Reminiscence, life review, and ego integrity in nursing home residents.

The purpose of this study was to explore the relationship between dimensions of reminiscence and ego integrity in elderly nursing-home residents. Although frequency of reminiscence was not significantly correlated with ego integrity, using reminiscence for the purpose of life review was positively correlated with high ego-integrity scores in this sample of elderly individuals. This significant, positive relationship supports Butler's life-review theory and provides a link between the life review type of reminiscence and the resolution of Erikson's eighth and final developmental stage--a yardstick of successful aging.

Social relationships, psychosocial adaptation, and intrainstitutional relocation of elderly men.

The intrainstitutional relocation of 40 men aged 53 to 91 years was studied in relation to social integration, and to behavioral and self-report measures of psychosocial adaptation. In both longitudinal and time-lag analyses of pre- and postrelocation data, relocated men scored lower on the attitude toward aging dimension (PGC Morale Scale, Lawton, 1975), had fewer friends, and evidenced better communication behavior (p less than .01) than did unrelocated men. The more sociable men showed more change after relocation than did men who were less sociable.

Life-span differences in life satisfaction, self-concept, and locus of control.

The literature on age differences in life satisfaction, self-concept, and locus of control reveals a variety of conflicting findings. Nehrke et al. reported a study of elderly institutionalized males that attempted to control for some of the possible sources of variability. The present study extended this effort to a noninstitutionalized life-span sample of males and females in six age groups (fourteen to ninety-four). The age main effect was significant for the locus of control measure. For self-concept, the age and sex main effects were significant. For life satisfaction, the age and sex main effects and their interaction were significant. Generally, lower levels of self-concept and life satisfaction and a more external orientation characterized adolescents and young adults while, with notable exceptions, the remaining age samples were more positive in self-concept and life satisfaction and were more internally controlled. Although the three dependent measures were significantly correlated for the total sample, the correlations involving locus of control were only moderate. The data suggest that at least the life satisfaction and self-concept measures may be viable tools to assess the psychological quality of one's life, and that reliable age differences in well-being can be demonstrated if moderating variables are controlled experimentally or statistically.

Mediators of estimates of brief time intervals in elderly domiciled males.

Conflicting interpretations questioning whether brief intervals of real time are perceived as passing more or less rapidly with increasing age have been reported. Reasons for these inconsistent results lie in semantic confusions, in variations in methodology, and in the effects of other mediating variables. The present study examined relationships between age, value of time over both the short and the long term, perceived time to death, self-perceived activity levels, and estimates of brief time intervals in a sample of older institutionalized males. The production method was used to obtain the estimates of time passage. Time intervals were increasingly underestimated with advancing age, indicating that time units are shorter with increasing age. While a number of other variables were interrelated, the only other factor consistently related to time estimates was the short-term value of time. Implications for future research and for interventions in institutional settings are discussed.

The relationship between problem solving and activity level in the elderly.

Research stemming from disengagement and activity theory has recently focused on individual differences in establishing and maintaining interpersonal relationships. A specific intervening variable which has been hypothesized to be related to social activity level is interpersonal cognitive problem solving skills (ICPS). The present study identified two groups of elderly veterans on the basis of their ICPS skills. Those who generated a high number of solutions to interpersonal problems reported significantly more time spent in social and isolated goal-directed tasks than the group generating fewer solutions when age, educational level, and length of institutionalization had been covaried. The results suggest the potential usefulness of the ICPS approach as a means of identifying socially active individuals and as an intervention or training technique for less able institutionalized residents.

Toward a model of person-environment congruence: development of the EPPIS.

The Person Environment (P-E) Congruence model represents an approach to understanding the impact of the environment on the well-being and adjustment of elderly which may also provide information for the development of intervention programs at individual, group and/or institutional levels. Assessment of P-E congruence, or fit between the person and his/her environment, was operationalized in two studies through the development of the Environmental Perception, Preference and Importance Scale (EPPIS). the EPPIS provides scales to assess environmental perceptions, individual environmental preferences and the important or salience of the environment on 15 empirically derived, commensurate dimensions. In a third study, the four-month test-retest reliability of the overall P-E congruence score of the EPPIS, defined as the absolute difference between the perceived and preferred environment weighted by importance, was .78 while the unweighted model reliability was .76. Also, the 15 dimensions of the EPPIS were observed to be significant predictors of well-being. It was proposed that the EPPIS may be used both to determine areas of intervention which the elderly themselves feel are important and as a means to evaluate the effectiveness of interventions intended to reduce P-E incongruence and increase psychological well-being.

Determinants of person-environment congruence in institutionalized elderly men and women.

This study was designed to obtain information potentially of value in understanding an modifying the impact of the social environment of the perceived quality of like among institutionalized aged persons. It was hypothesized that Person-Environment (P-E) congruence, as assessed by the Environmental Perception, Preference and Importance Scale (EPPIS), would be related to (1) sex integration/segregation makeup of the health related facility (HRF) living units, and (2) quantity of social interaction between staff and residents. Analysis of sex by unit sex-type interaction for 60 residents' Person-Environment (P-E) congruence scores revealed that elderly females on sex-integrated units reported a higher level of P-E congruence than those residing on female-only units; males on sex-integrated units, in contrast, reported a poorer level of P-E congruence than males on sex -segregated units. Furthermore, behavioral observations of staff-resident verbal interactions confirmed the hypothesis that residents living on units with high staff-resident interaction perceived the environments more congruent with their preferences than residents on units low in verbal interaction. The observed relationships between the P-E congruence measure, resident-staff interaction, and unit sex-type were taken as further support for the relevance and value of the EPPIS measure as a tool for assessing and improving the institutional milieu.

Friendship, social interaction and subjective well-being of older men in an institutional setting.

The relationship of informal social interaction to subjective well-being of older adults was investigated using the PGC Morale Scale, the MACC Behavioral Adjustment Scale, and a sociometric interview which provided measures of peer friendship and frequency of social interaction. Respondents were fifty-four males aged fifty-two to ninety years, who were residents of a Veterans Administration domiciliary. The predicted positive correlation was obtained between morale and frequency of social interaction with persons outside the institution, but men's friendships within the institution were not related to morale. As expected, men who reported overall change in frequency of social interaction scored substantially lower on the PGC Morale Scale than those who perceived no change. Behavioral adjustment ratings of participants made by a staff member were positively correlated with friendship and social interaction scores. The results were thus consistent with a continuity model of aging, in which maintenance of accustomed levels of social interaction is related to subjective well-being.

Resident and staff perceptions of latitude of choice in elderly institutionalized men.

Ninety-nine elderly institutionalized males, selected equally from three decades, completed measures of: their personal, perceived latitude of choice (LOC) in activities of daily living; self-concept; and life satisfaction. One hundred staff, of both sexes, estimated how the typical or "average" V.A. domiciliary resident would respond to the LOC measure. Mean resident LOC scores were found to be significantly related to life satisfaction but not to self-concept. This supports the thesis that latitude of choice, or personal autonomy, is related to well-being and that the LOC measure may be a useful tool in the development and evaluation of interventions aimed at improving resident well-being. Significant relationships between resident age and the importance of daily activities, self-concept and life satisfaction were also observed although there were no age differences in the resident data for the LOC, importance or choice measures. In comparing staff attributed and resident perceived latitude of choice, significant differences were found. Examination of response patterns to the specifically listed activities of daily living also revealed significant staff-resident differences. Therefore, any attempt to intervene in the environment to increase the personal autonomy or control of residents, and hence their well-being, must deal with such staff-resident differences and with staff misperceptions of what is and is not important to residents. Interventions should be targeted at specific activities viewed by a majority of residents as restricted and insofar as practical, interventions should be individually tailored.

Age differences in life satisfaction, locus of control, and self-concept.

The literature regarding age differences in life satisfaction, locus of control and self-concept reveal seriously conflicting results while that on the relationships among these dependent measures has largely supported Erikson's proposals regarding the psychosocial crisis of ego integrity versus despair. A total of ninety-nine V. A. Domiciliary residents, with thirty-three in each of three age groups (50-59, 60-69 and 70+), completed measures of life satisfaction, locus of control and self-concept. Multivariate analysis of covariance demonstrated a significant age difference with the older veterans, who were less well educated and institutionalized longer, more positive on the composite of the three measures. Univariate analysis, however, resulted in significant age differences in self-concept and life satisfaction but not in locus of control. Based upon these findings and the relationships among the dependent variables, the older veterans appear to have resolved the ego integrity versus despair crisis more adequately in spite of having lived for a longer period of time in what has often been viewed as a sterile, blunting environment. Perhaps, contrary to popular assumptions, an institution may provide an environment that facilitates and nourishes the self-esteem and satisfaction of elderly residents.

Age Factors

The effects of overtraining on mediational processes in elderly males.

To examine the effects of overtraining on mediational processes, 81 male residents (aged 55 or above) of a VA domicillary were tested using a two-choice discrimination task. Upon reaching criterion, the men were given, 0, 15, or 30 overtraining trials and then shifted to either a reversal, intradimensional, or extradimensional task. Analysis of the error scores resulted in a significant initial versus shift task main effect and type of shift by initial versus shift task interaction. Further analysis indicated no difference among the three shift groups for the initial task. However, in the shift task, the reversal group had significantly fewer errors than the other two groups who were not statistically different. Participants thus appeared to be mediationally sufficient when reversal and extradimensional tasks were compared, but mediationally deficient when intra- and extradimensional, and reversal and intradimensional tasks were contrasted. While overtraining had no significant effect, examination of the three way interaction suggested potentially facilitative effects of overtraining and a possible regression effect among participants not receiving overtraining.

Cognitive egocentrism in institutionalized adult males.

Spatial egocentrism and its relationships to discrimination ability and communicative egocentrism were investigated in a sample of 80 adult males from a single institutional setting. The participants ranged in age from 33 to 83 years. As predicted, no significant age differences were obtained on any of the three dependent measures. However, significant effects of order of task presentation indicated that the experimental procedure influenced performance on the spatial and communicative egocentrism and discrimination tasks. The findings, which provide support for the Piagetian position of maintenance of operational level through the life-span, were discussed in terms of social and affective factors which may influence adult performance on cognitive tasks.

Partitioning chi-square the analysis of contingency tables with repeated measurements.

Categorical variables are commonly used in gerontological research. Although analysis of such variables presents no problem as long as the observations are independent, problems do arise when they are found in a design with repeated measurements. In this paper, two procedures from the statistics literature are combined to provide an analysis for data from a mixture of between and within categorical variables. First, a response pattern is used to form a contingency table with observations which are completely independent. Next, the Pearson chi-square statistic from the table is partitioned to provide tests analogous to simple effects in analysis of variance.
