emotion dysregulation as an explanatory factor in the relation between Negative Affectivity and non medical use of opioid in a diverse young adult sample
Addictive Behaviors, 2019Co-Authors: Jafar Bakhshaie, Michael J Zvolensky, Brooke Y Kauffman, Julia D Buckner, Andrew H Rogers, Nhan Tran, Joseph W DitreAbstract:Abstract The non-medical use of prescription opioids is an area of increasing public health concern, particularly among young college-age adults (ages 18–25) who demonstrate an increased risk of opioid-related problems. Negative mood states are consistently associated with more severe non-medical use of opioid. Emotion dysregulation defined an impaired ability to understand, evaluate, and differentiate one's emotions, and access strategies to regulate them could play an explanatory role in this association. The present study examined the potential explanatory role of emotion dysregulation in the relationship between Negative Affectivity and non-medical use of prescription opioid among a racially/ethnically diverse young adult sample (N = 2080, 78.7% female, Mage = 21.9, SD = 4.9) attending a large southwestern state university, and across the two sub-samples of individuals with and without pain. Results indicated that emotion dysregulation explained, in part, the association between Negative Affectivity and non-medical use of opioid-related variables, including self-reported addiction to opioids, denial of opioid prescription by a healthcare provider, and family concerns about participant's opioid use. These indirect effects were comparable across individuals with and without pain. Findings suggest that targeting emotion dysregulation may be one therapeutic strategy to reduce non-medical use of opioid in the context of Negative Affectivity among college students.

Negative Affectivity as a mechanism underlying perceived distress tolerance and cannabis use problems barriers to cessation and self efficacy for quitting among urban cannabis users
Addictive Behaviors, 2018Co-Authors: Kara Manning, Michael J Zvolensky, Daniel J Paulus, Julianna Hogan, Julia D Buckner, Samantha G FarrisAbstract:Cannabis use rates continue to rise in the United States and currently cannabis is among the most widely used substances in the world. Cannabis use is associated with several mental health problems, low educational attainment, low income, and underemployment. The current study explored the tendency to experience Negative affect (Negative Affectivity) as a factor accounting for the association between perceived distress tolerance and problems related to the use of cannabis. Participants included 203 urban adult daily cannabis users (29.2% female, M=37.7years, 63% African American). Results indicated that there was a significant indirect effect of distress tolerance via Negative Affectivity in terms of cannabis use problems (b=-0.58, 95%CI [-1.14, -0.21]), cannabis withdrawal (b=-0.65, 95%CI [-1.36, -0.21]), self-efficacy for quitting (b=-0.83, 95%CI [-1.85, -0.22]), and perceived barriers for cannabis cessation (b=-0.71, 95%CI [-1.51, -0.24]). The present data provide novel empirical evidence suggesting Negative Affectivity may help explain the relation between perceived distress tolerance and an array of clinically significant cannabis use processes. Intervention programming for daily cannabis users may benefit from targeting Negative Affectivity to facilitate change in cannabis use processes among users who tend to perceive that they are less capable of tolerating distress.

Interactive Effect of Negative Affectivity and Rumination in Terms of Mental Health Among Latinos in Primary Care
Journal of Racial and Ethnic Health Disparities, 2016Co-Authors: Michael J Zvolensky, Daniel J Paulus, Jafar Bakhshaie, Monica Garza, Daniel Bogiaizian, Zuzuky Robles, Chad Lemaire, Melissa Ochoa-perez, Amelia Aldao, Anahi ColladoAbstract:The present investigation examined the interactive effects of rumination and Negative Affectivity in relation to anxiety and depressive symptoms and psychopathology among 245 Latino adults ( M _age = 39.7, SD = 11.4; 86.9 % female; 97.6 % reported Spanish as their first language) attending a community-based primary healthcare clinic. As expected, there was a significant interaction between rumination and Negative Affectivity for depressive, suicidal, social anxiety, anxious arousal symptoms, number of mood and anxiety disorders, and disability among the primary care Latino sample. Inspection of the interaction forms indicated a high degree of conceptual similarity. Specifically, rumination was related to greater levels of suicidal symptoms, social anxiety, anxious arousal, number of mood and anxiety disorders, and disability among individuals with higher, but not lower, levels of Negative Affectivity. The form of the interaction for depressive symptoms was in line with this pattern, but more extreme; rumination was related to greater levels of depressive symptoms among individuals with both higher and lower levels of Negative Affectivity. Together, these data provide novel empirical evidence suggesting that there is clinically relevant interplay between rumination and Negative Affectivity in regard to a relatively wide array of anxiety and depressive variables among Latinos in a primary care medical setting.

interactive effect of Negative Affectivity and anxiety sensitivity in terms of mental health among latinos in primary care
Psychiatry Research-neuroimaging, 2016Co-Authors: Michael J Zvolensky, Daniel J Paulus, Jafar Bakhshaie, Monica Garza, Melissa Ochoaperez, Angela Medvedeva, Daniel Bogiaizian, Zuzuky Robles, Kara ManningAbstract:From a public health perspective, primary care medical settings represent a strategic location to address mental health disapirty among Latinos. Yet, there is little empirical work that addresses affective vulnerability processes for mental health problems in such settings. To help address this gap in knowledge, the present investigation examined an interactive model of Negative Affectivity (tendency to experience Negative mood states) and anxiety sensitivity (fear of the Negative consequences of aversive sensations) among a Latino sample in primary care in terms of a relatively wide range of anxiety/depression indices. Participants included 390 Latino adults (Mage=38.7, SD=11.3; 86.9% female; 95.6% reported Spanish as first language) from a primary care health clinic. Primary dependent measures included depressive, suicidal, social anxiety, and anxious arousal symptoms, number of mood and anxiety disorders, and disability. Consistent with prediction, the interaction between Negative Affectivity and anxiety sensitivity was significantly related to suicidal, social anxiety, and anxious arousal symptoms, as well as number of mood/anxiety diagnoses and disability among the primary care Latino sample. The form of the interactions indicated a synergistic effect, such that the greatest levels of each outcome were found among those with high Negative Affectivity and high anxiety sensitivity. There was a trending interaction for depressive symptoms. Overall, these data provide novel empirical evidence suggesting that there is a clinically-relevant interplay between anxiety sensitivity and Negative Affectivity in regard to the expression of anxiety and depressive symptoms among a Latino primary care sample.

an evaluation of anxiety sensitivity emotional dysregulation and Negative Affectivity among daily cigarette smokers relation to smoking motives and barriers to quitting
Journal of Psychiatric Research, 2008Co-Authors: Adam Gonzalez, Michael J Zvolensky, Anka A Vujanovic, Teresa M Leyro, Erin C MarshallAbstract:The present investigation evaluated the relations between anxiety sensitivity and motivational bases of cigarette smoking, as well as barriers to quitting smoking, above and beyond concurrent substance use, Negative Affectivity, and emotional dysregulation among a community sample of 189 daily cigarette smokers (46% women; Mage = 24.97 years, SD = 9.78). Results indicated that anxiety sensitivity was significantly related to coping, addictive, and habitual smoking motives, as well as greater perceived barriers to quitting. These effects were evident above and beyond the variance accounted for by concurrent tobacco, alcohol, and marijuana use and discernable from shared variance with Negative Affectivity and emotional dysregulation. Emotional dysregulation was significantly related to stimulation, habitual, and sensorimotor smoking motives and greater perceived barriers to quitting, whereas Negative Affectivity was only significantly related to smoking for relaxation. These findings uniquely add to a growing literature suggesting anxiety sensitivity is an important and unique cognitive factor for better understanding clinically-relevant psychological processes related to cigarette smoking.

a structural equation model of the effects of Negative Affectivity leader member exchange and perceived job mobility on in role and extra role performance a chinese case
Organizational Behavior and Human Decision Processes, 1999Co-Authors: Chun Hui, Kenneth S Law, Zhen Xiong ChenAbstract:In this paper, we contrast the effects of leader-member exchange (LMX) with the effects of perceived job mobility on in-role performance and organizational citizenship behavior (OCB). We further model Negative Affectivity as the antecedent of both LMX and perceived job mobility and suggest that LMX and perceived job mobility mediated the relationship between Negative Affectivity and performance. We obtained matching data from supervisor and subordinates in a major battery manufacturing company in southern China. Subordinates provided the Negative Affectivity, perceived job mobility, and LMX assessment, and their immediate supervisors provided the in-role performance and OCB assessment. Results from a structural equation analysis show that both LMX and perceived job mobility predicted OCB. Instead of being a direct antecedent of OCB, the relationship between Negative Affectivity and OCB is found to be mediated by LMX and perceived job mobility. Theoretical implications of the results are discussed.

endogenous pain modulation association with resting heart rate variability and Negative Affectivity
Pain Medicine, 2018Co-Authors: Maaike Van Den Houte, Ilse Van Diest, Katleen Bogaerts, Lukas Van Oudenhove, Omer Van Den BerghAbstract:Objectives Several chronic pain syndromes are characterized by deficient endogenous pain modulation as well as elevated Negative Affectivity and reduced resting heart rate variability. In order to elucidate the relationships between these characteristics, we investigated whether Negative Affectivity and heart rate variability are associated with endogenous pain modulation in a healthy population. Design, subjects, and methods An offset analgesia paradigm with noxious thermal stimulation calibrated to the individual's pain threshold was used to measure endogenous pain modulation magnitude in 63 healthy individuals. Pain ratings during constant noxious heat stimulation to the arm (15 seconds) were compared with ratings during noxious stimulation comprising a 1 °C rise and return of temperature to the initial level (offset trials, 15 seconds). Offset analgesia was defined as the reduction in pain following the 1 °C decrease relative to pain at the same time point during continuous heat stimulation. Results Evidence for an offset analgesia effect could only be found when noxious stimulation intensity (and, hence, the individual's pain threshold) was intermediate (46 °C or 47 °C). Offset analgesia magnitude was also moderated by resting heart rate variability: a small but significant offset effect was found in participants with high but not low heart rate variability. Negative Affectivity was not related to offset analgesia magnitude. Conclusions These results indicate that resting heart rate variability (HRV) is related to endogenous pain modulation (EPM) in a healthy population. Future research should focus on clarifying the causal relationship between HRV and EPM and chronic pain by using longitudinal study designs.

Negative Affectivity and the influence of suggestion on asthma symptoms
Journal of Psychosomatic Research, 2004Co-Authors: Claudia Put, Omer Van Den Bergh, Elke Van Ongeval, Steven De Peuter, Maurits Demedts, Geert VerledenAbstract:Abstract Objective To investigate the effect of suggestion on subjective and objective asthma symptoms as a function of Negative Affectivity of the patients. Methods Asthmatics ( n =32) took puffs from three separate placebo inhalers, being described as an inert (practice) substance, a bronchoconstrictor, and a bronchodilator. Negative Affectivity, social desirability, probability of medication-intake, intensity of asthma symptoms and total respiratory resistance were measured at onset. The latter three measures were repeated after each trial. Heart rate, end tidal PCO 2 , and breathing behaviour were measured during each trial. Results Asthmatics with high Negative Affectivity had overall more intense asthma symptoms. They also reported more airway obstruction after suggested bronchoconstriction and less after suggested bronchodilation, whereas persons with low Negative Affectivity did not show such variation. These effects were unrelated to social desirability. Respiratory symptoms correlated with the odds of medication intake. Neither Negative Affectivity nor suggestion influenced lung function and only breathing parameters under voluntary control changed as a function of suggestion. Conclusion Self-reported symptoms of asthmatics with high Negative Affectivity are more influenced by suggestion than those of patients with low Negative Affectivity.

emotional vulnerability and mindfulness a preliminary test of associations among Negative Affectivity anxiety sensitivity and mindfulness skills
Cognitive Behaviour Therapy, 2007Co-Authors: Laura Mckee, Michael J Zvolensky, Sondra E Solomon, Amit Bernstein, Ellen W LeenfeldnerAbstract:This study evaluated associations between general (Negative Affectivity) and specific (anxiety sensitivity) factors that may relate to the mindfulness skill domains assessed by the Kentucky Inventory of Mindfulness Skills. Participants were 154 young adults (88 females; Mage = 22.4 years, SD = 7.9) recruited from the community. Partially consistent with predictions, higher levels of Negative Affectivity were significantly associated with lower levels of Awareness, Acceptance, and Describe mindfulness skills, and higher levels of anxiety sensitivity were significantly associated with lower levels of Awareness and Acceptance mindfulness skills. Additionally, Negative Affectivity and anxiety sensitivity each demonstrated unique relations to participants' ability to experience the present state without evaluating or judging its content (Accept factor), after accounting for their shared variance, but only anxiety sensitivity demonstrated a unique association to the Act with Awareness factor independent of vari...
