A dimensional analysis of the Yale-Brown Obsessive Compulsive Scale.

A principal axis factor analysis with a Promax rotation was performed on the Yale-Brown Obsessive Compulsive Scale. Although the scale has separate obsession and compulsion indices, only one factor was extracted. The psychometric implications of this finding are discussed.     

What Drives OCD Symptom Change During CBT Treatment? Temporal Relationships Among Obsessions and Compulsions

Cognitive behavior therapy (CBT) is an effective treatment for obsessive-compulsive disorder (OCD). However, less is known about how obsessions and compulsions change during treatment, either in tandem, sequentially, or independently. The current study used latent difference score analysis to show path-analytic dynamic modeling of OCD symptom change during CBT. Four competing models of the temporal relationship between obsessions and compulsions were examined: no coupling (obsessions and compulsions are not dynamically related), goal directed (obsessions lead to subsequent changes in compulsions), habit driven (compulsions lead to subsequent changes in obsessions), and reciprocal. Treatment seeking participants (N = 84) with a principal diagnosis of OCD completed 12 weeks of CBT group therapy and completed measures assessing obsession and compulsion severity at pretreatment, Sessions 4 and 8, and end of treatment. Bivariate results supported the goal directed traditional CBT model, where obsession scores are temporally associated with subsequent changes in compulsion scores. These results have implications for theoretical and treatment modelling of obsessions and compulsions in OCD treatment.     

Does Motivation Impact OCD Symptom Severity? An Exploration of Longitudinal Effects

Understanding the role of patient motivation in OCD treatment is of clinical importance given the requisite autonomous role of patients in Exposure and Response Prevention. The present study investigated state- and trait-like relations between three variables: two previously established motivational constructs, readiness to change (RTC) and committed action (CA), derived from the University of Rhode Island Change Assessment, and OCD symptom severity as measured by the self-report Yale-Brown Obsessive Compulsive Scale (Y-BOCS-SR). Utilizing a random-intercept cross-lagged panel model (RI-CLPM) design, we assessed autoregressive, within-time correlations, and cross-lagged effects of RTC, CA, and Y-BOCS-SR scores at admission, month 1 of treatment, and discharge from an intensive/residential treatment program for OCD. Results revealed significant autoregressive (i.e., state-like) effects for CA and Y-BOCS-SR, negative within-time correlations between state CA and Y-BOCS-SR across all time points, a positive within-time correlation between state CA and RTC at admission, and a cross-lagged effect between state Y-BOCS-SR at month 1 of treatment and state RTC at discharge. Results also demonstrated that the stability of the RTC variable was attributable to trait-like factors in the present sample. This study is novel in its use of RI-CLPM in an OCD sample and represents an important addition to the literature on the longitudinal impacts of dynamic constructs of motivation. Our findings may provide future researchers with strategies to supplement ERP with CA-driven motivational interviewing.     

The structure of childhood obsessions and compulsions: dimensions in an outpatient sample

While obsessive-compulsive disorder (OCD) is defined as a unitary condition, prior research has identified meaningful and distinct symptom dimensions in adult samples. In contrast, there have been no investigations of symptom dimensions in samples of children diagnosed with OCD. The present study sought to address this gap. Children diagnosed with OCD (n = 137) were administered the Children's Yale-Brown Obsessive-Compulsive Scale symptom checklist and severity index. Symptoms were analyzed using principal components analysis. As with adult samples, four factors were identified from the checklist. However, these four factors (compulsions, sexual/aggressive obsessions, superstitions, and hoarding/ordering/somatic concerns) were different in content from adult studies. Further, several symptoms significantly contributed to more than one dimension. Each dimension was significantly correlated with scores from the severity index, with the exception of the obsession score with the hoarding/ordering/somatic concerns factor. Results suggest that there are distinct dimensions of symptoms in childhood OCD, but that these dimensions do not correspond to those identified in adults. Instead, it appears that some factors share variance, and the dimensions themselves are separated based upon developmental trajectories. The dimensions examined may be useful in future treatment studies using pharmacological and/or behavioral interventions.     

Post-stroke depression: Main phenomenological clusters and their relationships with clinical measures

Objectives: To investigate the principal psychopathological dimensions of post-stroke depression (PSD) through the assessment of the factorial structure of the Post-Stroke Depression Rating Scale (PSDRS). Methods: We enrolled ninety-eight subjects with PSD, who underwent the PSDRS, MMSE and Barthel Index. Information about demographic, clinical, and neuroanatomical factors was collected. Results: The factor analysis extracted three factors accounting for 63.4% of the total variance, and identified as: 1) "Depressive and Anxious Symptoms" (DAS); 2) "Lack of Emotional Control" (LEC); 3) "Reduced Motivation" (RM). On multivariate statistics, DAS severity was predicted by previous history of mood disorders and Barthel Index; LEC severity was predicted by Barthel Index; RM severity was predicted by age. Conclusions: The PSDRS displayed a reliable factor structure that agreed with previous interpretation of PSD. In particular, core depressive symptoms seem to be related to premorbid personality and functional status, whereas apathy/anhedonia may be connected to brain aging.     

An Examination of the Psychometric Properties and Factor Structure of the Feelings of Stigmatization Questionnaire

As the experience of stigma and its psychological dimensions require careful measurement, the purpose of this study was to examine the psychometric properties and factor structure of the Feelings of Stigmatization Questionnaire (FSQ). A total of 170 participants with psoriasis and 124 with atopic dermatitis (AD) completed the FSQ. AD participants self-rated AD severity, while psoriasis severity was determined by a clinician. Confirmatory (CFA) and exploratory factor analytic (EFA) techniques were used to examine the factor structure of the FSQ. The FSQ total score was not related to age, age at onset, illness duration or psoriasis severity but it was negatively associated with AD severity (r = −.25, p < .01). The original six-factor structure of the FSQ was not replicated in our sample. Using EFA, a fixed three-factor solution proved the most stable, with the dimensions of feeling flawed, anticipation of rejection and secrecy, and positive attitudes towards skin disease being identified.     

A standardized behavioral group treatment program for obsessive-compulsive disorder: preliminary outcomes

This paper provides outcome data about the efficacy of a behavioral group therapy program for obsessive-compulsive disorder (OCD). Thirty-six patients completed a 7-week outpatient treatment program which provides: (1) education about OCD and its treatment, (2) instruction in a cognitive and behavioral approach to the self-treatment of OCD and (3) guided behavioral treatment. Significant improvement in obsession, compulsion, and depression scores were observed at completion of the group and at 3 month follow-up. Significant improvement in obsessions and compulsions was observed for both patients taking anti-obsessional medications and those who did not.     

A psychometric evaluation of the Icelandic version of the WHO‐5

The psychometric properties of the Icelandic version of the World Health Organization five wellbeing index (WHO‐5) were evaluated using two samples, a randomly selected sample (N = 3,896) from the Icelandic National Registry and a convenience sample of primary care patients (N = 126). The factor structure of the scale was tested with confirmatory factor analysis (CFA). The correlation between the WHO‐5 and other measures of depression and anxiety were calculated to assess the scale's convergent and divergent validity. The discriminant validity of the WHO‐5 was explored with a receiver operating analysis compared to the Mini International Neuropsychiatric Interview. The CFA indicated that the factor structure of the WHO‐5 was one‐dimensional and factorial invariant between groups. The internal reliability of the WHO‐5 was adequate and the convergent, divergent and discriminant validity of the WHO‐5 was supported. It is concluded that the psychometric properties of the Icelandic version of the WHO‐5 are satisfactory.     

The Comparison of Death Anxiety,Obsession, and Depression Between Muslim Population with Positive and Negative Religious Coping

Death anxiety, obsession, and depression constitute three dimensions of death distress which can be influenced by religious coping in religious individuals. The aim of this study was to compare death anxiety, depression, and obsession between Muslims with positive and negative religious coping. In a cross-sectional study, a sample of 339 participants were selected via stratified random sampling method. The participants were screened using the Brief Religious Coping Scale, in which 60 individuals were identified to have positive religious coping and 62 individuals were recognized as individuals with negative religious coping. They responded to Death Anxiety Scale, Death Obsession Scale, and Death Depression Scale. The data were analyzed using factor analysis and multiple analysis of variance. The results of principal component analysis showed that death anxiety, death obsession, and death depression were separate factors of death distress. The results also revealed that individuals with negative religious coping gained higher scores than those with positive religious coping in all the three variables of death anxiety, obsession, and depression. Consistent with the previous studies and Terror Management Theory, this finding lays emphasis on the role of positive religious coping in reducing death distress and the possible consequent psychopathology.

     

A culture-sensitive approach in the development of the Career Adapt-Abilities Scale in Iceland: Theoretical and operational considerations

The aim of this study was to develop a culturally sensitive version of the Career Adapt-Ability Scale (CAAS) in Iceland. First the translated international version of the 55-item CAAI designed to measure the four dimensions of career adaptability (concern, curiosity, control, and confidence) plus additional dimension called co-operation was administered to a sample of 491 secondary school students. Confirmatory factor analysis indicated that both the four- and five-dimensional model show an adequate fit in the sample. An emic evaluation of the international model indicated that new facets tentatively called fatalism and contribution might be relevant in Iceland. New contextualized Icelandic items were written resulting in a combined 89-item measure of international and indigenous items administered to a sample of 1249 university students. Exploratory factor analysis supported contribution as a separate dimension and was used to create Icelandic scales measuring six dimensions: co-operation, contribution, and the four original dimensions. Confirmatory factor analysis supported the fit of three alternative 4–6-dimensional international and Icelandic models and measures of career adaptability in Iceland. An emic approach is needed to understand the cultural specificity and universal aspects of career adaptability and to develop culturally sensitive measures for use in career counseling. Further research on co-operation and contribution as relational constructs is suggested.     

The Prevalence of Depressive Symptoms in Pre-adolescent School Children in Iceland

Abstract

The Icelandic translation of the Children Depression Inventory (CDI) was administered to 436 children attending fifth through ninth grade of primary school (228 girls and 208 boys). The cohort was composed of three equally big groups, from the fifth to sixth grade, seventh grade and eight to ninth grade. The CDI total scores were somewhat lower than in most Anglo-Saxon studies. A cut-off score of 15 identified the upper 10% of the children as depressed. An analysis of variance yielded a significant difference due to grade, but no sex difference, and no interaction between grade and sex. The reliability of the inventory was satisfactory. The factor structure found by Kovacs (1992) was not replicated. It is proposed that total scores should be used rather than scores on specific factors for the Icelandic translation.     

Handbook of Religious Conversion (Book)

The relation among traditional Christian beliefs, spiritualism, and the paranor- mal was the subject of a factor-analytical study to compare religious-paranor- ma1 belief structures of samples in Iceland and the United States (Louisiana, Virginia, and Illinois). Tobacyk's 25-item Paranormal Belief Scale (Tohacyk and Milford, 1983) was administered to 349 Icelandic students. The same seven factors emerged in Iceland as in Louisiana but the strength of the various factors differed considerably among the two samples. The Traditional Religious Belief factor, which explained most of the variance in the Louisiana samples, was fifth in Iceland, where the Spiritualism factor emerged as the strongest but was fifth in the United States. The Psi factor showed comparable strength in both samples. The Icelandic sample revealed itself as less believing on all subscales (factors) except on the Spiritualism subscale where it was comparable to the U.S. sample.     

Measuring Obsessions Without Worry: Convergent and Discriminant Validity of the Revised Padua Inventory in an Icelandic Student Population

The revised Padua Inventory (Padua Inventory-Washington State University Revision or PI-WSUR) was investigated in an Icelandic student population ( n = 431). The inventory was explicitly constructed to minimize the overlap between the measurement of obsessionality and worry. Its relationships with the Maudsley-Obsessive-Compulsive Inventory (MOCI) and the Penn State Worry Questionnaire (PSWQ) were investigated. The factor structure of the PI-WSUR was studied as well as the relations of PI-WSUR subscales with corresponding scales on the MOCI (checking, contamination). It was further investigated whether a factor analysis of the PI-WSUR together with PSWQ would indicate that the PI-WSUR and its different components were relatively uncontaminated by variance shared with worry. The results generally supported the psychometric properties of the Icelandic version of the PI-WSUR as well as its relative independence of PSWQ specifically.     

A dyadic exploration of attachment and caregiving in long‐term couples

This cross‐sectional study explored associations between attachment style and caregiving patterns in 125 couples with children in the United Kingdom. The Actor–Partner Interdependence Model was used to model for both actor (own) and partner attachment effects on caregiving. Attachment was measured along the dimensions of avoidance and anxiety, and caregiving was measured along the dimensions of proximity, sensitivity, cooperation, and compulsion. Results indicated that different combinations of individual and partner attachment scores predicted different dimensions of caregiving. Own attachment scores best predicted caregiving proximity, cooperation, and compulsion, whereas own and partner attachment predicted caregiving sensitivity. The implications of the findings, limitations, and suggestions for future research are discussed.     

Beliefs About God and Mental Health Among American Adults

This study examines the association between beliefs about God and psychiatric symptoms in the context of Evolutionary Threat Assessment System Theory, using data from the 2010 Baylor Religion Survey of US Adults (N = 1,426). Three beliefs about God were tested separately in ordinary least squares regression models to predict five classes of psychiatric symptoms: general anxiety, social anxiety, paranoia, obsession, and compulsion. Belief in a punitive God was positively associated with four psychiatric symptoms, while belief in a benevolent God was negatively associated with four psychiatric symptoms, controlling for demographic characteristics, religiousness, and strength of belief in God. Belief in a deistic God and one’s overall belief in God were not significantly related to any psychiatric symptoms.     

Psychometric properties of the Multidimensional Anxiety Scale for Children (MASC) among Icelandic schoolchildren

A psychometric assessment of the Icelandic version of the Multidimensional Anxiety Scale for Children (MASC) was undertaken among Icelandic schoolchildren, between 10 and 15 years of age. In a first study 625 children between 10 and 15 years of age filled in the MASC. A confirmatory factor analysis indicated that the four-factor structure of the instrument was justified. Further, means and standard deviations of the total scale and the subscales were similar to the original normative data reported by March (1997). In a second study the MASC, the Children Depression Inventory (CDI) and the Revised Children's Manifest Anxiety Scale (RCMAS) were administered to a sample of 249 schoolchildren between 10 and 15 years of age. The results supported the convergent and divergent validity of the MASC. Together the two studies show satisfactory psychometric properties of the Icelandic version of the MASC in a normal population.     

Developing of an English Version of the Aggressive Driving Behavior Test (AVIS). Improving the Construct Validity of Aggressive Driving

The research investigated the psychometric properties and the discriminant validity of the English version of the Questionnaire for the Assessment of Aggressive Driving Behavior (AVIS). Study 1 assessed the psychometric properties of the instrument. Internal consistency ranged from 0.77 to 0.92. Exploratory factor analysis did not support the original five factor structure, Instrumental Aggression and Acting Out being unified in a single factor. Following the confirmatory factor analysis a version with 26 items and 3 factors was obtained. Inter-scale correlations showed that the dimensions of the AVIS are inter-correlated. Study 2 verified the discriminant validity of the English version of the AVIS by testing the relationships between the AVIS dimensions and the DAX (Driving Anger Expression Inventory) dimensions. The results showed good discriminant validity, the dimensions of the two instruments being uncorrelated. In conclusion, the findings contribute to the development of the driving aggression construct by adding new dimensions to it.     

Dimensionality and psychometric invariance of the Youth Self-Report Form of the Child Behavior Checklist in cross-national settings

The Youth Self-Report Form's (YSR's) factor model was derived from traditional exploratory factor analytical procedures. Assuming appropriate model specification, psychometrically invariant items, and that its items provide useful psychometric information across nations omitted from its normative samples, the YSR is widely used in cross-national studies of nonreferred children. Item response theory analytical procedures reveal (a) 2 dimensions partly overlapping with the YSR's Internalizing and Externalizing second-order factors; (b) variance (i.e., differential item functioning) in how well a few items discriminate for nonreferred children across two nations; and (c) variance in estimating severity levels in children with identical psychopathological severity cross-nationally. Addressing psychometric variance, limiting redundancy, and matching children's psychopathological severity levels with items measuring this severity might promote more accurate and economical assessment.     

Parents' estimations of their own intelligence and that of their children: a comparison between English and Icelandic parents

In this study, 158 parents (79 fathers and 79 mothers) with a mean age of 38.3 yrs (SD = 8.2), estimated their own, and their children's, overall intelligence as well as their children's score on the 12 intelligence scales from the Wechsler's Intelligence Scale for Children (WISC-III). The sample included English (n = 122) and Icelandic parents (n = 36), and a comparison between them showed few differences except that Icelandic parents' estimates were lower than English parents' estimates. The results showed fathers estimated their own overall intelligence higher than mothers estimated theirs and sons were estimated higher than daughters on overall intelligence. Two factors (verbal, performance) of intelligence were identified through factor analysis of the ratings of the 12 WISC subscale score estimates. A hierarchical regression showed that these two factors explained most of the variance in the estimation of the child's overall intelligence; however, gender of child and parents' self-estimated own overall intelligence added incremental variance.     

Anxiety sensitivity cognitive concerns drive the relation between anxiety sensitivity and symptoms of depression

Depression is typically treated as a homogeneous construct despite evidence for distinct cognitive, affective, and somatic symptom dimensions. Anxiety sensitivity (AS; the fear of consequences of anxiety symptoms) is a cognitive risk factor implicated in the development of depressive symptoms. However, it is unclear how lower order AS dimensions (i.e. physical, cognitive, and social concerns) relate to depressive symptom factors. Confirmatory factor analysis, followed by structural equation modeling, were conducted to examine the factor structure of depression and to then examine the relations between these factors and the lower order factors of AS. This study was conducted in a sample of 374 adults (M age = 35.5, 54.3% female) with elevated levels of psychopathology (89.2% meeting criteria for at least one DSM-5 diagnosis, 25.6% primary depressive disorder). In this study a two-factor model of depression, composed of Cognitive and Affective/Somatic factors, was superior to one- and three-factor solutions. AS cognitive concerns were related to both cognitive and affective/somatic symptoms of depression. Neither of the other AS dimensions was related to depression symptom dimensions. These findings provide a better understanding of the relations between AS and depression symptoms.
