Economic status of families living with multiple sclerosis.

A nation-wide survey of 604 families living with multiple sclerosis was conducted. The sample was recruited through local chapters of the National Multiple Sclerosis Society and the public press. This paper describes the economic impact of the disease on families. There were 427 families in which the woman had multiple sclerosis and 177 families in which the man had the disease. The average duration of the disease was 10 years. Family income was well above the national median income. Thirty-nine per cent of the men and 19% of the women with multiple sclerosis retired because of disability. Income was inadequate to pay for medical expenses in 21% of the families and 25% had inadequate funds to meet basic living expenses. While 80% of the families had health care insurance, for 28% of the families the insurance was inadequate to cover the cost of their illness. The number of children living at home and the amount of health care bills paid out-of-pocket failed to explain why families in the high income group had difficulty meeting their expenses. Factors other than income and proportion of medical expenses covered by insurance determine the economic impact on the family. If health care providers are going to meet all the needs of a family living with multiple sclerosis, a more comprehensive assessment of their economic status is needed.

Descriptions and perceptions of health among rural and urban adults with multiple sclerosis.

The purpose of this study was to compare the health descriptions and perceptions of adults with multiple sclerosis living in rural and urban areas. Data were obtained from 361 adults, who responded to a mail survey including standardized self-report measures of physical and mental health, disability and social support, and an open-ended question on the meaning of health. In contrast to findings with general, nonclinical populations, the health perceptions and descriptions of this chronically ill population were not significantly affected by their place of residence. Further research is needed to examine the applicability of health-related findings from general populations to persons who are chronically ill.

Rural nursing: developing the theory base.

Many health care needs of rural dwellers cannot be adequately met through the use of existing nursing models alone but require unique approaches emphasizing the special needs of this population. The development of an integrated theory base for rural nursing is necessary. A retroductive approach, building upon both qualitative and quantitative research data, is being used to develop a theory of rural nursing. Key concepts identified are: work beliefs and health beliefs; isolation and distance; self-reliance; lack of anonymity; outsider/insider; and old-timer/newcomer. Implications for practice include the importance of relating health care to work practices and the need to intervene indirectly through established informal systems.

Social support and the chronically ill individual.

Nurses caring for the chronically ill need to be alert for the problems of social isolation and social impairment. Families often respond initially to serious illness by becoming over-protective and fostering dependence and a sense of impaired competence in the ill person. As the illness continues, families often experience exhaustion because of the demands of new roles, depleted finances, and other aspects of a changed lifestyle. Feelings of anger, guilt, and helplessness occur in the network, often leading to withdrawal of support--especially as the ill person's ability to reciprocate support is impaired. Nursing interventions in situations of social isolation focus on reducing isolation by promoting social interaction as appropriate, and by directly or indirectly mobilizing or expanding the social network. The problem of impaired social interaction may occur secondary to the personality changes that often accompany chronic illnesses, or as a function of the chronic illness or disability itself, as in the case of mental illnesses. Social impairment is an appropriate nursing diagnosis in abusive families. Nursing interventions range from educational programs for social skill development to reduction of the amount of contact within the network to involvement of protective and psychotherapy services. Chronic illness has profound effects on social support and the social network of both the ill person and his or her family. As both long-term illnesses and family involvement in care giving increase, nursing care in situations of chronic illness must include attention to issues of social support. Nursing diagnosis provides a framework for nurses to include social support in their care of the chronically ill patient. Social isolation and social impairment can be reduced by nursing interventions.

Resistance to natural killer cell-mediated cytolysis by a pleiotropic drug-resistant human erythroleukemia (K562-R) cell line.

K562-R, a pleiotropic drug-resistant cell line established in vitro, and K562-S, the chemotherapy-sensitive parent line, were used as targets in the natural killer cell (NK) system. At each of the effector:target ratios studied, the K562-R demonstrated a decrease in their susceptibility to both unstimulated and interferon-activated NK cells, as compared to the K562-S line. This difference did not appear to be related to a variable expression of NK target structures, as the number of effector:target conjugates was similar, and both lines competed equally well in cold target inhibition experiments. The K562-R cells were not resistant to complement or monocyte-mediated killing, suggesting a relatively specific resistance to cell-mediated killing. These results are compatible with an NK postbinding defect in the K562-R cells and suggest that greater tumorigenicity for pleiotropic drug-resistant cells may in part be due to altered susceptibility to host defense.

Evaluation of the Personal Resource Questionnaire: a social support measure.

The purpose of this study was to further the psychometric evaluation of the Personal Resource Questionnaire (PRQ). The PRQ was developed to measure social support as a multidimensional construct. The PRQ is a two part measure of social support. Part 1 consists of life situations in which one might be expected to need some assistance. It provides descriptive information about the person's resources, whether or not they have experienced the situation in the past 6 months, and their satisfaction with these resources. Part 2 contains a 25-item Likert scale that measures the respondent's level of perceived social support. The questionnaire can be self-administered, requires approximately 10 minutes to complete, and is easily scored for use with various statistical techniques. Based on data generated by the author and on three additional data sets provided by collaborating researchers, psychometric properties of the PRQ were investigated. There was sound evidence to rule out the explanation that the respondent's answers on the PRQ reflect a reporting simply of socially desirable answers. There were no significant differences between the scores for women and the scores for men on either Part 1 or Part 2 of the PRQ. Evidence was provided to substantiate criterion-related validity. Part 2 of the PRQ was predictive of dyadic consensus. Likewise, initial validation of construct validity was evident. Part 2 of the PRQ is correlated with mental health indicators. Yet, the analyses indicate that there is reason to believe that the PRQ is not simply another way of measuring the construct of depression and anxiety. Consistently strong estimates of reliability, determined by the use of Cronbach's alpha, were obtained indicating a high level of internal consistency for the PRQ-Part 2. This report of the early psychometric evaluation of the PRQ can provide researchers with information which can guide their use of this social support measure. There are now some established base line profiles of responses for comparisons. The validity and reliability of the PRQ are sufficiently established so as to permit the continued use of the tool with some level of confidence in interpreting the results.

[Functional and cosmetic results in thumb replacement surgery].

The operations to replace the thumb have been proved in thalidomide embryopathy both functionally and cosmetically. The best results are achieved in the pollicisation of dolichophalangeal triphalangeal thumbs. Simultaneously existing radial club hand impairs the operative results considerably.

Measures of social support: assessment of validity.

The evidence of construct validity that resulted from conjoint testing of two measures of social support, the Personal Resource Questionnaire (PRQ85) and the Cost and Reciprocity Index (CRI) is presented. Both instruments were used with two samples of adults, 333 who were part of a large health project and 99 who participated in a methodological study. The PRQ85 and CRI appear to tap the construct of support yet are not highly redundant. Both tools demonstrated similar curves of relationships to external criteria. Dissimilar patterns of relationships with negative mood states indicated an area of need for future study.

A social support measure: PRQ85.

The Personal Resource Questionnaire (PRQ) was developed in 1981 to measure situational and perceived social support. This article presents the history of its development and the latest psychometric evaluation of the tool. Nurturance subscale items were rewritten to reflect a broader context of behaviors toward persons of any age. Content validity was further established by correlations between the PRQ and two mental health measures. Factor analysis indicated that a three-factor structure for the perceived social support scale may be more appropriate than the hypothesized five-subscale structure.
