RESUMO

BACKGROUND AND OBJECTIVES: Rituals are common among healthy individuals and across cultures and often serve adaptive purposes. In individuals with obsessive-compulsive disorder (OCD), rituals become compulsive, time-consuming and distressing, and may lead to functional impairment. Previous research has examined the functions and characteristics of compulsive rituals, but there is paucity of in-depth, first-person reports about this topic. METHOD: We used a qualitative approach to explore thoughts, feelings, and behavioral patterns that characterize OCD rituals. Ten individuals with OCD participated in a semi-structured interview that focused on their most prominent compulsive ritual. The interviews were subjected to a thematic analysis. RESULTS: Eight themes emerged from the analysis and were organized in two main categories: Micro Level perspective, comprising triggers, attention, emotional changes, and stopping criteria; and Macro Level perspective, comprising feelings and perceptions, change over time, motives, and inhibitors. The findings shed light on the role of fixed rules and feelings of "completeness" in OCD rituals, the nature of emotional and attentional characteristics during rituals performance, and the evolution of compulsive rituals over time. LIMITATIONS: This study used a qualitative approach based on a small number of participants, which limits the generalizability of the findings. CONCLUSION: Our results, if replicated, may have clinical implications. The reported patterns of anxiety reduction during ritual performance may contribute to the fine-tuning of CBT for OCD. The findings concerning the nature of attention during ritual performance and the development of rituals over time may be important for understanding the mechanisms that maintain compulsive rituals.

RESUMO

BACKGROUND: Anxiety sensitivity (AS) and disgust sensitivity (DS) are transdiagnostic vulnerability factors for anxiety. Both correlate with blood-injection-injury (BII) phobia symptoms in several studies; however, there is ambiguity about their relative contributions, and studies investigating this have relied on unselected samples. Furthermore, although DS reliably predicts BII in studies that do not account for AS, this may be limited to domain-specific DS rather than DS more broadly. AIMS: The aims of this study were to examine AS and DS as separate and simultaneous predictors of BII fears in a sample with a wide range of BII symptoms, and with attention to the specificity of DS to BII-relevant domains. METHOD: Fifty-three participants who scored above a clinical threshold on a validated measure of dental anxiety, and who represented a wide range of BII severity, completed measures of AS, DS and BII symptoms. RESULTS: AS and DS were moderately to strongly correlated with BII severity (r = .40 and .47, p = .004 and <.001), and both independently predicted BII severity when entered as simultaneous predictors (ß = .32 and .35, p = .045 and .015). Furthermore, after omitting DS about injections and blood draws, domain-general DS was still moderately correlated with BII severity (r = .33, p = .017). However, domain-general DS did not significantly predict BII severity after accounting for AS (ß = .20, p = .164). CONCLUSIONS: AS and DS both predict BII symptoms, and prospective research is warranted to examine them as potential vulnerability factors.

RESUMO

The COVID-19 pandemic poses unique risks to college students' mental health, and specifically to symptoms of obsessive-compulsive disorder (OCD). To better understand the relationship between COVID-19 impact and OC symptoms in this population, six colleges from across the US administered a battery of questionnaires and an emotion differentiation paradigm to eligible students (N = 841). We examined whether degree of pandemic-related disruption was associated with OC severity, and if so, whether this relationship was explained by trait (poor emotion regulation and differentiation) and state risk factors (poor sleep quality, less exercise frequency, less social support, thwarted sense of belongingness, and greater loneliness). Results indicated that the positive relationship between COVID-19 impact and OC severity was mediated by trait emotion-related processes (e.g., emotion regulation and differentiation), but no state risk factors emerged as significant mediators. Our findings contribute to the literature demonstrating a significant relationship between COVID-19 impact and OC severity, and highlight that emotion regulation difficulties may help explain this association. Our findings can inform evidence-based interventions on college campuses; however, the cross-sectional design precludes causal inferences. Future research should evaluate these relationships longitudinally and incorporate other psychosocial factors that may operate as mechanisms.

RESUMO

Grit is associated with positive outcomes in nonclinical samples. However, no studies have examined grit in relation to psychopathology in patients with clinical mood or anxiety disorders. Research and clinical experience suggest that individuals who hoard struggle with characteristics associated with grit, such as task persistence, impulsivity, and self-control. The authors tested the hypothesis that hoarding symptoms are associated with less grit in a sample of individuals (N = 72) presenting for treatment to an anxiety disorders clinic. After covarying symptoms of the four mood and anxiety disorders most commonly comorbid with hoarding disorder (viz. depression, generalized anxiety, social anxiety, and obsessive-compulsive disorder), the authors found that hoarding symptoms were associated with less grit, and the effects were medium-to-large. These results indicate that grit is worthy of investigation in individuals with hoarding disorder using methodologies that permit inferences about causality, and with attention to clinical implications for prevention or treatment.

RESUMO

Individuals with dental anxiety show biased attentional processing of threat- and dental-related information. Disgust sensitivity and anxiety sensitivity are both associated with dental fears and attentional biases. Whereas disgust sensitivity is generally associated with attentional avoidance (Armstrong et al., 2014), anxiety sensitivity may be associated with attentional engagement (Keogh et al., 2001a). Elucidating the role of these constructs in dental anxiety-relevant attentional biases could inform theoretical models and/or intervention recommendations. Participants (N = 51) with high dental anxiety completed a Posner paradigm to assess attentional biases to dental versus neutral stimuli. We examined whether disgust sensitivity and anxiety sensitivity moderated degree of attentional bias. Results indicated that both disgust sensitivity (mutilation subscale) and anxiety sensitivity (physical concerns subscale) statistically moderated degree of attentional bias at trend level, and in opposite directions. Simple effects analyses further indicated that disgust sensitivity regarding mutilation was associated with less attentional bias toward dental relative to neutral stimuli, potentially indicating attentional avoidance, and remained so when adjusting for anxiety sensitivity. In contrast, simple effects analysis indicated that anxiety sensitivity regarding physical concerns was not associated with magnitude of attentional bias. If replicated, findings highlight the potential role of disgust in dental anxiety.

RESUMO

BACKGROUND: People with obsessive-compulsive disorder (OCD) have faced unique challenges during the COVID-19 pandemic. Research from the first two months of the pandemic suggests that a small proportion of people with OCD experienced worsening in their OCD symptoms since the pandemic began, whereas the rest experienced either no change or an improvement in their symptoms. However, as society-level factors relating to the pandemic have evolved, the effects of the pandemic on people with OCD have likely changed as well, in complex and population-specific ways. Therefore, this study contributes to a growing body of knowledge on the impact of the COVID-19 pandemic on people and demonstrates how differences across studies might emerge when studying specific populations at specific timepoints. OBJECTIVE: This study aimed to assess how members of online OCD support communities felt the COVID-19 pandemic had affected their OCD symptoms, around 3 months after the pandemic began. METHODS: We recruited participants from online OCD support communities for our brief survey. Participants indicated how much they felt their OCD symptoms had changed since the pandemic began and how much they felt that having OCD was making it harder to deal with the pandemic. RESULTS: We collected survey data from June through August 2020 and received a total of 196 responses, some of which were partial responses. Among the nonmissing data, 65.9% (108/164) of the participants were from the United States and 90.5% (152/168) had been subjected to a stay-at-home order. In all, 92.9% (182/196) of the participants said they experienced worsening of their OCD symptoms since the pandemic began, although the extent to which their symptoms worsened differed across dimensions of OCD; notably, symmetry and completeness symptoms were less likely to have worsened than others. Moreover, 95.5% (171/179) of the participants felt that having OCD made it difficult to deal with the pandemic. CONCLUSIONS: Our study of online OCD support community members found a much higher rate of OCD symptom worsening than did other studies on people with OCD conducted during the current COVID-19 pandemic. Factors such as quarantine length, location, overlapping society-level challenges, and differing measurement and sampling choices may help to explain this difference across studies.

RESUMO

OBJECTIVE: Scrupulosity is a manifestation of obsessive-compulsive disorder (OCD) characterized by religious or moral core fears. Clinicians often struggle to treat scrupulosity, which may be associated with several features known to predict poor treatment outcome. The purpose of this study was to examine these features in participants with scrupulous OCD, contamination OCD, and healthy controls. METHOD: A total of 68 participants (57.4% women, agemean = 34.01) completed diagnostic interviews, and measures of symptoms and quality-of-life. RESULTS: Relative to comparison groups, scrupulous participants had higher rates of obsessive-compulsive personality disorder, more severe schizotypal symptoms, and more severe symptoms of depression. In addition, OCD severity was strongly associated with poor insight in the scrupulous group. Both OCD groups reported poorer quality of life than did healthy controls. CONCLUSIONS: Clinicians working with scrupulous individuals may enhance the efficacy of treatment in this challenging population by assessing carefully for these features, and incorporating treatment elements that address them.

RESUMO

OBJECTIVE: Body image disturbance (BID) is common among women, characterized by persistent and distressing appearance dissatisfaction, and linked with eating disorders. Although effective, cognitive behavioral therapy (CBT) delivered by trained professionals is not easily accessible. This randomized trial evaluated the effects of a CBT-based mobile application designed to increase resilience to body image triggers and reduce BID symptoms. METHOD: A non-clinical sample of women (N = 90; Mage = 23.52) was randomized to use the mobile application for approximately 4 min of daily exercises for two weeks or to a control condition. Body image was measured at baseline, immediately after two weeks of mobile application use, and at 1-month follow-up. To examine whether using the application was associated with increased resilience to common BID triggers, participants completed an Instagram exposure resilience task upon completion and at 1-month follow-up. RESULTS: Relative to those in the control condition, participants who used the application demonstrated increased resiliency and reduced BID symptoms. Theses effects were medium-to-large and were maintained at 1-month follow-up. CONCLUSION: These results underscore the potential usefulness of brief, low-intensity, portable interventions in reducing BID symptoms and in increasing resilience to thin-ideal body messages often portrayed on social media.

RESUMO

Dental anxiety is common and associated with negative outcomes. According to information-processing models, anxiety is maintained by maladaptive patterns of processing threatening information. Furthermore, attention training interventions can reduce anxiety in one session. Fifty-three individuals with high levels of dental anxiety completed a Posner reaction-time task. Participants were randomized to attention training or control using a dot-probe task, and then attentional bias was remeasured using another Posner task. Participants then completed a script-driven imaginal exposure task. Results indicated that individuals high in dental anxiety exhibit threat-relevant attentional bias. There was mixed evidence about the efficacy of attention training. On the one hand, training did not eliminate attentional bias and training condition did not predict distress during the imagery task. On the other hand, cue dependency scores in the control group were higher for dental than neutral cues, but did not differ in the training group. In addition, cue dependency scores for both dental and neutral cues predicted subjective anxiety in anticipation of the imagery task. The mixed results of training are considered in terms of the possibility that it enhanced attentional control, rather than reducing bias.

RESUMO

Status-based rejection sensitivity refers to the anxious expectation and tendency to perceive rejection in ambiguous social scenarios based on one's minority identification. This study evaluates the implications of sensitivity to rejection based on sexual orientation identity on negative mental health outcomes. Current minority stress models include rejection sensitivity as a factor that may contribute to adverse negative psychosocial outcomes in LGBT persons. This study evaluates the role of rejection sensitivity alongside demographically relevant predictors such as age, race, education, and level of sexuality disclosure in predicting the presence of significant depression and anxiety scores among a sample of gay men. Results indicate that rejection sensitivity, sexuality openness, and anxiety were significant predictors of depression symptoms, whereas age and depression were significant predictors of anxiety symptoms. This study supports the role of rejection sensitivity as a contributor to negative mental health outcomes among gay men, particularly as it pertains to internalizing mental health disorders.

RESUMO

There is conflicting evidence as to whether military populations (i.e., veteran and active-duty military service members) demonstrate a poorer response to psychotherapy for posttraumatic stress disorder (PTSD) compared to civilians. Existing research may be complicated by the fact that treatment outcomes differences could be due to the type of trauma exposure (e.g., combat) or population differences (e.g., military culture). This meta-analysis evaluated PTSD treatment outcomes as a function of trauma type (combat v. assault v. mixed) and population (military v. civilian). Unlike previous meta-analyses, we focused exclusively on manualized, first-line psychotherapies for PTSD as defined by expert treatment guidelines. Treatment outcomes were large across trauma types and population; yet differences were observed between trauma and population subgroups. Military populations demonstrated poorer treatment outcomes compared to civilians. The combat and assault trauma subgroups had worse treatment outcomes compared to the mixed trauma subgroup, but differences were not observed between assault and combat subgroups. Higher attrition rates predicted poorer treatment outcomes, but did not vary between military populations and civilians. Overall, manualized, first-line psychotherapies for PTSD should continue to be used for civilians and military populations with various trauma types. However, greater emphasis should be placed on enhancing PTSD psychotherapies for military populations and on treatment retention across populations based on findings from this meta-analysis.

RESUMO

Cognitive (CT) and behavioral treatments (BT) for OCD are efficacious separately and in combination. Tailoring treatment to patient-level predictors and moderators of outcome has the potential to improve outcomes. The present study combined data from eight treatment clinics to examine the benefits of BT (n = 125), CT (n = 108), and CBT (n = 126), and study predictors across all treatments and moderators of outcome by treatment type. All three methods led to large benefits for OCD and depression symptoms. Residual gain scores for OCD symptoms were marginally smaller for BT compared to treatments containing CT. For depression, significantly more gains were evident for CBT than BT, and CT did not differ from either. Significantly fewer BT participants (36%) achieved clinically significant improvement compared to CT (56%), and this was marginally evident for CBT (48%). For all treatments combined, no predictors were identified in residual gain analyses, but clinically improved patients had lower baseline depression and stronger beliefs about responsibility/threat and importance/control of thoughts. Moderator analyses indicated that higher baseline scores on depression adversely affected outcomes for BT but not CT or CBT, and lower OCD severity and more education were associated with positive outcomes for CT only. A trend was evident for higher responsibility/threat beliefs to moderate clinical improvement outcomes for those receiving cognitive (CT and CBT), but not behavioral (BT) treatment. Medication status and comorbidity did not predict or moderate outcomes. Findings are discussed in light of models underlying behavioral and cognitive treatments for OCD.

RESUMO

Obsessive-compulsive disorder (OCD) includes many symptom presentations, which creates unique diagnostic challenges. Fears surrounding one's sexual orientation are common within OCD (also called SO-OCD), but SO-OCD is consistently misdiagnosed by physicians and psychologists. To address this issue, we describe the development of a self-report measure for assessing SO-OCD to help distinguish OCD from distress caused by a sexual orientation identity crisis. The current paper details two studies that established the psychometric properties and clinical utility of this measure. In Study 1, the factor structure, validity, and reliability were examined for the measure's 12 items in a sample of 1,673 university students. The results revealed a two-factor solution for the measure (Factor 1: Transformation Fears; Factor 2: Somatic Checking) and preliminary evidence of validity and reliability. In Study 2, the measure was tested with LGBTQ and heterosexual community samples and clinical samples of individuals with SO-OCD and other types of OCD. The two-factor solution and evidence of validity and reliability were supported in these samples. Cut-off points were established to distinguish between community members and SO-OCD sufferers, as well as between those experiencing SO-OCD and other types of OCD. Limitations and future directions are discussed.

RESUMO

Disgust has been shown to perform a "disease-avoidance" function in contamination fears. However, no studies have examined the relevance of disgust to obsessive-compulsive (OC) concerns about sexual orientation (e.g., fear of one's sexual orientation transforming against one's will, and compulsive avoidance of same-sex and/or gay or lesbian individuals to prevent that from happening). Therefore, we investigated whether the specific domain of contamination-based disgust (i.e., evoked by the perceived threat of transmission of essences between individuals) predicted OC concerns about sexual orientation, and whether this effect was moderated/amplified by obsessive beliefs, in evaluation of a "sexual orientation transformation-avoidance" function. We recruited 283 self-identified heterosexual college students (152 females, 131 males; mean age = 20.88 years, SD = 3.19) who completed three measures assessing disgust, obsessive beliefs, and OC concerns about sexual orientation. Results showed that contamination-based disgust (ß = .17), responsibility/threat overestimation beliefs (ß = .15), and their interaction (ß = .17) each uniquely predicted OC concerns about sexual orientation, ts = 2.22, 2.50, and 2.90, ps < .05. Post hoc probing indicated that high contamination-based disgust accompanied by strong responsibility/threat overestimation beliefs predicted more severe OC concerns about sexual orientation, ß = .48, t = 3.24, p < .001. The present study, therefore, provided preliminary evidence for a "sexual orientation transformation-avoidance" process underlying OC concerns about sexual orientation in heterosexual college students, which is facilitated by contamination-based disgust, and exacerbated by responsibility/threat overestimation beliefs. Treatment for OC concerns about sexual orientation should target such beliefs.

RESUMO

The picture of suicide in obsessive-compulsive disorder (OCD) is unclear because previous research did not uniformly control for depressive symptoms when examining the relationship between OCD and suicidality. Specific links between OC symptom dimensions and suicidality were also not adequately studied. As such, we investigated specific associations between OC symptom dimensions and suicidality, beyond the contribution of depressive symptoms, in an OCD analog sample of college students, a group traditionally at risk for suicide. One hundred and forty-six college students (103 females; 43 males) who exceeded the clinical cut-off for OC symptoms on the Obsessive-Compulsive Inventory, Revised (OCI-R) were recruited. Participants completed an online questionnaire containing measures that assessed suicidality and OC and depressive symptom severity. Total OC symptom severity, unacceptable thoughts, and especially violent obsessions exhibited significant positive zero-order correlations with suicidality. However, analyses of part correlations indicated that only violent obsessions had a significant unique association with suicidality after controlling for depressive symptoms. Our findings support the hypothesis that violent obsessions have a specific role in suicidality beyond the influence of depressive symptoms in an OCD analog sample of college students. A strong clinical focus on suicide risk assessment and safety planning in college students reporting violent obsessions is therefore warranted. Future related research should employ longitudinal or prospective designs and control for other possible comorbid symptoms in larger and more representative samples of participants formally diagnosed with OCD in order to verify the generalizability of our findings to these groups.

RESUMO

BACKGROUND AND OBJECTIVES: Prior research has indicated a number of neuropsychological deficits in patients with OCD consistent with the cortico-striato-thalamo-cortical model of the disorder. Response inhibition (RI), defined as the inability to inhibit a prepotent response, has been identified as a possible candidate endophenotype for OCD. However, the results from previous studies of RI in OCD patients have been mixed, suggesting the possibility that some OCD dimensions may be associated with deficits in RI while others may not. The present study aimed to examine RI using a Go/No-Go (GNG) task in two OCD symptom dimensions, one of which, scrupulosity, has never been subject to neuropsychological investigation. METHODS: A total of 63 individuals, consisting of scrupulous OCD (n = 26), contamination OCD (n = 18) and non-psychiatric controls (n = 19) completed study measures. Controlling for depression symptoms, no significant performance differences were found between the groups on the GNG test, indicating no deficits in RI among contamination or scrupulous OCD. RESULTS: Results are consistent with several prior studies of RI in OCD that found no differences as compared to non-psychiatric controls, especially on GNG tests, and with more recent suggestions that RI may not constitute a clinical significant impaired domain in OCD. LIMITATIONS: Limitations included a primarily highly educated and Caucasian sample. CONCLUSIONS: Additional conclusions include careful consideration of the RI measures selected for future studies, as well as the need for further investigation into the neuropsychological and neurobiological nature of scrupulous OCD.

RESUMO

Sexual obsessions are a common symptom of obsessive-compulsive disorder (OCD), often classified in a broader symptom dimension that includes aggressive and religious obsessions, as well. Indeed, the Dimensional Obsessive-Compulsive Scale (DOCS) Unacceptable Thoughts Scale includes obsessional content relating to sexual, violent, and religious themes associated with rituals that are often covert. However, there is reason to suspect that sexual obsessions differ meaningfully from other types of unacceptable thoughts. We conducted two studies to evaluate the factor structure, initial psychometric characteristics, and associated clinical features of a new DOCS scale for sexually intrusive thoughts (SIT). In the first study, nonclinical participants (N=475) completed the standard DOCS with additional SIT questions and we conducted an exploratory factor analysis on all items and examined clinical and cognitive correlates of the different scales, as well as test-retest reliability. The SIT Scale was distinct from the Unacceptable Thoughts Scale and was predicted by different obsessional cognitions. It had good internal consistency and there was evidence for convergent and divergent validity. In the second study, we examined the relationships among the standard DOCS and SIT scales, as well as types of obsessional cognitions and symptom severity, in a clinical sample of individuals with OCD (N=54). There were indications of both convergence and divergence between the Unacceptable Thoughts and SIT scales, which were strongly correlated with each other. Together, the studies demonstrate the potential utility of assessing sexually intrusive thoughts separately from the broader category of unacceptable thoughts.

RESUMO

Tourette's disorder, also called Tourette syndrome (TS), is characterized by motor and vocal tics that can cause significant impairment in daily functioning. Tics are believed to be due to failed inhibition of both associative and motor cortico-striato-thalamo-cortical pathways. Comprehensive Behavioral Intervention for Tics (CBIT), which is an extension of Habit Reversal Therapy (HRT), teaches patients to become more aware of sensations that reliably precede tics (premonitory urges) and to initiate competing movements that inhibit the occurrence of tics. In this study, we used functional magnetic resonance imaging (fMRI) to investigate the neural changes associated with CBIT treatment in subjects with TS. Eight subjects with TS were matched with eight healthy controls in gender, education, age, and handedness. Subjects completed the Visuospatial Priming (VSP) task, a measure of response inhibition, during fMRI scanning before and after CBIT treatment (or waiting period for controls). For TS subjects, we found a significant decrease in striatal (putamen) activation from pre- to post-treatment. Change in VSP task-related activation from pre- to post-treatment in Brodmann's area 47 (the inferior frontal gyrus) was negatively correlated with changes in tic severity. CBIT may promote normalization of aberrant cortico-striato-thalamo-cortical associative and motor pathways in individuals with TS.

RESUMO

OBJECTIVES: Scrupulosity is a relatively common but understudied subtype of obsessive-compulsive disorder (OCD) characterized by religious or moral fears. It is difficult to treat and frequently disabling. We examined scrupulosity as it relates to (a) treatment-seeking behavior and perceived treatment gains, (b) the perceived effect of symptoms on religious experience, and (c) conceptions of God. METHOD: Seventy-two individuals with scrupulous OCD (mean age = 36; 70% women) and 75 individuals with nonscrupulous OCD (mean age = 38; 81% women) completed an internet-based survey. RESULTS: The groups did not differ on demographic variables or overall OCD severity. Compared with the nonscrupulous group, the scrupulous group was (a) more religious, (b) more likely to seek pastoral counseling, (c) less likely to seek medication treatment, and (d) more likely to report that symptoms interfered with their religious experience. Indeed, most scrupulous individuals endorsed that their symptoms interfered with their religious experience. Scrupulous individuals with a more negative concept of God experienced more severe symptoms, whereas a positive description of God was unrelated to severity of scrupulosity in this group. Nearly one in five scrupulous participants reported no religious affiliation. CONCLUSIONS: Scrupulous individuals have unique treatment-seeking preferences. Moreover, most scrupulous individuals perceive their symptoms as interfering with their religious experience. Focusing on the religious costs and benefits of scrupulous rituals might have clinical utility. Finally, scrupulous individuals with a more negative concept of God experienced more severe symptoms. Future research is necessary to evaluate whether addressing such concepts can improve treatment outcome.

RESUMO

OBJECTIVE: Whether social support is associated with severity of body dysmorphic symptoms is unknown. To address this gap in the literature, the present study aims to examine the association between three domains of perceived social support (i.e., family, friends, and significant others) and severity of body dysmorphic disorder symptoms. METHOD: Participants (N = 400) with symptoms consistent with diagnosis of body dysmorphic disorder completed measures of symptomatology and social support via the internet. RESULTS: More perceived social support from friends and significant others was associated with less severe body dysmorphic disorder symptoms for males, and more perceived social support from family and friends was associated with less severe body dysmorphic disorder symptoms among females. Additionally, gender moderated the association between perceived social support from significant others and symptom severity, such that perceived social support from a significant other was significantly negatively associated with body dysmorphic symptom severity in males, but not females. CONCLUSION: The present study implicates social support as an important area of future body dysmorphic disorder research.
