Cognitive behavioral therapy-related increases in cortical inhibition in problematic perfectionists

Overall goal of Cognitive-Behavioral Therapy in Major Psychiatric Disorders and Suicidality: A Narrative Review

Cognitive-behavioral therapy (CBT) is a form of psychological treatment that is based on the underlying assumption that mental disorders and psychological distress are maintained by cognitive factors, that is, that general beliefs about the world, the self, and the future contribute to the maintenance of emotional distress and behavioral problems. The overall goal of CBT is to replace dysfunctional constructs with more flexible and adaptive cognitions. The most relevant cognitive-behavioral techniques in clinical practice are: i. Cognitive Restructuring (also known as the ABCDE method) is indicated to support patients dealing with negative beliefs or thoughts. The different steps in the cognitive restructuring process are summarized by the letters in the ABCDE acronym that describe the different stages of this coaching model: Activating event or situation associated with the negative thoughts, Beliefs and belief structures held by the individual that explain how they perceive the world which can facilitate negative thoughts, Consequences or feelings related to the activating event, Disputation of beliefs to allow individuals to challenge their belief system, and Effective new approach or effort to deal with the problem by facilitating individuals to replace unhelpful beliefs with more helpful ones. ii. Problem-Solving (also known as SOLVE) to raise awareness for specific triggers, and evaluate and choose more effective options. Each letter of the SOLVE acronym identifies different steps of the problem-solving process: Select a problem, generate Options, rate the Likely outcome of each option, choose the Very best option, and Evaluate how well each option worked. For example, a suicide attempt is reconceptualized as a failure in problem-solving. This treatment approach attempts to provide patients with a better sense of control over future emerging problems. iii. Re-attribution is a technique that enables patients to replace negative self-statements (eg, "it is all my fault") with different statements where responsibility is attributed more appropriately. Furthermore, decatastrophizing may help subjects, especially adolescents decide whether they may be overestimating the catastrophic nature of the precipitating event, and by allowing them to scale the event severity they learn to evaluate situations along a continuum rather than seeing them in black and white. iv. Affect Regulation techniques are often used with suicidal adolescents to teach them how to recognize stimuli that provoke negative emotions and how to mitigate the resulting emotional arousal through self-talk and relaxation.

Online Mindfulness-Based Cognitive Behavioral Therapy Intervention for Youth With Major Depressive Disorders: Randomized Controlled Trial

BACKGROUND

Approximately 70% of mental health disorders appear prior to 25 years of age and can become chronic when ineffectively treated. Individuals between 18 and 25 years old are significantly more likely to experience mental health disorders, substance dependencies, and suicidality. Treatment progress, capitalizing on the tendencies of youth to communicate online, can strategically address depressive disorders.

OBJECTIVE

We performed a randomized controlled trial (RCT) that compared online mindfulness-based cognitive behavioral therapy (CBT-M) combined with standard psychiatric care to standard psychiatric care alone in youth (18-30 years old) diagnosed with major depressive disorder.

METHODS

Forty-five participants were randomly assigned to CBT-M and standard care (n=22) or to standard psychiatric care alone (n=23). All participants were provided standard psychiatric care (ie, 1 session per month), while participants in the experimental group received an additional intervention consisting of the CBT-M online software program. Interaction with online workbooks was combined with navigation coaching delivered by phone and secure text messaging.

RESULTS

In a two-level linear mixed-effects model intention-to-treat analysis, significant between-group differences were found for the Beck Depression Inventory-II score (difference -8.54, P=.01), Quick Inventory of Depressive Symptoms score (difference -4.94, P=.001), Beck Anxiety Inventory score (difference -11.29, P<.001), and Brief Pain Inventory score (difference -1.99, P=.03), while marginal differences were found for the Five Facet Mindfulness Questionnaire-Nonjudging subscale (difference -2.68, P=.05).

CONCLUSIONS

These results confirm that youth depression can be effectively treated with online CBT-M that can be delivered with less geographic restriction.

A Mindfulness-Based Intervention for Student Depression, Anxiety, and Stress: Randomized Controlled Trial

BACKGROUND

University students are experiencing higher levels of distress and mental health disorders than before. In addressing mental health needs, web-based interventions have shown increasing promise in overcoming geographic distances and high student-to-counselor ratios, leading to the potential for wider implementation. The Mindfulness Virtual Community (MVC) program, a web-based program, guided by mindfulness and cognitive behavioral therapy principles, is among efforts aimed at effectively and efficiently reducing symptoms of depression, anxiety, and perceived stress in students.

OBJECTIVE

This study's aim was to evaluate the efficacy of an 8-week MVC program in reducing depression, anxiety, and perceived stress (primary outcomes), and improving mindfulness (secondary outcome) in undergraduate students at a large Canadian university. Guided by two prior randomized controlled trials (RCTs) that each demonstrated efficacy when conducted during regular university operations, this study coincided with a university-wide labor strike. Nonetheless, the students' response to an online mental health program on a disrupted campus can provide useful information for anticipating the impact of other disruptions, including those related to the COVID-19 pandemic as well as future disruptions.

METHODS

In this parallel-arm RCT, 154 students were randomly allocated to an 8-week MVC intervention (n=76) or a wait-list control (WLC) condition (n=78). The MVC intervention included the following: (1) educational and mindfulness video modules, (2) anonymous peer-to-peer discussions, and (3) anonymous, group-based, professionally guided, 20-minute videoconferences. Study outcomes were evaluated at baseline and at 8-week follow-up using the following: Patient Health Questionnaire-9 (PHQ-9), the Beck Anxiety Inventory (BAI), the Perceived Stress Scale (PSS), and the Five Facets Mindfulness Questionnaire Short Form (FFMQ-SF). Generalized estimation equations with an AR (1) covariance structure were used to evaluate the impact of the intervention, with outcome evaluations performed on both an intention-to-treat (ITT) and per-protocol (PP) basis.

RESULTS

Participants (n=154) included 35 males and 117 females with a mean age of 23.1 years. There were no statistically significant differences at baseline between the MVC and WLC groups on demographics and psychological characteristics, indicating similar demographic and psychological characteristics across the two groups. Results under both ITT and PP approaches indicated that there were no statistically significant between-group differences in PHQ-9 (ITT: β=-0.44, P=.64; PP: β=-0.62, P=.053), BAI (ITT: β=-2.06, P=.31; PP: β=-2.32, P=.27), and FFMQ-SF (ITT: β=1.33, P=.43; PP: β=1.44, P=.41) compared to WLC. There was a significant difference for the PSS (ITT: β=-2.31, P=.03; PP: β=-2.38, P=.03).

CONCLUSIONS

During a university labor strike, the MVC program led to statistically significant reductions in PSS compared to the WLC group, but there were no other significant between-group differences. Comparisons with previous cycles of intervention testing, undertaken during nondisrupted university operations, when efficacy was demonstrated, are discussed.

Effectiveness of an 8-Week Web-Based Mindfulness Virtual Community Intervention for University Students on Symptoms of Stress, Anxiety, and Depression: Randomized Controlled Trial

BACKGROUND

A student mental health crisis is increasingly acknowledged and will only intensify with the COVID-19 crisis. Given accessibility of methods with demonstrated efficacy in reducing depression and anxiety (eg, mindfulness meditation and cognitive behavioral therapy [CBT]) and limitations imposed by geographic obstructions and localized expertise, web-based alternatives have become vehicles for scaled-up delivery of benefits at modest cost. Mindfulness Virtual Community (MVC), a web-based program informed by CBT constructs and featuring online videos, discussion forums, and videoconferencing, was developed to target depression, anxiety, and experiences of excess stress among university students.

OBJECTIVE

The aim of this study was to assess the effectiveness of an 8-week web-based mindfulness and CBT program in reducing symptoms of depression, anxiety, and stress (primary outcomes) and increasing mindfulness (secondary outcome) within a randomized controlled trial (RCT) with undergraduate students at a large Canadian university.

METHODS

An RCT was designed to assess undergraduate students (n=160) who were randomly allocated to a web-based guided mindfulness-CBT condition (n=80) or to a waitlist control (WLC) condition (n=80). The 8-week intervention consisted of a web-based platform comprising (1) 12 video-based modules with psychoeducation on students' preidentified life challenges and applied mindfulness practice; (2) anonymous peer-to-peer discussion forums; and (3) anonymous, group-based, professionally guided 20-minute live videoconferences. The outcomes (depression, anxiety, stress, and mindfulness) were measured via an online survey at baseline and at 8 weeks postintervention using the Patient Health Questionnaire-9 (PHQ9), the Beck Anxiety Inventory (BAI), the Perceived Stress Scale (PSS), and the Five Facets Mindfulness Questionnaire Short Form (FFMQ-SF). Analyses employed generalized estimation equation methods with AR(1) covariance structures and were adjusted for possible covariates (gender, age, country of birth, ethnicity, English as first language, paid work, unpaid work, relationship status, physical exercise, self-rated health, and access to private mental health counseling).

RESULTS

Of the 159 students who provided T1 data, 32 were males and 125 were females with a mean age of 22.55 years. Participants in the MVC (n=79) and WLC (n=80) groups were similar in sociodemographic characteristics at T1 with the exception of gender and weekly hours of unpaid volunteer work. At postintervention follow-up, according to the adjusted comparisons, there were statistically significant between-group reductions in depression scores (β=-2.21, P=.01) and anxiety scores (β=-4.82, P=.006), and a significant increase in mindfulness scores (β=4.84, P=.02) compared with the WLC group. There were no statistically significant differences in perceived stress for MVC (β=.64, P=.48) compared with WLC.

CONCLUSIONS

With the MVC intervention, there were significantly reduced depression and anxiety symptoms but no significant effect on perceived stress. Online mindfulness interventions can be effective in addressing common mental health conditions among postsecondary populations on a large scale, simultaneously reducing the current burden on traditional counseling services.

An exploratory proton MRS examination of gamma-aminobutyric acid, glutamate, and glutamine and their relationship to affective aspects of chronic pain

Veterans experience chronic pain more frequently than civilians. Identification of neurobiological mechanisms underlying the pathophysiology of chronic pain in a veteran population may aid in the development of novel treatment targets. In this pilot proof-of-concept study, veterans with chronic pain (N = 61) and no chronic pain (N = 19) completed clinical interviews, self-report questionnaires inquiring about pain history, interference of pain with daily life, and pain catastrophizing, as well as measures of depressive and anxious symptoms. Veterans also underwent single-voxel proton (¹H) magnetic resonance spectroscopy (MRS) at 3 T in the anterior cingulate cortex (ACC) using a two-dimensional (2D) J-resolved point spectroscopy sequence. We found no group difference in neurometabolites between veterans with and without chronic pain; however, pain intensity, negative thinking about pain, and description of pain in affective terms were associated with lower GABA/Cre in the ACC. In addition, the Glu/GABA ratio in the ACC was positively associated with anxiety and depressive symptoms in veterans with chronic pain. Reductions in GABA in the ACC may contribute to increased pain intensity and greater pain catastrophizing in veterans with chronic pain. Furthermore, a disturbance in the excitatory-inhibitory balance may contribute to the anxious and depressive symptoms related to chronic pain. Given the pilot nature of the study, these findings must be considered preliminary.

An Online Mindfulness-Based Cognitive Behavioral Therapy Intervention for Youth Diagnosed With Major Depressive Disorders: Protocol for a Randomized Controlled Trial

Background

About 70% of all mental health disorders appear before the age of 25 years. When untreated, these disorders can become long-standing and impair multiple life domains. When compared with all Canadian youth (of different ages), individuals aged between 15 and 25 years are significantly more likely to experience mental health disorders, substance dependencies, and risks for suicidal ideation and death by suicide. Progress in the treatment of youth, capitalizing on their online responsivity, can strategically address depressive disorders.

Objective

We will conduct a randomized controlled trial to compare online mindfulness-oriented cognitive behavioral therapy (CBT-M) combined with standard psychiatric care versus psychiatric care alone in youth diagnosed with major depressive disorder. We will enroll 168 subjects in the age range of 18 to 30 years; 50% of subjects will be from First Nations (FN) backgrounds, whereas the other 50% will be from all other ethnic backgrounds. There will be equal stratification into 2 intervention groups (INT¹ and INT²) and 2 wait-list control groups (CTL¹ and CTL²) with 42 subjects per group, resulting in an equal number of INT¹ and CTL¹ of FN background and INT² and CTL² of non-FN background.

Methods

The inclusion criteria are: (1) age 18 to 30 years, FN background or other ethnicity; (2) Beck Depression Inventory (BDI)-II of at least mild severity (BDI-II score ≥14) and no upper limit; (3) Mini-International Neuropsychiatric Interview (MINI)–confirmed psychiatric diagnosis of major depressive disorder; and (4) fluent in English. All patients are diagnosed by a Centre for Addiction and Mental Health psychiatrist, with diagnoses confirmed using the MINI interview. The exclusion criteria are: (1) individuals receiving weekly structured psychotherapy; (2) individuals who meet the Diagnostic and Statistical Manual of Mental Disorders criteria for severe alcohol/substance use disorder in the past 3 months, or who demonstrate clinically significant suicidal ideation defined as imminent intent, or who have attempted suicide in the past 6 months; and (3) individuals with comorbid diagnoses of borderline personality, schizophrenia, bipolar disorder, and/or obsessive compulsive disorder. All subjects are provided standard psychiatric care defined as 1 monthly session that focuses on appropriate medication, with session durations of 15 to 30 min. Experimental subjects receive an additional intervention consisting of the CBT-M online software program (in collaboration with Nex J Health, Inc). Exposure to and interaction with the online workbooks are combined with navigation-coaching delivered by phone and secure text message interactions.

Results

The outcomes selected, combined with measurement blinding, are key features in assessing whether significant benefits regarding depression and anxiety symptoms occur.

Conclusions

If results confirm the hypothesis that youth can be effectively treated with online CBT-M, effective services may be widely delivered with less geographic restriction.

Optimal trajectories of brain state transitions

The complexity of neural dynamics stems in part from the complexity of the underlying anatomy. Yet how white matter structure constrains how the brain transitions from one cognitive state to another remains unknown. Here we address this question by drawing on recent advances in network control theory to model the underlying mechanisms of brain state transitions as elicited by the collective control of region sets. We find that previously identified attention and executive control systems are poised to affect a broad array of state transitions that cannot easily be classified by traditional engineering-based notions of control. This theoretical versatility comes with a vulnerability to injury. In patients with mild traumatic brain injury, we observe a loss of specificity in putative control processes, suggesting greater susceptibility to neurophysiological noise. These results offer fundamental insights into the mechanisms driving brain state transitions in healthy cognition and their alteration following injury.

Characterizing and Modulating Brain Circuitry through Transcranial Magnetic Stimulation Combined with Electroencephalography

The concurrent combination of transcranial magnetic stimulation (TMS) with electroencephalography (TMS-EEG) is a powerful technology for characterizing and modulating brain networks across developmental, behavioral, and disease states. Given the global initiatives in mapping the human brain, recognition of the utility of this technique is growing across neuroscience disciplines. Importantly, TMS-EEG offers translational biomarkers that can be applied in health and disease, across the lifespan, and in humans and animals, bridging the gap between animal models and human studies. However, to utilize the full potential of TMS-EEG methodology, standardization of TMS-EEG study protocols is needed. In this article, we review the principles of TMS-EEG methodology, factors impacting TMS-EEG outcome measures, and the techniques for preventing and correcting artifacts in TMS-EEG data. To promote the standardization of this technique, we provide comprehensive guides for designing TMS-EEG studies and conducting TMS-EEG experiments. We conclude by reviewing the application of TMS-EEG in basic, cognitive and clinical neurosciences, and evaluate the potential of this emerging technology in brain research.

Topiramate for cocaine dependence: a systematic review and meta-analysis of randomized controlled trials

AIMS

To assess the efficacy of topiramate in treating cocaine use disorder (i.e. retention, efficacy, safety and craving reduction) through a systematic review and meta-analysis.

METHODS

We searched six scientific databases from inception to 23 December 2014 with no date limits. Data were reviewed, extracted and analysed systematically. Studies were included if they were peer-reviewed randomized control trials with participants meeting diagnostic criteria for cocaine dependence or cocaine use disorder, with the treatment arm involving topiramate with or without psychosocial intervention, and the control arm involving no intervention or psychosocial intervention with or without placebo. A random-effects meta-analytical model was computed.

RESULTS

Five studies met inclusion criteria (n = 518). Topiramate was compared with placebo (four studies) and no medication (one study). In a meta-analysis, we observed no significant differences between topiramate and placebo in improving treatment retention risk ratio (RR) = 0.85; 95% confidence interval (CI) = 0.60-1.22, P = 0.38. However, compared with a placebo, use of topiramate was associated with increased continuous abstinence in two of five studies (RR = 2.43; 95% CI = 1.31-4.53, P = 0.005). No differences were observed in frequency of adverse effects reported between topiramate and placebo (RR = 1.06; 95% CI = 0.91-1.23, P = 0.48). Topiramate was associated significantly (P < 0.05) with a reduction in craving in only one of five studies.

CONCLUSIONS

Evidence does not currently support the use of topiramate to improve treatment retention for cocaine use disorder, although it may extend cocaine abstinence with a similar risk of adverse events compared with placebo.

Feasibility, Acceptability, and Preliminary Effects of the COPE Online Cognitive-Behavioral Skill-Building Program on Mental Health Outcomes and Academic Performance in Freshmen College Students: A Randomized Controlled Pilot Study

PROBLEM

Despite the increasing prevalence of mental health disorders in university students, few receive needed evidence-based treatment.

OBJECTIVE

The purpose of this study was to assess the feasibility and preliminary effects of a seven-session online cognitive-behavioral skill-building intervention (i.e., COPE, Creating Opportunities for Personal Empowerment) versus a comparison group on their anxiety, depressive symptoms, and grade performance.

METHODS

A randomized controlled pilot study was conducted from September 2012 to May 2013 with 121 college freshmen enrolled in a required one credit survey course.

FINDINGS

Although there were no significant differences in anxiety and depressive symptoms between the groups, only COPE students with an elevated level of anxiety at baseline had a significant decline in symptoms. Grade point average was higher in COPE versus comparison students. Evaluations indicated that COPE was a positive experience for students.

CONCLUSIONS

COPE is a promising brief intervention that can be integrated effectively into a required freshman course.

Evidence for inhibitory deficits in the prefrontal cortex in schizophrenia

Abnormal gamma-aminobutyric acid inhibitory neurotransmission is a key pathophysiological mechanism underlying schizophrenia. Transcranial magnetic stimulation can be combined with electroencephalography to index long-interval cortical inhibition, a measure of GABAergic receptor-mediated inhibitory neurotransmission from the frontal and motor cortex. In previous studies we have reported that schizophrenia is associated with inhibitory deficits in the dorsolateral prefrontal cortex compared to healthy subjects and patients with bipolar disorder. The main objective of the current study was to replicate and extend these initial findings by evaluating long-interval cortical inhibition from the dorsolateral prefrontal cortex in patients with schizophrenia compared to patients with obsessive-compulsive disorder. A total of 111 participants were assessed: 38 patients with schizophrenia (average age: 35.71 years, 25 males, 13 females), 27 patients with obsessive-compulsive disorder (average age: 36.15 years, 11 males, 16 females) and 46 healthy subjects (average age: 33.63 years, 23 females, 23 males). Long-interval cortical inhibition was measured from the dorsolateral prefrontal cortex and motor cortex through combined transcranial magnetic stimulation and electroencephalography. In the dorsolateral prefrontal cortex, long-interval cortical inhibition was significantly reduced in patients with schizophrenia compared to healthy subjects (P = 0.004) and not significantly different between patients with obsessive-compulsive disorder and healthy subjects (P = 0.5445). Long-interval cortical inhibition deficits in the dorsolateral prefrontal cortex were also significantly greater in patients with schizophrenia compared to patients with obsessive-compulsive disorder (P = 0.0465). There were no significant differences in long-interval cortical inhibition across all three groups in the motor cortex. These results demonstrate that long-interval cortical inhibition deficits in the dorsolateral prefrontal cortex are specific to patients with schizophrenia and are not a generalized deficit that is shared by disorders of severe psychopathology.

The acute effects of exercise on cortical excitation and psychosocial outcomes in men treated for prostate cancer: a randomized controlled trial

Purpose: Regular exercise improves psychological well-being in men treated for prostate cancer (PCa). For this population and among cancer survivors in general, the effect of a single bout of exercise on self-report or objective measures of psychological well-being has not been examined. We examined the acute effect of a single bout of exercise on the cortical silent period (CSP) and on self-reported mood in men that have received treatment for PCa.

Methods: Thirty-six PCa survivors were randomly assigned to 60 min of low to moderate intensity exercise or to a control condition. Outcomes were assessed immediately before and after either the exercise or the control condition.

Results: No significant between-group differences were observed in CSP or mood were observed following the exercise session or control conditions. Participants with higher scores of trait anxiety had significantly shorter CSP at baseline, as well as those receiving androgen deprivation therapy. Age and baseline CSP had a low-moderate, but significant negative correlation. Changes in CSP following the exercise condition were strongly negatively correlated with changes in self-reported vigor.

Conclusion: While we did not observe any acute effect of exercise on the CSP in this population, the associations between CSP and trait anxiety, age, and vigor are novel findings requiring further examination.

Implications for Cancer Survivors: Exercise did not acutely affect our participants in measures of psychological well-being. Additional mechanisms to explain the chronic psychosocial benefits of exercise previously observed in men with PCa require further exploration.

Can Psychological Interventions Reduce Perfectionism? A Systematic Review and Meta-analysis

Background:Perfectionism is implicated in a range of psychiatric disorders, impedes treatment and is associated with poorer treatment outcomes.Aims:The aim of this systematic review and meta-analysis was to summarize the existing evidence for psychological interventions targeting perfectionism in individuals with psychiatric disorders associated with perfectionism and/or elevated perfectionism.Method: Eight studies were identified and were analysed in meta-analyses. Meta-analyses were carried out for the Personal Standards and Concern over Mistakes subscales of the Frost Multi-Dimensional Perfectionism Scale (FMPS) and the Self Orientated Perfectionism and Socially Prescribed Perfectionism subscales of the Hewitt and Flett MPS (HMPS) in order to investigate change between pre and postintervention.Results:Large pooled effect sizes were found for the Personal Standards and Concern over Mistakes subscales of the FMPS and the Self Orientated Perfectionism subscale of the HMPS, whilst a medium sized effect was found for change in Socially Prescribed Perfectionism. Medium pooled effect sizes were also found for symptoms of anxiety and depression.Conclusions:There is some support that it is possible to significantly reduce perfectionism in individuals with clinical disorders associated with perfectionism and/or clinical levels of perfectionism. There is also some evidence that such interventions are associated with decreases in anxiety, depression, eating disorder and obsessive compulsive symptoms. Further research is needed in order to investigate the optimal dosage and format of such interventions as well as into specific disorders where there is a lack of evidence for their effectiveness.

The EEG correlates of the TMS-induced EMG silent period in humans

Application of magnetic or electrical stimulation to the motor cortex can result in a period of electromyography (EMG) silence in a tonically active peripheral muscle. This period of EMG silence is referred to as the silent period (SP). The duration of SP shows intersubject variability and reflects the integrity of cortical and corticospinal pathways. A non-invasive technique for assessing the duration of SP is the combination of Transcranial Magnetic Stimulation (TMS) with EMG. Utilizing TMS-EMG, several studies have reported on the shortening or lengthening of SP in neuropsychiatric disorders such as schizophrenia, bipolar disorder, depression, obsessive compulsive disorder, epilepsy, Parkinson's disease, and stroke. However, cortical, corticospinal and peripheral components are difficult to disentangle from EMG alone. Here, we use the multimodal neuroimaging technique of TMS-EMG combined with concurrent electroencephalography (EEG) recording to further examine the cortical origin of SP and the cortical oscillatory activity that underlies SP genesis. We demonstrate that the duration of SP is related to the temporal characteristics of the cortical reactivity and the power of delta to alpha oscillations in both local and remote areas ipsilateral and contralateral to the stimulation site, and beta oscillations locally. We illustrate that, compared to EMG, the EEG indices of the SP provide additional information about the brain dynamics and propose that the EEG measures of SP may be used in future clinical and research investigations to more precisely delineate the mechanisms underlying inhibitory impairments.

Evaluating a Web-based cognitive-behavioral therapy for maladaptive perfectionism in university students

OBJECTIVE

This study assessed a Web-based cognitive-behavioral therapy (CBT) for maladaptive perfectionism, investigating perfectionism, anxiety, depression, negative automatic thoughts, and perceived stress.

PARTICIPANTS

Participants were undergraduate students defined as maladaptive perfectionists through a screening questionnaire at an urban university. The data were collected from July 2009 to August 2010.

METHODS

Forty-seven maladaptive perfectionists were randomly assigned to a 12-week CBT or a wait-list control group and assessed via questionnaires at pre- and postintervention. Statistical procedures included t tests, Pearson correlations, and analysis of covariance.

RESULTS

At the postintervention measure, the CBT group demonstrated significant decreases in anxiety sensitivity and negative automatic thoughts compared to the control group. Within the CBT group, changes in perfectionism scores were significantly correlated with positive changes in depression, anxiety, stress, and automatic thoughts.

CONCLUSIONS

The treatment group improved on psychological outcomes, demonstrating the effectiveness of a Web-based CBT for perfectionism in a university setting.
