The present study aimed at determining whether a significant relationship exists between procrastination, delay of gratification, and job satisfaction, with work‐related stress as an intervening variable among high school teachers. The sample consisted of 150 high school teachers from Karachi, Pakistan. The analysis showed a negative correlation between procrastination and job satisfaction, and a positive correlation between delay of gratification and job satisfaction. Also, procrastination and delay of gratification were significant predictors of work‐related stress, and work‐related stress was also a significant predictor of job satisfaction. In conclusion, when the teachers are not procrastinating on their job and score high on delay of gratification they will be more satisfied with their job and feel less stressed.  相似文献

Although studies have examined the effects of interventions focused on preterm infants, few studies have examined the effects on maternal distress (anxiety, depressive symptoms, post-traumatic stress symptoms, parenting stress) or parenting. This study examined the effects of the auditory–tactile–visual–vestibular (ATVV) intervention and kangaroo care (KC) on maternal distress and the mother–infant relationship compared to an attention control group.240 mothers from four hospitals were randomly assigned to the three groups. Maternal characteristics in the three groups were similar: 64.1% of ATVV mothers, 64.2% of KC mothers, and 76.5% of control mothers were African American; maternal age averaged 26.3 years for ATVV mothers, 28.1 for KC mothers, and 26.6 for control mothers; and years of education averaged 13.6 for ATVV and KC mothers, and 13.1 for control mothers. Mothers only differed on parity: 68.4% of ATVV and 54.7% of KC mothers were first-time mothers as compared to 43.6% of control mothers. Their infants had a similar mean gestational ages (27.0 weeks for ATVV, 27.2 for KC, and 27.4 for control) and mean birthweights (993 g for ATVV, 1022 for KC, and 1023 for control).Mothers completed questionnaires during hospitalization, and at 2, 6 and 12 months corrected age on demographic characteristics, depressive symptoms, state anxiety, post-traumatic stress symptoms, parenting stress, worry about child health, and child vulnerability (only at 12 months). At 2 and 6 months, 45-min videotapes of mother–infant interactions were made, and the HOME Inventory was scored. Behaviors coded from the videotapes and a HOME subscale were combined into five interactive dimensions: maternal positive involvement and developmental stimulation and child social behaviors, developmental maturity, and irritability.Intervention effects were examined using general linear mixed models controlling for parity and recruitment site. The groups did not differ on any maternal distress variable. Kangaroo care mothers showed a more rapid decline in worry than the other mothers. The only interactive dimensions that differed between the groups were child social behaviors and developmental maturity, which were both higher for kangaroo care infants. Change over time in several individual infant behaviors was affected by the interventions. When mothers reported on the interventions they performed, regardless of group assignment, massage (any form including ATVV) was associated with a more rapid decline in depressive symptoms and higher HOME scores. Performing either intervention was associated with lower parenting stress. These findings suggest that as short-term interventions, KC and ATVV have important effects on mothers and their preterm infants, especially in the first half of the first year.  相似文献

This research examined the extent to which the Big Five personality factors mediated the relationship between age and time-of-day preference. A sample of 491 Americans (Mage = 32 yrs) completed the 240-item NEO-PI-R, the 19-item Horne and Östberg’s (1976) Morningness–Eveningness Questionnaire (MEQ), and provided demographic information. As demonstrated in previous research, correlations revealed that older people expressed a stronger morning preference. More importantly, using bootstrapping procedures, it was found that the Big Five factor of conscientiousness attenuated the relationship between age and time-of-day preference. These findings indicate that conscientiousness plays a significant role in the relationship between age and time-of-day preference.  相似文献

To create customer-oriented organizations, managers are often asked to promote a values-based vision. Yet, many managers struggle with transferring their values to employees making strategic value changes difficult. Despite this challenge, research has yet to demonstrate how managers effectively align values within the sales force, or the impact alignment has on job outcomes. Therefore, we develop and empirically test a conceptual framework to examine the role of transformational leadership in aligning salesperson customer orientation (CO) values. We find that transformational leadership is a strong mechanism in creating perceived value congruence, yet may have a surprising dark side. Results suggest that transformational managers achieve congruence by raising or, contrary to conventional wisdom, lowering salesperson CO values to meet the perceived values of the manager. Response surface modelling results support the importance of perceived manager values. Customer-oriented salespeople have higher job satisfaction and sales performance when they perceive their manager to also have high CO. When values are misaligned, job satisfaction increases more for low CO salespeople as perceptions of manager CO increase. Exploratory findings show that performance was higher under situations of perfect alignment but also under severe misalignment suggesting that values generate performance under complementary or supplementary conditions.  相似文献

Neuroticism is a predictor of many health problems. To study the determinants of within‐subject change in neuroticism, three hypotheses were tested: (i) subjects who experienced stressful life events (SLEs) show an increase in neuroticism; (ii) high baseline neuroticism moderated this effect; and (iii) recent SLEs had a greater impact on neuroticism than distant SLEs. Data came from the Finnish Twin Cohort. Neuroticism data were collected in 1975 and 1981 and SLEs data in 1981 (n = 21 085). By entering baseline neuroticism as a predictor for neuroticism at follow‐up, the outcome measure was change in neuroticism. Changes in neuroticism were predicted from SLE indices or their interaction with baseline neuroticism. Timing of SLEs was taken into account by distinguishing recent from distant SLEs. To control for confounding by shared genes and environments, both within‐twin pair and between‐twin pair effects were tested for monozygotic and dizygotic twin pairs separately. Neuroticism's six‐year stability was high (r = .58, p < .001). Exposure to SLEs modestly increased neuroticism (βs > .55, ps < .001), unconfounded by shared genes. This effect was not moderated by high baseline neuroticism. Recent SLEs (.09 < βs < .15) had more impact than distant SLEs (.03 < βs < .11; ps < .01). In conclusion, the findings strongly supported a model of environmentally driven SLEs causing dynamic fluctuations around a person's set point of neuroticism.

Diagnostic work is the reflexive work of figuring out what issues are at stake and determining the scope for action. This work is not generally accommodated by evidence-based guidelines, which generally promote a uniform, predefined approach to solving healthcare problems that risk narrowing the opportunities for diagnostic work in healthcare practice. Consequently, guidelines are often criticised as too general to solve situated, individual healthcare problems and gaps between guidelines and their implementation are often reported. The Netherlands has developed a guideline for problem behaviour in elderly care, explicitly designed for diagnostic work, thus stimulating a situated approach. Relational problem behaviour is highly embedded in its context. The guideline stimulates diagnostic work, which helps to unravel problem behaviour and is opening alternatives in elderly care. Diagnostic work does not transfer guideline development problems to healthcare practice, but simply structures the decision-making process without giving a predefined answer. Diagnostic work is thus important to consider in order to avoid a gap between guideline development and implementation.  相似文献

This study was designed to adapt and to assess the reliability and factor structure of an Italian translation of the full and short form of the Posttraumatic Growth Inventory. A sample of 1,244 Italian adults who had experienced a range of adverse life events participated in this study. Five models of the underlying structure of the Posttraumatic Growth Inventory were tested via confirmatory factor analyses. Analyses of both the short and full form of the PTGI provided support for the original correlated five-factor structure. Multigroup confirmatory factor analysis supported the invariance of the Posttraumatic Growth Inventory across gender.  相似文献

Body dysmorphic disorder falls under the category of obsessive–compulsive and related disorders, yet research has suggested it may also be highly associated with social anxiety disorder. The current study examined body image variables among 68 outpatients with primary obsessive–compulsive disorder (OCD; n = 22), social anxiety disorder (SAD; n = 25), and panic disorder (PD; n = 21). Participants filled out self-report measures of body image disturbance, attitudes toward one's appearance, and anxiety. Body image disturbance and attitudes toward appearance did not significantly differ between the groups. However, SAD symptoms predicted body image disturbance, Appearance Evaluation and Body Areas Satisfaction, and OCD symptoms predicted Appearance Orientation. These findings suggest that SAD and OCD may be associated with different facets of body image. Implications for the treatment of anxiety disorders and for future research are discussed.  相似文献

Are helping professionals who have experienced the same types of struggles as their clients more engaged at work? In the current investigation, we examine this question in samples of police detectives (with and without a history of violent victimization) and mental health workers (with and without a history of mental illness). Our results indicate that police detectives who have experienced violent victimization and mental health professionals who have experienced the same mental illness as their clients do indeed exhibit greater work engagement than their colleagues who lack these parallel life experiences. The link between a professional’s firsthand experience of his/her client’s hardships and work engagement appears to be partially explained by higher levels of grit among police detectives and by a greater sense of life-narrative continuity among mental health professionals.  相似文献
