Psychological stress-factors and concentrations of immunoglobulins and complement components in humans

Relationships between two types of occupational stress, one chronic and one acute, and plasma immunoglobulin and complement components were measured. The first group comprised female primary school teachers ( N =40) subjected to long-lasting work stress. The second group comprised male merchant navy students ( N =38) subjected to a series of short-lasting fear-inducing 20 meter drops in a life boat specially built for rescue operations from oil platforms. Significant correlations were found between personality factors, immunoglobulins and complement components in the teacher group, but not amongst the merchant navy students. For the teachers, personality traits correlated negatively with concentrations of IgA and IgG. IgM concentrations correlated with the more immediate work-related problems reported by the teachers. In a multiple regression analysis, psychological factors explained between 32% (IgM) and 15% (IgG) of the interindividual variance, when sex, age and job seniority and employment factors were controlled for. Psychological factors may therefore, at least on longlasting occupational stress groups, correlate with immune processes. The data support the concept of the importance for psychological factors in immunological function.     

Psychiatric labeling and social perception

The present study explores the effects of three types of psychiatric labeling on attribution of causality and impression formation. It was found that observers tended to be more person-oriented in their attributions when explaining an accident of a person being labeled formerly mentally ill and formerly psychiatrically hospitalized, as compared to a non-psychiatric control label. However, no such tendency towards person-orientation in causal attribution was found for a problems-of-living label. These effects were found to be independent of variation in amount of neutral context information about the person being labeled. The effect of labeling on impression formation was found to be inconclusive, and reasons for this are discussed. Context information was found to affect impression formation in that the person was evaluated more positively. No sex differences in attribution of causality and impression formation was found.     

Self-Handicapping Related to Task and Performance-Approach and Avoidance Goals in Physical Education

This study examined the relationships between achievement goals (task, performance-approach, performance-avoid) and self-handicapping in the area of secondary school physical education. The sample consisted of 273 ninth grade students (125 male, 148 female). Regression analysis revealed that a task goal and a performance-approach goal were negatively related to self-handicapping, whereas a performance-avoidance goal related positively to self-handicapping. Altogether, 14% of the variance in self-handicapping was explained by the three achievement goals. Analyses of covariance further revealed that a task goal influenced the way performance-approach and performance-avoidance goal related to self-handicapping. Specifically, to some extent a high task goal seems to moderate the aversive effects on self-handicapping of holding either a performance-approach goal or a performance-avoidance goal. Taken together, analyses indicate that, a performance-avoidance goal more strongly deserve being labeled the motivationally “bad guy” in terms of generating self-handicapping. In terms of self-handicapping a performance-approach goal, in contrast, seems more readily characterized as a motivationally double-edged sword.     

Predicting 13-year-olds' drinking using parents' self-reported alcohol use and restrictiveness compared with offspring's perception

This study examined whether offspring's perception of parental frequency of alcohol use and restrictiveness towards offspring's alcohol use could be used as a substitute for parental self-reports. Offspring's perception were compared with parents' self-reported alcohol use and restrictiveness in ability to predict offspring's own alcohol use. Respondents were 924 offspring, 642 fathers and 729 mothers. Correlations between fathers' and mothers' self-reported frequency of drinking alcohol and offspring's reports of parental frequency of drinking alcohol ranged from 0.55 to 0.70. Fathers' and mothers' self-reported alccohl use and restrictiveness explained less than two per cent of the variance in their offspring's alcohol use in regression analyses, while offspring's perception of parental drinking frequency and restrictiveness exaplained about eight per cent of the variance in offspring's alcohol use. These results represent a challenge to studies of young adolescents which interpret offspring's reports of parents' alcohol use as a surrogate measure 'of parents' self-reported alcohol use.     

Age discrimination in the workplace: Validation of the Nordic Age Discrimination Scale (NADS)

Furunes, T. & Mykletun, R. J. (2010). Age discrimination in the workplace: Validation of the Nordic Age Discrimination Scale (NADS). Scandinavian Journal of Psychology, 51 , 23–30.
Due to population ageing, older workers will make up a larger proportion of the workforce. However, recent reports show an increase in perceived age discrimination among older employees. Previous research found that age discrimination may result in negative feelings, such as uselessness, powerlessness and lower self-esteem. This study develops and validates a scale for monitoring age discrimination in the workplace. The validation study draws on three datasets, from Norway, Sweden and Finland respectively. The study provides a psychometric contribution to the study of the behavioral component of ageism.
