Die Arbeit befasst sich theoretisch und empirisch mit der so genannten Public Service Motivation (PSM) und ihrem Zusammenhang zu anderen psychologischen Motivationstheorien. Die Public Service Motivation geht davon aus, dass öffentlich Beschäftigte unter anderem dadurch motiviert sind, dass sie in ihrer Arbeit einen Dienst am Gemeinwohl sehen. Auf Basis einer empirischen Erhebung konnte dieses Konstrukt auch für Beschäftigte in Deutschland nachgewiesen und der Einfluss soziodemographischer Variablen bestätigt werden. Darüber hinaus gibt die Arbeit erste Hinweise auf Zusammenhänge zu verschiedenen Prozesstheorien der Motivation. Empirisch zeigt sich vor allem zur Gleichheitstheorie und dem darauf aufbauenden Equity Sensitivity Construct ein starker Zusammenhang. / This thesis theoretically and empirically addresses the construct of Public Service Motivation (PSM) and its relationship to other psychological motivation theories. The concept of Public Service Motivation states that employees working in the public sector are primarily motivated by serving the common good. Based on an empirical study this construct was applied to public employees in Germany. Moreover the thesis collects evidence for the relationship between Public Service Motivation and process theories of motivation. As a key result, strong correlations were found between the PSM and the Equity Sensitivity Construct, a modification of equity theory.

Experience, expertise, but also self-confidence and attitudes towards computer technology play an important role in how people interact with computers, especially when problems arise (cf. Janneck, Vincent-Höper, & Ehrhardt, 2013). In this regard, attribution theory is a promising approach to explain general types of user behavior. Attribution theory deals with the causal explanations people find for things happening around them, and also with the extent of control people feel they have over external events. Attribution styles have a considerable influence on motivation, behavior, and emotions (Weiner, 1985; Abramson, Seligman, & Teasdale, 1978). While originating in social psychology, attribution theory is also applicable to computer-related experiences. Recent research found distinct computer-related attribution styles (Niels & Janneck, 2015). Moreover, a study has shown that users with more unfavorable (e.g. low sense of control) attribution styles are less motivated in handling computer issues – such as breakdowns or learning to use new features – than users with more favorable attribution styles (Niels & Janneck, 2017). These results raise the question which specific measures are appropriate to specifically support users with less favorable attribution styles with the intention to increase their motivation to master computer applications.
