Les facteurs psychologiques de performance au hockey selon les gardiens de but et leurs entraîneurs

Cette étude exploratoire vise essentiellement à identifier les principaux facteurs psychologiques des gardiens de but au hockey ayant connu du succès. Plus précisément, cette étude nous a permis d’approfondir le sujet à l’aide d’entrevues individuelles semi-dirigées menées auprès de sept gardiens de but et huit entraîneurs des gardiens de but issus de la Ligue de hockey junior majeur du Québec (LHJMQ). Nous avons ensuite comparé les réponses de ces deux groupes d’experts dans le domaine afin de dresser un portrait précis de l’aspect mental entourant cette position au hockey. Nos résultats démontrent que les mêmes facteurs psychologiques majeurs ressortent du discours des gardiens de but et de celui de leurs entraîneurs. Il a ainsi été possible d’identifier neuf attributs psychologiques prédominants provenant des discours de chacune des parties. Plus précisément, ces neuf facteurs psychologiques reliés à l’atteinte d’une performance athlétique hors pair seraient les traits de personnalité, la résilience, le niveau de confiance, la passion, l’état d’esprit optimal, l’éthique au quotidien, un niveau de concentration optimal, la relativisation des événements et le contrôle des émotions. De manière générale, nos résultats vont dans le même sens que les conclusions tirées des autres études sur les différents aspects mentaux des athlètes de niveau élite. Toutefois, on observe un manque de données scientifiques en ce qui a trait à la psychologie du sport chez les gardiens de but au hockey. Cette étude constitue donc un premier développement dans l’identification des atouts psychologiques influençant la performance des gardiens de but au hockey.

"Escala de ambiguidade"

O objetivo deste trabalho foi a construção de um instrumento para medir o nível de ambiguidade expresso pelos indivíduos em situações simples do cotidiano. Definiu-se como nível de ambiguidade, a capacidade do indivíduo para criar ambiguidade diante de determinadas situações sociais. Este trabalho vem como consequência da tese de doutorado "Anomia e Desorganização: estudo psicológico em contexto brasileiro", elaborada em 1981 e cujos resultados, confrontados com a realidade cotidiana, fizeram ressaltar o modelo ambíguo característico de nossa sociedade, que se afigura sob a forma de variadas contradições nas atitudes dos indivíduos. A ambiguidade parece ser encontrada no sistema como resultante da interpretação que o indivíduo dá a padrões, leis, normas e valores ambíguos ou ainda como consequência da própria violação ou desinformação a respeito das regras, das constantes reformulações, da desconfiança, da adaptação social de um modo geral. O enfoque teórico se baseou fundamentalmente em teorias antropológicas e sociais que propõem a realidade como algo construído pelo indivíduo e onde apareceria o comportamento ambíguo como resultante da interrelação entre o indivíduo e o meio social no qual ele se desenvolve. Para a fundamentação da escala foram isolados dois fatores a saber: (1) a ambiguidade como fator social e (2) a ambiguidade como fator psicológico.

Factors affecting the symptom burden in chronic heart failure

Background. Heart failure (HF) is a health problem of epidemic proportions and a clinical syndrome that leads to progressively severe symptoms, which contribute significantly to the burden of the disease. Several factors may affect the symptom burden of patients with HF, including physiological, psychological, and spiritual factors. This study was designed to examine the inter-relationship of physiological, psychological, and spiritual factors affecting symptoms for patients with HF. ^ Objectives. The aims of this study were to examine symptom burden of heart failure patients related to: (1) the physiological factor of brain natriuretic peptide (BNP); (2) the psychological factor of depression; (3) the spiritual factors of self transcendence and purpose in life; and (4) combined effects of physiological, psychological and spiritual factors. One additional aim was to describe symptom intensity related to symptom burden. ^ Methods. A cross-sectional non-experimental correlational design was used to examine factors affecting symptom burden in 105 patients with HF from a southwestern medical center outpatient heart failure clinic. Both men and women were included; average age was 56.6 (SD = 16.86). All measures except BNP were obtained by patient self-report. ^ Results. The mean number of symptoms present was 8.17 (SD = 3.34) with the three most common symptoms being shortness of breath on exertion, fatigue, and weakness. The mean symptom intensity was 365.66 (SD = 199.50) on a summative scale of visual analogue reports for 13 symptoms. The mean BNP level was 292.64 pg/ml (SD = 57 1.11). The prevalence rate for depression was 43.6% with a mean score of 3.48 (SD = 2.75) on the Center for Epidemiological Studies - Depression scale (CES-D 10) scale. In a multivariate analysis, depression was the only significant predictor of symptom burden (r = .474; P < .001), accounting for 18% of the variance. Spirituality had an interaction effect with depression (P ≤ .001), serving as a moderator between depression and symptom burden. ^ Conclusion. HF is a chronic and progressive syndrome characterized by severe symptoms, hospitalizations and disability. Depression is significantly related to symptom burden and this relationship is moderated by spirituality. ^

Liderazgo y autoeficacia en el comportamiento organizacional positivo

El objetivo que tiene este proyecto es revisar los conceptos básicos acerca de las relaciones que crean los líderes con sus colaboradores dentro de las organizaciones, dichas relaciones y vínculos pueden afectar positiva o negativamente el desempeño de sus actividades diarias dentro de una organización. Para darle inicio a la investigación se estudió como primer paso el concepto de liderazgo transformacional, capital psicológico y que componentes hacían parte de este factor. El desarrollo de la investigación se enfatizó entre el liderazgo transformacional y la autoeficacia ya que son factores claves dentro del desarrollo de las actividades organizacionales debido a que afectan claramente el capital humano de las compañías y están directamente relacionados con el crecimiento de las mismas, lo que nos llevó a preguntarnos ¿qué relación tendrá el liderazgo transformacional y la autoeficacia en la productividad de las empresas? Es aquí donde radica la importancia de esta investigación ya que el cambio de pensamiento de las organizaciones hacia un liderazgo transformacional podría lograr una maximización del desempeño del personal de trabajo en relación al objetivo de la compañía. Como conclusión llegamos a que efectivamente hay un efecto positivo en los individuos que desarrollan un capital psicológico específicamente en el factor de autoeficacia para lograr un desempeño destacable, productivo y eficiente dentro de las organizaciones.

Impact of positively- versus negatively-worded items on the factor structure of three psychological measures: W-BQ22, W-BQ12 & SF-36

Background: The 22-item Well-being Questionnaire (W-BQ22) (Bradley, 1994) includes Anxiety, Depression, Energy and Positive Well-being subscales. However, the constructs of anxiety and depression could not be easily distinguished from each other. Consequently, the W-BQ12 was designed to include just three subscales, Negative Well-being (including only negatively-worded anxiety and depression items), Energy (2 positively- and 2 negativelyworded items) and Positive Well-being (all positively-worded items). The SF-36 (Ware & Sherbourne, 1983), a widely used health status measure, includes a 4-item vitality subscale (2 positively- and 2 negatively-worded items) and a 5-item mental health scale (2 positively worded and 3 negatively-worded items).

Method: Factor structures of W-BQ22, W-BQ12 and SF-36 were compared using data from 789 outpatients with diabetes.

Results: W-BQ22 factor analysis showed negatively-worded anxiety and depression items loading together, while positively-worded depression items loaded with positive well-being items and separately from positively-worded anxiety items. W-BQ12 loaded as intended on 3 factors, with negatively-worded anxiety and depression items loading together on one factor: negative well-being. The four energy items (2 positively- and 2 negatively-worded) loaded together (factor 3) and the four positive well-being items loaded together (factor 1). Unforced factor analysis of the SF-36 produced 5 factors and split the mental health and vitality items into two components, which could only be defined in terms of positive and negative wording. A forced 8-factor solution produced similar results, with the mental health and vitality items being split into two components according to their positive or negative wording. A forced 2-factor solution brought mental health/vitality items together, separate from physical health items.

Conclusion: The previously unrecognised influence of positive and negative wording on factor structure is clearly shown here to be of importance in conceptualising and designing measures of psychological well-being to be used with people with diabetes and may be of relevance for other populations.

Effects of aspirin and propranolol on the acute psychological stress response in factor VIII coagulant activity: a randomized, double-blind, placebo-controlled experimental study

Activity of clotting factor VIII has been shown to acutely increase with sympathetic nervous system stimulation. We investigated whether aspirin and propranolol affect the responsiveness of plasma clotting factor VIII activity levels to acute psychosocial stress. We randomized 54 healthy subjects double-blind to 5-day treatment with a single daily oral dosage of either 100 mg aspirin plus 80 mg propranolol combined, 100 mg of aspirin, 80 mg of propranolol, or placebo medication. Thereafter, subjects underwent a 13-min standardized psychosocial stressor. Plasma levels of clotting factor VIII activity were determined immediately before, immediately after, 45 min and 105 min after stress. Controlling for demographic, metabolic, and life style factors repeated measures analysis of covariance showed that the change in clotting factor VIII activity from prestress to 105 min poststress differed between medication groups (P = 0.023; partial eta = 0.132). The clotting factor VIII activity level decreased from prestress to immediately poststress in the aspirin/propranolol group relative to the placebo group (P = 0.048) and the aspirin group (P < 0.06). Between 45 min and 105 min poststress, clotting factor VIII levels increased in the aspirin/propranolol group relative to the placebo group (P = 0.007) and the aspirin group (P = 0.039). The stress response in clotting factor VIII activity levels was not significantly different between the aspirin/propranolol group and the propranolol group. Propranolol in combination with aspirin diminished the acute response in clotting factor VIII activity to psychosocial stress compared with placebo medication and aspirin alone. The effect of single aspirin on the acute clotting factor VIII stress response was indistinguishable from a placebo effect.

Confirmatory factor analysis of the Way of Coping Checklist-Revised (WCCL-R) in the Asian context

Industrial employment growth has been one of the most dynamic areas of expansion in Asia; however, current trends in industrialised working environments have resulted in greater employee stress. Despite research showing that cultural values affect the way people cope with stress, there is a dearth of psychometrically established tools for use in non-Western countries to measure these constructs. Studies of the "Way of Coping Checklist-Revised" (WCCL-R) in the West suggest that the WCCL-R has good psychometric properties, but its applicability in the East is still understudied. A confirmatory factor analysis (CFA) is used to validate the WCCL-R constructs in an Asian population. This study used 1,314 participants from Indonesia, Sri Lanka, Singapore, and Thailand. An initial exploratory factor analysis revealed that original structures were not confirmed; however, a subsequent EFA and CFA showed that a 38-item, five-factor structure model was confirmed. The revised WCCL-R in the Asian sample was also found to have good reliability and sound construct and concurrent validity. The 38-item structure of the WCCL-R has considerable potential in future occupational stress-related research in Asian countries.

Psychological predictors of young adults' use of social networking sites

Young people are increasingly using social networking sites (SNSs), like Myspace and Facebook, to engage with others. The use of SNSs can have both positive and negative effects on the individual; however, few research studies identify the types of people who frequent these Internet sites. This study sought to predict young adults’ use of SNSs and addictive tendency towards the use of SNSs from their personality characteristics and levels of self-esteem. University students (N = 201), aged 17 to 24 years, reported their use of SNSs and addictive tendencies for SNSs use, and completed the NEO Five-Factor Personality Inventory 1 and the Coopersmith Self-Esteem Inventory.2 Multiple regression analyses revealed that, as a group, the personality and self-esteem factors significantly predicted both level of SNS use and addictive tendency but did not explain a large amount of variance in either outcome measure. The findings indicated that extraverted and unconscientious individuals reported higher levels of both SNS use and addictive tendencies. Future research should attempt to identify which other psychosocial characteristics explain young people’s level of use and propensity for addictive tendencies for these popular Internet sites.

Examination of the latent structure of the psychological sense of school membership scale

Despite its widespread use, there has been limited examination of the underlying factor structure of the Psychological Sense of School Membership (PSSM) scale. The current study examined the psychometric properties of the PSSM to refine its utility for researchers and practitioners using a sample of 504 Australian high school students. Results from exploratory and confirmatory factor analyses indicated that the PSSM is a multidimensional instrument. Factor analysis procedures identified three factors representing related aspects of students’ perceptions of their school membership: caring relationships, acceptance, and rejection

The Australian Grey Nomads : are they who we think they are? Enhancing formative research through the quantitative assessment of psychological constructs

Issue addressed: Measures of 'social identity' and 'psychological sense of community' were included within a broader formative research inquiry to gain insight into the identity characteristics and level of connectedness among older recreational road travellers (commonly known as Grey Nomads). The research sought to gain insights on how best to reach or speak to this growing driver cohort. ----- ----- Method: Participants included 631 older recreational road travellers ranging in age from 50 years to over 80 years. Data were obtained through three scales which were incorporated into a larger formative research survey; an identity hierarchy, the Three Factor Model of Social Identity and the Sense of Community Index. ----- ----- Results: Older recreational road travellers see themselves principally as couples, with social group identity being secondary. Although many identified to some degree with the Grey Nomad identity, when asked to self categorise as either members of the Broad Network of Recreational Vehicle Travellers or as Grey Nomads, the majority categorised themselves as the former. Those identifying as Grey Nomads, however, reported significantly higher levels of 'social identification' and 'sense of community'. ----- ----- Conclusion: The Grey Nomad identity may not be the best identity at which to target road safety messages for this cohort. Targeting travelling 'couples' may be more efficacious. Using the 'Grey Nomad' identity is likely to reap at least some success, however, given that many identified to some degree with this group identity. Those identifying as Grey Nomads may be more open to community participation or behaviour change given their significantly higher levels of 'social identity' and 'sense of community'.
