Development of self-report scales measuring collaborative vs. directive support: Assessing beliefs and behaviors in carers of adults with eating disorders

Michel A. Thibodeau, Josie Geller, Megumi Iyar

Eating Behaviors > 2016 > 23 > C > 156-161

Collaboration is more acceptable and likely to produce favorable outcomes when providing care to individuals with eating disorders compared to directive care. We developed two self-report instruments that assess the extent to which carers (e.g., family, friends) of individuals with eating disorders provide collaborative vs. directive support (Support Behaviors Scale; SBH) and the extent to which carers...

Types and Number of Traumas Associated With Suicidal Ideation and Suicide Attempts in PTSD: Findings From a U.S. Nationally Representative Sample

Daniel M. LeBouthillier, Katherine A. McMillan, Michel A. Thibodeau, Gordon J. G. Asmundson

Journal of Traumatic Stress > 28 > 3 > 183 - 190

Posttraumatic stress disorder (PTSD) is associated with suicidal ideation and suicide attempt; however, research has largely focused on specific samples and a limited range of traumas. We examined suicidal ideation and suicide attempt relating to 27 traumas within a nationally representative U.S. sample of individuals with PTSD. Data were from the National Epidemiologic Survey of Alcohol and Related...

A randomized controlled trial of attention modification for social anxiety disorder

R. Nicholas Carleton, Michelle J.N. Teale Sapach, Chris Oriet, Sophie Duranceau, more

Journal of Anxiety Disorders > 2015 > 33 > C > 35-44

Social Anxiety Disorder (SAD) models implicate social threat cue vigilance (i.e., attentional biases) in symptom development and maintenance. A modified dot-probe protocol has been shown to reduce SAD symptoms, in some but not all studies, presumably by modifying an attentional bias. The current randomized controlled trial was designed to replicate and extend such research. Participants included treatment-seeking...

Do people with and without medical conditions respond similarly to the Short Health Anxiety Inventory? An assessment of differential item functioning using item response theory

Daniel M. LeBouthillier, Michel A. Thibodeau, Nicole M. Alberts, Heather D. Hadjistavropoulos, more

Journal of Psychosomatic Research > 2015 > 78 > 4 > 384-390

Individuals with medical conditions are likely to have elevated health anxiety; however, research has not demonstrated how medical status impacts response patterns on health anxiety measures. Measurement bias can undermine the validity of a questionnaire by overestimating or underestimating scores in groups of individuals. We investigated whether the Short Health Anxiety Inventory (SHAI), a widely-used...

LATENT CLASSES OF NONRESPONDERS, RAPID RESPONDERS, AND GRADUAL RESPONDERS IN DEPRESSED OUTPATIENTS RECEIVING ANTIDEPRESSANT MEDICATION AND PSYCHOTHERAPY

Michel A. Thibodeau, Lena C. Quilty, Filip De Fruyt, Marleen De Bolle, more

Depression and Anxiety > 32 > 3 > 213 - 220

BackgroundWe used growth mixture modeling (GMM) to identify subsets of patients with qualitatively distinct symptom trajectories resulting from treatment. Existing studies have focused on 12‐week antidepressant trials. We used data from a concurrent antidepressant and psychotherapy trial over a 6‐month period. MethodEight hundred twenty‐one patients were randomized to receive either fluoxetine or...

Imagery enhancements increase the effectiveness of cognitive behavioural group therapy for social anxiety disorder: A benchmarking study

Peter M. McEvoy, David M. Erceg-Hurn, Lisa M. Saulsman, Michel A. Thibodeau

Behaviour Research and Therapy > 2015 > 65 > Complete > 42-51

Emerging evidence suggests that imagery-based techniques may enhance the effectiveness of traditional verbal-linguistic cognitive interventions for emotional disorders. This study extends an earlier pilot study by reporting outcomes from a naturalistic trial of an imagery-enhanced cognitive behavioural group therapy (IE-CBGT, n = 53) protocol for social anxiety disorder (SAD), and comparing outcomes...

Revisiting the fundamental fears: Towards establishing construct independence

R. Nicholas Carleton, Michel A. Thibodeau, Jason W. Osborne, Steven Taylor, more

Personality and Individual Differences > 2014 > 63 > Complete > 94-99

Reiss (1991) described three “fundamental” fears-anxiety sensitivity, fear of negative evaluation, and injury/illness sensitivity-as distinct individual differences underlying fearful reactions. Taylor (1993) evidenced the distinctions, but the results have not been replicated despite developments in theory and measures. Intolerance of uncertainty and pain-related anxiety have since been posited as...

The PHQ-9 assesses depression similarly in men and women from the general population

Michel A. Thibodeau, Gordon J.G. Asmundson

Personality and Individual Differences > 2014 > 56 > Complete > 149-153

Gender-based differential item functioning occurs when men and women respond differently to an item despite being similar on the trait assessed by that item. The Patient Health Questionnaire-9 (PHQ-9) is a prominent screening tool for depression. Researchers exploring whether the PHQ-9 exhibits gender-based differential item functioning have used only specialized samples (e.g., individuals with cancer...

ANXIETY DISORDERS ARE INDEPENDENTLY ASSOCIATED WITH SUICIDE IDEATION AND ATTEMPTS: PROPENSITY SCORE MATCHING IN TWO EPIDEMIOLOGICAL SAMPLES

Michel A. Thibodeau, Patrick G. Welch, Jitender Sareen, Gordon J. G. Asmundson

Depression and Anxiety > 30 > 10 > 947 - 954

BackgroundResearch suggests that suicidal behavior in individuals with anxiety disorders is attributable to cooccurring risk factors, such as depression. We argue that these conclusions are founded primarily in statistical adjustments that may obscure independent associations. We explored independent associations between specific anxiety disorders and suicide attempts and ideation by means of propensity...

Psychometric properties of the Obsessive-Compulsive Inventory Revised in African Americans with and without obsessive-compulsive disorder

Monnica Williams, Darlene M. Davis, Michel A. Thibodeau, Nicholas Bach

Journal of Obsessive-Compulsive and Related Disorders > 2013 > 2 > 4 > 399-405

Research has shown that many self-report measures of obsessive-compulsive disorder (OCD) are not valid for certain ethnoracial minority populations. It is important that OCD measures be validated cross-culturally before use in these groups. This study examines the psychometric properties of the Obsessive-Compulsive Inventory Revised (OCI-R) in African Americans (N=148) to establish its validity in...

Validation of the Yale-Brown Obsessive-Compulsive Severity Scale in African Americans with obsessive-compulsive disorder

Monnica T. Williams, Chad T. Wetterneck, Michel A. Thibodeau, Gerardo Duque

Psychiatry Research > 2013 > 209 > 2 > 214-221

The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) is widely used in the assessment of obsessive-compulsive disorder (OCD), but the psychometric properties of the instrument have not been examined in African Americans with OCD. Therefore, the purpose of this study is to explore the properties of the Y-BOCS severity scale in this population. Participants were 75 African American adults with a lifetime...

Pain-related anxiety influences pain perception differently in men and women: A quantitative sensory test across thermal pain modalities

Michel A. Thibodeau, Patrick G. Welch, Joel Katz, Gordon J.G. Asmundson

Pain > 2013 > 154 > 3 > 419-426

The sexes differ with respect to perception of experimental pain. Anxiety influences pain perception more in men than in women; however, there lacks research exploring which anxiety constructs influence pain perception differentially between men and women. Furthermore, research examining whether depression is associated with pain perception differently between the sexes remains scant. The present...

Fear of Injury Predicts Self-Reported and Behavioral Impairment in Patients With Chronic Low Back Pain

Michel A. Thibodeau, Mathew G. Fetzner, R. Nicholas Carleton, Shane S. Kachur, more

Journal of Pain > 2013 > 14 > 2 > 172-181

Fear of injury has been posited as crucial in pain-related anxiety and in the development of chronic pain; however, research has only measured fear of injury indirectly through other constructs (eg, fear of illness and fear of movement). The current study tested fear of injury as an independent contributor to pain-related anxiety and impairment. Patients (n = 78; 37% women) in a work-hardening treatment...

From Higher-Order to Underlying Constructs: Examining the Relationships Between Affect and Fundamental Fears

Michel A. Thibodeau, R. Nicholas Carleton, Kelsey C. Collimore, Gordon J. G. Asmundson

Cognitive Therapy and Research > 2013 > 37 > 2 > 324-331

Targeting constructs that contribute to positive and negative affect may lead to clinically significant reductions in symptoms of principal and co-occurring psychopathology. Anxiety sensitivity, the fear of negative evaluation, and illness/injury sensitivity have been described as three fundamental fears that underlie anxiety-related disorders. Despite the contemporary relevance of the fundamental...

Objective and perceived arousal during performance of tasks with elements of social threat: The influence of anxiety sensitivity

Michel A. Thibodeau, Lydia Gómez-Pérez, Gordon J.G. Asmundson

Journal of Behavior Therapy and Experimental Psychiatry > 2012 > 43 > 3 > 967-974

Physiological arousal serves to maintain social anxiety disorder by skewing self-perception. Anxiety sensitivity is associated with the disorder and exaggerated perceptions of arousal, but has not been tested as explaining exaggerated perceived arousal in social contexts. The aim of this investigation was to address this issue.A total of 42 individuals participated in three tasks associated with potential...

Increasingly certain about uncertainty: Intolerance of uncertainty across anxiety and depression

R. Nicholas Carleton, Myriah K. Mulvogue, Michel A. Thibodeau, Randi E. McCabe, more

Journal of Anxiety Disorders > 2012 > 26 > 3 > 468-479

Intolerance of uncertainty (IU) – a dispositional characteristic resulting from negative beliefs about uncertainty and its implications – may be an important construct in anxiety disorders and depression. Despite the potential importance of IU, clinical data on the construct remains relatively scant and focused on generalized anxiety disorder and obsessive-compulsive disorder. The present study systematically...

Revisiting the latent structure of the anxiety sensitivity construct: More evidence of dimensionality

Gordon J.G. Asmundson, Justin W. Weeks, R. Nicholas Carleton, Michel A. Thibodeau, more

Journal of Anxiety Disorders > 2011 > 25 > 1 > 138-147

Anxiety sensitivity (AS) was initially conceptualized as existing along a continuum; however, emerging evidence from taxometric analyses is mixed as to whether the latent structure of AS is dimensional or taxonic. The purpose of the present study was to further evaluate the latent structure of AS in an effort to clarify the contrasting findings reported in the literature. To do so, we examined the...
