This paper seeks to examine transformational and transactional leadership, employees’ organizational citizenship behavior, employees’ job satisfaction and perceived organizational sup­port; which are employees' organizational citizenship behavior associations. In addition, this study explores the mediating role of employees’ job satisfaction and perceived organizational support in the relationship between transformational and transactional leadership styles and employees’ organizational citizenship behavior. The study was conducted at the University of Birjand, Iran, on a sample of 250 employees. This research follows a descriptive and correlational approach. Our findings show that transformational leadership and employees’ job satisfaction and perceived organizational support positively and significantly influence employees’ organizational citizen-ship behavior. Additionally, results revealed that employees’ job satisfaction mediates the asso­ciation between transformational and transactional leadership and employees’ organizational citizenship behavior. Moreover, employees perceived organizational support mediates the asso­ciation between transformational and transactional leadership and employees’ organizational citi­zenship behavior. Iranian organizations, especially universities, should invest in transformational leadership and job satisfaction, as well as in the selection of managers with transformational lead­ership styles and employees who are eager to work at the university, in order to enrich the organi­zational citizenship behavior of employees.

Background. Meaning in life is one of the psychological domains that is most severely affected in patients with life-threatening illnesses. The importance of meaning-making mandates the development of reliable tools to assess this construct. Steger’s Meaning in Life Questionnaire (MLQ) is one of the most valid and reliable instruments that determines the search for and presence of meaning in life. The present study was conducted to provide psychometric data on the MLQ in a sample of patients with life-threatening illnesses. Methods. The MLQ was completed by 301 patients (aged 20–80 years) diagnosed with life-threatening illnesses (cancer and multiple sclerosis) and referred to hospitals. Confirmatory factor analysis and Pearson’s correlation test were used to determine the construct validity of the questionnaire. Results. The confirmatory factor analysis supported the original two-factor model of the MLQ, comprised of the presence of meaning (five items) and search for meaning (five items). The responses to the MLQ did not differ by sociodemographic factors. Most importantly, contrary to previous findings, the correlation between the two subscales, i.e., search for meaning and presence of meaning, was significant and positive. Conclusion. The results showed that the MLQ is a valid and reliable measure for assessing meaning in life that can be applied in research on meaning in life among other patient populations.

Background Any loss or deviation in body function and structure is considered impairment, whereas limitations on activities are fundamental to the definition of disability. Although it seems intuitive that the two should be closely related, this might not be the case; there is some evidence that psychosocial factors are more important determinants of disability than are objective impairments. However, the degree to which this is the case has been incompletely explored.Questions/purposes The purpose of this study was to determine if disability (as measured by the Disabilities of the Arm, Shoulder and Hand [DASH] and the Michigan Hand Questionnaire [MHQ]) and pain intensity correlate with impairment (as measured by the American Medical Association [AMA] impairment guide). Secondary study questions addressed the effect of pain intensity and symptom of depression on predicting disability. Methods Impairment and disability were evaluated in a sample of 107 hand-injured patients a mean of 11 months after injury. Impairment rating was performed prospectively. From the patients who came for therapy, they were invited to fill out the questionnaire and evaluated for impairment rating. Response variables of DASH, MHQ, and visual analog scale pain intensity values were collected at the same setting. Other explanatory variables included demographic, injury-related, and psychological factors (symptoms of depression measured with the Beck Depression Inventory). Initial bivariate and multivariate analyses were performed to determine correlations of disability and pain to impairment rating and other exploratory variables.Each author certifies that he or she, or a member of his or her immediate family, has no funding or commercial associations (eg, consultancies, stock ownership, equity interest, patent/licensing arrangements, etc) that might pose a conflict of interest in connection with the submitted article.

Together with gender, it accounted for only 22% of the variability in DASH scores. Similarly, MHQ score correlated with impairment rating (r = À0.24, beta = À0.23, p \ 0.05). However, together with age, injured hand accounted for only 19% of the variability in MHQ scores. However, pain intensity did not correlate with impairment (r = À0.46, p [ 0.05). Interestingly...

Low-frequency stimulation (LFS) is a potential therapy utilized in patients who do not achieve satisfactory control of seizures with pharmacological treatments. Here, we investigated the interaction between anticonvulsant effects of LFS and phenobarbital (a commonly used medicine) on amygdala-kindled seizures in rats. Animals were kindled by electrical stimulation of basolateral amygdala in a rapid manner (12 stimulations/day). Fully kindled animals randomly received one of the three treatment choices: phenobarbital (1, 2, 3, 4 and 8 mg/kg; i.p.; 30 min before kindling stimulation), LFS (one or 4 packages contained 100 or 200 monophasic square wave pulses, 0.1-ms pulse duration at 1 Hz, immediately before kindling stimulation) or a combination of both (phenobarbital at 3 mg/kg and LFS). Phenobarbital alone at the doses of 1, 2 and 3 mg/kg had no significant effect on the main seizure parameters. LFS application always produced anticonvulsant effects unless applied with the pattern of one package of 100 pulses, which is considered as non-effective. All the seizure parameters were significantly reduced when phenobarbital (3 mg/kg) was administered prior to the application of the non-effective pattern of LFS. Phenobarbital (3 mg/kg) also increased the anticonvulsant actions of the effective LFS pattern. Our results provide an evidence of a positive cumulative anticonvulsant effect of LFS and phenobarbital, suggesting a potential combination therapy at sub-threshold dosages of phenobarbital and LFS to achieve a satisfactory clinical effect.

This study aimed to investigate construct validity and factor structure of the Persian Occupational Self-Assessment (OSA; Baron, Kielhofner, Iyenger, Goldhammer, & Wolenski, 2003 ) based on the model of human occupation (MOHO). Three hundred and thirty-six (179 male and 157 female) Iranian junior high students were measured using the OSA. The data were analyzed using a Confirmatory Factor Analysis (CFA) and the Rasch Rating Scale Model (RSM). In combination, the CFA and RSM results provided strong evidence for the construct validity of the Persian version. The CFA indicated that the hypothesized second-order model could explain the relationship of the OSA items to the latent variables of occupational competence and value for occupations. However, RSM item hierarchies did not replicate those found in previous international studies.

This study examined whether gender moderated the association between age cohort and the cognitive, reflective, and compassionate dimensions of wisdom, using an Iranian sample of 439 adults from three age cohorts: young (18-34), middle-aged (35-54), and older (55 and above). Results indicated that the interaction effect between gender and age cohort was significant for three-dimensional wisdom and all three wisdom dimensions. Compared with younger women and older men, older women tended to have less education and to score lower on the cognitive wisdom dimension, but they had similar average scores as older men on the compassionate wisdom dimension. Overall, the association between age and wisdom was only positive for men, due mainly to the positive relation between age and the reflective and compassionate wisdom dimensions for men after adjusting for education. The results are interpreted with reference to generation gaps, socialization of men versus women, and life experiences and opportunities.
