Alterations in regulation of affect (emotion) and impulse:Almost all people who are seriously traumatized have problems in tolerating and regulating their emotions and surges or impulses. However, those with complex PTSD and dissociative disorders tend to have more difficulties than those with PTSD because disruptions in early development have inhibited their ability to regulate themselves. The fact that you have a dissociative organization of your personality makes you highly vulnerable to rapid and unexpected changes in emotions and sudden impulses. Various parts of the personality intrude on each other either through passive influence or switching when you're under stress, resulting in dysregulation. Merely having an emotion, such as anger, may evoke other parts of you to feel fear or shame, and to engage in impulsive behaviors to stop avoid the feelings.

Changes in Meaning:Finally, chronically traumatized people lose faith that good things can happen and people can be kind and trustworthy. They feel hopeless, often believing that the future will be as bad as the past, or that they will not live long enough to experience a good future. People who have a dissociative disorder may have different meanings in various dissociative parts. Some parts may be relatively balanced in their worldview, others may be despairing, believing the world to be a completely negative, dangerous place, while other parts might maintain an unrealistic optimistic outlook on life

Changes in Relationship with others:It is especially hard to trust other people if you have been repeatedly abused, abandoned or betrayed as a child. Mistrust makes it very difficult to make friends, and to be able to distinguish between good and bad intentions in other people. Some parts do not seem to trust anyone, while other parts may be so vulnerable and needy that they do not pay attention to clues that perhaps a person is not trustworthy. Some parts like to be close to others or feel a desperate need to be close and taken care of, while other parts fear being close or actively dislike people. Some parts are afraid of being in relationships while others are afraid of being rejected or criticized. This naturally sets up major internal as well as relational conflicts.

Changes in the Perception of Self:People who have been traumatized in childhood are often troubled by guilt, shame, and negative feelings about themselves, such as the belief they are unlikable, unlovable, stupid, inept, dirty, worthless, lazy, and so forth. In Complex Dissociative disorders there are typically particular parts that contain these negative feelings about the self while other parts may evaluate themselves quite differently. Alterations among parts thus may result in rather rapid and distinct changes in self perception.

Complex PTSD consists of six symptom clusters, which also have been described in terms of dissociation of personality. Of course, people who receive this diagnosis often also suffer from other problems as well, and as noted earlier, diagnostic categories may overlap significantly. The symptom clusters are as follows:Alterations in Regulation of Affect (Emotion) and Impulses Changes in Relationship with others Somatic Symptoms Changes in Meaning Changes in the perception of Self Changes in Attention and Consciousness

Dissociative parts of the personality are not actually separate identities or personalities in one body, but rather parts of a single individual that are not yet functioning together in a smooth, coordinated, flexible way. P14

Fear and anxiety affect decision-making in the direction of more caution and risk aversion... Traumatized individuals pay more attention to cues of threat than other experiences, and they interpret ambiguous stimuli and situations as threatening (Eysenck, 1992), leading to more fear-driven decisions. In people with a dissociative disorder, certain parts are compelled to focus on the perception of danger. Living in trauma-time, these dissociative parts immediately perceive the present as being "just like" the past and "emergency" emotions such as fear, rage, or terror are immediately evoked, which compel impulsive decisions to engage in defensive behaviors (freeze, flight, fight, or collapse). When parts of you are triggered, more rational and grounded parts may be overwhelmed and unable to make effective decisions.

Most dissociative parts influence your experience from the inside rather than exert complete control, that is, through passive influence.*In fact, many parts never take complete control of a person, but are only experienced internally. *Frequent switching may be a sign of severe stress and inner conflict in most individuals.

Our inner experience is that which we think, feel, remember, perceive, sense, decide, plan and predict. These experiences are actually mental actions, or mental activity (Van her Hart et al., 2006). Mental activity, in which we engage all the time, may or may not be accompanied by behavioral actions. It is essential that you become aware of, learn to tolerate and regulate, and even change major mental actions that affect your current life, such as negative beliefs, and feelings or reactions to the past to interfere with the present. However, it is impossible to change inner experiences if you are avoiding them because you are afraid, ashamed or disgusted by them. Serious avoidance of you inner experiences is called experiential avoidance (Hayes, Wilson, Gifford, & Roulette, 1996), or the phobia of inner experience (Steele, Van her Hart, & Nijenhuis, 2005; Van her Hart et al., 2006).

Parts of you are phobic of anger and generally terrified and ashamed of angry dissociative parts. There is often tremendous conflict between anger-avoidant and anger-fixated parts of an individual. Thus, an internal and perpetual cycle of rage-shame-fear creates inner chaos and pain.
