long-term effectiveness for the experimental group.
