Clinical Impairment

Aim: The Clinical Impairment Assessment (CIA 3.0) is the most widely used instrument assessing psychosocial impairment secondary to eating disorder symptoms. However, there is conflicting advice regarding the dimensionality and optimal method of scoring the CIA. We sought to resolve this confusion by conducting a comprehensive factor analytic study of the CIA in a community sample ( N = 301) and clinical sample comprising patients with a diagnosed eating disorder ( N = 209). Convergent and discriminant validity were also assessed. Method: The CIA and measures of eating disorder symptoms were administered to both samples. Results: Factor analyses indicated there is a general impairment factor underlying all items on the CIA that is reliably measured by the CIA Global score. CIA Global demonstrated good convergent and discriminant validity. Conclusions: CIA Global is a reliable and valid measure of psychosocial impairment secondary to eating disorder symptoms; however, subscale scores should not be computed.

Background: There has been an increased effort to understand the nature of obsessive-compulsive disorder (OCD) in non-Western cultures. In particular, growing research has examined OCD in China, but there are no comprehensive instruments that measure both OCD severity and heterogeneity for characterizing samples. Aims: A validated, comprehensive measure that could be used in China would provide researchers with a useful instrument for evaluating severity and heterogeneity of OCD in a non-Western culture, allowing researchers to better understand the universal and cultural components that play a role in the nature of OCD. Method: The current investigation presents data on the reliability and validity of a Mandarin translation of the Obsessive-Compulsive Inventory-Revised (CH-OCI) using both a student (n = 1950) and clinical sample (n = 50 patients with OCD; n = 50 patients with anxiety as a comparison group). Results: Results support the factor structure, convergent and discriminant validity, criterion-related validity, test-retest reliability, and internal consistency of the CH-OCI. Conclusions: Validation of the instrument permits researchers and clinicians to measure OCD presentation in Mandarin-speaking samples.

Five Phases

The Faceted Inventory of the Five-Factor Model (FI-FFM) is a comprehensive hierarchical measure of personality. The FI-FFM was created across five phases of scale development. It includes five facets apiece for neuroticism, extraversion, and conscientiousness; four facets within agreeableness; and three facets for openness. We present reliability and validity data obtained from three samples. The FI-FFM scales are internally consistent and highly stable over 2 weeks (retest rs ranged from .64 to .82, median r = .77). They show strong convergent and discriminant validity vis-à-vis the NEO, the Big Five Inventory, and the Personality Inventory for DSM-5. Moreover, self-ratings on the scales show moderate to strong agreement with corresponding ratings made by informants ( rs ranged from .26 to .66, median r = .42). Finally, in joint analyses with the NEO Personality Inventory–3, the FI-FFM neuroticism facet scales display significant incremental validity in predicting indicators of internalizing psychopathology.

The aim of the current study was to analyze psychometric properties of the Short LOI-CV in Spanish community sample. Participants were 914 children and adolescents with mean age of 13.01 years (51.3% males). An EFA yielded a three-factor model representing Obsessions, Compulsions, and Cleanliness dimensions. Both, total score and subscales showed an adequate internal consistency. The Spanish version also exhibited good test-retest reliability and moderate convergent and discriminant validity. The younger participants (from 8 to 10 years) obtained higher means for total score and subscales than older participants (groups 11-13 and 14-18 years). Significant differences related to gender were also observed since males obtained higher means in Compulsions subscale. Despite more research is required, the Spanish version of the Short LOI-CV exhibited promising psychometric results to assess obsessive-compulsive symptoms in community population.

The Impact

This paper describes three studies of the reliability and validity of a newly revised version of the Purdue Posttraumatic Stress Disorder scale (PPTSD-R). The PPTSD-R is a 17-item questionnaire that yields four scores: Reexperiencing, Avoidance, Arousal, and Total. It is highly internally consistent (α = .91), and the scores are relatively stable across time. The PPTSD-R is highly correlated with other measures of PTSD symptomatology and moderately correlated with measures of related psychopathology, providing preliminary support for the measure's convergent and discriminant validity. It reliably distinguishes between groups of people who were and were not traumatized, it is sensitive to the impact of different types of traumatic events, and (within a clinical sample) it discriminates between those who did and did not seek treatment for difficulty coping with the traumatic event being assessed. The PPTSD-R shows promise as a measure of PTSD symptoms in the college population.

Detailed Assessment

The Detailed Assessment of Posttraumatic Stress (DAPS; Briere, 2001) is a comprehensive questionnaire that assesses posttraumatic stress disorder (PTSD) diagnostic criteria as well as peritraumatic responses and associated problems such as dissociation, suicidality, and substance abuse. DAPS scores have demonstrated excellent reliability, validity, and clinical utility, performing as well or better than leading PTSD questionnaires. The present study was an initial psychometric evaluation of the unreleased DAPS (DAPS-2), revised for Diagnostic and Statistical Manual of Mental Disorders–Fifth edition ( DSM-5), in an MTurk-recruited mixed trauma sample ( N = 367). DAPS-2 PTSD scale and associated features scales demonstrated high internal consistency and strong convergent and discriminant validity. In confirmatory factor analyses, the DSM-5 four-factor model of PTSD provided adequate fit, but the leading seven-factor model provided superior fit. These results indicate the DAPS-2 is a psychometrically sound measure of DSM-5 PTSD symptoms.

Antisocial Attitudes

The Empathy (E) scale has been proposed as a theoretically and psychometrically more satisfying alternative to existing self-report measures of empathy. Its four scales (facets) cover both components (cognitive vs. emotional) and both reality statuses (fictitious vs. real-life) of empathy in pairwise combinations. Confirmatory factor analyses of the E-scale in an Austrian community sample ( N = 794) suggested that one prior assumption, namely the mutual orthogonality of these facets, may partly need revision; particularly, the E-scale facets seemed to reflect more strongly differences in the reality statuses than in the components of empathy. Utilizing numerous informative psychological traits, the scale's convergent and discriminant validity were examined. E-scale scores were consistently predicted by sex-related and relationship-related constructs and measures of antisocial attitudes and behavior. Among the Big Five personality dimensions, openness emerged as a major positive correlate of empathy. Sex and age were demographic correlates of E-scale scores (higher in women and the younger). Findings were discussed with regards to the definition and measurement of empathy.

Enhanced Cognitive Behavioral Therapy (CBT-E) is an evidence-based treatment for bulimia nervosa (BN), which can be delivered individually or in a group format. This case study describes a young adult female’s progress through a CBT-E group program at an Australian community outpatient eating disorder service. She completed 20 sessions over 10 weeks. The client was administered measures for eating disorder symptoms, depression, anxiety, stress, stage of change, and clinical impairment at pre- and posttreatment. She improved on global eating disorder symptoms, food restriction, eating concern, and her stage of change. Her weight and shape concerns remained unchanged. Her levels of depression, anxiety, and stress significantly increased after treatment, highlighting the need for concurrent treatment for these comorbidities. These results support the developing literature on the efficacy of CBT-E for BN and describe in detail the progress of an individual, including their progress and challenges within a group intervention.

This study examined the reliability and validity of an expanded version of the Iowa Sleep Disturbances Inventory (ISDI; Koffel & Watson, 2010) in 2 samples (219 college students and 200 psychiatric patients). The expanded ISDI includes the scales of Sleep Paralysis and Sleep Hallucinations. These scales, along with the Nightmares scale, help define a higher order factor entitled Unusual Sleep Experiences. This factor was distinct from the factors of Insomnia and Lassitude that were reported previously. The expanded ISDI showed strong evidence of convergent and discriminant validity with the corresponding interview ratings on a clinician rating version of the ISDI. Mean convergent correlations were .68 in students and .70 in patients. Convergent correlations were significantly higher than discriminant correlations in 99.8% of the 624 comparisons. This study also reports the associations of higher order sleep factors with questionnaire and interview measures of pathological symptoms (e.g., depression, anxiety, dissociation, and schizotypy). The Lassitude factor was specific to dysphoria, whereas the Unusual Sleep Experiences factor was specific to posttraumatic stress disorder (PTSD) and dissociation. Finally, several ISDI scales showed strong evidence of specificity in relation to pathological symptoms; in particular, there were strong associations between (a) ISDI Fatigue and measures of dysphoria, (b) ISDI Nightmares and measures of PTSD, and (c) ISDI Sleep Hallucinations and measures of dissociation.
