Qualitative differences in psychiatric symptoms between high risk groups assessed on a screening test (GHQ-30)

Scores on five subscales derived from the GHQ-30 have been examined in various groups at risk for psychiatric disorder, to determine whether different patterns of symptoms are found. The subscales are based on a factor analysis of a population sample of over 6,000 adults (Huppert et al. 1989) which identified five robust factors corresponding to symptoms of anxiety, feelings of incompetence, depression, difficulty in coping and social dysfunction. Previous studies have identified certain groups of people who are vulnerable to mental illness and are therefore likely to obtain a high score on the GHQ. These include unemployed men, single women with dependent children, and elderly people in poor health. The results show marked differences in symptom patterns among these three at-risk groups. For example, while scores on anxiety and depression subscales were significantly raised in most at-risk groups, young unemployed men did not show significant anxiety whereas elderly men in poor health did not show significant depressive symptoms. However both these groups showed difficulty in coping, unlike older unemployed men or elderly women in poor health. Single women with dependent children reported the highest rate of psychiatric symptoms, particularly anxiety and depression, but had difficulty in coping only if they were also employed. These findings suggest that this method of analysing data from the GHQ-30 has potential value in yielding qualitative as well as quantitative information about psychiatric symptoms.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41738/1/127_2004_Article_BF00789216.pd

Psychological and Environmental Correlates of Well-being Among Undergraduate University Students

This study explored whether the university environment provides similar well-being enhancing elements to those that have been found in the workplace and school contexts. Whether psychological inflexibility accounts for well-being over and above personality and environmental influences was also explored. A representative sample of 163 undergraduate university students in an Australian university completed an online survey measuring the key constructs. Environmental influences assessed included financial resources, physical security, opportunity to use new skills, externally generated goals, variety, environmental clarity, interpersonal contact, and valued social position. Hierarchical multiple linear regression analyses were then conducted to test for predictors of three domains of subjective well-being: positive affect, negative affect, and life satisfaction. The results suggested that university context contributes significantly to undergraduate students’ well-being by providing a valued social role, externally generated goals, and variety. Students’ perception of their physical security was also an important influence on their well-being. These results are consistent with the literature on well-being and employment. Neuroticism significantly predicted negative affect, while psychological inflexibility accounted for unique variance in life satisfaction and negative affect even when personality and environmental influences were taken into account. The implications of these findings for enhancing undergraduate university students’ well-being are discussed
