Dimensionality of the Beck Anxiety Inventory in a Polytrauma Sample of OEF/OIF/OND Veterans: Findings From Exploratory and Confirmatory Factor Analysis

The Beck Anxiety Inventory (BAI) is commonly used as a screening instrument for symptoms of anxiety in clinical settings. The factor structure has been researched in a variety of different clinical settings with results ranging from a 2- to 5-factor structure. The purpose of this study was to explore the factor structure of this instrument in a polytrauma veteran sample. A sample of 304 veterans was used for this study. All subjects were administered the BAI screening measure as part of an evaluation in an outpatient polytrauma clinic. Exploratory factor analysis was conducted for half of the sample, followed by confirmatory factor analysis for the remaining sample to determine the best model. Factor analyses revealed that a 5-factor model provided a best fit. It is interesting to note that previously identified models of the BAI with other types of samples did not provide the best fit for this polytrauma sample. The BAI may provide additional information for clinicians when examining the 5-factor model with veterans in polytrauma settings. The factor structure of the BAI includes 1 factor (i.e., personal safety) that may be unique for veterans who have served in combat zones.     

The Factor Structure of MASC Youth Report in Norwegian School Children

Identifying children with symptoms of anxiety before they develop clinical disorders is important. The objective of our study was to examine the latent factor structure of the MASC (youth report version) in a large self-selected sample of school children in 4th to 6th grade, and examine if the measure had a comparable factor structure for gender and age. Gender and age differences in anxiety symptoms were also examined. Children (N?=?1686, 53.8% female) were recruited from schools during pretest of an ongoing randomized, controlled, indicative intervention. Latent variable modelling was used to determine the underlying concepts of the MASC. We found good model fit for the four-factor model, however some items on the Harm/Avoidance scale had low factor loadings. Invariance analysis indicated that the MASC had similar factor structure (comparable meaning) for boys and girls and for younger and older children in this sample. Girls scored significantly higher than boys on all subscales and on the Total Anxiety scale. Age differences were only found on the Separation Anxiety scale. Overall, the original four-factor structure of the MASC was confirmed within a large sample of school children and was invariant across gender and age. However, the Harm/avoidance scale warrants some attention. The MASC is a potentially useful measure to be used for screening purposes in a school setting.     

Temperament,Repetitive Negative Thinking,and Depressive Symptoms in Early Adolescence: a Prospective Study

Repetitive negative thinking (RNT) is a transdiagnostic vulnerability factor, involved in the maintenance of a variety of emotional problems. Recently, the Perseverative Thinking Questionnaire – Child version (PTQ-C) was developed as a content-independent measure of RNT in children and adolescents. The current study investigated the reliability and predictive validity of the PTQ-C and examined temperament as a developmental predictor of RNT. For this end, 701 early adolescents completed measures of RNT, depressive symptoms, stressors, and temperament, both at baseline and after three months. First, the factor structure of the PTQ-C was investigated by comparing a one-factor model and a three-factor higher-order model using confirmatory factor analyses. Both models showed good fit to the data, but the more parsimonious one-factor model was retained. Internal consistency, as measured by cronbach’s alpha and (hierarchical) omega, was found to be excellent for the total scale. Second, associations with depressive symptom levels were examined. RNT predicted both concurrent and prospective symptom levels, even when taking into account baseline depressive symptoms. RNT was further shown to act as a moderator strengthening the link between stress and levels of depressive symptoms, both concurrently and prospectively. Finally, associations with temperament were explored by investigating the mediating role of RNT in the association between temperament dimensions and depressive symptoms. One indirect effect was found, with low effortful control predicting increases in depressive symptoms through heightened levels of RNT. The current study supports the PTQ-C as a useful and psychometrically sound measure of dysfunctional RNT that may facilitate research on emotional problems in child and adolescent samples.     

Factor Structure,Validity, and Reliability of the Japanese Version of the Balanced Index of Psychological Mindedness (BIPM)

This study examined the measurement properties of the Balanced Index of Psychological Mindedness (BIPM) among the Japanese population. Exploratory factor analysis was conducted to examine the factor structure of the BIPM (Study 1) among 464 university students, and confirmatory factor analysis examined the validity and reliability of the BIPM (Study 2) among 321 university students. Additionally, the mitigation effect of psychological mindedness (PM) for depressive symptoms was examined. The results showed a two-factor structure (Interest and Insight) similar to the original BIPM. The BIPM was negatively correlated with the alexithymia score and positively correlated with the Psychological Mindedness Scale and Openness. It was also significantly correlated with future depressive symptoms. The BIPM is useful for measuring PM in the Japanese population. Additionally, this study suggests clinical applications of PM in psychotherapy and the treatment effect mechanism of cognitive behavioral therapy.

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.     

Safety behaviors were associated with greater anxious symptoms during the first year of the COVID-19 pandemic

Research shows that people who use safety behaviors are at greater risk factor for anxiety than people who do not use safety behaviors. However, the perception of some safety behaviors changed during the COVID-19 pandemic; behaviors that were once considered unnecessary or excessive were now commonplace (e.g., monitoring bodily symptoms, avoiding crowds). The purpose of this study was to determine the degree to which the pandemic changed the status of health-related safety behaviors as a risk factor for symptoms of anxiety. To this end, we tested the effect of safety behavior use on anxious symptoms during the first year of the pandemic using a longitudinal design with 8 time points and participants (n = 233) from over 20 countries. Despite possible changes in their perception, those engaging in high levels of safety behaviors reported the greatest levels of anxious symptoms throughout the pandemic year. However, the outcomes for safety behavior users were not all negative. Safety behavior use at baseline was the only predictor of participants' willingness to receive the COVID-19 vaccine (measured one year later).     

Factor analytic investigation of the Illness Attitudes Scale in a chronic pain safmple

The Illness Attitudes Scale (IAS) is a self-report instrument comprising nine subscales designed to assess fears, beliefs and attitudes associated with hypochondriasis and abnormal illness behaviour [Kellner (1986). Somatization and hypochondriasis. New York: Praeger.]. The purpose of the present study was to explore the factor structure of the IAS in a chronic pain sample as a preliminary step toward determining the use of this measure in this sample. Hypochondriacal tendencies have been postulated to play a role in maintaining and exacerbating responses to chronic pain and, therefore, appropriate measurement in this sample is important. In the present study, consecutive chronic pain patients presenting to a pain treatment program (N=198) were administered the IAS. Principal component analysis with oblique (Oblimin) rotation identified that five factors best explain the measure in this population. These factors were (1) fear of illness, (2) effects of symptoms, (3) health habits, (4) disease phobia and conviction and (5) fear of death. The factor structure overlapped to some degree with the scoring of the IAS proposed by Kellner (1986), as well as with the factor structure identified in a non-clinical sample [Ferguson, E. & Daniel, E. (1995). The Illness Attitudes Scale (IAS): a psychometric evaluation on a non-clinical population. Personality and Individual Differences, 18, 463–469.]. There were enough discrepancies, however, to suggest an alternative method for scoring the IAS with chronic pain patients. Implications for the use of the measure with chronic pain patients, as well as future research directions for exploring the utility of this measure with chronic pain patients, are discussed.     

The role of coping styles as predictors of depressive symptoms among adolescents: a prospective study

The present study prospectively explored the main and interactive effect of approach and avoidant like coping styles, as well as school-related stress on depressive symptoms in a sample of 327 (167 females, 160 males) students in two Norwegian secondary schools. The results showed that seeking parental support as a coping style served as a negative predictor of later depression, and results give some support for aggressive coping styles being a risk factor for depressive symptoms. A significant interaction between aggressive coping style and stress in relation to depressive symptoms was found. We were also able to show that school-related stress at T(1) predicted depressive symptoms at T(2).     

Behavioural treatment of trichotillomania: two-year follow-up results

Post-treatment evaluation studies of behaviour therapy (BT) for trichotillomania (TTM) have shown that BT is successful in reducing symptoms in this impulse-control disorder. The present study was aimed at investigating gain maintenance at long-term follow-up. TTM-related symptoms and other symptom characteristics were evaluated in 28 patients suffering from TTM before and after brief BT and at a 3-month and 2-year follow-up. The manual-based BT consisted of self-control procedures offered in six sessions. Pre-post effect sizes for TTM symptoms at post-treatment evaluation and at the two follow-ups were 2.91, 1.47, and .87. Compared to the post-treatment effects, the 3-month and 2-year follow-up effect sizes had decreased by 49% and 70%, respectively. Better 2-year follow-up results were associated with lower pre-treatment levels of depressive symptoms and with complete abstinence from hair pulling immediately after treatment.     

An expanded childhood anxiety sensitivity index: its factor structure, reliability, and validity in a non-clinical adolescent sample

Anxiety sensitivity refers to the fear of anxiety-related bodily sensations that are interpreted as having potentially harmful somatic, psychological, or social consequences. The current study examined the factor analytic structure of anxiety sensitivity in a large sample of normal adolescents (N=518) using the revised childhood anxiety sensitivity index (CASI-R). Confirmatory factor analysis indicated that anxiety sensitivity as measured by the CASI-R can best be conceptualised as a hierarchical construct with four lower-order factors loading on a single higher-order factor. The lower-order factors were 'fear of cardiovascular symptoms', 'fear of publicly observable anxiety reactions', 'fear of cognitive dyscontrol', and 'fear of respiratory symptoms'. An additional aim of the present study was to investigate the psychometric properties of the CASI-R. Results showed the CASI-R to be a reliable scale in terms of internal consistency. Furthermore, CASI-R scores were substantially related to levels of anxiety sensitivity as measured by the original index, trait anxiety, symptoms of anxiety disorders, in particular 'panic disorder and agoraphobia', and depression. Finally, some evidence was found for the validity of the CASI-R factor scores. That is, all factors convincingly loaded on symptoms of 'panic disorder and agoraphobia', whereas the factor 'fear of publicly observable anxiety reactions' was also strongly associated with symptoms of 'social phobia'.     

Assessment of symptoms of DSM-IV anxiety and depression in children: a revised child anxiety and depression scale

The practical significance of assessing disorders of emotion in children is well documented, yet few scales exist that possess conceptual if not empirical relevance to dimensions of DSM anxiety or depressive disorders. The current study evaluated an adaptation of a recently developed anxiety measure (Spence Children's Anxiety Scale; [Spence, S. H. (1997). Structure of anxiety symptoms among children: a confirmatory factor-analytic study. Journal of Abnormal Psychology, 106, 280-297; Spence, S. H. (1998). A measure of anxiety symptoms among children. Behaviour Research and Therapy, 36, 545-566]), revised to correspond to dimensions of several DSM-IV anxiety disorders as well as major depression. This investigation involved initial evaluation of the factorial validity of the revised measure in a school sample of 1641 children and adolescents and reliability and validity in an independent sample of 246 children and adolescents. Results yielded an item set and factor definitions that demonstrated structure consistent with DSM-IV anxiety disorders and depression. The revised factor structure and definitions were further supported by the reliability and validity analyses. Some implications for assessment of childhood anxiety and depressive disorders are discussed.     

Assessment of Discipline Styles Among Parents of Preschool Through School-Age Children

The Parenting Scale (D.S. Arnold, S.G. O'Leary, L.S. Wolff, & M.M. Acker, 1993) is a self-report measure of parenting practices that has demonstrated sound psychometric properties when used with the parents of young children. However, less is known about the use of this measure with parents of older children. This study was conducted to examine the psychometric properties and factor structure of the Parenting Scale in a normative sample of parents with children 2–12 years old. Findings reveal that the psychometric properties remain strong among the parents of elementary school children, with minimal differences in scores as a function of children's age. However, the data suggest that the factor structure may differ from that proposed by the authors. Although statistically significant correlations with ADHD symptoms were revealed, the magnitude of these correlations was relatively small. Suggestions for future research and clinical use of this scale are discussed.     

Four studies on how past and current suicidality relate even when "everything but the kitchen sink" is covaried

T. E. Joiner's (2004, in press) theory of suicidal behavior suggests that past suicidal behavior plays an important role in future suicidality. However, the mechanism by which this risk is transferred and the causal implications have not been well studied. The current study provides evaluation of the nature and limits of this relationship across 4 populations, with varying degrees of suicidal behavior. Across settings, age groups, and impairment levels, the association between past suicidal behavior and current suicidal symptoms held, even when controlling for strong covariates like hopelessness and symptoms of various Axis I and II syndromes. Results provide additional support for the importance of past suicidality as a substantive risk factor for later suicidal behavior.     

Factor Structure of the PTSD Checklist in a Sample of OEF/OIF Veterans Presenting to Primary Care: Specific and Nonspecific Aspects of Dysphoria

Although DSM-IV-TR diagnostic criteria for posttraumatic stress disorder (PTSD) include three primary symptom clusters, recent evidence from confirmatory factor analyses suggest that the latent structure of PTSD is better represented by four factors, which will likely be reflected in the upcoming DSM-5. Given this likely transition from three to four clusters, the present study sought to examine specific and non-specific aspects of dysphoria in the factor structure of PTSD symptoms in a sample of OEF/OIF combat veterans presenting to a Veterans Affairs primary care clinic. PTSD symptoms were assessed using the PCL-M (Weathers et al. 1993). Results from confirmatory factor analyses suggested that a dysphoria factor involving a number of non-specific distress symptoms may be an important part of the PTSD symptom profile. After controlling for variance due to general psychological distress, we further found that factor loadings on the dysphoria factor were attenuated but continued to significantly load onto the factor, suggesting that dysphoria may be a specific part of the PTSD symptom constellation.     

Stability in schizophrenia symptoms over time: findings from the Mount Sinai Pilgrim Psychiatric Center Longitudinal Study

This study examined the stability of symptoms of schizophrenia over time, focusing on the stability of symptom structure. Symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS). The sample consisted of 215 chronic patients followed up for as long as 4 years. Exploratory factor analysis identified 6 factors. Several statistical techniques were used to examine the stability of these symptoms, including longitudinal confirmatory factor analysis. Low-to-moderate rank-order stability and high absolute stability of the factors were found, with the structure of the PANSS-assessed symptoms consistent over time. The results demonstrate that despite changes in the severity of symptoms in individual patients with schizophrenia, the factor structure and interrelatedness of symptoms have considerable stability over time.     

Post-Traumatic Reactions in Adolescents: How Well Do the DSM-IV PTSD Criteria Fit the Real Life Experience of Trauma Exposed Youth?

This study examined the structure and symptom specific patterns of post traumatic distress in a sample of 1,581 adolescents who reported exposure to at least one traumatic event. Symptom reporting patterns are consistent with past literature in that females reported more symptoms than males and older youth reported more symptoms than did their younger peers. Young people reporting exposure to exclusively violent type traumas were also found to be more likely to endorse symptoms than peers exposed exclusively to non violent type traumas. Confirmatory factor analysis provided stronger support for a four-factor model of PTSD than either the DSM-IV model or an alternate model. Further examination of the four factor model revealed gender differences in factor loadings with small to moderate effect sizes for recurrent, distressing memories, flashbacks, restricted affect, difficulty remember details, detachment, limited future orientation, hypervigilance and startle symptoms. Differences in factor loadings with the four factor model were also noted between younger and older adolescents, with medium to large effect sizes on the arousal items. In contract, comparison of the factor loadings revealed only small differences between youth exposed exclusively to violent traumatic stressors and those exposed exclusively to non violent traumatic stressors, suggesting relative similarity between these two groups.     

The effect of smoking on brainstem auditory evoked potentials in positive- and negative-symptom schizophrenia

Studying brainstem auditory evoked potentials (BAEPs) and comparing the specific waves in smokers vs nonsmokers in both positive- and negative-symptom schizophrenia may elucidate the role of smoking in information processing. BAEPs were recorded in 40 patients with schizophrenia; 20 had predominantly positive symptoms (10 smokers and 10 nonsmokers) and 20 had predominantly negative symptoms (10 smokers and 10 nonsmokers). The severity of positive and negative symptoms was assessed by scale of assessment of positive symptoms and scale of assessment of negative symptoms (SANS). The BAEP results were compared with 15 healthy control individuals matched with the patients by age, sex, and cultural background. The smokers with negative symptoms showed a significant increase in the alogia, summary, and composite scores of SANS as compared to the nonsmokers. Although, most of the BAEP abnormalities were among patients with positive symptoms. The effect of smoking on the BAEPs was only in patients with negative symptoms. We also studied the interaction between smoking factor (smokers vs nonsmokers) and group type (group with mostly positive symptoms vs group with mostly negative symptoms) on the BAEPs and found a significant difference only for the first-wave latency mainly on the right side (P=0.012). The absence of a significant effect of smoking on most of the parameters of the BAEPs on interaction with the group factor suggests that the effect of smoking on the BAEPs is more apparent when negative symptoms prevail. However, studies are warranted to substantiate this finding.     

The Effects of Experimentally Induced Rumination Versus Distraction on Analogue Posttraumatic Stress Symptoms

Rumination has been suggested to be an important factor maintaining posttraumatic stress disorder (PTSD). Using an analogue design, this study aimed to experimentally test the hypothesis that trauma-related rumination maintains PTSD symptoms. Fifty-one participants were first asked to give a detailed narrative of a negative life event and were then randomly assigned to a rumination or distraction condition. In line with the hypotheses, rumination about the event resulted in the maintenance of negative mood and intrusive memories immediately after the manipulation whereas distraction resulted in symptom reduction. However, this effect was reversed during a subsequent symptom provocation task, in which distraction led to a greater increase in some of the symptoms than rumination. Results are in line with the idea that rumination is involved in the maintenance of PTSD but may suggest a complex relationship between rumination and posttraumatic stress symptoms.
