Figure ?Figure11 depicts the thriver model. Figure 1 Thriver model of contributing factors to positive development after major life events. The thriver model is a process model that aims to describe how growth after major life events can be facilitated. One consequence of critical life experiences is a process referred to as core belief disruption (Cann et al., 2010). Major life events can question our general assumption of the world and hereby make it necessary to integrate the new experience into existing mental structures. The thriver model suggests that meaning making is a key process to enable integration and mental reorganization for positive and negative life events. Supportive relationships and positive emotions might directly effect the occurrence of growth by creating an emotional and social environment that contributes to positive change processes. Alternatively, they might moderate the direct effect of major life events on growth by fostering positive development that is a direct reaction to the experience. Positive emotions One aspect that distinguishes major life events from daily experiences is the high emotional valence connected to these events. Under stressful situations with positive or negative valence, memory processes are strongly enhanced (Phelps, 2004). These neurological processes increase one's ability to form lasting memories and enhance learning processes (Hu et al., 2007). While positive or negative emotions can facilitate enhanced memory processes (Seng, 2012), research indicates that especially positive emotions are critical for the occurrence of psychological growth (Norlander et al., 2005). In a longitudinal study, Fredrickson et al. (2003) investigated the influence of positive emotions on trauma-related outcomes of the terrorist attacks on September 11th. They found that participants who reported higher levels of positive emotions before the terrorist attacks were more likely to react with resilience or posttraumatic growth afterwards. Fredrickson explains the relation between positive emotion and post-crises growth with a mechanism based on her broaden-and-build theory (Fredrickson, 2004). High prevalence of positive emotions provides the neuronal activation for changes in the brain related to a broadening of thought-action repertoires (Fredrickson, 2004). Positive emotions support coping processes by broadening one's attention, thinking, and behavioral skills (Fredrickson, 2004; Tugade et al., 2004). As a consequence, individuals build long-lasting resources, such as a broader arsenal of coping strategies, deeper relationships, and higher well-being. Hereby, individuals develop critical capabilities to draw from in times of adversity that facilitate posttraumatic growth (Folkman and Moskowitz, 2000; Folkman, 2008).
