About This Book
Emotion in Posttraumatic Stress Disorder provides an up-to-date review of the empirical research on the relevance of emotions, such as fear, anxiety, shame, guilt, and disgust to posttraumatic stress disorder (PTSD). It also covers emerging research on the psychophysiology and neurobiological underpinnings of emotion in PTSD, as well as the role of emotion in the behavioral, cognitive, and affective difficulties experienced by individuals with PTSD. It concludes with a review of evidence-based treatment approaches for PTSD and their ability to mitigate emotion dysfunction in PTSD, including prolonged exposure, cognitive processing therapy, and acceptance-based behavioral therapy.
- Identifies how emotions are central to understanding PTSD.
- Explore the neurobiology of emotion in PTSD.
- Discusses emotion-related difficulties in relation to PTSD, such as impulsivity and emotion dysregulation.

Assessment of emotion and emotion-related processes in PTSD

Abstract
This chapter reviews methods for assessing emotions and emotion-related processes in the context of posttraumatic stress disorder (PTSD). We present brief descriptions of emotions including anger, anxiety, fear, guilt, sadness, shame, guilt, and anger and offer recommendations for their measurement. We also review assessment strategies for emotion-related processes that are particularly relevant to PTSD presentations, including alexithymia, anhedonia, anxiety sensitivity, distress tolerance, emotion regulation, and experiential avoidance. All assessment strategies were identified based on the available literature and the frequency of their use with trauma samples. For most constructs, we present recommendations and descriptions for self-report questionnaires although, where appropriate, we also describe lab-based or behavioral measures. Brief psychometric information and administration details are also provided.

Assessment of emotion and emotion-related processes in PTSD
Posttraumatic stress disorder (PTSD) is a complex disorder characterized by intense emotions across several domains, including not only prominent fear and anxiety but also sadness, guilt, and shame. PTSD has also been characterized by emotional numbing and anhedonia (i.e., a loss of interest or pleasure), both of which reflect a diminished experience of positive emotion. Additionally, some research has pointed to emotion-related processes (e.g., emotion regulation and experiential avoidance) as risk factors that may contribute to the onset or maintenance of PTSD following trauma exposure. Key to research and clinical work with these emotions and processes is a thorough assessment of PTSD. There are two psychometrically sound, DSM-correspondent, assessment instruments available from the National Center for PTSD (www.ncptsd.org): the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5; Weathers, Blake, et al., 2013), a structured interview, and the PTSD Checklist (PCL-5; Weathers, Litz, et al., 2013), a self-report questionnaire. For clinicians and researchers who also wish to thoroughly assess the emotions and emotion-related processes that accompany or contribute to PTSD or have implications for psychotherapy, this chapter offers insight into the available, research-supported assessment options. Herein, we briefly review key emotions and emotion-related processes that have relevance for PTSD and recommend assessment instruments for each domain based on the available research. The recommended measures presented in this chapter do not reflect an exhaustive list, but instead represent some of the measures with the most support in the published literature.
Assessment of emotions in PTSD
We begin with the assessment of emotions in the context of PTSD. In this section, we include emotions that are either components of the diagnostic criteria for PTSD or frequently present alongside PTSD. In general the most well-established assessment methods for most constructs are questionnaires. All recommended measures appear in Table 1.

Anger
Individuals with PTSD frequently report problems with anger, ranging from the manifestation of high anger emotional states to behavioral dyscontrol in the form of aggressive, violent, or risky behaviors (American Psychiatric Association, 2000, 2013). Heightened irritability and angry outbursts are frequent features of the disorder and have been implicated among some trauma survivors as the most impairing feature of PTSDâs emotional landscape (e.g., Biddle, Elliott, Creamer, Forbes, & Devilly, 2002; Rosen, Adler, & Tiet, 2013). In a metaanalytic review of anger expression in PTSD, Olatunji, Ciesielski, and Tolin (2010) examined over 2000 patients with anxiety disorders across 28 studies and found that anger was uniquely heightened in patients with PTSD relative to other anxiety disorders, where high levels of irritability were also found. Moreover, results from the study indicated that individuals with PTSD distinctively struggle with the expression and control of anger, suggesting that problems with anger may be part of a broader network of emotional dysregulation and behavioral dysfunction.
The eroding effects of anger on interpersonal relationships (Kubany, Bauer, Muraoka, Richard, & Read, 1995) and links between anger and further negative outcomes (e.g., comorbidity (Gonzalez, Novaco, Reger, & Gahm, 2016) and aggressive/violent behavior (Jakupcak et al., 2007)) suggest that the assessment of anger in clinical contexts is necessary for comprehensive trauma care. Researchers studying trauma populations would also benefit from further investigation of this important emotional feature of PTSD emotional profiles. Additionally, certain populations of trauma survivors have been more frequently studied (e.g., combat veterans) than others, suggesting that there are unique gaps in the literature that warrant greater inquiry to understand the contextual role of anger across trauma types and populations.
Like other measures intended to capture emotional expression, measures of anger are frequently conceptualized in terms of state anger (e.g., specific, cued anger responses) and trait anger (e.g.,...
