The role of personality and socio-economic status in the stress–illness relation: A longitudinal study

Although a wide variety of factors have been found to be related to health in some way, researchers on the subject of health generally fail to integrate findings of other research disciplines within their own line of research. This study has attempted to bring together two research disciplines: (a) research on personality and health, and (b) research on socio-economical differences in health. Personality factors as well as social class have been found to mediate the stress-illness relation. Based on empirical and theoretical considerations, we proposed a simple model for the occurrence and course of disease. The personality factors studied were neuroticism, locus of control, and self-esteem. Socio-economic status (SES) was represented by education level, occupation status, and income. Health was operationalized as the number of somatic diseases. The research questions were investigated (using t-tests andpath analysis) in a longitudinal set of data that were collected between 1970 and 1984 among 245 subjects in the normal population. Neuroticism appeared to be an important mediator of the stress-illness relation. Of the SES variables, occupation and education served as mediators; education was especially infuential on the course of disease. The role of neuroticism is discussed.     

Dynandcs in cancer caregiver's health over time: Gender-specific patterns and determinants

Abstract

This study exandned patterns and determinants of three dimensions of caregiver's health of newly diagnosed colorectal cancer patients, i.e. physical, mental and social functioning (N= 148). Physical functioning declined within a 6-month period in female caregivers, while no change was observed in male caregivers. For mental and social functioning, an improvement was observed in male and female caregivers. Change in physical functioning was associated with gender, age, income and initial level. Change in mental functioning was predicted by initial status and positive as well as negative caregiver experiences. Change in social functioning was mainly predicted by initial level and change in patient's dependency. Physical and mental functioning showed the least favorable patterns in female caregivers. The study shows that caregiving may lead to positive health consequences, and underlines the importance of making a distinction between male and female caregivers and of studying caregiver outcomes by using multidimensional assessments.     

Demographic,health-related and psychosocial predictors of changes in depressive symptoms and anxiety in late middle-aged and older persons with fall-related injuries

Research on anxiety and depression after fall-related injuries to the extremities and its pre-fall determinants is scarce. The present study sought to examine change between pre-fall and post-fall anxiety and depression and its (pre-fall) predictors. Data were obtained from 181 Dutch persons, aged 57 and older, who sustained fall-related injuries between 1993 and 1997. Demographic (e.g. socio-economic status), health-related (e.g. number of chronic conditions), and psychosocial (e.g. social support, neuroticism) factors were determined in 1993 (prior to the fall). Depressive symptoms and anxiety were determined prior to the fall, and two, five and twelve months after the fall. Taking into account pre-fall anxiety and depression, pre-fall neuroticism was the most consistent, independent predictor of adverse changes in anxiety and depression. Other factors, including severity of the fall and age were not related to changes in anxiety and depression. Our prospective findings may be interpreted as support for the importance of personality for mental health outcomes in persons who have sustained fall-related injuries.     

Neuroticism and Reactions to Social Comparison Information Among Cancer Patients

In an experimental study neuroticism was examined as a moderator of breast cancer patients' affective reactions to social comparison information about a fellow patient. Fifty-seven women with breast cancer completed Eysenck's Personality Questionnaire and received social comparison information about a fellow patient who was either doing better (upward condition) or worse (downward condition) than themselves. As expected, patients showed more positive reactions to upward comparison information than to downward comparison information. Moreover, neuroticism was related to responding more negatively and less positively to social comparison information. Although respondents high and low in neuroticism did not differ in their reactions to downward comparison information, low neuroticism was associated with more positive responding to upward comparison information.     

The role of pain behaviour and family caregiver responses in the link between pain catastrophising and pain intensity: A moderated mediation model

Objectives: This study investigated the mediating role of pain behaviours in the association between pain catastrophising and pain intensity and explored the moderating role of family caregivers’ responses to pain in the link between pain behaviours and pain intensity.

Methods: The sample consisted of 154 chronic pain patients and their family caregivers. Patients completed questionnaires regarding pain intensity, pain catastrophising, pain behaviours and their caregivers’ responses to their pain. Family caregivers reported their responses to the patients’ pain.

Results: Pain catastrophising was associated with pain intensity (r = 0.37) and pain behaviours partly mediated this association. The positive association between pain behaviours and pain intensity was significant only if patients reported that their family caregivers showed high levels of solicitous (effect = .49) and distracting responses (effect = .58), and if caregivers reported to show high levels of solicitous responses (effect = .51). No support was found for negative responses as a moderator neither based on patients’ perception of negative responses nor based on caregivers’ perception of negative responses.

Conclusions: The findings are in line with the idea that family caregivers’ solicitous and distracting responses convey to patients that their condition is serious, which may reinforce patients’ pain and pain behaviours, especially in those who catastrophise.     

Assessment of psychopathology in 2‐ to 5‐year‐olds: Applying the Infant–Toddler Social Emotional Assessment

The information provided by parents is indispensable for the early identification of psychopathology; for this reason, developmentally appropriate, reliable, and valid questionnaires are needed to gather their information. This study was designed to examine the utility of the Infant Toddler Social Emotional Assessment (ITSEA), a parent‐report questionnaire covering a wide range of behavior and emotional problems and competencies, in preschoolers referred for child psychiatric evaluation. The fathers and mothers of 85 children (23.2% girls; age 15–57 months) with autism spectrum, externalizing, or internalizing disorders completed the ITSEA, the Child Behavior Checklist (CBCL/2–3 and 4–18 versions), and the child domain of the Parenting Stress Index (PSI). The ITSEA showed good interrater reliability between parents, and validity was supported by significant correlations with corresponding CBCl and PSI domains. Evidence supporting the validity of the ITSEA for psychopathology was mixed across scales, with good diagnostic accuracy at the level of the broader psychiatric syndromes being achieved by the combination of subscales within the Externalizing, Internalizing, and Competence domains. The value of the ITSEA lies in the ability to systematically evaluate a wide range of problem behaviors and competencies. The ITSEA may be useful to create profiles of children's functioning in preschoolers referred for psychiatric assessment.     

Neuroticism and responses to social comparison among cancer patients

The present study examined how the effects of three audiotapes containing different types of social comparison information on the mood of cancer patients depended on the level of neuroticism. On the procedural tape, a man and woman discussed the process of radiation therapy, on the emotion tape, they focussed on emotional reactions to their illness and treatment, while on the coping tape they focussed on the way they had been coping. A validation study among 115 students showed that the tapes were perceived as they were intended. The main study was conducted among 226 patients who were about to undergo radiation therapy. Compared to patients in the control group, as patients were higher in neuroticism, they reported less negative mood after listening to the procedural and the coping tape. Furthermore, as patients were higher in neuroticism, they reported less negative mood after listening to the coping tape than to the emotion tape. Copyright © 2009 John Wiley & Sons, Ltd.     

Does marriage protect older people from distress? The role of equity and recency of bereavement

The association between marital status and distress was examined in a largely neglected group, namely older people (65 and older; N = 1,649). In this 2-wave study, married persons were less distressed than single persons, but perceived equity within the marriage and recency of bereavement qualified these findings. Married persons who felt inequitably treated were more distressed than persons who had always been single. Married persons reported less distress than recently (= 2 years ago) widowed persons, but only equitably treated married persons reported less distress than persons widowed for more than 2 years. Increased distress between the 2 waves occurred in recently widowed persons, and there was a decrease in distress in persons who were widowed shortly before the 1st wave. No gender effects were found.     

Differential involvement of hippocampal calcineurin during learning and reversal learning in a Y-maze task

The regulation and function of the calcium-dependent phosphatase calcineurin (CaN, protein phosphatase 2B) in learning and memory remain unclear, although recent work indicates that CaN may play a differential role in training and reversal training. To gain more insight into the involvement of CaN in these two types of learning, hippocampal CaN activity, protein levels, and expression patterns were studied in mice subjected to a reference memory version of the Y-maze task. We show that (1) training but not habituation induces a decrease in cytosolic CaN activity, (2) the recovery of cytosolic CaN activity is reversal training specific and does not reflect normal restoration of basal levels unrelated to subsequent learning, (3) cytosolic protein levels for the catalytic subunit of CaN (CaNA) are decreased at the early phase of training, but not at the early phase of reversal training, (4) CaNA immunoreactivity in the dorsal hippocampus is enhanced in the CA1 and CA3 area (but not in the dentate gyrus [DG] or subiculum [SUB]) only during reversal training. These findings indicate that memory formation is accompanied by reduced CaN activity, whereas adapting to changes in a familiar environment is accompanied by restored CaN activity. Moreover, reversal training selectively affects hippocampal CA3 and CA1 regions, suggesting a specific function of these hippocampal subregions in reversal learning.
