Psychometric analyses of the Clinician-Administered PTSD Scale (CAPS)--Bosnian translation

Methods for assessing psychological distress in culturally diverse populations are not firmly established. This study was designed to examine the psychometric properties of the Bosnian translation of the Clinician-Administered PTSD Scale (CAPS; D. D. Blake, F. W. Weathers, L. M. Nagy, D. Kaloupek, G. Klauminzer, D. Charney, et al., 1995) in a Bosnian refugee sample. The authors interviewed 115 help-seeking Bosnian refugees with the CAPS-Bosnian translation to examine its internal consistency and convergent validity, and to provide an assessment of its factor structure. This study demonstrated optimal fit with a 2-factor model of posttraumatic stress disorder (PTSD); the authors also found high reliability with a coefficient alpha of 0.92 and strong convergent validity with instruments measuring depression, anxiety, and levels of psychosocial functioning. Future directions for the assessment of PTSD in cross-cultural populations are discussed.     

Depressive personality: reliability, validity, and relation to dysthymia

The reliability and validity of Schneider's (1958) construct of depressive personality was evaluated in a sample of 177 outpatients, who were administered structured diagnostic and family history interviews, an extensive battery of inventories, and a 6-month follow-up assessment. The criteria for depressive personality had moderate to good interrater reliability, internal consistency, and test-retest stability, and the assessment of depressive personality traits was not influenced by patients' clinical states. In addition, preliminary support for the convergent and discriminant validity of the depressive personality construct was obtained. Although there were significant relations between the depressive personality and Diagnostic and Statistical Manual of Mental Disorders (3rd ed. and rev. 3rd ed.; American Psychiatric Association, 1980, 1987) diagnoses of dysthymia, the depressive personality was not entirely subsumed by existing mood disorders.     

Test-retest reliability and construct validity of the Helplessness, Hopelessness, and Haplessness Scale in patients with anxiety disorders

In a sample of 100 Turkish psychiatric patients with diagnoses of anxiety disorders, Lester's Helplessness, Hopelessness, and Haplessness inventory had moderate estimates of internal consistency, test-retest reliability, and construct validity.     

Development and validation of the Eating Disorder Diagnostic Scale: a brief self-report measure of anorexia, bulimia, and binge-eating disorder

This article describes the development and validation of a brief self-report scale for diagnosing anorexia nervosa, bulimia nervosa, and binge-eating disorder. Study 1 used a panel of eating-disorder experts and provided evidence for the content validity of this scale. Study 2 used data from female participants with and without eating disorders (N = 367) and suggested that the diagnoses from this scale possessed temporal reliability (mean kappa = .80) and criterion validity (with interview diagnoses; mean kappa = .83). In support of convergent validity, individuals with eating disorders identified by this scale showed elevations on validated measures of eating disturbances. The overall symptom composite also showed test-retest reliability (r = .87), internal consistency (mean alpha = .89), and convergent validity with extant eating-pathology scales. Results implied that this scale was reliable and valid in this investigation and that it may be useful for clinical and research applications.     

The perceived support network inventory

The development and psychometric investigation of the Perceived Support Network Inventory (PSNI), a measure of perceived social support, is described. A group of 146 introductory psychology students participated in a test-retest study design that collected reliability, internal consistency, and construct, convergent, and discriminant validity data on the scale. In addition, a contrast group of 28 Counseling Center clients was administered the PSNI. Test-retest reliability of the PSNI total score and subscale scores ranged from .72 to .88. Internal consistency for the PSNI was .77. Construct validity estimates ranged from .21 to .57. Convergent validity estimates varied from -.25 to .20. Discriminant validity estimates varied from -.11 to .19. Sample differences between introductory psychology student mean PSNI total and subscale scores and Counseling Center client mean PSNI total and subscale scores proved significant. Recommendations for subsequent research and future application are offered.     

A measure for the assessment of eating disorders: reliability and validity studies of the Rating of Anorexia and Bulimia interview - revised version (RAB-R)

The Rating of Anorexia and Bulimia interview (RAB) is a Swedish semi-structured interview for clinical and research purposes for a wide range of eating disorder symptoms and related psychopathology. The objectives were to evaluate the reliability and validity of a revised RAB version (RAB-R). The RAB-R was assessed in terms of internal consistency, inter-rater and test-retest reliability, and criterion and convergent validity. Samples included a clinical sample of eating disorder patients (n = 71) and a sample of randomly drawn female controls (n = 31). The RAB-R showed satisfactory internal consistency, inter-rater and test-retest reliability, correlated well with related measures, and discriminated between patients and normal controls. We conclude that the RAB-R is a promising interview instrument and continued evaluation should focus on comparing subgroups of eating disorder patients with other clinical groups.     

The Tourette's Disorder Scale (TODS): development, reliability, and validity

To address the lack of a simple and standardized instrument to assess overall illness severity of Tourette's disorder (TD), the authors developed and tested a 15-item scale to measure a broad range of common symptoms including tics, inattention, hyperactivity, obsessions, compulsions, aggression, and emotional symptoms. Independent investigators used the 15-item Tourette's Disorder Scale (TODS) to assess 60 TD patients who were taking part in a double-blind placebo-controlled multicenter 8-week treatment study. Interrater reliability, internal consistency, convergent and discriminant validity, and sensitivity to change were examined. The TODS was associated with good interrater reliability, excellent internal consistency, and favorable levels of validity and sensitivity to change. Individual TODS items showed good convergent and discriminant validity against other measures. The TODS is a simple, efficient way for clinicians and parents to rate the severity of multiple symptoms commonly found in patients with Tourette's disorder.     

Development of a Scale to Assess Posttraumatic Stress Disorder

This study presents a newly developed self-report Posttraumatic Stress Scale (PTSS) based on the DSM-IV (American Psychiatric Association, 1994). The scale assesses the trauma experienced by people via the specific criteria of reexperiencing, numbing and avoidance, hyperarousal, and functioning. The instrument was validated on 52 Vietnam veteran subjects diagnosed with posttraumatic stress disorder (PTSD), 64 subjects who were attending professional counseling for trauma-related incidents, and 176 subjects who had never been diagnosed with PTSD or had professional counseling. The test survey comprised the PTSS, Beck's Anxiety Inventory, Beck's Depression Inventory, Impact of Events Scale, the 12-item General Health Questionnaire, Inventory of Depressive Symptomatology, and Symptoms Checklist–90R. The test-retest reliability of the scale was assessed over a four- to six-week period. The scale had a high test-retest reliability and showed high convergent and concurrent validity. Construct validity as assessed through the comparison between the three groups was high; however, factor analysis revealed only two factors instead of the three factors assumed in the DSM-IV. Overall, the scale may be used by clinicians or clients.     

Reliability and validity of scores on the Slosson Auditory Perception Skills Screener

Psychometric characteristics of the Slosson Auditory Perception Skills Screener were studied using three independent samples of boys and girls ages 5-10 years (N= 1,170). Internal consistency of scores ranged from .83 to .90 for the total scale, while 30-day test-retest reliability was .82 (n=58). A convergent validity coefficient between the Slosson Auditory Perception Skills Screener and Test of Auditory Perceptual Skills-Revised Total Score was .59 (n=67, p<.05). Thus, scores derived from administration of the Slosson Auditory Perception Skills Screener had adequate internal consistency and temporal stability, as well as good convergent validity.     

The validity of the PTSD checklist as a measure of symptomatic change in combat-related PTSD

Little research to date has examined the ability of self-report measures to assess changes in symptom severity and diagnostic status as a function of treatment. This study investigated the validity of the posttraumatic stress disorder (PTSD) checklist (PCL) as a measure of symptomatic change following programmatic treatment. A sample of 97 Vietnam veterans with combat-related PTSD was assessed using the clinician-administered PTSD scale (CAPS) and the PCL prior to, and 9 months following, participation in a PTSD treatment program. Using the CAPS as the "gold standard" measure of PTSD symptomatology, the PCL demonstrated high diagnostic accuracy pre- and posttreatment. However, significant variations in accuracy were evident in the ability of the PCL to determine the presence and severity of individual symptoms at each time point. In addition, as symptoms improved from pre- to posttreatment, and approached the threshold criteria, the PCL demonstrated reductions in diagnostic accuracy. As a measure of overall symptomatic change, the PCL underrated improvement in comparison to the CAPS. The results supported the use of an overall cut-off score of 50 on the PCL for a diagnosis, and an item score of 3 for symptom criterion, in this population.     

Image of aging scale

The development of the Image of Aging Scale is described. It ineludes positive and negative images of elders within nine domains. The scale showed good 1-wk. test-retest reliability, internal consistency, and convergent validity.     

The North Carolina Dissociation Index: A Measure of Dissociation Using Items From the MMPI-2

The development of a new measure of dissociation using items from the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) is described. In Experiment 1,525 college students were administer ed a measure of hypnotic susceptibility and completed several specialized measures of dissociation or dissociation-like experiences. The new measure, the North Carolina Dissociation Index (NCDI), demonstrated adequate internal consistency and good convergent validity. In Experiment 2, the NCDI demonstrated adequate internal consistency and test-retest reliability with a different sample of college students. Moreover, NCDI scores showed a relatively strong correlation with an interview-based measure of dissociative symptoms. In addition, a small sample of students with dissociative disorders had significantly higher NCDI scores than students with anxiety disorders and normal control subjects. In Experiment 3, 19 gang combat veterans were administered a semi-structured diagnostic interview and the MMPI-2, Subjects who were diagnosed with Posttraumatic Stress Disorder (PTSD) scored significantly higher on the NCDI than subjects who did not have PTSD. The NCDI is intended primarily as a tool in settings where the MMPI-2 is routinely administered.     

Assessing Fear of Storms and Severe Weather: Validation of the Storm Fear Questionnaire (SFQ)

To date, research on storm phobia has been limited by a lack of validated self-report measures for evaluating the severity of anxiety, phobic avoidance, and distress associated with storms and severe weather. The current research presents the development and validation of the Storm Fear Questionnaire (SFQ), a 15-item self-report questionnaire that assesses the cognitive, affective, and behavioral aspects thought to be associated with Storm Phobia in adults. Three studies were conducted to assess 1) the factor structure, internal consistency, and convergent and discriminant validity of the SFQ, 2) the test-retest reliability of the SFQ, 3) the extent that scores on the SFQ were associated with subjective anxiety ratings during a Behavioral Approach Test (BAT) involving exposure to a virtual thunderstorm, and the extent to which SFQ scores distinguished community participants with versus without a fear of storms. Exploratory factor analyses supported a one-factor model with good internal consistency (Cronbach’s α?=?.95), good convergent and discriminant validity with self-report measures of anxiety, worry, depression, and other specific phobias, and acceptable test-retest reliability. Moreover, there was a significant positive association between SFQ scores and anxiety ratings following the BAT involving exposure to a virtual thunderstorm and participants with a high fear of storms reported significantly higher SFQ scores than those with a low fear of storms. In sum, the SFQ has good psychometric properties and appears to be a valuable tool for assessing the severity of fear associated with storms and severe weather. Research evaluating the diagnostic and clinical utility of the SFQ is still needed.     

Psychometric properties of the Brief Symptoms Inventory-18 (Bsi-18) in a Spanish sample of outpatients with psychiatric disorders

This study analyzes the psychometric and structural properties of the BSI-18 in a sample of Spanish outpatients with psychiatric disorders (N = 200), with three basic objectives: (a) to study the structural validity of the instrument; (b) to analyse reliability (internal consistency and test-retest stability) and validity (convergent and discriminant) of the instrument, and (c) to evaluate sensitivity to change in a therapeutic context. Using confirmatory factor analysis, two models were tested: the three-dimensional theoretical model proposed by its authors, and the empirical four-factor model obtained by the same authors through exploratory factor analysis. Our results showed that the best structure was a four-dimensional model, with the General Distress index and Somatization, Depression, General Anxiety and Panic scores. These four scales showed good internal consistency, test-retest reliability, validity and sensitivity to therapeutic change. The BSI-18 has been shown to be a reliable and useful tool for psychiatric assessment of patients, with the added advantage provided by its simplicity and ease of application.     

The Greek Version of the Difficulties in Emotion Regulation Scale: Testing the Factor Structure, Reliability and Validity in an Adult Community Sample

We examined the factor structure, reliability, convergent and criterion validity of the Greek version of the Difficulties in Emotion Regulation Scale (DERS) using data from a community lifespan sample. Exploratory and confirmatory factor analyses revealed a clear six-factor structure consistent with the factor structure evidenced in English-speaking samples. The results also demonstrated adequate classical psychometric properties in terms of internal consistency and test-retest reliability. The scale branches demonstrated convergent and concurrent validity with personality, emotion intelligence abilities and coping strategies. The importance of using culturally validated dimensional measures of emotion regulation is discussed.     

Psychometric properties of the OCI-R in a college sample

Two studies examined the psychometric properties of the Obsessive-Compulsive Inventory-Revised (OCI-R; Psychol. Assessment 14 (2002) 485) in a nonclinical student sample. In Study 1, we investigated the factor structure and internal consistency of the OCI-R using a sample of 395 undergraduate students. At a second testing session 1 month later, 178 students completed the OCI-R. Test-retest reliability was examined using data from 94 students who completed the OCI-R in both sessions. Convergent validity was also assessed with the Maudsley Obsessive-Compulsive Inventory (MOCI). In Study 2, we further investigated the convergent and divergent validity of the OCI-R using a new sample of 221 students who completed a battery of measures of obsessive-compulsive symptoms, worry, and depression. There was a significant order effect for both the OCI-R and the MOCI: means of each measure were significantly lower when presented second. Despite the order effect, statistical analyses indicated that the OCI-R has adequate test-retest reliability for the full scale and subscale scores, solid factor structure, and high internal consistency. Convergent validity with other measures of obsessive-compulsive symptoms was moderate to excellent, and divergent validity was good. The results indicate that the OCI-R is a short, psychometrically sound self-report measure of obsessive-compulsive symptoms.     

Validation of the WHOQOL-BREF in a Sample of Male Treatment-Seeking Veterans

We examined the psychometric properties of a quality of life measure, the WHOQOL-BREF, in male treatment-seeking veterans. A sample of 131 veterans at an outpatient clinic completed a mail-in survey that included the WHOQOL-BREF as well as measures of posttraumatic stress, depression, anxiety symptoms, and functional health status. The WHOQOL-BREF showed evidence of good internal consistency and strong test-retest reliability. In addition, analysis of results demonstrated evidence of construct, convergent, and discriminant validity. The results suggest that the WHOQOL-BREF is a reliable and valid measure that can be used in the planning of psychological services provided to veterans with mental health problems.     

Validation of the Preschool and Early Childhood Functional Assessment Scale (PECFAS)

Efforts to determine the prevalence of serious emotional disturbance in preschool-aged children have been hampered by the lack of a validated measure. The Preschool and Early Childhood Functional Assessment Scale (PECFAS) is a multi-dimensional measure that assesses the psychosocial functioning of children aged 3–7 years. The concurrent validity and reliability of the PECFAS were assessed in a sample of 30 preschool-aged children in a large Head Start program in Ventura, California. PECFAS ratings based on in-depth interviews were significantly related to parental ratings that the children had mental health problems, psychiatric diagnoses, teacher ratings of the child's need for mental health evaluations, teacher ratings of behavior problems on a standardized screening inventory (DIAL-R), and actual referrals for mental health evaluations. Interrater reliability for the total PECFAS score was high (r = .90) as was internal consistency of the five subscales (alpha = .86). Using the PECFAS scores as a standard, the weighted prevalence of serious emotional disturbance in this West Coast Head Start program was 17%, at the lower end of the current estimated rate of SED for older children in low income samples (18–26%).     

Psychometric Properties and Factor Structure of the French Version of the Behavioral Activation for Depression Scale (BADS) in Non-Clinical Adults

Behavioral activation (BA) is a well-established empirical treatment for depression that aims to improve depressive mood by increasing activation and reducing avoidance. Therefore, it is essential to evaluate activation and avoidance when a BA treatment is applied. The Behavioral Activation for Depression Scale (BADS) was developed to measure the changes in activation and avoidance over the course of BA treatment of depression. This study aims to validate the French version of this scale. In a first study, 131 bilingual adults were recruited to explored internal consistency, test-retest reliability and construct validity of the final French version. In a second study, 409 non-clinical adults completed an online survey assessing concurrent measures. Results of the first study suggested good internal consistency, test-retest reliability and construct validity. The second study revealed a confirmatory factor analysis supporting the original four-factor structure, with Activation, Avoidance/Rumination, Work/School Impairment, and Social Impairment subscales. Results also revealed that a 5-factor model distinguishing Behavioral Avoidance and Rumination had a better fit than the original four-factor structure. All subscales showed adequate internal consistency and good construct validity with evidence of convergent validity with depressive symptoms, brooding, psychological flexibility, negative automatic thought, behavioral inhibition and activation system. Furthermore, the French BADS total scale and subscales showed a good ability to predict depressive symptoms. The French version of the BADS appears to be a reliable tool for clinician and researchers to assess mechanisms of change in BA interventions.
