Social cognitive predictors of academic adjustment and life satisfaction in Portuguese college students: A longitudinal analysis

A social cognitive model of well-being [Lent, R. W. (2004). Toward a unifying theoretical and practical perspective on well-being and psychosocial adjustment. Journal of Counseling Psychology, 51, 482--509.] was adapted to the context of academic adjustment and tested using a longitudinal design. Participants were 252 students at a university in northern Portugal. They completed measures of academic self-efficacy, environmental support, goal progress, and adjustment, along with global measures of positive affect and life satisfaction. Path analyses indicated that the model fit the data well overall. As expected, self-efficacy and environmental support were predictive of goal progress and academic adjustment, and the latter was predictive of students’ global life satisfaction. Self-efficacy and positive affect were found to be reciprocally related to one another. Contrary to expectations, goal progress did not contribute uniquely to the prediction of academic adjustment or life satisfaction. We consider directions for future research applying the social cognitive model to satisfaction in, and adjustment to, educational and work settings.     

Two tests of the social cognitive model of well-being in Portuguese college students

A social cognitive model of well-being (Lent & Brown, 2006, 2008) was tested in two studies (one cross-sectional, one longitudinal) with Portuguese college students. Participants in Study 1 (N = 366) completed measures of academic self-efficacy, environmental support, goal progress, academic satisfaction and stress, trait positive affect, and overall life satisfaction at a single assessment. Those in Study 2 (N = 158) took the same measures at each of two time points, 15 weeks apart. A modified version of the model improved the fit to the data in Study 1. Optimal fit in Study 2 was achieved with a bidirectional version that modeled reciprocal relations of positive affect to both self-efficacy and support. The predictors in both studies accounted for substantial portions of the variance in academic domain satisfaction, academic stress, and life satisfaction. Implications for future research on the social cognitive model in educational and work settings are considered.     

Modifications in basal and stress-induced hypothalamic AMP-activated protein kinase (AMPK) activity in rats chronically treated with an angiotensin II receptor blocker

5' adenosine monophosphate-activated protein kinase (AMPK) plays a prominent role as a metabolic stress sensor. The role of hypothalamic AMPK in response to restraint and surgical stress has not been previously investigated. It has been recently suggested that the renin-angiotensin system, in addition to its role in stress regulation, may play a significant role in regulating metabolic pathways including the regulation of the AMPK system. This study was thus aimed to evaluate the effects of candesartan, an angiotensin II AT1 receptor blocker drug, on hypothalamic AMPK activity under basal conditions and after restraint in conscious rats or after surgical stress under general anesthesia. Male Wistar rats were treated with 5 mg/kg/day candesartan in the drinking water for 2 weeks. The hypothalamic AMPK activity was determined under basal and stress conditions, using a kinase activity assay. Chronic administration of candesartan significantly increased hypothalamic AMPK activity. Hypothalamic AMPK activity was also increased by restraint stress whereas no change was observed during surgical stress under anesthesia. The high levels of hypothalamic AMPK activation observed in candesartan-treated rats were not changed by restraint stress but were reduced to control levels by anesthesia and surgery. In conclusion, chronic candesartan treatment and restraint stress in conscious rats stimulate the hypothalamic AMPK activity, whereas surgical stress under anesthesia inhibits pathways regulating the AMPK activity even in candesartan-treated rats.
