RESUMO
Writing tasks that encourage an appreciation of body functionality can improve women's body image and may buffer against negative effects of idealised media exposure. However, no research has examined whether these tasks can serve as a coping strategy after idealised exposure. To this end, young adult women (N = 217, Mage = 21.63) recruited from an Australian university and general community completed a writing task after idealised media exposure, with state body image measures taken at baseline, post-exposure, and post-task. Women were randomly allocated to one of three writing tasks and asked to appreciate their body functionality, to focus on the previously viewed images (rumination), or to describe a frequently travelled route (distraction). Improvements on outcome measures were equally found across both the functionality and distraction condition. Only body appreciation uniquely improved in the functionality condition. The functionality task was rated more helpful but also more challenging. These findings add to the evidence base regarding the usefulness of functionality-based writing tasks for improving women's body image. They can offer immediate benefits when experiencing body image distress, as can distraction, and future research should explore their utility in driving more sustained and deeper ways of engaging with one's body long-term.
RESUMO
Background: Prior research has shown that inappropriate childhood nurturing experiences (low care and high overprotection), trait anxiety, and depressive rumination are risk factors for depression. However, no studies to date have analyzed the overall association between these factors and depressive symptoms. In the present study, we hypothesized that depressive rumination mediates the impacts of inappropriate childhood nurturing experiences on depressive symptoms, and that these mediating effects are moderated by trait anxiety, and tested these hypotheses in adult volunteers. Methods: The subjects were adult volunteers who were investigated between April 2017 and April 2018. A self-report questionnaire on demographic data, childhood nurturing experiences, trait anxiety, depressive rumination, and depressive symptoms was distributed to conduct the survey, and written informed consent and valid responses were obtained from 585 subjects. Mediation and moderated-mediation analyses were performed by SPSS 28 and macro PROCESS 4.0 software. This study was approved by the Ethics Committee of Tokyo Medical University. Results: Parental care showed a significant negative indirect effect on depressive symptoms via its effect on depressive rumination (p < 0.01), whereas parental overprotection showed the opposite effect (p < 0.01). Furthermore, the mediation effect of depressive rumination on depressive symptoms was increased by trait anxiety (p < 0.05). Conclusion: Our present study demonstrated that the main factor affecting depressive symptoms is inappropriate childhood nurturing experiences, which indirectly enhance depression by intensifying depressive rumination, and that depressive rumination and trait anxiety mutually reinforce each other to enhance depressive symptoms. These findings may be useful for the prevention of depressive symptoms. Large-scale prospective studies are needed to confirm the causal associations among these factors in the future.
RESUMO
In the current article, we describe the development and validation of the Social Comparison Rumination Scale. This measured was developed as a supplement to existing social comparison measures and to enable us to determine its potential relevance to perfectionism and other personality constructs. The Social Comparison Rumination Scale (SCRS) is a six-item inventory assessing the extent to which an individual is cognitively preoccupied and thinking repetitively about social comparison outcomes and information. Three studies with five samples of university students are described. Psychometric analyses established the SCRS consists of one factor assessed with high internal consistency and the measure is reliable and valid. Analyses showed that elevated levels of social comparison rumination are associated with trait perfectionism, perfectionistic automatic thoughts, perfectionistic self-presentation, ruminative brooding, burnout, depression, and fear of negative evaluation. Links were also established between social comparison rumination and both narcissism and dispositional envy. Overall, our findings support the further use of the SCRS and highlight the tendency of many people to think in deleterious ways about social comparisons long after the actual comparisons have taken place. We discuss social comparison rumination within the context of concerns about excessive social media use and young people being exposed to seemingly perfect lives that became a vexing cognitive preoccupation.
RESUMO
In cities, the incidence of mental disorders is higher, while visits to nature have been reported to benefit mental health and brain function. However, there is a lack of knowledge about how exposure to natural and urban environments affects brain structure. To explore the causal relationship between exposure to these environments and the hippocampal formation, 60 participants were sent on a one hour walk in either a natural (forest) or an urban environment (busy street), and high-resolution hippocampal imaging was performed before and after the walks. We found that the participants who walked in the forest had an increase in subiculum volume, a hippocampal subfield involved in stress response inhibition, while no change was observed after the urban walk. However, this result did not withstand Bonferroni correction for multiple comparisons. Furthermore, the increase in subiculum volume after the forest walk was associated with a decrease in self-reported rumination. These results indicate that visits to nature can lead to observable alterations in brain structure, with potential benefits for mental health and implications for public health and urban planning policies.
RESUMO
Laypeople believe that sharing their emotional experiences with others will improve their understanding of those experiences, but no clear empirical evidence supports this belief. To address this gap, we used data from four daily life studies (N = 659; student and community samples) to explore the association between social sharing and subsequent emotion differentiation, which involves labeling emotions with a high degree of complexity. Contrary to our expectations, we found that social sharing of emotional experiences was linked to greater subsequent emotion differentiation on occasions when people ruminated less than usual about these experiences. In contrast, on occasions when people ruminated more than usual about their experiences, social sharing of these experiences was linked to lower emotion differentiation. These effects held when we controlled for levels of negative emotion. Our findings suggest that putting feelings into words through sharing may only enable emotional precision when that sharing occurs without dwelling or perseverating.
RESUMO
This research delves into the correlation between offline bullying and online unethical behavior among college students; and examines the potential mediating influences of anger rumination and perceived relative deprivation. The findings suggest that anger rumination, perceived relative deprivation, offline bullying, and online unethical behavior exhibit significant positive correlations with each other. Offline bullying is a strong predictor of online unethical behavior among college students, with the dual mediating effects of perceived relative deprivation and anger rumination on the relationship between offline bullying and online unethical behavior. This suggests that offline bullying directly influences college students' online unethical behavior and also influences it indirectly through anger rumination and perceived relative deprivation.
RESUMO
Smartphone distraction (SD) is closely related to depression, and the prevalence of SD among nursing students is gradually increasing. However, the potential mechanism of the effect of SD on nursing students' depression is unclear. A total of 574 nursing students were assessed using Smartphone Distraction Scale, Ruminative Response Scale, Hikikomori Questionnaire, and Patient Health Questionnaire-9. The results indicated that SD among nursing students had an impact on depression through four pathways: (1) SD was positively associated with depression (ß = 0.353, P < 0.001); (2) Rumination (ß = 0.199, 95% CI: 0.081 to 0.162) and social withdrawal (ß = 0.061, 95% CI: 0.034 to 0.091) mediated the effects of SD on depression, respectively; and (3) Rumination and social withdrawal played a chain mediating role in the effect of SD on nursing students' depression (ß = 0.027, 95% CI: 0.015 to 0.042). The negative impact of SD on nursing students' mental health should not be taken lightly. Schools and hospitals should guide nursing students to use smartphones correctly, including providing mental health education and professional psychological counselling; families could play a supervisory role and communicate regularly to understand the psychological state and learning of nursing students. These measures can help nursing students cope with stress and reduce the risk of depression.

BACKGROUND/AIMS: The role of neuroticism in predicting nightmare distress have been highlighted, and negative coping style may contribute to this relationship, but how these variables interact is limited. The present study aimed to explore how neuroticism and ruminative response contribute to producing nightmare distress, and to explore whether sex influences this relationship. METHODS: We recruited 758 university students, aged an average of 19.07. A moderated mediation model was built to examine the relationships among neuroticism, rumination, and nightmare distress (measured by dream anxiety scale), and explore whether sex could affect this relationship, using the SPSS PROCESS 3.5 macro. RESULTS: The moderated mediation analyses results showed that ruminative response-depression related can significantly partially mediate the relationship between neuroticism and dream anxiety (ß = 0.32), dream anxiety-sleep-related disturbances (ß = 0.11) and dream anxiety-daytime dysfunctions (ß = 0.21). However, the moderating effects of sex were not significant in all path from neuroticism to dream anxiety. CONCLUSION: The study provides a novel architecture on the underlying psychological mechanisms of neuroticism and nightmare distress. This interplay is assumed to be facilitated by ruminations, suggesting that interventions for individuals who suffer from nightmares may focus on their repetitive negative response strategies, especially in people with high neuroticism, irrespective of sex differences.
RESUMO
Pain, substance use, and mental health conditions are common among people living with HIV (PLWH), and avoidance and rumination may influence the co-occurrence of these conditions. The present study examined longitudinal associations between avoidance/rumination and pain outcomes, anxiety, anger, and substance use among PLWH. Participants (Nâ¯=â¯187) with chronic pain and depressive symptoms completed self-report assessments over a 1-year period. Greater avoidance/rumination was positively associated with mental health outcomes (anxiety, anger), pain interference, and alcohol use across participants after controlling for depression severity. At time points with greater avoidance/rumination than average, participants also reported increased pain severity and interference, anxiety and anger symptoms, and alcohol use. No associations were found between avoidance/rumination and cannabis use. Results suggest a mechanistic effect of avoidance/rumination, such that increases in avoidance/rumination correspond with poorer health outcomes among PLWH over time. Targeting avoidance/rumination through intervention approaches may be beneficial for addressing comorbid health conditions among PLWH. Additional research is necessary to investigate this possibility and further characterize the effects of avoidance/rumination on health outcomes for PLWH.

BACKGROUND AND OBJECTIVES: Friends are major sources of social support for adolescents. This support may sometimes lead to co-rumination when the problem is discussed exhaustively with a focus on negative feelings. Co-rumination has been associated with some forms of anxiety, including clinical symptoms. Further studies are needed to investigate whether this association extends to additional and non-clinical forms of anxiety in youth. This study aimed to explore the relationship between co-rumination and trait anxiety, test anxiety, and anxiety sensitivity using secondary data. DESIGN AND METHODS: In this 2019 cross-sectional study, 1204 (59% girls) Canadian 6th-grade early adolescents (ages 11-12) and 11th-grade late adolescents (ages 16-17) completed self-report questionnaires measuring co-rumination, trait anxiety, test anxiety, and anxiety sensitivity. RESULTS: Co-rumination was associated with anxiety sensitivity in early adolescents and with trait anxiety, test anxiety, and anxiety sensitivity in late adolescents. CONCLUSIONS: Developmental factors may play a role in the association between co-rumination and different forms of anxiety. Anxiety sensitivity may appear alongside co-rumination in early adolescence and may broaden to trait and test anxiety in late adolescence. These results extend our understanding of the relationship between co-rumination and anxiety, as well as generate hypotheses for future longitudinal studies.
RESUMO
BACKGROUND: Repetitive negative thinking (RNT) is a transdiagnostic process involving perseverative, unproductive, and uncontrollable thoughts. Although RNT may impede adaptive psychosocial functioning by prolonging negative mood states, strengthening cognitive biases, and preventing effective problem-solving, the extent to which RNT is associated with risk for poor psychosocial outcomes is unclear. Given that this has clear transdiagnostic treatment implications, the present study aimed to isolate the unique relationship of RNT with social functioning and life satisfaction in a mixed clinical and non-clinical sample. METHODS: In 201 mid-to-later life adult participants (27 with primary diagnoses of bipolar disorder, 84 with major depressive disorder, and 90 healthy volunteers), we measured RNT, social functioning, life satisfaction, trait rumination, DSM-5 diagnoses, depressive symptoms, manic symptoms, cognitive control performance, and global cognitive functioning. RESULTS: Linear regression models revealed that RNT, but not rumination, was significantly associated with poorer social functioning (ßâ¯=â¯0.42 pâ¯<â¯.001) and reduced life satisfaction (ßâ¯=â¯-0.42, pâ¯<â¯.001) after controlling for clinical and cognitive covariates. LIMITATIONS: Limited demographic diversity, cross-sectional design, self-reporting of outcomes. CONCLUSIONS: Results suggest that RNT may confer risk for key psychosocial outcomes during middle to later adulthood, over and above the effects of clinical and cognitive variables and independent of diagnostic status. Findings lend support to the notion of RNT as a transdiagnostic process and suggest that RNT may be an important therapeutic target for adults with poor social functioning and/or reduced life satisfaction.
RESUMO
BACKGROUND: Delivery of preventative interventions via mobile phone apps offers an effective and accessible way to address the global priority of improving the mental health of adolescents and young adults. A proven risk factor for anxiety and depression is elevated worry and rumination, also known as repetitive negative thinking (RNT). OBJECTIVE: This was a prevention mechanism trial that aimed to investigate whether an RNT-targeting self-help mobile phone app (MyMoodCoach) reduces worry and rumination in young adults residing in the United Kingdom. A secondary objective was to test whether the app reduces symptoms of anxiety and depression and improves well-being. METHODS: A web-based, single-blind, 2-arm parallel-group randomized controlled trial was conducted with 236 people aged between 16 and 24 years, who self-reported high levels of worry or rumination. Eligible participants were randomized to an active intervention group (usual practice, plus up to 6 weeks of using the RNT-targeting mobile app, n=119) or a waitlist control group (usual practice with no access to the app until after 6 weeks, n=117). The primary outcome was changes in worry and rumination 6 weeks after randomization. Secondary outcomes included changes in well-being and symptoms of anxiety and depression after 6 weeks and changes in all measures after 12 weeks. RESULTS: Participants randomly allocated to use the RNT-targeting self-help app showed significantly lower levels of rumination (mean difference -2.92, 95% CI -5.57 to -0.28; P=.03; ηp2=0.02) and worry (mean difference -3.97, 95% CI -6.21 to -1.73; P<.001; ηp2=0.06) at 6-week follow-up, relative to the waitlist control. Similar differences were observed for well-being (P<.001), anxiety (P=.03), and depression (P=.04). The waitlist control group also showed improvement when given access to the app after 6 weeks. Improvements observed in the intervention group after 6 weeks of using the app were maintained at the 12-week follow-up point. CONCLUSIONS: The MyMoodCoach app had a significant positive effect on worry and rumination, well-being, anxiety, and depression in young adults, relative to waitlist controls, providing proof-of-principle that an unguided self-help app can effectively reduce RNT. This app, therefore, has potential for the prevention of anxiety and depression although longer-term effects on incidence need to be directly evaluated.

Repetitive negative thinking (RNT) is a transdiagnostic construct that encompasses rumination and worry, yet what precisely is shared between rumination and worry is unclear. To clarify this, we develop a meta-control account of RNT. Meta-control refers to the reinforcement and control of mental behavior via similar computations as reinforce and control motor behavior. We propose rumination and worry are coarse terms for failure in meta-control, just as tripping and falling are coarse terms for failure in motor control. We delineate four meta-control stages and risk factors increasing the chance of failure at each, including open-ended thoughts (stage 1), individual differences influencing subgoal execution (stage 2) and switching (stage 3), and challenges inherent to learning adaptive mental behavior (stage 4). Distinguishing these stages therefore elucidates diverse processes that lead to the same behavior of excessive RNT. Our account also subsumes prominent clinical accounts of RNT into a computational cognitive neuroscience framework.
RESUMO
Background: Rumination is a well-established contributor to the severity of depression and anxiety. It is unknown, however, whether individual differences in the temporal dynamics of rumination over time predict longitudinal increases in depression or anxiety. Methods: The current study examined whether the dynamic indices of ruminative inertia and variability assessed over 14 days via ecological momentary assessment predicted change in symptoms of depression, general anxiety, and social anxiety at a 90-day follow-up (n = 115). Results: Controlling for ruminative variability, baseline levels of the dependent variable, sex, and mean levels of momentary rumination, ruminative inertia did not predict change in symptoms of depression, general anxiety, or social anxiety at the 90-day follow-up. In contrast, greater ruminative variability predicted increases in symptoms of both depression and social anxiety but not general anxiety at follow-up. Individuals endorsing higher baseline levels of depressive symptoms demonstrated greater amounts of inertia and variability in their momentary rumination. Greater ruminative variability but not inertia was also associated with higher baseline levels of general anxiety and social anxiety. Conclusions: These results suggest that ruminative variability may be a risk factor for increases in symptoms of depression and social anxiety over time and a potentially useful target for clinical intervention.
RESUMO
Treatment-resistant depression (TRD) is defined as patients diagnosed with depression having a history of failure with different antidepressants with an adequate dosage and treatment duration. The NMDA receptor antagonist ketamine rapidly reduces depressive symptoms in TRD. We examined neural correlates of treatment response to ketamine in TRD through a systematic review of brain magnetic resonance imaging (MRI) studies. A comprehensive search in PubMed was performed using "ketamine AND depression AND magnetic resonance." The time span for the database queries was "Start date: 2018/01/01; End date: 2024/05/31." Total 41 original articles comprising 1,396 TRD and 587 healthy controls (HC) were included. Diagnosis of depression was made using the Structured Clinical Interview for DSM Disorders (SCID), the Mini-International Neuropsychiatric Interview (MINI), and/or the clinical assessment by psychiatrists. Patients with affective psychotic disorders were excluded. Most studies applied ketamine [0.5mg/kg racemic ketamine and/or 0.25mg/kg S-ketamine] diluted in 60cc of normal saline via intravenous infusion over 40 min one time, four times, or six times spaced 2-3 days apart over 2 weeks. Clinical outcome was defined as either remission, response, and/or percentage changes of depressive symptoms. Brain MRI of the T2*-weighted imaging (resting-state or task performance), arterial spin labeling, diffusion weighted imaging, and T1-weighted imaging were acquired at baseline and mainly 1-3days after the ketamine administration. Only the study results replicated by ≥ 2 studies and were included in the default-mode, salience, fronto-parietal, subcortical, and limbic networks were regarded as meaningful. Putative brain-based markers of treatment response to ketamine in TRD were found in the structural/functional features of limbic (subgenual ACC, hippocampus, cingulum bundle-hippocampal portion; anhedonia/suicidal ideation), salience (dorsal ACC, insula, cingulum bundle-cingulate gyrus portion; thought rumination/suicidal ideation), fronto-parietal (dorsolateral prefrontal cortex, superior longitudinal fasciculus; anhedonia/suicidal ideation), default-mode (posterior cingulate cortex; thought rumination), and subcortical (striatum; anhedonia/thought rumination) networks. Brain features of limbic, salience, and fronto-parietal networks could be useful in predicting the TRD with better response to ketamine in relief of anhedonia, thought rumination, and suicidal ideation.
RESUMO
Life satisfaction refers to an individual' s cognitive evaluation of the overall quality of their life considering the various aspects therein. Although the existing research has demonstrated the between-person relationship between negative life events and life satisfaction based on retrospective measures, less is known about this relationship at the within-person level. A daily diary method could examine this within-person relationship and decrease systematic recall biases. Therefore, this study investigated the link between daily negative life events and daily life satisfaction, as well as the mediating role of perceived stress and the moderating role of trait rumination in 146 young adults (Mage = 20.75, SD = 1.35) using a 14-day daily diary design. Multilevel regression analysis showed that daily negative life events had negative predictive effects on daily life satisfaction. In addition, the multilevel 1-1-1 mediation analysis indicated that daily perceived stress mediated the association between daily negative life events and daily life satisfaction. More importantly, the mediating effect of perceived stress was moderated by trait rumination, with the within-person mediating effect being stronger for individuals with higher than those with lower trait rumination tendencies. These findings contribute to the understanding of the underlying pathways in the relationship between daily negative life events and daily life satisfaction and provide a new perspective for improving individuals' life satisfaction.
RESUMO
OBJECTIVES: Rumination syndrome (RS) is challenging to diagnose, which can lead to diagnostic delays. Our objective was to evaluate the length of time from RS symptom onset to diagnosis in patients referred to our institution and to examine whether this duration predicts treatment outcomes. METHODS: We conducted a review of patients with RS evaluated at our institution. Data were collected from chart review and patient/family reported questionnaires. We evaluated the time from symptom onset to diagnosis over time and whether it was associated with symptom resolution. RESULTS: We included 247 patients with RS (60% female, median age of 14 years, interquartile range [IQR]: 9-16 years). The median age at symptom onset was 11 years (IQR: 5-14 years) and median age at diagnosis was 13 years (IQR: 9-15 years) for a median duration of 1 year (IQR: 0-3 years) between symptom onset and diagnosis. Length of time between symptom onset and diagnosis did not change significantly at our institution from 2016 to 2022. Among the 164 children with outcome data, 47 (29%) met criteria for symptom resolution after treatment. A longer time to diagnosis was associated with a lower likelihood of symptom resolution after treatment (p = 0.01). CONCLUSION: In our experience, the time to RS diagnosis after symptom onset is shorter than previously described. A longer delay in diagnosis is associated with lower likelihood of symptom resolution after treatment, emphasizing the importance of a prompt recognition of rumination symptoms and a timely diagnosis.
RESUMO
OBJECTIVE: To explore the associations between childhood trauma, alexithymia, rumination, and non-suicidal self-injury (NSSI) among adolescents and to provide theoretical and empirical evidence for effective prevention, identification, and intervention of NSSI in the future. METHODS: Questionnaires, including the Childhood Trauma Questionnaire, the twenty-item Toronto Alexithymia scale, the Ruminative Responses Scale, and the Adolescents Self-Harm Scale, were given to 1,270 Chinese teenagers. The mediating role was simulated utilizing Amos 24.0. RESULTS: The Pearson's product-difference correlation analyses indicated the two-by-two significant correlations between childhood trauma, alexithymia, rumination, and NSSI. The structural equation modeling suggests that alexithymia and rumination partially mediate between childhood trauma and NSSI in teenagers, respectively. Additionally, it reveals that alexithymia and rumination chain mediate between childhood trauma and NSSI. CONCLUSION: The study confirms the impact of childhood trauma on adolescents' NSSI and also highlights the mediating role of alexithymia and rumination between the two. This study enriches the findings of NSSI and provides a theoretical basis for preventing and intervening in dysfunctional behaviors among adolescents.
RESUMO
Background: Mental disorders in university students are a growing attention problem in the international community due to their high prevalence and serious consequences. One possible reason is university students' difficulties in coping with stress. Repetitive negative thinking (RNT) is a transdiagnostic process that, when combined with stress, can lead to the development of various disorders. We aim to determine the effect of stress and RNT on predicting various mental health syndromes in university students across 7 days. Method: Prospective observational study using Momentary Ecological Assessment (EMA) with the OURMIND Mobile App. On day one, 238 university students responded to the SCL-90R questionnaire for symptoms of depression, anxiety, hostility, obsession, psychoticism, paranoia, somatization, and interpersonal sensitivity; RNT styles questionnaires, RRS for rumination and negative reflection, PSWQ for worry; SISCO-II for term academic stress, and sociodemographic. EMA consisted of five assessments a day for 6 days; each time, the students answered items about academic and non-academic stress (EMA-stress), reactive RNT duration and intrusiveness (EMA-RNT process), and reactive RNT rumination, reflection, and worry (EMA-RNT content). On day eight, symptoms were re-assessed. Seven hierarchical stepwise linear regression models were used to test the predictive power of the study variables in the development of SCL-90R symptoms. Results: When comparing models, adding baseline symptoms increased the models' predictive power in all symptom groups. In most cases, including EMA-stress generated greater predictive power, except for paranoia and interpersonal sensitivity. Adding the EMA-RNT process increased the prediction of paranoia and obsessive symptoms; for hostility symptoms, RNT styles increased predictive power. For the final regression models, considering the initial symptoms, the EMA-RNT process predicted the progression of symptoms in six out of eight groups, while EMA-non-academic stress predicted the remaining two. Additionally, living with other relatives or friends was a predictor of depressive symptoms. Discussion: The stress of university life impacts the development of psychiatric symptoms in university students. These results provide evidence of RNT as a transdiagnostic process in several syndromic groups. Universal preventive programs should consider the impact of academic and non-academic stress on university students' mental health. Targeting RNT would also benefit selective preventive interventions.
RESUMO
BACKGROUND: In this study, we re-examined data from a previous randomized controlled trial investigating 'technology supported mindfulness' (TSM)-an 8-week treatment intervention for individuals experiencing OCD. The current analysis involves an examination of the longitudinal relationships between rumination, worry and OCD symptom changes during mindfulness treatment, in comparison to a waitlist control. METHODS: Participants experiencing OCD (n = 71) were randomly assigned to 8 weeks of (1) TSM or (2) waitlist control. We tested the extent to which rumination (using the Ruminative Response Scale) and worry (using the Penn State Worry Questionnaire) are associated with OCD symptom changes during the acute phase of treatment, concurrently (i.e., within the same longitudinal model). RESULTS: Generalized linear model (GLM) results indicated a significant time (week 1 vs. week 8) by condition interaction involving decreased rumination in the TSM condition: F(1, 61) = 13.37, p = 0.001, partial η2 = 0.18 and observed power = 0.94. A second GLM demonstrated decreased worry in the TSM condition: F(1, 69) = 37.34, p = 0.001, partial η2 = 0.35 and observed power = 0.83. Longitudinal 'latent difference' structural equation analyses demonstrated a cross-lagged association between worry (but not rumination) and OCD symptom changes. CONCLUSIONS: Individuals in the TSM condition experienced greater reductions in rumination and worry during 8 weeks of TSM treatment compared to the waitlist control, and reduced worry predicted subsequent OCD symptom reduction.
