ABSTRACT

BACKGROUND: The cut points of psychological tools to diagnose clinical conditions are not universal and depend on the region and prevalence of the disorder. Thus, we aimed to identify the cutoff points of the Persian original version of the personality inventory for DSM-5 (PID-5; 220 items) that would optimally distinguish nonclinical from clinical groups. METHODS: Both nonclinical (N = 634, 73% female, 34.0 ± 10.8 years) and clinical (N = 454, 29% female, 29.5 ± 7.4 years) samples from the West of Iran participated in the study. Data were analyzed using receiver operating characteristic (ROC) and Youden's index was used to determine the cutoff scores across the PID-5 domains and facets. The means and standard deviations of both the clinical male and female were compared with the nonclinical group using Cohen's d and independent t-tests. RESULTS: All the PID-5 algorithms and facets significantly distinguished clinical from nonclinical samples with some unique findings for male and female samples. The mean score of all the PID-5 algorithms and facets in the clinical male and female samples were respectively 1.0-2.0 SD and 0.5-1.0 SD above the mean for the nonclinical counterparts. A score higher than 1.5 on ranging from 0 to 3 in each domain or facet indicated clinical status. CONCLUSION: Raw cutting scores throughout the PID-5 algorithms can be well used to diagnose any pathology of personality and the severity of the disorder in clinical patients. The cut scores provide a useful tool for the clinical use of the original version of PID-5 in Iran.

ABSTRACT

BACKGROUND: If somatization is an independent personality trait, it is not clear whether it is specific to the temperament or maladaptive spectrum of personality. We aimed at the head-to-head comparison of temperament and maladaptive systems and spectra of personality to predict both somatization and somatic symptom and related disorders (SSRD). METHODS: The samples included 257 cases with SSRD (70.8% female) and 1007 non-SSRD (64.3% female) from Western Iran. The Personality Inventory for DSM-5 (PID-5), Personality Diagnostic Questionnaire-4 (PDQ-4), Temperament and Character Inventory (TCI), Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A), Affective and Emotional Composite Temperament Scale (AFECTS), and Positive Affect and Negative Affect Model (PANAS) was used to data collection. A somatization factor plus temperament and maladaptive spectra of personality were extracted using exploratory factor analysis. Several hierarchical linear and logistic regressions were used to test the predictive systems and spectra. RESULTS: All personality systems jointly predict both somatization and SSRD with a slightly higher contribution for temperament systems. When the temperament and maladaptive spectra were compared, both spectra above each other significantly predicted both somatization (R2 = .407 versus .263) and SSRD (R2 = .280 versus .211). The temperament spectrum explained more variance beyond the maladaptive spectrum when predicting both the somatization factor (change in R2 = .156 versus .012) and SSRD (change in R2 = .079 versus .010). CONCLUSION: All temperament and maladaptive frameworks of personality are complementary to predicting both somatization and SSRD. However, the somatization is more related to the temperament than the maladaptive spectrum of personality.

ABSTRACT

BACKGROUND: The Personality Inventory for DSM-5 (PID-5) and Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) are tools designed for personality dispositions for mental health symptoms. The present study was conducted to compare these models in terms of their relative sensitivity to the symptoms of personality disorders (PDs) and non-personality disorders (NPDs). METHODS: Subjects in this cross-sectional study were 1232 (805 female; 63.5%) community samples in western Iran. Data were collected using the PID-5, the TEMPS-A, the Symptom Checklist-90 (SCL-90-R), and the Personality Diagnostic Questionnaire (PDQ-4). Correlations and Regression models were used to examine associations between traits and symptoms. RESULTS: Maladaptive traits assessed by the PID-5 were more strongly associated with PD symptoms, whereas affective temperaments measured by the TEMPS-A were more strongly associated with NPD symptoms. CONCLUSION: The present findings highlighted the practical utility of both the PID-5 and TEMPS-A indicating risk for psychopathology, but also suggest a distinction between PDs and NPDs in terms of underlying personality dispositions.

ABSTRACT

BACKGROUND: Patients with schizophrenia can generally manifest a broad variety of primary negative symptoms. The current study aimed to assess the efficacy and tolerability of resveratrol add-on therapy in the treatment of negative symptoms in patients with stable schizophrenia. METHODS: In a randomized, double-blind, and placebo-controlled setting, schizophrenia patients were assigned to receive either 200 mg/d resveratrol or matched placebo in addition to a stable dose of risperidone for 8 weeks. Patients were assessed using the positive and negative syndrome scale, the extrapyramidal symptom rating scale, and Hamilton Depression Rating Scale over the trial period. The primary outcome was considered as the change in positive and negative subscale score from baseline to week 8 between the treatment arms. RESULTS: A total 52 patients completed the trial (26 in each arm). Baseline characteristics of both groups were statistically similar (P > .05). Despite the statistically similar behavior of positive symptoms between the groups across time (Greenhouse-Geisser corrected: F = 1.76, df = 1.88, P = .180), the resveratrol group demonstrated greater improvement in negative, general psychopathology, and total scores (Greenhouse-Geisser corrected: F = 12.25, df = 2.04, P < .001; F = 5.42, df = 1.56, P = .011; F = 7.64, df = 1.48, P = .003). HDRS scores and its changes, ESRS score, and frequency of other complications were not significantly different between resveratrol and placebo groups. CONCLUSION: Adding resveratrol to risperidone can exhibit remarkable efficacy and safety in terms of management of schizophrenia-related negative symptoms.

ABSTRACT

WHAT IS KNOWN AND OBJECTIVE: The underlying pathophysiology of autism spectrum disorder (ASD) has been linked to immune dysregulation, oxidative stress and excitation-inhibition imbalance. Among associated symptoms of ASD, management of irritability has gained considerable attention as it complicates adjustment of ASD patients and thus necessitates its pharmacological treatment. Resveratrol is a plant phytoalexin, which has been demonstrated to have neuroprotective effects through its anti-inflammatory and antioxidant properties. This double-blind, placebo-controlled randomized trial was designed to assess the potential therapeutic effects of resveratrol plus risperidone on irritability of ASD patients. METHODS: Sixty-two patients were assigned randomly into two groups of resveratrol and placebo. Both groups were treated with risperidone twice daily starting at a dose of 0.5 mg with a dose increase of 0.5 mg per week (for the first 3 weeks). Resveratrol dosage was 250 mg twice per day from the beginning of the study. Using the Aberrant Behavior Checklist-Community (ABC-C), patients were assessed for ASD-related behavioural symptoms at baseline, week 5 and week 10. The frequency of adverse events was recorded using a checklist containing 25 possible side effects, including general, gastrointestinal, neurological and cardiovascular complications. RESULTS AND DISCUSSION: Improvements in primary outcome measure (irritability) and three secondary outcome measures (lethargy/social withdrawal, stereotypic behaviour and inappropriate speech subscales) in the resveratrol group were statistically similar to those in the placebo group. The repeated measures analysis showed no time × treatment interaction on these subscale scores. In contrast, patients in the resveratrol group showed greater decline in hyperactivity/non-compliance score as a secondary outcome measure (mean difference [CI = 95%] = 4.51 [0.10-8.92], t = 2.04; P = .04), and repeated measures analysis showed significant effect for time × treatment effect on this subscale score (F = 3.81; df = 1.30; P = .043). There was no significant difference in number and severity of adverse events between the two groups. WHAT IS NEW AND CONCLUSION: This clinical trial demonstrated no significant effect for adjunctive treatment with resveratrol on irritability of patients with ASD. However, it provided preliminary evidence indicating that resveratrol could improve hyperactivity/non-compliance of ASD patients.

ABSTRACT

AIM: The role of the glutamatergic system in the pathogenesis of obsessive-compulsive disorder (OCD) has been shown by numerous studies. The aim of the present randomized, double-blind, placebo-controlled, 12-week trial was to assess the efficacy and tolerability of amantadine as an adjuvant to fluvoxamine in the treatment of patients with moderate to severe OCD. METHODS: One hundred patients diagnosed with moderate to severe OCD were randomized into two parallel groups to receive fluvoxamine (100 mg twice a day) plus placebo or fluvoxamine (100 mg twice a day) plus amantadine (100 mg daily) for 12 weeks. All patients received 100 mg/day fluvoxamine for 28 days followed by 200 mg/day for the rest of the trial, regardless of their treatment groups. Patients were evaluated for response to treatment using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) at baseline and at Weeks 4, 10, and 12. The main outcome measure was to assess the efficacy of amantadine in improving the OCD symptoms. RESULTS: Repeated-measure analysis of variance showed a significant effect for Time × Treatment interaction (Greenhouse-Geisser corrected: F = 3.84, d.f. = 1.50, P = 0.03) in the Y-BOCS total score and a significant effect for Time × Treatment interaction (Greenhouse-Geisser corrected: F = 5.67, d.f. = 1.48, P < 0.01) in the Y-BOCS Obsession subscale score between the two groups. CONCLUSION: The results of this study suggest that amantadine may be effective as an augmentative agent in the treatment of moderate-to-severe OCD.

ABSTRACT

OBJECTIVE: We aimed to evaluate the efficacy and tolerability of citicoline add-on therapy in treatment of negative symptoms in patients with stable schizophrenia. METHODS: In a double-blind and placebo-controlled study, patients with stable schizophrenia (DSM-5) were randomized to receive either 2,500 mg/day citicoline or placebo in addition to risperidone for 8 weeks. The patients were assessed using the positive and negative syndrome scale (PANSS), the extrapyramidal symptom rating scale (ESRS), and Hamilton depression rating scale (HDRS). The primary outcome was the difference in PANSS negative subscale score reduction from baseline to week 8 between the citicoline and the placebo groups. RESULTS: Sixty-six individuals (out of 73 enrolled) completed the trial. The citicoline group demonstrated significantly greater improvement in negative scores, F(1.840, 118.360) = 8.383, p = .001, as well as general psychopathology, F(1.219, 78.012) = 6.636, p = .008; change in general psychopathology did not remain significant after adjustment, and total PANSS scores, F(1.633, 104.487) = 15.400, p < .001, compared with the placebo. HDRS scores and its changes, ESRS score, and frequency of other side effects were not significantly different between the two groups. CONCLUSIONS: Citicoline add-on therapy to risperidone can effectively improve the primary negative symptoms of patients with schizophrenia.

ABSTRACT

BACKGROUND: Dysregulation of glutamate is implicated in the pathogenesis of obsessive-compulsive disorder (OCD). Consistently, glutamate-modulating agents, such as riluzole and memantine have been used in OCD treatment. Previous research has identified some neuroprotective role for L-carnosine potentially via its modulatory effect on glutamate. Here, we assessed the efficacy of L-carnosine as adjuvant to fluvoxamine in OCD treatment. METHODS: Forty-four patients diagnosed with moderate to severe OCD were recruited in a randomized double-blind trial. Patients received either L-carnosine or placebo as adjuvant to fluvoxamine for 10 weeks. The Yale- Brown Obsessive Compulsive Scale (Y-BOCS) was used for assessing the severity of symptoms at baseline and at weeks 4, 8, and 10. RESULTS: General linear model repeated measure showed significant effects for Time × Treatment interaction on total Y-BOCS [F (2.10, 88.42) = 8.66, p < 0.001], obsession [F (1.88, 79.34) = 4.96, p = 0.01] and compulsion [F (1.88, 79.11) = 4.57, p = 0.01]. At week 10, the change from baseline in Y-BOCS scores was 8.86 ± 2.89 (mean ± SD) in the L-carnosine group compared to 5.86 ± 2.88 in the placebo group. CONCLUSION: L-carnosine results in significant reduction of obsessive-compulsive symptoms when used as an adjuvant to fluvoxamine.

ABSTRACT

OBJECTIVE: To evaluate the efficacy and safety of cilostazol, a selective inhibitor of phosphodiesterase III, as an adjunctive to risperidone in alleviating the negative symptoms of schizophrenia. METHODS: Eighty-four in-patients with diagnosis of chronic schizophrenia participated in a randomized, placebo-controlled trial and underwent 8 weeks of treatment with either cilostazol (50 mg twice a day) or placebo as an adjuvant to risperidone. Participants were assessed using the positive and negative syndrome scale (PANSS) at baseline and at weeks 2, 4, 6, and 8. The primary outcome measure of the trial was to evaluate the efficacy of cilostazol compared to placebo in improving the PANSS negative subscale score. RESULT: General linear model repeated measures demonstrated significant effect for time × treatment interaction on negative subscale scores (p < .001) and PANSS total (p = .006) but did not demonstrate significant effect on the PANSS positive (p = .37) and general (p = .06) subscales. Frequency of adverse events was not significantly different between the 2 treatment groups. No serious adverse event was observed. CONCLUSION: An 8-week course of treatment with cilostazol as an adjunct to risperidone showed a favorable safety and efficacy profile in patients with schizophrenia.

ABSTRACT

OBJECTIVES: Recent research has focused on the inflammatory cascade as a key culprit in the etiology of bipolar disorder. We hypothesized that celecoxib, via its anti-inflammatory properties, may have a therapeutic role in mood disorder. METHODS: Forty-six inpatients with the diagnosis of acute bipolar mania without psychotic features participated in a parallel, randomized, double-blind, placebo-controlled trial, and underwent six weeks of treatment with either celecoxib (400 mg daily) or placebo as an adjunctive treatment to sodium valproate. Patients were evaluated using the Young Mania Rating Scale (YMRS) and Hamilton Depression Rating Scale (HDRS). The primary outcome measure with respect to efficacy was the mean decrease in YMRS score from baseline to the study endpoint, which was compared between the two groups. RESULTS: A significant difference was observed in the change in YMRS scores on Day 42 compared to baseline in the two groups (p < 0.001). The changes at the endpoint compared to baseline were -29.78 ± 21.78 (mean ± standard deviation) and -21.78 ± 7.16 for the celecoxib and placebo groups, respectively. A significantly higher remission rate was observed in the celecoxib group (87.0%) than the placebo group (43.5%) at Week 6 (p = 0.005). General linear model repeated measures demonstrated a significant effect for the time × treatment interaction on the YMRS scores [F(2.27,99.98) = 6.67, p = 0.001]. CONCLUSIONS: Celecoxib is an effective adjuvant therapy in the treatment of manic episodes (without psychotic features) of bipolar mood disorder. The mood-stabilizing role of the drug might be mediated via its action on the inflammatory cascade.

ABSTRACT

Background: Psychopathology research mainly focused on the cross-sectional and longitudinal associations between personality and psychiatric disorders without considering the moment-to-moment dynamics of personality in response to environmental situations. The present study aimed to both cluster a young sample according to three mixed clinical conditions (poor sleep quality, depression, and somatization) and to predict the derived clusters by maladaptive personality traits and sex differences using a deep machine learning approach. Methods: A sample of 839 adults aged 18-40 years (64% female) from the west of Iran were clustered according to the mixed clinical conditions using the cluster analysis techniques. An Artificial Neural Network (ANN) modeling is used to predict the derived clusters by maladaptive personality traits and biological gender. A receiver operating characteristic (ROC) curve was used to identify independent variables with high sensitivity specific to the derived clusters. Results: The cluster analysis techniques suggested a fully stable and acceptable four-cluster solution for Depressed Poor Sleepers, Nonclinical Good Sleepers, Subclinical Poor Sleepers, and Clinical Poor Sleepers. The ANN model led to the identification of one hidden layer with two hidden units. The results of Area under the ROC Curve were relatively to completely acceptable, ranging from.726 to.855. Anhedonia, perceptual dysregulation, depressivity, anxiousness, and unusual beliefs are the most valuable traits with importance higher than 70%. Conclusion: The machine learning approach can be well used to predict mixed clinical conditions by maladaptive personality traits. Future research can test the complexity of normal personality traits connected to mixed clinical conditions.

ABSTRACT

Hierarchical psychopathology contributes to providing a broader picture of the links between emerging personality structures such as the DSM-5/ICD-11 trait models and clinical disorders. The present study aimed to predict the specific and general clinical symptoms by the less studied constructs of the ICD-11 model (negative affectivity, detachment, dissociality, disinhibition, and anankastia). Data from 642 young adults from Iran (63% female, 18-34 years) were collected by three mental symptom scales and the Personality Inventory for DSM-5 (PID-5), which was recently used to harmonize the constructs of the DSM-5 and ICD-11 trait models. Multiple linear regressions showed that the ICD-11 model significantly predicted both the specific clinical symptoms (ranging from R2 = 0.15 to 0.40) and the general factor of clinical symptoms extracted by exploratory factor analysis (R2 = 0.40, all p < 0.001). Negative affectivity was the strongest construct correlated with both the specific symptoms (ranging from ß = 0.36 to 0.69) and the general symptom factor (ß = 0.59, all p < 0.001). Because the ICD-11 trait model is a practical structure related to the clinical psychopathology in young adults, screening for maladaptive traits can help clinicians in case formulation for diagnosis and treatment.

ABSTRACT

Background: There is little and heterogeneous knowledge on the links between the temperamental predispositions of psychopathology and the contemporary dimensional models of psychopathology, such as the Hierarchical Taxonomy of Psychopathology (HiTOP) classification system, which can be aligned with the five-factor model (FFM) of personality. This meta-analysis seeks to expand the temperamental theoretical basis of the HiTOP model by incorporating associations of temperament traits of two temperamental theories measured, respectively, by the Temperament and Character Inventory (TCI) and the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) with (a) the FFM's personality domains and (b) HiTOP's five psychopathological spectra. Methods: A systematic search was done on Web of Science, Scopus, PubMed, ProQuest, Cochrane Database, and Google Scholar for all articles published in English from January 1990 to August 2020. Because of heterogeneity in the results of almost 70% of studies, pooled estimates of correlation coefficients were calculated using the random-effects method. Risk of bias (low-quality studies) and publication bias are reported. Results: The pooled correlations obtained from the analysis of 35 studies showed that the temperamental profile associated with each FFM domain and HiTOP spectra is distinct. Specifically, TCI-harm avoidance (HA) and all TEMPS temperaments were more strongly related to neuroticism/internalizing, extraversion/low detachment, and conscientiousness/disinhibition. In contrast, TCI-novelty seeking was more strongly related to both disinhibited/antagonistic externalizing and thought disorder. Conclusions: A large body of research supports maladaptive variants of all FFM domains and some psychopathological spectra of HiTOP related to the abnormal-range temperaments.

ABSTRACT

The present study examined the extent to which the currently established factor structure of the Personality Inventory for DSM-5 (PID-5; Krueger et al., 2013) generalizes to a large Persian community sample, as well as relations between the resulting PID-5 factors and two temperament measures. Cross-sectional data came from 946 adults (65% female) from western Iran. With the use of exploratory structural equation modeling (ESEM) with target rotation, we found factor loadings that showed fairly similar patterns to those found in two previous meta-analytic PID-5 studies with predominantly North American and European samples (Watters & Bagby, 2018; Somma et al., 2019). Despite slight differences in each of the target rotations, there were moderate congruence coefficients (~0.85) between loadings for the five PID-5 domains, with the weakest evidence supporting the Disinhibition factor. The resulting PID-5 factors showed meaningful associations with temperament domains assessed via the Temperament and Character Inventory (TCI; Cloninger, 1994) and Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire (TEMPS-A; Akiskal et al., 2005). Overall, our findings suggest that the documented structure of personality pathology assessed by the PID-5 generalizes somewhat to this sample of Persian participants, and pathological personality traits show important overlap with temperament, although these constructs are meaningfully distinct.

ABSTRACT

We aimed to evaluate the efficacy of memantine add-on in the treatment of primary negative symptoms of patients with stable schizophrenia. In a double-blind placebo-controlled clinical trial, 40 patients with schizophrenia (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) who were stabilized on risperidone for a minimum of 8 weeks were randomized to either memantine (20 mg) or placebo in addition to risperidone, 6 mg/d, for eight weeks. Assessment was done using the Positive and Negative Syndrome Scale at baseline, week 4, and week 8. The Hamilton Depression Rating Scale and the Extrapyramidal Symptom Rating Scale at baseline and week 8 were used to assess depression and extrapyramidal symptoms, respectively. All 40 patients had at least one postbaseline measurement, and 38 patients completed the trial. Patients in the memantine group showed a significantly greater improvement on negative subscale than the placebo group at end point (P < 0.001). The same effect was observed for the total score (P < 0.001) and the general psychopathology subscale score (P = 0.002). There was no significant difference in reduction of positive symptoms score between the 2 groups (P = 0.757). Changes in the Hamilton Depression Rating Scale and the Extrapyramidal Symptom Rating Scale scores and frequency of adverse effects did not differ between the 2 groups. Our study showed that memantine is a tolerable and efficacious add-on treatment for primary negative symptoms of schizophrenia.

ABSTRACT

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a phenotypic data-driven framework for the classification of psychopathology. We tested the construct and criterion validity of the HiTOP spectra measured by the Personality Inventory for DSM-5 (PID-5) using exploratory structural equation modeling (ESEM) and hierarchical regressions both to predict somatic symptom and related disorders (SSRD) and a somatization factor. The case-control study used hierarchical logistic regressions to distinguish 257 cases with SSRD from 1007 healthy controls by both the maladaptive and the temperament factors. The extracted factors were also used in hierarchical linear regressions to predict the dimensional somatization factor. The seven temperament factors explained more variance above and beyond the five maladaptive factors when predicting SSRD (pseudo R2 = 0.169 to 0.266 versus 0.125 to 0.196; change in pseudo R2 = 0.055 to 0.087 versus 0.011 to 0.017). The temperament factors also explained more variance above and beyond the maladaptive factors when predicting the somatization factor (R2 = 0.392 versus 0.269; change in R2 = 0.146 versus 0.023). Although the HiTOP spectra measured by PID-5 are significant structures related to the categorical and dimensional measurements of somatoform, our findings highlight potential problems with both the construct and criterion validity of the HiTOP spectra.

ABSTRACT

OBJECTIVES: To investigate the effect of adding remifentanil to propofol used in the induction of anesthesia in efficacy, and to investigate the cognitive adverse effects of electroconvulsive therapy (ECT) in the treatment of patients with severe mania. METHODS: Thirty-eight patients' condition was diagnosed as manic episode by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria and were prescribed ECT by their physicians were included in a double-blind study and were randomly allocated to receive premedication with either remifentanil-atropine (study) or saline-atropine (control). Induction of anesthesia was done with propofol (1 mg/kg) and succinylcholine (0.5 mg/kg) in all patients. Assessments included seizure duration, Young Mania Rating Scale (YMRS), Mini-Mental State Examination (MMSE), and immediate cognitive adverse effects. RESULTS: Twenty-nine patients with 98 ECT sessions completed treatment. There were no differences between the 2 groups in relation to age, sex, duration of disease, weight, marital status, seizure duration, YMRS, and MMSE. However, immediate cognitive adverse effects were significantly lower in remifentanil group.

ABSTRACT

Ginkgo biloba has been reported to affect the neurotransmitter system and to have antioxidant properties that could impact the pathogenesis of Autism Spectrum Disorder. Based on these studies, we decided to assess the effectiveness of Ginkgo biloba extract (Ginko T.D., Tolidaru, Iran) as an adjunctive agent to risperidone in the treatment of autism. Forty-seven outpatients with a DSM-IV-TR diagnosis of autism ages between 4 and 12 years were assigned to this double blinded clinical trial and were randomly divided into two groups. One group received risperidone plus Ginko T.D and the other received risperidone plus placebo. The dose of risperidone was 1-3 mg/day and the dose of Ginko T.D. was 80 mg/day for patients under 30 kg and 120 mg/day for patients above 30 kg. Patients were assessed using Aberrant Behavior Checklist-Community (ABC-C) rating scale and the side effect check list every 2 weeks until the endpoint. None of the 5 subscales of ABC-C rating scale showed significant differences between the two groups. Incidents of side effects were not significantly different between the two groups. Adding Ginkgo biloba to risperidone did not affect the treatment outcome of ADs. Nevertheless, further observations are needed to confirm this result.

ABSTRACT

Recent advances in clinical practice emphasize the utility of Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders (UP) as an effective intervention for targeting core processes underlying comorbid disorders. This study aimed to evaluate changes in psychopathological risk factors associated with the construct of neuroticism (i.e., negative affect, anxiety sensitivity, experiential avoidance, intolerance of uncertainty) within the UP to adults already on an optimal and stable dose of SSRIs. In a randomized controlled trial, a total of 39 adults (Mage = 27.51 [±8.43]; 56.4% female) on SSRIs with a diagnosis of comorbid anxiety and depressive disorder were randomly assigned to either UP + SSRI (n = 18) or continued SSRI-only (n = 21). Neuroticism dimensions were assessed at baseline, posttreatment, and 1-month follow-up. UP + SSRI condition demonstrated medium to large effect sizes for changes over time on facets of neuroticism including negative affect (Cohen's d = 1.12, 95% confidence interval [CI; 0.44, 1.80]), anxiety sensitivity (Cohen's d = 1.21, 95% CI [0.53, 1.90]), experiential avoidance (Cohen's d = 0.74, 95% CI [0.09, 1.04]), and intolerance of uncertainty (Cohen's d = 1.66, 95% CI [0.93, 2.39]). Post hoc analyses showed reductions in variables that were maintained at follow-up. Results adds to the growing body of literature and provide cross-cultural support for the utility of UP in targeting pathological risk factors as adjuncts to SSRI. Implications for future studies and limitations are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
