Anàlisi de les relacions entre els trets de personalitat i la disfonia

Vila Rovira, Josep Maria 15 December 2011 (has links)
En l'experiència clínica, els foniatres i logopedes especialitzats en trastorns de la veu han afirmat que les disfonies tenen relació amb la personalitat del pacient. Estudis previs de Roy i Bless indiquen una relació entre els trets de personalitat neuroticisme i extraversió, definits per Eysenck, i les disfonies funcionals i els nòduls vocals. Aquests estudis proposen que les teories de Gray poden explicar aquesta relació. Gray proposa l'existència de dos sistemes biològics d'activació i d'inhibició conductual que responen a una major sensibilitat del subjecte a les recompenses i els càstigs, respectivament. El 2011, Torrubia et al. presenten, un qüestionari per a la valoració d'aquests dos sistemes. Partint dels treballs de Roy i Bless, l'estudi que presentem pretén aportar evidències sobre la influència dels trets de personalitat en la presència d'alteracions de la veu. S'han administrat els qüestionaris EPQ-RS d'Eysenck i SCSRQ de Torrubia a un grup experimental de 141 pacients atesos per alteracions de la veu i ha un grup control de 99 persones sense alteracions vocals. A tots ells se'ls va administrar també el qüestionari Voice Handicap Index-10 i es van recollir diverses mostres de la seva veu que van ser analitzades amb el programa MDVP per obtenir el paràmetre Dysphonia Severity Index descrit per Wuyts, i van ser valorades amb el paràmetre Grade del GRBAS d'Hirano per cinc logopedes experts en alteracions vocals. Els resultats han estat analitzats amb el paquet estadístic PASW 18. Els resultats mostren diferències estadísticament significatives entre el grup experimental i el grup control en relació al tret neuroticisme en el test EPQ (z = 6.951, p <.01) i en relació a la sensibilitat al càstig en el test SCSRQ (z = 2.207; p <.05). Les dades mostren també diferències estadísticament significatives entre els dos grups pel que fa als valors del DSI (z = 9.320, p <.01). Per a aquesta mesura s'ha establert un valor de tall, amb la corba ROC, en la puntuació 3.7. També s'han obtingut diferències significatives en les puntuacions totals del VHI-10 (z = 10.351, p <.001) i un valor de tall de 7. El paràmetre G ha presentat diferències significatives (z = 10.959, p <.001) i un valor de tall en la puntuació 1. Les tres mesures de la disfonia correlacionen amb els resultats dels qüestionaris de personalitat per als trets neuroticisme (DSI rs = -. 437, p> .001; VHI-10 rs =.416, p> .001; paràmetre G rs = .446, p> .001) i sensibilitat al càstig (VHI-10 rs = .231, p> .01; paràmetre G rs = .144, p> .05). Els resultats confirmen les informacions aportades per investigacions anteriors respecte a la influència del neuroticisme en la disfonia. En el mateix sentit, podem concloure que el tret introversió està més present en la població amb alteracions de la veu. Els resultats de l'escala de sensibilitat al càstig permeten pensar que les teories de Gray poden orientar sobre els factors emocionals en les alteracions vocals. Així mateix, els resultats permeten concloure que els instruments de mesura de la qualitat vocal són fiables, complementaris i vàlids per a la discriminació de persones que pateixen alteracions de la veu. / En la experiencia clínica, los foniatras y logopedas especializados en trastornos de la voz han afirmado que las disfonías tienen relación con la personalidad del paciente.

En 2011, Torrubia et al. presentaron un cuestionario para la valoración de estos dos sistemas. Partiendo de los trabajos de Roy y Bless, el estudio que presentamos pretende aportar evidencias sobre la influencia de los rasgos de personalidad en la presencia de alteraciones de la voz. Se han administrado los cuestionarios EPQ-RS de Eysenck y SCSRQ de Torrubia a un grupo experimental de 141 pacientes atendidos por alteraciones de la voz y a un grupo control de 99 personas sin alteraciones vocales. A todos ellos se les administró también el cuestionario Voice Handicap Index-10 y se recogieron diversas muestras de su voz que fueron analizadas con el programa MDVP para la obtención del parámetro Dysphonia Severity Index descrito por Wuyts, y fueron valoradas con el parámetro Grade del GRBAS de Hirano por cinco logopedas expertos en alteraciones vocales. Los resultados han sido analizados con el paquete estadístico PASW 18. Los resultados muestran diferencias estadísticamente significativas entre el grupo experimental y el grupo control en relación al rasgo neuroticismo en el test EPQ (z = 6.951; p< .01) y en relación a la sensibilidad al castigo en el test SCSRQ (z = 2.207; p< .05). Los datos muestran también diferencias estadísticamente significativas entre los dos grupos con respecto a los valores del DSI (z = 9.320, p < .01). Para esta medida se ha establecido un valor de corte, con la curva ROC, en la puntuación 3.7. También se han obtenido diferencias significativas en las puntuaciones totales del VHI-10 (z = 10.351; p< .001) y un valor de corte de 7. El parámetro G ha presentado diferencias significativas (z = 10.959; p< .001) y un valor de corte en la puntuación 1. Las tres mediciones de la disfonía correlacionan con los resultados de los cuestionarios de personalidad para los rasgos neuroticismo (DSI rs = -.437, p>.001; VHI-10 rs = .416, p>0.001; parámetro G rs = .446, p>0.001) y sensibilidad al castigo (VHI-10 rs = .231, p>.01; parámetro G rs = .144, p>.05). Los resultados confirman las informaciones aportadas por investigaciones anteriores respecto a la influencia del neuroticismo en la disfonía. En el mismo sentido, podemos concluir que el rasgo introversión está más presente en la población con alteraciones de la voz. Los resultados de la escala de sensibilidad al castigo permiten pensar que las teorías de Gray pueden orientar sobre los factores emocionales en las alteraciones vocales. Asimismo, los resultados permiten concluir que los instrumentos de medida de la calidad vocal son fiables, complementarios y válidos para la discriminación de personas que sufren alteraciones de la voz. / In clinical experience, phoniatricians and speech therapists who specialize in voice disorders have argued that dysphonia is related to the patient's personality. Previous studies by Roy and Bless indicate a relationship between the personality traits neuroticism and extraversion, defined by Eysenck, and functional dysphonia and vocal nodules. These studies suggest that Gray's theories can explain this relationship. Gray proposes the existence of two biological systems of activation and behavioral inhibition, which respond to increased sensitivity of the subject to reward and punishment, respectively. In 2011, Torrubia et al. presented a questionnaire for the assessment of these two systems. Based on the work of Roy and Bless, the study presented aims to provide evidence on the influence of personality traits in the presence of voice disorders. Administered questionnaires were Eysenck's EPQ-RS and SCSRQ of Torrubia to an experimental group of 141 patients with voice disorders and a control group of 99 people with no vocal alterations. All of them answered the Voice Handicap Index-10 questionnaire and several samples of their voices were analyzed with the MDVP program so as to obtain Dysphonia Severity Index parameter described by Wuyts. These samples were evaluated with the parameter Grade of Hirano’s GRBAS by five speech pathologists specialized in voice disorders. The results were analyzed using the statistical package PASW 18. The results showed statistically significant differences between the experimental and control groups in relation to trait neuroticism on the EPQ test (z = 6951, p <.01) and in relation to sensitivity to punishment in SCSRQ test (z = 2207; p <.05). The data also showed statistically significant differences between the two groups regarding DSI values (z = 9320, p <.01). For this measure cutoff with ROC curve has been established in the score 3.7. Significant differences were also obtained in total scores of HIV-10 (z = 10,351, p <.001) and a cutoff value of 7. The parameter G has presented significant differences (z = 10,959, p <.001) and a cutoff in the score 1. All three measures of dysphonia correlated with the results of the questionnaires of personality traits neuroticism (r = -. 437 DSI, p> .001; VHI-10 r = .416, p> .001; parameter G r = .446, p <.001) and sensitivity to punishment (VHI-10 r = .231, p> 0.01; parameter G r = .144, p> .05). The results confirm the information provided by previous research on the influence of neuroticism in dysphonia. Also, we can conclude that introversion trait is more present in people with voice disorders. The relationship between the results of the sensitivity scale to punishment suggests that Gray's theories can shed some light on emotional factors in voice disorders. Finally, the results suggest that measurement instruments used for voice quality are reliable, complementary and valid for the discrimination of people with voice disorders.

Kvinnliga arbetstagare i sjuk- och äldrevården - faktorer som kan påverka graden av upplevd stress utanför arbetstid

Bergström, Hanna, Bäck, Annika January 2007 (has links)
The aim of this study was to examine the relations between women’s perceived stress off the job (dependent variable), responsability for household chores, emotional support, number of children living at home, neuroticism and age (independent variables). Comparisons between the present sample and two independent samples from previous research were made with regard to perceived stress and neuroticism. The sample of this study consisted of 186 women working in the fields of health care and geriatric care. The results showed that perceived stress correlated positively with neuroticism and number of children and negatively with emotional support, though the effectsizes for number of children and emotional support were fairly small. Neuroticism was the strongest predictor for perceived stress. Implemented comparisons showed that the present sample reported significantly higher levels of perceived stress and neuroticism than the two independent samples. Keywords: women, perceived stress off the job, responsability for household chores, emotional support, number of children, neuroticism, age.

Core self-evaluations as a moderator for the effects of role overload and powerlessness on ill-health / Margaretha Elizabeth Bonnet

Bonnet, Margaretha Elizabeth January 2007 (has links)
Employees in the Occupational Risk Division (ORD) of a large petrochemical company experience many difficult situations on a regular basis. This division of the company comprises the emergency services, the security and the occupational health divisions of the company. Even though every precaution is taken to ensure the safety of employees in the company, accidents and incidents do happen. The employees of the ORD are confronted with gruesome accidents, dangerous accident scenes where they have to enter when everyone else is evacuated, and security breeches where they may have to enter and resolve serious conflict situations. The possibility that their work climate may contributed to their mental health status is suggested. It is suspected that the stress of the job affects the mental health of the employees of the OCD, and ways need to be found to reduce these effects. The objective of this research was to determine the relationship between core self-evaluations, role overload, powerlessness and health indicators of employees in the ORD of a large petro-chemical company and to determine whether core self-evaluations act as a moderator in the relationship between role overload and powerlessness on the one hand and health indicators on the other hand. A cross-sectional design was used. The sample consisted of 299 employees from the Occupational Risk Division of the organization. Age, gender and level of education were included as control variables. A comprehensive survey containing the measuring instruments was administrated. Descriptive statistics and inferential statistics were used to analyse the data. Results obtained indicated that some of the scales were not reliable. Powerlessness was dropped from the analysis and qualitative and quantitative role overload were collapsed into a total overload measure. The results showed that a negative relationship exists between role overload and core self-evaluations. A positive relationship exists between role overload and neuroticism, poor health and depression. Self-esteem, self-efficacy and locus of control are negatively related to neuroticism and health, and neuroticism is positively related to poor health. Depression was predicted by experiences of overload, levels of self-efficacy, locus of control and negative affect (Neuroticism). General health was predicted by experiences of overload, locus of control, neuroticism and the interaction between overload and self-esteem. None of the scales predict medication use to a significant degree. Results further indicated that only self-esteem acts as a moderator in the relationship between role overload and general health, but none of the variables of core self-evaluations act as a moderator between role overload and depression or between role overload and the use of medication. By way of conclusion, recommendations for future research were made. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2008.

Adolescents with Depression Grown up : Education, Intimate Relationships, Mental Health, and Personality

Jonsson, Ulf January 2010 (has links)
Unipolar depression, estimated to be the leading contributor to burden of disease in middle- and high-income countries, often has an onset in adolescence. The disorder is associated with substantial role impairment and is highly recurrent. This raises questions about both subsequent mental health and social outcome. In order to shed light on this, a community sample of adolescents with depression and non-depressed peers was followed-up after 15 years. In 1991-93, first-year students in upper secondary school (age 16-17) in the town of Uppsala, Sweden, were screened for depression. Adolescents with positive screening and selected peers with negative screening (n=631 in total) were assessed regarding mental health, social situation, and personality. At around age 31, the participants were followed-up in both national registers (n=609) and personal interviews (n=409). Outcome regarding social factors, mental health, and personality was assessed. At follow-up, the former depressed adolescents had completed higher education to a lesser extent than the former non-depressed adolescents. The females with adolescent depression were also at increased risk of subsequent abortion, divorce, single parenthood, and partner violence. Characteristics associated with depression in adolescence (such as poor school performance and disruptive disorders) seemed to contribute to the poor outcome in the social domain. Regarding adult mental health, long-term depression in adolescence was associated with a particularly poor outcome. Compared to adolescents with shorter episodes of depression, those with long-term depression were more likely to report recurrent depression, suicidal ideation, and a range of other mental disorders in adulthood. Measures of personality traits related to neuroticism (a tendency towards negative emotionality) were elevated during ongoing depression and anxiety disorders, but were normalized with remission. However, repeated depressive episodes seemed to leave the individual more vulnerable to stress. It is now important to assess if early treatment can alter the poor outcome depicted in this thesis. Since social adversity, educational difficulties, and interpersonal problems accompany the depressive disorder from adolescence onward, it should also be investigated if interventions aimed at such contextual factors can prevent recurrence and improve quality of life.

Personality and Work-Family Conflict: The Mediational Role of Coping Styles

Bryant, Rebecca H 13 March 2009 (has links)
Although an extensive body of literature exists on the consequences of work-family conflict (WFC), comparatively little research has examined the construct's antecedents. Research on two sets of antecedent variables, personality and coping style, is particularly scarce. Thus, the present study expands the literature by examining four personality variables (conscientiousness, extraversion, neuroticism, and locus of control) and five coping styles (problem solving, support seeking, positive cognitive restructuring, rumination, and escape) in relation to work-interference-with-family (WIF) and family-interference-with-work (FIW) conflict. Additionally, coping style, which was assessed separately for managing work stressors and for managing family stressors, was examined as a potential mediator between personality and both directions of WFC. Two hundred and four participants, recruited from a snowball approach, completed surveys. Additionally, significant others provided ratings of conscientiousness, extraversion, and neuroticism. Of the four personality variables, only neuroticism related to WIF and FIW. Furthermore, among the hypothesized relationships between coping and WFC, only rumination and escape for work stressors related to WIF, though several cross-domain relationships were observed. Overall, the present study found little support for coping as a mediator between personality and WFC, though there was some evidence that rumination mediated the relationship between neuroticism and WIF. As a supplementary analysis, coping was examined as a moderator between personality and WFC. Theoretical and practical implications, as well as future directions, are discussed.

Personality Predictors of Relationship Satisfaction among Engaged and Married Couples: An Analysis of Actor and Partner Effects

Mead, Nicole L. 08 July 2005 (has links) (PDF)
With a sample of 3,436 engaged and married couples, this study explores the prediction of relationship satisfaction using the personality traits of neuroticism, depression, kindness, impulsivity, flexibility, self-esteem, and extraversion while utilizing controls for non-independent couple data in structural equation modeling. Both actor effects (the impact of an individual's personality on his or her own satisfaction) and partner effects (the impact of the partner's personality on satisfaction) are examined, including comparisons of the relative strength of each for males and females. A comparison is also made of engaged and married couples to determine if relationship status acts as a moderator. A separate model is estimated for each personality trait, and all the models show excellent fit statistics. Findings show significant, negative actor and partner effects for neuroticism, depression, and impulsivity, and significant, positive actor and partner effects for kindness, flexibility, and self-esteem among both engaged and married couples. Extraversion has some significant positive effects but is a weaker predictor. Actor effects are generally stronger than partner effects among the engaged couples in the sample, however among married couples the actor and partner effects are more often of equal magnitude. Many paths differ significantly between engaged and married couples, and in each case the paths are stronger among married couples. These findings support the idea that a variety of personality traits are important predictors of satisfaction, and that both actor and partner effects need to be considered. Findings also give evidence that relationship status acts as a moderator, indicating that personality may be a stronger predictor of satisfaction among married couples than engaged couples. With some traits, an engaged individual's own personality may be a more powerful predictor of his or her satisfaction than the partner's personality, while both spouse's traits may be equally predictive of a married individual's satisfaction.

The Relationship of Adult Attachment Dimensions and Neuroticism to Relationship Self-Regulation

Roundy, Garret Tyler 09 December 2011 (has links) (PDF)
Self-regulation in the context of a relationship, described as relationship "work," is a powerful predictor of relationship satisfaction. Identifying individual characteristics that predict the practice of relationship self-regulation (RSR) can inform clinical and couple relationship education interventions. Anxious and avoidant attachment have been linked to shortcomings in self-regulation in various contexts, and were hypothesized to be negatively associated to individual practice of RSR; neuroticism, a personality trait characterized by negative emotionality, was also hypothesized to be negatively related to RSR. Neuroticism was also tested as a moderator of the relationship between attachment and RSR. Data from first-married men (589) and women (912) taking the RELATE online questionnaire was used in correlational and OLS multiple regression analyses to test hypotheses and a research question. Bi-variate correlations for all predictor variables and RSR were negative and statistically significant for women and men. Regression analyses echoed those associations. Moderated multiple regression analyses testing a moderator effect of neuroticism were significant for anxious attachment and RSR, but not for avoidant attachment. Results are interpreted as support for the theoretical model tested.

Assessing Validity and Bias of Within- Person Variability in Affect and Personality

Anvari, Farid, Rensing, Noëlle Z., Kalokerinos, Elise K., Lucas, Richard E., Schneider, Iris K. 21 August 2024 (has links)
Within-person variability in affect (e.g., Neuroticism) and personality have been linked to well-being. These are measured either by asking people to report how variable they are or to give multiple reports on the construct and calculating a within-person standard deviation adjusted for confounding by the person-level mean. The two measures are weakly correlated with one another and the links of variability with well-being depend on which measure researchers use. Recent research suggests that people’s repeated ratings may be biased by response styles. In a 7-day study (N = 399) with up to five measurements per day, we confirmed that the measures of variability lacked sufficient convergent validity to be used interchangeably. We found only 1 significant correlation (of 10) between variability in repeated ratings of affect or personality and variability in repeated ratings of a theoretically unrelated construct (i.e., features of images). There was very little evidence supporting the response styles hypothesis.
