Introduction PTSD is a psychological condition that is known to occur as a result of a certain traumatic experience, such as partner violence, kidnapping and hostage situation, physical abuse, neglect in childhood, and concentration camp imprisonment, among others (NIMH, n.d.). The condition is known to produce numerous socioemotional, cognitive, and physical issues. In combination, these issues are known to have a detrimental effect on the individual’s development (Weston, 2014). The following paper identifies developmental issues characteristic for adults with PTSD and describes an intervention expected to address them. Developmental Issues The most common socioemotional behavior associated with the condition is avoidance – the tendency of an individual to deliberately or subconsciously avoid experiences related to trauma. On the most basic level, this behavior can affect decisions regarding visits to certain places or events. In more complex cases, certain types of emotions, feelings, and thoughts can fall within the avoidance range (Boden et al., 2013). The latter constitutes a major lifespan issue due to its potential for disruption of daily routines. For instance, a victim of a particularly traumatizing traffic accident may start avoiding cars and other means of transportation, which, in some scenarios, can introduce social challenges. Another widespread developmental issue is related to disproportional reactivity and arousal. Adults with PTSD are known to experience sleep problems and are more likely to engage in angry behaviors, such as emotional outbursts (Pineles et al., 2013). In addition, individuals with PTSD are more likely to be startled and perceive excessive tension. Unlike the avoidance-related issues, increased arousal and reactivity is rarely tied to specific environmental situations. Instead, it is characterized by prolonged exposure and, over time, accumulates into a feeling of anger and stress, described by the sufferers as “being on edge” (Pineles et al., 2013). As a result, it may become more difficult for an individual to concentrate on relatively simple tasks such as eating or sleeping. The third area of developmental issues impacts the cognitive domain. Adults with PTSD experience difficulties remembering details of a traumatic event, which is commonly considered a psychological defensive mechanism intended to shield them from excessive stress. However, this issue also creates a range of social and emotional aspect of the client’s life. Specifically, a client may feel guilty and blame oneself either for the initial traumatic event or subsequent adverse outcomes associated with it (Alabama State Department of Education, 2017). On a broader scale, these feelings may facilitate dissatisfaction with the surrounding reality. Finally, the loss of satisfaction with enjoyable activities can be observed. At this point, it is important to mention that the occurrence of these issues within a short time does not necessarily constitute a PTSD-related developmental issue. In many cases, people experience the same effects within few weeks after the traumatic event with no long-term consequences, in which case lifespan issues do not manifest afterwards. However, once the duration of the symptoms exceeds one month, they becom
