ABSTRACT
Objective:To investigate the effect of intolerance of uncertainty (IU) on state worry, state anxiety, and galvanic skin response in college students with medium and low trait anxiety.Methods:The trait anxiety inventory (TAI) and the intolerance of uncertainty scale (IUS) were used to investigate 1 378 college students in Beijing. A total of 537 individuals with medium or low trait anxiety (TAI score ≤54) were selected, from which high IU individuals (IUS score ≤58) and low IU individuals (IUS score > 58) were selected and allocated to uncertain group ( n=28) and certain group ( n=28) according to gender, age, education level and IU score. The modified NPU paradigm task, the penn state worry questionnaire(PSWQ)and the brief state anxiety measurement(BSAM) were used to assess the subjects' worry and anxiety.The galvanic skin response of individuals completing the NPU paradigm task was recorded.SPSS 26.0 was used for a two factor analysis of variance (classification: high IU, low IU; group: uncertain group, certain group). Results:The results of the two factor analysis of variance showed that the interaction between individual state anxiety classification and group was not significant( F(1, 55)=0.05, P>0.05, η2=2.16). The main effect of classification was significant( F(1, 55)=24.17, P<0.05, η2=1143.01). The anxiety level of individuals with high IU was significantly lower than that of individuals with low IU( P<0.05). The group main effect was not significant( F(1, 55)=0.03, P>0.05, η2=1.45), and there was no significant difference between the uncertainty group and the certainty group in terms of worry( P>0.05). The interaction between individual state anxiety classification and group was significant ( F(1, 55)=4.38, P<0.05, η2=3.02). The simple analysis results showed that in the uncertain group, the state anxiety of individuals with high IU was significantly lower than that of individuals with low IU ( P<0.05). In the certain group, there was no significant difference in state anxiety between individuals with high and low IU ( P>0.05). The interaction between individual galvanic skin response classification and group was not significant ( F(1, 55)=0.03, P>0.05, η2=0.00). The classification main effect was not significant( F(1, 55)=0.07, P>0.05, η2=0.00), and there was no significant difference in skin electrical activity between individuals with high and low IU ( P>0.05). But the main effect of the group was significant( F(1, 55)=4.86, P<0.05, η2=0.03). The skin electrical activity of the uncertain group was higher than that of the certain group( P<0.05). Conclusion:In the college students with medium and low trait anxiety, IU is an effective predictor of individual state worry and state anxiety under uncertain conditions.
ABSTRACT
【Objective】 To explore the relationship between chronic comorbidity and the physical and mental health of relatives of elderly people during the nursing home confinement, and to analyze the mediating effects of perceived stress and intolerance of uncertainty in this context. 【Methods】 A total of 568 family members of elderly people in nine elderly institutions in Shaanxi Province were selected. The survey included the short version of the Perceived Stress Scale, Intolerance of Uncertainty Scale, and The World Health Organization-5 Well-being Index. The data were analyzed with Stata for correlation and mediation effects. 【Results】 ① The comorbidities of chronic diseases was positively correlated with the perceived stress (r=0.16, P<0.001) and intolerance of uncertainty (r=0.11, P=0.006) of the family members, but negatively correlated with the physical and mental health of the family members (r=-0.13, P=0.002). ② The mediating effect of perceived stress between chronic disease co-morbidity and physical and mental health of family members in older adults was -0.023, accounting for 18.8% of the total effect; the mediating effect of intolerance of uncertainty between chronic disease co-morbidity and physical and mental health of family members in older adults was -0.041, accounting for 33.5% of the total effect. 【Conclusion】 During closed management in a nursing facility, the physical and mental health of family members of older adults with chronic co-morbidities is poorer than that of family members of non-chronic co-morbidities. And it can lead to a decline in physical and mental health of family members through increased perceived stress and intolerance of uncertainty.
ABSTRACT
The purpose of this paper is to review the research on the influence and mechanism of intolerance of uncertainty （IU） on anxiety both at home and abroad in recent years. IU refers to the individual's disgust response due to the intolerance of perceived lack of prominent， critical or sufficient information， and it has individual tendency. IU plays an important role in the occurrence and development of anxiety， but the specific process and mechanism remain unclear. This paper reviews the influence of IU on anxiety， and clarifies its mechanism of action on the generation and development of anxiety from the perspectives of cognition， emotion and behavior， so as to provide references for preventing the development of general anxiety into anxiety disorders and developing new psychological intervention and treatment strategies.
ABSTRACT
Objective:To examine the roles of the threat to self-moderator (intolerance of uncertainty) and the motivational moderator (meaning in life) in the relationship between triggering variables (thwarted belongingness and fear of negative evaluation) and outcome variables (suicidal ideation and suicidal behavior) based on the integrated motivational-volitional model of suicidal behavior.Methods:A total of 1 325 university freshmen were investigated with the thwarted belongingness questionnaire, the brief fear of negative evaluation scale, the intolerance of uncertainty scale, the meaning in life questionnaire, the positive and negative suicide ideation inventory and the suicidal behaviors questionnaire-revised.SPSS 24.0 software was used for descriptive statistics, independent sample t-test, Pearson correlation analysis, and moderating effect analysis. AMOS 20.0 software was used for mediating effect analysis. Results:(1) Female students had more fear of negative evaluation than males ((41.89±9.96), (40.31±10.68), t=2.03, P<0.05). Students from rural areas experienced more thwarted belongingness than students from urban areas ((23.83±8.87), (22.49±9.17), t=2.51, P<0.05). (2) Thwarted belongingness, fear of negative evaluation, and intolerance of uncertainty were positively related to suicidal ideation and suicidal behavior ( r=0.24-0.59, all P<0.001), while meaning in life was negatively related to suicidal ideation and suicidal behavior ( r=-0.43, r=-0.22, both P<0.001). (3) Suicidal ideation mediated the relationship between thwarted belongingness and suicidal behavior ( β=0.34, P<0.001) and mediated the relationship between fear of negative evaluation and suicidal behavior ( β=0.11, P<0.001). (4) Compared to the students with lower levels of intolerance of uncertainty, for those who had higher levels of intolerance of uncertainty, thwarted belongingness had a stronger predictive power on suicidal ideation ( β=0.27, P<0.001; β=0.41, P<0.001) and fear of negative evaluation also had a stronger predictive power on suicidal ideation ( β=0.08, P<0.001; β=0.14, P<0.001). Compared to the students with lower levels of meaning in life, for those who had higher levels of meaning in life, fear of negative evaluation had a weaker predictive power on suicidal ideation ( β=0.20, P<0.001; β=0.12, P<0.001). Conclusion:This study provides empirical evidence to the integrated motivational-volitional model of suicidal behavior. Results indicate that effects of perceived stress from interpersonal relations on suicidal ideation are moderated by meaning in life and intolerance of uncertainty. Reducing the perceived stress from interpersonal relations, lessening the level of intolerable of uncertainty, and carrying out intervention programs aiming at meaning in life are potential intervention ways to reduce the suicide risks of university freshmen.
ABSTRACT
Abstract The first Brazilian diagnosed with COVID-19 was identified on February 25th, resulting in a series of governmental actions to prepare the population for the effects of the pandemic. Nevertheless, geographic and socioeconomic characteristics of the country, and the strategies adopted may have contributed to generating a widespread feeling of uncertainty in the population; uncertainty about the disease, how to prevent it, its severity, and its impact on political and economic issues. This study was designed to investigate the relationship between intolerance of uncertainty and common mental health disorders. Participants were contacted via social media messages and encouraged to fill out an online questionnaire with socioeconomic questions, a short measure of intolerance of uncertainty (IUS-12), and a measure of mental health indicator (DASS-21). With a sample of 924 participants from Sergipe, Brazil, three binomial logistic regressions were performed, one for each DASS-21 outcome, categorized by a median. The women in the sample showed a higher probability of having stress, anxiety and depression scores above the median. Over the entire sample, both subscales of IUS-12 were significantly and positively related to all three DASS-21 subscales. These findings are discussed in the context of mental health during a pandemic, and future directions for research are also presented.
Resumo O primeiro brasileiro diagnosticado com COVID-19 foi identificado dia 25 de fevereiro, resultando em uma série de ações governamentais para preparar a população para os efeitos da pandemia. No entanto, características geográficas e socioeconômicas do país, e as estratégias adotadas, podem ter contribuído para a criação de uma sensação generalizada de incerteza na população; incerteza a respeito da doença, como preveni-la, sua gravidade, e seu impacto em questões políticas e econômicas. Este estudo foi elaborado para investigar a relação entre Intolerância à Incerteza e transtornos mentais comuns. Os participantes foram contactados por mensagens em redes sociais e convidados a preencher um questionário online com questões socioeconômicas, um instrumento breve de Intolerância a Incerteza (IUS-12) e um indicador de saúde mental (DASS-12). Com uma amostra de 924 participantes de Sergipe, Brasil, três regressões logísticas binomiais foram realizadas, uma para cada desfecho do DASS21, categorizados pela mediana. As mulheres da amostra apresentaram maior probabilidade de escores estresse, ansiedade e depressão acima da mediana. Em toda a amostra, ambas subescalas da IUS-12 foram significativa e positivamente relacionadas às três subescalas da DASS-12. Estes achados são discutidos no contexto de saúde mental durante uma pandemia, e futuras direções de pesquisa também são apresentadas.

Abstract Introduction The Intolerance of Uncertainty Scale - Short Version (IUS-12) is a measure of trait intolerance of uncertainty. Objective The purpose of the present study was to conduct a cross-cultural adaptation of the IUS-12 for use in Brazil and to investigate the scale's psychometric properties. Methods The research was conducted via an online research platform with a sample (n = 704; 80.1% female and 19.9% male) from different states in all five regions of Brazil. Participants were adults between 18 and 59 years of age (mean = 26.74; standard deviation = 8.36) who completed the Brazilian version of the IUS-12 online along with other anxiety-related measures. Results Confirmatory factor analysis demonstrated that the original two-dimensional structure fit the sample well. The total score for the scale had good internal consistency (Cronbach's alpha [α] = 0.88), as did both subscales (i.e. Prospective IU α = 0.79; Inhibitory IU α = 0.86). Conclusions The results demonstrated strong positive correlations with measures of anxiety-related constructs, contributing to the transdiagnostic understanding of IU. The IUS-12 appears to be a useful tool for assessment of IU and its availability has several implications of theoretical importance and practical utility for understanding of psychopathology and uncertainty.

Objective: To investigate the level of intolerance of uncertainty (IU) and possible related factors in the patients with anxiety disorders. Methods: The patients' diagnosis was made according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM- ). Thirty-five cases of generalized anxiety disorder (GAD), 15 cases of panic disorder (PD) and 31 healthy controls (HC group) were recruited at the same time. IU level was assessed by using the Chinese version of Intolerance of Uncertainty Scale (IUS). The characteristics of anxiety symptoms, depressive symptoms and body perception were assessed by Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD) and Body Perception Questionaire (BPQ), respectively. Results: The IU levels of both GAD group and PD group were significantly higher than those of HC group (P=0.000). There was no significant difference in IU levels between GAD group and PD group (P=0.491). The IU levels of GAD patients were positively correlated with HAMA-somatic anxiety (r=0.377, P=0.025) and BPQ-awareness (r=0.342, P=0.044). Conclusion: The patients with anxiety disorders have elevated IU levels, compared with healthy people. Possibly, somatic anxiety and body perception-awareness are related factors to IU in GAD patients.
ABSTRACT
El trastorno por estrés postraumático (TEPT) tiene una importante prevalencia en la población, por lo que conocer los mecanismos psicológicos para la vulnerabilidad y el mantenimiento del trastorno es claramente relevante. Entre dichos mecanismos, se ha postulado el constructo de malestar emocional como transdiagnóstico a diversos trastornos mentales. El objetivo del presente estudio fue poner a prueba un modelo hipotético que analizaba la asociación entre tres variables pertenecientes a dicho constructo (evitación experiencial, tolerancia al malestar e intolerancia a la incertidumbre inhibitoria) y el TEPT. Participaron 328 estudiantes universitarios (74.7% mujeres y 25.3% hombres, con una media de edad de 21 años) que habían experimentado al menos un acontecimiento traumático de acuerdo con los criterios del DSM-5, quienes completaron una batería de cuestionarios. Se efectuó un análisis de ecuaciones estructurales cuyos resultados apoyaron parcialmente el modelo hipotético. La evitación experiencial mostró asociarse positiva y significativamente con la tolerancia al malestar, la intolerancia a la incertidumbre inhibitoria y los síntomas del TEPT. La tolerancia al malestar también se vinculó de forma positiva y significativa con dichos síntomas. Sin embargo, la intolerancia a la incertidumbre inhibitoria no mostró relación con esta sintomatología. En apoyo a la evidencia empírica precedente, los hallazgos de este estudio inciden en el papel de la evitación experiencial y la tolerancia al malestar como variables moderadoras de la sintomatología postraumática. Asimismo, apuntan hacia la necesidad de considerar estas variables en las intervenciones psicológicas para el tratamiento del TEPT
Post-traumatic stress disorder or PTSD has an important prevalence in the population, so knowing the psychological mechanisms of vulnerability and maintenance of this disorder is clearly relevant. Among those mechanisms, the emotional distress construct has been postulated as a trans-diagnostic tool related to different mental disorders. The objective of the present study was to test a hypothetical model for the analysis of the association between three variables of this construct (experiential avoidance, distress tolerance, and inhibitory uncertainty intolerance) and PTSD. The subjects of study amounted to 328 university students (74.7% women and 25.3% men, with a median age of 21) who had experienced at least one traumatic event according to the DSM-5 criteria. They were made to complete a set of questionnaires. A structural equation analysis was carried out, with results partially coincident with the hypothetical model. Exponential avoidance showed a positive and significant association with distress tolerance, inhibitory uncertainty intolerance and PTSD symptoms. Distress tolerance was also associated with these symptoms in a positive and significant way. However, inhibitory uncertainty intolerance was not associated with this symptomatology. Following the preexisting empirical evidence, the findings of this study have an impact on the role of experiential avoidance and distress tolerance, as variables that moderate post-traumatic symptomatology. Furthermore, the findings point to the need to consider these variables in psychological interventions for the treatment of PTSD

Objective To explore composited multiple mediating effects of intolerance of uncertain-ty,generalized anxiety symptoms and obsessive-compulsive symptoms between neuroticism and insomnia. Methods In this study,405 university students were evaluated using several questionnaires,including Ath-ens Insomnia Scale,Intolerance of Uncertainty Scale,the Penn State Worry Questionnaire and Obsessive-com-pulsive. Inventory-Revised and Eysenck Personality Questionnaire-Revised Short Scale for Chinese. Results The scores of Athens Insomnia Scale(4. 07±2. 57),Intolerance of Uncertainty Scale(72. 33±14. 42),The Penn State Worry Questionnaire(40. 57±10. 35),Compulsive Activity Checklist-Revised(1. 60±1. 45) and Eysenck Personality Questionnaire-Revised Short Scal(4. 86±3. 22) were positively correlated with each other(r=0. 18~0. 64,P<0. 01). Model fit indices in SEM were χ2/df=2. 15,P>0. 05;CFI=0. 99;GFI=0. 99;NFI=0. 99;NNFI(TLI)=0. 97;RMSEA=0. 05. The results indicated that neuroticism directly af-fected insomnia ( effect size 0. 125), neuroticism affects insomnia through generalized anxiety symptoms (effect size 0. 082) and obsessive-compulsive symptoms( effect size 0. 053) respectively. Thus,generalized anxiety symptoms and obsessive-compulsive symptoms were parallel mediators. Neuroticism affects general-ized anxiety symptoms through intolerance of uncertainty, and then affected the insomnia ( effect size 0. 022). And neuroticism affected obsessive-compulsive symptoms through intolerance of uncertainty, and then affected the insomnia ( effect size 0. 014). Conclusion The neuroticism personality of university students can influence insomnia through the multiple mediation model of intolerance of uncertainty,general-ized anxiety symptoms and obsessive-compulsive symptoms.
ABSTRACT
Objective To investigate the correlation between occupational stress,uncertain endur-ance and job burnout of pre-hospital emergency nurses. Methods A total of 380 pre-hospital emergency nurses were recruited by stratified cluster sampling method.The occupational burnout scale(MBI)including emotional exhaustion(EE),depersonalization(D)and diminished personal accomplishment(PA),the In-tolerance of Uncertainty Scale(IUS),the Nursing Stressor Scale(NSS)including stresses associated with nurse expectations(NSS1),with family(NSS2),with interpersonal relationship(NSS3),with nature of work (NSS4),with patient(NSS5)and with work load(NSS6)were applied for all subjects.Results The pre-hospital emergency nurses who had worked less than 3 years got the higher EE score(33.58 ± 4.34)and higher PA score(26.98±4.31)than those who had worked 3 to 10 year(22.33±4.05,16.14±4.28,P<0.05) or longer than 10 years(21.50±4.36,16.81±4.36,P<0.05).Nurses got higher EE score(33.82±4.28,22.96 ±4.39,21.04±4.62,P<0.05),and higher PA scores(27.02±4.21,16.04±4.31,16.01±4.30,P<0.05)than the nurse practitioner or above levels.People whose monthly income were below 0.3 million got higher PA scores than those whose monthly income were 0.3 million or more(26.75±4.24,16.47±4.27,17.11±4.34,P<0.05).People who got degrees of bachelor or above had PA scores which was more than people who got de-grees under bachelor(26.33±4.36,17.24±4.28,P<0.05).Regression analysis showed that the multiplication score between IUS and NSS1 had the interaction effect with EE and D scores(β=0.33,0.33,P<0.05); the multiplication score between IUS and NSS5 had the interaction effect with EE and D scores(β=0.31,0.30, P<0.05)and the multiplication score between IUS and NSS3 had the interaction effect with D scores(β=0.34,P<0.05).Conclusion The pre-hospital emergency nurses'job burnout varies according to their length of service,job title,educational level and salary,and is also influenced by the combination of occupational stress and uncertain endurance.
ABSTRACT
OBJECTIVE: Intolerance of uncertainty (IU) is a transdiagnostic construct in various anxiety and depressive disorders. However, the relationship between IU and panic symptom severity is not yet fully understood. We examined the relationship between IU, panic, and depressive symptoms during mindfulness-based cognitive therapy (MBCT) in patients with panic disorder. METHODS: We screened 83 patients with panic disorder and subsequently enrolled 69 of them in the present study. Patients participating in MBCT for panic disorder were evaluated at baseline and at 8 weeks using the Intolerance of Uncertainty Scale (IUS), Panic Disorder Severity Scale-Self Report (PDSS-SR), and Beck Depression Inventory (BDI). RESULTS: There was a significant decrease in scores on the IUS (p<0.001), PDSS (p<0.001), and BDI (p<0.001) following MBCT for panic disorder. Pre-treatment IUS scores significantly correlated with pre-treatment PDSS (p=0.003) and BDI (p=0.003) scores. We also found a significant association between the reduction in IU and PDSS after controlling for the reduction in the BDI score (p<0.001). CONCLUSION: IU may play a critical role in the diagnosis and treatment of panic disorder. MBCT is effective in lowering IU in patients with panic disorder.

Este artículo informa la adaptación lingüística y el análisis de las propiedades psicométricas de la Escala de Intolerancia a la Incertidumbre (EII) en población de Buenos Aires. La EII evalúa la intolerancia a la incertidumbre (II) que es uno de los componentes principales del trastorno de ansiedad generalizada (TAG) según el modelo teórico de Dugas. La intolerancia a la incertidumbre se define como una disposición característica que resulta de un conjunto de pensamientos negativos sobre la incertidumbre. La Escala de Intolerancia a la Incertidumbre (EII) está compuesta por 27 ítemes que se responden con un formato tipo Likert de cinco opciones de respuesta. Se analizaron los datos obtenidos de una muestra de 320 participantes, residentes de la Ciudad Autónoma de Buenos Aires y el Gran Buenos Aires (República Argentina). Se obtuvieron correlaciones significativas con medidas criterio de preocupación (r = .44; p = .000) y ansiedad como estado (r = .36; p = .000) y como rasgo (r = .58; p = .000). Se estudió la estructura de la escala con el análisis de componentes principales y se obtuvieron dos factores que explican el 41.07% de la variancia total. Con respecto a la fiabilidad, los resultados indican una excelente consistencia interna de los ítemes igual a .93 y una estabilidad test-retest luego de cinco semanas, igual a .47. No se registraron diferencias significativas en las puntuaciones de la escala según la edad y el sexo. En su conjunto, los resultados obtenidos en la investigación realizada son concordantes con los hallazgos de investigaciones anteriores. Dado que la II constituye un factor de vulnerabilidad para el TAG, es de utilidad contar con un cuestionario adaptado a la población local.
The purpose of this paper is to report as regards the linguistic and cultural adaptation and psychometric properties of the Intolerance of Uncertainty Scale (IUS, for its acronyms in English) in the adult population of Buenos Aires (Republica Argentina). The IUS assesses the intolerance of uncertainty (IU), which is one of the principal components of the generalized anxiety disorder (GAD) according to the theoretical model of Dugas. IU has been defined as a dispositional characteristic that results from a set of negative beliefs about uncertainty and it has been proposed as a cognitive vulnerability factor for worry and GAD. Furthermore it may be defined more specifically as the excessive tendency of an individual to consider it unacceptable that a negative event may occur, however small the probability of its occurrence. In general, intolerance of uncertainty may be conceptualized as the way an individual perceives information in uncertain situations and responds to said information with a set of emotional, cognitive and behavioral responses. The IUS is composed of 27 items related to the idea that uncertainty is unacceptable, leads to frustration and the inability to take action and it reflected badly on a person. Participants rate items on a five-point Likert scale ranging from 1: not at all characteristic of me to 5: entirely characteristic of me. Higher scores on the IUS indicate greater intolerance of uncertainty. The original French version of the IUS was developed in 1994 to assess emotional, cognitive, and behavioral reactions to ambiguous situations, implications of being uncertain, and attempts to control the future. In 2002, the IUS was translated from French to English. Similar to the original French measure, the English translation had shown excellent internal consistency and temporal stability. It has demonstrated convergent, criterial, and discriminant validity. On this study, the IUS translated into Spanish by three independent translators. The content validity was assessed through the use of three independent judges who had broad knowledge of anxiety disorder. The preliminary version was tested with a sample of 90 participants. The research was a descriptive and correlational study, with a transversal design The participants completed the following questionnaires: the Beck Depression Inventory II (BDI-II), the Penn State Worry Questionnaire (PSWQ) and the State-Trait Anxiety Inventory (STAI). Data obtained from a sample of 320 participants (168 females and 152 males) of the Ciudad and Provincia de Buenos Aires has been analyzed. Data analysis was conducted using Statistical Package for the Social Sciences (SPSS) - Version 22 software. In relation to the evidence of validity, significant correlations were obtained with worry (r = .44; p = .000) and anxiety as a state (r = .36; p = .000) and trait (r = .58; p = .000). The exploratory data analysis regarding the factor structure of the scale and dimensions of the construct indicated two factors that explain 41.07 % of the total variance. On the one hand, concerning the consistency of this scale, the results show an excellent internal consistency (.93) and a fairly strong test-retest reliability over a five-week period of .47. On the other hand, significant differences were not registered in the punctuations of the scale according to age and sex, and these findings are consistent with previous research. As a whole, the results obtained from the present investigation are consistent with the findings of previous investigations. Given that the IU constitutes a factor of vulnerability for the TAG, it is useful to rely on a questionnaire adapted to the local population. To conclude, the present study has demonstrated the sound psychometric properties of the Spanish version of the IUS.
ABSTRACT
Objective To analyze the reliability and validity of the Chinese version of the intolerance of uncertainty scale (IUS).Methods 878 college students were investigated,then the data were analysis by SPSS13.0 and Amos17.0.Results The project analysis and exploratory factor analyzed showed that,the Chinese version of the intolerance of uncertainty scale consisted of 24 projects and four dimensions,which could account for over 50.355％ of tolal varance.The confirmatory factor analysis further revealed the structure of four-dimensional scale (x2 =660.645,x2/df =2.686,NFI =0.806,NNFI ＝ 0.817,CFI =0.837,RMSEA =0.071).The score of the Chinese version of the intolerance of uncertainty scale was significantly correlated with all criterion,and the correlation coefficients to criterion ranged from-0.288 to-0.481,so the scale had the better criterion validity.The Cronbach's a coefficient of the Chinese version of the intolerance of uncertainty scale was 0.889,and the test-retest stability coefficient was 0.687.Conclusion The Chinese version of the intolerance of uncertainty scale has good psychometric quality,and can be used in Chinese college students.
ABSTRACT
OBJECTIVES: Risk taking has been implicated in the development of various psychiatric disorders. Previous studies have indicated that risk taking behavior is associated with high levels of impulsiveness. Risk taking entail uncertain situation that outcome probability is unknown. This study tested impulsivity, intolerance of uncertainty and risk taking behavior. METHODS: A total of 73 participants completed a test battery comprised of the UPPS-P scale as a psychometric measurement of five dimensions of impulsivity, Intolerance of Uncertainty Scale, and Balloon Analog Risk Task (BART) as a behavioral measure of risk taking. The Pearson correlation analysis was used. RESULTS: The sensation seeking factor was positively correlated with BART measure (r = 0.27, p = 0.02). Specifically, the relationship between sensation seeking and BART was significant in females. CONCLUSIONS: Among the five factors of UPPS-P, only the sensation seeking factor predicts risk taking propensity.
ABSTRACT
Objective To explore the reliability and validity of the Chinese revised version of the Intolerance of uncertainty scale(IUS).Methods A total of 930 college students completed the IUS.45 college students participated in the retest 3 weeks later.The self-rating anxiety scale (SAS) and the self-rating depression scale (SDS) were used as criterions for assessment of the validity of the Chinese revised version of IUS.Results The Chinese revised version of IUS contained 21 items.Exploratory factor analysis found a two-factor model (negative belief and emotional experience,behavioral dysfunction and negative self-reference) with a cumulative variance contribution rate of 42.09％.And the results of Confirmatory factor analysis (x 2/df =2.82,GFI =0.90,TLI =0.90,CFI =0.91,RMSEA =0.065) indicated that this model provided a reasonable good fit for Chinese college students.The Cronbach α of internal consistency reliability were good for IUS and two subscales,which were 0.929,0.885 and 0.864,respectively.The test-retest reliabilities for IUS and two subscales were 0.782,0.766 and 0.714 respectively.The IUS scores were positively correlated with the scores of SAS and SDS (r =0.489 ～0.575,P ＜ 0.001).Conclusion It suggests that the Chinese revised version of IUS has good reliability and validity,which is qualified enough for relevant research and applications for Chinese adults.
